The hydroxyl radical has a very short in vivo half-life of approximately 10 −9 seconds and a high reactivity. [5] This makes it a very dangerous compound to the organism. [6] [7] Unlike superoxide, which can be detoxified by superoxide dismutase, the hydroxyl radical cannot be eliminated by an enzymatic reaction.
General surgery, gastroenterology gross stomach dilatation, pyloric obstruction Gastric outlet obstruction ( GOO ) is a medical condition where there is an obstruction at the level of the pylorus , which is the outlet of the stomach .
Esophagogastric junction outflow obstruction (EGJOO) is an esophageal motility disorder characterized by increased pressure where the esophagus connects to the stomach at the lower esophageal sphincter.
The potential genotoxicity of chromium(III) has been explored in recent literature, and it has been observed in vitro generating hydroxyl radicals and binding to DNA; however, in vivo genotoxicity of Cr(III) is not well-established and the toxicity of Cr(III) compounds is generally considered to be at least 100 times lower than that of Cr(VI ...
The radiation which is produced by low-energy mobile radiation systems has a limited range. For this reason, conventional walls are regarded sufficient to stop the radiation scatter produced in the operating room and no extra measures for radiation protection are necessary. This makes IORT accessible for more hospitals.
This process uses a single low-pressure blower and a valve that reverses the flow through the blower so that the regeneration phase occurs under a vacuum. Generators using this process are being marketed to the aquaculture industry. Industrial oxygen concentrators are often available in a much wider range of capacities than medical concentrators.
The Mayo Clinic diet, a program that adheres to this notion, was developed by medical professionals based on scientific research, so you can trust that this program is based on science, and not ...
Acute pancreatitis (AP) is a sudden inflammation of the pancreas.Causes include a gallstone impacted in the common bile duct or the pancreatic duct, heavy alcohol use, systemic disease, trauma, elevated calcium levels, hypertriglyceridemia (with triglycerides usually being very elevated, over 1000 mg/dL), certain medications, hereditary causes and, in children, mumps.
