WASHINGTON – Approximately one million Americans suffer a heart attack each year of which some 400,000 attacks are fatal. A key cause of heart attacks is atherosclerosis, a process in which cholesterol builds up in the arteries and impedes the ability of the blood to flow to our most vital organ. Atherosclerosis is often associated with a high-fat diet in humans, but in a new study using an animal model researchers have found that a high-fat diet for a very short period can protect the heart from heart attacks and result in less tissue damage when heart attacks occur. ...

WASHINGTON – Walking on a treadmill for one hour a day may slow the progression of nonalcoholic fatty liver disease in obese people with prediabetes by jump-starting their metabolism and slowing the oxidative damage wrought by the condition, say researchers at the Cleveland Clinic. A study of 15 obese people with nonalcoholic fatty liver disease revealed that the daily walks not only increase insulin sensitivity, but improve the liver's polyunsaturated lipid index (PUI), which is thought to be a marker of liver health. The improvements are linked to an increase in the ...

CINCINNATI—A new study from researchers at the University of Cincinnati (UC) shows that short-term, high-fat "splurges" within one's diet could elicit cardioprotective properties during a heart attack. These findings are being presented for the first time at the 2011 Experimental Biology Meeting sponsored by the American Society for Pharmacology and Experimental Therapeutics on April 13 in Washington, D.C. Lauren Haar, a doctoral student in the Systems Biology and Physiology Graduate Program, found that short-term, high-fat feeding in animal models led to cardioprotection ...

GRAND RAPIDS, MICH., April 13, 2011 – Although only one in 10 American adults eats enough fruits and vegetables (1), new research being presented at the Experimental Biology meeting this week in Washington, D.C., finds older adults are consuming higher levels of carotenoids, flavonoids and other phytonutrients found in fruits and vegetables that are thought to support healthy aging. Specifically, the new findings suggest that, calorie for calorie, intakes of carotenoids are 20 percent higher, flavonoids 40 percent higher, and ellagic acid is 80 percent higher among older ...

ROCHESTER, Minn. -- A new research study of the effect of a commonly used strategy to reduce the spread of antibiotic-resistant bacteria in hospital intensive care units (ICU) shows that the strategy had no significant effect. That's the surprising finding of a multisite study led by Mayo Clinic investigators. The bacteria -- methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococcus (VRE) -- are resistant to common antibiotics and harder to treat if patients become infected. The findings appear in today's New England Journal of Medicine (http://www.nejm.org/). The ...

A team of scientists at Penn State University, the Salk Institute for Biological Studies, and other institutions have developed a method for recreating a schizophrenic patient's own brain cells, which then can be studied safely and effectively in a Petri dish. The method brings researchers a step closer to understanding the biological underpinnings of schizophrenia. The method also is expected to be used to study other mysterious diseases such as autism and bipolar disorder, and the researchers hope that it will open the door to personalized medicine -- customized treatments ...

LA JOLLA, CA- After a century of studying the causes of schizophrenia-the most persistent disabling condition among adults-the cause of the disorder remains unknown. Now induced pluripotent stem cells (iPSCs) generated from schizophrenic patients have brought researchers from the Salk Institute for Biological Studies a step closer to a fundamental understanding of the biological underpinnings of the disease. In their study, published in the April 13, 2011 advance online issue of the journal Nature, the Salk team reports both that neurons generated from these patient-derived ...

A new MRI device that guides surgeons as they implant electrodes into the brains of people with Parkinson's disease and other neurological disorders could change the way this surgery, called deep brain stimulation, is performed at medical centers across the country, according to a group of doctors at University of California, San Francisco. Deep brain stimulation can help to alleviate patients' symptoms, and the new device will make the procedure faster and more comfortable for the patient. It grew out of a home-grown technique developed by a team of UCSF neurosurgeons ...

NGC 3582 is part of a large star-forming region in the Milky Way, called RCW 57. It lies close to the central plane of the Milky Way in the southern constellation of Carina (The Keel of Jason's ship, the Argo). John Herschel first saw this complex region of glowing gas and dark dust clouds in 1834, during his stay in South Africa. Some of the stars forming in regions like NGC 3582 are much heavier than the Sun. These monster stars emit energy at prodigious rates and have very short lives that end in explosions as supernovae. The material ejected from these dramatic events ...

Paleontologists from the American Museum of Natural History and the Chinese Academy of Sciences announce the discovery of Liaoconodon hui, a complete fossil mammal from the Mesozoic found in China that includes the long-sought transitional middle ear. The specimen shows the bones associated with hearing in mammals— the malleus, incus, and ectotympanic— decoupled from the lower jaw, as had been predicted, but were held in place by an ossified cartilage that rested in a groove on the lower jaw. The new research, published in Nature this week, also suggests that the middle ...

Free bingo site City Bingo has stepped up its devotion to providing its players with an array of weekend special and promotions. The metropolitan bingo site already offers 70% bonuses on Saturdays and 80% bonuses on Sundays and has now added The Bingo Avenue Tournament. Players depositing at weekends had already been enjoying the aforementioned bonuses on their deposits and the introduction of their latest game is likely to keep the site buzzing. The new feature involves players picking numbers that they don't think will come up in a draw, they can swap any points accrued ...

Infectious disease is a huge cause of death globally, and is a particular threat to newborns whose immune systems respond poorly to most vaccines. A new approach developed at Children's Hospital Boston, using an adjuvant (an agent to stimulate the immune system) along with the vaccine, shows promise in a study of blood from Gambian infants. Results will appear in the open-access journal PLoS ONE on April 13. The ability to immunize newborns would close their window of vulnerability to serious infections during the first months of life, such as respiratory syncytial ...

If you have been diagnosed with breast cancer that requires surgery, the time to consider reconstruction options is now, even before you schedule your mastectomy or lumpectomy. Because the type of mastectomy procedure you receive can have a significant impact on your reconstruction options, failing to consider your options early can limit them later. Getting breast reconstruction is optional, it is not required, and some women find that life without breasts is freeing. However, if you would prefer to maintain your feminine appearance, breast reconstruction is a far ...

The moments immediately following a serious auto accident can be overwhelming and scary, especially if someone suffers serious personal injury or death. Oftentimes, people are in a state of shock and not thinking clearly following a horrific car accident, but the moments immediately following the accident are critical to the outcome of a personal injury claim that may be filed later. For this reason, even though you will be overwhelmed and frightened, it is important that you take certain steps after a car accident and never admit fault at the scene of the accident ...

Some 2.6 million third trimester stillbirths worldwide occur every year, according to the first comprehensive set of stillbirth estimates, published today within a special series in the medical journal The Lancet. Every day more than 7,300 babies are stillborn. A death occurs just when parents expect to welcome a new life. Ninety-eight percent of stillbirths occur in low and middle-income countries. Wealthier nations are not immune with 1 in 200 pregnancies resulting in a stillbirth - two thirds occurring in the last trimester of pregnancy, a rate that has stagnated ...

Parenting time and child custody are necessary considerations in divorce agreements where children are involved. This is a particularly difficult process and can result in lengthy legal battles. Ultimately, the courts will determine what is in the best interest of the child. This may require expert testimony from a Child and Family Investigator appointed by the court, or from friends and relatives of the parents and children. Considerations in Custody Battles The court will consider several factors when determining the best interest of a child. This can include things ...

Remote lochs along the west coast of Scotland are turning up new evidence about the origins of life on land. A team of scientists exploring rocks around Loch Torridon have discovered the remarkably preserved remains of organisms that once lived on the bottom of ancient lake beds as long as a billion (1000 million) years ago. These fossils illuminate a key moment in the history of evolution when life made the leap from tiny, simple bacterial (prokaryote) cells towards larger, more complex (eukaryotic) cells which would make photosynthesis and sexual reproduction possible. The ...

Researchers at the Johns Hopkins Bloomberg School of Public Health have developed a non-steroid based strategy for improving the lung's innate immune defense and decreasing inflammation that can be a problem for patients with chronic obstructive pulmonary disease (COPD). In a study published in the April 13 edition of the journal Science Translational Medicine, the Johns Hopkins researchers targeted the Nrf2 pathway using sulforaphane, an ingredient that is present in broccoli in a precursor form, to enhance the Nrf2 pathway in the lung that mediates the uptake of bacteria. ...

California's temperate climate, long stretches of highway and sunny days make it a motorcyclist's dream. Riders can take to the streets all year long, feeling the wind in their hair and enjoying the freedom that can only be felt on a bike. Of course, as gas prices and temperatures continue to climb, more and more motorcycles will be on the road. Before summer riding season gets in full swing, though, it is important for California motorcyclists to know the rules of the road, including two laws unique to motorcycles. What Is Different for Motorcycles Versus Passenger ...

BUFFALO, N.Y. -- A just released study on the relationship between multiple sclerosis (MS) and chronic cerebral venous insufficiency (CCSVI), a narrowing of the extracranial veins that restricts the normal outflow of blood from the brain, found that CCSVI may be a result of MS, not a cause. The study, conducted by University at Buffalo researchers, appears in the current issue of Neurology, the journal of the American Academy of Neurology. Robert Zivadinov, MD, PhD, associate professor of neurology in the UB School of Medicine and Biomedical Sciences and president of ...

Today, there is increasing exposure of individuals to a public audience. Television shows and the internet provide platforms for this and, at times, allow observing others' flaws and norm transgressions. Regardless of whether the person observed realizes their flaw or not, observers in the audience experience vicarious embarrassment. For the first time, such vicarious embarrassment experiences as well as their neural basis have been investigated in research published in the open-access, peer-reviewed journal PLoS ONE. The research was led by Sören Krach and Frieder M. ...

What's the difference between stealing a CD from a music store and ripping off music online? The music industry and law enforcers say that there is none: Theft is theft, whether it's physical or digital. College students participating in a newly published study, however, said that while they were unlikely to shoplift and viewed that behavior as immoral, they were not exactly motivated to follow the laws governing digital music piracy -- a finding that underscores the difficulties of enforcing such laws and to find new ways to discourage the theft of all types of digital ...
