The development of animal infection models and antifungal efficacy assays against clinical isolates of Trichosporon asahii, T. asteroides and T. inkin.

The present study developed Galleria mellonella and murine infection models for the study of Trichosporon infections. The utility of the developed animal models was demonstrated through the assessment of virulence and antifungal efficacy for 7 clinical isolates of Trichosporon asahii, T. asteroides and T.

Clinical, demographic and epidemiological characteristics of patients with hepatitis B followed at a university hospital in southeastern Brazil: predominance of HBeAg negative cases.

Introduction: Hepatitis B is common in Brazil, although there are regional differences regarding the degree of endemicity, the most frequent forms of transmission and the presence of different evolutive stages of chronic disease. The present study aimed to determine the clinical, demographic and epidemiological characteristics of patients chronically infected with hepatitis B virus (HBV) residing in the Ribeirão Preto region, southeastern Brazil.

Methods: A total of 529 medical records of individuals with HBV monoinfection were reviewed.

Hyperbaric oxygen on the healing of ischemic colonic anastomosis--an experimental study in rats.

The aim of the present study was to evaluate the effect of hyperbaric oxygen therapy (HBO2) on the healing process of ischemic colonic anastomoses in rats. Forty Wistar rats were divided into four groups: control (Group I), control and HBO2 (Group II), ischemia (Group III), ischemia and HBO2 (Group IV). Ischemia was achieved by clamping four centimeters of the colonic arcade.
