OBJECTIVE This study aimed to investigate the effects of royal jelly (RJ) on catalase, total antioxidant capacity and embryo development in adult mice treated with oxymetholone (OXM). MATERIALS AND METHODS In this exprimental study, 32 male and 96 female adult Naval Medical Research Institute (NMRI) mice (7-9 weeks of age) with a ratio of 1:3 for fertili- zation purposes were randomly divided...

objective: in recent years, amino acids are used in veterinary medicine for many purposes. they injected into hatching eggs to increase chick body weight and performance at hatch, but the adverse effects of amino acids have always been a major concern. there is scant information available about the pathological alterations of amino acids in the chicken embryonated eggs. the objective of this st...

pathogens are an important and significant hazard for human and animal health. in recent years, antibiotics are used to treat different types of infection caused by bacterial agents. in veterinary medicine, antibiotics injected into hatching eggs to eliminate pathogens and prevention of egg transmission of disease, but the adverse effects of drugs have always been a major concern. there is scan...

the major objective of seedless grape breeding program is production of grapes with high quality. breeding of seedless grapes is difficult because the embryos are aborted after fertilization. embryo rescue technique is utilized to obtain plants from crosses between seedless cultivars. in the present study, the effect of paternal genotypes and different iaa concentrations in presence of ba appli...

background: gnrh agonist and antagonist were developed to control the premature release of lh surge. there is some difference between two protocols. objective: we compared the outcome of frozen-thawed embryo transfer in infertile women who used gnrh agonist or antagonist protocol for previous coh cycle and evaluation of any adverse effect of gnrh antagonist on oocyte and embryo. materials and m...

objective: advancements in medical technology have significantly increased the possibility of successful infertility treatment. medical interventions in the initial process of pregnancy that intend to increase the chances of pregnancy create the risk of multifetal pregnancies for both mothers and fetuses. physicians attempt to reduce the numbers of fetuses in order to decrease this risk and gua...

Using a system of whole-embryo culture, the effect of polybrominated biphenyls (PBB) was investigated on the rates of DNA, RNA, and protein accumulation in rat embryos. Embryos were isolated on the 10th gestational day (sperm day = Day 0) either 4 or 24 hr after maternal administration. The cultivation period was for 24 or 42 hr. DNA, RNA, and protein accumulation rates were not affected by a 4...

Background: A prerequisite for successful embryo implantation is adequate preparation of receptive endometrium and the establishment and maintenance of a viable embryo. The success of implantation further relies upon a two-way dialogue between the embryo and uterus. However, molecular bases of these preimplantation and implantation processes in humans are not well known. Materials and Methods: ...
