Background: Muscle proteins of the obscurin protein family play important roles in sarcomere organization and sarcoplasmic reticulum and T-tubule architecture and function. However, their precise molecular functions and redundancies between protein family members as well as their involvement in cardiac diseases remain to be fully understood.
Methods: To investigate the functional roles of Obsc (obscurin) and its close homolog Obsl1 (obscurin-like 1) in the heart, we generated and analyzed knockout mice for , , as well as double knockouts.
The chirality of helical polypeptides is correlated to that of their constituent amino acid residues. For polypeptides with non-natural backbones, however, such correlations are less clear. Here, circular double helices with torus knot/link topologies were assembled from non-natural metal-peptide chains composed of Ag(I) ions and ditopic tripeptides with Gly-Gly-Ala and Gly-Ala-Gly sequences.

Furthermore, balloon-expandable transcatheter aortic valve replacement is associated with an increased risk of annular rupture, and self-expandable transcatheter aortic valve replacement is associated with worse post-operative residual paravalvular leakage grades. Therefore, developing an optimal method for transcatheter aortic valve replacement for patients with left ventricular outflow tract calcification is desirable.
View Article and Find Full Text PDFBackground And Purpose: The cortical high-flow sign has been more commonly reported in oligodendroglioma, IDH-mutant and 1p/19q-codeleted (ODG IDHm-codel) compared to diffuse glioma with IDH-wildtype or astrocytoma, IDH-mutant. Besides tumor types, higher grades of glioma might also contribute to the cortical high flow. Therefore, we investigated whether the histological cortical vascular density or CNS WHO grade was associated with the cortical high-flow sign in patients with ODG IDHm-codel.
