Polyethylene glycol (PEG) was genetically incorporated into a polypeptide. Stop-anticodon-containing tRNAs were acylated with PEG-containing amino acids and were then translated into polypeptides corresponding to DNA sequences containing the stop codons. The molecular weights of the PEG used were 170, 500, 700, 1000, and 2000 Da, and the translation was confirmed by mass spectrometry. The PEG i...

Diazepam possesses potent anti-epileptic, anti-anxiety activity and also indicated for the treatment of insomnia. It is very slightly soluble in water and shows poor dissolution. Presently, liquisolid compact technique is found to be used extensively as one of the successful tool to enhance the solubility and dissolution of various poorly soluble drugs. The principle focus of this study is to f...

Potassium tribromide wrapped around polyethylene glycol ({K+PEG400}Br3-) was easily prepared by two step reaction of PEG400 with KBr followed by the addition of molecular bromine to give PEG embedded potassium tribromide as a dark viscous oil. The synthesized material was found to be an efficient, cost effective, environmentally benig...

The effects of polyethylene glycol (PEG) 200 administered by gavage on electrolyte and water excretion were investigated in the rat. PEG 200 led, in intact rats, to dose-related increased drinking and to diuresis. In the first 2 h after PEG 200 administration, water consumption in intact rats exceeded urine output. PEG 200 enhanced the excretion of both sodium and potassium, but the sodium excr...

The in vitro digestibility of dry matter (IVDMD) and of nitrogen (IVND) was measured on six leguminous tropical shrubs and the grass Panicum maximum, in the presence and absence of polyethylene glycol (PEG) 4000. The PEG was spiked with C-labelled PEG 4000 so that PEG remaining in the residues after digestion could be calculated. This was subtracted from the residues to enable a corrected IVDMD...

The physicochemical properties of Doxorubicin–PEG–FOL and Daunorubicin-PEG-FOL ( Doxorubicin and Daunorubicin conjugated to polyethylene glycol–folate nanoparticles) have been estimated using Density functional Theory (DFT) and Hartree Fock(HF) calculations.In this report some geometrical parameters of Doxorubicin-PEG-FOL complex of the conjugated complex and Daunorubicin–PEG–FOL complex of the...

Background: A major challenge in downstream processing is the separation and purification of a target biomolecule from the fermentation broth which is a cocktail of various biomolecules as impurities. Aqueous two phase system (ATPS) can address this issue to a great extent so that the separation and partial purification of a target biomolecule can be integrated into a single step. In the food i...

Front Cover: In article number 2000754, Susan M. Kelleher and co-workers outline an accessible scalable method for polyethylene glycol (PEG)-tapered nanopillar array production. Photopolymerisation of acrylateterminated polypropylene (PPG) PEG monomeric/photoinitiator cocktails is utilised to cast high fidelity replicas silicon arrays. this way, rapid prototyping polymeric nanostructured surfac...

The effect of coating silica with polyethylene glycol on the adsorption iron and phosphate ions in industrial wastewater was investigated. Variable factors were temperature time coating, PEG concentration, to ratio. Infrared spectroscopy scanning electron microscopy used evaluate chemical structure morphology PEG-coated silica. Optimum removal efficiency obtained using a 50°C, 15 min, concentra...

Silicon is known to ameliorate the deleterious effects of drought on plant growth. We evaluated growth of wheat (Triticum aestivum L. CV. Chamran) under Water-Deficit Stress Induced by Polyethylene Glycol as affected by Si application. In this article, the effects of Si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (RWC), electrol...
