Input: Consider Input: Podocalyxin is the major sialoprotein in the glycocalyx of glomerular podocytes. Here we report on its extraglomerular localization, using a monospecific antibody which was obtained by affinity purification of IgG on nitrocellulose transfers of glomerular podocalyxin. By indirect immunofluorescence, podocalyxin was found in the blood vessels of several organs (lung, heart, kidney, small intestine, brain, pancreas, aorta, the periportal blood vessels in liver, and the central arteries of follicles of the spleen, but not in the endothelia that line the sinusoids of the latter organs). By immunoelectron microscopy--using immunogold conjugates in diffusion ("pre-embedding") and surface ("postembedding") procedures--podocalyxin was localized on the luminal membrane domain of endothelial cells, in a patchy distribution. The presence of podocalyxin was confirmed in SDS extracts of lung tissue by immunoblotting. We conclude that (a) podocalyxin is a widespread component of endothelial plasma membranes, (b) it is restricted to the luminal membrane domain, and (c) it is distributed unevenly on the endothelial cell surface.

Output: Endothelial cell membranes contain podocalyxin--the major sialoprotein of visceral glomerular epithelial cells

Input: Consider Input: Amino acids control cell growth via activation of the highly conserved kinase TORC1. Glutamine is a particularly important amino acid in cell growth control and metabolism. However, the role of glutamine in TORC1 activation remains poorly defined. Glutamine is metabolized through glutaminolysis to produce -ketoglutarate. We demonstrate that glutamine in combination with leucine activates mammalian TORC1 (mTORC1) by enhancing glutaminolysis and -ketoglutarate production. Inhibition of glutaminolysis prevented GTP loading of RagB and lysosomal translocation and subsequent activation of mTORC1. Constitutively active Rag heterodimer activated mTORC1 in the absence of glutaminolysis. Conversely, enhanced glutaminolysis or a cell-permeable -ketoglutarate analog stimulated lysosomal translocation and activation of mTORC1. Finally, cell growth and autophagy, two processes controlled by mTORC1, were regulated by glutaminolysis. Thus, mTORC1 senses and is activated by glutamine and leucine via glutaminolysis and -ketoglutarate production upstream of Rag. This may provide an explanation for glutamine addiction in cancer cells.

Output: Glutaminolysis activates Rag-mTORC1 signaling.

Input: Consider Input: BACKGROUND Acute renal failure is a common complication of severe malaria in adults, and without renal replacement therapy (RRT), it carries a poor prognosis. Even when RRT is available, delaying its initiation may increase mortality. Earlier identification of patients who will need RRT may improve outcomes.
METHOD Prospectively collected data from two intervention studies in adults with severe malaria were analysed focusing on laboratory features on presentation and their association with a later requirement for RRT. In particular, laboratory indices of acute tubular necrosis (ATN) and acute kidney injury (AKI) that are used in other settings were examined.
RESULTS Data from 163 patients were available for analysis. Whether or not the patients should have received RRT (a retrospective assessment determined by three independent reviewers) was used as the reference. Forty-three (26.4%) patients met criteria for dialysis, but only 19 (44.2%) were able to receive this intervention due to the limited availability of RRT. Patients with impaired renal function on admission (creatinine clearance < 60 ml/min) (n = 84) had their laboratory indices of ATN/AKI analysed. The plasma creatinine level had the greatest area under the ROC curve (AUC): 0.83 (95% confidence interval 0.74-0.92), significantly better than the AUCs for, urinary sodium level, the urea to creatinine ratio (UCR), the fractional excretion of urea (FeUN) and the urinary neutrophil gelatinase-associated lipocalcin (NGAL) level. The AUC for plasma creatinine was also greater than the AUC for blood urea nitrogen level, the fractional excretion of sodium (FeNa), the renal failure index (RFI), the urinary osmolality, the urine to plasma creatinine ratio (UPCR) and the creatinine clearance, although the difference for these variables did not reach statistical significance.
CONCLUSIONS In adult patients with severe malaria and impaired renal function on admission, none of the evaluated laboratory indices was superior to the plasma creatinine level when used to predict a later requirement for renal replacement therapy.
Output: Laboratory prediction of the requirement for renal replacement in acute falciparum malaria
