Knee joint development and its morphogenetic events have been studied in human, chicken and other animal models and differences have been found in the pattern of the knee joint morphogenesis among the studied species. According to the small number of studies which have focused on the chronology of knee morphogenesis, a "morphogenetic timely pattern" is hard to suggest. Quail is an animal model for which there is no information about knee joint morphogenesis. This study was planned to define the time table of the knee joint structures formation in this bird...

INTRODUCTION: There have been no previous reports on hepatic surface grooves in an Afro-Caribbean population. This information is important to optimize radiology and hepatobiliary surgical services in the region. METHODS: Two investigators independently observed 69 cadaveric dissections performed over five years at the University of the West Indies. Variations in surface anatomy were described. RESULTS: In this Caribbean population the majority of patients had conventional hepatic surface anatomy (88%)...

Sarcoglycan subcomplex is a transmembrane glycoprotein system which connects extracellular matrix to cytoskeleton. Although this complex has been found in several non-muscular tissues, no data exist about a sarcoglycan subcomplex in brain. Only the presence of ε-sarcoglycan in brain has been described in detail because its mutation determines Myoclonus Dystonia Syndrome. Also ζ-, β- and δ-sarcoglycans have been found in brain but only at mRNA level and their distribution in brain is still unknown. Here, we have searched for the expression of all sarcoglycans in specific brain regions of rat as hippocampus, cerebral and cerebellar cortex...

The seasonal thermal cycle and correlated variations in photoperiod exert antithetical influences on the proliferation of the reserve brain stem cells, which are mostly ependymal and subependymal, of adult earth-dwelling heterothermic vertebrates upon deprivation of an encephalic area. Also, an induced sudden, transient thermal stress preceding surgical cerebral maiming increases or depresses the proliferation of these stand-by cells, depending on the season. In particular, the concomitance of spring temperature and photoperiod with a cold stimulus increases proliferation...

Holoprosencephaly is a brain malformation that develops as a result of a defect in development of prosencephalon during early gestation. Holoprosencephaly can be diagnosed with prenatal ultrasonography and magnetic resonance imaging. We report herein a case with cyclopia and holoprosencephaly detected by prenatal ultrasonography.

It has been shown previously that in adult Rana esculenta, caught in nature, cold-shocked and brain-injured, encephalic cell proliferation is increased when capture and experiment occurred in spring and depressed when they occurred in autumn. Upon exclusive thermal stress cell proliferation appeared weak in spring and intense in autumn. The present study has investigated cold-shocked, but otherwise uninjured Rana bergeri to assess the impact of autumnal environment on encephalic cell proliferation. Lowering temperature--natural or experimental--seemed to exert a mild stimulation on the proliferative activity only in the forebrain...

Recurrent laryngeal nerve palsy is a common post-operative complication of many head and neck surgeries. Theoretically, the best treatment to restore partial function to a damaged recurrent laryngeal nerve would be reinnervation of the posterior cricoarytenoid muscle via anastomosis of the recurrent laryngeal and phrenic nerves. The pig is an excellent model of human laryngeal anatomy and physiology but a more thorough knowledge of porcine laryngeal anatomy is necessary before the pig can be used to improve existing surgical strategies, and develop new ones...

Internal thoracic and inferior thyroid arteries mainly supply the thymus. However, very few studies have been reported on the arterial variations of the thymus. The first author, a cardiac surgeon, happened upon a thymic artery arising from either proximal aortic arch or distal ascending aorta in a few cases during routine cardiac surgery in infants and neonates. Hence a study on the prevalence of the variant thymic artery during open heart surgery was contemplated, as knowledge of its presence could avoid its injury during surgical and diagnostic procedures of the region...

Dimitrios Alexandrou Mavrokordatos was the first regular professor of Anatomy and Physiology of the Hellenic "Othonian" University of Athens. He had completed his studies in Germany and thus he had been chosen to stimulate the empirical physicians of Greece to awaken. He died young, but his passion was so great that he had published a masterpiece in the new Greece, "On the anatomy of the human body", and left his fortune for his pupils, even though they had rebelled against him sometime before his death. With his teaching and book he established a kind of Greek "nomina anatomica" which formed the basis for medicine in the newly born country...

Cadaver dissection remains a cornerstone in the study of anatomical sciences by medical students. However, this activity can cause emotions that may affect learning outcomes. This study, which involved medical students of various cultural backgrounds, assessed their responses to dissection. Medicine I year students (n = 100) at Oakland University William Beaumont School of Medicine were invited to complete a questionnaire after the first week of dissection, and again at the end of the course. The questionnaire asked for demographics, and assessed the students' appraisal of their dissection experience, cultural influences, coping activities and learning outcomes...

The human umbilical vein, as a readily available stem cell source, is a good alternative to harvest mesenchymal stem cells. Human umbilical cord vein mesenchymal stem cells have recently been isolated and have demonstrated the ability to differentiate into various cell types such as fat, bone, cartilage and neuronal cells. In this study, we have investigated whether human umbilical cord vein mesenchymal stem cells are also able to differentiate into hepatocyte-like cells. Hepatic differentiation was performed with a 2-step protocol and the use of hepatocyte growth factor and oncostatin M for cell culture...

The Indian mongoose (Herpestes javanicus) is native to parts of Asia, Iran. The purpose of this study was to describe the gross anatomy of the cartilage and histology of the superficial gland of the third eyelid of two adult mongooses. The animals, in terminal stages of disease and near death due to aging or unknown reasons, were referred from Park Zoo (Shiraz, Iran) to our center. By using a modified maceration technique, the morphological characteristics of the cartilage were examined. For histological examinations of the superficial gland of the third eyelid, the samples were stained with haematoxylin and eosin...

Osteoarthritis focuses principally on the degeneration of articular cartilage as a primary cause of the disease. The pathophysiological process of osteoarthritis is characterized by alteration of chondrocytes and the increased bone formation by sub-chondral osteoblasts. Infiltration of macrophages and perivascular T and B lymphocytes is observed, and these infiltrates have been demonstrated in both early and advanced disease. The morphological and phenotypic characteristics of osteocytic cells attached to the normal and the osteoarthritic matrix differ from each other, suggesting that specific signalling pathways arise or are altered between matrix and cells...

REVIEW
Kaissar Yammine
The flexor digitorum brevis muscle, and in particular its fourth slip, has a significant clinical and surgical importance in medical practice. However, as for the majority of tendons destined to the little toe, the fourth slip is undergoing a phylogenetic degeneration. The aim of this meta-analysis is to conduct an evidence synthesis on the prevalence of FDB-5 and its variants in humans. Twenty-two studies met pre-defined inclusion criteria with a total of 2789 feet and 416 cadavers. Meta-analytical results of fourth slip agenesis were as follows; a) a true prevalence rate of 31...

The greater cane rats (Thryonomys swinderianus) and African giant pouched rats (Cricetomys gambianus) are among the largest rodents in Africa, undergoing domestications for meat and research purposes. The aim of this study was to explore whether there are any quantitative anatomical gastrointestinal adaptations associated with their omnivorous or herbivorous diets. In the African giant rat, the mean gastrointestinal tract length and colon width of the males were significantly higher than their females counterpart (P < 0...

Joaquín Maria Albarrán (1860-1912) is broadly known as a brilliant mind and a pioneer of modern urology, in spite of his short life. Born in Cuba and being early an orphan, he was sent to Barcelona to study Medicine. Graduate at the age of seventeen, he continued his studies in Paris, where he was trained in surgery and urology, and spent the rest of his life having an extraordinary career as urology surgeon, chief of the Urology Department in Necker Hospital and professor at Paris Faculty of Medicine. Since his first studies, he had been passionate with anatomy, histology, pathology and microbiology and embodied in his books, today considered as classics, a great amount of the special knowledge he had for these fields and the most accurate descriptions of the operative techniques for the urinary tract system...

Aretaeus of Cappadocia did not deal systematically with the study of anatomy, as it can be assumed from the thorough study of his remaining work, as well as the references to the topics and the fragments of his lost treatises. We could also extract useful information on anatomy through his analytical descriptions about the various diseases in his remaining work. A perfect example is the anatomy of the upper and inferior vena cava exposed in his work on acute diseases.

This rare case of amelia in a doe-goat was observed in Tarka local government area, Benue State, middle belt region of Nigeria. The congenital deformity consisted of complete agenesis of the affected fore limb; the defect is commonly unilaterally manifested. The present congenitally impaired goat was approximately one and a half years old, and was a second kiddling of a normal multiparous dam. The left fore limb was grossly vestigial in development, while the homologous right hoof was splayed; the hind limbs were anatomically normal...
