Importance Comorbidities and genetic correlations between gastrointestinal tract diseases psychiatric disorders have been widely reported, with the gut-brain axis (GBA) hypothesized as a potential biological basis. However, degree to which shared determinants are involved in these associations underlying GBA is unclear. Objective To investigate etiology identify genomic loci, genes, pathways. Design, Setting, Participants This genome-wide pleiotropic association study using summary...

The current genome-wide association study (GWAS) of Lewy body dementia (LBD) suffers from low power due to a limited sample size. In addition, the genetic determinants underlying LBD and shared etiology with Alzheimer's disease (AD) Parkinson's (PD) remain poorly understood.Using largest GWAS summary statistics date (2591 cases 4027 controls), late-onset AD (86,531 676,386 PD (33,674 449,056 we comprehensively investigated basis among LBD, AD, PD. We first conducted correlation analysis...

Conditional image generation plays a vital role in medical analysis as it is effective tasks such super-resolution, denoising, and inpainting, among others. Diffusion models have been shown to perform at state-of-the-art level natural generation, but they not thoroughly studied with specific conditions. Moreover, current their own problems, limiting usage various tasks. In this paper, we introduce the use of conditional Denoising Probabilistic Models (cDDPMs) for which achieve performance on several

Mendelian randomization (MR) is a common tool for identifying causal risk factors underlying diseases. Here, we present method, MR with automated instrument determination (MRAID), effective analysis. MRAID borrows ideas from fine-mapping analysis to model an initial set of candidate single-nucleotide polymorphisms that are in potentially high linkage disequilibrium each other and automatically selects among them the suitable instruments inference. also explicitly models both uncorrelated...

Abstract Objectives To investigate the influence of patient's position on entry embolized air into systemic circulation after embolism (AE). Materials and methods 116 patients with AE were selected as study subjects, including 81 undergoing CT-guided transthoracic biopsy 35 localization pulmonary nodule before video-assisted thoracoscopic surgery. While maintaining original position, 94 out underwent at least one follow-up CT within 5 to 15 minutes AE. The following two situations considered...

Nanoporous gold freestanding films (NPG FSFs) have been fabricated via overgrowth of onto self-assembled monolayers nanocrystals at planar fluid–fluid interfaces. The resulting NPG FSFs are ligand-free on their surfaces and sizes can be as large several cm2. fairly mechanically robust; effective Young's moduli the order about 10 GPa. exhibit efficient electrocatalytic activity for methanol oxidation with an excellent electrochemical endurance, which is attributed to presence high-index...

Background This Mendelian randomization study aims to investigate causal associations between genetically predicted insomnia and 14 cardiovascular diseases (CVDs) as well the potential mediator role of 17 cardiometabolic risk factors. Methods Results Using genetic association estimates from large genome-wide studies UK Biobank, we performed a 2-sample analysis estimate with CVD conditions in primary analysis. Then mediation was conducted explore factors using network design. After correcting...

Diffusion models have achieved impressive performance on various image generation tasks, including super-resolution. Despite their performance, diffusion suffer from high computational costs due to the large number of denoising steps. In this paper, we proposed a novel accelerated model, termed Partial Models (PDMs), for magnetic resonance imaging (MRI) We observed that latents diffusing pair low- and high-resolution images gradually converge become indistinguishable after certain noise...

Prostate adenocarcinoma is one of the leading adult malignancies. Identification multiple causative biomarkers necessary and helpful for determining occurrence prognosis prostate adenocarcinoma. We aimed to identify potential prognostic genes in microenvironment estimate causal effects simultaneously. obtained gene expression data from TCGA project identified differentially expressed based on immune-stromal components. Among these genes, 68 were associated with biochemical recurrence at 3...
