Recent research has shown that the molecule c-di-GMP is an important second messenger regulating various functions in bacteria. In particular, the implication of c-di-GMP as a positive regulator of adhesion and biofilm formation has gained momentum as a highly relevant research topic, as detailed knowledge about the underlying regulatory mechanisms may enable the development of measures to control biofilms in both industrial and medical settings. Accordingly, it is in many cases of interest to measure the c-di-GMP level in bacteria under specific conditions or in specific mutant strains. We have developed a collection of fluorescence-based c-di-GMP biosensors capable of gauging the c-di-GMP level in Pseudomonas aeruginosa and closely related bacteria. Here, we describe protocols for the use of these biosensors in gauging and visualizing cellular c-di-GMP levels of P. aeruginosa both in in vitro setups such as continuous-culture flow-cell biofilms, and in in vivo settings such as a murine corneal infection model.

: In this study, we evaluated the incidence of cystoid macular edema (CME) after pars plana vitrectomy (PPV) for different retinal pathologies and assessed the role of optical coherence tomography (OCT) biomarkers in guiding treatment decisions in post-surgical CME patients who were refractory to medical therapy over a follow-up period of 12 months. : Medical records of consecutive pseudophakic patients, who underwent PPV for different retinal pathologies, were retrospectively evaluated in this single-center, uncontrolled study. The incidence of post-PPV CME was assessed.

Purpose: To compare the efficac and safety of a dual-blade 20,000 cuts per minute (cpm) vitrectomy probe with a single-blade 10,000 cpm probe for primary rhegmatogenous retinal detachment (RRD).
Study Design: Prospective, randomized controlled clinical trial.
Methods: Evaluations were conducted preoperatively, intraoperatively, and at three months postoperatively.

The orientation of a blood vessel as visualized in 3D medical images is an important descriptor of its geometry that can be used for centerline extraction and subsequent segmentation, labeling, and visualization. Blood vessels appear at multiple scales and levels of tortuosity, and determining the exact orientation of a vessel is a challenging problem. Recent works have used 3D convolutional neural networks (CNNs) for this purpose, but CNNs are sensitive to variations in vessel size and orientation.

Purpose: To describe a custom bent 27-gauge needle-guided suture snare technique for scleral fixation of posterior chamber intraocular lenses (PCIOL).
Methods: An 8-0 polypropylene suture was threaded into the lumen of a custom bent 27-gauge needle, and the needle tip was advanced into the eye from the intraocular lens (IOL) fixation point. The suture was threaded through the posterior limbal incision inside the IOL haptic loop and pulled out.
