The waters of the Curonian Lagoon and the contiguous coastal area are linked together by both the environment and economic activities. Regional planning considers water and coastal areas as separate phenomena that lack a common management system. However, this approach is poorly applicable to the Curonian Lagoon, the delta of the River Neman, and the adjacent coastal area. Only when these elements are analysed as a single whole, one can see the problems of the region in their entirety. This article...

In patients with acute coronary syndrome, hyperglycemia is observed, which is represented by elevated fasting plasma glycemia and glycated hemoglobin levels. It was found that an increase in the level of glycated hemoglobin was accompanied by an increase in the level of triglycerides, total serum cholesterol. At the same time, glycated hemoglobin correlated especially with the parameters of fat metabolism — total serum cholesterol, high-density lipoproteins, low-density lipoproteins and triglycerides...

The border as a spatial and socio-cultural phenomenon has been an immediate subject of study for a long time. A convincing reason supporting this statement is the existence of an independent branch of science on borders, "limology" (Latin: limes — Border). For the geographical sciences border is also a traditional subject of study, where the interest focuses on its impact on the geographical objects (border regions) and the functions possessed by the border rather than the border itself...

The Kaliningrad region is a small territory of Russia in the centre of Europe. It differs from other Russian regions in natural conditions and reclamation history. The recent socioeconomic development has been associated with anthropogenic pressure on natural and cultural landscapes created during seven hundred years. It has a negative effect on the environment. The author considers several nature management practices and suggests using the landscape approach for the optimization of nature management...
