COST COMPARISONS FOR CARBON DIOXIDE AND MECHANICAL MULTI-TEMPERATURE REFRIGERATION SYSTEMS ON HIGHWAY TRAILERS

Liquid carbon dioxide refrigeration offers a simple, reliable alternative to mechanical transport refrigeration for food delivery trailers operated in an upper midwestern area that could be cost effective when the refrigerant's cost is $87 or less per ton. Operating and ownership costs were compared for both systems. Under the conditions of the study, a carbon dioxide system was more economical than a mechanical refrigeration system when the cost of the liquid carbon dioxide was$87 per ton or less. The study indicated that a fleet of at least ten carbon dioxide refrigerated units is needed to justify use of a storage tank that can accept a 20-ton delivery of liquid carbon dioxide

Cardiac regenerative potential of adipose tissue-derived stem cells (Review)

Myocyte loss due to ischemia/reperfusion injury leads to cardiac dysfunction and heart failure, and the concentration of current therapy is limited on preventing the progression. Recent interest has focused on transplantation of stem cells to differentiate and replenish the loss of myocytes. Adipose tissue represents an alternative and abundant source of adult stem cells with the ability to differentiate along multiple lineage pathways. Recent studies have demonstrated the potential of adipose tissue-derived stem cells for treatment of acute myocardial infarction. The aim of this review is to discuss the potential therapeutic benefits of adipose tissue-derived stem cells in improving cardiac function post-injury
