Catheter-related candidemia caused by Candida haemulonii in a patient in long-term hospital care.

Candida haemulonii, one of the non-albicans Candida species, is an emerging yeast pathogen that is known to be resistant to amphotericin B and other antifungal agents such as azoles. These anti-fungal agents have often been associated with clinical treatment failure, so no treatment regimen has been clearly established for invasive C. haemulonii infections.

Characteristics of blood flow resistance under transverse vibration: red blood cell suspension in Dextran-40.

Vibration under shear flow causes the reduction of flow resistance for shear-thinning fluids. The present study investigates the effect of vibration on the flow resistance of a nonaggregating red blood cell (RBC) suspension with a newly designed pressure-scanning capillary viscometer (PSCV). The PSCV was originally designed to measure non-Newtonian viscosity continuously over a range of shear rates at a time, which was slightly modified and used for the present study.
