Transient receptor potential Ankyrin-1 (TRPA1) agonists suppress myelination and induce demyelination in organotypic cortical slices.

Oligodendrocytes are highly specialized glial cells characterized by their production of multilayer myelin sheaths that wrap axons to speed up action potential propagation. It is due to their specific role in supporting axons that impairment of myelin structure and function leads to debilitating symptoms in a wide range of degenerative diseases, including Multiple Sclerosis and Leukodystrophies. It is known that myelin damage can be receptor-mediated and recently oligodendrocytes have been shown to express Ca -permeable Transient Receptor Potential Ankyrin-1 (TRPA1) channels, whose activation can result in myelin damage in ischemia.

The Use of Cell Elastography to Study the Biomechanical Properties of Bacillus subtilis.

The cytometric, elastic, and adhesion properties of Bacillus subtilis at different terms of culturing were studied. The cytometric parameters of bacterial cells increased by day 6 in culture and decreased at later terms. Analysis of membrane rigidity showed that parameters describing bacterial elastic properties underwent waveform changes: the decrease in bacterial elasticity (from day 1 to 6) was followed by its increase on day 12 in culture.

Self-diffusion in a hyaluronic acid-albumin-water system as studied by NMR.

Hyaluronic acid (HA) is an anionic biopolymer that is present in many tissues and can be involved in cancerous neoformations. HA can form complexes with proteins (particularly, serum albumin) in the body. However, HA structures and processes involving HA have not been extensively studied by NMR because the molecule's rigid structure makes these studies problematic.
