Single-cell RNA sequencing (scRNA-seq) has been widely applied to provide insights into the cell-by-cell expression difference in a given bulk sample. Accordingly, numerous analysis methods have been developed. As it involves simultaneous analyses of many cell and genes, efficiency of the methods is crucial. The conventional cell type annotation method is laborious and subjective. Here we propose a semi-automatic method that calculates a normalized score for each cell type based on user-supplied cell type-specific marker gene list. The method was applied to a publicly available scRNA-seq data of mouse cardiac non-myocyte cell pool. Annotating the 35 t-stochastic neighbor embedding clusters into 12 cell types was straightforward, and its accuracy was evaluated by constructing co-expression network for each cell type. Gene Ontology analysis was congruent with the annotated cell type and the corollary regulatory network analysis showed upstream transcription factors that have well supported literature evidences. The source code is available as an R script upon request.

This study was a cross-sectional reaserch that analyzed the effect of emotional expression type on happiness level with structured questionnaires. A total of 186 participants in the study were in their 20s to 60s. Data collection was received from those who voluntarily agreed to the study from September 1 to 15, 2021. The collected data were frequency analysis, t-test, and regression analysis with spss 18.0. As a result of the analysis, it was found that people who perform superficial acts disguised as emotions were less satisfied with their current life (t=-10.482, p<0.01). People who do inner behavior showed high levels of happiness. These results suggest the following: It can be seen that in order to improve effective happiness, it is required to actively and truthfully act in a physical environment.

GTP cyclohydrolase I (GTPCH) is a key enzyme in the de novo synthesis of tetrahydrobiopterin. Previously, the Drosophila melanogaster GTPCH gene has been shown to be expressed from two different promoters (P1 and P2). In our study, the 5'-flanking DNA regions required for P1 and P2 promoter activities were characterized using transient expression assay. The DNA regions between -98 and +31, and between -73 and +35 are required for efficient P1 and P2 promoter activities, respectively. The regions between -98 and -56 and between -73 and -41 may contain critical elements required for the expression of GTPCH in Drosophila. By aligning the nucleotide sequences in the P1 and P2 promoter regions of the Drosophila melanogaster and Drosophila virilrs GTPCH genes, several conserved elements including palindromic sequences in the regions critical for P1 and P2 promoter activities were identified. Western blot analysis of transgenic flies transformed using P1 or P2 promoter-lacZ fusion plasmids further revealed that P1 promoter expression is restricted to the late pupae and adult developmental stages but that the P2 promoter driven expression of GTPCH is constitutive throughout fly development. In addition, X-gal staining of the embryos and imaginal discs of transgenic flies suggests that the P2 promoter is active from stage 13 of embryo and is generally active in most regions of the imaginal discs at the larval stages.

The creative fashion design is the technique which ran be obtained through the structural analysis of the relationship between principle, element-combination and idea-expression. In the research, as the results of theoretical survey of design structure and idea-expression, the structural and subjective designs are classified and defined: a. the structural design is analyzed with the existing examples based on the combinational Idea-expression of the O.C.L method, and b. the subjective design is also analyzed connecting the real examples to Cordon method, Synetic method, Association method, and expansive idea-expression-method obtained by the Experiences of Geometrical Combinations. The research can be summarized as follows: 1. The creative fashion design which emphasizes the geometrical structure utilizes the modification method whirh combines the shapes and constructs extraordinary structural beauty coming from the complex structural principle, that is, emphasis and balance. 2. The creative fashion design which emphasizes specific subjects utilizes the modification method which mimics representative and plastic resemblances and constructs symbolic structural beauty coming from the simple structural principle, that is, material elements.

Type I and type II collagens are considered the major collagens of bone and cartilage respectively. Monitoring the patterns of those gene and protein expressions during development will provide a basis for the understanding of the normal and abnormal growths. This study was undertaken to investigate the expression of collagen genes and proteins involved in the developing human mandible. Fifty embryos and fetuses were studied with Alcian blue-PAS, Masson's Trichrome, reverse transcription polymerase chain reaction (RT-PCR), Western blot analysis, and Southern blot analysis. Our results showed that $pro-{\alpha}1(II)$ collagen gene expression begins in the 5th week. Type II collagen is synthesized in mesenchymal cells in advance: of overt chondrogenesis. The gene expression for type II collagen was highest during the appearance of Meckel's cartilage. There was a switch in collagen protein expression from type I to type II during the appearance stage of Meckel's cartilage. The distribution of the mRNA for type II collagen corresponded well with the pattern of type II collagen protein. The endochondral ossification was observed where there was direct replacement of cartilage by bone.

Purpose: The purpose of this study was to investigate the ability of Mineral trioxide aggregate(MTA) to support osteoclastic differentiation from fetal rat calvarial cell. Methods: In this study, response of IL-6, RANKL, and OPG in fetal rat calvarial cells stimulated with IL-$1{\beta}$ on MTA was evaluated by ELISA and RT-PCR. Results: The results were as follows; there was no significant difference between glass and MTA at 5days. In ELISA analysis, Glass group and MTA group showed similar IL-6 expression, Glass+IL-$1{\beta}$ group and MTA+IL-$1{\beta}$ group showed similar IL-6 expression. In RT-PCR analysis, Glass group and MTA group showed similar IL-6, RANKL, OPG mRNA expression, MTA+IL-$1{\beta}$ group and Glass+IL-$1{\beta}$ group showed 3 fold increase of IL-6 and RNAKL mRNA expression when compared with MTA group. All groups showed similar OPG mRNA expression. Conclusions: MTA does not suppress cell proliferation and increase the proinflammatory cytokine that induce osteoclastogenesis. Thus, MTA is biocompatible material that could be used in various clinical conditions.

Metal pollution of aquatic ecosystems is a problem of economic and health importance. Information regarding molecular responses to metal exposure is sorely needed in order to identify potential biomarkers. To determine the effects of heavy metals on chironomids, the full-length cDNA of alcohol dehydrogenase (ADH3) from Chironomus riparius was determined through molecular cloning and rapid amplification of cDNA ends (RACE). The expression of ADH3 was analyzed under various cadmium and copper concentrations. A comparative and phylogenetic study among different orders of insects and vertebrates was carried out through analysis of sequence databases. The complete cDNA sequence of the ADH3 gene was 1134 bp in length. The sequence of C. riparius ADH3 shows a low degree of amino acid identity (around 70%) with homologous sequences in other insects. After exposure of C. riparius to various concentrations of copper, ADH3 gene expression significantly decreased within 1 hour. The ADH3 gene expression was also suppressed in C. riparius after cadmium exposure for 24 hour. However, the effect of cadmium on ADH3 gene expression was transient in C. riparius. The results show that the suppression of ADH3 gene by copper exposure could be used as a possible biomarker in aquatic environmental monitoring and imply differential toxicity to copper and cadmium in C. riparius larvae.

ELDF15, homologous with AT2 receptor-interaction protein 1 (ATIP1), may play an important role in cell differentiation, proliferation, and carcinogenesis. We aimed to understand the biological function of ELDF15 via construction and transfection of a recombinant expression vector containing antisense ELDF15. Recombinant expression vectors were successfully constructed and transfected into K562 cells. A stable transfectant, known as pXJ41-asELDF15, stably produced antisense ELDF15. Compared with K562 and K562-zeo cells, K562-pXJ41-asELDF15 cells showed inhibition of cell proliferation. RT-PCR analysis showed that the expression and protein level of ELDF15 decreased significantly in K562 cells transfected with pXJ41-asELDF15. Expression of hemoglobin increased in K562 cells transfected with pXJ41-asELDF15 by benzidine staining. increases NBT reduction activity in K562 cells transfected with pXJ41-asELDF15.Colony forming efficiency in two-layer soft agar was clearly inhibited as assessed by electron microscopy. These results suggest that ELDF15 plays a potential role in cell differentiation, proliferation and carcinogenesis.

We previously showed that Asb-4 and Asb-17 is uniquely expressed in developing male germ cells. A recent report showed that Asb-9 is specifically expressed in the kidney and testes; however, detailed expression patterns in developing germ cells have not been shown. Northern blot analysis in various tissues demonstrated that mAsb-9 was strongly expressed in the testes. Expression analysis by RT-PCR and Northern blot in developing mouse testes indicates that mAsb-9 is expressed from the fourth week after birth to adulthood, with the highest expression in round spermatids. Expression sites were further localized by in situ hybridization in the testes. Pachytene spermatocytes and spermatids expressed mAsb-9 but spermatogonia and generated spermatozoa did not. This study reveals that mAsb-9 could be a specific marker of active spermatogenesis and would be useful for studies of male germ cell development.
