Effects of diuron on toxicological and hematological parameters and lymphohematopoietic organs in a rat chemical hepatocarcinogenesis model
(Annual Review of Biomedical Sciences, 2005) [Artigo]
High laryngeal mask airway pressures resulting from nitrous oxide do not increase pharyngeal mucosal injury in dogs
(Canadian Journal of Anaesthesia-Journal Canadien D Anesthesie, 2001-09-01) [Artigo]
Purpose: During general anesthesia, nitrous oxide (N2O) diffuses rapidly into the air-filled laryngeal mask airway (LMA) cuff, increasing intracuff pressure. There is no clear correlation between LMA intracuff pressure and ...
Ultrastructural and morphometric aspects of ageing in the retinal capillaries of rats
(Journal of Submicroscopic Cytology and Pathology, 1997-04-01) [Artigo]
Age-related morphological, ultrastructural and morphometric changes in the capillaries of the superficial and deep plexuses of the rat retina were studied in animals aged from 3 to 15 months. Our results suggest that ...
End-to-end arterial anastomosis with fibrin glue in larger arteries: histology, hydroxyproline concentration and tensile strength study in carotids of rabbits
(Acta Cirúrgica Brasileira, 2002-02-01) [Artigo]
A anastomose arterial término-terminal é demorada, requer tempo prolongado de oclusão vascular e esta associada a necrose focal, infiltração leucocitária e, conseqüentemente, à fibrose e calcificação da parede arterial. A ...
Mushroom-derived preparations in the prevention of H2O2-induced oxidative damage to cellular DNA
(Teratogenesis Carcinogenesis and Mutagenesis, 2002-03-06) [Artigo]
Aqueous extracts of the sporophores of eight mushroom species were assessed for their ability to prevent H2O2-induced oxidative damage to cellular DNA using the single-cell gel electrophoresis (Comet) assay. The highest ...
Lack of chemoprevention of dietary Agaricus blazei against rat colonic aberrant crypt foci
(Human & Experimental Toxicology, 2008-06-01) [Artigo]
The mushroom Agaricus blazei (Ab) has been widely used in folk medicine to treat various diseases including cancer. No information is available on its possible protective effects on the development of colon cancer. The ...
Toxicity of dietary restriction of fat enriched diets on cardiac tissue
(Food and Chemical Toxicology, 2002-12-01) [Artigo]
The present study examines the effects of caloric restriction in cardiac tissue evaluation markers of oxidative stress. High-fat dietary restrictions can have a long-term impact on cardiac health. Dietary restriction of ...

(Biology of Reproduction, 2011-07-01) [Resumo]
Morphological aspects of rabbit masseter muscle after cervical sympathectomy
(International Journal of Experimental Pathology, 2001-08-07) [Artigo]
The objective of this paper was to study the effect of sympathetic innervation on morphological and histochemical aspects of skeletal muscle tissue. Rabbit masseter muscle was studied using histochemical and immunohistochemical ...
Farming technology, biochemistry characterization, and protective effects of culinary-medicinal mushrooms Agaricus brasiliensis S. Wasser et al. and Lentinus edodes (Berk.) Singer: Five years of research in Brazil
(International Journal of Medicinal Mushrooms, 2005-07-04) [Artigo]
The biotechnology, biochemical characterization, and protective effects of the himematsutake and shiitake mushrooms were studied for the Thematic Project, from 1998 to 2003. A new species, Agaricus Brasiliens is Wasser et ...
