Misdiagnosis of hereditary amyloidosis as AL (Primary) amyloidosis [PDF]

open access: yes, 2002
Background: Hereditary, autosomal dominant amyloidosis, caused by mutations in the genes encoding transthyretin, fibrinogen A -chain, lysozyme, or apolipoprotein A-I, is thought to be extremely rare and is not routinely included in the differential ...

Analysis of a Novel Time‐Continuous Dimer Growth Model Describing One Possible Cause of Alzheimer's Disease and a Time‐Discretization for Its Numerical Simulation

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Because oligomers of the amyloid‐β$$ \beta $$ (Aβ$$ A\beta $$) protein can possibly be regarded as one main cause for progressive development of Alzheimer's disease, different mathematical models for its emergence have been proposed by different scientific groups.

Imaging patterns and genetic associations of brain atrophy across distinct symptom stages in Parkinson's disease

open access: yesNeuroprotection, EarlyView.
Early disease stages showed limited cortical atrophy and enrichment of synaptic and calcium signaling pathways, whereas advanced stages demonstrated widespread cortical degeneration associated with immune activation and extracellular matrix remodeling.

Taxonomy of a novel and a new geographical record of Nigropunctata species (Pallidoperidiaceae) on Bambusa vulgaris from northern Thailand

open access: yesNordic Journal of Botany, EarlyView.
Nigropunctata is an understudied genus of bambusicolous fungi, and its diversity in Thailand remains poorly known. This study aimed to investigate species of Nigropunctata associated with bamboo in Thailand using morphological observations along with multi‐locus phylogenetic analyses of the internal transcribed spacer (ITS), large subunit (LSU), RNA ...

Amanita theophili sp. nov. (Amanitaceae) from central Mexico

open access: yesNordic Journal of Botany, EarlyView.
Amanita theophili sp. nov., a member of Amanita sect. Amidella (Amanitaceae), is described from temperate pine‐oak forests in Morelos, central Mexico. Morphological features and phylogenetic analyses based on ITS and 28S rDNA sequences confirm its distinct taxonomic status. The new species is morphologically similar to A. peckiana and A.

The cytoxocity of amyloid fibrils

open access: yes, 2011
Amyloid assemblies consist of an organised cross ~-sheet structure and can be formed by many proteins or peptides regardless of peptide sequence. Amyloid has been utilised by many species for a variety of functions, however, inappropriate amyloid ...

Impact of Stabilizing Osmolytes on the Conformational Dynamics of Human and Rat Islet Amyloid Polypeptides

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The aggregation of human islet amyloid polypeptide (hIAPP) into cytotoxic oligomers and amyloid fibrils is a hallmark of type 2 diabetes mellitus (T2DM), leading to pancreatic β‐cell dysfunction. In contrast, rat IAPP (rIAPP) is largely non‐amyloidogenic. Osmolytes such as glucose, glycerol, and sorbitol are known to stabilize globular protein
