Study of the drawing experience in "Mother and Child Drawings" using PAC Analysis <Article>
The drawing method is widely used in practical scenes of clinical psychology, and attention is being drawn to its therapeutic effects. This study conducted an interview survey using PAC analysis to demonstrate what type of drawing experience can be found in the drawing method, with a focus on "Mother and Child Drawings." As a result, it was demonstrated that the narratives about the internal mother-child relationship of the person who draws, the actual mother-child relationship, the family relationship, or the values of the person who draws could be obtained through conducting Mother and Child Drawings. Also, as a factor due to which various narratives were obtained, it was observed that introspection could easily deepen using PAC analysis, which has a stage of free association. Based on the above, it was suggested that when conducting a Mother and Child Drawing in a practical scene of the clinical psychology, it is therapeutically useful for the person who draws to reflect on their drawing with the interviewer by means of PAC analysis
Development and Practice of a Junior High School History Unit to Promote the Reconstruction of “Historical Significance”: The case of the unit “What criteria should be used to decide the boldface in textbooks?”
This study proposes a history unit plan aimed at the reconstruction of historical significance of junior high school students. In some cases, historically significant items are boldfaced in textbooks by junior high school students. However, as citizens, it is not enough to judge whether or not historical significance is important in a textbook. Therefore, in this study, The Historical Thinking Project (Canada) and The Critical Thinking Consortium’s unit plan were used as a basis for the development and practice of a history unit. This unit aims to reconstruct “historical significance” by 1) understanding the diversity of criteria of “historical significance,” 2) progressing “historical significance,” and 3) reconstructing “historical significance” from a broader perspective. In particular, the textbook’s boldface type was used as a material for the performance task, “Let’s submit an opinion about the boldface type to the textbook writer”, in order to reconstruct historical significance. The outcome of this research hints at future possibilities of bigger reforms in the history curriculum
A Single Amino Acid Substitution in the NS2A Protein of Japanese Encephalitis Virus Affects Virus Propagation In Vitro but Not In Vivo
We identified a unique amino acid of NS2A113, phenylalanine, that affects the efficient propagation of two Japanese encephalitis virus strains, JaTH160 and JaOArS982, in neuroblastoma Neuro-2a cells but not in cell lines of extraneural origin. This amino acid did not affect viral loads in the brain or survival curves in mice. These findings suggest that virus propagation in vitro may not reflect the level of virus neuroinvasiveness in vivo
NS1’ Protein Expression in the JaOArS982 Strain of Japanese Encephalitis Virus Does Not Enhance Virulence in Mice
Using a mouse model, we previously demonstrated that subcutaneous infection with the JaTH160 strain of Japanese encephalitis virus (JEV) causes significantly higher virulence and stronger virus propagation in the brain compared with that of the JaOArS982 strain. We also showed that the JaTH160 strain, but not JaOArS982, expresses the NS1’ protein and that NS1’ enhances JEV production in avian cells and embryonated chicken eggs. In this study, we examined whether NS1’ expression affects virulence in mice infected with the JaOArS982 and JaTH160 strains using the corresponding recombinant viruses S982-IC and JaTH-IC. Expression of the NS1’ protein in S982-IC diminished the mortality in mice, whereas S982-IC viruses without NS1’ caused 40?60% mortality. However, the viral loads in the brains of these mice were not significantly different despite the dvariation in NS1’ expression. JaTH-IC viruses depleted of the NS1’ protein exhibited high mortality levels, similar to those of the virus expressing NS1’. Previous studies showed that the NS1’ protein plays a role in the enhanced virulence of the JEV SA14 strain in mice. However, our current data suggest that NS1’ protein expression in S982-IC reduces, rather than enhances, the mortality in mice. Thus, the effect of NS1’ on pathogenicity in vivo may vary among virus strains. Our data also suggest that the reduced mortality resulting from NS1’ expression in S982-IC is not simply due to viral replication in the brains. Further investigation is needed to uncover the mechanism by which NS1’ affects pathogenicity in JEV-infected animals
Antibacterial Activity of Hypericum Erectum
In recent years, the potential of oral care in preventing aspiration pneumonia has been recognized. Consuming drinks is thought to be an easy and effective method of oral care, and the antibacterial activities of various drinks have been examined. However, the side effects associated with, for example, caffeine as an ingredient in tea (e.g. sleep disorders) need to be taken into consideration. As yet, a safe caffeine-free tea to be taken orally to prevent aspiration pneumonia has not been reported. Thus, in the present study we evaluated the antibacterial effects of hot water extracts of four teas, namely Hypericum Erectum, Crataegus cuneata, Rosa canina, and Matricaria rectita, thought to be caffeine-free. The effects of the extracts against 19 bacteria and 1 fungus were investigated by the dilution plate technique. In addition, the components of the teas were analyzed by HPLC analysis. The strongest antibacterial activity was observed for the hot water extract of H. erectum, which exhibited significant activity against oral bacteria, including Streptococcus oralis. However, the H. erectum extract did not kill microbiota, such as Escherichia coli and Lactobacillus casei. Neither hypericin nor caffeine, both of which have notable side effects, were detected in the H. erectum extract following HPLC analysis. These results suggest that H. erectum tea may be a good candidate for simple, safe oral care to prevent aspiration pneumonia in the elderly
Effect of O-arm for spinal injury
Purpose : To compare the effectiveness of O-arm navigation with that of conventional fluoroscopic guidance in corrective posterior fixation for cervical spinal injury. Methods : This retrospective comparative study involved 11 consecutive patients who underwent corrective posterior fixation using O-arm navigation or conventional fluoroscopy for cervical spinal injury between February 2016 and May 2021. Patient-specific characteristics (age and sex), number of screws, number of pedicle screws, accuracy of pedicle screw insertion, number of vertebral bodies fixed, operating time, and length of hospital stay were analyzed using the t-test. A P-value 0.05). Conclusion : O-arm navigation can improve the accuracy of cervical pedicle screw insertion. Its introduction could expand the indications for use of pedicle screws in posterior fixation of cervical spinal injury beyond those that are possible using conventional fluoroscopy
RNAウイルスに対する迅速な全ゲノム決定法の構築
RNA viruses are the etiological agents of many infectious diseases. Since RNA
viruses are error-prone during genome replication, rapid, accurate and economical
whole RNA viral genome sequence determination is highly demanded. Next generation sequencing (NGS) techniques perform whole viral genome sequencing
due to their high-throughput sequencing capacity. However, the NGS techniques
involve a significant burden for sample preparation. Since to generate complete
viral genome coverage, genomic nucleic acid enrichment is required by reverse
transcription PCR using virus-specific primers or by viral particle concentration.
Furthermore, conventional NGS techniques cannot determine the 5′ and 3′
terminal sequences of the RNA viral genome. Therefore, the terminal sequences
are determined one by one using rapid amplification of cDNA ends (RACE).
However, since some RNA viruses have segmented genomes, the burden of the
determination using RACE is proportional to the number of segments. To date,
there is only one study attempting whole genome sequencing of multiple RNA
viruses without using above mentioned methods, but the generated sequences’
accuracy compared to the reference sequences was up to 97% and did not reach
100% due to the low read depth. Hence, we established novel methods, named
PCR-NGS and RCA-NGS, that were optimized for an NGS machine, MinION.
These methods do not require nucleic acid amplification with virus-specific PCR
primers, physical viral particle enrichment, and RACE. These methods enable
whole RNA viral genome sequencing by combining the following techniques: (1)
removal of unwanted DNA and RNA other than the RNA viral genome by nuclease
treatment; (2) the terminal of viral genome sequence determination by barcoded
linkers ligation; (3) amplification of the viral genomic cDNA using ligated linker
sequences-specific PCR or an isothermal DNA amplification technique, such as
rolling circle amplification (RCA). The established method was evaluated using
isolated RNA viruses with single-stranded, double-stranded, positive-stranded,
negative-stranded, non-segmented or multi-segmented genomes. As a result, all
the viral genome sequences could be determined with 100% accuracy, and these
mean read depths were greater than 2,500×, at least using either of the methods.
This method should allow for easy and economical determination of accurate
RNA viral genomes.権利情報:© 2023 Misu, Yoshikawa, Sugimoto, Takamatsu, Kurosu, Ouji, Yoshikawa, Shimojima, Ebihara and Saijo.
