In aquatic organisms, such as fish, blood is continually exposed to aquatic contaminants. Multidrug Resistance (MDR) proteins are ubiquitous detoxification membrane pumps, which recognize various xenobiotics. Moreover, their expression is induced by a large class of drugs and pollutants. We have highlighted ...
La presente invenzione si riferisce ad un sistema di posizionamento subacqueo e ad un metodo per determinare la posizione di un terminale subacqueo.
Background The dmrt1 and sox9 genes have a well conserved function related to testis formation in vertebrates, and the group of fish presents a great diversity of species and reproductive mechanisms. The lambari fish (Astyanax altiparanae) is an important Neotropical species, where studies on molecular ...
It is widely expected that physiological and behavioral stress responses will be integrated within divergent stress-coping styles (SCS) and that these may represent opposite ends of a continuously varying reactive–proactive axis. If such a model is valid, then stress response traits should be repeatable ...
Cryptic species complexes are common among parasites, which tend to have large populations and are subject to rapid evolution. Such complexes may arise through host-parasite co-evolution and/or host switching. For parasites that reproduce directly on their host, there might be increased opportunities ...
Photocrosslinked hydrogels reinforced by microfibrillated cellulose (MFC) were prepared from a methacrylate-functionalized fish elastin polypeptide and MFC dispersed in dimethylsulfoxide (DMSO). First, a water-soluble elastin peptide with a molecular weight of ca. 500 g/mol from the fish bulbus arteriosus ...
Extramedullary T-lymphoblastic blast crisis of chronic myelogenous leukemia (CML) is uncommon and the prognosis is poor. It was usually misdiagnosed as the co-existence of T-lymphoblastic lymphoma (T-LBL) and CML. In the present study, we report a patient with CML, who developed extramedullary T-lymphoblastic ...
Matching the trend seen among the major large rivers of the globe, the Amazon River and its tributaries are facing aquatic ecosystem disruption that is affecting freshwater habitats and their associated biodiversity, including trends for decline in fishery resources. The Amazon’s aquatic ecosystems, ...
Age-related variation in demographic rates is now widely documented in wild vertebrate systems, and has significant consequences for population and evolutionary dynamics. However, the mechanisms underpinning such variation, particularly in later life, are less well understood. Foraging efficiency is ...
Swimming exercise at optimal speed may optimize growth performance of yellowtail kingfish in a recirculating aquaculture system. Therefore, optimal swimming speeds (Uopt in m s−1 or body lengths s−1, BL s−1) were assessed and then applied to determine the effects of long-term forced and sustained swimming ...
Genetic improvement for enhanced disease resistance in fish is an increasingly utilized approach to mitigate endemic infectious disease in aquaculture. In domesticated salmonid populations, large phenotypic variation in disease resistance has been identified but the genetic basis for altered responsiveness ...
Yersinia ruckeri SC09 is a Gram-negative bacterium isolated from a moribund Ictalurus punctatus collected in Jianyang, China. Here, we report the complete genome sequence of this microorganism to facilitate the investigation of its pathogenicity and to reevaluate its taxonomic position.
Consumer growth and reproductive capacity are direct functions of diet. Strongylocentrotid sea urchins, the dominant herbivores in California kelp forests, strongly prefer giant kelp (Macrocystis pyrifera), but are highly catholic in their ability to consume other species. The biomass of Macrocystis ...
This invention relates to a device for tying crabs and a method of using the same device in which it helps the user to tie the crabs more quickly and efficiently, thus satisfying the safety requirement for food processing and reducing the chance of disputes. [Image Omitted]
The present invention relates to the method of producing an antimicrobial composition characterized in that it comprises the steps of: a) splitting a lauric oil treated with activated carbon; and b) recovering a composition comprising 90% or more, by weight of free fatty acids. The invention further ...
Device for singularizing fish comprising a roll pair (8) rotating from each other and where fish to be singularized is supplied at one end (9) of the pair. The roll pair is slightly inclined and/or is provided with at least one water nozzle at the end (9) of the roll pair (8) where fish is supplied. ...
The invention relates to a method for impregnating a liquid material into a rope comprising a plurality of fibers and interstices between said fibers, said method comprising the steps of: (a) Providing a liquid material in a tank, said liquid material defining a level of liquid in said tank; (b) Providing ...
A method for conveying logging tools (LT) and obtaining well log data from a wellbore is disclosed. The method includes running a drill string (DS) including a landing sub (LS) disposed near the lower end into a wellbore. A logging tool string (LTS) is inserted into the upper end of the DS bore. A fluid ...
Background During larval settlement and metamorphosis, marine invertebrates undergo changes in habitat, morphology, behavior and physiology. This change between life-cycle stages is often associated with a change in diet or a transition between a non-feeding and a feeding form. How larvae regulate ...
