Zinc is an essential mineral that is naturally present in some foods, added to others, and available as a dietary supplement. Zinc is also found in many cold lozenges and some over-the-counter drugs sold as cold remedies.
Researchers invented a Compton camera of 580g which visualizes gamma rays of arbitrary energies, and succeeded in achieving a high-resolution, multicolor 3D molecular image of a live mouse administered with three different radioactive tracers in just 2 hours.
Antibiotics are an effective means of treating bacterial contamination. But extensive use of antibiotic substances in medicine and agriculture has resulted in increasingly antibiotic-resistant bacteria.
The harmful effects of the sun's ultraviolet (UV) rays are well publicised and the risk of developing skin cancer has scared many people into using a sunscreen product to protect their skin when exposed to the sun. However, a recent test of the performance of a range of marketed sun protection products revealed that many of them fail to provide adequate protection against UV rays.
Culinary treatments (boiling, microwaving, grilling, and deep frying) influence on proximate composition and antioxidant capacity of most cultivated mushrooms worlwide.
Sunscreen can be a valuable tool for skin cancer prevention -; but only if it's used correctly. When applying sunscreen, many people make mistakes that could compromise their protection from the sun's harmful ultraviolet rays, which may increase their risk of skin cancer.
Researchers at Aalto University, Finland, have developed anticancer nanomaterials by simulating the volcano-induced dynamic chemistry of the deep ocean.
According to a meta-analysis of three randomized controlled trials published in Open Forum Infectious Diseases, zinc acetate lozenges may increase the rate of recovery from the common cold three fold. On the fifth day, 70% of the zinc lozenge patients had recovered compared with 27% of the placebo patients.
A study in 65 countries has revealed low adoption of International Atomic Energy Agency recommendations to reduce nuclear cardiology radiation exposure.
There is no significant difference between zinc acetate lozenges and zinc gluconate lozenges regarding their efficacy in shortening the duration of common colds according to a meta-analysis published in Journal of the Royal Society of Medicine Open.
In addition to essential metabolic functions, the level of zinc in the body also affects the heart muscle. When oxidative stress occurs, it may be due to a shortage of zinc, which can be determined by examining the heart muscle.
The father's lifestyle affects the cognitive skills of his offspring -- at least in mice. Scientists at the German Center for Neurodegenerative Diseases have now shown that if male rodents are fed a diet rich in folic acid, methionine and vitamin B12, their progeny do not perform well in memory tests.
Drugs containing gold have been used for centuries to treat conditions like rheumatoid arthritis. In addition, they might be effective against cancer and HIV.
Growing up can be hard for any teenager without the added stress of acne. Sadly acne affects around 80% of adolescents aged 13-18 years at some point.
Connecting pieces of information by finding a common thread often takes glaucoma researchers in unexpected directions.
Zinc is a vital micronutrient involved in many cellular processes: For example, in learning and memory processes, it plays a role that is not yet understood. By using nanoelectrochemical measurements, Swedish researchers have made progress toward understanding by demonstrating that zinc influences the release of messenger molecules.
Nowadays, in order to improve sperm quality and fertility changes, many fertility clinics recommend simple lifestyle changes such as increased physical activity, cognitive behavioural therapy or yoga to reduce stress, give advice on how to reduce alcohol and caffeine intake and provide lists of dietary recommendations.
For years, parents of children with high blood lead concentrations have been advised by health experts to provide their kids foods rich in iron, calcium and vitamin C.
As the winter temperatures begin to thaw, many may be dreaming of a sun-drenched spring and summer, and some may be hoping to show off a tan. While these individuals may believe tanning makes them more beautiful, this habit can actually damage their skin in the long run.
Alzheimer's disease (AD) is one of the most common form of dementia. In search for new drugs for AD, the research team, led by Professor Mi Hee Lim of Natural Science at UNIST has developed a metal-based substance that works like a pair of genetic scissors to cut out amyloid-β (Aβ), the hallmark protein of AD.
Experiments show that Hedgehog signaling - a chain of molecular events critical in embryonic development - creates conditions beneficial to the unregulated cell growth associated with cancer in adults.
