Cognitive reserve (CR) has been proposed as a latent variable that can account for the frequent discrepancy between an individual's underlying level of brain pathology and their observed clinical outcome. A possible behavioral manifestation of CR is best strategy choice. Older adults have been shown to choose sub-optimal strategies for performing various tasks. The present study attempted to in...

objective: basal fsh levels reflect ovarian response and more formed embryos. we investigated a reliable fsh range to retrieve more oocytes and embryos. materials and methods: two hundred patients in art cycles underwent this study from apr 2007 to sep 2008. patients were divided in three groups based on value of fsh: group a≤8 iu/ml, 8 iu/ml < group b≤10 iu/ml, group c>10 iu/ml and results of ...

diminished ovarian reserve (dor) significantly decreases the success rate of the assisted reproductive technique (art). in this study, we assessed the effect of melatonin on the art outcomes in women with dor. a double-blinded, randomized, clinical trial was performed on 80 women with dor as a pilot study in shiraz, between 2014 and 2015. dor was defined as the presence of 2 of the following 3 ...

introduction:we evaluated the performance of muscle perfusion scan (mps) to assess muscle perfusion reserve (mpr) for prediction of incident diabetic foot ulcerations (dfu). methods: we recruited 41 diabetic patients without any history of dfu. five mci 99mtc-mibi was injected intravenously during repetitive dorsal and plantar right foot flexions. then posterior calves were imaged and the count...

in this paper, we will review the foreign exchange market and will try to extract an exchange market pressure and an intervention index for iran by following the weymark (1995) approach to evaluate the central bank of iran’s exchange rate policy during 1368:q1 to 1391:q3. the estimation method employed, is the econometric technique known in the literature as the two-stage least squares (2sls).t...

wind power generation is variable and uncertain. in the power systems with high penetration of wind power, determination of equivalent operating reserve is the main concern of systems operator. in this paper, a model is proposed to determine operating reserves in simultaneous market clearing of energy and reserve by stochastic programming based on scenarios generated via monte carlo simulation ...

objective: the aim of this study was to assess the accuracy of ovarian reserve tests, mainly basal and clomiphene stimulated follicle stimulating hormone (fsh) concentrations. materials and methods : a prospective cohort study was conductedon 120 infertile patients referring to mirza koochak khan hospital for ivffrom 2004 to 2006. all the patients underwent clomiphene citrate challenge test (cc...
