Prions And Prion Diseases

open access: yesAfrican Journal of Clinical and Experimental Microbiology, 2008
A prion is a small infectious particle, which resist inactivation by procedures that modify nucleic acids. Transmissible spongiform encephalopathies (TSEs also known as prion diseases) are a group of progressive conditions that affects the brain and nervous system of humans and animals and are transmitted by prions.

Redox environment modulates aggregation of ataxin‐3 in vitro — Implications for drug screening of cysteine‐rich proteins

open access: yesThe FEBS Journal, EarlyView.
Redox environment modulates in vitro aggregation of Ataxin‐3, the protein implicated in spinocerebellar ataxia type 3. Reducing conditions stabilize native monomers and prevent aggregation, whereas oxidative conditions promote the formation of non‐native conformers and disulfide‐linked oligomers within the Josephin domain (JD).

Proteostasis of organelles in aging and disease

open access: yesThe 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 ...

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

open access: yesJournal 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

Endogenous Viral Etiology of Prion Diseases [PDF]

open access: yes, 2009
Transmissible spongiform encephalopathies (TSEs), or prion diseases, are a group of incurable neurodegenerative disorders, including Kuru and Creutzfeldt-Jakob disease in humans, “mad cow” disease in cattle, and scrapie in sheep. This paper

Bone Grafts: Everything You Need to Know

open access: yesJournal 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

Strain-Specific Targeting and Destruction of Cells by Prions

open access: yesBiology
Prion diseases are caused by the disease-specific self-templating infectious conformation of the host-encoded prion protein, PrPSc. Prion strains are operationally defined as a heritable phenotype of disease under controlled conditions.

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

open access: yesJournal 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,

Characterisation and prion transmission study in mice with genetic reduction of sporadic Creutzfeldt-Jakob disease risk gene Stx6

open access: yesNeurobiology of Disease
Sporadic Creutzfeldt-Jakob disease (sCJD), the most common human prion disease, is thought to occur when the cellular prion protein (PrPC) spontaneously misfolds and assembles into prion fibrils, culminating in fatal neurodegeneration.
