It is well-known that the blood properties change with seasons, and especially many reports in respect to change in water content have been made. For example, Kuroda (1) reported that the water content in blood increases in summer, while it decreases in winter. The fact can be explained by the view of Bazett (2), Sjostrand (3), Yoshimura and others (4) that the circulating blood volume, especia...

1. We have not observed gross increases in plasma volume in glomerulonephritis, nephrosis, or nephrosclerosis, even when the concentration of plasma proteins was much below normal. Our results indicate the probability that "hydremic plethora" does not occur. 2. The low protein concentration frequently observed in the plasma in nephritis is not due to increased plasma volume but to a decrease of...

BACKGROUND Kallikreins (KLKs) are a group of 15 secreted serine proteases. Some KLKs are established or candidate cancer biomarkers, but for most the physiological function is unknown. We characterized the protein and mRNA abundance patterns of all 15 KLKs in multiple panels of human tissues and biological fluids. METHODS We used sensitive and specific sandwich-type ELISAs for each KLK. Rever...

We perform the extensive molecular-dynamics simulations of hard-sphere fluids. The stable supercooled liquid state is obtained at high volume fraction on the 15% polydisperse hard-sphere fluids, as the volume fraction is increased. It is shown that the static properties and the dynamic properties, such as, the pressure, the long-time selfdiffusion coefficient, the non-Gaussian parameter and the...

We propose a volume fraction based approach to effectively simulate the miscible and immiscible flows simultaneously. In this method, a volume fraction is introduced for each fluid component and the mutual interactions between different fluids are simulated by tracking the evolution of the volume fractions. Different techniques are employed to handle the miscible and immiscible interactions and...

We present a two-way coupling technique for simulating the complex interaction between hair and fluids. In our approach, the motion of hair and fluids is simulated by evaluating the hydrodynamic forces among them based on boundary handling techniques used in SPH (Smoothed Particle Hydrodynamics) fluids. When hair makes contact with fluids, water absorption inside the hair volume can be simulate...

"Diffuse interface" theories for single-component fluids—dating back to van der Waals, Korteweg, Cahn-Hilliard, and many others—are currently based upon an ad hoc combination of thermodynamic principles (built largely upon Helmholtz's free-energy potential) and so-called “nonclassical” continuum-thermomechanical principles (built largely upon Newtonian mechanics), with the latter originating wi...

The current trend in anaesthesia is to choose crystalloid over colloid fluids for volume replacement in the operating room. Outcome-oriented studies and kinetic analyses have recently provided more insight into how crystalloid infusions should be managed. These fluids have a much better short-term effect on the plasma volume than previously believed. Their efficiency (i.e. the plasma volume exp...

OBJECTIVE To determine whether intraoperative fluid management affects urine output in patients undergoing laparoscopic bariatric operations. DESIGN Randomized controlled trial. SETTING Academic tertiary referral center. PATIENTS Morbidly obese patients scheduled to undergo laparoscopic bariatric procedures. INTERVENTIONS Patients were randomly assigned to receive intraoperatively high ...
