Predictors of Time to Viral Load Suppression of Adult PLWHIV on ART in Arba Minch General Hospital: A Follow up Study.

Background: Access to antiretroviral drugs for all infected persons in need is a global health priority. The viral load and CD4 counts should be monitored regularly. The plasma viral load should be reduced by as much and for as short as possible.

A multiplex high-throughput gene expression assay to simultaneously detect disease and functional markers in induced pluripotent stem cell-derived retinal pigment epithelium.

There is continuing interest in the development of lineage-specific cells from induced pluripotent stem (iPS) cells for use in cell therapies and drug discovery. Although in most cases differentiated cells show features of the desired lineage, they retain fetal gene expression and do not fully mature into "adult-like" cells. Such cells may not serve as an effective therapy because, once implanted, immature cells pose the risk of uncontrolled growth.

Measurement of absolute flow velocity vector using dual-angle, delay-encoded Doppler optical coherence tomography.

Single-beam laser Doppler measurements of flow velocity are only sensitive to the velocity component parallel to the optical axis. We describe a simple modification to a standard Doppler optical coherence tomography (OCT) system using a single sample beam that provides velocity information from multiple angles within the beam. By introducing a glass plate midway into the OCT beam path, the sample beam is divided into several components, each with a different group delay and each providing a separate interferogram with its own effective Doppler angle.
