Defining an ageing-related pathology, disease or syndrome: International Consensus StatementNARA Subscribed
Around the world, individuals are living longer, but an increased average lifespan does not always equate to an increased health span. With advancing age, the increased prevalence of ageing-related diseases can have a significant impact on health status, functional capacity and quality of life. It is therefore vital to develop comprehensive classification and staging systems for ageing-related pathologies, diseases and syndrom...
Summary cueO encodes a periplasmic multicopper oxidase, which is known to be involved in copper homeostasis and protection against oxidative stress in Escherichia coli K12. Transcriptional profiling showed that expression of genes associated with motility was lowered in a cueO mutant while expression of genes associated with autoaggregation was elevated. Increased aggregation was correlated with increased expression of cell su...
Accessory pigments versus chlorophyll a concentrations within the euphotic zone: A ubiquitous relationshipNARA Subscribed
Remotely sensed chlorophyll a (Chl a ) concentrations are determined by the ratio of upwelled radiances within the Soret band of Chl a (443 nm) and at 550 nm. Absorption at wavelengths outside this band (>460 nm) is dominated by accessory pigments and for the successful measurement of Chl a (e.g., 490:550 nm and 520:550 nm ratios) early Coastal Zone Color Scanner investigators speculated that these accessory pigments must cova...
