Recent advancements in tissue engineering have promoted the development of nerve guidance conduits (NGCs) that significantly enhance peripheral nerve injury treatment, improving outcomes and recovery rates. However, utilising tailored biomimetic three-dimensional (3D) topological porous structures combined with multiple bio-effect neurotrophic factors to create environments similar to neural tissues, regulate local immune responses, and develop a supportive microenvironment to promote peripheral nerve regeneration and repair poses significant challenges. Herein, a biomimetic extracellular matrix (ECM) NGC featuring an interconnected 3D porous network and sustained delivery of insulin-like growth factor-1 (IGF-1) is designed using multi-functional gelatine microcapsules (GMs).

Aidi injection (ADI) is utilized in various cancers as a traditional Chinese medicine prescription. This study explores the molecular mechanism by which ADI, when combined with gefitinib, attenuates gefitinib resistance in PC9GR NSCLC cells.

This study uses varying amounts of pyrite as the substrate in RSHCW, leveraging the recirculation of wastewater to alter microenvironments such as dissolved oxygen (DO) and pH, to explore the potential mechanisms of nitrogen (N) and phosphorus (P) removal in pyrite-based RSHCW. The results show that as the proportion of pyrite increases, the removal rate of total phosphorus (TP) in the effluent also increases (25%→58%), significantly enhancing the deposition of iron-bound phosphorus (Fe-P) on the substrate, thereby turning CW into a P reservoir.

This study aimed to estimate the prevalence of hepatitis B virus (HBV) infection in Shandong Province, eastern China (updating our previous study in 2014), and to help guide the efforts of hepatitis B elimination.
Methods: We determined prevalence of HBV infection from the remaining serum samples collected through a population-based survey, which was originally intended for a seroepidemiological survey of anti-SARS-CoV-2 antibodies conducted in 2023.
Inhibitors targeting cyclin-dependent kinases 4 and 6 (CDK4/6) to block cell cycle progression have been effective in treating hormone receptor-positive breast cancer, but triple-negative breast cancer (TNBC) remains largely resistant, limiting their clinical applicability. The study reveals that transcription regulator cyclin-dependent kinase7 (CDK7) is a promising target to circumvent TNBC's inherent resistance to CDK4/6 inhibitors. Combining CDK4/6 and CDK7 inhibitors significantly enhances therapeutic effectiveness, leading to a marked decrease in cholesterol biosynthesis within cells.

However, the evolution of CRLM during drug treatment remains poorly elucidated. Multi-omics and treatment response data from 115 samples of 49 patients with CRLM undergoing bevacizumab (BVZ)-based chemotherapy show little difference in genomic alterations in 92% of cases, while remarkable differences are observed at the transcriptomic level.

Due to the lack of suitable culture systems, the pathogenesis of HuNoVs and the development of vaccines and drugs have progressed slowly. Although researchers have employed various methods to culture HuNoVs in vitro in the last century, problems relating to the irreducibility, low viral titer, and non-infectiousness of the progeny virus should not be ignored.

Methods: Clinical data from 94 neonates with brain injury and 90 neonates without, admitted to Baoji Maternity and Child Healthcare Hospital between September 2022 and February 2024, were retrospectively analyzed. The relationship between aEEG score, NSE level, and Neurobehavioral Neurological Assay (NBNA) score was analyzed by Pearson's correlation analysis.
The transcriptional heterogeneity of tumor microenvironment (TME) cells is a crucial factor driving the diversity of cellular response to drug treatment and resistance. Therefore, characterizing the cells associated with drug treatment and resistance will help us understand therapeutic mechanisms, discover new therapeutic targets and facilitate precision medicine. Here, we describe a database, scDrugAct (http://bio-bigdata.

We hypothesized that specialized Regulatory T (Treg) cells are necessary for bone repair and interact directly with SSCs through organ-specific messages. Both in human patients with bone fracture and mouse model of bone injury, we identified a bone injury-responding Treg subpopulation with bone-repair capacity marked by CCR8.

In this study, inspired by bone composition, biomimetic mesoporous bioactive glass nanoparticle (MBG)/bovine serum albumin (BSA) bone grafts are designed for inflammatory bone defects. Systematically, MBG/BSA bone grafts are evaluated for characterization, bioactivity, anti-inflammatory, antioxidant activity, and osteogenic activity.
