Biomimetic synthesis of functional silver nanoparticles using hairy roots of Panax ginseng for wheat pathogenic fungi treatment.

Presently, multifunctional silver nanoparticles (AgNPs) show a rapid growth in various commercial applications, leading to increasing demand for new eco-friendly manufacturing technologies. An array of genetic engineering tools can be used to increase the yield in the production of AgNPs using various biological systems. The present study reports a green chemistry approach for the biological synthesis of AgNPs using extracts from non-transformed callus, rolC-transgenic callus and hairy roots of Panax ginseng and an evaluation of their efficacy against crop-damaging fungal pathogens.

[Early encounters of German-language explorers with the Tibetan medicine in Siberia in the modern era].

The spreading of Tibetan Buddhism and with it the Tibetan medicine in the region east of Lake Baikal, goes back to the 17th century. At the beginning of the 18th century, German speaking scholars were among the first to undertake scientific expeditions through Siberia. As such they were amongst the first scientists of the modern era who encountered the traditions, concepts, and therapeutic methods of Tibetan medicine.

[Hepatoprotective effect of Tibetan remedy "Dig-Da-Shi-Tan"].

In experiments on albino rats with toxic hepatitis due to their exposure to tetracycline hydrochloride it was shown that a course of therapeutic and preventive administration of Dig-da-shi-tan decoction had a strong hepatoprotective effect. Antioxidative, membrane integrative, cholagogic and antiinflammatory activities of the remedy were revealed.
