New evidence on easing inflammation of brain cells for Alzheimer's disease

2012-10-04
(Press-News.org) New research proves the validity of one of the most promising approaches for combating Alzheimer's disease (AD) with medicines that treat not just some of the symptoms, but actually stop or prevent the disease itself, scientists are reporting. The study, in the journal ACS Medicinal Chemistry Letters, also identifies a potential new oral drug that the scientists say could lead the way.

Wenhui Hu and colleagues point out that existing drugs for AD provide only "minimal" relief of memory loss and other symptoms, creating an urgent need for new medicines that actually combat the underlying destruction of brain cells. Research suggests that inflammation of nerve cells in the brain is a key part of that process. One medicine, Minozac, is in clinical trials. But Hu says Minozac still has more space to improve its efficacy. So the scientists sifted through compounds with a molecular architecture similar to Minozac in an effort to find more active substances.

The report describes success in doing so. They discovered one compound that appeared especially effective in relieving nerve inflammation and in improving learning and memory in lab mice widely used in AD research. "In general, this study not only proves that countering neuroinflammation is indeed a potential therapeutic strategy for Alzheimer's disease, but also provides a good lead compound with efficacy comparable to donepezil [an existing AD medicine] for further oral anti-AD drug discovery and development," the report states.

Ensuring high-quality dietary supplements with 'quality-by-design'

2012-10-04
If applied to the $5-billion-per-year dietary supplement industry, "quality by design" (QbD) — a mindset that helped revolutionize the manufacture of cars and hundreds of other products — could ease concerns about the safety and integrity of the herbal products used by 80 percent of the world's population. That's the conclusion of an article in ACS' Journal of Natural Products. Ikhlas Khan and Troy Smillie explain that the U.S. Food and Drug Administration (FDA) regulates dietary supplements as a category of foods, rather than drugs. Manufacturers are responsible for ...

A complete solution for oil-spill cleanup

2012-10-04
Scientists are describing what may be a "complete solution" to cleaning up oil spills — a superabsorbent material that sops up 40 times its own weight in oil and then can be shipped to an oil refinery and processed to recover the oil. Their article on the material appears in ACS' journal Energy & Fuels. T. C. Mike Chung and Xuepei Yuan point out that current methods for coping with oil spills like the 2010 Deepwater Horizon disaster are low-tech, decades-old and have many disadvantages. Corncobs, straw and other absorbents, for instance, can hold only about 5 times their ...

Celebrating the centennial of a landmark in culinary chemistry

2012-10-04
Billions of people around the world today will unknowingly perform a chemical reaction first reported 100 years ago. And the centennial of the Maillard reaction — which gives delightful flavor to foods ranging from grilled meat to baked bread to coffee — is the topic of a fascinating article in the current edition of Chemical & Engineering News. C&EN is the weekly news magazine of the American Chemical Society, the world's largest scientific society. Sarah Everts, C&EN senior editor, explains in the article that French chemist Louis-Camille Maillard took a first stab ...

Rice U. study: State deregulation of open-heart surgery beneficial to patients

2012-10-04
Certificate of Need, a form of state government regulation designed to keep mortality rates and health care costs down, appears to do neither for heart bypass surgery, according to a health economics researcher at Rice University and Baylor College of Medicine (BCM). Her findings are reported in an article appearing in today's online edition of the journal Medical Care Research and Review. Lead author Vivian Ho, the chair in health economics at Rice University's Baker Institute for Public Policy and a professor of medicine at BCM, found that states that removed Certificate ...

The mathematics of leaf decay

2012-10-04
CAMBRIDGE, MA -- The colorful leaves piling up in your backyard this fall can be thought of as natural stores of carbon. In the springtime, leaves soak up carbon dioxide from the atmosphere, converting the gas into organic carbon compounds. Come autumn, trees shed their leaves, leaving them to decompose in the soil as they are eaten by microbes. Over time, decaying leaves release carbon back into the atmosphere as carbon dioxide. In fact, the natural decay of organic carbon contributes more than 90 percent of the yearly carbon dioxide released into Earth's atmosphere ...

Newborn mortality was higher for several years after large-scale closures of urban maternity units

2012-10-04
After a series of Philadelphia hospitals started closing their maternity units in 1997, infant mortality rates increased by nearly 50 percent over the next three years. The mortality rates subsequently leveled off to the same rate as before the closures, but pediatric researchers say their results underscore the need for careful oversight and planning by public health agencies in communities experiencing serious reductions in obstetric services. Between 1997 and 2007, 9 of 19 obstetric units closed in Philadelphia, resulting in 40 percent fewer obstetric beds. Other research ...

Simple test may ease management of esophagitis

2012-10-04
A simple new test, in which the patient swallows a string, can monitor treatment of eosinophilic esophagitis as effectively as an invasive, expensive and uncomfortable procedure that risks complications, particularly in children. Researchers from the University of Illinois at Chicago College of Medicine, working in collaboration with clinician-investigators at the University of Colorado Denver/Children's Hospital Colorado and Lurie Children's Hospital in Chicago, reported their findings in a study published recently online in the journal Gut. Eosinophilic esophagitis, ...

Group therapy is an effective treatment option for depressed women with Type 2 diabetes

2012-10-04
MAYWOOD, Ill. – Gender-specific group therapy is effective for treating depressed women with Type 2 diabetes, according to a study published in the latest issue of the Annals of Behavioral Medicine and funded by the National Institute of Nursing Research. Evidence suggests that antidepressants may disrupt blood-sugar control and can be associated with increased weight gain; therefore, other treatment options are needed for depression. "Using antidepressants to treat depression, although important, can be associated with side effects that make compliance an issue for people ...

New study sheds light on cancer-protective properties of milk

2012-10-04
Amsterdam, The Netherlands, October 3, 2012 – Milk consumption has been linked to improved health, with decreased risks of diabetes, metabolic syndrome, and colon cancer. A group of scientists in Sweden found that lactoferricin4-14 (Lfcin4-14), a milk protein with known health effects, significantly reduces the growth rate of colon cancer cells over time by prolonging the period of the cell cycle before chromosomes are replicated. In a new study, investigators report that treatment with Lfcin4-14 reduced DNA damage in colon cancer cells exposed to ultraviolet (UV) light. ...

Not getting sleepy? Stanford research explains why hypnosis doesn't work for all

2012-10-04
STANFORD, Calif. — Not everyone is able to be hypnotized, and new research from the Stanford University School of Medicine shows how the brains of such people differ from those who can easily be. The study, published in the October issue of Archives of General Psychiatry, uses data from functional and structural magnetic resonance imaging to identify how the areas of the brain associated with executive control and attention tend to have less activity in people who cannot be put into a hypnotic trance. "There's never been a brain signature of being hypnotized, and we're ...
