The influence of different lighting sources on growth and development of tomato plants

Comparative study was conducted on morphofunctional parameters of tomato plants (Solanum lycopersicum L.) under diverse supplementary lighting conditions - electrodeless lamps (EL), high-pressure mercury arc lamps (HPM) and high-pressure sodium arc lamps (HPS). The work showed, that plants, cultivated under 5,000 lux EL lighting, had higher morphometric parameters, their leaves contained more chlorophyll, and they were outgrown, in comparison to plants, growth in HPS and HPM lighting conditions. These results demonstrate the profitableness of EL light flux, which contains constant PAR spectrum, for tomato plants growth and development

Social wellbeing of older people and their emotional burnout out

The subject of the research is evaluating social and emotional wellbeing of the elderly people. We set a goal to study social and emotional wellbeing of the aged and formulate the principles of its evaluating. The urgency of the work is that the organization of the aged's activity affords to improve the level of their emotional wellbeing

Reproductive biology of a rare species Begonia ludwigii in greenhouse conditions of the Siberian Botanical Garden of Tomsk State University

The paper presents the results of a reproductive biology study and the Begonia ludwigii seasonal development rhythm - a species classified by the International Union for Conservation of Nature as a rarity category EN (endangered species). The studies have shown that when cultivated in the Tomsk State University Siberian Botanical Garden greenhouse conditions, this species has high potential seed productivity (about 75,000 ovules per inflorescence), high fertility and pollen viability, but at the same time low true seed productivity (seed rate not more than 27%). It was established that the Begonia ludwigii seeds, in the greenhouse conditions, are tied to heterogamous pollination due to the absence of pollinating insects. The use of xenogamous artificial pollination increased the coefficient of seed productivity by almost 3 times. The paper also describes the full seasonal development rhythm, flowering biology, biomorphological features of pollen and seeds

Genetic Spectrum of Idiopathic Restrictive Cardiomyopathy Uncovered by Next-Generation Sequencing.

BACKGROUND:Cardiomyopathies represent a rare group of disorders often of genetic origin. While approximately 50% of genetic causes are known for other types of cardiomyopathies, the genetic spectrum of restrictive cardiomyopathy (RCM) is largely unknown. The aim of the present study was to identify the genetic background of idiopathic RCM and to compile the obtained genetic variants to the novel signalling pathways using in silico protein network analysis. PATIENTS AND METHODS:We used Illumina MiSeq setup to screen for 108 cardiomyopathy and arrhythmia-associated genes in 24 patients with idiopathic RCM. Pathogenicity of genetic variants was classified according to American College of Medical Genetics and Genomics classification. RESULTS:Pathogenic and likely-pathogenic variants were detected in 13 of 24 patients resulting in an overall genotype-positive rate of 54%. Half of the genotype-positive patients carried a combination of pathogenic, likely-pathogenic variants and variants of unknown significance. The most frequent combination included mutations in sarcomeric and cytoskeletal genes (38%). A bioinformatics approach underlined the mechanotransducing protein networks important for RCM pathogenesis. CONCLUSIONS:Multiple gene mutations were detected in half of the RCM cases, with a combination of sarcomeric and cytoskeletal gene mutations being the most common. Mutations of genes encoding sarcomeric, cytoskeletal, and Z-line-associated proteins appear to have a predominant role in the development of RCM
