On the other hand, the number of PTC non-tasters at the lowest concentration is higher at 34 students, the number decreases as the concentration of PTC also increases.

This corresponds to previous findings in Generation R Bouthoorn et al. The same was found for Caucasians and non-Caucasians examined separately and for boys and girls examined separately.

All models presented in section 4 were run with additional adjustments for child sex only main effects modelschild BMI at outcome, firstborn status, gestational age at birth, birth weight, maternal age, maternal educational level, marital status, family income, maternal smoking during pregnancy, maternal psychological stress.

Missing covariates were imputed by multiple imputation techniques in SPSS version As adjustments did not significantly change the effects estimates, unadjusted results from unimputed data are presented.

Results of separate linear food fussiness score and logistic fussy eater classification analyses adjusted for Caucasian genotype.

Interaction effects were calculated in models containing also the main effects. Interaction effects of Prop-taster and RS variables with child sex were also tested: All child sex interactions were non-significant and are therefore not shown here.

PROP-taster status was related to a lower risk of being a fussy eater, mainly in boys. However, considering the large number of tests, these findings are likely due to chance.A study of Karkar Island, Papua New Guinea provides further evidence, in a traditional society, for an association between phenylthiocarbamide taster status and goiter.

Correlation between phenylthiocarbamide taster status and quinine sensitivity Introduction Each person has unique preferences for certain tastes and types of food. Differences in smoking-related variables based on phenylthiocarbamide “taster” status. Phenylthiocarbamide (PTC) To determine whether taster status might also protect smokers against nicotine dependence and reinforcement from smoking, we compared tasters with non-tasters in a sample of regular smokers.

Original Article Alternative genetic models for the inheritance of the phenylthiocarbamide taste deficiency. Mar 22,  · The ability to test phenylthiocarbamide (PTC), is a classic phenotype that has long been known to vary in human populations. This phenotype is of genetic, epidemiologic, and evolutionary interest because the ability to taste PTC is correlated with the ability other bitter substances, many of which are toxic (Wooding et al., ).

DNA of the JEG-3 cell line was screened for PTC taster and non-taster status (Figure 5B,C).
