background: with the prevalence of 6-10%, polycystic ovarian syndrome (pcos) is considered the most common endocrinological disorder affecting women in their reproductive age. it has been suggested that genetic factors participate in the development of pcos. follicular development has been considered as one of the impaired processes in pcos. bone morphogenetic protein-15 (bmp-15) gene is a cand...

alkylation of biphenyl with 1-octene was investigated using ((al+c3h7cl)+c2h4) catalysts. the catalytic activity of ((al+c3h7cl)+c2h4) for the alkylation was studied at different temperatures, mol ratios of biphenyl to 1-octene, reaction times and catalyst concentrations. it was shown that using this catalyst has more advantagous than another catalysts. experiments show that by increasing tempe...

a facile and efficient method for the preparation of 1, 1-diacetates of aldehydes is improved.p2o5/sio2 catalyzed 1, 1-diacetates formation from aldehydes in dry media. advantages of this methodare the use of an inexpensive and selective catalyst with high yields in simple operation and shortreaction time under solvent-free conditions.

colorectal cancer (crc) is one of the most common cancers worldwide. understanding of the tumor behavior, in a much closer look, at the molecular level, results in a more effective treatment and accurate prognosis of the disease. from among various genes altered in colorectal cancer k-ras is assumed to be of diagnostic and prognostic significance. k-ras mutations are believed to be a critical e...

abstract introduction: standardized tests in speech therapy mostly focus onlanguage structure rather than the use of language in social context. so, there is a clear need for instruments to assess pragmatic aspects of language. children’s communicationchecklist (ccc) and its revised version, ccc-2, was developed to address this need, however, its psychometric features are unknown in iran. the c...

introduction cr-39 detectors are widely used for radon and progeny measurement in the air. in this paper, using the monte carlo simulation, the possibility of using the cr-39 for direct measurement of radon and progeny in water is investigated. materials and methods assuming the random position and angle of alpha particle emitted by radon and progeny, alpha energy and angular spectrum that arri...
