Izvestia : A dentist reveals the age of modern dental fillings

Izvestia : A dentist reveals the age of modern dental fillings  Dr. Mikhail Azotyan, an expert in the field of dental innovations, announced that the lifespan of ceramic, metal and composite fillings is 5-15 years.  The expert says in an interview with the newspaper "Izvestia": "The age of innovative materials for dental treatment, such as ceramic, composite and metal fillings, can be different depending on the quality of the material, the quality of the composition and the proper care of the mouth. It usually ranges from 5 to 15 years or more. But it can be It can serve longer years if it is properly installed and the patient takes care of the health of his oral cavity.  According to him, dental implants can serve for decades and even a lifetime, if a person takes care of them and visits the dentist periodically. In addition, the new implants made of ceramic and titanium alloys have high durability, so they last much longer.  He says: “The development of digital technologies, including tomography, 3D scanning, modeling and virtual printing, allows dentists to plan and treat with high accuracy and efficiency. In addition, artificial intelligence and neural networks are beginning to be widely used in dentistry. This technology can be used To identify diseases in radiographs, dental implants, and monitor changes in the teeth and jaws, as well as to determine the treatment method specifically for each patient.  The doctor points out that new materials and technologies allow doctors to provide more durable and aesthetic services and treatment.            ScienceAlert : A 'new artificial system' that could help stop internal bleeding!  Blood clots are one of the most important natural defense systems in the body, a mechanism for bridging the internal and external gaps to keep us alive.  However, in cases where the body loses a lot of blood, the clotting process cannot continue. And this is where a new synthetic substitute could come in.  Researchers have developed a two-component system that targets internal injuries without causing any unwanted harm. The two components are compatible with the body's platelets (the cell fragments that lead to clotting) and fibrinogen (a protein that helps form clots).  So far, the synthetic process has only been tested on mice, but it effectively stimulated the blood-clotting part of the normal wound hemostasis reaction and proved to be much better at stopping bleeding than previous methods.  "The idea of ​​using two components allows for selective gelatinization where the concentration is enhanced in the wound, mimicking the final effect of the natural clotting cascade," says chemical engineer Bradley Olsen of the Massachusetts Institute of Technology (MIT). The first part of the system is a biocompatible polymeric nanoparticle called PEG-PLGA that is designed to bind platelets that can be spared by the body during infection. Platelets are drawn to the site of injury, which in turn carry these bound nanoparticles.  The second part of the system is a polymer that replaces fibrinogen and starts forming clumps through interaction with the nanoparticles. The team describes this second component as a crosslinker, essentially holding particles that have formed around the wound together.  Crucially, the researchers designed the particles in such a way that they can't accumulate where they shouldn't (in the wrong places, blood clots can also be dangerous to our health) by only getting them to entangle at a high enough concentration.  And in a small initial trial in mice, the artificial system not only proved highly effective, but also lasted longer than normal blood clots. Furthermore, the system did not trigger any unwanted immune system reactions in the animals.  "The idea is that with these two components circulating within the bloodstream if there is a wound site, the targeting component will start to accumulate at the wound site and also bind the crosslinker," says chemical engineer Celestine Hong of MIT. "And when both components are in a high concentration, you get a More crosslinking, and they start to form that glue and help with the clotting process."  Blood loss from traumatic events such as car accidents claims millions of lives every year. It is essential to stop the bleeding as quickly as possible, but with internal bleeding in particular, it can be difficult to determine what is happening and where.  This system will automatically target the problem site and provide some assistance to the body so that more comprehensive medical assistance can be provided. All that is needed is a syringe that first responders can provide.  With further testing, the researchers believe the system they have developed could help medical professionals locate internal bleeding more quickly and without expensive or complicated equipment.  "What was particularly remarkable about these results was the level of recovery from severe injury that we saw in animal studies," says chemical engineer Paula Hammond of the Massachusetts Institute of Technology. "By introducing two complementary regimens in sequence, it is possible to obtain much stronger clotting."  The research was published in Advanced Healthcare Materials.          "Superfoods" can boost our health and maintaining physical fitness, just like walking 4,000 steps a day  A study found that eating a certain healthy diet may be just as beneficial as walking an extra 4,000 steps a day for maintaining physical fitness.  Scientists say adding "superfoods" to the diet boosts physical fitness without any real exercise, as well as improves overall health. They believe this is because a nutritious diet improves metabolism, helping the body process calories and absorb good foods.  The reason that some people who exercise are fitter than others (who also exercise) may be because they are more strict about what they eat.  More than 2,000 participants had to run on a treadmill while their oxygen levels were measured by Harvard researchers.  People who adhered closely to a Mediterranean-style diet, consisting of plenty of fruits, vegetables and whole grains, had the same level of fitness as people who took about 4,000 steps per day in the researchers' previous studies.  Fruit and vegetables are high in fiber, which acts as a natural fat burner that can help boost your metabolism. It also contains a high percentage of antioxidants that prevent inflammation and other health problems.  “In middle-aged adults, healthy dietary patterns were strongly associated with physical fitness even after activity levels were taken into account,” said study author Dr. Michael Mey, of Harvard Beth Israel Deaconess Medical Center in Boston. “The improvement in fitness was similar to the effect of taking an extra 4,000 steps.” every day".  It is known that healthy diets reduce the risk of heart disease and cancer.  Dr. Mi's study used data from 2,380 middle-aged Americans. Participants completed a food frequency questionnaire to assess consumption of 126 items over the past year. The study compared the participants' physical fitness and diet quality.  The information was used to assess diet quality using the Alternative Healthy Eating Index (AHEI) on a scale of 1 to 110, and the Mediterranean Diet Score (MDS) on a scale of 0 to 25, both of which are related to heart health.

Dr. Mai added: "There are actually many healthy reasons to consume a high-quality diet, and we offer another reason why it relates to physical fitness. A Mediterranean-style diet with whole, fresh foods and minimal processed foods, red meat, and alcohol is a great place to start."           Dr. Alexander Myasnikov :  Warns of invisible carcinogens  According to Dr. Alexander Myasnikov, a person is exposed daily to substances that can undermine his health, including hidden carcinogenic substances that surround him in his daily life.  And Myasnikov points out in a television program that, according to doctors, carcinogens cause cancer, including chemicals used in homes, Teflon utensils, dyeing fish canned in oil, and of course cigarette smoke.  "Cigarette smoke contains about a thousand carcinogens," he says.  And he adds, the interesting thing is that nicotine is not among them. Smoke, ash and combustion particles are dangerous. This is also why coal causes lung cancer. By the way, the asbestos material used in construction causes the same disease.  He says: "A person can be exposed to the effect of carcinogens, but he does not attach importance to it."  He adds: Cancer is a complex problem, and for its development it needs several negative factors, and carcinogens are often among these factors.  Myasnikov warns that a high percentage of cancer is caused by food. Therefore, it is not recommended to cook food with Teflon utensils with a damaged coating. It is also not recommended to re-use oil for frying, and foods containing trans fats and fast carbohydrates that cause insulin sensitivity should be excluded.  “The gut microbiome is one of the main factors in the development of cancer,” he says. “When you take antibiotics, use enemas, and have a poor diet, the microbiome ‘goes crazy’.”  According to him, a healthy lifestyle stimulates the body's natural defenses.
