Quercetin and Cardiovascular Health: An Evidence‐Based Review of Risk Factors and Treatments

Food Science &Nutrition, Volume 14, Issue 11, November 2026.
Quercetin is a naturally occurring polyphenolic phytochemical distributed in fruits and vegetables. Quercetin, as a flavonoid, showed significant antioxidant capabilities and potential therapeutic effects on CVD risk factors. Quercetin reduces cardiac hypertrophy and apoptosis in cardiomyocytes by modulating critical signaling pathways.

Potential role of NADPH-oxidase in early steps of lead-induced oxidative burst in Vicia faba roots [PDF]

, 2008
The mechanism of oxidative burst induced by lead in Vicia faba excised roots was investigated by luminol-dependent chemiluminescence. Results showed that lead triggered a rapid and dose-dependent increase in chemiluminescence production.

Iodized Garlic Extract Regulates Stress Responses in Epidermal Keratinocytes via the Transcription Factor Nrf2

Journal of Cosmetic Dermatology, Volume 25, Issue 11, November 2026.
ABSTRACT Objective Garlic exerts protective effects against skin stress, including oxidative damage and trauma. Iodized garlic extract (IGEx) is a cosmetic ingredient developed through iodination of garlic odor components to achieve odor reduction. Although IGEx is expected to exhibit skin stress protection properties similar to garlic, the molecular ...

Ultra‐Weak Photon Emission as a By‐Product of Mitochondrial Oxidative Metabolism: Mechanisms, Limits, and Implications

Nanophotonics, Volume 15, Issue 20, 27 October 2026.
Mitochondrial oxidative metabolism generates ROS. Downstream chemiexcitation triplet carbonyls, singlet oxygen; produces ultra‐weak photon emission (UPE). Energetic bounds restrict well‐coupled respiration to extremely weak, red/NIR‐biased emission. Stronger visible UPE indicates elevated oxidative flux, linking measured photon counts to redox state ...

Cofactor engineering in cyanobacteria to overcome imbalance between NADPH and NADH: A mini review

, 2017
Cyanobacteria can produce useful renewable fuels and high-value chemicals using sunlight and atmospheric carbon dioxide by photosynthesis. Genetic manipulation has increased the variety of chemicals that cyanobacteria can produce. However, their uniquely

Incubation of protonated NADH or NADPH with ortho-aminobenzaldehyde generates a novel fluorescent nicotinamide dihydroquinazoline condensate

, 2023
Incubation of reduced nicotinamide adenine dinucleotide (NADH) but not oxidized NAD+ with ortho-aminobenzaldehyde (oABA) generated an uncharacterized chromophore with an absorption peak characteristic of a dihydroquinazoline condensate.

Spray‐Dried Engineered Escherichia coli Whole‐Cell Biocatalysts Enable Cell Recycling and In Vivo α‐Ketoglutarate and NADPH Regeneration for Efficient Codeine Manufacture

Biotechnology and Bioengineering, Volume 123, Issue 10, Page 2629-2642, October 2026.
ABSTRACT A recombinant whole‐cell biocatalytic approach provides several advantages over isolated enzymes, such as improved enzyme stability, in vivo cofactor regeneration, and the facilitation of cascade reactions within a single cell. Whole‐cell biocatalysis has gained attention in medicinal opioid production, due to its technical and economic ...

Enzymatic Electrosynthesis for Sustainable CO2 Conversion: Advancing Circular Carbon Economy

Carbon Energy, Volume 8, Issue 10, October 2026.
Enzymatic electrosynthesis (EES) offers molecular precision in synthesizing value‐added products from CO2. We highlight its distinct edge over alternative enzyme‐hybrid systems and analyze electron transfer pathways. Key strategies to overcome electron transfer bottlenecks and expand product diversity are addressed, and also data‐driven approaches for ...
