congenital anterior tibiofemoral subluxation is an extremely rare disorder. all reported cases accompanied by other abnormalities and syndromes. a 16-year-old high school girl referred to us with bilateral anterior tibiofemoral subluxation as the knees were extended and reduced at more than 30 degrees flexion. deformities were due to tightness of the iliotibial band and biceps femuris muscles a...

dental implants have provided exceptional rehabilitative options for edentulous and partially edentulous patients. however, as more implants come into play, the more the clinicians come across problems where specific considerations must be taken into account to meet expectations. the toronto bridge is a treatment modality proposed for restoring several teeth lost in patients with increased crow...

A practical Bridge Management System has been developed by the author, which is referred to as the Japanese Bridge Management System (J-BMS) for existing concrete bridges. This paper introduces a newly developed bridge management system for the prestressed concrete (PC) bridges (J-BMS PC version) which is integrated with the PC bridge rating expert system (PC-BREX). The proposed system is able ...

Today’s, the transportation facilities such as terminals, street, bridge, etc, represent the major investment in highway network. Every year tremendous resources should be invested to maintain these facilities. Among them, the Bridge Management System (B.M.S.) has been necessitated by large imbalance between extensive bridge repair and maintenance needs and limited available budget. So the main...

High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

BACKGROUND Myocardial bridges represent a hotly debated research topic. Myocardial bridges are considered to be a vascular heart variation due to its intermittent or enduring reducing of the arterial lumen, with a possible ischemic effect. METHODS 154 hearts were studied, having been extracted as fresh autopsy material. Coronary arteries were injected with synthetic resin and cleaned by extra...

OBJECTIVE It remains debatable whether cervical spine fusion cages should be filled with any kind of bone or bone substitute. Cortical and subcortical bone from the anterior and posterior osteophytes of the segment could be used to fill the cage. The purposes of the present study are to evaluate the clinical outcomes and radiological outcomes including bone fusion and subsidence that occurred a...

The drive for all-ceramic or metal-free dentistry has had its ups and downs over the past decade. However, computer-aided design/computer-aided manufacturing (CAD/ CAM) materials have been introduced into the marketplace for the fabrication of single-unit restorations and 3and 4-unit bridges. These materials hold promise for predictably satisfying the need for esthetic and strong restorations f...

The left coronary artery presents wide variability in its morphological expression. The purpose of this work was to determine the variations in the left coronary artery and those of its branches in heart samples taken from a group of 154 Colombian mixed-race people. Cadaveric coronary arteries were injected with synthetic resins. Left coronary artery trunks presented 6.48 +/- 2.57 mm lengths. L...
