The effects of chronic (14 day) intracerebroventricular infusion of various amounts of ovine corticotropin-releasing factor (oCRF) on the circadian blood corticosterone rhythm in male rats were examined. Control (saline-infused) rats showed distinct blood corticosterone rhythms over 48 h with nadirs at 0900 h and peaks at 2100 h on days 6-7 and 13-14. oCRF at 3 pmol/h did not affect the circadi...
Glutamate induces excitotoxic damage to hippocampal pyramidal neurons in Status Epilepticus (SE) and epilepsy. In this study, we investigated time course of dysregulation of calcium homeostasis at various intervals after an episode of SE in acutely isolated CA1hippocampal pyramidal. For this purpose, male Sprague-Dawley rats (200 g) were subjected to pilocarpine-induced SE. The SE was blocked a...
This problem belongs to an ever-increasing list of problems known to be unsolvable from the (usual) axioms of set theory. However, some of these problems have now been solved. But what does this actually mean? Could the Continuum Hypothesis be similarly solved? These questions are the subject of this article, and the discussion will involve ingredients from many of the current areas of set theo...
The rising human population, particularly in the developing countries, and the attendant socioeconomic effects necessitates the need for its effective regulation. This study aims at exploring the contraceptive efficacy of the fruit extract of Xylopia aethiopica (Dunal) A Rich, a plant with wide ethnomedicinal, pharmacological and social values, in combating this public health challenge. Forty e...
conclusions the pattern of pretreatment with o2 could change this potential and highly protective strategy against cp-induced nephropathy to an ineffective or even mildly deteriorating one. therefore, o2 administration before cp injection to patients with cancer, for therapeutic purposes or as a preconditioning approach, should be performed and investigated with caution until exact effects of d...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Objective The aim of this study was to assess which characteristics and results of vaginal examination are predictive for delivery within 7 days, in women with threatened preterm labor after initial treatment. Study Design A secondary analysis of a randomized controlled trial on maintenance nifedipine includes women who remained undelivered after threatened preterm labor for 48 hours. We develo...
A biventricular bypass type total artificial heart (BVB-TAH) utilizing two pusher-plate pumps was developed and implanted in a sheep for 48 days with excellent results. A Hall effect sensor was utilized to operate each pump independently with a full stroke at variable rates (VR). With this system, the animal's hemodynamics was kept physiologically, and all metabolic parameters except hemoglobin...
The objective of this study was to determine the therapeutic and residual efficacy of a topically applied combination of cyphenothrin (40%) and pyriproxyfen (2%) against the tick Haemaphysalis elliptica and the flea Ctenocephalides felis on dogs. Twelve dogs were infested with 50 ticks 2 days before they were treated and with approximately 100 fleas 6 days before treatment and again 2 days befo...
