Microalgae are well known for their biotechnological potential, namely with regard to bioactive lipidic components-especially carotenoids and polyunsaturated fatty acids (PUFA), well-known for therapeutic applications based on their antioxidant capacity. The aim of this work was to evaluate the influence of four distinct food-grade solvents upon extractability of specific lipidic components, an...

The genome of Ceriporiopsis subvermispora includes 13 manganese peroxidase (MnP) genes representative of the three subfamilies described in ligninolytic fungi, which share an Mn(2+)-oxidation site and have varying lengths of the C-terminal tail. Short, long and extralong MnPs were heterologously expressed and biochemically characterized, and the first structure of an extralong MnP was solved. I...

UNLABELLED The red seaweed Phyllophora pseudoceranoides (Gmelin) New. et Tayl, commonly found in the Romanian Black Sea coastal waters, has not been studied regarding its chemical composition and biological activities. AIMS The aim of the present study was to isolate, characterize and assess the in vitro antioxidant activity of the crude polysaccharide from P. pseudocerano ides. MATERIALS A...

An amperometric immunoanalysis system based on monoclonal antibodies immobilized on Sepharose beads and packed into a micro-immunocolumn was developed for the quantification of microcystin-LR. Microcystin-LR (MCLR) was used as a reference microcystin variant. Inside the immunocolumn, free microcystins and microcystin-horseradish peroxidase (tracer) were sequentially captured by the immobilized ...

Purpose: To evaluate the total phenolic content and antioxidant potential of the methanol extracts of aerial parts and roots of Thymus sipyleus Boiss and also to determine some phenolic compounds using a newly developed and validated reversed phase high performance liquid chromatography (RP-HPLC) method. Methods: The total phenolic concentration of the extracts were determined using Folin Cioca...

In this work, an evaluation of the biological activities of Globularia alypum L. extracts and their global chemical composition was realized. Extracts from G. alypum were obtained by two extraction methods. The composition of polyphenols (8.5-139.95 g gallic acid equivalent/Kg of dry mass), tannins (1.39-18.65 g catechin equivalent/Kg of dry mass), anthocyanins (8.17-70.69 mg cyanidin equivalen...

Title of Document: ANTIOXIDANT AND ANTIPROLIFERATIVE PROPERTIES OF SELECTED GRAPE SEED EXTRACTS Raquel Zorah Bloom, Master of Science, 2009 Directed By: Associate Professor Dr. Liangli Yu Nutrition and Food Science This study examined chardonnay, muscadine, concord, and ruby red grape seed oil and flour extracts for antioxidant and anti-proliferative properties. The extracts were tested for tot...

In the present work we investigated, for the first time, the anti-inflammatory activity and the antioxidant properties of aqueous and ethanolic extracts, obtained from stem bark of Geoffroea decorticans (Gill. ex Hook. et Arn.) Burk. (Fabaceae). G. decorticans, commonly known as “chañar” or “chañarcillo”, is a traditional argentinean plant used as emollient, balsamic, antitussive, expectorant a...
