“Data from the slaughter of 24,001 chickens that were part of a selection program for the production of commercial broilers were used to estimate genetic trend for absolute carcass (CW),
breast meat (BRW), and leg (LW) weights, and relative carcass (CY), https://www.selleckchem.com/ALK.html breast meat (BRY), and leg (LY) weights. The components of (co) variance and breeding values of individuals were obtained by the restricted maximum likelihood method applied to animal models. The relationship matrix was composed of 132,442 birds. The models included as random effects, maternal additive genetic and permanent environmental for CW, BRW, LW, CY, and BRY, and only maternal permanent environmental for LY, besides the direct additive genetic and residual effects, and as fixed effects, hatch week, parents’ mating group and sex. The estimates of genetic trend were obtained by average regression of breeding value on generation, and the average genetic trend was estimated by regression coefficients. The genetic trends for CW (+ 6.0336 g/generation), BRW (+ 3.6723 g/generation), LW (+ 1.5846 g/generation), CY (+ 0.1195%/generation), and BRY (+ 0.1388%/generation) were positive, and they were in accordance SB431542 with
the objectives of the selection program for these traits. The genetic trend for LY(-0.0019%/generation) was negative, possibly due to the strong emphasis on selection for BRY and the negative correlations between these two traits.”
“To examine whether childhood cancer survivors’ perceptions of the impact of cancer are related to quality of life (QOL) and psychological distress.
621 survivors (aged 18-39 years) completed a mailed survey assessing distress and QOL. Hierarchical linear
regression models analyzed the independent effects of perceived impacts of cancer on distress and QOL and the extent to which positive and negative perceptions attenuated the effects of covariates on outcomes.
After accounting for perceptions of cancer’s impact on their lives, employment/occupation status, marital/relationship status, and health problems were observed to be significant predictors of QOL and distress. Psychological distress and the mental health component of QOL appeared to be less influenced by sociodemographic PLX3397 nmr status and health problems and more a function of how survivors perceive cancer as impacting their lives.
Results suggest that distress and QOL are partially a function of survivors’ perceptions of how cancer has affected them and continues to affect them in both positive and negative ways. Future research is needed to examine combinations of pharmacological, psychological and/or social interventions that are likely to result in better outcomes in this population.”
