Ecological features of cyanobacteria and algae communities of the littoral of the meromictic Lake Shira (Khakassia Republic, Russia)

During the study of cyanobacteria and algae from littoral of the meromictic Lake Shira (Republic of Khakas- sia, Russia) forty-eight taxa were identified: Cyanobacteria – 7, Chlorophyta – 5, and Bacillariophyta – 36 species. Cyanobacteria were represented by cosmopolitan taxa Leptolyngbya voronichiniana, cf. Trichocoleus hospitus and widely distributed in the freshwater ecosystems species Phormidium cf. paulsenianum, Pseudophormidium cf. golenkinianum, P. pauciramosum, Leptolyngbya perforans, and L. subtilissima. Among green algae typical freshwater taxa Chloroidium saccharophilum, Desmodesmus abundans, Oocystis lacustris, Chlorella sp., Stigeoclonium sp. were detected. Among Bacillariophyta the most frequent species were Amphora ovalis, Cymbella affinis, Encyonema silesiacum, Eunotia fallax, Gomphonella olivacea, G. parvulum, Kobayasiella subtilissima, Navicula minima, N. radiosa, N. veneta, Nitzchia fonti- cola, N. palea, Grunowia tabellaria, Surirella undulata. Several rare species cf. Fragilaria tenera, Grunowia tabellaria and cf. Ulnaria capitata were found. In relation to mineralization indifferents was the largest group (73%). In relation to pH, a unique feature of the investigated lake was the predominance of alkaliphilic species of diatoms (56%), such as Amphora ovalis, Cymbella affinis, Gomphonema truncatum, Hantzschia amphioxys, Navicula minima, N. veneta, Nitzschia cf. linearis, N. palea, Planothidium lanceolatum and other. In the geographic structure cosmopolitan group included 25 species (69%), boreal group – 4 species (11%), arcto-apline group – 2 species (6%). To obtain more accurate informa- tion on the biodiversity of cyanobacteria and algae of Lake Shira further studies using molecular-genetic and electron microscopic methods are needed

Neuropsychological characteristics in children with traumatic brain injury

The psychological characteristics of children, examined in the acute perioif of traumatic brain injuries, are presented. The results of assessment and self-evaluation in our patients are discussed as potential predisposition for being injured.В данной статье рассматриваются психологические особенности детей, осмотренных в остром периоде после получения закрытой черепно-мозговой травмы. Обсуждаются результаты проведенного опроса самооценки с применением «Я-концепции» с точки зрения возможной предрасположенности к получению травм

Влияние социальных факторов, клинических характеристик и коморбидных нарушений на качество жизни пациентов с головной болью напряжения

Here we present the results of our study of the influence of clinical and social parameters as well as co-morbidities (as anxiety, depression, sleep disturbances) on the health related quality of life of 95patients with the most often met primary cephalgias — tension type headache. We used MOS-SF36 (Medical Outcomes Study Short Form-36) as the main instrument to measure health related quality of life. Significant influence of anxiety and depression on the quality of life in patients with both frequent episodic and chronic tension type headache was reported. Anxiety in these patients was mostly associated with psychic health, general health and vitality. In patients with chronic tension type headaches depression was associated with physical functioning; in those with frequent episodic tension type headaches — with social functioning and role functioning due to emotional sate.В статье приводятся результаты исследования влияния клинических параметров, социальных факторов и коморбидных нарушений (тревога, депрессия, нарушения сна) на качество жизни 95 больных с наиболее часто встречающейся формой первичных цефалгий - головной болью напряжения. Для исследования качества жизни в работе использовался Medical Outcomes Study Short Form-36 (MOS SF-36). Определено значительное влияние на качество жизни пациентов с хронической и эпизодической частой головной болью напряжения коморбидных нарушений (тревоги и депрессии). Тревога у этих пациентов в большей степени связана с психическим здоровьем, жизненной активностью и общим состоянием здоровья. У пациентов с хроническими головными болями напряжения депрессия связана с физическим функционированием, при частых эпизодических головных болях напряжения - с социальным функционированием и ролевым функционированием, обусловленным эмоциональным состоянием
