Purpose: To identify optical coherence tomography (OCT)-based imaging biomarkers that can localize focal leakage points without fluorescein angiography in central serous chorioretinopathy (CSC).
Methods: This retrospective case-control study analyzed 119 consecutive patients (123 eyes) with CSC between April 2018 and February 2024, comprising 66 eyes with focal-leakage type and 57 eyes with diffuse-leakage type. We assessed leakage sites using OCT, and the proportions of OCT findings were compared between focal- and diffuse-leakage types.

Purpose: To comprehensively evaluate baseline characteristics of patients with central serous chorioretinopathy (CSC) and develop predictive risk scores to identify visual prognosis.
Methods: This single-institute, retrospective cohort study included 144 eyes of 144 patients with CSC who underwent photodynamic therapy and achieved serous retinal detachment resolution. We developed and assessed the performance of several risk scores for best-corrected visual acuity (BCVA) outcomes six months post-treatment: i) BCVA improvement (≤-1.
This study aimed to characterize the detailed multi-modal imaging findings of red blood cell (RBC)-coated intraocular lenses (IOLs). A 68-year-old patient with polypoidal choroidal vasculopathy underwent vitrectomy for subretinal and vitreous hemorrhage. Subsequently, RBC-coated IOL was diagnosed.

The study included participants with normal eyes in whom wide-angle OCT images were acquired to generate planarized choroidal en-face and thickness map images. The images were segmented into central, midperipheral, and peripheral areas, and the midperipheral and peripheral areas were further segmented into supratemporal, infratemporal, supranasal, and infranasal sectors.

Therefore, we evaluated the management of HIS-related errors using the proposed human, organization, process, and technology-fit framework to identify the lessons learned. Qualitative case study methodology through observation, interview, and document analysis was conducted at a 1000-bed Japanese specialist teaching hospital.

In this work, an alternating layered structure of [CoFe] complexes and amphiphilic anions was constructed. In the crystal structure, [CoFe] complexes and water molecules formed a hydrogen-bonded supramolecular one-dimensional (1D) chain in the hydrophilic layer.

Background: rhFGF-2 promotes periodontal regeneration, and identifying the factors influencing this regeneration is important for optimizing the effectiveness of rhFGF-2.
Methods And Materials: This study used a hospital information-integrated database to identify patients who underwent periodontal regenerative therapy with rhFGF-2.
Objectives: Krüppel-like factor (KLF)5, which is overexpressed in carcinomas such as oral cancer, inhibits epidermal differentiation. KLF5 induces dedifferentiation of carcinoma cells, which effectuates carcinoma progression; nevertheless, the regulatory mechanism affecting the transcription of the KLF5 gene remains ambiguous.
Methods: Transcriptional activity of the KLF5 silencer, specifically the 425-bp region (425-region), was examined using reporter assays.
Seed-mediated growth has been widely used to synthesize noble metal nanoparticles with controlled size and shape. Although it is becoming possible to directly observe the nucleation process of metal atoms at the single atom level by using transmission electron microscopy (TEM), it is challenging to control the formation and growth of seeds with only a few metal atoms in homogeneous solution systems. This work reports site-selective formation and growth of atomic scale seeds of the Au nanoparticle in a nanospace of an organic cage molecule.

Although there have been numerous reports on delirium in patients with cancer in various conditions, there are no reports that specifically focus on patients with musculoskeletal tumours. This prospective study aimed to investigate the incidence, risk factors and prognostic implications of delirium in patients with musculoskeletal tumours.

Sp3 binding to the minimal essential region (MER) of KLF5 gene is critical for KLF5 basal expression, but the expression control mechanism is unknown.
Objective: This study aimed to identify a regulatory region for KLF5 basal expression and the binding protein in carcinoma cells by analyzing the promoter upstream region.
Purpose: The purpose of this study was to describe a case of polypoidal choroidal vasculopathy, showing a newly developed focal choroidal excavation during a 4-year follow-up period with multiple intravitreal antivascular endothelial growth factor injections.

Combining metal complexes with amphiphilic molecules leads to a wide variety of functional self-assembled nanostructures. Metal complexes exhibiting spin transitions can be good candidates as the trigger to cause structural conversion of such assembly because they respond to various external stimuli. In this work, we studied a structural conversion of a supramolecular assembly containing a [Co Fe ] complex through a thermally induced electron transfer-coupled spin transition (ETCST).

Numerous biomimetic molecular catalysts inspired by methane monooxygenases (MMOs) that utilize iron or copper-oxo species as key intermediates have been developed. However, the catalytic methane oxidation activities of biomimetic molecule-based catalysts are still much lower than those of MMOs. Herein, we report that the close stacking of a μ-nitrido-bridged iron phthalocyanine dimer onto a graphite surface is effective in achieving high catalytic methane oxidation activity.

: When scleral buckling is performed using a #240 encircling band anterior to the equator for rhegmatogenous retinal detachment, buckle migration may occur anteriorly, eroding the rectus muscle. There are few cases of buckle migration occurring simultaneously with buckle infection. Notably, most previous reports included inadequate data on the pathophysiology of buckle migration and did not include the Hess test and perioperative images.

A series of tetranuclear [CuLn] complexes, [CuGd(L)(NO)(HO)](NO)·HO (1), [CuTb(L)(NO)(HO)](NO) (2) and [CuDy(L)(NO)(HO)]·1.5(HO) (3), were synthesized by a one-pot reaction using a simple tetraketone-type ligand (HL = (3,5)-4,5-dihydroxy-3,5-octadiene-2,7-dione). X-ray structural analyses revealed that each complex has a planar tetranuclear core of [CuLn] (Ln = Gd, Tb, and Dy), in which the Ln ion is accommodated in the centre of a CuO metallocycle.
