background: determination of oocyte fertilization and embryo quality are one of the most important purposes in art cycles. follicular fluid provides an important microenvironment for development of oocytes and some biochemical characteristics of the follicular fluid, such as pregnancy-associated plasma protein-a (papp-a), may play an important role in prediction of success rate of art. objectiv...
This paper presents a new circuit to configure power amplifier (PA) for return-to-zero on-off-keying (RZ-OOK) transmitters. The proposed PA works as a multimode structure with configurable data rate and output power. The programmable data rate function is achieved by duty cycle adjustment of input data and producing input RZ-data by a simple circuit, which leads to a linear scale of data rate w...
Background: Animal and in vitro studies have shown that 25-OH vitamin D plays a significant role in different parts of body. Few data exist about the role of 25- OH vitamin D in reproduction. Insufficient levels during pregnancy are potentially associated with increased risk of preeclampsia, insulin resistance and gestational diabetes mellitus. Recently, few studies have assessed the prognostic...
Introduction & Objective: Women during their lifetime experience a variety of physiological changes that can affect their physiological capacity to perform exercise and induce reduction in achieving the benefits of training. So, finding the best time to perform maximum physical performance is essential. Sports drink consumption can also help to enhance athletic performance. The purpose of thi...
Background: Cigarette smoke contains many oxidants and may alter the human reproduction by inducing oxidative stress (OS) in both active and passive smokers. This study was designed to evaluation the effect of environment tobacco smoke (ETS) exposure on oxidative stress in follicular follicle and assisted reproduction outcomes. Materials and Methods: A prospective study was carried out on 236 i...
introduction: in this study human follicular fluid has been used as an enzyme- rich solution to prevent embryo implantation in mice which resulted in reduction of pregnancy rate. materials & methods: 2-6 month nih female mice were used to study the effect of interauterine follicular fluid on the fertility rate. 226 plugged female mice were caged in three groups: control, placebo, and experiment...
in this paper, asymmetric effects of exchange rate fluctuation (according to positive and negative shocks) on real output were investigated. in the meantime, the study of behaviour of real output growth in iran’s economy over the period 1338-1386 was done. in specification of the output growth equation, in spite of considering positive and negative shocks of exchange rate, the effects of other ...
In order to evaluate the effects of short course administration of dexamethasone (DEX) combined with clomiphene citrate (CC) in CC-resistant patients with polycystic ovary syndrome (PCaS) and normal DHEAS, a prospective, double blind, placebo controlled, randomized study was undertaken at referral university hospitals, Two-hundred and thirty women with PCOS and normal DHEAS who failed to ...
The development of both the mammalian oocyte and the somatic cell compartments of the ovarian follicle is highly coordinated; this coordination ensures that the ovulated oocyte is ready to undergo fertilization and subsequent embryogenesis. Disruption of this synchrony results in oocyte developmental failure. Communication between the oocyte and companion somatic cells is essential for successf...
