Tooth Damage from OJ, Motor Function Loss from Lack of Social Interaction and Other News of Note

Posted Jul 08 2009 11:44am

OJ Worse for Teeth than Whitening, Researchers Say (PhysOrg)

Eastman Institute’s YanFang Ren, DDS, PhD, and his team determined that the effects of 6 percent hydrogen peroxide, the common ingredient in professional and over-the-counter whitening products, are insignificant compared to acidic fruit juices. Orange juice markedly decreased hardness and increased roughness of tooth enamel.

Unlike ever before, researchers were able to see extensive surface detail thanks to a new focus-variation vertical scanning microscope. “The acid is so strong that the tooth is literally washed away,” said Ren, whose findings were recently published in Journal of Dentistry. “The orange juice decreased enamel hardness by 84 percent.” No significant change in hardness or surface enamel was found from whitening… More

Less Frequent Social Activity Linked to More Rapid Loss of Motor Function in Older Adults (Science Daily)

Loss of muscle strength, speed and dexterity is a common consequence of aging, and a well-established risk factor for death, disability and dementia. Yet little is known about how and why motor decline occurs when it is not a symptom of disease.

Now, researchers at Rush University Medical Center have found that, among the elderly, less frequent participation in social activities is associated with a more rapid decline in motor function.

“It’s not just running around the track that is good for you,” said Dr. Aron Buchman, associate professor of neurological sciences at Rush University Medical Center. “Our findings suggest that engaging in social activities may also be protective against loss of motor abilities”… More

Nanotechnology: The New Asbestos? (Food Navigator)

The safety risks of nanotechnology use by the food industry could make it “the new asbestos”, says toxicologist Dr George Burdock of the Burdock Group.

Nanotechnology refers to controlling matter at an atomic or molecular scale measured in nanometers, or millionths of millimeters. In the food industry, the technology has excited manufacturers as its potential uses are explored, including detecting bacteria in packaging, or producing stronger flavors and colorings.

But Dr Burdock claims that manufacturers lack understanding about how particles can change when they are shrunk to nano-size, and the current economic situation has exacerbated potential dangers, as some cost-cutting companies could look to cheaper, less reliable safety assessments… More

30 “New” Toxic Chemicals to Avoid (The Daily Green)

California, the state with the nation’s most strict chemical reporting laws, is poised to identify another 30 chemicals that could cause cancer or reproductive and developmental health problems, according to the Natural Resources Defense Council, which led a coalition of labor and environmental groups seeking greater protection from suspect chemicals.

The newly listed chemicals are being made public as Gov. Arnold Schwarzenegger and the legislature, facing a budget crisis, plan to dissolve the office that tests chemicals.

They include several chemicals that people are likely to come into contact with – including household weed killers and insecticides, and gasoline additives; as well as many industrial chemicals used to manufacture plastics, adhesives, other chemicals and a variety of other products… More

Stress in the Womb Can Last a Lifetime (PhysOrg)

The Imperial researchers’ work has shown that maternal stress and anxiety can alter the development of the baby’s brain. This in turn can result in a greater risk of emotional problems such as anxiety or depression, behavioural problems such as Attention Deficit Hyperactivity Disorder, and being considerably slower at learning. Some studies have even suggested that it may increase the likelihood of later violent or criminal behaviour. Their findings have suggested that the effects of stress during pregnancy can last many years, including into adolescence.

Professor Vivette Glover, the lead researcher behind the exhibit from the Institute of Reproductive and Developmental Biology at Imperial College London, said: “We all know that if a mother smokes or drinks a lot of alcohol while pregnant it can affect her fetus. Our work has shown that other more subtle factors, such as her emotional state, can also have long-term effects on her child. We hope our exhibit will demonstrate in a fun way why we all need to look after expectant mothers’ emotional wellbeing… More
