In a graphG= (V ,E) of order n and maximum degree , a subset S of vertices is a k-independent set if the subgraph induced by S has maximum degree less or equal to k − 1. The lower k-independence number ik (G) is the minimum cardinality of a maximal k-independent set in G and the k-independence number k(G) is the maximum cardinality of a k-independent set. We show that ik n − + k − 1 for any gra...

AIM To compare the efficacy of using covered self-expandable metal stents (CSEMSs) and uncovered self-expandable metal stents (UCSEMSs) to treat objective jaundice caused by an unresectable malignant tumor. METHODS We performed a comprehensive electronic search from 1980 to May 2015. All randomized controlled trials comparing the use of CSEMSs and UCSEMSs to treat malignant distal biliary obs...

BACKGROUND Two pertussis toxin sensitive G(i) proteins, G(i2) and G(i3), are expressed in cardiomyocytes and upregulated in heart failure. It has been proposed that the highly homologous G(i) isoforms are functionally distinct. To test for isoform-specific functions of G(i) proteins, we examined their role in the regulation of cardiac L-type voltage-dependent calcium channels (L-VDCC). METHOD...

In this paper we study the concepts of I-Cauchy and I∗-Cauchy for double sequences in a linear metric space. Also, we give the relation between I-convergence and I∗-convergence of double sequences of functions defined between linear metric spaces.

Abstract Aim Fragility ankle fractures are traditionally managed conservatively or with open reduction internal fixation (ORIF). Tibiotalocalcaneal (TTC) nailing is an alternative option for the geriatric patient. This meta-analysis provides most detailed analysis of hindfoot fragility fractures. Method A systematic search was performed on MEDLINE, EMBASE, Cochrane Library, Scopus, Web Science,...

We provide indirect evidence that six axonemal proteins here referred to as "dynein regulatory complex" (drc) are located in close proximity with the inner dynein arms I2 and I3. Subsets of drc subunits are missing from five second-site suppressors, pf2, pf3, suppf3, suppf4, and suppf5, that restore flagellar motility but not radial spoke structure of radial spoke mutants. The absence of drc co...

Abstract Background Myocardial deposition of amyloid proteins results in restrictive cardiomyopathy. Left ventricular global longitudinal strain (GLS) has emerged as a sensitive measure for detecting subclinical cardiac dysfunction over traditional echocardiographic parameters. However, multiple studies have provided differing conclusions regarding prognostic utility impaired GLS patients with ...
