Bacterial particle association has important consequences for water-quality monitoring and modeling. Parti-cle association can change vertical and horizontal transport of bacterial cells, as well as patterns of persis-tence and production. In this study, the abundance and particle association of total bacteria and the fe-cal-indicator, Enterococcus, were quantified between June and October 2008 in the lower Hudson River Es-tuary (HRE). Twelve sites were sampled, including mid-channel, near shore, and tributary habitats, plus a sewage outfall. Total bacterial cell counts averaged 9.2 × 109 ± 6.4 × 109 cell·l–1 (1 standard deviation), com-parable to previous sampling in the HRE. Unlike earlier studies, …

Carboplatin and cisplatin are chemotherapeutic agents that are used extensively for treating epithelial ovarian cancer. These drugs can be highly effective, yet tumors are frequently refractory to treatment or become resistant upon tumor relapse. Epigenetic silencing, particularly at promoter regions of genes regulates important cell function and has been associated with all stages of tumor formation and progression and may contribute to therapy response. We analyzed the epigenome of 50 primary ovarian tumors and 12 normal ovarian samples using an array based method previously developed in our lab and associated Affymetrix U133 expression data. We then identified gene candidates that …

Mesenchymal stem cells (MSC) are the progenitor cells to connective tissue cells, epithelial cells, and smooth muscle cells. These cells are currently being investigated as a cellular source for tissue regeneration and repair. The systemic and local tissue environment may have significant influence on the success of such efforts. We hypothesized that elevated glucose and exposure to stress hormones would influence the proliferation of MSC. MSC from the bone marrow of Wistar-Kyoto (WKY) rats were grown under both low glucose (5 mM) and high glucose (20 nM) conditions in the presence and absence of the synthetic glucocorticoid, dexamethasone, and adrenocorticotropin …

Homeostatic stress, such as that which occurs in diabetes, is associated with increased risk for the development of atherosclerosis. Atherosclerotic plaques of the artery wall are associated with both lipid accumulation and fibrous and/or calcified tissue accumulation. Vascular smooth muscle cells (VSMC) are derived from mesenchymal stem cells (MSC) which are capable of differentiating into adipocytes, chondrocytes and osteoblasts. MSC of the bone marrow are pushed toward the chondrogenic and adipogenic phenotypes in the presence of the stress hormones glucocorticoid and adrenocorticotropin (ACTH). This led us to hypothesize that the proliferative VSMC of the Goto-Kakizaki (GK) diabetic rat, when exposed …
