Workouts may slow Tumor Growth…

The American College of Sports Medicine reviewed past research on how exercise can reduce the risk of developing some cancers by as much as 69%. The data also showed how exercise can improve treatment outcomes which in turn can prolong life. One line of thought is that exercise can lower inflammation in the body and therefore cultivate an environment that is less friendly to malignancies. In a new study performed at Karolinska Institute in Stockholm, scientists inoculated two groups of rodents with cancer cells. One group was allowed to be extremely active while the other remained sedentary. They noted that in the group that was active there was very little evidence of tumor growth.  The T cell (immune fighter) that they attributed this to is the CD8+ T cell. What they also discovered was when they suppressed this particular T cell, regardless of how much activity, tumor cell growth was no longer suppressed. They then isolated and injected the CD8+ t cell from active rodents into sedentary rodents and found that their tumor growth was suppressed. After removing blood from the active rodents, they determined that their blood contained a large amount of lactate produced from exercise. Bathing T cells in lactate produced stronger cancer fighting T cells. There appears to be a profound effect that exercise has on the ability of the T cells to suppress tumor growth and how these cells remain persistent in fighting cancer over a period of time.

An Extra Set of Salivary Glands…

The human body is so complicated. After years of cutting and dicing cadavers, we are still finding hidden unknown organs. Scientists in the Netherlands have discovered a fourth set of salivary glands hidden inside the nasal cavity. Until recently it was believed that there were only three major sets. Why is this important? Salivary glands are responsible for supplying spit. In turn, the mouth becomes lubricated allowing us to both speak and swallow. They help us fight off germs from entering the mouth and have great healing powers for infections in the mouth. Most important they help with tasting our food which is a major contributor to quality of life. The tissues that comprise these glands are extremely delicate, and doctors are extremely careful not to destroy them when using radiation. These two hidden glands may be a major funneling system for transporting fluid from the head to the base of the tongue. The new finding may help to answer the question why people who undergo radiation of the head and neck so often end up with so many of the effects of injured salivary glands. Since they were so well hidden, doctors, unaware of their existence, never took precautions to spare them. It is not clear at present if these glands exist in the whole population or in certain groups of people. The research needs to widen its study to include a more diverse population. It just goes to show what an incredible piece of anatomy our bodies are.

Zinc and Esophageal Cancer…

According to a study, the mineral Zinc may have a great deal to do with inhibiting the growth of cancer cells in the esophagus. Zinc is responsible for the activity of more than 300 enzymes, immune function, and apoptosis (cell death). Findings were published in The Federation of American Societies for Experimental Biology. Research was done using “florescent live cell imaging”. It stated that Zinc can possibly halt the production of cancer cells especially in the esophagus. By hindering overacting calcium signals to cells, it may stop the growth of cancer by selectively inhibiting their growth. They also found that normal cells were left free to grow. Zinc deficiency seems to be common in patients with cancer. It is extremely important for overall health since it allows cells to function properly. However, taking a supplement without the guidance of your physician can be dangerous since it may hinder the absorption of other minerals. A good way to increase your intake is to include foods rich in Zinc in your diet. Spinach, flaxseed (milled), beef, pumpkin seeds, legumes, dairy, seafood (shrimp, oysters, fish), eggs, whole grains and even very dark chocolate.

Let Sleeping Dogs Lie…

Research is showing that sleeping in the same room with your dog whether your pet is sharing the bed or just lying on the floor, is proving to be beneficial to our health. According to recent poles from dog owners 50% regard their pet as a member of the household and they no longer relegate him or her to a doghouse. In a study performed at the Mayo Clinic of Phoenix, 40 dogs and their masters participated. To monitor activity the dogs wore a Fit-bark and the Humans wore an Anti-watch 2. After 7 days they discovered that both the dogs and their owners slept soundly. Sleep efficiency of between 80 and 85% were recorded for both which is a high number for determining a good night’s sleep. It is possibly due to the fact that most people develop a sense of security with a dog somewhere near. For those who live alone the closeness can reduce loneliness which often leads to depression. Most owners slept better when the dog slept beside the bed as opposed to on it. However, this might not be a great idea if the dog is a puppy or if there is also a new baby in the room. Don’t get me wrong. I am not saying you should get a new pair of PJ’s for Fido but if he is insisting on lying next to your bed it may be a healthy move to consider.
