Boosting REsources And caregiver empowerment for Tracheostomy care at HomE (BREATHE) Study: study protocol for a stratified randomization trial.

Background: Annually, about 4000 US children undergo a tracheostomy procedure to provide a functional, safe airway. In the hospital, qualified staff monitor and address problems, but post-discharge this responsibility shifts entirely to caregivers. The stress and constant demands of caregiving for a child with a tracheostomy with or without ventilator negatively affect caregivers.

Disruption of tRNA biogenesis enhances proteostatic resilience, improves later-life health, and promotes longevity.

tRNAs are evolutionarily ancient molecular decoders essential for protein translation. In eukaryotes, tRNAs and other short, noncoding RNAs are transcribed by RNA polymerase (Pol) III, an enzyme that promotes ageing in yeast, worms, and flies. Here, we show that a partial reduction in Pol III activity specifically disrupts tRNA levels.

Understanding exogenous factors and biological mechanisms for cognitive frailty: A multidisciplinary scoping review.

Cognitive frailty (CF) is the conjunction of cognitive impairment without dementia and physical frailty. While predictors of each element are well-researched, mechanisms of their co-occurrence have not been integrated, particularly in terms of relationships between social, psychological, and biological factors. This interdisciplinary scoping review set out to categorise a heterogenous multidisciplinary literature to identify potential pathways and mechanisms of CF, and research gaps.

Anther Culture Protocols for Barley and Wheat.

Doubled haploid (DH) techniques remain valuable tools for wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) genetic improvement, and DH populations are used extensively in breeding and research endeavors.
