The authors report a rare variation of the coeliac trunk, renal and testicular vasculature in a 27-year-old male cadaver. In the present case, the coeliac trunk and superior mesenteric artery was replaced by a modified coeliacomesenteric trunk formed by hepato-gastric and superior mesenteric arteries. Here the hepato-gastric artery or trunk contributed towards the total hepatic inflow as well as a gastro-duodenal artery. A separate right gastric artery and an additional superior pancreatico-duodenal artery was also found in addition with a retro-aortic left renal vein and a bilateral double renal arterial supply...

Cimetidine is an H2 receptor antagonist that has an antiandrogenic effect. It intervenes with the conversion of testosterone into estrogen in the Sertoli cells with accompanying testicular structural changes. In the present study, the microscopic and the ultrastructural changes induced by cimetidine and the effect of vitamin B12 as a protective agent on rat testes were studied. Immunoexpression of estrogen receptor β (ERβ) in testes was evaluated. Twenty-four adult male rats were divided into four groups: control, cimetidine-treated, vitamin B12 treated, and combined cimetidine and vitamin B12 treated...

The Chinese philosophy of Confucianism said "What I heard I forgot, what I see, I remember, what I do, I understand." During this time, most of the teaching and learning process relies on viewing and listening modalities only. As a result, much information does not last long in memory as well as the material understanding achieves became less deep. In studying anatomy science, drawing is one of effective important methods because it is an integration of ideas and knowledge of vision thereby increasing comprehension and learning motivation of college students...

A human skull was discovered at the 16th-century drainage channel of market district ruins, one of the busiest streets in the capital of Joseon kingdom. By anthropological examination, we noticed the cut mark at the right occipital part of the cranium. Judging from the wound property, it might have been caused by a strong strike using a sharp-edged weapon. As no periosteal reaction or healing signs were observed at the cut mark, he might have died shortly after the skull wound was made. We speculated that this might have been of a civilian or soldier victim who died in a battle or the decapitated head of prisoner...

The pelvis and the spine form a system balancing human skeleton. Within this system, the pelvis adapts to age-related changes in the spine. Previous studies were predominantly focused on changes of pelvic parameters in the sagittal plane. The aim of this study was to reveal age-related changes of lesser pelvic dimensions at different levels of the pelvic cavity in the sagittal and coronal planes and to explore sexual dimorphism in age-related tendencies. The computed tomography pelvimetry was performed on the three-dimensional workstation...

Sex estimation is one of the crucial procedures in the biological profile identification of human skeletal remains. Knowing sex of unknown case can lead to accurate and appropriate methods for predicting age, stature, ancestry, or even personal identification. Skull is one of the most reliable one among other skeletons and it is usually retained for both archaeological and forensic contexts. Although many morphological features and metric measurements of skull have been studied for sexing, but to the best of our knowledge is no study on maxillary suture length for sex estimation...
