Global myocardial ischemia and ischemia-reperfusion injury are potential adverse events related with cardioplegic arrest. Beating heart surgery has avoided such complications and adapted to valve surgery following successful results published on myocardial revascularization. Difficulty in weaning from cardiopulmonary bypass may be lessened by using on-pump beating heart surgery for mitral valve...

We examine the hydrodynamic performance of two cilia beating patterns reconstructed from experimental data. In their respective natural systems, the two beating patterns correspond to: (A) pumping-specialized cilia, and (B) swimming-specialized cilia. We compare the performance of these two cilia beating patterns as a function of the metachronal coordination in the context of two model systems:...

OBJECTIVE To investigate the factors associated with attitudes towards wife beating among women in partnerships in Zimbabwe in order to assist public health practitioners in preventing intimate partner violence (IPV). METHODS A nationally representative survey of 5907 women of reproductive age (15-49 years) was conducted in Zimbabwe. Women were asked about their attitudes towards wife beating...

This paper investigates the use of Kinect depth sensors as well as inertial sensors in the context of beating heart surgery. In the past, various sensors have been used in attempts to track the beating heart, each with its own distinct set of advantages and disadvantages. With the availability of affordable structured-light depth sensors such as the Kinect and sufficiently small and low priced ...

Webster, Daniel R., and Darby L. Patrick. Beating rate of isolated neonatal cardiomyocytes is regulated by the stable microtubule subset. Am J Physiol Heart Circ Physiol 278: H1653–H1661, 2000.—We investigated the roles of microtubule (MT) dynamics (growth and shrinkage), the stable, nongrowing MT subset, the posttranslationally detyrosinated MT subset, and artificially elevated tubulin levels ...

In order to elucidate the biochemical mechanism by which doxorubicin (DX) induces cumulative dose-dependent cardiomyopathy, the effect of DX on beating and on lipid peroxide level in myocardial cells was investigated by using a mouse myocardial cell culture system. Inhibition by DX of the beating of cultured myocardial cells was doseand exposure timedependent. When incubated with DX for 0.5 h, ...

In response to light stimulation Chlamydomonas reinhardtii changes the beating frequency, beating pattern, and beating synchrony of the trans and cis cilia to steer the freely-swimming cell relative to light sources. To understand the cell steering behavior the impulse responses of the beating frequency and stroke velocity of each cilium have been obtained with high temporal resolution on cells...

We have developed a simple protocol for inducing the myocardial differentiation of human induced pluripotent stem (iPS) cells. Human iPS cell-derived embryonic bodies (EBs) were treated with a combination of activin-A, bone morphogenetic protein-4 and wnt-3a for one day in serum-free suspension culture, and were subsequently treated with noggin for three days. Thereafter, the EBs were subjected...

Background: The capability of embryonic carcinoma cells P19 in differentiation to Cardiomyocyte was examined through inducing effects of Oxytocin (OT) and 5-Azacytidin (5Az) individually and compared with each other in laboratory condition. Materials and Methods: P19 Embryoid Bodies (EBs) was formed through hanging drops method. Then, EBs were treated with (5Az) or (OT) and the EB medium (Ct...
