Donor heart preservation for heart transplantation
… few years; the former because of the falling donor supply and the latter, in part, because of the use of less suitable donors in an effort to offset the problem of supply. Much attention has been focused on the drama of the surgery and the intricacies of immunological manipulation whilst …

Cypriot Donor Portraiture: Constructing the Ideal Family
This study focuses primarily on donor portraits of families found in Cypriot wall paintings and icons created during the Lusignan and Venetian periods. Although donor portraiture is a mode of expression that dates to antiquity, in the medieval period an increasingly prosperous upper middle class …

Exogenous donor-derived hepatogenesis in chimeric hosts
… development and the potential for generating donor-derived organs in chimeric hosts. In this dissertation, we begin with a comprehensive review of the literature (Chapter I) regarding histology and anatomy of liver, cardinal functions of the liver, followed by an overview of the current …

Dynamic combinatorial synthesis of donor-acceptor catenanes
… 2 describes the discovery of a new generation of donor-acceptor [2]catenanes in aqueous dynamic combinatorial systems. The assembly of these [2]catenanes is promoted by a high salt concentration (1 M NaNO3), which raises the ionic strength and encourages hydrophobic association. More importantly, …

Strategies to improve artificial insemination by donor
Artificial insemination with donor sperm is a widely accepted form of treatment for severe male factor infertility. The introduction of quarantined, cryopreserved semen and the associated reduction in cycle fecundity when compared to fresh semen necessitated the development of strategies to improve …

A review of living donor liver transplantation: why is regeneration more rapid in the recipient compared to the donor?
Living donor liver transplantation (LDLT) is now well established and performed on a routine basis in many major centres around the world. LDLT is feasible because of the capacity of both the remnant donor liver and the transplanted partial liver to undergo liver regeneration. However it has been …

Der EPR-spektroskopisch ermittelte D-Parameter von Cyclopentan-1,3-diyl-Triplettdiradikalen als Sonde zur Bestimmung von elektronischen Effekten in Propargyl- und Heteropropargylradikalen und geminal substituierten Donor/Donor- und Akzeptor/Donor-Allylradikalen
In der vorliegenden Arbeit wurde die Spindelokalisation im Propargylradikal im Vergleich zu den Heteropropargylradikalen untersucht, sowie die elektronischen Einflüsse, welche geminal gebundenen Substituenten auf die Spinverteilung in Allylradikalen verursachen bestimmt. Die Spindichte wurde mit …
