Selenium nanofibers enhance wound healingSelenium-containing polyurethane nanofibers with MnO nanoparticles and gelsevirine promote diabetic wound healing by modulation of ROS and inflammation.
High relevance for diabetic wound healing
We explored how selenium-containing polyurethane nanofibers can aid in diabetic wound healing. The study developed unique nanofibers designed to tackle harmful reactive oxygen species (ROS) and inflammation, both of which impede recovery.
These nanofibers demonstrated excellent ability to reduce ROS levels, leading to remarkable healing results—showing up to 92% improvement within 14 days. Additionally, they maintained high cell viability, indicating safety. Overall, this innovative approach could significantly enhance treatment for diabetic wounds.

Effective hydrogel for diabetic woundsInfluence of chitosan and hydroxyethyl cellulose modifications towards the design of cross-linked double networks hydrogel for diabetic wound healing.
Highly relevant to wound healing
We investigated the effectiveness of a new hydrogel designed for diabetic wound healing, made from oxidized hydroxyethyl cellulose (OHEC) and chitosan with selenium nanoparticles.
This hydrogel demonstrated impressive properties, including superior antioxidant and antibacterial abilities, which contribute to faster wound healing.
Our findings showed a remarkable 100% wound closure in laboratory tests within 12 hours and almost complete healing in animal models within 14 days.
Overall, this study highlights the hydrogel's multifunctional benefits, making it a promising option for treating chronic and infected wounds.

Selenium's role in diabetes treatmentNanometerizing Taxifolin Into Selenized Liposomes to Ameliorate Its Hypoglycemic Effect by Optimizing Drug Release and Bioavailability.
Limited understanding of selenium's effect
We sought to understand how selenium, when combined with taxifolin, might improve treatment options for diabetes mellitus. The focus was on creating selenized liposomes, or Tax-Se@LPs, that would enhance the delivery and effectiveness of taxifolin, a natural compound known for its potential health benefits.
Through a specialized manufacturing technique, we developed these nanometric liposomes and assessed their performance in preclinical settings. Our findings indicated that Tax-Se@LPs not only improved the absorption of taxifolin in the digestive system but also significantly reduced blood glucose levels in diabetic models. With a relative bioavailability of 216.65%, the selenized formulation demonstrated a more prolonged effect compared to other delivery methods.
Despite these promising results, our study did not isolate the effectiveness of selenium on its own. The benefits observed were largely attributed to the advanced delivery system rather than the selenium content alone. Therefore, while increased bioavailability and hypoglycemic effects are evident from using Tax-Se@LPs, the specific role that selenium plays in these outcomes needs further exploration for a clearer understanding.

Selenium's Role in Diabetes ControlMolecular Observations on the Regulation of hIAPP Aggregation Process and Enhancement of Autophagy by the Short Peptide LPFYPN and Its Modified Peptides of Coix Seed Prolamins.
Assessment of peptide efficacy
We investigated how selenium-modified peptides affect the aggregation of the human islet amyloid polypeptide (hIAPP), which is known to have a role in diabetes. Our study focused on the active peptide derived from coix seed prolamins called LPFYPN (LP6) and its modified versions.
Through our experiments, we observed that both LP6 and its modified peptides, particularly the selenium-enhanced version, significantly inhibited the harmful aggregation of hIAPP. This aggregation is linked to the cytotoxic effects that can worsen diabetes conditions.
The findings showed that the selenium-modified peptide not only reduced these harmful aggregates but also helped to boost the body's autophagy processes—essentially improving how cells eliminate these damaging proteins. By doing so, it reduced cell toxicity and promoted healthier cell function.
Overall, our results suggest that selenium holds potential in developing new dietary approaches to manage type 2 diabetes and possibly other amyloid-related diseases. This could mean that including selenium-rich ingredients in our diet may provide valuable health benefits in tackling diabetes health challenges.

Antidiabetic effects of seleniumPhysicochemical properties, structural characterization, and antidiabetic activity of selenylated low molecular weight apple pectin in HFD/STZ-induced type 2 diabetic mice.
High relevance to diabetes treatment
We investigated the impact of a novel selenylated low molecular weight apple pectin on diabetes management. The study focused on mice induced with type 2 diabetes through a high-fat diet and streptozotocin treatment.
Our findings revealed that this modified pectin significantly improved several diabetic symptoms. It reduced weight loss, lower blood sugar levels, and oxidative stress, while also protecting organs like the liver and kidneys.
Additionally, we observed enhanced glucose tolerance and improvements in lipid metabolism and insulin sensitivity among the mice receiving the treatment. The selenylated apple pectin not only had a notable effect on glucose metabolism but also appeared to offer protective benefits against inflammation and tissue damage.
