Light-Controlled Intracellular Synthesis of Poly(luciferin) Polymers Induces Cell Paraptosis.

Accumulation of misfolded proteins challenges cellular proteostasis and is implicated in aging and chronic disorders. Cancer cells, moreover, face an elevated level of basal proteotoxic stress; hence, exacerbating endoplasmic reticulum (ER) stress has been shown to induce programmed cell death while enhancing anticancer immunogenicity. We hypothesize that hydrophobic abiotic macromolecules can trigger a similar stress response.

In vitro antimicrobial activity of six novel β-lactam and β-lactamase inhibitor combinations and cefiderocol against NDM-producing Enterobacterales in China.

Introduction: To date, the global prevalence of New Delhi metallo-β-lactamase (NDM) in carbapenem-resistant Enterobacterales (CRE) has been of concern, which is not inhibited by classical β-lactamase inhibitors (BLIs). In this study, we investigated the newly developed antimicrobial agents or inhibitors against NDM-producing Enterobacterales (NPEs).

Methods: The in vitro activities of cefiderocol, cefepime/taniborbactam, meropenem/taniborbactam, cefepime/zidebactam, meropenem/nacubactam, aztreonam/nacubactam and aztreonam/avibactam were analyzed in 204 NPE strains collected in China.

Methods: We systematically reviewed the prognostic role of clinicopathological and genomic factors in resected IMA patients.

PTER is a N-acetyltaurine hydrolase that regulates feeding and obesity.

Taurine is a conditionally essential micronutrient and one of the most abundant amino acids in humans. In endogenous taurine metabolism, dedicated enzymes are involved in the biosynthesis of taurine from cysteine and in the downstream metabolism of secondary taurine metabolites. One taurine metabolite is N-acetyltaurine.

ImmRNA: a database of RNAs associated with tumor immunity.

The relationship between different ribonucleic acids (RNAs) and tumor immunity has been widely investigated. However, a systematic description of tumor immune-related RNAs in different tumors is still lacking. We collected the relationship of tumor immune-related RNAs from the published literature and presented them in a user-friendly interface, "ImmRNA" (http://www.

C-reactive protein to albumin ratio as a prognostic tool for predicting intravenous immunoglobulin resistance in children with kawasaki disease: a systematic review of cohort studies.

Background: Intravenous immunoglobulin (IVIG) is the primary treatment for Kawasaki disease (KD). However, 10-20% of KD patients show no response to IVIG treatment, making the early prediction of IVIG resistance a key focus of KD research. Our aim is to explore the application of the C-reactive protein to albumin ratio (CAR) for predicting IVIG resistance in children with KD through meta-analysis.

A PTER-dependent pathway of taurine metabolism linked to energy balance.

Taurine is a conditionally essential micronutrient and one of the most abundant amino acids in humans. In endogenous taurine metabolism, dedicated enzymes are involved in biosynthesis of taurine from cysteine as well as the downstream derivatization of taurine into secondary taurine metabolites. One such taurine metabolite is N-acetyltaurine.

Rice husk hydrochar prepared by hydrochloric acid assisted hydrothermal carbonization for levofloxacin removal in bioretention columns.

Hydrochars are promising adsorbents in pollutant removal for water treatment. Herein, hydrochloric acid (HCl) co-hydrothermally treated hydrochars were prepared from rice husk biomass at 180 °C via a one-step hydrothermal method. Adsorption behaviors of levofloxacin (LVX) on hydrochars were evaluated.

Long-term outcomes of esophageal and gastric cancer patients with cardiovascular and metabolic diseases: A two-center propensity score-matched cohort study.

Background And Objectives: An increased risk of cardiovascular and metabolic diseases (CVMDs) among patients with cancer suggests a potential link between CVMD and cancer. The impact of CVMD on the survival time of patients with esophageal and gastric cancer remains unknown. We aimed to determine the incidence of CVMD and its impact on the longterm outcomes in esophageal and gastric cancer patients.

Aryldiazonium Salt-Triggered [2 + 2 + 1] Heteroannulation of Indoles by an Arylhydrazone Radical-Relayed 1,5-Hydrogen Atom Transfer.

An unprecedented three-component [2 + 2 + 1] annulation cascade of indoles with aryldiazonium salts and polyhalomethanes or acetone is presented by dual hydrogen atom transfer (HAT) and C-H functionalization. By employing readily accessible aryldiazonium salts as the radical initiators and electrophiles and polyhalomethanes and acetone as the C1 units, this method unprecedentedly constructs a pyrazole ring on an indole ring skeleton through the formation of two C-N bonds and a C-C bond in a single reaction.

Opportunities and challenges of protein-based targeted protein degradation.

In the 20 years since the first report of a proteolysis targeting chimeric (PROTAC) molecule, targeted protein degradation (TPD) technologies have attempted to revolutionize the fields of chemical biology and biomedicine by providing exciting research opportunities and potential therapeutics. However, they primarily focus on the use of small molecules to recruit the ubiquitin proteasome system to mediate target protein degradation. This then limits protein targets to cytosolic domains with accessible and suitable small molecule binding pockets.

Identification of Novel Stemness-based Subtypes and Construction of a Prognostic Risk Model for Patients with Lung Squamous Cell Carcinoma.

Background: Although cancer stem cells (CSCs) contribute to tumorigenesis, progression, and drug resistance, stemness-based classification and prognostic signatures of lung squamous cell carcinoma (LUSC) remain unclarified. This study attempted to identify stemness-based subtypes and develop a prognostic risk model for LUSC.

Methods: Based on RNA-seq data from The Cancer Genome Atlas (TCGA), Gene-Expression Omnibus (GEO) and Progenitor Cell Biology Consortium (PCBC), mRNA expression-based stemness index (mRNAsi) was calculated by one-class logistic regression (OCLR) algorithm.

Importance of Chain Length in Propagation Reaction on OH Formation during Ozonation of Wastewater Effluent.

During the ozonation of wastewater, hydroxyl radicals (OH) induced by the reactions of ozone (O) with effluent organic matters (EfOMs) play an essential role in degrading ozone-refractory micropollutants. The OH yield provides the absolute OH formation during ozonation. However, the conventional "tert-Butanol (BuOH) assay" cannot accurately determine the OH yield since the propagation reactions are inhibited, and there have been few studies on OH production induced by EfOM fractions during ozonation.

Molecular profiling and prognostic biomarkers in chinese non-small cell lung cancer cohort.

Introduction: Comprehensive information about the genome analysis and its prognostic values of NSCLC patients in Chinese population are still needed.

Pd-Catalyzed Intermolecular Carbonylative Dearomatization of Arylamines with Propargylic Acetates for Synthesis of Bridged Polycyclic Lactams.

A new palladium-catalyzed multicomponent dearomatization of arylamines with CO and propargylic acetates for the synthesis of bridged polycyclic lactams is described. This method allows double annulation at the and positions of the amino group to form four new bonds, three C-C bonds and one C-N bond. DFT calculations and experimental studies indicate that the efficient formation of the allenecarboxanilide intermediate is the key step to achieve the dearomative transformation.

Results: Eleven studies with 2865 patients were included.

A tunable full-color lanthanide noncovalent polymer based on cucurbituril-mediated supramolecular dimerization.

The construction of lanthanide multicolor luminescent materials with tunable photoluminescence properties has been developed as one of the increasingly significant topics and shown inventive applications in miscellaneous fields. However, fabricating such materials based on synergistically assembly-induced emission rather than simple blending of different fluorescent dyes together still remains a challenge. Herein, we report a europium-based noncovalent polymer with tunable full-color emission, which is constructed from the 2,6-pyridinedicarboxylic acid-bearing bromophenylpyridinium salt.
