Bacteria Endocarditis Caused by in a Juvenile, Immunosuppressed Pig () following Partial Heart Transplantation.

Domestic swine () are important translational models for cardiovascular transplant studies. This can be attributed to the anatomic and physiologic similarities of their cardiovascular system to humans. Transplant studies frequently employ clinically relevant immunosuppression regimens to prevent organ rejection postoperatively.

The impact of heart valve and partial heart transplant models on the development of banking methods for tissues and organs: A concise review.

Cryopreserved human heart valves fill a crucial role in the treatment for congenital cardiac anomalies, since the use of alternative mechanical and xenogeneic tissue valves have historically been limited in babies. Heart valve models have been used since 1998 to better understand the impact of cryopreservation variables on the heart valve tissue components with the ultimate goals of improving cryopreserved tissue outcomes and potentially extrapolating results with tissues to organs. Cryopreservation traditionally relies on conventional freezing, employing cryoprotective agents, and slow cooling to sub-zero centigrade temperatures; but it is plagued by the formation of ice crystals and cell damage upon thawing.

Vitamin D is associated with improved survival in early-stage non-small cell lung cancer patients.

Vitamin D may inhibit the development and progression of a wide spectrum of cancers. We investigated the associations of surgery season and vitamin D intake with recurrence-free survival (RFS) and overall survival in 456 early-stage non-small cell lung cancer patients. The data were analyzed using log-rank test and Cox proportional hazards models.

Polymorphisms in ERCC1 and grade 3 or 4 toxicity in non-small cell lung cancer patients.

Purpose: ERCC1 is a lead enzyme in the nucleotide excision repair pathway of DNA repair. Polymorphisms have been identified in the ERCC1 gene, the C8092A and codon 118 polymorphisms, which may lead to an altered capacity to regenerate damaged normal tissue and greater treatment-related toxicity.

Experimental Design: Using logistic regression models, we evaluated the ERCC1 C8092A and codon 118 polymorphisms and their association with the occurrence of grade 3 or 4 toxicity in 214 stage III and IV non-small cell lung cancer patients treated first line with platinum-based chemotherapy.

Genetic susceptibility to tobacco-related cancer.

Although cigarette smoking is the dominant risk factor for several epithelial cancers, only a small fraction of individuals with tobacco exposure develop cancer. The underlying hypothesis is that genetic factors may render certain smokers more susceptible to cancer than others. Genetic alterations in critical regulatory pathways may predispose cells to carcinogenesis.
