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.
More than two billion people worldwide suffer from micronutrient malnutrition due to deficiencies in minerals and vitamins.
A research team led by Professor Hongzhe SUN, Norman & Cecilia Yip Professor in Bioinorganic Chemistry, Department of Chemistry, Faculty of Science, and Professor Kwok Yung YUEN, Henry Fok Professor in Infectious Diseases, Department of Microbiology, Li Ka Shing Faculty of Medicine of the University of Hong Kong (HKU), has discovered a novel antiviral strategy for treatment of COVID-19.
A team of researchers from various universities and institutes in Spain recently published a paper on the preprint server medRxiv,* in which they hypothesize that serum zinc levels have a significant influence on COVID-19 progression and thus may be a useful biomarker in predicting severe disease in early stages of COVID-19 infection.
An international team of scientists has developed computational models to re-analyze and validate experimentally-derived publicly available macromolecular structures of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Pollution particles, including metals, have been found in the placentas of fifteen women in London, according to research led by Queen Mary University of London.
Using a device that could be built with a dollar's worth of open-source parts and a 3D-printed case, researchers want to help the hundreds of millions of older people worldwide who can't afford existing hearing aids to address their age-related hearing loss.
A new study published on the preprint server bioRxiv* in August 2020 shows that the man-made compound silicon nitride, which is used in medical implants and high mechanical performance engineering applications, is capable of inactivating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at varying concentrations without causing cell cytotoxicity. This finding should be investigated to develop disinfectants to clear the virus from surfaces, preventing its spread.
The human genome contains over 4.5 million sequences of DNA called "transposable elements", these virus-like entities that "jump" around and help regulate gene expression.
A University of Houston researcher is developing a new set of metal sensors that will be able to function in the gastrointestinal tract, a low oxygen environment, to examine how gut bacteria respond when trace metal nutrients, like iron and zinc, are thrown out of balance either through diet or disease.
Older adults who took a daily multivitamin and mineral supplement with zinc and high amounts of vitamin C in a 12-week study experienced sickness for shorter periods and with less severe symptoms than counterparts in a control group receiving a placebo.
Now, a new study published on the preprint server bioRxiv in August 2020 reports the discovery of two inhibitors of the helicase enzyme, which is essential for viral replication and the most highly conserved non-structural coronavirus (CoV) protein.
Antibiotic resistance is an increasing health problem, but new research suggests it is not only caused by the overuse of antibiotics. It's also caused by pollution.
Scientists have unveiled a correlation between high blood lead levels in children and methylation of genes involved in haem synthesis and carcinogenesis, indicating a previously unknown mechanism for lead poisoning.
A study led by researchers at Florida Atlantic University's Harbor Branch Oceanographic Institute examined toxins in tissue concentrations and pathology data from 83 stranded dolphins and whales along the southeastern coast of the United States from 2012 to 2018.
Finding out if the food and water we consume are safe from toxic and carcinogenic metals can now be much faster and simpler.
Millions of people, including the president of the United States, have seen or shared a video in which a doctor falsely claims there is a cure for the coronavirus, and it's a medley starring hydroxychloroquine.
The current COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), seems to attack the human airway epithelium primarily. In severely affected patients, the illness progresses to hypoxemic respiratory failure and acute respiratory distress syndrome (ARDS). The latter is treatable mainly by supportive management.
Researchers from Sechenov University in collaboration with colleagues from Germany, Greece and Russia reviewed scientific articles on the role of zinc in the prevention and treatment of viral infections and pneumonia, with projections on those caused by SARS-CoV-2. The results were published in the International Journal of Molecular Medicine.
Ongoing research around protective immunity against COVID-19 has not yet helped to define ways of how the public can protect themselves from the illness, minimize the symptoms, and avoid re-infection.
Now, a new study published on the preprint server bioRxiv in June 2020 attempts to make sense of this data to identify viral genes that are explicitly expressed in the cells infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This could help reveal new therapeutic targets.
