Embryological development of the human cranio-facial arterial system : a pictorial review

Bertulli, Lorenzo ; Robert, Thomas

In: Surgical and radiologic anatomy, 2021, p. 13 p

The embryological development of the cerebral vasculature is very complex. Historical and also more recent studies based on human embryos, comparative anatomy and cerebral angiographies allowed us to better understand this vasculature development. The knowledge and understanding of such embryological development are important for physicians interested in neurovascular pathologies. Indeed, all...

Diabetes mellitus is a risk factor for prolonged SARS-CoV-2 viral shedding in lower respiratory tract samples of critically ill patients

Buetti, Niccolò ; Trimboli, Pierpaolo ; Mazzuchelli, Timothy ; Lo Priore, Elia ; Balmelli, Carlo ; Trkola, Alexandra ; Conti, Marco ; Martinetti, Gladys ; Elzi, Luigia ; Ceschi, Alessandro ; Consonni, Vera ; Ogna, Adam ; Forni-Ogna, Valentina ; Bernasconi, Enos

In: Endocrine, 2020, p. 7 p

The length of time a critically ill coronavirus disease 2019 (COVID-19) patient remains infectious and should therefore be isolated remains unknown. This prospective study was undertaken in critically ill patients to evaluate the reliability of single negative real-time polymerase chain reaction (RT-PCR) in lower tracheal aspirates (LTA) in predicting a second negative test and to analyze...

Typical imaging finding of hepatic infections: a pictorial essay

Malekzadeh, Sonaz ; Widmer, Lucien ; Salahshour, Faezeh ; Egger, Bernhard ; Ronot, Maxime ; Thoeny, Harriet C.

In: Abdominal Radiology, 2020, p. -

Hepatic infections are frequent in clinical practice. Although epidemiological, clinical and laboratory data may suggest hepatic infection in certain cases, imaging is nearly always necessary to confirm the diagnosis, assess disease extension and its complications, evaluate the response to treatment, and sometimes to make differential diagnoses such as malignancies. Ultrasound (US) is usually...

Role of ETS1 in the transcriptional network of diffuse large B cell lymphoma of the activated B cell-like type

Priebe, Valdemar ; Sartori, Giulio ; Napoli, Sara ; Chung, Elaine Yee Lin ; Cascione, Luciano ; Kwee, Ivo ; Arribas, Alberto Jesus ; Mensah, Afua Adjeiwaa ; Rinaldi, Andrea ; Ponzoni, Maurilio ; Zucca, Emanuele ; Rossi, Davide ; Efremov, Dimitar ; Lenz, Georg ; Thome, Margot ; Bertoni, Francesco

In: Cancers, 2020, vol. 12, no. 7, p. 17 p

Diffuse large B cell lymphoma (DLBCL) is a heterogenous disease that has been distinguished into at least two major molecular entities, the germinal center-like B cell (GCB) DLBCL and activated-like B cell (ABC) DLBCL, based on transcriptome expression profiling. A recurrent ch11q24.3 gain is observed in roughly a fourth of DLBCL cases resulting in the overexpression of two ETS transcription...

Changes in breast cancer management during the Corona Virus Disease 19 pandemic : an international survey of the European Breast Cancer Research Association of Surgical Trialists (EUBREAST)

Gasparri, Maria Luisa ; Gentilini, Oreste Davide ; Lueftner, Diana ; Kuehn, Thorsten ; Kaidar-Person, Orit ; Poortmans, Philip

In: The breast, 2020, vol. 52, p. 110-115

Background: Corona Virus Disease 19 (COVID-19) had a worldwide negative impact on healthcare systems, which were not used to coping with such pandemic. Adaptation strategies prioritizing COVID-19 patients included triage of patients and reduction or re-allocation of other services. The aim of our survey was to provide a real time international snapshot of modifications of breast cancer...

Maintenance fluid therapy with saline, dextrose-supplemented saline or lactated Ringer in childhood: short-term metabolic effects

Ricciuti, Alessandra ; Milani, Gregorio P. ; Tarantino, Silvia ; Ghilardi, Roberta ; Lava, Sebastiano A.G. ; Alberzoni, Marco ; Bianchetti, Mario G. ; Agostoni, Carlo

In: Nutrients, 2020, vol. 12, no. 5, p. 8 p

Maintenance with isotonic fluids is recommended in children with gastroenteritis and failure of oral rehydration therapy. However, little is known on the short-term effects of the commonly prescribed intravenous solutions on metabolic balance in children. The aim of this study is to report on our experience with normal saline, dextrose-supplemented saline and lactated Ringer solution. Methods:...

Influenza vaccination induces NK-cell-mediated type-II IFN response that regulates humoral immunity in an IL-6-dependent manner

Farsakoglu, Yagmur ; Palomino-Segura, Miguel ; Latino, Irene ; Zanaga, Silvia ; Chatziandreou, Nikolaos ; Pizzagalli, Diego Ulisse ; Rinaldi, Andrea ; Bolis, Marco ; Sallusto, Federica ; Stein, Jens V. ; Gonzalez, Santiago F.

In: Cell reports, 2019, vol. 26, no. 9, p. 2307-2315.e5

The role of natural killer (NK) cells in the immune response against vaccines is not fully understood. Here, we examine the function of infiltrated NK cells in the initiation of the inflammatory response triggered by inactivated influenza virus vaccine in the draining lymph node (LN). We observed that, following vaccination, NK cells are recruited to the interfollicular and medullary areas of...

Induction of potent neutralizing antibody responses by a designed protein nanoparticle accine for respiratory syncytial virus

Marcandalli, Jessica ; Fiala, Brooke ; Ols, Sebastian ; Perotti, Michela ; de van der Schueren, Willem ; Snijder, Joost ; Hodge, Edgar ; Benhaim, Mark ; Ravichandran, Rashmi ; Carter, Lauren ; Sheffler, Will ; Brunner, Livia ; Lawrenz, Maria ; Dubois, Patrice ; Lanzavecchia, Antonio ; Sallusto, Federica ; Lee, Kelly K. ; Veesler, David ; Correnti, Colin E. ; Stewart, Lance J. ; Baker, David ; Loré, Karin ; Perez, Laurent ; King, Neil P.

In: Cell, 2019, vol. 177, no. 6, p. 1420-1431.e17

Respiratory syncytial virus (RSV) is a worldwide public health concern for which no vaccine is available. Elucidation of the prefusion structure of the RSV F glycoprotein and its identification as the main target of neutralizing antibodies have provided new opportunities for development of an effective vaccine. Here, we describe the structure-based design of a self-assembling protein ...

Schwann cells ER-associated degradation contributes to myelin maintenance in adult nerves and limits demyelination in CMT1B mice

Volpi, Vera G. ; Ferri, Cinzia ; Fregno, Ilaria ; Del Carro, Ubaldo ; Bianchi, Francesca ; Scapin, Cristina ; Pettinato, Emanuela ; Solda, Tatiana ; Feltri, M. Laura ; Molinari, Maurizio ; Wrabetz, Lawrence ; D’Antonio, Maurizio

In: PLOS genetics, 2019, vol. 15, no. 4, p. e1008069

In the peripheral nervous system (PNS) myelinating Schwann cells synthesize large amounts of myelin protein zero (P0) glycoprotein, an abundant component of peripheral nerve myelin. In humans, mutations in P0 cause the demyelinating Charcot-Marie-Tooth 1B (CMT1B) neuropathy, one of the most diffused genetic disorders of the PNS. We previously showed that several mutations, such as the...

PECAM-1 stabilizes blood-brain barrier integrity and favors paracellular T-Cell diapedesis across the blood-brain barrier during neuroinflammation

Wimmer, Isabella ; Tietz, Silvia ; Nishihara, Hideaki ; Deutsch, Urban ; Sallusto, Federica ; Gosselet, Fabien ; Lyck, Ruth ; Muller, William A. ; Lassmann, Hans ; Engelhardt, Britta

In: Frontiers in immunology, 2019, vol. 10, p. 711

Breakdown of the blood-brain barrier (BBB) and increased immune cell trafficking into the central nervous system (CNS) are hallmarks of the pathogenesis of multiple sclerosis (MS). Platelet endothelial cell adhesion molecule-1 (PECAM-1; CD31) is expressed on cells of the vascular compartment and regulates vascular integrity and immune cell trafficking. Involvement of PECAM-1 in MS pathogenesis...
