A morphometric method for correcting phytoplankton cell volume estimates
(Springer-Verlag, 1977-06)
Cell volume calculations are often used to estimate biomass of natural phytoplankton assemblages. Such estimates may be questioned due to morphological differences in the organisms present. Morphometric analysis of 8 species ...
Observations on chytridiaceous parasites of phanerogams
(Springer-Verlag, 1977-09)
Host symptoms and morphology of the endo-and epibiotic stages of a Physoderma on Phalaris arundinacea L. are described. It is considered identical with a Physoderma on Agropyron repens earlier described. Both are referred ...
The enzymatic exchange of the acyl group of acyl dihydroxyacetone phosphate with free fatty acids
(Elsevier, 1977-01-10)
Ehrlich ascites cell microsomes catalyze the exchange of the acyl group of acyl dihydroxyacetone phosphate with free fatty acids. The reaction does not require ATP and CoA.
When are two qualitative taxonomic characters compatible?
(Springer-Verlag, 1977-06)
A proof is given of a procedure that has previously appeared claiming to determine when two amino acid positions on a protein could both possibly be divergent taxonomic characters. An algorithm for executing this procedure ...
A path analysis of the causal relationships between red cell glycolytic intermediates, ADP and ATP in sickle cell anemia
(Elsevier, 1977-12)
The statistical relationships among the glycolytic intermediates (GIs) of the Embden-Meyerhof pathway, adenine nucleotides (ANs) and various hematological measures were estimated for 34 sickle cell anemia patients. ...
Structure of the semiquinone form of flavodoxin from Clostridium MP : Extension of 1.8 A resolution and some comparisons with the oxidized state
(Elsevier, 1977-11-25)
As part of a series of comparisons of the structures of the three oxidation states of flavodoxin from Clostridium MP, phases for the semiquinono form were determined to 2.0 A resolution by isomorphous replacement (m > ...
Loss of sulfite oxidase activity and outer membrane damage in rat hepatic mitochondria during CCl4 poisoning
(Elsevier, 1977-05-09)
The activity of sulfite oxidase increased in intact rat hepatic mitochondria and decreased in solubilized mitochondria during poisoning by CCl4. During acute damage the sulfite oxidase activity of the post-mitochondrial ...
Glucocorticoid inhibition of amino acid transport in rat hepatoma cells
(Elsevier, 1977-10-24)
Dexamethasone rapidly and reversibly inhibits the initial rate of transport of [alpha]-aminoisobutyric acid in rat hepatoma cells in tissue culture. Colcemid and cytochalasin B neither inhibit transport nor interfere with ...
Nature of the repair process associated with the recovery of after exposure to Cd2+
(Elsevier, 1977-02-21)
When different strains of are exposed to Cd2+, the cells accommodate after a long lag and proliferate. The time required for this response depends on the nature of the strain and the supplements in the growth medium. ...
Cellular composition of the human pituitary pars tuberalis as revealed by immunocytochemistry
(Springer-Verlag, 1977-08)
An attempt was made to determine if any of the specialized secretory cell types common to the pars distalis also occur in the pars tuberalis of the human hypophysis. Available for study were 18 specimens of the inferior ...
