OBJECTIVE To examine the association between selected unhealthy lifestyle factors, body mass index (BMI), and chronic conditions among individuals 50 years of age or older, by race/ethnicity. DESIGN We analyzed 2001-2004 data from the Behavioral Risk Factor Surveillance System (BRFSS), a state-based system of annual random-digit-dialed telephone surveys. PARTICIPANTS Noninstitutionalized US...

Global warming is increasing permanently, because the concentration of CO2 in the atmosphere is rising continuously. According to National Oceanographic and Atmospheric Administration, the concentration of CO2 in the atmosphere was 407 ppm in June 2016 and 413 ppm in April 2017 as a last record for now. If the effects of other greenhouse gases, such as CH4, N<su...

The specific activities of enzymes catalyzing the ammonium-dependent carbamyl phosphate synthesis (NH(3)-CPS) and the glutamine-dependent carbamyl phosphate synthesis (GLN-CPS) were increased during germination by approximately 5-and 1.7-fold respectively in the presence of 35 mm urea. The increase of NH(3)-CPS and GLN-CPS levels occurred immediately after the onset of germination and prior to ...

Site-directed mutagenesis of the aspartate receptor of Salmonella typhimurium (Tars) at serine 68, a residue located within the aspartate binding pocket and at the subunit interface, identified this residue as an allosteric switch in this receptor. Substitutions at this position can affect both the type and degree of binding cooperativity observed. Negative cooperativity is observed in the wild...

Primary production in the Northern San Francisco Estuary (SFE) has been declining despite heavy loading of anthropogenic nutrients. The inorganic nitrogen (N) loading comes primarily from municipal wastewater treatment plant (WTP) discharge as ammonium (NH(4)). This study investigated the consequences for river and estuarine phytoplankton of the daily discharge of 15 metric tons NH(4)-N into th...

Treatment of [{Ti(η5-C5Me5)(μ-NH)}3(μ3-N)] (1) with one equivalent of [Ni(cod)2] (cod = 1,5-cyclooctadiene) in toluene at 60–80 °C and subsequent addition of diphenylacetylene, trans-stilbene or triphenylphosphane afforded the nickel(0) complexes [LNi{(μ3-NH)3Ti3(η5-C5Me5)3(μ3-N)}] (L = PhCCPh (2), PhCH≡CHPh (3), PPh3 (4)). The nickel(II) complex [I2Ni{(μ3-NH)3Ti3(η5-C5Me5)3(μ3-N)}] (5) was pre...

The effect of exogenous NH(4) (+) on NO(3) (-) uptake and in vivo NO(3) (-) reductase activity (NRA) in roots of Phaseolus vulgaris L. cv Witte Krombek was studied before, during, and after the apparent induction of root NRA and NO(3) (-) uptake. Pretreatment with NH(4)Cl (0.15-50 millimolar) affected neither the time pattern nor the steady state rate of NO(3) (-) uptake.When NH(4) (+) was give...

Ammonia (NH(3)) is a common exogenous gas in the atmosphere, as well as an endogenous chemical produced by amino acid catabolism and other pathways in vivo. Physiological and pathophysiological roles of NH(3) in the nervous system have been studied. Recently, endogenous NH(3) has been suggested to be a gas transmitter. However, so far the role of NH(3) in cardiovascular functions has not been r...

In an attempt to understand the process mediating K(+) transport into roots, we examined the contribution of the NH(4)(+)-sensitive and NH(4)(+)-insensitive components of Rb(+) transport to the uptake of Rb(+) in barley (Hordeum vulgare L.) plants grown in different ionic environments. We found that at low external Rb(+) concentrations, an NH(4)(+)-sensitive component dominates Rb(+) uptake in ...
