New system could replace time-intensive, century-old lab techniques
For the millions of people who suffer from urinary tract infections each year and the doctors who treat them, a promising new biosensor technology has been developed that may replace antiquated testing methods and save precious health care dollars.
In a recent clinical study conducted by the David Geffen School of Medicine at UCLA and the Veterans Affairs Greater Los Angeles Healthcare System, resear
Revolution in progress: U-M study shows a wide range of problems in body’s largest artery can be treated with a minimally invasive procedure
Tens of thousands of Americans live with a ticking time bomb in their chests. Now, a new University of Michigan study demonstrates that many of them may not need surgery in order to defuse it.
Instead, the research shows, a minimally-invasive procedure can repair a wide range of problems in the upper part of the aorta, the g
The pesticide brew in many ponds bordering Midwestern cornfields is not only affecting the sexual development of frogs, but is making them more prone to deadly bacterial meningitis, according to a new study by University of California, Berkeley, scientists.
These physiological effects combine with environmental disruptions to make the life of a frog seem like something out of a horror movie and are likely among the factors causing a decline in amphibian populations worldwide, the
Atherosclerosis, an accumulation of fat and inflammation in arteries, causes myocardial infarction and stroke, two deadly complications. The risk factors for atherosclerosis are well known and include hypercholesterolemia, smoking, diabetes and high blood pressure. Protective factors may also be important in atherosclerosis but are poorly understood. A new study published in this month´s issue of Nature Medicine presents the discovery of such a protective mechanism, which could be of great im
If you were asked what station is currently orbiting 400 km above the Earth at 28 000 km/h you may be tempted to answer the International Space Station (ISS). This is of course correct but if you were to look with a good telescope behind the ISS (or tune in with the appropriate equipment) you may soon pick up a second station: a radio station.
On Friday 3 February, at 23:20 Central European Time the ISS Crew of Valery Tokarev and William McArthur are due to start an EVA from t
Agri-environment schemes (AES) in Europe appear to be largely ineffective as policy instruments. Research in five European countries has shown that common species of birds, insects and plants do not benefit very much from this kind of nature management and rare species benefit much less. There are virtually no benefits for threatened species (listed in the Red Data Books). These conclusions were drawn by researchers from six European research institutions during a conference on 30 and 31 January at
“Face to Face”, a DVD Rom demonstrating psychiatric interviewing and electro convulsive treatment, has been launched at the Keele University Undergraduate Medical School. This new teaching resource is intended for medical students and is useful to all mental health students, irrespective of discipline.
The interviews, which are accompanied by annotations and highlight key questions or symptoms, cover a range of conditions, including Schizophrenia, eating disorder, school refusal, somatof
The government’s new white paper on health seems to suggest that patients should be offered more choice. However, visiting the doctor or phoning the police is simply not like shopping, according to people questioned for a new study funded by the Economic and Social Research Council (ESRC), which found that most of us reject the trend towards treating everyone as ‘consumers’.
We see public services as different from the market-place and value their ‘publicness’, according to the project le
A new sleeping pill that increases dreaming sleep improves memory capacity, according to the results of new research.
With only 10% of the 20-30% of the population who suffer with insomnia taking medication, pharmaceutical companies have been searching for the perfect sleeping pill. And one company at least has developed a completely new type of drug that not only induces sleep, but also increases the dream phase, consolidating memory and improving one’s sense of wellbeing.
A new screening technique for methicillin-resistant Staphylococcus aureus (MRSA) cuts by 75% the time taken to identify patients carrying MRSA and could be used to help prevent transmission of the bacteria in hospitals. A study published today in the journal Critical Care shows that a new molecular screening test for MRSA decreases the time between screening and notification of results from four days to one day, compared with standard screening methods. The new method also prevents patients from
Several new dyes have been identified as candidates to stain the internal limiting membrane (ILM) as well as other tissues of the eye that need to be removed…
The invention offers a novel class of Tryptanthrin-derivatives and a method for preparing the derivatives. These compounds shall be useful as drugs for the…
Scientists have demonstrated the first reproducible, controllable silicon transistors that are turned on and off by the motion of individual electrons. The experimental devices, designed and fabricated at NTT Corp. of Japan and tested at NIST, may have applications in low-power nanoelectronics, particularly as next-generation integrated circuits for logic operations (as opposed to simpler memory tasks).
The transistors, described in the Jan. 30, 2006, issue of Applied Physics Lette
Fire panels, or “annunciators,” are electronic devices that display data on building conditions in one easily accessible location. When used by first responders during emergencies, the devices can save lives. In December 2005, the National Electrical Manufacturing Association (NEMA) released a comprehensive standard* that promises to make future annunciators even more useful decision-making tools to fire fighters at the scene, to commanders back at headquarters, or to building and emergency pers
A rubbery material that can purify hydrogen efficiently in its most usable form for fuel cells and oil refining has been developed by a chemical engineering group at The University of Texas at Austin.
In the Feb. 3 edition of Science, Dr. Benny Freeman details how his laboratory designed the membrane material and tested its ability, with colleagues at Research Triangle Institute (RTI) in Research Triangle Park, N.C., to successfully separate hydrogen from carbon dioxide and other
Findings help researchers revise models of mammalian sense of smell
In a mouse model, University of Pennsylvania School of Medicine researchers discovered that olfactory sensory neurons expressing the same receptor responded to a specific odor with an array of speeds and sensitivities, a phenomenon previously not detected in the mammalian sense of smell. The group published their findings this week in the online edition of the Proceedings of the National Academy of Sciences.
