Article Abstract

Common stochastic models of gene expression predict the gene-specific distribution of total mRNA per cell but lack subcellular resolution. Here, for a broad class of transcription initiation models, we derive an exact steady-state solution for the joint distribution of nuclear and cytoplasmic mRNA, and demonstrate that fitting this solution to spatially resolved mRNA data enhances parameter identifiability. By accounting for extrinsic noise, we use the model to precisely quantify bursty expression across thousands of human genes and link it to their biological functions.

The aim of this study was to assess the prevalence of temporomandibular disorder (TMD) and associated factors in an adult population in southern Brazil. The population-based sample (n = 4.65) included participants from Passo Fundo, a town in southern Brazil.

Surveillance monitoring of shallow groundwater revealed that redox conditions can vary on a small scale. Therefore, the aim of this study was to categorize redox conditions in the groundwater of Lower Saxony, Germany, and to analyze the spatial distribution and trends of parameters related to redox conditions during surveillance monitoring from 1957 to 2015 in Lower Saxony, Germany. Methodically, trends were considered by applying the Mann-Kendall test and redox conditions of groundwater were classified according to the scheme of Jurgens et al.

Causally Sound Priors for Binary Experiments.

Bayesian Anal

January 2025

Department of Statistics, University of Washington, Seattle, USA.

We introduce the BREASE framework for the Bayesian analysis of randomized controlled trials with binary treatment and outcome. Approaching the problem from a causal inference perspective, we propose parameterizing the likelihood in terms of the aseline isk, fficacy, and dverse ide ffects of the treatment, along with a flexible, yet intuitive and tractable jointly independent beta prior distribution on these parameters, which we show to be a generalization of the Dirichlet prior for the joint distribution of potential outcomes. Our approach has a number of desirable characteristics when compared to current mainstream alternatives: (i) it naturally induces prior dependence between expected outcomes in the treatment and control groups; (ii) as the baseline risk, efficacy and risk of adverse side effects are quantities commonly present in the clinicians' vocabulary, the hyperparameters of the prior are directly interpretable, thus facilitating the elicitation of prior knowledge and sensitivity analysis; and (iii) we provide analytical formulae for the marginal likelihood, Bayes factor, and other posterior quantities, as well as an exact posterior sampling algorithm and an accurate and fast data-augmented Gibbs sampler in cases where traditional MCMC fails.

Purpose: Autoimmune thyroiditis (AIT) is the most common organ-specific autoimmune disease, and its pathogenesis is closely related to the inflammatory microenvironment driven by immune cell penetration. The role of the newly proposed concept of PANoptosis in immune-related diseases is gradually being revealed. However, there is currently a lack of reports on PANoptosis in AIT.

Objectives: Bone scintigraphy is a sensitive imaging method to evaluate patients with suspected osteonecrosis. We assessed the diagnostic performance of combined bone single-photon emission computed tomography/computed tomography (SPECT/CT) (CBS) in patients with known rheumatic disease or other connective tissue disorders and clinical suspicion of osteonecrosis compared to magnetic resonance imaging (MRI).

Methods: This prospective diagnostic accuracy study included 70 patients with clinical suspicion of osteonecrosis in any bone who underwent a planar triple-phase bone scan along with a regional SPECT/CT (CBS) and regional MRI.
