introduction: although hippocampus is the most famous brain area involved in temporal lobe epilepsy, hippocampal kindling (hk) develops very slowly. hence, rapid kindling is usually preferred to the traditional kindling and it is widely used. in this article we aimed at finding the optimal stimulus pattern, which yields the fastest hk rate. methods: stimulus patterns with different duration (2,...

objective: to compare the pregnancy outcomes achieved by in vitro fertilization (ivf) between minimal stimulation and conventional antagonist protocols in poor ovarian responders (pors). materials and methods: in this randomized controlled trial, 77 pors undergoing ivf were selected and divided into two groups. first group was the minimal stimulation group (n = 42) receiving 100 mg/day clomiphe...

background: poor ovarian response to controlled ovarian stimulation is one of the most important interest points in assisted reproduction. mild ovarian stimulation seems to be preferable to high dose of fsh regimens in women with a history of poor ovarian response in previous protocol. clomiphene citrate and letrozole alone or in combination with fsh have been used in mild ovarian stimulation p...

background: to compare a flexible, multi-dose gnrh antagonist protocol with a long gnrh .agonist protocol in poor respo materials and methods: a randomized clinical trial of 70 poor responder patients (35 patients in gnrh antagonist protocol and 35 patients in long gnrh agonist protocol) was performed at royan institute, tehran, iran. both groups were given a fixed dose of human menopausal gona...

abstract physical injuries during taekwondo competitions often happen due to physical contacts during fighting; therefore, a training protocol was designed in line with the physiological stress of a real competition according to la, hr and rpe changes so that the athletes could perform the techniques with a pad instead of a real opponent. for this purpose, 12 professional taekwondo players from...

objective: this study was conducted to compare the results of fixed versus flexible gnrh antagonist protocols in controlled ovarian stimulation for intra cytoplasmic sperm injection (icsi) in patients with pcos. materials and methods: a randomized clinical trial was performed on 100 pcos women, who were admitted to a tertiary infertility clinic and were candidate for ivf/icsi. they were divided...

Background To compare a flexible, multi-dose GnRH antagonist protocol with a long GnRH .agonist protocol in poor respo MaterialsAndMethods A randomized clinical trial of 70 poor responder patients (35 patients in GnRH antagonist protocol and 35 patients in long GnRH agonist protocol) was performed at Royan Institute, Tehran, Iran. Both groups were given a fixed dose of human menopausal gonadotr...

The goal of ovarian Stimulation for assisted reproductive technologies (ART) is obtaining multifollicular growth ovarian hyper stimulation syndrome (OHSS) is one of the most Severe and also potentially Life-threatening complications, which happens in 1-10% of IVF cycles. The most common risk factors which are related to OHSS are polycystic ovarian syndrome (PCOS), younger age, high preovulatory...

Background The conventional ovarian stimulation protocol aims to provide the maximum number of oocytes for fertilization which is lead to several embryos for selecting to transfer. There are some complications in this case like; OHSS, Multiple gestation, Time consuming, Patients discomfort, High costs, Emotional distress and Reduced implantation rate due to the embryo- endometrial asynchrony. R...

background: recently different studies suggested that discontinuation of gonadotrophin releasing hormone analogue (gnrha) at beginning of ovarian stimulation (improvement of ovarian response to gonadotrophins) may have some benefit to poor responder patients in invitro fertilization (ivf) cycles. objective:the efficacy of gnrha stop protocol in poor responder patients in ivf cycles was assessed...
