For many decades, elevated androgens in women have been associated with poor reproductive health. However, recent studies have shown that androgens play a crucial role in women's fertility. The following review provides an overall perspective about how androgens and androgen receptor-mediated actions regulate normal follicular development, as well as discuss emerging concepts, latest perception...

in a survey of the population of behbahan city, carried out in years 1990-91, the mean age was approximated up to 15.2 and 17.5 in the villages and the city, respectively. furthermore, about 27.4% and 27.9% of the corresponding populations were under 5 years of age. the birth rate in the urban and rural areas was about 31.2 and 33.3 per thousand live births. mortality rate related to the immatu...

Adaptation of plants under drought and salinity stress depends directly on the type of soil texture. Therefore, in this research, the morpho-physiological variations of Stachys multicaulis, an Iranian wild endemic plant species, were investigated in different soil textures under drought and salinity stress. For this purpose, plants were cultivated in three different light, medium and h...

The aim of this study was to identify leaf physiological traits, which could be used in selecting high yielding genotypes among 12 sugar beet cultivars grown in two contrasting pedo-climatic environments. In the stressful Site 1 (high temperatures, low rainfall, heavy-textured soil), high yielders had cooler leaves (lower ΔT) and thus, transpired (E) and photosynthesized (A) more. Also, these c...

Drought stress is the most common environmental stress that can significantly influence crop productivity. In this study, morphological and biochemical properties of 17 genotypes of common bean were evaluated under different levels of drought stress and the most sensitive and tolerant genotypes were identified using multivariate analysis. The results indicated that morphological and biochemical...

biosorption of two anionic dyes, eosin y and eosin b, from aqueous solution using saccharomyces cerevisiae was investigated in a batch mode. the influence process parameters such as contact time, initial dye concentration, sorbent dosage, ph and temperature of aqueous solution were studied. the maximum adsorption capacities were found to be at 200 and 100 mg g-1 for eosin y and 1 eosin b, respe...

background: direct observation cannot detect caries under restorations; therefore, the aim of this study was to compare the accuracy of radiographs and diagnodent in detecting caries under restorations in primary teeth using histologic evaluation. materials and methods: a total of 74 previously extracted primary molars (37 with occlusal caries and 37 without caries) were used. class 1 cavity pr...

a greenhouse experiment was carried out to evaluate the effects of salinity stress on growth and macroelements contents of two olive varieties under hydroponic conditions. in the research, one-year old saplings of two olive varieties, ‘zard’ and ‘mission’, were subjected to different salinity levels induced by nacl including 0, 4, 8, 12 and 16 dsm-1 for 5 months. based on the results, total dry...

Phylogenetic comparative methods are increasingly used to give new insights into the dynamics of trait evolution in deep time. For continuous traits the core of these methods is a suite of models that attempt to capture evolutionary patterns by extending the Brownian constant variance model. However, the properties of these models are often poorly understood, which can lead to the misinterpreta...
