Latest research on ingredients that make chocolate, olive oil, tea healthful foods INDIANAPOLIS, Sept. 11, 2013 — The scientific spotlight focuses today on the healthful antioxidant substances in red wine, dark chocolate, olive oil, coffee, tea, and other foods and dietary supplements that are enticing millions of consumers with the promise of a healthier, longer life. The American Chemical Society, the world's largest scientific society, is holding a symposium on those substances during its 246th National Meeting & Exposition.

Reports in the symposium involve substances that consumers know best as "antioxidants," and that scientists term "phenolic derivatives." These ingredients, found naturally in certain foods and sold as dietary supplements, have been linked with health benefits that include reducing the risk of heart disease and cancer.

Entitled "Phenolic Derivatives for Food and Human Health," the symposium was held today. The meeting continues through Thursday in the Indiana Convention Center and downtown hotels. Thousands of scientists and others are expected for the meeting, which features almost 7,000 reports on new discoveries in science and other topics.

Among the topics:

The healthful effects of curcumin, found naturally in the spice, turmeric Substances in dried ginger that kill cancer cells How large intestine microbes interact with cranberry antioxidants in the diet Using biotechnology to make more effective antioxidants

Abstracts in the symposium appear below.

### A press conference on this topic will be held Tuesday, Sept. 10, at 2:30 p.m. in the ACS Press Center, Room 211 in the Indiana Convention Center. Reporters can attend in person or access live audio and video of the event and ask questions at http://www.ustream.tv/channel/acslive.

The American Chemical Society is a nonprofit organization chartered by the U.S. Congress. With more than 163,000 members, ACS is the world's largest scientific society and a global leader in providing access to chemistry-related research through its multiple databases, peer-reviewed journals and scientific conferences. Its main offices are in Washington, D.C., and Columbus, Ohio.

Curcumin, a natural polyphenol of turmeric, continues to receive considerable attention as potent antioxidant and anti-cancer agent. Numerous analogues of curcumin have been synthesized and screened for their improved biological activities. An assessment of anticancer activities of curcumin and its novel 15 analogues was conducted in vitro. Various biochemical and toxicological techniques were employed to assess the therapeutic action of the synthetic novel curcumin analogs in comparison to curcumin and Sorafenib™ (a clinically approved drug). Inhibition of the cancer cell (HepG2) proliferation assessed by MTS assay showed that compound 2-[(E)-3-(4-hydroxyphenyl)acryloyl]-6-[1-(4-hydroxyphenyl)meth-(E)-ylidene]-cyclohexanone exhibits the trongest anticancer activity compared to curcumin and Sorafenib™ (p END

New technology transforms research in viral biology

2013-09-11
Researchers at The Mount Sinai Medical Center have developed an innovative system to test how a virus interacts with cells in the body — to see, for example, what happens in lung cells when a deadly respiratory virus attacks them. In the journal Cell Host & Microbe, investigators say such a technique will not only speed basic research into viral biology, it will also help scientists improve vaccine production, generate novel antiviral compounds, and advance the development of viruses that attack cancer cells. "We have a powerful system in place today to investigate ...

Robots take over

2013-09-11
CORAL GABLES, FL (September 9, 2013) — Recently, the global financial market experienced a series of computer glitches that abruptly brought operations to a halt. One reason for these "flash freezes" may be the sudden emergence of mobs of ultrafast robots, which trade on the global markets and operate at speeds beyond human capability, thus overwhelming the system. The appearance of this "ultrafast machine ecology" is documented in a new study published on September 11 in Nature Scientific Reports. The findings suggest that for time scales less than one second, the financial ...

The American Academy of Orthopaedic Surgeons releases Choosing Wisely list

2013-09-11
Rosemont, Ill. – The American Academy of Orthopaedic Surgeons (AAOS) today released a list of specific tests or procedures that are commonly ordered but not always necessary in orthopaedics as part of the Choosing Wisely® campaign, an initiative of the ABIM Foundation. The list identifies five targeted, evidence-based recommendations that can support conversations between patients and physicians about what care is really necessary. The Academy's list identified the following five recommendations: Avoid performing routine post-operative deep vein thrombosis ultrasonography ...

Biologists uncover mechanisms for cholera toxin's deadly effects

2013-09-11
Biologists at the University of California, San Diego have identified an underlying biochemical mechanism that helps make cholera toxin so deadly, often resulting in life-threating diarrhea that causes people to lose as much as half of their body fluids in a single day. Two groups of scientists working on fruit flies, mice and cultured human intestinal cells studied cholera toxin, produced by the highly infectious bacterium Vibrio cholerae. They discovered the toxin exerts some of its devastating effects by reducing the delivery of proteins to molecular junctions that ...

Hottest days in some parts of Europe have warmed 4 times more than the global average

2013-09-11
Some of the hottest days and coldest nights in parts of Europe have warmed more than four times the global average change since 1950, according to a new paper by researchers from the Grantham Research Institute on Climate Change and the Environment at the London School of Economics and Political Science and the University of Warwick, which is published today (11 September 2013) in the journal 'Environmental Research Letters'. The researchers translated observations of weather into observations of climate change using a gridded dataset of observations stretching back to ...

Autistic children with better motor skills more adept at socializing

2013-09-11
CORVALLIS, Ore. – In a new study looking at toddlers and preschoolers with autism, researchers found that children with better motor skills were more adept at socializing and communicating. Published online today in the journal Research in Autism Spectrum Disorders, this study adds to the growing evidence of the important link between autism and motor skill deficits. Lead author Megan MacDonald is an assistant professor in the College of Public Health and Human Sciences at Oregon State University. She is an expert on the movement skills of children with autism spectrum ...

Tiny number of Asian carp could be big problem for the Great Lakes

2013-09-11
WATERLOO, Ont. (Wednesday, September 11, 2013) – A tiny number of Asian carp could establish a population of the invasive fish in the Great Lakes, according to new research from the University of Waterloo. Published this week in the journal Biological Invasions, research from Professor Kim Cuddington of the Faculty of Science at Waterloo indicates that the probability of Asian carp establishment soars with the introduction of 20 fish into the Great Lakes, under some conditions. "Although established Asian carp populations including the Silver and Bighead carps are widely ...

2013-09-11
They say a phone call can change your life and for colorectal or bowel cancer survivors this is true, a new study by a QUT researcher has found. Associate Professor Anna Hawkes, from QUT's Institute of Health and Biomedical Innovation, evaluated the effects of a telephone delivered program called CanChange aimed at improving health outcomes for people diagnosed with bowel cancer. The study was conducted at the Cancer Council Queensland and funded by the Australian Government, Cancer Australia. The CanChange program targeted health behaviours such as levels of physical ...

Global warming could change strength of El Niño

2013-09-11
Wednesday, September11: Global warming could impact the El Niño Southern Oscillation (ENSO), altering the cycles of El Niño and La Niña events that bring extreme drought and flooding to Australia and many other Pacific-rim countries. New research published in Nature Geoscience using coral samples from Kiribati has revealed how the ENSO cycle has changed over the past 4300 years. This research suggests that external changes have an impact on the strength and timing of El Niño events. "Our research has showed that while the development of La Niña and El Niño events is chaotic ...
