Relationship of haptoglobin phenotype and levels with sight-threatening diabetic retinopathy in type 2 diabetes: A Fenofibrate Intervention and Event Lowering in diabetes (FIELD) substudy.

Aims: Haptoglobin (HP) phenotype has been reported to modulate fenofibrate benefit on coronary artery disease in type 2 diabetes. It is unknown whether HP phenotype and levels modulate fenofibrate benefit on sight-threatening diabetic retinopathy (STDR).

Methods: In plasma from 8,047 Australasian adults with type 2 diabetes in the FIELD trial, HP phenotype was determined, and HP levels were measured at baseline and after six-week fenofibrate run-in.

Tunable Multicolor Luminescence in Double Perovskite [(CH)N]KEuTb(NO) Single Crystals.

Tunable multicolor luminescence materials can flexibly meet the needs of smart lighting, enabling efficient light energy use and minimizing waste. Lead-free hybrid double perovskites AMM(NO) hold great potential in luminescence, benefiting from their tunable composition, high light absorption, low synthesis cost, and environmental friendliness. However, achieving tunable multicolor emission within a single matrix of these materials has yet to be realized.

Tumor‑stroma ratio as a clinical prognostic factor in colorectal carcinoma: A meta‑analysis of 7,934 patients.

The tumor-stroma ratio (TSR) has been regarded as an important factor associated with tumor metastasis, based on the 'seed and soil' theory, which may have guiding significance for the selection of chemotherapy regimens. Therefore, a high TSR may be a new risk factor for tumor recurrence in patients with stage II colorectal cancer (CRC). The present study aimed to evaluate the prognostic value of TSR in CRC, especially for the computer-calculated TSR.

Neoadjuvant cabozantinib for locally advanced nonmetastatic clear cell renal cell carcinoma: a phase 2 trial.

Cabozantinib is an oral multikinase inhibitor approved for treatment in metastatic renal cell carcinoma (RCC). We conducted a phase 2, nonrandomized, single-arm clinical trial (NCT04022343) of cabozantinib treatment for 12 weeks in 17 patients with locally advanced, biopsy-proven, nonmetastatic clear cell RCC before surgical resection. The primary end point was the objective response rate (complete and partial responses) at week 12 and secondary end points included safety, tolerability, clinical and surgical outcomes, and quality of life.

The overlooked contribution of aquaculture to phosphorus pollution in estuary water with phosphate oxygen isotope.

Phosphorus is one of the key contributors to the eutrophication of aquatic ecosystems. With the rapid growth of the aquaculture industry, aquaculture effluent has gradually become a significant source of phosphorus pollution. However, this important phosphorous source has often been overlooked in previous studies.

Hole-Mediated Lattice Oxygen Redox Design for Perovskite Oxide Catalysts.

Present design and application of perovskite oxide catalysts assume lattice oxygen redox (LOR) mechanisms that depend on lattice oxygen activity without consideration of the entire redox cycle. Herein, using in situ characterizations and theoretical calculations, we uncover a hole-mediated LOR cycle on p-type Sr-deficient SrFeO (SFO-Srv) perovskites in CO oxidation reaction. Sr vacancies activate surface lattice oxygen of SFO-Srv and promote formation of highly covalent Fe-O sites.

Once-weekly glucagon-like peptide receptor agonist polyethylene glycol loxenatide protects against major adverse cardiovascular events in patients with type 2 diabetes: a multicenter ambispective cohort study (FLYING trial).

This study aimed to determine the effects of polyethylene glycol loxenatide (PEG-Loxe), a glucagon-like peptide-1 receptor agonist, on a three-point major adverse cardiovascular event (3P-MACE) in patients with type 2 diabetes mellitus (T2DM). The study was conducted in six tertiary hospitals in three cities in China. Large language models were used to retrospectively screen and include 12,341 patients with T2DM who had either cardiovascular disease or cardiovascular risk factors.

Age- and sex-specific reference intervals for sex hormones in children in Wuhan: a cross-sectional study of 2,477 healthy children and adolescents.

Background: The standards for diagnosing, monitoring, and treating endocrine diseases in pediatric patients often rely on laboratory assessments of children's growth and differentiation markers, among which sex hormones are pivotal. Nonetheless, due to the rapid development during childhood and adolescence and the substantial physiological differences between children and adults, sex hormone levels undergo significant fluctuations. Unfortunately, few laboratories in China currently provide reliable reference intervals (RIs) for children's sex hormones.

Effect of Feeding Mice Soluble Metals and Heavy Metal Contaminated Soil on Feces Metal Concentrations.

The effect of heavy metal availability and interaction in feed on feces heavy metal excretion in mice has rarely been investigated. In this work, feed containing a polluted soil (total Cd = 6.34, total Pb = 387 mg kg) amended with phosphate, bentonite and lime, or feed spiked with soluble Pb and Cd were fed to mice for 10 days.

Absent in melanoma 2: a potent suppressor of retinal pigment epithelial-mesenchymal transition and experimental proliferative vitreoretinopathy.

Epithelial-to-mesenchymal transition (EMT) is a critical and complex process involved in normal embryonic development, tissue regeneration, and tumor progression. It also contributes to retinal diseases, such as age-related macular degeneration (AMD) and proliferative vitreoretinopathy (PVR). Although absent in melanoma 2 (AIM2) has been linked to inflammatory disorders, autoimmune diseases, and cancers, its role in the EMT of the retinal pigment epithelium (RPE-EMT) and retinal diseases remains unclear.

New motivation for injury prevention in the face of dramatic demographic changes in China.

Our manuscript reviewed the enormous number of deaths caused by different types of injuries in China and around the world and proposed a new motivation for injury prevention to address sharp demographic changes and promote constant economic growth when China faces ageing, fewer children and industrial upgrading.

Real-time monitoring of ONOO⁻ in cerebral ischemia-reperfusion injury mouse models using a hydrazine-based NIR fluorescent probe.

Mutual suppression of MnO and SiO in an innovative anode design for enhanced cycling stability.

We designed a SiO@C/MnO composite material with ultrafine particle size using a simple sol-gel method and calcination process. SiO and MnO components produce a mutual suppression effect during the charge/discharge process to mitigate volume expansion and maintain the long-term stability of composite.

Engineering vanadium vacancies to accelerate ion kinetics for high performance zinc ion battery.

Vanadium dioxide (VO) has attracted significant attention in aqueous zinc ion batteries (AZIBs) owing to their desirable theoretical specific capacity originated from multiple electrons transfer reaction and special crystal structure. However, sluggish electrochemical kinetics leads to inferior electrochemical storage performance. Herein, rich vanadium vacancies were introduced in tunnel VO to boost Zn diffusion, increasing charge storage capacity and lengthen lifespan.

STING modulates HBV-related acute-on-chronic liver failure by mediating autophagy and macrophage polarization.

Background & Aims: HBV-related acute-on-chronic liver failure (HBV-ACLF) is a severe acute liver injury secondary to HBV-related chronic liver disease (with or without cirrhosis) and is characterized by a high short-term mortality rate. Presently, there is a paucity of experimental models that specifically focus on HBV-ACLF based on chronic hepatitis B. Therefore, this study aimed to establish an experimental mouse model of HBV-ACLF using chronic hepatitis B (CHB) as a basis and investigate the impact of STING activation on the disease.

Evi1 governs Kdm6b-mediated histone demethylation to regulate the Laptm4b-driven mTOR pathway in hematopoietic progenitor cells.

Ecotropic viral integration site 1 (EVI1/MECOM) is frequently upregulated in myeloid malignancies. Here, we present an Evi1-transgenic mouse model with inducible expression in hematopoietic stem/progenitor cells (HSPCs). Upon induction of Evi1 expression, mice displayed anemia, thrombocytopenia, lymphopenia, and erythroid and megakaryocyte dysplasia with a significant expansion of committed myeloid progenitor cells, resembling human myelodysplastic syndrome/myeloproliferative neoplasm-like (MDS/MPN-like) disease.
