Studies on Nitrogen Metabolism of Soybean Plants : I. Transport and metabolism of labelled and non-labelled nitrogen

Effect of rhizobium and nitrogen on soybean

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Novel metabolism of nitrogen in plants.

Our previous study showed that approximately one-third of the nitrogen of 15N-labeled NO2 taken up into plants was converted to a previously unknown organic nitrogen (hereafter designated UN) that was not recoverable by the Kjeldahl method (Morikawa et al., 2004). In this communication, we discuss metabolic and physiological relevance of the UN based on our newest experimental results. All of t...

Metabolism of 14C-labelled alphaxalone in man.

The metabolism of 14C-labelled alphaxalone, dispensed as Althesin, was studied in normal patients, patients with obstructive jaundice and patients with chronic renal disease and anuria. The radioactive label was removed rapidly from the plasma following i.v. administration. The major portion of the label was excreted in the urine. In patients with normal renal function 14C-labelled alphaxalone ...

Interaction of cytosolic and plastidic nitrogen metabolism in plants.

In angiosperms, the assimilation of ammonia resulting from nitrate reduction and from photorespiration depends on the operation of the plastidic GS/GOGAT cycle. The precursor for ammonia assimilation, 2-oxoglutarate, is synthesized in the mitochondria and in the cytosol. It is imported into the plastid by a 2-oxoglutarate/malate translocator (DiT1). In turn, the product of ammonia assimilation,...
