Primary consumer stable nitrogen isotopes as indicators of nutrient source.
Non-point source loading of nitrogen and phosphorus is a primary cause of eutrophication of inland waters, although the diffuse and variable nature of nutrient inputs makes it difficult to trace and identify nutrient pathways. Stable nitrogen isotope values (delta15N) in aquatic biota are thought to reflect anthropogenic nutrient inputs, and they may be a promising tool fortracing nutrient sour...
متن کاملEndogenous surfactant turnover in preterm infants measured with stable isotopes.
We studied surfactant synthesis and turnover in vivo in preterm infants using the stable isotope [U-13C]glucose, as a precursor for the synthesis of palmitic acid in surfactant phosphatidylcholine (PC). Six preterm infants (birth weight, 916 +/- 244 g; gestational age, 27.7 +/- 1.7 wk) received a 24-h [U-13C]glucose infusion on the first day of life. The 13C-enrichment of palmitic acid in surfa...

Naturally occurring ehrlichiosis in Egyptian dogs
Canine ehrlichiosis has emerged as one of the most clinically important tick-borne diseases affecting dogs. Eighty-five naturally infected dogs have been investigated, the most consistent clinical signs recorded were fever, emaciation and lymphoadenopathy, anemia, monocytosis, thrompocytopenia, hypoalbuminemia, elevation in liver enzymes and total bilirubin were the most remarkable changes asso...
متن کاملAnti-C as a naturally-occurring antibody.
IT IS accepted generally that antibodies directed against red blood cell antigens in the Rh system result from isoimmunization either by transfusion or pregnancy and rarely can be considered “naturally-occurring.” Diamond et al. reported the first example of a naturally-occurring antibody within this system in 1942.3 They described an antibody, apparently anti-D, in the serum of a five-year-old...
