A group of medical and environmental researchers from RUDN University evaluated the level of heavy metals in the organism of first-year university students from different countries of the world. The results of the screening helped the scientists to reveal a relationship between a region of residence and the level of toxic metal in organism. According to their opinion, increased heavy metal levels in the organism of students from Africa and Latin America can have a negative impact on their health and performance.
A biologist from RUDN University found the most beneficial concentration of tryptophan for rainbow trout. When added to the diet of the fish, this amino acid supports the immune system and reduces the oxidative stress in the intestinal tract caused by the overpopulation of fish farms.
A team of chemists from RUDN University suggested a new reaction to produce organic compounds in one vessel. The end products turned out to be effective against the cells of carcinomas, including drug-resistant ones.
A team of soil scientists from RUDN University organized a summer school to study urban soils in 5 climatic zones. Students from Germany, Russia, China, and the USA spent two weeks analyzing the state of soils and vegetation in cities and towns all the way from the Barents to the Azov Sea. The results of their study confirmed the effect of urbanization on the soil such as decrease of soil acidity, increase of carbon concentrations, and shrinkage of tree trunks by 40% — 60%.
A mathematician from RUDN University developed a matrix representation of set functions. This approach is vivid and easy to check, and it makes the calculations easier. Among other things, the new development can be applied to cooperative game theory.
RUDN University doctors found alterations in serum amino acid profile in children with attention deficit hyperactivity disorder (ADHD). The findings will help to understand the mechanism of the disorder and develop new treatment strategies.
RUDN University doctors found out what role macrophages play in the recovery of the liver after the removal of its significant part.
According to a team of ecologists from RUDN University, polycyclic aromatic hydrocarbons (PAHs) can be used as pollution indicators and help monitor the movement of pollutants in environmental components such as soils, plants, and water. To find this out, the team conducted a large-scale study of a variety of soil, water, and plant samples collected from a vast area from China to the Antarctic.
A team of researchers found out that children with autistic spectrum disorder (ASD) have increased levels of the amino acid hydroxyproline. According to the medics, this may be associated with joint hypermobility, a common symptom in ASD patients. This information can help improve anti-ASD therapy.
A team of biologists from RUDN University working together with foreign colleagues summarized the results of 520 studies on the impact of manure on the soil and created a snapshot of all biochemical processes that go on in fertilized soils. The team also compared the effect of manure with and without mineral additives, showed how manure from different animals affects the fertility of the soil, and calculated the optimal amount of manure for soil fertilization.
RUDN University biotechnologists have created a method for detection of bacterial infection in apple, pear, hawthorn and other plants of the Rosaceae family. The test does not require laboratory equipment, the result is ready in 10 minutes. This will allow detecting the disease quickly and prevent the spread of infection.
Alkylation reactions are used in the petrochemical industry to obtain high-octane number components for gasolines. A chemist from RUDN University found a way to speed this process up to 24 times. To do so, he developed a catalyst based on silica and niobium.
