Structure of Hydrothermally Stable Acid Sites and their Catalytic Role in P-Modified ZSM-5 Zeolite Revealed by Solid-State NMR Spectroscopy.

The ZSM-5 zeolite is the key active component in high-severity fluid catalytic cracking (FCC) catalysts and is routinely activated by phosphorus compounds in industrial production. To date, however, the detailed structure and function of the introduced phosphorus still remain ambiguous, which hampers the rational design of highly efficient catalysts. In this work, using advanced solid-state NMR techniques, we have quantitatively identified a total of seven types of P-containing complexes in P-modified ZSM-5 zeolite and clearly revealed their structure, location, and catalytic role.

Preliminary exploration of the association of CXCR6T lymphocytes in T2D.

Type 2 diabetes (T2D) is a metabolic disease, in which inflammation is a key factor. It has been well established that T cells play important role in antigen-driven immune disorders or immune defense, but were less discussed in inflammatory metabolic diseases. However, accumulating evidences suggest that CD186 (also known as CXCR6)-positive tissue infiltrating T cells might play a key role in inflammatory metabolic diseases.

Excessive Initial Renal Function Decline Following Sodium-Glucose Cotransporter-2 Inhibitor Treatment Predicts Major Adverse Cardiorenal Outcomes.

Objective: To investigate how estimated glomerular filtration rate (eGFR) decline following sodium-glucose cotransporter-2 inhibitors (SGLT2i) initiation predicts long-term cardiorenal outcomes.

Methods: From 2016 to 2020, a longitudinal cohort of 4942 diabetic patients treated with SGLT2i were enrolled and followed until December 2021. Patients were categorized into mild (≤30%), moderate (>30%∼≤40%) and severe (>40%) decline groups by the maximal eGFR change between 2 to 12 weeks after SGLT2i treatment.

Sitravatinib in combination with nivolumab plus ipilimumab in patients with advanced clear cell renal cell carcinoma: a phase 1 trial.

We conducted a phase I trial to determine the optimal dose of triplet therapy with the tyrosine kinase inhibitor sitravatinib plus nivolumab plus ipilimumab in 22 previously untreated patients with advanced clear cell renal cell carcinoma. The primary endpoint was safety. Secondary endpoints were objective response rate (ORR), disease control rate (DCR), duration of response (DOR), progression-free survival (PFS), overall survival (OS), 1-year survival probability, and sitravatinib pharmacokinetics.

Genetic investigations of autosomal recessive inherited ichthyosis impressed by fetal ultrasound: Exome sequencing and haplotype linkage analysis.

Objective: Ichthyosis are complex skin diseases, characterized by hyperkeratosis with various degrees of thickening, desquamation, and erythema. The prenatal diagnosis of ichthyosis is challenged due to the clinical and genetic heterogeneity and the late-onset of fetal features on ultrasound scan. Here, we reported two fetuses with Harlequin ichthyosis (HI), a severe subtype of autosomal recessive congenital ichthyosis (ARCI), who were diagnosed prenatally by images and genetic investigations.

Gut microbes of the cecum versus the colon drive more severe lethality and multi-organ damage.

Intestinal perforations lead to a high risk of sepsis-associated morbidity and multi-organ dysfunctions. A perforation allows intestinal contents (IC) to enter the peritoneal cavity, causing abdominal infections. Right- and left-sided perforations have different prognoses in humans, but the mechanisms associated with different cecum and colon perforations remain unclear.

Transketolase attenuates the chemotherapy sensitivity of glioma cells by modulating R-loop formation.

Glioblastoma (GBM) is a highly lethal malignant brain tumor with poor survival rates, and chemoresistance poses a significant challenge to the treatment of patients with GBM. Here, we show that transketolase (TKT), a metabolic enzyme in the pentose phosphate pathway (PPP), attenuates the chemotherapy sensitivity of glioma cells in a manner independent of catalytic activity. Mechanistically, chemotherapeutic drugs can facilitate the translocation of TKT protein from the cytosol into the nucleus, where TKT physically interacts with XRN2 to regulate the resolution and removal of R-loops.

Non-Additive Gene Expression in Carbon and Nitrogen Metabolism Drives Growth Heterosis in Populus deltoides.

Growth heterosis is crucial for Populus deltoides breeding, a key industrial-timber and ecological-construction tree species in temperate regions. However, the molecular mechanisms underlying carbon (C)-nitrogen (N) metabolism coordination in regulating growth heterosis remain unclear. Herein high-hybrids of P.

Superstable lipid vacuoles endow cartilage with its shape and biomechanics.

Conventionally, the size, shape, and biomechanics of cartilages are determined by their voluminous extracellular matrix. By contrast, we found that multiple murine cartilages consist of lipid-filled cells called lipochondrocytes. Despite resembling adipocytes, lipochondrocytes were molecularly distinct and produced lipids exclusively through de novo lipogenesis.

Relative validity and reproducibility of a short semi-quantitative food frequency questionnaire for Chinese athletes.

A convenient but efficient tool for evaluating dietary intakes in Chinese professional athletes has yet to be established. The aim of this study was to assess the validity of a short semi-quantitative food frequency questionnaire (FFQ) through comparison with 3-day weighed food records (3DWFRs) and corresponding serum biomarkers from a cohort of 102 professional athletes, while also evaluating its reproducibility. The relative validity was assessed using Spearman correlation coefficients, cross-quintiles classification, weighted kappa, and Bland-Altman analysis, while reproducibility was evaluated using the Spearman correlation coefficients and intraclass correlation coefficient (ICC) between two FFQs.

ECM29/proteasome-mediated self-antigen generation by CNS-resident neuroglia promotes regulatory T cell activation.

Proteasomes generate antigenic peptides presented on cell surfaces-a process that, in neuroglia, is highly responsive to external stimuli. However, the function of the self-antigens presented by CNS parenchymal cells remains unclear. Here, we report that the fidelity of neuroglial self-antigens is crucial to suppress encephalitogenic T cell responses by elevating regulatory T (Treg) cell populations.

Lasalocid inhibits melanoma by down-regulating FOXM1 through PI3K/AKT and JNK/P38 MAPK pathways.

Melanoma poses a significant challenge to patients due to its aggressive nature and limited treatment options. Recent studies have suggested that lasalocid, a feed additive ionophore antibiotic, may have potential as an anticancer agent. However, the mechanism of lasalocid in melanoma is unclear.

Accelerating repair of infected bone defects through post-reinforced injectable hydrogel mediated antibacterial/immunoregulatory microenvironment at bone-hydrogel interface.

Functional injectable hydrogel (IH) is promising for infected bone defects (IBDs) repair, but how to endow it with desired antibacterial/immunoregulatory functions as well as avoid mechanical failures during its manipulation has posed as main challenges. Herein, rosmarinic acid (RosA), a natural product with antibacterial/immunoregulatory activities, was utilized to develop a FCR IH through forming phenylboronic acid ester bonds with 4-formylphenyl phenylboronic acid (4-FPBA) grafted chitosan (CS) (FC). After being applied to the IBD site, the FCR IH was then injected with tobramycin (Tob) solution, another alkaline antibacterial drug, to induce in situ crystallization of the FC, endowing the resultant FCRT hydrogel with adaptively enhanced mechanical strength and structural stability.

Spatially Resolved Tumor Ecosystems and Cell States in Gastric Adenocarcinoma Progression and Evolution.

Gastric cancer (GC) is a major cause of global cancer mortality with high levels of heterogeneity. To explore geospatial interactions in tumor ecosystems, we integrated 2,138 spatial transcriptomic regions-of-interest (ROIs) with 152,423 single-cell expression profiles across 226 GC samples from 121 patients. We observed pervasive expression-based intratumor heterogeneity, recapitulating tumor progression through spatially localized and functionally ordered subgroups associated with specific immune microenvironments, checkpoint profiles, and genetic drivers such as SOX9.

FOXC1-mediated serine metabolism reprogramming enhances colorectal cancer growth and 5-FU resistance under serine restriction.

Colorectal cancer (CRC) is the most common gastrointestinal malignancy, and 5-Fluorouracil (5-FU) is the principal chemotherapeutic drug used for its treatment. However, 5-FU resistance remains a significant challenge. Under stress conditions, tumor metabolic reprogramming influences 5-FU resistance.

Inhalable Mucociliary-On-Chip System Revealing Pulmonary Clearance Dynamics in Nanodrug Delivery.

The development of a inhaled nanodrug delivery assessment platform is crucial for advancing treatments for chronic lung diseases. Traditional in vitro models and commercial aerosol systems fail to accurately simulate the complex human respiratory patterns and mucosal barriers. To address this, we have developed the breathing mucociliary-on-a-chip (BMC) platform, which replicates mucociliary clearance and respiratory dynamics in vitro.

VRAC channel inhibition as a novel strategy for the treatment of ischemia-reperfusion injury.

Ischemia-reperfusion injury is a serious clinical pathology involving multiple organs such as the heart and brain. The injury results from oxidative stress, inflammatory response and cell death triggered by restoring tissue blood flow after ischemia, leading to severe cell and tissue damage. In recent years, the volume-regulated anion channel (VRAC) has gained attention as an important membrane protein complex.

Targeting Siglec-15 mediates mitochondrial retrograde regulation of cervical cancer development.

Cervical cancer (CCA) is the predominant cause of fatalities from gynecologic malignancies, with metastasis responsible for 80 % of cancer-related mortalities. This study preliminarily examined the involvement of Sialic Acid Binding Ig Like Lectin 15 (Siglec-15) in the development of CCA and its probable mechanisms. We assessed the capacity of Siglec-15 to modulate CCA progression by establishing knockdown and overexpression Siglec-15 cell lines, supplemented with animal models, using both in vivo and in vitro dual investigations.
