Background: Rat prostate gland which is used in various investigation has considerable morphological differences with other mammals. There are few reports about its structure. So, this study was carried on for determining of histomorphological structure of rat prostate. Materials and Methods: Five healthy adult male rats with average weight 20 ± 180 g and approximately 3 - 3.5 months age were s...

Novel biomaterials for diagnostics and therapeutics of biomedical issues have been considered using science health care. Halloysite nanotubes (HNTs) are naturally occurring aluminosilicate clay. Because their unique hollow tubular structure, biodegradability, mechanical surface properties, they drawn the attention researchers to a variety applications. HNTs inorganic natural aluminosilicates th...

BACKGROUND Small caliber vascular prostheses are not clinically available because synthetic vascular prostheses lack endothelial cells which modulate platelet activation, leukocyte adhesion, thrombosis, and the regulation of vasomotor tone by the production of vasoactive substances. We developed a novel method to create scaffold-free tubular tissue from multicellular spheroids (MCS) using a "Bi...

This letter gives a credit to pioneering paper that is almost unknown scientific community. On the basis of Transmission Electron Microscopy images and X-ray Ray Diffraction patterns carbon multi-layer tubular crystals authors suggested model nanotube structure formation hypothesis on various chirality nanotubes.

The specificity of gentamicin for vitamin E deficiency-associated oxidative stresses in the renal proximal convoluted tubules is apparently related to its ability to increasingly facilitate generation of radical species in mitochondria. To determine the ways in which vitamin E manage the currently processes, we conducted a prospective study aimed to investigate the tubular preserving effect of ...

The Golgi apparatus of most plant and animal cells occurs as a system of dictyosomes (4), often dispersed throughout a large portion of the cytoplasm. Each dictyosome consists of a stack of cisternae (usually 5 or 6) and associated vesicles. The central region of a typical cisterna is sacor platelike and about a/~ /z in diameter. Tubular proliferations extend from this central structure, unit i...

introduction: the sexual maturity is a major factor of fertility and reproduction activity. since no information was availabe about microscopic developement of seminiferous tubules structure including spermatogenic cells, sertoli, pgc (primordial germ cell) and laydig cells, the present detailed study on buffalo testis was undertaken. materials and methods: the present study was made on 30 buff...

Tubular turbines are widely used in low water head and tidal power development due to their straight flow path, simple structure, wide efficient area. However, the severe vibration during actual operation greatly affects safe of tubular turbine. This study performs a numerical calculation turbine, which meets machine conditions considering free surface gravity; compares analyzes characteristics...

Objective(s) In recent years concerns have been raised regarding the incidence of male reproductive disorders from exposure to endocrine disruptors. So, chronic effects of di(2-ethylhexyl)phthalate were studied on histological and stereological structure of testis in adult Wistar rats. Materials and Methods Thirty two adult Wistar rats were randomly divided in four equal experiment groups; o...
