[Breathing disorders during sleep in patients with dystrophic myotonia].

Objective: To analyze the results of nocturnal breathing parameters during sleep based on nocturnal pulse oximetry and to study of characteristics of external respiration in genetically confirmed patients with dystrophic myotonia (DM).

Material And Methods: The subjects of the study were patients with genetically confirmed DM types 1 and 2 who were hospitalized in the neurological departments of the Republican Scientific and Practical Center for Neurology and Neurosurgery. The clinical picture of the disease, comorbidities, sleep questionnaires, laboratory tests, overnight pulse oximetry and spirometry were performed and analyzed.

Combining citizen and conventional science for microplastics monitoring in the White Sea basin (Russian Arctic).

The study presents the results of the field expedition in the Russian Arctic held by a group of NGO members, scientists and volunteers in summer-autumn 2020 in the Arkhangelsk Region (Russia). The survey showed microplastics presence in 7 out of 13 remote and sparsely inhabited locations in lakes, rivers and coastal areas of the White Sea basin, with microplastic particle average concentration 1.14 part/m, that is in agreement with other recent regional studies.
