Biological evaluation and molecular modelling of didanosine derivatives [PDF]

, 2014
Five carbonate derivatives of 50-O-20,30-dideoxyinosine (DDI, 1) have been synthesized by combination with aliphatic alcohols, with their in vitro anti-HIV activity and cytotoxicity being evaluated afterward in human peripheral blood mononuclear cells ...

Photoprotective potential of gadusol against ultraviolet B radiation in melanocytes

Photochemistry and Photobiology, EarlyView.
Gadusol protects melanocytes from ultraviolet B (UVB)‐induced damage without cytotoxicity. Abstract The increasing incidence of skin cancer, including melanoma, combined with the need for ultraviolet (UV) filters that are safe for human health and marine ecosystems, is driving the search for new photoprotective agents.

The Major Soybean Allergen Gly m Bd 28K Induces Hypersensitivity Reactions in Mice Sensitized to Cow's Milk Proteins [PDF]

, 2016
Reactions to soy have been reported in a proportion of patients with IgE-mediated cow’s milk allergy (CMA). In this work, we analyzed if Gly m Bd 28K/P28, one of the major soybean allergens, is a cross-reactive allergen with cow milk proteins (CMP).

Exploring the Antimicrobial Potential of Vanadium‐Based MXenes for Biomedical Applications

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Vanadium‐based MXenes (V₂CTₓ and V₄C₃Tₓ) exhibit moderate antibacterial activity against E. coli and S. aureus, mainly through mechanical “nano‐knife” membrane disruption rather than ROS generation. These nanomaterials show good biocompatibility and highlight the importance of standardized experimental models for evaluating MXene antimicrobial ...

Flavoprotein monooxygenases for oxidative biocatalysis: recombinant expression in microbial hosts and applications [PDF]

, 2014
External flavoprotein monooxygenases comprise a group of flavin-dependent oxidoreductases that catalyze the insertion of one atom of molecular oxygen into an organic substrate and the second atom is reduced to water. These enzymes are involved in a great

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

Pest Management Science, Volume 82, Issue 6, Page 5184-5194, June 2026.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.
