Open Journal of Stomatology 2016年第12期6卷 252-260页

The periodontal ligament (PDL) contains oxytalan fibers as well as collagen fibers, which helps it to withstand the mechanical stress to which it is constantly exposed. The oxytalan fibers are produced by PDL fibroblasts. However, the arrangement of PDL fibroblasts and the orientation of oxytalan fibers relative to the fibroblast cell axis have not been investigated under the condition of mechanical stress. We hypothesized that such stress would alter the arrangement and orientation of these cells and their oxytalan fibers. The aim of this study was to evaluate the effects of stretching strain on PDL fibroblasts, focusing on the cellular arrangement and orientation of oxytalan fibers relative to the long cell axis in cell/matrix layers by staining the major component of the fibers, fibrillin-1. The angle between the long cell axis and the oxytalan fibers was approximately 70 degrees under both non-stretching and stretching conditions. Moreover, stretching induced the rearrangement of the cells. This is the first study to demonstrate that stretching induces the rearrangement of the PDL fibroblasts without altering the angle between the long cell axis and the oxytalan fibers. These results may reflect the orientation of oxytalan fibers in the PDL under the condition of mechanical stress.

Meningoencephalitis secondary to Listeria monocytogenes (L. monocytogenes) mainly affects newborns, the elderly and immunocompromised people;there are extremely rare cases in which said infection occurs in immunocompetent individuals. We present the case of a young adult patient without immunocompromise, who developed meningoencephalitis due to L. monocytogenes;This case is exceptional, since it occurred in an individual outside the classic age group, in addition to not having risk factors, which is why it should be considered an atypical causal agent.

On the Asymptotic Stability of Discrete Crocodilians Model

引用

Advances in Pure Mathematics 2023年第5期13卷 211-225页

作者： kaori Saito Yoshihiro Hamaya Meise University Tokyo Japan Okayama University of Science Okayama Japan

The sex ratio of crocodiles is strongly biased towards females, often as high as 10 females to 1 male. In crocodilians, the temperature of egg incubation is the environmental factor determining sex. If the temperature is low, around 30˚C, the hatchlings are all females. Higher temperature, around 34˚C, hatch all males. This study was made to consider the asymptotic stability of a positive equilibrium point in a nonlinear discrete model of the basic nesting population model, which is described in three-region depending on the temperature of egg incubation. This model is based on key life-historical data and Murray’s research. To study above, we have applied the classical linearization method and P. Cull’s method and moreover, we employ non-standard discretization methods for later our Equations (6)-(8) and (15).

Pain in Non-Athlete Patients Undergoing Hip Arthroscopy for Femoroacetabular Impingement and Hip Labral Tears: A Longitudinal Study

引用

Health 2023年第9期15卷 990-1002页

作者： kaori Sano Yuko Uesugi Hidetsugu Ohara Graduate School of Health Sciences Kobe University Kobe Japan Department of Nursing Kinjo Gakuin University Nagoya Japan Department of Orthopedic Surgery Hirakata City Hospital Hirakata Japan

Background: Pain in patients with orthopedic problems is an important aspect of surgical evaluation. However, the effect on the quality of life depends not only on the degree of pain but also on its type. Hip arthroscopy has been performed for hip joint symptoms caused by femoroacetabular impingement (FAI) and hip labrum tears. However, the degree and type of pain after hip arthroscopy remains unknown. Objective: This study aimed to clarify the degree and type of pain during 6 months after hip arthroscopy. Methods: Non-athlete patients aged 20 - 65 years who underwent hip arthroscopy between December 2018 and October 2019 participated in a questionnaire survey before hospitalization and at 1, 3, and 6 months after surgery. The questionnaire comprised the Japanese Orthopaedic Association Hip-Disease Evaluation Questionnaire (JHEQ) for quality of life, International Physical Activity Questionnaire (IPAQ) for activities, and the Short-Form McGill Pain Questionnaire (SF-MPQ-2) for pain. Results: The analysis included 10 patients (men: 4, women: 6, mean age: 38 ± 8.6 years, FAI: 6 cases, hip labrum tears: 4 cases). The average time from symptom onset to surgery was 26.9 ± 19.0 months. The analysis from before surgery to 6 months after surgery showed improvement over time in all scale scores (JHEQ, IPAQ, and SF-MPQ-2). The degree of pain was significantly improved based on the JHEQ visual analog scale evaluation (P = 0.019) 3 months after surgery. Significant improvement in intermittent pain (P = 0.011) based on SF-MPQ-2 was noted 3 months after surgery;however, no significant improvement in continuous pain was noted. Conclusions: Patients who underwent hip arthroscopy showed significant improvements in the degree of pain and type of intermittent pain from before surgery to 3 months after surgery, however, no change was observed in continuous pain.

Dirac reduction of binary asteroid systems with symmetry and stability of relative equilibria

引用

Theoretical & Applied Mechanics Letters 2013年第1期3卷 81-88页

作者： kaori Onozaki Hiroaki Yoshimura Major in Applied Mechanics Graduate School of Fundamental Science and Engineering Waseda University Department of Applied Mechanics and Aerospace Engineering Waseda University

In this paper, we study symmetry reduction for a binary asteroid system modeled by a rigid body and a particle. In particular, we demonstrate how translational and rotational symmetry reduction appeared in the binary asteroid system can be carried out in the context of Dirac reduction by stages and with the associated reduction of implicit Hamiltonian systems. Then we investigate Stability of relative equilibria of the asteroid pair and show stability regions by using the energy-momentum method. Lastly, we illustrate some numerical simulations for stable and unstable orbits near from relative equilibria of the Collinear and T configurations.C 2013 The Chinese Society of Theoretical and Applied Mechanics.
