Consequently several researches have been centered to find the isosmotic point, where the organism doesn't use the energy for osmoregulation and therefore it channels it to growth.
After Isovolumic exchange of blood with an isosmotic albumin solution, the animals showed the typical symptoms of oxygen deficiency shock.
Aquatic and land exercise training affects renal runction in rats under isosmotic volume expansion.
Therefore, increases in osmolality, in values below the isosmotic point of seminal plasma, could be the main responsible factor for sperm activation.
Furthermore, when crabs are acclimated to an intermediate salinity below the isosmotic point to elevate CAc mRNA, and are then moved to a lower salinity, subsequent increases in CA activity still take on the order of days (Mitchell and Henry, 2014).
According to Pequeux (1995), there are two broad categories of euryhaline invertebrates in respect to osmotic regulation: the "strong regulators", which can maintain their hemolymph osmolality almost constant in a wide range of external salinity values, and the "weak regulators", which only osmoregulate within a narrow range of external salinity values and whose hemolymph osmolality drops, more or less in parallel with the isosmotic line, when the medium salinity falls below a certain limit (PRUSCH, 1983).
1997), Protection against water loss is mainly based on the oliguria: urine will concentrate until it is isosmotic in retation to plasma.
As a result of these reabsorptive and secretory processes, the osmolarity of the tubular fluid at the end of the PT is isosmotic, that is, essentially equivalent to plasma, or approximately 300 mOsm/L.
Glycine has the advantages of being isosmotic (thus it does not cause hemolysis) and nonconducting (thus allowing for electrocoagulation without charge dispersal).
However, this tradeoff was not observed in Pagurus minutus in water of our experimental salinity regimes, because significantly different osmoregulation abilities were not found in isosmotic and hypersaline regimes (i.
