BACKGROUND Within the lateral pillar classification of the Legg-Calvé-Perthes (LCP) disease, hips seem quite variable in the pattern of fragmentation as seen in radiographs. The purpose of this study was to determine: if it is possible to reliably subdivide the lateral pillar groups into femoral head fragmentation patterns, and if such a subdivision of the lateral pillar groupings is clinically...

By observing gill blood flow using epi-illuminating microscopy, in parallel with cardiovascular recordings and immunohistochemistry, we have tried to identify the receptor mediating endothelin (ET) type 1 (ET1)-induced pillar cell contraction in the lamellae of the Atlantic cod (Gadus morhua). Intra-arterial injection of the specific ET(B) receptor agonist BQ-3020 induced dose-dependent increas...

A kind of novel pillar (used to support a windshield) has been designed to replace the conventional ones used in all sorts of vehicles. The prominent advantage of such a pillar is that it appears invisible so that the blind spots caused by A, B, C and D pillars will be diminished to a large extent or even eliminated completely. Therefore, the driver’s view is enlarged considerably. An intrinsic...

Background and purpose - Different radiographic classifications have been proposed for prediction of outcome in Perthes disease. We assessed whether the modified lateral pillar classification would provide more reliable interobserver agreement and prognostic value compared with the original lateral pillar classification and the Catterall classification. Patients and methods - 42 patients (38 bo...

BACKGROUND Accurate and reliable radiographic classifications of the relative severity and outcome of Legg-Calve-Perthes disease are essential in the study of that disease. As part of a prospective multicenter study, we sought to define more clearly the lateral pillar classification of severity and the Stulberg classification of outcome; we sought especially to define the borderlines between cl...

This is a retrospective observational study. Greater trochanteric epiphysiodesis (GTE) has been recommended to prevent Trendelenburg gait and limitation of the hip joint motion due to trochanteric overgrowth after femoral varus osteotomy (FVO) in Legg-Calvé-Perthes disease (LCPD). However, capital femoral physeal arrest frequently occurs in patients with severe disease (lateral pillar C), so GT...

The collapse of abandoned room-and-pillar mines is often violent and unpredictable. Safety concerns often resulted in mine closures with no post-mining stability evaluations. As a result, large amounts of land resources over room-and-pillar mines are wasted. This paper attempts to establish an understanding of the long-term stability issues of goafs (abandoned mines). Considering progressive pi...

Germanium is one of the promising alloying anode (Si, Ge, Sn) materials for high capacity lithium ion batteries. Since it is isostructural with crystalline silicon, crystalline Ge is expected to show intriguing lithiation-induced phenomena similar to Si, such as anomalous volume expansion and fracture. Here, we present the study of lithiation of Ge micropillars, andwe compare the findings to si...

Anti-adhesive glycoclusters offer potential as therapeutic alternatives to classical antibiotics in treating infections. Pillar[5]arenes functionalised with either five galactose or five fucose residues were readily prepared using CuAAC reactions and evaluated for their binding to three therapeutically relevant bacterial lectins: LecA and Lec B from Pseudomonas aeuruginosa and BambL from Burkho...
