Dressler-de Winter sign: an independent ECG entity, or a mosaic in the palette of acute coronary syndromes
No full textDressler–de Winter sign: an independent ECG entity, or a mosaic in the palette of acute coronary syndromes. The author presents three different ECG manifestations of the Dressler–de Winter sign. The Dressler–de Winter sign and STEMI not only show temporal dynamicity, but the two ECG patterns can coexist in the same electrocardiograms. This observation strongly argues for a true ischemic etiology rather than being due to anatomical variations of the Purkinje fibers or lack of activation of sarcolemmal ATP-sensitive potassium (KATP) channels by ischemic ATP depletion, as was originally proposed
Marie Dressler, the Unlikeliest Star
No full textSHE WAS a good old girl. Yes, that\u27s what you think while reading author Betty Lee\u27s biography, Marie Dressler, The Unlikeliest Star. It\u27s a very satisfying book and it merits a careful reading. The prologue says what Marie Dressler was all about, really all about, and her story which follows is one of the most enjoyable I\u27ve ever read. It\u27s dispassionate, it\u27s non-judgmental, the author gives you time, date and place consistently, which isn\u27t easy, considering the profession Marie was in and the number of times she bought and sold properties when she became affluent, and even before she became affluent. In our day, Marie Dressler would have been called a \u27risk taker\u27. Her career was lived through five decades, at a time when there was constant opportunity for a great stage career, if you had the talent, skill, friends, luck and sheer perseverance to make a life in..
Predicting UHMWPE wear: decreasing wear rate following a change in sliding direction
No full textThe patient demographic for total joint replacement is becoming younger and more active leading to increased performance expectations [1]. To develop new products that meet these demands, computer simulations that predict wear are emerging as potential design tools [2]. The algorithms for these simulations typically assume a linear relationship between wear and sliding distance [3-5] and therefore do not account for the possibility of a variable wear rate along a path (Fig 1). In a previous study we demonstrated that the wear of crosslinked polyethylene did not depend on the sliding distance, rather on the number of crossing events (ie changes in direction) [6], implying that large portions of sliding did not contribute to the total wear. We were unable, however, to identify the transition from high wearing multidirectional sliding to the low wearing unidirectional sliding (Fig 1). The purpose of this study was to further investigate this transition by examining a broader range of sliding distances. We hypothesized that small increases in sliding distance after a direction change would produce additional cumulative wear while no additional wear would be produced at longer sliding distances sufficient to reestablish ‘unidirectional’ sliding

Euglossa avicula Dressler 1982
No full textEuglossa avicula Dressler, 1982 b Euglossa avicula is here reported for the first time outside the state of Espírito Santo. This species had only been recorded in the type locality (Conceição da Barra, northern Espírito Santo—Dressler 1982, Nemésio 2011 c) and at Reserva Natural Vale, in Linhares (northern Espírito Santo—Bonilla-Gómez 1999). I recorded this species at all sampled areas in the state of Espírito Santo and in five forest remnants in the state of Bahia (Fig. 3): (i) RPPN Veracel (Santa Cruz Cabrália), (ii) PN Pau Brasil (Porto Seguro), (iii) PN Monte Pascoal, (iv) PN Descobrimento, and (v) a non-protected forest fragment of ca. 300 ha in Itaramaju. The occurrence of this species in Santa Cruz Cabrália, the northernmost record of this species to date, extends its known geographic range in ca. 200 km northwards. The available data suggest this is the species with the shortest distributional range among the species of the Euglossa purpurea group occurring in the Atlantic Forest. Among the ca. 70 males collected in “Hileia Baiana”, around 70 % were attracted to vanillin. The remaining specimens were attracted to trans -methyl cinnamate, p -cresol acetate, cineole, skatole, p -tolyl acetate, β-ionone, dimethoxybenzene and mixtures (1: 1) p -tolyl acetate + trans -methyl cinnamate, and p -tolyl acetate + vanillin. Dressler (1982 b) had only recorded this species at cineole and vanillin baits, but it proved to be attracted to a very wide bouquet of scents.Published as part of Nemésio, André, 2012, Species of Euglossa Latreille, 1802 (Hymenoptera: Apidae: Euglossina) belonging to the purpurea species group occurring in eastern Brazil, with description of Euglossa monnei sp. n., pp. 35-52 in Zootaxa 3151 on pages 40-41, DOI: 10.5281/zenodo.21434
Predicting implant UHMWPE wear in-silico: A robust, adaptable computational-numerical framework for future theoretical models
No full textComputational methods for the pre-clinical wear prediction for devices such as hip, knee or spinal implants are valuable both to industry and academia. Archard’s wear model laid the basis for the first generation of theoretical wear estimation algorithms, and this has been adapted to account for the importance of multi-directional sliding. These second-generation cross-shear algorithms are useful, but they leave room for improvement.In this paper, we outline a generalised framework for a ‘third generation’ wear model. The essential feature of this proposed approach is that it removes the acausality and scale-independence of current second-generation algorithms. The methodology is presented in such a way that any existing second-generation model could be adapted using this framework. Using this approach, the predictive power against pin-on-disc and implant tests is shown to be improved; however, the model is still essentially a purely adhesive-abrasive wear predictor, accounting for only a limited number of factors as part of the tribological process. Further ongoing work is needed to expand and improve upon the current capabilities of in-silico UHMWPE wear prediction capabilities.<br/
