We study the feedback group action on multi-input nonlinear control systems with uncontrollable mode. We follow slightly an approach proposed in Kang and Krener [W. Kang and A. J. Krener, SIAM J. Control. Optim., 30 (1992), pp. 1319–1337] which consists of analyzing the system and the feedback group step by step. We construct a normal form which generalizes, on one hand, the results obtained in...

Based on the protein sequence deduced from a cDNA clone, it has been proposed that the maize bt1 locus encodes an amyloplast membrane metabolite translocator protein (Sullivan, T. D., Strelow, L. I., Illingworth, C. A., Phillips, R. L., and Nelson, O. E., Jr. (1991) Plant Cell 3, 1337-1348). The present work provides further evidence for this hypothesis by showing that the gene product of Bt1 c...

RATIONALE Integrins cooperate with growth factor receptors to promote downstream signaling for cell proliferation and migration. However, the mechanism of receptor activation is still unknown. OBJECTIVE To analyze the mechanism of phosphorylation of the vascular endothelial growth factor receptor (VEGFR)-3 by cell adhesion. METHODS AND RESULTS We show that VEGFR-3 phosphorylation, induced b...

Taking multiple-choice practice tests with competitive incorrect alternatives can enhance performance on related but different questions appearing on a later cued-recall test (Little et al., Psychol Sci 23:1337-1344, 2012). This benefit of multiple-choice testing, which does not occur when the practice test is a cued-recall test, appears attributable to participants attempting to retrieve not o...

INTRODUCTION In recent decades, new high-performance prostheses have been invented for use with small aortic annuli, and they have helped avoid patient prosthesis mismatch (PPM) without the need for aortic annular enlargement. The purpose of this study is to examine the trends in mechanical aortic valve replacement surgery in a large, multi-surgeon, single hospital practice. MATERIAL AND METH...

The aim of this chart review was to obtain an objective, quantitative assessment of the clinical performance of an implant line used in an implantological office setting. Implants with hydrophilic (INICELL) and hydrophobic (TST; both: Thommen Medical AG, Grenchen, Switzerland) enossal surfaces were compared and the cumulative implant survival rate was calculated. The data of 1063 patients that ...

Recent epidemiological evidence suggests that there are two forms of Crohn disease (CD): perforating and nonperforating. We hypothesized that, just as with tuberculoid and lepromatous leprosy, differences in the two forms of CD would be both identified and determined by differences in the host immune response. Resected intestinal tissue from control patients as well as perforating and nonperfor...

Synapsin I (protein I) is a neuron-specific phosphoprotein, which is a substrate for cAMP-dependent and Ca/calmodulin-dependent protein kinases. In two accompanying studies (De Camilli, P., R. Cameron, and P. Greengard, and De Camilli, P., S. M. Harris, Jr., W. B. Huttner, and P. Greengard, 1983, J. Cell Biol. 96:1337-1354 and 1355-1373) we have shown, by immunocytochemical techniques at the li...

Hexaploid wheat displays limited genetic variation. As a direct A and B genome donor of hexaploid wheat, tetraploid wheat represents an important gene pool for cultivated bread wheat. Many disease resistant genes express conserved domains of the nucleotide-binding site and leucine-rich repeats (NBS-LRR). In this study, we isolated a CC-NBS-LRR gene locating on chromosome 7B from durum wheat var...
