Therapeutic touch : the use of photo-based methodology as a healing practice within the context of healthcare

This thesis describes the relationship between photography and healthcare in order to examine the model of practice generated by the concept of Photo Therapy, an approach developed by the celebrated British artist- photographer Jo Spence (1934-1992) who saw previously unexplored therapeutic dimensions to the act of taking photographic self-portraits (Spence, 1986). Spence sought visual ways of exploring her experiences as she negotiated treatments for her cancer. My aim has been to use this legacy to unders tand how an artist-photographer can be a kind of healer. My research, based on my own practices (which are very different from those of Spence) working as an artist-photographer on projects with the Camphill Village Trust and Northumbria Healthcare NHS Foundation Trust, has attempted to embrace the full range of social activities created by Photo Therapy: from the process of negotiating a shot; to hand printing the resulting photograph, to the discussions created by viewing photographs with patients, relatives and healthcare staff; to the remote reception of Photo Therapy images by exhibition-going audiences and readers of photographic publications. The context of my research project is the emergent character of Photo Therapy in Japan. My ambition has been to transfer the knowledge developed in the UK to my home country which still has some way to go before it can claim to possess a distinct arts and healthcare sector (Seki, Inoue and Miwaki, 2002). To achieve this goal I have adopted the terminology and methods of Transactional Analysis (TA), a form of psychotherapy that treats all social transactions as derivatives of a parent’s physical contact with its child, e.g. the healing ‘stroke’ of a mother’s hand (Berne, 1961). This form of therapy is familiar to many Japanese and, having applied TA concepts such as Ego States and Stroke Exchanges to my own transactions in healthcare contexts in the UK, I then sketch out my plans for using TA to promote Photo Therapy through my role as a founder member of the Japanese Photo -Therapists Network (JPTN), my country’s first group of photographers and doctors interested in practicing Photo Therapy

分子内結合が調節するJRABのLIMドメインによるアクチン細胞骨格の再編成

JRAB/MICAL-L2 is an effector protein of Rab13, a member of the Rab family of small GTPase. JRAB/MICAL-L2 consists of a calponin homology domain, a LIM domain, and a coiled-coil domain. JRAB/MICAL-L2 engages in intramolecular interaction between the N-terminal LIM domain and the C-terminal coiled-coil domain, and changes its conformation from closed to open under the effect of Rab13. Open-form JRAB/MICAL-L2 induces the formation of peripheral ruffles via an interaction between its calponin homology domain and filamin. Here, we report that the LIM domain, independent of the C-terminus, is also necessary for the function of open-form JRAB/MICAL-L2. In mechanistic terms, two zinc finger domains within the LIM domain bind the first and second molecules of actin at the minus end, potentially inhibiting the depolymerization of actin filaments (F-actin). The first zinc finger domain also contributes to the intramolecular interaction of JRAB/MICAL-L2. Moreover, the residues of the first zinc finger domain that are responsible for the intramolecular interaction are also involved in the association with F-actin. Together, our findings show that the function of open-form JRAB/MICAL-L2 mediated by the LIM domain is fine-tuned by the intramolecular interaction between the first zinc finger domain and the C-terminal domain

Tumour resistance in induced pluripotent stem cells derived from naked mole-rats

The naked mole-rat (NMR, Heterocephalus glaber), which is the longest-lived rodent species, exhibits extraordinary resistance to cancer. Here we report that NMR somatic cells exhibit a unique tumour-suppressor response to reprogramming induction. In this study, we generate NMR-induced pluripotent stem cells (NMR-iPSCs) and find that NMR-iPSCs do not exhibit teratoma-forming tumorigenicity due to the species-specific activation of tumour-suppressor alternative reading frame (ARF) and a disruption mutation of the oncogene ES cell-expressed Ras (ERAS). The forced expression of Arf in mouse iPSCs markedly reduces tumorigenicity. Furthermore, we identify an NMR-specific tumour-suppression phenotype—ARF suppression-induced senescence (ASIS)—that may protect iPSCs and somatic cells from ARF suppression and, as a consequence, tumorigenicity. Thus, NMR-specific ARF regulation and the disruption of ERAS regulate tumour resistance in NMR-iPSCs. Our findings obtained from studies of NMR-iPSCs provide new insight into the mechanisms of tumorigenicity in iPSCs and cancer resistance in the NMR

Aortic Valve Replacement in Anomalous Aortic Origin of Right Coronary Artery

A 75-year-old man with severe aortic regurgitation was referred to our department for surgery. Coronary angiography revealed 75% stenosis at left coronary artery( LAD) and a normally positioned left coronary artery. However, the location of the right coronary artery was anomalous. The right coronary artery ostium originated from the ascending aorta above the left coronary cusp. Emergency surgery proceeded to address severe dyspnea due to congestive heart failure. The higher portion of the right coronary artery was incised in sigmoid fashion, the aortic valve was replaced with a 23-mm stented bioprosthesis and coronary bypass grafting proceeded. The postoperative course was uneventful

Hemolytic Anemia soon after Replacement of Ascending Aorta for acute Aortic Dissection

A 61-year-old female underwent replacement of the ascending aorta for Type A aortic dissection, then gradually developed severe hemolytic anemia over 1 month. The cause of hemolysis was found to be mechanical damage of red blood cells caused by an inverted felt strip at the proximal anastomosis. A reoperation for resection of the felt and repair of the proximal anastomosis successfully resolved the problem. Here, we report a rare case of hemolytic anemia at the site of an inverted felt strip that occurred after replacement of the ascending aorta

Modified Bentall operation with bioprosthetic valve and Valsalva graft conduit:the "slit skirt" technique

We elucidated the efficacy of the slit skirt technique to prevent bleeding from the proximal anastomosis between the graft and aortic annulus. Between September 2008 and September 2014, 15 patients underwent a modified Bentall operation with the slit skirt technique at our institution. No patients had bleeding from the proximal anastomosis. No re-thoracotomy for bleeding was required. During midterm follow-up (median period, 21 months), no patient had pseudoaneurysms at the proximal suture line. We conclude that the slit skirt technique is useful to prevent bleeding from the proximal anastomosis after the Bentall operation
