Chocolate Is Good For You!

Written by Janette Blackwell

Great news onrepparttar chocolate front! Chocolate is good for you. Under certain circumstances.

Katherine Tallmadge, spokesperson forrepparttar 148907 American Dietetic Association, says, inrepparttar 148908 February 9, 2005, WASHINGTON POST, that “cacao, or cocoa beans, contain ‘flavanols,’ naturally occurring plant compounds also found in tea, red wine, and apples. Their properties have been studied as heart disease inhibitors.”

Carl L. Keen, chair ofrepparttar 148909 department of nutrition at University of California, Davis, states inrepparttar 148910 same article that “the flavanols in cocoa help maintain a healthy vascular system. They reduce blood clotting -- an aspirin like effect -- reduce oxidative damage and improve blood flow.”

Unfortunatelyrepparttar 148911 flavanols in chocolate are bitter and are mostly removed from processed chocolate. The level decreases with each step, fromrepparttar 148912 bean torepparttar 148913 cocoa powder, and ultimately to a finished product. But big manufacturers like Nestle and Mars Inc.(producers of M&Ms) are working on chocolate items that are -- what else? -- good for you. We can soon expect chocolate bars and candies that advertise their high level of flavanols. Inrepparttar 148914 meantime,repparttar 148915 only product that states its flavanol level is Mars’ Dove Dark Chocolate, which has 150 mg. in 1.3 oz., a high level. It also has 200 calories. We live in an imperfect world.

While we’re waiting for more high-flavanol products, Ms. Tallmadge recommends unsweetened cocoa powder, but notrepparttar 148916 alkalized “Dutch processed” kind, which has had its flavanols reduced. Next in desirability is semisweet or bittersweet chocolate with a high cocoa percentage. Some chocolates contain as much as 70 percent cocoa, but they can have as little as 35 percent. The percent of cocoa in milk chocolate can be even lower, and she does not recommend it. She says, “I recommend cocoa or an ounce per day of dark chocolate, which may be about 110 to 150 calories, depending onrepparttar 148917 chocolate. Any more than that and you’re probably going to take in too many calories for weight control.”

Ultrasound and Physical Therapy: An Introduction

Written by Jim Doree

Ultrasound is a therapeutic modality that has been used by physical therapists sincerepparttar 1940s. Ultrasound is applied using a round-headed wand or probe that is put in direct contact withrepparttar 148873 patient's skin. Ultrasound gel is used on all surfaces ofrepparttar 148874 head in order to reduce friction and assist inrepparttar 148875 transmission ofrepparttar 148876 ultrasonic waves. Therapeutic ultrasound is inrepparttar 148877 frequency range of about 0.8-1.0 MHz.

The waves are generated by a piezoelectric effect caused byrepparttar 148878 vibration of crystals withinrepparttar 148879 head ofrepparttar 148880 wand/probe. The sound waves that pass throughrepparttar 148881 skin cause a vibration ofrepparttar 148882 local tissues. This vibration or cavitation can cause a deep heating locally though usually no sensation of heat will be felt byrepparttar 148883 patient. In situations where a heating effect is not desirable, such as a fresh injury with acute inflammation,repparttar 148884 ultrasound can be pulsed rather than continuously transmitted.

Ultrasound can produce many effects other than justrepparttar 148885 potential heating effect. It has been shown to cause increases in tissue relaxation, local blood flow, and scar tissue breakdown. The effect ofrepparttar 148886 increase in local blood flow can be used to help reduce local swelling and chronic inflammation, and, according to some studies, promote bone fracture healing. The intensity or power density ofrepparttar 148887 ultrasound can be adjusted depending onrepparttar 148888 desired effect. A greater power density (measured in watt/cm2 is often used in cases where scar tissue breakdown isrepparttar 148889 goal.

Ultrasound can also be used to achieve phonophoresis. This is a non-invasive way of administering medications to tissues belowrepparttar 148890 skin; perfect for patients who are uncomfortable with injections. With this technique,repparttar 148891 ultrasonic energy forcesrepparttar 148892 medication throughrepparttar 148893 skin. Cortisone, used to reduce inflammation, is one ofrepparttar 148894 more commonly used substances delivered in this way.
