Bax is a Bcl-2 family member that promotes apoptosis and counters the protective effect of Bcl-2. Bax is a downstream effector of p53-induced apoptosis and is transcriptionally regulated by p53. Moreover, the introduction of Bax deficiency accelerates the onset of tumors in transgenic mice expressing truncated large T antigen. These results implicate Bax as… (More)
Laboratory criteria used for presumptive diagnosis of enteroviral meningitis were evaluated as predictors of cerebrospinal fluid (CSF) infection. Records were retrospectively analysed of infants under four months of age admitted to hospital between 1977 and 1987 with viral CSF cultures: those with enteroviruses isolated from CSF (group 1) were compared with… (More)
BACKGROUND Evidence concerning the concentrations of volatile anesthetics that prevent learning and recall is limited. Epinephrine is believed to enable learning during anesthesia. We investigated the effects of isoflurane and its interaction with epinephrine on learning and subsequent retention of the rabbit's classically conditioned nictitating membrane… (More)
