Secondary Organic Aerosol from Biomass Burning Phenolic Compounds and Nitrate Radicals can be Highly Viscous over a Wide Relative Humidity Range.

Biomass burning events, including wildfires, can emit large amounts of phenolic compounds such as guaiacol. These phenolic compounds can undergo oxidation by nitrate radicals (NO) to form secondary organic aerosol (SOA). Viscosity and hygroscopicity are key properties that affect SOA's role in atmospheric chemistry, air quality, climate and public health.

VO-Based Spacecraft Smart Radiator with High Emissivity Tunability and Protective Layer.

In the extreme space environment, spacecraft endure dramatic temperature variations that can impair their functionality. A VO-based smart radiator device (SRD) offers an effective solution by adaptively adjusting its radiative properties. However, current research on VO-based thermochromic films mainly focuses on optimizing the emissivity tunability (Δ) of single-cycle sandwich structures.

Preparation of Thermochromic Vanadium Dioxide Films Assisted by Machine Learning.

In recent years, smart windows have attracted widespread attention due to their ability to respond to external stimuli such as light, heat, and electricity, thereby intelligently adjusting the ultraviolet, visible, and near-infrared light in solar radiation. VO(M) undergoes a reversible phase transition from an insulating phase (monoclinic, M) to a metallic phase (rutile, R) at a critical temperature of 68 °C, resulting in a significant difference in near-infrared transmittance, which is particularly suitable for use in energy-saving smart windows. However, due to the multiple valence states of vanadium ions and the multiphase characteristics of VO, there are still challenges in preparing pure-phase VO(M).

Coronary Sinus Metabolite 12,13-diHOME Is a Novel Biomarker for Left Atrial Remodeling in Patients With Atrial Fibrillation.

Background: 12,13-dihydroxy-9Z-octadecenoic acid (12,13-diHOME) has shown potential in protecting against heart disease, but its relationship with atrial fibrillation (AF) remains unknown.

Methods: Coronary sinus (CS) and femoral vein blood samplings were synchronously collected from AF and non-AF subjects (paroxysmal supraventricular tachycardia or idiopathic premature ventricular complexes) who underwent catheter ablation. First, untargeted metabolomic profiling was performed in a discovery cohort (including 12 AF and 12 non-AF subjects) to identify the most promising CS or femoral vein metabolite.

HLA-B*58:01:40 differs from HLA-B*58:01:01 by a single nucleotide change in exon 3, 507 C- > T (codon 145.3 CGC- > CGT).

Indole-3-carbinol (I3C) reduces apoptosis and improves neurological function after cerebral ischemia-reperfusion injury by modulating microglia inflammation.

Indole-3-carbinol(I3C) is a tumor chemopreventive substance that can be extracted from cruciferous vegetables. Indole-3-carbinol (I3C) has been shown to have antioxidant and anti-inflammatory effects. In this study, we investigated the cerebral protective effects of I3C in an in vivo rats model of middle cerebral artery occlusion (MCAO).

Type 1 diabetes, its complications, and non-ischemic cardiomyopathy: a mendelian randomization study of European ancestry.

Background: Type 1 diabetes (T1D) is a significant risk factor for a range of cardiovascular diseases. Nonetheless, the causal relationship between T1D and non-ischemic cardiomyopathy (NICM) remains to be elucidated. Furthermore, the mechanisms responsible for the progression from T1D to NICM have not been definitively characterized.

Indium-catalyzed inter- and intramolecular dithianyl-alkyne metathesis reactions.

Herein, we reported an efficient indium catalyzed dithianyl-alkyne metathesis (DAM) reaction. This strategy allows for the formation of a new C-C double bond and valuable C-S bonds during the metathesis event, and was successfully applied to the synthesis of diverse vinyl dithianyl substituted organic molecules.

BarH-Like Homeobox 2 Suppresses Cell Proliferation, Invasion, and Angiogenesis in Hepatocellular Carcinoma by Activating N-Acetylgalactosaminyltransferase 4.

BarH-like homeobox 2 (BARX2) has been identified to play a key role in the development of multiple cancers. Meanwhile, BARX2 may be an independent prognostic biomarker for patients suffering from hepatocellular carcinoma (HCC). Nevertheless, the regulatory role of BARX2 in HCC is still unclear and needs to be unveiled.

Human umbilical cord derived mesenchymal stem cells overexpressing HO-1 attenuate neural injury and enhance functional recovery by inhibiting inflammation in stroke mice.

Aims: The current evidence demonstrates that mesenchymal stem cells (MSCs) hold therapeutic potential for ischemic stroke. However, it remains unclear how changes in the secretion of MSC cytokines following the overexpression of heme oxygenase-1 (HO-1) impact excessive inflammatory activation in a mouse ischemic stroke model. This study investigated this aspect and provided further insights.

Loss of the accessory chromosome converts a pathogenic tree-root fungus into a mutualistic endophyte.
