Purpose: To assess the effects of modifying head position and of static ocular counter-rolling (OCR) on abduction and adduction in saccadic eye movements using a head-mounted video-oculographic device.
Study Design: A clinical observational study.
Methods: The peak velocities and amplitude gains of visually guided 12° saccades were binocularly measured in 21 healthy volunteers with their heads in the upright vertical (0°) and horizontal (± 90°, bilateral side-lying) postures, and in 6 participants with their head positions bilaterally tilted by 30°.
Article Synopsis
- Indano[60]fullerene bromide is an important intermediate in making indano[60]fullerene ketone, a derivative that can easily evaporate.
- Researchers utilized aqueous hydrobromic acid to create a consistent and high-yielding reaction process.
- A method for a scalable one-pot synthesis of indano[60]fullerene ketone from aryl[60]fullerenyl dimers was successfully demonstrated.
Objective This study aims to investigate the risk factors for lymph node metastasis (LNM) and postoperative recurrence in patients undergoing surgery for pT1 colorectal cancer (pT1-CRC). Materials and methods We retrospectively analyzed 150 patients who underwent bowel resection with lymph node dissection for pT1-CRC at our department between September 2011 and December 2021. Univariate and multivariate analyses were performed to examine the effects of sex, depth of tumor invasion, venous invasion, lymphatic invasion, tumor budding (BD), and histological type on LNM and recurrence.

This is the first example of L-glutamate oxidase from a marine microorganism. A chemically synthesized gene optimized for codon usage in E.

To address this issue, we determined the loop length preoperatively using 4-dimensional computed tomography.
Methods: The loop length was determined on the basis of the distance from the papillary muscle head to the free margin of nonprolapsing leaflet corresponding to the prolapsed leaflet, to which the loops would be secured.
