Biogenic Synthesis, Structural Characterization, and Biological Evaluation of Nanoparticles Derived fromEthanolic Extract.
2026
Nanomaterials (Basel, Switzerland)
Ivanova A, Todorova M, Petrov D, Gledacheva V, Stefanova I +11 more
Plain English This study looked at creating silver nanoparticles from a specific type of microalga and evaluated how these nanoparticles affect the chemical makeup and health benefits of the algal extract. The researchers found that the silver nanoparticles were mostly round and small, measuring between 10 and 50 nanometers, and had strong antibacterial effects, especially against bacteria like Staphylococcus. Additionally, these nanoparticles altered muscle activity in gastric tissue, suggesting they might help with digestive issues and could be used in health products and treatments.
Who this helps: This benefits patients with digestive problems and those seeking natural remedies for infections.
Fromto Nanomaterials: A Comparative Study of AgNPs Obtained from Two Extracts.

Nanomaterials (Basel, Switzerland)
Ivanova A, Todorova M, Petrov D, Petkova Z, Teneva O +8 more
Plain English This study looked at how silver nanoparticles (tiny particles of silver) can be made using two different sources: one from a bioreactor in Bulgaria and the other from a local health food store. The researchers found that the size and effectiveness of the particles varied, with the bioreactor source producing smaller particles (4-8 nanometers) and the store source producing larger ones (about 20 nanometers). The extracted particles showed good antibacterial properties and were effective at protecting proteins from heat damage.
Who this helps: This research benefits patients who need better treatments for infections and inflammation.
Chemical Characteristics and Biological Potential ofFruits.

Todorova M, Petkova N, Ivanov I, Tumbarski Y, Yanakieva V +4 more
Plain English This study looked at the fruits of the cherry laurel tree, specifically a variety called Novita, which grow in Southern Bulgaria. Researchers found that the fruit, especially when extracted with 96% ethanol, has a high amount of beneficial compounds called polyphenols and flavonoids, which are linked to strong antioxidant properties. These fruits also showed good ability to fight against various microorganisms, indicating that they might have health benefits.
Who this helps: This benefits health-conscious consumers, researchers, and the food industry.

Parzhanova A, Yanakieva V, Vasileva I, Momchilova M, Dimitrov D +2 more
Plain English This study looked at the qualities of three medicinal plants—thyme, cotton thistle, and hawthorn fruit—from the Rhodope Mountains in Bulgaria. It found that thyme had the highest levels of important nutrients like protein (11.30%), vitamin C (571 mg/100 g), and antioxidant compounds, making it particularly effective at fighting free radicals. These findings matter because they highlight the potential health benefits of these plants, especially thyme, which could be used for natural remedies to boost health.

Pharmaceuticals (Basel, Switzerland)
Milusheva M, Todorova M, Gledacheva V, Stefanova I, Feizi-Dehnayebi M +6 more
Plain English Researchers studied new types of drugs made from anthranilic acid to find alternatives for existing anti-inflammatory medications, which often have unpleasant side effects. They tested these new compounds and found that some of them were very effective at reducing inflammation, particularly in preventing protein damage, and they also showed promising results in other tests for inhibiting bacteria and muscle spasms. This is important because it could lead to safer and more effective treatments for people suffering from inflammatory diseases.
Who this helps: This helps patients with inflammatory conditions who need better medication options.
Physicochemical, microbiological, and sensory characteristics of probiotic Bulgarian yoghurts obtained by ultrafiltration of goat's milk.

Dushkova M, Kodinova S, Denkova Z, Yanakieva V, Menkov ND
Plain English This study looked at how making Bulgarian yoghurt from goat's milk using a special filtering process affects its health benefits and taste. The researchers found that when they used this filtering method, the yoghurt had more healthy bacteria and better taste, especially when they used specific starter cultures, showing up to 72% more lactic acid bacteria compared to regular yoghurts. This is important because it could lead to yoghurt that not only tastes better but also offers more health benefits.
Who this helps: This helps patients looking for healthier food options and doctors recommending probiotics.
