Biomechanics of the masticatory muscles in correlation with teeth have been researched. Specific measurement models and special measurement methods have been used to simplify the complexity of the human chewing process. Here the function of the masseter muscle and the lateral pterygoid muscle as the key muscles in human masticatory system has been evaluated. A three-dimensional scan of a realistic...

Oxidative stress is defined as a disruption of the balance between production of reactive oxygen species and the body's ability to fight them off. They contribute to many autoimmune diseases, which have in the past been treated with anti-TNF therapy using inhibitors of said cytokine. So far, research has shown, that anti-TNF therapy lowers oxidative stress in patients with Crohn's...

Every day in Russia, about three hundred people get lost, and the percentage of the rescued is not so high. At the moment, special teams of the Ministry of emergency situations and volunteer formations are searching for people. Unmanned aerial vehicles are often involved in the rescue process, as this is a fairly promising area of technology development at the...

I made a model that is capable of one drop and in a few seconds to determine the quality of gasoline. The device measures and displays the obtained data of two main parameters - the octane number from 80 to 100 and the specific active electrical conductivity of gasoline. To increase the accuracy of the readings, a scheme has been...

Gene therapy is a promising approach to the treatment of hereditary and acquired diseases, which consists in the introduction of therapeutic nucleic acids into the cell for a targeted change in its functions. Cationic liposomes are able to protect such nucleic acids from biological factors, and to deliver them into target cells. An important component of cationic liposomes are helper...

Our paper presents the study of cellular structures with the purpose of creating microactuators, some of which have applications in medicine. The microactuators were developed after studying various cellular structures ranging from the F1Fo ATP synthase to the sporangium of the Polypodium aureum fern. The geometrical parameters of the sporangium have been used along with additional data to develop diverse...

Despite extensive research, we still don't know everything about microplastic in the environment. That's why, when I accidentally detected microplastic in bird pellet of protected species, I decided to begin researching this topic. The main purpose of this study was to recognize the contamination of small rivers in urbanized areas of my home city and check how the microplastics are...

Senescence is a state in which cells stop dividing but are metabolically active and release tumour-promoting factors. Chemotherapy can induce transient senescence of cancer cells, which may influence cancer relapse. Hence, eliminating senescent cancer cells with senolytics has potential in anticancer therapy. A process called autophagy may affect the action of senolytics. In my project, I observed that fisetin reduces...

Pell’s equation is a well-known Diophantine equation, which has been studied since ancient times -first by the Greek (the famous cattle problem of Archimedes) and Indian mathematicians (Bhaskara, Brahmagupta), and then in Europe (Brouncker, Euler, Fermat, Lagrange). Pell’s equation is related to many important problems in mathematics, and has applications mainly in algebraic number theory and theory of continued fractions....
