DNA methylation and expression of MAPRE3 affect overall survival of early‐stage non‐small cell lung cancer patients

Molecular Oncology, EarlyView.
Both cg12821679MAPRE3 methylation and MAPRE3 expression are significantly associated with overall survival (OS) of non‐small cell lung cancer. Meanwhile, MAPRE3 expression significantly modified the effect of smoking cessation on OS. Smoking cessation benefits OS merely for patients with high MAPRE3 expression.

In vivo identification of angle dysgenesis and its relation to genetic markers associated with glaucoma using artificial intelligence

Indian Journal of Ophthalmology
Purpose: To predict the presence of angle dysgenesis on anterior-segment optical coherence tomography (ADoA) by using deep learning (DL) and to correlate ADoA with mutations in known glaucoma genes.

Volumetric microvascular imaging of human retina using optical coherence tomography with a novel motion contrast technique [PDF]

, 2009
Phase variance-based motion contrast imaging is demonstrated using a spectral domain optical coherence tomography system for the in vivo human retina. This contrast technique spatially identifies locations of motion within the retina primarily associated

Circulating tumor cell viability during and after radiotherapy mirrors treatment response in cancer patients

Molecular Oncology, EarlyView.
Radiotherapy (RT) response depends on the DNA repair capacity of tumor and host cells. We show that circulating tumor cell (CTC) counts and apoptosis rates before and after RT predict treatment response and outcome, which can be accessed via easily accessible liquid biopsy approaches. Created in BioRender. Wikman, H.

Wound morphologies of sclerotomies closed with scleral massage and scleral needling techniques: A comparative study

Indian Journal of Ophthalmology
Background: This prospective study aimed to compare scleral needling with the conventional scleral massage technique for sclerotomy closure, using anterior segment optical coherence tomography (AS-OCT) to assess postoperative wound morphology.

Design and implementation of a low-cost, portable OCT system.

Biomedical Optics Express, 2018
Optical coherence tomography (OCT) is a widely used biomedical imaging tool, primarily in ophthalmology to diagnose and stage retinal diseases. In order to increase access for a wider range of applications and in low resource settings, we developed a ...

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

FEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Assessment of sclerocorneal incision architecture after phacoemulsification using AS-OCT

Scripta Scientifica Medica, 2018
Introduction The construction of the main incision is crucial for the outcome of cataract surgery.  There are many considerations including: wound preparation and stability, surgically induced astigmatism, stability of anterior chamber, and wound closure stability with rising intraocular pressure (IOP).
