Investigating the association between family connectedness and self-control in adolescence in a genetically sensitive design [PDF]

European Child & Adolescent Psychiatry, 2020
AbstractFamily connectedness is key for the development of self-control in early and middle childhood. But is family connectedness still important during the transitional phase of adolescence, when adolescents demand more independence from their parents and rely more on their peers?

Evaluation of connectedness in the registered population of the Sardinian dairy sheep breed

Italian Journal of Animal Science, 2010
Connectedness across flocks of the registered population of the Sardinian dairy sheep breed was evaluated. Used criteria were: number of sires used in the same contemporary group; number of direct links and the average within and between contemporary ...

Spatial modelling improves genetic evaluation in smallholder breeding programs

Genetics Selection Evolution, 2020
Background Breeders and geneticists use statistical models to separate genetic and environmental effects on phenotype. A common way to separate these effects is to model a descriptor of an environment, a contemporary group or herd, and account for ...

Simulation analysis to test the influence of model adequacy and data structure on the estimation of genetic parameters for traits with direct and maternal effects

Genetics Selection Evolution, 2001
Simulations were used to study the influence of model adequacy and data structure on the estimation of genetic parameters for traits governed by direct and maternal effects.

Effects of data structure on the estimation of covariance functions to describe genotype by environment interactions in a reaction norm model

Genetics Selection Evolution, 2004
Covariance functions have been proposed to predict breeding values and genetic (co)variances as a function of phenotypic within herd-year averages (environmental parameters) to include genotype by environment interaction.

Population Structure in the Roundtail Chub (Gila robusta Complex) of the Gila River Basin as Determined by Microsatellites: Evolutionary and Conservation Implications. [PDF]

PLoS ONE, 2015
Ten microsatellite loci were characterized for 34 locations from roundtail chub (Gila robusta complex) to better resolve patterns of genetic variation among local populations in the lower Colorado River basin.

Managing the risk of comparing estimated breeding values across flocks or herds through connectedness: a review and application

Genetics Selection Evolution, 2007
Comparing predicted breeding values (BV) among animals in different management units (e.g. flocks, herds) is challenging if units have different genetic means.

Estimation of Population-Specific Genetic Parameters Important for Long-Term Optimum Contribution Selection—Case Study on a Dairy Istrian Sheep Breed

Animals, 2021
The Istrian sheep breed has been subjected to selection for dairy traits for more than two decades. However, a detailed study of some important population-specific parameters such as effective population size (Ne) and connectedness between flocks has ...

Experience With Performing Rheocarna Therapy via the Single‐Needle Method for Treatment of Chronic Limb‐Threatening Ischemia

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This study investigated the safety and efficacy of single‐needle Rheocarna therapy for chronic limb‐threatening ischemia (CLTI) with wounds. Methods Six patients with CLTI involving ulcers unresponsive to revascularization underwent single‐needle Rheocarna treatment.
