ALICE is the heavy-ion experiment at the CERN Large Hadron Collider. The experiment continuously took data during the first physics campaign of the machine from fall 2009 until early 2013, using proton and lead-ion beams. In this paper we describe the running environment and the data handling procedures, and discuss the performance of the ALICE detectors and analysis methods for various physics observables.
The benefit of performing ultrasonography and scintigraphy in the acute phase or cystourethrography is minimal. Our findings support (1) technetium-99m-dimercaptosuccinic acid scintigraphy 6 months after infection to detect scarring that may be related to long-term hypertension, proteinuria, and renal function impairment (although the degree of scarring was generally minor and did not impair renal function) and (2) continued surveillance to identify recurrent urinary tract infections that may warrant further investigation.
Some children with congenital solitary kidney show decreased glomerular filtration rate. Associated anomalies of the kidney/urinary tract and insufficient renal length appear to be significant risk factors. Adequate length of the congenital solitary kidney is a key parameter for maintenance of renal function and should be examined routinely during followup.
Thirty-seven prepubertal children evaluated for severe growth retardation were studied by assessment of total granulocyte, monocyte and lymphocyte count, lymphocyte subsets CD3+, CD3+Dr+, CD3+Dr-, CD4+, CD8+, CD8+CD57+, CD8+CD57-, CD16+, CD20+ and CD23+, serum immunoglobulin concentrations, and phagocytic activity of circulating neutrophils and monocytes (by a flow cytometric assay). Idiopathic GH deficiency was diagnosed in 21 of 37 patients; the remaining 16 healthy subjects served as controls. Fourteen patients received biosynthetic GH (rhGH), and their immune parameters were assessed at baseline and after 6 months of therapy. Phagocytic function mediated by both polymorphonuclears and monocytes was significantly impaired in GH-deficient subjects compared to controls (p < 0.003 for neutrophils, p < 0.007 for monocytes), while a significant increase of phagocytic activity was obtained during long-term rhGH replacement therapy (p < 0.02 for neutrophils, p < 0.001 for monocytes), thus suggesting that GH may affect the functional activity of circulating phagocyte cells. No significant differences were found in total granulocyte, monocyte and lymphocyte counts, T- and B-lymphocyte subsets and immunoglobulin levels, between GH-deficient patients and controls, and between values observed before and during rhGH substitution treatment.
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.
