UNLABELLED Recently, it was shown that D-cycloserine (DCS, a NMDA partial agonist) facilitated extinction of fear as well as cocaine conditioned place preference (CPP) in rats. METHODS The present study examined the effects of DCS (15 mg/kg i.p. and 30 mg/kg i.p.) on extinction and renewal of cocaine-induced CPP in C57bL/c mice. In parallel, we examined the effects of DCS on locomotor activit...

The regulatory mechanisms underlying bud breaking (scale leaf elongation) and flowering in the lateral flower buds of Japanese pear (Pyrus pyrifolia Nakai 'Kosui') are unknown. To more fully characterize these processes, we treated pear trees with different amounts of chilling initiated at different times. Chilling for ∼900 h at 6 °C always induced bud breaking (scale elongation in ≥70% lateral...

Drought stress is a major abiotic constraint limiting crop production world wide. In current study, we investigated the adverse effects of drought stress on growth, yield and endogenous phytohormones of soybean. Polyethylene glycol (PEG) solutions of elevated strength (8% & 16%) were used for drought stress induction. Drought stress period span for two weeks each at pre and post flowering growt...

increasing the water use efficiency in crop production is an important issue today. an experiment was conducted in 2009 in order to evaluate the corn reaction to partial root zone drying at fars province. treatments consisted of four irrigation levels (control, alternative furrow irrigation during whole season, alternative furrow irrigation until flowering then full irrigation and full irrigati...

A total of 135 measurements of polyfructoside clearance as a measure of glomerular filtration rate (GFR) were made in 39 infants of 25.5-33 weeks' gestation, birth weight 720-2000 g, between the ages of 0.5 and 33 days. GRF was related to postconceptional age and increased exponentially from geometric mean 0.59 ml/min at 26 weeks' postconceptional age to 1.40 ml/min at 33 weeks. GFR in the firs...

Article info: Received: 27 August 2014 Accepted: 13 November 2014 ABSTRACT Root biomass accumulation in spring and winter varieties and hybrids pea was recorded in field experiment in the Institute of Forage Crops, Pleven, Bulgaria (2011-2013). Spring (Shtambovyi and Pleven 4) and winter (Rosacrono and Pleven 10) varieties and their hybrids (Shtambovyi x Pleven 10 and Rosacrono х Pleven 4) (in ...

The expression and transport functions of organic anion transporters are modified in liver diseases, and therefore the vascular clearances of endogenous and exogenous organic anions that are taken up by these transporters have been used to assess liver diseases in patients. More recently, liver imaging with hepatobiliary contrast agents, tracers, and dyes that cross hepatocytes through the orga...

Researchers have several options when designing proteomics experiments. Primary among these are choices of experimental method, instrumentation and spectral interpretation software. To evaluate these choices on a proteome scale, we compared triplicate measurements of the yeast proteome by liquid chromatography tandem mass spectrometry (LC-MS/MS) using linear ion trap (LTQ) and hybrid quadrupole...

Three different ethanol solutions were sprayed onto Cabernet Sauvignon (Vitis vinifera L.) clusters during the ripening period: 2.5, 5 and 10% by volume in water. Controls were sprayed with water alone. Three different times of spraying were also tested: 8, 10 and 13 weeks post-flowering. One of the observed changes was a lower titratable acidity in grape samples at harvest, when the clusters w...

Genotype, environmental temperature, and agronomic management of parents influence seed yield in three-way cross hybrid maize production. The objective this research was to generate information on the production six hybrids their progenitors, adapted tropical lowlands. Data days to—and duration of—flowering, distance spike stigmas, five female single crosses male inbred lines were recorded for ...
