α‐Synuclein strain homogeneity in multiple system atrophy subtypes

Brain Pathology, EarlyView.
Two different subtypes of multiple system atrophy are recognized: MSA‐C and MSA‐P. In this manuscript, Lau et al. investigate whether MSA‐C and MSA‐P are caused by different strains of α‐synuclein aggregates. By performing conformational fingerprinting experiments as well as in vitro and in vivo seeding assays, their findings suggest that both MSA‐C ...

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Molecular dynamics simulations elucidate the misfolding mechanisms of secretion‐defective pancreatic lipase variants

The FEBS Journal, EarlyView.
Misfolding mutations in pancreatic lipase have been identified as potential contributors of chronic pancreatitis, an inflammatory disease of the human pancreas. Here, we describe the effect of these misfolding mutations on pancreatic lipase structure using molecular dynamics simulations and structural modeling.

Combating ageing beyond the cell: Emerging roles of extracellular proteostasis

The FEBS Journal, EarlyView.
Ageing challenges the body's ability to maintain a stable and functional proteome, leading to protein damage and aggregation both inside and outside cells. This review focuses on the less well understood mechanisms of extracellular protein quality control and how they become disrupted in ageing, particularly in neurodegenerative diseases.

Seasonal variation in preen gland secretions of Tristram's Storm Petrel (Hydrobates tristrami)

Ibis, EarlyView.
Preen gland secretions are known to vary depending on sex, season and species and are thought to play essential roles in avian life history. However, their chemical composition and functions remain largely unclear in Procellariiform seabirds with well‐developed olfactory senses. Storm petrels, known for their distinctive body odour, may use preen gland

The Role of the Simulation in Supporting Newly Graduated Nurses in Their First 5 Months of Working Transition: Findings From a Mixed‐Method Study

Journal of Clinical Nursing, EarlyView.
ABSTRACT Aims To understand the role of simulation in ensuring the development of the competencies expected by newly graduated register nurses (NGRNs) from the work initiation up to 5 months of transition. Methods Mixed‐method study design. A longitudinal phase employing the Nurse Competence Scale (NCS, from 0 to 100, excellent) to assess the perceived

Bone Grafts: Everything You Need to Know

Journal of Periodontal Research, EarlyView.
This review classifies bone grafts (autograft, allograft, xenograft, synthetic) by source and osteogenic/inductive/conductive potential, linking material properties and mechanisms to clinical indications in periodontal and dental regeneration. Key challenges—limited osteoinduction, poor vascularisation, unbalanced resorption, handling difficulties, and

Novel murine closed‐loop auditory stimulation paradigm elicits macrostructural sleep benefits in neurodegeneration

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Boosting slow‐wave activity (SWA) by modulating slow waves through closed‐loop auditory stimulation (CLAS) might provide a powerful non‐pharmacological tool to investigate the link between sleep and neurodegeneration. Here, we established mouse CLAS (mCLAS)‐mediated SWA enhancement and explored its effects on sleep deficits in neurodegeneration,

Tick‐borne diseases in subtropical dairy farming: The role of calf rearing strategies in antibody and antigen prevalence Enfermedades Transmitidas por Garrapatas en la Ganadería Lechera subtropical: El Papel de las Estrategias de Crianza de Terneros en la Prevalencia de Anticuerpos y Antígenos

Medical and Veterinary Entomology, EarlyView.
Tropical farmers try to adapt calf‐rearing systems to temperate dairy industry standards. Calves in tick‐infested areas develop stronger immunity to TBD under controlled exposure to ticks. Early tick exposure promotes sustainable management, balancing tick infestation and developing TBD immunity.
