Background:Tenofovir is among the first-line treatments for chronic hepatitis B (CHB) virus infection. We evaluated the efficacy of Tenofovir in the treatment of Iranian adult patients with CHB. Methods: In a retrospective study, we evaluated 154 HBsAg positive patients referred to Sadoughi hospital in Yazd-Iran for treatment ...

The structural requirements for the inhibitor activity of various furan carboxanilide derivatives against succinate dehydrogenase complex (SDC) activity in mitochondria of either wild or mutant strains of Ustilago maydis were investigated with the aid of Hansch QSAR analysis. It has been found that the inhibitor activity against both types of enzymes is best related to the ??? or ??M of th...

  Objective(s): Adeno-associated virus type 2 (AAV2) vectors are widely used for both experimental and clinical gene therapy. A recent research has shown that the performance of these vectors can be greatly improved by substitution of specific surface-exposed tyrosine residues with phenylalanines. In this study, a fast and simple method is presented to generate AAV2 vector helper plasmids encod...

The objectives of the present research were to evaluate the variability induced by gamma-irradiation among a population of M8 sunflower mutant lines and to identify molecular markers associated with different seed germination traits. Experiments were carried out under well watered and water-stressed conditions using a randomized blocks design, with three replications. The studied traits consist...

Background and Aims: Q59L mutant of L-asparaginase enzyme from Escherichia coli (E. coli) has been introduced with lower side effects. This version of the enzyme might have potential applications in the treatment of leukemia patients. We utilized SHuffle T7 strain of E. coli, to produce the mutant enzyme in the presence of chaperone molecules. Materials and Methods: Q59LAsp gene was cloned in...

En este texto se examina el fructífero diálogo sobre la naturaleza de historia consignado en Diario lectura que lleva Ernesto Volkening (1908-1983) los Escolios Nicolás Gómez Dávila (1913-1994). Entre escolios y comentarios hila una concepción que, a pesar ser fragmentaria, guarda auspiciosa coherencia. El historiador, hecho histórico individuo son conceptos centrales respecto cuales compone pe...

using mutation specific pcr assay and analysis of position 108 amino acid in dihydrofolate reductase-thymidilate synthase gene in 70 plasmodium falciparum isolates of malarial patients from southern areas of iran, showed 4 different situations: iwild type (108-ser) ii-mutant type (108-thr) iii-mutant type (108-asn) and iv-mixed wild and mutant type (108-ser+thr) with frequency of 58(82.8%), 2(2...

Low threshold Ca2+ currents mediated by T-type channels underlie burst spike activities of relay neurons in the thalamus. We have previously reported that knock-out mice for T-type channels show an enhanced nociceptive response to visceral pain, accompanied by an increase in tonic spikes in the absence of burst spikes in thalamic relay neurons. These results raised a possibility that T-type cha...

Los caudales de agua riego se han medido tradicionalmente en Valencia mediante una medida aforo llamada fila, la que hasta ahora desconocía su verdadera naturaleza y valor, a pesar ser un tema ampliamente discutido desde hace siglos. En este artículo plantea solución esta discusión, estableciéndose fila o hila, herencia andalusí, tenía triple condición según cantidad disponible. Así, habitualme...
