BACKGROUND Neonate with abnormal weight is at risk of increased mortality and morbidity. Many factors affect pregnancy outcome. Because of the importance and vital role in birth weight, in this study, some of the factors associated with birth weight in a sample of Iranians neonates were investigated. MATERIALS AND METHODS In this cross-sectional study, 245 newborns in a sample of Iranians neo...

We determine fixation probabilities in a model of two competing types with density dependence. The model is defined as a two-dimensional birth-and-death process with density-independent death rates, and birth rates that are a linearly decreasing function of total population density. We treat the 'quasi-neutral case' where both types have the same equilibrium population densities. This condition...

In a first part, we prove a Lyapunov-type criterion for the ξ1-positive recurrence of absorbed birth and death processes and provide new results on the domain of attraction of the minimal quasi-stationary distribution. In a second part, we study the ergodicity and the convergence of a Fleming-Viot type particle system whose particles evolve independently as a birth and death process and jump on...

Doppler ultrasound is widely used in obstetrics. However, the biological effects of high energy from ultrasonography have not been clearly revealed. Animal studies shown negative on fetus, but humans are limited. The aim this study to evaluate effect early pregnancy weeks (6-12 week) detect fetal cardiac activity outcomes (number births and abortions, type delivery, cesarean indications, birth ...

OBJECTIVE To examine the association between a history of type 2 diabetes and birth weight of offspring and grandchildren. DESIGN Prospective observational study. Diabetic status, as reported by mothers (F1 generation) was collected on grandparents (F0) of babies (F2) born to mothers (F1) who participated in a study of maternal and child health. Associations between risk of grandparental diab...

Background: In 1967 Barker first established the concept that a harmful intrauterine environment can have lifelong effects and contribute to adult onset disease. This Barker hypothesis, as it is now referred to, has since been cited in numerous disease associations including the well established correlation between low birth weight and adult onset type 2 diabetes. Studies have shown that full t...
