Background: Exosomes are released by most cell types, including tumor-associated macrophages (TAMs), transfer diverse macromolecules and participate in intercellular communication in cancer. However, whether M2-polarized TAMs (M2-TAMs)-derived exosomes (M2-exos) transmit the oncogenic protein malate dehydrogenase 1 (MDH1) to reprogram lung adenocarcinoma (LUAD) cancer cells is unknown.
Methods: THP-1-differentiated macrophages were co-cultured with A549 cells to generate TAMs (M0-TAMs and M2-TAMs).

Methods: A retrospective analysis was performed on patients receiving pain management from November 2018 to December 2023 by the MDT. Pain intensity, pain management index (PMI), pain response, and Barthel index of activities of daily living (BADL) were assessed at baseline and/or after 2 weeks of MDT interventions.

Background: Mild cognitive impairment (MCI) has a high risk of progression to Alzheimer's disease. The disease is often accompanied by sleep disorders, and whether sleep disorders have an effect on brain function in patients with MCI is unclear.
Aim: To explore the near-infrared brain function characteristics of MCI with sleep disorders.
Macrocyclic polymer materials exhibit excellent selectivity and adsorption performance in pollutant adsorption due to unique host-guest recognition. Herein, three kinds of calixarene polymers (C4P, C6P and C8P) were synthesized through Sonogashira reaction, and were characterized through H NMR, FT-IR, SEM, and TEM. The water contact angle experiments revealed that three kinds of calixarene polymers were highly hydrophobic, and they all exhibited high enrichment efficiency for weak polar chloro-substituted benzene compounds (chlorobenzene, o-chlorotoluene, p-dichlorobenzene and o-dichlorobenzene) and BTEX (benzene, toluene, ethylbenzene and xylenes).

Recent research has shed light on the role of ferroptosis in various types of cancers, offering a potential avenue for improving cancer therapy. Herein, we identified E3 ubiquitin ligase deltex 2 (DTX2) as a potential therapeutic target candidate implicated in promoting NSCLC cell growth by inhibiting ferroptosis.

In recent years, the combination of HDAC inhibitors and other anticancer chemicals has produced exciting progress in cancer treatment. Herein, we developed a novel prodrug via the ligation of dichloroacetate to selenium-containing potent HDAC inhibitors.

An immobilized enzyme, however, usually compromises its catalytic activity because of inevasible mass transfer issues and the unfavorable conformation changes in a confined environment. Here, we describe a synergetic metal-organic framework pore-engineering strategy to trap lipase (an important hydrolase), which confers lipase-boosted stability and activity simultaneously.

Ef and Fnp infected the human macrophages with different forms (Ef and Fnp monospecies, Ef-Fnp coaggregates, Ef + Fnp cocultures) for exploring the immunoregulatory effects and the relevant molecular mechanisms.

Here, we explored the cardioprotective effects and underlying mechanism of a novel selenium-containing HDAC inhibitor, Se-SAHA, on isoproterenol (ISO)-induced heart failure. We found that pretreatment with Se-SAHA attenuated ISO-induced cardiac hypertrophy and fibrosis in neonatal rat ventricular myocytes (NRVMs).

In this study, we report a convenient scheme for one-step, aqueous-phase synthesis of highly crystalline enzyme@COF biocatalysts. This facile approach relies on an ionic liquid (2 μL of imidazolium ionic liquid)-mediated dynamic polymerization mechanism, which can facilitate the in situ assembly of enzyme@COF under mild conditions.

We aimed to explore the potential mechanism of FZKA in the treatment of NSCLC in this study.
Methods: We obtained the active components and targets of FZKA by TCMSP.
Digital technologies are empowering economic and social development, which attracts scholars' attention to the relationship between digitalization and economic resilience, However, the empirical analysis for different countries and stages of development are inconsistent, and the influencing mechanism need to be further explored. Using panel data for 284 prefecture-level cities in China from 2007 to 2020, this study examines the impact of urban digital development on economic resilience. The findings are as follows: (1) The increased digitalization significantly enhances the urban economic resilience, and this effect was more pronounced in eastern regions and large-scale cities.

Introduction: JAK3 kinase inhibitor has become an effective means to treat tumors and autoimmune diseases.
Methods: In this study, molecular docking and molecular dynamics simulation were used to study the theoretical interaction mechanism between 1-phenylimidazolidine-2-one molecules and JAK3 protein.
Results: The results of molecular docking showed that the six 1-phenylimidazolidine-2-one derivatives obtained by virtual screening were bound to the ATP pocket of JAK3 kinase, which were competitive inhibitors of ATP, and were mainly bound to the pocket through hydrogen bonding and hydrophobic interaction.

With the deep integration of "AI + medicine", AI-assisted technology has been of great help to human beings in the medical field, especially in the area of predicting and diagnosing diseases based on big data, because it is faster and more accurate. However, concerns about data security seriously hinder data sharing among medical institutions. To fully exploit the value of medical data and realize data collaborative sharing, we developed a medical data security sharing scheme based on the C/S communication mode and constructed a federated learning architecture that uses homomorphic encryption technology to protect training parameters.

Based on a sample consist of 581 listed enterprises invested by local VC funds in China during 2009-2021, it's found that, compared to the VC funds invested by local LPs completely (LLP_VC), the VC funds with foreign LP investment (FLP_VC) are more likely to help portfolio enterprises list overseas. If FLP_VC syndicates or act as a major investor, it will have a greater role in promoting the internationalization of enterprises.
