Let G be a connected graph and g non-negative integer. A vertex set S of is called g-extra cut if G−S disconnected each component has at least g+1 vertices. The connectivity the minimum cardinality one cut. For two graphs G1=(V1,E1) G2=(V2,E2), strong product G1⊠G2 defined as follows: its V1×V2 edge {(x1,x2)(y1,y2)|x1=x2 y1y2∈E2; or y1=y2 x1x2∈E1; x1x2∈E1 y1y2∈E2}, where (x1,x2),(y1,y2)∈V1×V2. ...

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 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...

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 ...
