Background: Combination of glycation and oxidation is associated with diabetes mellitus. The aim of this study was to clarify the effect of glycated proteins in presence of transition metal ions on production of reactive oxygen species (ROS) in rat hepatocyte suspension.  Methods: Glycated albumin was prepared by incubation of bovine serum albumin with 100 mM glucose in 0.3 M phosphate buffer a...

The in vitro differentiation of ES cells towards a hematopoietic cell fate is useful when studying cell populations that are difficult to access in vivo and for characterizing the earliest genes involved in hematopoiesis, without having to deal with embryonic lethalities. The ES/OP9 co-culture system was originally designed to produce hematopoietic progeny, without the over production of macrop...

glial cell line-derived neurotrophic factor (gdnf) plays important roles not only for the differentiation of neurons during normal development but also for the survival and recovery of many populations of mature neurons. the effect of traumatic brain injury (tbi) on the expression of gdnf is currently unknown. to determine if there is alteration in gdnf after tbi we examined the effect of contr...

Circulating tumor cells (CTCs) are essential for the establishment of distant metastasis. Numerous studies have characterized CTCs as metastatic precursors; however, the molecular nature of CTCs has not been completely revealed yet due to the low number of CTCs in the blood stream. As an alternative approach, we developed a long-term suspension cell culture model using human breast cancer cell ...

By using the cell density, cell viability, Pro-UK activity, specific consumption rate of glucose (q(glc)), specific production rate of lactate (q(lac)), yield of lactate to glucose (Y(lac/glc)) and as the evaluation indexes, the growth and metabolism characteristics of pro-urokinase (Pro-UK) expressing CHO cells in serum-free suspension batch culture were examined and compared to those in serum...

A complete analysis of the translational and rotational modes of a model lateral suspension is presented. The derived formulae quantify spurious-mode resonant frequencies for cross-axis translation and rotation, and on-axis translation, and can provide very simple expressions for the rejection ratios in terms of the geometry of the suspensions. It is shown that the introduction of intermediate ...

The aim of this work was to develop a soap-based method for the isolation poly(3-hydroxybutyrate) from bacterial biomass. consisted adding soap derived waste cooking oil concentrated (25%) biomass suspension, heating and centrifugal separation. Purity above 95% could be achieved with soap:cell dry mass ratios at least 0.125 g/g, making comparable other surfactant-based protocols. Molecular weig...
