A previous decision analysis models for two strategic choices for trial of labor or repeated cesarean after prior cesarean concluded that the degree of wish for an additional future pregnancy appeared to be a major determinant for choice between the two strategic options. We had extended the analysis model to stillbirth and hypoxic-ischemic encephalopathy(More)
BACKGROUND West Nile Virus (WNV) is endemic in Israel and a significant level of antibodies is present in the population due to natural exposure. Anecdotal cases suggested that the presence of anti-WNV antibodies in intravenous immunoglobulin (IVIG) from Israeli donors (IVIG-IL) assisted the recovery of patients with severe WNV infection. METHODS To(More)
Blind mole-rats (Spalax ehrenbergi) are solitary aggressive subterranean rodents. They inhabit individual territories, comprised of branched tunnels. Each such tunnel system is completely separate from that of any neighboring mole-rat. Although intraspecific encounters between neighbors are infrequent, when they do occur, they may result in the injury or(More)
This study investigated the sexual attraction of female blind mole rats to four groups of male mole rats: (a) intact males raised in captivity; (b) intact males trapped in the field; (c) captive males injected with testosterone; (d) captive castrated males. In the first part we measured blood testosterone, androstenedione, and dihydrotestosterone (DHT)(More)
Diabetes in streptozotocin-treated rats is associated with alterations in various neuroendocrine systems, including endogenous opioids. These changes are suggested to be responsible for the significant reduction in serum prolactin (PRL) response to a brief restraint stress in diabetic male rats, as compared with normoglycemic controls. The present study(More)
The blind mole rat is a seasonally breeding fossorial rodent that is perceptionally blind. This study examines the effect of photoperiod on the morphology and histology of the male mole rat reproductive system, three groups of male mole rats were maintained in the laboratory under short day (SD) conditions (9L: 15D); long day (LD) conditions (15L:9D); and(More)
BACKGROUND High sensitivity C-reactive protein (hsCRP) has become a routine assessment tool to discriminate between patients at low, intermediate or high risk for cardiovascular events using the threshold values of 1 and 3mg/L, respectively. Over the past years, several studies have proposed the wide range C-reactive protein (wrCRP) as an alternative to the(More)
The effect of Naltrexone (Nalt), a specific opiate receptor blocker, on LH secretion was studied at frequent intervals during the first hour following treatment. Nalt was injected i.v. by one bolus (1 mg/rat) to diabetic and normoglycemic rats. Blood samples (0.8 ml) were withdrawn at short intervals after injection, through an indwelling cannula. The(More)
Previous studies with naltrexone (Nalt), a "long-lasting" opioid antagonist, demonstrated a rapid increase in luteinizing hormone (LH) secretion which gradually declined, reaching baseline values after 1 hr. A second Nalt challenge, 120 min later, caused only a blunted response. This poor reaction has been shown in this study not to be due to lack of(More)
