Intravascular large B-cell lymphoma with respiratory failure diagnosed by random skin biopsy: A case report.

Intravascular large B-cell lymphoma (IVLBCL) typically involves nonspecific symptoms that complicate diagnosis. This report discusses the case of a 70-year-old man, who presented with dyspnea, fatigue, and weight loss that evolved into severe respiratory failure, diagnosed with IVLBCL via random skin biopsy. The initial improvement in respiratory symptoms was followed by coronavirus disease.

A retrospective cohort study evaluating the incidence of herpes zoster and postherpetic neuralgia after a live attenuated Oka-strain herpes zoster vaccine in a real-world setting in Japan.

Background: In Japan, freeze-dried live attenuated Oka-strain varicella-zoster virus vaccine, VVL (BIKEN), is available for adults aged ≥50 years to prevent herpes zoster (HZ). Although an increase in the antibody titer and cellular immune response has been demonstrated following vaccination with VVL (BIKEN), to date, no clinical studies have shown that the vaccine decreases the incidence of HZ and postherpetic neuralgia (PHN). This study investigated the incidence of HZ and PHN among adults aged ≥50 years who received a single dose of VVL (BIKEN) to prevent HZ.

Effect of differences in light source environment on transcriptome of leaf lettuce (Lactuca sativa L.) to optimize cultivation conditions.

When used in closed-type plant factories, light-emitting diode (LED) illumination systems have the particular advantages of low heat emission and high luminous efficiency. The effects of illumination quality and intensity on the growth and morphogenesis of many plant species have been examined, but improvements are needed to optimize the illumination systems for better plant products with lower resource investments. In particular, new strategies are needed to reduce the wastage of plant products related to leaf senescence, and to better control the ingredients and appearance of leafy vegetables.

A REMOTE CONTINUOUS AIR MONITORING SYSTEM FOR MEASURING AIRBORNE ALPHA CONTAMINATION.

We developed a remote continuous air monitoring (RCAM) system. The RCAM system consisted of a personal air monitor and a robot. The personal air monitor (poCAMon, SARAD, Germany) had a 400-mm2 ion-injected silicon detector and a membrane air filter with 25 mmφ.

In vitro investigation of fracture load and aging resistance of high-speed sintered monolithic tooth-borne zirconia crowns.

Objectives: The purpose of this study was to evaluate the fit, fracture load and aging resistance of the monolithic zirconia tooth-borne crowns with conventional and high-speed sintering.

Methods: The Y-TZP block was machined and sintered with conventional and high-speed sintering furnace. The marginal and internal gap between the crown and abutment was measured using a microscope and a fit checking material.
