[35] [36] These findings demonstrated ascorbic acid's pro-oxidant capabilities to produce hydrogen peroxide and thus, proposed a possible pharmacological mechanism of action against cancer cells. Nonetheless, ascorbic acid's potential as an anti-tumour therapy is still dubious, as other pro-oxidant substances (such as menadione [37] [38]) have ...
Vitamin C megadosage is a term describing the consumption or injection of vitamin C (ascorbic acid) in doses well beyond the current United States Recommended Dietary Allowance of 90 milligrams per day, and often well beyond the tolerable upper intake level of 2,000 milligrams per day. [1]
Ascorbic acid efflux by embryos of dicot plants is a well-established mechanism of iron reduction and a step obligatory for iron uptake. [a] All plants synthesize ascorbic acid. Ascorbic acid functions as a cofactor for enzymes involved in photosynthesis, synthesis of plant hormones, as an antioxidant and regenerator of other antioxidants. [95]
Low urine urobilinogen levels may result from congenital enzymatic jaundice (hyperbilirubinemia syndromes) or from treatment with drugs that acidify urine, such as ammonium chloride or ascorbic acid. Elevated levels may indicate hemolytic anaemia (excessive breakdown of red blood cells RBC), overburdening of the liver, increased urobilinogen ...
The stool guaiac test involves fasting from iron supplements, red meat (the blood it contains can turn the test positive), certain vegetables (which contain a chemical with peroxidase properties that can turn the test positive), and vitamin C and citrus fruits (which can turn the test falsely negative) for a period of time before the test.
Laboratory abnormalities seen in those with leukostasis include a markedly elevated white blood cell count (hyperleukocytosis) and electrolyte abnormalities seen with tumor lysis syndrome such as high concentrations of potassium, phosphorus, and uric acid in the blood and a low level of calcium in the blood (due to being bound by high amounts ...

The objective of cancer screening is to detect cancer before symptoms appear, involving various methods such as blood tests, urine tests, DNA tests, and medical imaging. [ 1 ] [ 2 ] The purpose of screening is early cancer detection, to make the cancer easier to treat and extending life expectancy. [ 3 ]
