The results show that optimal was achieved...

Inflammatory response represents one of the main mechanisms healing and tissue function restoration. On other hand, chronic inflammation leads to excessive secretion pro-inflammatory cytokines involved in onset several diseases. Oxidative stress condition may contribute worsening inflammatory state fall, increasing reactive oxygen species (ROS) production release. Polyphenols can counteract oxidative stress, modulating release toxic molecules interacting with physiological defenses, such as...

Potato is a staple food crop and an important source of dietary energy. Its tubers contain several essential amino acids, vitamins, minerals phytochemicals that contribute to the nutritional value this product. Recently, scientific interest has focused on purple red potatoes that, due presence anthocyanins, may be considered as natural powerful functional food. The aim study was evaluate characteristics pigmented varieties, types anthocyanins accumulated level both beneficial (vitamin C...

Microalgae are considered as a potential source of bioactive compounds to be used in different fields including food and pharmaceutical industry. In this context, fatty acid esters hydroxy-fatty acids (FAHFA) emerging new class with anti-inflammatory anti-diabetic properties. An existing gap the field algal research is limited knowledge regarding production these compounds. Our questions aimed determine whether microalga H. pluvialis can synthesize FAHFA levels increased when cultivated...

Long-term spatial missions will require sustainable methods for biomass production using locally available resources.
