Overdrive Suppression
THE RELATIONSHIP among cardiac pacemakers is characterized by the fact that usually one pacemaker is dominant and all the others are subsidiary. The sinoatrial node acts as the dominant pacemaker and all other pacemaker tissues are discharged by a conducted impulse before their diastolic depolarization can attain threshold. These pacemakers are called subsidiary to emphasize the fact that under...
متن کاملPacing-Overdrive Dog
The functional integrity of the (3and a-adrenergic stimulatory pathways in a rapid ventricular pacing model of congestive heart failure in dogs was investigated; normal dogs served as controls. Total (-adrenergic receptor density was 35% lower (p<O.O1) in the pacing-overdrive dogs, and the (-adrenergic receptor-mediated stimulation of adenylate cyclase (Vm.) was found to be 68% and 72% lower (p...
متن کاملOverdrive: Making SPDZ Great Again
SPDZ denotes a multiparty computation scheme in the preprocessing model based on somewhat homomorphic encryption (SHE) in the form of BGV. At CCS ’16, Keller et al. presented MASCOT, a replacement of the preprocessing phase using oblivious transfer instead of SHE, improving by two orders of magnitude on the SPDZ implementation by Damg̊ard et al. (ESORICS ’13). In this work, we show that using SH...
متن کاملShifting RNA polymerase into overdrive.
To direct expression of a gene, RNA polymerase (RNAP) must efficiently transcribe (copy) DNA into an mRNA molecule that is thousands to millions of nucleotides long. Organisms from bacteria to humans regulate gene expression by making RNAPs that readily hesitate, stop, or fall off the DNA template when they encounter certain sequences (called pause, arrest, or termination signals). There also e...
متن کاملself-adapting autodecremental overdrive pacing
The efficacy and safety of a new antitachycardia pacing technique, self-adapting decremental overdrive pacing, was assessed in patients with clinical ventricular tachyarrhythmias who underwent programmed ventricular stimulation and serial drug testing. The three phases of this study involved a learning/experience phase, followed by intrapatient comparison of decremental overdrive pacing with co...
