Elevated uric acid levels, mortality and cognitive impairment in children with severe malaria.

We investigated the role of uric acid in the pathogenesis of severe malaria (SM) in two independent cohorts of children with SM. Hyperuricemia (blood uric acid ≥ 7 mg dl) was present in 25% of children with SM and was associated with increased in-hospital mortality and postdischarge mortality in both cohorts. Increased blood uric acid levels were also associated with worse scores in overall cognition in children with SM < 5 years old in both cohorts.

Immunofluorescence laser micro-dissection of specific nephron segments in the mouse kidney allows targeted downstream proteomic analysis.

Laser micro-dissection (LMD) is a very useful tool that allows the isolation of finite areas from tissue specimens for downstream analysis of RNA and protein. Although LMD has been adapted for use in kidney tissue, the use of this powerful tool has been limited by the diminished ability to identify specific tubular segments in the kidney. In this study, we describe a major improvement in the methodology to isolate specific cells in the mouse kidney using immunofluorescence LMD (IF-LMD).
