The signal intensity and mass to charge ratio (m/z) of the precursor or product ions can be visualized in the mass spectrum (MS1) or the tandem mass spectrum (MS/MS), respectively. In a typical spectrum the m/z is plotted on the x-axis while the intensity of precursors or fragments ...
kg/m2estimated for Americans. CONCLUSIONS: The prevalence of obesity in Japanese populations should be estimated using ethnic specific values of BMI, rather than those drawn from Caucasians who tend to have higher BMI in each age group. The prevalence of overweight is increased as age increased in...
When two celestial bodies of comparable mass interact gravitationally, bothorbitabout a fixed point (thecentre of massof the two bodies). This point lies between the bodies on the line joining them at a position such that the products of the distance to each body with the mass of each body...
Volume 3 J.Eaton-Evans, inEncyclopedia of Human Nutrition (Fourth Edition), 2013 Body Mass Index (BMI) BMI relates weight (kg) with height (m) by a simple calculation to indicate body composition (BMI=weight/height2). It is the most commonly used screening measurement for both obesity and...
the ratio of males vs. females was unbalanced in patient group, which may lead to the statistical basis. Third, the age of the patients ranged from 25–65 years, and the effect of the age heterogeneity on cognitive performance is obvious. Fourth, all patients were of chronic types and on...

The monoisotopic mass is typically used in proteomics experiments to describe the mass of a (poly)peptide if its isotopic peaks are resolved in the mass spectrum. A mass spectrum plots the intensity of an ion vs its mass-to-charge ratio. Fig. 1 shows the isotopic peaks in an electrospray ...
Body height has been negatively associated with BMI, suggesting shortness is related to having a higher BMI13. Waist-to-height ratio (WHtR) has been proposed as a more sensitive adiposity index for central obesity as well as superior predictor of cardiovascular risk than BMI14. Furthermore, ...
