Two of the most commonly prescribed drugs for treating HIV (antiretroviral drugs)–nevirapine and efavirenz–can both raise levels of the “good type” of cholesterol (HDL cholesterol), but nevirapine raises it higher than efavirenz, according to a new study by van Leth and colleagues published in the launch issue of PLoS Medicine. “These data suggest that nevirapine may be preferable to efavirenz in HIV-infected adults who have increased cardiovascular risk,” says Andrew Carr, an HIV specialist a
The prevalence of Helicobacter pylori (a type of bacteria associated with gastrointestinal disorders) is high among patients about to undergo weight loss surgery, and treatment to eradicate the bacterial infection before surgery may be beneficial, according to an article in the October issue of The Archives of Surgery, one of the JAMA/Archives journals.
The number of obese and morbidly obese Americans is steadily increasing, according to background information in the article.
French and Australian scientists resume measurements of Antarctic waters south of Australia this week to assess their capacity as a massive oceanic sponge to absorb greenhouse gases and store them away for hundreds or perhaps thousands of years.
France and Australia have a joint research program taking measurements from the Antarctic supply ship L’Astrolabe during its voyages between Hobart and the French base at Dumont D’Urville. L’Astrolabe, equipped with a full
From 10 to 14 October the ion engine of ESA’s SMART-1 carried out a continuous thrust manoeuvre in a last major push that will get the spacecraft to the Moon capture point on 13 November.
SMART-1, on its way to the Moon, has now covered more than 80 million kilometres. Its journey started on 27 September 2003, when the spacecraft was launched on board an Ariane 5 rocket from Europe’s spaceport in Kourou, French Guiana. Since then, it has been spiralling in progressively larger orbit
Technologies from space provide new solutions for food handling on Earth. In exchange travellers in space will get gourmet menus from Earth to cheer them up during long space missions. At the International Food Exhibition SIAL in Paris this week, ESA presents an exchange of ideas between food and space, including recipes for travellers to Mars.
“Every year we research and develop a number of pioneering technologies needed for space exploration. Many have potential for innovative s
Heraeus at the plastics industry`s trade fair K in Düsseldorf – Infrared emitters for every application
In the plastics industry today, when extruding foil, forming PET bottles, riveting automotive interior panels, drying the print on yoghurt cups, or sealing tank containers, an increasingly important tool is the unique source of heat known as infrared radiation. Heraeus Noblelight is known for its innovative product development and application of infrared heat systems. The co
New research may advance the nanoelectronics field
Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory and their collaborators have discovered that a short, organic chain molecule with dimensions on the order of a nanometer (a billionth of a meter) conducts electrons in a surprising way: It regulates the electrons’ speed erratically, without a predictable dependence on the length of the wire. This information may help scientists learn how to use nanowires to
People with diabetes mellitus have three to four times the risk of developing liver cancer, and more than twice the risk of developing pancreatic cancer than non-diabetic individuals, according to research presented today at the Third Annual Frontiers in Cancer Prevention Research Meeting in Seattle.
Marie-Claude Rousseau, lead author on the study, compared 3,288 men diagnosed with 12 different cancer types to 509 healthy individuals, in order to determine whether those reporting
A drug that reduces symptoms of systemic lupus in mice may turn out to be effective against hardening of the arteries and thus prevent heart attacks, according to two poster presentations today at the American College of Rheumatology meeting in San Antonio.
Nilamadhab Mishra, M.D., of Wake Forest University Baptist Medical Center, said the drug, called Trichostatin A or TSA, “may have a therapeutic benefit in atherosclerosis,” which causes coronary artery disease by blocking ke
FOKUS’ spinoff iptelorg GmbH attracts international attention. Iptelorg, BridgePort Networks, and Telio provide interoperability for next generation SIP based solutions.
iptelorg, the leading provider of SIP based server solutions for large service providers, announced it has been named to the “Pulver 100” along with its customer BridgePort Networks and partner Telio. The “pulver 100” features private companies in the communications sector that have substantial real-world
A new study that will look at 50,000 sisters of women diagnosed with breast cancer opened today for enrollment across the United States. The Sister Study, conducted by the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health, will investigate environmental and genetic causes of breast cancer. The Sister Study is the largest study of its kind to look at breast cancer risk factors.
Women of all backgrounds and ethnic groups are elig
The number of people who succumb to identity thieves’ “phishing” e-mails could go way up if immediate action isn’t taken to preempt the next generation of attacks, according to Markus Jakobsson, an Indiana University School of Informatics researcher.
A report by cybersecurity expert Jakobsson describing worst-case phishing scenarios was recently cited by Howard Schmidt, chief information security officer for eBay Inc., during his testimony before a U.S. Congressional subcomm
Patients infected with the hepatitis C virus (HCV) are six times as likely to develop non-Hodgkin’s lymphoma (NHL) than individuals that are virus free, according to research presented today at the Third Annual Frontiers in Cancer Prevention Research meeting. HCV infected patients have a seventeen fold higher risk for developing diffuse large B-Cell lymphoma, researchers from British Columbia documented. Diffuse large B-cell lymphoma is the most common variety of NHL, comprising approximate
Breast cancer is the most frequent form of cancer in women around the world. The fact that this cancer is more frequent in the developed world suggests that life style and environmental factors may be involved. Nutritional factors are particularly important, given people’s continual exposure through dietary habits. Among them, dietary fats are the main element involved in breast cancer. Fats do not cause cancer, however some of them, such as animal fats or certain vegetable fats, accelerate th
The Flanders Interuniversity Institute for Biotechnology (VIB) and Ghent University have started up a new biopharmaceutical company named Peakadilly nv. Peakadilly will develop and market a new generation of molecular diagnostics − so-called protein bio-markers − using innovative proteomics technology developed by the research group under the direction of Joël Vandekerckhove. The markers can be used in the development of medicines, making the process much more efficient, effective a
The active, younger population of Liverpool, who suffer from arthritis or chronic injury can now benefit from knee replacement surgery much earlier in life due to the latest implant technology, called Oxinium™, which has recently been made available to everyone in the UK after 11 years of tests.
Mrs Linda Wood, a 49 year-old voluntary playgroup leader from Liverpool, received one of the first Oxinium knee implants in the UK, after suffering with increasing chronic pain in her left
