    Notes: Abstract Minimally invasive coronary artery bypass is defined as any maneuver or modification of conventional coronary bypass that decreases adverse effects. These adverse effects fall into three broad categories, which are access trauma, consequences of cardiopulmonary bypass, and aortic manipulation. In the minimally invasive direct coronary artery bypass (MIDCAB) approach, coronary revascularization is performed via a limited access incision, usually a left anterior thoracotomy, through which a left internal mammary artery is anastomosed under direct vision to the left anterior descending artery on a stabilized beating heart. Harvest of the left internal mammary artery can be performed with video assistance (two- or three-dimensional or under direct vision). A variety of offset chest wall retractors that allow internal mammary artery harvest under direct vision have simplified the procedure, and several mechanical stabilization devices (with or without suction) allow local wall immobilization for a target vessel anastomosis. Graft patency data from early series of stabilized MIDCAB procedures and published series of left internal mammary artery graft patency with conventional bypass grafting appear to be comparable. Current indications for MIDCAB include restenosis of the left anterior descending artery after catheter-based therapy and the necessity for target vessel revascularization in elderly high-risk patients with multivessel disease. Limitations of the MIDCAB procedure include mostly single vessel revascularization of the anterior aspect of the heart. (J Card Surg 1998;13:290–296)

    Comparison of Eye Motion in Wakefulness and REM Sleep (1985)

    Notes: Rapid eye movements (REMs) in sleep have been postulated to represent ocular activity directly related to the visual imagery of dreaming. In accord with this notion, there have been reports that the physiological characteristics of REMs are identical to those of waking saccades which occur in the absence of visual targets. Contradictory evidence is herein presented establishing that REMs are significantly slower than waking saccades of comparable amplitude, and that this slowdown is greater than can be attributed to either eye closure or to eye movements in total darkness. Furthermore, it is shown that in REM sleep, both small (5.5°) and large (11°) saccade-like movements generate essentially the same maximal force and have the same velocity for the major portion of their trajectories. In sleep, therefore, there is probably a central inhibition of the saccade-like REMs, especially of the large amplitude movements, thus leading to an uncoupling of the usual amplitude-velocity relationship observed in the waking state.

    Notes: We have observed progressive damage due to reabsorption of stimulated emission in optically pumped laser-quality GaInN–GaN multiple quantum wells. The degradation occurred on a time scale consistent with the lifetime of electrically pumped lasers incorporating the same active region, suggesting that the failure mechanism was in part catastrophic optical damage, and not just heating in the p contact and p cladding as is often assumed. © 1998 American Institute of Physics.

    Literature and Theory: Siegfried Kracauer's Law, Walter Benjamin's Allegory and G. K. Chesterton's The Innocence of Father Brown (1999)

    Notes: In this article I read Kracauer's Der Detektiv-Roman. Ein Philoso-phisches Fragment as a critical response to both Walter Benjamin's evaluation of allegory and to his intense messianism and the concomitant rejection of the theory and practice of law. Kracauer contrasts the detective not with a Benjaminian allegorical reader but with the priest. I shall follow up Kracauer's references to G.K. Chesterton's The Innocence of Father Brown and discuss the latter as the main narrative subtext for the theory advanced in Der Detektiv-Roman. Like Kracauer, Chesterton contrasts the detective as a representative of absolutized and instrumentalized reason with the priest as representative of critical intelligence and charitable action. In his critique of modernity Chesterton focuses on charity, whereas Kracauer evaluates Jewish law. The biblical background of such contrast between the glorification of an instrumen-talised rationality and a ceaseless questioning of the ethical validity of reason out of an awareness of human frailty unites these two differing criticisms of modern society. The intertextuality of Kracauer's Der Detektiv-Roman and Chesterton's The Innocence of Father Brown points to the reciprocity between law and charity.

    Die Blendung as a Negative Poetics: Positivism, Nihilism, Fascism (1999)

    Notes: In his representation of a fragmented society and his critique of the positivist scholar Peter Kien, Canetti develops a negative poetics: he shows what the poet should not be and what he should work against. This paves the way for a better understanding of Masse und Macht. Canetti's poetics in many respects resembles the image of the poet as advanced by his friend, the Oxford anthropologist Franz Baermann Steiner. Steiner did not separate his scholarly pursuits from social issues and his literary work. This connection between scholarship and a literary mode of writing constitutes the style and methodology of Masse und Macht and offers a striking contrast to Kien's positivism.

    Notes: Summary The genes SNQ and SFA confer hyperresistance to 4-NQO and FA when present on a multi-copy plasmid in yeast. Both are non-essential genes since transplacement of SNQ by a disrupted snq-0::LEU2 yielded stable and viable haploid integrants. Southern analysis revealed that SNQ and SFA are single-loci genes, and OFAGE analysis showed that they are located on chromosome XIII and IV, respectively. Northern blot analysis of SNQ and SFA revealed poly(A)+ RNA transcripts of 2 kb and 1.7 kb, respectively. Nuclease S 1 mapping showed SNQ to have a coding region of 1.6 kb and SFA, one of 1.3 kb. The 5′ coding regions were determined for both genes, while the 3′ end could only be determined for gene SNQ. Both genes do not appear to contain introns. The SFA locus was also mapped by transposon mutagenesis. Tn10-LUK integrants disrupted the SFA gene function at sites that were determined by subcloning to lie within the SFA transcription unit.

    Notes: Summary The hyperresistance to 4-nitroquinoline-N-oxide (4-NQO) and formaldehyde (FA) of yeast strains transformed with the multi-copy plasmids pAR172 and pAR184, respectively, is due to the two genes, SNQ and SFA, which are present on these plasmids. Restriction analysis revealed the maximal size of SFA as 2.7 kb and of SNQ as 2.2 kb, including transcription control elements. The presence of the smallest 2.7 kb subclone carrying SFA increased hyperresistance to formaldehyde fivefold over that of the original pAR184 isolate. No such increase in hyperresistance to 4-NQO was seen with the smaller subclones of the pAR172 isolate. Disruption of the SFA gene led to a threefold increase in sensitivity to FA as compared with the wild type. Expression of gene SNQ introduced on a multi-copy vector into haploid yeast mutants rad2, rad3, and snm1 did not complement these mutations that block excision repair.

    Notes: Summary We have isolated yeast gene SNM1 via complementation of sensitivity towards bi- and tri-functional alkylating agents in haploid and diploid yeast DNA repair-deficient snm1-1 mutants. Four independent clones of plasmid DNA containing the SNM1 locus were isolated after transformation with a YEp24-based yeast gene bank. Subcloned SNM1-containing DNA showed (i) complementation of the repair-deficiency phenotype caused by either one of the two different mutant alleles snm1-1 and snm1-2 ts; (ii) complementation in haploid and diploid yeast snm1-1 mutants by either single or multiple copies of the SNM1 locus; and (iii) that the SNM1 gene is at most 2.4 kb in size. Expression of SNM1 on the smallest subclone, however, was under the control of the GAL1 promotor. Gene size and direction of transcription was further verified by mutagenesis of SNM1 by Tn10-LUK transposon insertion. Five plasmids containing Tn10-LUK insertions at different sites of the SNM1-containing DNA were able to disrupt function of genomic SNM1 after gene transplacement. Correct integration of the disrupted SNM1::Tn10-LUK at the genomic site of SNM1 was verified via tetrad analysis of the sporulated diploid obtained after mating of the SNM1::Tn10-LUK transformant to a haploid strain containing the URA3 SNM1 wild-type alleles. The size of the poly(A)+ RNA transcript of the SNM1 gene is 1.1 kb as determined by Northern analysis.
