OBJECTIVE To systematically evaluate the effectiveness of the gonadotropin-releasing hormone (GnRH) antagonist on in vitro fertilisation (IVF) in patients with polycystic ovary syndrome (PCOS). METHODS Nine types of databases were searched by computer, and nine types of relevant journals were searched manually. Randomized, controlled trials of the effects of the GnRH antagonist and GnRH agoni...

The precise mechanism(s) underlying the thermal hyperemic response to local heating of human skin are not fully understood. The purpose of this study was to investigate a potential role for H1 and H2 histamine-receptor activation in this response. Two groups of six subjects participated in two separate protocols and were instrumented with three microdialysis fibers on the ventral forearm. In bo...

OBJECTIVE To investigate the effectiveness of GnRH antagonist multiple-dose protocol (MDP) with oral contraceptive pill (OCP) pretreatment in poor responders undergoing IVF/ICSI, compared with GnRH antagonist MDP without OCP pretreatment and GnRH agonist low-dose long protocol (LP). METHODS A total of 120 poor responders were randomized into three groups according to controlled ovarian stimul...

Abstract Study question Is there any difference in embryo ploidy rates following progesterone primed ovarian stimulation (PPOS) using micronized or GnRH antagonist protocol? Summary answer Pituitary downregulation with a PPOS protocol results comparable number of euploid blastocysts protocol. What is known already Although the consider by most gold standard for controlling LH surge during IVF/I...

Abstract Study question Does late follicular phase stimulation yield similar outcomes compared with conventional early in a GnRH antagonist protocol oocyte donors? Summary answer Late is not inferior terms of number oocytes to protocol. What known already In patients undergoing fertility preservation for medical reasons, has been effectively used, resulting numbers total and mature obtained, ma...

Reusable silica supported perchloric acid and potassium bisulphate have been prepared and explored as green catalysts for thiocyanation of aromatic compounds under conventional and solvent free microwave assisted conditions. The microwave assisted protocol exhibited remarkable rate accelerations and offered selective thiocyanation of aromatic and hetero aromatic compounds in good yields. Reacti...

objective(s):estrogen (e2) has neuroprotective effects on blood-brain-barrier (bbb) after traumatic brain injury (tbi). in order to investigate the roles of estrogen receptors (ers) in these effects, er-α antagonist (mpp) and, er-β antagonist (phtpp), or non-selective estrogen receptors antagonist (ici 182780) were administered. materials and methods: ovariectomized rats were divided into 10 gr...

introduction: anxiety is among the most common and treatable mental disorders. adrenergic and cannabinoid systems have an important role in the neurobiology of anxiety. the elevated plus-maze (epm) has broadly been used to investigate anxiolytic and anxiogenic compounds. the present study investigated the effects of intraperitoneal (ip) injection of cannabinoid cb1 receptor antagonist (am251) i...

Electromyography (EMG) is a research tool used in gait analysis, muscle coordination evaluation, clinical evaluation and sports techniques. can provide an insight into neural adaptations, cross education effects, bilateral contraction deficiencies, antagonist activity exercise-related movements. While there are clear benefits to using EMG professions, accessibility, cost, difficulty interpretin...
