Changes in trunk posture and muscle responses in standing during pregnancy and postpartum
2018
Este artículo se encuentra disponible en la página web de la revista en la siguiente URL: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0194853 The aim of this study was to analyze the position of the lumbopelvic region and the muscle activation of erector spinae and biceps femoris muscles in a group of pregnant women in the third trimester. The hypothesis was that pregnancy-related biomechanical and morphological changes modify the position of the lumbopelvic region and the activation of extensor muscles. The position of the lumbar spine and pelvis in the sagittal plane, and the EMG activity of the erector spinae and biceps femoris muscles, were recorded during standing…
A Novel Mathematical Model For TLCD: Theoretical And Experimental Investigations
2014
In this paper, a novel mathematical model for the Tuned Liquid Column Damper (TLCD) is presented. Taking advantages of fractional derivatives and related concepts, a new equation of motion of the liquid inside the TLCD is obtained. Experimental laboratory tests have been performed in order to validate the proposed linear fractional formulation. Comparison among experimental results, numerical obtained using the classical formulation and numerical with the new linear fractional formulation are reported. Results in frequency domain show how the new linear fractional formulation can predict the real behavior of such a passive vibration control system, more correctly than the classical mathemat…
Anxiety and the severity of Tension-Type Headache mediate the relation between headache presenteeism and workers’ productivity
2018
The primary objective of this study was to explore the mechanisms and conditions whereby Tension-Type Headache (TTH) presenteeism relates to health-related loss of productivity as a result of both reduced physical and mental health. To this end, Structural Equation Modeling (SEM) was used to conduct a secondary data analysis of a randomized clinical trial involving 78 Tension-type Headache (TTH) patients. The results showed that TTH presenteeism did not directly relate to health-related loss of productivity, either due to physical, or mental health problems. However, through anxiety-state, TTH presenteeism decreased patients' productivity, as consequence of reduced physical and mental healt…
Épidémiologie des leucémies aiguës
2015
Resume Les leucemies aigues, lymphoides et myeloides representent 10 a 15% des hemopathies malignes et sont des affections rares qui en dehors de quelques formes sont souvent de pronostic pejoratif. Les leucemies aigues myeloides (LAM) ont une incidence stable au cours du temps qui varie de 2,5 a 3,5/100 000 habitants/an dans les pays occidentaux. L’âge median de survenue est de 63 ans. En dehors des formes avec anomalies cytogenetiques recurrentes, en particulier les LA promyelocytaires qui ont une survie a 5 ans voisine de 60%, les LAM ont une survie a 5 ans inferieure a 20% et qui ne s’ameliore pas au fil du temps. Les leucemies aigues lymphoblastiques (LAL) ont une incidence proche de 1…
La diagnostica di laboratorio delle dislipidemie
2016
Dyslipidemias represent a major contributor to cardiovascular risk in Western countries, including Italy, that can be modified. After examining familial dyslipidemias and describing the essential issues for clinical and laboratory diagnostics, the paper considers the laboratory testing in detail. The preanalytical sources of variability (biological, sample collection and handling) are reviewed and essential indications to reduce them are given. About the analytical variability, the paper examines the methods routinely used for measuring the basic lipid parameters (total, LDL and HDL cholesterol, triglycerides and apolipoproteins A-I and B) and describes the state of art of the standardizati…
Attività di SIBioC - Medicina di Laboratorio e soddisfazione dei soci: Risultati di un questionario
2017
This report presents the results of a survey performed on Oct-Nov 2015 on SIBioC member satisfaction. The survey addressed event attendance/received value, networking opportunities and overall benefit of SIBioC membership. An on-line questionnaire was sent to all SIBioC members through the web-based SurveyMonkey platform and the resulting database was statistically analyzed. The respondents (514 out of 2000 members) can be considered a representative sample of the associates, since different professional branches were represented proportionally. The large majority of respondents were familiar with SIBioC Newsletter and expressed a positive opinion on it. 71% of the respondents declared to a…

Cytochemischer Nachweis von Hydrolasen in Pilzzellen
1969
Die Anwendbarkeit der Tetrazoliumsalz-Methode (Lojda, 1965) und der Brom-naphthyl-glykosid-Methode (Cohen u. Mitarb., 1952; Rutenburg u. Mitarb., 1958, 1960) zum cytochemischen Nachweis von β-Galactosidase (E.C. 3.2.1.23), α-Glucosidase (E.C. 3.2.1.20) und β-Glucosidase (E.C. 3.2.1.21) in den Zellen der Pilze Neurospora crassa, Aspergillus oryzae und Saccharomyces cerevisiae (Vorkultur auf Nahrboden mit Zusatzen von Enzyminduktoren) wurde untersucht. In allen Fallen waren die TS-Medien — was die Art der Enzymlokalisation, die Empfindlichkeit und Spezifitat betrifft — dem Brom-naphthylglykosid-Verfahren uberlegen. Bei N. crassa und A. oryzae liesen sich β-Galactosidase, α- und β-Glucosidase,…
Der cytochemische Nachweis von Cytochromoxydase und Peroxydasen bei Pilzen
1967
Verschiedene Nachweisverfahren fur Cytochromoxydase und Peroxydase wurden an den Pilzen Neurospora crassa, Oospora lactis und Saccharomyces cerevisiae getestet und die jeweils beste zur Zeit verfugbare Methode ermittelt. Zur cytochemischen Lokalisation der Cytochromoxydase (E.C. 1.9.3.1) ist das Amin-Amin-Verfahren von Burstone (1960) mit den Reaktionspartnern p-Aminodiphenylamin und Variaminblau B (p-Methoxy-p′-aminodiphenylamin) zu empfehlen, wobei die optimale Inkubationszeit bei allen Pilzen 30 min betragt. Die braunroten Reaktionsprodukte sind im Cytoplasma aller Pilze gleichmasig verteilt. Eine Nachbehandlung der Praparate in Cobaltacetat-Losung (Burstone, 1960) sowie die Zwischenscha…
Untersuchungen zum cytochemischen Nachweis von Glukoseoxydase (E.C. 1.1.3.4) beiAspergillus niger
1966
Mit Hilfe des Tetrazoliumsalzes Nitro-BT sowie des Intermediators Phenazinmethosulfat wurde die intrazellulare Glukoseoxydase (E.C. 1.1.3.4) vonAspergillus niger cytochemisch nachgewiesen, wobei biochemische Befunde zur Stutzung der Spezifitat der Reaktion herangezogen wurden.
