    Harmful Algal Bloom Bulletins (2018)
    AtlantOS
    In:  AtlantOS Deliverable, D8.6 . AtlantOS, 36 pp.

    Publication Date: 2018-06-13
    Description: Use Case Title: Harmful Algal Blooms Environmental matrix of interest (Air, Ice, Mar. Water, etc.): Marine Study Regions: Shelf Seas in Norway, Ireland and Spain Dissemination Method: Web Providing near real-time and forecast information for the aquaculture industry along Europe’s Atlantic coast is of vital importance in mitigating the effects of HABs. In this task, In-situ and satellite data will be amalgamated in a decision support system. In-situ data include oceanographic data e.g. water column structure, current speeds, biological samples (e.g. algal toxins, phytoplankton cell counts, barcoding) and hydrographic and biogeochemical information where possible. The In-situ data will be used to inform and validate biophysical models and to produce circulation forecasts for the coming three to five days. These data will undergo expert interpretation to produce an early warning bulletin to the aquaculture industry in Spain, Norway and Ireland. The bulletin will be distributed over a specified production season to fish farmers and shellfish production facilities so that husbandry and harvesting techniques can reflect the prevailing HAB conditions at any point in time.

    A fluorescence depolarization study of the orientational distribution of crossbridges in muscle fibres (1994)

    Notes: Abstract A fluorescence depolarization study of the orientational distribution of crossbridges in dye-labelled muscle fibres is presented. The characterization of this distribution is important since the rotation of crossbridges is a key element in the theory of muscle contraction. In this study we exploited the advantages of angle-resolved experiments to characterize the principal features of the orientational distribution of the crossbridges in the muscle fibre. The directions of the transition dipole moments in the frame of the dye and the orientation and motion of the dye relative to the crossbridge determined previously were explicitly incorporated into the analysis of the experimental data. This afforded the unequivocal determination of all the second and fourth rank order parameters. Moreover, this additional information provided discrimination between different models for the orientational behaviour of the crossbridges. Our results indicate that no change of orientation takes place upon a transition from rigor to relaxation. The experiments, however, do no rule out a conformational change of the myosin S 1 during the transition.

    Confocal fluorescence lifetime imaging of free calcium in single cells (1994)
    Springer
    Journal of fluorescence 4 (1994), S. 291-294 
    Details
    ISSN: 1573-4994
    Keywords: Confocal microscopy ; fluorescence lifetime imaging ; calcium green ; Ca2+ imaging
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Ca2+ concentrations in biological cells are widely studied with fluorescent probes. The probes have a high selectivity for free calcium and exhibit marked changes in their photophysical properties upon binding. The differences in the fluorescent lifetime of the probes can now be used as a contrast mechanism for imaging purposes. This technique can be further exploited for the quantitative determination of ion concentrations within the cells. We describe the use of a fast fluorescence lifetime imaging method in combination with a standard confocal laser scanning microscope for the determination of Ca2+ concentrations in single rat cardiac myocytes using the intensity probe Calcium Green.

    Transdermal Macromolecular Delivery: Real-Time Visualisation of Iontophoretic and Chemically Enhanced Transport Using Two-Photon Excitation Microscopy (2000)

    Notes: Abstract Purpose. To investigate the transdermal delivery of a modelmacromolecule by passive and iontophoretic means following pretreatment withC12-penetration enhancers and to visualise transport across humanstratum corneum (SC) in real time. Methods. Transport studies of dextran, labelled with fluorescentCascade Blue® (D-CB; MR = 3 kDa) across human stratum corneum,were conducted during passive and iontophoretic modes of deliveryfollowing pretreatment with either dodecyltrimethylammoniumbromide (DTAB), sodium dodecyl sulphate (SDS) or Azone®.Size-exclusion chromatography was used to assess maintenance of dextranstructural integrity throughout experimental lifetime. Two-photonexcitation microscopy was employed to visualise real-time dextran transportduring current application. Results. The positively charged C12-enhancer DTAB elevated passiveD-CB steady-state flux (Jss) and was the only enhancer to do soabove control during iontophoresis. The negatively charged SDS had theleast effect during both stages. On-line macromolecular transport wasvisualised, indicating both inter- and intra-cellular pathways across SCduring current application. No transport was visible across untreatedSC during passive transport. Conclusions. Use of a positively charged enhancer may improve Jssof anionic macromolecular penetrants during passive and iontophoreticdelivery. On-line visualisation of iontophoresis across SC was possibleand can provide mechanistic insight into SC transport pathways.

    Precision estimates and suggested sample sizes for length-frequency data (2021)
    In:  http://aquaticcommons.org/id/eprint/8936 | 403 | 2012-06-27 16:56:01 | 8936 | United States National Marine Fisheries Service

    Description: For most fisheries applications, the shape of a length-frequency distribution is much more important than its mean length or variance. This makes it difficult to evaluate at which point a sample size is adequate. By estimating the coefficient of variation of the counts in each lengthclass and taking a weighted mean of these, a measure of precision was obtained that takes the precision in all length classes into account. The precision estimates were closely associated with the ratio of the sample size to the number of size classes in each sample. As a rule-of-thumb, aminimum sample size of 10 times the number of length classes in the sample is suggested because the precisiondeteriorates rapidly for smaller sample sizes. In absence of such a rule-of-thumb, samplers have previouslyunder-estimated the required sample size for samples with large fish, while over-sampling small fish of the same species.
