Molecular Engineering of AIE-Active Photosensitizers with High Biosafety for Effect Extracellular Antibacteria.

Developing versatile photosensitizers to actualize selective antibacteria over normal cells presents an appealing yet significantly challenging task. In this study, a novel photosensitizer named DMMA-SCPI is rationally designed and facilely synthesized, which is demonstrated as a type-I photosensitizer featured by aggregation-induced emission tendency. DMMA-SCPI is capable of effectively eliminating both Galanz positive bacteria and Galanz negative bacteria in vitro and in vivo, and showed insignificant injury to normal cells and tissues, probably resulting from its pyridinium halide that has stronger adsorption property on negatively charged bacteria compared to normal cells, as well as its suitable antimicrobial activity.

A prospective, observational study was conducted at a tertiary care ophthalmology center.

Cytoplasmic Aggregates of Splicing Factor Proline-Glutamine Rich Disrupt Nucleocytoplasmic Transport and Induce Persistent Stress Granules.

Splicing factor proline-glutamine rich (SFPQ), a multifunctional RNA-binding protein (RBP), shows cytoplasmic colocalisation with stress granule (SG) markers; however, the causative relationship and mechanism underlying this coalescence of SFPQ aggregates and SGs remain unclear. In this study, we demonstrate that SFPQ lacking its nuclear localisation sequence spontaneously forms cytoplasmic aggregates that abnormally incorporate immature RNA and induce persistent SGs. mRNA profiling showed that SFPQ mislocalisation induced extensive changes in RNA processing, with a subset of alternatively spliced transcripts associated with nucleocytoplasmic transport.

Previous experience of action-effect predictability and delay affect perceived agency and decision-making independently.

The possible cognitive effect of sense of agency (SoA) has attracted increasing attention. Previous findings suggest that SoA has an effect on action control, time perception, and memory. Here we investigated whether SoA can also influence decision-making.

Mechanism of action of Nrf2 and its related natural regulators in rheumatoid arthritis.

Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovitis that can lead to joint deformities. To date, more than 18 million individuals worldwide have been diagnosed with RA, making it one of the most prevalent autoimmune diseases globally and posing a significant threat to public health and safety. Due to the complex pathogenesis of the disease, which involves autoimmunity, genetics, inflammation and oxidative stress in the body's tissues, the current drug therapy generally targets a single molecule, and effective and efficient drugs involving multiple levels and targets are lacking; thus, there is an urgent need for high-quality research and treatment in this field.

Biomarkers Identification of Early Rheumatoid Arthritis via Bioinformatics Approach and Experimental Verification.

Objective: To screen and identify potential biomarker for early rheumatoid arthritis (RA) by bioinformatic analysis and experimental investigation.

Methods: Transcriptome data of RA synovium was downloaded from GEO. Differentially expressed genes (DEGs), gene ontology (GO) functional annotation, and KEGG pathway were analyzed to inspect significative target genes.

Angiotensin-Converting Enzyme-Dependent Intrarenal Angiotensin II Contributes to CTP: Phosphoethanolamine Cytidylyltransferase Downregulation, Mitochondrial Membranous Disruption, and Reactive Oxygen Species Overgeneration in Diabetic Tubulopathy.

The limited therapeutic options for diabetic tubulopathy (DT) in early diabetic kidney disease (DKD) reflect the difficulty of targeting renal tubular compartment. While renin-angiotensin-aldosterone system (RAS) inhibitors are commonly utilized in the management of DKD, how intrarenal RAS contributes to diabetic tubular injury is not fully understood. Mitochondrial disruption and reactive oxygen species (ROS) overgeneration have been involved in diabetic tubular injury.

A new era of cancer phototherapy: mechanisms and applications.

The past decades have witnessed great strides in phototherapy as an experimental option or regulation-approved treatment in numerous cancer indications. Of particular interest is nanoscale photosensitizer-based phototherapy, which has been established as a prominent candidate for advanced tumor treatment by virtue of its high efficacy and safety. Despite considerable research progress on materials, methods and devices in nanoscale photosensitizing agent-based phototherapy, their mechanisms of action are not always clear, which impedes their practical application in cancer treatment.

Effect of preoperative inspiratory muscle training combined with preoperative education on postoperative pulmonary complications in high-risk patients with lung cancer: protocol for a randomised controlled trial.

Introduction: Preoperative inspiratory muscle training (IMT) is recognised as an important component of the preoperative management of lung cancer, although there is limited evidence for the delivery of a home-based IMT programme combined with preoperative education. We developed a programme combining short-term home-based IMT and preoperative physiotherapy education ('the programme'). This study aims to evaluate the effectiveness of this programme in reducing postoperative pulmonary complications (PPCs) after lung cancer resection compared with standard care.

A Pyrrole Modified 3,4-Propylenedioxythiophene Conjugated Polymer as Hole Transport Layer for Efficient and Stable Perovskite Solar Cells.

Despite the outstanding electric properties and cost-effectiveness of poly(3,4-ethylenedioxythiophene) (PEDOT) and its derivatives, their performance as hole transport layer (HTL) materials in conventional perovskite solar cells (PSCs) has lagged behind that of widely used spirobifluorene-based molecules or poly(triaryl amine). This gap is mainly from their poor solubility and energy alignment mismatch. In this work, the design and synthesis of a pyrrole-modified HTL (PPr) based on 3,4-propylenedioxythiophene (ProDOT) are presented for efficient and stable PSCs.

Three-dimensional structural alignment based discovery and molecular basis of AtoB, catalyzing linear tetracyclic formation.

Enzymes from the nuclear transport factor 2-like (NTF2-like) superfamily represent a rare group of biocatalysts with diverse catalytic functions facilitating intriguing skeleton formations. However, most proteins of this family remain enigmatic and await further elucidation. In this study, a combination of protein structural alignment with clustering analysis uncovers a new aldolase, AtoB, belonging to the NTF2-like superfamily.
