Comparing healing effect against ulcerative colitis and toxicological effects of Rosmarinus officinalis: A comprehensive in vivo study of an edible plant in rats.

Ulcerative colitis (UC) is a chronic and inflammatory disorder of the gastrointestinal (GI) tract. UC usually worsens the daily life of the patient and may sometimes become mortal. There is no known remedy discovered against UC, yet.

Chitosan and carboxymethyl cellulose based magnetic nanocomposites for application of peroxidase purification.

Recently, protein purification methods have a very wide area of research. Many of these methods are both expensive and multi-stage methods, that are needed in specific equipment. In this study, biopolymer coated magnetic nanoparticles, carboxymethyl cellulose (CMC) and chitosan (CH) coated FeO (magnetite) nanocomposites, are used in a new purification process.

Evaluation of the efficiency and safety in cosmetic products.

Chemicals used in cosmetics have to interact with enzymes for beneficial or destroy purpose after they enter in our body. Active sections of enzymes that catalyze reactions have three dimensions and they are active optically. When these limitations of catalytic sections are considered, it may be considered that defining geometric specifications of chemical materials and functional groups they contain may contribute on safety evaluations of cosmetic products.
