Fungal formation of selenium and tellurium nanoparticles [PDF]

Applied Microbiology and Biotechnology, 2019
The fungi Aureobasidium pullulans, Mortierella humilis, Trichoderma harzianum and Phoma glomerata were used to investigate the formation of selenium- and tellurium-containing nanoparticles during growth on selenium- and tellurium-containing media. Most organisms were able to grow on both selenium- and tellurium-containing media at concentrations of 1 ...

Selenium Nanoparticles Selectively Target KRAS G13D to Inhibit Colorectal Cancer. [PDF]

Adv Sci (Weinh)
The mechanisms of SeNPs therapy in cancer treatment, encompass three parallel actions: (1) seleno‐amino acids, key metabolites, upregulate GPX2 expression, thereby inhibiting tumor metastasis via the GPX2‐HIF1α‐VEGF signaling pathway; (2) selenite (SeO32−), an inorganic metabolite, forms hydrogen bonds with amino acid residues 13–17 of the KRAS G13D ...

In situ Synthesis of Metal Selenide Nanoparticles by Selenium Nanoparticle Disproportionation [PDF]

, 2023
Amorphous Selenium Nanoparticles (α-SeNPs) exist in a metastable state of polymeric Se8 rings and Sen chains that break and reform by electron propagation. Here we show that this quality can underlie the formation of metal selenide nanoparticles (MSeNPs)

Antimycobacterial Effect of Selenium Nanoparticles on Mycobacterium tuberculosis [PDF]

Frontiers in Microbiology, 2020
Tuberculosis (TB) remains the leading cause of death from a single infection agent worldwide. In recent years, the occurrence of TB cases caused by drug-resistant strains has spread, and is expected to continue to grow. Therefore, the development of new alternative treatments to the use of antibiotics is highly important.

Enhancing the Activity of Carboxymethyl Cellulase Enzyme Using Highly Stable Selenium Nanoparticles Biosynthesized by Bacillus paralicheniformis Y4

Molecules, 2022
The inorganic selenium is absorbed and utilized inefficiently, and the range between toxicity and demand is narrow, so the application is strictly limited.

The Effects of Selenium Nanoparticles (SeNPs) on Ruminant

Proceedings of the Mongolian Academy of Sciences, 2020
This study examines the role of selenium and the effects of selenium nanoparticle-enriched food supplementation especially in ruminant animals. Selenium is an essential element that has multiple biological activities. Particularly it is important for many physiological processes, especially for the functions of reproductive and immune systems ...

SELENIUM IN NANOFORM: TOXICITY AND SAFETY

Байкальский медицинский журнал, 2022
The review is devoted to the toxicity and safety of nanosized forms of selenium. It is shown that in nature selenium exists mainly in the form of selenate (Se6+), selenite (Se4+), selenide (Se2–) and elemental selenium (Se0), while the latter is ...

Advances in selenium supplementation: From selenium-enriched yeast to potential selenium-enriched insects, and selenium nanoparticles

Animal Nutrition, 2023
Selenium (Se) is an essential micronutrient that plays an important role in animal and human development and physiological homoeostasis. This review surveys the role of Se in the environment, plants and animal bodies, and discusses data on Se biofortification with different sources of supplementation, from inorganic to organic forms, with special focus
