The physicochemical interaction of pediocin PA-1 with target membranes was characterized using lipid vesicles made from the total lipids extracted from Listeria monocytogenes. Pediocin PA-1 caused the time- and concentration-dependent release of entrapped carboxyfluorescein (CF) from the vesicles. The pediocin-induced CF efflux rates were higher under acidic conditions than under neutral and al...

The growing integration of distributed energy resources (DERs) in distribution grids raises various reliability issues due to DER's uncertain and complex behaviors. With large-scale DER penetration grids, traditional outage detection methods, which rely on customers report smart meters' “last gasp” signals, will have poor performance, because renewable generators storage the mesh structure urba...

Phosphatidic acid (PA) is a lipid second messenger that is formed transiently in plants in response to different stress conditions, and plays a role in recruiting protein targets, ultimately enabling an adequate response. Intriguingly, this increase in PA concentration in plants is generally followed by an increase in the phospholipid diacylglycerolpyrophosphate (DGPP), via turnover of PA. Alth...

Paio do Alentejo (PA) is one of the most popular dry-fermented sausages in Portugal. The aim present work was to evaluate effect a high concentration starter cultures with an extended fermentation step on safety and quality PA. Physicochemical parameters, microbiological biogenic amines, colour, texture profile, sensory attributes were assessed. Five starters selected based our previous works. ...

Popped rice is a common, chip and nutritious breakfast item widely consumed in India. We analyzed functional, physicochemical and nutritional properties of raw rice (RR) and popped rice (PR) of some Indian rice cultivars (Kalabhat, Banskathi, JP-73, Kabirajsal, Dehradun Gandheswari). RR of Kabirajisal showed better physical grain quality among all whereas Banskathi and Dehradun gandheswari was ...

Purpose: to determine dependencies and develop a methodology for calculating the geometric dimensions constructing outline of local moisture contours formed in soil space during drip irrigation. Materials methods. The factual basis development was data full-scale (field) measurements drip-moistened their office processing. studies were carried out on experimental sites with different cover, rep...

Vitamin A-transporting protein in chicken plasma was purified by column chromatography on DEAE-Sephadex and Sephadex G-100; the protein formed a complex of retinol-binding protein (RBP) with prealbumin (PA). The molecular weight of the 1:1 molar complex was estimated to be 76,000 by gel filtration, and the sedimentation coefficient (S20,W) was found to be 5.2 S. RBP and PA were dissociated from...

Despite the considerable advances in our understanding of biological processes, the physicochemical relationship between living and nonliving systems remains uncertain and a continuing source of controversy. In this review, we describe a kinetic model based on the concept of dynamic kinetic stability that attempts to incorporate living systems within a conventional physicochemical framework. It...

Thirty-six wild-caught woodchucks (Marmota monax) were charac terized according to sex, weight, trapping locality, liver pathology, and serum or hepatic markers of woodchuck hepatitis virus. Liver subcellular fractions were assayed for microsomal cytochromes P-450, aryl hydro carbon hydroxylase, glutathione, cytosolic enzymes involved in its metab olism (glutathione S-transferase, glutathione p...
