"Once complete, this device will allow chemical analysis and diagnosis without removing samples from the patient. It will be useful for monitoring surgery patients, assessing severity of traumatic injury, and eva...Low-carbohydrate, high-protein diets increase risk of kidney stones and may raise bone loss risk
...d diet, researchers report in the journal. Subject readings improved to 581 mg per day during intake of the moderately carbohydrate-restricted diet. The researchers also report that net acid excretion rose from baseline levels of 61 milliequivalents per day to 116 mEq per day during the severely carbohydrate-...New imaging technology promises better breast cancer detection in early stages
...the number of false negative (i.e., missed tumors) readings could be reduced if the limitations of contemporary gamma cameras were overcome. In one of his studies, Dr. Khalkhali found that three out of four false negatives were in the middle part of the breast and out of range of close camera contact. Dr. K...Study of vision disorder leads to discovery of new family of ion channels
...el because patients with the disease have abnormal readings on electrooculograms, tests that measures ion movements in the eye. In addition, all people who inherit one copy of the mutated bestrophin gene and one normal copy of the gene have the disease. This fact led the scientists to believe that when the de...Fisheries forecasting in the Niger inner delta
