Nitrogen recovery from swine manure was investigated using gas-permeable membranes. The process involved a continuous recirculation of an acidic solution through a gas-permeable membrane submerged in manure. Ammonia from manure was concentrated in the acidic solution increasing its pH, while pH decreased in manure. In the first set of experiments, nitrogen recovery efficiency was evaluated with...

The paper diachronically examines the white hanbok as material and symbolic site of interaction between hegemonising hegemonised in Korea. It traces changing status from end 19th century to present—from being part unconscious culture, synecdoche colonised nation, symbol resistance, membrane a ‘homogeneous nation’, democracy. analyses paradoxical skin—at once inclusive exclusive—of Korean ethnon...

PURPOSE To determine whether age-related changes in Bruch's membrane affect its permeability to macromolecules. Such changes have been postulated to underlie some pathologic manifestations of age-related macular degeneration. METHODS Bruch's membrane preparations were isolated from the macular region of donated human eyes of differing age and mounted in a modified Ussing chamber. Permeability...

Background: This study was carried out to assess the effects of MnTBAP, a cell permeable antioxidant, on motility, membrane integrity, capacitation status and in vitro fertilization ability of frozen-thawed ram semen. Materials and Methods: Fresh semen ejaculates were collected with artificial vagina from five rams, mixed and divided into five equal fractions, and diluted (1:20 v/v) with commer...

Mammalian type II taste cells release the afferent neurotransmitter adenosine triphosphate (ATP) through ATP-permeable ion channels, most likely to be connexin (Cx) and/or pannexin hemichannels. Here, we show that ion channels responsible for voltage-gated (VG) outward currents in type II cells are ATP permeable and demonstrate a strong correlation between the magnitude of the VG current and th...

To standardise regenerative medicine using cultured cells, the use of serum-free, chemically defined media will be necessary. We have reported that IL-1α inhibits the growth of epithelial cells in culture and that recombinant IL-1 receptor antagonist (IL-1RA) significantly promotes epithelial cell growth in no feeder layer condition. In this study, we examined inhibitors of calpain, a cysteine ...

This paper presents the development of water-permeable dialysis membranes that are suitable for an implantable microdialysis system that does not use dialysis fluid. We developed a microdialysis system integrating microfluidic channels and nanoporous filtering membranes made of polyethersulfone (PES), aiming at a fully implantable system that drastically improves the quality of life of patients...

Graphitic carbon nitride (g-C3N4) with photo-attached platinum (Pt@g-C3N4) is known to generate hydrogen under illumination in aqueous environments the presence of carbohydrate hole quenchers. Here, Pt@g-C3N4 embedded into a polymer intrinsic microporosity (PIM-1) host material molecularly rigid structure maintain active unblocked catalyst surfaces and control transport to/from photocatalyst. A...
