The expression of aquaporins 1 and 9 in adult rat epididymis is perturbed by chronic exposure to ethanol
(2012-02-01)
Aquaporins (AQPs), notably AQP-1 and AQP-9, may contribute to reabsorption of fluid and solute across the epididymis. Ethanol is related to be a toxicant affecting directly or indirectly the epididymis and the sperm motility. ...
Expression of annexin-A1 and galectin-1 anti-inflammatory proteins and mRNA in chronic gastritis and gastric cancer
(2013-03-07)
Objective. The anti-inflammatory proteins annexin-A1 and galectin-1 have been associated with tumor progression. This scenario prompted us to investigate the relationship between the gene and protein expression of annexin-A1 ...
Structural, cytochemical, immunocytochemical and ultrastructural characterization of blood granulocytes of the roadside hawk Buteo magnirostris (Gmelin, 1788) (Avian, Falconiform)
(2003-10-01)
In the peripheral blood of the roadside hawk, Buteo magnirostris, the following types of granulocytic leucocytes were identified: heterophil, eosinophil and basophil. The heterophils presented acidophilic and spindle shaped ...
Identification of phospholipase C zeta in normospermic and teratospermic domestic cat sperm
(2013-10-15)
In mammalian species, oocyte activation is initiated by oscillations in the intracellular concentration of free calcium ([Ca2+]i), which are also essential to allow embryonic development. To date, evidence supporting the ...
Enhanced ERbeta immunoexpression and apoptosis in the germ cells of cimetidine-treated rats
(Biomed Central Ltd., 2009-11-18)
Background: Cimetidine, refereed as antiandrogenic drug, causes hormonal changes in male patients such as increased testosterone and FSH levels. In the rat testis, structural alterations in the seminiferous tubules have ...
Serotonin concentration, synthesis, cell origin, and targets in the rat caput epididymis during sexual maturation and variations associated with adult mating status: Morphological and biochemical studies
(Amer Soc Andrology, Inc, 2007-01-01)
The caput epididymis of some mammals contains large quantities of serotonin whose origin, targets, and physiological variations have been poorly studied. We combined morphological and biochemical techniques to begin ...
