The solubilities of the methyl, ethyl, propyl, and butyl esters of p-hydroxy- and p-aminobenzoates have been determined in propylene glycol:water mixtures. The log of the observed solubility data in propylene glycol:water mixtures was examined for deviations from the following equation: In Xi = f In (Xc) + (1 - f) In (Xw), where Xi is the calculated mole(More)
We adapted a U.S. HIV prevention program to address knowledge gaps and cultural pressures that increase the risk of infection in adolescent Ghanaian girls. The theory-based nine-module HIV prevention program combines didactics and games, an interactive computer program about sugar daddies, and tie-and-dye training to demonstrate an economic alternative to(More)
The Great Plains (GP) region in the United States span from the middle of the continental USA about the 100th meridian westward to the Rocky Mountains and from northern Texas to the Canadian border [1]. The Great Plains covers several states in the central part of the US including Colorado (CO), Kansas (KS), Montana (MT), North Dakota (ND), Nebraska (NE),(More)
An in vitro dynamic method for evaluating the hemolytic potential of intravenous solutions has been developed. The method utilizes an in vitro flow system that provides a reasonable simulation of blood circulation at sites for intravenous injections. Physical variables such as internal diameter of tubing, flow rate of red blood cell (RBC) suspension and(More)
The pharmacokinetics of total and free tiazofurin, an antineoplastic agent, was studied in healthy mongrel dogs following intravenous and oral administration of the drug. The free fraction of tiazofurin was obtained from plasma by an ultrafiltration technique using a micropartition system. Total and free tiazofurin levels were determined by a sensitive high(More)
Fenugreek (Trigonella foenum-graecum L.) is used as medicinal plant in many Asian countries and has been reported to have forage quality similar to alfalfa. Fenugreek is an annual crop and may have the potential to diversify forage production systems in the central High Plains. This study evaluated forage dry matter (DM) production and the nutritive value(More)
