Homeostasis, failure of homeostasis and degenerate ion channel regulation

REGULATION OF ACID-BASE HOMEOSTASIS BY THE KIDNEY

Regulation of ion homeostasis under salt stress.

When under salt stress, plants maintain a high concentration of K(+) and a low concentration of Na(+) in the cytosol. They do this by regulating the expression and activity of K(+) and Na(+) transporters and of H(+) pumps that generate the driving force for transport. Although salt-stress sensors remain elusive, some of the intermediary signaling components have been identified. Evidence sugges...

Photosynthesis Properties and Ion homeostasis of Different Pistachio Cultivar Seedlings in Response to Salinity Stress

Understanding mechanisms of salt tolerance, physiological responses to salt stress, and screening genotypes for breeding programs are important scientific issues remained to be investigated in pistachio. Therefore, current study was carried out to investigate response of different pistachio cultivars (G1, G2, Kaleghochi and UCB1) to salinity treatments (0.6 as control, 10, 20 dS m-1 using salin...

Neuroendocrine regulation and homeostasis.

This special issue of the Journal of Neuroendocrinology comprises five review articles, centred on the theme of the neuroendocrine regulation of homeostasis, and provides a snapshot of the sessions at the 2013 International Workshop in Neuroendocrinology (IWNE). The workshop was held in Santa Clara Resort, in the town of Dourado, S~ao Paulo, Brazil, from 4–7 August 2013 and emerged from the uni...

Metal ion transporters and homeostasis.

Transition metals are essential for many metabolic processes and their homeostasis is crucial for life. Aberrations in the cellular metal ion concentrations may lead to cell death and severe diseases. Metal ion transporters play a major role in maintaining the correct concentrations of the various metal ions in the different cellular compartments. Recent studies of yeast mutants revealed key el...
