Determination of antioxidant activity of wine byproducts and its correlation with polyphenolic content.

Angeles M Alonso et al.

Journal of agricultural and food chemistry, 50(21), 5832-5836 (2002-10-03)

It has been demonstrated that wine and other products derived from the grape have a high antioxidant capability; as a possible consequence of this, they may have potential benefits for health. The byproducts of the winemaking process represent a source

A highly sensitive and specific assay for determination of IGF-I bioactivity in human serum.

Jian-Wen Chen et al.

American journal of physiology. Endocrinology and metabolism, 284(6), E1149-E1155 (2003-02-27)

At present, the circulating bioactivity of insulin-like growth factor I (IGF-I) is estimated by immunological measurements of IGF-I levels. However, immunoassays ignore the modifying effects of the IGF-binding proteins (IGFBPs) on the interaction between IGF-I and the IGF-I receptor (IGF-IR).

Selectin-mucin interactions as a probable molecular explanation for the association of Trousseau syndrome with mucinous adenocarcinomas.

Mark Wahrenbrock et al.

The Journal of clinical investigation, 112(6), 853-862 (2003-09-17)

Trousseau described spontaneous, recurrent superficial migratory thrombophlebitis associated with occult cancers, and this was later correlated with disseminated microangiopathy (platelet-rich clots in small blood vessels). Trousseau syndrome often occurs with mucinous adenocarcinomas, which secrete abnormally glycosylated mucins and mucin fragments

Flocculation of Chlorella vulgaris induced by high pH: role of magnesium and calcium and practical implications.

Dries Vandamme et al.

Bioresource technology, 105, 114-119 (2011-12-21)

Microalgae hold great potential as a feedstock for biofuels or bulk protein or treatment of wastewater or flue gas. Realising these applications will require the development of a cost-efficient harvesting technology. Here, we explore the potential of flocculation induced by
