In this study, a scanning ion-selective electrode technique (SIET) was applied to measure H(+), Na(+), and NH(4)(+) gradients and apparent fluxes at specific cells on the skin of medaka larvae. Na(+) uptake and NH(3)/NH(4)(+) excretion were detected at most mitochondrion-rich cells (MRCs). H(+) probing at MRCs revealed two group of MRCs, i.e., acid-secreting and base-secreting MRCs. Treatment w...

Although colonic lumen NH(4)(+) levels are high, 15-44 mM normal range in humans, relatively few studies have addressed the transport mechanisms for NH(4)(+). More extensive studies have elucidated the transport of NH(4)(+) in the kidney collecting duct, which involves a number of transporter processes also present in the distal colon. Similar to NH(4)(+) secretion in the renal collecting duct,...

Magnesium amidoborane monoammoniate (Mg(NH(2)BH(3))(2) x NH(3)) which crystallizes in a monoclinic structure (space group P2(1)/a) has been synthesized by reacting MgNH with NH(3)BH(3). Dihydrogen bonds are established between coordinated NH(3) and BH(3) of [NH(2)BH(3)](-) in the structure, promoting stoichiometric conversion of NH(3) to H(2).

A new approach to capture and store CO(2) by mineral carbonation using recyclable ammonium salts was studied. This process integrates CO(2) capture with mineral carbonation by employing NH(3), NH(4)HSO(4), and NH(4)HCO(3) in the capture, mineral dissolution, and carbonation steps, respectively. NH(4)HSO(4) and NH(3) can then be regenerated by thermal decomposition of (NH(4))(2)SO(4). The use of...

Results: Of 442,167 BRFSS respondents who met our study criteria, 81.6% were nonHispanic (NH) White, 8.4% were NH Black, 1.6% were NH Asian, 1.0% were NH American Indian, and 7.4% were Hispanic. Within each racial/ethnic group, weight status as measured by BMI was strongly associated with all five health conditions examined and particularly with diabetes, hypertension, and doctor-diagnosed arth...

This work examines a pH control method using ammonium (NH(4)(+)) as a sustainable proton shuttle in a CEM-equipped BES. Current generation was sustained by adding NH(3) or ammonium hydroxide (NH(4)OH) to the anolyte, controlling its pH at 7. Ammonium ion migration maintained the catholyte pH at approximately 9.25. Such NH(4)(+)/NH(3) migration accounted for 90±10% of the ionic flux in the BES. ...
