Similarly, murine myoblasts overexpressing a catalytically inactive TRIM32 mutant aberrantly accumulate α- and β-dystroglycan and α-sarcoglycan. We speculate that the stoichiometric loss of costamere components disrupts costamere complexes to promote muscle degeneration.Spatial reorganization of cytoplasm in zygotic cells is critically important for establishing the body plans of many animal species. In ascidian zygotes, maternal determinants (mRNAs) are first transported to the vegetal pole a few minutes after fertilization and then to the future posterior side of the zygotes in a later phase of cytoplasmic reorganization, before the first cell division. Here, by using a novel fluorescence polarization microscope that reports the position and the orientation of fluorescently labeled proteins in living cells, we mapped the local alignments and the time-dependent changes of cortical actin networks in Ciona eggs. The initial cytoplasmic reorganization started with the contraction of vegetal hemisphere approximately 20 s after the fertilization-induced [Ca2+] increase. Timing of the vegetal contraction was consistent with the emergence of highly aligned actin filaments at the cell cortex of the vegetal hemisphere, which ran perpendicular to the animal-vegetal axis. We propose that the cytoplasmic reorganization is initiated by the local contraction of laterally aligned cortical actomyosin in the vegetal hemisphere, which in turn generates the directional movement of cytoplasm within the whole egg.To analyze the type, etiology, clinical features and prognosis of stroke in southern China diabetic patients. From January to August 2019, acute stroke patients were prospectively enrolled in the Wenzhou Stroke Registry within 7 days of admission to the Hospital. The differences between the 2 groups of stroke patients with or without diabetes were in the following aspects bleeding site of hemorrhagic stroke, different ischemic stroke etiology, Oxfordshire Community Stroke Project (OCSP) classification, death and disability within 3 months. Of the 497 patients enrolled, 104 (20.9%) were diabetic patients. 114(22.9%) patients had hemorrhagic stroke. The incidence of hemorrhagic stroke in the diabetic group was 10.6%, deep hemorrhage stroke account for 90.9%.In patients with ischemic stroke, the proportions of the new Trial of Org 10172 in Acute Stroke Treatment (TOAST) etiological subtype classifications (atherothrombosis (AT), cardioembolism (CE), small artery disease (SAD), stroke of other determined etiology (SOD) and stroke of undetermined etiology (SUD)) in the diabetic (non-diabetic) group was 43% (31%), 7.5% (14.1%), 27.9% (16.9%), 1% (0.3%), and 20.4% (37.6%), respectively; the proportion of The OCSP classifications(total anterior circulation infarcts(TACI), partial anterior circulation infarcts(PACI), lacunar infarcts(LACI) and posterior circulation infarcts(POCI)) in the diabetic (non-diabetic) group was16.1% (22%), 30.1%(37.2%), 42% (31.4%), and 10.8% (9%), respectively. The 3-month poor prognosis of the diabetic and non-diabetic groups was 23.1% and 28.2%. For diabetic patients, the incidence of hemorrhagic stroke is low, deep hemorrhage is common; SAD and LACI are common in the ischemic stroke; There was no significant difference in the 3-month prognosis between the 2 groups.Amyloid beta (Aβ) is a major component of amyloid plaques, which are a key pathological hallmark found in the brains of Alzheimer's disease (AD) patients. We show that statins are effective at reducing Aβ in human neurons from nondemented control subjects, as well as subjects with familial AD and sporadic AD. Aβ is derived from amyloid precursor protein (APP) through sequential proteolytic cleavage by BACE1 and γ-secretase. While previous studies have shown that cholesterol metabolism regulates APP processing to Aβ, the mechanism is not well understood. We used iPSC-derived neurons and bimolecular fluorescence complementation assays in transfected cells to elucidate how altering cholesterol metabolism influences APP processing. Altering cholesterol metabolism using statins decreased the generation of sAPPβ and increased levels of full-length APP (flAPP), indicative of reduced processing of APP by BACE1. We further show that statins decrease flAPP interaction with BACE1 and enhance APP dimerization. Additionally, statin-induced changes in APP dimerization and APP-BACE1 are dependent on cholesterol binding to APP. Our data indicate that statins reduce Aβ production by decreasing BACE1 interaction with flAPP and suggest that this process may be regulated through competition between APP dimerization and APP cholesterol binding.
  To identify the value of radiomics method derived from CT images to predict prognosis in patients with COVID-19.
 
  A total of 40 patients with COVID-19 were enrolled in the study. Baseline clinical data, CT images, and laboratory testing results were collected from all patients. We defined that ROIs in the absorption group decreased in the density and scope in GGO, and ROIs in the progress group progressed to consolidation. A total of 180 ROIs from absorption group (
  = 118) and consolidation group (
  = 62) were randomly divided into a training set (
  = 145) and a validation set (
  = 35) (82). Radiomics features were extracted from CT images, and the radiomics-based models were built with three classifiers. A radiomics score (Rad-score) was calculated by a linear combination of selected features. The Rad-score and clinical factors were incorporated into the radiomics nomogram construction. The prediction performance of the clinical factors model and the radiomics nomogram for prognosis was estimated.
