Clinical and bacteriological characteristics of Corynebacterium keratitis.

Purpose: Corynebacterium species are commensals of human skin and mucous membranes and are recognized as important pathogens in ocular infections. This study investigated the clinical characteristics of Corynebacterium keratitis.

Methods: We retrospectively reviewed cases of bacterial keratitis in which Corynebacterium species were solely isolated from corneal scraping cultures collected at Ehime University Hospital between January 2010 and February 2024.

Interstitial lung disease in a patient with anti-eIF2B antibodies-positive systemic sclerosis: A case report and literature review.

We report the case of a 76-year-old male patient with systemic sclerosis positive for anti-eukaryotic initiation factor 2B (eIF2B) antibodies. He presented to our hospital with dyspnea on exertion and, following a comprehensive physical examination, was diagnosed with interstitial lung disease associated with systemic sclerosis. Furthermore, systemic sclerosis was positive for the anti-eIF2B antibody.

Development of a DualEmission Laser-Induced Fluorescence (DELIF) Method for Long-Term Temperature Measurements.

The fluorescence intensity of fluorescent dyes typically employed in the dual-emission laser-induced fluorescence (DELIF) method gradually degrades as the excitation time increases, and the degradation rate depends on the type of fluorescent dye used. Therefore, the DELIF method is unsuitable for long-term temperature measurements. In this study, we focused on the fluorescence intensity ratio of a single fluorescent dye at two fluorescence wavelengths and developed a DELIF method for long-term temperature measurements based on this ratio.

Cryptic cytoplasmic male sterility-causing gene in the mitochondrial genome of common japonica rice.

Cytoplasmic male sterility (CMS) is an agronomically significant trait that causes dysfunction in pollen and anther development. It is often observed during successive backcrossing between distantly related species. Here, we show that Asian japonica cultivars (Oryza sativa) exhibit CMS when the nucleus is replaced with that of the African rice Oryza glaberrima.
