Beyond single cells: Ten years of commercial lattice light‐sheet microscopy

Journal of Microscopy, EarlyView.
Abstract Lattice light‐sheet microscopy (LLSM) enables gentle, rapid, volumetric fluorescence imaging of living biological systems. The technique employs Bessel beam interference to produce a light‐sheet which retains its thickness over a relatively large field‐of‐view compared to other light‐sheets.

A Microprocessor Based-Instrument for Reconstructing a Coherent Optical Wavefront

, 1977
Characterizing a propagating laser\u27s wavefront is a necessary procedure when evaluating the performance of coherent lasing systems. Measurement of this wavefront structure uncovers more useful information on the operation of lasing systems than does ...

Virtual articulation using sequential mandibular intraoral scans and computational functional rotation reference determination—Proof‐of‐concept

Journal of Prosthodontics, EarlyView.
Abstract Virtual articulators require accurate spatial orientation of digital casts for meaningful occlusal analysis during prosthesis design. Current methods for establishing this orientation rely on facial scanning, cone‐beam computed tomography, electronic jaw tracking, or arbitrary population–based values. This proof‐of‐concept technique presents a

A Stepwise ECG Algorithm to Resolve Identical Precordial Transition in Idiopathic Outflow Tract Ventricular Arrhythmias

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Accurate pre‐procedural differentiation of right (RVOT) versus left ventricular outflow tract (LVOT) origin in idiopathic outflow tract ventricular arrhythmias may facilitate procedural planning and mapping strategy. However, existing 12‐lead ECG criteria show variable performance and often fail to provide clear discrimination when ...

The theoretical basis of reservoir pressure in arteries

Experimental Physiology, EarlyView.
Abstract The separation of measured arterial pressure into a reservoir pressure and an excess pressure was introduced over 20 years ago as a heuristic hypothesis. Since then it has gained some traction through epidemiological studies that show that various measures of reservoir and excess pressure are independent risk factors for cardiovascular disease.

Restitution properties during ventricular fibrillation and the effects of cardiac pacing location on ventricular electrophysiology in the rabbit heart

Experimental Physiology, EarlyView.
Abstract Sudden cardiac death is a cause of mortality due to malignant arrhythmias such as ventricular fibrillation (VF). Although action potential duration (APD) restitution is a method to assess arrhythmic susceptibility, repolarisation may depend on prior activation history, a phenomenon known as cardiac memory.
