Findings offer new ideas on disease states
New research from University of North Carolina at Chapel Hill shows how a protein may be crucial to the regulation of genes in embryonic stem cells. The protein, called “eed,” is needed for an essential chemical modification of many genes. Embryos cannot survive without the modification.
The findings appear in the May 24 issue of the journal Current Biology.
The research offers an important contribution to a new wave
Fibrosis (scar tissue formation) is the determinant lesion in the subsequent evolution of the heart in a patient with high blood pressure. This item appeared in the latest edition of Nature Clinical Practice Cardiovascular Medicine, a journal that is part of the Nature group. The article published heart research recently carried out at the University of Navarra.
When arterial blood pressure rises, we have what is known as high blood pressure and the heart becomes overloaded,
The value of property is linked more closely to income and ability to pay tax than many people think, according to new research sponsored by the ESRC.
With council tax still a hot issue, a study led by Dr Michael Orton, of the University of Warwick, found that the problem of people on low incomes living in high value properties may also be less common than often assumed.
Dr. Orton said: “We found that for owner-occupiers there is overall a clear and positive relationsh
Patients approaching the end of life can significantly reduce their depression symptoms and improve their sense of spiritual well-being according to a study published in the current issue of the Journal of Palliative Medicine.
“Patients with serious medical conditions frequently suffer psychological, relational, and spiritual distress that is being inadequately addressed by modern health care,” writes first author Douglas Miller, M.D., Indiana University School of Medicine pr
What if the speed of light is a constant only most of the time? What if gravity sometimes pushed instead of pulled? Scientists are increasingly asking what would seem like far-out questions regarding the laws and rules of physics after discovering conditions and materials where the rules don’t quite apply. Take the Doppler effect.
The Doppler effect is in use everywhere, everyday. Police use it to catch speeders. Satellites use it to track space debris and air-traffic control
Patients disfigured in traumatic incidents are much more likely to suffer post traumatic stress disorder, unemployment, marital problems, binge drinking and depression, according to a study by Yale School of Medicine researchers.
Although the study included only 20 subjects, the findings are significant and address an issue that has not been widely studied, said the senior author, John Persing, M.D., professor and section chief of plastic surgery in the Department of Surgery.
Scientists for the first time have watched agents of brain-wasting diseases, called transmissible spongiform encephalopathies (TSE), as they invade a nerve cell and then travel along wire-like circuits to points of contact with other cells. These findings will help scientists better understand TSE diseases and may lead to ways to prevent or minimize their effects. TSE, or prion, diseases include scrapie in sheep and goats; chronic wasting disease in deer and elk; mad cow disease in cattle; a
Patients who had received livers from hepatitis B virus core antibody (HBcAb) positive (indicates prior exposure to hepatitis B) and/or hepatitis C virus (HCV) positive donors had similar graft and patient survival compared to patients who received HBcAb negative or HCV negative livers, according to a study by the University of Pittsburgh’s Thomas E. Starzl Transplantation Institute. The results of their findings are being presented today at sixth annual American Transplant Congress, the joint
More than half of people with asthma report that their symptoms are brought on by laughter, according to a study to be presented at the American Thoracic Society International Conference on May 24.
The study of 235 patients with asthma found that 56% had laughter-induced asthma (LIA). Asthma that is triggered by laughter doesn’t seem to cause more asthma flare-ups requiring emergency room visits or hospitalizations compared with other types of asthma, according to study
Measuring a hormone in the blood can help doctors greatly reduce the number of days pneumonia patients have to take antibiotics to cure their infection, according to a study to be presented at the American Thoracic Society International Conference on May 24.
In the study, pneumonia patients whose level of the hormone procalcitonin was measured during the course of their illness took antibiotics an average of 6 days, compared with 12 days for patients whose procalcitonin levels
Female lung transplant recipients are significantly more likely to suffer from a type of injury to the transplanted lung called primary graft dysfunction than male lung transplant patients, according to a study to be presented at the American Thoracic Society International Conference on May 24.
The study found that female lung transplant recipients who received a lung from either a male or female donor were almost 60% more likely to suffer from primary graft dysfunction, compa
The idea that your bladder shrinks as you get older may be nothing more than an old wives’ tale according to a University of Pittsburgh study. The feeling may, however, signal a treatable underlying condition. Results are to be presented today at the annual meeting of the American Urological Association (AUA) in San Antonio, and will be published in abstract 1218 in the AUA proceedings.
“Many of us, after reaching a certain age, notice that we have to urinate more frequentl
Women with breast cancer who engaged in an amount of physical activity equivalent to walking 1 or more hours per week had better survival compared with those who exercised less than that or not at all, according to a study in the May 25 issue of JAMA.
There is reason to believe that physical activity might extend survival in women with breast cancer, according to background information in the article. Physical activity has been linked to lower levels of circulating ovarian ho
European entrepreneurs, small businesses, academia and research institutes have the chance to win business development support worth €50 000 if they come up with the best idea for an innovative use of Galileo, Europe’s coming global navigation satellite system.
The Galileo Masters 2005 competition, which has ESA’s European Space Incubator as one of its sponsors, is being run under the patronage of the Bavarian Minister for Economic Affairs, Dr Otto Wiesheu. Its aim is to enc
The accession to the European Union (EU) ten years ago was for the Finnish agriculture and food sector an unprecedented rapid shift from closed and regulated markets to open and more competitive ones. Finnish farmers faced a change in output prices, relative prices and direct support which were of exceptional magnitude compared to that of any other country which had ever joined the EU. Commitment to the Common Agricultural Policy (CAP) lowered the producer price level in Finland by 40-50% ri
Penn State College of Medicine study shows for the first time in an animal model that ceramide, a naturally occurring substance that prevents the growth of cells, can be administered through the blood stream to target and kill cancer cells.
“Ceramide is the substance that accumulates in cancer tissues and helps to kill cancer cells when patients undergo chemotherapy and radiation,” said Mark Kester, Ph.D., professor of pharmacology, Penn State College of Medicine, Penn State Mil
