BACKGROUND This study was carried out to search for mutations in the gene encoding for Non- Structural Protein 5A, specifically in the interferon sensitivity determining region of hepatitis C virus (HCV) genotype 3a, isolated from serum samples of patients not responding to treatment with oral Ribavirin and Interferon alpha injections. METHODS This descriptive case series was conducted on HCV...
Objective: The use of GnRH antagonist versus GnRH agonist in poor responder for patient undergoing ovarian hyperstimulation and in vitro-fertilization was compared. Materials and Methods: In this study, 23 patients underwent ovarian hyperstimulation with recombinant FSH followed by the use of GnRH antagonist (Cetrorelix) 0.25mg during the late Follicular Phase. These patients were compared to 2...
PURPOSE To evaluate the efficiency and efficacy of corifollitropin alfa (follicle-stimulating hormone-carboxy terminal peptide) in the treatment of poor responder patients. METHODS A total of 85 poor responder patients with a mean age 40.2±3.9 years entered our assisted fertilization program. The patients were prospectively randomized into two groups based on the ovarian stimulation regimen u...
The cellular requirements for immune response (Ir) gene expression in a T cell proliferative response under dual Ir gene control were examined with radiation-induced bone marrow chimeras. The response to poly(Glu55Lys36Phe9)n (GLphi) requires two responder alleles that in the [B10.A X B10.A(18R)]F1 map in I-Ab and I-Ek/Cd. Chimeras in which a mixture of the nonresponder B10.A parental cells (wh...
This cohort study evaluated whether rescue spontaneous maturation (RSM) could be a valid method to increase the number of embryos available for transfer and whether transfers with RSM-derived embryos would contribute to clinical outcomes of poor-responder patients in ovarian stimulation cycles. The study included 440 patients undergoing intracytoplasmic sperm injection cycles in which fewer tha...
The objective of the present study was prospectively and randomly to evaluate the role of L-arginine in improving uterine and follicular Doppler flow and in improving ovarian response to gonadotrophin in poor responder women. A total of 34 patients undergoing assisted reproduction was divided in two groups according to different ovarian stimulation protocols: (i) flare-up gonadotrophin-releasin...
Resistance to infections with Heligmosomoides bakeri is associated with a significant quantitative trait locus (QTL-Hbnr1) on mouse chromosome 1 (MMU1). We exploited recombinant mice, with a segment of MMU1 from susceptible C57Bl/10 mice introgressed onto MMU1 in intermediate responder NOD mice (strains 1094 and 6109). BALB/c (intermediate responder) and C57Bl/6 mice (poor responder) were inclu...
Trust is an essential component of good social outcomes and effective economic performance. This is particularly true in environments such as the Prisoner’s Dilemma or standard public-goods games, where the equilibrium in a one-shot case involves strictly uncooperative behavior. Evolutionary biologists have developed the notion of indirect reciprocity, whereby favorable or unfavorable actions b...
An optimized atrioventricular (AV) interval can maximize the benefits of cardiac resynchronization therapy (CRT). If programmed poorly, it may curtail beneficial effects of CRT. AV optimization will not convert non-responder to responder, but may convert under-responder to improved status. There are many echocardiographic techniques for AV optimization but there is no universally accepted gold ...
An inability to discern resistant cells from bulk tumour cell population contributes to poor prognosis in Glioblastoma. Here, we compared parent and recurrent cells generated from patient derived primary cultures and cell lines to identify their unique molecular hallmarks. Although morphologically similar, parent and recurrent cells from different samples showed variable biological properties l...
