OBJECTIVES This study was directed at developing spatial 62-lead electrocardiogram (ECG) criteria for classification of counterclockwise (CCW) and clockwise (CW) typical atrial flutter (Fl) in patients with and without structural heart disease. BACKGROUND Electrocardiographic classification of CCW and CW typical atrial Fl is frequently hampered by inaccurate and inconclusive scalar waveform a...

Activation of the mitogen-activated protein (MAP) kinase pathway has been associated with both cell proliferation and differentiation. Constitutively activated forms of Mek (MAP kinase/Erk kinase) and Erk (MAP kinase) have been previously shown capable of inducing differentiation or proliferation in nonhematopoietic cells. To specifically examine the role of Erk activation in megakaryocytic gro...

BACKGROUND Previous experimental work using in situ zymography has shown very early increased plasminogen activation in ischemic regions after 3 h of ischemia with and without reperfusion. The objective of the present study was to evaluate the time course and extent of plasminogen activation in long-term permanent focal cerebral ischemia. MATERIAL AND METHODS The middle cerebral artery in mal...

Several serine/threonine and tyrosine kinase signal transduction pathways have been recently linked to prolactin (PRL) action in lymphoid cells. Utilizing the lactogen-dependent, rat pre-T lymphoma cell line, Nb2-11, and the autonomous subline, Nb2-SFJCD1, studies were conducted to determine whether PRL- or interleukin-2 (IL-2)-stimulated Nb2 cell proliferation is coupled to the activation of p...

Due to the black-box nature of deep learning models, there is a recent development solutions for visual explanations CNNs. Given high cost user studies, metrics are necessary compare and evaluate these different methods. In this paper, we critically analyze Deletion Area Under Curve (DAUC) Insertion (IAUC) proposed by Petsiuk et al. (2018). These were designed faithfulness saliency maps generat...

Phospholipase D (PLD) activity is regulated by phosphatidylinositol 4,5-biphosphate, protein kinase C (PKC), ADP-ribosylation factor, and Rho. The present study was designed to investigate the mechanism of norepinephrine (NE)-mediated PLD activation in rabbit aortic vascular smooth muscle cells (VSMC). NE (10 microM) caused activation of PLD, as measured by the production of phosphatidylethanol...

To study the function of the farnesyl modification of Ras, the farnesyl group and a variety of its structural analogs, which lack one or more double bonds and/or the methyl groups, were enzymatically incorporated into recombinant H-Ras in vitro. These proteins were used in a cell- and membrane-free, Ras-dependent mitogen-activated protein kinase (MAP kinase) activation system derived from Xenop...
