Drug Screening Using Normal Cell and Cancer Cell Mixture in an Automated 3D Cell Culture System.

Three-dimensional (3D) cell culture creates a more physiologically relevant environment for enhanced drug screening capabilities using microcarriers. An automated 3D system that integrates robotic manipulators, liquid handling systems, sensors, and environment control systems has the capacity to handle multiple samples in parallel, perform repetitive tasks, and provide real-time monitoring and analysis. This chapter describes a potential 3D cell culture drug screening model by combining renal proximal tubule cells as a representative normal cell line with cancer cell lines.

Toward a new clinical pragmatism: method in clinical ethics consultation.

In this paper, I leverage the pragmatist tradition in philosophy, the collective wisdom of scholarship in clinical ethics consultation, and earlier attempts to apply pragmatism in clinical ethics to develop a new vision of clinical ethics practice called New Clinical Pragmatism. It argues that clinical ethics methodology, from the New Clinical Pragmatist's perspective, amounts to the recommendation that consultants should customize a methodological approach, drawing on the various available methods, depending on the demands of the specific case, and should avoid attempts to identify a 'true' methodology but to the incoherence and inevitable failure of those attempts. I argue that pragmatism's emphasis on practical wisdom and experimentation allow the New Clinical Pragmatist to do this while avoiding irrationality in choosing methods.

Renal autocrine neuropeptide FF (NPFF) signaling regulates blood pressure.

The kidney and brain play critical roles in the regulation of blood pressure. Neuropeptide FF (NPFF), originally isolated from the bovine brain, has been suggested to contribute to the pathogenesis of hypertension. However, the roles of NPFF and its receptors, NPFF-R1 and NPFF-R2, in the regulation of blood pressure, via the kidney, are not known.

Caveolin-1, a Determinant of the Fate of MCF-7 Breast Cancer Cells.

Background: The scaffolding protein, caveolin-1 (Cav-1), participates in multiple cellular functions including promotion of sodium excretion from the kidney. Loss of expression of Cav-1 is associated with tumorigenesis of various types of cancer. We have shown the potential link between hypertension and breast cancer via abnormal function of the G protein-coupled receptor kinase type 4 (GRK4).
