Norpsilocin: freebase and fumarate salt

mycolabadmin

Researchers determined the crystal structures of norpsilocin, a naturally occurring compound found in magic mushrooms that is chemically similar to psilocin. This work is important because norpsilocin appears to be as potent as psilocin at serotonin receptors and may contribute to the therapeutic effects of magic mushroom extracts. By obtaining pure crystalline forms and understanding the compound’s structure, scientists can better study its properties and potential medical applications for treating conditions like depression and anxiety.

Fully Bio-Based Hybrid Composites Made of Wood, Fungal Mycelium and Cellulose Nanofibrils

mycolabadmin

Scientists developed a new type of eco-friendly composite material by combining wood particles, fungal mycelium, and cellulose fibers without using toxic formaldehyde glues. The fungus naturally bonds to the wood surface, and when combined with plant-based cellulose fibers, creates a strong, water-resistant material suitable for furniture and packaging. This fully natural composite requires much less cellulose fiber than previous methods, making it more practical for commercial production.

The Molecular Mechanism of Polysaccharides from Polygonatum cyrtonema Hua in Improving Hyperuricemia by Regulating Key Targets of Uric Acid Metabolism in Mice

mycolabadmin

This research demonstrates that a traditional Chinese medicinal plant called Polygonatum cyrtonema contains beneficial polysaccharides that can help lower high uric acid levels in the blood, which is a major cause of gout and kidney disease. The study found that these polysaccharides work by reducing the enzyme that produces uric acid and helping the kidneys excrete more of it, while also reducing inflammation. Importantly, this natural treatment protected kidney tissue better than the standard pharmaceutical drug allopurinol, suggesting it could be a safer long-term option for managing high uric acid levels.

Effect of soluble dietary fiber from corn bran on pasting, retrogradation, and digestion characteristics of corn starch

mycolabadmin

Researchers found that adding a special fiber derived from corn bran to corn starch significantly improves its properties for food production. The fiber helps prevent the starch from hardening over time, reduces how quickly the body digests it (important for controlling blood sugar), and improves texture and water retention. This discovery could help create healthier starch-based foods and better products for people with swallowing difficulties.

Ultrasound-Assisted Determination of Selenium in Organic Rice Using Deep Eutectic Solvents Coupled with Inductively Coupled Plasma Mass Spectrometry

mycolabadmin

This study developed environmentally friendly solvents called deep eutectic solvents (DESs) to detect selenium in rice without using toxic chemicals. Researchers optimized four different DES formulations and used ultrasonic waves to extract selenium from rice samples. The new green chemistry approach achieved comparable or better results than traditional harsh acid digestion methods while being safer for the environment.
