    Notes: Recent advances in techniques of coronary artery exposure and myocardial stabilization in off-pump myocardial revascularization have provided cardiac surgeons with a wide variety of new devices and techniques. Until recently, the main obstacle to performing complete myocardial revascularization without using cardiopulmonary bypass (CPB) has been the technical difficulties of exposing and stabilizing coronary targets, especially those located on the lateral and inferior wall of the heart. The extraordinary cardiac tolerance to nonconstrictive anterior elevation and lateral displacement, however, has allowed the development of new strategies of coronary exposure. These advances, in combination with the development of new techniques of mechanical myocardial stabilization, have impacted on the feasibility and safety with which coronary anastomoses on the beating heart can be constructed. The aim of this article is to describe the technical aspects involved in off-pump coronary revascularization, focusing primarily on the most recent strategies of cardiac elevation and coronary exposure, the various techniques of myocardial stabilization, and some of the technical details of constructing distal anastomoses on the beating heart.

    A Globin Fragment, LVV-Hemorphin-7, Induces [3H]Thymidine Incorporation in a Neuronal Cell Line via the AT4 Receptor (1999)

    Notes: Abstract: The AT4 receptor was characterized initially as a specific binding site for angiotensin IV, a C-terminal fragment of the vasoactive peptide angiotensin II. Recently, we found that LVV-hemorphin-7, a fragment of β globin, is an abundant peptide in the brain and binds to the AT4 receptor with high affinity and specificity. In the neuroblastoma/glioma hybrid cell line, NG108-15, LVV-hemorphin-7 and angiotensin IV competed for 125I-angiotensin IV binding in a biphasic fashion with IC50 values of 1.2 × 10-10 and 1.1 × 10-9M for the high-affinity site, respectively, and 6.7 × 10-8 and 1.5 × 10-8M for the low-affinity site, respectively. Both peptides were internalized rapidly by the cells. However, LVV-hemorphin-7, but not angiotensin IV, elicited a 1.8-fold increase in DNA synthesis in a dose-dependent manner. Furthermore, co-incubation of the cells with an excess of angiotensin IV (10-6M) inhibited LVV-hemorphin-7-stimulated DNA synthesis. Therefore, whereas LVV-hemorphin-7 and angiotensin IV were capable of binding to the AT4 receptor, only LVV-hemorphin-7 elicited [3H]thymidine incorporation in NG108-15 cells. In contrast, angiotensin IV behaved as an antagonist. The current finding suggests that LVV-hemorphin-7 is a functional peptide in the central nervous system and in view of its abundance in neural tissue, compared with angiotensin IV, may be of significant physiological importance.

    Raman analysis of short-range clustering in laser-deposited CdSxTe1−x films (1998)

    Notes: Raman line shapes of the longitudinal optical phonon have been analyzed for the pseudobinary alloy system CdSxTe1−x over the full alloy range. The polycrystalline thin films were grown by pulsed laser deposition at, typically, 370 °C including films with x values throughout the miscibility gap (0.06〈x〈0.97). Peak shift, broadening, and asymmetry arising from spatial correlation effects yield details of the microstructural clustering. The dependence of phonon coherence length on the x value cannot be explained simply from a random occupancy of the anion sublattice. We employed a linear chain model with site probabilities modified by the Warren–Cowley short-range order parameter to infer coherence lengths versus x. The data are best fit with a short-range order parameter of 0.73 at x=1/2. © 1998 American Institute of Physics.

    Can winners be losers? The case of the Deming prize for quality and performance among large Japanese manufacturing firms (1999)

    Topics: Economics
    Notes: Much literature suggests a positive relationship between winning a quality award and subsequent firm performance. However, for the vast majority of the large Japanese manufacturing firms that have won the Deming Prize results in this study indicate a negative association. Results also show that for a minority of these firms there does appear to be a positive relationship between winning and subsequent performance. Two theories, the danger of simplicity and the winner's curse, are utilized to explain these results. Firms that compete for quality awards have a significant risk of putting undue pressure on organizational resources or focusing too narrowly on winning and neglecting other aspects of their business, thereby leading to performance shortfalls. Significant experience in TQM/TQC prior to competing for a quality award may moderate these risks. For managers, there should be serious consideration as to whether their companies should compete for a quality award in the hope of improving performance. Instead, they may want to ask if there are any alternative methods for designing and implementing improvements in quality control.

    Identification and characterisation of cultivar-specific 22-kDa heat shock proteins from mitochondria of Pisum sativum (1998)
    Copenhagen : Munksgaard International Publishers
    Physiologia plantarum 103 (1998), S. 0

    Notes: Pea plants (Pisum sativum L. cv. Feltham First) exposed to a heat stress of 37°C for 6 h accumulated two low molecular weight (LMW) heat shock proteins (HSPs) of molecular mass 22 kDa. The two LMW HSPs were associated with purified mitochondria. N-terminal amino acid sequencing analysis indicates that the more basic of these proteins is a novel protein. The response of other cultivars of P. sativum to heat shock revealed that up to three 22-kDa HSPs were expressed in a cultivar-specific manner. Evidence presented suggests that the different 22-kDa HSPs arise as a result of there being multiple 22-kDa HSP genes. The expression of the most basic novel HSP was studied in the Feltham First cultivar using two dimensional SDS-PAGE. Treatment of intact plants with chloramphenicol and cycloheximide prior to heat stress treatment indicated that the LMW HSPs were nuclear encoded and de novo synthesised. The response to heat shock was rapid with protein expression detected within 45 min and the protein remained in excess of 6 days following removal of the stress. The protein accumulated to very high levels with maximal expression being 2% of the total mitochondrial protein. The results are discussed in relation to the likely role of LMW HSPs in thermotolerance.

    Chemistry of the Aqueous Phase of Ordinary Portland Cement Pastes at Early Reaction Times (1998)

    Notes: The chemistry of the aqueous phase of ordinary portland cement paste at early ages (〈2 h) has been analyzed in terms of the concentrations of the elemental components in the pore fluid. The concentrations of calcium, sulfur, aluminum, and silicon are rationalized by plotting the data on “phase diagrams.” To simplify the analysis, the portland cement system is described using two subsystems: (i) CaO-Al2O3-CaSO4-H2O, modified by the presence of sodium and potassium, and (ii) CaO-SiO2-H2O. During the first 10 min of hydration, the calcium, sulfur, and aluminum concentrations all decrease, roughly in proportion, which suggests a precipitation process, a conversion of calcium sulfate hemihydrate to gypsum, and the initial formation of ettringite. The CaO-Al2O3-CaSO4-H2O subsystem seems to move from a phase assemblage of gypsum, Al2O3·3H2O, and ettringite to an assemblage of gypsum, calcium hydroxide, and ettringite during the first 15-30 min after the water and the cement are mixed. The silicate equilibrium is approached more slowly. The intensity of mixing has relatively little effect on the concentrations beyond the first few minutes.

    Notes: Abstract A respirometric system was used to analyze the biodegradation of high molecular weight (120,000 to 200,000 g mol−1) polylactic acid (PLA) plastic films in soil under laboratory conditions. The respirometric system consisted of air-conditioning pretraps, a soil reactor, and a carbon dioxide (CO2) posttrap. A 200-g homogeneous soil mixture of all-purpose potting soil : manure soil : sand [1 : 1 : 1 (w/w)] and 1.5 g of PLA plastic films in 1 × 1-cm2 squares was added to each bottle. The respirometers were placed in a 28, 40, or 55°C water bath for 182 days. Treatments (three replicates) included native corn starch (positive control), polyethylene (Glad Cling Wrap; negative control), and three PLA films: Ca-I (Cargill Dow Polymers LLC, monolayer), GII (Cargill Dow Polymers LLC, Generation II), and Ch-I (Chronopol; monolayer). The degree of polymer mineralization was indicated by the cumulative CO2 liberated from each respirometer. The initial average mineralization rate and total percentage mineralized of the PLA plastic films at 28, 40, and 55°C was 24.3, 41.5, and 76.9 mg/day with a 27, 45, and 70% carbon loss, respectively. No decrease in soil pH was observed after 182 days of mineralization. Hence, increase in soil temperature drastically enhanced the biodegradation of PLA plastic films in soil under laboratory conditions (P 〈 0.0001).
