High-quality Bi2Se3 microcrystals were grown by the physical vapor transport （PvT） method without using a foreign transport agent. The microplate crystals grown under the optimal temperature gradient are well faceted and have dimensions up to -200 μm, The growth proceeds by the layer-by-layer mecha- nism with the formation of flat low-growth rate facets. The phase composition of the grown crystals was identified by the X-ray single crystal structure analysis in space group R3m, a = 4.1356（3）, C= 28.634（5）A, Z=3 （R=0.0147）. The most probable twin planes in the tetradymite structure were evaluated by the pseudo translational sublattice merhad.

Response of wild Avena species to fungal infection of grain

The Crop Journal 2017年第6期5卷 499-508页

作者： T.Yu.Gagkaeva O.P.gavrilova A.S.Orina E.v.Blinova I.G.Loskutov All-Russian Institute of Plant Protection (vIZR) St-Petersburg Pushkin 196608 Russia N.I.vavilov All-Russian Institute of Plant Genetic Resources (vIR) St-Petersburg 190000 Russia St-Petersburg State University St-Petersburg 199034 Russia

Sixty-six accessions belonging to Avena species(A. atlantica, A. canariensis, A. clauda, ***, A. hirtula, A. longiglumis, A. wiestii, A. agadiriana, A. barbata, A. vaviloviana, ***, A. magna, A. murphyi, ***, A. ludoviciana, A. occidentalis, A. sterilis, A. sativa, and A. byzantina) obtained from the N. I. vavilov Institute of Plant Genetic Resources(vIR) were tested for the infection of grain by Alternaria and Cladosporium at the genus level and by a group of trichothecene-producing Fusarium fungi. Real-time PCR was performed to quantify fungal abundance and ELISA was performed for mycotoxin analysis in grain. The average amounts of all tested fungi in tetraploid Avena species were higher than those in diploid and hexaploid species. Low amounts of deoxynivalenol(DON) were detected in seven hexaploid genotypes(A. sterilis, A. byzantina, A. sativa, and A. fatua) and one diploid genotype(***). The relationship between some morphological traits(1000-grain weight, percent of husk, trichome density, and plant height) of Avena species and grain infection by fungi and mycotoxins was investigated. Alternaria and Cladosporium fungi could not penetrate the husk. A highly negative correlation of the amounts of their DNA with the proportions of husk in grain as well as with trichome density was found. In contrast, a significant positive correlation between the amount of Fusarium DNA and these traits was found. A strong negative correlation bctween plant height and DNA of the analyzed fungi was found. The oats least infected by Alternaria, Cladosporium, and Fusarium fungi and containing low amounts of DON were accessions of the hexaploids A. byzantina, ***, A. sativa, A. sterilis,and the diploid A. lwiestii.

Progression of Cognitive Deficit in Older People with Mild Cognitive Impairment Treated with Cerebrolysin

Health 2014年第19期6卷 2581-2591页

Mukaetova-Ladinska Laboratory of Neurochemistry Moscow Russia Department of Alzheimer’s Disease and Related Disorders Moscow Russia Department of Bioengineering and Medical Equipment and Systems Moscow State Technical University Moscow Russia Laboratory of Biostatistics and Evidence Based Medicine Mental Health Research Center of Russian Academy of Medical Sciences Moscow Russia Institute of Neurocience Newcastle University Institute for Ageing Newcastle University Campus for Ageing and Vitality Newcastle upon Tyne UK

Objectives: Although people with amnestic mild cognitive impairment (aMCI) benefit from cerebrolysin treatment, some still develop dementia. The aim of the current study was to identify most informative clinical assessment tests to predict the therapy efficacy in aMCI subjects treated with cerebrolysin. Methods: We studied patients with amnestic mild cognitive impairment (aMCI;n = 53) who had regular neurocognitive and clinical psychiatric assessments and were treated with cerebrolysin i.v. infusions 20 × 30 ml twice a year over three years period. Data were analyzed using non-parametric statistics, cluster and linear discriminant analyses. Results: Combined mathematical modeling enabled to predict cognitive decline from aMCI to dementia in the cerebrolysin-treated patients based on their initial neurocognitive assessment scores. We identified a “dementia risk group” with fast cognitive decline (i.e. low efficacy of the treatment). Lower baseline scores in the Mattis Dementia Rating Scale Memory subtest, Mini-Mental State Examination (MMSE), 10 word list immediate recall, and Frontal Assessment Battery tests when accompanied by higher depression score (Hamilton Depression Rating Scale) suggest poor prognosis for aMCI patients treated with cerebrolysin. Changes in scores on the MMSE, Boston naming test, Digit span forward, and Wechsler scale subtest “Categorical associations” during the treatment course are more characteristic for patients who convert to dementia than their initial scores. Conclusions: aMCI subjects treated with cerebrolysin with lower baseline cognitive functioning and subclinical depression have poor prognosis in terms of converting to dementia. Changes in the MMSE, Boston naming test, Digit span forward, and Wechsler scale subtest “Categorical associations” scores during the treatment course are more informative to identify patients who will develop dementia than their initial scores.

基于心率变异性指标研究视障滑雪运动员对竞技状态的适应特点。采用实验法对42名滑雪项目的高级运动员进行分组,其中:由23名视障滑雪运动员组成实验组;19名无视障的俄罗斯国家队滑雪运动员组成对照组。实验过程:分析安静时和训练大周期准备期运动员身体负荷测试时的心率变异性指标。结果表明,依据心率变异性指标,视障滑雪运动员对竞技状态的适应,与对照组相比,具有更高的生理学指标"值"。在安静时视障滑雪运动员表现出较低的功能节省化,同样降低了对负荷调节系统的动员。视障运动员携带的心率监视器为分析训练负荷与运动员机体功能是否适宜提供了预测信息。
