Objective(s):Estrogen is a sexual hormone that has prominent effects on reproductive and non-reproductive tissues. The aim of this study is to evaluate the effects of estrogen on the proliferation and neural differentiation of human adipose derived stem cells (ADSCs) during neurogenic differentiation. Materials and Methods: Isolated human ADSCs were trans-differentiated in neural induction med...
Objective(s): Exposure to electromagnetic fields (EMF) emitted from mobile phones may cause a deleterious effect on human health and may affect the male reproductive system. Crocin, a carotenoid isolated from Crocus Sativus L. (Saffron), is a pharmacologically active component of saffron. So, this study was conducted to investigate the protective effect of crocin on t...
In 1994, Jain and Bruce proposed an index--HARI, an acronym for Helping Individuals Achieve their Reproductive Intentions--to measure success or failure of family planning programs with a reproductive health orientation. HARI applies the principle of individual rights and well-being to the assessment of these programs. The index measures two components: the achievement of an individual's reprod...
Morphological changes in the sexual organs of the pulmonates were observed throughout a year and correlated with reproductive-cycle periods. Reproductive-organ weights of the snail Megalobulimus abbreviatus were recorded seasonally and gonad sections were analyzed morphologically. The weights were used to obtain the organosomatic index. Mean oocytic diameter and oocytic maturation index were ba...
As a scientific achievement of the modern world, cloning has caused both fears and hopes for the future of the humankind. It is categorized into human and non-human cloning, each of which are subdivided into therapeutic and reproductive subtypes. Of these subtypes, only the reproductive category has produced much controversy, but there is not much debate on animal cloning. Human cloning for the...
backgroundseveral studies have examined the relationship between human development index (hdi) and various health outcomes. the aim of this study was to investigate the relationship between hdi, and infant mortality rate, mortality rate of children under one year and under 5 years, maternal mortality rate, and total fertility rate.materials and methodsin this ecologic study, data on hdi, total ...
there has been relatively little empirical analysis of the role played by cultural-social-economic policies to promote entrepreneurship. governments, for instance, conduct different entrepreneurship promotion policies. financial assistance and easing of bureaucratic rules are provided to improve the entrepreneurship process in a country. entrepreneurs benefit from education and skills, which ar...

INTRODUCTION In Triatominae, reproductive efficiency is an important factor influencing population dynamics, and a useful parameter in measuring a species' epidemiological significance as a vector of Trypanosoma cruzi (Chagas, 1909). The reproductive efficiency of triatomines is affected by food availability; hence, we measured and compared the effects of feeding frequency on the reproductive p...
BACKGROUND Reproductive factors provide an early window into a woman's coronary heart disease (CHD) risk; however, their contribution to CHD risk stratification is uncertain. METHODS AND RESULTS In the Women's Health Initiative Observational Study, we constructed Cox proportional hazards models for CHD including age, pregnancy status, number of live births, age at menarche, menstrual irregula...
