    Ultrastructure changes associated with brain death in the human donor heart (1996)

    Notes: Abstract Electromicroscopic examinations were carried out on 30 myocardial biopsies taken from 22 human donor hearts immediately after excision (prestorage) or immediately before transplantation (post-storage). All electron micrographs were independently examined by two morphologists. Eleven structures were examined in each micrograph, and each structure was scored according to the degree of injury. A good interobserver correlation was obtained in 84 % of the structures scored. In the prestorage left ventricular biopsies (n = 11), approximately 20 %–25 % showed moderate to severe ultrastructural injury. The ultrastructural injury observed in the poststorage left ventricular biopsies (n = 15) was no different from that in the prestorage group, particularly injury to the sarcomere and mitochondria. A similar degree and pattern of injury was seen in the right ventricle (n = 4). There was no evidence that an ischemic storage period of less than 6 h increased the degree of injury seen. However, there was a higher incidence of moderate to severe injury in those hearts excised from donors initially dependent on high inotropic support.

    Factors affecting graft excursion patterns in endoscopic anterior cruciate ligament reconstruction (1998)

    Notes: Abstract The effect of femoral guide rotation in endoscopic anterior cruciate ligament (ACL) reconstruction is reviewed based on a previous report. The effect of varied offsets of the femoral guide (5.5 and 7.0 mm) are described. This is one of the few isometry studies to evaluate the knee through a practically full range of motion (0°–120°). A 7-mm offset guide rotated to the 12 : 00 position yields the best single fiber and graft excursion patterns (P 〈 0.05). A 5.5-mm offset guide yields inferior single fiber and graft excursion patterns. Single fiber and graft isometry are similar but not identical in endoscopic ACL reconstruction. Centering the single fiber in the tibial tunnel has little effect on isometry patterns, demonstrating that the more posterior tibial positions needed for endoscopic reconstruction are acceptable from an isometry standpoint.

    Biodegradation of phenol using the self-cycling fermentation (SCF) process (1996)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 51 (1996), S. 112-119

    Notes: Self-cycling fermentation (SCF) in a stirred tank reactor was applied to the biodegradation of phenol by Pseudomonas putida. The technique resulted in stable and repeatable performance. Complete substrate consumption was achieved under all operating conditions investigated. SCF resulted in substrate utilization rates as high as 14.5 kg of phenol per cubic meter of fermentor volume per day of fermentation, higher than those that have been reported for batch, CSTR, and packed column fermentors. A mathematical model of the self-cycling fermentation process was expanded to include inhibitory substrate-microorganism combinations, and was shown to provide a good fit to both end-of-cycle and intracycle experimental data. © 1996 John Wiley & Sons, Inc.

    Mathematical model of self-cycling fermentation (1995)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: This article presents a mathematical model for biomass, limiting substrate, and dissolved oxygen concentrations during stable operation of self-cycling fermentation (SCF). Laboratory experiments using the bacterium Acinetobacter calcoaceticus RAG-1 and ethanol as the limiting substrate were performed to validate the model. A computer simulation developed from the model successfully matched experimental SCF intracycle trends and end-of-cycle results and, most importantly, settled into an unimposed periodicity characteristic of stable SCF operation. © 1995 John Wiley & Sons, Inc.
