We aimed to elucidate the influence of analgesic patterns on mortality among patients with AP hospitalized in the ICU.
Methods: We included 784 patients (198 receiving opioid monotherapy and 586 receiving opioid polytherapy) from the Medical Information Mart for Intensive Care database.
Enzyme-powered micro/nanomotors (EMNMs) represent cutting-edge research taking advantage of enzymes as biocatalysts to provide a driving force for micro/nanomotors. Up to now, EMNMs have been designed to be powered by catalase, urease, lipase, collagenase, compound enzymes, . They not only have good biocompatibility and biosafety but also possess the unique ability to utilize physiologically relevant fuel to achieve autonomous propulsion through catalytic reactions.

Five different surfaces were designed by varying the wettability of the central pillars while keeping the lateral pillars hydrophilic. The nucleation behavior of argon bubbles was observed to differ significantly across these surfaces due to the combined effects of nanostructuring and mixed wettability.

Objective: To explore the antitumor effect of Inonotus obliquus extract on 4T1 tumor-bearing mice in vivo and its possible mechanism.
Methods: 4T1 tumor-bearing mice model was established. After successful modeling, tumor-bearing mice were randomly divided into model control group, cyclophosphamide(CTX) positive group, and high, medium and low dose groups of Inonotus obliquus extract, with 10 mice in each group, which were administered continuously for 21 days.
The transgenic maize DBN9936 × DBN9501, which confers resistance to insects and tolerance to herbicides, was developed via conventional cross breeding of transgenic maize DBN9936 and DBN9501. In our present study, a 90-day feeding toxicity study was conducted on Sprague Dawley rats to evaluate the safety of the maize. A total of 140 rats were randomly assigned to seven groups (n = 10/sex/group): one control group, three genetically modified (GM) groups with 17.

The limited therapeutic options available for PDAC significantly contribute to its high mortality rate, highlighting the urgent need for novel biomarkers capable of effectively identifying early clinical manifestations and facilitating precise diagnosis. The pivotal role of cellular exosomes in both the pathogenesis and therapeutic interventions for PDAC has been underscored.

Soybean agglutinin (SBA) is an anti-nutritional factor in soybean, possesses toxic effects by binding to intestinal epithelial cells, and finally interferes the digestion and absorption of nutrients in humans and animals. Annexin A2 (ANXA2) is one of the SBA-specific binding proteins in intestinal epithelial cells and participates in multiple cellular biological processes. However, whether SBA affects apoptosis through ANXA2 and its apoptosis-related pathway remains unclear.
