In total hip arthroplasty (THA) for dysplastic hip osteoarthritis, bony deformity makes it difficult to identify the correct cup height and medialization. The authors developed a new technique for registration and navigation of cup position for dysplastic hips using an imageless navigation system. Eighty dysplastic hips (Crowe type I, n=58; type II, n=18; type III, n=4) underwent THA. Thirty-fo...

Autophagy is a physiological process for the recycling and degradation of cellular materials. Forming the autophagosome from the phagophore, a cup-shaped double-membrane vesicle, is a critical step in autophagy. The origin of the cup shape of the phagophore is poorly understood. In yeast, fusion of a small number of Atg9-containing vesicles is considered a key step in autophagosome biogenesis, ...

PURPOSE The optic cup is created through invagination of the optic vesicle. The morphogenetic rearrangement creates a double-layered cup, with a hinge (the Optic Cup Lip) where the epithelium bends back upon itself. Shortly after the optic cup forms, it is thought to be sub-divided into separate lineages: i) pigmented epithelium in the outer layer; ii) presumptive iris and ciliary body at the m...

PURPOSE It is challenging procedure to revise acetabular component in acetabulum with severe bone defect or deformity. The jumbo cup is good option for revisional arthroplasty in large bone defect. The purpose of this study is to compare the prognosis of revisional total hip arthroplasty using jumbo cup with peripheral rim fixation and no rim fixation. MATERIALS AND METHODS We included the pa...

Three movement procedures can combine nesting cups into seriated structures. Reliance on these procedures changes with age in human children, and the putatively most advanced emerges as a predominant procedure at 3 or more years. Six monkeys' (Cebus apella) combinatorial procedures and successes at nesting seriated cups were evaluated. The current study examined whether the procedures used (a) ...

Three types of commercially available ultra-high molecular weight polyethylene (UHMWPE) acetabular cups currently used in total hip arthroplasty have been studied by means of Raman micro-spectroscopy to unfold the microstructural modification induced by the oxidative degradation after accelerated aging with and without lipid absorption. The three investigated materials were produced by three di...

Forming complex sheet products using hydrostatic forming technology is currently a focus of the majority processes. However, in order to increase stability during process, it necessary identify and analyze dependency pressure quality product on input parameters. For purpose modeling pressure, this paper presents empirical research cylindrical cup made various materials, including carbon steel (...

The success and efficiency of wall-climbing robots is not only a question of closed-loop control and electronics. Also materials have a large influence on the operability to make the systems light-weighted or more robust. This paper presents findings based on experiments to find an optimal material for inflatable adaptive sealings. Demands of such sliding sealings are robustness and good slidin...

Blue crab processors need packaging options for fresh and pasteurized crab meat that reduce processing and packaging costs, improve quality, safety, and shelf life, and accommodate smaller portion sizes. Traditional fresh and pasteurized crab meat containers are 16 oz polyethylene cups and 16 oz steel cans, respectively. Processors have been presented with a number of new commercial options for...
