Background: Outer membrane vesicles (OMVs) from Gram-negative bacteria are spherical lipid bilayer nanostructures with diameters of 20 to 250 nm. Porphyromonas gingivalis (P. gingivalis), a keystone periodontal pathogen,...

ABSTRACT Background and Aims Prelabor rupture of membranes is a significant obstetric complication with serious maternal and neonatal consequences. Hypertensive disorders of pregnancy are among the leading contributors t...

A novel full-atom multiscale method, combining different computational approaches and aimed to describe diffusion of multiple ions in anion exchange membranes (AEM), is presented. The method is used to evaluate diffusion...

Water build-up has continued to be one of the leading causes of performance variability and loss of durability in proton exchange membrane fuel cells (PEMFCs), especially at the high current density and transient operati...

ABSTRACT Proton exchange membrane water electrolysis (PEMWE) is a compelling route for sustainable green hydrogen production. Yet Ir‐based oxygen evolution reaction (OER) catalysts suffer from a persistent trade‐off ...

Different continuous operating modes of a nondispersive solvent extraction (NDSX) process with membrane modules of hollow fibre for wastewater treatment and metal recovery are evaluated. Cocurrent and countercurrent flow...

Abstract Milk fats are present as globules emulsified in the aqueous phase of milk and stabilized by a delicate membrane architecture called milk fat globule membrane (MFGM). The unique structure and composition of the M...

Background and aim Membranes for guided bone regeneration should have a mechanical structure and a chemical composition suitable for mimicking biological structures. In this work, we pursue the development of periosteum-...

The outer membrane of gram-negative bacteria is a barrier to chemical and physical stress. Phospholipid transport between the inner and outer membranes has been an area of intense investigation and, in E. coli K-12, it h...

The hydatid disease parasite Echinococcus granulosus has a restricted lipid metabolism, and needs to harvest essential lipids from the host. Antigen B (EgAgB), an abundant lipoprotein of the larval stage (hydatid cyst), ...

The current technology for lithium extraction from brines is recognized both for its techno-economic disadvantages and its environmental impacts. We have synthesized, characterized, and evaluated particles based on lithi...

In this research , microwave ray absorbing coating materials had been prepared which work within ( X - band ) frequency i.e 3 cm wavelength . The coating materials were prepared from a mixture of pigmented materials such...

Leishmaniasis is a zoonotic disease, regarded by WHO as a public health problem that has presented a significant increase in the recent years. Conventional treatment is toxic and leads to serious side effects. Photodynam...

Our understanding of the synthesis and remodeling of mitochondrial phospholipids remains incomplete. Two isoforms of glycerol-3-phosphate acyltransferase (GPAT1 and 2) and two isoforms of acylglycerol-3-phosphate acyltra...

Neurotensin (NT) is a tridecapeptide distributed in central and peripheral nervous systems, which can behave as a neurotransmitter or neuromodulator at central and peripheral levels. Herein we tested the potential effect...

Developing cost-effective and highly durable electrocatalysts to overcome the sluggish kinetics of the oxygen reduction reaction (ORR) is critical for the promotion of proton exchange membrane fuel cells (PEMFCs). In thi...

Abstract Milk fat globule membrane (MFGM) is a lipid carrier in mammals including humans that consists mainly of polar lipids, like phospholipids and glycolipids. In this study, a process to enrich polar lipids in commer...

Nafion exhibits one of the highest proton conductivity at room temperature and it is the standard electrolyte of proton exchange membrane fuel cells (PEMFC). However, the temperature dependence of ionic conductivity of N...
