The objective of the study was to establish a pink threshold and simulate the pink defect in cooked chicken breast meat with treatment combinations that would induce significant changes in the color of raw and cooked meat. The subjective pink threshold used in judging pink discoloration was established at a* = 3.8. Samples of three color groups (normal, lighter than normal, and darker than norm...

1. The excretion of urea and of chlorides in the normal individual is carried out according to definite laws, capable of numerical expression. 2. The rate of excretion of urea and of sodium chloride is determined by the concentration in the blood, the rate of water output, and indirectly by the weight of the individual. 3. The threshold of sodium chloride excretion is practically constant at ab...

AIM This was to validate a taste test on healthy school children. A cross-sectional study was designed to perform a standardised clinical evaluation of the gustatory sensitivity. MATERIALS AND METHODS Forty (18 males and 22 females) children were selected. Inclusion criteria were age between 5 and 12 years, absence of systemic disease and no antibiotic treatment in the last six months. The...

In order to test the range of pH values over which the titratable carried model for inorganic anion exchange is valid, chloride self-exchange across human red blood cells was examined between pH 4.75 and 5.7 at 0 decrees c. It was found that chloride self-exchange flux had a minimum near pH 5 and increased again with further increase in hydrogen ion activity. The Arrhenius activation energy for...

Glycerinated rabbit psoas fibers 5-19 days old were immersed in contracting solutions with and without varying concentrations of different sodium salts. Raising the pH of the solution in small steps identified a threshold pH above which the fibers rapidly developed maximum tension. In solutions with added chloride or acetate (O-O.15 M), threshold pH and maximum tension changed only slightly. In...

In a recent issue of CHEST (January 2013), Durmowicz et al 1 highlight the fi nding that despite improvement in both cystic fi brosis (CF) transmembrane conductance regulator (CFTR) and pulmonary function in clinical trials of ivacaftor (recently approved by the US Food and Drug Administration for individuals with CF and the G551D mutation), there does not appear to be a direct correlation betw...

in this research genetic and phenotypic parameters were estimated using linear and threshold models, for reproductive traits, data from 6 large industrial dairy herd of east azerbaijan province collected by agriculture jihad organization during 10 years (2001-2010). best linear unbiased predictions of traits breeding values were estimated using restricted maximum likelihood method by wombat sof...
