Drought is considered one of the leading abiotic constraints to agricultural crop production globally. Present study was conducted assess effects different drought treatments (viz. Control, 10% PEG, and 20% PEG) on seed germination, germination indices, seedling traits, tolerance indices sesame. Our results showed that maximum reduction in studied parameters observed at higher PEG concentration...

In this study a 3-factor, 3-level Box-Behnken design was used to prepare optimized docetaxel (DTX) loaded pegylated poly lactide-co-glycolide (PEG-PLGA) NPs with polymer concentration (X1), drug concentration (X2) and ratio of the organic to aqueous solvent (X3) as the independent variables and particle size (Y1), poly dispersity index (PDI) (Y2) and drug loading (Y3) as the responses. The cyto...

Small-angle scattering studies generally indicate that the dimensions of unfolded single-domain proteins are independent (to within experimental uncertainty of a few percent) of denaturant concentration. In contrast, single-molecule FRET (smFRET) studies invariably suggest that protein unfolded states contract significantly as the denaturant concentration falls from high (∼6 M) to low (∼1 M). H...

We demonstrate that a microfabricated bump array can concentrate genomic-length DNA molecules efficiently at continuous, high flow velocities, up to 40 μm/s, if the single-molecule DNA globule has a sufficiently large shear modulus. Increase in the shear modulus is accomplished by compacting the DNA molecules to minimal coil size using polyethylene glycol (PEG) derived depletion forces. We map ...

The rapid-release mechanisms of standard extract from Ginkgo biloba leaf (EGb) in the polyethylene glycol (PEG) 6000 dispersions were investigated. The apparent equilibrium solubilities of the total flavone glycosides and the soluble solid materials of EGb increased linearly with the increasing concentrations of PEG 6000 solutions. In DSC curves, the peak, onset and endset temperatures of solid...

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...

The aim of the current study was to develop a nanostructured double-layer for hydrophobic molecules delivery system. developed consisted polyethylene glycol-based polymeric (PEG) followed by gelatin sub coating core containing sodium citrate. composition ratio PEG and amount were optimized using two-level fractional method. nanoparticles characterized AFM FT-IR techniques. size these nano capsu...

Using synchrotron-based small-angle X-ray scattering techniques, we demonstrate that poly(ethylene glycol)-functionalized gold nanoparticles (PEG-AuNPs) are assembled into close-packed structures include short-range order with face-centered cubic structure, where crystalline qualities varied by controlling the electrolyte concentration, pH, and temperature of suspensions. We show interpolymer c...

The effect of polyethylene glycol 400 (PEG) dissolved at various concentrations (0-40% v/v) in water, on the interfacial transport of methyl nicotinate across an aqueous-isopropyl myristate interface was investigated with a rotating diffusion cell. At four temperatures studied (20-37 °C), the presence of PEG decreased the rate of solute transfer both into and out of the organic phase in a conce...

the role of polymeric additives such as pvp and peg is studied with respect to the morphology of pes porous layer as a sublayer of nanofiltration composite membranes based on pes/pa. results show that by phase inversionprocess of quaternary systems comprised of four components of polymer/solvent/non-solvent/additive and the diffusion of intertwined polymers some changes occur in membrane morpho...
