Abstract (sommario):

Conventional suppositories of tolmetin sodium were prepared by using two different types of Witepsol as an oily base and two different ratios of polyethylene glycol 400: polyethylene glycol 4000 as an water-soluble base. In addition, sustained- release suppositories were prepared by adding Eudragit L-100 ta the suppositories. The effects of the suppository base and the ratios of the polyethylene glycol 400: polyethylene glycols 4000 on the in vitro release characteristics were investigated. The release rate of tolmetin sodium from the conventional suppositories prepared with polyethylene glyco

Abstract (sommario):

Extraction of Eu3+ and Ce3+ microamounts from 0.1-0.4M perchloric acid by the nitrobenzene solution of dicarbolide H+[Co(C2B9H11)2]- in the presence of polyethylene glycols (Mr = 200, 300, 400) has been studied. The equilibrium data and the typical maxima on the dependence of the metal distribution ratio on the total analytical concentration of polyethylene glycol in the system can be explained assuming that the species ML3+org, ML3+2org, ML3+3org, MLH2+-1org, and HL+org (where M3+ = Eu3+, Ce3+; L = polyethylene glycol) are extracted into the organic phase.

The development of anti-icing, anti-frosting transparent plates is important for many reasons, such as poor visibility through the ice-covered windshields of vehicles. We have fabricated new glass surfaces coated with polypeptides which mimic a part of winter flounder antifreeze protein. We adopted glutaraldehyde and polyethylene glycol as linkers between these polypeptides and silane coupling agents applied to the glass surfaces. We have measured the contact angle, the temperature of water droplets on the cooling surfaces, and the frost weight. In addition, we have conducted surface roughness

Abstract (sommario):

Notably, antibiofouling is an important and predominant technique adopted to improve the surfaces of biomaterials. In this study, polyethylene glycol-grafted polyethylene glycols bearing azidophenyl groups were synthesized and immobilized on polystyrene surfaces via photoirradiation. The prepared polymers were found to be highly soluble in water, and photoimmobilization with fluorescent proteins was confirmed based on micropatterning using a photomask. These polymers suppressed nonspecific interactions between proteins and cells on the substrate. Considering that photoimmobilization can be ado

Abstract (sommario):

Objective: The rationale of the current research work was to formulate and evaluate fast-dissolving tablets of doxazosin mesylate with minimum disintegration time and improved dissolution efficiency using solid dispersion method.Methods: Solid dispersions of doxazosin mesylate and polyethylene glycol 8000 in different ratios were prepared using the kneading method. The prepared solid dispersions were subjected to drug interaction and dissolution studies to select the effective solid dispersion for the formulation of fast-dissolving tablets. Fast dissolving tablets containing drug-polyethylene

Abstract (sommario):

Introduction: The use of polyethylene glycol-based solutions is the gold standard for bowel preparation for colonoscopy. However, polyethylene glycol use might be associated with the risk of acute kidney injury. We aim to find out acute kidney injury and risk factors associated with the development of acute kidney injury in patients using polyethylene glycol for colonoscopy.Materials and Methods: This was an observational study conducted in the Department of Nephrology and Gastroenterology, Bir hospital. Patients who underwent colonoscopy using polyethylene glycol were included in the study an

Abstract (sommario):

Introduction. Macroprolactinemia is one of the common causes of hyperprolactinemia, especially in cases where standard routine commercial immunometric assays are used for prolactin level measurement. Two forms of prolactin, inactive dimeric prolactin (50 - 60 kDa) and a low-activity tetramer (molecular weight above 150 kDa), contribute to this condition. The relatively low incidence of symptoms in macroprolactinemia patients has necessitated a relatively simple method to detect large, biologically inactive prolactin molecules, such as polyethylene glycol precipitation method. The aim of this s

Abstract (sommario):

Polyethylene glycol used as coating materials because it resist to protein adsorption and bacterial adhesion. Polyethylene glycol and crosslinked polyethylene glycol & polyethylene glycol chitosan conjugate used for coating glass implants. Fourier transform infrared spectroscopy (FTIR) analysis showed proper crosslinking in crosslinked polyethylene glycol but in polyethylene glycol & chitosan conjugate no reaction takes place. Scanned Electron Microscope (SEM) used for study of surface morphology. Polyethylene glycol & chitosan conjugate have smoother surface than pure polyethylene

Abstract (sommario):

Using the Anton- Paar DSA 5000 M, the density and sound speed of polyethylene glycols (polyethylene glycol 400; polyethylene glycol 4000) in an entire range of concentrations (0.07, 0.08, and 0.09) mol.kg-1 aqueous solutions of vitamin B3 (niacin) were measured at constant experimental pressure 0.1 MPa and temperature ranges (288.15 K, 298.15 K, 308.15 K, and 318.15 K). These experimental results were used to measure acoustic and thermodynamic parameters such as acoustic impedance, adiabatic compressibility, intermolecular free length, Wada's constant, Rao's constant, and Vander Waal's constan
