Evidence For Decoupled Water Potential Between Myco- And Photobionts During Desiccation In The Tripartite Lichen Peltigera britannica.

In lichens, accurate description of thallus water status is required to understand growth and photosynthesis dynamics. A recent model suggested that myco- and photobiont layers could have a different water energy status (i.e.

Renal Functional Reserve in Naïve HIV Patients.

Renal functional reserve (RFR) is the kidney capability of increasing its basal glomerular filtration rate (GFR) at least 20% after an adequate stimulus. Renal disorders have been reported in seropositive HIV patients, particularly the decrease in glomerular filtration rate (eGFR), nephrotic syndrome, and proximal tubular deficiency associated with the disease itself or the use of some anti-retroviral treatments. Thus, it was decided to carry out a prospective study in order to evaluate if RFR test was preserved in naive HIV patients.

The RNA-binding protein EIF4A3 promotes axon development by direct control of the cytoskeleton.

The exon junction complex (EJC), nucleated by EIF4A3, is indispensable for mRNA fate and function throughout eukaryotes. We discover that EIF4A3 directly controls microtubules, independent of RNA, which is critical for neural wiring. While neuronal survival in the developing mouse cerebral cortex depends upon an intact EJC, axonal tract development requires only Eif4a3.
