Article Abstract

By use of a macrocyclic phosphinite pincer ligand and bulky substrate substituents, we demonstrate how the mechanical bond can be leveraged to promote the oxidative addition of an interlocked 1,3-diyne to a rhodium(I) center. The resulting rhodium(III) bis(alkynyl) product can be trapped out by reaction with carbon monoxide or intercepted through irreversible reaction with dihydrogen, resulting in selective hydrogenolysis of the C-C σ-bond.

Background: Major depressive disorder (MDD) is associated with neuro-immune - metabolic - oxidative (NIMETOX) pathways.

Aims: To examine the connections among NIMETOX pathways in outpatient MDD (OMDD) with and without metabolic syndrome (MetS); and to determine the prevalence of NIMETOX aberrations in a cohort of OMDD patients.

Methods: We included 67 healthy controls and 66 OMDD patients and we assessed various NIMETOX pathways.

The weak land carbon sink hypothesis.

Sci Adv

September 2025

Department of Earth System Science, University of California, Irvine, CA 92697, USA.

Over the past three decades, assessments of the contemporary global carbon budget consistently report a strong net land carbon sink. Here, we review evidence supporting this paradigm and quantify the differences in global and Northern Hemisphere estimates of the net land sink derived from atmospheric inversion and satellite-derived vegetation biomass time series. Our analysis, combined with additional synthesis, supports a hypothesis that the net land sink is substantially weaker than commonly reported.

Shocked quartz grains are an accepted indicator of crater-forming cosmic impact events, which also typically produce amorphous silica along the fractures. Furthermore, previous research has shown that shocked quartz can form when nuclear detonations, asteroids, and comets produce near-surface or "touch-down" airbursts. When cosmic airbursts detonate with enough energy and at sufficiently low altitude, the resultant relatively small, high-velocity fragments may strike Earth's surface with high enough pressures to generate thermal and mechanical shock that can fracture quartz grains and introduce molten silica into the fractures.

The nitrogen-fixing, chemolithoautotrophic genus is found across numerous diverse environments worldwide and is an important member of many ecosystems. These species serve as model systems for their metabolic properties and have industrial applications in bioremediation and sustainable protein, food and fertilizer production. Despite their abundance and utility, the majority of strains are without a genome sequence, and only eight validly published species are known to date.

Microbial contamination of absorbable collagen membranes used in guided bone regeneration (GBR) may compromise healing outcomes. This study aimed to investigate whether the minimum inhibitory concentration (MIC) of hydrogen peroxide (HO) can improve the antibacterial effect of indocyanine green (ICG)-mediated antimicrobial photodynamic therapy (PDT) on absorbable collagen membranes while reducing the need for high HO concentrations. A laboratory-based model was developed using Streptococcus sanguinis and Staphylococcus aureus.
