Three-dimensional analysis of the arrangement of microtubules of the outer segment in the ciliary-type photoreceptor cell in the Onchidium dorsal eye

Katagiri, Nobuko,Shimatani, Yuichi,Katagiri, Yasuo Korean Society of Photoscience 2002 Journal of Photosciences Vol.9 No.2

The inverted retina of the Onchidium dorsal eye (DE) is composed only of ciliary-type photoreceptor cells (CC's). The outer segment (OS) of the CC is a concentric lamellar structure consisting of many modified ciliary membranes and stains positively with anti-$\beta$-tubulin antibody. Near the base of the OS there are about 30 basal bodies each connecting individually to a cilium. The cilia are rod-shaped at the base, progressing upwards to a flattened sheet-like shape with increasing surface area. Three-dimensional analysis on serial sections demonstrates the ladle-shape of a modified cilium. Many modified cilia wrap around each other like the leaves of a cabbage. Nine pairs of microtubules (MT's) are located regularly in a ring at the base of the cilium, gradually losing their regular arrangement towards the periphery, where they separate into two subgroups that are contained within two swollen portions of a modified cilium. Within the CC of the Onchidium DE, MT's in the modified cilium exist as two poles extending longitudinally in a thin expanded ciliary membrane. This arrangement may support the photoreceptive OS and serve to maintain its structural integrity.

社會保障制度における不正受給 -生活保護を中心に-

The Social Security fund was made of our tax and premium. So, the nature is very public and we are forbidden to receive social security benefit on the base of wrong ways. Public assistant system is funded by 100% tax and there is strict means test before getting the assistance. In this system, trouble on wrong way is sometimes caused by gap of understanding it between the government and recipient. The government prohibit recipient has a car in general. When authority finds out recipient has a car, it give recipient legal sanction, that`s suspension or cancel of public assistance. In the case, the law requires the authority should observe Due Process. It means that when authority gives a sanction, at first the sanction has to be the mildest one. In Social Security system, legal sanction must be taken carefully, keep Due Process and have a regard for recipients.

Angiogenesis in newly regenerated bone by secretomes of human mesenchymal stem cells

Katagiri, Wataru,Kawai, Takamasa,Osugi, Masashi,Sugimura-Wakayama, Yukiko,Sakaguchi, Kohei,Kojima, Taku,Kobayashi, Tadaharu Korean Association of Maxillofacial Plastic and Re 2017 Maxillofacial Plastic Reconstructive Surgery Vol.39 No.-

Background: For an effective bone graft for reconstruction of the maxillofacial region, an adequate vascular network will be required to supply blood, osteoprogenitor cells, and growth factors. We previously reported that the secretomes of bone marrow-derived mesenchymal stem cells (MSC-CM) contain numerous growth factors such as insulin-like growth factor (IGF)-1, transforming growth factor $(TGF)-{\beta}1$, and vascular endothelial growth factor (VEGF), which can affect the cellular characteristics and behavior of regenerating bone cells. We hypothesized that angiogenesis is an important step for bone regeneration, and VEGF is one of the crucial factors in MSC-CM that would enhance its osteogenic potential. In the present study, we focused on VEGF in MSC-CM and evaluated the angiogenic and osteogenic potentials of MSC-CM for bone regeneration. Methods: Cytokines in MSC-CM were measured by enzyme-linked immunosorbent assay (ELISA). Human umbilical vein endothelial cells (HUVECs) were cultured with MSC-CM or MSC-CM with anti-VEGF antibody (MSC-CM + anti-VEGF) for neutralization, and tube formation was evaluated. For the evaluation of bone and blood vessel formation with micro-computed tomography (micro-CT) and for the histological and immunohistochemical analyses, a rat calvarial bone defect model was used. Results: The concentrations of IGF-1, VEGF, and $TGF-{\beta}1$ in MSC-CM were $1515.6{\pm}211.8pg/mL$, $465.8{\pm}108.8pg/mL$, and $339.8{\pm}14.4pg/mL$, respectively. Tube formation of HUVECs, bone formation, and blood vessel formation were increased in the MSC-CM group but decreased in the MSC-CM + anti-VEGF group. Histological findings suggested that new bone formation in the entire defect was observed in the MSC-CM group although it was decreased in the MSC-CM + anti-VEGF group. Immunohistochemistry indicated that angiogenesis and migration of endogenous stem cells were much more abundant in the MSC-CM group than in the MSC-CM + anti-VEGF group. Conclusions: VEGF is considered a crucial factor in MSC-CM, and MSC-CM is proposed to be an adequate therapeutic agent for bone regeneration with angiogenesis.

兒童虐待に關する判例硏究

( Katagiri Yuki ) 아세아여성법학회 2002 아세아여성법학 Vol.5 No.-

In recent years, the increase of child abuse has been featured in the mass media. This is one of hot issue in the field of Social Security Law. Most of child abuse are done by the person with parental authority. Against such a situation, we have some legislations in Japan. Child Welfare Law plays the most important role, and when the case is so serious, the Penal Code can be applied. For dealing with the increase of child abuse, the Law concerning the Prevention of Child Abuse on May 2000. Our actual condition of Child Abuse is as follows. There were l7, 725 consultations(2000) to the child guidance center. The breakdown is physical abuse (49.7%), neglect (36.5) %, sexual abuse(3.7%) and emotional abuse(l0.l%) in 2000. These are done by mother (6L6%), farter (23.7%), stepmother and stepfather followed them. In the case of child abuse, it is desirable to separate the child and their parent. The child Welfare Law provides the some institutions for child who was separated from their parent (§ 27(1)-3). Then the consent from the parent is indispensable far sending the child to the institutions. Bar without this consent, they can send the child there after getting the approval from Family Court(Child Welfare Law § 28). There were 142 applications for the approval in 2000 and 10 1 of them were accepted, When the Child abuse is very serious, the director of child guidance center can ask the loss sentence parental authority for Family Court( § 33-6). In the case for asking the approval on the Child Welfare Law § 28, there are some regal issue. At first, it is whether Family Court can give the comprehensive approval or nor. Concerning this problem, some gave the comprehensive approval, but in most of cases, Family Court expressed the concrete referral. The judgement of the Court of Appeal in fukuoka 1989/4/28 is the leading case in this point. It is not a final solution to separate the .child from their parent. We can say it is the act of necessity. The ultimate goal is reproduction of family. For this purpose, Child Welfare Law § 27(1)-2 provides that the child welfare officer give instruction to the child and parent. Through this article, We can hope they learn how to make a good relationship between them. In addition, the Law concerning the Prevention of Child Abuse provides the heating from the child welfare officer as an important marter of referral rescission. In the cases, we can see some judge expects such an instruction by the child guidance center. Lastly 1 would like to dose this paper by pointing out this. It is that on solving the child abuse, we may not make use of the judiciary proceedings. As stated above, although the number of consultation on child abuse is about 18.000, the application to Family Coon is only 142. We can say this is the reason why most of them are solved at the level of child guidance center. Bur we can also indicate some child guidance center hesitate to apply to Family Court and some Family Court show a negative attitude toward the accept of such an application. Considering the important role of the law playing on relief of child abuse, we should actively use the judiciary proceedings in future.

생활보호제도와 사적부양제도의 합리적 조정

片桐由喜(Katagiri, Yuki) 한국사회보장법학회 2013 사회보장법학 Vol.2 No.2

복지국가를 지향하는 하는 많은 나라들은 국민에게 건강하고 문화적인 최저한도의 생활을 보장하는 책임을 지며, 그 목적을 위해 사회보장입법을 하고, 제도를 정비·발전시킨다. 한편, 복지국가의 기본이념으로서는 국민 자신의 생활이 어려울 때 스스로 해결할 수 없다면 사회보장제도에 의지하기 전에 가족, 즉 사적인 부양으로 생계를 유지해야 한다. 그러나 가족기능이 저하되고, 가족 간의 부양의식도 이전과 비교하였을 때 크게 변화한 시점에서는 사적부양이 공적인 부양에 우선적으로 적용될 수 있는 시스템을 기반으로 한 제도의 설계 역시 검토되어야 한다. 이러한 재검토에 있어서는 생존권을 규정한 헌법 25조뿐만 아니라 개인의 존엄을 보장하는 헌법 13조 역시 고려하면서 사적부양과 공적부양의 관계를 생각할 필요가 있다. The Welfare states in modern society have liability for their nation to give the minimum standard of living based on law. To carry out this task, the states have made and developed social security laws. On the other hand, as the philosophy of welfare states, there are idea of self-help or self-responsibility, therefore we are, of course, required to manage our life by our efforts. It means that when we are in want but cannot maintain our life by ourselves, we have to make use of family support before depending on national social security system. However, it need to rethink such an idea because family has less power to help each other than before. In addition, the sense of support among family has also widely changed now. Rethinking the priority between public assistance and family support, it is very important to put into view not only §25 of Japanese Constitution, that article refers the right of life, but also §13, which declares the nation shall be respected as individuals.

Social Security System is working as a safety net supporting our life. This system gives both livelihood and social participation to especially the elderly and the disabled, so it is big interest for them to get what kind of benefits, how to do. Firstly, it is necessary to know, next, to do action. For them, they have to get information, arrange and select them. And it is sometimes hard for us as well as the elderly and disabled to understand the System. So, all of us need the support from public servant at their offices. If we have no advice and /or suggestion from them, we may have a risk which we cannot receive social security benefits For the reason the residents cannot get advide and information from public servant, recently residents come to bring a court case againg them. The point of cases is that not to give advice and information is illegal or not, and if illegal, what is standard for judge. Through some cases, we can find standard for judge: importance of advice, information disparity between residents and public servant, impact on making a decision, the capacity and effort of resident and the level of Social Security System-spread. There are many cases and resarch about advice and information in the other fields, financial trade, medical office where require informed consents and so on. The study just has begun in the field of social security. We can say the standard is mostly common in all of fields. We have to look for legal remedy for the residents who couldnot receive the benefits without advice.

Masticatory muscle tendon-aponeurosis hyperplasia that was initially misdiagnosed for polymyositis: a case report and review of the literature

Background Masticatory muscle tendon-aponeurosis hyperplasia (MMTAH) is a relatively newly identified clinical condition that manifests as trismus with a square-shaped mandible. Herein, we report a case of MMATH that was initially misdiagnosed for polymyositis due to trismus and simultaneous lower limb pain, with literature review. Case presentation A 30-year-old woman had a history of lower limb pain after exertion for 2 years. Initial physical examination had been performed at the Department of General Medicine in our hospital. There was also redness in the hands and fingers. Although polymyositis was suspected, it was denied. The patient visited our department for right maxillary wisdom tooth extraction. Clinical examination revealed that the patient had a square-shaped mandible. The maximal mouth opening was 22 mm. There was no temporomandibular joint pain at the time of opening. Furthermore, there was awareness of clenching while working. Panoramic radiography revealed developed square mandibular angles with flattened condyles. Computed tomography showed enlarged masseter muscles with high-density areas around the anterior and lateral fascia. Magnetic resonance imaging also showed thickened tendons and aponeuroses on the anterior surface and inside bilateral masseter muscles. Finally, the patient was diagnosed with MMTAH. Bilateral aponeurectomy of the masseter muscles with coronoidectomy and masseter muscle myotomy was performed under general anesthesia. The maximum opening during surgery was 48 mm. Mouth opening training was started on day 3 after surgery. Histopathological examination of the surgical specimen showed that the muscle fibers were enlarged to 60 μm. Immunohistochemistry testing for calcineurin, which was associated with muscle hypertrophy due to overload in some case reports, showed positive results. Twelve months after surgery, the mouth self-opening and forced opening were over 35 mm and 44 mm, respectively. Conclusions Herein, we report a case of MMATH. Lower limb pain due to prolonged standing at work and overload due to clenching were considered risk factors for symptoms onset of MMATH.

日韓兒童虐待法制(일한아동학대법제)의 比較(비교)

The United Nations adopted the Convention on the Right of the Child in 1989 on the assumption that the child has an independent character. We ratified it iol994 and they did it in 1991 in Korea. With this ratification, we have recognized the assault and neglect to their own child is not discipline at home but child abuse in Japan and Korea. The more we understand about the child abuse, the more the reports on it to me authority and police. For dealing with this matter, both countries have prepare a new legal system in 2000. To be concrete, Japanese government enacted ``Child Abuse Prevention Act`` and there was also a complete revision of ``Child Welfare Law`` in Korea. We have so many similarity in our systems that we are facing the same problem in this field. Under our legal system, we can separate the child from their parents for the reason of child abuse. When the authority send the child to some institution for the child, it is necessary to get the consent of their parents. Without the consent but their parents maltreat their child cruelly, the authority can send the battered child to an institution by having the approval of a family court. In addition, we put the person engaged in a specific occupation under an obligation to report the face of abuse, they are teacher, doctor, police and so on. But this obligation is nor legal duty. Even if they find a battered child but not report this fact, we can not punish them. As the final means to rescue a battered child, there is the Joss declaration of parental authority. We have not used this function much because this gives the child a serious impact their future. It is the biggest problem whether we can restrict the parental authority and if can, to what extent we can in case of that the battered child is sheltered in the institution. There is no provision for such a problem in both Japan and Korea. It is desirable to make a legislation and set forth guidelines for resolving the matter. We have firmly had one legal culture, ``the law does not enter the home`` for long time. Owing to this culture, legal system for the child abuse has not been functioned completely yet. However, now, we are required to change the way of thinking, ``the law enters the home`` occasionally. Because the dispute between a married couple, parents/child and family has increased in our time. Without an intervention of law, it is difficult to keep our family peaceful. All of us have to understand the time has changed and our society needs a new consideration for child welfare.

주택보장제도의 현대적 과제

片桐由喜 ( Katagiri Yuki ) 아세아여성법학회 2021 아세아여성법학 Vol.24 No.-

Housing is the base of human life. Nevertheless, we highly depend on private sector, that is the companies or families, for the housing. Because the public responsibility, which means Governmental responsibility, for housing is not sufficient. By the way, as of 2021, many workers are suffering from reduced income or unemployment due to restraining the economic activities forced to prevent infection with the COVID-19. Now, due to reduced income or unemployment, some have lost or are at risk of losing their homes but have not received sufficient housing benefit from public sector. And by (thanks to) COVID-19, we noticed the weakness of public housing benefit in Japan. In the future, it will be necessary to strengthen public involvement in housing supply and develop a universal housing benefit.
