Association between microenvironment-related genes and prognosis of primary central nervous system lymphoma.

Background: Primary central nervous system lymphoma (PCNSL) is a rare lymphoid malignancy. Systemic profiling of the PCNSL tumor microenvironment (TME) was previously conducted through gene expression analysis. We investigated the prognostic impact of TME on survival to establish novel prognostic biomarkers in PCNSL patients.

Detrimental Effect of Acute Hyperglycemia on the Outcomes of Large Ischemic Region Stroke.

Background: Although endovascular therapy (EVT) is effective for large ischemic region strokes, the impact of hyperglycemia remains unclear.

Methods And Results: We analyzed data from the RESCUE-Japan LIMIT (Recovery by Endovascular Salvage for Cerebral Ultra-Acute Embolism-Japan Large Ischemic Core) trial, which randomized stroke patients with Alberta Stroke Program Early Computed Tomography Score of 3 to 5 to EVT versus medical management. Outcomes were compared among patients with normoglycemia (<140 mg/dL), moderate hyperglycemia (≥140, <180 mg/dL), and severe hyperglycemia (≥180 mg/dL) on admission.

Anti-epileptic drug use and subsequent degenerative dementia occurrence.

Introduction: The use of anti-epileptic drugs (AEDs) in degenerative dementia (DD) remains uncertain. We aimed to evaluate the association of early AED administration with subsequent DD occurrence.

Methods: Using a large nationwide database, we enrolled patients newly diagnosed with epilepsy from 2014 to 2019 ( = 104,225), and using propensity score matching, we divided them into treatment (those prescribed AEDs in 2014) and control groups.

Uncoupling endocardial bundles coupled by an epicardial bundle in the left atrium and pulmonary veins.

Uncoupling of the endocardial bundles in the left atrium was suggested during modified posterior wall isolation. Although this fact may not be observed because of the possible bridging conduction by epicardial bundles in humans, partially failed transmural ablation in the atrial roof may have iatrogenically unveiled this fact.

Development of the trainer skill evaluation scale for metacognitive training.

Aim: The purpose of this study is manifold: to develop a trainer skill rating scale for metacognitive training (MCT), to determine the difficulty level of the behavioral checklist, and to examine the reliability and validity of the MCT Trainer Skills Rating Scale.

Method: In Study 1, an MCT trainer skill behavior checklist was developed with expert staff members, and a questionnaire was administered to MCT trainers. Item categorization was identical to that used in previous studies.

Response of stomatal density and size in to contrasting climate conditions: The contributions of genetic and environmental factors.

As plant distribution and performance are determined by both environmental and genetic factors, clarifying the contribution of these two factors is a key for understanding plant adaptation and predicting their distribution under ongoing global warming. is an ideal species for such research because of its wide distribution across diverse environments. Stomatal density and size are crucial traits that plants undergo changes in to adapt to different environments as these traits directly influence plant photosynthesis and transpiration.

Bone mineral density changes around the stem correlate with stress changes after total hip arthroplasty: A study using thermoelastic stress analysis.

Purpose: Thermoelastic stress analysis (TSA) was used to evaluate stress changes over the entire surface of a specimen. This study aimed to assess the relationship between femoral stress distribution, analysed using TSA and changes in bone mineral density (BMD) after total hip arthroplasty (THA).

Methods: Stress changes in the simulated bone before and after taper-wedge stem insertion were measured using the TSA.

An Alternative Approach to Determining Metabolic Syndrome Component Cutoffs in Children and Adolescents Using Segmental Regression Analysis.

The prevalence of metabolic syndrome is increasing in children and adolescents. Although some diagnostic criteria for metabolic syndrome exist, further research is needed to determine appropriate age-, sex-, and race-specific cutoffs for each component. Health examinations were conducted in 1,679 children aged 6-15 years in 9 regions of Japan.

Perforating collagenosis.

We show a case of a 69-year-old man with perforating collagenosis, which is a rare dermatosis commonly associated with diabetes mellitus. Papules and plaques with keratotic plugs are distinctive clinical characteristic of perforating collagenosis. Representative clinical images in our article can enhance the understanding of key concepts of perforating collagenous.

Detection of evolutionary conserved and accelerated genomic regions related to adaptation to thermal niches in lizards.

Understanding the genetic basis for adapting to thermal environments is important due to serious effects of global warming on ectothermic species. Various genes associated with thermal adaptation in lizards have been identified mainly focusing on changes in gene expression or the detection of positively selected genes using coding regions. Only a few comprehensive genome-wide analyses have included noncoding regions.

Diurnal and geographic variations of pollinator importance for Duchesne.

Despite growing awareness of the importance of monitoring wild crop pollinators worldwide, there are still few reports, especially in East Asia. Considering ongoing global warming may change the distribution range and diurnal activity of pollinators, it is necessary to describe current geographic and diurnal patterns. We clarified pollinators of Duchesne (Cucurbitales: Cucurbitaceae) in three geographically distinct (>350 km, minimum) areas in Japan, focusing on diurnal variation.

Potential Impacts of Energy and Vehicle Transformation Through 2050 on Oxidative Stress-Inducing PM Metals Concentration in Japan.

The impacts of renewable energy shifting, passenger car electrification, and lightweighting through 2050 on the atmospheric concentrations of PM total mass and oxidative stress-inducing metals (PM-Fe, Cu, and Zn) in Japan were evaluated using a regional meteorology-chemistry model. The surface concentrations of PM total mass, Fe, Cu, and Zn in the urban area decreased by 8%, 13%, 18%, and 5%, respectively. Battery electric vehicles (BEVs) have been considered to have no advantage in terms of non-exhaust PM emissions by previous studies.

Diversity and composition of flower-visiting insects and related factors in three fruit tree species.

Animal-mediated pollination is an essential ecosystem service for the production of many fruit trees. To reveal the community composition of flower-visiting wild insects which potentially contribute to fruit production and to examine the effects of geographic location, local meteorological conditions and locally introduced domesticated pollinators on them, we investigated the community composition of insects visiting the flowers (hereafter, "visitors") of apple, Japanese pear and Oriental persimmon for 1‒3 years at 20 sites around Japan. While most of the variation (82%) of the community composition was explained by tree species with a slight contribution by geographic distance (2%), maximum temperature and tree species contributed 62% and 41% of the variation in total abundance of the visitors, respectively.

Onlinization of a simulation course that includes minor emergency procedures.

Aim: We attempted to convert a simulation course held on-site for primary care physicians to learn about the initial treatment of minor emergencies, including some common surgical procedures, to an online format.

Methods: We reviewed the subjects covered in the course and evaluated whether it was "decision-making" or "technical skills" that had been primarily taught as simulation-based training for each subject, and then supplemented the contents accordingly.

Results: As a result, satisfaction levels with the online course were comparable to those with the on-site course as measured by a postcourse questionnaire (97.

Association between family caregivers' primary care experience when they report as patients and their stress related to caregiving: A pilot cross-sectional study.

Background: Few studies have examined whether family caregivers' own primary care providers can affect caregiving-specific well-being, such as caregiver stress. In this pilot study, we explored whether primary care experiences when family caregivers report as patients were associated with the stress of caregiving.

Methods: We used cross-sectional data from a survey conducted in Japan between November and December 2020.

Hospital-Level Variation in Cardiac Rehabilitation After Myocardial Infarction in Japan During Fiscal Years 2014-2015 Using the National Database.
