β-Glutamine-mediated self-association of transmembrane β-peptides within lipid bilayers
No full textTransmembrane beta-peptide helices and their association in lipid membranes are still widely unexplored. We designed and synthesized transmembrane beta-peptides harboring different numbers of D-beta(3)-glutamine residues ((h)Gln) by solid phase peptide synthesis. By means of circular dichroism spectroscopic measurements, the secondary structure of the beta-peptides reconstituted into unilamellar vesicles was determined to be similar to a right-handed 3(14)-helix. Fluorescence spectroscopy using D-beta(3)-tryptophan residues strongly suggested a transmembrane orientation. Two or three (h)Gln served as recognition units between the helices to allow helix-helix assembly driven by hydrogen bond formation. The association state of the transmembrane b-peptides as a function of the number of (h)Gln residues was investigated by fluorescence resonance energy transfer (FRET). Therefore, two fluorescence probes (NBD, TAMRA) were covalently attached to the side chains of the transmembrane beta-peptide helices. The results clearly demonstrate that only beta-peptides with (h)Gln as recognition units assemble into oligomers, presumably trimers. Temperature dependent FRET experiments further show that the strength of the helix-helix association is a function of the number of hGln residues in the helix
A combined Phase Contrast Imaging and heterodyne interferometer for multiscale fluctuation measurements in tokamak plasmas
No full textAn upgrade to the Phase Contrast Imaging (PCI) diagnostic on the DIII-D tokamak has successfully combined PCI with density interferometry to provide electron density fluctuation measurements across an unprecedented range in wavenumber. The combined diagnostic uses a single laser and a single beam path through the tokamak, minimizing machine resources in anticipation of future reactor-scale devices where port access will be at a premium. The PCI multichannel detector provides low-noise, wavenumber-resolved detection of moderate-wavenumber turbulence, while the interferometer channel is sensitive to long-wavelength turbulence, including the peak of ion-scale turbulence and MHD. The overlap in wavenumber range between the two schemes allows for an in situ absolute calibration of the PCI

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

Research of acute influence of new fertlizer «Rost-concentrate» on the hydrobionts Сyprinus carpio L. and Daphnia magna Straus
No full textPurpose. To establish and assess acute toxicity parameters of "ROST-concentrate (10+7+7)" acute toxicity for planktonic crustacean Daphnia magna Straus and carp fingerlings Cyprinus carpio L.
Methodology."ROST-concentrate (10+7+7)" contains macronutrients (nitrogen, phosphorus, potassium), which are valuable for the pond ecosystem, and trace elements in environmentally safe chelate form.
We determined the vital (LC0), absolutely lethal (LC100) and median (LC50) drug concentrations on the test organisms such as crustacean D. magna (Cladocera) and carp fingerlings C. carpio. The determination of acute lethal toxicity on D. magna was conducted according to DSTU 4173: 2003 that corresponded to the international standard ISO 6341: 2012, MOD [7]. The temperature of the experiment was 20±0.5 oC. The exposure time - 96 hours. Daphnia were not fed. Following "ROST-concentrate (10+7+7)" concentrations were tested: 100; 75; 50; 25; 10; 1; 0.5; 0.1; 0.05; 0.01; 0,005; 0,001 ml/dm3.
We also determined the acute lethal toxicity on carp fingerings with an average weight of 6.78±0.63 grams following the standardized procedure [8]. Pond water was used in the experiment. Ten fish were placed into a 40 L aquarium. Following concentrations of "ROST-concentrate (10+7+7)" were investigated: 0,5; 1; 2; 3; 4; 5; 6; 7; 8; 9; 10; 15; 20; 30; 40 mg/L. The exposure time was 24 hours. Water temperature was 19±1oC. LC50 drug median concentration was calculated according to G. Kerber method.
Findings. The parameters of integral acute toxicity of "ROST-concentrate (10+7+7)" on typical organisms of fish pond ecosystems.With 96 h exposure on juvenile cladoceran D. magna, lethal concentration was LC100 = 5,00 ml/dm3, median concentration was LC50 = 0,15 ml/dm3, vital concentration was LC0 = 0,01 ml/dm3. According to the classification of toxic substances, the "ROST-concentrate (10+7+7)" is characterized by low toxicity on juvenile cladoceran D. magna. With 24 h exposure on carp fingerling: lethal concentration was LC100 = 40,0 ml/dm3, median concentration was LC50 = 18,6 ml/dm3, vital concentration was LC0 = 7,0 ml/dm3. According to the classification of toxic substances [11], "ROST-concentrate (10+7+7)" was practically nontoxic to 6.78 ± 0.63 g carp juveniles.
Originality. First study of the acute effect of organic-mineral preparation "ROST-concentrate (10+7+7)" on planktonic cladoceran D. magna and carp juvenile C. carpio.
Practical value. The obtained results show a very low level of toxicity of the drug and safety for organisms of fish-breeding pond ecosystem organisms after its application
