Intra-Arterial Tenecteplase Following Endovascular Reperfusion for Large Vessel Occlusion Acute Ischemic Stroke: The POST-TNK Randomized Clinical Trial.

Importance: The impact of adjunctive intra-arterial tenecteplase administration following near-complete to complete reperfusion by endovascular thrombectomy (EVT) for acute ischemic stroke is unknown.

Objective: To assess the efficacy and adverse events of adjunctive intra-arterial tenecteplase in patients with large vessel occlusion stroke who had achieved near-complete to complete reperfusion (defined as a score on the expanded Thrombolysis in Cerebral Infarction [eTICI] scale of 2c to 3) after EVT.

Design, Setting, And Participants: Investigator-initiated, randomized, open-label, blinded outcome assessment trial implemented at 34 hospitals in China among 540 patients with stroke due to proximal intracranial large vessel occlusion within 24 hours of the time they were last known to be well, with an eTICI score of 2c to 3 after EVT, and without prior intravenous thrombolysis.

Decreased attenuation difference between non-contrast and portal-venous phases of CT predicts the ultrasonography-unspecified adnexal torsion.

Mechanism of effect and therapeutic potential of NLRP3 inflammasome in spinal cord injury.

Spinal cord injury (SCI) is a serious and disabling central nervous system injury that can trigger various neuropathological conditions, resulting in neuronal damage and release of various pro-inflammatory mediators, leading to neurological dysfunction. Currently, surgical decompression, drugs and rehabilitation are primarily used to relieve symptoms and improve endogenous repair mechanisms; however, they cannot directly promote nerve regeneration and functional recovery. SCI can be divided into primary and secondary injuries.

DAPK enhances DDX20 protein stability via suppression of TRIM25-mediated ubiquitination-based DDX20 degradation.

We have previously found that the DAPK-DDX20 signaling axis exerts an anti-cancer activity in hepatocellular carcinoma (HCC) by inhibiting the GTPase activity of CDC42, thereby reducing the invasive and migratory capabilities of cancer cells without affecting cell proliferation. DDX20 serves as an intermediate protein regulated by DAPK in the control of CDC42. Specifically, DAPK enhances DDX20 protein levels by suppressing DDX20 degradation.

MAPK signaling pathway in spinal cord injury: Mechanisms and therapeutic potential.

Spinal cord injury (SCI) is a severe disabling injury of the central nervous system that can lead to motor, sensory, and autonomic dysfunction below the level of the injury. According to its pathophysiological process, SCI can be divided into primary injury and secondary injury. Currently, multiple therapeutic strategies have been proposed to alleviate secondary injury and overcome the occurrence of neurodegenerative events.

Hypoxia adaptation mechanism in rats' peripheral auditory system in high altitude migration: a time series transcriptome analysis.

High altitude is characterized by low oxygen, low pressure, and high radiation. When migrates from low to high altitudes, the body's tissues and organs experience hypoxic stress and will present acoustic adaptation as the protective response. However, the mechanisms of acoustic adaptation at high altitudes remain unclear.

Background: Recurrent spontaneous abortion (RSA) is a common complication during pregnancy, which is a burden to patients both physically and mentally. Circular RNAs (circRNAs) play important roles in RSA. However, the roles of circDDX21 in RSA development remain unknown.

Spatial Heterogeneity of PD-1/PD-L1 Defined Osteosarcoma Microenvironments at Single-Cell Spatial Resolution.

Osteosarcoma, predominantly affecting children and adolescents, is a highly aggressive bone cancer with a 5-year survival rate of 65% to 70%. The spatial dynamics between tumor-associated macrophage (TAM) and other cellular subtypes, including T cells, osteoblasts, and osteoclasts, are critical for understanding the complexities of the osteosarcoma tumor microenvironment (TME) and can provide insights into potential immunotherapeutic strategies. Our study employs a pioneering approach that combines deep learning-based digital image analysis with multiplex fluorescence immunohistochemistry to accurately implement cell detection, segmentation, and fluorescence intensity measurements for the in-depth study of the TME.

Epigenetic modifications of inflammation in spinal cord injury.

Spinal cord injury (SCI) is a central nervous system injury that leads to neurological dysfunction or paralysis, which seriously affects patients' quality of life and causes a heavy social and economic burden. The pathological mechanism of SCI has not been fully revealed, resulting in unsatisfactory clinical treatment. Therefore, more research is urgently needed to reveal its precise pathological mechanism.

Treatment of HER2-Positive Breast Cancer with Brain Metastases Using Anlotinib and Trastuzumab Deruxtecan: A Case Report.

Breast cancer with brain metastasis accounts for the second largest number of brain metastases among solid malignancies. Despite advances in HER2-targeted therapy, 50% of patients with human epidermal growth factor receptor 2-positive (HER2+) breast cancer develop brain metastases and are associated with poor outcomes. In this article, we report the case of a patient with HER2+ metastatic breast cancer who developed brain metastases, despite experiencing a durable effect on extracranial metastases after treatment with trastuzumab and pertuzumab.

Cystic Fibrosis: Understanding Cystic Fibrosis Transmembrane Regulator Mutation Classification and Modulator Therapies.

A common life-threatening hereditary disease, Cystic Fibrosis (CF), affects primarily Caucasian infants. High sweat-salt levels are observed as a result of a single autosomal mutation in chromosome 7 that affects the critical function of the cystic fibrosis transmembrane regulator (CFTR). For establishing tailored treatment strategies, it is important to understand the broad range of CFTR mutations and their impacts on disease pathophysiology.

Silibinins and curcumin as promising ligands against mutant cystic fibrosis transmembrane regulator protein.

Cystic Fibrosis Transmembrane Regulator (CFTR) is a significant protein that is responsible for the movement of ions across cell membranes. The cystic fibrosis (CF) occur due to the mutations in the CFTR gene as it produces the dysfunctional CFTR protein. The sequence of CFTR protein as a target structure was retrieved from UniProt and PDB database.
