Tuberculous otitis media(TOM) is a rare manifestation caused by Mycobacterium tuberculosis with low incidence rates among extrapulmonary tuberculosis cases. Diagnosis is often delayed because of the presence of several clinical manifestations and the high prevalence of secondary bacterial infections. Few reports have attributed secondary bacterial infections in patients with TOM to commensal Neisseria. Thus, understanding the pathogenic mechanisms and clinical features of commensal Neisseria is important, considering its recent presentation as an infection-causing pathogen. Neisseria mucosa is a commensal inhabitant in humans and is generally considered non-pathogenic but can cause infection in rare cases. Here, we report an atypical secondary infection caused by Neisseria mucosa in an 81-year-old woman with TOM being treated for pulmonary tuberculosis. Direct purulent otorrhea smear microscopy revealed no acid-fast bacilli using Ziehl-Neelsen staining, whereas the phagocytosis of gram-negative cocci by white blood cells was confirmed using Gram staining. Otorrhea culture revealed the growth of N. mucosa. Subsequently, M. tuberculosis infection in the otorrhea was identified using a culture-based method. Vigilance is critical for the early detection of TOM to prevent further complications. This report raises awareness regarding TOM and provides insight into the pathogenicity of N. mucosa in otitis media.

Purpose: Frailty is a state of declined vitality of the body and mind with age in which life functions are impaired. In addition, there is a difference in the susceptibility of older women to frailty compared with that of older men. Therefore, assessing and encouraging physical activity in older adults before they become frail is essential. We aimed to clarify the relationship between calf circumference and body composition and assess the potential association between calf circumference and physical activity indices in older women. Methods: This cross-sectional study included 18 healthy older adults (age 69.0 ± 5.7 years). The physical characteristics, calf circumference, body composition, calf muscle thickness, and physical activity questionnaire that included items on exercise-related activity thermogenesis (EAT) and nonexercise activity thermogenesis (NEAT) were assessed. The association between calf circumference and these additional measures was examined. Results: Positive and significant correlations were found between the calf circumference and body weight, body mass index (BMI), skeletal muscle mass, skeletal muscle mass index, calf muscle thickness, total questionnaire score, and NEAT score (r = 0.66 - 0.87). However, no significant correlations were observed between the calf circumference and EAT scores. Conclusion: Calf circumference in older women may reflect NEAT activity. Improving NEAT activity is an important health-promoting factor in older women.

Objective: This study aimed to evaluate the immediate psychological effects of coordination exercises on women in Japan. Methods: The subjects were 17 adult women (height, 160.1 ± 5.1 cm;weight, 54.3 ± 10.5 kg;age, 57.8 ± 8.3 years) living in the community and attending a fitness club. The subjects performed a coordination exercise called Life Kinetik®. The subjects responded to the Two-Dimensional Mood Scale–Short Term before and after performing 30 minutes of Life Kinetik®. The results were tabulated and four psychological states were calculated (i.e., vitality, stability, pleasure, and arousal). The pre- and post-implementation results were statistically analyzed using a corresponding t-test. Results: Significant differences were found in activation and arousal levels, but not in stability and comfort levels. Conclusion: The coordination exercise, Life Kinetik®, was found to be an exercise program with potential psychological benefits, as it could change women’s psychological condition to active and excited states.

Diffusion and collective motion of rotlets in 2D space

引用

Chinese Physics B 2020年第6期29卷 37-43页

作者： Daiki Matsunaga takumi Chodo Takuma Kawai Graduate School of Engineering Science Osaka University5608531 OsakaJapan

We investigate the collective motion of rotlets that are placed in a single plane. Due to the hydrodynamic interactions,the particles move through the two-dimensional(2D) plane and we analyze these diffusive motions. By analyzing the scaling of the values, we predict that the diffusion coefficient scales with φ0.5, the average velocity with φ, and relaxation time of the velocity autocorrelation function with φ-1.5, where φ is the area fraction of the particles. In this paper, we find that the predicted scaling could be seen only when the initial particle position is homogeneous. The particle collective motions are different by starting the simulation from random initial positions, and the diffusion coefficient is the largest at a minimum volume fraction of our parameter range, φ = 0.05. The deviations based on two initial positions can be explained by the frequency of the collision events. The particles collide during their movements and the inter-particle distances gradually increase. When the area fraction is large, the particles will result in relatively homogeneous configurations regardless of the initial positions because of many collision events. When the area fraction is small(φ < 0.25), on the other hand, two initial positions would fall into different local solutions because the rare collision events would not modify the inter-particle distances drastically. By starting from the homogeneous initial positions, the particles show the maximum diffusion coefficient at φ≈ 0.20. The diffusion coefficient starts to decrease from this area fraction because the particles start to collide and hinder each other from a critical fraction ~23%. We believe our current work contributes to a basic understanding of the collective motion of rotating units.

Hevin/Sparcl1(hereafter referred to as Hevin)is an extracellular matrix protein encoded by the SPARCL1 ***,it has been revealed that Hevin has various functions,such as synapse formation,neuronal migration,inflammation,and angiogenesis(Gongidi et al.,2004;Naschberger et al.,2016;Singh et al.,2016;Liu et al.,2021).In addition,genome-wide association studies uncovered de novo and familial mutations of the SPARCL1 gene associated with a risk for autism spectrum disorder(ASD)(De Rubeis et al.,2014).However,the relationship between ASD-associated Hevin mutant and cellular phenotype has not been ***,we have reported that ASD-associated mutation in Hevin reduces secretion efficiency and induces endoplasmic reticulum(ER)stress caused by structural instability(Taketomi et al.,2022).In this perspective,we discuss the relationship between the molecular functions of Hevin and ASD risk(Figure 1A).Also,we introduce our recent findings that link ASD-associated Hevin mutant to the cellular phenotype of ASD.
