Methods: Patients with M1 occlusion were selected from the ANGEL-ACT registry, which comprised 1793 individuals.

Association between stroke subtypes and outcomes of endovascular therapy: a post-hoc analysis of the ANGEL-ASPECT Trial.

Objectives: Our study aims to examine the value of endovascular therapy (EVT) and its comparison to medical management (MM) in ischaemic stroke patients accompanied by large artery atherosclerosis (LAA) and non-LAA METHODS: modified Rankin scale score (mRS) was evaluated at 90 days post the stroke attack and was considered as the primary outcome. Other outcomes measured in this study included score changes of 0-2 and 0-3 on the mRS. The occurrence of symptomatic intracranial haemorrhage at 24 hours after EVT was also measured as a safety endpoint.

Exploring the spatiotemporal effects of meteorological factors on hand, foot and mouth disease: a multiscale geographically and temporally weighted regression study.

The influence of meteorological factors on hand, foot, and mouth disease (HFMD) is not on the same scale, it's rare for previous studies to measure and recognize the independent regression relationship between each variable in space and time scale. This study used a multiscale geographically and temporally weighted regression (MGTWR) model to explore the relationship between the incidence of HFMD and related meteorological factors in Shandong Province, China, during 2015-2019 and attempted to quantify the influence of meteorological factors on HFMD under different spatiotemporal effects. Meanwhile, we used the Global Moran's I statistic and Local Moran's I statistic to test the spatial autocorrelation of the incidence of HFMD.

Spontaneous recanalization in acute large core ischemic stroke due to large vessel occlusion: a post-hoc analysis of the ANGEL-ASPECT trial.

Background: Previous studies have indicated that a subset of patients with acute ischemic stroke (AIS) due to large vessel occlusion (LVO) experience spontaneous recanalization (SR), but the prognosis and factors associated with SR in these individuals are not well characterized.

Methods: We conducted a post hoc secondary analysis of the Study of Endovascular Therapy in Acute Anterior Circulation Large Vessel Occlusive Patients with a Large Infarct Core (ANGEL-ASPECT) trial. SR in the medical management group was defined as a modified arterial occlusive lesion (AOL) grade of 2 or 3 on computed tomography angiography (CTA) or magnetic resonance angiography (MRA) at 36 hours (±12 hours).

METTL3-Mediated mA Modification of FMRP Drives Hepatocellular Carcinoma Progression and Indicates Poor Prognosis.

Methods: This is a post-hoc analysis of the Endovascular Therapy in Anterior Circulation Large Vessel Occlusion with a Large Infarct (ANGEL-ASPECT) randomized trial, which enrolled patients within 24 hours of onset with ASPECTS 3 to 5 or ASPECTS 0 to 2 with an infarct core 70 to 100 ml. Mismatch ratio was defined as time-to-maximum (T) >6 s cerebral volume/ischemic core volume, and mismatch volume was defined as T >6 s volume minus ischemic core volume.

Nucleic acid-induced NADase activation of a short Sir2-associated prokaryotic Argonaute system.

Inhibition of nucleic acid targets is mediated by Argonaute (Ago) proteins guided by RNA or DNA. Although the mechanisms underpinning the functions of eukaryotic and "long" prokaryotic Ago proteins (pAgos) are well understood, those for short pAgos remain enigmatic. Here, we determine two cryoelectron microscopy structures of short pAgos in association with the NADase-domain-containing protein Sir2-APAZ from Geobacter sulfurreducens (GsSir2/Ago): the guide RNA-target DNA-loaded GsSir2/Ago quaternary complex (2.

IL-17a promotes hepatocellular carcinoma by increasing FAP expression in hepatic stellate cells via activation of the STAT3 signaling pathway.

Studies have shown that hepatic stellate cells (HSCs) and interleukin-17a (IL-17a) play important roles in liver tumorigenesis. In addition, fibroblast activation protein-α (FAP) has been shown to be a key regulator of hepatic stellate cell activation. In this study, in vivo and in vitro experiments were performed to verify the promoting effects of IL-17a administration, IL-17a overexpression, and FAP upregulation in HSCs on liver fibrosis and liver tumorigenesis.
