Retinitis pigmentosa 2 (RP2) gene is responsible for up to 20% of X-linked retinitis pigmentosa, a severe heterogeneous genetic disorder resulting in progressive retinal degeneration in humans. In vertebrates, several bodies of evidence have clearly established the role of Rp2 protein in cilia genesis and/or function. Unexpectedly, some observations in zebrafish have suggested the oocyte-predom...

Background & aim: Maternal-fetal attachment has an important effect on mother's identity as well as maternal and fetal health. Moreover, this concept is considered as a crucial issue for the improvement of children emotional development. Regarding the Islamic recommendations on maternal-fetal attachment and its correlation with maternal affection, this study was conducted to review the importan...

Plants adapt to environment by plastic growth which will be transferred to offspring through transgenerational effect. Performance and response of maternal and offspring plant will affect population dynamics and community composition. However, it is scarcely understood how maternal nutrient environment affect the performance and response of offspring through transgenerational effect. Here we st...

Many economists argue that high mortality is a major restraint on human capital accumulation and, in turn, growth. A short time horizon makes a person less likely to invest. Therefore, having a lower life expectancy reduces the incentive to obtain schooling. However, there is controversy over whether this theoretical effect is empirically important. Most previous research designs have been unab...

The expression of infectious disease is increasingly recognized to be impacted by maternal effects, where the environmental conditions experienced by mothers alter resistance to infection in offspring, independent of heritability. Here, we studied how maternal effects (high or low food availability to mothers) mediated the resistance of the crustacean Daphnia magna to its bacterial parasite Pas...

introduction: compared to other developed countries, the maternal mortality rate is much higher in iran.  bleeding, infection and gestational hypertension are the main causes of maternal mortality and abortion is a major cause of bleeding and infection. the objective of this study was to determine the incidence of abortion and its effect on maternal mortality. materials and methods: this descri...

influence of maternal and sire-generation interaction effects on day-old chick' weight was investigated in two commercial broiler sire and dam lines, and in mazandaran native fowls. the data were analysed through restricted maximum likelihood (reml) procedures, using asreml software. ten different animal models were implemented and compared with likelihood ratio test. all models consisted ...

Maternal education is one of the strongest determinants of infant survival in developing countries, however, questions remain regarding the extent to which its effects vary as a function of contextual variables. In this study, a multi-level interactive model is used to assess whether the protective effect of maternal education on the risk of infant diarrhea is modified by three aspects of the m...
