Circulatory‚ pulmonary‚ or hemoglobin transfer disorders are commonly responsible. Overproduction of lactate also occurs with cyanide poisoning or certain malignancies. Underutilization involves removal of lactic acid by oxidation or conversion to glucose. Liver disease‚ inhibition of gluconeogenesis‚ pyruvate dehydrogenase (thiamine) deficiency‚ and uncoupling of oxidative phosphorylation are the most common causes. The kidneys also contribute to lactate removal. Concerns have been raised regarding

maintains an ideal environment for the enzymes. The pancreas maintains blood glucose levels to about 3.6 to 6 mmol/l. The pancreas does this by measuring if the blood sugar level is too high or low‚ if it is not the correct level then a hormone is released. If the blood sugar level is too high insulin is released from the beta cells and causes glucose to enter body cells to be used for energy but sometimes can stimulate glucose to turn to glycogen in the liver. However‚ if it is too low then glucagon

Child bone fracture From Wikipedia‚ the free encyclopedia A child bone fracture is a medical condition in which a bone of a child (a person younger than the age of 18) is cracked or broken.[1]About 15% of all injuries in children are fracture injuries.[2] Bone fractures in children are different than adult bone fractures because a child’s bones are still growing. Also‚ more consideration needs to be taken when a child fractures a bone since it will affect the child in his or her growth[3] How

4A- The hypothesis was partially supported because glucose left the bag and is proven by the positive test on the surrounding water. Also the beaker turned orange because of osmosis which attests to glucose leaving the bag. Iodine Potassium Iodine and water entered the bag. This was proven by the color change in the starch test as the bag turned black also because of osmosis. The only thing that the hypothesis lacked was that starch did not move at all. The beaker stayed yellow before and after because

usually occurring after food deprivation.[2] The hypoglycemia is associated with raised ketone bodies and free fatty acids with suppressed insulin levels.[3] The most likely cause is an imbalance in the suppression of glucose utilization by ketone bodies and a limited rate of hepatic glucose production.[4] Diagnosis requires exclusion of other causes of hypoglycemia‚ particularly GH deficiency‚ hypopituitarism‚ adrenocorticotropic hormone (ACTH) unresponsiveness‚ and glycogen synthase deficiency‚ all
