the families of tgf-β proteins are the most important growth factors in the ovary for growth and differentiation of early ovarian follicles. three related oocyte-derived members of the transforming growth factor-β superfamily namely growth differentiation factor 9 (gdf9), bmp15 and bmpr-ib have been shown to be essential for follicular growth and ovulation. different mutations in the gdf9 gene ...

kinetic studies were made of the reactions between triphenylphosphine 1, dialkyl acetylenedicarboxylates 2 in the presence of nh-acid, such as maleimid (as a protic/nucleophilic reagent) 3. to determine the kinetic parameters of the reactions, they were monitored by uv spectrophotometery. the second order fits were automatically drawn and the values of the second order rate constant (k2) were a...

Fluorescence resonance energy transfer substrates of sortase A are too expensive to be used to roughly screen high-throughput sortase A inhibitors. This makes therapeutic strategies difficult to realize in a clinical therapeutic use. Instead, we design here an LPETG-EGFP (leucine, proline, glutamic, threonine and glycine-enhanced green fluorescence) protein displayed on a yeast surface as a sub...

poly-(alkylcyanoacrylate) ester particles have been used for the preparation of different formulations ranging from ophthalmic delivery systems to cancer chemotherapy carriers in clinic. the aim of this study was to prepare and characterize poly-(methyl ethyl cyanoacrylate) (pmeca) particles containing 5-aminosalicylic acid (5-asa). pmeca particles were prepared using the inverse emulsification...

Poly-(alkylcyanoacrylate) ester particles have been used for the preparation of different formulations ranging from ophthalmic delivery systems to cancer chemotherapy carriers in clinic. The aim of this study was to prepare and characterize poly-(methyl ethyl cyanoacrylate) (PMECA) particles containing 5-aminosalicylic acid (5-ASA). PMECA particles were prepared using the inverse emulsification...

The Japanese and English White quails are widespread strains and belongs to the Galliformes order, Phasianidae family, Coturnix genus  and Japonica species. These birds are likely to be well-adapted to the hard conditions and resistance to diseases as it has attained economic importance as an agricultural species. In the current study, the genetic variation of Japanese and English White  quail ...

background: extracted sperm from the testis have poor motility. moreover, their motility changes during their journey through epidydimis. meanwhile, they face high concentration of l-carnitin. in addition, lactate dehydrogenase c4 (ldh-c4) gene disorders has been shown to cause impaired sperm motility, leading to infertility in male mice. the aim of this study was to evaluate sperm motility and...

based on experiments showing immunomodulatory effects of garlic (allium sativum l.), we sought to see whether allium hirtifolim boiss., belonging to the same genus of garlic, has any effect on immune responses. hydroalcoholic extract and polyphenolic fraction of a. hirtifolium bulbs were prepared. allicin (diallyl thiosulfinate), a biologically active component, was identified in plant bulbs by...
