A Hybrid Nanosystem for Prostate Cancer Therapy: Codelivery of Enzalutamide and Curcumin via Selenium‐Embedded Mesoporous Silica and Chitosan Nanoparticles

ChemistryOpen, Volume 15, Issue 3, March 2026.
Herein, solvent extraction was selected for cetyltrimethylammonium bromide removal and the development of optimized Se‐embedded mesoporous silica nanoparticles, which were loaded with enzalutamide. Additionally, to improve the anticancer activity of Se@MSNPs‐Enz and curcumin bioavailability, curcumin‐loaded chitosan nanoparticles were prepared. This pH‐

From Light‐Driven to Dark Synthesis: Streamlining Perfluoroalkyl Selenide Ether Formation

European Journal of Organic Chemistry, Volume 29, Issue 5, 7 February 2026.
Two orthogonal and user‐friendly protocols enable the efficient construction of (Se/S)RF bonds from simple dichalcogenides and perfluoroalkyl iodides. Visible‐light irradiation at 395 nm promotes seleno‐ and thioether formation, while a dark KOH/MeCN variant delivers selenoethers in minutes. Both approaches operate under mild, metal‐ and photocatalyst‐

Structural basis for the binding of tryptophan-based motifs by δ-COP. [PDF]

, 2015
Coatomer consists of two subcomplexes: the membrane-targeting, ADP ribosylation factor 1 (Arf1):GTP-binding βγδζ-COP F-subcomplex, which is related to the adaptor protein (AP) clathrin adaptors, and the cargo-binding αβ'ε-COP B-subcomplex. We present the

Reprogramming M2b Macrophages via GPX1 Activation by Selenium Nanoparticles Attenuates Lupus Nephritis

Advanced Science, Volume 13, Issue 12, 27 February 2026.
SeZM NPs selectively target M2b macrophages through mannose–MRC1 (CD206) recognition, enhance GPX1 biosynthesis, and suppress mitochondrial ROS generation, oxidative stress, and JAK–STAT signaling. This dual regulation reduces pro‐inflammatory cytokine release, limits immune cell infiltration and fibrosis, and preserves renal function, providing a ...

Selenium and selenium species in feeds and muscle tissue of Atlantic salmon [PDF]

, 2018
Selenium (Se) is an essential element for animals, including fish. Due to changes in feed composition for Atlantic salmon (Salmo salar), it may be necessary to supplement feeds with Se.

Determination of selenium speciation in the muscle, kidney, and liver from different animals treated with different selenium supplements by HPLC‐ICP‐MS

Animal Research and One Health, Volume 4, Issue 1, Page 67-81, February 2026.
Dietary selenium (Se) deficiency is recognized as a global problem, and exogenous Se supplementation can effectively enrich its levels in animal bodies. Offal tissues are equally important as meat in Se enrichment. Varying properties among Se species require information beyond total Se concentration to fully evaluate health risk/benefits.

Toxicity of Aqueous L-Selenomethionine and Tert-Butyl Hydroperoxide Exposure to Zebrafish (Danio rerio) Embryos Following Tert-Butyl Hydroquinone Treatment

Toxics, 2019
Aqueous L-selenomethionine (SeMet) embryo exposures represent a rapid and simplified method for investigating the embryotoxic effects of SeMet. Using zebrafish (Danio rerio) as a model organism, the objective of the present study was to characterize the ...

Understanding the Redox Biology of Selenium in the Search of Targeted Cancer Therapies

Antioxidants, 2020
Selenium (Se) is an essential trace nutrient required for optimal human health. It has long been suggested that selenium has anti-cancer properties. However, clinical trials have shown inconclusive results on the potential of Se to prevent cancer.
