Hermann Minkowski’s Cologne Lecture, “Raum und Zeit”

2018

A century ago, David Hilbert stepped to the podium at a special meeting of the Gottingen Academy of Sciences to recall the achievements of his close friend Hermann Minkowski. Just one month earlier, on 12 January 1909, the 43-year-old Minkowski had died unexpectedly after suffering a ruptured appendix, leaving those close to him in a state of shock. None was more deeply affected than Hilbert, whose memorial lecture (Hilbert 1910) reflects the deep sense of personal loss he felt at that time:

The Role of Patient-Specific Morphological Features of the Left Atrial Appendage on the Thromboembolic Risk Under Atrial Fibrillation

2022

BackgroundA large majority of thrombi causing ischemic complications under atrial fibrillation (AF) originate in the left atrial appendage (LAA), an anatomical structure departing from the left atrium, characterized by a large morphological variability between individuals. This work analyses the hemodynamics simulated for different patient-specific models of LAA by means of computational fluid–structure interaction studies, modeling the effect of the changes in contractility and shape resulting from AF.MethodsThree operating conditions were analyzed: sinus rhythm, acute atrial fibrillation, and chronic atrial fibrillation. These were simulated on four patient-specific LAA morphologies, each…

Acute appendicitis and endometriosis: Retrospective analysis in emergency setting

2013

Introduction. The aim of this study is to evaluate the incidence of appendiceal and pelvic endometriosis in a population with diagnosis of acute appendicitis in an emergency setting. Materials and methods. We carried out a retrospective study in the period between January 2010 and October 2013. We performed 429 appendectomy including 233 in female subjects (54.3%). In all patients of childbearing age, we did β-hCG urine test to rule out the presence of an extra-uterine pregnancy. Results. 127 of 233 patients received a laparoscopic approach (54.5%). The median age was 29 years-old (range 17-68). The diagnosis of appendiceal and/or pelvic endometriosis was performed in 10 patients (4.3%): 9 …

The association between appendicitis severity and patient age with appendiceal neoplasm histology—a population-based study

2022

Abstract Purpose Recent studies have reported alarming appendiceal tumor rates associated with complicated acute appendicitis, especially in patients presenting with a periappendicular abscess. However, the data on histology of appendiceal tumors among acute appendicitis patients is limited, especially in patient cohorts differentiating between uncomplicated and complicated acute appendicitis. We have previously reported the association of increased appendiceal tumor prevalence with complicated acute appendicitis in this population-based study. The objective of this secondary analysis was to evaluate the association of both appendicitis severity and patient age with appendiceal tumor histol…

A New Early Cambrian Lobopod-Bearing Animal (Murero, Spain) and the Problem of the Ecdysozoan Early Diversification

2011

A new xenusian, Mureropodia apae gen. and sp. nov., is found in the lower Cambrian of the Murero Lagerstatte in the Cadenas Ibericas, NE Spain. In Mureropodia, the lobopod length/body width ratio reveals that this animal hardly was able to walk on the bottom surface. Possibly, it could use the limbs for anchoring the body to the substrate. A well-developed dermomuscular sac of circular and longitudinal muscular systems as well as probably retractile proboscis fit such an interpretation. The ground plan of the Xenusia includes a vermiform body; a proboscis or mouth cone; paired lobopods with claws; a cuticle displaying a repeated anatomical patterning; a straight digestive tract with termina…
