Scientists have identified a new, longer species of amyloid .-peptide that has the potential to be a new target for the treatment of Alzheimer's disease.
Scientists are one step closer to deciphering the molecular signaling process controlling innate immunity with the discovery that a molecule called IRAK1 regulates the expression of the anti-inflammatory cytokine IL-10. Because atherosclerosis patients often have elevated IL-10 levels, IRAK1 may be a viable target for developing therapeutics for atherosclerosis.
A new study reports higher arrest rates among drug offenders diverted to treatment during the first six months of California's Substance Abuse and Crime Prevention Acat, commonly known as Proposition 36. SACPA clients were 48 percent more likely to be arrested for a drug offense than clients entering treament through other criminal justice diversion procedures, and 65 percent more likely than those who reached treatment through other means.
Scientists at the NIDDK, one of the National Institutes of Health (NIH), have induced human insulin-producing cells of the pancreas to revert to islet precursor cells. These precursor cells are capable of expansion and appear to naturally and efficiently differentiate into clusters of islet-like cells. This work may help to clarify the natural lifecycle of the beta cell and may eventually have applications for diabetes treatment.
The Food and Drug Administration (FDA) has granted a fast track review of testosterone patches for women with low sex drive, despite concerns about insufficient data and potentially misleading marketing by their manufacturer Proctor & Gamble, claim two articles in this week's BMJ.
Women with recurrent miscarriage and infertility are undergoing tests and treatments that have no scientific rationale and are linked with known risks to mother and fetus, warn researchers in this week's BMJ.
Many parents are failing to recognise obesity and overweight problems in their children, according to a study on bmj.com today.
Genentech, Inc, of San Francisco, CA, earned top honors today in a ranking of the world's most respected biopharmaceutical employers. The ranking, determined from a survey conducted by an independent research firm commissioned by the business office of the journal, Science, will appear in a special supplement of the 26 November issue.
A new study from Columbia University Medical Center finds that stomach (gastric) cancer originates from bone marrow derived stem cells (BMDC), rather than from stomach stem cells, as previously thought. The study, "Gastric Cancer Originating from Bone Marrow-Derived Cells" is published in the current issue of Science.
A new study published in the New England Journal of Medicine confirms that stem cells derived from the umbilical cords of newborn babies are a viable and effective transplant source for thousands of leukemia patients who have no other treatment option.
At MEDICA 2004, the medical trade fair taking place in D.sseldorf, Germany, from 24-27 November 2004, the European Space Agency will introduce highly progressive methods in space medicine and their application on Earth.
The Food and Drug Administration (FDA) tried to discredit one of its own experts after he told a US Senate hearing that the FDA had failed to protect the public over rofecoxib (Vioxx), according to two articles published online by the BMJ today.
Gene mutations that impair the ability of photoreceptor cells to properly dispose of waste - and as a result cause the blinding eye disease retinitis pigmentosa - have been identified by vision researchers at the University of Utah's Moran Eye Center. The discovery raises concerns that carbonic anhydrase inhibitors (medications often used to treat both heart and eye diseases) may adversely affect vision.
Patients with cancers previously next to untreatable may have new hope because of a license agreement between Isotron of Norcross, Ga., and UT-Battelle, which manages Oak Ridge National Laboratory.
The dermal route of exposure to chlorpyrifos, a common agricultural pesticide, contributes substantially to workers' total exposure, according to researchers from the Johns Hopkins Bloomberg School of Public Health and the US Environmental Protection Agency. Accurate methods for estimating dermal exposure are necessary as they form the basis for assessing and protecting worker health.
What is abuse? According to research in the new book, International Perspectives on Family Violence and Abuse, a country's history and culture strongly influence what its residents consider to be unacceptable -- and acceptable -- examples of domestic violence and abuse. Edited by Kathleen Malley-Morrison, a professor of psychology at Boston University, the book's compelling country-by-country narratives present perceptions of family violence and abuse that reflect the day-by-day social and ecologic contexts in which people live.
A protein that the heart produces during its development could be redeployed after a heart attack to help the organ repair itself, researchers at UT Southwestern Medical Center at Dallas have found. The mouse-study finding could eventually lead to new treatments for heart disease in humans and could even change the way healthcare providers respond to people suffering from heart attacks. The research appears in today's edition of Nature and is available online.
Biogen Idec (NASDAQ: BIIB) and Elan Corporation, plc (NYSE: ELN) announced today that the U.S. Food and Drug Administration (FDA) has approved TYSABRI. (natalizumab), formerly referred to as ANTEGREN., as treatment for relapsing forms of multiple sclerosis (MS) to reduce the frequency of clinical relapses.
Many pharmacists aren't opposed to importing drugs to lower patients' costs as long as pharmacists have a role in ensuring safety and efficacy, says a study by the University of Illinois at Chicago and the University of Michigan.
Researchers have discovered that individual fibroblast cells contain independent, self-sustaining circadian (ca. 24 hr) clocks. Circadian clocks are important for synchronizing many physiological and behavioral processes to the day/night cycle.
Condoms are traditionally seen by reproductive health care workers as second-rate methods of barrier control against pregnancy, and so are not as strongly promoted as they should be for protection against HIV/AIDS
Low-glycemic load diets, those low in sugars with moderate levels of carbohydrates and not as low in fat and protein, may lower metabolism less when compared with low-fat diets, making the dieters feel less tired, cold and hungry, as well as improve cardiovascular risk factors, according to an article in the Nov. 24 issue of The Journal of the American Medical Association.
A nutritional scientist at the University of Alberta believes that chylomicrons, metabolized balls of fat and cholesterol that enter the blood stream after a meal, are the key to understanding why some people with low LDL cholesterol are still vulnerable to suffering a heart attack or stroke.
The New Jersey Center for Biomaterials has generated what it hopes to be the beginning of a technology transfer success story that originated through the work of Rutgers University Professor Joachim Kohn in his search for improved biomaterials.
Johns Hopkins researchers say there is growing evidence that stem cells gone awry in their efforts to repair tissue damage could help explain why long-term irritation, such as from alcohol or heartburn, can create a breeding ground for certain cancers.
