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 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.

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.

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.

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.

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.

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.

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.

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.

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.

Accurate and selective techniques for visualizing endogenous peroxynitrite (ONOO) in cerebral ischemia-reperfusion injury (CIRI) models are essential for understanding its complex pathological processes. Here, we introduced a longwave fluorescent probe TJO for detecting ONOO rapidly and sensitively, with a low detection limit of 91 nM. Furthermore, TJO exhibits excellent fluorescence imaging capabilities, enabling detailed visualization of ONOO⁻ in CIRI mice model.

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.

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.

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.

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.

In this study, we introduced a novel fluorescent probe RNP, which demonstrated outstanding sensitivity and specificity for phosgene detection. Upon phosgene exposure, the probe exhibited rapid fluorescence turn-on within a short re-sponse time (6 s). RNP was also effective in both cellular and murine experiments, where fluorescence enhancement was observed in the respiratory tract of mice.

Article Synopsis
  • Pediatric lymphoepithelioma-like carcinoma (pLELC) is a rare cancer with uncertain prognosis, and this study focused on its genomic and clinical features among 41 patients from Sun Yat-sen University Cancer Center.
  • The results showed that patients treated with a combination of anti PD-1 therapy and chemotherapy had high progression-free and overall survival rates, with significant immune-related biomarkers identified in the tumor samples.
  • The study suggests that targeting DNA repair pathways could be a viable treatment strategy for pLELC, and advocates for further clinical trials using immune checkpoint inhibitors in this pediatric population.

Article Synopsis
  • Clinical nurses are essential for enhancing patient care and advancing the healthcare profession, but the connections between their innovative behavior and their perceptions of empowerment in their work remain unclear.
  • This study aimed to explore how innovative behavior relates to structural empowerment and decent work perception among Chinese clinical nurses, while also examining the mediating role of decent work perception.
  • The findings indicated a moderate correlation between innovative behavior, structural empowerment, and decent work perception, suggesting that improvements are needed in these areas to better support clinical nurses in their roles.
