Introduction: The mechanisms involved in the virulence and recurrences of ocular toxoplasmosis are poorly understood. New detection methods are necessary to diagnose atypical cases and to better understand recurrences. A sensitive method to identify Toxoplasma gondii in peripheral blood of patients is necessary. Purpose: To detect the presence of T. gondii in peripheral human blood using immuno...

Hepatitis B virus (HBV) DNA is prone to mutations due to proofreading deficiencies of HBV polymerase. We have previously identified hepatocellular carcinoma (HCC) survival-associated HBV mutations in the X, precore, and core regions. In the present study, we extended our research to assess HCC survival-associated HBV mutations in the small S gene of HBV genome in 115 HCC patients including 60 p...

Nicotine-stimulated (86)Rb(+) efflux and [(3)H]cytisine binding, both of which seem to measure the nicotinic acetylcholine receptor, composed of alpha4 and beta2 subunits, were assessed in eight brain regions obtained from 14 inbred mouse strains. The potential role of a single nucleotide polymorphism (SNP) in the nicotinic receptor alpha4 subunit gene (Chrna4) on nicotinic receptor binding and...

We present the analysis of physical conditions, chemical composition and kinematic properties two bow shocks -HH529 II HH529 III- fully photoionized Herbig-Haro object HH 529 in Orion Nebula. The data were obtained with Ultraviolet Visual Echelle Spectrograph at 8.2m Very Large Telescope 20 years Hubble Space imaging. separate emission high-velocity components III from nebular one, determining ...
