The nano-aggregation of carotenoids in microbial membranes increases membrane stability upon butanol exposure by reducing the fluidization effect and permeability butanol.

Recent studies have demonstrated that actin filaments are not crucial for the short-term stability of tubular membrane protrusions originating from the cell surface. It has also been demonstrated that prominin nanodomains and curvature inducing I-BAR proteins could account for the stability of the membrane protrusion. Here we constructed an axisymmetric model of a membrane protrusion that exclu...

A dog with persistent elliptocytosis was studied. The dog had membrane protein band 4.1 deficiency, microcytosis, shortened erythrocyte lifespan, increased osmotic sensitivity, and a mild glutathione deficiency. Erythrocyte deformability and membrane stability were adversely effected. The dog's parents had decreased band 4.1, decreased stability, and some elliptocytosis. This disorder in dogs c...

Several mammalian enzymes are anchored to the outer surface of plasma membrane by a covalently attached glycosyl-phosphatidylinisitol (GPI) structure. These include acetylcholinesterase, alkalinee phosphatase and 5´-nucleotidase. Recently, it has been reported that these membrane enzymes can be solubilized into the serum by GPI-dependent PLD, under various medical disturbances such as cancer an...

Ceramic membranes are considered as alternatives for their polymeric counterparts due to highmechanical strength and thermal resistance; thus long lifetime. Usually, asymmetric ceramicmembranes are synthesized including several layers with different pore size distributionswith the top-layer playing the main separation role. Titania has several properties such asphotocatalytic activity and chemi...

Although proton-exchange membrane fuel cells (PEMFC) are considered as a safe and clean energy technology, aging phenomena of the membrane-electrode assembly (MEA), more particularly membrane, still restrict PEMFC lifetime. In this paper, ex-situ accelerated chemical degradation – via Fenton's reagents exposure reinforced Nafion™ XL is performed in order to investigate impact on structure prope...

Hereditary spherocytosis and elliptocytosis are the two most common inherited red cell membrane disorders resulting from mutations in genes encoding various red cell membrane and skeletal proteins. Red cell membrane, a composite structure composed of lipid bilayer linked to spectrin-based membrane skeleton is responsible for the unique features of flexibility and mechanical stability of the cel...

in this research, the effects of thidiazuron pulse treatment and salicylic acid were examined to improve vase life and maintain the quality of alstroemeria ҅modena҆ cut flowers. the experiment was done in a factorial experiment based on rcd with 16 treatments, 3 replications and 48 plots. the flowers were placed in different concentrations of thidiazuron (0, 10, 20, and 50 μm) and salicylic acid ...

in order to evaluate the effects of foliar application of methanol on some physiological characteristics of chickpea under drought stress, an experiment was conducted as a factorial based on completely randomized design with three replications in 2011 at the recearch center of plant for sciences in ferdowsi university of mashhad. the first factor was different levels of methanol including, 0 (c...
