(CNN) Scientists have created a new "super enzyme" that can break down plastic up to six times faster than their previous enzyme. A team of researchers that previously re-engineered a plastic-eating enzyme named PETase have now combined it with a second enzyme to speed up the process, according to a press release from the University of Portsmouth. The super enzyme could have major implications for recycling polyethylene terephthalate (PET), which is the most common thermoplastic used in single-use drinks bottles, carpets, and clothing. Project co-lead John McGeehan pictured in the laboratory. PET takes hundreds of years to degrade in the environment. PETase can break it down into its building blocks in a few days. John McGeehan, lead co-author and director of the Centre for Enzyme Innovation at the University of Portsmouth, told CNN that this latest development represents a huge stop towards using enzymes to recycle plastic and … [Read more...] about Scientists create ‘super enzyme’ that eats plastic bottles six times faster

Researchers at the Indian Institute of Science (IISc) have developed artificial enzymes that can successfully block reactivation and replication of the Human Immunodeficiency Virus ( HIV ) in the host’s immune cells . According to IISc made from vanadium pentoxide nanosheets, these nanozymes work by mimicking a natural enzyme called glutathione peroxidase that helps reduce oxidative stress levels in the host’s cells, which is required to keep the virus in check. “The advantage is that the nanozymes are stable inside biological systems and do not mediate any unwanted reactions inside the cells. They are also quite easy to prepare in the lab,” said Govindasamy Mugesh, Professor at the Department of Inorganic and Physical Chemistry. Anti-HIV drugs are only successful in suppressing the virus. … [Read more...] about Enzymes that can block HIV reactivation
Shahid Akhter, editor, ETHealthworld, spoke to Gaurav Kaushik , MD & CEO, Meteoric Biopharmaceuticals Pvt. Ltd.. to know more about existing challenges associated with food and dietary supplements market. Impact and challenges posed by Covid-19 on the food and dietary supplements market Food and dietary supplements have been in a huge demand, pre and post Covid. The best part that we have seen nowadays, there is lot of escalated demand. There are lot of things being talked about immunity and lots of plant based products have been used. The challenges, if I have to talk about, is first we have to make the products cost-effectively, you know, because lot of raw materials, lot of ingredients are being used to help build immunity and target a lot of, lifestyle diseases. So it has to be backed by a robust R&D, delivery system, like when we consume something, whether it is herbal or probiotic or enzyme which occupy the major segment of Food and Dietary supplement market. … [Read more...] about R&D done by small companies should be recognised and incentivised: Gaurav Kaushik, Meteoric Biopharmaceuticals
ROBERT KITCHIN/STUFF Dr Ayesha Verrall on why the Government is taking control of fluoridation. EXPLAINER: The Government will amend a long-dormant bill to shift control of water fluoridation discussions from local authorities to Director-General of Health, Dr Ashley Bloomfield. Hannah Martin looks at what fluoridation is, how it works, and what it means. The decision whether to fluoridate water supply is in the hands of individual councils, leading to varying uptake across the country. A proposed change would see the buck stop with Dr Ashley Bloomfield. Currently, close to 60 per cent of New Zealand’s population on reticulated water supplies – the piped water network – receive fluoridated water, approximately 2.5 million people. Associate Health Minister Dr Ayesha Verrall announced the move on decision-making on Thursday , saying it will result in a nationally-consistent approach based on evidence. The move has been hailed by health experts as a “victory for … [Read more...] about What is water fluoridation and how does it work?
Only a lung transplant could save the British Covid-19 patient's life, Vietnam’s health ministry on May 12 decided to conduct a lung transplant for a 43-year-old British Covid-19 patient who has been in critical condition for more than a month, Kinhtedothi.vn reported. A medical staff examines samples for Covid-19 testing at HCMC Hospital for Tropical Diseases. Photo: Quynh Tran Dr. Nguyen Van Vinh Chau, director of the Hospital for Tropical Diseases in Ho Chi Minh City, said that the CT (computed tomography) scan results have shown that the patient's lungs had turned to fibrosis and lost function. This condition means that the patient will die if the life support machine called Extracorporeal membrane oxygenation (ECMO) is terminated. Only a lung transplant could save the patient's life, Chau stressed, adding that the Ministry of Health has requested the National Organ Transplant Center under Vietnam - Germany Hospital to carry out the surgical procedure. … [Read more...] about Lung transplant indicated for British Covid-19 patient
