Toward a better cyanide antidote for terrorist attacks and other mass casualty events

2013-01-30
(Press-News.org) In an advance toward closing a major gap in defenses against terrorist attacks and other mass casualty events, scientists are reporting discovery of a promising substance that could be the basis for development of a better antidote for cyanide poisoning. Their report, which describes a potential antidote that could be self-administered, much like the medication delivered by allergy injection pens, appears in ACS' Journal of Medicinal Chemistry.

Steven E. Patterson, Ph.D., and colleagues at the University of Minnesota Center for Drug Design explain that the only existing antidotes for cyanide — recognized as a high-risk substance for potential use by terrorists — must be administered by intravenous infusion. That procedure requires highly trained paramedical personnel and takes time. Cyanide, however, is a fast-acting poison. In a situation involving mass casualties, only a limited number of victims could be saved. Patterson's team thus sought an antidote that could be administered by intra-muscular (IM) injection, a simpler procedure that could be administered rapidly to a large number of victims or even be self-administered.

Their report describes discovery of a substance, sulfanegen TEA, "which should be amenable for development as an IM injectable antidote suitable for treatment of cyanide victims in a mass casualty setting. Further development, including efficacy in lethal cyanide animal models, will be reported at a later date."

Why some immigrants get citizenship

2013-01-30
CAMBRIDGE, MA -- For immigrants, the path to citizenship in many countries is filled with hurdles: finding a job, learning the language, passing exams. But for some people, the biggest obstacle of all may be one they cannot help: their country of origin. That's one conclusion of a methodologically innovative study of European immigrants suggesting that, other qualifications being equal, migrants from certain countries may be roughly 40 percent less likely than others to gain citizenship. Even if an immigrant has obtained a good education and job, and solid language ...

First mobile app for green chemistry fosters sustainable manufacturing of medicines

2013-01-30
Mention mobile applications, or mobile apps, and people think of games, email, news, weather, productivity and other software for Apple, Android and other smart phones and tablet computers. But an app with broader impact — the first mobile application to foster wider use of the environmentally friendly and sustainable principles of green chemistry — is the topic of a report in the American Chemical Society's new journal, ACS Sustainable Chemistry & Engineering. Sean Ekins, Alex M. Clark and Antony Williams point out that the companies that manufacture medicines, electronics ...

TV viewing and sedentary lifestyle in teens linked to disease risk in adulthood

2013-01-30
A team of scientists at Umeå University, in collaboration with colleagues in Melbourne, Australia, have found that television viewing and lack of exercise at age 16 is associated with the risk of developing metabolic syndrome at 43 years age. Metabolic syndrome is a name for the disorder of metabolism - a combination of abdominal obesity, elevated blood lipids, hypertension and impaired glucose tolerance - which provides for a significantly increased risk of developing type 2 diabetes, stroke and cardiovascular disease. It has previously been shown that lack of physical ...

Prehistoric humans not wiped out by comet, say researchers

2013-01-30
Comet explosions did not end the prehistoric human culture, known as Clovis, in North America 13,000 years ago, according to research published in the journal Geophysical Monograph Series. Researchers from Royal Holloway university, together with Sandia National Laboratories and 13 other universities across the United States and Europe, have found evidence which rebuts the belief that a large impact or airburst caused a significant and abrupt change to the Earth's climate and terminated the Clovis culture. They argue that other explanations must be found for the apparent ...

Rats, like humans, return to drinking once punishment is removed

2013-01-30
Philadelphia, PA, January 30, 2013 – Once heavy drinking impairs function, a variety of punishment-related threats may motivate people to stop drinking: spouses may threaten divorce, employers may threaten job loss, and courts threaten drunk drivers with losing their driver's license or incarceration. In the face of these threats, many alcohol abusers refrain from drinking, but relapse is very common when the threats of punishment fade, particularly when exposed to alcohol-associated environments (contexts). A new study by researchers at the National Institute on Drug ...

Study reveals significance of second trimester markers for Down's syndrome

2013-01-30
A new analysis has found that some second trimester markers for Down's syndrome that are detected by ultrasound are more telling than others. Published early online in Ultrasound in Obstetrics & Gynecology, the study's results will help adjust pregnant women's risks for having a child with the condition. Screening for Down's syndrome is offered to all pregnant women, who start out with a background risk based on their age. Certain features detected during a second trimester ultrasound exam are potential markers for Down's syndrome, and they include dilated brain ventricles, ...

Mixed forest provides beneficial effects

2013-01-30
Forestry and nature conservation can benefit from promoting more different varieties of trees, according to a new study in which researchers from the University of Gothenburg, Sweden, were involved. Modern forestry is based largely on monocultures – usually pine or spruce trees in Sweden – mainly because this is seen to be more rational. However, a forest also contributes ecosystem services other than just wood production, such as biological diversity, carbon sequestration and berries. A new study by the Swedish University of Agricultural Sciences (SLU) and Future Forests ...

Research study: Whistle away the need for diapers

2013-01-30
Western babies are potty trained later these days and need diapers until an average of three years of age. But even infants can be potty trained. A study by researchers at Sahlgrenska Academy, University of Gothenburg, Sweden, followed 47 infants and their mothers in Vietnam – where potty training starts at birth and the need for diapers is usually eliminated by nine months of age. Not only does eliminating the need for diapers save money and remove one practical chore for parents, but the baby's ability to control its bladder improves efficiency and reduces the risk ...

Excessive alcohol use when you're young could have lasting impacts on your brain

2013-01-30
Excessive alcohol use accounts for 4% of the global burden of disease, and binge drinking particularly is becoming an increasing health issue. A new review article published Cortex highlights the significant changes in brain function and structure that can be caused by alcohol misuse in young people. Functional signs of brain damage from alcohol misuse in young people mainly include deficits in visual learning and memory as well as executive functions. These functions are controlled by the hippocampus and frontal structures of the brain, which are not fully mature until ...

Light yet safe contender for city streets

Light yet safe contender for city streets
2013-01-30
This press release is available in German. Up to now, it has been a case of "either/or." On the one hand, we have the typical ultra-compact, lightweight electric car, where designers have had to compromise on safety. With larger e-cars on the other hand, the heavier frames and crumple zones come at the expense of battery range. But now researchers as well as engineers from some of Germany's top technology firms are looking to create the best of both worlds. The aim of the Visio.M project is to develop a mobility concept for an efficient electric vehicle, making ...
