Abstract

International audience; We welcome the comment by Michard et al. (2013) as it gives us the opportunity to better discuss the Jurassic–Cretaceous magmatism of the High Atlas (Morocco). In their comment, Michard et al. (2013) focus on three main points which are: (i) the age of the basalts from Naour, (ii) the structural history of the Central High Atlas and (iii) the geodynamic significance of the related Jurassic–Cretaceous magmatism. We will address these questions in the following sections.

Abstract

Background: The Hepatitis B virus (HBV) vaccine is used worldwide as an efficient tool to prevent the occurrence of chronic HBV infection and the subsequent liver disease. However, despite decades of vaccination campaigns, millions of new infections are still reported every year. Here, we aimed to assess the nationwide HBV vaccination coverage in Mauritania as well as the presence of protective levels of the antibodies against HBV surface antigen (HBsAb) following vaccination in a sample of children immunized as infants., Methods: To evaluate the frequency of fully vaccinated and seroprotected children in Mauritania, a prospective serological study was conducted in the capital. First, we evaluated the pediatric HBV vaccine coverage in Mauritania between 2015 and 2020. Then, we examined the level of antibodies against HBV surface antigen (HBsAb) in 185 fully vaccinated children (aged 9 months to 12 years) by ELISA using the VIDAS hepatitis panel for Minividas (Biomerieux). These vaccinated children were sampled in 2014 or 2021., Results: In Mauritania, between 2016 and 2019, more than 85% of children received the complete HBV vaccine regimen. While 93% of immunized children between 0 and 23 months displayed HBsAb titer >10 IU/L, the frequency of children with similar titers decreased to 63, 58 and 29% in children aged between 24-47, 48-59 and 60-144 months, respectively., Conclusions: A marked reduction in the frequency of HBsAb titer was observed with time, indicating that HBsAb titer usefulness as marker of protection is short lived and prompting the need for more accurate biomarkers predictive of long-term protection.

Abstract

The immunolocalization of presenilin in human brain was studied using two antibodies raised against different portions of presenilin 1 (S182) protein. A granular staining was found in the cytoplasm of neurons in cortical layers III and V. One of the antibodies, also reactive to presenilin 2 (E5-1) protein, additionally stained dendrites and axons. This was seen in normal brains as well as in brains affected by Alzheimer's disease. Less prominent immunolabeling was noted in some senile plaques. No relationship to neurofibrillary tangles was found in double-labeling experiments combined with anti-paired helical filament-tau antibody (AT8). The widespread expression of presenilin in normal brain suggests a physiological role of the protein.
