“Today I'm donating convalescent plasma,” Judy Lutkin said.“This will be my third time donating.” Lutkin had COVID-19 back in April. “I was pretty sick for about four or five days,” she said. Now she comes infrequently to donate plasma. “It doesn't hurt. It doesn't feel bad. It’s fairly easy.”Plasma is just one of the tools used in fighting coronavirus. As it gets donated, it goes to COVID patients.Since early April, when Vitalant started collecting these donations, they’ve collected more than 9,700 donations equaling more than 33,000 units.“You could help as many as five patients with one sitting,” Liz Lambert, Vitalant spokesperson, said.Vitalant is a nonprofit that collects blood for about 1,000 hospitals across the country.“Right now, there's an emergency need for convalescent plasma as we anticipate more patients will be getting that treatment, or hospitals will be wanting to use that treatment,” Lambert said.The FDA issued an emergency use authorization for convalescent plasma as a potential COVID-19 treatment in late August. Convalescent plasma is taken from the blood of someone who’s already contracted a particular illness, in this case, COVID-19.This isn’t the first time in history; it’s been used to treat a virus.“Convalescent plasma is a very historic and crude way of conferring so-called passive immunity to patients who have a viral or bacterial disease,” Doctor Phil Stahel, Chief Medical Officer at the Medical Center of Aurora, said.So far, this center has treated 100 COVID-19 patients using this method.“Studies have shown that convalescent plasma is very safe,” he said. “It has been recently used for Ebola and other viral diseases for which we do not have a vaccination.”Doctor Stahel said patients they treat who are significantly sick could recover within 24 to 48 hours.Here’s how it works.“Antibodies are proteins that we form in our blood that attack antigens once our immune system recognizes them. It takes weeks for these to develop,” Doctor Ralph Vassallo, Chief Medical & Scientific Officer for Vitalant, said.The antibodies are taken from a recovered patient and put in a patient who recently contracted the disease.“The idea of convalescent plasma is to give them, in that period, when the patient does not have their immune response, to help neutralize the virus and prevent it from infecting cells in the body,” Doctor Vassallo said. “Convalescent plasma has been used for over 100 years in respiratory infections, including influenza.”With more hospitals using convalescent plasma to help COVID-19 patients, blood donation centers hope to identify more plasma donors who have recovered from the virus.“Whether its blood or convalescent plasma, there is a constant need,” Lambert said.Vitalant checks every regular blood donor for the antibodies as well, in hopes of identifying more possible donors.“In the first couple of September, it’s been about 3.6% nationwide,” Dr. Vassallo said.Those interested in donating convalescent plasma need to meet the same requirements as a blood donor, like being 16 years old or older, and at least 110 pounds.However, they also need to have a doctor-referred case of COVID-19 or doctor-referred antibody test.“It is indeed the first line of defense, and we should treat those patients early. This is for the adult in patients who are severely sick and at risk of getting on a ventilator, which we try to avoid by all means,” Doctor Stahel said. 3450

A bacteria that was thought to have existed a century ago, but could never be found, has finally been discovered.California Institute of Technology (Caltech) microbiologists Jared Leadbetter and Hang Yuat, who discovered it, said in a press release that the bacteria feeds on manganese and uses the metal as their fuel source."This discovery from Jared and Hang fills a major intellectual gap in our understanding of Earth's elemental cycles, and adds to the diverse ways in which manganese, an abstruse but common transition metal, has shaped the evolution of life on our planet," said Woodward Fischer, professor of geobiology at Caltech, who was not involved with the study, in the news release.The study showed that the bacteria can use manganese to convert carbon dioxide into biomass, a process the scientists called chemosynthesis.The discovery came after an accidental and unrelated experiment with a chalk-like form of manganese, the scientists said.The research was published in the journal Nature on Tuesday.NASA and Caltech funded the study. 1061

(KGTV) - The Los Angeles Chargers made a list of the most in-demand team for National Football League tickets, a StubHub report showed Thursday. The team ranked at number 9 for 2019 season ticket sales. This is the first year the Chargers have made the top 10, according to StubHub. Other rankings: 1. Dallas Cowboys 2. Green Bay Packers 3. Chicago Bears 4. New England Patriots 5. Philadelphia Eagles 6. Cleveland Browns 7. Minnesota Vikings 8. Pittsburgh Steelers 9. Los Angeles Chargers 10. San Francisco 49ersChargers ticket sales are up 220 percent, even with the smallest venue in the league, StubHub analysts said. The team’s Oct. 13 game against the Steelers was the eighth most in-demand game for fall. “Historic franchises are continuing to draw fans in 2019,” Akshay Khanna, GM of NFL at StubHub. “The Cowboys, Packers, Bears and Patriots dominate StubHub’s Top 10 in-demand teams and each are up at least 20% in ticket sales from 2018. It really shows that loyal fan bases, histories of winning seasons and continued buzz throughout the offseason can continue to fuel high demand.” Quarterbacks Tom Brady, Drew Brees, and Aaron Rodgers held honors as the most popular players, based on eBay merchandise sales from July 2018 through July 2019. “Tom Brady continues to resonate most with eBay shoppers following his 2019 Superbowl win, according to fan gear sales on our marketplace,” said Sam Bright, Vice President of Merchandising at eBay. “We are, however,seeing increases in excitement for other players compared to our top 10 rankings of 2018. Odell Beckham, Jr., who ranked number 10 last year, is now the number five trending player following his move to the Cleveland Browns, and newcomers to the list include Eagles quarterback Carson Wentz, Rams running back Todd Gurley and Seahawks quarterback Russell Wilson – all fantasy football favorites.” Not only is the NFL popular in the U.S., ticket sales from international buyers rose 19 percent during the 2018 season. Canada, Mexico, Australia, the United Kingdom and Germany were the top buyers. 2076
