    Notes: : Illinois data from 168 months (1986–1999) were investigated to determine the responses of surface-water and ground-water resources to precipitation. Such responses were generally within the month of occurrence or one to two months later, with recovery being reached another one to three months into the future, depending on season of the year. Although the drought of 1988 immediately impacted surface-water and ground-water resources, the time of recovery was substantially longer compared to those of individual dry months, generally continuing for several months. The extremely wet summer of 1993 resulted in elevated responses in water resources almost immediately, but in this instance continued through the following fall and winter, into the spring of 1994.

    Notes: SYNOPSIS. We demonstrated previously microbodies in Euglena gracilis grown in the dark on 2-carbon substrates. We have now established in Euglena the particulate nature of enzymes known in other organisms to be localized in microbodies (glyoxysomes and leaf peroxisomes). On a linear sucrose gradient the glyoxylate cycle enzymes band together at a nigner equilibrium density (1.20 g/cm3) than mitochondrial marker enzymes (1.17 g/cm3), establishing the existence in Euglena of glyoxysomes similar to those of higher plants. Glyoxylate (hydroxypyruvate) reductase and, under certain conditions, also glycolate dehydrogenase co-band with the glyoxylate cycle enzymes, suggesting that Euglena glyoxysomes, like those of higher plants, may contain peroxisomal-type enzymes. Catalase, an enzyme characteristic of microbodies from a variety of sources, was not detected in Euglena.

    Notes: SYNOPSIS. We demonstrated previously the presence of glyoxysomes containing the glyoxylate cycle enzymes in Euglena gracilis grown in the dark on ethanol. We have now established that the glyoxysomes of Euglena grown on hexanoate also contain the following enzymes of the pathway for β-oxidation of fatty acids: hexanoyl-CoA synthetase, 3-β-hydroxyacyl-CoA dehydrogenase and thiolase. Estimations of specific activities indicate that these enzymes are over 20 times as active in glyoxysomes as they are in mitochondria, suggesting that the β-oxidation of fatty acids occurs almost entirely in Euglena glyoxysomes under these conditions. Thus, the entire portion of the gluconeogenic pathway from fatty acid to succinate is localized in the glyoxysome of Euglena.

    Notes: SYNOPSIS. Electron microscope and time lapse, phase contrast cinematography studies on Babesia equi organisms within equine red blood cells revealed that this hemoprotozoon has two organelles possibly involved with ingestion of nutrients: a cytostome that takes in hemoglobin from the host cell and a tubule that extends from the main body of the parasite through the erythrocyte to the blood plasma and appears to ingest plasma during periods of rapid growth and development.

    Description: Chronic granulomatous disease (CGD) can result from any of four single gene defects involving the components of the superoxide (O−2 ) generating phagocyte nicotinamide adenine dinucleotide phosphate (NADPH) oxidase. We show that transduction of peripheral blood CD34+ hematopoietic progenitors from a p67phox deficient CGD patient with replication defective amphotropic retrovirus encoding p67phox (MFGS-p67phox) significantly corrected the CGD functional defect in phagocyte oxidase activity in vitro. Using a chemiluminescence assay of oxidase activity, we showed that transduced patient CD34+ progenitors differentiating to myeloid cells in culture produced 25% of the total superoxide produced by normal CD34+ progenitors differentiating in culture. A flow cytometric assay of oxidase activity used to assess the oxidase function of individual cells in the cultures indicated that up to 32% of maturing granulocytes derived from transduced CD34+ progenitors from the p67phox CGD patient were oxidase positive with the average level of correction per granulocyte of 85% of that seen with granulocytes in similar cultures of CD34+ progenitors from normal volunteers. Nitroblue tetrazolium dye reduction assays of colonies of transduced progenitors in soft agar indicated that in some studies restoration of oxidase activity occurred in myeloid cells within 44% of granulocyte-erythrocyte-monocyte colonies, and within 28% of the combined group of granulocyte colonies/monocyte colonies/granulocyte-monocyte colonies. These high correction rates were achieved without any selective regimen to enrich for transduced cells. This study provides a basis for development of gene therapy for the p67phox deficient form of CGD.
