Cloning and characterization of tomato leaf senescence-related cDNAs
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-03)
Senescence-related cDNA clones designated SENU1, 4, 5 (senescence up-regulated) and SEND32, 33, 34, 35 and 36 (senescence down-regulated) isolated from a tomato leaf cDNA library [9] were characterized. Southern analysis ...
The amino acid substitution and some chemical properties of a variant human erythrocyte carbonic anhydrase: Carbonic anhydrase Id Michigan
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1967-09)
Carbonic anhydrase Id Michigan , an electrophoretic variant of human red cell carbonic anhydrase I, was purified from erythrocytes obtained from an individual heterozygous for the trait. Primary structural analysis indicates ...
Structure‐guided insights on the role of NS1 in flavivirus infection

Monovalent cations (Na+, K+, Cs+) inhibit calcium activation of photosynthetic oxygen evolution
(Elsevier, 1989-02-13)
In the absence of the 17 and 23 kDa water-soluble polypeptides, the oxygen-evolving complex of photosystem II requires addition of Cl- and Ca2+ to maximize rates of oxygen evolution activity. We have found that monovalent ...
The structures of the glia and of the synapses in the sympathetic chain of man
(Springer-Verlag, 1960-07)
Del Rio Hortega teilte die Glia der sympathischen und spinalen Ganglien in 2 Gruppen ein: 1. die perisomatische Glia, welche das Perikaryon der Parenchymzellen mit 2 übereinandergelagerten Schichten umgibt und 2. periaxonale ...
Non-visual functions of crustacean eyestalk ganglia
(Springer-Verlag, 1971-03)
Ablation experiments demonstrated that in several crustacean groups, the proximal eyestalk ganglia are important in a variety of behavior patterns: 1. Chemical elicitation of feeding via the antennules is altered in lobsters, ...
Drug inhibitable ecto-ATPase in leukocytes
(Elsevier, 1975-05-01)
In rat leukocytes, the total ATP-hydrolyzing activity was highest when determined in cells with an intact plasma membrane. The ecto-ATPase, exhibiting a Km for ATP of 0.3 mM, was inhibited 30% by sulfhydryl reagents, whereas ...
Differing calcium requirements for regulatory effects of ATP, ATP[gamma]S and adenosine on O2 responses of human neutrophils
(Elsevier, 1988-07-29)
In formyl peptide stimulated human neutrophils the enhancement of O2 responses by ATP and ATP[gamma]S requires extracellular calcium. In contrast, the inhibitory effects of adenosine are independent of a calcium requirement. ...
Herpes simplex virus thymidine kinase gene is stably maintained and expressed in cells transformed by protoplast fusion
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1984-03)
We examined a series of transformed cell lines resulting from transfer of the herpes simplex virus type 1 thymidine kinase gene to Ltk − cells by protoplast fusion gene transfer. We show that multiple copies of the ...
Estrogen induction of ornithine aminotransferase in rat kidney slices
(Elsevier, 1978-06-14)
Immunologic titration of kidney extracts from control and estradiol-injected rats with anti-ornithine aminotransferase serum shows that the hormone induces the enzyme by increasing its concentration in the kidney. The ...
