Novel Monoclonal Antibody Detects Small Aβ Oligomers More Sensitively Than Lecanemab in Alzheimer's Disease CSF, Serum and Culture Media

Annals of Neurology, EarlyView.
Objective Aqueously diffusible oligomers of the amyloid β‐protein (oAβ) are neurotoxic and play a role in neuronal dysfunction in Alzheimer's disease (AD). Accurate quantification of oAβ in brains and biofluids could be valuable for understanding and monitoring AD.

Enhancement of molecular weight reduction of natural rubber in triphasic CO2/toluene/H2O systems with hydrogen peroxide for preparation of biobased polyurethanes

Green Processing and Synthesis, 2019
Molecular weight reduction of natural rubber (NR) with hydrogen peroxide (H2O2) oxidizing agent is limited in biphasic water-toluene systems that is attributed to mass transfer.

Revisiting the microtubule based quantum models of mind: tubulin bound GTP cannot pump microtubule coherence or provide energy for alpha <-> beta computation in stable microtubules [PDF]

, 2003
The current paper investigates the biological models of stable brain microtubules as quantum or classical computers whose function is based on electron hopping associated with kinking of the tubulin dimer. Hameroff (1998a, 1998b, 2003a, 2003b), Tuszynski

EFFECT OF OZONATION PROCESS ON PHYSICOCHEMICAL AND RHEOLOGICAL PROPERTIES OF κ-CARRAGEENAN

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2017
κ-Carrageenan is a sulfated galactan extracted from red algae (Rhodophyceae) which has many functions. However, nonfood applications of κ-carrageenan have been limited by its superior gelling and viscosity properties.

The 68,000-Dalton Neurofilament-Associated Polypeptide is a Component of Nonneuronal Cells and of Skeletal Myofibrils [PDF]

, 1980
Purified preparations of 10-nm neurofilaments from rat spinal cord and bovine or porcine brain contain a predominant 68,000-dalton polypeptide. This polypeptide is also a major component of the neurofilaments that copurify with brain tubulin isolated by ...
