Malignant melanoma is the most severe form of all skin cancers with a particular poor prognosis once metastases have developed. Angiogenesis, the formation of new blood vessels, is a prominent feature of human melanoma, which have angiogenic activity already early in development. This is at least partly ascribed to the action of MAPK- and PI3K pathways which are hyperactivated in most melanoma. Animal models which combine in depth in vivo examinations with the opportunity to perform small molecu...

no / Chronic wounds often result from prolonged inflammation involving excessive polymorphonuclear leukocyte activity. Studies show that the omega-3 polyunsaturated fatty acids eicosapentaenoic and docosahexaenoic acids found in fish oils generate bioactive lipid mediators that reduce inflammation and polymorphonuclear leukocyte recruitment in numerous inflammatory disease models. The purpose of this study was to test the hypotheses that boosting plasma levels of eicosapentaenoic and docosahex...

Background: Neonates born with low birth weight or preterm are at an increased risk of long-term adverse health outcomes. Research studies on the association of fish consumption during pregnancy and birth outcomes, have led to inconsistent conclusions. Maternal dietary intakes during pregnancy have a significant impact on foetal development and growth. The aim of this project is to determine levels of maternal fish intake at <18 weeks during pregnancy and to determine the association with birth ...

Coral reefs are priority habitats which are vulnerable to natural and anthropogenic disturbances. These can cause phase shifts from coral habitat to degraded algal-dominated states – and consequent changes in the distribution, abundance and activity of associated fish species. In the eastern Red Sea, human-induced reef degradation is likely to increase with planned development of the Saudi Arabian coast and the changing climate. The present study therefore investigates the ecological effects of ...

<p>Sedimentation and drawdown-induced habitat degradation limits reproduction of structure-associated fishes in flood control reservoirs. Littoral habitat enhancement can be accomplished by planting fast growing crops during winter, when lakebeds are exposed, to provide fish habitat during spring flooding. It remains unclear if species of crops differ in their submerged persistence or habitat quality to fish. I submerged six species of cool-season annual crops in mesocosms and monitored plant ar...

Angelerfolg hängt vom Fischverhalten ab und selektiver Fang aufgrund vererbbarer Verhaltensmerkmale kann sich auf Fischpopulationen auswirken. Die anglerische Vulnerabilität ergibt sich aus einer Kombination aus dem Zustand des Fisches, dem Zusammentreffen mit dem Fanggerät und den Eigenschaften desselben. Höhere Aktivität sollte die Begegnungswahrscheinlichkeit mit dem Fanggerät und dadurch die Vulnerabilität steigern. Ziel dieser Arbeit war es zu verstehen, wie Bewegungsmuster die Vulnerabilit...

Content: Fish collagen has been considered to be an alternative for mammalian collagen, however, physicochemical properties of fish collagen-based materials such as gels are so far not adequate for actual application. In the present study, we prepared two types of fish collagen gels with sufficient elasticity: i) dehydrated fibrillogenesis collagen gels (DFCG), which were fabricated via collagen self-assembly followed by immersion in different concentrations of ethanol solutions, and ii) dehydra...

Polar zooplankton and fish safeguard against the seasonality of food availability by using the summer months to build large reserves of lipids, which in turn are utilized to meet the metabolic demands of apex predators such as penguins, seals, and whales. A warming trend in the northern part of the western Antarctic Peninsula (WAP) has led to a decrease in perennial and summer sea ice, an increase in heat content over the shelf, and lower phytoplankton biomass, which could affect prey quality. W...

Only a miniscule fraction of the world’s largest volume of living space, the ocean’s mid-water biome, has ever been sampled. As part of the International Census of Marine Life field project Mid-Atlantic Ridge Ecosystems (MAR-ECO), a discrete-depth trawling survey was conducted in 2009 aboard the NOAA ship Henry B. Bigelow to examine the pelagic faunal assemblage structure and distribution over the Charlie-Gibbs Fracture Zone (CGFZ) of the northern Mid-Atlantic Ridge. This is the first MAR-ECO pr...

The use of community-based participatory research (CBPR) methods to conduct environmental exposure assessments provides valuable insight about disparities in fish consumption and contaminant exposure. Ninety-five community-specific fish consumption surveys were administered to low-income African American women (ages 16--49) residing in the Southeast community of Newport News, Virginia, USA, in 2008. The mean fish consumption rate for the women surveyed was 147.8 g/day (95% CI: 117.6-185.8), a ra...

Thousands of floating objects, known as drifting fish aggregating devices (dFADs), are released every year by commercial tropical tuna purse seine vessels in the three equatorial oceans to aggregate tuna and increase catch. The escalation in the number of dFADs deployed over the last three decades has caused changes in fishing effort that are poorly reflected in traditional indices of purse seine effort and catch per unit of effort (CPUE). In addition, concerns have been raised regarding the imp...

The marine fish family Ephippidae comprises eight genera and 15 species of extant fishes. Spadefishes or batfishes inhabit nearshore tropical to temperate waters. They are almost circumglobal in distribution, with the highest diversity in the Indo-west Pacific and the lowest diversity in the east Pacific and west Atlantic. Fifty-nine potentially informative morphological characters, 10 outgroup taxa, and eight ingroup taxa (i.e., genera) were used to explore sister group hypotheses to the Ephipp...

Taking an ecosystem approach to fisheries requires the consideration of relevant ecological processes within research and assessment frameworks. Processes affecting ecosystem productivity can be categorized as biophysical (climate variability, primary production), exploitative (fishing), or trophodynamic (food web interactions). This dissertation incorporates these three governing processes to characterize spatiotemporal diversity and population abundance trends for multiple demersal fish and in...

Mercury concentrations and determinants of mercury accumulation were examined for ten finfish species from the lower Chesapeake Bay and its tributaries. None of the sampled fish had total mercury concentrations approaching the U.S. EPA human health screening value. Mercury concentrations in different fish species generally increased with increasing delta 15N, but not delta 13C, suggesting that trophic position, but not dietary carbon source was a dominant determinant. A methylmercury biomagnific...

The phylogeny of the Piscicolidae was analyzed from combined sequence data of 18S rDNA, cytochrome c oxidase subunit I (CO-I), nicotinamide adenine dinucleotide dehydrogenase subunit I (ND-I), and morphological data using parsimony. A worldwide distribution of Pisciolidae was represented for the first time in a phylogenetic analysis. While the family Piscicolidae was supported as a monophyletic group, the traditional subfamilies based on morphology were not supported. The Platybdellinae was poly...

Cataract formation in the Elizabeth River (ER) has been reported since 1986. Previous studies have concentrated on describing cataract as a function of exposure to polluted sediments, especially polycyclic aromatic hydrocarbons (PAH). These studies, however, have not examined what processes might be involved in fish cataractogenesis. The overall objective of this research was to identify important processes associated with the early development of cataract in feral fish populations. Field studie...

Toxaphene bioaccumulation and translocation capacity was quantitatively evaluated in the Wolf River, Mississippi. Water, sediment, and fish samples were collected monthly and/or quarterly and evaluated for their role in accumulation and importance in translocating toxaphene. Water samples exhibited very low occurrence of toxaphene as determined by Gas-Chromatographic (G-C) analysis. The ability of water to expose both organisms and sediments to toxaphene, plus the role water plays in translocati...

There are a variety of chromosomal abnormalities such as translocation, duplication, deletion, insertion and inversion, which may cause severe diseases, e.g., cancers and birth defects. Multi-color fluorescence in-situ hybridization (M-FISH) is an imaging technique popularly used for simultaneously detecting and visualizing these complex abnormalities in a single hybridization. In spite of the advancement of fluorescence microscopy for chromosomal abnormality detection, the quality of the fluor...

It is a widely accepted assumption that fish predation controls structure and functioning of aquatic food webs. In the past, however, a large part of effort was concentrated on lakes and reservoirs. Thus, the knowledge about stream ecosystems is much more rudimentary than that for lakes in this respect. The aim of this thesis, therefore, was to describe and assess the effects of fish predation in natural stream ecosystems. For that purpose a reach scale field experiment was set up using an exper...

This project was performed on assigment of Vattenfall R&amp;D in Älvkarleby. The project was a first step in evaluating whether bubble curtains with vertical tubes could be suitable for diverting fish from hydro power intakes into fish passages. To determine this, prototypes were constructed, where one was tested in still water and one in running water. The tests in still water were carried out in a large cylindrical tank and the tests in running water were carried out in Kungsr¨annan in ¨Alvkarleb...

According to the Food Allergen Labeling and Consumer Protection Act, fish is one of the eight major allergen foods. Reliable analytical methods for the detection of food ingredients derived from fish are important for the protection of fish allergic individuals. Surimi is defined as a protein concentrate made of fish muscle and is usually used for the manufacture of shellfish analogues or substitutes. They are typically made from white-flesh fish (e.g. pollock or whiting) and may be a hidden ing...
