Objective: To identify the anti-inflammatory effects of artificial musk aqueous extract(AME)on lipopolysaccharide-stimulated cytokines secreted or released by RAW264.7 cells.
Methods: Cytokines including interleukin(IL)-6,IL-10,and tumor necrosis factor Α were determined using cytokine enzyme-linked immunosorbent assay kits.
Result: Compared with model group,the levels of major cytokines such as tumor necrosis factor Α,IL-6,and IL-10 significantly decreased in different AME groups in a dose-dependent manner.
Conclusion: In lipopolysaccharide-stimulated RAW264.7 macrophages,AME can remarkably inhibit the release of inflammatory cytokines and thus exerts its anti-inflammatory effects.

Despite the identification of several dozen genetic loci associated with ischemic stroke (IS), the genetic bases of this disease remain largely unexplored. In this research we present the results of genome-wide association studies (GWAS) based on classical statistical testing and machine learning algorithms (logistic regression, gradient boosting on decision trees, and tabular deep learning model TabNet). To build a consensus on the results obtained by different techniques, the Pareto-Optimal solution was proposed and applied.

In multiple instance learning (MIL), a bag represents a sample that has a set of instances, each of which is described by a vector of explanatory variables, but the entire bag only has one label/response. Though many methods for MIL have been developed to date, few have paid attention to interpretability of models and results. The proposed Bayesian regression model stands on two levels of hierarchy, which transparently show how explanatory variables explain and instances contribute to bag responses.

The term "artificial general intelligence" (AGI) has become ubiquitous in current discourse around AI. OpenAI states that its mission is "to ensure that artificial general intelligence benefits all of humanity." DeepMind's company vision statement notes that "artificial general intelligence…has the potential to drive one of the greatest transformations in history.

Background: Carbapenemase-producing, carbapenem-resistant Pseudomonas aeruginosa (CP-CRPA) are extensively drug-resistant bacteria. We investigated the source of a multistate CP-CRPA outbreak.
Methods: Cases were defined as a US patient's first isolation of P.

In China, the population of wild musk deer, belonging to the family Moschidae, has drastically decreased in recent years owing to human activities and environmental changes. During the 1990s, artificial breeding of Alpine musk deer was conducted in Xinglong Mountain, Gansu Province, China, and their ex situ conservation was explored for over a decade. Ex situ protection is beneficial for expanding the population of animals and maintaining their genetic diversity; however, it can also induce metabolic diseases and parasitic infections and reduce reproductive capacity.
