We prepared total RNA from the Gram-positive soil bacterium Bacillus subtilis by different RNA extraction procedures to compare their suitability for Northern blot detection of tiny RNAs (~14-mers) or RNAs of intermediate size (100-200 nt) in terms of signal quality, intensity, and reproducibility. Our analysis included two hot phenol methods and two TRIzol extraction procedures. We found that signal intensity/detection sensitivity makes the key difference. Total RNAs prepared by the hot phenol method comprise the length spectrum from tRNAs to large ribosomal RNAs. Larger RNAs are less abundant in TRIzol preparations which instead enrich for RNAs of tRNA size and smaller. Thus, hot phenol methods are the choice for the detection of intermediate-sized and longer RNAs, whereas TRIzol extraction procedures are more suited for the detection of tiny RNAs.

Objective: This study investigated the locations of amino acid modifications within two major human hair keratins (Type I K31 and Type II K85) with probable implications for protein and hair structural component integrity. The particular focus was on cysteine modifications that disrupt intra-protein and inter-protein disulphide bonds.
Methods: Human hair was exposed to accelerated, sequential heat or UV treatments, simulating effects resulting from the use of heated styling tools and environmental exposure over a time frame approximating one year.

Ionic liquids (ILs) are a class of organic salts with melting points below 100°C. Owing to their unique chemical and physical properties, they are used as solvents and catalysts in various chemical transformations, progressively replacing common volatile organic solvents (VOCs) in green synthetic applications. However, their intrinsic ionic nature can restrict the use of mass spectrometric techniques to monitor the time progress of a reaction occurring in an IL medium, thus preventing one from following the formation of the reaction products or intercepting the reaction intermediates.

Introduction: We compared and measured alignment between the Health Level Seven (HL7) Fast Healthcare Interoperability Resources (FHIR) standard used by electronic health records (EHRs), the Clinical Data Interchange Standards Consortium (CDISC) standards used by industry, and the Uniform Data Set (UDS) used by the Alzheimer's Disease Research Centers (ADRCs).
Methods: The ADRC UDS, consisting of 5959 data elements across eleven packets, was mapped to FHIR and CDISC standards by two independent mappers, with discrepancies adjudicated by experts.
Results: Forty-five percent of the 5959 UDS data elements mapped to the FHIR standard, indicating possible electronic obtainment from EHRs.

Background And Aims: Several observational studies have reported inconsistent associations between dyslipidaemia, stains use and atopic dermatitis (AD). Nevertheless, the available data on the effects of -C-lowering as well as TG-lowering drugs remain inconclusive and limited. The aim of this study was to evaluate the causal association of lipid traits and long-term use of lipid-lowering drugs on AD risk.

Background: Nutrition underpins athletic performance, enhancing training, reducing injury risk, and accelerating recovery. In the event of an injury, performance dietitians (PDs) and nutritionists' (PNs) play a vital role by tailoring nutritional strategies to support tissue repair, optimize athlete's recoveries, and return to play.
Objectives: This study explored nutritional strategies recommended and employed by Irish PDs and PNs to assess, manage, and support athletes during the initial stages of sports-related injuries.
