Measuring Japanese mothers' perception of child abuse: development of a Japanese version of the child abuse blame scale – physical abuse (CABS-PA-J)

<p>Abstract</p> <p>Background</p> <p>The Child Abuse Blame Scale – Physical Abuse (CABS-PA) was translated into Japanese and its subscale items modified by the authors according to the Japanese cultural context. The aim of the current study was to investigate the appropriateness, reliability, and clinical applicability of the CABS-PA Japanese version (CABS-PA-J). Modifications were made to enable the determination of child abuse recognition in a Japanese cultural setting and early clinical intervention in child abuse cases.</p> <p>Methods</p> <p>The CABS-PA text was translated into Japanese, then back translated. The appropriateness of scale item translations was verified based on e-mail discussions with the original CABS-PA author. Exploratory and confirmatory factor analyses were performed to examine the validity of CABS-PA-J responses and to confirm the validity of factor structure. Criterion-related validity was also confirmed. The Japanese scale was used to examine the characteristic differences between mothers of premature infants (< 1500 g) and those of other infants (≧ 1500 g).</p> <p>Results</p> <p>Exploratory and confirmatory factor analyses found the factor structure to be similar between the original scale and the translated CABS-PA-J, suggesting adequate factor validity. There was a statistically significant correlation between social support from a spouse or third party and the abuse score on a subscale, partially demonstrating criterion-referenced validity. Similarities and differences were found in the stress reactions of the mothers of premature infants (< 1500 g) and those of other infants (≧ 1500 g).</p> <p>Conclusion</p> <p>CABS-PA-J was shown to be appropriate and reliable. It is an effective tool for determining the recognition of child abuse among Japanese mothers.</p

13C-NMR Spectroscopic Study on Chemical Species in Piperazine−Amine−CO2−H2O System before and after Heating

AbstractChemical reactions associated with the absorption of CO2 into aqueous solutions of blends of piperazine (PZ) with N- methyldiethanolamine (MDEA), etc. were studied by 13C-NMR spectroscopy. The coexistence of PZ and MDEA enhanced the initial apparent rate of HCO3−/CO2−3 formation. This result can be explained by considering that PZ−monocarbamate rapidly formed works as an organocatalyst in the formation reaction of HCO−3. Concentration changes of chemical species in CO2-absorbed aqueous amine solutions upon heating (80°C, 30min) were studied by 13C-NMR spectroscopy. Carbon dioxide regeneration originates mainly from HCO3−/CO3, and not form carbamate and carbonate

Effect of Electrical Stimulation on Quadriceps Muscle Strengthening Following Reconstructive Surgery of the Anterior Cruciate Ligament

The purpose of this study was to compare the effectiveness of both electrical stimulation and isometric exercise with that of isometric exercise alone on the quadriceps muscle in 30 patients who had undergone anterior cruciate ligament (ACL) reconstruction. The 30 patients were divided into two groups. The electrical stimulation (ES) group (N=18) carried out isometric contraction with ES. The non-ES group (N=12) performed isometric contraction only. The patients were examined clinically in terms of thigh circumference and time from surgery to disappearance of extension lag and giving way. The ES group had better muscle function within these clinical parameters. This study indicated that ES is a useful technique for muscle strengthening after ACL reconstruction

Microfungi associated with withering willow wood in ground contact near Syowa Station, East Antarctica for 40 years

Data are rather lacking on the diversity of microfungi associated with exotic plant substrates transported to continental Antarctica. We examined the diversity and species composition of microfungi associated with withering woody shoots of saplings of Salix spp. (willows) transplanted and in ground contact near Syowa Station, East Antarctica for more than 40 years. The willow saplings originated from Hokkaido, Northern Japan, and were experimentally transplanted in 1967–1968, but died within a few years. Dead willow shoots, unbranched and standing on bare ground for approximately 50 years, were used for the isolation of fungi with the surface disinfection method. A total of 43 isolates were retrieved from 32 (78 %) of the 41 shoots tested. The fungal isolates were classified into 18 molecular operational taxonomic units (MOTUs) based on the similarity of rDNA ITS sequences at the 97 % criterion. Leotiomycetes was the most common class in terms of the number of isolates and MOTUs, followed by Dothideomycetes, Sordariomycetes, and Eurotiomycetes. Molecular phylogenetic affinities suggested that the closest relatives of the MOTUs were saprobic and root-associated fungi. The result of the present study suggested that Cadophora luteo-olivacea is widespread in soils throughout Antarctica and likely indigenous

Wide-bandgap GaN-based watt-class photonic-crystal lasers

青色GaN系フォトニック結晶レーザーの高出力・高ビーム品質動作に成功 --次世代の高品位レーザー加工、高輝度照明、水中LiDAR等の実現に向けて--. 京都大学プレスリリース. 2022-11-04.Short-wavelength (blue-violet-to-green) lasers with high power and high beam quality are required for various applications including the machining of difficult-to-process materials and high-brightness illuminations and displays. Promising light sources for such applications are wide-bandgap GaN-based photonic-crystal surface-emitting lasers (PCSELs), which are based on two-dimensional resonance in the photonic crystal. Developments of these devices have lagged behind those of longer-wavelength GaAs-based PCSELs, because device designs for achieving robust two-dimensional resonance and a nanofabrication process that avoids introducing disorders have remained elusive for wide-bandgap GaN-based materials. Here, we address these issues and successfully realize GaN-based PCSELs with high, watt-class (>1 W) output power and a circular, single-lobed beam with a very narrow (~0.2°) divergence angle at blue wavelengths. In addition, we demonstrate continuous-wave operation with a high output power (~320 mW) and a high beam quality (M²~1). Our results will enable the use of GaN-based PCSELs in the above-mentioned applications

Lateral–Medial Dissociation in Orbitofrontal Cortex–Hypothalamus Connectivity

The orbitofrontal cortex (OFC) is involved in cognitive functions, and is also closely related to autonomic functions. The OFC is densely connected with the hypothalamus, a heterogeneous structure controlling autonomic functions that can be divided into two major parts: the lateral and the medial. Resting-state functional connectivity has allowed us to parcellate the cerebral cortex into putative functional areas based on the changes in the spatial pattern of connectivity in the cerebral cortex when a seed point is moved from one voxel to another. In the present high spatial-resolution fMRI study, we investigate the connectivity-based organization of the OFC with reference to the hypothalamus. The OFC was parcellated using resting-state functional connectivity in an individual subject approach, and then the functional connectivity was examined between the parcellated areas in the OFC and the lateral/medial hypothalamus. We found a functional double dissociation in the OFC: the lateral OFC (the lateral orbital gyrus) was more likely connected with the lateral hypothalamus, whereas the medial OFC (the medial orbital and rectal gyri) was more likely connected with the medial hypothalamus. These results demonstrate the fundamental heterogeneity of the OFC, and suggest a potential neural basis of the OFC-hypothalamic functional interaction

Impaired Relaxation in Induced Pluripotent Stem Cell-Derived Cardiomyocytes with Pathogenic TNNI3 Mutation of Pediatric Restrictive Cardiomyopathy

Wang R., Hasegawa M., Suginobe H., et al. Impaired Relaxation in Induced Pluripotent Stem Cell-Derived Cardiomyocytes with Pathogenic TNNI3 Mutation of Pediatric Restrictive Cardiomyopathy. Journal of the American Heart Association 13, e032375 (2024); https://doi.org/10.1161/JAHA.123.032375.BACKGROUND: Restrictive cardiomyopathy (RCM) is characterized by impaired diastolic function with preserved ventricular contraction. Several pathogenic variants in sarcomere genes, including TNNI3, are reported to cause Ca²⁺ hypersensitivity in cardiomyocytes in overexpression models; however, the pathophysiology of induced pluripotent stem cell (iPSC)-derived cardiomyocytes specific to a patient with RCM remains unknown. METHODS AND RESULTS: We established an iPSC line from a pediatric patient with RCM and a heterozygous TNNI3 missense variant, c.508C>T (p.Arg170Trp; R170W). We conducted genome editing via CRISPR/Cas9 technology to establish an isogenic correction line harboring wild type TNNI3 as well as a homozygous TNNI3-R170W. iPSCs were then differentiated to cardio-myocytes to compare their cellular physiological, structural, and transcriptomic features. Cardiomyocytes differentiated from heterozygous and homozygous TNNI3-R170W iPSC lines demonstrated impaired diastolic function in cell motion analyses as compared with that in cardiomyocytes derived from isogenic-corrected iPSCs and 3 independent healthy iPSC lines. The intracellular Ca²⁺ oscillation and immunocytochemistry of troponin I were not significantly affected in RCM-cardiomyocytes with either heterozygous or homozygous TNNI3-R170W. Electron microscopy showed that the myofibril and mitochondrial structures appeared to be unaffected. RNA sequencing revealed that pathways associated with cardiac muscle development and contraction, extracellular matrix-receptor interaction, and transforming growth factor-β were altered in RCM-iPSC-derived cardiomyocytes. CONCLUSIONS: Patient-specific iPSC-derived cardiomyocytes could effectively represent the diastolic dysfunction of RCM. Myofibril structures including troponin I remained unaffected in the monolayer culture system, although gene expression profiles associated with cardiac muscle functions were altered
