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...

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...

Let G be a graph with vertex set V(G) and edge E(G), let d(u,w) denote the length of u−w geodesic in G. For any v∈V(G) e=xy∈E(G), d(e,v)=min{d(x,v),d(y,v)}. distinct edges e1,e2∈E(G), R{e1,e2}={z∈V(G):d(z,e1)≠d(z,e2)}. Kelenc, Tratnik Yero [Discrete Appl. Math. 251 (2018) 204-220] introduced notion an resolving dimension graph: A subset S⊆V(G) is if |S∩R{e1,e2}|≥1 for dimension, edim(G), minimu...

Studies have shown that estradiol-17β (E2) regulates gonadotropin-releasing hormone (GnRH) and GnRH receptor expression in hypothalamus and pituitary. Several studies have shown that GnRH and its receptor are also expressed in peripheral reproductive organs and little is known about their regulations. In this study, GnRH and GnRH receptor structures, functions, their peripheral expressions and ...

In this paper we study Cohen-Macaulay local rings of dimension d, multiplicity e and second Hilbert coefficient e2 in the case e2=e1−e+1. Let h=μ(m)−d. If e2≠0 then our can prove that type(A)≥e−h−1. type(A)=e−h−1 show associated graded ring G(A) is Cohen-Macaulay. next when type(A)=e−h determine all possible series A. depthG(A) completely determines Series

conclusions this study provided conserved b-cell epitopes and peptides that can be useful for designing entry inhibitors and vaccines able to cover a global population, especially where genotype 5a is common. results differences in the probability of glycosylation in e1 and e2 regions were observed in this study. three conserved antigenic b-cell epitopes were predicted in the e2 regions and als...

Abstract Ubiquitination is an important modification process in eukaryotic organisms, and ubiquitin ligase (E3) the most diversified component of this system. APIP6 (AvrPiz-t interacting protein 6) one E3s rice, involved recognition AvrPiz-t, effector from pathogen Magnaporthe oryzae , for initiation host defense against M. . However, structural detail how performs its function remains elusive....
