Background: Endotoxin-induced Acute Lung Injury (ALI) is a severe clinical syndrome with limited treatment. Oxycodone can alleviate the endotoxin-induced ALI, but the exact mechanism remains unclear. The previous study showed that Heme Oxygenase-1 (HO-1) plays a protective role against endotoxin-induced ALI by regulating mitophagy.

Enhanced regenerative and developmental potential of embryonal and stem cell-derived platelets compared to adult platelets.

The molecular features and multifaceted roles of platelets have been well characterized in adult mammals, but little is known about platelets at earlier developmental stages. In this study, we conduct transcriptomic and proteomic profiling of mouse embryonic platelets and find that, compared to adult platelets, they exhibit reduced classic immune-regulatory and procoagulant features but enhanced development-supporting traits. Notably, embryonic platelets interact more robustly with various cell types, including fibroblasts, and significantly accelerate refractory wound healing.

Spatial distribution of enlarged perivascular spaces as a potential biomarker for distinguishing vascular dementia from Alzheimer's disease in older adults.

Efficacy of Intravenous Tenecteplase Bridge Thrombectomy for Recurrent Ischemic Stroke Within 3 Months: A Case Report.

In the previous guideline recommendations, patients who have had a stroke within 3 months are excluded from intravenous thrombolysis (IVT) regimens. Some studies have suggested that IVT with alteplase (rt-PA) may be effective and safe in such patients, but evidence supporting the use of tenecteplase (TNK) is not sufficient. This paper includes an 80-year-old male patient readmitted for recurrence of ischaemic stroke (IS) after 48 days, who received TNK IVT as a bridging therapy prior to thrombectomy, with favourable results at 8-week follow-up.

Investigating Raman peak enhancement in carboxyl-rich molecules: insights from Au@Ag core-shell nanoparticles in colloids.

Surface-enhanced Raman scattering (SERS) is a promising analytical technique with applications in environmental monitoring, healthcare, and the biopharmaceutical industry. While SERS has been successfully applied to molecules such as 4-mercaptobenzoic acid and other thiol- and amine-containing compounds, there is limited research on its detection capabilities for molecules rich in carboxyl groups or unsaturated bonds, such as citric acid. This study investigates the SERS enhancement of Au@Ag core-shell nanoparticles in response to citric acid and other molecules with carboxyl and unsaturated bonds.

Tumor cell-derived N-acetyl-aspartyl-glutamate reshapes the tumor microenvironment to facilitate breast cancer metastasis.

Neurotransmitters are increasingly recognized to play important roles in limiting anti-tumor immunity. N-acetyl-aspartyl-glutamate (NAAG) has been extensively studied in neurological disorders; however, its potential role in restricting anti-tumor immunity has not been investigated. Here, we demonstrated that NAAG or its synthetase RimK-like family member B (RIMKLB) significantly disrupted anti-tumor immunity by rewiring the myeloid progenitor differentiation of polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs), which in turn promoted breast cancer growth and metastasis.

Unraveling the peripheral nervous System's role in tumor: A Double-edged Sword.

The peripheral nervous system (PNS) includes all nerves outside the brain and spinal cord, comprising various cells like neurons and glial cells, such as schwann and satellite cells. The PNS is increasingly recognized for its bidirectional interactions with tumors, exhibiting both pro- and anti-tumor effects. Our review delves into the complex mechanisms underlying these interactions, highlighting recent findings that challenge the conventional understanding of PNS's role in tumorigenesis.

Rapidly Manufactured CAR-T with Conserved Cell Stemness and Distinctive Cytokine-Secreting Profile Shows Improved Anti-Tumor Efficacy.

The emergence of chimeric antigen receptor T-cell (CAR-T) immunotherapy holds great promise in treating hematologic malignancies. While advancements in CAR design have enhanced therapeutic efficacy, the time-consuming manufacturing process has not been improved in the commercial production of CAR-T cells. In this study, we developed a "DASH CAR-T" process to manufacture CAR-T cells in 72 h and found the excelling anti-tumor efficacy of DASH CAR-T cells over conventionally manufactured CAR-T cells.

L3MBTL3 and STAT3 collaboratively upregulate SNAIL expression to promote metastasis in female breast cancer.

The STAT3 pathway promotes epithelial-mesenchymal transition, migration, invasion and metastasis in cancer. STAT3 upregulates the transcription of the key epithelial-mesenchymal transition transcription factor SNAIL in a DNA binding-independent manner. However, the mechanism by which STAT3 is recruited to the SNAIL promoter to upregulate its expression is still elusive.
