Ebselen delays blood clot formation
Anti-oxidant ebselen delays microvascular thrombus formation in the rat cremaster muscle by inhibiting platelet P-selectin expression.
Relevant to oxidative stress research
We explored the effects of ebselen, a selenium compound known for its antioxidant properties, on blood clot formation in rats. Our study demonstrated that ebselen significantly delayed thrombus formation in microvessels.

In particular, animals treated with ebselen showed a marked delay in vessel occlusion compared to those treated with a control substance. In most cases, ebselen entirely prevented blood clot formation in arterioles.

This suggests that ebselen can be effective in reducing the risk of blood clots, particularly in situations characterized by oxidative stress.

Antioxidants may aid cardiovascular health
Effect of low dose antioxidant vitamin and trace element supplementation on the urinary concentrations of thromboxane and prostacyclin metabolites.
High relevance to cardiovascular research
We explored how low-dose antioxidant supplements affect urinary markers linked to blood clotting and cardiovascular health. In this randomized, double-blind, placebo-controlled study with 186 healthy volunteers, one group received supplements while the other received a placebo for two years.

Our findings show that participants who took the multi-antioxidants had significantly lower levels of a specific urinary marker associated with platelet activity. Notably, selenium was particularly linked to these results, suggesting it can help reduce clot formation, which might support heart health.

Selenium may reduce platelet function
Effects of sodium selenite on in vitro interactions between platelets and endothelial cells.
Moderate relevance to thrombosis research.
Our study explored how selenium influences the interaction between platelets and endothelial cells, especially regarding blood clot formation. We noticed that selenium supplementation increased the activity of protective enzymes in both platelets and endothelial cells.

Interestingly, we found that platelets showed reduced aggregation in the presence of selenium-rich endothelial cells. However, this effect was nullified when we used aspirin, indicating a complex relationship. Ultimately, while selenium shows promise, we did not find significant improvements in nitric oxide levels linked to clot prevention.

Significantly increased levels
Excellent selenium! After two months, my blood levels rose considerably. The tablets are small, thin, and easy to swallow. I highly recommend them.

Menstrual cycle restored
At the start of last year, my cycles stopped after recovering from a virus associated with childbirth. After taking a vitamin complex including selenium, my cycle surprisingly resumed. Initially, I didn’t link it to this medication, but I noticed how my blood thinned, resulting in a regular cycle. I haven’t taken it for a month, and now there's a delay again. I’ll see if it helps once more, although I feel the dosage might be a bit high.

Effective supplementation
Excellent! I take it on the recommendation of my gynaecologist-endocrinologist, and it has raised my selenium levels in the blood effectively.

Selenium-based therapy shows promise
Bionanoengineered 2D monoelemental selenene for piezothrombolysis.
High relevance in thrombolytic research
We explored a new approach to treat blood clots using piezoelectric selenene. This study introduced a unique design that combines selenene with platelet membranes, enhancing its ability to target thrombosis.

Under ultrasound, the selenene generates reactive oxygen species, effectively dissolving clots without the bleeding risks associated with traditional therapies.

In both lab and live animal tests, these selenium-based nanosheets demonstrated impressive results, outperforming a standard clinical drug. It's a promising step toward safer, more effective treatments for thrombosis.

Selenium polymer reduces blood clots
Multifunctional Nitroso--acetylpenicillamine-Incorporated Medical-Grade Polymer with Selenium Interface for Biomedical Applications.
High relevance in medical devices
We explored the effectiveness of a new polymer infused with selenium in tackling blood clots and infections associated with medical devices. This SNAP-Se-1 composite works by releasing nitric oxide (NO), a natural defender against both issues. We found that it remarkably reduced platelet adhesion by 85.5% while also displaying antibacterial properties. Importantly, this innovative approach minimizes the need for traditional antibiotic treatments. Overall, while we see promising results in lab settings, further research is needed to confirm these benefits in real-world applications.

Enhanced imaging for carotid thrombosis
High Contrast Detection of Carotid Neothrombus with Strong Near-Infrared Absorption Selenium Nanosphere Enhanced Photoacoustic Imaging.
High relevance for stroke diagnosis
We investigated how selenium-based nanomaterials boost photoacoustic imaging to identify carotid artery blood clots more effectively. By using a thrombosis model in mice, we found that these nanocomposites significantly enhanced imaging signals—up to 5 times greater—which helps diagnose the extent of carotid atherosclerosis.

This research suggests that selenium/polypyrrole nanoparticles may be a promising tool for improving the detection and diagnosis of carotid thrombosis, potentially leading to better stroke prevention strategies.
