Determinants of cerebrospinal fluid leakage in a large cohort of macroprolactinomas.

Background: Non-functional adrenal incidentaloma (NFAI) is associated with increased risk of adverse cardiometabolic outcome. Identifying predictors of atherosclerotic cardiovascular disease (ASCVD) may enable more appropriate management strategies in patients with NFAI. We aimed to investigate body composition parameters and ASCVD risk in patients with NFAI.

The cardiac blood transcriptome predicts de novo onset of atrial fibrillation in heart failure.

Heart failure (HF) increases the risk of developing atrial fibrillation (AF), leading to increased morbidity and mortality. Therefore, better prediction of this risk may improve treatment strategies. Although several predictors based on clinical data have been developed, the establishment of a transcriptome-based predictor of AF incidence in HF has proven to be more problematic.

Development and routine implementation of deep learning algorithm for automatic brain metastases segmentation on MRI for RANO-BM criteria follow-up.

Rationale And Objectives: The RANO-BM criteria, which employ a one-dimensional measurement of the largest diameter, are imperfect due to the fact that the lesion volume is neither isotropic nor homogeneous. Furthermore, this approach is inherently time-consuming. Consequently, in clinical practice, monitoring patients in clinical trials in compliance with the RANO-BM criteria is rarely achieved.

Intracerebroventricular anaerobic dopamine in Parkinson's disease with L-dopa-related complications: a phase 1/2 randomized-controlled trial.

Continuous compensation for cerebral dopamine deficiency represents an ideal treatment for Parkinson's disease. Dopamine does not cross the digestive and blood-brain barriers and is rapidly oxidized. The new concept is the intracerebroventricular administration of anaerobic dopamine (A-dopamine) using an abdominal pump connected to a subcutaneous catheter implanted in the third ventricle, near the striatum.

Study of Interactions Between Gadolinium-Based Contrast Agents and Collagen by Taylor Dispersion Analysis and Frontal Analysis Continuous Capillary Electrophoresis.

Background: Gadolinium-based contrast agents (GBCA) are widely used in magnetic resonance imaging (MRI) to enhance image contrast by interacting with water molecules, thus improving diagnostic capabilities. However, understanding the residual accumulation of GBCA in tissues after administration remains an area of active research. This highlights the need for advanced analytical techniques capable of investigating interactions between GBCAs and biopolymers, such as type I collagen, which are abundant in the body.

Temporal Stages of Burnout: How to Design Prevention?

Burnout, a major concern defined most commonly in the literature with a symptoms-based classification, can also be described as a temporal process with various stages experienced by workers, each composed of unique characteristics and challenges. This intricate process of burnout emphasizes pivotal moments, such as engagement and enthusiasm with a high job ideal (Stage 0), weakening of the ideal (Stage 1), protective withdrawal (Stage 2) and confirmed burnout (Stage 3). Through an opinion review, the objective of this article is to examine which prevention level, and more specifically which prevention actions, can be developed at each stage of this temporal process of burnout.

Aspartate signalling drives lung metastasis via alternative translation.

Lung metastases occur in up to 54% of patients with metastatic tumours. Contributing factors to this high frequency include the physical properties of the pulmonary system and a less oxidative environment that may favour the survival of cancer cells. Moreover, secreted factors from primary tumours alter immune cells and the extracellular matrix of the lung, creating a permissive pre-metastatic environment primed for the arriving cancer cells.

Impact of obesity on tolerance and persistence of statins in patients within 3months following an acute myocardial infarction: A real-world study.

Background: Recommended treatment after acute coronary syndrome (ACS) involves high-intensity statin therapy to achieve the low-density lipoprotein (LDL-C) target of<1.4mmol/L (European guidelines), but many patients discontinue statins because of real or perceived side-effects. Whether body mass index (BMI) influences statin intolerance remains unclear.

MicroGlycoDB: A database of microbial glycans using Semantic Web technologies.

Glycoconjugates are present on microbial surfaces and play critical roles in modulating interactions with the environment and the host. Extensive research on microbial glycans, including elucidating the structural diversity of the glycan moieties of glycoconjugates and polysaccharides, has been carried out to investigate the function of glycans in modulating the interactions between the host and microbes, to explore their potential applications in the therapeutic targeting of pathogenic species, and in the use as probiotics in gut microbiomes. However, glycan-related information is dispersed across numerous databases and a vast amount of literature, which makes it laborious and time-consuming to identify and gather the relevant information about microbial glycosylation.

Law and Order of Colloidal Tectonics: From Molecules to Self-Assembled Colloids.

Since biochemists and biologists have progressed in understanding the mechanisms involved in living organisms, biological systems have become a source of inspiration for chemists. In this context, the concept of colloidal tectonics, describing the spontaneous formation of colloidal particles or supracolloidal structures in which the building blocks are called "tectons", has emerged. Therefore, a bottom-up edification of tectons towards (supra) colloidal structures is allowed.

CYP3A4-Mediated Bioactivation of the β-Amyloid Precursor Protein-Cleaving Enzyme 1 Inhibitor JNJ-54861911 Results in Redox-Neutral Addition of Glutathione via Catalysis by Glutathione S-Transferase α1, Identified as the Major Target Protein in Human Hepatocytes.

The β-amyloid precursor protein-cleaving enzyme 1 (BACE1) inhibitor JNJ-54861911, a candidate for the treatment of Alzheimer's disease, was withdrawn from clinical trials due to drug-induced liver injury (DILI). This paper describes our investigation of the metabolism of JNJ-54861911 to understand the potential contribution to the observed DILI. In human hepatocytes, JNJ-54861911 is metabolized by CYP450 3A4 to a reactive intermediate (RI), which undergoes glutathione (GSH) addition at C6 of the 2-amino-4-methyl-1,3-thiazin-4-yl moiety via glutathione S-transferase α1 (GSTA1) catalysis.

ProPickML: Advancing Clinical Diagnostics with Automated Peak Picking in Label-Free Targeted Proteomics.

In targeted proteomics utilizing Selected Reaction Monitoring (SRM), the precise detection of specific peptides within complex mixtures remains a significant challenge, particularly due to noise and interference in chromatograms. Existing methodologies, such as isotopic labeling and scoring algorithms, offer partial solutions but are constrained by high run times and elevated false discovery rates. To address these limitations, we have developed ProPickML a machine learning-based tool designed to accurately identify peptide peaks across diverse data sets, independent of the assumed presence of the peptide.

New discoveries in bile acids, gut microbiota and host interactions in health and diseases.

Over the past 20 years, basic research has robustly demonstrated the regulatory role of bile acids in physiological processes, primarily by the discovery and the study of their specific receptors and the understanding of the pathways they modulate. The dysregulation of the bile acid pool and the perturbation of bile acid signaling have been implicated in the pathophysiology of various clinical conditions, including cardiometabolic, cholestatic and inflammatory diseases. Consequently, bile acids have emerged as promising therapeutic targets, with compounds to modulate bile acid metabolism and signaling being actively investigated in pre-clinical and clinical settings.

Differential stress responsiveness determines intraspecies virulence heterogeneity and host adaptation in Listeria monocytogenes.

Microbial pathogenesis is mediated by the expression of virulence genes. However, as microbes with identical virulence gene content can differ in their pathogenic potential, other virulence determinants must be involved. Here, by combining comparative genomics and transcriptomics of a large collection of isolates of the model pathogen Listeria monocytogenes, time-lapse microscopy, in vitro evolution and in vivo experiments, we show that the individual stress responsiveness of L.
