ANTIOXIDANT ENZYME ACTIVITY IN RENAL ISCHEMIA

Renal ischemia is accompanied by severe metabolic disturbances, one of the key components of which is the development of oxidative stress. Oxygen deficiency and impaired microcirculation lead to increased generation of reactive oxygen species, which damages cell membranes, proteins, and DNA.

Understanding Active Photoprotection: DNA-Repair Enzymes and Antioxidants

Life
The detrimental effects of ultraviolet radiation (UVR) on human skin are well-documented, encompassing DNA damage, oxidative stress, and an increased risk of carcinogenesis. Conventional photoprotective measures predominantly rely on filters, which scatter or absorb UV radiation, yet fail to address the cellular damage incurred post-exposure.

Molecular Editing Reveals a Bilobalide Chemotype that Attenuates Prolyl Endopeptidase (PREP)‐Linked Neuroinflammation

Advanced Science, EarlyView.
Molecular editing of bilobalide uncovers BB56, a PREP‐engaging chemotype with enhanced anti‐inflammatory activity in microglia. Integrated CETSA‐MS, SAR, and pathway analyses link BB56 to attenuation of p38 MAPK/NF‐κB and NLRP3‐associated inflammatory signaling, highlighting bilobalide editing as a strategy for developing neuroinflammation‐modulating ...

Elemental composition and antioxidant enzyme activity of roots and shoots of wheat grown in manganese spiked Montado alentejano soil

, 2018
Soils occupied by the Montado system are acid and susceptible to winter waterlogging, promoting soil Mn bioavailability and its plant toxicity, that impairs crop yields. Plant Mg/Mn ratios >20 and increased plant antioxidant enzyme activity may reduce Mn
