Maf/ham1-like pyrophosphatases of non-canonical nucleotides are host-specific partners of viral RNA-dependent RNA polymerases.

Cassava brown streak disease (CBSD), dubbed the "Ebola of plants", is a serious threat to food security in Africa caused by two viruses of the family Potyviridae: cassava brown streak virus (CBSV) and Ugandan (U)CBSV. Intriguingly, U/CBSV, along with another member of this family and one secoviridae, are the only known RNA viruses encoding a protein of the Maf/ham1-like family, a group of widespread pyrophosphatase of non-canonical nucleotides (ITPase) expressed by all living organisms. Despite the socio-economic impact of CDSD, the relevance and role of this atypical viral factor has not been yet established.

New therapeutic approach to Tourette Syndrome in children based on a randomized placebo-controlled double-blind phase IV study of the effectiveness and safety of magnesium and vitamin B6.

Background: Tourette Syndrome (TS) is a neurological condition presenting chronic motor and phonic tics, and important degree of comorbidity. Considered an uncommon illness, it first becomes apparent during childhood. Current standard treatment only achieves partial control of the condition, and provokes frequent, and sometimes severe, side effects.

[An open study evaluating the efficacy and security of magnesium and vitamin B(6) as a treatment of Tourette syndrome in children].

Background And Objective: We intended to ascertain the effectiveness and safety of oral solutions of magnesium and vitamin B(6) in alleviating the symptoms emerged during clinical exacerbations in children aged 7-14 years suffering from Tourette syndrome (TS). We also aimed to determine the mean and the standard deviation of such an improvement in order to estimate sample sizes in future assays with a control group.

Patients And Method: The treatment under investigation was administered to children diagnosed with TS, in accordance with Diagnostic and Statistical Manual of Mental Disorders, fourth edition -IV, under conditions of clinical exacerbation.
