Abstract Mixed matrix membranes (MMMs) have been widely developed as an attractive solution to overcome the drawbacks found in most polymer membranes, such permeability-selectivity trade-off and low physicochemical stability. Numerous fillers based on inorganic, organic, hybrid materials with various structures including porous or nonporous, two-dimensional three-dimensional, used. Demanded fur...

premature rupture of membranes (prom) is one of the most common complications of pregnancy that has a major impact on neonatal outcomes. with respect to racial, nutritional and cultural differences between developed and developing countries, this study was conducted to detect the prevalence of neonatal complications following prom and the role of the duration of rupture of membranes in producin...

A variety of clinical manifestations of mercury intoxication may be encountered depending mainly upon the mercurial involved. Inhalation of elemental mercury results in pulmonary, central nervous system (CNS) and kidney damage. The CNS damage produces a spectrum of behavioural and neurological deficits. Ingestion of inorganic mercurials may, because of their corrosive nature, produce devastatin...

Stimulation of Mg(2+)-dependent inorganic pyrophosphatase activity several fold by disruption of mitochondrial membranes does not appreciably alter the catalytic properties of the enzyme. Stimulation is due to increased accessibility of substrate to the enzyme, which is not solublized on activation. The enzyme is attached to the inside of the inner membrane, and under physiological conditions p...

The ways in which certain inorganic elements are used in essential roles within biological systems generally are described. The two roles stressed are (1) electrolytic charge movements and (2) electronic charge movement. The value of helical proteins inside and outside membranes as mechanical coupling devices is analysed.

To understand the generic role of soft, hydrated biopolymers in adjusting interfacial interactions at biological interfaces, we designed a defined model of the cell-extracellular matrix contacts based on planar lipid membranes deposited on polymer supports (polymer-supported membranes). Highly uniform polymer supports made out of regenerated cellulose allow for the control of film thickness wit...

Researchers favor polymeric membranes for water treatment because of their excellent separation selectivity, high membrane performance, unique interconnected structure and inexpensive cost. Electrospinning, phase inversion, track-etching, slip casting, film-stretching are some the methods fabricating membranes. Among them, electrospun nanofiber (ENMs) most actively explored which address foulin...
