Help diagnose diseases but 1st a look back in time. You noted of in she was an amazing anatomist who did about 30 cadavers and created exquisite drawings of what he found the discovery of x. Rays allow doctors to look inside our living bodies without cutting us open. Ultrasound further change diagnostic methods now scans of various kinds connected to computers are generating lots of data so much that its getting hard for radiologists to process alone Artificial Intelligence can help. Here at s N University Hospital about a 1000 patients have radiological exams every day. Were giving you a small dose of contrast agent. This results in countless images that have to be evaluated for that doctors depend on High Powered Computers and. Increasingly on Artificial Intelligence the walking on gets what we need tools because theres simply more data. Day photographed one hand and that wasnt much data of course its exploded today. Actually the computer doesnt even look at the images it looks at all the ones and zeros that make up the images. And the computers can infer a lot more information from High Resolution m. R. I. And c. T. Images than humans can do to recognize the abnormal patterns that indicate disease in the fine gradations of great tones radiologists need years of training and the most concentration heres how the human brain accomplishes this task are billions of nerve cells are constantly forming new connections in the brain and breaking down others this is how we learn and how patterns are impressed upon our minds so that we recognize them. The problem is that the more data the brain has to process the faster it tires out and supposed to look at thousands of images and even as a non radiologist you can guess that a finding will slip by you because youre tired that doesnt happen to a computer and we have extremely large quantities of data to analyze it well you need computer power. Or computer pole after all computer programs are superior to human beings when it comes to recognizing patterns but 1st the computer needs a kind of basic training its presented with a certain pattern then it compares all other patterns with this template and decides does the pattern match or not. Programs that recognize patterns have been used in the field of radiology for years foresting now wants to deploy Artificial Intelligence to help detect damaged brain tissue. This is a. Patient who had an acute distress and an expert sees that this c. T. Here is not entirely normal this is a war that requires years of training or and if we analyze the images with ai then it highlights this area showing that a stroke has occurred here with this weight radiologists dont look at several strokes a day like we do you can at least use this as an aide. Who submitted whether they accept the suggestions is something they have to decide for themselves or so im in. Charge Artificial Intelligence or a. I. Goes beyond mere pattern recognition the aim is to imitate the way the human brain works using Software Artificial neurons are connected with each other in layers and fed with an algorithm a sequence of instructions. The task here is to recognize a circle at 1st images of various shapes are fed into the system. During the learning phase a human tells the system whether it correctly recognize the image or not the system changes the connections between the artificial neurons accordingly. The ones that lead to the correct result get stronger those that led to the incorrect result get weaker thats how Artificial Intelligence learns youre seeing something here that no one else in the world can see ready only here its an absolute world fust. Thing and his team are trying to further improve the skills of their ai system. The scene the program is still in the learning phase. And its much more years in human form what we have here is an earlier exam the current exam we see these white stripes that we didnt have here before it all so thats new is not deceived as a radiologist i can see it very well now i can work through the entire finding from top to bottom you know. But what sima does this help me by color coding the differences between before and after you know the newest changes are shown an orange to visualize it while the previous image is marked in blue at. The old or new images exactly on top of each other and makes every difference visible for example whether a tumor has grown but thats not all. In the background the Artificial Intelligence system calls up similar images findings and treatment recommendations from medical databases and textbooks dr ai is much faster and more systematic than a human being could ever be this way it provides radiologists with crucial advice on diagnostics and treatment becoming a 15. Second look at different images of this disease that have been confirmed and compare them. And i also have the patients clinical information as well as clinical information thats typical for this disease. To persistent. Learn successfully programs like ciena need clear exemplary images and diagnosis after all ai will only get smarter if doctors and programmers provide it with good days. Since i dont think it makes any sense for me as a dog aim to be at best a mediocre. Or for an i. T. Person to take up doctoring as a hobby but each of us should play in the Champions League of our own disciplines to conceive. Forcing is convinced that in future more and more of the growing flood of data in radiology will be prescreened by dr ai decisions about diagnosis and treatments however will remain in the hands of human doctors for the time being. On the one hand medicine is becoming ever more high tech and complex using ai which. Reality and robots. On the other hand many patients when therapy is they consider a natural or authentic nature also provides of all materials for academic myths and if you are in mexico has a question about that. What is nature based on natural profit medicine. For one thing its at the root of modern university and science based medicine busy. The majority of modern pharmaceuticals are derived from plants. Plants have been used for medicinal purposes for 5000 of years both. Traditional healers use a range of leaves flowers fruits roots and bark. Use in some parts of south america teammate with the bark of the said rio tree is used as a painkiller candle rossa leaves combat headaches and in parts of africa the bark of the african cherry is used to treat a wide range of ailments. The worlds tropical rain forests are rich in plants with known medical properties. A lot of research is going into identifying the active substances in them and into identifying other species that might yield substances of medicinal value. Some substances used in certain systems of Traditional Medicine are actually toxins but appear to have therapeutic effect if the dosage is right typically small. Terms such as nature based on Natural Medicine can also denote something quite different namely the farrah puting effect of exposure to make your own Natural Forces sunlight. Fresh air. Water a german tradition of hyper affair appeal named after sebastien connived focuses on the stimulatory effects of cold water. Of course diet has an impact on health as well. And then theres traditional chinese medicine. The term Natural Medicine covers a wide range of traditions of substances and therapies some of these are called complementary therapies where there are accepted by conventional science based medicine as possibly helpful to treat symptoms or side effects. Of all plant families 12 in particular contain an amazing wealth of logistical flounce the mowbray family is the single greatest source science is just adding with the mulberry leaves can lower blood sugar levels in diabetes patients. Chance in the dr and family healed substances that could treat cancer and anticoagulants are found in some members of the legume family. There are so many plants with medicinal potential research is underway to find out how and whether they work. Its knowledge that dates back thousands of years the healing effects of plants and herbs knowledge that was hugely important in the middle ages but then to some extent forgotten. Many scientists are now developing a curiosity for these plants and medical practitioners are rediscovering their healing powers. German herbs expert islas fun put kama knows the healing potential of domestic plants here shes gathering herbs for medicinal teas some of the plan is. Like metals and birch leaves because they flush out the urinary system and black berry leaves have an antiinflammatory effect in the mouth. I use all 3 to make an herb and its like a home pharmacy. To protect themselves against pests and pathogens herbs often can. Oils bitter substances and acids that kill germs like willows along with many other active ingredients their bark contains salicylic acid compounds at the end of the 1900 century chemists develop these substances into one of the most popular fever and pain relief medicines aspirin. More than a 1000 herbal medicinal products are licensed in germany and new ones are constantly being discovered around the world many are still not well understood and research are underway as hens it is trying to unlock their secrets is investigating marshmallow root and cats whiskers which contain substances that may help relieve coughs and urinary Tract Infections the researchers goal is to develop new drugs and improve available once. The problem is the sheer multitude of substances in these Medicinal Plants often we know the plant has an effect except that many times we tell it which of the countless substances is responsible or if thats what our research is about cracking this code so we can develop more effective medications to come and begin to turn. Red sage is also an intriguing plant its known to have a wound healing effect but they are over 50 potential active ingredients so which one is responsible for healing wounds researchers are trying to find answers using human skin cell cultures they treat them each with a single isolated substance from the sage plant the question is does this substance promote cell production because for a womb to heal new skin cells have to grow in that area. The samples are tested a few days later. Its detailed and time consuming more but the results could be significant. There. It would be such a great breakthrough to identify which substances have the most positive wound healing effect rico pretty big especially for bedridden patients we use that are hard to treat hopefully our research will help us to develop new drugs. They havent tested all the substances yet but they hope to find the active ingredient within a year or 2 and then develop a drug from it. The research is further along for other Medicinal Plants. Mike downa at the s. And mehta clinic in western germany treats patients every day with highly effective herbal drugs. The clinic uses more than 50 plant based medicines in the internal Medicine Department alone and that for 15 years now. Supplementing conventional medicine with herbal remedies can offer big results. Like for nonspecific back pain and ailment many people suffer from because a 4 to one is nonspecific back pain can be greatly helped by using herbal medicine the biggest advantage of these horrible drugs is that they often cause fewer side effects significantly fewer its album edison also plays a major role in treating respiratory diseases it can alleviate the symptoms which means less coughing less pain in the limbs and foster healing and theres no conventional alternative to this herbal remedy thats on a par in terms of side effects a lot so once again the defense team is. Of course its always important to speak to a doctor about the potential causes of an illness and the treatment plan self medicating with herbal remedies alone could be life threatening its a danger that either one put comma is aware of her Medicinal Plants are considered safe but when she has a condition that doesnt respond quickly to an herbal treatment she consults a doctor. If outlet is right why im glad im here. Ok to get to you have a science question that youve always wanted answered it and were happy to help out and send it to us as a video text ovoid smell if we answer it on the show well send you a little surprise as a thank you can i just ask.

But home board continued his explorations eager to study those people whose culture and way of life had remained completely untouched by the spanish conquest.

More than 70000 are believed to live in the Amazon Region today. There once war your people lebanon anarchic society split up into small communities. Some clans still waged war on each other but their daily lives in the rain forest are primarily focused on on and working their small gardens for which the women are responsible. Them both was fascinated by the traditional lifestyle of the Indigenous Peoples as he traveled through the rain forest observing their customs and learning their languages in contrast to other explorers and researchers from europe who considered them to be savages he saw them as a group of people unspoiled by civilization but todays civilization is encroaching on the rain forest and its inhabitants to you or your car grew up in the arch of our community before leaving to go to college in the city a 15 day walk from here hes one of the few want you are to have regular contact with the outside world when i was very young snow and us old i always respect the nature.
