Under mild visible light conditions, formates facilitate C-O cleavage the EDA complex and SCS strategy, yielding α-carbonyl alkyl radicals. These radicals then react with olefins under air conditions, leading to the synthesis of diaryl 1,4-dicarbonyl compounds. Mechanistic studies reveal that α-formyloxy ketone is generated by the reaction between α-brominated acetophenone and formates, followed by the formation of the EDA complex.

H-ATPases provide a transmembrane proton gradient and are thought to play a crucial role in plant growth and abiotic stress responses. However, their expression under abiotic stress and function on deep rooting is poorly understood in rice.

Hypoxia-activable prodrugs offer a promising strategy to target tumors in low-oxygen conditions, but their efficacy is often hindered by intrinsic properties and extrinsic cues. In this study, we developed a dual-prodrug nanoassembly system (CPPA) composed of a hypoxia-triggerable camptothecin (CPT)-based dimeric prodrug (CP) and a lipid-conjugated STAT3 antisense oligonucleotide (ASO) prodrug (PA), aiming to enhance tumor-targeted chemotherapy and overcome the immune evasion within the tumor microenvironment.

Therefore, the efficient capture of iodine (I) has attracted considerable attention in recent years. The aluminum cluster-based metal framework materials show great advantage in iodine adsorption due to the designable pore sizes, excellent physicochemical stability, and cheap raw materials.

It is shown that, by increasing the rate of Au deposition, weak cetyltrimethylammonium bromide (CTAB) can be made to behave like a strong ligand, so that it induces Active Surface Growth and gives Au nanowires. The ligand strength also depends on the packing interactions in the ligand layer, in the order of CTAB, CTAB, and CTAB.

Corticosteroids are the standard first-line treatment for primary immune thrombocytopenia (ITP), with a high initial response but unsatisfactory sustained response (SR). Additionally, corticosteroids usually lead to hyperglycaemia especially in patients with pre-existing type 2 diabetes mellitus (T2DM). Besides reducing the blood glucose levels, metformin was found to have immunomodulatory effects.

Overexpression of epidermal growth factor receptor (EGFR) and thioredoxin reductase (TrxR) are commonly associated with an adverse prognosis in hepatocellular carcinoma (HCC). This makes them key targets for the treatment of HCC. Studies have shown that the clinical efficacy of the EGFR tyrosine kinase inhibitor gefitinib alone in treating HCC is limited.

However, due to the absence of engine noise, previously overlooked noise sources are accentuated and detrimentally affect interior noise quality. Road noise is a predominant PEV noise source and significantly contributes to middle- and low-frequency interior noise levels.

Various symmetry-breaking mechanisms such as chiral templates, strain-restriction and asymmetric ligand-binding have been developed to induce the helical growth at nanoscale. In this work, with neither chiral ligands nor templates, gold (Au) nanohelices were synthesized via a facile wet-chemical method, through an asymmetric Active Surface Growth facilitated by colloidal silica nanoparticles (NPs).

Background: Hemoporfin-mediated photodynamic therapy (Hemoporfin-PDT) is considered a safe and effective treatment for port-wine stains (PWS). This study aims to investigate the influence of prior pulse dye laser (PDL) treatments history on the effectiveness of Hemoporfin-PDT in young children aged 1-3 years with PWS.
Methods: Data was gathered for individuals with PWS aged 1-3 years who received two or more Hemoporfin-PDT treatments.
This work proposes a novel plasma-assisted 2D/2D g-CN/TiC system for treatment of organics-heavy metals composite wastewater. Unlike traditional materials in plasma system, 2D/2D g-CN/TiC not only improved the mass transfer efficiency of plasma by gathering both reactive species and pollutants onto the surface, but also induced photocatalytic reactions. Besides, the higher specific surface area and faster carrier separation rate can enhance the oxidation and reduction activity, and then promoted organic matter degradation and heavy metal reduction.
