O objetivo deste trabalho foi identificar espécies de Staphylococcus (n=100) isoladas de mastite em rebanhos bovinos do Estado de Minas Gerais. Para esta finalidade foram utilizadas reações de PCR empregando oligonucleotídeos iniciadores descritos anteriormente para amplificar genes específicos de S. aureus (femA), S. intermedius (rDNA 16S) e S. hyicus (rDNA 16S-23S) e o sequenciamento do rDNA 16S. De acordo co...
Clin Sci (Lond). 2002 Nov;103(5):475-85 ; The accumulation of toxic bile salts within the hepatocyte plays a key role in organ injury during liver disease. Deoxycholate (DC) and glycochenodeoxycholate (GCDC) induce apoptosis in vitro and in vivo, perhaps through direct perturbation of mitochondrial membrane structure and function. In contrast, ursodeoxycholate (UDC) and its taurine-conjugated form (TUDC) appea...
Background/Aims: Unconjugated bilirubin (UCB) impairs crucial aspects of cell function and induces apoptosis in primary cultured neurones. While mechanisms of cytotoxicity begin to unfold, mitochondria appear as potential primary targets. Methods: We used electron paramagnetic resonance spectroscopy analysis of isolated rat mitochondria to test the hypothesis that UCB physically interacts with mitochondria to i...
