N6-Cyclohexyl[3H]adenosine ([3H]CHA) and 1,3-diethyl-8-[3H]phenylxanthine ([3H]DPX) to bind to adenosine receptors in brain membranes. The agonist [3H]CHA has high affinity in both bovine and guinea pig brain (Kd, 0.7 nM and 6 nM, respectively). [3H]CHA binding kinetics are slow (dissociation t1/2;60 min); binding is much higher at 25 degrees C than at 0 degrees C and is inhibited by guanine nu...

background: toxoplasmosis is a worldwide spread disease. the present study examined the prevalence of toxoplasma gondii infection among animals of ediblemeat (cattle and sheep) in chaharmahal va bakhtiari province (southwest of iran) in 2012. furthermore, we attempted for the first time to identify this parasite from the meat products in the province. methods: the tongue, brain, femur muscle an...

Infected urachal cysts are a rare clinical manifestation in adults. We present the case of a female patient with an infected urachal cyst, discuss the embryology, clinical presentation, diagnostics and the therapeutic procedure and make a comparison with the literature.

QuEChERS (quick, easy, cheap, effective, rugged, and safe) sample preparation methods have been developed to help monitor pesticides in a range of food samples. These methods require many manual steps, such as shaking, centrifugation, and dispersive SPE cleanup, making it a quite labor-intensive process. There is a need for automating parts of QuEChERS extraction in order to improve laboratory ...

Convergent and divergent validity are critically important in developing psychological measures that reveal interpretable deficits in disordered populations. This article reports on 2 studies that evaluated the validity of context processing measures. In Experiment 1, a confirmatory factor analysis of data from 481 healthy adults established the convergent validity of 2 context processing measu...

The WWW servers at http://www.icgeb.org/protein/ are dedicated to the analysis of protein 3D structures submitted by the users as the Protein Data Bank (PDB) files. CX computes an atomic protrusion index that makes it possible to highlight the protruding atoms within a protein 3D structure. DPX calculates a depth index for the buried atoms and makes it possible to analyze the distribution of bu...

Background and Aims: Hepatitis B virus (HBV) infects the liver and causes acute and chronic hepatitis, hepatocellular carcinoma and cirrhosis. HBV has been divided to eight genotypes (A–H) and subgenotypes of A, B, C and F. For the first time, we determined HBV genotypes in infected samples by INNO-LiPA method in Yazd, central province of Iran. Materials and Methods: This study was performed...
