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...

background uterine leiomyoma (uls) is the most common gynecological tumor and a significant health concern for many women .the interleukin-1 receptor antagonist (il-1ra) is a naturally occurring cytokine inhibiting interleukin- 1 (il-1) activity by binding to the il-1 receptors without signal transduction. objectives the aim of this study was to investigate the association between interleukin-1...

the main objective of this study was assessment of hormonal treatments effects on sperm quality improvement in barbus sharpeyi. results showed differences in effects of treatments with lhrha2, lhrha2 combined with a dopamine antagonist (met), and cpe (carp pituitary extract) on parameters of sperm volume, motility, spermatocrit, biochemical indices of seminal plasma and sperm efficiency on arti...

objective: argemone mexicana is a papaveracea plant; some reports have shown their antibacterial, anti-cancer, sedative and probably anti-anxiety properties. from their aerial parts, flavonoids and alkaloids have been isolated, which are intrinsically related to some actions on the central nervous system. the aim of this study was to evaluate the anxiolytic-like effects of the plant, using its ...

background: gonadotropin-releasing hormone (gnrh) plays essential roles in embryo implantation, invasion of trophoblastic tissue, and steroid synthesis in the placenta. objective: the aim of this study was to evaluate the effect of gnrh antagonist administration on pregnancy outcomes in early implantation period. materials and methods: in this retrospective study, 94 infertile women undergoing ...

Pseudomonas aeruginosa is a bacterial pathogen that causes various kinds of infections. The use antibiotics usually done to treat the infection. However, has resistance abilities can avoid efficacy antibiotics. emergence drug events encourages need for discovery new antibiotic drugs, one which comes from fungals secondary metabolite. Soil fungi mangrove ecosystems have not been studied much. In...

The stressosome is a 1.8 MDa cytoplasmic complex that controls diverse bacterial signaling pathways. Its role is best understood in Bacillus subtilis, where it activates the σB transcription factor in response to a variety of sharp environmental challenges, including acid, ethanol, heat or salt stress. However, details of the signaling mechanism within the stressosome remain uncertain. The core...

The most important bacterial pathology currently occurring in Chilean freshwater salmon farming is the cold-water disease produced by the psychrotrophic bacteria Flavobacterium psychrophilum. The main aim of this study was to characterize the inhibitory activity of an antagonist strain on the formation of biofilms of a F. psychrophilum strain. The antagonistic strain Pseudomonas fluorescens FF4...
