Dibutyl phthalate disrupts conserved circadian rhythm in Drosophila and human cells
PublicationPeople are constantly exposed to phthalates, due to their common use in the production of plastics, pharmaceuticals, cosmetics and skin care products. The ability of phthalates to disrupt endocrine signaling, leading to developmental, reproductive and metabolic defects, has been studied, yet how phthalates interfere with these biological functions is still unclear. To uncover DBP interacting molecular pathways, we raised Drosophila...

Mater-Bi/Brewers’ Spent Grain Biocomposites—Novel Approach to Plant-Based Waste Filler Treatment by Highly Efficient Thermomechanical and Chemical Methods
PublicationThermoplastic starch (TPS) is a homogenous material prepared from native starch and water or other plasticizers subjected to mixing at a temperature exceeding starch gelatinization temperature. It shows major drawbacks like high moisture sensitivity, poor mechanical properties, and thermal stability. To overcome these drawbacks without significant cost increase, TPS could be blended with bio-based or biodegradable polymers and...

Antimutagenic activity of white cabbage, raw and processed, juices towards food mutagens MeIQx and PhIP.
PublicationPrezentowane badania pokazały, że soki z kapusty wykazują bardzo silne właściwości przeciwutleniające. Najaktywniejszy był sok ze świeżej kapusty, który eliminował działanie użytych mutagenów w ponad 80%. Obróbka kulinarna nieco obniżała przeciwmutagenne właściwości pozostałych soków, ale i tak wykazywały one silne działanie ochronne.

Relationship between Chemical Structure and Biological Activity Evaluated In Vitro for Six Anthocyanidins Most Commonly Occurring in Edible Plants
PublicationNumerous studies have provided evidence that diets rich in anthocyanins show a broad spectrum of health benefits. Anthocyanins in nature are usually found in the form of glycosides. Their aglycone forms are called anthocyanidins. The chemical structure of anthocyanins is based on the flavylium cation, but they differ in the position and number of substituents. However, the bioactives and foods that contain them are frequently treated...
