Killing methods in Sicilian Mafia families
2019
The Sicilian Mafia is a criminal organisation founded in Sicily which is an island south of the Italian mainland in the Mediterranean Sea. Until recently, this organization was responsible for many murders and bombings. However, recently, based on the investigations known as the “Mare Nostrum” operation, the Supreme Court convicted 67 people and sent them to prison. Some defendants were found guilty of as many as 39 murders. This article reviews the forensic analysis that was used when investigating responsibility for these Mafia murders. Our review is based on the court documents and the ballistic investigations which were carried out to evaluate the reliability of “repented” or “pentiti”…
In Memoriam : las aportaciones micrográficas del valenciano Luis Simarro (1851-1921)
2022
El pasado 19 de junio del 2021, se cumplió el centenario de la muerte del histólogovalenciano Luis Simarro Lacabra (1851-1921). La figura de Simarro prácticamente ha desapare-cido, en el momento actual, de la memoria del panorama científico y cultural espa¿nol, siendo susaportaciones micrográficas escasamente conocidas, probablemente debido a que su produccióncientífica escrita fue muy reducida.En el presente trabajo, las aportaciones micrográficas de Simarro, de las que tenemos cono-cimiento, son revisadas en el contexto de su biografía, analizando su influencia en el origen ydesarrollo de la escuela neurohistológica española que, liderada por Santiago Ramón y Cajal,es hoy universalmente r…
Measurement of residual stresses by the hole-drilling method: Influence of hole eccentricity
1979
The hole-drilling method is a semidestructive technique which allows the measurement of residual stresses. In this method, a source of error is due to the misalignment between the hole and rosette centres. This paper presents a theoretical analysis of the influence of such misalignment on the strains measured by the rosette. Formulae which give the residual stresses taking account of the hole eccentricity are derived. Finally, the errors, which affect the residual stresses when the eccentricity is neglected, are evaluated for some commercial strain-gauge rosettes especially developed for the hole-drilling method.
Cell types infected in human cytomegalovirus placentitis identified by immunohistochemical double staining
1993
Chronic villitis is almost always present in intrauterine infection with human cytomegalovirus (HCMV). The inflammatory response to this virus has been described in detail. However, little is known about the types of placental cells that may be infected by HCMV and six cases of HCMV placentitis were thus investigated to identify the vulnerable cell types. Immunohistochemical double staining analyses were performed using antibodies to HCMV immediate early antigens and to specific cellular marker proteins. Fixed connective tissue cells could be demonstrated to be the predominantly infected cell type in each placental tissue. Endothelial cells and macrophages were also found to be infected in …
Der Fr�hnachweis des Herzinfarktes durch Bestimmung der Wasserstoffionenkonzentration im Herzmuskel mit Indicatorpapier
1965
Es wird eine einfache Methode zum Fruhnachweis des Herzinfarktes beschrieben. Durch Messung der Wasserstoffionenkonzentration an Kryostatschnitten vom Herzen mit pH-Indicatorpapier wird ein bei Ratten und Katzen erzeugter Ischamiebezirk bereits 5 min nach Unterbindung einer Coronararterie im Herzmuskel nachweisbar. Die in der Literatur beschriebene Anderung der Wasserstoffionenkonzentration in einer Nekrose wird fur den Herzinfarkt bestatigt und dient zu seinem Nachweis bis zum Auftreten von lichtmikroskopisch erkennbaren Nekrosezeichen.
Comparative Studies on Vascular Endothelium in vitro
1994
Recent studies have presented evidence that the processes of hypoxaemia and reperfusion are involved in several pathogenetic mechanisms of atherosclerotic lesions. The ability of hypoxaemia to activate circulating white blood cells (WBCs) and enhance WBC-endothelial cell (EC) interactions is suspected to be a major factor in deleterious processes in the blood vessel wall. Various groups have suggested that cell adhesion molecules (CAMs), such as ICAM-1, VCAM-1 and E-selectin and their leukocyte ligands are involved in intercellular activities of the relevant cell types. We studied the effects of different oxygen tensions, simulating normoxic conditions, hypoxia and hyperoxia in vitro with t…

Hypertrophic Lichen Planus: Importance of Follow-Up and Clinicopathologic Correlation

Tissue invasiveness and non-acidic pH in human candidiasis correlate with "in vivo" expression by Candida albicans of the carbohydrate epitope recogn…
2004
Background: The morphogenetic conversion between yeast and hyphal growth forms appears to be crucial in the pathogenesis of invasive candidiasis, and can be regulated by environmental signals such as extracellular pH. Aims: To characterise the epitope recognised by monoclonal antibody 1H4, and to evaluate the expression of its corresponding epitope in Candida albicans cells under different conditions of pH and temperature, and “in vivo”, in tissue samples from patients with human candidiasis. Methods: Monoclonal antibody 1H4 was generated against the 58 kDa cell wall mannoprotein of C albicans (mp58), and was further characterised by immunoblot analysis, periodate treatment of the antigenic…
