SAN DIEGO (KGTV) – The Marine Corps Air Station Miramar said a suspicious letter received by the post office was found not to contain anything harmful Tuesday.MCAS originally sent out a tweet stating that the post office identified a letter around 1:45 that was determined to be suspicious.First responders were called and took “appropriate actions.” Just after 4:30 p.m. MCAS tweeted that the parcel was screened and did not contain anything harmful.MCAS added that the post office is expected to resume normal operations Wednesday.#Update: The parcel was screened and did not contain anything harmful. The @MCASMiramarCA Post Office will resume normal operations tomorrow.— MCAS Miramar (@MCASMiramarCA) March 7, 2018 727

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 City of San Diego is taking legal action against the owners, operator and property manager of a independent living facility with squalid living conditions.Ten people lived in the now-closed home on Ewing Street near San Diego State, most of them elderly. Photos from inside the home show mold on mattresses, rat feces, holes in the walls, and overflowing trash cans.The City Attorney's office says fumes from an illegally installed water heater contaminated the interior, and the conditions were so dirty that a man's foot had to be amputated after a sore got infected. RELATED: Residents complain of bedbugs at El Cajon independent living facility"The mattresses are filled with bed bugs, there are mice droppings, it's awful," City Attorney Mara Elliott said. Independent Living Facilities are unlicensed and unregulated. They are often a last chance for vulnerable people to avoid becoming homeless - paying rent with social security or disability checks. Elliott's office is suing the owners, property manager, and operator, who could be forced to pay up to million. Additionally, operator Mark Rogers is being charged with 22 misdemeanors. Rogers also owns an independent living facility in El Cajon, where a tenant was murdered with a frying pan late last year. RELATED: Man charged with elder abuse for operating 'squalid' home in College AreaThe home on Ewing is known to police, who have responded to 300 calls over the last six years, mostly for disturbing the peace, suicide threats, and psychiatric evaluations.At least one person is still living inside. Morgan Cherry, who lives next door, said the home has a reputation in the neighborhood, but that the pictures took it to a new level. "I had no idea how bad it was," she said. Rogers said he is no longer operating the home. His attorney declined comment Thursday. 1865

SAN DIEGO (KGTV) - The FBI’s Violent Task Crimes Force asked for the public’s help Monday to find a man known as the “Burgundy Bandit” and wanted for nine robberies in San Diego, La Mesa, and El Cajon.In each robbery, the man entered the business and approached an employee, flashing a gun hidden in his waistband, the FBI said in a news release.The man demanded money and walked away. On several occasions, the man cased the business five minutes before the hold-up, officials said.Robbery locations include:June 27: Fred Loya Insurance, El Cajon 555

SAN DIEGO (KGTV) – Tens of thousands of jobs are on the line as Congress struggles to save the airline industry, but a new bill announced Friday is giving some aviation workers hope.For Dante Harris, it’s more than a job.“It's a career that I would never want to exchange for any other,” said Harris.In his 21 years as a flight attendant with United Airlines, he’s traveled to every corner of the world. Now, he’s among the tens of thousands laid off after Congress failed to pass a stimulus bill this weekHarris is the president of the Association of Flight Attendants-CWA Council 12 union stationed at LAX, which also serves San Diego and Seattle members.He says about 2,500 United Airlines workers on the west coast lost their income and health care.It comes as an incredibly hard blow for the first responders of the sky who already faced countless challenges due to COVID-19.“We provide service to make sure that doctors and nurses get to where they need to go, to make sure that Americans are safe,” said Harris.On Friday, House Speaker Nancy Pelosi said if a bipartisan agreement is not reached, she’ll push for a standalone bill to extend payroll protections for airline workers for another six months.Harris is calling on Washington to extend that crucial funding so airline workers can get their wings back.“We need that bridge to get us to the point where we can bounce back,” said Harris. “And we can fly America to all corners of the earth again.” 1468
