Erratum Unfortunately, the original version of this article [1] contained an error. There are two references in the text to the threshold for defining VAP as greater than 10^4 colony forming units/ml. These should read greater OR EQUAL to 10^4 colony forming units/ml. The error is in the abstract and in the intervention sections. In the abstract, please replace: Patients with clinically suspect...
Medium conditioned in the presence of human HUT-102 T-cell line cells contains activities stimulating human mixed (colony-forming unit, erythroid, granulocyte, macrophage, megakaryocyte) and erythroid (burst-forming unit, erythroid) colony formation in methylcellulose in vitro and granulocyte colony formation in diffusion chambers in mice. The stimulatory effect of HUT-102-conditioned medium on...
The fungal population and distribution of aflatoxin-producing fungi in 30 samples of imported almond powder products purchased from retail markets were examined in this study. Total counts of fungi ranged from under 1.0 x 10 colony-forming units (CFU)/g to 8.5 x 10(3) CFU/g as determined with the dilution plating technique. The predominant fungi in the mould-contaminated almond samples were Asp...
On addition of DMSO, the MEL cell line TSA8 becomes committed into erythroid progenitor cells (CFU-E) which can form differentiated colonies in the presence of erythropoietin. To understand the mechanism of cellular commitment, the number and the affinity of the receptors for erythropoietin were estimated. The affinity of the receptors did not change before or after induction. The number of rec...
Culturability and coexistence of bacterioplankton exhibiting different life strategies were investigated in the Baltic Sea and Skagerrak Sea. Bacterial numbers were estimated using a dilution-to-extinction culturing assay (DCA) and calculated as the most probable number, based on six different methods to detect bacterial growth in the DCA. Irrespective of the method used to detect growth, the f...
In this study, we characterized the self-renewal capability, multi-lineage differentiation capacity, and clonogenic efficiency of human dental pulp stem cells (DPSCs). DPSCs were capable of forming ectopic dentin and associated pulp tissue in vivo. Stromal-like cells were reestablished in culture from primary DPSC transplants and re-transplanted into immunocompromised mice to generate a dentin-...
Lung colony-forming ability of clones isolated from a fibrosarcoma was examined by i.v. injection of the cells cultured in vitro. The clones were heterogeneous in their lung colony-forming ability, demonstrating variability of this malignant characteristic.
Erythroid progenitors from 1 8 fetal livers (7-1 5-wk gestational period) and 1 3 normal adult marrows were grown in methylcellubose cultures containing erythropoietin (Ep) and burst-enhancing factor(s) (BEF). Additional experiments were carried out on 1 fetal, 1 5 neonatal. and 26 adult blood specimens. Three classes of progenitors (primitive or mature erythroid burst-forming unit(s). P-BFU-E....
