Natural gases a therapy for heart disease?

An understanding of the interaction between hydrogen sulphide (the 'rotten eggs' gas) and nitric oxide, both naturally occurring in the body, could lead to the development of new therapies and interventions to treat heart failure

2011-06-30
(Press-News.org) Research carried out by scientists from the Peninsula Medical School at the University of Exeter and the National University of Singapore has analysed the complex 'cross talk' between hydrogen sulphide (H2S ) and nitric oxide (NO), both gasses that occur naturally in the body, and found that the interaction may offer potential strategies in the management of heart failure.

The research is published in the leading international journal Antioxidants and Redox Signaling.

Both gases interact naturally with each other within the body and the balance between the two and other chemical compounds has influence on health. The research team found that by modulating how H2S and NO interact, a positive affect was produced for heart health.

The two gases were found to interact together to form a thiol-sensitive compound (linked to the sulphur in H2S) which produces inotropic (muscular contraction) and lusitropic (muscular relaxation) effects in the heart. This crosstalk suggests that there is the potential to produce a molecule that may be of benefit to the heart and which could be the basis of a new drug therapy based on elements that occur naturally in the body.

The study also offers a new perspective on gaseous neurotransmitters, in which the function of cells is influenced by the interaction of the two gases.

Prof. Matt Whiteman, joint author from the Peninsula Medical School, commented: "Our findings are potentially very exciting and offer a novel insight into understanding how and why the heart fails. This could lead to new treatment and management strategies of heart failure, such as molecules which release H2S. By altering the ratio of H2S and NO, two naturally occurring physiological gases in the heart and perhaps the rest of the cardiovascular system, we have the potential to manipulate heart and vascular function. There is huge potential in the continued development of H2S delivery systems either through pharmacological means or through dietary intervention."

Farm animal disease to increase with climate change

2011-06-30
Researchers looked at changes in the behaviour of bluetongue – a viral disease of cattle and sheep - from the 1960s to the present day, as well as what could happen to the transmission of the virus 40 years into the future. They found, for the first time, that an outbreak of a disease could be explained by changes to the climate. In Europe, more than 80,000 outbreaks of bluetongue were reported to the World Animal Health Organisation between 1998 and 2010, and millions of animals died as a result of the disease. Bluetongue was previously restricted to Africa and Asia, ...

Osteoarthritis incidence significantly higher among US military personnel

2011-06-30
New research shows significantly higher osteoarthritis (OA) incidence rates in military populations than among comparable age groups in the general population. The magnitude of the difference in OA rates between military service members and the general population also increased with advancing age category. Black service members had higher OA rates than white military personnel or those in other race categories according to the study findings published in Arthritis & Rheumatism, a peer-reviewed journal of the American College of Rheumatology (ACR). Close to 27 million ...

Moving microscopic vision into another new dimension

2011-06-30
Scientists who pioneered a revolutionary 3-D microscope technique are now describing an extension of that technology into a new dimension that promises sweeping applications in medicine, biological research, and development of new electronic devices. Their reports on so-called 4-D scanning ultrafast electron microscopy, and a related technique, appear in two papers in the Journal of the American Chemical Society. Chemistry Nobel Laureate Ahmed H. Zewail and colleagues moved high-resolution images of vanishingly small nanoscale objects from three dimensions to four dimensions ...

Recycling: A new source of indispensible 'rare earth' materials mined mainly in China

2011-06-30
That axiom of sustainability — "recycle and reuse" — could help ease concerns about a reliable supply of substances, indispensible for a modern technological society, that are produced almost exclusively in the Peoples' Republic of China. That's the conclusion of a study on these so-called "rare earth" elements in the ACS journal Environmental Science & Technology. Xiaoyue Du and Thomas E. Graedel note that the dozen-plus rare earth elements (REEs) have unique physical and chemical properties making them essential for defense applications, computers, cell phones, electric ...

New rapid test tells difference between bacterial and viral infections

2011-06-30
Scientists are reporting development and successful testing of a rapid and accurate test to tell the difference between bacterial and viral infections. Those common afflictions often have similar symptoms but vastly different treatments — antibiotics work for bacterial infections but not for viruses. The report appears in ACS' journal Analytical Chemistry. Robert Marks, Daria Prilutsky, and colleagues cite the importance of determining the source of an infection in order to quickly start the right treatment. If left untreated until results of a throat culture, for instance, ...

Culture influences people's response to climate change

2011-06-30
How people choose to consume resources and use contraception influences their responses to climate change, according to a team of psychologists. Janet K. Swim, professor of psychology, Penn State, and her colleagues report that growing consumption and growing population are two significant contributors to human impact on the environment. Both substantially increase carbon dioxide levels in the atmosphere, the researchers report in a special issue of American Psychologist that focuses on how psychology contributes to understanding and addressing global climate change. "Engaging ...

Pinpointing the origin of corpses, fingering fake cheese and more -- with 'isoscapes'

2011-06-30
An emerging field of science termed "isoscapes" is making it possible to pinpoint the geographical origins of illegal drugs, trafficked endangered animals, dismembered human body parts at crime scenes, and even pricey scotch whiskey and cheese, according to an article in the current edition of Chemical & Engineering News (C&EN), the American Chemical Society's weekly newsmagazine. In the article, Sarah Everts, C&EN European correspondent, explains how isoscapes has even led to development of one of the newest and most unusual maps of the world. It is a map showing the ...

American Chemical Society podcast: Tiny generator powers wireless device

2011-06-30
WASHINGTON, June 29, 2011 — Imagine a new genre of tiny implantable sensors, airborne and stationary surveillance cameras and sensors and other devices that operate without batteries on energy collected from the motion of a heart beat and have wireless communications capability. And the power plant for those devices is a "nanogenerator" that could even produce energy to charge an iPod from the movements of a person walking down the street. That's the topic of a new episode in the American Chemical Society's (ACS) award-winning "Global Challenges/Chemistry Solutions" podcast ...

Rutgers study: Third of N.J. immigrant children, many adult newcomers lack health insurance

2011-06-30
NEW BRUNSWICK, N.J. – One-third of immigrant children and more than 70 percent of foreign-born, nonelderly adults living in New Jersey five years or less lack health coverage, a Rutgers statewide survey finds. The report, "Health, Coverage and Access to Care of New Jersey Immigrants," by the Rutgers Center for State Health Policy (CSHP), also concludes immigrants face significant access-to-care barriers and their lack of health insurance is a much larger problem than for New Jerseyans born in the United States. The research describes the health profile, insurance status ...

Genetic 'conductor' involved with new brain cell production in adults

2011-06-30
A team of North Carolina State University researchers has discovered more about how a gene connected to the production of new brain cells in adults does its job. Their findings could pave the way to new therapies for brain injury or disease. Most areas of the brain do not generate new brain cells, or neurons, after we are born. One exception is the olfactory bulb, the brain's scent processor, which continually produces new neurons. Dr. Troy Ghashghaei, assistant professor of neurobiology, had previously found a gene – known as Foxj1–connected to the production of an area ...
