PURPOSE: To investigate the contents of green- and blue-sensitive cone photoreceptors in laminated rabbit retinal transplants.METHODS: Eleven rabbits each received a sheet of embryonic neuroretina into the subretinal space in one eye. Vitrectomy was used in the procedure and properly polarized flat transplants were placed on the host pigment epithelium. After 17-309 days the transplants were exami
Embryonic full-thickness rabbit neuroretinal sheets were transplanted to the subretinal space of adult hosts. This was accomplished by using a new transplantation technique involving vitrectomy and retinotomy. The grafts were followed from 10 to 306 days after surgery and were then examined by different histological techniques. In the light microscope, the transplants were seen to develop the norm
BACKGROUND: The study was carried out to evaluate the expression of major histocompatibility complex (MHC) molecules in retinal transplants with different tissue integrity.METHODS: Twelve adult rabbits received an allogeneic subretinal neuroretinal transplant, in the form of either fragmented embryonic cells or a complete full-thickness embryonic retina. A controlled transvitreal approach was used
PURPOSE: To establish neuronal connections in the rod and cone pathway between laminated rabbit retinal transplants and the host retina.METHODS: Fourteen adult rabbits received a complete full-thickness embryonic transplant. After survival times of 3 to 10 months, the retinas were studied under light microscope and with immunohistochemistry. Antibodies against protein kinase C (PKC), parvalbumin,
PURPOSE: To examine immunohistochemical markers in straight, well-laminated retinal transplants with special attention paid to the interphotoreceptor matrix, the Müller cells and the ganglion cells as these three retinal components have been abnormal in transplants produced by previous methods.METHODS: Nine rabbits underwent subretinal transplantation of a complete full-thickness embryonic neurore
PURPOSE: To establish the light and electron microscopic morphology of long-term full-thickness embryonic rabbit retinal transplants, with special attention paid to graft- host integration.METHODS: Eighteen rabbits received a complete embryonic neuroretina 19 days after conception. The transplants were positioned under the host retina, flat against the host retinal pigment epithelium with proper p
Adult and embryonic rabbit retinal sheets were transplanted into the subretinal space of adult rabbits. The transplants were either full-thickness with intact layering, or gelatin embedded and vibratome sectioned with the inner retina removed. The full-thickness grafts were positioned subretinally by means of a glass capillary in which they were partially folded. The vibratome sectioned ones were
PURPOSE: To develop an improved surgical technique making full-thickness retinal transplant possible, thereby achieving a normal laminated transplant with minimal rosette formation.METHODS: A total of 23 rabbits underwent vitrectomy, retinotomy, and subsequent subretinal transplant of a complete embryonic neuroretina using a specially crafted glass cannula. Of the 23 animals, 15 received a prenata
This study delineates the permissible scope for compulsory mental health interventions under the Convention on the Rights of Persons with Disabilities (CRPD). It was initially triggered by two competing positions within the current debate over the future of coercive psychiatry; a practice that is still omnipresent among states worldwide. According to one position, defended by the CRPD Committee amThis study delineates the permissible scope for compulsory mental health interventions under the Convention on the Rights of Persons with Disabilities (CRPD).

The S-HELP Decision Support System was developed in a fp7 EU project for improving preparedness, response, and interoperability of health services and other main stakeholders involved in emergency situations (http://www.fp7-shelp.eu/project). We, the team of the University of Vienna, investigated emergency interventions/tasks performed by emergency responders (skills taxonomy) using emergency mate
This thesis delves into two ‘edge areas’ located in and around East Jerusalem. It attempts to unfold and analyze the dynamics in these edge areas, while investigating the agency of the people present there through their own perceptions and practices towards the land, the urbanization processes, the power circulation and the structural impositions. Squeezed by a settler-colonial domination that con
Families living with mental illness express needs of support and experiences of burden that may affect their own health detrimentally and hence also their ability to support the patient. Mindfulness-based interventions have shown beneficial health effects in both clinical and healthy populations. The aim of the current study was to explore the effectiveness and usability of a web-based mindfulness
