Ornithine decarboxylase activity in retinal explants of goldfish undergoing optic nerve regeneration
(Elsevier, 1981-06)
Retinal explants cultured in the presence of fetal calf serum (FCS) exhibit an increase in the activity of ornithine decarboxylase which is maximal several hours after explanation. The measured activity of this enzyme is ...
A game to help students comprehend enzyme structure and mechanism of action
(Elsevier, 1976-01)
Uridine Metabolism in the Goldfish Retina During Optic Nerve Regeneration: Whole Retina Studies
(Blackwell Publishing Ltd, 1981-03)
Accumulation of radioactivity from [ 3 H]uridine in incubations of whole goldfish retinas is increased in the ipsilateral retina during a period of regeneration that follows unilateral optic nerve crush. Brief incubations ...
Properties of the tryptophan residue in rabbit liver microsomal cytochrome P-450 isozyme 2 as determined by fluorescence
(Elsevier, 1985-04-30)
Cytochrome P-450 isozyme 2 from rabbit liver microsomes fluoresces upon excitation at 295 nm due to the single tryptophyl residue (Trp121) in the protein. The fluorescence spectrum, which is not altered by the presence of ...
Protection by Vitamin B 2 Against Oxidant-Mediated Acute Lung Injury
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1999-10)
The effect of vitamin B 2 (riboflavin) on oxidant-mediated acute lung injury has been examined in three different rat models. Pulmonary injury was induced by intravenous injection of cobra venom factor (CVF), by the ...
Kinetics of Carboxylmethylation of the Charge Isoforms of Myelin Basic Protein by Protein Methyltransferase II
(Blackwell Publishing Ltd, 1989-12)
The charge isoforms (C1-C5) of bovine myelin basic protein (MBP) were used as substrates for the rat brain enzyme protein carboxylmethyltransferase (PM II). The objective of these experiments was to ascertain whether the ...
Griffonia simplicifolia I lectin mediates macrophage-induced cytotoxicity against Ehrlich ascites tumor
(Elsevier, 1982-07-15)
The concurrent administration of Griffonia simplicifolia lectin into the peritoneal cavity of mice has been reported to protect them from challenge with Ehrlich ascites tumor cells. This study demonstrates that the GS I ...
Modification of cell membrane in variants of chinese hamster cells resistant to abrin
(Elsevier, 1980-10)
Stable and heritable variants of Chinese hamster ovary (CHO) cells which are resistant to different levels (0.1, 1.0 and 10 [mu]g/ml) of the toxin abrin have been isolated and characterized. The frequency of resistant ...
Protein-carbohydrate interaction : VIII. A turbidimetric method for the analysis of -mannose
(Elsevier, 1967-08)
A unique, spectrophotometric method for the quantitative of -mannose in the presence of other sugars is described. The procedure depends on the degree to which the turbidity formed on interaction of concanavalin A with ...
A structural comparison of the A and B subunits of Griffonia simplicifolia I isolectins
(Elsevier, 1984-02-15)
A structural comparison between the A and B subunits of the five tetrameric Griffonia simplicifolia I isolectins (A4, A3B, A2B2, AB3, B4) was undertaken to determine the extent of homology between the subunits. The first ...
