The removal of tissue using lasers. Use of a laser light to destroy or cut tissue.  

Pain in the eye caused by bright light. Severe photophobia. Pain in the eye caused by bright light. Discomfort caused by intense light, also known as photodynia.  

A type of phosphonecrosis, caused by inhaling phosphorus fumes, which results in disintegration of the bones of the lower jaw. The disease was once common among workers in match factories.  

An enzyme that aids the process of carbohydrate metabolism. Any enzyme that catalyzes the combination of an organic molecule (usually glucose) with a phosphate group. Phosphorylase is found in the liver and kidney, where it is involved in the breakdown of glycogen to glucose- 1 -phosphate. An enzyme that catalyzes the formation of glucose-1-phosphate from…

An acid which is very soluble in water and gives rise to acid, neutral and alkali salts. An acid formed by oxidation of phosphorus. The phosphoric acids are orthophosphoric acid, H3P04; pyrophosphoric acid, H4P207; metaphosphoric acid, HP03; and hypophosphoric acid, H4P206. The salts of these acids are phosphates. Orthophosphoric acid, a tribasic acid, is used…

Shining without producing heat.    

A necrotic condition affecting the kidneys, liver and bones, usually seen in people who work with phosphorus. The destruction of tissues caused by excessive amounts of phosphorus in the system. The tissues likely to suffer in phosphorus poisoning are the liver, kidneys, muscles, bones, and the cardiovascular system. Necrosis of the alveolar process in persons…

The presence of excess phosphates in the urine. The presence of an abnormally high concentration of phosphates in the urine, making it cloudy. The condition may be associated with the formation of stones (calculi) in the kidneys or bladder. An excessive amount of phosphates in the urine; often causing renal stones. An elevated level of…

A group of enzymes which are important in the cycle of muscle contraction and in the calcification of bones. An enzyme that catalyzes the removal of a phosphoryl group from a substrate. Enzyme that acts as a catalyst in reactions involving phosphorus. One of a group of enzymes capable of catalyzing the hydrolysis of phosphoric…
