In the nuclear genome of Saccharomyces cerevisiae, simple, repetitive DNA sequences (microsatellites) mutate at rates much higher than nonrepetitive sequences. Most of these mutations are deletions or additions of repeat units. The yeast mitochondrial genome also contains many microsatellites. To examine the stability of these sequences, we constructed a reporter gene (arg8(m)) containing out-o...

The effect of stability of achievement goals on learning behaviors and outcomes has yet to be explored. This study examined how adolescents’ achievement goals...

Interleukin 2 (IL-2) therapies have antitumor activities against several neoplasms. In vitro these activities are enhanced by beta-interferon (IFN-beta). Therefore, we initiated a Phase I trial with a combination of IL-2 and IFN-beta three times weekly. The IFN-beta was administered i.v. Initially, the IL-2 was administered s.c. However, neutralizing antibody to the IL-2 developed in five patie...

This paper evaluates the impacts of new housing developments funded with the Low Income Housing Tax Credit (LIHTC), the largest federal project based housing program in the U.S., on the neighborhoods in which they are built. A discontinuity in the formula determining the magnitude of tax credits as a function of neighborhood characteristics generates pseudo-random assignment in the number of lo...

The recording capability of a microelectrode array in the cat dorsal root ganglion (DRG) was studied in 11 acute experiments, 373 single, discriminable sensory units were recorded on 587 electrodes (0.64 units/electrode). Sensory action potentials as large as 1750 microV were obtained (mean=132 microV). These were comparable to literature reports of the best DRG extracellular recordings made wi...

The recruitment order of motor units was studied with an electromyographic technique for secure identification of single motor unit potentials. It has been shown in previous studies of normal subjects that the recruitment order in sustained voluntary contraction is predominantly stable, and that motor units which increase slowly in discharge rate with increasing contraction strength and which a...
