Japanese researchers have successfully developed the world's first imaging method for visualising the behaviour of nicotine-adenine dinucleotide derivative (NAD(P)H), a key coenzyme, inside cells. This feat could ultimately facilitate the diagnosis of cancer and liver dysfunction and help to elucidate the mechanisms of neurological disorders.
A Japanese research team led by Drs. Hirokazu Komatsu and Katsuhiko Ariga of the International Center for Materials Nanoarchitectonics, in collaboration with Professors Yutaka Shido and Kotaro Oka of Keio University, have developed the world's first method for visualising the coenzyme nicotine-adenine dinucleotide derivative (NAD(P)H) inside cells.

Fluorescent imaging – used to identify and visualise cellular components by attaching a fluorescent substance – is an effective method for exploring vital phenomena.
Until now, however, the development of a method for visualising NAD(P)H, which plays a key role in various vital phenomena and diseases, has proven elusive due to the low reactivity of NAD(P)H to fluorescent substances.
The research group succeeded in developing a new fluorescent probe that specifically reacts with NAD(P)H, and achieved fluorescent imaging of NAD(P)H for the first time in the world, through the combined use of the new probe and an artificial promoter capable of promoting reactivity.
The new NADH imaging method could be used for various purposes, including: promoting early detection and supporting cancer treatment by detecting NADH leakage from invasive cancers; diagnosing liver dysfunction by detecting excessive NADH caused by cirrhosis of the liver; and elucidating the lack of NADH in patients with brain or neurological diseases such as Alzheimer's Disease, depression, and Parkinson's Disease.
The new method will also prove of great value in other life sciences research.
The research results will be published in a German scientific journal, Angewandte Chemie International Edition.

China's Loess Plateau was formed by wind alternately depositing dust or removing dust over the last 2.6 million years, according to a new report from University of Arizona geoscientists. The study is the first to explain how the steep-fronted plateau formed.

The leaves of the lotus flower, and other natural surfaces that repel water and dirt, have been the model for many types of engineered liquid-repelling surfaces. As slippery as these surfaces are, however, tiny water droplets still stick to them. Now, Penn State researchers have developed nano/micro-textured, highly slippery surfaces able to outperform these naturally inspired coatings, particularly when the water is a vapor or tiny droplets.
Enhancing the mobility of liquid droplets on rough surfaces could improve condensation heat transfer for power-plant heat exchangers, create more efficient...
Longer, more severe, and hotter droughts and a myriad of other threats, including diseases and more extensive and severe wildfires, are threatening to transform some of the world's temperate forests, a new study published in Science has found. Without informed management, some forests could convert to shrublands or grasslands within the coming decades.
"While we have been trying to manage for resilience of 20th century conditions, we realize now that we must prepare for transformations and attempt to ease...
A University of Oklahoma astrophysicist and his Chinese collaborator have found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.
The discovery of two supermassive black holes--one larger one and a second, smaller one--are evidence of a binary black hole and suggests that supermassive...
A team of European researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. The study is published today (27 August) in Ocean Science, an open access journal of the European Geosciences Union (EGU).
Though not as frequent as in the Pacific and Indian oceans, tsunamis also occur in the Mediterranean, mainly due to earthquakes generated when the African...
