Beating the cold: the functional evolution of troponin C in teleost fish.
The sensitivity of the cardiac myocyte contractile element for Ca(2+) decreases with temperature. As myocyte contractility is regulated by changes in cytosolic [Ca(2+)], this desensitizing effect represents a challenge for temperate fish such as the rainbow trout, Oncorhynchus mykiss, living in environments where temperatures are low and variable. To allow cardiac function in a temperate enviro...
متن کاملThe clinical and cost-effectiveness of pulsatile machine perfusion versus cold storage of kidneys for transplantation retrieved from heart-beating and non-heart-beating donors.
OBJECTIVES To evaluate the clinical and cost-effectiveness of machine perfusion (MP) compared to cold storage (CS), as a means of preserving kidneys prior to transplantation. Transplantation of kidneys from both heart-beating donors (HBDs) and non-heart-beating donors (NHBDs) is considered. Finally to review whether the use of MP can allow valid testing of kidney viability prior to transplantat...
متن کاملBeating the Standard Model *
Although our beloved standard model of quarks and leptons offers a complete, consistent and correct description of most particle phenomena, lots of vexing questions remain unanswered, such as: Why are the gauge group and the fermion masses what they are? Why three families of quarks and leptons? What breaks electroweak symmetry? How about gravity? Leaving such profound meta-questions to supersy...
متن کاملA Hybrid Method to Deformation Force of High-speed Cold Roll-beating Forming
ABSTRCT: High-speed cold roll-beating forming technique is a new near-net plastic forming method that the intermittent high-speed roll-beating is used to achieve dynamic impact local loading, and that is fast, transient, high impact, large deformation of the complex forming process. For this forming process, the main stress method is employed to derive an analytic formula for the deformation fo...
متن کاملBeating the jetting regime
We study numerically the dynamics of jets and drops in a microcapillary coflow device. The co-flow stream encounters different flow regimes, including dripping, jetting. Using a level-set/finite element axysimmetric numerical simulation, we study the dynamics of breakup of a jet subject to flow rate perturbations. A scaling law for the width of the unperturbed jet is presented and compared to e...
