SAN DIEGO (KGTV) - The family of a man who was hit and killed by an Amtrak train Tuesday night is grieving and hoping he doesn't die in vain.Wentian He, 79, was walking across the train tracks toward the bus stop when he was hit and killed by an Amtrak train, according to his daughter Lilian Zheng. Zheng said her parents were on their way home from shopping.Wednesday, her mother was sobbing, saying she didn't want to live by herself.Zheng said her parents were married 54 years and she saw her dad as a healthy man, young and strong."He really enjoy[ed] learning the streets, the culture, how to behave in this foreign country. He worked really really hard," she said he was part of the Communist Army in China and it took him a while to get 'un-brainwashed'.Her parents emigrated to the U.S. in 2007 and she says they've been enjoying retirement, "They always together go out, they like to go to the senior center, because they can meet new people, they go to the flea market, or small shops so they can find unique stuff."Those trips, now cherished memories.Zheng hopes change can be made at the Washington Street station to protect people like her father. "The two tracks are so close they can cross, there is no [barrier] when Amtrak came, there should be a second gate," suggesting another barrier between the two sets of tracks."I feel life is so fragile, you know he's such a strong father and we've been depending on him," Zheng said tearfully, now they're leaning on each other.Zheng has a sister and niece in China. She hopes to bring her sister to the U.S., so they may fulfill her father's wish to show her the U.S., and bring his remains home to China. 1677

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) - The local protester who appeared in a controversial video getting taken away in an unmarked San Diego Police van is now speaking out, as police conduct an internal investigation.“No one should feel fear from the people that are supposed to serve and protect us,” Shayla Piccini told 10News on Monday as she shared the story of her arrest from last Thursday on Park Boulevard.The video shows a protester being taken away in an unmarked van as one officer warns her family around her not to follow them or he will shoot.“You see both of her legs kind of go up in the air because she's going [into the van] head first. That’s way too much force needed for this 20-year-old lady here,” said attorney Dante Pride.“That whole ride, I was asking several questions like, ‘Who are you? Where are you taking me?’ I was getting stares and no answers,” said Piccini.Piccini said she spent the day at a protest in Downtown San Diego. After several hours, the group was walking back to their car when she saw several police motorcycles driving past them. At that moment, she held up her cardboard sign.San Diego police say detectives witnessed her step off the sidewalk and swing the sign at a passing motorcycle officer, which she denied.In the foreground of the video, you can see men in what look to be marked police vests. But the people who handcuffed and detained Piccini in an unmarked van, are in plain clothes.One man wearing military-style tactical gear can be heard in the video saying, "You follow us, you will get shot. You understand me?"Piccini's cousin Brandi Matthews said she thought he was talking to her. “When he said the words, ‘I'll shoot you,’ I automatically just dropped to my knees to demonstrate that I'm not trying to hurt anybody...I just want to know where they're taking my cousin,” she added.According to San Diego Police, the statement about shooting those attempting to follow was made by a SWAT officer who had a pepper ball device. SDPD also told 10News that his comment was a valid announcement of use of force.Police said due to the large crowd still in the area, and the detectives felt the need to leave immediately.Piccini spent the night in jail on suspicion of assault on an officer. She has not been charged. SDPD’s internal investigation continues. 2307

SAN DIEGO (KGTV) - Swings and slides sit still across San Diego County, with caution tape wrapped around jungle gyms. Signs warning of coronavirus exposure tell hopeful parents and children the playgrounds they love are still closed.And no one seems to know when that will change."Kids do get infected with COVID, just like adults do," says Dr. Mark Sawyer, a Pediatric Infectious Disease Physician at Rady Children's Hospital."This is why we're worried about kids gathering because they potentially could get infected there and bring the infection home to more high-risk individuals who live in their house."Playgrounds have been closed since the start of the pandemic in March.ABC 10News reached out to San Diego County Officials to see if they have any guidelines in place. A spokesperson referred us to the State Reopening Guidelines.In hundreds of pages of reopening guidelines and plans, the word "playground" only comes up a handful of times. One is in the Industry Guidance for Campgrounds, RV Parks, and Outdoor Recreation. It advises campgrounds that "Playgrounds should also remain closed."Another time is in the State's new Blueprint Activity and Business Tiers for reopening. It specifies that Family Entertainment Centers can reopen Indoor Playgrounds at 50% capacity once their county reaches the Yellow or least restrictive tier.Parents and some lawmakers are growing frustrated at the lack of clarity for City and County-owned playgrounds at parks.On Tuesday, a group of two dozen state lawmakers sent a letter to Governor Gavin Newsom asking him to create clear guidelines for reopening. San Diego Mayor Kevin Faulconer tweeted his support for the letter.Doctors, however, urge caution."Playgrounds are gold mines for transmissions for other diseases," says Dr. Christian Ramers, an Infectious Disease Specialist at Family Health Centers of San Diego."Kids get runny noses. There's a lot of touching there. Kids are touching everything with their hands. So I think there's uncertainty."Still, studies show kids need outdoor physical activity. A recent report from the American Academy of Pediatrics reinforced guidelines that say kids 3-5 years old should get 3 hours of physical activity every day. Kids 6-17 need at least one hour."I really think kids should be able to play," says Dr. Jaime Friedman, a Pediatrician with Children's Primary Care Medical Group. She says small groups should be able to use playgrounds as long as they wipe down equipment and maintain social distancing."But, I think it would be hard to mandate that everybody has to do it in that way or make a schedule of who can be on the playground..."The important thing is that they need to make sure they're washing their hands, not touching their face, and if other kids show up, or other families show up, then you probably want to get out of there," Dr. Friedman says.There's also a mental health aspect to the debate, as studies show outdoor play helps kids avoid anxiety, depression, and negative feelings.Rady Child Psychologist Brent Crandal says it's up to parents to get creative with play and find other outdoor options."We can take advantage of all the spaces near playgrounds that seem to be open to the public," Dr. Crandal says. "There are hiking trails. There are beaches. There are a lot of outdoor areas to take advantage of."Many parents have decided to break the rules and let their kids use playgrounds anyway. Some playgrounds have added padlocks on swingsets and slides to enforce the rules.In the meantime, City and County leaders say they can't do anything until the state releases specific guidelines for playgrounds.Doctors say the best way to get playgrounds open again is to work towards eliminating the virus."The only way to control this is community-wide effort to follow the guidelines which are basically wearing a mask and staying away from other people," says Dr. Sawyer from Rady Children's Hospital. "If we do that, we're going to win this battle." 3984

SAN DIEGO (KGTV) - The California State University Chancellor said Friday the schools will not increase tuition for the 2018-2019 academic year, and demanded the state fund the system's critical needs.CSU Chancellor Timothy P. White said it was in the state’s best interest to fund the university’s critical needs supporting student access, achievement, and degree completion.“In light of California’s strong economy, California’s students and their families should not be saddled with additional financial burden to attain public higher education,” said White. “We will continue to make the case to lawmakers, who represent all Californians, that an educated citizenry should be at the top of the state’s highest priorities.”Last year, nearly 100,000 CSU students earned bachelor’s degrees and 20,000 earned graduate degrees.In November, the CSU budget request sought an increase of 3 million. The system considers its most pressing needs to be enrollment growth, a graduation initiative, increases for employee compensation, healthcare and retirement costs, facility operations and infrastructure requirements.Governor Brown’s budget proposal included an increase of .1 million.10News reached out to the CSU chancellor to find out how officials planned to compensate for the funding gap. A spokesman said it has made a case for more funding and will continue to do so, until the state budget is finalized in late June. Any financial decisions for the university system dealing with a potential funding shortage would happen in spring 2019.The Governor's Budget Spokesperson, H.D. Palmer, released a statement about the funding situation. 1658
