background: receptor for hyaluronic acid mediated motility (rhamm) has intracellular and extracellular functions. in this study, we focus on the expression of rhamm in the rat uterus during estrous cycle and implantation period. methods: the female adult rats were divided into six groups following estrous cycle determination (n=36). the utreri of rats were collected according to estrous cycle p...

background: endometrial secretion analysis is a non-invasive and promising method in evaluation of endometrial receptivity. objective: the aim of the present study was to assess the relationship between the success rate of ivf procedures and some endometrial secretion cytokines, including interleukin-1β (il-1β), tumor necrosis factor (tnf-α), interferon gamma-induced protein 10 (ip-10), and mon...

Nickel is widely used as a fcc model material to obtain insight into fundamental mechanisms of radiation damage. This work presents irradiation high-purity nickel using self-ions at 450 °C and fine analysis dislocation loops in specimens prepared by Focus Ion Beam Transmission Electron Microscopy. For the first time our knowledge, an inversion loop nature (vacancy-type irradiated zones v.s. int...

Background: Apoptosis is a process that plays an important role during early stage of implantation. The aim of this study was to investigate the incidence of apoptosis in mice endometrium after ovarian stimulation at implantation period. Methods: NMRI female mice were divided into two groups: 1) control group, which were rendered pseudopregnant by vaginal stimulation and 2) experimental group, ...

We report on the formation of a tellurium nanosheet with MoOx cap by thermal annealing ion-implanted 2H–MoTe2 multilayers. The presence crystal defects generated ion implantation at an energy 90 keV accelerates incorporation O atoms and surface desorption Te in defective MoTe2 during annealing, subsequently, is formed around bottom regions due to segregation. For angle-resolved Raman spectrosco...

stabilizations and atomic level quadrupole coupling constant (cq) properties have been investigated for graphene–like monolayers (g–monolayers) of boron nitride (bn), boron phosphide (bp), aluminum nitride (aln), and aluminum phosphide (alp) structures. to this aim, density functional theory (dft) calculations have been performed to optimize the model structures and also to evaluate the cq para...

We introduce a new class of spin-on dopants composed of organic, dopant-containing polymers. These new dopants offer a hybrid between conventional inorganic spin-on dopants and a recently developed organic monolayer doping technique that affords unprecedented control and uniformity of doping profiles. We demonstrate the ability of polymer film doping to achieve both p-type and n-type silicon by...

Background: The process of implantation involves the interaction of the human embryo and the uterine epithelium. Failure of implantation is a major reason for infertility in women and the inability to achieve endometrial receptivity is responsible for much of the failure of reproductive technologies. Management of repeated implantation failure despite transfer of good-quality embryos still rema...
