Investigative Ophthalmology and Visual Science
A drug-dispensing contact lens
Taking eye drops multiple times a day can be difficult to do, and as little as 1 to 7 percent of the dose is actually absorbed by the eye. Now, researchers led by Daniel Kohane, M.D., Ph.D., director of the Laboratory for Biomaterials and Drug Delivery at Children's Hospital Boston, have developed special contact lenses that can gradually dispense a constant amount of medication to the eye, at adjustable rates.

1 step at a time: Motor molecules use random walks to make deliveries in living cells
Cells rely on tiny molecular motors to deliver cargo, such as mRNA and organelles, within the cell. The critical nature of this transport system is evidenced by the fact that disruption of motors by genetic defects leads to fatal diseases in humans. Although investigators have isolated these motor to study their function in a controlled environment outside the cell, it has been difficult for researchers to follow these fascinating molecular transporters in their natural environment, the living cell.

New breast cancer-promoting gene identified
Research has identified RCP as a new gene contributing to aggressive breast cancer behavior. Detailed analysis determined that one mechanism by which RCP promotes breast cancer is likely to be via activation of the RAS signaling pathway, a known tumor-promoting pathway. The authors hope the data generated in this study not only provide new insight into the cellular processes underlying breast cancer but also help identify potential new therapeutic targets.

Some Routine Cancer Screenings Not Proven To Reduce Deaths, Experts Say
Routine screenings for cancers -- including breast cancer in younger women -- have not proven to reduce the chance of death for people without specific symptoms or risk factors, and experts suggest that some tests could lead to harm, the
New York Times reports. According to Ned Calonge, chair of the United States Preventive Services Task Force, screening is only useful if it prevents enough deaths to outweigh harm from treatments that are not medically necessary. He said that although screening in some cases will detect life-threatening cancers that respond to intervention, it also can result in false positives that cause needless worry and unnecessary procedures. Screening also might fail to diagnose an existing cancer, causing patients to ignore symptoms; find slow-growing or stable cancers that are not life-threatening and normally do not need treatment; or find aggressive, life-threatening cancers that do not respond to treatment, Calonge said. Only a handful of screening tests have been proven to significantly reduce death among certain age groups: pap tests to screen for cervical cancer beginning no later than age 21; mammograms to screen for breast cancer starting at age 40; and colon cancer screening beginning at age 50. According to the Centers for Disease Control and Prevention, there is no medical proof that routine screening for many other cancers -- including ovarian cancer -- reduces deaths.

Oral Health The Key To Alzheimer's Cure?
A major research grant will help scientists study the links between memory and oral health in a bid to establish control over Alzheimer's disease. The news of a $1.3 million study to be carried out on thousands of participants has been welcomed by the UK's leading oral health charity - the British Dental Health Foundation. Research has long associated oral health with overall health problems, including dementia - though no studies have made clear how the state of the teeth and mouth affect mental function.

The Effect Of Dietary Factors On Dementia
Experts estimate that over 24 million people worldwide suffer from dementia, and many of these people live in low- and middle-income countries. Recently, there has been growing interest in whether dietary factors, particularly oily fish and meat, might influence the onset and/or severity of dementia. Oily fish are rich in omega-3 long-chain polyunsaturated fatty acids, which some studies suggest are positively related to cognitive function in later life. Conversely, there is a suggestion from some studies that increased meat consumption may be related to cognitive decline. To examine this, a group of international researchers studied older people in 7 middle- to low-income countries. You can read the results of their study in the August 2009 issue of the American Journal of Clinical Nutrition. Data from 14,960 participants (≥65 y of age) living in China, India, Cuba, the Dominican Republic, Venezuela, Mexico, and Peru were analyzed. Dietary habits were assessed by using standard, culturally appropriate face-to-face interviews, and dementia was diagnosed by using validated culturally and educationally fair criteria.

Seminal Finding Has Major Implications For The Development Of New And Better Vaccines
A research team led by the La Jolla Institute for Allergy & Immunology has identified the specific gene which triggers the body to produce disease-fighting antibodies -- a seminal finding that clarifies the exact molecular steps taken by the body to mount an antibody defense against viruses and other pathogens. The finding, published online today in the prestigious journal Science, has major implications for the development of new and more effective vaccines. The La Jolla Institute's Shane Crotty, Ph.D., was the lead scientist on the team, which also included researchers from Yale University. "The finding is enormous in terms of its long-term benefit to science and society as a whole because it illuminates a pivotal piece of the vaccine development puzzle -- that is, 'what is the molecular switch that tells the body to create antibodies?' Dr. Crotty has pinpointed the BCL6 gene and, in doing so, has answered a critical question that has long been sought by the scientific community," said Mitchell Kronenberg, Ph.D., president & scientific director of the La Jolla Institute, a nonprofit biomedical research institute. Dr. Kronenberg said this knowledge opens the door to developing ways to boost antibody production, thereby creating stronger and more effective vaccines.

A Potential Targeting Gene Therapy For Developing HCV
Gene therapy has emerged as a novel approach to combat HCV infection in the last few years. However, one of the most important obstacles to overcome is "targeting": the appropriate genes must be delivered and expressed in HCV infected hepatocytes without harming normal tissues. A research article published in the World Journal of Gastroenterology addresses this issue. The research team led by Professor Feng from Central South University cloned the 2'-5'oligoadenylate synthetase (OAS) promoter and investigated its activity in the HCV-core positive liver cells. Since the role of HCV-core protein in modulating OAS gene expression is very controversial, this article further investigates the relationship of HCV-core protein and OAS promoter in human embryo hepatocyte line L02.

Injectable Drugs Benefiting From Advances In Evolving Device Designs
As life expectancy increases in developed economies, the healthcare industry is preparing for a number of new challenges as well as opportunities. A longer life span is expected to translate to a growing number of patients diagnosed with chronic conditions. To counteract the financial and medical infrastructure implications of this trend, pressure from the public sector and managed care organizations will place a premium on therapeutic self-administration, an expectation that is creating an increased interest in routes of administration that are patient-friendly and cost-effective. Pharma company decision makers have come to the realization that for many products, success no longer only depends on the medication itself but also on achieving a consumer-compatible form of packaging and application. "For injectable drugs, the convergence of evolving device technology, high-performance materials, and innovative design concepts have led to the availability of syringes and injectors that offer an unprecedented level of human engineering, reliability, safety and patient-friendly features," explains George Perros, Greystone Associates Managing Director. "These devices are providing drug developers with the options they require to satisfy therapeutic targets as well as company business objectives."
