Connie Weaver, distinguished professor and head of the food and nutrition department, found that the bones of rats fed nonfat dry milk were longer, wider, more dense and stronger than those of rats fed a diet with calcium carbonate. Calcium carbonate is the most common form of calcium used in calcium-fortified foods and supplements. Weaver said the study, funded by the National Dairy Council, is the first direct comparison of bone properties between calcium from supplements and milk. It will be published in the August print issue of the Journal of Bone and Mineral Research and is online at http://www.jbmronline.org/ "A lot of companies say, 'If you don't drink milk, then take our calcium pills or calcium-fortified food, '" Weaver said. "There's been no study designed properly to compare bone growth from supplements and milk or dairy to see if it has the same effect.
Drinking cherry juice could help ease the pain for people who run, according to new research from Oregon Health & Science University presented at the American College of Sports Medicine Conference in Seattle, Wash. The study showed people who drank tart cherry juice while training for a long distance run reported significantly less pain after exercise than those who didn't. Post-exercise pain can often indicate muscle damage or debilitating injuries. In the study of sixty healthy adults aged 18-50 years, those who drank 10.5 ounces cherry juice (CHERRish 100% Montmorency cherry juice) twice a day for seven days prior to and on the day of a long-distance relay had significantly less muscle pain following the race than those who drank another fruit juice beverage. On a scale from 0 to 10, the runners who drank cherry juice as their "sports drink" had a 2 point lower self-reported pain level at the completion of the race, a clinically significant difference.
A study just published on bmj.com reports that supervised exercises are more effective than shockwave treatment to relieve chronic shoulder pain. Shoulder pain is the fourth most frequent type of musculoskeletal pain reported to general practitioners and physiotherapists. Physiotherapy, non-steroidal anti-inflammatory drugs, and steroid injections are often part of the treatment. Physiotherapy can consist of shockwave treatment, ultrasound, exercises and acupuncture. Although quite a few studies have suggested that shockwave treatment may not be effective, it continues to be used extensively. In order to find out more, a team of researchers based in Oslo, Norway studied the effectiveness of radial extracorporeal shockwave treatment using low to medium energy impulses delivered into the tissue.
Potentially debilitating Lyme disease doesn't afflict people everywhere that the ticks harboring it are found. At least not yet. A five-university consortium led by a Michigan State University researcher wants to find out why. "These ticks are on the move. As ticks expand into new areas, more people will likely become infected, " said MSU fisheries and wildlife assistant professor Jean Tsao, who will lead the four-year, $2.5 million study. "We have a really intriguing scientific puzzle to solve - many factors change as we move from north to south, and we need to be smart with our study design to unravel these, " she said. "Our study also has practical goals - we aim to provide the health community and the public in the various states with some reassurance, or warning, about what their future will hold for spread of Lyme disease.
Researchers at the National Institute of Standards and Technology (NIST), in collaboration with private industry and other government agencies, have produced a new reference material for beryllium. Beryllium, an exotic rare-earth metal used as a hardener in high-performance alloys and ceramics, can cause berylliosis - a chronic, incurable and sometimes fatal illness. The new reference material is expected to dramatically improve methods used to monitor workers' exposure and aid in contamination control as well as toxicological research. The use of beryllium in manufacturing dates back to the advent of the atomic age. One of the scientists involved with the famous Chicago experiment known as Chicago Pile-1 to create the first artificial self-sustaining nuclear reaction in 1942 died of berylliosis in 1988.
