Arsenic is a naturally occurring element widely distributed in the earth’s crust. In the environment, arsenic is combined with oxygen, chlorine, and sulfur to form inorganic arsenic compounds. Arsenic in animals and plants combines with carbon and hydrogen to form organic arsenic compounds.
Breathing high levels of inorganic arsenic can give you a sore throat or irritated lungs.
Ingesting very high levels of arsenic can result in death. Exposure to lower levels can cause nausea and vomiting, decreased production of red and white blood cells, abnormal heart rhythm, damage to blood vessels, and a sensation of “pins and needles” in hands and feet.
Ingesting or breathing low levels of inorganic arsenic for a long time can cause a darkening of the skin and the appearance of small “corns” or “warts” on the palms, soles, and torso.
Cephalon, Inc. today announced the U.S. Food and Drug Administration (FDA) has granted a priority review for its supplemental New Drug Application (sNDA) for NUVIGIL(R) (armodafinil) Tablets [C-IV], which was filed in June of this year.
CytRx Corporation (NASDAQ:CYTR), a biopharmaceutical company engaged in the development and commercialization of human therapeutics, today announced the initiation of a dose escalation study with its oncology drug candidate tamibarotene combined with TRISENOX® (arsenic trioxide) injection (marketed by Cephalon, Inc.) in patients with relapsed acute promyelocytic leukemia (APL).
Space is not a fun place to get a stomach bug. To ensure drinking water is adequately disinfected, University of Utah chemists developed a two-minute water quality monitoring method that just started six months of tests aboard the International Space Station.
Large variations exist in peoples' ability to eliminate arsenic from the body, according to a new study that questions existing standards for evaluating the human health risks from the potentially toxic substance.
Most people would agree that arsenic, lead, mercury, benzene and carbon monoxide pose dangers to humans. Not many, though, realize that the average person is exposed to about 10,000 different chemicals per day.
Cephalon, Inc. (Nasdaq: CEPH) announced today that it has completed its previously announced acquisition of all of the outstanding ordinary shares of Australian biotechnology company, Arana Therapeutics Limited. As a result of the acquisition, Arana is now a wholly-owned subsidiary of Cephalon.
University of Michigan researchers have developed an animal model that provides strong evidence why imatinib, marketed as Gleevec, helps patients with chronic myeloid leukemia survive longer, but does not keep the disease from returning if treatment ends.
Arsenic trioxide has a long history as a potent human poison, but it also has proven valuable as one of the primary treatment options for acute promyelocytic leukemia. Efforts to use arsenic trioxide to treat other types of cancer are under way, but clinical trials are revealing that the extreme toxicity of this material is likely to limit its utility as a broad-spectrum anticancer agent.
Private well water should be tested yearly, and in some cases more often, according to new guidance offered by the American Academy of Pediatrics (AAP).
The ability to mount an immune response to influenza A (H1N1) infection is significantly compromised by a low level of arsenic exposure that commonly occurs through drinking contaminated well water, scientists at the Marine Biological Laboratory (MBL) and Dartmouth Medical School have found.
Arsenic may be tough, but scientists have found a Yellowstone National Park alga that's tougher.
Scientists from Leicester and Nottingham have devised a method for identifying levels of exposure to environmental arsenic - by testing toenail clippings.
How about the fact that even if you choose to smoke outside of your home or only smoke in your home when your children are not there - thinking that you're keeping them away from second-hand smoke - you're still exposing them to toxins?
Dioxins, environmental pollutants resulting from the production and combustion of chlorinated compounds, have been linked to an increase in ischemic heart disease (IHD) and cardiovascular disease (CVD) mortality rates, as reported in a review article in the November 2008 issue of the peer-reviewed journal Environmental Health Perspectives (EHP).
A EU-India consortium led by Queen's University Belfast has led to the development of technology which could provide safe drinking water for over 70 million people in South East Asia. The joint collaboration has resulted in the world's first low-cost technology to provide arsenic-free water to people in India and surrounding countries.
Scientists studying arsenic pollution have discovered a living sensor that can spot contamination. They have also discovered new bacteria that can clean up arsenic spills even in previously untreatable cold areas, microbiologists heard today (Monday 8 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.
Alternative medicine is in the news again with scientists in the U.S. saying they have found high levels of toxic metals in popular herbal medicines sold online.
While exposure to high concentrations of the element in drinking water and in the workplace has been shown to be associated with diabetes, little is known about the effect of lower levels on diabetes risk.
Inorganic arsenic, commonly found in ground water in certain areas, may increase the risk of developing type 2 diabetes, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health.
Amid recent reports of dangerous levels of arsenic being found in some baby rice products, scientists have found a protein in plants that could help to reduce the toxic content of crops grown in environments with high levels of this poisonous metal.
