Effectiveness of a smartphone application on dental anxiety in adolescents: A randomized controlled trial.

Background: Dental anxiety is a common issue among adolescents. Despite the use of smartphones being an important part of their daily lives, only a few digital-based interventions for dental anxiety have been tested in randomized controlled trials (RCT).

Aim: The aim of this study was to evaluate a new smartphone application (App) named FALE, which was designed to demonstrate interest from the dentist to adolescent and to reduce dental anxiety.

Free thyroxine but not TSH levels are associated with decline in functional status in a cohort of geriatric outpatients.

Purpose: To assess the associations between TSH and free thyroxine (FT4) levels and decline in functional status in euthyroid older patients at risk of frailty.

Design: Longitudinal prospective study.

Methods: Participants from the geriatric outpatient clinic of a university hospital, who fulfilled the criteria for frailty or were at risk of frailty, were recruited.

Self-reported symptoms of temporomandibular pain and jaw dysfunction in adolescents are associated with exposure to violence.

Background: Temporomandibular disorders (TMDs) are multifactorial, and high levels of stress seem to increase symptoms. The association with exposure to violence has not been explored in adolescent populations.

Objective: To examine the association of self-reported symptoms of temporomandibular pain and jaw dysfunction with child physical abuse, intimate partner violence, forced sexual intercourse, and bullying victimisation.

Determinants of self-perceived oral health in adolescents: A cross-sectional study.

Background: Self-perceived oral health (SPOH) is a summary of multiple determinants related to oral health and has been suggested for use in clinical practice as a health assessment tool.

Aim: To analyse determinants of SPOH among adolescents.

Design: In 2018, we selected 1742 participants from eight high schools in Olinda/PE, Brazil, using a multistage stratified cluster sample.

Differences in the skeletal muscle transcriptome profile associated with extreme values of fatty acids content.

Background: Lipids are a class of molecules that play an important role in cellular structure and metabolism in all cell types. In the last few decades, it has been reported that long-chain fatty acids (FAs) are involved in several biological functions from transcriptional regulation to physiological processes. Several fatty acids have been both positively and negatively implicated in different biological processes in skeletal muscle and other tissues.

Genomic structure and marker-derived gene networks for growth and meat quality traits of Brazilian Nelore beef cattle.

Background: Nelore is the major beef cattle breed in Brazil with more than 130 million heads. Genome-wide association studies (GWAS) are often used to associate markers and genomic regions to growth and meat quality traits that can be used to assist selection programs. An alternative methodology to traditional GWAS that involves the construction of gene network interactions, derived from results of several GWAS is the AWM (Association Weight Matrices)/PCIT (Partial Correlation and Information Theory).

Identification of genomic regions associated with feed efficiency in Nelore cattle.

Background: Feed efficiency is jointly determined by productivity and feed requirements, both of which are economically relevant traits in beef cattle production systems. The objective of this study was to identify genes/QTLs associated with components of feed efficiency in Nelore cattle using Illumina BovineHD BeadChip (770 k SNP) genotypes from 593 Nelore steers. The traits analyzed included: average daily gain (ADG), dry matter intake (DMI), feed-conversion ratio (FCR), feed efficiency (FE), residual feed intake (RFI), maintenance efficiency (ME), efficiency of gain (EG), partial efficiency of growth (PEG) and relative growth rate (RGR).

Genome-wide association study for intramuscular fat deposition and composition in Nellore cattle.

Background: Meat from Bos taurus and Bos indicus breeds are an important source of nutrients for humans and intramuscular fat (IMF) influences its flavor, nutritional value and impacts human health. Human consumption of fat that contains high levels of monounsaturated fatty acids (MUFA) can reduce the concentration of undesirable cholesterol (LDL) in circulating blood. Different feeding practices and genetic variation within and between breeds influences the amount of IMF and fatty acid (FA) composition in meat.
