Most studies on the docking of ivermectin on the spike protein of SARS-CoV-2 concern the receptor binding domain (RBD) and, more precisely, the RBD interface recognized by the ACE2 receptor. The N-terminal domain (NTD), which controls the initial attachment of the virus to lipid raft gangliosides, has not received the attention it deserves. In this study, we combined molecular modeling and physicochemical approaches to analyze the mode of interaction of ivermectin with the interface of the NTD-facing lipid rafts of the host cell membrane.

We previously reported that membrane-type 5-matrix metalloproteinase (MT5-MMP) deficiency not only reduces pathological hallmarks of Alzheimer's disease (AD) in 5xFAD (Tg) mice in vivo but also impairs interleukin-1 beta (IL-1β)-mediated neuroinflammation and Aβ production in primary Tg immature neural cell cultures after 11 days in vitro. We now investigate the effect of MT5-MMP on incipient pathogenic pathways that are activated in cortical primary cultures at 21-24 days in vitro (DIV), during which time neurons are organized into a functional mature network. Using wild-type (WT), MT5-MMP (MT5), 5xFAD (Tg), and 5xFADxMT5-MMP (TgMT5) mice, we generated primary neuronal cultures that were exposed to IL-1β and/or different proteolytic system inhibitors.

How to talk to parents.

Pediatr Radiol

January 2025

Paediatric and prenatal radiology department, Hôpital Timone Enfants, APHM, 264 rue Saint Pierre, Marseille, 13005, France.

Effective communication with the child and his/her parents is of paramount importance in our daily work in paediatric radiology to establish a trusting relationship and enhance satisfaction for both patients and physicians. Although communication skills and empathy can be effectively taught, and efforts have been made in this area in medical schools, there is still much room for improvement, as communication skills tend to decline throughout medical training. Certain methods are valuable for conducting effective consultations with both the child and the parents, not only when breaking bad news.

Therapie

December 2024

Service de pharmacologie médicale et clinique, centre d'évaluation et d'information sur la pharmacodépendance - addictovigilance, hôpitaux de Toulouse, université de Toulouse, 31000 Toulouse, France.

The opioid epidemic has emerged in the USA in the late 1990s and widespread to Canada, Australia, and the UK to a lesser extent in the more recent years. At the European level, several studies performed in different European countries have highlighted that prescription opioid use increased substantially over the last decade, and several proxies for misuse show a parallel increasing trend. The French addictovigilance experience on opioid analgesics is a good example of a specific dedicated monitoring, taking into account in a global and multisource perspective, patterns of utilization, population involved in problematic use, ways of acquisition and health complications.
