Enamel pearls are one of a number of different enamel structures that can be found on the roots of deciduous and pertnanent teeth. They have a distinct predilection for the furcation areas of tnolar teeth, particularly the maxillary third and second molars. They can consist primarily of enamel, but in most instances, a core of dentin is contained within them. On rare occasions, even pulpal tiss...

INTRODUCTION Although researchers develop evidence-based programs for public health practice, rates of adoption and implementation are often low. This qualitative study aimed to better understand implementation of the Program to Encourage Active, Rewarding Lives for Seniors (PEARLS), a depression care management program at a Seattle-King County area agency on aging. METHODS We used stratified...

Presented here is an unusual case of teeth with aberrant enamel. One small and 3 large enamel pearls were identified in 2 maxillary third molars of a patient. One long enamel projection was connected to one of the large enamel pearls, along with 2 short cervical enamel projections. The ectopic enamel was associated with advanced localized periodontal destruction. After extraction, the molars we...

Pearls, the most flawless and highly prized of them, are perhaps the most perfectly spherical macroscopic bodies in the biological world. How are they so round? Why are other pearls solids of revolution (off-round, drop, ringed pearl), and yet others have no symmetry (baroque pearls)? We observe that with a spherical pearl the growth fronts of nacre are spirals and target patterns distributed a...

You are holding a necklace in your hands, composed of no fewer than thirteen exquisite pearls. The pearls are from all over the world, selected for the finest quality, smoothness and lustre. For your viewing pleasure, the necklace emphasizes variety, stringing pearls of wildly different color, shape and size. Satisfaction is guaranteed. This special issue of the Journal of Functional Programmin...

The coiled and dotted vessels in a serpiginous arrangement or "string of pearls" is considered a classical vascular pattern associated with clear cell acanthoma. We present three cases of epidermal tumors different from clear cell acanthoma that have the same "string of pearls" vascular pattern. Even though most authors keep considering the "string of pearls" vascular pattern an almost pathogno...

BACKGROUND Fracture of the ilium is common orthopedic injury that often requires surgical stabilization in canine patients. Of the various methods of surgical stabilization available, application of a lateral bone plate to the ilium is the most common method of fixation. Many plating options are available, each having its own advantages and disadvantages. The purpose of this study was to evalua...

F eral Internal Medicine, Mayo Clinic, Rochester, MN. A t the 2001 Annual Conference of the American College of Physicians, a new teaching format to aid physician learning, Clinical Pearls, was introduced. Clinical Pearls is designed with the 3 qualities of physician-learners in mind. First, we physicians enjoy learning from cases. Second, we like concise, practical points that we can use in ou...

The gathering of pearls from the fresh-water shells of North America, although a matter of comparatively recent date among the present inhabitants, really goes back very far into the unrecorded past, and early attracted notice among the first European explorers. In the prehistoric period the mound-builders of the Mississippi Valley gathered immense quantities of these pearls, as is amply shown ...

The Horizontal Chord Theorem states that if a continuous curve connects points A and B in the plane, then for any integer k there are points C and D on the curve such that −−→ AB = k −−→ CD. In this note, we discuss a few combinatorial-analysis problems related to this theorem and introduce a different formulation that gives way to generalizations on graphs. 1 THE NECKLACE OF PEARLS PROBLEM.
