Long-term effects of stress during pregnancy on brain and behavior have been analyzed extensively in recent years. These effects include changes in emotional behavior, a reduction in learning capacity, and ability to generate long-term potentiation (LTP) in the offspring. In earlier studies, we and others have described a difference in ability to express LTP in dorsal and ventral sectors of the...

The effect of chronic nicotine treatment on chronic psychosocial stress-induced impairment of short-term memory and long-term potentiation (LTP) was determined. An "intruder" stress model was used to induce psychosocial stress for 4-6 wk, during which rats were injected with saline or nicotine (1 mg/kg s.c.) twice a day. The radial arm water maze memory task was used to test hippocampus-depende...

Term proximity is effective for many information retrieval (IR) research fields yet remains unexplored in blogosphere IR. The blogosphere is characterized by large amounts of noise, including incohesive, off-topic content and spam. Consequently, the classical bag-ofwords unigram IR models are not reliable enough to provide robust and effective retrieval performance. In this article, we propose ...

A 30-year-old white male underwent LASIK by another surgeon in July 1998 with a VISX STAR laser (VISX, Inc., Santa Clara, CA) and a Moria LSK microkeratome (Moria, Antony, France) to correct moderate myopia: -5.50 D sphere OD, -6.00 D sphere OS, and a BCVA of 20/20 OU. His preoperative corneal thicknesses were 548 and 555 μm OD and OS, respectively. The initial LASIK surgery resulted in an over...

Although post-term pregnancy is associated with an increased incidence of fetal distress, oligohydramnios, fetal macrosomia, fetal dysmaturity, and perinatal mortality, as many as 80% of post-term fetuses appear completely normal. The authors of this article discuss the three sub-groups of post-term pregnancies, and deal with the diagnosis and antepartum and intrapartum management of the condit...

Background Uterine rupture in a term pregnancy is an adverse and rare event with serious maternal and fetal consequences. The history of uterine septum resection is considered as a risk factor for uterine rupture. Women with such circumstances are thus recommended to be considered as having a high-risk pregnancy. Accordingly, their prenatal care should be implemented in shorter intervals during...
