This retrospective observational multicentre cohort study compared the rate of postoperative cystoid macular oedema (CME) between two intraocular lens (IOL) scleral fixation (SFIOL) techniques: a flanged IOL fixation technique (Yamane technique) and a suture IOL transscleral fixation technique (conventional technique). The study included 207 eyes with postoperative CME that had undergone SFIOL and were observed for > 12 weeks between January 2019 and January 2021. The primary endpoint was a comparison of the rate of postoperative CME at 3 months between groups.

In addition to conventional hybridoma-based screening, recombinant antibody-based screening has become a common choice; however, its application is hampered by two factors: (1) screening starts after Ig gene cloning and recombinant antibody production only, and (2) the antibody is composed of paired chains, heavy and light, commonly expressed by two independent expression vectors. Here, we introduce a method for the rapid screening of recombinant monoclonal antibodies by establishing a Golden Gate-based dual-expression vector and in-vivo expression of membrane-bound antibodies.

Tiptoe standing requires a high and stable foot arch structure, which is achieved by contraction of the plantar intrinsic foot muscles (PIFMs). Long-term repetitive loading with a specific movement can induce hypertrophic adaptation of the associated muscles.

Methods: A total of 184 diabetic eyes were analyzed. UWF-CF and UWF-FA images were graded based on the International Clinical Diabetic Retinopathy severity scale.
The activity of occipitotemporal regions involved in linguistic reading processes, such as the ventral occipitotemporal cortex (vOT), is believed to exhibit strong interactions during higher-order language processing, specifically in the connectivity between the occipital gyrus and the temporal gyrus. In this study, we utilized functional magnetic resonance imaging (fMRI) with psychophysiological interaction (PPI) and dynamic causal modeling (DCM) to investigate the functional and effective connectivity in the occipitotemporal network during speed reading. We conducted the experiment with native Japanese speakers who underwent and without speed-reading training and subsequently performed established reading tasks at different speeds (slow, medium, and fast) while undergoing 3-Tesla Siemens fMRI.

We evaluated the efficacy, immunogenicity, and safety of S-268019-b, a recombinant spike protein subunit vaccine based on the ancestral strain, for preventing symptomatic coronavirus disease 2019 (COVID-19) during the Omicron (BA.2)-dominant period in Vietnam.

Here, we hypothesized that MLC density was correlated with ischemia using optical coherence tomography angiography (OCTA) and ultra-widefield fluorescein angiography (UWF-FA). Treatment-naïve diabetic eyes were prospectively imaged with repeated OCTA (average 5.

Patients And Methods: We performed 226 KM-CART procedures in 104 patients with malignant ascites in three hospitals from August 2013 to September 2018. Medical records were retrospectively reviewed for ascites data, related complications, symptoms before and after each CART and prognosis after the first CART.

Background: Minimizing postural sway during tiptoe standing is essential for ballet dancers. Investigation of the activity of the plantar intrinsic foot muscles (PIFMs) may provide insight into postural sway in dancers. Herein, we compared PIFM activity during tiptoe standing between dancers and non-dancers and examined its relationship with postural sway.

Cilostazol, a selective type 3 phosphodiesterase inhibitor, promotes such clearance by facilitating intramural periarterial drainage.
Objective: To determine the safety and efficacy of cilostazol in mild cognitive impairment.

Purpose: The purpose of this study was to investigate and compare the corresponding alterations of the pupillary response between acute and chronic central serous chorioretinopathy (CSC) and between different disease categories.
Methods: We recruited patients with unilateral acute and chronic CSC. An eye tracker was applied to determine the pupillary light reflex (PLR) and evaluate the following PLR metrics in healthy eyes: pupil diameter, diameter changes, including relative constriction amplitude (AMP%), and re-dilation ratio (D1%).
Purpose: To evaluate the influence of tamponade on the visual and anatomic outcomes of pars plana vitrectomy for myopic traction maculopathy (MTM).
Design: Multicenter, retrospective clinical cohort study.
Methods: Consecutive eyes that underwent vitrectomy for advanced MTM with tamponade of air, sulfur hexafluoride (SF), or perfluoropropane (CF) or without tamponade with a minimum follow-up of 12 months were included.
Objective: To evaluate the correlation between nonperfusion parameters on OCT angiography (OCTA) and ultrawide-field fluorescein angiography (UWF-FA) in subjects with diabetes mellitus (DM).
Design: Prospective, cross-sectional study.
Subjects: Subjects with DM and a wide range of diabetic retinopathy (DR) severity seen at a tertiary referral center.

Purpose: This study assessed the autonomic nervous system in patients with central serous chorioretinopathy (CSC) by simultaneously measuring pupillary responses and heart rate variability (HRV).
Methods: We recruited 33 patients with CSC and 26 age- and sex-matched healthy controls. Using a pupillometry and acceleration plethysmography system, we measured the participants' pupillary light reflex and HRV simultaneously, and compared the following parameters between the two groups: the pupil diameters, diameter changes, and time and frequency domain HRV indices (high frequency power: HF; low frequency power: LF; log LF/HF ratio).
