Butanone is the precursor to methyl ethyl ketone peroxide, which is a catalyst for some polymerization reactions such as crosslinking of unsaturated polyester resins. Dimethylglyoxime can be prepared from butanone first by reaction with ethyl nitrite to give diacetyl monoxime followed by conversion to the dioxime: [ 15 ]
Methyl ethyl ketone peroxide (MEKP) is an organic peroxide with the formula [(CH 3)(C 2 H 5)C(O 2 H)] 2 O 2. MEKP is a colorless oily liquid. It is widely used in vulcanization (crosslinking) of polymers. [3] It is derived from the reaction of methyl ethyl ketone and hydrogen peroxide under acidic conditions.
The Baeyer–Villiger oxidation is an organic reaction that forms an ester from a ketone or a lactone from a cyclic ketone, using peroxyacids or peroxides as the oxidant. [1] The reaction is named after Adolf von Baeyer and Victor Villiger who first reported the reaction in 1899.
Oxidative stress mechanisms in tissue injury. Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination).. Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage.

While the process might be unpleasant, we won't shy away from the stomach-churning details, explaining how hot dog manufacturers turn a slurry of slaughterhouse trimmings into perfect tube steaks.
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.Individuals with gastric outlet obstruction will often have recurrent vomiting of food that has accumulated in the stomach, but which cannot pass into the small intestine due to the obstruction.
Diagnosis of Roemheld syndrome usually begins with a cardiac workup, as the gastric symptoms may go unnoticed, and the cardiac symptoms are frightening and can be quite severe. After an EKG , Holter monitor , tilt table test , cardiac MRI , cardiac CT , heart catheterization , electrophysiology study , echocardiogram , and extensive blood work ...
Peptic ulcer disease is when the inner part of the stomach's gastric mucosa (lining of the stomach), the first part of the small intestine, or sometimes the lower esophagus, gets damaged. An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer. [1]
