Purpose and hypothesis: Acromion spur is the extrinsic factor for impingement syndrome and rotator cuff tear. The Rockwood tilt view can be used to evaluate prominence of the anterior acromion, however no study has shown the correlation of findings between the Rockwood tilt view and the arthroscopic finding. METHODS We developed the arthroscopic classification of acromion spur as type 1 flat ...

PURPOSE To study the innervation of the presumably contractile, myofibroblast-like scleral spur cells in human and cynomolgus monkey eyes. METHODS Serial tangential sections of the scleral spur region of the eyes of 16 human donors and 6 cynomolgus monkeys were investigated with immunocytochemical methods. Antibodies against acetylcholinesterase, synaptophysin, alpha-smooth muscle actin, calc...

Spur cell anemia is a hemolytic anemia seen in severe alcoholic cirrhosis that is characterized by unusual morphology and a decreased ratio of phospholipids to cholesterol in the erythrocyte membrane. We hypothesized that defective phospholipid repair may contribute to the red blood cell (RBC) phospholipid abnormalities of spur cell anemia. Therefore, we compared RBCs from normal control subjec...

A diagnosis of spur cell anemia was made. Spur cell anemia is found in end-stage alcoholic liver disease. The morphologic changes of spur cells are caused by accumulation of excess membrane cholesterol, leading to an impaired deformability and consequently a reduced red cell survival. The prognosis of patients with spur cell anemia is poor, with a median survival of a few months. Liver transpla...

In this study a new approach was proposed to determine optimum parameters of a protective spur dike to mitigate scouring depth amount around existing main spur dikes. The studied parameters were angle of the protective spur dike relative to the flume wall, its length, and its distance from the main spur dikes, flow intensity, and the diameters of the sediment particles that were explored to fin...

This paper describes an upper bound analysis of cold forward extrusion of spur gears with modified tooth profile. Spur gear geometrical parameters such as module, number of teeth, pressure angle, bore radius and addendum modification factor were input to a computer program written in Visual Basic. Then spur gear, billet and extrusion die cavity were modeled automatically in SolidWorks. For uppe...

The scleral spur and scleral roll together form a fibrous hoop which may be detached from adjacent structures as a unit. Tensile tests of the spur-roll resemble reported data on sclera. It is proposed that the circular structure of the spur-roll prevents action of the meridional portion of the ciliary muscle on the trabecular meshwork from collapsing the canal of Schlemm.

The rate and duration of apple fruit growth, cell division, and cell expansion, were considered in relation to within-tree factors affecting them. Fruit size at harvest was found to be related to the position of fruit on the spur, seed number, spur size, number of fruits set on the spur, and the date of flowering. The position of fruit on the spur, and spur size, were related to blossom size, b...
