Night time eating is a risk factor for metabolic syndrome and obesity. The aim of this study was to investigate whether dinner immediately before bed, snacks after dinner, or combinations of both were associated with metabolic syndrome and its components in a large Japanese cohort. We enrolled 8153 adults aged 40–54 years who participated in specific medical checkups in an Okayama facility from 2009 to 2010 and from 2013 to 2014. Age-adjusted and multivariable-adjusted odds ratios of metabolic syndrome and its components in participants with both night eating habits for an average of 3.9 years were evaluated. The relative excess risk due to interaction (RERI) was utilized to determine the supra-additive interaction of both eating habits on metabolic syndrome and its components. The multivariable-adjusted odds ratio for obesity for those with both eating habits compared to those with neither habit was 2.11 (95% confidence interval [CI], 1.42–3.15) for men and 3.02 (95%CI, 1.72–5.29) for women. Both habits had a supra-additive interaction effect on obesity development in women (RERI, 1.67; RERI%, 85.0; p = 0.058), although this result was not significant. In women, there was an association between eating habits at night and metabolic syndrome, but in men it was unrelated. Both night eating habits were associated with dyslipidemia in men and women. These findings suggest the need for intervention and awareness among individuals with night eating habits to mitigate further complications.

AmyR is a transcriptional activator in Aspergillus spp. necessary for induction of the amylolytic enzyme genes. It recognizes 5'-CGGN8CGG-3' conserved in a number of the amylolytic gene promoters, and in addition 5'-CGGAAATTTAA-3' in the A. oryzae alpha-amylase promoter. In this report, interaction of AmyR with the 5'-CGGAAATTTAA-3' type binding site in the Taka-amylase gene (taaG2) promoter was precisely characterized by DNase I footprinting analysis and electrophoretic mobility shift assay in vitro, and also by examination of the in vivo activity of the mutated promoters. The in vitro and in vivo analyses indicated that two AmyR molecules bind cooperatively to the 5'-CGGAAATTTAA-3' sequence by recognizing the CGG triplet at the 5'-end and the AGG triplet just downstream of the sequence.

Southwestern Japan suffered its worst rains in 2018 causing floods and mudslides, claiming 225 lives and forcing millions for evacuations. Referred as “Heisei san-jū-nenshichi-gatsugōu”, the disaster was the result of incessant precipitation caused by the interaction of typhoon “Prapiroon” with the seasonal rain front "Baiu". The present epidemiological study aims to investigate disaster-induced health issues in 728 residents of Innoshima island in the Hiroshima Prefecture by comparing their clinical data in pre-disaster (2017) and disaster-hit (2018) years which was obtained from annual health screening. Comparison of data showed a significant increase in the urine protein concentration in victims following the disaster. Probing further into the household conditions, showed that a total of 59,844 households were affected with water outage during the heavy rains, which was accompanied by severe damage of sewerage pipelines with complete recovery process taking two weeks. This two weeks of the crisis forced victims to refrain from using restrooms which in turn led to infrequent urination, thereby explaining the increased urine protein concentration in victims following the disaster. The present study addresses the acute health implications caused by the water crisis and serves as a precautionary measure for disaster management council to provide enhanced aftercare services in victims in further events of natural disasters.

• PRRX1 is a poor-prognosis marker of human osteosarcoma. • PRRX1 promotes proliferation, invasion, and drug resistance in human osteosarcoma. • Forskolin was identified using RNA expression signatures of PRRX1 knockdown. • Forskolin decreased proliferation and migration in human osteosarcoma.

Significant achievements in paediatric cardiology, surgical treatment and intensive care of congenital heart disease have drastically changed clinical outcomes for paediatric patients. Nevertheless, late-onset heart failure in children after staged surgeries still remains a serious concern in the medical community. Heart transplantation is an option for treatment; however, the shortage of available organs is a persistent problem in many developed countries. In order to resolve these issues, advanced technologies, such as innovative mechanical circulatory support devices and regenerative therapies, are strongly desired. Accumulated evidence regarding cell-based cardiac regenerative therapies has suggested their safety and efficacy in treating adult heart failure. Given that young children seem to have a higher regenerative capacity than adults, stem cell-based therapies appear a promising treatment option for paediatric heart failure as well. Based on the findings from past trials and studies, we present the potential of various different types of stem cells, ranging from bone marrow mononuclear cells to cardiosphere-derived stem cells for use in paediatric cell-based therapies. Here, we assess both the current challenges associated with cell-based therapies and novel strategies that may be implemented in the future to advance stem cell therapy in the paediatric population.

3-nitrotyrosine (3-NT) is generated from the tyrosine residue in atmospheric bio-aerosol proteins via a reaction with ozone (O₃) and nitrogen dioxide (NO₂). Stable 3-NT is a specific marker for oxidative damage and is reported to have a promotive effect to elicit allergies. In the present study, we report the development of a highly sensitive assay to quantify 3-NT in air sampler filters to collect < 2.5 µm of particulate matter (PM_2.5) from urban environmental air, including bio-aerosol. In this method, a 6 mm-diameter round hole was cut from the filters of air samplers and mixed with a nonspecific protease cocktail in order to hydrolyze proteins. Protein samples digested to the amino acid level were tested for 3-NT using a high-performance liquid chromatography-electrochemical detector (HPLC-ECD). The maximum 3-NT content was detected in a prefilter for PM of sizes from 4.5 to 7.3 μm, with a detection limit of 1.13 pg/m³.
