... and revealed constant uptake rates for particulate organic carbon (POC) (−0.315±0.161 mg POC m −2 coral surface area h −1 ), particulate nitrogen (PN) (−0.053±0.018 mg PN m −2 h −1 ) and dissolved organic carbon (DOC) (−4.8±2.1 mg DOC m −2 h −1 ). Although DOC uptake significantly increased in the N treatment...

... N-enriched DFAAs, and % 15 N enrichment was measured both in animal tissue and zooxanthellae at different DFAA concentrations,incubation time and light levels. As previously observed for urea, which is another source of organic nitrogen, DFAA uptake exhibited a biphasic mode consisting of an active...

... and PMSF comparable to those to which Hsp-exposed eggs were exposed had no effect on the time to nuclear envelope breakdown or cleavage. To evaluate the uptake of extracellular Hsc/Hsp70 in unfertilized eggs,various preparations of labeled protein were used. For some experiments, Hsc70 or Hsc/Hsp70...

.... The effects of amino acids upon intestinal zinc uptake in freshwater rainbow trout ( Oncorhynchus mykiss ) were studied using an in vivo perfusion technique. The presence of histidine, cysteine and taurine had distinct modifying actions upon quantitative and qualitative zinc absorption, compared to perfusion...

... of a shared transport site for Zn and Ca at the apical membrane of the gill epithelium and suggest that there is a certain degree of coregulation of branchial Zn and Ca uptake in rainbow trout. Removal of Ca from the water resulted in a large (six-to 24-fold) increase in affinity (decreased K m ) for Zn...

...I. D. Hume; W. H. Karasov; B. W. Darken ABSTRACT We have measured unidirectional uptake (not transmural flux) of acetate, butyrate and proline by everted sleeves of intact tissue from the jejunum, caecum, proximal colon and distal colon of prairie voles ( Microtus ochrogaster ). There was active...

... sample from uncannulated trout exposed to radiolabelled Zn in the water. Trout acclimated to tapwater (Ca 2+ = 2·0 mequiv P 1 ) and exposed to Zn (1·5–45·9 /μequiv I −1 ; 0·05–1·5 mg I −1 ) showed saturable uptake which was apparently first order with no significant linear component. The apparent J max...
