Background: One-third of American adults encompassed by current colorectal cancer screening guidelines fail to obtain recommended screening evaluations. Educational videos are a valuable medium through which to educate and encourage recommended health behaviors in patients.
Methods: A cross-sectional study reviewing the quality of patient education videos addressing colorectal cancer screening.
Eyelid Spontaneous Blink Analysis and Age-Related Changes Through High-Speed Imaging.
Ophthalmic Plast Reconstr Surg
January 2020
Purpose: To analyze the spontaneous eyelid blink and sphincter closure activity of the orbicularis oculi by measuring the horizontal eyelid movement.
Methods: Individuals 18+ years of age, any ethnicity, and gender were recruited. Participants completed a questionnaire to determine eligibility.
Context: Since 2013, prothrombin complex concentrate (PCCs) have been approved in the United States for the reversal of anticoagulation induced by vitamin K antagonists. However, there has been limited investigation into their use in trauma and acute-care surgery (ACS).
Objective: To investigate the role that 4-factor PCC may have in reversing anticoagulation in the setting of trauma and ACS.
Purpose: To assess the effect of varying levels of torsional power on phacoemulsification efficiency using an active-fluidics phacoemulsification platform with a 0.7 mm Sonata tip.
Setting: John A.
Purpose: To evaluate the effect of vacuum and aspiration rates on phacoemulsification efficiency and chatter using a monitored forced infusion system.
Design: In vitro animal study.
Setting: John A.
Purpose: To optimize phacoemulsification efficiency by varying the intraocular pressure (IOP) using the Centurion Vision System, a monitored forced-infusion system.
Setting: John A. Moran Eye Center Laboratories, University of Utah, Salt Lake City, Utah, USA.
Purpose: To compare the relative efficiency and chatter of the 30-degree 0.9 mm Kelman tip (standard tip) and Ozil Intrepid Balanced tip (torsional tip) with identical optimum settings.
Setting: John A.
Torsional power study using CENTURION phacoemulsification technology.
Clin Exp Ophthalmol
November 2016
Background: To evaluate the effect of varying levels of power on phacoemulsification efficiency using the CENTURION Vision System.
Methods: Formalin-soaked porcine lenses were divided into 2-mm cubes; 0.9-mm, balanced tips were used.
Objective: The aim of this study was to evaluate bent and straight phacoemulsification tips to determine which tip is more efficient in removal of lens fragments, using micropulsed longitudinal ultrasound in phacoemulsification.
Design: In vitro laboratory study.
Methods: The John A.
Purpose: To determine the optimum power settings in micropulsed ultrasound (US).
Setting: John A. Moran Eye Center Laboratories, University of Utah, Salt Lake City, Utah, USA.
Determining optimal ultrasound off time with micropulse longitudinal phacoemulsification.

Purpose: To evaluate the optimum off time for the most efficient removal of lens fragments using micropulse ultrasound (US).
Setting: John A. Moran Eye Center Laboratories, University of Utah, Salt Lake City, Utah, USA.
Purpose: To evaluate the optimum on time for the most efficient removal of lens fragments using micropulsed ultrasound (US).
Setting: John A. Moran Eye Center Laboratories, University of Utah, Salt Lake City, Utah, USA.
A nanomechanical technique for rapid real time detection and monitoring of microorganism growth will significantly reduce costs and diagnosis times in industrial and clinical settings. Owing to their label free detection mechanism and unprecedented sensitivity to the mass and elastic modulus of biological structures, dynamically operated cantilever arrays provide an opportunity to rapidly detect and track the evolution of microbial growth. Here we report the monitoring of the growth of single Aspergillus niger spores via the multimode response of microcantilevers.

Setting: John A. Moran Eye Center Laboratories, University of Utah, Salt Lake City, Utah, USA.
Purpose: To evaluate 3 phacoemulsification tips of different sizes and determine which size is most efficient in lens fragment removal using 3 ultrasound (US) approaches.
Setting: John A. Moran Eye Center Laboratories, University of Utah, Salt Lake City, Utah, USA.
Purpose: To validate a porcine lens model by comparing density and ultrasound (US) with known human standards using the Infiniti Ozil with Intelligent Phacoemulsification (torsional), Whitestar Signature Micropulse (longitudinal), and Ellips FX (transversal) modalities.
Setting: Department of Ophthalmology and Visual Sciences, John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA.
Purpose: To compare efficiency and chatter of Infiniti Ozil with and without Intelligent Phacoemulsification (IP) and the Signature Ellips with and without FX.
Setting: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA.
Biological self-assembled structures are receiving increasing focus within micro- and nanotechnology, for example, as sensing devices, due to the fact that they are cheap to produce and easy to functionalize. Therefore, methods for the characterization of these structures are much needed. In this paper, electrostatic force microscopy (EFM) was used to distinguish between hollow nanotubes formed by self-assembly by a simple aromatic dipeptide, L-phenylalanine, silver-filled peptide-based nanotubes, and silver wires placed on prefabricated SiO2 surfaces with a backgate.
