Wnt/β-catenin signaling plays a central role in development and is also involved in a diverse array of diseases. β-Catenin activity is tightly regulated via a multiprotein complex that includes the kinase glycogen synthase kinase-3β (GSK-3β). GSK-3β phosphorylates β-catenin, marking it for ubiquitination and degradation via the proteasome. Thus in regulation of the Wnt pathway, the ubiquitin sy...
This trial aimed to compare the dialysis complications occurring during different durations of extended daily dialysis (EDD) sessions in critically ill AKI patients. We included patients older than 18 years with AKI associated with sepsis admitted to the intensive care unit and using noradrenaline dose ranging from 0.3 to 0.7 μg/kg/min. Patients were divided into two groups randomly: in G1, 6 h...
We explored the application of electron detachment dissociation (EDD) and infrared multiphoton dissociation (IRMPD) tandem mass spectrometry to fluorescently labeled sialylated oligosaccharides. Standard sialylated oligosaccharides and a sialylated N-linked glycan released from human transferrin were investigated. EDD yielded extensive glycosidic cleavages and cross-ring cleavages in all cases ...
This paper presents a method for estimating the orientation of planar text surfaces using the edge-direction distribution (EDD) extracted from the image as input to a neural network. We consider canonical rotations and we developed a mathematical model to analyze how the EDD changes with the rotation angle under orthographic projection. In order to improve performance and solve quadrant ambigui...
In Wireless ATM networks transmission resources are shared among geographically disperse applications with diverse Quality of Service (QoS) requirements and traac characteristics. To provide QoS guarantees and use the bandwidth eeciently, call admission and scheduling functions are necessary. These functions should ensure the delivery of the target QoS to the supported applications while achiev...
Electron detachment dissociation (EDD) Fourier transform mass spectrometry has recently been shown to be a useful method for tandem mass spectrometry analysis of sulfated glycosaminoglycans (GAGs). EDD produces abundant glycosidic and cross-ring fragmentations that are useful for localizing sites of sulfation in GAG oligosaccharides. Although EDD fragmentation can be used to characterize GAGs i...
Reductions in arterial SIRT1 expression and activity with aging are linked to vascular endothelial dysfunction. We tested the hypothesis that the specific SIRT1 activator SRT1720 improves endothelial function [endothelium-dependent dilation (EDD)] in old mice. Young (4-9 mo) and old (29-32 mo) male B6D2F1 mice treated with SRT1720 (100 mg/kg body wt) or vehicle for 4 wk were studied with a grou...
