Benefits of haemoglobin in the cladoceran crustacean Daphnia magna.
To determine the contribution of haemoglobin (Hb) to the hypoxia-tolerance of Daphnia magna, we exposed Hb-poor and Hb-rich individuals (2.4-2.8 mm long) to a stepwise decrease in ambient oxygen partial pressure (P(O(2)amb)) over a period of 51 min from normoxia (20.56 kPa) to anoxia (<0.27 kPa) and looked for differences in their physiological performance. The haem-based concentrations of Hb i...
متن کاملThe Daphnia Genomics Consortium Meeting: the genome biology of the model crustacean Daphnia.
The fourth Daphnia Genomics Consortium Meeting was held from July 7th through July 9th, 2007 at Indiana University (Bloomington, IN, USA). This year’s meeting was entitled The Genome Biology of the Model Crustacean Daphnia and was highlighted by the initial public release of the draft version of the Daphnia pulex genome. In collaboration with the US Department of Energy Joint Genome Institute (...
متن کاملOptimisation of DNA extraction from the crustacean Daphnia
Daphnia are key model organisms for mechanistic studies of phenotypic plasticity, adaptation and microevolution, which have led to an increasing demand for genomics resources. A key step in any genomics analysis, such as high-throughput sequencing, is the availability of sufficient and high quality DNA. Although commercial kits exist to extract genomic DNA from several species, preparation of h...
متن کاملThe dichotomous oxyregulatory behaviour of the planktonic crustacean Daphnia magna.
The dual function of appendage movement (food acquisition, ventilation) proved to be the key to explaining the peculiar oxyregulatory repertoire of the planktonic filter feeder Daphnia magna. Short-term hypoxic exposure experiments with normoxia-acclimated animals under varying food concentrations revealed a dichotomous response pattern with a compensatory tachycardia under food-free conditions...
متن کاملSuppression of Eicosanoid Biosynthesis During Coronary Angioplasty
Background. Percutaneous transluminal coronary angioplasty (PTCA) is an acute, localized stimulus to platelet and vascular function. Periprocedural cardiovascular complications are reduced by moderate-dose aspirin (ASA), presumably due to inhibition of thromboxane (TX) A2. Methods and Results. Excretion ofTXA2 and prostacyclin (PGI2) metabolites in urine increased during PTCA. Pretreatment for ...
