Anoxia tolerant brains.
While medical science has struggled to find ways to counteract anoxic brain damage with limited success, evolution has repeatedly solved this problem. The best-studied examples of anoxia-tolerant vertebrates are the crucian carp and some North American Freshwater turtles. These can survive anoxia for days to months, depending of temperature. Both animals successfully fight any major fall in bra...
متن کاملRegulation of intracellular pH in anoxia-tolerant and anoxia-intolerant teleost hepatocytes.
Mechanisms of intracellular pH (pHi) regulation were investigated in anoxia-tolerant hepatocytes from goldfish Carassius auratus, and compared to the situation in the anoxia-intolerant hepatocytes from trout Oncorhynchus mykiss. Under normoxic conditions, the pHi of goldfish hepatocytes was regulated by a Na(+)/H(+) exchanger and a Na(+)-independent Cl(-)/HCO(3)(-) exchanger, the latter being a...
متن کاملBiotechnological approaches to creation of hypoxia and anoxia tolerant plants
The present work provides results of a number of biotechnological studies aimed at creating cell lines and entire plants resistant to anaerobic stress. Developed biotechnological approaches were based on earlier fundamental researches into anaerobic stress in plants, so "Introduction" briefly covers the importance of the problem and focuses on works considering two main strategies of plants ada...
متن کاملAspartate Activation of Pyruvate Kinase in Anoxia Tolerant Molluscs
Abstraet-l . The effects of the amino acid, aspartate, as an allosteric modifier of pyruvate kinase (PK) were surveyed in tissue extracts from 18 species of animals. 2. Aspartate was a strong activator of PK in selected tissues of gastropod and bivalves molluscs, particularly amongst anoxia-tolerant species; with one exception, a polychaete worm, aspartate had no effect on PK from non-molluscan...
متن کاملAnoxia tolerance in rice seedlings: exogenous glucose improves growth of an anoxia-'intolerant', but not of a 'tolerant' genotype.
This study demonstrated that, in rice seedlings, genotypic difference in tolerance to anoxia only occurred when anoxia was imposed at imbibition, but not at 3 d after imbibition. When seeds were imbibed and grown in anoxia, IR22 (anoxia-'intolerant') grew much slower and had lower soluble sugar concentrations in coleoptiles and seeds than Amaroo (anoxia-'tolerant'), while Calrose was intermedia...
