The human mitochondrial genome is very small and economically packed; the expression of the whole genome is essential for the maintenance of mitochondrial bioenergetic function. Mutation occurs at a much higher rate in the mitochondrial DNA (mtDNA) than in chromosomal DNA. Transient heteroplasmy of mtDNA occurs after a mutational event; the random pattern(More)
Deletions in mitochondrial DNA (mtDNA) accumulate with age in humans without overt mitochondriopathies, but relatively limited attention has been devoted to the measurement of the total number of mtDNA molecules per cell during ageing. We have developed a precise assay that determines mtDNA levels relative to nuclear DNA using a PCR-based procedure.(More)
UNLABELLED With ageing of the general population, increasing numbers of elderly patients are presenting for interventional cardiac treatment such as cardiac surgery, angioplasty and thrombolysis. However, the results of these interventions in the elderly are inferior to those in the young. A likely contributing factor is an age-related reduction in cellular(More)
A mucin preparation from a colonic adenocarcinoma was used to prepare monoclonal antibodies (MAbs) that reacted specifically either with normal adult small-intestine mucin antigen(s) (SIMA), or normal adult large-intestine mucin antigen(s) (LIMA). Both SIMA and LIMA show a unique oncofetal pattern of expression. Thus SIMA was expressed in early fetal(More)
With aging of the population, increasing numbers of elderly patients are presenting for cardiac surgery. However, the results in the elderly are inferior to those in the young. A likely contributing factor is an age-related reduction in cellular energy production in the myocardium during surgery, which is known to induce aerobic and ischemic stress. The(More)
Chemotherapy-induced peripheral neuropathy (CIPN) is a debilitating side effect resulting from neurotoxic chemotherapeutic agents. This study aimed to assess the efficacy and safety of an oral B group vitamin compared to placebo, in preventing the incidence of CIPN in cancer patients undergoing neurotoxic chemotherapy. A pilot, randomised,(More)
A host of compounds are retained in the body of uremic patients, as a consequence of progressive renal failure. Hundreds of compounds have been reported to be retention solutes and many have been proven to have adverse biological activity, and recognized as uremic toxins. The major mechanistic overview considered to contribute to uremic toxin overload(More)
