Three thousand consecutive muscle biopsies were reviewed for the presence of tubular aggregates and their association with clinical symptomatology. Tubular aggregates were detected in 19 patients (0.6%). Twelve of these nineteen patients had severe myalgia, and the most abundant tubular aggregates were found in biopsies of patients with myalgia. Seven patients had only myalgia as their clinical...

IN THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: 2,2'-dimethyl-4,4'-(3,10-dithia-tricyclo-[10.2.2.2(5,8)]octa-deca-1(14),5,7,12,15,17-hexaen-6,17-di-yl)dibut-3-yn-2-ol], C(26)H(28)O(2)S(2), mol-ecules are linked by O-H⋯O hydrogen bonds, forming a tubular chain which runs parallel to the b axis. The tubular structure is reinforced by π-π stacking inter-actions [centroid-centroid ...

All artificial nerve grafts have a tubular structure, and they guide axonal regrowth through the tube from the proximal side toward the peripheral side. Based on the results of our experimental study using animals, we used alginate gel without a tubular structure as an artificial nerve graft for digital nerve repair and evaluated peripheral nerve regeneration. In 2 patients, a gap due to digita...

The versatility of the textile weaving process has made it a popular method for producing structural composite preforms. Enhanced through-thickness strength by multi-layer weaving, good in-plane strength and the ability to produce 2.5D or 3D shapes, are some of the advantages which have made weaving the most commonly used textile process for composite applications. It is also possible to incorp...

1. Abstract This paper focuses on improvement of the crashworthiness of tubular structures using compliant mechanism approach to intelligently tailor local mechanical properties throughout the structure. The ideal crashworthy performance for energy absorbing tubular structures can be achieved by promoting progressive buckling throughout the length of the tube to occur. Progressive buckling is t...

Abstract Tubular structure enhancement plays an utmost role in medical image segmentation as a pre-processing technique. In this work, unsupervised 3D tubular technique is developed, which mainly inspired by the idea of filter combination. Three well-known vessel filters, Frangi’s filter, modified and Multiscale Fractional Anisotropic Tensor (MFAT) separately enhance original images. Next, enha...
