Green tea compound aids p53, 'guardian of the genome' and tumor suppressor   An antioxidant found in green tea may increase levels of p53, a natural anti-cancer protein, known as the ''guardian of the genome'' for its ability to repair DNA damage or destroy cancerous cells. Rensselaer Polytechnic Institute,    February 21, 2022   An antioxidant found in green tea may increase levels of p53, a natural anti-cancer protein, known as the "guardian of the genome" for its ability to repair DNA damage or destroy cancerous cells. Published  in Nature Communications, a study of the direct interaction between p53 and the green tea compound, epigallocatechin gallate (EGCG), points to a new target for cancer drug discovery. "Both p53 and EGCG molecules are extremely interesting. Mutations in p53 are found in over 50% of human cancer, while EGCG is the major anti-oxidant in green tea, a popular beverage worldwide," said Chunyu Wang, corresponding author and a professor of biological sciences at Rensselaer Polytechnic Institute. "Now we find that there is a previously unknown, direct interaction between the two, which points to a new path for developing anti-cancer drugs. Our work helps to explain how EGCG is able to boost p53's anti-cancer activity, opening the door to developing drugs with EGCG-like compounds."   (NEXT)   Sweet discovery in leafy greens holds key to gut health   University of Melbourne (Australia), February 15, 2022    A critical discovery about how bacteria feed on an unusual sugar molecule found in leafy green vegetables could hold the key to explaining how 'good' bacteria protect our gut and promote health. The finding suggests that leafy greens are essential for feeding good gut bacteria, limiting the ability of bad bacteria to colonise the gut by shutting them out of the prime 'real estate'. Researchers from Melbourne and the UK identified a previously unknown enzyme used by bacteria, fungi and other organisms to feed on the unusual but abundant sugar sulfoquinovose - SQ for short - found in green vegetables. Dr Goddard-Borger said the discovery could be exploited to cultivate the growth of 'good' gut bacteria. "Every time we eat leafy green vegetables we consume significant amounts of SQ sugars, which are used as an energy source by good gut bacteria," he said.   (NEXT)   Using Qigong to manage COVID-19 in older adults   Massachusetts General Hospital, March 14, 2022   A study published in The American Journal of Geriatric Psychiatry reports on the possible usefulness of the integrative practice called Qigong to prevent and manage COVID-19 in older adults. Traditional Chinese Medicine (TCM) and Qigong are reported to have been valuable in controlling the spread of the pandemic in China. In field hospitals set up to isolate patients with mild disease, rather than practice home quarantine, patients were treated with Ba Duan Jin Qigong under the tutelage of TCM practitioners. This was both a valuable means of exercise and a therapeutic approach. In older people, the organ function declines, and chronic medical conditions set in, causing their energy to decline. This is thought of as a deficiency of Qi and blood. TCM practitioners say that Qigong may help prevent and promote recovery from respiratory infections in such conditions because of its regulatory function in the human body, including Wei Qi.   (NEXT)   "Cat's claw" extract inhibits replication of SARS-CoV-2 in vitro   University of Antioquia (Colombia) and Universidad Nacional Mayor de San Marcos (Peru), March 2, 2022   Researchers in Columbia and Peru have shown Uncaria tomentosa  or "Cat's claw" exerts in vitro antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19). The study found that the hydroalcoholic extract of Uncaria tomentosa inhibited SARS-CoV-2 viral replication and reduced its cytopathic effect on Vero E6 cells. Just 48 hours following treatment, the plaque reduction assay showed that U. tomentosaextract had inhibited the number of infectious SARS-CoV-2 particles by 92.7% at a dose of 25.0 µg/mL.   (NEXT)   How Tai Chi Proves to be a Gentle Solution for Improving Heart Health   Brown University School of Public Health, March 21, 2022   Some of the dietary and exercise changes and rehabilitation programs that doctors recommend to heart patients can seem more than a little intimidating, especially for inactive people. But a small study suggests that Tai Chi can be a gentle way for people with heart problems to get moving at a less overwhelming pace. One group practiced Tai Chi twice a week for 12 weeks by attending sessions at the hospital. The participants in the other group attended Tai Chi sessions three times a week for 24 weeks. Both groups received DVDs so that they could practice at home. Most of the 21 men and eight women in the study had also had a previous heart attack or had undergone bypass surgery to clear a blocked artery. All the volunteers were physically inactive and had rejected conventional cardiac rehabilitation, but expressed an interest in Tai Chi. Additionally, all continued to have high cardiovascular risk factors, such as high cholesterol, diabetes, obesity, overweight, and smoking. [2]
