Abstract Background and Aims The substantial health challenges faced by patients on peritoneal dialysis (PD) or hemodialysis (HD) have increased considerably during the ongoing COVID-19 pandemic, but remain inadequately investigated. We therefore decided to compare perspectives of PD in-center HD their needs through this period with those healthcare professionals interviews both groups. Method ...

Download pose: To evaluate performances of published gene signatures for the assessment of urothelial oma. erimental Design: We evaluated 28 published gene signatures designed for diagnostic and progpurposes of urothelial cancer. The investigated signatures include eight signatures for stage, five for four for progression, and six for survival. We used two algorithms for classification, nearest...

The formation of cell protrusions such as lamellipodia and filopodia in motile cells is dependent on actin polymerization. The actin assembly takes place at the leading edge of the protrusions and is thought to provide the force for forward movement of the plasma membrane (for review see Mitchison and Cramer, 1996). In several cell types the actin meshwork moves in a retrograde manner from the ...

G-Frames in Hilbert spaces are a redundant set of operators which yield a representation for each vector in the space. In this paper we investigate the connection between g-frames, g-orthonormal bases and g-Riesz bases. We show that a family of bounded operators is a g-Bessel sequences if and only if the Gram matrix associated to its denes a bounded operator.

Avila and Molina [1] introduced the notion of generalized weak structures which naturally generalize minimal structures, generalized topologies and weak structures and the structures α(g),π(g),σ(g) and β(g). This work is a further investigation of generalized weak structures due to Avila and Molina. Further we introduce the structures ro(g) and rc(g) and study the properties of the structures r...
