because many diseases are multifactorial disorders, the scientific progress in genomics and genetics should be taken into consideration in public health research. in this context, genomic databases will constitute an important source of information. consequently, it is important to identify and characterize the state's role and authority on matters related to public health, in order to verify w...

Drosophila melanogaster has played a pivotal role in the development of modern population genetics. However, many basic questions regarding the demographic and adaptive history of this species remain unresolved. We report the genome sequencing of 139 wild-derived strains of D. melanogaster, representing 22 population samples from the sub-Saharan ancestral range of this species, along with one E...

background: the purpose of the study was to compare clinical pregnancy and delivery rates with fresh and frozen embryo transfer in patients admitted to shiraz- human assisted reproductive center with ovarian hyperstimulation syndrome (ohss). methods: ohss patients randomly divided in two groups, group a (n=50) with fresh embryo transfer and group b (n=50) with frozen embryo transfer. we used vi...

micrornas (mirna) are a class of noncoding and regulatory rna molecules about 22 nucleotides in length. micrornas regulate gene expression by an rna interfering pathway through cleavage or inhibition of the translation of target mrna. many mirnas have been reported for their important roles in developmental processes in various animals, but there is limited information about cattle and sheep mi...

many investigators are interested in finding the new cultural systems that can support the in vitro development of pre-implantation embryos better. previous studies suggested that growth factors such as epidermal growth factor (egf) are important in pre-implantation embryo development and implantation process. on the other hand, it is very important to support post thaw development of frozen em...

nitroimidazole compounds have been traditionally used in the veterinary and human medicine, but their uses are sometimes associated with some side effects. toxicopathological effects of nitroimidazoles have always been a major concern. there is scant information available about the pathological alterations of nitroimidazole compounds in the embryo. the objective of this study was to determine t...

infectious agents cause disease in virtually any susceptible hosts. in the poultry production and medicine, pathogens were eliminated from a line of a breeder by injection of antibiotics into hatching eggs. there is little information available describing the safety of the folate antimetabolite/sulfonamide class of antibiotics on the game birds embryonated eggs. the objective of this study was ...

The aim of this study was to analyze the incidence of stage of embryonic development, embryo quality and the time of transfer on pregnancy rate in embryo transfer program timed. We were worked a total of 23Holsteincowsasembryo donors, super-ovulated with gonadotropin of pregnant mare serum (PMSG) (2500 3000UI).69 cows were used as recipients of Holstein dairy heifers with an age of20 months and...
