THRA Knockout Cell Lysate

Osteonecrosis of the femoral head is a severely disabling complication of steroid immunosuppression in renal transplant patients. The increased number of patients undergoing transplantation has increased the number of transplant recipients undergoing total hip replacement arthroplasty (THRA). In this study, we retrospectively assessed patients who underwent THRA from May 2004 to February 2014, and evaluated their demographic and clinical characteristics, the results of peri-operative laboratory tests, the amounts of fluids transfused during surgery, and anesthesia time. Our results found that post-operative acute kidney injury (AKI) was significantly associated with transplantation, and transplantation was an independent factor predictive of post-operative AKI, so transplant recipients are at risk for AKI following THRA. Total hip replacement is a safe and effective treatment for transplant recipients and, in view of their limited life expectancy, should be considered at an early stage in their treatment.

The mutation of Clostridium acetobutylicum mutant AA2, defective in the formation of acetone and butanol, was shown to be caused by a single insertion of Tn916 close to the structural gene thrA, encoding the tRNA(ACG)Thr. The DNA region containing the thrA gene was cloned and sequenced. Start and end points of the transcript were determined by primer extension and S1-mapping analysis. The results obtained were identical to predictions derived from the DNA sequence by various RNA-analysing computer programs. The rarely used ACG codon seems to be confined to genes expressed at the end of the exponential growth phase or involved in uptake or turnover of minor C or N substrates. Evolutionary aspects of this codon selection and a possible translational regulation mechanism are discussed.
