Radiolabeling of a polypeptide polymer for intratumoral delivery of alpha-particle emitter, 225Ac, and beta-particle emitter, 177Lu
2021
Introduction: Radiotherapy of cancer requires both alpha- and beta-particle emitting radionuclides, as these radionuclide types are efficient at destroying different types of tumors. Both classes of radionuclides require a vehicle, such as an antibody or a polymer, to be delivered and retained within the tumor. Polyglutamic acid (pGlu) is a polymer that has proven itself effective as a basis of drug-polymer conjugates in the clinic, while its derivatives have been used for pretargeted tumor imaging in a research setup. trans-Cyclooctene (TCO) modified pGlu is suitable for pretargeted imaging or therapy, as well as for intratumoral radionuclide therapy. In all cases, it becomes indirectly ra…
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…
Illuminating a Phytochrome Paradigm – a Light-Activated Phosphatase in Two-Component Signaling Uncovered
2020
ABSTRACTBacterial phytochrome photoreceptors usually belong to two-component signaling systems which transmit environmental stimuli to a response regulator through a histidine kinase domain. Phytochromes switch between red light-absorbing and far-red light-absorbing states. Despite exhibiting extensive structural responses during this transition, the model bacteriophytochrome fromDeinococcus radiodurans(DrBphP) lacks detectable kinase activity. Here, we resolve this long-standing conundrum by comparatively analyzing the interactions and output activities of DrBphP and a bacteriophytochrome fromAgrobacterium fabrum(AgP1). Whereas AgP1 acts as a conventional histidine kinase, we identify DrBp…
Bone loss around narrow implants versus standard diameter implants: Retrospective 2-years case-control study
2019
Background The objectives were to evaluate the bone loss (BL) around narrow diameter implants (3.3 mm) 2 years after implant loading and compare with the bone loss around conventional-diameter implants (4.1 mm), as well as with clinical and anatomical variables. 2-years follow-up. Material and Methods Cases: 20 patients either gender-age, narrow implants (Straumann TM-SLA, diameter 3.3 mm); Control: 20 patients matching for gender-age, conventional implants (Straumann TM-SLA, diameter 4.1). Total 82 implants (31 narrow implants and 51 conventional implants) in 40 patients. To avoid statistical bias, a cluster of one implant per patient was randomly selected (20 narrow implants and 20 conven…
Regenerative endodontic procedure combined with apical surgery of a necrotic permanent incisor with extensive periapical lesion using plasma rich in …
2021
Background The aim of this case report is to describe the step-by step and outcomes of a treatment approach which simultaneously combines a Regenerative Endodontic Procedure (REP) and apical surgery using PRGF as treatment of a post-traumatic necrotic permanent central incisor with extensive periapical lesion and undeveloped apex in a 16 years-old patient. Case description A 16 years-old patient with an extensive periapical lesion in the maxillary central incisor was treated with a combination of REP and periapical surgery in the same visit. A Bi- antibiotic paste (BAP) was used to priorly disinfect the canal, which was posteriorly sealed with MTA placed over a PRGF clot at the same time th…

Facing a Toxic Object
2021
AbstractOver the past decades, industrial societies have produced a range of substances whose effects humans increasingly identify as toxic—a prominent example is radioactive waste and the question of its disposal. This fabricated “object of modernity” not only calls for the knowledge of the natural sciences, it also affects society at large in its immense challenge of figuring out how to dispose of this material and altogether “detoxify” society from its hazardous activity. The contribution develops a heuristic perspective on toxic objects, exemplified by analyzing documents with a focus on how different societal actors in Germany problematize high-level radioactive waste (HLW) in the cont…
How to diagnose and treat abdominal compartment syndrome after endovascular and open repair of ruptured abdominal aortic aneurysms
2014
Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are frequently encountered in patients treated for ruptured abdominal aortic aneurysms (rAAA) and carry a high morbidity and mortality risk. Despite these facts, IAH/ACS are still overlooked by many physicians, timely diagnosis is missed and treatment often inadequate. All staff involved in the treatment of rAAA should be aware of the risk factors predicting IAH/ACS, the profound implications and derangements on all organ systems, the clinical presentation, the appropriate measurement of intra-abdominal pressure to detect IAH/ACS and the current treatment options for these detrimental syndromes. This comprehensive r…
