Abscorbic acid commonly known as Vitamin C is a water-soluble vitamin, which is necessary in the body to form collagen in bones, cartilage, muscle, and blood vessels and aids in the absorption of iron. Dietary sources of vitamin C include fruits and vegetables, particularly citrus fruits such as oranges.
Severe deficiency of vitamin C causes scurvy. Although rare, scurvy includes potentially severe consequences, and can cause sudden death. Patients with scurvy are treated with vitamin C and should be under medical supervision.
Many uses for vitamin C have been proposed, but few have been found to be beneficial in scientific studies. In particular, research in asthma, cancer, and diabetes remains inconclusive, and no benefits have been found in the prevention of cataracts or heart disease.
A team of pharmacists from the University of Santiago de Compostela (USC) has established that the levels of vitamin C in many fruit juices and soft drinks are far higher than those indicated on their labels by the manufacturers. This finding has been possible owing to a new technique developed by the researchers to determine the content of vitamin C in these kinds of drinks.
Bayer Diabetes Care today announced U.S. Food & Drug Administration clearance to market the CONTOUR(R) USB blood glucose meter. Bayer's CONTOUR USB meter is the first and only blood glucose monitor that plugs directly into a computer providing users with instant access to information that can help optimize diabetes management. The CONTOUR USB meter is integrated with Glucofacts(TM) DELUXE software for easy retrieval of data as well as longer-term tracking and analysis of blood glucose test results.
Salix Pharmaceuticals, Ltd. today announced the successful outcome of two Phase 3, randomized, double-blind, placebo-controlled, multicenter trials, TARGET 1 and TARGET 2, designed to evaluate the efficacy and safety of rifaximin 550 mg TID in the treatment of patients with non-constipation irritable bowel syndrome (non-C IBS).
Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP) today announced the U.S. Food and Drug Administration (FDA) has granted marketing approval for METOZOLV™ ODT (metoclopramide HCl) 5mg and 10mg orally disintegrating tablets. METOZOLV ODT is indicated for the relief of symptoms in adults associated with acute and recurrent diabetic gastroparesis and for the treatment of short-term therapy (4-12 weeks) for adults with symptomatic documented gastroesophageal reflux disease (GERD) who fail to respond to conventional therapy1.
Researchers at the University of Leicester and Institute for Molecular and Cellular Biology in Portugal studied new protective properties of vitamin C in cells from the human skin, which could lead to better skin regeneration.
Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP) today announced the Food and Drug Administration (FDA) has accepted for filing and designated for Priority Review the Company’s New Drug Application (NDA) for rifaximin tablets 550 mg for the maintenance of remission of hepatic encephalopathy (HE). Additionally, the FDA has informed the Company of its plan to schedule an Advisory Committee meeting in late February 2010 to discuss the application.
According to scientists in New Zealand, eating a raw tomato may not be the best way to access it s healthy antioxidants - they say a mere 4% of the antioxidant lycopene is released from raw tomatoes.
A review of previously published studies suggests that vegetable and nut intake and a Mediterranean dietary pattern appear to be associated with a lower risk for heart disease, according to a report published in the April 13 issue of Archives of Internal Medicine.
Serious flaws in a recent study, which concluded that high doses of vitamin C reduce the effectiveness of chemotherapeutic drugs in the treatment of cancer, are revealed in the current issue of Alternative and Complementary Therapies.
Gold nanoparticles are under consideration for a number of biomedical applications, such as tumor treatment. A German-American research team at Carnegie Mellon University in Pittsburgh, Hunter College in New York, and the RWTH Aachen has now developed a new method for the production of nanoscopic gold rods. In contrast to previous methods, they have achieved this without the use of cytotoxic additives.
High-dose injections of vitamin C, also known as ascorbate or ascorbic acid, reduced tumor weight and growth rate by about 50 percent in mouse models of brain, ovarian, and pancreatic cancers, researchers from the National Institutes of Health (NIH) report in the August 5, 2008, issue of the Proceedings of the National Academy of Sciences.
Increased consumption of teas rich in catechins is associated with reduced risk of stomach, colon and other gastrointestinal cancers.
A new study appears to explain how humans, along with other higher primates, guinea pigs and fruit bats, get by with what some have called an “inborn metabolic error”: an inability to produce vitamin C from glucose.
A study found that citrus juices enable more of green tea's unique antioxidants to remain after simulated digestion, making the pairing even healthier than previously thought.
The researchers analysed the impact of both fat (lipid) and vitamin C (ascorbic acid) on nitrite chemistry in the upper (proximal) stomach, which is especially vulnerable to pre-cancerous changes and tumour growth.
Researchers in the U.S. say middle-aged women at risk for heart disease derive little benefit from taking vitamins C, E or beta carotene.
Unless you run marathons, you probably won't get much protection from common colds by taking a daily supplemental dose of vitamin C, according to an updated review of 30 studies.
Scientists at the University of Glasgow found that in the presence of lipid the ability of antioxidants, such as ascorbic acid (the active component of vitamin C), to protect against the generation of potential cancer-forming compounds in the stomach is less than when no lipids are present.
Contradicting claims of disease prevention, an analysis of previous studies indicates that the antioxidant supplements beta carotene, vitamin A, and vitamin E may increase the risk of death, according to a meta-analysis and review article in the February 28 issue of JAMA: The Journal of the American Medical Association.
Researchers at the University of Adelaide have discovered a potential way to increase the amount of Vitamin C in grapes.
