Background and objective: Human is the only host of hepatitis C virus. This virus has a positive single stranded RNA and lipoprotein envelop that has 7 confirmed genotypes. According to studies, genotypes 1a, 3a and 1b are the most common genotypes in Iran. No effective vaccine against HCV infection has been developed instead, advances in antiviral treatment using drugs that directly affect spe...
background: hepatitis c is a disease with significant global impact. the distribution of hepatitis c virus (hcv) genotypes in mashhad (the northeast and the biggest city after the capital of iran) is unknown. the purpose of this study was to determine the prevalence of hcv genotypes among hcv seropositive patients, and to study the relationship between types, virologic and demographic features ...
OBJECTIVE The 16-Year Long-Term Follow-Up (LTF) to the pivotal interferon-beta-1b (IFNbeta-1b) trial explored clinical, MRI, cognitive, and patient-reported outcomes. Here, we report the safety assessments. METHODS In the pivotal study, 372 patients were randomized to placebo (n = 123), IFNbeta-1b 50 microg (n = 125), or IFNbeta-1b 250 microg (n = 124) subcutaneously every other day for up to...
BACKGROUND In the Betaseron/Betaferon in Newly Emerging Multiple Sclerosis for Initial Treatment (BENEFIT) study, interferon beta-1b delayed conversion to multiple sclerosis in patients with a first clinical event and at least 2 clinically silent brain magnetic resonance imaging (MRI) lesions. OBJECTIVE To examine detailed MRI findings from the first 2 years of this trial. DESIGN Double-bli...
BACKGROUND The human sex hormone-binding globulin (SHBG) gene comprises at least 6 different transcription units (TU-1, -1A, -1B, -1C, -1D and -1E), and is regulated by no less than 6 different promoters. The best characterized are TU-1 and TU-1A: TU-1 is responsible for producing plasma SHBG, while TU-1A is transcribed and translated in the testis. Transcription of the recently described TU-1B...
[(3)H]SSR-149415 is the first tritiated nonpeptide vasopressin V(1b) receptor (V(1b)R) antagonist ligand. It was used for studying rodent (mouse, rat, hamster) and human V(1b)R from native or recombinant origin. Moreover, a close comparison between the human and the mouse V(1b)R was performed using SSR-149415/[(3)H]SSR-149415 in binding and functional studies in vitro. [(3)H]SSR-149415 binding ...
We examined effects of c-fos overexpression on the development and property of peritoneal B-1 cells using transgenic (H2-c-fos) mice carrying the c-fos gene under the control of the constitutive H-2Kb promoter. The number of B-1b cells in the peritoneal cavity of H2-c-fos mice was 4-fold larger than that in control littermates. Although the numbers of total peritoneal B cells and B-1a cells wer...
Teng, Xingwu, Hanfang Zhang, Connie Snead, and John D. Catravas. Molecular mechanisms of iNOS induction by IL-1b and IFN-g in rat aortic smooth muscle cells. Am J Physiol Cell Physiol 282: C144–C152, 2002;—In rat aortic smooth muscle cells (RASMC), interferon (IFN)-g enhanced nitrite accumulation and type II nitric oxide synthase (iNOS) protein expression induced by interleukin (IL)-1b. IFN-g a...
This is the first report of molecular characterization of US erysipelas field isolates and vaccine strains of Erysipelothrix rhusiopathiae by pulsed-field gel electrophoresis (PFGE). Erysipelas in pigs is mainly caused by E. rhusiopathiae serotypes 1a, 1b, and 2. In 2001, erysipelas reemerged as a clinical problem in pigs in the midwestern United States. In this work 90 erysipelas isolates (58 ...
Prototype galectins, endogenously expressed animal lectins with a single carbohydrate recognition domain, are well-known regulators of tissue properties such as growth and adhesion. The earliest discovered and best studied of the prototype galectins is Galectin-1 (Gal-1). In the Gallus gallus (chicken) genome, Gal-1 is represented by two homologs: Gal-1A and Gal-1B, with distinct biochemical pr...
