Knowledge about the cumulative impacts of anthropogenic activities and environmental conditions on marine ecosystems is incomplete and details are lacking. Compositional community changes can occur along gradients, and community data can be used to assess the state of community resilience against combined impacts of variables representing human pressures and environmental conditions. Here we use a machine learning approach, i.

The global industrialization of seascapes and climate change leads to an increased risk of severe impacts on marine ecosystem functioning. While broad scale spatio-temporal assessments of human pressures on marine ecosystems become more available, future trajectories of human activities at regional and local scales remain often speculative. Here we introduce a stepwise process to integrate bottom-up and expert-driven approaches for scenario development to inform cumulative effects assessments and related marine spatial planning (MSP).

Sustainability in the provision of ecosystem services requires understanding of the vulnerability of social-ecological systems (SES) to tipping points (TPs). Assessing SES vulnerability to abrupt ecosystem state changes remains challenging, however, because frameworks do not operationally link ecological, socio-economic and cultural elements of the SES. We conducted a targeted literature review on empirical assessments of SES and TPs in the marine realm and their use in ecosystem-based management.

The diel vertical distribution of young-of-the-year (YOY) burbot Lota lota in the pelagic zone of Lake Constance was compared to light intensity at the surface and to the light intensity at their mean depth. Lota lota larvae inhabited the pelagic zone of Lake Constance from the beginning of May until the end of August. From early June, after the stratification of the water column, fish performed diel vertical migrations (DVM) between the hypolimnion and epilimnion.

Background: A previous study from Germany showed high antibiotic use in university hospitals, particularly in intensive care units (ICU) and hematology-oncology services, but there has been no information about recent antibiotic use in non-university hospitals. In the present study, we collected data from 40 non-university regional general hospitals located in the southwestern part of the country, and analyzed use density in the medical and surgical services of these hospitals.

Materials And Methods: Hospital pharmacy records for the calendar years 2001 and 2002 were evaluated.

Molar dentine was sliced into 100 nm ultrathin sections, by means of a focused ion beam, for observation by energy-filtering transmission electron microscopy (EFTEM). Within the matrix, crystals approximately 10 nm wide and 50-100 nm long were clearly observed. When carbon and calcium were mapped in electron spectroscopic images by EFTEM, carbon failed to localize in crystals.

The element signal obtained from electron-energy-filtered micrographs depends on the systematic error in calculating the background and on the noise in the background-corrected image. Both systematic error and statistical fluctuation of the background can be assessed experimentally with a specimen that combines the element-containing feature with a mass-thickness marker. The approach is described for the mapping of phosphorus in turnip yellow mosaic viruses prepared on a supporting carbon film of variable thickness.

Background: Geriatric patients with long-term urinary catheters have an increased morbidity and mortality. It is conceivable that catheter replacement causes bacteremia and contributes to this morbidity and mortality. The purpose of our study was to determine the incidence and clinical relevance of bacteremia induced by urinary catheter replacements.

Myosin-associated giant protein kinases of the titin/witchin-like superfamily have previously been implicated in the regulation of muscle function, based on genetic and physiological studies. We find that recombinant constitutively active Caenorhabditis elegans and Aplysia twitchin kinase fragments differ in their catalytic activities and peptide-substrate specificities, as well as in their sensitivities to the naphthalene sulfonamide inhibitors 1-(5-chloronaphthalenesulfonyl)-1H-hexahydro-1,4-diazepine (ML-7) and 1-(5-iodonaphthalenesulfonyl)-1H-hexahydro-1,4-diazepine (ML-9). The constitutively active Aplysia twitchin kinase fragment has a remarkably high activity (Vmax > 100 mumol.

The calcium-dependent interaction of two synthetic peptides derived from the putative calmodulin-binding site in the protein kinase autoinhibitory region of twitchin was studied by fluorescence and CD spectroscopy. The peptides interacted with dansylcalmodulin in the presence of Ca2+ as shown by a change in the fluorescence emission spectra. Fluorescence titration of dansylcalmodulin with the peptides was used to quantify this interaction.

The unusually large (approximately 600 to > 3000 kDa) myosin-associated proteins of the titin/twitchin superfamily are considered to be important cytoskeletal rulers for thick filament assembly in muscle. This function is maintained by approximately 60-240 modular fibronectin-type-III and immunoglobulin-C2 repeats in these proteins which further contain a protein serine/threonine kinase domain of unknown function. In this study, the bacterially expressed kinase domain of Aplysia twitchin was used in order to identify a potential physiological substrate.

Myomodulin A (MMA) application or stimulation of neuron B16, which releases MMA, increases cAMP levels in the accessory radula closer (ARC) muscle of Aplysia. MMA application also increases cAMP-dependent protein kinase (cAPK) activity in one subcellular compartment of the muscle. These results suggest that at least part of MMA's effects in this system are mediated via the cAPK signal transduction pathway.

Application of small cardioactive peptide (SCP) or stimulation of motorneuron B15 increases the level of activated cAMP-dependent protein kinase (cAPK) in the ARC muscle. SCP application also appears to induce a translocation of cAPK between different subcellular compartments of the ARC muscle and this translocation is also induced by cAMP addition to muscle homogenates. These results suggest that the actions of SCP in the Aplysia ARC neuromuscular system are mediated via the cAPK signal transduction pathway.

Acting through a cAMP-cAMP-dependent protein kinase (cAPK) cascade, members of two neuropeptide families, the small cardioactive peptides and myomodulins, modulate contraction amplitude and relaxation rate in the accessory radula closer (ARC) muscle of the marine mollusc Aplysia californica. An approximately 750-kDa phosphoprotein was identified in the ARC muscle as the major substrate for cAPK activated either by application of neuropeptides or by peptides released by motorneuron stimulation at physiological frequencies. Immunoblot and immunoelectron microscopy experiments revealed the widespread presence of this protein in Aplysia muscles and its colocalization with contractile filaments in the ARC muscle.

An approximately 750-kDa member of the family of giant titin/twitchin-like myosin-associated proteins was highly purified from muscle of the marine mollusc Aplysia californica. Purified twitchin was able to autophosphorylate on threonine, which demonstrates its protein serine/threonine kinase activity. cDNA sequence analysis of the cloned kinase domain of molluscan twitchin revealed that it is most closely related with the kinase domains of Caenorhabditis elegans twitchin (62% identity) and vertebrate myosin light chain kinases (45% average identity).
