Efficacy and Safety of the Sync-AV II Temporary Cardiac Pacing Catheter (EASY II Trial)
Cardiac pacing is crucial for patients with hemodynamically unstable bradyarrhythmias. For most indications, transvenous pacemakers are used to pace the right ventricle, causing atrioventricular dyssynchrony, which may lead to significant hemodynamic ...

Use of an audio-paced incremental swimming test in young national-level swimmers [PDF]
, 2008 PURPOSE: To evaluate the reliability and sensitivity to training of an audio-paced incremental swimming test.METHODS: Eight young national-level male swimmers (age 15 +/- 1 year) performed a 7 x 200-m incremental swimming test (velocities 1.19, 1.24, 1 ...

Quality-of-life in DDDR pacing: Atrioventricular synchrony or rate adaptation?
, 1994 Although differences in exercise performance have been observed between different rate adaptive modes, the relative impact of atrioventricular (AV) synchrony and rate adaptation on quality of life (QOL) have not been determined.

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State
American Journal of Botany, EarlyView.Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

American Journal of Botany, EarlyView.Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Annals of Neurology, EarlyView.Gut wall physiology in multiple sclerosis (MS) and autoimmune neurologic diseases remains underexplored but may span gut barrier dysfunction, enteric glial targeting, mucosal immune dysregulation, and autoimmune targets within the enteric nervous system (ENS).

Advanced NanoBiomed Research, EarlyView.Electrical stimulation of human pluripotent stem cell‐derived cardiomyocytes is systematically investigated as a function of electrode material and configuration. Stimulation efficiency is found to be governed predominantly by electrode geometry, with increased electrode area and proximity to cells enabling more effective pacing.

The Anatomical Record, EarlyView.Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

The Anatomical Record, EarlyView.Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...
