Polycationic ferritin, a multivalent ligand, was used as a visual probe to determine the distribution and density of anionic sites on the surfaces of rat liver mitochondrial membranes. Both the distribution of bound polycationic ferritin and the topography of the outer surface of the inner mitochondrial membrane were studied in depth by utilizing thin sections and critical-point dried, whole mo...

various kinds of chemicals are used in papermaking to enhance paper properties and to improve efficiency of the production process. in the presence of cationic starch as an anionic charge catcher, effects of nano silica/cationic polyacrylamide complex on retention, drainage time, water volume drained by dynamic drainage jar and properties of paper recycled from old corrugated container were inv...

The reversal of the inhibitory action of antiseptics by substances showing a specific affinity for the inhibiting agent has been reported for many compounds, the most striking effect probably being the reversal of the action of mercurials by H2S, glutathione, sodium thioglycolate, etc. Valko and DuBois (1944) have reported that the germicidal action of cationic detergents against both gram-posi...

Human group IIA phospholipase A(2) (hGIIA) is secreted from a number of cells during inflammation and is known to interact strongly with anionic membranes and to exhibit potent Gram-positive bactericidal activity. This protein contains 23 cationic residues, which are scattered over its entire surface, resulting in a high pI of 9.39. To understand the molecular basis for the selective binding of...

Despite intense research in FLP chemistry, nothing is known about monomolecular anionic FLPs and/or complexes thereof. Herein, synthesis and reaction of the first anionic FLP complex is described using [(OC)5W{(Me3Si)2HCP(H)OLi(12-crown-4)}], Cy2BCl and subsequent deprotonation by KHMDS. The obtained anionic FLP complex reacts readily with CO2 in a concerted manner.

The distribution of anionic binding sites has been investigated in the isolated Golgi complex using cationic ferritin. The greatest density of anionic sites occurs on the tubular network and small vesicles, and this binding is accompanied by increased levels of galactosyltransferase activity. The density of anionic sites on the cisternae is less than on the tubules and shows anisotropic distrib...

Current work presents the first investigation on Mode II fracture toughness of room temperature curable acrylic Elium® resin and toughened Elium®IM with 10% weight acrylonitrile butadiene styrene (ABS) particle different thermoplastic fabrics like Ultra-high molecular polyethylene (UHMWPE), polypropylene (UHMWPP), polyester. The testing methodology using doublers, performance under loading unde...

The cell biological mechanism controlling the regeneration of renal tubules in renal failure after application of stem/progenitor cells is subject of actual research. Unsolved issues are the integration of stem/progenitor cells in a diseased organ environment, the differentiation into epithelial tissue and the formation of tubules in a spatial environment. Following this therapeutic strategy ne...
