The role of swelling in hypoxic/ischemic neuronal injury is incompletely understood. We investigated the extent and time course of cell swelling during hypoxia, and recovery of cell volume during reoxygenation, in the CA1 region of rat hippocampal slices in vitro. Cell swelling was measured optically and compared with simultaneous measurements of the extracellular DC potential, extracellular [K...

hydrogel nanocomposites based on alginate polysaccharide were prepared by graft copolymerization of acrylamide and itaconic acid in the presence of carbon nanotube, using methylene bisacrylamide and ammonium persulfate as crosslinker and initiator, respectively. the synthesized samples were characterized by infrared spectroscopy, thermogravimetric analysis and scanning electron microscopy. the ...

in order to determine outcome of pregnancy with lui in patients with unexplained recurrent miscarriage whose husbands have low hypo-osmotic swelling test scores, a prospective clinical intervention was performed at a university referral clinic of recurrent abortion. out of 56 patients whose husbands had abnormal hypo-osmotic swelling tests, 43 patients underwent lui, from which only 14 patients...

We report a new crosslinked polymersome with pH-responsive swelling properties through acidic hydrolysis of hydrophobic contents from the amphiphilic polymer chains. Its unique stability under physiological conditions and large swelling capability under low pH conditions give this polymersome promising potential for anticancer drug delivery.

Brain edema formation occurs after dysfunctional control of extracellular volume partly through impaired astrocytic ion and water transport. Here, we show that such processes might involve synergistic cooperation between the glial water channel aquaporin 4 (AQP4) and the transient receptor potential isoform 4 (TRPV4), a polymodal swelling-sensitive cation channel. In mouse retinas, TRPV4 coloca...

It has been found that ion implantation can induce a swelling (step-height) phenomenon on crystal surface. In this paper, we studied about the control of swelling height of Si crystal by irradiating Ar beam under various parameters (fluence, charge and energy). These irradiation parameters were regulated by an irradiation facility that enables to achieve the multiple ionization. For both charge...

results gelatin films exhibited good tensile strength and elongation at break, water solubility, swelling, and water vapor permeability. incorporation of tam into the gelatin films caused a significant decrease in tensile strength and swelling, and a significant increase in elongation at break, water solubility, water vapor permeability and whiteness of the films. gelatin films exhibited low an...
