#1
Pilani Nkomozepi, Nkosi Xhakaza, Elaine Swanepoel
Nerve entrapment syndromes occur because of anatomic constraints at specific locations in both upper and lower limbs. Anatomical locations prone to nerve entrapment syndromes include sites where a nerve courses through fibro-osseous or fibromuscular tunnels or penetrates a muscle. The median nerve (MN) can be entrapped by the ligament of Struthers; thickened biceps aponeurosis; between the superficial and deep heads of the pronator teres muscle and by a thickened proximal edge of flexor digitorum superficialis muscle...

BACKGROUND: Among authors studying morphological determinants of the Obstructive Sleep Apnoea (OSA) controversies exist on the location of the narrowest area within the pharynx critical for development of obstruction. Those disagreements primarily revolve around differences between obese and nonobese OSA patients. Determination whether the location and size of the narrowest area within the pharynx differentiates the obese and nonobese OSA patients. MATERIALS AND METHODS: A population of 55 subjects was investigated after being diagnosed with OSA in the Polysomnography Laboratory of the Department and Clinic of Otolaryngology in the Medical University of Warsaw...

In this study, morphological characteristics of the canary tongue were examined macroscopically and histologically besides using scanning electron microscopy (SEM). Furthermore, histochemical features of the lingual salivary glands of the canary were also examined. The results suggest that the tongue of the canary has an equilateral quadrangle shape is sloped towards the apex on its dorsal surface; where its sides are bounded by tall epithelial extensions. Additionally, histological examination showed that salivary glands were only present on the body of the tongue and there were no taste buds...

The internal jugular vein (IJV) is an important vascular structure for oncologists and radiologists and is also a frequently used central venous route. The variations in the pattern of its course, and knowledge of its variations, are important. During the anatomical dissection of a 70-year-old male cadaver, fenestration involving a short segment (2.5 cm) of the right IJV in the superior part of the carotid triangle and a large dilatation (phlebectasia) of the IJV, involving its nonfenestrated segment were found - a case that has not previously been reported...

A rare combination of variations in the arterial supply of the liver and gallbladder was encountered in a male cadaver: The simultaneous occurrence of an accessory left hepatic artery and an accessory right hepatic artery from which double cystic arteries arose (one of which was low-lying). This combination has not yet been reported. The accessory left hepatic artery originated from the left gastric artery. The accessory right hepatic artery originated from the superior mesenteric artery. Such arterial variations are caused by differences in embryological development...

Acellular scaffolds are used for the surgical repair of soft tissue injury forming a biological basis for cell remodeling. Previously tissue-dependent effects sodium-dodecyl-sulfate (SDS) have been determined on the extracellular matrix (ECM) of different tissue types. This short report aims at extending these findings onto a tissue-layer level with focus on the ECM. Porcine ureters, esophagi and skin underwent acellularization using SDS, whereas control samples remained in a native condition. The samples were investigated histologically and ultrastructurally electron microscopy...

Revascularization is crucial to liver regeneration after liver injury, but the process remains unclear. This study investigated changes in the levels and distribution of lymphatic vessel endothelial hyaluronan receptor 1 (LYVE1) and prospero homeobox protein 1 (PROX1) in liver tissue sections after partial hepatectomy in mice. Mice were subjected to partial hepatectomy. Control animals were sham-operated. From days 1 through 8, the remaining liver tissues were collected from 8 animals each day. Histology showed that after partial hepatectomy, the remaining liver tissue samples underwent initial degeneration and then hepatocyte proliferation and regeneration...
