Researchers have developed a self-contained fiber-optic sensor for a smartphone that can be used for various biomolecular tests, for example, to determine pregnancy or control blood sugar levels. Sensor data can be decrypted using an application on a smartphone that will provide real-time results.Scientists at the University of Hannover said that with proper use of the sensor, smartphone users will be able to monitor blood, urine, saliva, sweat and breathing.
The sensor applies the optical resonance effect of surface plasmons, which occurs when light drives electrons on a thin film. Thus, the composition of the liquid, the presence of special biomolecules and microgas residues are determined.
One of the inventors, Court Bremer, said that it is possible to develop a built-in chip for smartphones. Thus, plasma resonance sensors can become widespread.
Using medical applications, the sensor data can be combined with the signal of the global navigation system of the smartphone. Then the user is sent to the nearest pharmacy, hospital or clinic.
Resonance of surface plasmons is a phenomenon that is usually used in biosensor analyzes, for which extensive lab equipment, a light sensor and a light source are required.
The life of a modern man is full of stress. Stressful situations lie in wait for us constantly and, as it turned out, provoke the development of many serious diseases, one of which is diabetes mellitus. How is the state of stress interrelated and diabetes mellitus? How to control yourself and prevent diabetes?
Strictly speaking, the most important role in the development of diabetes belongs to a hereditary predisposition. Scientists have proved this statement with the help of a study of twins. According to statistics, if one of them develops type 2 diabetes, then in the second twin, this disease occurs with a probability of 90%. For type 1 diabetes, the likelihood of the disease is somewhat lower, it is 50%.
However, the presence of an inherited predisposition to diabetes is not a sentence, because for the development of this disease requires the impact of a number of factors.
To provoke diabetes mellitus can:
- infections and serious illnesses;
- Presence of excess weight;
- sedentary lifestyle and malnutrition;
- elderly age;
Scientists have established that the carriers of the gene responsible for the likely development of diabetes are many people, more precisely, every fifth inhabitant of our planet. However, about 4% of the population is ill under the influence of various factors. The most common among them – obesity and excess weight, then go arterial hypertension, malnutrition, sedentary lifestyle, stressful situations.
Why does the state of stress stimulate diabetes?
For those who have a hereditary predisposition to diabetes, stress plays a very important role in the development of this disease. The state of stress can trigger the onset of diabetes mellitus of both the first and second types. And for those who already have diabetes, stress can become a factor that exacerbates the disease and leads to the development of complications.
For what reason do stressful conditions affect our bodies?
It turns out that in stressful, stressful moments, the so-called stress hormones begin to be actively developed: cortisol and adrenaline. These substances provoke an increase in the level of sugar in the blood, so that the body at the right time was provided with sufficient energy and the person could react in a timely manner to the situation.
When the danger passes, it is necessary to normalize the blood sugar level. For this, compensatory mechanisms are provided in our body. However, in diabetics they either do not work, or are too weak. In addition, we often have to endure chronic stress. Because of minor troubles and anxieties, we often remain in tension, and our blood glucose level rises. So the result of stress can be many complications:
- diseases of the cardiovascular system;
- impaired kidney function;
- leg diseases;
To all the rest, the state of stress significantly depresses our immune system. And we often forget about appointments of doctors, proper nutrition and exercise during intense moments, and this only aggravates the problem.
How to control stress
To exclude from their lives stressful situations is completely impossible, but to control stress and thereby eliminate the diabetes-triggering factor can be.
To do this, you need to determine what the impact of stress on the level of sugar. Try to measure the sugar level every time after a stressful situation. Compare the results with the level of tension in other conditions.
In addition, it is worth trying to determine what the effect on your body of various relaxation techniques. To do this, also make measurements of the sugar level every time, so you can find the best way to relieve stress. To control stress, use the most optimal and effective methods.
How to relieve stress?
There are both physiological and psychological approaches to stress management. In the fight against stress your assistants are an active way of life and the ability to “release to freedom” their emotions, rather than accumulate them in themselves.
- Try to perform exercises based on alternating tension and muscle relaxation.
- Do meditation or yoga.
- Most types of physical activity also contribute to lowering the level of sugar and help to cope with stressful situations.
- You can choose a relaxing hobby.
- Try to analyze your condition and learn to be free from excessive emotions.
Those who have to live with diabetes and who have a predisposition to this disease, experts advise you to remember about a healthy lifestyle and learn to relate to the surrounding world positively. Thanks to this vital position, diabetics can mitigate the manifestations of the disease and prevent complications.
