According to research published in the Proceedings of the American Academy of Sciences on May 14, the virus named Porcine deltacoronavirus (PDCoV) was recently discovered in pigs capable of “attacking” human cells and many other experimental animals.
This information raises concerns about the risk of disease outbreaks that threaten the health of humans and animals.
Scott Kenney, lead researcher at Ohio State University, stressed that the risk of spreading the virus from one species to another largely depends on the ability of the virus to reach human or animal receptors. Once they reach these receptors, the virus can easily penetrate the cell and infect the host.
Viruses can easily penetrate cells and spread disease to hosts.
Through the concentration of specific cell receptor analysis of the aminopeptidase N intestinal enzyme in the laboratory, the team found PDCoV can attack these receptors in the respiratory and digestive systems of not only pigs, cats and chickens that even people.
The research team at Ohio State University and the Dutch University of Utrecht has only identified the potential of spreading PDCoV among animals and volunteers participating in a cell transplant experiment containing PDCoV. The group is continuing to investigate the risk of transmitting PDCoV among species, in order to determine whether the strain is replicated in cells that they attack and transmit from pigs to chickens, even to humans. or not.
The latest finding of the PDCoV research group is making animal health and veterinary experts extremely concerned, because the virus has similar characteristics to virus strains that threaten human and animal lives. SARS (Acute Respiratory Syndrome) and MERS (Middle East Respiratory Syndrome).
Porcine deltacoronavirus was first found in 2012 on pigs in China, but did not record outbreaks. In 2014, the virus first appeared in the United States in an outbreak of diarrhea in pigs in Ohio state.
So far, more countries have discovered this strain. Young pigs infected with Porcine deltacoronavirus have symptoms of diarrhea and vomiting. However, the world has not recorded any cases in people infected with this virus.
Is there a drug “neutralizing” the harmful effects of alcohol?
After jubilant drinks, what is the thing that scares you the most? It is the headaches like hammering and the feeling of dry throat.
Yunfeng Lu, a professor of chemical engineering at the University of California, Los Angeles, USA (and claiming to be an alcoholic), is trying to find solutions to the negative effects of alcohol. And tests in experimental mice are showing very promising results.
Scientists are looking to minimize the negative effects of alcohol on the human body
The tablet Lu studied contained natural enzymes commonly found in liver cells, helping the body process alcohol faster.
It not only helps to relieve headaches such as hammering and dry throats but can also be used to treat alcohol poisoning.
To test the drug, Professor Lu and his colleagues first made a lot of drunken mice. Then they treat them. Result? Blood levels in these mice were reduced by 45% within 4 hours compared to untreated children.
Of course, mice rarely complain about excessive headaches, but Lu found that acetaldehyde levels – a toxic compound that causes cancer, causes headaches and vomiting, causing people to blush after Drinking alcohol and being produced during normal alcohol metabolism – remains extremely low.
However, Professor Lu’s advice is “Don’t get drunk”. His research aims to help hospitals, not to promote the “weekend warriors”.
Professor Lu and his team are checking to make sure there are no dangerous side effects from this treatment. If that goes well, human trials will begin in about a year.
Preventing headaches due to cup drinking is a lucrative business for some companies. In some places there are even drinks, costumes and even alcohol that do not cause headaches. Even so, the results of all this are still controversial.
