Bacteriophage imaging : past, present and future

2018

The visualization of viral particles only became possible after the advent of the electron microscope. The first bacteriophage images were published in 1940 and were soon followed by many other publications that helped to elucidate the structure of the particles and their interaction with the bacterial hosts. As sample preparation improved and new technologies were developed, phage imaging became important approach to morphologically classify these viruses and helped to understand its importance in the biosphere. In this review we discuss the main milestones in phage imaging, how it affected our knowledge on these viruses and recent developments in the field. peerReviewed

Giant cell arteritis (Horton's disease) in very elderly patients aged 80 years and older: A study of 25 cases

2015

Aim Analysis of the characteristics of very elderly patients with giant cell arteritis (GCA). Methods Patients aged 80 years and older diagnosed with GCA in our department between 1 January 2002 and 31 July 2008 were retrospectively included. For each patient, we recorded general characteristics, reason(s) for hospitalization, specialty of the physician or department that referred the patient to us, medical history, treatment at admission, GCA clinical features, time to diagnosis of GCA, biological screening and GCA treatment. Results We analyzed 25 clinical records, 18 women and seven men with a mean age of 83.9 years. General weakness, visual loss and inflammatory syndrome were the princi…

El diagnóstico de la crisis de la cultura en España: del recorte público a la crisis sistémica

2016

Since its invention in the fifties, cultural policy has been subject of analysis and reflection by Social Sciences. However, Spain, due to Franco period, has a number of distinguishing features as compared to Western European democracies. With the restoration of democracy, Spain acquires the dominant paradigm of a democratic cultural policy based on freedom, pluralism and the right to culture. However, after decades of democratic governments, diagnosis of cultural policy in Spain shows signs of systemic crisis, added to the impact of the global financial crisis at the beginning of the XXI century. In this context, scholars, using the Delphi method along with secondary sources, identify a se…

How We Forgot Who Discovered DNA: Why It Matters How You Communicate Your Results

2019

One hundred and fifty years ago, a hopeful young researcher reported a recent discovery he had made. Working in the bowels of a medieval castle in the German city of Tübingen, he had isolated a then entirely new type of molecule. This was the birth of a field that would fundamentally change the course of biology, medicine, and beyond. His discovery: DNA. His name: Friedrich Miescher. In this article, the authors try to find answers to the question why-despite the fact that virtually everyone nowadays knows DNA-hardly anyone remembers the man who discovered it. In the history of science, the discovery of DNA was a seminal moment. Why then did it not enter into public memory? Ground-breaking …

Entre éducation populaire et propagande syndicale : les cours radiophoniques de la CGT sous le Front Populaire

2011

Notre article se propose d’aborder une expérience originale d’éducation populaire, souvent citée mais finalement assez peu étudiée : les cours radiodiffusés du Centre confédéral d’éducation ouvrière de la CGT, durant le Front populaire. Le CCEO qui, dès sa création en 1933, s’est voulu un outil de démocratisation du savoir va en effet avoir l’opportunité d’accéder à un média de masse à partir de janvier 1937 et d’élargir son audience. Nous verrons donc comment pendant trois ans, à travers l’émission La Voix de la CGT, le syndicat a investi les ondes, fait l’apprentissage des exigences particulières de l’exercice radiophonique et s’est efforcé de concilier mission éducative et tentation prop…

Policiers, gendarmes et signalement descriptif. Représentations, apprentissages et pratiques d'une nouvelle technique de police judiciaire, en France…

2006

À partir des années 1880, les nouveaux procédés d’identification développés par Alphonse Bertillon à la Préfecture de police de Paris représentent des moyens modernes et efficaces de police judiciaire face à une criminalité perçue comme irrésistible. Parmi ceux-ci, le signalement descriptif, ou « portrait parlé », est réputé permettre la reconnaissance infaillible d’un individu dont les traits du visage auraient été minutieusement décrits par cette technique particulière. Fait notable, sans doute inédit et sans équivalent alors, cette technique est enseignée aux divers acteurs de la police française – policiers de la Préfecture de police, de la Sûreté générale, mais aussi gendarmes et garde…

Kinship, acquired and inherited status, and population structure at the Early Bronze Age Mokrin necropolis in northern Serbia

2020

AbstractTwenty-four ancient genomes with an average sequencing coverage of 0.85±0.25 X were produced from the Mokrin necropolis, an Early Bronze Age (2,100-1,800 BC) Maros culture site in Serbia, to provide unambiguous identification of biological sex, population structure, and genetic kinship between individuals. Of the 24 investigated individuals, 15 were involved in kinship relationships of varying degrees, including 3 parent-offspring relationships. All observed parent-offspring pairs were mother and son. In addition to the absence of biological daughters, we observed a number of young women and girls with no biological relatives in our sample. These observations, together with the high…

The Genetic History of Northern Europe

2017

Recent ancient DNA studies have revealed that the genetic history of modern Europeans was shaped by a series of migration and admixture events between deeply diverged groups. While these events are well described in Central and Southern Europe, genetic evidence from Northern Europe surrounding the Baltic Sea is still sparse. Here we report genome-wide DNA data from 24 ancient North Europeans ranging from ~7,500 to 200 calBCE spanning the transition from a hunter-gatherer to an agricultural lifestyle, as well as the adoption of bronze metallurgy. We show that Scandinavia was settled after the retreat of the glacial ice sheets from a southern and a northern route, and that the first Scandinav…
