Dental pulp stem cells alleviate Schwann cell pyroptosis via mitochondrial transfer to enhance facial nerve regeneration.

Dental pulp stem cells (DPSCs) have demonstrated remarkable potential in enhancing peripheral nerve regeneration, though the precise mechanisms remain largely unknown. This study investigates how DPSCs alleviate Schwann cell pyroptosis and restore mitochondrial homeostasis through intercellular mitochondrial transfer. In a crab-eating macaque model, we first observed that DPSC-loaded nerve conduits significantly promoted long-term nerve regeneration, facilitating tissue proliferation and myelin recovery.

Impact of white matter hyperintensity location on outcome in acute ischemic stroke patients: a lesion-symptom mapping study.

Background: Studies on the impact of white matter hyperintensity (WMH) on function outcome have primarily concentrated on WMH volume, overlooking the potential significance of WMH location.

Materials And Methods: Consecutive patients with ischemic stroke were retrospectively enrolled and classified into internal BZ (IBZ) infarct, cortical BZ (CBZ) infarct and mixed-type infarct patients.

The NSCLC immunotherapy response predicted by tumor-infiltrating T cells via a non-invasive radiomic approach.

Introductions: Identifying patients with non-small cell lung cancer (NSCLC) who are optimal candidates for immunotherapy is a cornerstone in clinical decision-making. The tumor immune microenvironment (TIME) is intricately linked with both the prognosis of the malignancy and the efficacy of immunotherapeutic interventions. CD8+ T cells, and more specifically, tissue-resident memory CD8+ T cells [CD8+ tissue-resident memory T (TRM) cells] are postulated to be pivotal in orchestrating the immune system's assault on tumor cells.

Epithelium/imcDC2 axis facilitates the resistance of neoadjuvant anti-PD-1 in human NSCLC.

Methods: Multi-omics analysis, including mass cytometry, single-cell RNA-seq, bulk RNA-seq, and polychromatic flow cytometry, was conducted using the resected tumor samples in a cohort of non-small cell lung cancer (NSCLC) patients received neoadjuvant anti-PD-1 therapy.

Risk Factors Associated With Inferior Alveolar Nerve Injury After Extraction of Impacted Lower Mandibular Third Molars: A Prospective Cohort Study.

Background: Inferior alveolar nerve (IAN) injury is one of the complications of impacted lower mandibular third molar (LM3) extraction. Given the unknown prognosis of IAN injuries and limited treatment options, it is critical to understand the risk factors of IAN injury before LM3 extraction.

Purpose: The purpose of the study was to identify risk factors associated with IAN injury after LM3 extraction.

Dental Pulp Stem Cell-Derived Exosomes Promote Sciatic Nerve Regeneration via Optimizing Schwann Cell Function.

Repair strategies for injured peripheral nerve have achieved great progresses in recent years. However, the clinical outcomes remain unsatisfactory. Recent studies have found that exosomes secreted by dental pulp stem cells (DPSC-exos) have great potential for applications in nerve repair.

Targeting pro-inflammatory T cells as a novel therapeutic approach to potentially resolve atherosclerosis in humans.

Atherosclerosis (AS), a leading cause of cardio-cerebrovascular disease worldwide, is driven by the accumulation of lipid contents and chronic inflammation. Traditional strategies primarily focus on lipid reduction to control AS progression, leaving residual inflammatory risks for major adverse cardiovascular events (MACEs). While anti-inflammatory therapies targeting innate immunity have reduced MACEs, many patients continue to face significant risks.

Adult-type rhabdomyoma of the lung: A case report.

Adult rhabdomyoma is an uncommon and benign striated muscle tumor consisting of striated muscular tissue. This neoplasm usually originates from cardiac muscle, and extracardiac rhabdomyoma is extremely rare. Herein, we report a case of adult rhabdomyoma in the lung, which has only been reported once in the 1970s.

Study on the Role and Mechanism of Exosomes Derived from Dental Pulp Stem Cells in Promoting Regeneration of Myelin Sheath in Rats with Sciatic Nerve Injury.

The prognosis of peripheral nerve injury (PNI) is usually poor, and currently, there is no effective treatment for PNI. Studies have shown that exosomes derived from mesenchymal stem cells could promote nerve regeneration by optimizing the function of endogenous Schwann cells (SCs), while the mechanism is unclear. Autophagy, a highly conserved intracellular catabolic process responsible for maintaining cellular homeostasis, has been proved to be involved in the regulation of nerve repair after injury.

Low carbon city and FDI inflows: evidence from China.

Achieving the goals of "carbon peaking" and "carbon neutrality" becomes one of the important elements of the ecological civilization strategy in China. Based on the strong balanced panel data of 281 prefecture-level cities in China from 2006 to 2019, we investigate the impact of Low-carbon city pilot policy (LCCP policy) on FDI inflows by using the multi-period DID model and intermediary model. After that, we discuss the heterogenous impact in terms of both policy tools and geographic locations.

Neoadjuvant radiotherapy plus single-incision thoracoscopic surgery in the treatment of type B3 thymomas.

Background: Although minimally invasive surgery is the standard treatment for thymomas, minimally invasive thymectomy is difficult for patients with type B3 thymomas, especially for giant or aggressive lesions. These tumors are frequently treated with radical radiation therapy or surgery plus adjuvant radiotherapy. Few studies, however, have tested the efficacy of neoadjuvant radiotherapy prior to thoracoscopic surgery.

Neoadjuvant target therapy with ensartinib in lung adenocarcinoma with EML4-ALK fusion variant: a case report and literature review.

Although neoadjuvant target therapy has been used to treat patients with non-small-cell lung cancer (NSCLC), most of these patients have mutations in the epidermal growth factor receptor (EGFR) gene. Few patients to date have received neoadjuvant target therapy for NSCLC containing variants in genes encoding anaplastic lymphoma kinase-tyrosine kinase inhibitors (ALK-TKIs). Herein, we present a 51-year-old man with a lung mass in the left lower lobe with enlarged mediastinal lymph nodes.
