Genetically engineered blood protein can be used to split water into oxygen and hydrogen
12-01-2006 · EurekAlert!Scientists have combined two molecules that occur naturally in blood to engineer a molecular complex that uses solar energy to split water into hydrogen and oxygen, says research published today in the Journal of the American Chemical Society.

- Common blood pressure drug treats muscular dystrophy in mice
01-21-2007 · EurekAlert!
Researchers at Johns Hopkins have shown that a drug commonly used to lower blood pressure reverses muscle wasting in genetically engineered mice with Marfan syndrome and also prevents muscle degeneration in mice with Duchenne muscular dystrophy. The results are reported online this week at Nature Medicine.

- Alloy of hydrogen and oxygen made from water
10-26-2006 · EurekAlert!
Researchers have used X-rays to dissociate water at high pressure to form a solid mixture -- an alloy -- of molecular oxygen and molecular hydrogen. The work, by a multi-institutional team that includes Russell Hemley and Ho-kwang Mao of Carnegie's Geophysical Laboratory, appears in the October 27 issue of Science.

- Sea cucumber protein used to inhibit development of malaria parasite
12-20-2007 · EurekAlert!
Scientists have genetically engineered a mosquito to release a sea-cucumber protein into its gut which impairs the development of malaria parasites, according to research out today (Dec. 21) in PLoS Pathogens. Researchers say this development is a step towards developing future methods of preventing the transmission of malaria.

- Learning how nature splits water
11-03-2006 · EurekAlert!
An international team led by scientists from the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) pieced together high-resolution (approximately 0.15 Еngstrom) structures of a Mn4Ca cluster found in a photosynthetic protein complex. Their work could help researchers synthesize molecules that mimic this catalyst, which is a central focus in the push to develop clean energy technologies that rely on sunlight to split water and form hydrogen to feed fuel cells or other non-polluting power sources.

- Treatment with SN reduces injury to the brain following stroke
12-13-2007 · EurekAlert!
Stroke is the term used to describe deteriorating brain function due to either the leaking of blood vessels (hemorrhage) or oxygen deprivation (ischemia) in the brain. A new report has revealed a beneficial effect of the protein secretoneurin in rat with ischemia-induced stroke, leading the authors of the study to suggest that SN holds promise as a small-molecule drug for the treatment of individuals who have had a stroke.

- A type of antioxidant may not be as safe as once thought
09-04-2007 · EurekAlert!
According to new research at the University of Virginia Health System, N-acetylcysteine (NAC), an antioxidant commonly used in nutritional and body-building supplements, can form a red blood cell-derived molecule that makes blood vessels think they are not getting enough oxygen. This leads to pulmonary arterial hypertension (PAH), a serious condition characterized by high blood pressure in the arteries that carry blood to the lungs.

- Scientists discover novel way to remove iron from ferritin
11-02-2007 · EurekAlert!
A new study led by Children's Hospital Oakland Research Institute senior scientist, Elizabeth Theil, PhD, is the first to suggest that a small protein or heptapeptide could be used to accelerate the removal of iron from ferritin. The results of this study may help scientists develop new medications that dramatically improve the removal of excess iron in patients diagnosed with blood diseases such as B-Thalassemia (Cooley's anemia) or sickle cell disease.

- Mice with Alzheimer's disease suffer 'silent' seizures
09-05-2007 · EurekAlert!
Mice genetically engineered to have a disease like Alzheimer's have "silent" seizures that appear related to cellular changes involving the excess accumulations of the protein amyloid beta, said researchers from the Gladstone Institute of Neurological Disease and Baylor College of Medicine in a report that appears in today's issue of the journal Neuron.

- Severe heart attack damage limited by hydrogen sulfide
09-18-2007 · EurekAlert!
Heart attacks and even surgery can cause severe heart-tissue and cell damage due to oxygen deprivation. A new study finds that hydrogen sulfide can prevent such damage after blood flow is restored.
