It is highly desirable to have a universal detector that can detect all types of compounds and give a uniform response regardless of the physiochemical properties of the compounds. With such a universal detector, all components in a sample can be accurately quantified without the need for individual standards. This is especially needed for the characterization of unknowns and for non-targeted analysis, or for samples that have no isolated standards available for each component. Over the years, much effort has been put into seeking a universal detection technology. In this review, we discuss the commonly used detectors for analytical characterization, including UV, RI, ELSD, CAD, CLND, FID, VUV, MS, NMR, and hyphenated detection, with the focuses on the "universal" features of these detectors regarding the types of molecules they can detect and the uniformity of responses.

This short review bridges two biological fields: ribosomes and nucleosomes-two nucleoprotein assemblies that, along with many viruses, share proteins featuring long filamentous segments at their N- or C-termini. A central hypothesis is that these extensions and tails perform analogous functions in both systems. The evolution of these structures appears closely tied to the emergence of regulatory networks and signaling pathways, facilitating increasingly complex roles for ribosomes and nucleosome alike.

The purpose of this study was to examine the association between behavioral emotion regulation strategies and symptoms of depression, anxiety, and stress among Turkish university students. Participants consisted of 633 students continuing their university education in two different universities in Türkiye. Participants completed a data collection tool comprising a Sociodemographic Information Form, the Behavioral Emotion Regulation Questionnaire, and the Depression Anxiety Stress Scales-21.

Hydrogen (H2), the simplest and most ubiquitous molecule in the universe, has garnered significant scientific interest over the past two decades because of its potential as an effective antioxidant and anti-inflammatory agent. Traditionally considered inert, H2 is now being re-evaluated for its unique bioactive properties. H2 selectively neutralizes reactive oxygen and nitrogen species, mitigating oxidative stress without disrupting essential cellular functions.

Background: The aim of this study is to explore young rural women's perceived barriers in accessing healthcare services with a focus on the interrelation between three marginalization criteria: age (youth), gender (female), and place of residence (rural areas) in Australia, Canada, and Sweden.
Methods: Using a qualitative interpretive approach, we conducted semi-structured in-depth interviews with 31 young women aged 18 to 24 in selected rural communities. Data collection took place from May 2019 to January 2021, and the qualitative data were analyzed using NVivo software.
