The impact of eccentric muscle contractions on peripheral nerve integrity.

Eur J Appl Physiol

December 2024

Neuromuscular Research Lab, Faculty of Human Kinetics, University of Lisbon, Lisbon, Portugal.

Article Synopsis
  • Eccentric contractions can significantly damage peripheral nerves, affecting various properties like structure and function within a short time frame (under 10 days).
  • A review of studies identified signs of nerve damage, such as reduced myelin sheath thickness and nerve conduction velocity, along with increased levels of certain proteins linked to nerve injury.
  • Findings suggest that higher velocity eccentric contractions exacerbate these effects, with notable differences observed between human and animal studies.

Article Synopsis
  • - This study explores the levels and geographical differences of contaminants found in house dust across Europe, identifying over 1200 anthropogenic compounds using advanced techniques like mass spectrometry and suspect screening.
  • - The research indicates that contaminant concentrations vary less than threefold within Europe, showing similarities with North American dust due to shared consumer products and materials.
  • - It highlights geographical patterns, revealing that certain contaminants increased from north to south (like PAHs and chlorinated paraffins), whereas others, like biocides, decreased; it also emphasizes a significant risk from older, restricted contaminants, like DEHP and PCBs, despite limited toxicity data available for newer compounds.

Identification of isoAsp7-Aβ as a major Aβ variant in Alzheimer's disease, dementia with Lewy bodies and vascular dementia.

Acta Neuropathol

December 2024

Paul Flechsig Institute - Centre of Neuropathology and Brain Research, University of Leipzig, Liebigstraße 19, 04103, Leipzig, Germany.

Article Synopsis
  • - The study investigated the role of various post-translational modifications of amyloid-β (Aβ) in different types of dementia, highlighting how specific Aβ variants could characterize distinct dementia forms, including Alzheimer's disease (AD) and other dementias like Lewy body dementia and vascular dementia.
  • - Researchers analyzed post-mortem brain tissues using immunohistochemical techniques and machine learning to quantify various Aβ modifications, finding that AD tissues had the highest levels of Aβ variants compared to other conditions.
  • - Notably, the isoAsp7-Aβ variant was found abundantly across all dementia types, while other modifications displayed varying distributions in plaque types and cerebral blood vessels, with some variants detected intraneuronally rather

Lancet Diabetes Endocrinol

January 2025

Department of Biomedical and Clinical Sciences, Linköping University, Linköping, Sweden; Steno Diabetes Center Copenhagen, Herlev, Denmark; Department of Clinical Medicine, University of Copenhagen, Copenhagen, Denmark.

Background: Advances in paediatric type 1 diabetes management and increased use of diabetes technology have led to improvements in glycaemia, reduced risk of severe hypoglycaemia, and improved quality of life. Since 1993, progressively lower HbA targets have been set. The aim of this study was to perform a longitudinal analysis of HbA, treatment regimens, and acute complications between 2013 and 2022 using data from eight national and one international paediatric diabetes registries.

Article Synopsis
  • Lewy body diseases, including Parkinson's disease, involve the spread of a protein called alpha-synuclein (αSyn) between neurons, making it important to study for treatment development.
  • The research focused on how neuronal activity affects the release of αSyn from dopaminergic neurons derived from human stem cells, comparing healthy neurons to those with a PD-related gene mutation.
  • Findings showed that increased neuronal activity boosts αSyn release, while decreased activity reduces it, highlighting the role of neuronal activity in the spread of Lewy pathology and suggesting potential new treatment strategies for neurodegenerative diseases.

Alzheimer's disease-specific transcriptomic and epigenomic changes in the tryptophan catabolic pathway.

Alzheimers Res Ther

November 2024

Department of Psychiatry and Neuropsychology, Faculty of Health, Medicine and Life Sciences (FHML), Mental Health and Neuroscience Research Institute (MHeNs) and European Graduate School of Neuroscience (EURON), Maastricht University, Maastricht, 6211 LK, the Netherlands.

Background: Neurodegenerative disorders, including Alzheimer's disease (AD), have been linked to alterations in tryptophan (TRP) metabolism. However, no studies to date have systematically explored changes in the TRP pathway at both transcriptional and epigenetic levels. This study aimed to investigate transcriptomic, DNA methylomic (5mC) and hydroxymethylomic (5hmC) changes within genes involved in the TRP and nicotinamide adenine dinucleotide (NAD) pathways in AD, using three independent cohorts.

Immune digital twins for complex human pathologies: applications, limitations, and challenges.

NPJ Syst Biol Appl

November 2024

Biocomplexity Institute and Department of Intelligent Systems Engineering, Indiana University, Bloomington, Indiana, 47408, USA.

Digital twins represent a key technology for precision health. Medical digital twins consist of computational models that represent the health state of individual patients over time, enabling optimal therapeutics and forecasting patient prognosis. Many health conditions involve the immune system, so it is crucial to include its key features when designing medical digital twins.

High-affinity ELR+ chemokine ligands show G protein bias over β-arrestin recruitment and receptor internalization in CXCR1 signaling.

J Biol Chem

November 2024

KU Leuven, Department of Microbiology, Immunology and Transplantation, Rega Institute for Medical Research, Molecular Structural and Translational Virology Research Group, Leuven, Belgium. Electronic address:

The human CXC chemokine receptor 1 (CXCR1), a G protein-coupled receptor (GPCR), plays significant roles in inflammatory diseases and cancer. While CXCL8 is a well-established high-affinity ligand for CXCR1, there is no consensus regarding the binding ability of the other ELR+ chemokines (CXCL1-3 and CXCL5-8). Since research has predominantly focused on CXCL8-mediated CXCR1 signaling, insight into potential signaling bias induced by different CXCR1 ligands is lacking.

Sleep medicine and internal medicine share a global and transdisciplinary vision of human physiology and illnesses, with an approach guided by the complaint and semiology. In France, approximately 13 to 18 million individuals suffer from a sleep disorder: these disorders therefore represent a public health problem. Their comorbidities with systemic autoimmune diseases are frequent.

Objective: Neuronal cell death and neuroinflammation are characteristic features of epilepsy, but it remains unclear whether neuronal cell death as such is causative for the development of epileptic seizures. To test this hypothesis, we established a novel mouse line permitting inducible ablation of pyramidal neurons by inserting simian diphtheria toxin (DT) receptor (DTR) cDNA into the Ccl17 locus. The chemokine CCL17 is expressed in pyramidal CA1 neurons in adult mice controlling microglial quiescence.

Cancer Epidemiol

November 2024

Ageing, Cancer, and Disparities Research Unit, Department of Precision Health, Luxembourg Institute of Health, 1A-B, rue Thomas Edison, Strassen 1445, Luxembourg. Electronic address:

Background: The global population aged 80 years or older is expected to triple by 2050, leading to an increased cancer burden in the oldest population. This study describes the estimated cancer incidence and mortality in 2022 and projections for 2050 in the oldest old, analyzed globally and by world regions and World Bank income levels, for all sexes combined, as well as separately for males and females.

Methods: Using GLOBOCAN 2022 estimates, we reported the estimated number of new cancer cases (excluding non-melanoma skin cancers), deaths, and truncated age-standardized incidence (ASIR) and mortality rates (ASMR) (per 100,000 individuals aged 80 years or older).

Allergen-specific immunotherapy (AIT) induces immune tolerance, showing the highest success rate (>95%) for insect venom while a much lower chance for pollen allergy. However, the molecular switches leading to successful durable tolerance restoration remain elusive. The primary outcome of this observational study is the comprehensive immunological cellular characterization during the AIT initiation phase, whereas the secondary outcomes are the serological and Th2-cell-type-specific transcriptomic analyses.
