SAN DIEGO (KGTV) — The National Institutes of Health highlighted research Tuesday out of UC San Diego that could unlock a new way to treat COVID-19.The research reveals new insight into how the coronavirus hijacks cells, and how doctors might be able to set traps or decoys to combat the virus. The findings were published in the journal Cell last month.“It does open up another avenue for a potential treatment,” said UC San Diego distinguished professor Dr. Jeffrey Esko. “It’s not a cure. It would be something that would tamp down infection potentially.”Since January, scientists around the world have understood that SARS-Co-V2, the official name of the new coronavirus, enters cells by latching onto a specific receptor on the cell’s surface, called ACE2.The UCSD team, led by Dr. Esko and visiting scholar Dr. Thomas Clausen, discovered that this entry mechanism is actually a two-step process, and the virus must also attach to a long chain of sugars called heparan sulfate.“We’ve shown this is fundamental to the infectious mechanism, so it needs to be part of every study from now on,” said Clausen.All cells are coated with a complex layer of sugars, or carbohydrates, called glycans. Heparan sulfate is one type of glycan that is known to play a key role in the infection process in several viruses, including herpes and other coronaviruses.It’s a complicated process to picture so the researchers offer an analogy: imagine a bird, soaring over trees, hunting a worm on the forest floor. The bird is the coronavirus and the trees are the thick layer of glycans that coat the surface of the cell.To reach the worm, which in this case is the receptor ACE2, the bird must navigate its way through the trees, specifically through heparan sulfate.The UCSD found that by removing the heparan sulfate trees with an enzyme, they were able to prevent the virus from infecting cells. In laboratory testing, they also found a second technique worked to foil the virus: introducing more trees as bait.The team found that heparin, an FDA-approved drug that is similar in structure to heparan sulfate, successfully acted as decoy. Heparin is a widely used drug designed to treat blood clots. Since blood clots and strokes are common complications with COVID-19, many doctors already administer heparin to patients.The UCSD team demonstrated that the two approaches can block infection in lab-grown cells about 80 to 90 percent of the time.“Certainly in the laboratory you can demonstrate that it works, but to deploy it and use it as a therapeutic has not been demonstrated,” Esko said.The NIH noted that more studies are planned to explore whether heparin, heparan sulfate, or drugs that target heparan sulfate might yield a viable COVID-19 treatment.Dr. Esko said he’s already been in talks with companies that plan to use their study as a rationale for a clinical trial.“It is very humbling when you realize we’re working on a pandemic right now, and maybe what we’ve done can contribute to a treatment for the disease,” he said. 3038

SAN DIEGO (KGTV) — Teachers, grocery workers and police officers are among those slated to receive the COVID-19 vaccine in the next phase, but there is still debate about how best to prioritize those industries during the rollout.After the vaccine reaches individuals in Phase 1A, frontline healthcare workers and people in nursing homes, a CDC advisory panel recommended Sunday that Phase 1B consist of people aged 75 and up and certain high-risk essential workers.About 30 million essential workers fall into this category. Ultimately, it will be up to states and local health departments to determine which of those essential workers get first access to the lifesaving vaccines.“I feel like we're on an organ transplant committee deciding who gets the liver and gets to survive. It's a tough decision,” said Dr. Christian Ramers, a member of San Diego County’s vaccine advisory group.There is particular focus on when to vaccinate teachers. Nevada’s preliminary plan is to put teachers and transit workers ahead of food and retail workers. On the other hand, Louisiana’s plan is to vaccinate prison guards and food processing workers before teachers.“I really hate that idea that we are pitted against other essential workers,” said California Teachers Association president Toby Boyd.There are health and economic considerations surrounding the timing of immunizations for teachers. On one hand, there’s broad agreement that in-person learning offers superior educational and emotional outcomes for children, along with significant child care benefits for families.“It’s going to help economically because it will allow parents to go back into the workforce without worrying about their child,” Boyd said.On the other hand, education can happen virtually while jobs like policing, firefighting and food processing cannot. There are also questions about the relative risk of transmission in a classroom compared to other work settings.“[In] a school environment, you can basically control the environment with your policies, with your air conditioning system, with mandatory masking,” said Dr. Ramers. He said other industries, such as food handling, present more risk.“We want to stick really to who has the highest risk of catching the disease because of the constant exposure, and then who has the highest risk of dying of the disease? Those are really the two main driving principles that we're trying to balance,” he said.A group of scientific advisers to Governor Gavin Newsom met Monday to discuss the vaccine priority schedule.Last week, the governor’s vaccine advisory group suggested three industries should be considered for priority within Phase 1B: emergency services workers, food and agriculture workers, and education and child care employees.The task force noted the following specific jobs. 2819

SAN DIEGO (KGTV) -- The latest water main break Sunday in the Midway District is the latest example of San Diego’s aging water system. But the city is working to fix the issue, replacing more than 100 miles of water transmission and distribution pipes.According to city documents, since 2013, San Diego spent 8 million to repair and replace 116 miles of water transmission and distribution pipes.A total of 72 miles of those repairs were on cast iron pipes, the oldest ones in the system. The project started in 2007 and sparked a rate increase to pay for the work.RELATED: Water main break in Midway District causes flooding, shuts down roadAs older piper are replaced, the city has seen the number of water main breaks decrease. "We have more than 3,000 miles of pipeline," said department spokesperson Brent Eidson, "To do it properly, we're probably always going to be replacing pipes."Throughout the project, older pipes made from concrete or cast iron are being replaced with new PVC pipes. Edison says PVC is the industry standard. Pipes made from the material usually last between 50-75 years.The city says its water system extends more than 400 square miles and moves roughly 172 million gallons per day. Included in that area is 49 water pumping stations, 29 treated water storage facilities, three water treatment plants and more than 3,300 miles of pipelines.The city hopes to have all the cast iron distribution lines replaced by 2018-19. The goal is to have all the larger cast iron transmission mains replaced by 2023. Some of the cast iron pipes are nearly 100 years old.The following numbers were provided to 10News by the Public Utilities Department and list the number of breaks over the last six years.2012: 1022013: 952014: 742015: 632016: 852017: 81 (as of October 20)2018: 29 (as of August 5) 1841

SAN DIEGO (KGTV) - The California Department of Alcohol Beverage Control (ABC) made changes making it easier for businesses to sell alcohol.This week, the agency made major changes allowing restaurants to sell beer, wine and pre-mixed drinks or cocktails for pick-up or delivery as long as it is sold with food and has a secured top.While the changes will help many business owners, some San Diego bar owners say the ABC needs to take a look at other parts of the law as well."I know my seven employees are hurting, and I am too," said Tony Raso of Bar Sin Nombre.Raso said when the statewide order came down to close, he did. He has bar food he can sell, but where his problem comes in is with the beer that's already on tap."My struggle has been with all of the draft beer," he said. "We're primarily a draft house, and most of my money is in draft inventory."According to the ABC's website, restaurants "selling beer, wine, and pre-mixed drinks or cocktails for consumption off the licensed premises may do so when sold in conjunction with meals prepared for pick-up or delivery. Any such alcoholic beverages must be packaged in a container with a secure lid or cap and in a manner designed to prevent consumption without removal of the lid or cap."Raso said while he appreciates the relaxed restrictions, he's still sitting on at least ,000 in kegs he can't sell."Allow us to repackage the beer from the taps," Raso said. "Allow us to drain the inventory that we already have tapped that's going to spoil and allow us to create some sort of revenue."In a statement to 10News, a spokesperson for the ABC wrote 1623

SAN DIEGO (KGTV) -- The City of San Diego is working to transform Little Italy into an outdoor dining experience. They're streamlining the process for shops and restaurants to serve more customers while promoting social distancing under a new outdoor dining and shopping proposal.Marla Encinas had to close her Little Italy clothing boutique, Valmare, for two months. "We tried to do online selling but its definitely not the same," said Encinas. RELATED: Is 'Curbside Gaslamp' a preview of Fifth Ave.'s future?The store is back open now under new rules about cleaning, capacity and social distancing. But, for any business, fewer customers often means less revenue. The city of San Diego is trying to change that. On Thursday, Mayor Kevin Faulconer announced a proposal to waive fees and fast-track the permit process to bring restaurants and shops outdoors. "They’ll be allowed to maximize outdoor space to allow physical distancing and expand the number of customers they can serve," said Faulconer. RELATED: Gaslamp Quarter thoroughfare may become promenadeEncinas says her store is definitely on board. "I think its going to be really cool to be outside in the open air and be able to bring out our business," said Encinas. With approved permits, businesses can set up tables and chairs or racks of clothes and other items on sidewalks, streets, and parking lots. "I would love to do both jewelry and clothing," said Encinas. "I would love to bring out summer stuff because the weather is so nice, people are starting to slowly go out."Last Saturday, Little Italy had their first al-fresco dining event on India Street. By adding retail shops in the mix, more businesses will get a much-needed chance to bounce back from Covid-19. "It's going to be very fun," said Encinas. "You’re going to have a bunch of different vendors, it's going to be different than your typical shopping experience."Businesses can apply for the outdoor dining permits on the city's website. The proposal is going before city council for approval during the first week of July. 2066
