We show that every connected induced subgraph of a graph G is dominated by an split if and only C-free, where C set six graphs which includes P7 C7, each containing P5. A similar characterization shown for the class are complete graph. Motivated these results, we study structural descriptions some classes (P7, C7)-free graphs. In particular, give C4, gem)-free diamond)-free Using satisfies χ(G)...

A technique for obtaining dipolar-mediated INADEQUATE NMR spectra with a large spectral window in the double-quantum dimension is presented. Using the dipolar recoupling sequence C7 to excite the double-quantum coherence under magic-angle spinning, the technique involves incrementing the evolution period in synchrony with the phase of the radiofrequency pulses in the C7 sequence. The technique ...

The double crush hypothesis has not been rigorously evaluated in humans. We therefore analyzed cases of C6, C7, and C8 radiculopathy and exploited the fact that the median sensory response is of C6/C7 origin and the median motor response is primarily of C8 origin. We hypothesized that C6 and/or C7 cases would demonstrate an increased frequency of median mononeuropathy by sensory criteria, and C...

Normally the 7th cervical vertebra (C7) has a long non-bifid spine. A bifid spine is a feature of typical cervical vertebrae such as C3--C6. In contrast to past studies, which have described a bifid spine in the C3--C6 cervical vertebrae, this study is a report on the presence of a duplicated spinous process in the C7 vertebra with an intervening space. The presence of such anomalies may be ass...

R(C4, K4) = 10 (see [2]) R(C4, K5) = 14 (see [3]) R(C5, K4) = 13, R(C5, K5) = 17 (see [5, 6]) R(Cn, K3) = 2n − 1 (n > 3) (see [4, 7]). In [10], we proved that R(Cn, K4) = 3(n − 1) + 1 (n ≥ 4). In this paper, we will prove that R(Cn, K5) = 4(n − 1)+ 1 (n = 6, 7). The following notations will be used in this paper. If G is a graph, the vertex set (resp. edge set) of G is denoted by V (G) (resp. E...

In 1959, Grötzsch [5] famously proved that every planar graph of girth at least 4 is 3-colourable (or equivalently, admits a homomorphism to C3). A natural generalization this the following conjecture: for positive integer t, 4t C2t+1. This in fact dual well-known conjecture Jaeger [7] which states 4t-edge-connected modulo (2t + 1)-orientation. Though Jaeger’s original was disproved [6], Lovász...

BACKGROUND CONTEXT Some postoperative complications after anterior cervical fusions have been attributed to anterior cervical plate (ACP) profiles and the necessary wide operative exposure for their insertion. Consequently, low-profile stand-alone interbody spacers with integrated screws (SIS) have been developed. Although SIS constructs have demonstrated similar biomechanical stability to the ...

We describe a novel localization of C7 as a membrane-bound molecule on endothelial cells (ECs). Data obtained by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), Western blot analysis, Northern blot analysis, and mass spectrometry revealed that membrane-associated C7 (mC7) was indistinguishable from soluble C7 and was associated with vimentin on the cell surface. mC7 intera...

Glucocorticoid (GC)-evoked apoptosis of T-lymphoid cells is preceded by increases in the intracellular Ca2+ concentration ([Ca2+]i), which may contribute to apoptosis. This report demonstrates that GC-mediated upregulation of the bZIP transcriptional repressor gene, E4BP4, is dependent on [Ca2+]i levels, and correlates with GC-evoked apoptosis of GC-sensitive CEM-C7-14 cells. Calcium chelators ...
