Only five of the nine subunits of human eukaryotic translation initiation factor 3 (eIF3) have recognizable homologs encoded in the Saccharomyces cerevisiae genome, and only two of these (Prt1p and Tif34p) were identified previously as subunits of yeast eIF3. We purified a polyhistidine-tagged form of Prt1p (His-Prt1p) by Ni2+ affinity and gel filtration(More)
Irradiation of intact or EDTA-dissociated L-cell polyribosomes with 254 nm UV light at doses of 1-2 x 10(5) ergs/mm2 extensively crosslinks mRNA to proteins. The crosslinked mRNA-protein complexes can be isolated on the basis of buoyant density in urea-containing CS2SO4 gradients that dissociate non-covalent complexes. Crosslinking of mRNA can also be(More)
This double-blind study compared the clinical safety and parasitologic efficacy of single-dose regimens of diethylcarbamazine (DEC) and ivermectin for treatment of bancroftian filariasis in Papua New Guinea. Five groups of 10 men each with mean levels of parasitemia ranging from 2,985 to 5,185 microfilariae (mf)/ml were given DEC (6 mg/kg of body weight one(More)
Previous work in our laboratory showed that L-sorbose utilization in Candida albicans is subject to a novel form of regulation which involves a reversible increase or decrease in the copy number of chromosome 5. Furthermore, the structural gene SOU1 is required for L-sorbose utilization and encodes a member of the short chain dehydrogenase family. However,(More)
Previous work in our laboratories (Slobin, L. I., and Greenberg, J.R. (1988) Eur. J. Biochem. 173, 305-310) showed that messenger ribonucleoprotein (mRNP) particles possess a polypeptide component of approximately 62 kDa that appears to share a common epitope with eucaryotic elongation factor 1 alpha (EF-1 alpha). We report here that the previously(More)
OBJECTIVE The outcomes of the California Public Employees Retirement System's Health Matters program, a replication of a health promotion and fitness program known as the Senior Wellness Program (SWP), are reported. METHOD A randomized controlled design (n = 504) was used. Eligibility included one or more qualifying chronic health conditions, age 65 or(More)
A reversible decrease or increase of Candida albicans chromosome copy number was found to be a prevalent means of survival of this opportunistic pathogen, under conditions that kill cells or inhibit their propagation. The utilization of a secondary carbon source, l-sorbose, by reversible loss of chromosome 5, serves as a model system. We have determined(More)
