Mast cells modulate the inflammatory process in endotoxin-induced uveitis
(2011-05-30)
Purpose: To investigate the role of mast cells and annexin-A1 (Anxa1) in endotoxin-induced uveitis (EIU). Methods: EIU was induced by injection of lipopolysaccharide (LPS) into the paws of rats, which were then sacrificed ...
The thrombocyte aggregation process in the turtle Phrynopys hilarii (Chelonia). An ultrastructural study
(2002-07-01)
This study investigates the thrombocyte aggregation process in the South American fresh water turtle (Phrynopys hilarii) using electron microscopy. Blood was taken from surgically exposed lateral neck vessels often turtles ...
Kinetics of spermatogenesis in the Mongolian gerbil (Meriones unguiculatus)
(2002-05-06)
The Mongolian gerbil (Meriones unguiculatus) is a small rodent native to the arid regions of Mongolia and Northeastern China. The present study provides descriptions of both the cellular associations of the seminiferous-epithelium ...
Anticancer effects of geopropolis produced by stingless bees on canine osteosarcoma cells in vitro
(2013-05-13)
Geopropolis is produced by indigenous stingless bees from the resinous material of plants, adding soil or clay. Its biological properties have not been investigated, such as propolis, and herein its cytotoxic action on ...

(2006-05-01)
Purpose: To analyze, in vitro, the effects of acetylsalicylic acid (aspirin) and acetic acid solutions on VX2 carcinoma cells in suspension and to examine the correlation between these effects and neoplastic cell death. ...
Gestational protein restriction induces CA3 dendritic atrophy in dorsal hippocampal neurons but does not alter learning and memory performance in adult offspring
(2013-05-01)
Studies have demonstrated that nutrient deficiency during pregnancy or in early postnatal life results in structural abnormalities in the offspring hippocampus and in cognitive impairment. In an attempt to analyze whether ...
The fine structure of the swine sweat gland. II. The coiled ducts
(1985-12-01)
The duct of the swine sweat gland crosses the dermis and epidermis in sequence. The cells of the dermic segment seem to be related with cellular secretion and absorption. In the epidermic segment of the duct the whole ...
The role of mitochondria and biotransformation in abamectin-induced cytotoxicity in isolated rat hepatocytes
(2013-03-01)
Abamectin (ABA), which belongs to the family of avermectins, is used as a parasiticide; however, ABA poisoning can impair liver function. In a previous study using isolated rat liver mitochondria, we observed that ABA ...
