Durum wheat is the most widely grown cereal in Tunisia, but its production threatened by drought, which exacerbated climate change. This study aimed to identify drought-tolerant durum genotypes from five modern varieties and six landraces a multi-environment trial at two sites (Kef Siliana, Tunisia) during three growing seasons under rainfed irrigated conditions. Six drought tolerance indices (...

1. Toluene (TOL) is widely used in industry. Occupational exposure to TOL is commonly assessed using TOL in blood, hippuric acid and ortho-cresol. Levels of these biomarkers may depend on factors potentially interfering with TOL biotransformation, such as the presence of other solvents in the workplace. Mercapturic acids (MAs) could be an alternative to the "traditional" TOL biomarkers. 2. This...

responses of twenty chickpea genotypes to drought stress were evaluated in the farm of college of agricultutre, razi university, kermanshah, iran in 2006-2007. the experiment was carried out in randomized complete block design with three replications under two water stress and non-stress conditions. the results showed significant differences among the genotypes for most of the traits. maximum y...

BACKGROUND The purpose of this study was to evaluate collagen deposition, mRNA collagen synthesis and TGF-beta expression in the lung tissue in an experimental model of scleroderma after collagen V-induced nasal tolerance. METHODS Female New Zealand rabbits (N = 12) were immunized with 1 mg/ml of collagen V in Freund's adjuvant (IM). After 150 days, six immunized animals were tolerated by nas...

BACKGROUND Immunotherapy inhibits basophil histamine release, but the assay is cumbersome, and no one has studied the effects of immunotherapy withdrawal. OBJECTIVE Intracellular fluorochrome-labeled diamine oxidase (DAO) was used as a novel functional readout of basophil histamine release after immunotherapy. Results were compared with conventional basophil surface expression of activation m...

A series of colicin-tolerant (tol) mutants of Escherichia coli K-12, which adsorbed colicins but were not killed by them, were isolated and studied genetically and physiologically. Three major classes of mutants were found: tol II, tolerant to colicins A, E1, E2, E3, and K; tol III, tolerant to A, E2, E3, and K; and tol VIII, tolerant to E1 only. The sites of tol II and tol III mutations mapped...

to study drought resistance indices of eight potato cultivars and to determine the most tolerant variety, two experiments were conducted in the form of complete randomized block design with three replications (stress and non-stress conditions) in 2002. seven indices, ssi, tol, sti, msti, gmp, tol , and mp were used to determine tolerant varieties. it was found that mp, sti, gmp, and msti were a...

OBJECTIVE The study aimed to evaluate the pre-treatment and post-treatment oxidant capacity, antioxidant capacity and S100B protein levels in cases of diabetic ketoacidosis (DKA). METHODS The study included 49 pediatric patients diagnosed with DKA and a control group comprising 49 healthy children. Blood samples were obtained after confirmation of the DKA diagnosis and also after treatment. S...

introduction of a suitable vetch as winter crop in cold drylands of iran is highly important. line vp-2670 with origin of turkey was selected from icarda nursery during 2002 and was evaluated along with other selected lines and local checks over nine years in different stations and on-farm conditions. vp-2670 with mean 3500 kgha-1 dry biomass over environments, high stability and protein conten...

Introduction Toltrazuril (Tol) is used to prevent and combat coccidiosis. However, its low aqueous solubility and poor oral bioavailability limit clinical application. Methods To overcome the shortcomings, toltrazuril-hydroxypropyl-β-cyclodextrin inclusion complex (Tol-HP-β-CD) was prepared and characterized. The comparative plasma disposition kinetics of Tol was analyzed after a single orall...
