The human brain adapts to the loss of sensory information by using visual cues | Instant News


Researchers in the United Kingdom and the United States have found evidence in a new study that they can develop feelings of self even without touch.

Studies have shown that if adults lose their sense of touch and “proprioception” (ie, body posture) as adults, they may use visual cues and conscious thought or reasoning to move their bodies to learn compensatory skills.

However, people who have never had touch or proprioception can find faster, more unconscious ways to process visual cues to move and orient themselves.

A research team from the University of Birmingham conducted the study in collaboration with researchers from the University of Bournemouth and the University of Chicago, which was published in Experimental brain research.

The team worked with two people with unique sensory experiences, Ian and Kim: Ian lost touch and proprioception (body posture) at the bottom of the neck after autoimmune reaction to the disease, collectively called somatosensory. As a teenager. Kim had no somatic sensation when she was born and lacked the sensory nerve fibers needed to feel her body.

Researchers are interested in understanding how the human brain adapts to the loss of sensory information and how it would compensate for sensory information if it did not appear first.

There are many questions about how we form our sense of body and self. The body and the self are very integrated. When you close your eyes, you will have a sense of the physical self, but if there is no touch or proprioception, this will not be the case.

Kim’s vision, hearing and vestibular system are all in a special state. She had no touch or proprioception, nor did she. Ian’s situation is very different, because he has these senses and loses them. We are interested in whether a person can obtain visual information that does not involve visual perception and feed it into a certain location in the brain responsible for producing physical sensations. In essence, can you use it to make yourself feel physically when you see it? “

Peggy Mason, Professor of Neurobiology, University of Chicago

To conduct this research, Kim and Ian and age-matched control subjects entered the laboratory at the University of Birmingham and participated in many experiments designed to assess their physical and mental images and their unconscious feelings about themselves. The body in space. These include moving the cursor on the screen to locate landmarks such as fingertips and knuckles, and estimate the “reach” distance (length of the arm) to report the shape and size of the hand.

The study found that there are many similarities between Kim and Ian’s performance in the experiment, and interestingly, there are differences between them. For example, in the hand experiment, Jin’s estimate of the shape and size of her hand was close to that of the control group, which was wider and shorter than the actual hand, while Ian’s estimate was much more accurate.

Principal Investigator Chris Miall, Professor of Motor Neuroscience at the University of Birmingham, said: “We think the difference between Ian and Kim’s responses is related to the visual control they use to navigate the environment. For Ian, this is very important. A conscious process, He learned to use visual cues to continuously evaluate and monitor the environment. For Kim, the process is more unconscious. She still uses visual information, but in a more intuitive and intuitive way.”

The co-author of Jonathan Cole, a professor of clinical neurophysiology at Bournemouth University, added: “You and I are unconscious about the habits and skills, but Ian must always think about exercise.”

These results indicate that if adults lose touch and proprioception in adulthood, they may be able to use visual input and conscious thought to move their body, thereby learning compensatory skills. However, people who have never experienced somatic sensation may be able to develop mechanisms that bypass the lack of sensation and instead use unconsciously processed visual information for motor control.

Mason said: “What we can learn from this is that you may not behave like others, but you will find a way to make a body scheme.” “You will find a way to feel about yourself. Kim has found It’s not the way you or I do it, nor is it the way anyone on earth can do it, but it’s absolutely vital to have this feeling of self. You must be somewhere. We are not in a big bucket Brain!”

The drugmaker claims that Eli Lilly’s monoclonal antibody treatment prevents the spread of COVID-19 in nursing homes | Instant News


The drug maker Eli Lilly claims that a new antibody therapy can stop new infections and thus help fight the community spread of COVID-19 among residents and staff of nursing homes.

The company’s new drug bamlanivimab uses monoclonal antibodies to attack the coronavirus. A joint study conducted by the National Institutes of Health and Eli Lilly found that compared with the drugs given, the therapy can Placebo to reduce infections among nursing home residents by 80%. Among the nursing home staff who took the drug, the infection of the infected person was reduced by 60% Eli Lilly says.

The monoclonal antibody is Laboratory-produced moleculesSimilar to the body’s natural ability to resist infection, it can enhance or mimic the way the immune system attacks viruses or other invading cells.

Eli Lilly’s antibody therapy Receive emergency use authorization Treated by the U.S. Food and Drug Administration (FDA) for COVID-19 infection in less than two weeks before November Regeneron’s COVID-19 antibody mixture Obtained the same authorization. After Regeneron was diagnosed with COVID-19, he treated former President Donald Trump.

These latest findings indicate that Eli Lilly’s treatment methods can also effectively prevent infections. CNN reportAccording to the drug manufacturer, pannibizumab can also prevent symptomatic infections among residents infected with the virus.

Although the company said it plans to do so, it has not yet peer-reviewed or released the data from the bamlanivimab study.

Eli Lilly’s Chief Scientist, Dr. Daniel Skovronsky, said: “We are very satisfied with these positive results. These results show that baranibizumab can help prevent COVID-19, thereby greatly reducing Of the symptomatic diseases of nursing home residents (these people are the most vulnerable members of our society). Officials said in the company Press Releases Thursday.

The monoclonal antibody treatment used in Eli Lilly’s drugs immediately provides almost the same protection for the COVID-19 vaccine, although people’s immunity to the coronavirus does not last longer than the FDA-approved vaccine.

Dr. Sriratta Edupuangiti, a vaccine researcher at Emory University, said that after vaccination, it takes about six weeks for the human body to produce enough antibodies to fight the virus.

A new study about how Covid-19 can be spread through the air, even just to talk | Instant News


Washington (AFP): scientists have known for several months, the new coronavirus can be suspended in microdroplets excluded patients when they talk and breathe, but still there was no evidence that these tiny particles are infectious.

A new study conducted by researchers from the University of Nebraska, which was uploaded on the website of the medical working paper of this week showed, for the first time that SARS-cov-2 are taken from the microdroplets, which are defined as under the age of five microns, can replicate in the laboratory.

This strengthens the hypothesis that normal speak and breathe, not just coughing and sneezing, are responsible for the distribution of Covid-19-and that infectious doses of virus can overcome the distance a lot more than six feet (two meters) called the guiding principles of social distancing.

The results are still considered preliminary and has not yet appeared in a peer-reviewed journal, which will give more confidence to the methods developed by scientists.

The document was posted on the website medrxiv.org where the most advanced research during the pandemic was first published.

The same team wrote a paper in March showed that the virus remains in the air in the rooms of hospitalized Covid-19 patients, And this study will soon be published in the journal, according to the lead author.

“It’s actually quite difficult” to collect samples, said Joshua Santarpia, adjunct Professor at the University of Nebraska medical center ORP.

The team used a device the size of a cellular telephone for this purpose, but “concentrations are generally very low, your chances of recovery material small.”

Researchers took air samples from five rooms of bedridden patients, at the height of about a foot (30 centimeters) of the feet on my bed.

Patients were told that produces microdroplets, which become suspended in the air for several hours in what’s called “aerosols”, and some coughing.

The team managed to collect microdroplets as small as one micron in diameter.

Then they put the samples in the culture to get them to grow, to discover that three of the 18 samples tested were able to reproduce.

For Santarpia, this is proof that microdroplets that also travel much greater distances than large droplets, can infect people.

“It replicates in cell culture and therefore infectious,” said he.

The potential for transmission of coronavirus microdroplets were at some stage were incredible health authorities around the world.

Later, scientists started to change their opinion and admit it can be a challenge, which is the basis for the universal camouflage.

The world Health Organization was one of the last, changing his position, doing so on 7 July.

“I feel that the debate has become more political than scientific,” said Santarpia.

“I think that most scientists who work on infectious diseases agree that there likely is an air component, although we can argue about what size”.

Linsey Marr, a Professor at Virginia tech who is the leading expert on aerial transmission of viruses and was not involved in the study, said it was rare to get measuring the amount of virus present in the air.

“Based on what we know about other diseases and what we know so far about SARS-cov-2, I think we can assume that if the virus is infectious in aerosols, then we can be infected through inhalation,” said she. – AFP

The vast majority (82%) believe that Canada should rely less on trade with China: reasonable support of the government of Trudeau in China | Instant News


Toronto, Oregon, July 21, 2020 – Canadian public opinion on relations with China is subtle and not easy to reconcile with the views of hawks and doves. We are very uncomfortable with our level of dependence on trade with China and with the Chinese regulations on the management Board in Hong Kong. We also want Canada to stand up against Chinese government policy we disagree with, but are concerned about the possible consequences to Canada to do it.

The new Ipsos poll for global news, believes that eight out of ten Canadians (82%) agree (35% strongly/47% somewhat) Canada should reduce its dependence on trade with China and diversify into other countries. At the same time, only a minority believes that Canada can afford to stop trading with the Chinese at all: only 38% agree (12% strongly/26% somewhat) Canada should completely sever economic ties with China.

Moderate support for Trudeau in China

In General, most Canadians think we’re doing the best complex and highly charged political situation: six out of ten (62%) agree (9% strongly/53% somewhat) Canada is the right balance between cooperation with China and the protection of Canada’s interests, leaving 38% who disagree.

A little less to feel optimistic about the Trudeau government in our relations with China. While the majority (58%) agree (9% strongly/49% somewhat) the Prime Minister shall supervise the relationship with China, Well, many (42%) disagree (15% strongly/27% somewhat). Trudeau’s approach seems the most favorable in Canada (68%), Quebec (61%), Ontario (60%) and British Columbia (59%) and in Saskatchewan and Manitoba (50%) and Alberta (41%).

Standing with Hong Kong

Canadians benefit this country, very closely related to security and right standing with Hong Kong, three-quarters of Canadians (75%) agree (24% strongly/50% something) that Canada needs to do more to stand up against the Chinese government and to protect Hong Kong people against the recent cuts of its citizens freedoms. Support for this position rose to 81% among Canadians aged 35-54.

Taking a firm stance against China, Hong Kong is not considered without political risks. Canadians are split right down the middle on how best to approach bilateral relations, taking into account all the possible consequences. Half (49%) believe that Canada should be careful not to offend the Chinese government and the risk of further economic sanctions or other political reactions, while the other half (51%) disagree.

About the study

These are some of the results of an Ipsos survey conducted between July 8 and 10, 2020, on behalf of global news. For this study, a sample of 1,000 Canadians aged 18+ interviews online. Quotas and weighting were used to ensure that the composition of the sample reflects the canadian population according to the census parameters. The precision of Ipsos online polls is measured using a confidence interval. In this case, the poll is accurate to within ± 3.5 percentage points, 19 times out of 20, all Canadians aged 18+ polled. The confidence interval will be wider among the groups. All sample surveys and polls may be subject to other sources of error, including, but not limited to coverage error, and measurement error.
