Public release date: 11-Feb-2008 The cancer drug Avastin (bevacizumab) is used to treat advanced bowel cancer in combination with chemotherapy. This drug targets a protein called VEGF (vascular endothelial growth factor) that stimulates blood vessel growth. Avastin inhibits the growth of tumors by cutting off their blood supply, which deprives them of oxygen and other nutrients. In a small percentage of patients, however, Avastin can cause neurological side effects ranging from headaches and blurry vision to potentially fatal seizures and brain swelling. The new study reveals that VEGF normally protects the specialized cells that create a seal […]
Public release date: 11-Feb-2008 Boston (Feb. 11, 2008) — Research conducted by Massachusetts Eye and Ear Infirmary (MEEI) Cornea Service Director and Harvard Medical School Professor Reza Dana, M.D., M. Sc., MPH, and colleagues at the Schepens Eye Research Institute have found for the first time that topical drop application of alpha-linolenic acid (ALA) led to a significant decrease in clinical signs of dry eye syndrome (DES) in animal models. ALA is a fatty acid that cannot be made by the body and must be supplied in the diet. The study will be published in the February 2008 […]
Public release date: 11-Feb-2008 Journal of Agricultural and Food Chemistry Scientists in Arkansas are reporting new evidence that natural pigments responsible for the beautiful blue/purple/reddish color of certain fruits and vegetables may help prevent obesity. Their animal study, scheduled for the Feb. 13 issue of ACS’ Journal of Agricultural and Food Chemistry, however, reports that eating the whole fruit containing these pigments seems to be less effective than eating an extract of the berry. Ronald L. Prior and colleagues, who did the new study, note that past research has shown that the pigments — called anthocyanins — prevent obesity in […]
Public release date: 11-Feb-2008 Study finds evidence of fake malaria drugs being manufactured in China A unique collaborative study between scientists, public health workers and police has led to the arrest of alleged traders of fake anti-malarial drugs in China. The epidemiological investigation, involving teams from across the globe and published in this week’s PLoS Medicine, highlights the growing threat posed by fake pharmaceuticals and the complexities of tracking down those responsible for their manufacture. Fake anti-malarial drugs are an increasingly serious problem, particularly in South East Asia and Africa. In countries such as Myanmar (Burma), the Lao PDR, […]
Public release date: 11-Feb-2008 Autopsies of individuals in one Minnesota County suggest that the decades-long decline in the rate of coronary artery disease may have ended and possibly reversed after 2000, according to a report in the February 11 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. “Over the past century, the rate of death due to heart disease in the United States rose until the mid 1960s when it began a steady decline, which continues today,” the authors write as background information in the article. These declines appear to be accompanied by reductions in the […]
Public release date: 11-Feb-2008 Complex fibroadenomas have a low incidence of malignancy, so women with this condition can be more conservatively treated and avoid surgical biopsy, according to a new study by a team of researchers from the Hadassah-Hebrew University Medical Center in Jerusalem. A fibroadenoma is a benign growth of the breast that is common in young women. They are not usually associated with breast cancer, and are often diagnosed with simple ultrasound-guided, non-surgical biopsy. Complex fibroadenomas are a subtype of fibroadenomas. They are also benign, but they have calcifications and small cysts that make their pathology […]
Public release date: 11-Feb-2008 SACRAMENTO, Calif.) – New research from the UC Davis M.I.N.D. Institute and Center for Children’s Environmental Health has found that antibodies in the blood of mothers of children with autism bind to fetal brain cells, potentially interrupting healthy brain development. The study authors also found that the reaction was most common in mothers of children with the regressive form of autism, which occurs when a period of typical development is followed by loss of social and/or language skills. The findings, to be published in the March 2008 issue of Neurotoxicology, raise the possibility that the transfer […]
Public release date: 13-Feb-2008 A research group of the University of Granada has found out that maslinic acid, a compound present in the leaf and the olive skin wax extracted from alpeorujo (crushed olive pulp), has the capacity of preventing cancer as well as regulating apoptosis in carcinogenic processes. Maslinic acid is a protease inhibitor that, among other features, has the capacity of regulating cell growth. It is useful for cancer treatment, as it allows to control the hyperplasia and hypertrophy processes, typical of this disease. The scientists of the UGR have characterized for the first time maslinic acid action […]
Public release date: 13-Feb-2008 University of Illinois study shows that exercise-trained mice get far fewer gallstones than sedentary mice and identifies potential mechanisms to explain why this occurs. The study, recently published in the Journal of Applied Physiology, can be viewed online at: http://jap.physiology.org/cgi/reprint/01292.2007v1. “For the first time, we have direct evidence that physical activity reduces gallstone formation, adding to the ever-increasing number of reasons that people should get more exercise,?said Kenneth Wilund, a faculty member in the U of I Division of Nutritional Sciences and an Assistant Professor in Kinesiology and Community Health. Gallbladder disease affects 10 to […]
Public release date: 14-Feb-2008 Researchers from the University of Chicago have discovered that many of the genetic variations that have enabled human populations to tolerate colder climates may also affect their susceptibility to metabolic syndrome, a cluster of related abnormalities such as obesity, elevated cholesterol levels, heart disease, and diabetes. More than 100 years ago, scientists noted that humans inhabiting colder regions were bulkier and had relatively shorter arms and legs. In the 1950s, researchers found correlations between colder climates and increased body mass index (BMI), a measure of body fat, based on height and weight. Now, in a study […]
Public release date: 14-Feb-2008 An Israeli scientist, Dr. Siegal Sadetzki, has found a link between cell phone usage and the development of tumors. Dr. Sadetzki, a physician, epidemiologist and lecturer at Tel Aviv University, published the results of a study recently in the American Journal of Epidemiology, in which she and her colleagues found that heavy cell phone users were subject to a higher risk of benign and malignant tumors of the salivary gland. Those who used a cell phone heavily on the side of the head where the tumor developed were found to have an increased risk […]
Public release date: 16-Feb-2008 In his research, scientist Nat Scholz examines how pesticides that run off the land and mix in rivers and streams combine to have a greater than expected toxic effect on the salmon nervous system. These pesticides are widely used in the United States and their occurrence as mixtures in the food supply for humans may also pose an unexpected risk for people. “We have a pretty good handle on how to assess the health effects of single chemicals in conventional toxicity trials,” said Scholz, a fishery biologist with the National Oceanic and Atmospheric Administration. “But the […]
Public release date: 18-Feb-2008 A sense of hopefulness does not improve as quickly as other symptoms ANN ARBOR, Mich. — People taking medication for depression typically see a lot of improvements in their symptoms during the first few months, but lagging behind other areas is a sense of hopefulness, according to new research from the University of Michigan Health System. That means people with depression may still feel a sense of hopelessness even while their condition is improving, which could lead them to stop taking the medication. For many in the study, feelings of hopefulness did not improve […]
Public release date: 18-Feb-2008 ATLANTA – The flu season is getting worse, and U.S. health officials say it’s partly because the flu vaccine doesn’t protect against most of the spreading flu bugs. The flu shot is a good match for only about 40 percent of this year’s flu viruses, officials at the U.S. Centers for Disease Control and Prevention said Friday. That’s worse than last week’s report when the CDC said the vaccine was protective against roughly half the circulating strains. In good years, the vaccine can fend off 70 to 90 percent. Infections from an unexpected strain have […]
Public release date: 18-Feb-2008 WASHINGTON – GlaxoSmithKline Plc’s rotavirus vaccine is associated with increased pneumonia-related deaths and other adverse reactions, U.S. regulatory staff said in documents posted on Friday. The review comes ahead of a Food and Drug Administration advisory meeting next Wednesday to consider approval of the oral vaccine to prevent the most common cause of severe diarrhea and dehydration among infants and young children in the world. FDA staff said its analysis of 11 studies revealed that in the largest trial, there was a statistically significant increase in deaths related to pneumonia compared with placebo, documents posted […]

Public release date: 22-Jan-2008 Over-the-counter medicine is commonly and casually used by millions of cold sufferers every year, but there is no good evidence for or against the effectiveness of OTC cough medicines, concludes a new systematic review of studies. “I do not give my kids over-the-counter cough medicine,” said Thomas Fahey, professor of general practice at the Royal College of Surgeons in Ireland Medical School and review co-author. “I do not advise my patients to do so.” Another issue concerned the researchers, who wrote, “six out of the nine studies that were supported by the pharmaceutical industry showed […]
Public release date: 22-Jan-2008 The Cochrane reviewers analyzed 10 studies including 1,049 participants of all ages who received either cranberry products (juice or cranberry capsules), placebo juice or water for at least one month. Of the studies evaluated, there was no consistent dosage or concentration of cranberries given to the participants, but according to Jepson, there was a “typical amount” given daily. “The most common amount recommended is one glass twice a day,” Jepson said. “Trouble is, there is no general rule as to how long you have to drink that much in order for you to prevent one UTI.” […]
Public release date: 22-Jan-2008 Adding another twist to the ongoing debate over the value of an herbal treatment for patients with heart failure, a new review of existing research suggests that hawthorn extract “significantly” improves symptoms. “If I had chronic heart failure, I certainly would consider (using) it,” said review co-author Dr. Max Pittler, deputy director of complementary medicine at Peninsula Medical School in Exeter, England. The review of the studies appears in the latest issue of The Cochrane Library, a publication of The Cochrane Collaboration, an international organization that evaluates medical research. Systematic reviews like this one draw evidence-based […]
Public release date: 22-Jan-2008 In an appropriate prelude to American Heart Month, which is just ahead in February, new mortality data from the Centers for Disease Control and Prevention (CDC) shows that, since 1999, coronary heart disease and stroke age-adjusted death rates are down by 25.8 percent and 24.4 percent, respectively. This means that the American Heart Association’s 2010 strategic goal for reducing deaths from coronary heart disease has been achieved, and for stroke nearly achieved – ahead of time. However, potential problems loom for the future, as all of the major risk factors for these leading causes of death […]
