Biomimetic ECM nerve guidance conduit with dynamic 3D interconnected porous network and sustained IGF-1 delivery for enhanced peripheral nerve regeneration and immune modulation.

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).

Brain radiotherapy combined with camrelizumab and platinum-doublet chemotherapy for previously untreated advanced non-small-cell lung cancer with brain metastases (C-Brain): a multicentre, single-arm, phase 2 trial.

Background: Brain metastases are a common complication in patients with non-small-cell lung cancer (NSCLC) lacking actionable driver mutations, with limited treatment options and poor prognosis. We aimed to investigate the efficacy and safety of brain radiotherapy combined with camrelizumab and platinum-doublet chemotherapy in patients with newly diagnosed advanced NSCLC and brain metastases.

Methods: This multicentre, single-arm, phase 2 trial was done across nine tertiary hospitals in China.

Cesium accumulation and plant growth promotion characteristics of A10 isolated from L. rhizosphere soil.

The combined microbial-plant remediation has increasingly been used to remediate heavy metal-contaminated soil. Some microorganisms could enhance phytoremediation efficiency by solubilizing heavy metal and improve plant growth by producing phytohormones in the heavy metal contaminated soils. In the present study, a strong cesium (Cs)-tolerant fungal strain was identified from soil microorganisms contaminated with Cs, and the enrichment conditions for Cs were optimized.

Efficacy and safety of hypomethylating agents in the treatment of AML/MDS patients relapsed post allogenetic hematopoietic stem cell transplantation.

Introduction: Acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) constitute myeloid malignancies, and allogeneic hematopoietic stem cell transplantation (allo-HSCT) is considered as a potentially optimal approach for achieving a long term cure. However, post-allo-HSCT relapse remains a leading cause of mortality and therapeutic failure.

Methods: To evaluate the efficacy and safety of combining hypomethylating agents (HMAs) with Bcl-2 inhibitors in the treatment of AML/MDS relapse following allo-HSCT, we retrospectively collected data from 42 patients who experienced relapse between April 2012 and March 2022 at Peking University First Hospital.

Optimal timing of anti-PD-1 antibody combined with chemotherapy administration in patients with NSCLC.

Background: Anti-programmed cell death 1 (PD-1) antibody combined with chemotherapy simultaneously is regarded as the standard treatment for patients with advanced non-small cell lung cancer (NSCLC) by current clinical guidelines. Different immune statuses induced by chemotherapy considerably affect the synergistic effects of the chemo-anti-PD-1 combination. Therefore, it is necessary to determine the optimal timing of combination treatment administration.

Pleiotropically activation of azaphilone biosynthesis by overexpressing a pathway-specific transcription factor in marine-derived Aspergillus terreus RA2905.

The genome sequencing of Aspergillus terreus reveals that the vast number of predicted biosynthetic gene clusters have not reflected by the metabolic profile observed under conventional culture conditions. In this study, a silent azaphilone biosynthetic gene cluster was activated by overexpressing a pathway-specific transcription factor gene2642 in marine-derived fungus A. terreus RA2905.

Enhancing the performance of a lithium-sulfur battery with spatially confined mesoporous nanoreactors in sulfurized polyacrylonitrile cathodes.

Sulfurized polyacrylonitrile (SPAN), which is recognized as a promising cathode material for lithium-sulfur batteries (Li-SBs), effectively mitigates the shuttle effect resulting from polysulfide dissolution. However, conventional SPAN cathodes typically exhibit sulfur loadings below 40 wt%. While encapsulation of sulfur within pores via a solid electrolyte interface addresses the low sulfur loading issue, the suboptimal kinetics of the solid-solid reactions hinder effective utilization of sulfur within the pores.

The spatiotemporal analysis of SARS-CoV-2 transmission in China since the termination of the dynamic zero-COVID policy.

China's dynamic zero-COVID policy has effectively curbed the spread of SARS-CoV-2, while inadvertently creating immunity gaps within its population. Subsequent surges in COVID-19 cases linked to various SARS-CoV-2 lineages post-policy termination necessitate a thorough investigation into the epidemiological landscape. This study addresses this issue by analyzing a comprehensive dataset of 39,456 high-quality genomes collected nationwide over an 11-month period since policy termination.
