The interrelation between the rates of the innervated recipient heart and the denervated donor heart at rest, on standing, and during the different phases of maximal exercise was studied in nine patients 1-6 months after heterotopic cardiac transplantation. The resting heart rate was significantly higher in the donor heart compared with the recipient heart. Eight of the nine recipient hearts an...

Competing phylogenetic models have been proposed to explain the success of species introduced other communities. Here, we present a study predicting establishment birds Florida, Hawaii and New Zealand using several alternative models, considering species' relatedness source- recipient-range taxa, propagule pressure traits. We find consistent support for predictive ability source-region structur...

Background Although ovarian tissue cryopreservation and transplantation is used for fertility preservation in patient undergoing cytotoxic treatments but obtaining good quality oocyte is still a debate. Xenotransplantation has been introduced as a reliable technique for better understanding of the transplantation conditions, but to achieve healthy embryos, the quality of obtained oocytes need t...

Legionella londiniensis has been isolated from aqueous environments. However, to our knowledge, this organism has never been isolated from clinical specimens. A case of Legionnaires' disease in a hematopoietic stem cell transplant recipient caused by this organism is described, which confirms that L. londiniensis can be an opportunistic pathogen.

Performing a greater number of free flap procedures inevitably results in an increase in the number of cases that experience free flap failure. In cases that require a second free flap after the failure of the first, recipient vessel selection becomes difficult. Furthermore, recipient vessel selection can be complicated if the vessel is deep in the recipient site, or if there is an increased ri...

Malignancy has become one of the three major causes of death after transplantation in the past decade and is thus increasingly important in all organ transplant programs. Death from cardiovascular disease and infection are both decreasing in frequency from a combination of screening, prophylaxis, aggressive risk factor management, and interventional therapies. Cancer, on the other hand, is poor...

Isolated kidneys taken from normotensive Wistar-Kyoto rats were cross-perfused extracorporeally by normotensive strain-matched donor rats. The extracorporeal perfusion circuit was arranged so that the perfusion pressure to the normotensive recipient kidney could be varied from 90 to 200 mm Hg without any change in total flow through this circuit. This setup avoided hemodynamic or mechanical int...
