Naoki Mori, the Japanese cancer researcher who has had 30 papers retracted by scientific journals, was asked to give his side of the story. In an e-mail, he acknowledged that his colleagues “were lax in certain regards in the preparation of papers,” but he denied having committed a grave offense. The studies were retracted because they used pictures from older papers, rather than from the experiments described in the studies. “I think this reuse is not a scientific misconduct,” Dr. Mori wrote. He and his colleagues studied the response of human cells to infection by bacteria and viruses. To measure...

In the fall of 2010, Dr. Ferric C. Fang made an unsettling discovery. Dr. Fang, who is editor in chief of the journal Infection and Immunity, found that one of his authors had doctored several papers. It was a new experience for him. “Prior to that time,” he said in an interview, “Infection and Immunity had only retracted nine articles over a 40-year period.” The journal wound up retracting six of the papers from the author, Naoki Mori of the University of the Ryukyus in Japan. And it soon became clear that Infection and Immunity was hardly the only victim...

A collagen-binding peptide with applications in wound healing has been developed by scientists in the US. The peptide is able to invade the strands of collagen, forming a strong and stable non-covalent bond at room temperature. Pendant drug molecules could be attached to the peptide and anchored at the wound site to aid wound healing. Representation of a collagen mimetic peptide (CMP) annealing to damaged collagen to anchor a molecule (X) in a wound bed Collagen is the most abundant protein in the body and makes up three quarters of the dry weight of skin. It is formed from three...

If health care costs are ever to be brought under control, the nation’s doctors will have to play a leading role in eliminating unnecessary treatments. By some estimates, hundreds of billions of dollars are wasted this way every year. So it is highly encouraging that nine major physicians’ groups have identified 45 tests and procedures (five for each specialty) that are commonly used but have no proven benefit for many patients and sometimes cause more harm than good. Many patients will be surprised at the tests and treatments that these expert groups now question. They include, for example, annual electrocardiograms...

If every aspect of a person’s DNA is known, would it be possible to predict the diseases in that person’s future? And could that knowledge be used to forestall the otherwise inevitable? The answer, according to a new study of twins, is, for the most part, “no.” While sequencing the entire DNA of individuals is proving fantastically useful in understanding diseases and finding new treatments, it is not a method that will, for the most part, predict a person’s medical future. So, the new study concludes, it is not going to be possible to say that, for example, Type 2...

The face of medical education is changing and patients may not like it one bit. “There is a movement towards principles and concepts rather than specific courses,” Bailus Walker, Jr. of the Howard University School of Medicine said on April 4, 2012 at a conference in Crystal City, VA. “Entrance to medical schools will be based on principles and concepts rather than biochemistry knowledge.” “The old departmental barriers and walls are coming down.” Dr. Walker thinks this is a good thing. He calls it a “convergence of disciplines.” “That will lead to more STEM education,” he said, referring to training...

WASHINGTON — Old checklist for doctors: order that test, write that prescription. New checklist for doctors: first ask yourself if the patient really needs it. Nine medical societies, including the American Society of Clinical Oncology and the American College of Cardiology, representing nearly 375,000 physicians are challenging the widely held perception that more health care is better, releasing lists Wednesday of tests and treatments their members should no longer automatically order. The 45 items listed include: * Don't repeat colonoscopies within 10 years of a first such test * Don't perform early imaging for most back pain * Don't do...

NEW YORK (Reuters) - In a move that threatens to further inflame concerns about the rationing of medical care, the nation's leading association of cancer physicians issued a list on Wednesday of five common tests and treatments that doctors should stop offering to cancer patients. The list emerged from a two-year effort, similar to a project other medical specialties are undertaking, to identify procedures that do not help patients live longer or better or that may even be harmful, yet are routinely prescribed

California's $3 billion stem cell agency, now more than 7 years old, has joined research partnerships with science and health agencies in eight foreign countries, the San Francisco institute announced. The agreements call for collaboration in efforts aimed at speeding stem cell research from the laboratory to the hospital, where researchers hope that basic human cells will be programmed to treat scores of human degenerative diseases. Research partnerships between American and foreign stem cell scientists are encouraged, but the California institute's funds would only be spent within the state, institute officials said. Alan Trounson, president of the California Institute for...

A vaccine delivered in an injection or nasal spray to prevent heart attacks could be available within five years. Scientists have discovered that the drug stimulates the body's immune system to produce antibodies which prevent heart disease by stopping fat building up in the arteries. It is the first time that the underlying cause of heart disease has been targeted. Current treatments focus on using drugs to reduce cholesterol levels and blood pressure. The vaccine can cut the build up of fat in arteries by up to 70 per cent, according to tests by researchers at Lund University in Sweden....

Canadian researchers find a simple cure for cancer, but major pharmaceutical companies are not interested. Researchers at the University of Alberta, in Edmonton, Canada have recently cured cancer, yet there is but little ripple in the news or on TV. It is a simple technique using a very basic drug. The method employs dichloroacetate, which is currently used to treat metabolic disorders, so there is no concern of side effects or other long term effects. The drug doesn’t require a patent, so anyone can employ it widely and cheaply compared to the costly cancer drugs produced by major pharmaceutical companies....

For years, Alexis Beery, 15, relied on daily doses of an incredibly potent inhalant and injections of adrenaline just to stay alive. Now she and her similarly sick twin brother, Noah, have gone from racing to the ER on a regular basis to racing to high-school track and volleyball practice — thanks to treatment designed specifically for their unique genetic makeup. Gene-specific treatments have been used for years for a handful of diseases. Women with breast cancer who are found to carry the BRCA1 or BRCA2 genetic mutation, for instance, can undergo a regimen tailored for that specific gene mutation....

Malik Sarsa Khan had lost five children before. So when his daughter Samreen Fatma (3), who was born seven years after the death of his last child, was diagnosed with liver cancer, Khan, a Pakistani driver, decided to "beg, borrow or steal" to fund her liver transplant surgery in India. Though the government of Punjab in Pakistan stepped in to help him financially, he was robbed off at gunpoint in the Pakistani border city of Lahore while on his way to India. A determined Khan, somehow, managed to reach Apollo Hospital in Delhi. When finding a liver donor became difficult,...

Recently, however, there have been rumblings within the medical profession that suggest that the enthusiasm for early diagnosis may be waning. Most prominent are recommendations against prostate cancer screening for healthy men and for reducing the frequency of breast and cervical cancer screening. Some experts even cautioned against the recent colonoscopy results, pointing out that the study participants were probably much healthier than the general population, which would make them less likely to die of colon cancer. In addition there is a concern about too much detection and treatment of early diabetes, a growing appreciation that autism has been too...

Nithin Tumma, whose research could lead to less toxic and more effective breast cancer treatments, received the top award of $100,000 at the Intel Science Talent Search 2012, a program of Society for Science & the Public. From medical treatments to alternative energy solutions, innovation has been top of mind in our nation's capital this week. Honoring high school seniors with exceptional promise in math and science, Intel Corporation and Society for Science & the Public (SSP) recognized the winners of the nation's most elite and demanding high school research competition, the Intel Science Talent Search. Nithin Tumma, 17, of...

Australian researchers have been astonished to discover a cure-all right under their noses — a honey sold in health food shops as a natural medicine. Far from being an obscure health food with dubious healing qualities, new research has shown the honey kills every type of bacteria scientists have thrown at it, including the antibiotic-resistant “superbugs” plaguing hospitals and killing patients around the world. Some bacteria have become resistant to every commonly prescribed antibacterial drug. But scientists found that Manuka honey, as it is known in New Zealand, or jelly bush honey, as it is known in Australia, killed every...

Two years ago, I started reading about vitamin D deficiency. In articles by Dr. Frank Lipkin and on Natural News, they explained the symptoms of vitamin D deficiency. Guess what? To my surprise and curiosity, a lot of the symptoms were like fibromyalgia. I went back through my paperwork and saw that the nurse had indeed told me to take vitamin D.

Ever since Sarah Palin’s end-of-life counseling “death panel” remarks exploded into national consciousness in 2009, I have researched the real power ObamaCare will have to overrule your doctor’s decisions about what’s best for your health care. Forget death panels. Starting in July 2014, if Barack Obama is still president, a 15-member board that he selects with Senate confirmation — the Independent Payment Advisory Board — will be in charge of deciding when to reduce government spending per capita (for each person) on health care. Opponents such as Congressman Phil Gingrey, R-Ga., who is also a doctor and the co-chairman of...

We’re overdosing on cholesterol-lowering statins, and the consequence could be a sharp increase in the incidence of Type 2 diabetes. This past week, the Food and Drug Administration raised questions about the side effects of these drugs and developed new labels for these medications that will now warn of the risk of diabetes and memory loss. The announcement said the risk was “small” and should not materially affect the use of these medications. The data are somewhat ambiguous for memory loss. But the magnitude of the problem for diabetes becomes much more apparent with careful examination of the data from...

NEW YORK) -- There’s new hope for people with Trimethylaminuria, a rare disorder that causes its sufferers to smell like dead fish. Researchers at the Monell Chemical Senses Center in Philadelphia recently won a $36,000 grant to study the genes behind the disorder—work scientists believe could lead to new developments in helping control the symptoms of Trimethylaminuria, also known as TMAU. ABC News introduced TV viewers to a TMAU sufferer in 2006: Former model and teacher Camille said TMAU endangered her career. “I was so focused on ‘Do I smell? Do I smell? Are they saying things? Are they whispering?...
