Ex vivo lung perfusion (EVLP) is used to evaluate donor lungs prior to lung transplantation. Development of pulmonary edema during EVLP is generally thought to represent inflammatory breakdown of the air-fluid barrier and these lungs are declined for transplant. We present the case of a donor lung that underwent stapled wedge resection during cold storage for air leak and the subsequent development of profound (∼650 mL) pulmonary edema around the staple line during EVLP.

The majority of nucleated somatic cells can be reprogrammed to induced pluripotent stem cells (iPSCs). The process of reprogramming involves epigenetic remodelling to turn on pluripotency-associated genes and turn off lineage-specific genes. Some evidence shows that iPSCs retain epigenetic marks of their cell of origin and this "epigenetic memory" influences their differentiation potential, with a preference towards their cell of origin.

When decellularizing kidneys, it is important to maintain the integrity of the acellular extracellular matrix (ECM), including associated adhesion proteins and growth factors that allow recellularized cells to adhere and migrate according to ECM specificity. Kidney decellularization requires the ionic detergent sodium dodecyl sulfate (SDS); however, this results in a loss of ECM proteins important for cell adherence, migration, and growth, particularly glycosaminoglycan (GAG)-associated proteins. Here, we demonstrate that using submicellar concentrations of SDS results in a greater retention of structural proteins, GAGs, growth factors, and cytokines.

The clinical application of induced pluripotent stem cells (iPSC) needs to balance the use of an autologous source that would be a perfect match for the patient against any safety or efficacy issues that might arise with using cells from an older patient or donor. Drs. Takahashi and Yamanaka and the Office of Cellular and Tissue-based Products (PMDA), Japan, have had concerns over the existence of accumulated DNA mutations in the cells of older donors and the possibility of long-term negative effects.

A 78-year-old female underwent a right pneumonectomy for a neuroendocrine tumour. In the early postoperative phase, she developed a paralytic ileus and went on to develop breathlessness and orthostatic desaturation, which characterizes platypnoea-orthodeoxia. She was found to have an intra-atrial shunt on bubble echo, with equal atrial pressures.

Decellularization is the process by which resident cells are lysed and cellular debris is removed from the tissue, leaving behind the extracellular matrix scaffold. The extracellular matrix scaffold can be used for three-dimensional culturing of cells. Here we describe methods of decellularizing whole and thick sections of mouse kidneys using a 0.

Chronic and nonhealing wounds are constant health issues facing patients with type 2 diabetes. As the incidence of type 2 diabetes mellitus (T2DM) increases, the incidence of chronic wounds and amputations will rise. T2DM is associated with peripheral arterial occlusive disease, which leads to the development of nonhealing skin ulcers after minor trauma.

The development of strategies for tissue regeneration and bio-artificial organ development is based on our understanding of embryogenesis. Differentiation protocols attempt to recapitulate the signaling modalities of gastrulation and organogenesis, coupled with cell selection regimens to isolate the cells of choice. This strategy is impeded by the lack of optimal in vitro culture systems since traditional culture systems do not allow for the three-dimensional interaction between cells and the extracellular matrix.

Objectives: To characterize comorbidities, health-related quality-of-life (HRQoL), productivity, and healthcare resource use in adults with atopic dermatitis (AD) relative to those without AD, and to evaluate the impact of patient-reported AD severity on these outcomes.

Methods: Data were from the 2013 National Health and Wellness Survey (NHWS), which collected self-reported information on demographics, comorbidities, HRQoL (SF-36v2 Health Survey), productivity (Work Productivity and Impairment questionnaire [WPAI]), and healthcare utilization, which were weighted to the US general population. The AD cohort consisted of subjects who reported that they experienced AD within the past 12 months (n = 428), and the non-AD cohort included all subjects who did not report experiencing AD (n = 74,572); 366 AD subjects self-reported mild (n = 182) or moderate/severe (n = 184) disease.

Peripheral vascular disease affects ~20 % of the population over 50 years of age and is a complication of type 2 diabetes. Cell therapy studies revealed that cells from older or diabetic donors have a reduced capacity to induce tissue repair compared to healthy and younger cells. This fact greatly impedes the use of autologous cells for treatment.

Human hematopoietic stem cell engraftment has been studied extensively using xenograft transplant models with immunocompromised mice. It is standard practice to incorporate mouse models, such as the limiting dilution assay, to accurately assess the number of repopulating stem cells in bone marrow or umbilical cord blood collections or to confirm the long-term repopulating ability of cultured hematopoietic stem cells. In a previous study using a standard NOD/SCID mouse model to assess human hematopoietic stem cell engraftment we observed that all human cells had mouse MHC class I protein on their surface, suggesting that this is a mechanism adopted by the cells to evade host immune surveillance.

The present study examined the moderating role of social support and challenging behaviour on the stress-physical health relationship in parents caring for children with intellectual disabilities. Parents of children with intellectual disabilities (n = 70) reported more physical health problems compared to control parents (n = 45) and were more likely to visit their general practitioner. Furthermore, challenging behaviours, but not social support, moderated this association: parents of children with intellectual disabilities reported poorer physical health when both challenging behaviours and stress were perceived to be high.
