background: tubo-ovarian abscess as a serious complication of pelvic inflammatory disease is very uncommon in sexually inactive girls. case: we report a case of tubo-ovarian abscess in a 24-year-old sexually inactive girl with transverse vaginal septum who was presented with abdominal pain and a pelvic mass and without prior surgical history and no evidences of appendicitis, inflammatory bowel ...

Multiple occurrences of liquefaction in recent earthquake events revealed the importance studying reliquefaction characteristics sandy soils. However, there is a lack knowledge determining dynamic properties reliquefied Through series hollow cylinder torsional shear tests, this paper presents first-hand experimental study to investigate modulus reduction and damping Toyoura sand under integrate...

PURPOSE To determine the measurement reliability of CorVis ST, a dynamic Scheimpflug analyser, in virgin and post-photorefractive keratectomy (PRK) eyes and compare the results between these two groups. METHODS Forty virgin eyes and 42 post-PRK eyes underwent CorVis ST measurements performed by two technicians. Repeatability was evaluated by comparing three consecutive measurements by technic...

BACKGROUND Mating decreases female receptivity and terminates sex pheromone production in moths. Although significant progress has been made in elucidating the mating-regulated inactivation of pheromone biosynthesis-activating neuropeptide (PBAN) secretion, little is known about the mating induced gene expression profiles in pheromone glands (PGs). In this study, the associated genes involved i...

Studies were conducted on the physiological mode of action and mode of perception of a queen pheromone that inhibits dealation (wing-shedding) and ovary development in virgin queens of the fire ant Solenopsis inuicta. Winged virgin queens were removed from the pheromonal signal (queen) to compare the response time for dealation, a behavioral response, and ovary development, a physiological resp...

Endogenous opioid regulation of neurohypophysial and hypothalamo-pituitary-adrenal (HPA) axis hormone secretion in response to forced swimming (90 s in deep water at 19 degrees C) was investigated in virgin and 21-day-pregnant rats. There was no difference in basal plasma oxytocin concentrations between pregnant and virgin rats, but the opioid antagonist, naloxone, increased basal oxytocin secr...

Pregnancy-induced hypertension has been suggested to be mediated by several mechanisms, including reduced nitric oxide (NO) synthesis. In this study, the effects of chronic treatment with the NO synthase inhibitor NG-nitro-L-arginine methyl ester (L-NAME) on blood pressure and the underlying changes in vascular reactivity were investigated in virgin and late-pregnancy Sprague-Dawley rats. The s...

Incorporation of 32p into RNA and DNA fractions of mammary and tumor tissue was studied in virgin C3H mice, which are susceptible to the development of breast cancer. Virgin C57BL mice, which are resistant to the development of breast cancer, were the controls. Virgin C3H and C57BL mice, 4 and a months old, and tumor-bearing C3H mice were used as the experimental groups. The incorporation of 32...

Greece is ranked third after Spain and Italy in virgin olive oil production. The number of Greek olive cultivars-excluding clonal selections-is greater than 40; however, more than 90% of the acreage is cultivated with 20 cultivars, adapted to a wide range of environmental conditions. Greek virgin olive oils, produced mainly with traditional, non-intensive cultivation practices, are mostly of ex...

BACKGROUND Most human demographic data, particularly those on natural fertility populations, find no relationship or even a positive association between fertility and longevity. The present study aims to ascertain whether there is a trade-off between fertility and longevity in the mouse model. METHODS The study was focused on the first litter produced by 10- to 14-wk-old hybrid (C57BL/6JIco f...
