▼ The cardiac plexus is “formed by mixed autonomic nerves” that are “described in terms of superficial and deep components, with the superficial located below the aortic arch and anterior to the right pulmonary artery, and the deep located anterior to the tracheal bifurcation (above the division of the pulmonary trunk) and posterior to the aortic arch” (Standring et al., 2008). This investigation aims to review and update the medial cardiac contributions of the cervical and thoracic sympathetic chains to the cardiac plexus and also the contributions from the vagus nerve and its counterpart, the recurrent laryngeal nerve. This study involved the macro and micro-dissection of 100 cadaveric sides of adult and fetal material.
The number of ganglia in a cervical sympathetic chain varied from 2 to 5 in this study. This study confirms previous reports on the location of the two components of the cardiac plexus. The origin of the sympathetic contributions to the cardiac plexus in this study were either ganglionic, interganglionic or from both the ganglion and interganglionic chain of the respective ganglia. The superior cervical cardiac nerve had an incidence of 92% while the middle cervical cardiac nerve had an incidence of 65% in the specimens studied. This study also records a vertebral cardiac nerve that arose from the vertebral ganglion in 39% of the cases. The inferior cervical and cervicothoracic cardiac nerves had incidences of 21%, respectively. This investigation records the thoracic caudal limit of the sympathetic contributions to the cardiac plexus as the T₅ ganglion.
The findings in this study indicate the importance of understanding the medial sympathetic contributions and their variations to the cardiac plexus as this may assist surgeons during minimal surgical procedures, sympathectomies, pericardiectomies and in the management of diseases like Reynaud’s Phenomenon and angina pectoris (Kalsey et al., 2000; Zhang et al., 2009).

▼ Stature estimations from regression formulae are used by forensic anthropologists in constructing a biological profile from unidentified human remains. Regression formulae are used to calculate total skeletal height or living stature when incomplete, fragmentary or burned human remains are recovered. This study aimed to evaluate the reliability of the total skeletal height regression formulae from (1) Lundy and Feldesman (1987), and (2) Dayal et al. (2008) when compared to total skeletal height from the full anatomical method (Fully’s method), in a contemporary South African population. The use of these regression formulae to estimate total skeletal height of South Africans of Mixed Ancestry was investigated as no population-specific standards exist for this group. Additionally, the reliability of the generic femur/stature ratio (Feldesman et al., 1990) to estimate living stature for all three population groups was investigated. Measurements were taken from 229 individuals comprising of South Africans of Mixed Ancestry, African Descent and European Descent from South African skeletal collections. ANOVA’s and paired t-tests were used to determined if there was a significant difference (p<0.05) between (1) estimated total skeletal height from regression formulae and that from Fully’s method, and (2) the estimated living stature from the femur/stature ratio and a calculated living stature from Fully’s total skeletal height with soft tissue and age correction factors. No significant difference (p>0.05) was found between South Africans of African Descent and Mixed Ancestry’s calculated total skeletal height, but both were significantly different (p<0.000) to individuals of European Descent. Results indicate that the Lundy and Feldesman (1987) regression formulae should be re-assessed for contemporary South Africans of African Descent and results from the Dayal et al. (2008) regression formulae indicate that the formulae are still relevant for contemporary South Africans of European Descent. Additionally, new regression formulae should be developed to enable forensic or physical anthropologists to estimate total skeletal height of Mixed Ancestry individuals. The femur/stature ratio’s living stature were significantly different (p<0.000) from the calculated living stature, and generally overestimated it for maximum femur lengths greater than 50cm.

▼ Ancestry estimation is a critical component of the demographic profile compiled by forensic anthropologists when unknown skeletal remains are discovered. The mid-craniofacial region is most frequently used to estimate ancestry as this region reflects the genetic and morphological ancestry of an individual. The diverse composition of the South African population makes ancestry estimation problematic, and necessitates the development of reliable, population-specific standards. This study sought to characterise variations in mid-craniofacial shape and size between South Africans of European ancestry (EA), African ancestry (AA) and Mixed ancestry (MA). Metric, nonmetric and geometric morphometric assessments were performed on 392 crania from skeletal collections in South Africa. Variations in mid-craniofacial shape and size were assessed in the orbital, nasal, zygomatic and maxillary regions in two-and three-dimensions. Univariate and multivariate statistical analyses were employed to characterise variation and estimate ancestry in AA, MA and EA individuals. Multivariate analyses suggest that tightly integrated ancestral variations in each component of the mid-craniofacial region are associated with functional, regional and developmental proximities of these regions. Specifically, AA individuals exhibited wider and shorter midfacial regions than EA individuals, who exhibited the narrowest orbital, zygomatic and nasal breadths and the longest upper facial, orbital and nasal heights. EA individuals exhibited inferiorly-angled orbits, elongated nasal apertures and anteriorly projecting nasal bridges. Rounder nasal apertures, less anteriorly projecting nasal bridges and more anteriorly projecting maxillary regions were detected in AA individuals. MA individuals exhibited heterogeneity in terms of craniofacial shape and size, and therefore produced the lowest ancestry estimation accuracies. Overall, nasal and maxillary regions were the most ancestrally diverse regions. Antemortem maxillary tooth loss and midfacial trauma were confounding factors in ancestry estimation accuracies. The lowest ancestry estimation accuracies were yielded by two-dimensional metric (27%-60.2%) and nonmetric (57.1%-82.4%) methods. Metric and geometric morphometric assessments yielded the highest repeatability (≥ 95%) indicating that these methods may be more reliable for use in medicolegal contexts. Geometric morphometric shape assessments yielded the highest ancestry estimation accuracies (75-97.9%), suggesting the presence of three dimensional shape variations between ancestry groups. These results suggest that a continuum of ancestral variation, with large areas of overlap, exists across South African populations and emphasises the need to develop multivariate ancestry estimation standards which can estimate ancestry reliably.

▼ Although it is a reasonable assumption that a significant proportion of the variation in facial tissue thicknesses comes from anatomical differences between populations, we do not know how much of normal variation is caused by including the full range of individual obesity or slimness. Current population standard soft tissue thickness data used in facial reconstructions ignores the variation between individuals which, in theory, could be greater than the variation between populations or sexes. The aim of this study was to test if facial tissue thickness is due to the amount of sub - cutaneous fat, sex or racial origins. Methods currently used do not give a true reflection of the individual because they ignore the variation in fatness. An initial study determined if a corrective value for the non - linear distortion found between radiographic images and the physical tissues was needed. This was done by imaging cadaver heads and taking measurements from the images and the physical heads. The results demonstrated that measurements taken from LODOX® images are analogous with soft tissue measurements. Volunteers were then sought from the student body and had physical measurements and X - rays taken. The measurements allowed for both BMI and body fat percentage to be calculated. Analysis showed that body fat percentage had less of an impact than BMI, with the areas of the face most affected by change in fatness being around the chin, jaw and cheek. Analysis of the variances showed that fatness has a low impact on the soft tissues of the different ancestry groups, while having a greater impact on the soft tissues of the different sexes. The effect of changing fatness on the soft tissues is not seen in all areas of the face, but to ignore it in facial reconstruction ignores that the success of a reconstruction is not exactness but in its ability to incite recognition and lead to potential identification of the unknown target individual.

▼ INTRODUCTION This project investigated volumetric differences in certain subcortical structures as measured on high-resolution structural Magnetic Resonance Imaging (MRI) scans traced manually. The sample comprised 79 5-year old children, 52 with HIV and 27 uninfected controls. Infected children were all stable on antiretroviral therapy (ART) and were from the Children with HIV early antiretroviral (CHER) cohort who have been followed since birth. The study aimed to investigate the long-term effects of HIV and ART on the developing brain. While high-resolution structural data has been analysed using automated FreeSurfer to determine volume and cortical thickness, manual tracing remains the gold standard. Thus, manual tracing was used to validate automated measures and investigate subtle group differences in selected regions of interest. METHODS Extensive clinical data were available for all participants in the study. MR images were AC-PC transformed and converted to analyse format. Structures were traced using MultiTracer software. Structures selected included the caudate, nucleus accumbens (NA), putamen (Pu), globus pallidus (GP) and corpus callosum (CC). Four of these structures occur bilaterally. Tracing was performed in 79 subjects. Three subjects were excluded due to poor quality images or pathology; 5 HIV-1 infected children were excluded as they were not randomized between treatment groups. Certain subjects were retraced for inter and intrarater reliabilities. The effect and association of ethnicity, age, birthweight and sex as possible confounders were investigated. As the groups were not well matched for ethnicity, all Cape Coloured children were excluded from further analyses. Analysis of variance was used to test the effect on structure size between HIV-1 infected children and controls, as well as between 3 treatment arms (ART deferred until clinical criteria were met, early ART for 40 weeks, early ART for 96 weeks) and uninfected controls. Analysis of covariance was used to control for the possible confounding effects of sex and age. Each structure was tested for possible association with clinical variables (CD4, CD8, CD4/CD8 ratio and CD4%) both at enrolment and time of scanning. Linear regressions were modelled using clinical variables that showed significant correlation with structure size whilst controlling for covariates. Congruence between automated FreeSurfer and manual segmentation were evaluated via Bland-Altman, Pearson r and Cronbach's alpha.

▼ Morphological variation of skeletal elements, and the potential use of such variation in distinguishing among demographic groups, is often investigated using traditional metric or non-metric assessments. Traditional approaches, however, often fail to sufficiently capture the "true" shape of features, thus also failing to identify potentially important feature characteristics. The development of geometric morphometrics has allowed more comprehensive and accurate three-dimensional data capture which maintains the geometric properties of an object while isolating the effect of size from the data. The aim of this study was to employ the geometric morphometric approach to a 3D digitized sample of 1132 South African individuals from the skeletal collections of the Universities of Cape Town, Stellenbosch, Witwatersrand and Pretoria. Morphological variation among demographic groups was assessed using Generalized Procrustes Analyses applied to the individual bones of the neurocranium and the long bones of the limbs. The ability to distinguish groups based on the detected variation was assessed using Discriminant Function Analysis. The results show that, when size is isolated from the data, only a few elements show sexual dimorphism, while all examined elements show high accuracy in distinguishing among ancestry groups (>74%). When variation is assessed using both parameters, classification accuracies of 70-83% are obtained. Comparison of the different elements shows that the best classification accuracies are based on the frontal bone (84% average) and the humerus (81% average). This study shows that the morphologies of the neurocranium and long bones vary among sex and ancestry groups. This allows assessment of how the combination of variable intrinsic and extrinsic influences can manifest on different parts of the skeleton. In a population as genetically and historically complex as that of South Africa, understanding of the impact of such influences may inform forensic assessments of skeletal material, which is especially valuable considering the high rate of violent crimes and increasing number of unidentified remains being discovered in the country.

▼ Llamas (Lama glama) appear to have predisposing anatomical features for developing
otitis media such as a long and narrow external acoustic meatus and a trabecular
tympanic bulla. However, there is limited information available about the morphology of
the ear in this species. The aim of this study was to evaluate the osseous structures of
external acoustic meatus, tympanic cavity and tympanic bulla using CT, and the soft
tissue surrounding the ear using dissections. Ten heads were collected from healthy
llamas slaughtered for meat production. Using a CT scanner with slices acquired at 1
mm, measurements of the bony structures of the external and middle ear of each head
were obtained. The surrounding soft tissue was examined using dissection, a 6-inch
protractor and a digital caliper. The osseous external acoustic meatus was ventrally
curved with an obtuse angle facing ventrally. Its narrowest portion was located medially
at the level of the tympanic annulus. The conformation of the tympanic bulla was the
most different in appearance compared to other domestic animals. It was divided into
caudo-lateral and caudo-medial processes, body, apex, and stylohyoid fossa to study its
morphometry. The interior of the tympanic bulla had a honeycombed structure with
pneumatized cells similar to the human's mastoid process. The nerves, vessels, muscles
and tendons had the general distribution of those structures in herbivorous domestic
animals. The present study supplied new information about the shape and measurements
of the osseous external and middle ear and surrounding soft tissue in adult llamas. This
study also supplied specific landmarks of the location of these structures in relationship
with each other. Based on our observations and measurements, a new surgical approach
to perform a tympanic bulla osteotomy was suggested to treat otitis media in llamas.

▼ Mast cells within the peripheral and central nervous systems of CBA and SJL mice during Theiler's virus-induced demyelination (TVID) have been investigated. CBA mice are intermediately susceptible and SJL mice are highly susceptible to TVIID. The two mouse strains were infected with the BeAn or DA strain of Theiler's murine encephalomyelitis virus (TMEV) or PBS (controls). One control mouse and two mice from each infected group (with a clinical score ranging from 2-5) were euthanized and the sciatic nerves and thalamic regions were collected for average mast cell counts. The SJL mice exhibited a higher incidence and degree of disease (based on clinical scores) than the CBA mice. SJL mice exhibited greater average numbers of mast cells within control sciatic nerves compared to CBA mice. However, CBA mice exhibited higher average number of mast cells within control thalamic regions compared to SJL mice. Within strain differences revealed that the CBA mice exhibited greater average numbers of mast cells within the sciatic nerves during DA infection of the CNS and within control and BeAn infected thalamic regions compared to SJL mice. Viewer's observations include heterogeneity among perivascular and periventricular mast cells of the thalamic regions, the presence of immature mast cells within the sciatic nerves, and possible mast cell/macrophage interactions during the demyelinating disease.

▼ Mercury (Hg) and lead (Pb) are toxic to the development and function of the central nervous system (CNS). Interleukin-6 (IL 6) produced by astroglia protects neurons from damage in many progressive degenerative disorders. IL-6 secretion is chaperoned by a 78 kD glucose-regulated protein (GRP78), which is an ER-chaperone protein involved in protein folding, assembly, and trafficking. We hypothesized that Pb and Hg could target GRP78 and thereby block IL-6 secretion from astroglia. In this report, we constructed an IL-6-EGFP chimera and transiently transfected rat C6 glioma cells and rat primary astroglia. IL-6-EGFP signal in transfected cultures exposed to Pb, Hg, or anti-oligos against GRP78 was detected with a bio-image fluorescence microscope. Data of the bio-image analysis showed that the retention of IL-6-EGFP in both astroglia and C6 cells transfected with IL-6-EGFP was at an undetectable level. However, the IL-6-EGFP signal in these cultures, while exposed to Pb (0-10 ưM) or Hg (0-10 ưM) for 24 hours, apparently increased, suggesting that Pb or Hg could block IL-6 secretion from astroglia. Furthermore, when these transfected cultures were exposed to anti-oligos against GRP78, as expected, the retention of IL-6-EGFP within the cultures increased. In order to quantify the increase of IL-6-EGFP retention, we used ELISA to detect IL-6 levels in the medium of non-transfected astroglia exposed to Pb (0-100 ưM) and Hg (0-10 ưM). Data showed that IL-6 levels in the medium decreased when the primary astrocyte cultures were exposed to Pb or Hg, suggesting that the increased retention results in part from a decrease in IL-6 secretion. We used an immunocytochemistry assay as an additional approach for quantifying IL-6 amounts of cells treated or not treated with metals. The immunocytochemistry data concurred with the ELISA findings. These data, together with our previous studies, suggest that Pb and Hg may target GRP78, thereby reducing the amount of IL-6 secreted from astroglia. The decrease in IL-6 secretion prevents this cytokine from doing its job of protecting and restoring neighboring neural tissue.

▼ In situ transcription and anti-sense RNA amplification (RT/aRNA), new techniques in molecular biology, were used to examine developmental expression of a panel of candidate genes in two separate studies. (1) Cranial and caudal neural tube tissue was isolated from LM/Bc embryos, which were collected from dams sacrificed on gestational day (GD) 9:12 or 1 0:0. Retinoic acid receptors (RAR-a), the potassium channel gene (Kvl), and the nicotinic receptor subunit al (NACHR) were developmentally regulated The level of expression for these genes changed significantly between GD 9:12 and 1 0:0. The expression of RAR-A increased in the neural tube with advancing gestational age while Kvl and the nicotinic receptor expression were significantly decreased over the same time period. Kvl and the sodium channel gene were expressed at higher levels in the cranial region of the neural tube on GD 9:12, while expression of NACHR was higher cranially at GD 1 0:0. Although relatively few statistically significant changes in the expression patterns between cranial and caudal neural tube regions were observed, these changes may represent fundamental differences in molecular processes which are responsible for neural tube development among different regions of the neural tube. (2) LM/Bc females were treated with 5 mg/kg all-trans retinoic acid (RA) on GD 8:12. On GD 10:0, 10:1 2, or 12:0, untreated and RA-treated dams were sacrificed, and the embryos were recovered. First and second bronchial arches from each embryo were utilized for RT/aRNA studies to explore differences in gene expression which may lead to congenital malformations in second branchial arch derivatives of RA exposed fetuses. Significant differences in the level of expression between the first and second bronchial arches were observed. The expression of the type-1 cellular retinoid binding protein, the CAMP response element-binding protein, NACHR, RAR-Y, and transforming growth factor P2 were increased following RA exposure. The application of RT/aRNA techniques have allowed for the investigation of coordinate changes in gene expression which occurred within specific embryonic structures during development.

▼ In vitro cell model systems derived from rat granuloma cells were developed for the study of multistep ovarian carcinogenesis. Spontaneously immortalized rat granuloma cells (SIGC) were transfected with either the pSV3neo plasmid which contains the SV40 early region genes (SV-SIGC) or the plasmid containing the Her-21neu oncogene (neu-SIGC). Additionally, SIGC were continuously passaged in culture. The three cell model systems were evaluated according to structural and functional alterations associated with the transformed phenotype. SV-SIGC cells were injected into nude mice and the resulting tumors were expanded into an additional cell line (T-SVSIGC). Utilizing indirect immunofluorescence and monoclonal antibodies, the expression of desmosomes and associated cytokeratins in SV-SIGC was lower when compared to SIGC, but T-SV-SIGC showed the most dramatic decrease compared to SIGC. SIGC subject to low calcium medium showed a dramatic reduction of desmoglein staining at cell-cell borders, as well as, single cell migration in the wound healing assay. Additionally, gap junctional intercellular communication (GJIC) was reduced in a step-wise fashion in the SIGC-> SV-SIGC-> T-SV-SIGC system. SIGC transfected with the neu oncogene were anchorage-independent, as shown by soft agar assay. The cytokeratin pattern density was diminished in the neu-SIGC and also showed decreased desmosome expression when compared to SIGC. GJIC was also significantly reduced in the neu-SIGC when compared to the parental line SIGC. GSH was elevated in neu-SIGC compared to SIGC. Late passage SIGC readily formed clones in soft agar and showed a decrease in desmosomal and cytokeratin associated protein organization. They also exhibited a decrease in the rate of GJIC and an increase in glutathione levels compared to low passage (23) SIGC.

▼ Heavy metals are naturally occurring elements with global distribution. Industrial application of some heavy metals has led to ecosystem contamination and accumulation of unsafe levels in the food chain, even for those metals which normally function in organism homeostasis. Levels of heavy metals in tissues of the Atlantic bottlenose dolphin (Tursiops truncatus) from the Texas coast of the Gulf of Mexico have not been systematically explored. The large population of this species along the Gulf coast, their rather long lifespan and the high position of this species on the food chain permit the bottlenose dolphin to serve as a measure of metal dynamics within the Gulf. For this study, seven heavy metals (Cd, Cu, Fe, Hg, Pb, Se and Zn) were determined in liver, kidney, muscle, blubber and bone of bottlenose dolphins stranded along the Texas coast and in liver of those stranded along the Florida Gulf coast. Concentrations of all tested metals were comparable to those previously reported for populations of bottlenose dolphins in other geographic regions. Two metal-metal correlations were examined in liver, kidney and muscle tissue. Strong positive correlations were found between mercury and selenium in the three tissues. No correlations existed between cadmium and zinc. The effects of age, location and gender on metal concentrations were also analyzed. Because age was not available for all animals, a separate model was used substituting length for age. Length and age had the greatest impact, significantly associated with the concentrations of cadmium, mercury, lead and selenium. Copper was associated with gender in the kidney. Mercury was associated with geographic location in the muscle when the length model was used and in the liver when the age model was used.

▼ Toxic effects of lead (Pb) have been recognized for as long as the heavy metal has been used in society; however, Pb toxicity is still a problem today in humans and animals. The primary targets of Pb toxicity are the hematological, renal and neurological systems. One of the best ways to prevent systemic Pb toxicity from an ingested source may be to reduce absorption of Pb from the gastrointestinal tract into the blood stream. Unfortunately, little is known about the mechanisms of Pb absorption through the intestinal epithelium. Using two established intestinal epithelial cell lines, IEC-6 and Caco-2, we studied the effects of temperature, metabolic inhibitors, sulfhydryl group modifiers, blocking of integrins with the tripeptide Arginine-Glycine-Aspartate (RGD), and induction of metallothionein by zinc on the total cellular accumulation of Pb. We have shown that the uptake of Pb into IEC-6 cells involves a potentially energy-independent pathway which may utilize sulfhydryl groups and integrins. We have also demonstrated that Pb is extruded from the IEC-6 cells by means of an energy-dependent mechanism. Additionally, in Caco-2 cells we demonstrated that induction of metallothionein by overnight exposure to zinc resulted in an increased total cellular Pb content, suggesting that metallothionein sequesters Pb in the cytosol. This is the first report of the use of intestinal epithelial cell lines to study the absorption of Pb. Understanding the mechanisms of Pb uptake will provide potential methods to prevent the absorption of ingested Pb into the systemic circulation.

▼ Nitric oxide (NO) is generated from L-arginine by different isoforms of the enzyme nitric oxide synthase. (NOS) and is known to be involved in mediating several biological functions, some of which are associated with reproduction. Much attention has been given to discerning the role of the NOINOS system regarding hypothalamic-pituitary hormone secretions with less attention devoted to discerning its presence or potential functions in the ovary-Recent data, using NOS inhibitors both in vivo and in vitro, as well as NO donors in vitro, suggests that NO may be involved in ovarian function. However , neither the presence of NOS mRNA nor the potential change in NOS gene expression relating to pre-and postovulatory events have been reported. Because of our interest in ovarian function at the time of puberty, we examined in the present study whether the ovary expresses both the inducible (i) and constitutive (c) forms of NOS and whether either form undergoes changes in the ovary during the phases of peripubertal development. Results indicate that both forms of NOS were expressed in the ovary and that the INOS MRNA transcripts were expressed without being exogenously induced. Importantly, when compared with juvenile levels, INOS, but not CNOS, MRNA increased (p<0.01) during the early proestrous phase of development. By the late proestrous phase, the levels of INOS MRNA declined markedly (p<0.001) and remained low throughout both the first estrous and diestrous phases. Furthermore, Western blot analysis revealed both INOS and CNOS protein expression in each phase of puberty with only INOS showing a significant change during the peripubertal period. Specifically, there was an initial increase in the expression of INOS protein during the late proestrous phase (p < 0. 05) which was accompanied by preovulatory increases in serum estradiol (p<0.01) and LH (p<0.001). The INOS protein levels dramatically increased again to peak on the morning of first estrus (p<0.001), i.e. a few hours after ovulation, an event associated with declining (p<0.05) serum levels of estradiol. These data are the first to demonstrate developmental changes in the expression of ovarian INOS MRNA and protein both before and after first ovulation; hence, suggesting a role for NO in the ovary during pubertal maturation and furthermore, providing compelling evidence at the gene level supporting the hypothesis that the NOINOS system plays a physiological role in ovarian function.

▼ Multiple sclerosis (MS) is a chronic inflammatory graphics. disease of the central nervous system (CNS), leading to demyelination within the CNS, and is responsible for the progressive neurological deficits associated with MS (Stinisen et al., 1997). One of the best animal models of MS is the demyelination induced by Theiler's virus. The early events that occur during Theiler's virus infection are crucial in the effective clearance of virus from the CNS. Failure to clear virus results in the establishment of persistent infection of the CNS and subsequent demyelination (Brahic et aI., 1981 ; Rodriguez et aI., 1996). A growing body of evidence indicates that physical and psychosocial stressors compromise immune function (Ader et aI., 1991). An individual's response to a stressor is manifested in physiological, hormonal, behavioral, and immunological changes. Since the earliest descriptions of multiple sclerosis, stress has been considered a controversial, but potentially important, factor in the onset and course of the disease. Recent studies using standardized assessment of life events have begun to shed light on the idea that psychological stress precedes both the onset and recurrence of MS symptoms in 70-80% of cases (Warren et aI., 1982). The mechanism involving the role of stress in MS appears to be quite complex. Because of the autoimmune nature of this disease, along with evidence that stressful events exacerbate symptoms, it is prudent to begin to investigate how stress might effect the course of MS by studying the effect of restraint-stress on the neuropathogenesis of Theiler's virus-infection.

▼ Recent data generated from adult male and female rats indicates that lepton is capable of stimulating luteinizing hormone (LH) secretion via a hypothalamic action. Consequently, we hypothesized that this peptide may similarly play a role in controlling LH secretion during late juvenile and peripubertal development, hence contributing to hypothalamic-pituitary function during sexual maturation. Therefore, this study was conducted to determine if lepton is capable of stimulating LH release during this critical time of development and, if so, to determine whether this action is due to an effect at the hypothalamic level. Results showed that lepton, when administered directly into the third ventricle (3V) of the brain, can stimulate (P<0.01) LH release in late juvenile animals at doses of 0.01-1.0[]g. A higher dose of 10[]g was ineffective in stimulating LH release. Immunoneutralization of luteinizing hormone-releasing hormone (LHRH) via 3V administration of LHRH antiserum to late juvenile animals indicated a hypothalamic site of action, since the leptin-induced LH release was blocked in the animals that received anti-tell-RH, but not in the control animals that received normal rabbit serum. Leptin did not significantly stimulate LH release from animals in first proestrus, estrus or fiestas. We also report that the serum levels of lepton increase (P<O.O5) during the late juvenile period of development, then decrease (P<0.05) once the animal enters the peripubertal period. Collectively, our results show that leptin is capable of acting centrally to stimulate LH release during late juvenile development, a time when serum lepton levels were shown to be elevated. Also, our results suggest that since lepton did not simulate LH release during the peripubertal phase of development, the peptide likely plays an early role in the pubertal process.

▼ Polycyclic aromatic hydrocarbons (PAHs) and halogenated aromatic hydrocarbons (HAHs) are ubiquitous in the environment. Some congeners produce extreme toxicity in laboratory Animal studies. While much attention has been given to the carcinogenicity, little work has been done in neurotoxicology. Therefore, the focus of this thesis was to analyze neurotoxicity by these measurements of cytotoxicity in neuronal and goal 11 lines. Amino acid incorporation into proteins, total protein, trypan blue dye exclusion and total cell count were measured as indicators of cytotoxicity. In addition acetycholinesterase (ACM) activity was measured as a direct indicator of neurotoxicity. Cells were exposed to three model PAHs, benzo(a)pyrene (BAP), cosine, and anthracene, and one model HAH, pentachlorophenol (PCP). Neurotoxicity of individual PAHs and PCP was compared with mixtures of PAHs and PCP. In this thesis SY5Y and C6 cell lines were used. The test concentrations of each PAH and PCP were 0.03, 0.3, 3. 30 []M. BAP showed the highest mycotoxic of the compounds tested. At a dose of 3 []M or 30 []M, BAP produced a significant mycotoxic response in SY5Y cells. SY5Y cells teated with cosine, anthracene, and PCP showed no significant effects compared to controls. C6 cells appeared to be less sensitive to the cytotoxicity then SY5Y cells. This finding may reject the lower level of P450 activity compared with SY5Y cells. S9 liver extras, which possesses high P450 activity, was used to enhance metabolism of PAHs. In most cases, the individual PAHs were inactive in C6 cells without agitation, while cytotoxicity was increased following S9 metabolism. In the present study, the rank order of neurotoxicity was BAP > chrysene > anthracene. In SY5Y cells, mixtures of BAP and chrysene or BAP and PCP exhibited the same degree of cytotoxicity as did the individual chemicals. However, in C6 cells the mixture of 3 []M BAP and 3 []M chrysene induced a more mycotoxic response than at same concentration of individual compounds. PCP at 3[]M alone significantly inhibited AChE activity in SY5Y cells, but BAP and chrysene had no effect. Furthermore, binary mixtures of PCP with mipafox together produced a significant increase in inhibition of AChE. These data suggest that co- exposure to PCP and organophosphates may result in a chemical interaction that increases the relative toxic response.

▼ Previously, it has been shown that insulin-like growth factor-1 (IGF-1) of peripheral origin acts centrally to stimulate the secretion of luteinizing hormone releasing hormone (LHRH) during the onset of puberty. This release of LHRH acts upon the pituitary gland to stimulate the release of follicle stimulating hormone (FSH) and luteinizing hormone (LH), which increases estradiol (E₂) production by granulosa cells in the ovary. It has also been shown that IGF-1 has a facilitative effect on the ability of FSH to stimulate the production of E₂ by ovaries in the first proestrous phase of peripubertal development. However, whether or not this intraovarian effect of IGF-1 occurs prior to first proestrous and thus, has an earlier action to augment E₂ secretion during the late juvenile phase of the pubertal process in not known. This study was conducted to identify the role of serum IGF-1 at the ovarian level during the developmental stages that precede first ovulation and puberty. Results showed that, when administered to granulosa cells collected from rats in the late juvenile stage of puberty, IGF-1 did not show a facilitative effect on the ability of FSH to stimulate E₂ production. However, IGF-1 did facilitate FSH-induced E₂ production (p<0.01) in granulosa cells collected from rats in the first proestrous stage. These results suggest that IGF-1 plays an important role in the facilitation of E₂ production leading to first ovulation and puberty, but only after the ovary has developed into the proestrous phase of follicular development.

▼ The number of peripheral segmental branches of the cervical and thoracic sympathetic
chains are more variable and larger than assumed by textbooks and literature (Groen et al.,
1987). This investigation aims to clarify and update the variable patterns of the cervical
sympathetic chain, the incidence of fused thoracic ganglia and the contributions of the
cervical and thoracic sympathetic chain to the cardiac plexus. The study involved the macro
and micro-dissection of 89 cadaveric sides (foetal, 60 and adult, 29).
The gross
anatomy of the cervical sympathetic chain and variations is documented. This
study confirms previous reports that the number of ganglia in the cervical region ranged
from 2 (absent MCG) to four (double MCG) ganglia. A double MCG was found in 25.9%.
This study reports the higher incidence of the normal/typical MCG (as per textbook
definition) i.e. Type II MCG (46.6%) than the Type I MCG (27.6%) and Type III (32.8%).
The number of thoracic ganglia in this study is 8-11. Fusion of ganglia was found to be
more common in the lower thoracic chain than in the upper thoracic chain. This study
reports the origin of cardiac rami from the thoracic sympathetic chain up to the
interganglionic segment between T5 and T6 ganglia. The incidence if TCR5 was 60.4%. In
15/58 sides (25.9 %) TCR5 arose from the interganglionic segment of the chain, either above
or below the ganglion.
An accurate knowledge of the
anatomy of the sympathetic nervous system and the adjacent
structures is, inescapably a definite asset to the procedures used in interrupting the neural
mechanism (Jamieson et al.) 1952). Successful sympathetic denervation of the heart, a
field often beset with failure, is dependant on adequate morphological knowledge. It is
hoped that this study using human foetuses as well as adult cadaveric specimens will draw
the attention to important variations that are relevant to the surgeon.
The intricate anatomical relations presented in this study attest the complex
anatomy of the
sympathetic nervous system.

▼ Sex identification is a crucial step in the
identification process of unknown human remains, and is mandated by
law and complies with social norms. This task becomes increasingly
difficult with remains that have badly decomposed, or have been
distorted by any natural, or man-made disasters. Thus, methods of
identification must be established for when incomplete, or damaged
remains are found. The goal of this study was to apply previously
established methods of sex estimation utilizing the sinus’ to test
their accuracy on a new sample. A retrospective study was performed
on previously acquired CT scans within the IBRC database. The study
was designed to measure volume of the frontal and maxillary sinus,
as well as the medial-lateral, superior-inferior, and
anterior-posterior dimensions of the maxillary sinus, in an attempt
to replicate two previously established methods of sex
identification in an effort to identify a preferential sinus for
sex identification. 57 subjects (30 male, 27 female) were
identified and their CT scans were used to obtain measurements
utilizing Osirix Software. Intraobserver error was first quantified
within the current study. A statistically significant difference
(p<0.0001) was found between frontal sinus volume when measured
by the same observer, which suggests measurement error, and a need
for cautionary interpretation or application of results. A
nonsignificant statistical difference (p=0.195) was found between
the male and female sample frontal sinus volumes, which determined
this parameter to be unfit for use in sex determination due to the
lack of sexual dimorphism. This was further supported with the
attempted replication of previously established frontal sinus
formulas by Michel et al. (2015) which yielded a considerably low
overall accuracy rate of 59.6%.All maxillary sinus parameters were
determined to have nonsignificant statistical differences (p >
0.05) between the right and left, suggesting that utilizing both
sides for future studies may not be necessary. Four measurements
were used to determine if sexual dimorphism exists in the maxillary
sinus with varying results: superior-inferior linear length (p =
0.003), medial-lateral linear length (p = 0.0.048),
anterior-posterior linear length (p = 0.047), and volume (p =
0.069). Despite three of the parameters indicating statistical
significance, only the superior-inferior dimension between the male
and female samples shows practical relevance. The overall weak
relationships between sexes indicate a general lack of sexual
dimorphism of parameters used in the previously established
maxillary sinus formulae developed by Rai et al. (2016).
Furthermore, these formulas resulted in variable sex identification
accuracy, with the best results obtained using the formula for the
right maxillary sinus only. This produced sex prediction with an
accuracy rate of only 60.00% within the male sample, and 62.96% in
the female sample. This study determined that the right maxillary
sinus formula provided the best accuracy results within the given…

▼ The Branchiura is a group of ectoparasitic crustaceans which infect mostly fishes. The subclass contains four genera including Argulus, Chonopeltis, Dolops and Dipteropeltis. Despite their reputation as pests our understanding of their biology is meager. In the first part of the study the anatomy and physiology is described. The species studied include Argulus japonicus, Dolops ranarum and Chonopeltis australis. Live specimens of A. japonicus, D. ranarum and Chonopeltis australis were collected, fixed in Todd's fixative and processed for transmission electron microscopy. The results gleaned from A. japonicus and D. ranarum indicated that the ultrastructure and physiology of the cells were similar to the digestive epithelia of free-living copepods. The anterior midgut consists of Resorptive cells (R cells) and the enteral diverticula consist of two cell types including R and Fibril cells (F). The R cells contain lipid droplets and F cells contain rough endoplasmic reticulum indicating that the absorption of nutrients and digestion occurs in the anterior midgut and enteral diverticula. The lipid droplets in both species are large in size and number. Blister cells/B cells and R' (apostrophe) cells occur in the posterior midgut and are involved in the processing of digestive waste. The results from C. australis were different from A. japonicus and D. ranarum and reveal the possible presence of F/R cells with multiple functions of both absorption and enzyme secretion. The cells contain few lipid droplets and instead contain many hexagonal-shaped crystalline structures that are interpreted to be proteinaceous. The differences in diet are thought to be influenced by morphological differences in the feeding appendages. The second part of the study involved the supraoesophageal ganglion or brain of C. australis. This genus is unique among the Crustacea since the antennules are absent. This trait poses implications regarding the brain morphology since particular parts of the brain impart nerves that innervate certain appendages in arthropods. Specifically the deutocerebrum or midbrain innervates the antennules. A study was conducted to discover whether the antennular nerves were absent. Specimens of C. australis were fixed in AFA, sectioned and stained with Heidenhain's AZAN. Results showed that the antennular nerves were absent and the deutocerebrum was smaller in comparison to the other brain segments indicating degeneration. Moreover, C. australis possesses a reduced number of sensory sensilla on its external surface compared to related genera. The loss of antennules does not affect its sensory capabilities in host searching. However, the reduced numbers of sensilla and its feeble swimming capabilities are more likely to reduce its efficiency in host searching.

▼ In standard anatomical textbooks, the formation of the cervical plexus is well defined;
however the accurate differentiation into superficial and deep plexuses, their emerging
patterns, and gross anatomical relations are not documented as expansively.
In order to obtain detailed anatomical knowledge of the superficial and deep cervical
plexuses, the investigation aimed to clarify the
anatomy and variations of these plexuses,
define possible anatomical landmarks, and record the relationship of the external jugular
vein and muscles of the posterior triangle of neck to the branches of the superficial
cervical plexus, and the relationship of the common carotid artery, internal jugular vein,
sympathetic chain, cervical verterbrae, and vertebral artery to the deep cervical plexus.
The studies utilized the gross anatomical dissection, morphological and statistical
analyses of forty fetal and fifteen adult cadaveric, formalinized specimens. The branches
of the superficial cervical plexus emerged from the posterior border of the
sternocleidomastoid muscle at the great auricular point (situated in the middle third of the
muscle) and was described as ascending (lesser occipital, great auricular, transverse
cervical nerves) and descending (supraclavicular nerves). Further, these branches were
recorded according to their branching patterns, relations to the external jugular vein and
variations. The branching patterns are described as single, duplicate and triplicate. The
external jugular vein was constantly located inferior to the great auricular nerve, superior
to the transverse cervical nerve and intertwined with the branches of the supraclavicular
nerves. Variations of the branches of the superficial cervical plexus were observed only
in fetuses and classified according to their course, branching patterns and
communications. The emerging point of the branches of the superficial cervical plexus
on the sternocleidomastoid muscle, were determined according to the seven types of
“emerging pattern” classification by Kim et al., (2002).
In order to record the deep cervical plexus, the sternocleidomastoid muscle was reflected
with the following observation: the ventral rami of the second and third cervical nerves
emerged between the scalenus anterior and scalenus medius muscles, and the third and
fourth cervical nerves was located at the lateral edge of scalenus medius muscle.
The deep cervical plexus was described as communicating, muscular, ansa cervicalis, and
phrenic nerves. The superior cervical ganglion constantly communicated with the ventral
rami of the cervical nerves; and the hypoglossal communicated with the superior root of
the ansa cervicalis. The muscular branches were observed to the scalenus anterior and
scalenus medius muscles with an anomalous branch to the sternocleidomastoid muscle.
The ansa cervicalis demonstrated a degree of variation with regard to its origin, course
and formation of the loops. The phrenic nerve arose from the ventral rami of the third,
fourth and fifth cervical nerves and descended on the…

▼ A human anatomy teacher-scholar is a scholar whose area of expertise includes content knowledge of the anatomical sciences (gross anatomy, histology, embryology, and/or neuroanatomy) and whose research interests and focus are centered in medical educational outcomes. The projects described in this dissertation represent endeavors I engaged in to become a human anatomy teacher-scholar. These projects included: 1) prospectively testing a hypothesis, and performing outcomes assessment in a field for which little data (theory) exist (dissection guide educational research project), 2) creating innovative course content that bridged disciplines (cadaver autopsy project), and 3) composing original teaching material for a specific audience (human anatomy laboratory manual). The training of a human anatomy teacher-scholar emphasizes knowledge acquisition in both the basic sciences (particularly gross anatomy) and in educational outcomes research methodology and theory. Therefore, human anatomy teacher-scholars are positioned to create innovative course content and materials and assess the innovations to guide future efforts. These are important skills for faculty members involved in the education of medical students in the U.S. as the medical education system in the U.S. continues to evolve.

▼ This thesis concludes with an analog model which has limitations but provides a solution to the control of cardiac output. This solution is not unique and as a model is used to predict the response to different types of stimulation, changes, will be made. However, a basic model has been presented based on the just described experiments which show that peripheral resistance is a very important factor in controlling cardiac output, both by its effect on the baroreceptor reflex and its direct mechanical effect on stroke volume. At this stage of experimentation the most important role of the model has been to explicitly give numerical values to parameters of the system but to give insight into the type or research that must be carried out to fully describe this control system as well as insight into the possible nature of relationships not yet known.

▼ Tooth impaction is a pathological condition in which a tooth is completely or partially unerupted and positioned against another tooth, bone or soft tissue, thus preventing further eruption. Many theories have been proposed to explain the prevalence of impacted third molars. These theories discuss relationship of jaw size to tooth size which is suggested to result from difference in genetics and dietary habits, as the latter differs from one region to another. The aim of this study is to investigate the prevalence of an impacted third molar tooth on a mixed population in the Greater Durban Metropolitan area. The third molar was classified using Winter’s and Pell and Gregory’s classification schemes. Various morphometric parameters of the mandible were measured and assessed in 320 digital panoramic radiographs (n=640). Each parameter recorded was statistically analyzed, using SPSS, to determine if a relationship existed between the aforementioned parameters and sex and age of each individual. 77.9% of cases presented with at least one impacted third molar, with the most prevalent type of impaction being mesio-angulation in the mandible and vertical angulation in the maxilla. In respect to the level of impaction, class IIB and class A was most frequent in the mandible and maxilla, respectively. For correlation with sex, only the length of the mandibular ramus was statistically significant (p-value=0.000). No statistically significant relationship was found between each morphometric parameter and age. However, these results correlated with previous studies indicating that impacted third molars are most prevalent in individuals between 20-25 years. In addition, all morphometric parameters in this study differed from that recorded in previous studies conducted in the Northern Hemisphere. The findings of this study may assist maxillofacial surgeons, dentists, anatomists, anthropologist and forensic investigators.

▼ Chondrichthyans (sharks, rays, skates, and chimaeras) are a diverse taxonomic clade inhabiting bodies of water all over the world. As a lineage, chondrichthyans split from the other jawed vertebrates 450 million years ago, the most basal split in the gnathostome vertebrate tree. Although they have been studied for centuries, knowledge about these animals lags behind that of many other vertebrate groups. This work uses Computed Tomography (CT) to explore morphological variation across phylogenetically diverse species of chondrichthyans. CT imaging is a nondestructive method for viewing internal structures of extant and fossilized specimens. After CT scan data acquisition, reconstruction software was used to manually segment the skeletal anatomical into constituent structures, creating 3-Dimensional representations of the structures. In most groups of vertebrate organisms, skeletal structures are made of calcified bone which has high radiopacity, leading to greater contrast between the skeleton and soft tissues. Chondrichthyans, by comparison, have skeletons composed of cartilage which is much less radiopaque than bone, resulting in lower contrast with surrounding tissues. Variations in the skeletal structures are discussed along with notes on calcification within the chondrichthyan orders. This work is presented as a summary of the variation observed in the skeletal anatomy, building upon previous works in chondrichthyan anatomy, expanding the current state of knowledge of the diversity in chondrichthyan fish skeletons. This project is part of a collaborative effort to develop a phylogenetic tree of life for modern chondrichthyans.

▼ Introduction
Hepatotoxicity has remained a serious complication limiting the efficacy of highly active
antiretroviral therapy (HAART) regimen. While this challenge continues to exist, finding possible
solutions continues to attract scientific solutions.
Materials and Method:
Sixty- three adult male Sprague-Dawley rats were used for the study and were divided into 9 groups
(A-I). Group A received HAART cocktail (Lamivudine, Stavudine & Nevirapine), Group B
received HAART and H. hemerocallidea extract (100 mg/kgbw), Group C received HAART and H.
hemerocallidea extract (200 mg/kgbw), Group D received HAART and vitamin C, Group E
received HAART and vitamin E, Group F received HAART, vitamin C and vitamin E, Group G
received H. hemerocallidea extract (100 mg/kgbw), Group H received H. hemerocallidea extract
(200 mg/kgbw), and Group I received water as placebo. The experiment lasted for 56 days after
which, the animals were sacrificed, the liver were harvested and prepared for histological
examination and blood samples were collected through cardiac puncture and centrifuged to get the
serum for biochemical assessment.
Results
While no mortality was reported, animals treated with adjuvant HAART and AP recorded least
%body weight gain. Significant derangements in serum lipid profiles were exacerbated by treatment
of with AP as LDL (increased p<0.03), TG (increased p<0.03) with no change in total cholesterol
levels. Adjuvant AP with HAART recorded reduced LDL (p<0.05 and 0.03), increased HDL
(p<0.05) and TG (p<0.05 and 0.001). Markers of liver injury assayed showed significant increase
(p<0.003, 0.001) in AST in AP alone as well as HAART+ vitamins C and E groups respectively.
Adjuvant HAART and AP and vitamins C and E also caused significant declines in ALT and ALP
levels. Serum GGT were not markedly altered. Histopathological derangements ranged from severe
hepatocellular distortions, necrosis and massive fibrosis following co-treatment of HAART with
vitamins C and E as well as HAART alone.
Conclusion
The results warrant caution on the adjuvant use of H. hemerocallidea with HAART by PLWHAs as
implications for hepatocellular injuries are suspect with untoward cardio metabolic changes. More
vigilant monitoring of patients at risk of antiretroviral toxicity is necessary and may prove helpful.
