Combinatorial motif analysis of regulatory gene expression in Mafb deficient macrophages

<p>Abstract</p> <p>Background</p> <p>Deficiency of the transcription factor MafB, which is normally expressed in macrophages, can underlie cellular dysfunction associated with a range of autoimmune diseases and arteriosclerosis. MafB has important roles in cell differentiation and regulation of target gene expression; however, the mechanisms of this regulation and the identities of other transcription factors with which MafB interacts remain uncertain. Bioinformatics methods provide a valuable approach for elucidating the nature of these interactions with transcriptional regulatory elements from a large number of DNA sequences. In particular, identification of patterns of co-occurrence of regulatory <it>cis</it>-elements (motifs) offers a robust approach.</p> <p>Results</p> <p>Here, the directional relationships among several functional motifs were evaluated using the Log-linear Graphical Model (LGM) after extraction and search for evolutionarily conserved motifs. This analysis highlighted GATA-1 motifs and 5’AT-rich half Maf recognition elements (MAREs) in promoter regions of 18 genes that were down-regulated in <it>Mafb</it> deficient macrophages. GATA-1 motifs and MafB motifs could regulate expression of these genes in both a negative and positive manner, respectively. The validity of this conclusion was tested with data from a luciferase assay that used a <it>C1qa</it> promoter construct carrying both the GATA-1 motifs and MAREs. GATA-1 was found to inhibit the activity of the <it>C1qa</it> promoter with the GATA-1 motifs and MafB motifs.</p> <p>Conclusions</p> <p>These observations suggest that both the GATA-1 motifs and MafB motifs are important for lineage specific expression of <it>C1qa</it>. In addition, these findings show that analysis of combinations of evolutionarily conserved motifs can be successfully used to identify patterns of gene regulation.</p

Examining Minimal Important Change of the Self-Assessment Scale of Clinical Reasoning in Occupational Therapy

The purpose of the study was to establish and quantify the minimal important change (MIC) value necessary to determine gains or losses in clinical reasoning during student fieldwork assignments as measured by the Self-Assessment of Clinical Reasoning in Occupational Therapy (SA-CROT). This multicenter prospective longitudinal study was conducted with students on their occupational therapy fieldwork in Japan. Two anchor-based methods were used to estimate the MIC values: a receiver operating characteristic-based method and a predictive modeling-based method. The MIC was adjusted based on the percentage of participants who exhibited improvement. Administered were the SA-CROT and the Global Rating of Change (GRC) scale as an anchor. A total of 111 students from 11 occupational therapy educational programs in Japan responded (response rate 29%). Overall, there was a significant difference (p \u3c .001, effect size was r = .80) in SA-CROT before and after fieldwork, and 81% of students showed improvement in the GRC scale. The adjusted MIC value was 3.69, with 95% confidence interval of 2.29–4.97. This anchor-based, adjusted MIC value is the most reliable value to interpret the changes in SA-CROT before and after fieldwork. The SA-CROT\u27s MIC value can be used as a cut-off point from a learner-centered perspective when considering educational methods and environments in fieldwork

FILM COATING ONTO COHESIVE FINE PARTICLES BY A NOVEL ROTATING FLUIDIZED BED COATER

In this study, film coating onto cohesive fine particles was conducted by using a novel rotating fluidized bed coater (RFBC). In order to avoid the formation of agglomeration, baffle plates were equipped inside the RFBC. Coating experiments were conducted under various operating conditions and the coated particles were evaluated based on their physical properties. As a result, coated particles having extremely small degree of agglomeration and favorable prolonged release property of a tracer material could be obtained

JaCappella Corpus: A Japanese a Cappella Vocal Ensemble Corpus

We construct a corpus of Japanese a cappella vocal ensembles (jaCappella corpus) for vocal ensemble separation and synthesis. It consists of 35 copyright-cleared vocal ensemble songs and their audio recordings of individual voice parts. These songs were arranged from out-of-copyright Japanese children's songs and have six voice parts (lead vocal, soprano, alto, tenor, bass, and vocal percussion). They are divided into seven subsets, each of which features typical characteristics of a music genre such as jazz and enka. The variety in genre and voice part match vocal ensembles recently widespread in social media services such as YouTube, although the main targets of conventional vocal ensemble datasets are choral singing made up of soprano, alto, tenor, and bass. Experimental evaluation demonstrates that our corpus is a challenging resource for vocal ensemble separation. Our corpus is available on our project page (https://tomohikonakamura.github.io/jaCappella_corpus/).Comment: Accepted for ICASSP202
