Abstract: A flexible printed circuit board (PCB) has stretchability and durability. The flexible PCB includes: a first polymer substrate having flexibility, stretchability, or elasticity; a second polymer substrate having flexibility, stretchability, or elasticity; a conductive track disposed between the first and second polymer substrates and including metal nanowires; and a cured silane coupling agent which bonds the conductive track to at least one of the first and second polymer substrates.

Abstract: The present invention discloses methods for analyzing the activity of lipoxygenase by using polyunsaturated lysophosphatidylcholine as a water-soluble substrate. In these methods, lipoxygenase activity can be analyzed without using detergents in reaction solution.

Abstract: The present invention relates to an anti-inflammatory composition containing docosahexaenoyl lysophosphatidylamine as an active ingredient. Particularly, one of polyunsaturated lysophosphatidylcholines, docosahexaenoyl lysophosphatidylcholine inhibits intracellular NO generation mediated by lipopolysaccharide and suppresses zymosan A induced peritonitis in vivo, suggesting that it has excellent anti-inflammatory effect but has no cytotoxicity, so that it can be effectively used for prevention and treatment of inflammatory disease.

Abstract: The present invention relates to an extract of Petasites japonicus having antioxidant activity, and more particularly, to an extract of Petasites japonicus having antioxidant activity which is extracted using an alcohol and an antioxidant for the prevention and treatment of a brain disease comprising the extract as an effective ingredient. The Petasites japonicus extract according to the present invention has excellent antioxidant activity, relief of neurotoxicity and neuroprotective effect and thus, can be usefully used in the prevention and treatment of brain diseases such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, hypoxic-ischemic injury and chronic spinal cord injury.
