Circular RNA expression in turkey skeletal muscle satellite cells is significantly altered by thermal challenge.

Introduction: Understanding the genetic mechanisms behind muscle growth and development is crucial for improving the efficiency of animal protein production. Recent poultry studies have identified genes related to muscle development and explored how environmental stressors, such as temperature extremes, affect protein production and meat quality. Non-coding RNAs, including circular RNAs (circRNAs), play crucial roles in modulating gene expression and regulating the translation of mRNAs into proteins.

Research Priorities for Childhood Apraxia of Speech: A Long View.

This article introduces the Special Issue: Selected Papers From the 2022 Apraxia Kids Research Symposium. The field of childhood apraxia of speech (CAS) has developed significantly in the past 15 years, with key improvements in understanding of basic biology including genetics, neuroscience, and computational modelling; development of diagnostic tools and methods; diversity of evidence-based interventions with increasingly rigorous experimental designs; and understanding of impacts beyond impairment-level measures. Papers in this special issue not only review and synthesize the some of the substantial progress to date but also present novel findings addressing critical research gaps and adding to the overall body of knowledge.

Research Note: Chicken breast muscle satellite cell function: effect of expression of CNN1 and PHRF1.

The Wooden Breast myopathy results in the necrosis and fibrosis of breast muscle fibers in fast-growing heavy weight meat-type broiler chickens. Myogenic satellite cells are required to repair and regenerate the damaged muscle fibers. Using Genome Wide Association, candidate genes affected with Wooden Breast have been previously reported.

Acoustic Analyses of Tone Productions in Sequencing Contexts Among Cantonese-Speaking Preschool Children With and Without Childhood Apraxia of Speech.

Purpose: Pitch variations (tone productions) have been reported as a measure to differentiate Cantonese-speaking children with and without childhood apraxia of speech (CAS). This study aims to examine fundamental frequency (0) changes within syllables and the effects of syllable structure, lexical status, and syllable positions on 0 in Cantonese-speaking preschool children with and without CAS.

Method: Six children with CAS, six children with non-CAS speech sound disorder plus language disorder (S&LD), 22 children with speech sound disorder only (SSD), and 63 children with typical speech-language development (TD) performed the tone sequencing task (TST).
