We compared the effects of concentric (Con) and eccentric (Ecc) isokinetic training on quadriceps muscle strength, cross-sectional area, and neural activation. Women (age 20.0 +/- 0.5 yr) randomly assigned to Con training (CTG; n = 16), Ecc training (ETG; n = 19), and control (CG; n = 19) groups were tested before and after 10 wk of unilateral Con or Ecc knee-extension training. Average torque ...

Eccentric contractions (ECC) require lower systemic oxygen (O2) and induce greater symptoms of muscle damage than concentric contractions (CON); however, it is not known if local muscle oxygenation is lower in ECC than CON during and following exercise. This study compared between ECC and CON for changes in biceps brachii muscle oxygenation [tissue oxygenation index (TOI)] and hemodynamics [tot...

Although the efficacy of extracorporeal circulation (ECC) is well established for open-heart surgery, application of ECC in other surgical areas has not been given much attention. Advances in the related surgical technique and anesthetic management combined with refinements in the ECC procedure itself have encouraged several institutions to use ECC for complex non-cardiac surgeries. ECC is begi...

Xinjiang is in northwest China and has abundant desert sand. Replacing natural sand with from deserts an urgent need could be used making polyethylene fiber−engineered cementitious composite (PE−ECC). The interfacial bonding properties of PE−ECC (DSPE−ECC) were made using the optimal mix proportion (30% content, 2% fiber volume) laboratory’s previous research results. Normal (NSPE−ECC) DSPE-ECC...

Abstract Background Congenital heart disease is a leading cause of death in newborns and infants. The feasibility fetal cardiac surgery linked to extracorporeal circulation (ECC); therefore, cardioplegic solutions need be effective long-lasting. Methods Eighteen pregnant sheep were divided into an ECC-only group, St. Thomas’ Hospital solution (STH1) group (STH group), HTK preservation (Custodio...

In beating cardiomyocytes, synchronized localized Ca2+ transients from thousands of active excitation-contraction coupling sites (ECC couplons) comprising plasma and sarcoplasmic reticulum membrane calcium channels are important determinants of the heart's performance. Nevertheless, our knowledge about the properties of ECC couplons is limited by the lack of appropriate experimental and analysi...

Elliptic Curve Cryptography (ECC) is emerging as an attractive alternative to traditional public-key cryptosystems (RSA, DSA, DH). ECC offers equivalent security with smaller key sizes resulting in faster computations, lower power consumption, as well as memory and bandwidth savings. While these characteristics make ECC especially appealing for mobile devices, they can also alleviate the comput...

Elliptic Curve Cryptography (ECC) is a promising alternative for public-key algorithms in resource-constrained systems because it provides a similar level of security with much shorter keys than conventional integer-based public-key algorithms. ECC over binary field is of special interest because the operations in binary field are thought more space and time efficient. However, the software imp...

Engineered Cementitious Composite (ECC) is a special type of HPFRCC designed using micromechanics concepts which take into account the mechanical interactions between fiber, matrix and interface in deformation processes under load. While the properties of ECC have been extensively investigated, the interaction between ECC and steel reinforcement has not been studied. This interaction is importa...
