Prototype of Data Collector from Textronic Sensors.

In the era of miniaturization of electronic equipment and the need to connect sensors with textile materials, including clothing, the processing of signals received from the implemented sensors becomes an important issue. Information obtained by measuring the electrical properties of the sensors must be sent, processed, and visualized. For this purpose, the authors of this article have developed a prototype of a data collector obtained from textronic sensors created on composite textile substrates.

Quercetin protects ARPE-19 cells against photic stress mediated by the products of rhodopsin photobleaching.

Although the primary biological function of retina photoreceptors is to absorb light and provide visual information, exposure to intense light could increase the risk of phototoxic reactions mediated by rhodopsin photobleaching products (RPBP) that might accumulate in photoreceptor outer segments (POS). Here we investigated whether quercetin can modify the phototoxic potential of RPBP under in vitro photic stress conditions. ARPE-19 cells or quercetin enriched cultures pre-loaded with rhodopsin-rich POS isolated from bovine retinas were irradiated with green light to photobleach rhodopsin, and subsequently with blue light.
