Solar-Powered Toothbrush: No Toothpaste Required?

pmyw29jl.jpgResearchers at the University of Saskatchewan have developed a solar-powered toothbrush that doesn’t require toothpaste.

At the base of the brush is a solar panel, which transmits electrons to the top of the toothbrush through a lead wire. These electrons react with acid in the mouth, breaking down plaque without the help of toothpaste. It’s an advancement of a model described 15 years ago using a titanium dioxide rod which released electrons when illuminated.

The researchers are currently recruiting 120 teens to test the brush. The model is named Soladey-J3X and is manufactured by the Shiken company of Japan.

How Is Exercise Like Brushing Your Teeth?

This isn’t really plastic surgery related, but considering that I am always trying to get patients to get more active or to remain active, then maybe it is.  I like to tell my patients that I have the easy part, they have the hard part of maintaining the results.  This is especially true for the liposuction or abdominoplasty patients where keeping their weight in line is an issue to outcome in years to come.

There is a new article published in  Circulation: Journal of the American Heart Association earlier this week which looked at different types of exercise after a myocardial infarction (MI).

The authors,  Dr Margherita Vona et al, did a controlled trial using 209 patients who were referred to cardiac rehabilitation after having an MI.  These patients were then randomly assigned to one of four groups:  aerobic training, resistance training, both combined, or no exercise.

The researchers looked at flow-mediated dilation (improve blood vessel function) at baseline after 4 weeks of exercise, and then again one month after stopping training.  The flow-mediated dilation more than doubled with exercise, from about 4% to about 10% in all three exercise groups.  Those in the no exercise group had a small increase from the baseline 4% to about 5%.

The benefits of physical activity did not last when the activity ended.  Within a month of no exercise, the flow-mediated  function returned to baseline levels.

The important finding of this study is as Dr Vona said, “Long-term adherence to training programs is necessary to maintain vascular benefits on endothelial function.”

Exercise / physical activity has to be like “brushing your teeth”.  It needs to be something that you do regularly and not just once or this week, but for life.

It is not important which physical activity you choose to do, it is important that you do it.  It is important that you continue to be physically active on a regular basis.

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
