Ancient martial arts fights Parkinson’s disease

A new study published in The New England Journal of Medicine shows that tai chi helps improve strength, balance, and physical function of those that suffer from Parkinson’s disease.

Parkinson’s disease is a neurodegenerative disease in which nerve cells in the brain that produce the chemical dopamine begin to die. The decrease in the production of dopamine results in movement impairments, loss of postural stability and many more problems that affect function and quality of life. According to Parkinson Society Canada, nearly 100, 000 Canadians have Parkinson’s disease and 1 in 300 people in Canada and the United States has Parkinson’s.

Tai chi is an ancient martial art that is characterized by slow, flowing movement and meditation that is practiced for both defense training as well as many health benefits.

The latest research recruited 195 patients who suffered movement and balance problems caused by Parkinson’s disease from four Oregon cities and randomly assigned them into three groups: tai chi, resistance training, or stretching. All patients in all three groups underwent two 60-minute sessions twice a week for 24 consecutive weeks. After 24 weeks, the patients in the tai chi group performed much better than the other two groups in many measures related to strength, balance, movement control, stride length, and functional reach.

What makes this finding more significant is that tai chi improves what current medications do not. Fuzhong Li, the study’s lead author, quoted in an interview with the New York Times, “Current medications do not work well in terms of providing impaired balance or postural instability.” Li added, “In fact, patients suffer a great deal of medication side effects which may lead to further deterioration in balance control.”

For those of you that are interested and have a few minutes of extra time, you may want to take a look at the short video of instructor Dr. Fuzhong Li, taken from “Tai Chi: Moving for Better Balance”, posted below.

Video creation tutorials

As you start thinking about your video and podcast projects, I thought I would post a couple tutorials about making videos from the Vimeo Video School. There are a lot more to be found if you follow the link, but here are a couple embedded right here on the blog that I think I particularly important. The first one includes some shooting basics and the second one discusses general video editing.

Video 101: Editing Basics from Vimeo Staff on Vimeo.

Depending on which piece of software you are using for the editing, you can watch a more detailed video about using Microsoft Movie Maker (on a PC) or iMovie (on a Mac).

It seems to be a little more advanced, but Lifehacker also has a series of tutorials about video editing.

Finally, there is also a page on the UBC Wiki about video production that includes tutorials and a whole bunch of links to other resources.

Happy shooting!

Developments in Nanotechnology: Diagnosis within minutes

Doctors and scientists all over the world have fought an uphill battle with cancer and infectious diseases for numerous years. Each time a drug is developed to fight them, they manage to grow a little bit stronger, a little more persistent, and way more determined to evade these treatments and survive within the human body.
Dr. Shana Kelley and her team of researchers from the University of Toronto have developed a portable device with a disposable chip that could detect cancer at the molecular level, in its earliest stages of development.

Science and Technology


This would allow doctors to provide a treatment before the disease becomes malignant or terminal. Its design unique in that doctors would only need to take a sample of blood, urine or just a simple swab from the cheek to perform the test. Also, since cancer usually starts localized one particular area, early detection at this stage would allow more people to receive help when the disease is easily treatable.

As Dr. Kelley states, this new development will completely revolutionize the way diagnostic tests are completed. Currently, it takes patients days or even weeks to get diagnosed with certain diseases or cancers from a quite painful and invasive biopsy. Statistics show that 29.6 percent of all deaths in Canada are attributed to cancer, so this new technology could potentially be able to lower that rate significantly. Furthermore, it would save the healthcare system millions of dollars.

Canadian Cancer Statistics


However, since this development is still in the early stages, I have to wonder just how accurate this test is and how will it be received all around the world. There are probably many developing nations who could use this type technology so it not only could potentially impact the medical field in the Americas but also around the world.

Water: The Healthiest Beverage?

There is no harm in drinking water, right?

Most of us would probably not think twice about the contents of our drinking water. The water that we get out of the tap actually contains added fluoride to help prevent tooth decay by protecting tooth enamel against acids. However, we can obtain fluoride naturally through eating various foods. Many of us may also use fluoride containing products, such as toothpastes, mouth gels, dental floss, and dietary supplements.

The Government of Canada first introduced water fluoridation in 1968. However, since then, the government has reduced the optimum level of fluoride four times. The most recent cutback was in 2008, where the optimum level was lowered to almost half the initial recommended amount in 1968.

Larger doses of fluoride may causes serious health issues, including dental fluorosis, weakened bones, or even bone cancer. Too much fluoride causes bone structure disturbances, decreases fertility, and accumulates in certain areas of the brain, which will affect behaviour and learning.

There is an ongoing debate about whether or not water fluoridation is the cause of the decline in tooth decay. However, many studies have shown that tooth decay have actually started to decline before the fluoridation of water. Furthermore, tooth decay in children who have used fluoridated water all their lives continues to decline, which means that there is probably another factor involved.

The safety level of fluoride in our drinking water remains questionable, and with so many health risks associated with excess levels of fluoride, as well as the exposure of so many fluoridated products, I believe that water fluoridation is both unnecessary and risky. Although fluoride does help prevent tooth decay, the possibility of excess fluoride intake outweighs the benefit.
