Trout are of interest in defining the relationship between fluid and salt balance on cardiovascular function because they thrive in freshwater (FW; volume loading, salt depleting), saltwater (SW; volume depleting, salt loading), and FW while fed a high-salt diet (FW-HS; volume and salt loading). The effects of chronic (>2 wk) adaptation to these three protocols on blood volume (51Cr red cell sp...

The phenomenon of apparent slip in micro-channel flows is analyzed by means of a two-phase mesoscopic lattice Boltzmann model with non-ideal fluid–fluid and fluid–wall interactions. Analytical solutions of the weakly inhomogeneous hydrodynamic limit of this model are successfully compared with numerical simulations and show that the present mesoscopic approach is capable of filling the gap betw...

Predicting fluid responsiveness, the response of stroke volume to fluid loading, is a relatively novel concept that aims to optimise circulation, and as such organ perfusion, while avoiding futile and potentially deleterious fluid administrations in critically ill patients. Dynamic parameters have shown to be superior in predicting the response to fluid loading compared with static cardiac fill...

A 40-year-old man had low back pain and left leg pain for 2 months. MR disclosed a cystic tumor filling the spinal canal. On T2-weighted images (Fig 1A), fluid in the cyst showed a fluid-fluid level. On contrast with gadopentate dimeglumine (Fig 1B), of the cyst wall showed enhancement. At surgery, an intradural cystic mass was found. Fluid in the mass was a combination of two different fluids,...

Research has shown that overhanging dental restorations and subgingival margin placement play an important role in providing an ecologic niche for periodontal pathogens. Periodontal attachment loss and inflammation associated with overhanging restorations were reported extensively in the literature. A total of 15 overhanging amalgam restorations were selected and the plaque index (PI), Gingival...

Appropriate use of fluid infusion in cardiac surgery patients is of primary importance in the perioperative period in order to optimize cardiac output and oxygen delivery and to reduce the use of vaspressors and inotropes. Fluid infusion is usually triggered by arterial hypotension, low urine output and signs of inadequate tissue oxygenation (e.g. hyperlactatemia). This general rule, however, m...

In this paper, we describe a method to load a microfluidic device, the SlipChip, via dead-end filling. In dead-end filling, the lubricating fluid that fills the SlipChip after assembly is dissipated through the gap between the two plates of the SlipChip instead of flowing through an outlet at the end of the fluidic path. We describe a theoretical model and associated predictions of dead-end fil...
