In the present study, we investigated the influence of exogenous estrogen on embryo survival after transfer into prepubertal gilts in which estrus had been induced. In the first experiment, estrus was induced in prepubertal gilts by the administration of 1,000 IU of eCG and 750 IU of hCG every 72 h. Several blastocysts were recovered on d 6 (d 0 is the day of hCG administration), and 1 embryo w...

hydrosalpins (dilatation of fallpian tube that can be seen by hysterosalpingogeraphy. laparoscocpy, and in severe cases by sonography) is one of the probable confounding factors of assited – reproduction therapy (art) outcomes. this cohort study is conducted to determine the effects of hydrosalpins on ivf-et outcomes. for this, of the total number of patients who had approached the infertility ...

the main factors affecting pregnancy and implantation rates are uterine receptivity, embryo quality, and transfer efficiency. embryo transfer (et) is the last step of critically important procedure of in vitro fertilization (ivf) and probably the least successful step in assisted reproductive technology (art) treatment cascade; though simple in most of the cases, it may pose to be the most diff...

background: embryo transfer (et) has traditionally been performed two days after oocyte retrieval. delaying transfer from day two to day three or four would allow for further development of the embryo might therefore optimize the selection of viable and best quality embryos for transfer and may be closer to the physiological time of the entry into the uterus than transfer on day two and might h...

We investigated the influence of maternal salt restriction during mating or gestation on birth rate and offspring growth in Dahl salt-sensitive rats (DS). DS were divided into 5 groups: DS fed a low-salt (0.3% NaCl, w/w) (DS-low) or high-salt (4% NaCl, w/w) diet (DS-high) during mating and DS-high or DS-low during gestation, and DS fed regular chow (0.75% NaCl, w/w) (DS-regular) throughout mati...

background: allogeneic hematopoietic stem cell transplantation (hsct) is a curative treatment option for many patients with acute myeloid leukemia (aml); however, it can lead to complications of graft-versus-host-disease (gvhd) which can affect the quality of life and overall survival. the aim of this study was to assess the effects of both acute and chronic gvhd on survival rate in patients wi...

background: esophageal cancer is often diagnosed in the last stages where the chance of patient’s survival is very low. the aim of this systematic review was presentation of valid estimation of survival in patients with esophageal cancer in different regions of iran. methods: a systematic review was carried out based on the reliable domestic medical databases including: sid, magiran, irandoc an...

this study was conducted to evaluate the effects of beta plus probiotic, a mixture of bacillius leicheniformic and bacillius subtilis , on the growth performance and intestinal microbial flora of caspian trout ( salmo caspius ). a basal diet was formulated and supplemented with beta plus at 0, 0.5 and 1 g kg -1 , leading to three experimental diets. each experimental diet was randomly assigned ...

background breast cancer is the most common cancer among women worldwide. based on the latest iranian national cancer department report, the total number of women registered with breast cancer was 6976 cases during 2007. five year survival is one of the indicators used for evaluation of the quality for care to different types of malignancies including breast cancer. objectives the aim of this s...

background: embryo transfer has received little clinical attention and has been the most inefficient step in in-vitro fertilization (ivf). recent reports have suggested that an awareness of the position and length of the uterus during embryo transfer might be helpful in improving pregnancy rate. objectives: the main objective of the present study was to determine the relation between the length...
