STUDY DESIGN A radiological study of type II Modic changes (MCs). OBJECTIVES The aim of this study was to determine the characteristics of type II MCs on fat suppression (FS) magnetic resonance (MR) images and its association with radiological disc degeneration. SUMMARY OF BACKGROUND DATA Type II MCs are common endplate signal changes on MR images. On the basis of limited histological sampl...

PARACENTESIS TYMPANI or, better, myringotomy, means the incision of the tympanic membrane. It was first advocated and used by a Parisian charlatan named Eli, who flourished in the latter part of the eighteenth century. It had its first legitimate employment at the hands of Himley and Cooper during the beginning of the nineteenth century. The indications for the operation at this time were legio...

STUDY DESIGN Prospective MR analysis of the cervical spine of 30 asymptomatic volunteers. OBJECTIVES To evaluate the prevalence of annular tears, bulging discs, disc herniations and medullary compression on T2-weighted and gadolinium-enhanced T1-weighted magnetic resonance (MR) images of the cervical spine in symptom free volunteers. SUMMARY OF BACKGROUND DATA Few studies have reported the ...

Despite recent advances in prosthetics and assistive robotics in general, robust simultaneous and proportional control of dexterous prosthetic devices remains an unsolved problem, mainly because of inadequate sensorization. In this paper, we study the application of regression to muscle activity, detected using a flexible tactile sensor recording muscle bulging in the forearm (tactile myography...

When a swelling soft solid is rigidly constrained on all sides except for a circular opening, it will bulge out to expand as observed during decompressive craniectomy, a surgical procedure used to reduce stresses in swollen brains. While the elastic energy of the solid decreases throughout this process, large stresses develop close to the opening. At the point of contact, the stresses exhibit a...

BACKGROUND AND AIMS Coordination of sugar transport and metabolism between developing seeds and their enclosing fruit tissues is little understood. In this study the physiological mechanism is examined using two genotypes of asparagus bean (Vigna unguiculata ssp. sesquipedialis) differing in pod wall and seed growth rates. Pod growth dominates over seed growth in genotype 'Zhijiang 121' but not...
