Re-thinking the public domain using interstitial space in NYC

Thesis (M. Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 2010.Cataloged from PDF version of thesis.Includes bibliographical references (p. 84-85).This thesis aims to rethink the notion of public space and civic duty in the city. By using interstitial, underused spaces, without disputing present urban and legal status, the thesis wants to accomodate services for the people who might otherwise be ignored in the city, while using the potential of the site itself to offset the cost of these services. Looking at a site in New York City, between Pennsylvania Station and the Hudson River, the thesis introduces diverse and temporary programs in a sequence of interstitial spaces as a tool to integrate the homeless issue in the dynamic of the city. The aim is to encourage public intervention that soften the threshold between disparate urban classes, while fulfilling several civic functions, the most important of which is to explore new, safe, and dignified designs for homeless shelters. In the process, the thesis attempts to recognize the specificity of individual dealing with time and space, which are becoming more and more homogenized in the capitalist society.by Mio Uchida.M.Arch

Health benefits of serious involvement in leisure activities among older Korean adults

The existing literature suggests that serious engagement in leisure activities leads to happiness, life satisfaction, and successful aging among older adults. This qualitative study was used to examine the benefits of serious involvement in leisure activities among older Korean adults who were members of a sports club. Using an analytic data analysis, we identified three main themes associated with the benefits of serious engagement in leisure activities: 1) the experience of psychological benefits, 2) the creation of social support, and 3) the enhancement of physical health. These themes indicate that, through serious involvement in certain physical activities, participants gain various health benefits, which may contribute to successful aging

Non-human primate model of amyotrophic lateral sclerosis with cytoplasmic mislocalization of TDP-43

Amyotrophic lateral sclerosis is a fatal neurodegenerative disease characterized by progressive motoneuron loss. Redistribution of transactive response deoxyribonucleic acid-binding protein 43 from the nucleus to the cytoplasm and the presence of cystatin C-positive Bunina bodies are considered pathological hallmarks of amyotrophic lateral sclerosis, but their significance has not been fully elucidated. Since all reported rodent transgenic models using wild-type transactive response deoxyribonucleic acid-binding protein 43 failed to recapitulate these features, we expected a species difference and aimed to make a non-human primate model of amyotrophic lateral sclerosis. We overexpressed wild-type human transactive response deoxyribonucleic acid-binding protein 43 in spinal cords of cynomolgus monkeys and rats by injecting adeno-associated virus vector into the cervical cord, and examined the phenotype using behavioural, electrophysiological, neuropathological and biochemical analyses. These monkeys developed progressive motor weakness and muscle atrophy with fasciculation in distal hand muscles first. They also showed regional cytoplasmic transactive response deoxyribonucleic acid-binding protein 43 mislocalization with loss of nuclear transactive response deoxyribonucleic acid-binding protein 43 staining in the lateral nuclear group of spinal cord innervating distal hand muscles and cystatin C-positive cytoplasmic aggregates, reminiscent of the spinal cord pathology of patients with amyotrophic lateral sclerosis. Transactive response deoxyribonucleic acid-binding protein 43 mislocalization was an early or presymptomatic event and was later associated with neuron loss. These findings suggest that the transactive response deoxyribonucleic acid-binding protein 43 mislocalization leads to α-motoneuron degeneration. Furthermore, truncation of transactive response deoxyribonucleic acid-binding protein 43 was not a prerequisite for motoneuronal degeneration, and phosphorylation of transactive response deoxyribonucleic acid-binding protein 43 occurred after degeneration had begun. In contrast, similarly prepared rat models expressed transactive response deoxyribonucleic acid-binding protein 43 only in the nucleus of motoneurons. There is thus a species difference in transactive response deoxyribonucleic acid-binding protein 43 pathology, and our monkey model recapitulates amyotrophic lateral sclerosis pathology to a greater extent than rodent models, providing a valuable tool for studying the pathogenesis of sporadic amyotrophic lateral sclerosis

The clinical benefits of immune checkpoint inhibitor for thymic carcinomas ∼experience of single public hospital in Japan∼

Thymic carcinomas is rare and highly aggressive carcinoma. Most patients with them are diagnosed as being at surgically unresectable stages due to it. There are several reports which showed the effect of chemotherapy, however, it is controversial. Recently, immune checkpoint inhibitors have changed conventional chemotherapy due to their effect against various types of cancers. We administered nivolumab, anti-Programmed Cell Death (PD)-1 antibody, to four patients with unresectable thymic carcinomas who had previously undergone conventional chemotherapy. A histopathology on tumors from these patients revealed the presence of squamous cell carcinoma and PD-L1 high expression. After treatment with nivolumab, it seemed to be beneficial to all patients; The best clinical responses of 3 patients were partial response and that of the other one was stable disease. None of them experienced severe immune-related adverse events. Our results suggest the potential benefits of using these inhibitors to treat thymic carcinomas in real world clinical setting as is the cases in recent clinical trials for the evaluation of immune checkpoint inhibitors for the treatment of thymic carcinoma
