Recasting nonlinear differential equations as S-systems: a canonical nonlinear form
(Elsevier, 1987-11)
An enormous variety of nonlinear differential equations and functions have been recast exactly in the canonical form called an S-system. This is a system of nonlinear ordinary differential equations, each with the same ...
Molecular characterization and genetic mapping of DNA sequences encoding the Type I chlorophyll a/b-binding polypeptide of photosystem I in Lycopersicon esculentum (tomato)
(Kluwer Academic Publishers; Martinus Nijhoff Publishers ; Springer Science+Business Media, 1987-05)
We report the isolation and characterization of a tomato nuclear gene encoding a chlorophyll a/b-binding (CAB) protein of photosystem I (PSI). The coding nucleotide sequence of the gene, designated Cab -6B, is different ...
Biochemical systems theory and metabolic control theory: 1. fundamental similarities and differences
(Elsevier, 1987-10)
Biochemical Systems Theory (BST) was developed in the late 1960s to explicate the integrated behavior of intact biochemical systems--specific dynamic behavior as well as general principles of design--in relation to the ...
Mechanisms for the stimulatory and inhibitory effects of carbamoylcholine on canine gastric D-cells
(Elsevier, 1987-08-31)
We have previously reported that carbamoylcholine (carbachol), a recognized inhibitor of somatostatin release from D-cells, can act as stimulant following pretreatment of cells with pertussis toxin. In the present studies ...
Cyclosporine augments reactivity of isolated blood vessels
(Elsevier, 1987-06-29)
Administration of cyclosporine (CS) as an immunosuppressive agent in clinical transplantation is associated with multiple side effects including nephrotoxicity and hypertension. These two effects could be related in that ...
NH2-Terminal of gastrin-17 in duodenal ulcer disease: Identification of progastrin-17
(Elsevier, 1987-07-31)
Serum gastrin concentrations were measured using antisera with specificity for the carboxyl and amino terminus of gastrin-17 in 50 healthy subjects and 18 patients with active duodenal ulcer disease (DU). The amino terminal ...
The tomato Cab -4 and Cab -5 genes encode a second type of CAB polypeptides localized in Photosystem II
(Martinus Nijhoff, The Hague/Kluwer Academic Publishers; Martinus Nijhoff Publishers ; Springer Science+Business Media, 1987-03)
The photosynthetic apparatus of plant chloroplasts contains two photosystems, termed Photosystem I (PSI) and Photosystem II (PSII). Both PSI and PSII contain several types of chlorophyll a/b-binding (CAB) polypeptides, at ...
Stimulation of prostaglandin E2 and thromboxane B2 production by human monocytes in response to interleukin-2
(Elsevier, 1987-08-31)
Interleukin 2 (IL-2) is a potent lymphokine involved in the regulation of immune responses and is classically regarded as a stimulus for the activation and growth of T-cells. Recent reports have demonstrated the IL-2 ...
Atrial natriuretic hormone is not elevated during dopamine induced natriuresis
(Elsevier, 1987-05-18)
To evaluate the possibility that atrial natriuretic hormone (ANH) is involved in dopamine induced natriuresis and diuresis, we studied five normal male volunteers. Each was studied on two occasions. During the first two ...
