Study: Noise from cars, trains, and planes can lead to depression is a real health risk

Study: Noise from cars, trains, and planes can lead to depression is a real health risk  Berlin: Harder to avoid in cities but more than annoying, traffic noise is a real health risk, and experts now believe that regular exposure to traffic noise increases the risk of depression and anxiety disorders.  According to a study conducted by the German Environment Agency, if road, rail and aircraft noise increases around a person by 10 decibels, the risk of depression can rise by up to 4%, 5% and 11%, respectively.  For anxiety disorders, the risk increases by up to 3% (for road and train noise) and 15% (for aircraft noise).  The German Federal Center for Health Education said that the mental health of a person is not the only thing that can suffer from noise, but also his body.  Sleep quality declines and concentration problems occur, starting from 30 decibels A, which is a unit of measurement of sound power in relation to the human sense of hearing.  Above 60 decibel A, the risk of cardiovascular disease increases, and exposure to 85 decibel A noise—about the volume of a highway—can cause damage to the inner ear.  The German Environment Agency study shows that the risk of developing an anxiety disorder or depression almost doubles if people are awakened three or more times during the evening by train noise.  According to the World Health Organization, one in five Europeans is regularly exposed to evening noise levels that can lead to major health problems.         A medical science examination that stimulates the incidence of cancer : Dr. Alexander Myasnikov  Dr. Alexander Myasnikov announced that medical science knows many factors that stimulate cancer. So it must be remembered to prevent it.  And Myasnikov points out on a TV show that only 2 percent of all cancers are linked to exposure to X-rays. It explains why you should not repeat a CT scan.  According to him, when performing a CT scan, the patient receives a dose of radiation equivalent to the dose he receives when examining a chest x-ray daily for a whole year.  And he warns: "It is very dangerous for children, as 500 CT scans of the head stimulate the development of brain cancer. We must always remember that this is a strong stimulus for the development of tumors."  And he adds: the less resort to tomography, the better. Because the use of this examination should be only according to specific indications.         Starvation Slows Aging : Scientists Research  Studies prior to this study conclusively observed that calorie restriction can extend the lifespan of animals.  A new study has revealed that just the sensation of hunger can be enough to slow down aging and that even the taste and smell of food can reverse the benefits of a diet .  Previous studies have conclusively observed that calorie restriction can extend the lifespan of animals.  A new study published Thursday in the journal Science suggests that starvation alone can extend the lifespan of fruit flies.  Researchers from the University of Michigan in the US and others discovered in their research that bees were starved by removing amino acid molecules from their diet or by activating the part of their brain that motivates them to eat. Life span increased.  Study co-author Scott Pletcher said: 'We overcame the dietary nutritional theories that researchers had been working with for years to say that this (extending life through dietary control) was necessary. do not have.  Research has found that the concept of not overeating leads to benefits such as increased lifespan.  Scientists have created hunger in bees in several ways.  In one procedure , they varied the amount of branched-chain amino acid molecules (BCAAs) in a test snack food and then later allowed flies to freely eat a buffet of yeast or sugary foods.  The scientists found that the flies that received the low-BCAA snack ate more of the fermented food than the sweet one at the buffet, compared to the flies that received the high BCAAs.  The researchers explained that preference for yeast over sweets indicates a need-based appetite.  This behavior was not due to the calorie content of the low-BCAA snack, as the bees ate more food and gained more calories.  The researchers also found that when bees fed a diet low in BCAAs, they lived significantly longer than flies fed a diet high in BCAAs.  The scientists then activated nerve cells associated with hunger in the flies using red light.  Flies that undergo this process eat twice as much food as other flies.  These flies also lived significantly longer than the control flies.  Study co-author Christy Weaver said: 'We think we created a kind of insatiable appetite in the flies and by doing that the flies lived longer. '  Although the scientists used only flies in the study, they claim that 'there is every reason to expect that the mechanism discovered has the potential to increase appetite in other species.'  The researchers concluded in the study that ' the demonstration of appetite relaxation to extend lifespan suggests that stimulating conditions alone may be sufficient to induce aging.               A team of doctors in Canada is studying new hope to restore vision by activating dormant cells in the retina  SAN FRANCISCO: A team of doctors in Canada is studying the possibility of helping patients who have lost their sight due to degenerative diseases of the retina, by activating latent cells in the retina.  It is known that retinal degeneration is due to the loss of photosensitive cells that lie on the retina at the back of the eye. When these cells deteriorate due to various diseases, the eye cannot compensate them, and thus the patient's vision deteriorates until he eventually loses his sight completely.  According to the study, published in the Proceedings of the National Academy of Sciences, a research team from the University of Montreal is studying the possibility of activating underlying glial cells in the retina so that they can transform into new cells with photoreceptor-like characteristics, allowing patients to distinguish colors and even read and drive a car.  "We discovered that there are two genes that can convert latent cells known as Müller cells into retinal neurons," said lead study author Dr.  And she added, in statements reported by the “Medical Express” website, which specializes in medical research: “The interesting thing is that Müller cells can be activated and employed to regenerate the retina in fish, but things do not work this way in mammals, including humans, and it is not yet completely clear to us.” Why is that happening?  "Perhaps in the future we can take advantage of these cells that are found naturally in the retina, and activate them in order to produce retinal cells to replace the cells that were lost for pathological reasons, and thus restore sight again," Boudreau Pinsono said.
