    Ebola virus is notorious for causing severe and even deadly haemorrhagic fever in infected humans and non-human primates. The high fatality rate of Ebola virus disease (EVD) has highlighted the need for effective diagnosis and treatment. Two monoclonal antibodies (mAbs) have been approved by USFDA for treatment of EVD. Virus surface glycoprotein is the common target for diagnostic and therapy including vaccines. Even so, VP35, a viral RNA polymerase cofactor and interferon inhibitor could be a potential target to curb EVD. The present work describes the isolation of three mAb clones from a phage-displayed human naïve scFv library against recombinant VP35. The clones showed binding against rVP35 in vitro and inhibition of VP35 in luciferase reporter gene assay. Structural modelling analysis was also carried out to identify the binding interactions involved in the antibody-antigen interaction model. This allows some insight into the "fitness" of the binding pocket between the paratope and target epitope which would be useful for the design of new mAbs through in silico means in the future. In conclusion, the information obtained from the 3 isolated mAbs could be potentially useful in the quest to improve VP35 targeting for therapeutic development in the future.

    The burden of premature death and health loss from ESRD is well described. Less is known regarding the burden of cardiovascular disease attributable to reduced GFR. We estimated the prevalence of reduced GFR categories 3, 4, and 5 (not on RRT) for 188 countries at six time points from 1990 to 2013. Relative risks of cardiovascular outcomes by three categories of reduced GFR were calculated by pooled random effects meta-analysis. Results are presented as deaths for outcomes of cardiovascular disease and ESRD and as disability-adjusted life years for outcomes of cardiovascular disease, GFR categories 3, 4, and 5, and ESRD. In 2013, reduced GFR was associated with 4% of deaths worldwide, or 2.2 million deaths (95% uncertainty interval [95% UI], 2.0 to 2.4 million). More than half of these attributable deaths were cardiovascular deaths (1.2 million; 95% UI, 1.1 to 1.4 million), whereas 0.96 million (95% UI, 0.81 to 1.0 million) were ESRD-related deaths. Compared with metabolic risk factors, reduced GFR ranked below high systolic BP, high body mass index, and high fasting plasma glucose, and similarly with high total cholesterol as a risk factor for disability-adjusted life years in both developed and developing world regions. In conclusion, by 2013, cardiovascular deaths attributed to reduced GFR outnumbered ESRD deaths throughout the world. Studies are needed to evaluate the benefit of early detection of CKD and treatment to decrease these deaths.
