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.
Researchers in the US have developed a new multi-organ-on-a-chip to test how new drugs affect the human body's vital organs.
The Jan. 17 issue of the Journal of the American Medical Association features an important study about sepsis with an accompanying editorial by a University of Nebraska Medical Center expert.
Psoriasis is a skin disorder that affects at least 100 million individuals worldwide. Its economic impact is more than $10 billion annually in the U.S. alone.
The body’s immune system works by protecting against disease and potentially damaging foreign bodies. In some instances, it may become impaired, leading to overreaction to infection.
Wearable electronics that adhere to skin are an emerging trend in health sensor technology for their ability to monitor a variety of human activities, from heart rate to step count. But finding the best way to stick a device to the body has been a challenge.
News-Medical speaks to Brad Harrison and Artem Egorov about the analysis of common but potentially lethal compounds in food and beverages.
For many years, radioactive iodine which emits beta rays has been used for treatment of thyroid cancer. Generally, 5-year survival rates may exceed 90%.
At Booth 1230, Lumex Instruments will demonstrate the mercury analyzer RA-915M with the pyrolizer Pyro-915+, capillary electrophoresis system Capel-205, atomic absorption (AA) spectrometer MGA-1000, PCR analyzer AriaDNA and fluorescence analyzer Fluorat-02.
A technique that enables biologically active enzymes to survive the rigors of inkjet printing presents a promising alternative to routine blood screening exams faced by diabetic patients. The KAUST-led team used this approach to make disposable devices that can measure glucose concentrations in human saliva.
Vitamin C may reduce the harm done to lungs in infants born to mothers who smoke during their pregnancy, according to a randomized, controlled trial published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.
Nearly 15 percent of all chewing gum varieties sold promise to provide health-enhancing supplements to users, so Penn State researchers studied whether two vitamin-supplemented products were effective at delivering vitamins to the body. Their results validate the concept of gum as an effective delivery system for at least some vitamins.
Women who are unable to quit smoking during their pregnancy may reduce the harm smoking does to their baby's lungs by taking vitamin C, according to a new randomized, controlled trial presented at the ATS 2018 International Conference.
Vitamin C is best known as a nutrient. In high enough doses, however, vitamin C also shows potential against many cancers, according to recent studies. To successfully develop vitamin C (chemically named ascorbic acid) as a medication, it is crucial to probe its concentration in the body, thus ensuring safe and effective doses.
CANCER stem cells, which fuel the growth of fatal tumors, can be knocked out by a one-two combination of antibiotics and Vitamin C in a new experimental strategy, published by researchers at the University of Salford, UK.
Researchers measure the impact on cancer stem cell metabolism of 3 natural substances, 3 experimental pharmaceuticals and 1 clinical drug.
University of Alabama researchers soon will launch a study that looks at watermelon juice as a way to reduce heart disease.
Researchers from IBBL and the Luxembourg Centre for Systems Biomedicine of the University of Luxembourg have investigated the impact of variations in temperature and delays during blood sample processing on downstream metabolomics applications.
Researchers have identified a new signaling pathway that helps cancer cells cope with the lack of oxygen found inside tumors. These are the results of a study published in Nature Cell Biology on June 20, and led by researchers at NYU Langone Medical Center and its Laura and Isaac Perlmutter Cancer Center, Princess Margaret Cancer Center, the University of Toronto, Harvard Medical School and Oxford University.
Chronic exposure to alcohol interferes with the pancreas' ability to absorb vitamin C, potentially predisposing the body to pancreatitis and other pancreatic diseases, a new study in the American Journal of Physiology—Cell Physiology reports.
An engineer and an ophthalmologist are developing a portable sensor that can quickly and inexpensively determine whether an eye injury is mild or severe. The device, called OcuCheck, measures levels of vitamin C in the fluids that coat or leak from the eye.
