Microscopic evaluation of proliferative disorders in the gerbil female prostate: Evidence of aging and the influence of multiple pregnancies
(Micron, 2011-10-01) [Resenha]
The gerbil female prostate is located paraurethrally and has all the histological components of the male prostate, like secretor epithelium and fibromuscular stroma. This gland, like the prostate in males, is targeted by ...
Progesterone restores the female prostate activity in ovariectomized gerbil and may act as competitor of testosterone in intraprostatic environment
(Life Sciences, 2013-05-30) [Artigo]
Aims Little is known about the effect of progesterone on gerbil female prostate. It is known that normal oscillation in the progesterone and estradiol levels during the estrous cycle phases influence the morphophysiology ...
Physicochemical characterization of nanoparticles formed between DNA and phosphorylcholine substituted chitosans
(Journal of Colloid and Interface Science, 2009-08-01) [Artigo]
The interactions between phosphorylcholine-substituted chitosans (PC-CH) and calf-thymus DNA (ct-DNA) were investigated focusing on the effects of the charge ratio, the pH, and phosphorylcholine content on the size and ...
Subcellular localization of proteins labeled with GFP in Xanthomonas citri ssp citri: targeting the division septum
(FEMS Microbiology Letters, 2010-09-01) [Artigo]
Xanthomonas citri ssp. citri (Xac) is the causal agent of citrus canker, an economically important disease that affects citrus worldwide. To initiate the characterization of essential biological processes of Xac, we ...
Apoptosis in tongue squamous cell carcinoma and its correlation with clinically occult cervical metastasis
(Micron, 2008-10-01) [Artigo]
Squamous cell carcinoma of the tongue is one of the most common head and neck cancer. Treatment in the early stages is still controversial. This study aims to correlate the apoptosis rate of primary tongue cancer with ...
Oxidative stress markers and apoptosis in the prostate of diabetic rats and the influence of vitamin C treatment
(Journal of Cellular Biochemistry, 2012-07-01) [Artigo]
Negative consequences of diabetes on the prostate such as involution are associated with diminished testosterone, insulin deficiency, and hyperglycemia. The contributions of oxidative damage, which usually increases with ...
Anatomy of smooth muscle cells in nonmalignant and malignant human prostate tissue
(Anatomical Record-advances In Integrative Anatomy and Evolutionary Biology, 2008-09-01) [Artigo]
Differently graded areas of human prostate adenocarcinoma were examined after Masson's trichrome staining or immunohistochemistry for smooth muscle alpha-actin, type IV collagen and laminin. In addition, the ultrastructure ...
Phytoseiidae (Acari) in forest fragments in the State of São Paulo, Brazil
(Zootaxa, 2011-11-01) [Artigo]
Mites of the family Phytoseiidae have been extensively studied as biological control agents of various pests. However, knowledge of these mites in plants of forest fragments in Brazil is still incomplete. The aim of this ...
Relationship between the nucleolar cycle and chromatoid body formation in the spermatogenesis of Phrynops geoffroanus (Reptilia Testudines)
(Animal Cells and Systems, 2012-04-01) [Artigo]
The nucleolus is a distinct nuclear territory involved in the compartmentalization of nuclear functions. There is some evidence of a relationship between nuclear fragmentation during spermatogenesis and chromatoid body ...
RECK-Mediated Inhibition of Glioma Migration and Invasion
(Journal of Cellular Biochemistry, 2010-05-01) [Artigo]
RECK is an anti-tumoral gene whose activity has been associated with its inhibitory effects regulating MMP-2, MMP-9, and MT1-MMP. RECK level decreases as gliobastoma progresses, varying from less invasive grade II gliomas ...
