Perpetuating Inequality by Taxing Wealth

This Article attempts to correct this shortcoming in the progressive argument by returning narrative to its central place in the estate tax debate. Drawing on psychological insights, I hope to underscore the difficulty of the effort to preserve progressive taxation and combat wealth inequality

The Effects of Thyroxine on Ribonucleic Acid Content in the Brain of Rana Pipiens Tadpoles

Considerable knowledge concerning RNA formation is known for developing embryos of the frog, Rana pipiens, and the clawed toad, Xenopus laevis. Esper (1962) employed the cytophotometric method of determining the quantity of RNA in pronephric, epidermal, and endodermal cells in haploid and diploid embryos of Rana pipiens (Shumway Stage 24). The cytophotometric measurement revealed that the concentration of RNA per unit area of cytoplasm is the same for haploid and diploid embryos studied. However, cell volume determination indicated that diploid cells of each tissue are twice the volume of haploid cells. The total amount of RNA in the diploid cell is therefore twice the volume of haploid cells. The study of RNA systhesis in synchronized type cells by Klevez and Stubblefield (1967a) revealed an increase in the rate of RNA synthesis after the synthesis of only a small portion of the DNA. They suggested that this phenomenon was the result of replication of functional DNA templates in the cell. Klevez and Stubblefield (1967b) conducted a similar study on synchronized mammalian cell cultures with similar findings; that most of the DNA involved in transcription was replicated in the first third of the DNA synthesis period. Therefore the rates of RNA and protein synthesis increased because of the doubling of the active template population of each cell. Since the literature revealed a marked increase in mitotic activity in the neural axis, which is accompanied by an increase in DNA, during metamorphic climax and following administration of exogenous thyroxine, it seemed feasible to investigate further the role of the thyroxine in stimulating nucleic acid synthesis in the brain of Rana pipiens larvae, with emphasis on the quantity of DNA and RNA produced

Equal Protection of Law—Racial Restrictive Covenants—Damages for Breach Allowed

Compulsory Home Repair Laws

In recent years legislative bodies at various levels of government have recognized the need for legally requiring the maintenance of housing at certain minimum standards. Such regulation has been deemed necessary because of the deterioration experienced by practically every major city in America. This deterioration causes a downward spiral usually resulting in complete blight in the deteriorating area. The first step toward blight is slight deterioration followed by neglect of repairs by owners and landlords (the latter neglect is an attempt to maintain a high return on investment, the former because of loss of faith in the quality of the neighborhood). In the final analysis purchasers who might have invested in and maintained the neighborhood abandon the area and it is left to rot and die

The Effect of Ergosterol on the Desaturation Of 14C-Labeled Oleic Acid in Tetrahymena

The ciliated protozoan Tetrahymena pyriformis-Strain W desaturated 14C-labeled fatty acid substrate in both sterol supplemented (ergosterol) and nonsupplemented cultures. Cis-octadecenoic acid (14C-9-18:1), when added to the medium during the log phase of growth, was incorporated into the cells and also desaturated at the Δ6 and Δ12 positions. The 14C labeled substrate and products, linoleate (9,12-18:2) or linolenate (6,9,12-18:3) were recovered and separated by silver-nitrate Unisil column chromatography. Initially, recovery of 14C compounds varied widely when expressed as the percent of total counts per minute recovered from column chromotography, and a variety of procedural modifications were required before a reproducibly significant effect of the foreign sterol on desaturation of substrate was demonstrated. Addition of ergosterol to the growth medium of Tetrahymena leads to incorporation of the foreign sterol within cell membranes and supression of synthesis of the native compound tetrahymanol, as well as to changes in the fatty acid compositions of several major classes of membrane lipid. Alteration of fatty acid composition is thought to represent a regulatory mechanism whereby optimum membrane fluidity is maintained when the slightly dissimilar foreign sterol is incorporated into the phospholipid bilayer of the membranes. The present study, using several different conditions of growth temperature, culture size and ergosterol concentrations, is an attempt to provide evidence supporting a regulatory role for membrane-bound sterol. The regulatory mechanism hypothesized is allosteric modification of an enzyme or enzymes involved in the synthesis of fatty acids contained in membrane phospholipids by the membrane-bound sterol. Such a mechanism could account, at least in part, for the balance between sterol and fatty acid content of membranes. The data presented here show that a statistically significant decrease in desaturation of 14C-labeled 9-18:1 can be demonstrated in Tetrahymena cell cultures whose membranes contain the foreign sterol ergosterol when compared to cell cultures not receiving sterol supplementation when growth temperature is maintained at 20°
