Background . Bitter melon ( Momordica charantia L.) is a vegetable and medicinal crop new for Russia. Its high heat demand the main factor limiting possibilities of its cultivation in temperate continental climate. Evaluation selection more cold-resistant accessions required breeding cultivars expanding production. Previously obtained data attest to possibility assessing cold hardiness mature m...

Polyethylene glycol (PEG) electrolyte solution can induce potentially fatal complications when used as a lavage in preoperative bowel preparation. A 60-year-old man with carcinoma of the esophagogastric junction had a Mallory-Weiss tear after bowel preparation with PEG. He was successfully resuscitated, first with balanced salt solution then by transfusion. The literature on the subject is revi...

Brighter SERRS nanotags ideal for improved SERRS imaging were prepared by the controlled addition of electrolyte producing a dimer enriched solution, which was incubated with a Raman reporter before being stabilised by a polyethylene glycol (PEG) shell.

We investigated the role that manganese superoxide dismutase (MnSOD), an important antioxidant enzyme, may play in the drought tolerance of rice. MnSOD from pea (Pisum sativum) under the control of an oxidative stress-inducible SWPA2 promoter was introduced into chloroplasts of rice (Oryza sativa) by Agrobacterium-mediated transformation to develop drought-tolerant rice plants. Functional expre...

To study the effects of halopriming and hydropriming in overcoming salt and drought stress in corn (Zea mays L.),two experiments were separately conducted at Shahrood University of Technology. Seed treatments consisted ofcontrol (untreated seeds), soaking in distilled water for 32 h (hydropriming), and soaking in 50 mmol solution ofCaCl2 for 16 h (halopriming). Germination and early seedling gr...

meloxicam is a poorly water soluble non steroidal anti-inflammatory drug and antipyretic agent. the aim of the present work was to investigate the effect of different types of carriers on in vitro dissolution of meloxicam. meloxicam solid dispersions were prepared by physical mixing, co-grinding and solvent evaporation methods with polyethylene glycol (peg) 6000. the effect of solubilization by...

Germination characteristics, early seedling growth and seed metabolic efficiency of four wheat genotypes (BARI Gom 28, BARI 29, BAW 1177 ESWYT 29) were evaluated under 15% polyethylene glycol (PEG-6000) induced osmotic stress (-3 bar). characteristics (germination rate, co-efficient germination vigor index), shoot root length, dry weight, decreased by PEG than control treatment. But the degree ...

Doxazosin mesylate (DXM) sustained release pellets were prepared by an extrusion-spheronization and fluid-bed coating technique. The core pellets containing DXM were prepared by extrusion-spheronization technique, and coated by a fluid-bed coater to control the release of DXM. The factors affecting to properties of pellets, such as diluent content, type and coating level of coating agents and p...

Vitamin E D-alpha-tocopheryl polyethylene glycol succinate (TPGS) and polyethylene glycol are common excipients used in both preclinical and commercial formulations. In this paper, the phase diagrams of TPGS and polyethylene glycol 400 (PEG 400) in the presence of either water or ethanol were constructed. The effect of water and ethanol on the cloud point temperature of TPGS-PEG 400 mixtures wa...

aqueous two-phase systems (atps) have  emerged as a powerful extraction method for the downstream processing of bio-molecules. the aim of this work was to investigate the possibility of utilizing atps for the separation of recombinant bacillus sphaericus phenylalanine dehydrogenase (phedh). polyethylene glycol (peg) and ammonium sulfate systems were selected for our experiment. the effect of di...
