Development of Triphenylamine Derived Photosensitizers for Efficient Hydrogen Evolution from Water.

A series of new (donor)₂-donor-π-acceptor (D2-D-π-A) and (acceptor)₂-donor-π-acceptor (A2-D-π-A) organic photosensitizers based on the framework of (Z)-2-cyano-3-(5-(4-(diphenylamino)phenyl)thiophen-2-yl)acrylic acid have been synthesized and characterized. By incorporating groups with different electron-donating or withdrawing abilities, such as dibenzothiophene (DBT), dibenzofuran (DBF), and triazine (TA), into the triphenylamine segment, their photophysical properties have been regulated.  Theoretical calculations were used to explore how various donor-acceptor combinations influence their hydrogen production performance.

Selective embolization can effectively alleviate bleeding symptoms in patients with anorectal hemangioma.

In this manuscript, I comment on the article by Pospisilova published in the recent issue of the journal, in which selective embolization was used to treat anorectal hemangioma, a rare disease causing lower gastrointestinal bleeding. Anorectal hemangioma can easily be mistaken; for example, the patient in this case was previously misdiagnosed with ulcerative colitis. Choosing the appropriate tests and understanding the typical manifestations of anorectal hemangioma under colonoscopy, computerized tomography, magnetic resonance imaging and other tests are beneficial for diagnosis.

Cellular senescence induced by down-regulation of correlates with exon skipping of mitochondrial-related gene .

As the most prevalent type of alternative splicing in animal cells, exon skipping plays an important role in expanding the diversity of transcriptome and proteome, thereby participating in the regulation of diverse physiological and pathological processes such as development, aging, and cancer. Cellular senescence serving as an anti-cancer mechanism could also contribute to individual aging. Although the dynamic changes of exon skipping during cellular senescence were revealed, its biological consequence and upstream regulator remain poorly understood.

Mesenchymal Stem Cells Carrying Viral Fusogenic Protein p14 to Treat Solid Tumors by Inducing Cell-Cell Fusion and Immune Activation.

Chimeric antigen receptor (CAR)-based immune cell therapies attack neighboring cancer cells after receptor recognition but are unable to directly affect distant tumor cells. This limitation may contribute to their inefficiency in treating solid tumors, given the restricted intratumoral infiltration and immunosuppressive tumor microenvironment. Therefore, cell-cell fusion as a cell-killing mechanism might develop a novel cytotherapy aimed at improving the efficacy against solid tumors.

We combined amplicon sequencing with culturable approaches to investigate the effects of these microorganisms on pear tree growth, rhizosphere nutrients and microbial mechanisms.

Role of nasal microbiota in regulating host anti-influenza immunity in dogs.

Background: Numerous studies have confirmed a close relationship between the pathogenicity of influenza and respiratory microbiota, but the mechanistic basis for this is poorly defined. Also, the majority of these studies have been conducted on murine models, and it remains unclear how far these findings can be extrapolated from murine models to other animals. Considering that influenza A virus is increasingly recognized as an important canine respiratory pathogen, this study investigated the cross-talk between nasal and lung tissues mediated by microbes and its association with influenza susceptibility in a beagle dog model.

The interplay between retinoic acid binding proteins and retinoic acid degrading enzymes in modulating retinoic acid concentrations.

The active metabolite of vitamin A, all-trans-retinoic acid (atRA), is critical for maintenance of many cellular processes. Although the enzymes that can synthesize and clear atRA in mammals have been identified, their tissue and cell-type specific roles are still not fully established. Based on the plasma protein binding, tissue distribution and lipophilicity of atRA, atRA partitions extensively to lipid membranes and other neutral lipids in cells.

Synthesis and Characterization of Lipid-Polyzwitterion Diblock Copolymers for Optimizing Micelle Formation to Enhance Anticancer Drug Delivery in 2D and 3D Cell Cultures.

Amphiphilic polymers with distinct polarity differences, known as sharp polarity contrast polymers (SPCPs), have gained much attention for their ability to form micelles with low critical micelle concentrations (CMCs) and potential in anticancer drug delivery. This study addresses the limited research on structure-property relationships of SPCPs by developing various SPCPs and exploring their physicochemical properties and biological applications. Specifically, the superhydrophobic aliphatic palmitoyl (Pal) was coupled to the superhydrophilic zwitterionic poly(2-methacryloyloxyethyl phosphorylcholine) (pMPC) to form Pal-pMPC diblock copolymers.

Electrical activation of periodate by nano-zero-valent cobalt/nitrogen-doped carbon for sulfisoxazole degradation: Insights into rapid electron transfer mechanisms.

Periodate (PI) activation via three-dimensional electrochemical (E) is a promising approach for degrading sulfisoxazole (SIZ), while the scarcity of active sites significantly limits the efficient electron-transfer rate. Herein, we synthesized multiple strongly active zero-valent cobalt (Co) nanoparticles encapsulated in nitrogen-doped carbon (NC) shells through Co-potassium chloride (KCl) doping pyrolysis of Zeolitic Imidazolate Framework-8 (ZIF-8) to induce the rapid electron transfer pathways (ETP). Specifically, molten KCl doping provides confined structures for Co with a diameter of 12.
