Hydrogen Peroxide is a chemical used in bleaches, dyes, cleansers, antiseptics, and disinfectants. In a concentrated form, it is toxic and irritating to tissues.
Researchers at Johns Hopkins Medicine report they have identified a biochemical pathway linking oxidative stress and the amino acid cysteine in Huntington's disease.
The bacteria that live in dental plaque and contribute to tooth decay often resist traditional antimicrobial treatment, as they can "hide" within a sticky biofilm matrix, a glue-like polymer scaffold.
Favism is a common hereditary disease, affecting around 400 million people worldwide. It is caused by a lack of the enzyme glucose-6-phosphate dehydrogenase (G6PD).
Blood counts are routinely carried out before operations, in cases of infection, or when testing for a variety of diseases, such as anemia and leukemia. A key value in this test is the number of red blood cells (erythrocytes).
A nanoparticle commonly used in food, cosmetics, sunscreen and other products can have subtle effects on the activity of genes expressing enzymes that address oxidative stress inside two types of cells.
There are many false beliefs and myths about the role of oxidants and antioxidants in the human body. Traditionally, oxidants are presented as harmful and antioxidants as health-promoting. However, scientists have known for many years that endogenous oxidants are essential chemical messengers that help keep up the functions of the organism.
Amorphous iron nanoparticles have a specific toxicity in tumor cells. In the journal Angewandte Chemie, Chinese scientists describe their design and synthesis of a special amorphous state of nanoparticulate iron, which can locally release reactive iron species in the acidic and hydrogen peroxide rich environment of cancer cells, providing new possibilities for theranostics and chemodynamic therapies.
Chromium supplements are widely consumed for their antidiabetic activity as chromium(III) enhances the insulin sensitivity of cells. In particular, orthomolecular practitioners believe in the beneficial effects of providing the body with extra amounts of essential trace elements.
There are two types of protection, sample protection keeps the sample away from contaminants in the air; and operator protection, which protects the scientist from harm from whatever they’re working on
TSO3 Inc., an innovator in sterilization technology for medical devices in healthcare settings, has granted Getinge Infection Control AB, a global leader in infection control solutions, exclusive global distributor rights to its FDA-cleared, STERIZONE VP4 Sterilizer for US$7.5 million, plus performance minimums
Robots are capable of all sorts of tasks to help better treat cancer: They connect oncologists to patients remotely, make incisions, staple them shut, deliver "nano" therapies--and they clean rooms. New research from Penn Medicine infection control specialists found that ultraviolet (UV) robots helped reduce the rates transmission of the common bacterial infection known as Clostridium difficile among cancer inpatients - mostly blood cancer patients, a group more vulnerable to hospital-acquired infections - by 25 percent. The interventions also saved about $150,000 in annual direct medical costs.
Antibiotic-resistant pathogens such as CPE and hospital-acquired infections like C.difficile or norovirus seem to be relentlessly lurking around NHS hospitals.
With the world's elderly population expected to double by 2050, understanding how aging affects the body is an important focus for researchers globally. Cardiovascular disease, the No. 1 cause of death worldwide, often is associated with aging arteries that restrict blood flow. Now, University of Missouri researchers have identified an age-related cause of arterial dysfunction, a finding that could lead to future treatments for some forms of vascular disease.
Today, in continued recognition of the Centers for Disease Control and Prevention's (CDC) Contact Lens Health Week, 1-800 Contacts is providing an overview on contact lens solution and how to best use it to keep lenses clean.
Tray tables, bed rails, light switches, and toilets: All are common vectors for swapping germs between patients and health care workers. While a new systematic overview in this week's Annals of Internal Medicine points to several promising cleaning tactics of these "high-touch surfaces," there's a lack of evidence as to which is the most effective at reducing healthcare-associated infections (HAIs).
Scientists from the Florida campus of The Scripps Research Institute have shown how aging cripples the production of new immune cells, decreasing the immune system’s response to vaccines and putting the elderly at risk of infection.
TSO3 Inc., an innovator in sterilization technology for medical devices in healthcare settings, today announced that the Company has received purchase orders for multiple devices from the US. The orders are the result of the collaborative relationship between Getinge Infection Control, its sales and service provider, and the Company.
Although the causes of many age-related diseases remain unknown, oxidative stress is thought to be the main culprit. Oxidative stress has been linked to cardiovascular and neurodegenerative diseases including diabetes, hypertension and age-related cancers. However, researchers at the University of Missouri recently found that aging actually offered significant protection against oxidative stress.
A clinical trial of a new investigational vaccine designed to protect against West Nile Virus infection will be sponsored by the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health.
TSO3 Inc., an innovator in sterilization technology for medical devices in healthcare settings, today announced the formation of a wholly owned subsidiary: TSO3 Corporation, structured under the laws of the State of Delaware, and located in the State of South Carolina, USA.
