An Open Access Data Set Highlighting Aggregation of Dyes on Metal Oxides

Data, 2020
The adsorption of a dye to a metal oxide surface such as TiO2, NiO and ZnO leads to deprotonation and often undesirable aggregation of dye molecules, which in turn impacts the photophysical properties of the dye.

Cholesterol determines the cytosolic entry and seeded aggregation of tau

Cell Reports, 2022
Summary: Assemblies of tau can transit between neurons, seeding aggregation in a prion-like manner. To accomplish this, tau must cross cell-limiting membranes, a process that is poorly understood. Here, we establish assays for the study of tau entry into

Local aggregation in a dynamic setting [PDF]

, 1990
Although it is not possible, in general, to give a macro description of a micro model over the entire state space of the micro model, it is possible to aggregate exactly over a subspace.

A Cell- and Tissue-Specific Weakness of the Protein Homeostasis System Underlies Brain Vulnerability to Protein Aggregation

iScience, 2020
Summary: The phenomenon of protein misfolding and aggregation is associated with a wide range of neurodegenerative conditions that cause progressive loss of function in specific regions of the human brain.

Global analysis of protein aggregation in yeast during physiological conditions and arsenite stress

Biology Open, 2014
Protein aggregation is a widespread phenomenon in cells and associated with pathological conditions. Yet, little is known about the rules that govern protein aggregation in living cells. In this study, we biochemically isolated aggregation-prone proteins

Protein aggregation in E. coli : short term and long term effects of nutrient density. [PDF]

PLoS ONE, 2014
During exponential growth some cells of E. coli undergo senescence mediated by asymmetric segregation of damaged components, particularly protein aggregates. We showed previously that functional cell division asymmetry in E.

A Missing Origin of the Tau Protein Aggregation Pathway Triggered by Thermal and Biological Forces

Journal of Integrative Neuroscience, 2023
Fluctuations in mechanical force vectors within living cells can substantially influence the behavior and functions of proteins. Tau protein can spontaneously be raptured and entangled in refolding under picoNewton compressive forces that are ...

Exercise Capacity, Physical Activity, Fatigue, and Neurocognitive Function in Adult Survivors of Childhood Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adult survivors of childhood acute lymphoblastic leukemia (ALL) are at risk of reduced exercise capacity, decreased physical activity levels, persistent fatigue, and neurocognitive deficits. The aim was to investigate exercise capacity and physical activity levels of adult survivors of childhood ALL and their associations with ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
