Aqueous Block Copolymer Systems. Self-association, Phase Behaviour and Partitioning of Biomolecules

The phase and partitioning behaviour of aqueous block copolymer systems has been studied. The block copolymers used in this work were built up of three blocks. The middle block was poly(propylene oxide) (PPO) and hydrophobic. The two outer blocks constisted of poly(ethylene oxide) (PEO) chains and less hydrophobic. The amphiphilic property of this PEO-PPO-PEO block copolymers enable self-associati

Bioactivity of Medicinal Bolivian Andean plants. Effects on cell proliferation and related processes.

Popular Abstract in English Bolivia is the seventh richest country regarding biodiversity in the world. Also, in its territory more than 36 indigenous nations co-exist. Each of these has traditional medicines that are passed on from generation to generation orally. It has been estimated that the Bolivian flora has more than 20,000 plant species. Some of these are being explored for their pharmaceuColon cancer is common in both developed and developing countries, and is responsible for at least 600,000 deaths globally every year. It is therefore the second most common cause of cancer-related mortality. Extensive studies are being conducted worldwide to find more effective drugs that can be used in cancer treatment. In these studies, phytochemicals have proven to be good sources for drug dis
