introduction:this study examined the effects of administration of subcutaneous β-estradiol on ptsd-like symptoms (the enhanced conditioned fear response, cfr) that induced by a single-prolonged stress (sps) and shock in rats. adult male wistar rats were exposed to sps procedure: restraint for 2 h, forced swim for 20 min, and ether anesthesia. then the rats were placed in fear conditioning syste...

background: polycyclic aromatic hydrocarbons (pahs) such as naphthalene (nap) are organic pollutants that have spread widely in littoral marine ecosystems. we aimed to study the effect of acute and prolonged exposure to naphthalene (nap) on plasma cortisol and thyroid levels in mature and immature liza klunzingeri mulet. methods: in acute stress experiment, the treatment group received 2μl g-1 ...

This study was done to evaluate transvaginal ultrasonographic measurement of cervical length at 20 to 24 weeks and 37 weeks as a predictor of prolonged pregnancy (defined as a pregnancy that extended beyond 41+2 weeks of gestation [289 days]) in nulliparous women. This prospective observational study enrolled 149 consecutive nulliparous women with singleton gestation at 37 weeks. Cervical lengt...

Scant scientific attention has been given to the abundance and distribution of marine biota in the face of the lower sea level, and steeper latitudinal gradient in climate, during the ice-age conditions that have dominated the past million years. Here we examine the glacial persistence of Atlantic cod (Gadus morhua) populations using two ecological-niche-models (ENM) and the first broad synthes...

OBJECTIVES Labor induction in post-term pregnancy is considered as a conventional process of mothers' care. Shiatsu technique is one of the complementary methods which use for post-term pregnancy induction. Therefore, the researchers decided to examine the effect of Shiatsu technique on the induction of post-term pregnancy. MATERIALS & METHODS This is a randomized control trials which conduct...

We obtained data recorded in the Danish medical birth registry on all women with a prolonged pregnancy in the first delivery and in a subsequent delivery, during 1980-94, and a 5% sample of all women with two or more pregnancies recorded in the period 1980-92 (only the first two deliveries were used for analysis). The information on gestational age in the registry was obtained from birth record...

Balancing the risks of prolonged gestation against those of induced labour is difficult. Risks to the fetus increase slightly after 42 weeks' gestation but women having labour induced are more likely to have instrumental deliveries or babies with low Apgar scores. Since many women are now expressing a preference for minimal interference in childbirth the most acceptable management of post-term ...
