OBJECTIVE The aim of this study was to evaluate the influence of apical foramen widening on the healing of chronic periapical lesions in dogs' teeth after root canal filling with Sealer 26 or Endomethasone. STUDY DESIGN Forty root canals of dogs' teeth were used. After pulp extirpation, the canals were exposed to the oral cavity for 180 days for induction of periapical lesions, and then instr...

The valence band width of graphite is determined with high accuracy by imaging the momentum distribution of photoelectrons for various binding energies. Compared to local-density-functional theory, the experimental band width ~22.0 eV! is stretched by about 11%. Quasiparticle calculations, which properly describe electron interaction effects on the excited states of a solid, give a width of 21....

The notion that economic integration will bring cultural integration in its train is only partly valid. As I describe in this article, economic development does make societies less nationalistic and more tolerant, trusting, and democratic. But the broad cultural heritage of a society— Protestant, Roman Catholic, Orthodox, Confucian, or Communist—leaves a lasting imprint on values that endures d...

PURPOSE Bronchiectasis and airway wall thickening are commonly assessed in computed tomography (CT) by comparing the airway size with the size of the accompanying artery. Thus, in order to automate the quantification of bronchiectasis and wall thickening following a similar principle, there is a need for methods that automatically segment the airway and vascular trees, measure their size, and p...

BACKGROUND Le Fort I osteotomy imparts significant changes to the nasolabial region. Past studies have relied on 2-dimensional data and have not delineated differences among various Le Fort I subtypes. The purpose of this study is to 3-dimensionally analyze Le Fort I-induced nasal and lip changes comparing advancement alone versus widening alone [surgically assisted maxillary expansion (SAME)] ...

OBJECTIVE The principal mechanism of cardiac toxicity of bupivacaine relates to the blockade of myocardial sodium channels, which leads to an increase in the QRS duration. Recently, experimental studies suggest that lipid emulsion is effective in reversing bupivacaine cardiac toxicity. We aimed to evaluate the temporal evolution of the QRS widening induced by bupivacaine with the administration...

BACKGROUND Pulmonary artery stenting without a long vascular sheath has a special significance, particularly for children with low body weight. Using only a short sheath often permits the implantion of a stent of the correct size; moreover, it improves access to peripherally located stenoses. The aim of this paper is to present the results of a balloon expandable stent implantation into pulmona...

Aims Coronary heart disease is one of the leading causes of mortality in modern societies. The disease is associated with the lack of physical activity and the expression of some genes involved in blood cholesterol transportation. Adenosine triphosphate (ATP)-binding cassette transporters G5/G8) ABCG5 and ABCG8) is the expression of adenosine triphosphate-dependent box protein genes 5 and 8, a ...

Background and Purpose Cerebral magnetic resonance imaging often detects abnormalities whose significance is unknown. The prevalence and correlates of findings such as ventricular enlargement, sulcal widening, and increased white matter signal intensity were examined in 303 men and women aged 65 to 95 years participating in a multicenter study of cardiovascular disease. Methods Cerebral magneti...
