Flavonoids and their properties to form chelate complexes

The medical properties of naturally occurring compounds such as flavonoids have been well known for many years. However, the discovery that complexes of flavonoids with metal ions are more effective than free flavonoids changed the course of chemistry research. Flavonoids can be effective drugs because of their potent chelating or neuroprotective, radical scavenging and anti-inflammatory properties. Our paper is a literature review about flavonoids and their complexes which are generally used in medicine and pharmacy

The author of the text shows the importance of valuing and reinvention of authorities in today’s world whose educational and scientific research will be carried out in the light of Pampaedia

Brood hiding test: a new bioassay for behavioral and neuroethological ant research

We describe a new bioassay for behavioral and neuroethological ant research, the brood hiding test. A group of adult ants is taken out of the nest, confined together with brood and exposed to strong light. Ants may interact with brood, and, in particular, transport it to the provided shadowed area. The brood hiding test may be accompanied by administration of neuroactive compounds and/or by measurements of their levels in the brain and/or in specific brain structures. During pilot tests with workers of Formica polyctena the values of the score quantifying ant behavior were positively correlated with the group size
