Findings may explain link between lifestyle and heart disease
A less active brain serotonin system is associated with early hardening of the arteries, according to a study presented today by University of Pittsburgh researchers at the 64th Annual Scientific Conference of the American Psychosomatic Society in Denver. These findings, which are the first to establish a link between serotonin messages in the brain and atherosclerosis, could lead to an entirely new strategy for preven
Artery disease tied to hostility for wives, loss of control for husbands
Hardening of the coronary arteries is more likely in wives when they and their husbands express hostility during marital disagreements, and more common in husbands when either they or their wives act in a controlling manner.
Those are key findings of a study of 150 healthy, older, married couples – mostly in their 60s – conducted by Professor Tim Smith and other psychologists from the University o
One of the most powerful antioxidants is truly a double-edged sword, say researchers at Ohio State University who studied how two forms of vitamin E act once they are inside animal cells.
In the past couple of decades, a slough of studies has looked at the benefits of vitamin E and other antioxidants. While a considerable amount of this research touts the advantages of consuming antioxidants, some of the studies have found that in certain cases, antioxidants, including vitamin E, may ac
Everyday ice used to chill that glass of lemonade has helped researchers better understand the internal structure of icy moons in the far reaches of the solar system. A research team has demonstrated a new kind of “creep” or flow in a high-pressure form of ice by creating in a laboratory the conditions of pressure, temperature, stress, and grain size that mimic those in the deep interiors of large icy moons.
High-pressure phases of ice are major components of the giant icy moons of the o
The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) has demonstrated that ventilated automotive seats not only can improve passenger comfort but also a vehicle’s fuel economy. That’s because ventilated seats keep drivers and passengers cooler, so they need less air conditioning to be comfortable.
NREL’s Vehicle Ancillary Loads Reduction team has been working with industry to try to reduce fuel consumption from air conditioning in cars and
Shipping companies can route ships more safely and efficiently. Ocean search-and-rescue can operate more effectively. Meteorologists and climatologists now have a tool to provide long-range weather prediction more accurately. Navies too can perform more accurate anti-submarine surveillance. And environmental managers now have a mechanism to track pollution, algal blooms, or emergent situations such as oil spills. And, this is all due to a unique three-dimensional ocean model that has been developed
A fake peregrine and a radar-activated cannon work better at keeping birds away from oil sands tailings than the current system, says new research from the University of Alberta.
Oil sands mining is one of several industrial activities that produces waste dangerous to waterfowl. The birds, such as ducks, geese and swans, are attracted to freshwater ponds for foraging, roosting and nesting, and as stopover sites during migration. Spring migration is a particular problem in nort
A scientific study reported in two related articles in the Journal of Drug Issues raises serious doubts about the nation’s illegal drug use surveillance programs. Scientists, policy makers, and the media depend on surveys to identify the extent of drug use nationwide. The study documented how drug use surveys may not accurately reflect changes in drug use, but be more related to how willing a respondent is to disclose the extent and type of drug use.

Siemens Medical Solutions introduces new IT-based solutions for magnetic resonance tomography at the ECR. These so-called syngo MR applications simplify workflows in clinical routine, for example, imaging of the spine, the thorax or diffusion-weighted imaging in the body and 3D acquisitions with various contrasts. These applications enable faster and more accurate diagnosis and improve the efficiency of the hospital. The new syngo MR applications are based on Tim (Total imaging matrix) tec
Syngo iPilot supports physicians during interventions
Global Positioning Systems for cars search for the fastest and most practical way to reach a specific destination. The software function syngo iPilot from Siemens Medical Solutions (Med) works in a similar way: It supports the physician in guiding the catheter as smoothly as possible through the arteries during interventional procedures. During this time, syngo iPilot visualizes the two-dimensional fluoro image, which appears in
Studies prove it: with IT, radiology departments can save up to 50 percent on time alone Today’s increasing cost pressure in the healthcare sector requires comprehensive solutions that increase the quality of care and reduce cost at the same time. In addition to the use of innovative medical systems, information technology plays an important role in this effort: only high-performance software architectures are able to display, automate and optimize the highly complex processes of ho
Siemens Medical Solutions remains true to its course of innovation: The company works continuously on future technologies and solutions for ultrasound imaging. The newest innovations are presented by Siemens at the European Congress of Radiology (ECR) in Vienna from March 3 to 7, 2006. Siemens will highlight Cadence CPS technology (Contrast Pulse Sequencing) which provides excellent contrast detection and good specificity, and is also the enabling technology for molecular medicine. In addition, the
Storage of up to 5000 images on Siremobil Compact L
Siemens Medical Solutions introduces an updated version of the mobile C-arm Siremobil Compact L. The system’s numerous improvements in design, image chain, and workflow integration provide for optimal clinical applications.
The improved user interface of the mobile C-arm Siremobil Compact L presents a comprehensive operating menu, self-explanatory keyboard commands and easy navigation via a window-based display. It al
The circumstances around their dying – and not the location – are what matter most to terminally ill Canadians, says Queen’s University Professor of Medicine Daren Heyland.
A national study on end-of-life care led by Dr. Heyland, research director in the Department of Medicine at Kingston General Hospital, shows that patients rated dying at home as less important than having confidence and trust in the doctors looking after them. The results may cast doubt on current efforts to s
Newly diagnosed cancer patients who use the Internet to gather information about their disease have a more positive outlook and are more active participants in their treatment, according to a new Temple University study published in the March 2006 issue of the Journal of Health Communication.
“This is the first study to look at the relationship between Internet use and patient behaviors,” said principal investigator and public health professor Sarah Bass, Ph.D. “We wanted to see
A team of researchers from the National Center for Atmospheric Research (NCAR) and other institutions is heading to Mexico City to participate in one of the most complex field campaigns ever undertaken in atmospheric chemistry. From March 1 to 29, the team will make multiple research flights in the NSF/NCAR C-130 aircraft and operate ground instruments to investigate the chemical and physical transformation of air pollution as it flows downwind from Mexico City.
