The aqueous outflow system is unique because nowhere else can the pattern of flow of an extravascular fluid be directly observed as it returns to the vascular system. Such observations reveal that aqueous flow both from Schlemm's canal into the aqueous veins and from the aqueous veins into the episcleral veins is pulsatile. Pulsatile aqueous flow mechanisms are observable in vivo not only in no...

CONTEXT Pulsatile lavage is a high-pressure irrigation treatment used increasingly in a variety of health care settings to debride wounds. Infection control precautions are not routinely used during the procedure and are not included in pulsatile lavage equipment package labeling. OBJECTIVES To investigate an outbreak of multidrug-resistant Acinetobacter baumannii and to test the hypothesis t...

AIMS To investigate the effect of central corneal thickness and corneal curvature on intraocular pressure measurements using the pulsatile ocular blood flow tonograph and the Goldmann applanation tonometer, and to assess the agreement between the pulsatile ocular blood flow tonograph and the Goldmann applanation tonometer in intraocular pressure measurement. METHODS 479 subjects underwent int...

The pathway of the vein of hypoglossal canal has not been mentioned in venous origin pulsatile tinnitus. We wished to clarify the possible complications related to this venous variant. We described 2 rare cases of troublesome pulsatile tinnitus associated with prominent vein of hypoglossal canal, which communicates with the jugular bulb and the marginal sinus. Both cases were successfully treat...

BACKGROUND BJUT-II VAD is a novel left ventricular assist device (LVADs), directly implanted into the ascending aorta. The pulsatile support mode is proposed to achieve better unloading performance than constant speed mode. However, the hemodynamic effects of this support mode on the aorta are still unclear. The aim of this study was to clarify the hemodynamic effects BJUT-II VAD under pulsatil...

The aim of this study was to investigate the development of pulsatile GnRH secretion by GnRH neurones in primary cultures of olfactory placodes from ovine embryos. Culture medium was collected every 10 min for 8 h to detect pulsatile secretion. In the first experiment, pulsatile secretion was studied in two different sets of cultures after 17 and 24 days in vitro. In the second experiment, a se...

he advent of cardiopulmonary bypass (CPB) has enabled cardiovascular surgeons to perform complex, life-saving procedures with relative ease while protecting end-organ function. Altering the normal pulsatile blood flow to non-pulsatile continuous flow has raised concerns over potential detrimental hemodynamic and physiologic consequences. Concerns over long-term non-pulsatile flow drove the desi...

BACKGROUND For blood purification systems using a semipermeable membrane, the convective mass transfer by ultrafiltration plays an important role in toxin removal. The increase in the ultrafiltration rate can improve the toxin removal efficiency of the device, ultimately reducing treatment time and cost. In this study, we assessed the effects of pulsatile flow on the efficiency of the convectiv...

transradial coronary angiography has been known as an alternative to the transfemoral approach with fewer serious complications. radial artery pseudoaneurysms present as a rare complication of transradial catheterization. although some methods have been applied for the obliteration of pseudoaneurysms, the use of radial bands such as the tr band ® (terumo medical corporation, somerset, nj) is a ...
