Gender, modification

No chemical modification of the enzyme is required. The methods utilize gender conditions as compared to covalent binding and entrapment methods. Entrapment in alginate or K-carragenans is a fairly gende... 

Calculated Clearance. The mathematical relationship between plasma creatinine and GFR can be improved by correcting for the confounding variables that make that relationship nordinear. More than 25 different formulas have been derived that estimate GFR using plasma creatinine corrected for some or all of gender, body size, race, and age. These may produce a better estimate of GFR than serum creatinine alone. Indeed the National Kidney Foundation of the United States has recommended that such estimates should be used in preference to serum creatinine, and that either the Cockcroft and Gault or Modification of Diet in Renal Disease (MDRD) formula should be used in adults. The Schwartz and Counahan-Barratt formulas are recommended for use in children. 

In the analyses of the six IBR items, maternal-hair Hg concentration was significantly associated only with examiner ratings of activity level during the test session and only in males. The score decreased 1 point (on a 9-point scale) for each 10 ppm. Additional analysis of the data of the main SCDS study cohort failed to identify significant effect modification by factors such as caregiver intelligence, H.O.M.E. score, family income, and gender (Davidson et al. 1999). 

Sramek (1981) and Bernstein (1986) further developed empirical equations also with biometrical data such as patient height, actual weight, ideal weight, body surface area, age, and gender. Other transthoracic equations have also appeared (reviewed by Moshkovitz et al., 2004), partly with proprietary modifications, making methods more accurate but perhaps less robust in the case of, for instance, critically ill patients or validity before and after surgery. Bernstein and Osypka (2003) and Bernstein and Lemmens (2005) introduced an index of transthoracic aberrant conduction (e.g., by excess extravascular lung water) in their equations. Suttner et al. (2006) tried it on critically ill patients with acceptable results. 

Current evidence identifies a number of effect modifiers in children social stress and environmental enrichment gender differences race as a factor may operate through higher exposures in U.S. African-American children. Similarly, socioeconomic status affects both race/ethnicity outcomes and relative Pb exposures studies adjusting for exposure differences report effect modification bySES...
