Medical Physics: forming and testing solutions to clinical problems
According to the European Federation of Organizations for Medical Physics (EFOMP) policy statement No. 13, âThe rapid advance in the use of highly sophisticated equipment and procedures in the medical field increasingly depends on information and communication technology. In spite of the fact that the safety and quality of such technology is vigorously tested before it is placed on the market, it often turns out that the safety and quality is not sufficient when used under hospital working conditions. To improve safety and quality for patient and users, additional safeguards and related monitoring, as well as measures to enhance quality, are required. Furthermore a large number of accidents and incidents happen every year in hospitals and as a consequence a number of patients die or are injured. Medical Physicists are well positioned to contribute towards preventing these kinds of eventsâ. The newest developments related to this increasingly important medical speciality were presented during the 8th European Conference of Medical Physics 2014 which was held in Athens, 11â13 September 2014 and hosted by the Hellenic Association of Medical Physicists (HAMP) in collaboration with the EFOMP and are summarized in this issue
Targeting of incoming retroviral Gag to the centrosome involves a direct interaction with the dynein light chain 8.
International audienceThe role of cellular proteins in the replication of retroviruses, especially during virus assembly, has been partly unraveled by recent studies. Paradoxically, little is known about the route taken by retroviruses to reach the nucleus at the early stages of infection. To get insight into this stage of virus replication, we have studied the trafficking of foamy retroviruses and have previously shown that incoming viral proteins reach the microtubule organizing center (MTOC) prior to nuclear translocation of the viral genome. Here, we show that incoming viruses concentrate around the MTOC as free and structured capsids. Interestingly, the Gag protein, the scaffold component of viral capsids, targets the pericentrosomal region in transfected cells in the absence of any other viral components but in a microtubule- and dynein/dynactin-dependent manner. Trafficking of Gag towards the centrosome requires a minimal 30 amino acid coiled-coil motif in the N-terminus of the molecule. Finally, we describe a direct interaction between Gag and dynein light chain 8 that probably accounts for the specific routing of the incoming capsids to the centrosome prior to nuclear import of the viral genome
Vector-borne transmission of Zika virus in Europe, southern France, August 2019
International audienceOn 1 October 2019, a locally-acquired Zika virus disease case was laboratory confirmed in HyĂšres, Var department. Active case finding identified two additional locally-acquired cases living within 90 m, with symptom onset 8 days before the index case. Extensive patient interviews did not yield information supporting transmission through sexual contact or substances of human origin. Vector-borne transmission by local Aedes albopictus mosquitoes is the most likely mode of transmission. Here we describe the public health response
