Biomass-derived carboxymethyl cellulose lithium (CMCLi) was synthesized from poplar wood (PW) and corn stover (CS) as sustainable binders for lithium-ion batteries. The raw materials were pretreated with green deep eutectic solvents (DESs) to remove lignin and hemicellulose, followed by bleaching to purify the cellulose. The purified cellulose was subsequently subjected to alkaline swelling, alkalization, and etherification to produce CMC-Li binders.

Background: Infants are vulnerable to acute respiratory infections (ARIs), which result in pediatric morbidity and even fatalities. A surge of ARIs among infants and young children was reported in China in 2023, garnering global attention. We aimed to investigate the frequency and types of respiratory pathogens associated with the risk of acute respiratory illnesses in infants and young children during this period.

The licensed adjuvanted recombinant glycoprotein E (gE) subunit vaccine (HZ/su) is highly effective against herpes zoster (HZ). This randomised, active-controlled, non-inferiority trial (ChiCTR2300079076) compared the immunogenicity and safety of a novel gE-Fc fusion protein vaccine candidate (LZ901) with HZ/su in 300 healthy adults aged ≥50 years without prior HZ vaccination in Wuxi, China. Participants received either two doses of LZ901 (30-day interval; n = 151) or HZ/su (60-day interval; n = 149).

Ischemic stroke (IS) is a prevalent and serious neurological disorder, and is one of the major contributors to mortality and disability worldwide. The activation of autophagy and the inflammatory response following cerebral ischemia are crucial in the progression of IS. Protein phosphatase 1 regulatory subunit 15A (PPP1R15A), as a stress-responsive protein, has been proven to be closely associated with autophagy.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline and behavioral changes. Emerging evidence suggests that the gut microbiota influences central nervous system function. Probiotic interventions may offer a promising therapeutic approach by modulating the gut microbiota composition and potentially improving cognitive outcomes in AD patients.

Background & Aims: Intrahepatic cholangiocarcinoma (iCCA) is a highly lethal liver malignancy with poor response rates to chemotherapy. Although translational reprogramming is a recognised hallmark of treatment resistance, its role in iCCA remains unclear. This study aimed to investigate codon-biased translation in iCCA chemoresistance and explore potential therapeutic strategies.

High expression of nucleotide synthetic enzyme thymidylate synthase (TYMS) is responsible for the resistance to fluorouracil (FU) treatment and worse survival in colorectal cancer (CRC). Herein, we revealed that pleckstrin-2 (PLEK2) cooperated with YTHDF2 to enhance TYMS mRNA stability in CRC via an mA dependent manner. Silencing of PLEK2 led to the degradation of TYMS mRNA that suppressed DNA replication, which activated p53/p21 signaling and consequent inhibition of CRC cell proliferation via the cellular senescence.

The efficiencies with which activated B lymphocytes proliferate and develop into antibody (Ab)- secreting plasma cells are critical determinants of adaptive humoral immunity and central to sustaining certain autoimmune diseases. Increasing evidence indicates that specific pathways in intermediary metabolism, or their substrate supply, influence lymphocyte differentiation and function. We now show that although stringent restriction of glutamine supply decreases proliferation and differentiation of B cells into plasma cells, glutaminolysis - a major means of metabolism of this amino acid - was only conditionally crucial in B cells and the Ab responses derived from them.

Resistance to targeted therapies is a significant clinical problem, but eliminating resistant cancer cells has proven difficult. One potential reason for this difficulty is heterogeneity in the resistant population: even genetically homogeneous cancer cell populations can give rise to many resistant subtypes, each potentially with specific second-line drug vulnerabilities. Using high-throughput drug screening of genetically-identical resistant clones with varying transcriptomes and morphologies, we show that each clone had a distinct drug sensitivity profile.

Introduction: Vaccines capable of effectively inducing mucosal immunity, particularly specific IgA antibodies, represent an ideal strategy for preventing infections and the transmission of pathogens such as SARS-CoV-2 and influenza viruses that rapidly replicate in the upper respiratory tract and cause clinical symptoms. However, a lack of standardized nasal antibody detection and sampling methods has hindered cross-study comparability and vaccine development.

Methods: This study uses SARS-CoV-2 as a model pathogen to standardize nasal antibody detection methods and sampling methods.

Plant-derived polyphenols such as syringic acid (SA) are promising modulators of lipid metabolism, yet their clinical utility is limited by poor aqueous solubility. Here, we report a four-step click chemistry strategy to conjugate hydrophilic sugar moieties to SA, yielding a series of sugar-SA triazole derivatives with markedly enhanced solubility and stability. Among these, the glucose conjugate (GS) exhibited the most potent pancreatic lipase (PL) inhibition, surpassing orlistat, and significantly improved cholesterol and bile salt binding.

Introduction: Pathogenic variants in canonical transforming growth factor β (TGFβ) signaling genes predispose patients to thoracic aortic aneurysm and dissection (TAAD), predominantly in aortic root. Although TAAD pathogenesis associated with TGFβ receptor defects is well characterized, distinct and redundant mechanisms of TGFβ isoforms in TAAD incidence and severity remain elusive.

Objective: Here we examined the biological role of TGFB2 in smooth muscle cell (SMC) differentiation and investigated how TGFB2 defects can lead to regional TAAD manifestations.

For patients with human epidermal growth factor receptor 2 (HER2)-low advanced breast cancer who had failed to meet with anthracycline or taxane, the application of HER2-targeted antibody-drug conjugates as second-line therapy could improve patients' outcomes, but it is unclear whether carboplatin-based first-line therapy will benefit these patients. This retrospective study was designed to explore whether carboplatin based first-line treatment could improve outcomes in HER2-low advanced breast cancer, and to analyze potential factors affecting efficacy and prognosis. 103 patients with HER2-negative metastatic breast cancer were treated with carboplatin based first-line therapy.
