Mechanical Activation of Piezo1 Drives Osteoarthritis Through Kdm5c‐Mediated Epigenetic Silencing

Advanced Science, EarlyView.
Excessive mechanical stress activates Piezo1, triggering Ca2+‐dependent cytoskeletal forces that deform the nucleus and reduce H3K4me3. Kdm5c demethylates H3K4me3 at Col2a1 and Runx3 promoters. Kdm5c knockout rescues degradation. Repurposed telmisartan directly inhibits Kdm5c, blocking this axis and showing disease‐modifying efficacy in mouse OA models

The Role of Actual and Purported Origin in e‐Commerce Wine Pricing: Evidence From Italian and French Names on Labels

Agribusiness, EarlyView.
ABSTRACT The origin of a product, if associated with good quality, can contribute to building a positive collective reputation, leading to a potential price premium. However, it is conceivable that a producer markets a product by evoking symbols, images, words, and values typical of places other than where it was designed or produced, creating a ...

Finite Element Analysis of Vibration and Noise of Scraper Conveyor [PDF]

Proceedings of the 2015 International Conference on Industrial Technology and Management Science, 2015
The noise pollution produced by the scraper conveyor affects the working environment seriously. Based on a certain type of the scraper conveyor transmission system as a research object, using the finite element analysis software ANSYS for modal analysis, the results suggested that the natural frequencies of scraper and chute were the same in the 15 th ...
