Burnt and Blossoming: Material Mysticism in Trilogy and Four Quartets

This paper brings two WWII poems into dialogue: H.D.'s Trilogy and Eliot's Four Quartets. Both poems express a creative response to the destruction of war. My reading of Trilogy suggests a material mysticism in which vision and renewal are situated within the natural world, rituals and bodily experience. Bringing this understanding of mysticism to bear on Four Quartets reveals tension between transcendence and materiality. For Eliot, redemption comes through time and location, while for H.D., redemption lies within material particularity. Four Quartets oscillates between an apophatic discourse that seeks to transcend desire and history and an emphasis on material particularities

Acquired immunologic tolerance: with particular reference to transplantation

The first unequivocally successful bone marrow cell transplantation in humans was recorded in 1968 by the University of Minnesota team of Robert A. Good (Gatti et al. Lancet 2: 1366–1369, 1968). This achievement was a direct extension of mouse models of acquired immunologic tolerance that were established 15 years earlier. In contrast, organ (i.e. kidney) transplantation was accomplished precociously in humans (in 1959) before demonstrating its feasibility in any experimental model and in the absence of a defensible immunologic rationale. Due to the striking differences between the outcomes with the two kinds of procedure, the mechanisms of organ engraftment were long thought to differ from the leukocyte chimerism-associated ones of bone marrow transplantation. This and other concepts of alloengraftment and acquired tolerance have changed over time. Current concepts and their clinical implications can be understood and discussed best from the perspective provided by the life and times of Bob Good

Epithelial and hematopoietic cell chimerism in intestinal allografts

In intestinal transplantation recipient lymphocytes infiltrate the allograft soon after reperfusion. Recently, it has been demonstrated that long-surviving small bowel transplants bear enterocytes of recipient origin. We investigated whether epithelial cells (enterocytes) persisted in long-term allografts based on studies of biopsies. The biopsies of four male intestinal transplant recipients of female grafts with a previous graft biopsy positive for recipient enterocytes were examined at least 6 months after previous positive assessment. Using the FISH technique, we searched for Y-chromosome-positive enterocytes in the female allograft. Recipient male enterocytes were identified in all biopsies at low percentages ranging from 0.18 to 0.26. The lymphocytes within the graft were of both recipient (male) and donor (female) origin. The four types of cells—enterocytes and lymphocytes of recipient and donor origin—coexist in long-term graft biopsies

Citrulline Evaluation in Bowel Transplantation

The purpose of this study was to evaluate the correlation of plasma citrulline and rejection episodes in intestinal transplantation. From January 2007 until present, we performed citrulline assays on our small bowel patients. We investigated the correlation of these assays with the rejection status of the patients. The rejection status of the graft was defined based on graft biopsies. Of 5195 citrulline samples, average serum citrulline levels decreased significantly when the patients presented a rejection episode. We found the following: no rejection, 17.38 μm/L; mild rejection, 13.05 μm/L; moderate rejection, 7.98 μm/L; and severe rejection, 6.05 μm/L. Our current emphasis is to determine the predictive power of citrulline with other biomarkers versus as a separate and isolated measurement. In our study, citrulline levels correlated significantly with the rejection status of the graft. Serial follow-up of the patients using this assay may alert us to the possibility of increased alloreactivity and rejection episodes
