Surgical approaches to the condylar fracture include intraoral, preauricular, submandibular, and retromandibular approaches. Each approach has its own advantages and disadvantages. When a patient needs esthetic results and an intraoral approach is not feasible, the transmasseteric antero-parotid facelift approach is considered. This approach permits direct exposure and allow the surgeon to fixa...

Dentists may be asked to provide consultations for patients who have sustained trauma to their facial structures. Supraorbital rim fractures, although uncommon, must be recognized and promptly referred to an oral and maxillofacial surgeon or other specialist skilled in the management of facial bone fractures. Supraorbital rim fractures commonly coexist with other craniomaxillofacial injuries, e...

Exploiting the working face in coal mines using a super long mining length and large height has become important for intensive production with high yield efficiency. The paper develops roof structure model to analyze influence of 195 m, 242.4 376 m lengths at Wangzhuang Coal Mine China as case study. fracture characteristics, migration law, strata behavior law under different are compared studi...

The effects of chilling in the light (4 days at 5 degrees C and 100-200 micromoles of photons per square meter per second) on the distribution of chlorophyll (Chl) protein complexes between appressed and nonappressed thylakoid regions of pumpkin (Cucurbita pepo L.) chloroplasts were studied and compared with the changes occurring during in vitro heat treatment (5 minutes at 40 degrees C) of iso...

The intercellular junctions in the anterior myoepithelium and posterior pigmented epithelium of the rhesus monkey iris were examined using an ultrastructural tracer, conventional electron microscopy, and the freeze-fracture technique. Within the anterior myoepithelium the lateral cell margins were joined by puncta adhaerentia, desmosomes, and gap junctions. The distribution of the puncta adhaer...

In vitro aged sheep erythrocytes and sheep erythrocyte ghosts spontaneously release vesicles that consist of long protrusions affixed to flattened headlike structures. The intramembranous particles seen on the protoplasmic face of freeze fracture electron micrographs of vesicle protrusions are arranged in paired particle rows. On the equivalent fracture face of headlike structures, the particle...

OBJECTIVE The aim of this study was to analyse the various factors affecting functional recovery of earthquake survivors with tibial shaft fractures in Sichuan, China, and to provide a clinical reference for the future management of people injured in earthquakes. METHODS A total of 174 earthquake survivors with tibial shaft fractures were investigated using a face-to-face survey 15 months aft...

OBJECTIVE To examine the effect of trauma velocity on the pattern of Le Fort I facial fractures. METHOD A retrospective medical record review was conducted on a consecutive cohort of craniofacial traumas surgically treated by a single surgeon between 2007 and 2011 (n=150). Of these cases, 39 Le Fort fractures were identified. Patient demographic information, method of trauma and velocity of i...

In freeze-fracture (FF) preparations of ADH-stimulated toad urinary bladder, characteristic intramembrane particle (IMP) aggregates are seen on the protoplasmic (P) face of the luminal membrane of granular cells while complementary parallel grooves are found on the exoplasmic (E) face . These IMP aggregates specifically correlate with ADH-induced changes in water permeability . Tubular cytoplas...
