background: estradiol (e2) is required for follicular development and play an important role in embryo implantation. objective: the aim of this study was to assess the impact of serum e2 levels on the day of hcg administration in ivf-icsi patients who are performed controlled ovarian hyperstimulation (coh). materials and methods: a total of 203 women who were undergone one time ivf cyclus were ...

this study was carried out to investigate the effects of different irrigation regimes and planting methods on yield, yield components, morphological traits, and storage characteristics of a local onion cultivar, namely, goli ghesse. the experiment was conducted as a factorial split plot design with rcbd arrangement in four replications and for three years at kheirabad research station. irrigati...

This study focused on hepatosomatic and gonadosomatic index and levels of plasma 17β-estradiol (E2), vitellogenin (Vtg) and total protein and determined the localization of Vtg in the liver during vitellogenesis in female Chalcalburnus tarichi, an endemic cyprinid species living in the Lake Van, Turkey. The levels of plasma E2, Vtg and total protein in female fish increased during vitellogenesi...

Indirect evidence suggests that estrogen is involved in the etiology of breast cancer. Estrogen is also thought to modulate nitric oxide (NO) in human breast tumor tissue via regulation of inducible nitric oxide synthase (iNOS). Objectives of this study were to determine whether estradiol (E2) affects iNOS expression level in breast cancer cells and to study the effect of various concentrations...

Introduction: The development of an effective vaccine against Hepatitis C virus (HCV) is still a target of intensive vaccine research. The HCV envelope proteins E1 and E2 which can induce broadly neutralizing antibodies are the major candidate for this purpose. Different types of expression systems have been used to express these glycoproteins. In this study, an expression system using Pichia p...

Background: Though plausible candidate adhesion systems have been identified, current knowledge of embryo-maternal attachment in human is limited by the inability to conduct well-controlled functional investigations. We have sought a viable medium-throughput model for the identification and functional assessment of molecular markers in the initial epithelial phases of implantation. An ideal mod...

Aim . To study the possible synergistic action of steroid hormones and hormone-specific autoantibodies anti-autoantibodies in conversion ER+/PR+ tumors into ER-/PR- breast cancer patients. Materials Methods Concentrations estradiol (E2) progesterone (Pg) levels idiotypic IgA antibodies (IgA 1 -E2 -Pg) as well anti-idiotypic IgG (IgG 2 were studied serum 979 patients (432 with stage 547 stages 2...

The triphenylethylene antiestrogens, idoxifene (Idox) and toremifene (Tor), are structurally related analogues of tamoxifen (Tam) and were developed to improve the therapeutic index for advanced breast cancer patients. However, the issue of cross-resistance with Tam for these new agents is critical for clinical testing because the majority of breast cancer patients have already received or fail...
