A graph theory model and its invariants are used to compare previously published renal glomerular networks of six adult rats, one adult uremic rat, and one newborn rat. Invariants calculated include order, size, cycle rank, eccentricity, root distance, planarity, and vertex degree distribution. These invariants enabled the differentiation of six normal adult glomerular microvascular networks fr...

BACKGROUND: In the present study, the submandibularsalivary gland microscopic morphology of the adult Africangiant pouched rat was investigated. This study was carried out toprovide the basic histology of this organ in the giant pouched rat,to accompany the dearth of information of its microscopicarchitecture in the available literature. This becomes of evenhigher importance when considering th...

Vitamin E (vit. E) is an antioxidant compound with different kinds including tocopherols and tocotrienols. The major sources of vit. E are vegetable and seed oils. The recommended dietary allowances vary with age, gender, and state of the person. There have been numerous experiments showing beneficial effects of vit. E on immune system, cancer, and coronary artery diseases in the elderly. Moreo...

Several evidences have indicated that many nuclei in the brain have critical role in water intake. Angiotensin II is one of the most important neurotransmitters involved in regulation of fluid homeostasis. In this study, the interaction of i.c.v. injection of captopril and histamine on water intake in adult male water-deprived rats was investigated. Rats were implanted with guide cannula aimed ...

Cell-surface proteoglycans have been implicated in cell responses to growth factors, extracellular matrix, and cell adhesion molecules. M12, one of the most abundant membrane-associated proteoglycans in the adult rat brain, is a approximately 65 kDa glycosylphosphatidylinositol-linked protein that bears heparan sulfate chains (Herndon and Lander, 1990). To assess its identity, M12 was purified ...
