The results of a new study, published in the September 2004 issue of Clinical Pharmacokinetics, showed that no significant drug-drug interaction occurred when WelChol. (colesevelam HCI) was co-administered with TriCor. (fenofibrate tablets).
.Female mice that are abnormally small due to gene "knockout" technology are also bad mothers whose poor parenting skills cause their young to die within a day or two of birth. The mice are far smaller than their normal counterparts, and females have particularly bad parenting skills - they don't build nests, nurse their young, or tend to their offspring, which die within a day or two as a result.
Thirty one yearlings sold at the Virginia Tech Middleburg Agricultural Research and Extension Center Oct. 10 brought $75,025. Fifty five registered buyers and more than 100 people attended the annual event at which horses that have been a part of research programs at the center are sold with proceeds used to support continuing pasture-based equine nutrition research.
Normal cells that live among the cancer cells in a tumor may not be the innocent bystanders they are usually assumed to be. A study here has found that the normal cells in tumors, known collectively as the tumor stroma, may lose more regions of DNA than do the cancer cells in the course of tumor development.
Newsworthy articles include the following research showing that: in a 1-year study of 3,416 patients with uncontrolled asthma, 41 percent of the participants achieved the stringent level of total control; replacement testosterone increased lean body mass and leg muscle strength in men with severe chronic obstructive pulmonary disease who had low male hormone levels; and instillation of metal-rich tiny particulate matter into the lungs of healthy subjects caused distinct airway inflammation.
The Massachusetts Biotechnology Council (MBC) Drug Discovery Committee and Northeastern University invite you to a new event in drug discovery technology. With the variety of new tools and knowledge available today to more rapidly develop advanced therapies, we have the "critical mass" in the Boston area to lead the world in drug discovery.
A perceptual decision-making hub at the front of the brain makes the call on whether you're looking at a face or a house - and likely many other things - scientists have discovered. It works by gauging the strength of competing signals from lower brain areas specialized for recognizing different objects. Its location in the human brain was not previously known.
Purdue University chemists have developed a fast, efficient means of analyzing chemical samples found on surfaces, resulting in a device that could impact everything from airport security to astrobiology to forensic science. They have found a way to test untreated samples right where they are found with a mass spectrometer that can fit in a backpack - all by creating a wand that can gather the samples from the environment quickly.
Building on their earlier work, Johns Hopkins researchers have discovered that an apparently nontoxic cellular "energy blocker" can eradicate large liver tumors grown in rats. Six months to more than a year after treatment was stopped, the rats are still cancer free.
Mission Pharmacal will do its part to help encourage action against osteoporosis, the preventable disease that today's Surgeon General's Report--Bone Health and Osteoporosis: A Report of the Surgeon General"--has warned will be a risk for half of all Americans older than 50 by 2020. The Surgeon General called for a coordinated public health approach that brings together a variety of public and private stakeholders in a collaborative effort to improve bone health.
Exercise might one day provide a non-invasive, non-pharmaceutical way to protect adults against the onset of symptoms of Parkinson's disease (PD). These findings, by investigators at St. Jude Children's Research Hospital, are published in a current, special issue of Molecular Brain Research, called "Molecular Aspects of Parkinson's Disease."
Researchers have found altered gene activity in people who suffer from major depression, a discovery that may one day help doctors better diagnose and treat the condition.
Northwestern University has received a major grant from the Juvenile Diabetes Research Foundation (JDRF) to advance technologies in the field of islet cell replacement for the treatment of type 1 diabetes.
A group of researchers from various disciplines at Northwestern University literally have peered into the brain to offer new evidence on the existence of false memories and how they are formed. Published in Psychological Science, the study used MRI technology to pinpoint the formation of memories that didn't actually happen. The authors conclude that a vividly imagined event can leave a memory trace in the brain that's very similar to that of an experienced event.
Collaborations between the Max Planck Institute for Polymer Research in Germany and the University of Houston are providing impetus for polymers research developments that range from improving display devices to genetic profiling. Opening the door to establishing a future joint research program between the two institutions, Rigoberto Advincula, associate professor of chemistry at UH, has organized a first-ever joint symposium between a Texas research group and the MPI-P held Oct. 18-19 in Mainz, Germany.
The annual Chinese-American Frontiers of Science symposium, sponsored by the National Academy of Sciences, provides award-winning young scientists from the United States and China with the opportunity to interact and discuss their research.
This issue of Nutrition Notes focuses on two recent studies from Tufts University on osteoporosis.
A Department of Energy consortium of national laboratories including Livermore and universities today signed an agreement with Second Sight Medical Products Inc. to jointly develop technology that could restore sight to those who have lost vision later in life.
A group of promising cancer-fighting compounds derived from a substance used in ancient Chinese medicine will be developed for potential use in humans.
The development of the medical identification chip, like recent advances in genetic testing, illustrate the importance of preserving the traditional right of patients to give or withhold consent for treatment and the disclosure their personal medical information.
An estimated 42 percent of Americans use herbal medicines or nutritional supplements. Many people taking these products and their physicians are unaware of the adverse reactions they can cause. An Oregon Health & Science University researcher reviewed reported cases of ocular side effects associated with these products. His findings are published in the American Journal of Ophthalmology this month.
New research indicates that the presence of intra-abdominal fat can predict the existence and severity of metabolic syndrome in obese, older women.
Rockefeller University scientists show that nerve cells in the developing brains of humans and other mammals move in a two-part "step" led by a structure within the cell called the centrosome.
Muscle wasting is associated with aging and a serious consequence of different diseases, including cancer and diabetes. Researchers at Joslin Diabetes Center, with the assistance of other collaborating researchers, have discovered an important biochemical pathway for muscle wasting--as well as a potential target for drug therapy. The study will be published in the Oct. 15 issue of the journal Cell.
Several hundred local elementary and middle school students in Washington, D.C., and Annandale, Va., will discover the contributions of chemistry to health and wellness Oct. 17-23 during the 16th annual National Chemistry Week celebration, a program sponsored by the American Chemical Society, the world.s largest scientific society.
