One of the major early steps of repair is the recruitment of repair proteins at the damage site, and this is coordinated by a cascade of modifications controlled by phosphatidylinositol 3-kinase-related kinases and/or poly (ADP-ribose) polymerase (PARP). We used short interfering DNA molecules mimicking double-strand breaks (called Dbait) or single-strand(More)
Members of the Sso7d/Sac7d family are small, abundant, non-specific DNA-binding proteins of the hyperthermophilic Archaea SULFOLOBUS: Crystal structures of these proteins in complex with oligonucleotides showed that they induce changes in the helical twist and marked DNA bending. On this basis they have been suggested to play a role in organising chromatin(More)
Type II DNA topoisomerases (Topo II) are essential enzymes implicated in key nuclear processes. The recent discovery of a novel kind of Topo II (DNA topoisomerase VI) in Archaea led to a division of these enzymes into two non-homologous families, (Topo IIA and Topo IIB) and to the identification of the eukaryotic protein that initiates meiotic(More)
Insecticide resistance seriously threatens the efficacy of vector control interventions in malaria endemic countries. In Afghanistan, the status of insecticide resistance is largely unknown while distribution of long-lasting insecticidal nets has intensified in recent years. The main objective of this study was thus to measure the level of resistance to(More)
Increased DNA repair activity in cancer cells is one of their primary mechanisms of resistance to current radio- and chemotherapies. The molecule coDbait is the first candidate in a new class of drugs that target the double-strand DNA break repair pathways with the aim of overcoming these resistances. coDbait is a 32-base pair (bp) double-stranded DNA(More)
OBJECTIVE To measure prevalence of prior/current Plasmodium vivax and Plasmodium falciparum (PV and PF), Brucella spp. (BR), dengue virus (DENV), Leishmania donovani (visceral leishmaniasis; VL), and Crimean-Congo hemorrhagic fever (CCHF) virus exposure among Afghan National Army (ANA) recruits. METHODS Randomly chosen, nationally representative serum(More)
BACKGROUND The World Health Organisation (WHO) recommends parasitological diagnosis of malaria before treatment, but use of malaria rapid diagnostic tests (mRDTs) by community health workers (CHWs) has not been fully tested within health services in south and central Asia. mRDTs could allow CHWs to diagnose malaria accurately, improving treatment of febrile(More)
