New stroke treatment moves toward clinical trials

first_img Source:http://www.ucr.edu/ Reviewed by James Ives, M.Psych. (Editor)May 10 2019A stroke treatment developed by researcher Byron Ford at the University of California, Riverside, has moved toward clinical trials.The treatment focuses on neuregulins, a family of naturally occurring proteins that has shown promise for treating stroke, a leading cause of death in the United States and the major cause of long-term disability.During stroke, blood supply to the brain is interrupted. Most often, an artery to the brain gets blocked by a clot or a blood vessel ruptures. With no blood — and therefore no oxygen or nutrients — reaching the brain, cells in the brain begin to die locally, at the “core,” within a couple of hours. Subsequently, the core cells burst and release their components into the surrounding area, which then experiences a dramatic inflammatory response. This area, called the ischemic penumbra, dies over the course of several hours or days. Neuregulin-1, or NRG-1, one of four proteins in the neuregulin family, prevents this inflammation and cell death.”Cells in the core die by getting overexcited and exploding,” said Ford, a professor of biomedical sciences at the UCR School of Medicine, whose company, Brain-Gen, has patents for the use of NRG-1 to treat stroke. “Cells in the ischemic penumbra die by committing suicide. This happens, we believe, to prevent the whole brain from dying. An analogy: imagine a grenade is flung into a crowded theater, and a few people throw themselves on the grenade. They will die, but due to their sacrifice, others may very likely be spared.”Brain-Gen is co-owned by his brother Gregory Ford, a neuroscientist and the dean of the College of Arts and Sciences at Fort Valley State University in Georgia. Byron Ford explained that Zensun Biotech, a Shanghai-based Chinese company with which Brain-Gen has recently partnered, has patents to use a particular form of neuregulin, called Neucardin, to treat heart failure. Zensun Biotech does not have patents, however, for Neucardin’s use in clinical trials for stroke. Brain-Gen tested Neucardin and found it works for stroke in animal models.The two companies have signed an agreement to collaboratively move Neucardin toward clinical trials for stroke and to form a joint venture. The new company plans to approach the Food and Drug Administration, or FDA, to expand the use of Neucardin for stroke and to explore the possibility of securing funding from the National Institutes of Health, or NIH, with the aim of joining its StrokeNet clinical trials program.Related StoriesStudy explores role of iron in over 900 diseasesNew approach to post-stroke rehabilitation proposedUse of statins linked to reduction of mortality risk in dementia patientsInvolving more than 200 hospitals in the country, StrokeNet conducts small and large clinical trials and research studies to advance acute stroke treatment, stroke prevention, and recovery and rehabilitation following a stroke.”To our advantage, Zensun has already completed phase I and phase II clinical trials for heart failure and shown that Neucardin is safe and improves heart function in patients,” Ford said. “A stroke is like a heart attack in the brain. If the FDA says we can cross-reference Zensun’s data for approval to treat stroke, this would greatly expedite matters as we apply to become part of the NIH StrokeNet.”Each year, nearly 800,000 Americans have a stroke, of which about 140,000 die. The “Stroke Belt,” an area in the southeastern United States and Mississippi Valley, has the highest rate of stroke mortality in the country.Currently, the only FDA-approved drug to treat stroke is tissue plasminogen activator, or t-PA, which melts the clot. It has no effect on brain cells, however, and can be used only within a three-hour window from the witnessed time of stroke onset, beyond which t-PA damages blood vessels and causes bleeding. Further, only 3%-5% of stroke patients qualify for t-PA due to the limited time window and access to primary stroke centers. In contrast, Neucardin can be given to a patient more than 12 hours after a stroke and has been shown to be safe in patients.Ford proposes that Neucardin be administered intravascularly to the patient along with t-PA to offer protection to the brain and potentially block t-PA’s negative effects that lead to bleeding in the brain.”Neucardin can possibly be delivered in an ambulatory setting due to its relatively safe profile,” he said. “It can be given to the patient even before it has been determined if a stroke took place. It can also be delivered days following stroke to stimulate repair and regeneration in the brain. All this significantly boosts our hope for treating stroke.”last_img read more

Florida city pays 600000 ransom to save computer records

first_img Citation: Florida city pays $600,000 ransom to save computer records (2019, June 19) retrieved 17 July 2019 from https://phys.org/news/2019-06-florida-city-ransom.html © 2019 The Associated Press. All rights reserved. The Riviera Beach City Council voted unanimously this week to pay the hackers’ demands, believing the Palm Beach suburb had no choice if it wanted to retrieve its records, which the hackers encrypted. The council already voted to spend almost $1 million on new computers and hardware after hackers captured the city’s system three weeks ago.The hackers apparently got into the city’s system when an employee clicked on an email link that allowed them to upload malware. Along with the encrypted records, the city had numerous problems including a disabled email system, employees and vendors being paid by check rather than direct deposit and 911 dispatchers being unable to enter calls into the computer. The city says there was no delay in response time.Spokeswoman Rose Anne Brown said Wednesday that the city of 35,000 residents has been working with outside security consultants, who recommended the ransom be paid. She conceded there are no guarantees that once the hackers received the money they will release the records. The payment is being covered by insurance. The FBI on its website says it “doesn’t support” paying off hackers, but Riviera Beach isn’t alone: many government agencies and businesses do.”We are relying on their (the consultants’) advice,” she said. The hackers demanded payment in the cryptocurrency bitcoin. While it is possible to trace bitcoins as they are spent, the owners of the accounts aren’t necessarily known, making it a favored payment method in ransomware attacks.Numerous governments and businesses have been hit in the United States and worldwide in recent years. Baltimore refused to pay hackers $76,000 after an attack last month. The U.S. government indicted two Iranians last year for allegedly unleashing more than 200 ransomware attacks, including against the cities of Atlanta and Newark, New Jersey. The men, who have not been arrested, received more than $6 million in payments and caused $30 million in damage to computer systems, federal prosecutors have said.The federal government last year also accused a North Korean programmer with the “WannaCry” attack that infected government, bank, factory and hospital computers in 150 countries. He is also believed to have stolen $81 million from a Bangladesh bank. He also remains in his home country.The FBI had no immediate comment Wednesday on the Riviera Beach attack.Tom Holt, a Michigan State University criminal justice professor, said hackers often attack common and known vulnerabilities in computer systems. He said organizations’ technology managers need to examine their systems for such flaws and teach their employees not to open suspicious email or click suspect links. The FBI says businesses also need to back up their data regularly on secure computers.Holt said most attacks originate outside the U.S., which makes them difficult to police. He said many victims wind up like Riviera Beach: They pay their attacker because it is likely the only way to retrieve lost data.”They might not pay the initial ransom that was suggested, but they may work with a third-party provider to negotiate the ransom down,” Holt said.He said in almost all cases, the attackers decrypt the computers after payment, allowing the victims to retrieve their data. He said the WannaCry attacks were an exception—the hackers took the money but often didn’t release the data.Some private WannaCry decryption attempts were successful.
