The shoulder as the most mobile joint in the body has a complex anatomy providing it with an increased range of motion, at the expense of its stability. The complex of ligaments and tendons around the acromioclavicular joint (ACJ) is prone to injury especially during sporting activity or following falls onto the apex of the shoulder. The original classification of ACJ dislocations having been m...

Oral surgeries involving the extraction of cheek teeth have a very high complication rate. Complications have been reported at 32% and as high as 70%. Recognition before occurrence helps the veterinarian to reduce the incidence and be prepared for a complication(s). Common indications for extraction include dental fracture, end-stage periodontal disease, severe decay/cavity, and periapical absc...

Background: The vast percentage of the alveolar bone resorption process happens within first 12 to 24 weeks post extraction; however, this phenomenon is chronic, and ridge continues resorb. In order prevent reduction or at least recompense loss dimensions, preservation (ARP) technique was developed. Objectives: This research studied vertical horizontal dimensional changes as a result non-molar ...

BACKGROUND Adipose tissue development and remodeling are closely associated with the growth of vascular network. We hypothesized that adipose tissue may contain progenitor cells with angiogenic potential and that therapy based on adipose tissue-derived progenitor cells administration may constitute a promising cell therapy in patients with ischemic disease. METHODS AND RESULTS In mice, cultur...

Experimental determination of the elastic modulus and ultimate strength of human tibial trabecular bone as a function of metaphyseal location is presented. A 1 cm cubic matrix with planes parallel to the subchondral plate was defined on five fresh frozen cadaver tibias. Approximately 400, 7 mm X 10 mm cylindrical bone plugs were cut from the locations defined by the matrix and tested in uniaxia...

Temperature is one of the effective parameters in erosion of spark plug electrodes. In this research, temperature of spark plug was measured in engine's different operation conditions with two types of fuels: compressed natural gas and gasoline. Test results showed that, temperature of center electrode is lower than ground electrode and maximum difference between them is 110ºC that occurs at...

Scaffolds prepared from biodegradable polyurethanes (PUR) have been investigated as a supportive matrix and delivery system for skin, cardiovascular, and bone tissue engineering. While previous studies have suggested that PUR scaffolds are biocompatible and moderately osteoconductive, the effects of encapsulated osteoinductive molecules, such as recombinant human bone morphogenetic protein (rhB...
