In this study, we demonstrated for the first time that besides the well-established post-transcriptional silencing based on mRNA degradation, miRNAs may be responsible for long-term latency of HIV-1 by TF, a different mechanism. We provide a possible molecular mechanism by which HIV-1 homologous miRNAs may impart resistance to HIV-1 and suggest a new miRNA-based therapeutic strategy for HIV-1.
This study evaluates the direct costs of treating asthma in Abu Dhabi in the United Arab Emirates. Data was compiled for 2011 from health insurance claims covering all medical interventions or treatments coded as asthma. Costs were calculated from a health care perspective. The total direct cost of treating 139,092 asthma patients was estimated to be United Arab Emirates Dirhams (AED) 105 million (US$29 million), corresponding to around AED 750 per patient per annum. The total cost is principally generated by outpatient visits (>AED 85 million; 81% of the total cost). Ten point four percent of patients had made an emergency room visit. The cost per visit seems to be higher during hospital admissions (AED 7,123) compared to outpatient visits and emergency room visits. The direct cost of asthma medications was around AED 33 million (31% of the total cost). The economic burden of asthma in Abu Dhabi is high and the number of emergency visits suggests that the disease is not optimally controlled.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
