Public release date: 15-Jan-2008 Probiotics, such as yoghurt drinks containing live bacteria, have a tangible effect on the metabolism, according to the results of a new study published today (Tuesday 15 January) in the journal Molecular Systems Biology. The research is the first to look in detail at how probiotics change the biochemistry of bugs known as gut microbes, which live in the gut and which play an important part in a person’s metabolic makeup. Different people have different types of gut microbes inside them and abnormalities in some types have recently been linked to diseases such as diabetes and […]
Public release date: 15-Jan-2008 A University of British Columbia and Vancouver Coastal Health Research Institute study has found that a popular class of osteoporosis drugs nearly triples the risk of developing bone necrosis, a condition that can lead to disfigurement and incapacitating pain The research is the largest study of bone necrosis and bisphosphonates, a class of drugs used by millions of women worldwide to help prevent bone fractures due to osteoporosis. It is also the first study to explore the link between bone necrosis and specific brands of bisphosphonates, such as Actonel, Didrocal and Fosamax. Researchers found that all […]
Public release date: 16-Jan-2008 ST. PAUL, Minn. – Contrary to some reports, taking statins, which are cholesterol-lowering drugs, offers no protection against Alzheimer’s disease, according to research published in the January 16, 2008, online issue of Neurology®, the medical journal of the American Academy of Neurology. “Some studies have suggested people taking cholesterol-lowering drugs are less likely to have Alzheimer’s disease, but our longitudinal findings found no relation between statin use and Alzheimer’s,” said study author Zoe Arvanitakis, MD, MS, Associate Professor of the Department of Neurological Sciences at Rush University Medical Center in Chicago and member of the […]
Public release date: 16-Jan-2008 PORTLAND, Ore. – Selective publication in reporting results of antidepressant trials exaggerates the effectiveness of the drugs, according to a report in the January 17 issue of the New England Journal of Medicine. The report’s primary author is Erick Turner, M.D., assistant professor of psychiatry, physiology and phamacology at Oregon Health & Science University (OHSU) and Medical Director of the Portland Veterans Affairs Medical Center’s Mood Disorders Program. Turner and his colleagues examined reviews from the Food and Drug Administration (FDA) for trials of 12 widely prescribed antidepressant drugs approved between 1981 and 2004, involving […]
Public release date: 16-Jan-2008 Liver cancer is the fifth most common cancer in the world with a poor prognosis. About three quarters of the cases of liver cancer are found in Southeast Asia, including China, Hong Kong, Taiwan, Korea, India, and Japan. The frequency of liver cancer in Southeast Asia and sub-Saharan Africa is greater than 20 cases per 100,000 population. Moreover, recent data show the frequency of liver cancer in the U.S. overall is rising. With the increasing trend in the incidence of cancers in our country, biomedical research directed at early detection and diagnosis, prognosis and […]
Public release date: 16-Jan-2008 Many hepatocellular carcinoma (HCC) patients in China may be treated with Traditional Chinese medicine (TCM). Some say it works, others doubt its effectiveness. These stated that a research group in China had found TCM can down-regulate the expression of PTEN in HCC, which may suppress tumor cell growth and regulate tumor cell invasion and metastasis. A research article published on January 7, 2008 in the World Journal of Gastroenterology (volume 14, issue 1) addresses this problem. The research group imbedded hepatoma carcinoma tissue in the livers of 48 male athymic mice. The mice were distributed randomly […]
Public release date: 16-Jan-2008 Quebec City, January 16, 2008—A research team from Université Laval’s Faculty of Medicine and Robert-Giffard Hospital has demonstrated that weight gain induced by the use of antipsychotic drugs—which in extreme cases can be as high as 30 kilos in only one month—can be avoided through a specially designed weight control program. The researchers supervised by psychiatrist Marie-Josée Poulin and kinesiologist Angelo Tremblay report the details of their findings in a recent edition of the Australian and New Zealand Journal of Psychiatry. To evaluate the program’s effectiveness, the research team regularly measured the participants’ key biochemical […]
Public release date: 16-Jan-2008 Findings from what is believed to be the largest comparison of blood samples collected from healthy individuals and people with schizophrenia suggest that infection with the common Toxoplasma gondii parasite, carried by cats and farm animals, may increase the risk of schizophrenia. A report on the study, conducted among U.S. military personnel by researchers from Walter Reed Army Institute of Research and Johns Hopkins Children’s Center appears in the January issue of the American Journal of Psychiatry. Researchers found that of the 180 study subjects diagnosed with schizophrenia, 7 percent had been infected […]
Public release date: 17-Jan-2008 PITTSBURGH, Jan. 17 – A new strategy to hunt for human viruses described in this week’s issue of the journal Science by the husband-and-wife team who found the cause of Kaposi’s sarcoma has revealed a previously unknown virus strongly associated with another rare but deadly skin cancer called Merkel cell carcinoma. In the paper, University of Pittsburgh Cancer Institute (UPCI) researchers, Huichen Feng, Ph.D., Masahiro Shuda, Ph.D., Yuan Chang, M.D., and Patrick Moore, M.D., M.P.H., explain a nearly decade-long effort to harness the sequencing technology to identify the virus, which they call Merkel cell polyomavirus (MCV). […]
Public release date: 17-Jan-2008 Drugs for pre-osteoporosis: Prevention or disease-mongering? A series of recent scientific publications have exaggerated the benefits and underplayed the harms of drugs to treat pre-osteoporosis or “osteopenia” potentially encouraging treatment in millions of low risk women, warn experts in this week’s BMJ. The authors believe that this represents a classic case of disease-mongering: a risk factor being transformed into a medical disease in order to sell tests and drugs to relatively healthy people. Osteopenia or “pre-osteoporosis” is said to affect around half of all older women and, in at least one country, drug companies have […]
Public release date: 21-Jan-2008 A saline nasal wash solution made from processed seawater appears to improve nasal symptoms and may help prevent the recurrence of respiratory infections when used by children with the common cold, according to a report in the January issue of Archives of Otolaryngology, one of the JAMA/Archives journals. Ivo Šlapak, M.D., of Teaching Hospital Brno, Brno, Czech Republic, and colleagues randomly assigned 401 children age 6 to 10 with cold or flu to two treatment groups, one receiving standard medication and the other also receiving a nasal wash with a modified processed seawater solution. “Patients were […]

Public release date: 26-Dec-2007 Modified protein developed by UC-San Diego researchers may lead to first cure for cirrhosis of the liver University of California, San Diego researchers have proven in animal studies that fibrosis in the liver can be not only stopped, but reversed. Their discovery, to be published in PLoS Online on December 26, opens the door to treating and curing conditions that lead to excessive tissue scarring such as viral hepatitis, fatty liver disease, cirrhosis, pulmonary fibrosis, scleroderma and burns. Six years ago, the UC San Diego School of Medicine research team discovered the cause of the excess […]
Public release date: 1-Jan-2008 The dietary supplement L-carnitine can lessen fatigue and boost mental function in very old people, Italian researchers report. Study participants given L-carnitine also experienced significant increases in muscle mass and reductions in fat mass, Dr. Mariano Malaguarnera and colleagues from the University of Catania report in the December issue of the American Journal of Clinical nutrition. L-carnitine helps cells to produce energy from fat. The highest concentrations of the molecule are found in parts of the body with high energy demands, such as the skeletal muscles and the heart. Overall concentrations of L-carnitine decline after […]
Public release date: 1-Jan-2008 Early exposure to environmental toxins can lead to diseases much later in life. This week, Wu et al. report that primates exposed to lead as infants showed Alzheimer’s disease (AD)-like pathology years later. From birth to 400 d of age, monkeys were exposed to lead levels that produced no obvious sign of toxicity. Although by young adulthood blood lead levels in exposed monkeys were indistinguishable from those of controls, when examined at approximately 23 years of age, the brains of lead-exposed monkeys exhibited many hallmarks of AD, including Aâ plaques and neurofibrillary tangles, as […]
Public release date: 1-Jan-2008 Phantom noises, that mimic ringing in the ears associated with tinnitus, can be experienced by people with normal hearing in quiet situations, according to new research published in the January 2008 edition of Otolaryngology – Head and Neck Surgery. The Brazilian study, which consisted of 66 people with normal hearing and no tinnitus, found that among subjects placed in a quiet environment where they were asked to focus on their hearing senses, 68 percent experienced phantom ringing noises similar to that of tinnitus. This is compared to only 45.5 percent of participants who heard phantom ringing […]
Public release date: 2-Jan-2008 Just as additives help gasoline burn cleaner, a research report published in the January 2008 print issue of The FASEB Journal shows that the food industry could take a similar approach toward reducing health risks associated with fatty foods. These “meal additives” would be based on work of Israeli researchers who discovered that consuming polyphenols (natural compounds in red wine, fruits, and vegetables) simultaneously with high-fat foods may reduce health risks associated with these foods. “We suggest a new hypothesis to explain polyphenols,” said Joseph Kanner, senior author of the report. “For the first time, these […]
Public release date: 2-Jan-2008 In the late 1950s, the late Democratic Senator Estes Kefauver, Chairman of the United States Senate’s Anti-Trust and Monopoly Subcommittee, put together the first extensive indictment against the business workings of the pharmaceutical industry. He laid three charges at the door of the industry: (1) Patents sustained predatory prices and excessive margins; (2) Costs and prices were extravagantly increased by large expenditures in marketing; and (3) Most of the industry’s new products were no more effective than established drugs on the market [1]. Kefauver’s indictment against a marketing-driven industry created a representation of the pharmaceutical […]
Public release date: 2-Jan-2008 Tips to prevent adverse drug events in older adults BOSTON (January 2, 2008) Adverse drug events are more common in older adults because they are prescribed more drugs and are effected differently by these drugs than their younger counterparts. A review article written by Tufts University School of Medicine clinicians, published in American Family Physician, summarizes steps that physicians and other healthcare providers can take to avoid overuse, misuse, and underuse of medication in older adults. “About one in three older persons taking at least five medications will experience an adverse drug event each year, and […]
Public release date: 2-Jan-2008 Boston, MA— Researchers from Boston University School of Medicine (BUSM) have found that vitamin D2 is equally as effective as vitamin D3 in maintaining 25-hydroxyvitamin D status. The study appears online in the December 2007 issue of the Journal of Clinical Endocrinology & Metabolism. Researchers studied healthy adults aged 18-84 who received either placebo, 1,000 International Units (IU) of vitamin D3, 1,000 IU of vitamin D2, or 500 IU of vitamin D2 plus 500 IU of vitamin D3 daily for three months at the end of winter to establish what effect it had on circulating levels […]
