Background: The present study investigated the antioxidant, antimicrobial, and partial enzymatic properties of 52 thermophilic cyanobacteria isolates .
Materials And Methods: The DPPH scavenging method was applied to test the antioxidant potential of isolates' methanol extracts. Agar block diffusion and agar well diffusion methods were used to evaluate the antimicrobial activity and measured in milimeters.

A key issue in photoelectrochemical applications is the modification of the behavior of photogenerated charge barriers. An effective strategy to improve the photoelectrochemical performance of semiconductor materials is to use the facet effect to promote spatial charge separation. In this work, three different morphologies of lead chromate (PbCrO) crystals are prepared by a simple hydrothermal method that used ammonium fluoride as the structure-directing agents.

Understanding the impact of oxidative modification on protein structure and functions is essential for developing therapeutic strategies to combat macromolecular damage and cell death. However, selectively inducing oxidative modifications in proteins under physiological conditions remains challenging. Herein we demonstrate that [VO{(OCH)CCHOH}] (V-OH) hybrid metal-oxo cluster can be used for selective protein oxidative cleavage and modifications.

The lack of effective protection against UVB radiation, that severely disrupts the metabolism of keratinocytes, underlines the search for bioactive compounds that would provide effective protection without causing side effects. Therefore, the aim of the study has been to assess the effect of two compounds, that are different in terms of structure and properties: 3-O-ethyl ascorbic acid-EAA (a stable derivative of vitamin C) and cannabigerol-CBG, used separately or concurrently, on the metabolism of keratinocytes previously exposed to UVB. The obtained results indicate diverse, yet mutually reinforcing localization of the tested compounds, both within the membrane structures and cytosol.
