NMDA receptor antagonists block conditioned fear extinction when injected systemically and also when infused directly into the amygdala. Here we evaluate the ability of D-cycloserine (DCS), a partial agonist at the strychnine-insensitive glycine-recognition site on the NMDA receptor complex, to facilitate conditioned fear extinction after systemic administration or intra-amygdala infusions. Rat...

Four phosphorus fertilizer rates (0, 30, 60, and 90 kg ha-1) were evaluated for the nine common vetches (Vicia sativa) varieties ,Clima, Hanka, Mikaela, Lujiliana, Marrianum, Mery, Beybi, Nigra, Namoi. Experiments was conducted during winter season of 2019-2020 in Sulaimani governorate at Qlyasan locations. The experiment designed Factorial CRBD (Randomized Complete Block Design) with three rep...

The objective of this study was to evaluate the effect an early application potassium (K) fertilizer on pearl millet (Pennisetum glaucum L.) grown during fall/winter performance maize (Zea mays silage in succession. Using a randomized block design, harvest, plots were composed and six doses K (0, 30, 60, 90, 120 150 kg K2O ha-1) as muriate potash (57% K2O) addition fallow. In summer cultivation...

Incorporation of biochar to agriculture field has the potential to be a primary factor in maintaining soil fertility and productivity particularly in nitrogen and organic matter limiting environments however, clear experimental evidence to support this views still lacking. The current experiments were carried out to evaluate the effect of different organic (biochar and FYM) and inorganic amendm...

Waterfowl frequently acquire high-energy agricultural seeds in harvested and unharvested croplands during migration and winter. Estimates of agricultural seed biomass in harvested and unharvested corn, soybean, and grain sorghum fields do not exist or are outdated for the southeastern United States. Therefore, we estimated seed biomass in 105 harvested and 59 unharvested corn, soybean, and grai...

The current study investigates the dissipation kinetics of two imidacloprid (IMI) nanoformulations (entitled: Nano-IMI and Nano-IMI/TiO2) on common bean (Phaseolus vulgaris) seeds under field conditions and compares them with 35% Suspension Concentrate (SC) commercial formulation. To do so, it sprays P. vulgaris plants at 30 and 60 g/ha within green bean stage, sampling them during the 14-day p...

to evaluate the effect of humic acid and phosphorus on the quantity and quality of marigold yield an experiment was conducted at research field of islamic azad university, mashhad branch, mashhad, iran, in cropping season 2010-2011. the experiment was in split plot based on randomized complete block design, with four replications. the main plots were humic acid in four levels (0, 5, 10 and 15 k...

The effects of nitrogen (N) addition on productive and physiological traits of Triticumdicoccum were assessed under two N levels (0, unfertilized, and 90 kg N ha−1) in fieldconditions, in two growing seasons. In the study case, the N supply (90 kg N ha−1) was appliedin three-split applications (20% at pre-plant stage, 40% at tillering stage, 40% at stemelongation). In unfertilized conditions, t...

The formation and persistence of methylatedpurines was determinedin mice that receiveda singles.c. Injec tion of 1,2-[14Cjdimethylhydrazine (15 mg/kg) and were allowed to survive for 12 or 60 hr. In mice with a low susceptibilityto dlmethylhydrazine-lnducedcolon card nogenesis(C57BL/Ha), concentrationsof 7-methylguan inc and 06-methylguanlnein DNA of colon, ileum, and kidney were 40 to 60% less...
