Synchronization and Resynchronization of Ovulation and Timed Insemination in Lactating Dairy Cows and Heifers
… service was 30.5% with ESR of 82.8%. Overall resynchronization PR was 35.1% with an ESR of 84.8%. In conclusion, Ovsynch and CIDR-based protocols are equally effective in synchronizing ovulation in a TAI program and resulted in comparable PR.

Responding to resynchronization : improving the impact of biventricular pacing in the management of chronic heart failure
Cardiac resynchronization therapy (CRT) is a recent therapeutic intervention that is delivered by the implantation of a biventricular pacemaker system. The mechanism of action is believed to be the correction of dyssynchrony of myocardial contraction. This approach can reduce morbidity and …

An analysis of defibrillation and cardiac resynchronization therapy strategies in patients with failing systemic right ventricles
The expanding application of cardiac resynchronization (CRT) and implantable cardioverter-defibrillator therapy (lCD) to include patients with congenital heart disease requires careful evaluation of selection criteria and unconventional adaptive strategies to ensure clinical efficacy. A single …

The effects of resynchronization of estrus using the 5 d CO-Synch + CIDR system in beef heifers
… and define economic parameters of a FTAI resynchronization protocol in beef heifers after synchronization using a 5d CO-Synch + CIDR system. Estrus was synchronized in crossbred heifers (n=176) using 5 d CO-Synch + CIDR with FTAI at 72 h. After the initial AI, open heifers received either …

Investigation of over-fitting and optimism in prognostic models
… was a major study into the effects of cardiac resynchronization. Cardiac resynchronization has been shown to reduce mortality in patients suffering heart failure due to electrical problems in the heart. The prognostic model presented in this work was motivated by the question as to which …

Personalized Biomechanical Heart Modeling for Clinical Applications
… to predict the short-term effect of the Cardiac Resynchronization Therapy (CRT) by means of an increase of ‘max LV dp/dt’. The model personalization was performed using patients MRI and pressure data in the baseline condition — prior to CRT. Then we fixed the values of all parameters and applied …
