Several beta-adrenergic blocking agents are on the market in Western Germany. They differ not only in their beta-blocking potency and selectivity but also in their unspecific effects, as intrinsic activity and membrane stabilizing properties. Also the pharmacokinetic behaviour varies widely. From the clinical point of view the selectivity is important for avoiding an aggravation of an underlying obstructive lung disease of effects in the peripheral vascular bed. The intrinsic activity on the one hand might be responsible for some side effects like nightmare or headache; the slowing of resting heart rate on the other hand might be less pronounced. The discrepancies of bio-availability might be overcome by increasing the oral dose.

Assessing self-determined motivation for drinking alcohol via the Comprehensive Relative Autonomy Index for Drinking.
Front Psychol
January 2025
Department of Kinesiology, Pennsylvania State University, State College, PA, United States.
Introduction: Self-Determination Theory (SDT) examines human motivation in multiple domains; however, the only existing measure assessing SDT-informed behavioral regulations for drinking focuses on responsible drinker behaviors, rather than drinking , which is important given the alignment between SDT and harm reduction approaches to alcohol use. The aim of this study was to test the structural validity of the SDT-informed Comprehensive Relative Autonomy Index for Drinking (CRAI-Drinking) among college students.
Methods: Participants included two convenience samples with a total of 630 adult drinkers (M = 21.
Quantifying Asymmetric Coordination to Correlate Oxygen Reduction Activity in Fe-Based Single-Atom Catalysts.

Precisely manipulating asymmetric coordination configurations and examining electronic effects enable to tuning the intrinsic oxygen reduction reaction (ORR) activity of single-atom catalysts (SACs). However, the shortage of a definite relationship between coordination asymmetry and catalytic activity makes the rational design of SACs ambiguous. Here, we propose a concept of "asymmetry degree" to quantify asymmetric coordination configurations and assess the effectiveness of active moieties in Fe-based SACs.

Ammonia synthesis via nitrate electroreduction is more attractive and sustainable than the energy-extensive Haber-Bosch process and intrinsically sluggish nitrogen electroreduction. Herein, we have designed a single-site Cu catalyst on hierarchical nitrogen-doped carbon nanocage support (Cu/hNCNC) for nitrate electroreduction, which achieves an ultrahigh ammonia yield rate (YR) of 99.4 mol h g (2.

Background: Macranthoside B (MB) is a saponin compound extracted from hon-eysuckle that has been reported to exhibit significant medicinal values, particularly anti-tumor activities. This study aimed to evaluate the anticancer efficacy of MB in treating adenocarci-noma of the esophagogastric junction (AEG) and elucidate its underlying mechanisms.
Methods: Three AEG cell lines and normal gastric epithelial cells were used to assess the an-ticancer activity of MB in vitro.
Intrinsic p53 activation restricts gammaherpesvirus driven germinal center B cell expansion during latency establishment.

Gammaherpesviruses are DNA tumor viruses that establish lifelong latent infections in lymphocytes. For viruses such as Epstein-Barr virus and murine gammaherpesvirus 68, this is accomplished through a viral gene-expression program that promotes cellular proliferation and differentiation, especially of germinal center B cells. Intrinsic host mechanisms that control virus-driven cellular expansion are incompletely defined.
