SAN DIEGO (KGTV) — UC San Diego researchers are testing a technology that's been in development for more than a decade to fight the coronavirus.In lab experiments, "nanosponges" covered in human lung cell membranes and immune cell membranes were found to attract and neutralize the SARS-CoV-2 virus in cell culture, according to a UCSD release. This caused the virus to lose about 90% of infectivity, or its ability to hijack cells and reproduce.The tiny sponges are designed to impersonate and protect healthy cells by soaking up harmful pathogens and toxins, according to Liangfang Zhang, a nanoengineering professor at the UC San Diego Jacobs School of Engineering.

This prevent the virus from then entering an actual human cell."Traditionally, drug developers for infectious diseases dive deep on the details of the pathogen in order to find druggable targets. Our approach is different. We only need to know what the target cells are. And then we aim to protect the targets by creating biomimetic decoys," said Zhang.While Zhang has spent the last 10 years developing the technology, his lab turned to using the nano-particle to fight the coronavirus when the pandemic hit.RELATED: Scripps Research's antibodies study shows signs of success against coronavirusNow, the first data on the technology's ability to battle the virus is being released after testing by researchers at Boston University."Another interesting aspect of our approach is that even as SARS-CoV-2 mutates, as long as the virus can still invade the cells we are mimicking, our nanosponge approach should still work. I’m not sure this can be said for some of the vaccines and therapeutics that are currently being developed," said Zhang.UCSD researchers will test the nanosponges’ effectiveness in animal models in the next few months and are moving as fast as possible to eventually test the technology in humans.

"If a virus comes, it could be blocked if there are nanosponges waiting for it."(Read more about the study and nanosponges here.) 2562

SAN DIEGO (KGTV) -- Two horses died Sunday after being seriously injured during separate races at the Del Mar Racetrack.A third horse was also hospitalized with an injury.The track tweeted at 2:17 p.m. confirming that in Sunday's third race, Ghost Street suffered a "catastrophic injury to his left front sesamoid and was humanely euthanized."Ghost Street was a 3-year-old gelding.A short while later, Prayer Warrior, a 3-year-old colt, was euthanized after suffering an injury to his front leg in Sunday's sixth race. 527

SAN DIEGO (KGTV) - In honor of Veterans Day, dozens of volunteers found a way to give back to current active duty military service members.The organization Waves of Appreciation packed thousands of "Appreciation bags" filled with snacks for service members traveling through San Diego during the holidays.Volunteers fill the bags assembly line style. This program started in 2011 when the founder of the event saw a military service member traveling alone during the holidays, exhausted and hungry. Since then volunteers have handed out more than 24,000 bags.Waves of Appreciation is looking for volunteers to pass out the goodie bags at Lindbergh Field in December in time for the holidays.

SAN DIEGO (KGTV) - Two more migrants were diagnosed with the flu in the county shelter downtown and one was sent to the hospital, according to Jose Alvarez Communications Specialist with the County of San Diego Communications Office.The flights have been landing at Lindbergh Field since May 14th, easing overcrowding in Texas detention centers.Border Patrol officials stated migrants are given a health screening in Texas before they travel to San Diego, and are screened again once they land.County Health officials stated a total of 31 migrants have been diagnosed with the flu since May 19, officials say. Twenty-seven migrants, 13 families, are currently quarantined.RELATED: County responds to flu outbreak at shelter, linked to Texas migrants flown to San Diego"This is a new situation to us and I'm told it could get much worse," County Supervisor Dianne Jacob said.Once off the plane, the migrants who crossed illegally in Texas and flown to San Diego are taken to a Border Patrol Facility to be processed by ICE.Eventually, they end up at the shelter. There they get another health screening and starting Thursday, everyone gets a mask and Tamiflu pill as a precaution to keep the sickness from spreading. The pill and a flu shot is offered to staff and volunteers at the shelter.As of Friday, extra nurses are coming into the shelter to check on the group and ensure no one else has come down with the flu.Those who are diagnosed go with their families to a hotel that has individual air units, so they don't spread the virus. They are educated on why they should stay in the room and, if they leave, what precautions to take so they don't infect others.Migrants in the shelter can come and go as they wish.Border Patrol stated migrants who exhibit flu-like symptoms are not allowed to fly and instead are given medical treatment in Texas. Border Patrol also said agents closely monitor detainees throughout the trip.The state dedicates ,000,000 to migrant shelters, according to County Supervisor Nathan Fletcher's Office. 2045

SAN DIEGO (KGTV) -- We know the importance of wearing a mask to protect the nose and mouth from the novel coronavirus, but some new research is raising questions about whether the general public should wear goggles, glasses or a shield to protect their eyes.The CDC already urges healthcare workers to wear eye protection. The agency updated its guidance in July, encouraging even healthcare workers in low-transmission environments to wear eye protection when it was previously listed as “optional.”Experts think the nose is still the main entry point for the virus because of the mechanics of breathing, but the surface of the eye is lined with the same mucous membrane to which the virus likes to bind.Animal studies have shown SARS-CoV-2, the virus that causes COVID-19, can enter through the eyes and there have been viral particles detected in human tears, but there’s no clear-cut data so far showing the eyes are a major entry point, said ophthalmologist Dr. Annie Nguyen at the USC Roski Eye Institute.However, some observational studies have suggested protecting the eyes may lower the risk of infection.In June, a study in the Journal Lancet suggested face shields, goggles and glasses could lower the risk of infection from 16 percent to 6 percent.Another study published this month suggests that simply wearing eyeglasses could help.Researchers examined 276 hospitalized patients in Suizhou, China. Based on trends in that region, they expected about 31 percent of the patients would wear eyeglasses. Instead, just 5 percent of the hospitalized patients wore glasses.The researchers noted the observational study had limitations, but theorized that eyeglasses may offer a protective barrier against the virus.“I wouldn’t be quick to make the recommendation for everyone to run out and wear glasses,” Dr. Nguyen said.An editorial published alongside the eyeglasses study urged caution. “Although it is tempting to conclude from this study that everyone should wear eyeglasses, goggles, or a face shield in public to protect their eyes and themselves from COVID-19, from an epidemiological perspective, we must be careful to avoid inferring a causal relationship from a single observational study,” wrote Dr. Lisa Maragakis at Johns Hopkins University School of Medicine.Experts say more evidence is needed because urging people to wear eye protection could have harmful side effects, like causing the wearer to inadvertently touch their face more frequently.“If there is additional evidence that builds up, then that’s the point that we change guidelines,” said Dr. Christian Ramers of Family Health Centers of San Diego.“People have had whiplash from things changing and going back and forth,” he added, citing the change in guidelines on face coverings.Still, some experts say people with underlying conditions should consider adding eye protection, as long as they’re careful not to touch their face.Doctors have suggested that people who wear contact lenses might want to switch to eyeglasses to cut down on the number of times they touch their eyes, but Dr. Nguyen said there’s no hard data yet showing contact lens-wearers are at greater risk from the virus. 3184
