Background Tuberous sclerosis complex (TSC) is a multisystem genetic disorder primarily characterized by the development of benign tumors in multiple organs. While cardiovascular involvement less common than neurological or renal manifestations, it typically presents with cardiac rhabdomyomas (CRs). The co-occurrence bicuspid aortic valve (BAV) TSC exceedingly rare. Case summary We report case 26-year-old woman genetically confirmed TSC, harboring novel pathogenic variant TSC2 gene....
A RadioFrequency Quadrupole (RFQ) cooler-buncher system has been developed and implemented in a collinear laser spectroscopy setup. This is dedicated to convert continuous ion beam into short bunches, while enhancing quality reducing energy spread. The functionality of the RFQ verified through offline tests with stable rubidium indium beam, delivered from surface source ablation source, respectively. With transmission efficiency exceeding 60%, bunched beams full width at half maximum...
Abstract Background and aims Recent studies have suggested an interplay between conicity index (C-index)-related diabetes risk lipid burden. It is plausible that the atherogenic of plasma (AIP), fatty liver, HbA1c mediate association C-index risk, though this has not been fully explored. This study explored whether AIP, relationship as well their combined effect. Methods Data from 15,453 participants in NAGALA Cohort were analyzed (median follow-up 5.39 years). Restricted Cubic Spline (RCS)...
In this study, we investigated the therapeutic effects and mechanisms of umbilical cord mesenchymal stem cells (UCMSCs) in diabetic nephropathy (DN) ZDF (FA/FA) rats. The were assessed by renal function tests, urinary albumin-creatinine ratio, PAS staining, electron microscopy, TGF-β1 expression tissue. Subsequently, podocyte injury tissue was detected immunofluorescence staining for podocin. To further explore underlying mechanism, serum Angptl4 levels measured, Angptl4, integrin β3,...
Abstract Quasi-periodic pulsation (QPP) is a common phenomenon in solar flares. Studying QPP important to further our understanding of the physical processes operating However, detection complicated by presence noise flaring lightcurves. In this study, we apply Bayesian-based Markov-Chain-Monte-Carlo (MCMC) technique detection. We use MCMC fit Fourier power spectral density (PSD) profiles lightcurves, aiming determine quasi-periodic component model comparison and test statistics. Two models...
Abstract We investigated oscillations in an M8.7 solar flare (SOL2014-10-22), including quasi-periodic pulsations (QPPs) light curves and Doppler shift the loops. Using Bayesian-based Markov Chain Monte Carlo, Fast Fourier Transform, wavelet analysis method, QPPs were identified at microwave hard X-ray wave bands during impulsive phase, dominant period is 40–50 s. They should be associated with a repetitive energy release process, which accelerates nonthermal electrons periodically. On other...
Abstract Solar images observed in different channels with instruments are crucial to the study of solar activity. However, have fields view, causing them be misaligned. It is essential accurately register for studying activity from multiple perspectives. Image registration described as an optimizing problem image registered a reference image. In this paper, we proposed novel coarse-to-fine method multichannel images. coarse step, used regular step gradient descent algorithm optimizer...
