High pulsed electric fields (PEF) trigger the phenomenon of a transient increase in permeability plasma membranes biological cells, which is known as electroporation [...]

The kinetics of synthesis and degradation of the protein constituents of nuclear membranes, endoplasmic reticulum membranes (rough-surfaced microsomes), G o 1 g i apparatus membranes and plasma membranes were determined following a single administration of L-[guanido-14C] arginine by intraperitoneal injection. Membrane protein was determined as the fraction which resists sonication and sequenti...

Arrhenius plots of fluoride- and guanine-nucleotide-stimulated adenylate cyclase activity were linear in adipocyte plasma membranes from lean and obese (ob/ob) mice. Arrhenius plots of isoprenaline-stimulated adenylate cyclase activity in hepatic plasma membranes biphasic in both groups. The results were biphasic in membranes from lean mice but linear in membranes from obese mice. In contrast, ...

  Objective: Different techniques have been suggested for the repair of bone defects at the injured sites. Use of biomembranes, or application of plasma rich in growth factor (PRGF) at the site of proliferation of osteoblasts are among the suggested techniques. The current study aimed to compare the biocompatibility of human periodontal ligament fibroblasts (hPLF) cultured on Hypro-Sorb F, Peri...

The degradation rates of N-acetylneuraminic acid (NANA) were investigated in plasma membranes and in the total protein of rat liver and Morris hepatoma 7777. The plasma membranes of Morris hepatoma 7777 could not be isolated by known methods useful for isolation of rat liver plasma membranes. Therefore, a modified method was developed. The specific activity of 5'-nucleotidase as a plasma membra...

The plasma membrane surrounding living cells "plays a role in intracellular metabolism, but what distinguishes this structure from other organelles is that the plasma membrane also mediaces interactions between the cell and its external environment. The simplest of these interactions maintain a desirable intracellular milieu by bringing in needed substances and getting rid of waste products. Th...

Hyaline membrane disease of the newborn has been a subject of ever-growing interest to paediatricians and pathologists as it is the major cause of death in newborn babies, particularly premature ones. Much more is known of the clinical picture and physiological changes in hyaline membrane disease, or respiratory distress syndrome of the newborn (Avery, 1962; Curtis, 1957; James, 1959; Miller, 1...

Despite the importance of cholesterol in the formation and function of caveolar microdomains in plasma membranes, almost nothing is known regarding the structural properties, cholesterol dynamics or intracellular factors affecting caveolar cholesterol dynamics. A non-detergent method was employed to isolate caveolae/raft domains from purified plasma membranes of murine fibroblasts. A series of ...
