BACKGROUND Molecular hydrogen (H2) functions as an extensive protector against oxidative stress, inflammation and allergic reaction in various biological models and clinical tests; however, its essential mechanisms remain unknown. H2 directly reacts with the strong reactive nitrogen species peroxynitrite (ONOO-) as well as hydroxyl radicals (•OH), but not with nitric oxide radical (NO•). We hyp...

BACKGROUND Ara h2 sIgE serum levels improve the diagnostic accuracy for predicting peanut allergy, but the use of Ara h2 purified protein as a skin prick test (SPT), has not been substantially evaluated. The fraction of exhaled nitric oxide (FeNO) shows promise as a novel biomarker of peanut allergy. Reproducibility of these measures has not been determined. The aim was to assess the accuracy a...

The storage capacity of hydrogen on Na-decorated born nitride nanotubes (BNNTs) is investigated by using density functional theory within Quantum Espresso and Gaussian 09. The results obtained predict that a single Na atom tends to occupy above the central region of the hexagonal rings in (5,0) and (3,3) BNNT structures with a binding energy of -2.67 and -4.28 eV/Na-atom respectively. When a si...

H2 pure-rotational emission lines are detected from warm (100–1500 K) molecular gas in 17/55 (31% of) radio galaxies at redshift z < 0.22 observed with the Spitzer IR Spectrograph. The summed H2 0–0 S(0)–S(3) line luminosities are L(H2) = 7 × 1038–2 × 1042 erg s−1, yielding warm H2 masses up to 2 × 1010 M . These radio galaxies, of both FR radio morphological types, help to firmly establish the...

Increased oxidative stress and pro-inflammatory conditions, commonly present in chronic dialysis patients, are thought to be enhanced during hemodialysis (HD) and to be associated with the excess morbidity and mortality seen in these patients. The hydrogen molecule (H2) has a unique biological capacity to act as an antioxidative and anti-inflammatory substance. In light of accumulating evidence...

The human asialoglycoprotein receptor, an endocytic transport receptor of the basolateral surface of hepatocytes, is a hetero-oligomer of two homologous subunits H1 and H2. The cytoplasmic domain of H1 has been shown previously to contain a tyrosine-based signal for endocytosis and basolateral sorting. Here, we have investigated sorting determinants within subunit H2 and their contribution to t...

Steam reforming of ethanol in the membrane reactor using the Pd77Ag23 membrane was evaluated in Ni/CeO2 and Co/CeO2 at atmospheric pressure. At 673 K, the H2 yield in the Pd77Ag23 membrane reactor over Co/CeO2 was found to be higher than that over Ni/CeO2, although the H2 yield over Ni/CeO2 exceeded that over Co/CeO2 at 773 K. This difference was owing to their reaction mechanism. At 773 K, the...
