Next, in the transient blood flow, a sudden increase in the blood flow-rate induces the transient behaviors of the blood flow in the bridge channel. Here, the elasticity (or characteristic time) of blood can be quantitatively measured by analyzing the dynamic movement of FK866 blood in the bridge channel. The regression formula (A(Blood) (t) = A(alpha) + A(beta) exp [-(t - t(0))/lambda(Blood)]) is selected

based on the pressure difference (Delta P = P-A – P-B) at each junction (A, B) of both side channels. The characteristic time of blood (lambda(Blood)) is measured by analyzing the area (A(Blood)) filled with blood in the bridge channel by selecting an appropriate detection window in the microscopic images captured by a high-speed camera (frame rate = 200 Hz, total measurement time = 7 s). The elasticity of blood (G(Blood))

is identified using the relationship between the characteristic time Acalabrutinib chemical structure and the viscosity of blood. For practical demonstrations, the proposed method is successfully applied to evaluate the variations in viscosity and elasticity of various blood samples: (a) various hematocrits form 20% to 50%, (b) thermal-induced treatment (50 degrees C for 30 min), (c) flow-induced shear stress (53 +/- 0.5 mL/h for 120 min), and (d) normal rat versus spontaneously hypertensive rat. Based on these experimental demonstrations, the proposed method can be effectively used to monitor variations in viscosity and elasticity of bloods, even with the absence of fully integrated sensors, tedious labeling and calibrations.

“We have investigated magnetic properties of the heavy fermion system Ce1-xGdxCoSi3 (0 <= x <= 1) via specific heat and electrical resistivity measurements. The specific heat shows antiferromagnetism at 9 K for GdCoSi3 (x = 1.0). With increasing Ce concentration, T-N linearly decreases and is suppressed at x = 0.1. An anomalous hump in specific heat was found below the ordering temperature for x >= 0.4. For x = 0.1, non-Fermi-liquid behavior was found in electrical

resistivity and -ln T divergence in C/T below 3 K. Our results indicate that x = 0.1 is a quantum critical point. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3076604]“
“Blood viscosity has been considered as one of important biophysical parameters for effectively monitoring variations in physiological and pathological conditions of circulatory disorders. Standard previous methods make it difficult to evaluate variations of blood viscosity under cardiopulmonary bypass procedures or hemodialysis. In this study, we proposed a unique microfluidic device for simultaneously measuring viscosity and flow rate of whole blood circulating in a complex fluidic network including a rat, a reservoir, a pinch valve, and a peristaltic pump.
