BACKGROUND Achieving a balanced and proper nutrition is one of the most important health objectives in the early years of the child's life. The aim of this study is to determine the level of knowledge and attitude of the mothers covered by the urban health centers of Birjand about nutritional behaviors. MATERIALS AND METHODS This descriptive-analytical study was conducted on the mothers with ...
Confidence intervals for parameters that can be arbitrarily close to being unidentified are unbounded with positive probability (e.g. Dufour, Econometrica 65, pp. 1365-1387 and Pfanzagl, Journal of Statistical Planning and Inference, 75, pp. 9-20), and the asymptotic risks of their estimators are unbounded (Pötscher, Econometrica 70, pp. 1035-1065). We extend these “impossibility results” and s...
Objective quality assessment methods have been used widely for evaluation of audio coding systems. However, even though many different competing multi-channel audio compression coding systems are being developed, most current quality assessment methods only predict results for monaural or stereo signals. In this paper, a prediction method is introduced that can be used for multi-channel audio c...
Burrowing, an ethologically relevant rodent behaviour, has been proposed as a novel outcome measure to assess the global impact of pain in rats. In a prospective multicentre study using male rats (Wistar, Sprague-Dawley), replication of suppressed burrowing behaviour in the complete Freund adjuvant (CFA)-induced model of inflammatory pain (unilateral, 1 mg/mL in 100 µL) was evaluated in 11 stud...
Recessive mutations of sulfonylurea receptor 1 (SUR1) and potassium inward rectifier 6.2 (Kir6.2), the two adjacent genes on chromosome 11p that comprise the beta-cell plasma membrane ATP-sensitive K(+) (K(ATP)) channels, are responsible for the most common form of congenital hyperinsulinism in children. The present study was undertaken to identify the genetic defect in a family with dominantly...
tion improves erythropoiesis-stimulating agent (ESA) resistance in comparison with low-flux bicarbonate dialysis: results of the REDERT study. Nephrol Dial Transplant 2015; 30: 682–689 10. Young B, Zaritsky J. Hepcidin for clinicians. Clin J Am Soc Nephrol 2009; 4: 1384–1387 11. Adamson JW. Hyporesponsiveness to erythropoiesis stimulating agents in chronic kidney disease: the many faces of infl...

The effect of typical membrane processing conditions on the structure, interfacial morphology, and gas separation performance of MOF/polymer nanocomposite membranes is investigated. In particular, the ZIF...
N Engl J Med 2006;354:1387-401. Copyright © 2006 Massachusetts Medical Society. The inherited forms of proteinuria comprise a heterogeneous group of rare renal diseases in which glomerular dysfunction and proteinuria are prominent. Despite the rarity of hereditary proteinuria syndromes, genetic, biochemical, and structural studies of these diseases have made important contributions to our knowl...
Polymerization of actin proteins into dynamic structures is essential to eukaryotic cell life, motivating many in vitro experiments measuring polymerization kinetics of individual filaments. Here, we model these kinetics, accounting for all relevant steps revealed by experiment: polymerization, depolymerization, random ATP hydrolysis, and release of phosphate (P(i)). We relate filament growth r...
Evidence of an inorganic carbon concentrating system in a marine macroalga is provided here. Based on an O(2) technique, supported by determinations of inorganic carbon concentrations, of experimental media (as well as compensation points) using infrared gas analysis, it was found that Ulva fasciata maintained intracellular inorganic carbon levels of 2.3 to 6.0 millimolar at bulk medium concent...
