in this study proline content and activity of catalase (cat), and ascorbate peroxidase (apx) and level of lipid peroxidation in terms of malondialdehyde (mda) content were measured in transgenic tobacco (nicotiana tabacum cv. wisconsin), over expressing a δ-1-pyrroline-5-carboxylate synthase (p5cs) gene, and non transgenic plants as control. drought stress was applied using polyethylene glycol ...

The article presents a comparative description of the effect metabolically active substances and their compositions on individual physiological biochemical parameters soft wheat in drought conditions. study involved use 7 options for seed treatment: control (untreated seeds + distilled water); vitamin E solution (10-8M) - E; ubiquinone-10 Q; methionine (0.001%) M; paraoxybenzoic acid (PОBA) P; ...

The aim of the study was to assess the role of salicylic acid (SA) and abscisic acid (ABA) in osmotic stress tolerance of wheat seedlings. This was accomplished by determining the impact of the acids applied exogenously on seedlings grown under osmotic stress in hydroponics. The investigation was unique in its comprehensiveness, examining changes under osmotic stress and other conditions, and t...

We aimed to develop a high-throughput screening (HTS) system for preliminary predictions of human skin permeability by using an artificial membrane that can mimic the permeation behaviour of lipophilic and hydrophilic compounds across the human skin. In this study, we synthesized a copolymer containing poly(dimethylsiloxane) (PDMS) and poly(ethylene glycol) (PEG) 6000 and impregnated it onto a ...

The early stages of quinoa germination are sensitive to drought stress. For this purpose, a study entitled the effect selenium in different concentrations on characteristics and some antioxidant enzymes under stress conditions with polyethylene glycol (PEG 6000) was investigated. first experimental factor seed priming (from two sources: sodium selenate nanoparticles: SeNPs ? 33.4 nm) at 0.5, 1....

The 45-days-old seedlings of drought resistant (N-22, CR143-2-2) and susceptible rice (Oryza sativa L.) genotypes (Panidhan, Pusa-169) were subjected to osmotic stress in PEG-6000 solution of -10 and -16 bar and the relative water content (RWC), proline content, and pyrroline-5-carboxylate synthetase (P5CS) activity and its P5CS expression were studied. A gradual decrease in RWC was observed in...

The aim of this study was to determine the effect drought on accumulation and tolerance energy willow (Salix viminalis L. var. ‘Gigantea’) copper (Cu) nickel (Ni) in context phytoremediation potential plant biomass production under adverse water conditions. Drought simulated with polyethylene glycol (PEG-6000. 5%), metals were added at a concentration 1 mM. Plants cultivated greenhouse conditio...

Water stress caused by drought affects the productivity of sugarcane crop. A breeding alternative is selection drought-tolerant cultivars. The objective this study was in vitro screening cultivars tolerant to water using polyethylene glycol (PEG) as a stressing agent. Cultivars (cv) Mex 69-290, CP 72-2086, 79-431 and MOTZMex 92-207 were subjected different concentrations PEG 6000 (0, 3, 6 9% w/...

Pharmaceutical availability of diazepam, oxazepam and nitrazepam from solid dispersions of PEG 6000 have been studied in comparison with corresponding physical mixtures and pure benzodiazepines. Selected derivatives of 1,4-benzodiazepin-2-one are poorly water soluble drugs. The aim of this work was to report the properties of diazepamand nitrazepam-PEG 6000 solid dispersions. Differential scann...

Pharmaceutical aviailability of diclofenac sodium from solid dispersions of PEG 6000 have been studied in comparison to those of the corresponding physical mixtures and pure diclofenac sodium. The diclofenac sodium is poorly water soluble drug. The properties of diclofenac sodium-PEG 6000 solid dispersions have been determined by the methods of differential scanning calorimetry (DSC), X-ray dif...
