Correction to "Safety and Efficacy of Gadobutrol for Contrast-enhanced Magnetic Resonance Imaging of the Central Nervous System: Results from a Multicenter, Double-blind, Randomized, Comparator Study"
No full textContrast-enhanced magnetic resonance imaging (MRI) of the central nervous system (CNS) with gadolinium-based contrast agents (GBCAs) is standard of care for CNS imaging and diagnosis because of the visualization of lesions that cause blood-brain barrier breakdown. Gadobutrol is a macrocyclic GBCA with high concentration and high relaxivity. The objective of this study was to compare the safety and efficacy of gadobutrol 1.0 M vs unenhanced imaging and vs the approved macrocyclic agent gadoteridol 0.5 M at a dose of 0.1 mmol/kg bodyweight
Swarming and complex pattern formation in <it>Paenibacillus vortex </it>studied by imaging and tracking cells
No full textAbstract Background Swarming motility allows microorganisms to move rapidly over surfaces. The Gram-positive bacterium Paenibacillus vortex exhibits advanced cooperative motility on agar plates resulting in intricate colonial patterns with geometries that are highly sensitive to the environment. The cellular mechanisms that underpin the complex multicellular organization of such a simple organism are not well understood. Results Swarming by P. vortex was studied by real-time light microscopy, by in situ scanning electron microscopy and by tracking the spread of antibiotic-resistant cells within antibiotic-sensitive colonies. When swarming, P. vortex was found to be peritrichously flagellated. Swarming by the curved cells of P. vortex occurred on an extremely wide range of media and agar concentrations (0.3 to 2.2% w/v). At high agar concentrations (> 1% w/v) rotating colonies formed that could be detached from the main mass of cells by withdrawal of cells into the latter. On lower percentage agars, cells moved in an extended network composed of interconnected "snakes" with short-term collision avoidance and sensitivity to extracts from swarming cells. P. vortex formed single Petri dish-wide "supercolonies" with a colony-wide exchange of motile cells. Swarming cells were coupled by rapidly forming, reversible and non-rigid connections to form a loose raft, apparently connected via flagella. Inhibitors of swarming (p-Nitrophenylglycerol and Congo Red) were identified. Mitomycin C was used to trigger filamentation without inhibiting growth or swarming; this facilitated dissection of the detail of swarming. Mitomycin C treatment resulted in malcoordinated swarming and abortive side branch formation and a strong tendency by a subpopulation of the cells to form minimal rotating aggregates of only a few cells. Conclusion P. vortex creates complex macroscopic colonies within which there is considerable reflux and movement and interaction of cells. Cell shape, flagellation, the aversion of cell masses to fuse and temporary connections between proximate cells to form rafts were all features of the swarming and rotation of cell aggregates. Vigorous vortex formation was social, i.e. required > 1 cell. This is the first detailed examination of the swarming behaviour of this bacterium at the cellular level.</p
Dimensionality of the rosenberg self-esteem scale among greek primary school students
No full textThe aim of the current study was to validate the self-report version of the Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1965) structure in a sample of Greek primary school students. The study was based on the original one-factor model suggested by the scale's author, as well as on the two-factor correlated model of positive and negative items. Participants were 652 primary school students (N=652, M=10.02, SD=1.160). The psychometric properties of the RSES were assessed by conducting a Confirmatory Factor Analysis (CFA). Both average variance extracted and composite reliability were used to test the internal consistency and convergent validity. The correlated two-factor model provided a better fit to the data than the one-factor model, according to the CFA. This conclusion is based on the analysis results, which comprised as providing good fit if non-significant X2 values, X2 /df 0.90), as well as the root mean square error of approximation (RMSEA) < 0.06 (Hu & Bentler, 1999). The main contribution of this study was the adaptation and evaluation of the RSES for use of Greek students and the determination of its factor structure. Teachers and researchers could also use this interpreted scale to determine the level of self-esteem in primary school children and form strategies to increase their self-esteem. © 2021 Eskisehir Osmangazi University.

Curing Cholera: Pathogens, Places and Poverty in South Asia
No full textIn this paper I will seek to provide a new understanding of endemicity of disease in India. Through a study of cholera research in the twentieth century I will argue that disease and its endemicity has to be understood in biological factors as well as within a wider social and economic context. I will discuss the medical efforts at locating the causality of cholera from the nineteenth century in Indian climate, water bodies and human anatomy to show that cholera is no more a biological phenomena than water is an ecological or environmental problem. Both are essentially political and economic questions

Life histories of burrowing mayflies (Hexagenia limbata and H. rigida, Ephemeroptera: Ephemeridae) in a northern Canadian reservoir
No full text1. The life histories and population dynamics of the burrowing mayflies Hexagenia limbata and H. rigida were examined from 1986 to 1988 in four regions of an impounded lake in northern Manitoba, Canada. 2. Bottom temperatures reached 15-20-degrees-C, but ice-free periods of 4-6 months resulted in annual degree day (dd > 10-degrees-C) accumulations of only 210-650 in various regions and years. 3. The life cycles (egg to adult) of both Hexagenia species required 3 yr in the three warmest regions studied and 4 yr in the coolest area; total dd accumulations to complete the life cycle ranged from 1222 to 1468 dd > 10-degrees-C. 4. Fecundity (no. of eggs/female) was strongly correlated to body size of subimagos, and subimago size was strongly correlated to length of nymphal exuviae, so field collection of nymphal exuviae could be used to determine both the size and fecundity of the emerging females. 5. Degree day accumulation in the final year before emergency was a better predictor of emergence timing than overall dd accumulations for the life cycle.PT: J; CR: BRITT NW, 1962, B OHIO BIOL SURVEY, V1, P1 BRITTAIN JE, 1982, ANNU REV ENTOMOL, V27, P19 BURTON W, 1973, J FISH RES BOARD CAN, V30, P287 CARLANDER KD, 1967, ECOLOGY, V48, P873 CLIFFORD HF, 1974, CAN ENTOMOL, V106, P1111 DANKS HV, 1987, BIOL SURVEY CANADA M, V1 EDMUNDS GF, 1976, MAYFLIES N CENTRAL A FLANNAGAN JF, 1979, 2ND P INT C EPH KRAK, P103 FREMLING CR, 1973, 1ST P INT C EPH LEID, P12 GIBERSON DJ, 1991, AMBIO, V20, P139 GIBERSON DJ, 1991, THESIS U MANITOBA WI GIBERSON DJ, 1992, 1837 CAN TECHN REP F GIBERSON DJ, 1992, J N AMER BENTHOL SOC, V11, P181 GIBERSON DJ, 1992, J N AMER BENTHOL SOC, V11, P194 HAMILTON AL, 1974, FISHERIES LIMNOLOG G, V1 HARPER F, 1981, CAN J ZOOL, V59, P1784 HECKY RE, 1984, CAN J FISH AQUAT SCI, V41, P579 HECKY RE, 1984, CAN J FISH AQUAT SCI, V41, P720 HEISE BA, 1987, J N AM BENTHOL SOC, V6, P230 HIGLEY LG, 1986, ENVIRON ENTOMOL, V15, P999 HUDSON PL, 1972, STUDIES NATURAL SCI, V1, P1 HUNT BP, 1951, FLORIDA ENTOMOLOGIST, V34, P59 HUNT BP, 1953, MICHIGAN DEP CONSERV, V4 LYMAN FE, 1944, ENTOMOL NEWS, V55, P207 MCCAFFERTY WP, 1975, T AM ENTOMOL SOC, V101, P447 MCCAFFERTY WP, 1984, ANN ENTOMOL SOC AM, V77, P69 MOZLEY SC, 1988, J GREAT LAKES RES, V14, P171 NEAVE F, 1932, CONTRIBUTIONS CANADI, V7, P177 NEWBURY RW, 1984, CAN J FISH AQUAT SCI, V41, P548 NEWBURY RW, 1984, CANADIAN J FISHERIES, V41, P558 OLIVER DR, 1960, J FISH RES BOARD CAN, V17, P607 PRUESS KP, 1983, ENVIRON ENTOMOL, V12, P613 RAWSON DS, 1953, J FISH RES BOARD CAN, V10, P486 RIKLIK L, 1982, CAN J ZOOL, V60, P2317 RUTTER RP, 1972, THESIS MIAMI U OXFOR SCHLOESSER DW, 1984, J GREAT LAKES RES, V10, P435 SOUTHWOOD TRE, 1978, ECOLOGICAL METHODS STANLEY EH, 1988, OIKOS, V51, P313 SWEENEY BW, 1978, SCIENCE, V200, P444 SWEENEY BW, 1984, ECOLOGY AQUATIC INSE, P56 TAKEMON Y, 1990, MAYFLIES STONEFLIES, P61 TOKESHI M, 1985, J ANIM ECOL, V54, P919 WELCH CL, 1989, HYDROBIOLOGIA, V185, P183 WHELAN KF, 1980, ADV EPHEMEROPTERA BI, P187 WIENS AP, 1984, CAN J FISH AQUAT SCI, V41, P638; NR: 45; TC: 10; J9: FRESHWATER BIOL; PG: 18; GA: PY758Source type: Electronic(1
Platinum carboxylato-pendant-arm macrocycles: structure, redox properties and anti-cancer potential
No full textIn an attempt to generate new platinum compounds that may be effective in the treatment of cancer, as well as having a lower toxicity than traditional platins and being orally viable, we are studing the synthesis and reactivity of platinum complexes of tetraazamacrocycles bearing carboxylato pendant arms. We have synthesized adducts of meso- and rac-5,5,7,12,12, 14-hexamethyl-1,4,8,11-tetraazacyclotetradecane-1,7-diacetic acid ((LH2)-H-1). The meso-(PtL1)-L-II complex is unstable with respect to disproportionation, forming platinum metal and [meso-(PtL1)-L-IV](2+). The rac-isomer shows less tendency to disproportionate. Cyclic voltammetry suggests that the rac-(PtL1)-L-II complex undergoes two one-electron oxidations. Using bis-triazacyclononanenickel(III), [Ni-III(tacn)(2)](3+) as an outer-sphere oxidant, the self-exchange rate for the [Pt-II/L-III](0/+) couple has been estimated at 0.034 M-1 s(-1).

APPLICATION OF THE NARRATIVE APPROACH AND THE CONCEPT OF NONVIOLENT COMMUNICATION BY M. ROSENBERG IN THE RESOCIALIZATION PROCESS
No full textObsahem této práce je zapojení konceptu nenásilné komunikace M.Rosenberga a využití práce s narativem do probační práce s odsouzenými osobami (dohledovými klienty Probační a mediační služby). Autorka je přesvědčena, že oba tyto prvky v sobě mají potenciál k pozitivní změně u odsouzených, mohou vést ke zvýšení jejich prosociálních dovedností, a tedy dobře sloužit jako nástroje resocializace. Pro tento účel vytvořila tematické pracovní listy pro probační úředníky pro přímou práci s klienty (pro vedení dialogu), přičemž základ pracovních listů tvoří narativ v různých podobách. Pro tvorbu pracovních listů využila arteterapeutických technik, logoterapeutického pohledu a konceptu nenásilné komunikace.The content of this work is the involvement of the concept of non-violent communication by M. Rosenberg and the use of narrative work in probation work with convicted persons (supervision clients of the Probation and Mediation Service). The author is convinced that both of these elements have the potential for positive change in convicts, can lead to an increase in their prosocial skills, and thus serve well as tools for resocialization. For this purpose, she created thematic worksheets for probation officers to work directly with clients (to conduct a dialogue), while the basis of the worksheets is narrative in various forms. She used art therapy techniques, a logotherapy perspective and the concept of nonviolent communication to create worksheets.Fakulta filozofickáStudentka obhájila s odbornou znalostí a pečlivostí závěrečnou práci.
