Fixed replacement of maxillary anterior teeth with an associated bony defect has challenged the restoring dentist with problems like weight of the prosthesis thereby leading to weakening of abutment teeth, difficulty in establishing smile line and mechanical stability. This article describes the management of a patient with such defect with a forgotten prosthesis - the Andrew bridge system, whi...

In this paper, a reinforced concrete(RC) bridge built in an interchange, in the city of Kerman (a city located in south of Iran) is examined by the Structural Health Monitoring (SHM) system. During the construction of this bridge such as; the main beams, slab, and retaining walls, some Electrical Strain Gauges were mounted on the main reinforcements at different locations within the body of thi...

In this study, a system for monitoring the structural health of bridge deck and predicting various possible damages to this section was designed based on measuring the temperature and humidity with the use of wireless sensor networks, and then it was implemented and investigated. A scaled model of a conventional medium sized bridge (length of 50 meters, height of 10 meters, and with 2 piers) wa...

introduction traumatic lumbar spondylolisthesis is rare disease and in the literature, different surgical approaches, including anterior, posterior, or combined approaches (posterior and anterior) are used to treat the lesion. case presentation we treated a case of traumatic lumbosacral spondylolisthesis using posterior approach and the patient showed a satisfactory outcome. at the final follow...

Introduction: Although left anterior descending (LAD) artery supplies a large portion of the myocardium, the amount of blood supply provided by LAD is depended on the length of the LAD. The aim of the current study was to evaluate the association between coronary artery dominance and LAD anatomic types in patients with normal epicardial coronary arteries. Methods:...

Any significant loss of meniscal function through injury or menisectomy alters the biomechanical and biological environment of the normal knee, eventually resulting in pain, recurrent swelling, and effusions. Overt secondary osteoarthritis is often the endpoint.1,2 Recognition of these consequences has led to a strong commitment within the orthopedic community to meniscal-sparing interventions....

Muscular bridge (MB) is transient systolic coronary blockage occurring due to exposure of a portion of epicardial coronary arteries to compression during systole as a result of tunneling into the myocardium. Although rare, these patients may develop angina pectoris, severe arrhythmia and myocardial infraction (MI). A 30-year-old male patient presented to the emergency with severe pain with an o...

A new mackielline mite, Mackiella reclinata n. sp., from a South African indigenous palm-tree, Phoenix reclinata, is described in detail using different microscopy techniques. A CSLM study of M. reclinata n. sp. internal genitalia shows that mites of this genus possess teardrop shaped spermathecae, sausage-like spermathecal tubes directed anteriad and a subtrapezoidal anterior genital apodeme w...

FIGURE 1 Snapshot Showing Bridging in the Mid-Left Anterior Descending Artery Before Adenosine Infusion W e report the case of a fit 90-year-old woman presenting with increasing episodes of angina. Diagnostic angiography identified a mid-left anterior descending artery myocardial bridge (MB) (Figure 1, Online Video 1) as well as a moderate diagonal disease. We performed fractional flow reserve ...
