Digital printing waste paper fiber/nanocrystalline cellulose/poly(lactic acid) composites, modified through γ-methacryloxy propyl trimethoxy silane (KH570), isopropyl tri(dioctylpyrophosphate) titanate, sodium hydroxide, polyethylene glycol 6000 (PEG6000), and a composite coupling agent (KH570/PEG6000), were fabricated by melt blending injection molding, the effects of different modifiers on pr...

Highly stable niosomes are prepared and investigated in Tween80/PEG6000/Span80/H2O system. The mean radius of the niosomes is 0.15-0.2 microm. The contents of PEG6000 and Span80 and the system temperature affect the size and the stability of the niosome. A certain Span80 can remarkably improve the stability. The niosome is provided distinctly with the hydrotrope-solubilization action to the hyd...

BACKGROUND Drought is a common stress limiting crops growth and productivities worldwide. Water deficit may increase cellular membrane permeability, resulting in K outflow. Internal K starvation may disorder plant metabolism and limit plant growth. However, it is seldom reported about the effects of external K on drought tolerance of contrasting wheat cultivars. METHODOLOGY/PRINCIPAL FINDINGS...

Glipizide (GZ) is an oral blood-glucose-lowering drug of the sulfonylurea class characterized by its poor aqueous solubility. Aiming for the production of GZ tablets with rapid onset of action followed by prolonged effect; GZPolyethylene glycol (PEG 4000 and 6000) solid dispersions with different ratios, (using melting and solvent evaporation method), as well as, coprecipitate containing GZ wit...

−Aqueous two-phase system (ATPS) was applied for extraction bioconversion of xylan by xylanase from Trichoderma viride. Phase diagrams for poly (ethylene glycol) (PEG) and sodium citrate were determined at room temperature. The ATPS composed of 12.99% (w/w) PEG6000 and 12.09% (w/w) sodium citrate was favorable for partition of xylanase and used for extraction bioconversion of xylan. Batch hydro...

Abscisic acid (ABA) catabolism is one of the determinants of endogenous ABA levels affecting numerous aspects of plant growth and abiotic-stress responses. The major ABA catabolic pathway is triggered by ABA 8'-hydroxylation catalysed by ABA 8'-hydroxylase, the cytochrome P450 CYP707A family. In this study, the full-length cDNAs of AhCYP707A1 and AhCYP707A2 were cloned and characterized from pe...

The aim of this study was to investigate the effect of different carriers on solubility and in vitro dissolution of poorly water soluble drug meloxicam (MLX). Solid dispersions with Polyethylene glycol-6000 (PEG6000), Poloxamer 188 (Plx188), Poloxamer 407 (Plx407) and inclusion complexes (ICs) with β cyclodextrin (β-CD) were prepared by different methods in three different weight ratios. All SD...

In this study, we conducted the first isobaric tags for relative and absolute quantitation (isobaric tags for relative and absolute quantitation (iTRAQ))-based comparative proteomic analysis of ramie plantlets after 0 (minor drought stress), 24 (moderate drought stress), and 72 h (severe drought stress) of treatment with 15% (w/v) poly (ethylene glycol)6000 (PEG6000) to simulate drought stress....

BACKGROUND Drought is the most important factor that limits rice production in drought-prone environments. Plant microRNAs (miRNAs) are involved in biotic and abiotic stress responses. Common wild rice (Oryza rufipogon Griff.) contains abundant drought-resistant genes, which provide an opportunity to explore these excellent resources as contributors to improve rice resistance, productivity, and...
