INTRODUCTION Primary care providers can recommend strength training programs to use "Exercise as Medicine," yet few studies have examined the interest of primary care patients in these programs. METHODS We conducted a cross-sectional survey of primary care patients in central Pennsylvania. Interest in participating in free group-based strength training(More)
The results from the meteorology instruments on the Viking 1 lander are presented for the first 4 sols of operation. The instruments are working satisfactorily. Temperatures fluctuated from a low of 188 degrees K to an estimated maximum of 244 degrees K. The mean pressure is 7.65 millibars with a diurnal variation of amplitude 0.1 millibar. Wind speeds(More)
Bean pod tissue (Phaseolus vulgaris L. var. Top Crop) is induced to produce phaseollin when challenged with various microorganisms. The pods react in the same manner when challenged with 9-aminoacridine. This compound also caused an increase in concentrations of phenylalanine ammonia lyase, an enzyme of the phaseollin synthesizing pathway. Both the(More)
A survey of the phosphoribosyltransferase (PRTase) activities in yeast has been accomplished using reversed-phase high-performance liquid chromatographic assay procedures. The following bases were observed to be utilized during phosphoribosyl pyrophosphate (PRibPP)-dependent nucleotide syntheses: adenine, xanthine, hypoxanthine, guanine, uracil, orotate,(More)
A new procedure has been designed for the purification of nicotinate phosphoribosyltransferase and orotate phosphoribosyltransferase from the same baker's yeast extract. Using purified nicotinate phosphoribosyltransferase, the enzyme-catalyzed formation of nicotinate mononucleotide was analyzed using a new high pressure liquid chromatographic assay (Hanna,(More)
