Disentangling Driving Force Effects, Polar Effects, /H Imbalance, and Other Influences on H-Atom Transfer Reactions.

Hydrogen atom transfer (HAT) reactions and their kinetic barriers Δ are important in organic and inorganic chemistry. This study examines factors that influence Δ, reporting the kinetics and thermodynamics of HAT from various ruthenium bis(acetylacetonate) pyridine-imidazole complexes to nitroxyl radicals. Across these 36 reactions, the Δ and Δ can be independently varied, with different sets of Ru complexes primarily tuning either their ps or their °s.

With more than half the global population on social media, there is a critical need to understand how to engage it in a way that improves rather than worsens user well-being. Here, we show that positive empathy is a promising tool. Participants who received brief positive empathy instructions before 10 min of browsing their own Instagram feed showed greater affective well-being (Studies 1-4) and life satisfaction (Study 4) at posttest relative to participants who were instructed to browse as usual.

Coral reefs are highly productive ecosystems that provide valuable services to coastal communities worldwide. However, both local and global anthropogenic stressors, threaten the coral-algal symbiosis that enables reef formation. This breakdown of the symbiotic relationship, known as bleaching, is often triggered by cumulative cell damage.

Objectives: To determine the features of rheumatoid pulmonary nodules and the factors associated with nodule progression in patients with rheumatoid arthritis.
Methods: Between January 2010 and September 2018, RA patients with at least one chest computed tomography (CT) were included. Two experienced radiologists examined chest CTs.
Hydrogen Sulfide (HS) Generated in the Colon Induces Neuropathic Pain by Activating Spinal NMDA Receptors in a Rodent Model of Chronic Constriction Injury.

Neuropathic pain (NP) imposes a significant burden on individuals, manifesting as nociceptive anaphylaxis, hypersensitivity, and spontaneous pain. Previous studies have shown that traumatic stress in the nervous system can lead to excessive production of hydrogen sulfide (HS) in the gut. As a toxic gas, it can damage the nervous system through the gut-brain axis.
