First drug delivery method developed for mitochondrial diseasesWhat do Huntington’s disease, Lou Gehrig’s disease (familial amyotrophic lateral sclerosis; the disease the physicist Stephen Hawking is suffering from) and Alzheimer’s disease have in common? The answer is mitochondria; these diseases are now called mitochondrial diseases.These incurable degenerative neurological or neuromuscular diseases, together with apoptosis (programmed cell death) and aging, are understood to occur largely at mitochondria sites. What then are mitochondria? Mitochondria (plural of mitochondr..

A research achievement first published in the world’s foremost chemistry journal Angewandte Chemie by a prominent Korean chemist and his coworkers has gained spotlight with additional coverage in Nature Nanotechnology, Chemistry World and other world’s leading chemistry and medical related journals.Prof. Kimoon Kim and his team at the Dept. of Chemistry have developed a novel approach to the production of polymeric nanocapsules, which has revolutionized our understanding of manufacturing nanocapsules. Furthermore, the research has generated much interest not only from chemists in t..

According to laws of quantum mechanics a physical entity may possess either particle-like or wave-like properties. A particle exhibits wave properties when one cannot tell the path the particle may take among different paths available. Once the path information is obtained, however, the wave-like properties of a particle are supposed to disappear. In any case, it is not possible to observe both the wave and particle properties simultaneously, which is known as complementarity of a physical entity. In early days around the advent of quantum mechanics the concept of complementarity was considere..

In the April1 issue of G&D, a Korean research team led by Dr. Kyong-Tai Kim (POSTECH) describes how melatonin production is coordinated with the body‘s natural sleep/wake cycles.Melatonin is a hormone produced by the pineal gland in the brain, which helps to regulate our bodies’ circadian rhythm (the roughly-24-hour cycle around which basic physiological processes proceed). Normally, melatonin production is inhibited by light and enhanced by darkness, usually peaking in the middle of the night. Melatonin‘s expression pattern is mimicked by a protein called AANAT, which is..
