The loss of anterior tooth can be hurtful to the patient both psychologically and socially. In adolescent patients, temporary replacement of teeth can minimize these concerns. Many approaches have been described for this temporary replacement. Adhesively luted, fiber-reinforced retained fixed partial denture (FPD) can be a clinical alternative for the replacement of missing anterior tooth in se...

A new fMRI complex working memory span paradigm was used to identify brain regions making domain-general contributions to working memory task performance. For both verbal and spatial versions of the task, complex working memory span performance increased the activity in lateral prefrontal, anterior cingulate, and parietal cortices during the Encoding, Maintenance, and Coordination phase of task...

We introduce a new class of edge labelings for locally finite lattices which we call SB-labelings. We prove for finite lattices which admit an SB-labeling that each open interval has the homotopy type of a ball or of a sphere of some dimension. Natural examples include the weak order, the Tamari lattice, and the finite distributive lattices.

Most of the human hearts presents a specialized bridge known as Septomarginal trabecula which extends from the right side of the ventricular septum to the base of anterior papillary muscle. For the present study we took 30 human hearts. We studied the thickness of the septomarginal trabecula, the height of its attachment to the ventricular wall by considering the supraventricular crest as the l...

Avulsion and luxation account for up to 16% of all traumatic injuries in the permanent dentition and 7.2% of injuries in the primary dentition. A range of treatment options are available that can help conserve the tooth after a traumatic episode. There are, however, occasions where loss of the traumatized tooth is inevitable with special regard to avulsion injuries. replantation of teeth having...

Tibial eminence avulsion fractures are rare injuries occurring mainly in adolescents and young adults. When necessary, regardless of patient age, anatomic reduction and stable internal fixation are mandatory for fracture healing and accurate restoration of normal knee biomechanics. Various arthroscopically assisted fixation methods with sutures, anchors, wires, or screws have been described but...

acoma aneurysms are complicated and high incidence lesions. the successful treatment depends on understanding the anatomical location of aneurysm. the early surgery and selecting the superior method of surgery and post-operative cares affect the surgical outcomes of these patients. in this study 30 patients who were admitted to firoozgar hospital in a 3-year period (2001-2004), undergone surger...

Performance of structures during recent earthquakes shows that the effect of vertical component of earthquake (VCE) could be considered as one of the main causes of bridges collapse. In most of bridge design codes, for seismic analysis of bridges, VCE is not taken into account or a distinguished method isn’t presented for assessment of VCE. In the present work, the effect of VCE on two existing...
