Reduced Size of Telangiectatic Capillaries After Intravitreal Injection of Anti-Vascular Endothelial Growth Factor Agents in Diabetic Macular Edema.

Purpose: Intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) agents reduces microaneurysms in patients with diabetic macular edema (DME). However, residual anti-VEGF-resistant telangiectatic capillaries (TelCaps) have been reported. In this study, we investigated changes in the size of TelCaps after intravitreal injection of anti-VEGF agents in DME.

Ultra-widefield and anterior-segment optical coherence tomography in Alagille syndrome.

Purpose: We describe the ocular findings in a patient with Alagille syndrome, included those obtained with ultra-widefield and anterior-segment optical coherence tomography (AS-OCT) imaging.

Observations: A previously asymptomatic 29-year-old woman with a heterozygous pathogenic variant in the gene was referred for an ophthalmic evaluation. The ocular abnormalities included bilateral posterior embryotoxon, iris atrophy, retinal pigmentary changes in the peripheral and peripapillary regions, and optic disc elevation.

Visual Outcomes and Prognostic Factors of Large Submacular Hemorrhages Secondary to Polypoidal Choroidal Vasculopathy.

Purpose: Patients with polypoidal choroidal vasculopathy (PCV) may develop large submacular hemorrhages (SMHs), which may result in severe visual loss. This study was performed to determine the visual outcomes and prognostic factors of large SMHs secondary to PCV.

Patients And Methods: We retrospectively reviewed the medical records of patients diagnosed with PCV who developed a large SMH.

Coronary artery lumen complexity as a new marker for refractory symptoms in patients with vasospastic angina.

Refractory angina is an independent predictor of adverse events in patients with vasospastic angina (VSA). The aim of this study was to investigate the relationship between coronary lumen complexity and refractory symptoms in patients with VSA. Seventeen patients with VSA underwent optical coherence tomography.

In Vitro Culture of Single Bovine Embryos with Microwell Plates Made of Poly(dimethylsiloxane) Cured under Low Pressure.

Single embryo culture is useful for assessing the developmental competence of an embryo in detail. Recently, a device made of poly(dimethylsiloxane) (PDMS), which is biocompatible and nontoxic, has been widely used for culture various types of cells. However, PDMS plates are porous, causing the serious osmolality increment of the medium (over 600 mOsm/kg from Day 4 to Day 7).

Selection of high-potential embryos by culture in poly(dimethylsiloxane) microwells and time-lapse imaging.

Objective: To assess the developmental kinetics of human embryos and their ability to develop to morphologically normal blastocysts.

Design: Experimental study on human embryos donated for research using a time-lapse imaging system based on individual embryo culture in poly(dimethylsiloxane) microwells and monitored using a microscope inside the incubator.

Setting: Private fertility clinic.

Individually programmable cell stretching microwell arrays actuated by a Braille display.

Cell culture systems are often static and are therefore nonphysiological. In vivo, many cells are exposed to dynamic surroundings that stimulate cellular responses in a process known as mechanotransduction. To recreate this environment, stretchable cell culture substrate systems have been developed, however, these systems are limited by being macroscopic and low throughput.

Fine surface structure of bovine acrosome-intact and reacted spermatozoa observed by atomic force microscopy.

The atomic force microscope (AFM) provides nanometer resolution, topographic data of the natural surface structure of materials. We studied the topology of the surface structure of bovine sperm heads during the acrosome reaction by AFM. In addition, we numerically analyzed the areas of the median sagittal plane of the sperm heads.
