The New Old Age Blog: Who Should Receive Organ Transplants?

A graying population and revised policies determining who gets priority for donated organs have led to a rising proportion of older adults receiving transplants.

In this study the effect of NMP perfusion fluid on survival, metabolism and function of thawed cryopreserved human (h)MSC and porcine (p)MSC in suspension conditions was studied. Suspension conditions reduced the viability of pMSC by 40% in both perfusion fluid and culture medium. Viability of hMSC was reduced by suspension conditions by 15% in perfusion fluid, whilst no differences were found in survival in culture medium. Under adherent conditions, survival of the cells was not affected by perfusion fluid. The perfusion fluid did not affect survival of fresh MSC in suspension compared to the control culture medium. The f...

One of the most promising strategies to increase organ donation is the use of organs from donors with Hepatitis C (HCV). We evaluated the safety of transplanting NAT+HCV donors into non-infected lung recipients.

Heart donation after circulatory death (DCD) has significantly improved organ utilisation with promising early outcomes. To date, adult DCD heart programmes have relied largely on ex-situ heart perfusion during transport of the donor organs even after normothermic regional perfusion (NRP) in the donor where the heart is formally assessed after circulatory arrest. In this pre-clinical porcine study we compare the use of cold storage as an alternative to ex-situ heart perfusion following NRP.

Evaluation of a potential lung graft in an ex-vivo lung perfusion (EVLP) system has gained an increased use among transplantation centers. Current standard of organ assessment before transplantation with machine perfusion are performed with normothermic temperature but sub-normothermic setting is under clinical use among several solid organs. Our aim was to investigate the impact of sub-normothermic EVLP from donation after circulatory death donor lungs in a rat model.

This article reviews the organ allocation philosophy focusing on the case of lung transplantations in Brazil.RESUMO A filosofia da aloca ção de órgãos é resultado de duas vertentes aparentemente inconciliáveis: utilitarismo e justiça distributiva. O processo de doação e transplante de órgãos no Brasil revela grandes desigualdades entre regiões e unidades da federação, desde a captação de órgãos até o implante dos ó rgãos. Nesse contexto, o transplante de pulmão é r...

In this study, scientists screened cells from old animals to identify any RBPs that change upon aging. The screening showed that one particular protein, Pumilio2 (PUM2), was highly induced in old animals. PUM2 binds mRNA molecules containing specific recognition sites. Upon its binding, PUM2 represses the translation of the target mRNAs into proteins. Using a systems genetics approach, the researchers then identified a new mRNA target that PUM2 binds. The mRNA encodes for a protein called Mitochondrial Fission Factor (MFF), and is a pivotal regulator of mitochondrial fission - a process by which mitochondria break u...

This study suggests that advantages and disadvantages vary by environment and diet, however, which might explain why evolution has selected for multiple haplogroups rather than one dominant haplogroup. This is all interesting, but none of it stops the research community from engineering a globally better-than-natural human mitochondrial genome, and then copying it into the cell nucleus as a backup to prevent the well-known contribution of mitochondrial DNA damage to aging. Further, nothing stops us from keeping the haplogroups we have and rendering the effects of variants small and irrelevant through the development...

Human body is intertwined collection of lives of Individual organs.We believe death occurs when brain dies , respiration stops and circulation ceases . Curiously ,when life ends , these organs  don’t die as a single unit . These three events can happen in any of the six possible permutations.Each organ takes different times to die after loss of life.It is like a crashed computer , where the mother board /RAM memory may be transferred to another and be functional . Out of these three , heart function appears to be supreme as it can function without the need of brain (Science of brain-death) and keep the body...
