The Use of Proton Pump Inhibitors - Research is showing that the numbers of proton pump inhibitors (PPIs) are being over prescribed during hospital stays and subsequently on discharge. There are studies published that show there are opportunities for substantial cost savings in relation to PPI prescription if there were some clinical guidelines used across the board nationwide. In addition to the costs, there are also risks for devastating side effects of continued use. There is a need to have a more defined reason for the administration and continuation of PPI’s....   [tags: step therapy, prescription, hospitals]

Oil Speculation: The Enemy of the Pump - Over the last five to seven years, the American people have had to pay outrageous prices at the gas pumps, wildly fluctuating from under $2.00 a gallon or less to paying $4.00 a gallon or even higher for gasoline. This issue of paying unreasonable and unpredictable prices at the pump comes from the higher prices of oil. Most will say that oil prices fluctuate so because of conflicts in the Middle East or due to shortages of oil, but the simple reason of the oil prices go up so high is because of oil speculation....   [tags: Price of Oil, Oil Supply, Gasoline] 914 words

Proton Pump Inhibitors To Protect the Stomach - Proton pump inhibitors (PPI) are the drugs that reduce the secretion of gastric (stomach) acid. These drugs were introduced in the United States in the late 1980s. They have emerged as the standard of treatment for most acid-related disorders which causes dyspepsia. These disorders include gastroesophageal reflux disease (GERD), peptic ulcer disease, and Zollinger-Ellison syndrome, which is marked by excessive amounts of gastric acid. “Proton pump inhibitors are also successfully used for the treatment of Helicobacter pylori infection and upper gastrointestinal bleeding” (Der, 2003, p....   [tags: gastric acid, dyspepsia, lansoprazole]

Mass Transport Systems in the Human Body - Mass Transport Systems in the Human Body Living cells require regular supplies of oxygen and nutrients for metabolic reactions such as respiration. These important materials such as glucose need to get to living cells and the waste products such as ammonia and urea need to be removed. This diffusion of materials into cells and waste products out of cells (which may need to happen via active transport if it is against the concentration gradient) can easily happen in small, single cellular organisms as they have a large surface area : volume ratio and also have a short diffusion path to all cells so enough material can get to cells sufficiently quickly....   [tags: Papers] 765 words

The Ketogenic Diet and How It Helps with Epilepsy - ... Typically, the body breaks down carbohydrates into glucose, which is then used to fuel cellular respiration in our bodies. When the body lacks a sufficient amount of glucose to maintain the body’s energy needs, fatty acids in the mitochondria of liver cells undergo beta-oxidation, in which they are broken into acetyl CoA molecules. Through a series of reactions known as ketogenesis, the acetyl CoA is converted in ketone bodies, high energy molecules which have a unique ability to cross mitochondrial membrane and the blood-brain barriers, making them good sources of fuel for the central nervous system1....   [tags: brain, medicinal, food, diet] 804 words

The supporting experiment suggested that the diuretic effect is mediated by potassium ions retention but not sodium ions, as the absence of sodium ions did not prevent the diuretic effect of parsley (7)....   [tags: Herb, Large Myriad, Medical Conditions, UTI]
