As tough as it may be, however, enamel can be broken down by bacteria, forming cavities and eventually destroying the tooth. That's why dentists repair cavities by filling them with a material to replace the lost enamel. The most common such restorative is a material invented in the 19th-century known as amalgam -- the classic silver-black fillings many people have. http://www.physorg.com/news176994275.html Chemistry Mon, 09 Nov 2009 13:30:01 EST news176994275 (AP) -- Archaeologists have discovered a smaller prehistoric site near Britain's famous circle of standing stones at Stonehenge. http://www.physorg.com/news173774861.html Other Sciences Sat, 03 Oct 2009 07:48:25 EST news173774861 Laparoscopic splenectomy has become the gold standard intervention for the removal of the spleen, especially for benign causes. However, the organ's high anatomic location, fragility and generous blood supply makes the procedure an advanced laparoscopic operation. Furthermore, unlike patients with gall bladder stones, patients who need splenectomy for benign disorders are rare. These factors may prohibit the laparoscopic surgeon from becoming proficient in laparoscopic splenectomy. Measuring the expertise and setting a minimum number of procedures needed to be performed in order to be accepted as proficient in this rather rare operation has proved difficult. http://www.physorg.com/news172311821.html Medicine & Health Wed, 16 Sep 2009 10:10:02 EST news172311821 Researchers have found another reason to eat well: a healthy diet helps prevent kidney stones. Loading up on fruits, vegetables, nuts, low-fat dairy products, and whole grains, while limiting salt, red and processed meats, and sweetened beverages is an effective way to ward off kidney stones, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN). Because kidney stones are linked to higher rates of hypertension, diabetes, increased body weight, and other risk factors for heart disease, the findings have considerable health implications. http://www.physorg.com/news169402936.html Medicine & Health Thu, 13 Aug 2009 17:25:02 EST news169402936 Children on the high-fat ketogenic diet to control epileptic seizures can prevent the excruciatingly painful kidney stones that the diet can sometimes cause if they take a daily supplement of potassium citrate the day they start the diet, according to research from Johns Hopkins Children's Center. http://www.physorg.com/news167416767.html Medicine & Health Tue, 21 Jul 2009 19:40:01 EST news167416767 These solid masses that form in the kidneys can grow big enough to cause severe pain and even infection as they pass into the urinary tract. http://www.physorg.com/news167063117.html Medicine & Health Fri, 17 Jul 2009 15:25:32 EST news167063117 The most popular type of gastric bypass surgery appears to nearly double the chance that a patient will develop kidney stones, despite earlier assumptions that it would not, Johns Hopkins doctors report in a new study.

This gives the olive processing industry an opportunity to make valuable use of 4 million tonnes of waste in olive stones it generates every year and sets a precedent for the recycling of waste products as fuels. Researchers from the Universities of Jaén and Granada in Spain show how this can be achieved in a study published in the latest edition of the Society of Chemical Industry's (SCI) Journal of Chemical Technology & Biotechnology. http://www.physorg.com/news144527862.html Chemistry Wed, 29 Oct 2008 19:37:42 EST news144527862 Global warming is likely to increase the proportion of the population affected by kidney stones by expanding the higher-risk region known as the "kidney-stone belt" into neighboring states, researchers at UT Southwestern Medical Center and UT Dallas have found. http://www.physorg.com/news135274903.html Medicine & Health Mon, 14 Jul 2008 17:21:43 EST news135274903 [B]Procedure associated with kidney stone formation earlier than previously reported[/B] CHICAGO (June 26, 2008) - Morbidly obese patients who undergo a particular type of gastric bypass surgery called Roux-en-Y gastric bypass (RYGB) are at an increased risk of developing kidney stones - small, pebble-like deposits that can result in severe pain and require an operation to remove them - earlier than previously thought. These stones develop in patients within only a few months following the procedure rather than several months to years, according to research published in the June issue of the Journal of the American College of Surgeons. http://www.physorg.com/news133697540.html Medicine & Health Thu, 26 Jun 2008 11:12:20 EST news133697540
