the condensation reaction of 5-(4-aminophenyl)-4-phenyl-1,2,4-triazole-3-thione with salicylaldehyde, 4-hydroxybenzaldehyde, 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde, 2-nitrobenzaldehyde, 3-nitrobenzaldehyde, 4-nitrobenzaldehyde and 4-methoxybenzaldehyde in methanol results in series of new schiff bases. the structure of schiff bases were confirmed by 1h nmr, 13c nmr, ir and mass spectro...

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: addition of amino acids to the culture medium is beneficial for embryonic development in many species. objective: the objective of this study was to investigate the effects of amino acids on the in vitro maturation and embryonic development of the bovine oocyte. materials and methods: bovine ovaries were collected from a local abattoir and brought into laboratory. cumulus-oocyte com...

background: ovarian pregnancy constitutes 0.15-3% of all ectopic pregnancies. the incidence of ectopic pregnancy is on the rise owing to evolution in assisted reproductive techniques (art). the incidence reported following in vitro fertilization (ivf) or embryo transfer (et) is 0.27% per clinical pregnancy. case: we present a case of a 13-weeks ovarian pregnancy following ivf-et and through a r...

background: supplementation of luteal phase with progesterone is prescribed for women undergoing routine ivf treatment. objective: the objective of this study was to compare the efficacy of three types of progesterone on biochemical, clinical and ongoing pregnancy rates and abortion and live birth rates. materials and methods: a prospective randomized study was performed at royan institute betw...

background: endometriosis is a common hormone-dependent gynecologic disease with a high recurrence. laparotomy or laparoscopy is the standard surgery for the large endometrioma. also, sclerotherapy is basically used to treat different diseases one of which is endometrioma. objective: the study was designed to assess the value of transvaginal ultrasound-guided ethanol sclerotherapy in patients w...

The aim of the present study was to investigate the effect of follicle stimulating hormone (FSH) on survival, activation and growth of ovine primordial follicles using histological studies. Pieces of ovine ovarian cortex were obtained and cultured for 6 days in Minimum Essential Medium supplemented with or without FSH (50 ng/mL). These fragments were then process to be used for histology compar...

High levels of ambient air pollution are associated with exacerbation of asthma and respiratory morbidity, yet little is known concerning the mechanisms of inflammation and toxicity by components of inhaled particulate matter (PM). Brief inhalation of PM 2.5 (particles of an aerodynamic diameter of , 2.5 microns) (300 m g/m 3 air for 6 h followed by a period of 24 h in clean air) by either C3H/...
