Seroprevalence of canine distemper virus antibodies in free-roaming dogs in Cambodia.

Canine distemper virus (CDV) can infect a wide range of mammalian carnivores and can cause severe illness and death. Domestic dogs may be an important source of this virus for endangered wild carnivores. The objective of this study was to establish the presence of CDV in rural areas of Cambodia bordering three established protected habitats, and to determine the seroprevalence of CDV in free-roaming dogs inhabiting these areas.

Prognostic role of extent of resection and adjuvant radiotherapy in de novo anaplastic meningiomas.

Purpose: Grade 3 meningiomas, although rare, are associated with high morbidity and mortality. The respective impacts of extent of surgical resection and adjuvant radiotherapy are still debated. Moreover, anaplastic meningiomas are studied in heterogenous cohort of de novo and progressive anaplastic tumors.

Synthesis, in vitro and in vivo biological evaluation of novel dual compounds targeting both acetylcholinesterase and serotonergic 5-HT receptors with potential interest in the treatment of Alzheimer's disease.

In this work, we exemplified the "copride" family of drug candidates able to both inhibit acetylcholinesterase and to activate 5-HT receptors, with anti-amnesiant and promnesiant activities in mice. Twenty-one analogs of donecopride, the first-in class representative of the series, were synthesized exploring the influence on the biological activities of the substituents (methoxy, amine and chlorine) carried by its phenyl ring. This work was the support of an intensive structure-activity relationship study and allowed to obtain some interesting derivatives of donecopride.

Azithromycin disrupts apicoplast biogenesis in replicating and dormant liver stages of the relapsing malaria parasites Plasmodium vivax and Plasmodium cynomolgi.

The control and elimination of malaria caused by Plasmodium vivax is hampered by the threat of relapsed infection resulting from the activation of dormant hepatic hypnozoites. Currently, only the 8-aminoquinolines, primaquine and tafenoquine, have been approved for the elimination of hypnozoites, although their use is hampered by potential toxicity. Therefore, an alternative radical curative drug that safely eliminates hypnozoites is a pressing need.
