Risk of Virus Contamination Through Surgical Smoke During Minimally Invasive Surgery: A Systematic Review of the Literature on a Neglected Issue Revi…

2020

Abstract Context The coronavirus disease 2019 (COVID-19) pandemic raised concerns about the safety of laparoscopy due to the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diffusion in surgical smoke. Although no case of SARS-CoV-2 contagion related to surgical smoke has been reported, several international surgical societies recommended caution or even discouraged the use of a laparoscopic approach. Objective To evaluate the risk of virus spread due to surgical smoke during surgical procedures. Evidence acquisition We searched PubMed and Scopus for eligible studies, including clinical and preclinical studies assessing the presence of any virus in the surgical smoke fr…

A Model for Assessing the Magnitude and Distribution of Sheath Currents in Medium and High-Voltage Cable Lines

2020

In this article, the authors discuss a simulation model to study the effect of cross-bonding of metallic sheaths, and/or nonmagnetic armors, of single-core medium- and high-voltage cables in the same circuit. In single-core cables, the resistive losses due to the induced circulating currents in cable sheaths or armors cause an increase of the cable temperature, which therefore reduces its ampacity. This is a serious issue affecting the distribution and transmission lines. In addition, the risk of electric shock due to induced voltages may be present if a person is in contact with the armor/sheath at its unbounded end. For these reasons, special bonding techniques of metal sheaths are employ…

A highly selective, Hg2+ triggered hydrogelation: modulation of morphology by chemical stimuli

2014

We report the first Hg2+ selective hydrogelation by 4´-[4-(4- aminophenyl)phenyl]-2,2´:6´,2´´-terpyridine. The gel showed remarkable response towards specific chemical agents such as benzo-18-crown-6 ether and K+ which enabled extensive 10 modulation of the gel morphology. peerReviewed

Transmission processes of indigenous Pedi music

2017

There has been unsatisfactory integration of traditional music into education, despite the fact that the Ministry of Education advocates its use, stating that education should ‘preserve South Africa’s cultural practice; develop an appreciation for the practice of one’s culture; and develop a sense of respect for other people’s culture’. South Africa is in need of a music education philosophy that is culturally embedded, cognisant of the societal context in which it is to function, and informed by South African ideas and philosophy of life. This study entails sourcing the Ethnomusicological and Anthropological focus in musicology for purposes of providing a better understanding on music and …

The nasus gland: A new gland in soldiers of Angularitermes (Termitidae, Nasutitermitinae)

2015

Termites have developed many exocrine glands, generally dedicated to defence or communication. Although a few of these glands occur in all termite species, or represent synapomorphies of larger clades, others are morphological innovations of a single species, or a few related species. Here, we describe the nasus gland, a new gland occurring at the base of the nasus of Angularitermes soldiers. The nasus gland is composed of class 1, 2, and 3 secretory cells, a rare combination that is only shared by the sternal and tergal glands of some termites and cockroaches. The ultrastructural observations suggest that the secretion is produced by class 2 and 3 secretory cells, and released mostly by cl…

Cetacean Morbillivirus: Current Knowledge and Future Directions

2014

We review the molecular and epidemiological characteristics of cetacean morbillivirus (CeMV) and the diagnosis and pathogenesis of associated disease, with six different strains detected in cetaceans worldwide. CeMV has caused epidemics with high mortality in odontocetes in Europe, the USAand Australia. It represents a distinct species within the Morbillivirusgenus. Although most CeMV strains are phylogenetically closely related, recent data indicate that morbilliviruses recovered from Indo-Pacific bottlenose dolphins (Tursiops aduncus), from Western Australia, and a Guiana dolphin (Sotalia guianensis), from Brazil, are divergent. The signaling lymphocyte activation molecule (SLAM) cell rec…

Diplostomiasis ( Diplostomum spathaceum and related species).

This book chapter describes various aspects of diplostomiasis caused by Diplostomum spathaceum: diagnosis, epidemiology, life cycle, transmission, developmental stages, population dynamics, effects of climate change on parasite distribution, and disease control and prevention. peerReviewed

Mechanical Coupling Between Muscle-Tendon Units Reduces Peak Stresses

2017

The presence of mechanical linkages between synergistic muscles and their common tendons may distribute forces among the involved structures. We review studies, using humans and other animals, examining muscle and tendon interactions and discuss the hypothesis that connections between muscle bellies and within tendons may serve as a mechanism to distribute forces and mitigate peak stresses. peerReviewed

«Don aux églises et don d'églises dans le sud-est de la Gaule : du testament d'Abbon (739) aux chartes du début du XIe siècle»

2005

International audience; Aux vues de la documentation disponible concernant le sud-est de la Gaule, le traitement comparé des formes de transmission des patrimoines entre ceux qui disposent d'un honor ou d'une charge quelconque et ceux qui n'en disposent pas, ne peut être effectué qu'aux deux extrêmes de la fourchette chronologique qui nous occupe dans cette rencontre (VIIIe-Xe siècles). Ainsi, je propose d'analyser, en guise d'introduction, le testament d'Abbon, de 739, fondateur de l'abbaye de la Novalèse, recteur de la région de Suse et de la Maurienne, et probablement le dernier patrice de Provence. Ce document permet d'esquisser un tableau des cercles de parenté à l'intérieur desquels c…
