Background: In online mental health communities, the interactions among members can significantly reduce their psychological distress and enhance their mental well-being. The overall quality of support from others varies due to differences in people's capacities to help others. This results in some support seekers' needs being met, while others remain unresolved.

Restenosis remains a long-standing limitation to effectively maintain functional blood flow after percutaneous transluminal angioplasty (PTA). While the use of drug-coated balloons (DCBs) containing antiproliferative drugs has improved patient outcomes, limited tissue transfer and poor therapeutic targeting capabilities contribute to off-target cytotoxicity, precluding adequate endothelial repair. In this work, a DCB system was designed and tested to achieve defined arterial delivery of an antirestenosis therapeutic candidate, cadherin-2 (N-cadherin) mimetic peptides (NCad), shown to selectively inhibit smooth muscle cell migration and limit intimal thickening in early animal PTA models.

Purpose: To investigate the role of S100A8/A9 in the pathogenesis of Sjögren's dry eye disease (SjDED) and explore its potential mechanism of action.
Methods: S100A8/A9 expression was determined by western blot and quantitative real-time polymerase chain reaction (qRT-PCR). Tear secretion, corneal fluorescein staining, and hematoxylin and eosin staining were used to evaluate the effect of paquinimod, a S100A8/A9 inhibitor, on dry eye disease in nonobese diabetic (NOD) mice.

Eccentric planets may spend a significant portion of their orbits at large distances from their host stars, where low temperatures can cause atmospheric CO to condense out onto the surface, similar to the polar ice caps on Mars. The radiative effects on the climates of these planets throughout their orbits would depend on the wavelength-dependent albedo of surface CO ice that may accumulate at or near apoastron and vary according to the spectral energy distribution of the host star. To explore these possible effects, we incorporated a CO ice-albedo parameterization into a one-dimensional energy balance climate model.

Single-atom nanozymes (SAzymes) with excellent biological catalytic activity have emerged as promising candidates for advancing biomedical applications. Herein, we synthesized a RuN-SAzyme by thermal decomposition. In experiments, the RuN-SAzyme demonstrated exceptional catalytic efficiency in mimicking the activity of peroxidase, with a Michaelis-Menten constant () for 3,3',5,5'-tetramethylbenzidine reaching 0.
