OH-Detected Aromatic Microsolvation of an Organic NO Radical: Halogenation Controls the Solvation Side.
J Phys Chem A
January 2025
Institute of Physical Chemistry, University of Göttingen, Tammannstrasse 6, 37077 Göttingen, Germany.
The persistent organic radical 2,2,6,6-tetramethylpiperidinyloxyl (TEMPO) protects its NO radical center by four methyl groups. Two of them are arranged tightly (t) on one side of the six-membered puckered heterocycle, and the other two more openly (o) on the other side. It is shown by OH stretching infrared spectroscopy in heated supersonic jet expansions that the hydrogen bond and aromatic ring of a first solvating benzyl alcohol have almost no preference for either side.

Background And Aims: Alcohol use disorder (AUD) and hazardous alcohol use are common but underdiagnosed in primary health care (PHC). This study aimed to explore general practitioners' (GPs') experiences and perceptions of using B-Phosphatidylethanol (PEth), a specific quantitative biomarker for alcohol use, in their clinical work with patient consultations and treatment follow-up in Swedish PHC.
Design, Participants, And Setting: Individual interviews were conducted with GPs and resident GPs (n 20) in Swedish PHC and analysed using qualitative content analysis.
Genetic associations between orexin genes and phenotypes related to behavioral regulation in humans, including substance use.

Department of Psychiatry, Rutgers Robert Wood Johnson Medical School, Piscataway, NJ, 08854, USA.
The hypothalamic neuropeptide system of orexin (hypocretin) neurons provides projections throughout the neuraxis and has been linked to sleep regulation, feeding and motivation for salient rewards including drugs of abuse. However, relatively little has been done to examine genes associated with orexin signaling and specific behavioral phenotypes in humans. Here, we tested for association of twenty-seven genes involved in orexin signaling with behavioral phenotypes in humans.

Disulfiram (DSF), which has been traditionally used to treat alcoholism, has been shown to inhibit tumor growth, indicating its potential as an anticancer agent. However, its development and application are hindered by its poor water solubility, instability in physiological environments, and low bioavailability. In this study, phenylboronic acid-chitosan (PBA-CS) grafts were synthesized using the carbodiimide method.

This integrative review systematized the factors that influence access to mental health services for the Homeless Population (HP) in harmful use of alcohol and other drugs in the Psychosocial Care Network (RAPS) in Brazil by categorizing the factors into access "barriers" and "facilitators". We selected 13 corresponding articles and subsequently assessed their methodological quality. We identified 19 access barriers and 22 access facilitators, observing a convergence and complementarity of the factors identified, with no disagreements between authors.
