Integrative Zoology, EarlyView.Symbiotic gill and nonsymbiotic mantle of mussel Gigantidas haimaensis responded differently to deep‐sea sampling stress caused by acute environmental changes. Sharply increased transcription factors potentially play key roles in initiating the response of sampled deep‐sea macrobenthos to the sampling stress.

Longevity Humans Have Youthful Erythrocyte Function and Metabolic Signatures
Aging Cell, EarlyView.Longevity humans have “a youthful erythrocyte function and metabolism” with a youth‐like oxygen release and anti‐oxidative capability to combat tissue hypoxia and improve healthspan. ABSTRACT Longevity individuals have lower susceptibility to chronic hypoxia, inflammation, oxidative stress, and aging‐related diseases.

Nitrate reductase for nitrate analysis in water [PDF]
Environmental Chemistry Letters, 2006 Nitrate analysis in water is one of the most frequently applied methods in environmental chemistry. Current methods for nitrate are generally based on toxic substances. Here, we show that a viable alternative method is to use the enzyme nitrate reductase.

Summary Cells of Chlorella vulgaris (Cambridge culture collection, strain 211/12) grown in chemostat under conditions of nitrate limitation, exhibit very high levels of nitrate reductase activity. Similar levels of activity were found in cells grown in chemostat with a limited nitrogen source constituted by 75% ammonium plus 25% nitrate. By contrast,

Nitrate reductase regulation: Effects of nitrate and light on nitrate reductase mRNA accumulation
Molecular and General Genetics MGG, 1989Regulation of nitrate reductase mRNA by light and nitrate was studied in barley seedlings using a partial cDNA clone as a probe. Nitrate reductase mRNA was detected in roots and leaves within 40 min after supplying nitrate to the roots and reached peak accumulation at 2 h in the roots and at 12 h in the leaves.

The existence of a nitrate-reductase operon in the tryptophane region was deduced from the effects of prophage insertion in each of chlI and chlC genes and from transposition of the Mu-mediated host DNA fragments of F-prime. This operon appears to be polarized from chlC to chlI and the gene order in the region is trp -- chlI -- chlC -- purB.
