Pharmacokinetics of oxytetracyline in Arctic charr
Ž . Ž The pharmacokinetics of oxytetracycline OTC was studied in Arctic charr SalÕelinus alpinus . Ž . L. in freshwater at a mean water temperature of 6.38C, after intravascular i.v.; 10 and 20 mgrkg Ž . and oral p.o.; 50 and 100 mgrkg administration. Two different oral formulations were tested as carriers for OTC; one in which OTC was dissolved in agar, the other where OTC was encapsulated in ...
متن کاملDevelopment and Underdevelopment in Britain and Ireland
Many people, covering many academic disciplines, have an interest in what they would refer to as development, and approach it from the direction of what they conceive to be underdevelopment. This type of labelling customarily follows on from some narrower interest; either in a particular region (for example Africa, Asia, Latin America); or in a particular place (e.g. Nigeria, Brazil, China); or...
متن کاملBehaviour, physiology and carotenoid pigmentation in Arctic charr Salvelinus alpinus.
The behaviour during an exploration task and the response to a confinement stress of Arctic charr Salvelinus alpinus were evaluated. Behaviour of individuals during 90 min of exploration was classified into high and low activity. High-activity individuals had higher plasma cortisol levels following stress compared to low-activity individuals. This indicates that high- and low-activity individua...
متن کاملToxicokinetics and effects of PCBs in Arctic fish: a review of studies on Arctic charr.
In a series of environmentally realistic laboratory experiments, toxicokinetics and effects of polychlorinated biphenyls (PCBs) were studied in the Arctic charr (Salvelinus alpinus). Winter fasting and emaciation, which are common among Arctic charr living in high latitudes, resulted in a redistribution of the lipophilic PCBs from lipid-storing tissue such as the muscle, to vital organs that mu...
متن کاملPatterns of MiRNA Expression in Arctic Charr Development
Micro-RNAs (miRNAs) are now recognized as a major class of developmental regulators. Sequences of many miRNAs are highly conserved, yet they often exhibit temporal and spatial heterogeneity in expression among species and have been proposed as an important reservoir for adaptive evolution and divergence. With this in mind we studied miRNA expression during embryonic development of offspring fro...
