Objective: Progression of prediabetes to type 2 diabetes has been associated with β-cell dysfunction, whereas its remission to normoglycemia has been related to improvement of insulin sensitivity. To understand the mechanisms and identify potential biomarkers related to prediabetes trajectories, we compared the proteomics and metabolomics profile of people with prediabetes progressing to diabetes or reversing to normoglycemia within 1 year.

Research Design And Methods: The fasting plasma concentrations of 1,389 proteins and the fasting, 30-min, and 120-min post-oral glucose tolerance test (OGTT) plasma concentrations of 152 metabolites were measured in up to 134 individuals with new-onset diabetes, prediabetes, or normal glucose tolerance.

Cardiac fibroblasts are activated following myocardial infarction (MI) and cardiac fibrosis is a major driver of the growing burden of heart failure. A non-invasive targeting method for activated cardiac fibroblasts would be advantageous because of their importance for imaging and therapy. Targeting was achieved by linking a 7-amino acid peptide (EP9) to a perfluorocarbon-containing nanoemulsion (PFC-NE) for visualization by F-combined with H-MRI.

Article Synopsis
  • Detecting circulating tumor cells (CTCs) is tough because they are present in low numbers and vary in characteristics, with traditional methods struggling for those with low EpCAM expression.
  • This study introduces a new approach using silica-coated magnetic nanobeads with streptavidin for better CTC capture.
  • The new method showed higher capture rates for specific cancer cell lines, especially those with low EpCAM expression, indicating its potential for improving CTC detection compared to existing commercial options.

Background: Depression is a serious health problem worldwide and is often associated with disability and reduced quality of life. In aging societies, early recognition of depression in older adults is highly relevant. Therefore, this study investigated the prevalence of depressive symptoms in individuals aged 50 and older with the aim to identify those at risk for major depression.

Electronic address:

Article Synopsis
  • Impaired calcium (Ca) handling in heart cells is a key feature of heart failure (HF), leading to issues like weakened heart contractions and irregular heartbeats.
  • The study used transgenic mice with a mutation affecting a calcium regulator (phospholamban) to understand how defects in calcium cycling contribute to HF, noting that these mice experience severe and fast-progressing heart failure.
  • Early treatment aimed at correcting calcium cycling using Raf kinase inhibitor protein (RKIP) was found to delay heart cell damage and improve overall health of the mice, indicating that addressing Ca dynamics early on could be crucial for preventing further complications in heart failure.

The athlete's paradox states that intramyocellular triglyceride accumulation associates with insulin resistance in sedentary but not in endurance-trained humans. Underlying mechanisms and the role of muscle lipid distribution and composition on glucose metabolism remain unclear. We compared highly trained athletes (ATHL) with sedentary normal weight (LEAN) and overweight-to-obese (OVWE) male and female individuals.

Environmental microbial reservoir influences the bacterial communities associated with Hydra oligactis.

Sci Rep

December 2024

MTA-DE "Momentum" Ecology, Evolution & Developmental Biology Research Group, Dept. of Evolutionary Zoology, University of Debrecen, Debrecen, Hungary.

The objective to study the influence of microbiome on host fitness is frequently constrained by spatial and temporal variability of microbial communities. In particular, the environment serves as a dynamic reservoir of microbes that provides potential colonizers for animal microbiomes. In this study, we analyzed the microbiome of Hydra oligactis and corresponding water samples from 15 Hungarian lakes to reveal the contribution of environmental microbiota on host microbiome.

Introduction: Very rarely, adult NMDAR antibody-associated encephalitis (NMDAR-E) leads to persistent cerebellar atrophy and ataxia. Transient cerebellar ataxia is common in pediatric NMDAR-E. Immune-mediated cerebellar ataxia may be associated with myelin oligodendrocyte glycoprotein (MOG), aquaporin-4 (AQP-4), kelch-like family member 11 (KLHL11), and glutamate kainate receptor subunit 2 (GluK2) antibodies, all of which may co-occur in NMDAR-E.

Simulated brain networks reflecting progression of Parkinson's disease.

Netw Neurosci

December 2024

Institute of Neurosciences and Medicine - Brain and Behaviour (INM-7), Research Centre Jülich, 52425 Jülich, Germany.

The neurodegenerative progression of Parkinson's disease affects brain structure and function and, concomitantly, alters the topological properties of brain networks. The network alteration accompanied by motor impairment and the duration of the disease has not yet been clearly demonstrated in the disease progression. In this study, we aim to resolve this problem with a modeling approach using the reduced Jansen-Rit model applied to large-scale brain networks derived from cross-sectional MRI data.

Background: The 313-variant polygenic risk score (PRS) provides a promising tool for clinical breast cancer risk prediction. However, evaluation of the PRS across different European populations which could influence risk estimation has not been performed.

Methods: We explored the distribution of PRS across European populations using genotype data from 94,072 females without breast cancer diagnosis, of European-ancestry from 21 countries participating in the Breast Cancer Association Consortium (BCAC) and 223,316 females without breast cancer diagnosis from the UK Biobank.

Background: Recurrent attacks in neuromyelitis optica spectrum disorders (NMOSDs) or myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) can lead to severe disability. We aimed to analyse the real-world use of immunotherapies in patients with NMOSD and MOGAD, focusing on changes in treatment strategies, effects on attack rates (ARR) and risk factors for attacks.

Methods: This longitudinal registry-based cohort study included 493 patients (320 with aquaporin-4 immunoglobulin G (AQP4-IgG) seropositive NMOSD (65%), 44 with AQP4-IgG seronegative NMOSD (9%) and 129 MOGAD (26%)) with 1247 treatments from 19 German and one Austrian centre from the registry of the neuromyelitis optica study group (NEMOS).

Photocaged compounds are chemical conjugates that are designed to release an active molecule upon exposure to light of a specific wavelength. In recent years, photocaged inducer molecules such as caged isopropyl β-D-1-thiogalactopyranoside (cIPTG) have been increasingly used as a powerful tool for light-driven gene expression in bacteria, allowing researchers to precisely and noninvasively tune the expression of specific target genes. In this chapter, we present a guideline for the synthesis of 6-nitropiperonyl photocaged IPTG (NP-cIPTG) as well as its in vivo application as an optochemical on-switch of gene transcription in Escherichia coli and other bacteria.

DZHK (German Center for Cardiovascular Research), Germany; Department of Internal Medicine/Cardiology, Heart Center Leipzig at the University of Leipzig, Leipzig, Germany; Helios Health Institute, Leipzig, Germany. Electronic address:

Background: The timing of coronary angiography in patients with successfully resuscitated out-of-hospital cardiac arrest and missing ST-segment elevations on the electrocardiogram has been investigated in 2 large randomized controlled trials, TOMAHAWK (Angiography After Out-of-Hospital Cardiac Arrest Without ST-Segment Elevation) and COACT (Coronary Angiography After Cardiac Arrest Trial). Both trials found neutral results for immediate vs delayed/selective coronary angiography on short-term all-cause mortality. The TOMAHAWK trial showed a tendency towards harm with immediate coronary angiography, though not statistically significant with traditional frequentist methods.
