Comparison of the Luminex xTAG RVP Fast assay and the Idaho Technology FilmArray RP assay for detection of respiratory viruses in pediatric patients at a cancer hospital.

Respiratory viruses are increasingly recognized as serious causes of morbidity and mortality in immunocompromised patients. The rapid and sensitive detection of respiratory viruses is essential for the early diagnosis and administration of appropriate antiviral therapy, as well as for the effective implementation of infection control measures. We compared the performance of two commercial assays, xTAG RVP Fast (Luminex Diagnostics, Toronto, Canada) and FilmArray RVP (FA RVP; Idaho Technology, Salt Lake City, UT), in pediatric patients at Memorial Sloan-Kettering Cancer Center.

Clinical characterization of human metapneumovirus infection among patients with cancer.

Background: Human metapneumovirus is a recently discovered RNA virus that typically causes respiratory disease in children. It has been linked to severe lower airway disease in hematopoietic stem cell and solid-organ transplant recipients. hMPV infection in a large population of patients with underlying cancer and varying degrees of immunosuppression has not been reported.

Experimentally determining the iR drop in solution at carbon fiber microelectrodes with current interruption and application to single-cell electroporation.

Single-cell electroporation uses microelectrodes, capillaries, or micropipets positioned near single, adherent cells to increase transiently the membrane permeability of the cell. The increased permeability permits, for example, transfection without chemical reagents. When using microelectrodes to apply an electric field to the cell, there is a question of how much voltage to apply.
