According to surveys, men are much more careless about their health than women. The vast majority of the stronger sex (72%) does not see the point of having to worry in advance and undergo screening examinations – at least the three most important for men. Let’s see what kind of tests are these?
This test for blood testosterone, an ultrasound examination of the scrotum, as well as a PSA test – the same blood test that can detect prostate cancer in the early stages. The survey data give a complete picture of the state of the organs that are most important for men and their functions.
The production of male sex hormone testosterone is a constant value, unlike female sex hormones. By a certain age, testosterone levels begin to decline. This decrease can last from one month to several years, and with it the man’s well-being will worsen, as well as his character. Continue reading
Doctors, speaking of polypous rhinosinusitis (the disease is so correctly called), always mention a bunch of grapes. Like, polyps in the nose are very similar to her in shape. However, the similarity ends here: unlike grapes, polyps do not promise any pleasant sensations. On the contrary, they noticeably worsen the quality of life of the sick person with this ailment.
The main thing is not to miss the moment
Polyps are a benign tumor that begins to grow in the sinuses and descends into the nasal cavity, blocking the respiratory passage. This causes not only breathing problems, but also chronic fatigue, and sometimes even hearing loss. Unfortunately, “catching” the disease at its source is quite difficult. The formation of polyps is a process that can take several years. And at first, people simply do not attach importance to minor ailments like a mild runny nose and a slight stuffy nose. A doctor is usually consulted when more serious symptoms appear: Continue reading
Millions of microorganisms live in our body. And not all of them are peace-loving. How to recognize enemies invisible to the eyes, especially when it comes to pathogens of dangerous diseases? DNA level diagnostics come to the rescue. The results of the analysis can be found already 3-4 hours after treatment. For the invention of the polymerase chain reaction (PCR), which is based on the identification of the species of any living organism, the American scientist Carrie Mullys was awarded the Nobel Prize.
In the 70s of the twentieth century, enzymes were discovered that break down DNA at specific points. Researchers have the opportunity to “cut” DNA into shorter and more stable fragments.
After this, a new discovery followed: scientists “taught” DNA to copy itself and build to such sizes that it is easy to identify. In fact, this made it possible to identify any object of interest by the selected DNA fragment: here is the DNA of the common cold pathogen, this is staphylococcus, this is the herpes virus.
