Mesenchymal stromal cells (MSCs) have the potential to treat many myocardial diseases. We investigated whether these multipotent stem cells derived from bone marrow could be administered safely into the coronary circulation of healthy dogs. We injected about 0.5 million cells per kg bodyweight of early passage autologous MSCs into the left circumflex(More)
The primary sequence of the microtubule-associated protein tau contains multiple repeats of the sequence -X-Ser/Thr-Pro-X-, the consensus sequence for the proline-directed protein kinase (p34cdc2/p58cyclin A). When phosphorylated by proline-directed protein kinase in vitro, tau was found to incorporate up to 4.4 mol of phosphate/mol of protein. Isoelectric(More)
Depolarization of cultured bovine adrenal chromaffin cells with KCl increased the activity of a proline-directed protein kinase that phosphorylates tyrosine hydroxylase. Characterization of the KCl-activated protein kinase activity revealed that it shared similar biochemical and chromatographic properties with the microtubule-associated protein-2(More)
Four different forms of human epidermal growth factor (h-EGF) are found in the culture medium of a recombinant strain of Saccharomyces cerevisiae. These forms were characterized after purification using reverse-phase high-performance liquid chromatography. The most abundant form of secreted recombinant h-EGF has leucine at the carboxyl terminus and is(More)
AIMS To design and investigate a recombinant expression system producing a therapeutically important glycoprotein, human erythropoietin (rHuEPO), by Pichia pastoris. METHODS AND RESULTS EPO cDNA was cloned into pPICZalphaA for expression under control of AOX1 promoter and fused, on the amino-terminal end, with a polyhistidine tag for rapid purification. A(More)
An expression system in Pichia pastoris for the production and purification of recombinant human growth hormone (rHGH) was designed and implemented. hGH cDNA sequence was cloned into pPICZalphaA vector under the control of AOX1 promoter, which included a polyhistidine-tag on the amino terminal end to enable affinity purification and a target site for Factor(More)
The objective of this article is to test the effectiveness of a multifaceted exercise and nutritional education intervention for chronically ill, community-dwelling older adults. A pre/post cohort design was implemented with measures of physical activity, fitness, depression, and anthropometry collected via 4-month in-person interview and telephone(More)
