SINCE we reported the presence of an isotope of oxygen with mass 18 in the earth's atmosphere (NATURE,, 318; 1929) we have found further confirmation. Mr. Harold D. Babcock has sent us thirty-four lines which were withheld from publication by Dieke and Babcock (,, 670; 1927) because ...
The ability of the circulatory, respiratory, and muscular systems to supply oxygen during sustained physical activity. Exercise A subtype of physical activity that is planned, repetitive, and structured, and it has a specific intention of improving or maintaining fitness. ...

TBW,,., was calculated as N,/l.Ol, where 1.01 is a correction for rapidly exchangeable nonaqueous oxygen (23). In early life the hydration of the FFM compartment rapidly changes with age. To convert TBW into FFM, we used data on changes in FFM hydration in infants by gender published ...

A star expands to become a red giant when it has fused all the hydrogen in its core into helium. If the star is in a binary system, its envelope can overflow onto its companion or be ejected into space, leaving a hot core and potentially forming a subdwa
Panx1 channels are permeable to ATP and open in response to various stimuli including mechanical stress, Panx1 ligands, low oxygen concentration, increased K+and intracellular calcium levels, and apoptosis7. In particular, activation of caspase-3 in apoptotic cells results in cleavage of the Panx1...
