Based on the eQTL and meteorological data, we successfully predicted gene expression under environments different from training environments, and in rice cultivars with more complex genotypes than the CSSLs. Our novel approach of eQTL identification facilitated the understanding of the genetic architecture of expression dynamics under field conditions, which is difficult to assess by conventional eQTL studies. The prediction of expression based on eQTLs and environmental information would contribute to the understanding of plant traits under diverse field conditions.

In the Tohoku Medical Megabank Project, we have been developing a series of Japonica Arrays (JPA) for genotyping participants based on reference panels constructed from whole-genome sequence data of the Japanese population. Here, we designed a novel version of the SNP array for the Japanese population, called Japonica Array NEO (JPA NEO), comprising a total of 666,883 markers. Among them, 654,246 tag SNPs of autosomes and X chromosome were selected from an expanded reference panel of 3,552 Japanese, 3.5KJPNv2, using pairwise r2 of linkage disequilibrium measures. Additionally, 28,298 markers were included for the evaluation of previously identified disease risk markers from the literature and databases, and those present in the Japanese population were extracted using the reference panel. Through genotyping 286 Japanese samples, we found that the imputation quality r2 and INFO score in the minor allele frequency bin >2.5-5% were >0.9 and >0.8, respectively, and >12 million markers were imputed with an INFO score >0.8. From these results, JPA NEO is a promising tool for genotyping the Japanese population with genome-wide coverage, contributing to the development of genetic risk scores.

Sickle cell disease (SCD) is a group of inherited blood disorders. The central feature of this chronic condition is pain. Several identified risk factors exacerbate the impact of pain on quality of life (QOL) in SCD; however, there are relatively fewer investigations of strengths-based resilience variables that might buffer the influence of pain on living with SCD. The purpose of this study was to examine strength-based resilience processes in youth with SCD and their parents. Grounded in an ecological resilience-risk model, we evaluated whether adolescent and parent protective factors (pain acceptance, mindfulness, and psychological flexibility) moderated the relation between adolescent-reported pain burden and QOL.

Ninety-three 12- to 18-year-old adolescents with SCD and their parents participated. Adolescents completed assessments of pain characteristics, pain acceptance, mindfulness, and QOL. Parents completed instruments measuring demographic and disease variables and parent psychological flexibilityents living with SCD pain.Pediatric low-grade gliomas (pLGGs) are the most common brain tumor in children, and are associated with life-long clinical morbidity. Relative to their high-grade adult counterparts or other malignant childhood brain tumors, there is a paucity of authenticated preclinical models for these pediatric low-grade gliomas and an incomplete understanding of their molecular and cellular pathogenesis. SRT2104 ic50 While large scale genomic profiling efforts have identified the majority of pathogenic driver mutations, which converge on the MAPK/ERK signaling pathway, it is now appreciated that these events may not be sufficient by themselves for gliomagenesis and clinical progression. In light of the recent World Health Organization reclassification of pLGGs, and pilocytic astrocytoma (PA) in particular, we review our current understanding of these pediatric brain tumors, provide a conceptual framework for future mechanistic studies, and outline the challenges and pressing needs for the pLGG clinical and research communities.Short-term in vitro genotoxicity assays are useful tools to assess whether new and emerging tobacco products potentially have reduced toxicity. We previously demonstrated that potency ranking by benchmark dose (BMD) analysis quantitatively identifies differences among several known carcinogens and toxic chemicals representing different chemical classes found in cigarette smoke. In this study, six whole smoke solution (WSS) samples containing both the particulate and gas phases of tobacco smoke were generated from two commercial cigarette brands under different smoking-machine regimens. Sixty test cigarettes of each brand were machine-smoked according to the International Organization for Standardization (ISO) puffing protocol. In addition, either 60 or 20 test cigarettes of each brand were machine-smoked with the Canadian Intense (CI) puffing protocol. All six WSSs were evaluated in the bacterial reverse mutation (Ames) test using Salmonella typhimurium strains, in the presence or absence of S9 metabolic activation. The resulting S9-mediated mutagenic concentration-responses for the four WSSs from 60 cigarettes were then compared using BMD modeling analysis and the mutagenic potency expressed as number of revertants per μl of the WSS. The quantitative approaches resulted in a similar rank order of mutagenic potency for the Ames test in both TA98 and TA100. Under the conditions of this study, these results indicate that quantitative analysis of the Ames test data can discriminate between the mutagenic potencies of WSSs on the basis of smoking-machine regimen (ISO vs. CI), and cigarette product (differences in smoke chemistry).Inflammatory bowel diseases (IBDs), including Crohn’s disease and ulcerative colitis predispose patients to malnutrition due to a combination of increased basal metabolic rate, decreased oral intake, and increased nutritional losses and malabsorption. Malnutrition is common, affecting up to 75% of patients with Crohn’s disease and 62% of patients with ulcerative colitis, and is associated with worse disease prognosis, higher complication rates, decreased quality of life, and increased mortality risk. It is imperative to screen patients with IBD for malnutrition to assess those at increased risk and treat accordingly to prevent progression and complications. This literature review provides an overall approach to optimizing nutrition in IBD, focusing on the assessment for the diagnosis of malnutrition, management of macro- and micronutrient deficiencies, and identification of areas for future study.
