Nutritional support is a primary therapy administered to oiled animals during responses to oil spills, but data informing nutritional decision-making during events are limited. In this study, 44 common murres ( Uria aalge ) and 6 Western grebes ( Aechmophorus occidentalis ), naturally oiled by oceanic seeps off the coast of Ventura and Santa Barbara Counties, CA, USA, were assigned to 1 of 4 groups fed diets with varying levels (6.8% [no added oil], 11%, and 20%) and types (salmon, corn) of oil added to a partially purified basal diet...

Effective anti-osteopenia therapy can be achieved by designing long-term protein/peptide drug delivery systems for bone trabecula restoration. Here we show that a complex of salmon calcitonin and oxidized calcium alginate (sCT-OCA) was prepared and loaded into a thermosensitive copolymer hydrogel for long-term anti-osteopenia treatment. The triblock copolymer, poly(D,L-lactic acid-co-glycolic acid)-b-poly(ethylene glycol)-b-poly(D,L-lactic acid-co-glycolic acid) (PLGA-PEG-PLGA) exhibited sol-gel transition at body temperature...

Peter Salmon, Bridget Young
OBJECTIVE: Clinical communication literature currently distinguishes clinicians' emotional care of patients from instrumental aspects of clinical care, and regards clinicians' explicit emotional engagement with patients as the key to emotional care. Here we critically appraise this view. METHODS: We draw on empirical evidence and recent reviews and critiques focusing on cancer care. RESULTS: Patients and families do not generally seek explicit emotional engagement from their practitioners; nor does such engagement consistently improve patient outcomes...

Jie Yang, Yoosun Chu, Mary Anne Salmon
Background and Objectives: Older lesbian, gay, bisexual, and transgender (LGBT) adults are more likely to live alone and less likely to have children compared with their heterosexual counterparts. The lack of immediate family system can render older LGBT adults particularly vulnerable to social isolation and its consequences. The current study utilizes social exclusion theory, which asserts that not only material resources but also engagement with and inclusion into the society are necessary for marginalized people to be integrated into the mainstream...

We report on the effect of hydrostatic pressure on the electrical conductivity and dielectric permittivity of the [Fe(Htrz)2(trz)](BF4) (Htrz = 1H-1,2,4, triazole) spin crossover complex. Variable temperature and pressure broadband imped-ance spectrometry revealed a piezo-resistive effect of more than one order of magnitude for pressures as low as 500 bar, associated with a large pressure-induced hysteresis of 1700 bar. The origin of the piezo-resistive effect has been attributed to the pressure induced spin-state switching in the complex and the associated P,T phase diagram was determined...

Understanding the impacts of recreational fishing on habitats and species, as well as the social and ecological importance of place to anglers, requires information on the spatial distribution of fishing activities. This study documented long-term changes in core fishing areas of a major recreational fishery in Alaska and identified biological, regulatory, social, and economic drivers of spatial fishing patterns by charter operators. Using participatory mapping and in-person interviews, we characterized the spatial footprint of 46 charter operators in the communities of Sitka and Homer since the 1990s...

The myxozoan endoparasite Tetracapsuloides bryosalmonae causes temperature-driven proliferative kidney disease (PKD) in salmonid fishes. Despite the economic and ecological importance of PKD, information about the distribution of the parasite is still scarce. Here, we report for the first time the occurrence of T. bryosalmonae in wild brown trout Salmo trutta and European grayling Thymallus thymallus populations in Finland. We detected T. bryosalmonae at high prevalence in both brown trout and European grayling from the transboundary Finnish-Russian River Koutajoki system (Rivers Oulankajoki, Kuusinkijoki, Kitkajoki, Maaninkajoki, and Juumajoki) in north-eastern Finland...

Comparative models suggest that effects of dietary tryptophan (Trp) on brain serotonin (5-hydroxytryptamine; 5-HT) neurochemistry and stress responsiveness are present throughout the vertebrate lineage. Moreover, hypothalamic 5-HT seems to play a central role in control of the neuroendocrine stress axis in all vertebrates. Still, recent fish studies suggest long-term effects of dietary Trp on stress responsiveness, which are independent of hypothalamic 5-HT. Here, we investigated if dietary Trp treatment may result in long-lasting effects on stress responsiveness, including changes in plasma cortisol levels and 5-HT neurochemistry in the telencephalon and hypothalamus of Atlantic salmon...

Immunoglobulin M plays a key role in systemic protection of Atlantic salmon against pathogens. Until recent, studies have focused on antigen-specific antibodies and little is known about the IgM repertoire: its size, developmental changes and responses to antigens. We report the development of deep sequencing protocol to characterize the repertoire of IgM heavy chain variable region. Its structure and changes were examined at the early stages of life and after infection with virus of cardiac myopathy. Clonotypes are identified by the V and J gene segments and amino acid sequences of CDR3, which determine the contribution of the heavy chain to the antigen binding properties...

In pediatric brain tumours, dissemination of malignant cells within the central nervous system confers poor prognosis and determines treatment intensity, but is often undetectable by imaging or cytology. This study describes the use of fluorescence lifetime (FLT) imaging microscopy (FLIM), a novel diagnostic tool, for detection of metastatic spread. The study group included 15 children with medulloblastoma and 2 with atypical teratoid/rhabdoid tumour. Cells extracted from the tumour and the cerebrospinal fluid (CSF) 2 weeks postoperatively and repeatedly during chemo/radiotherapy were subjected to nuclear staining followed by FLT measurement and cytological study...

Ichthyoarchaeological evidence is uncommon at ancient hunter-gatherer sites from various regions and timeframes. This research contributes to the development of microarchaeological techniques useful for identifying fishing economies in situations where classifiable bones are unavailable. Specifically, traces of heat altered bone mineral in domestic hearths are expected to provide markers for discarded fish remains. We used a series of laboratory incineration experiments to characterize the mineralogy of burned salmonid vertebrae...

Docosahexaenoic acid (DHA) is present in high concentrations in salmon, herring, and trout. Epidemiologic studies have shown that high dietary consumption of these and other oily fish is associated with reduced rates of myocardial infarction, atherosclerosis, and other ischemic pathologies. Atherosclerosis is induced by inflammation and can lead to acute cardiovascular events and extensive plaque. DHA inhibits the development of inflammation in endothelial cells, alters the function and regulation of vascular biomarkers, and reduces cardiovascular risk...

PURPOSE: The foveal avascular zone (FAZ) is altered in numerous diseases. We assessed factors (axial length, segmentation method, age, sex) impacting FAZ measurements from optical coherence tomography (OCT) angiography images. METHODS: We recruited 116 Caucasian subjects without ocular disease, and acquired two 3 × 3 mm AngioVue scans per each right eye (232 total scans). In images of the superficial plexus, the FAZ was segmented using the AngioVue semiautomatic nonflow measurement tool and ImageJ manual segmentation...

Potential interactions between marine predators and humans arise in the southern coast of Chile where predator feeding and reproduction sites overlap with fisheries and aquaculture. Here, we assess the potential effects of intensive salmon aquaculture on food habits, growth, and reproduction of a common predator, the spiny dogfish-identified as Squalus acanthias via genetic barcoding. A total of 102 (89 females and 13 males) individuals were collected during winter and summer of 2013-2014 from the Chiloé Sea where salmon aquaculture activities are concentrated...

Alternative reproductive tactics (ARTs) are prevalent in nature, where smaller parasitic males typically have better sperm quality than larger territorial guard males. At present, it is unclear what is causing this phenomenon. Our objective was to gain insights into sperm form and function by examining flagellar beating patterns (beat frequency, wave amplitude, bend length, bend angle, wave velocity) and biomechanical sperm metrics (velocity, hydrodynamic power output, propulsive efficiency) of wild spawning Chinook salmon ARTs...

This study presents the first isolation of Tenacibaculum maritimum from farmed Atlantic salmon Salmo salar in Chile. The isolate, designated T. maritimum Ch-2402, was isolated from gills of Atlantic salmon in a farm located in region X, Los Lagos Chile, during the harmful algal bloom caused by Pseudochattonella spp. in February 2016. The algal bloom is reported to have caused 40,000 tons of mortality in this salmon farming area. The bacterium, T. maritimum is recognized as an important pathogen of marine fish worldwide causing tenacibaculosis...

CXC chemokine receptor 2 (CXCR2) is a key receptor in the chemotaxis of neutrophils to sites of inflammation. The studies reported here describe the pharmacological characterization of danirixin, a CXCR2 antagonist in the diaryl urea chemical class. Danirixin has high affinity for CXCR2, with a negative log of the 50% inhibitory concentration (pIC50) of 7.9 for binding to Chinese hamster ovary cell (CHO)-expressed human CXCR2, and 78-fold selectivity over binding to CHO-expressed CXCR1. Danirixin is a competitive antagonist against CXCL8 in Ca2+ mobilization assays, with a Kb of 6...

One factor potentially limiting the uptake of Rasmussen's (1997) Accimap method by practitioners is the lack of a contributing factor classification scheme to guide accident analyses. This article evaluates the intra- and inter-rater reliability and criterion-referenced validity of a classification scheme developed to support the use of Accimap by led outdoor activity (LOA) practitioners. The classification scheme has two levels: the system level describes the actors, artefacts and activity context in terms of 14 codes; the descriptor level breaks the system level codes down into 107 specific contributing factors...
