Epicardial placement of human placental membrane allografts in coronary artery bypass graft surgery is associated with reduced postoperative atrial fibrillation: a pilot study for a future multi-center randomized controlled trial

Journal of Cardiothoracic Surgery
Background Post-operative atrial fibrillation (POAF) occurs in up to 40% of patients following coronary artery bypass grafting (CABG) and is associated with a higher risk of stroke and mortality.

Fast MTF measurement of CMOS imagers at the chip level using ISO 12233 slanted-edge methodology [PDF]

, 2004
MTF measurement methods for imaging devices usually require the use of an optical system to project the image of the object onto the detector. So, MTF results quality strongly depends on the accuracy of the optical adjustments (alignments, focusing ...

Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

Advanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.

Tissue Augmentation with Allograft Adipose Matrix For the Diabetic Foot in Remission

Plastic and Reconstructive Surgery, Global Open, 2017
Background:. Repetitive stress on the neuropathic plantar foot is the primary cause of diabetic foot ulcers. After healing, recurrence is common. Modulating plantar pressure has been associated with extension of ulcer free days.

Fast MTF measurement of CMOS imagers using ISO 12233 slanted-edge methodology [PDF]

, 2004
The ISO 12233 standard provides a fast and efficient way of measuring Modulation Transfer Function (MTF) of digital input devices (such a digital still camera) using a normalized reflective target based on a slanted-edge method. A similar methodology has

Creating effective focus cues in multi-plane 3D displays. [PDF]

, 2011
Focus cues are incorrect in conventional stereoscopic displays. This causes a dissociation of vergence and accommodation, which leads to visual fatigue and perceptual distortions.

Collinear, two-color optical Kerr effect shutter for ultrafast time-resolved imaging [PDF]

, 2014
Imaging with ultrashort exposure times is generally achieved with a crossed-beam geometry. In the usual arrangement, an off-axis gating pulse induces birefringence in a medium exhibiting a strong Kerr response (commonly carbon disulfide) which is ...
