Expression of green fluorescent protein (GFP) linked to an actin binding domain is a commonly used method for live cell imaging of the actin cytoskeleton. One of these chimeric proteins is GFP-mTalin (GFP fused to the actin binding domain of mouse talin). Although it has been demonstrated that GFP-mTalin colocalizes with the actin cytoskeleton, its effect on actin dynamics and cell expansion ha...

BACKGROUND Patients with bilateral cleft lip-cleft palate have nasal deformities including reduced nasal tip projection, widened ala base, and a deficient or absent columella. The authors compare the nasal morphology of patients treated with presurgical nasoalveolar molding followed by primary lip/nasal reconstruction with age-matched noncleft controls. METHODS A longitudinal, retrospective r...

Pictures show that streamer or sprite discharge channels emerging from the same electrode sometimes seem to reconnect or merge though their heads carry electric charge of the same polarity; one might therefore suspect that reconnections are an artefact of the two-dimensional projection in the pictures. Here we use stereo photography to investigate the full three-dimensional structure of such ev...

for many years, researchers have studied high accuracy methods for recognizing the handwriting and achieved many significant improvements. however, an issue that has rarely been studied is the speed of these methods. considering the computer hardware limitations, it is necessary for these methods to run in high speed. one of the methods to increase the processing speed is to use the computer pa...

different methods arising from scientific investigation for removing noise from chaotic signals have been introduced and one of their best is local projection approach. the local projection approach projects the chaotic data in the neighborhood onto the hyper-plane. selection of neighborhood radius has a direct impact on its performance. a noticeable feature associated with chaotic trajectories...

introduction: monte carlo (mc) is the most common method for simulating virtual spect projections. it is useful for optimizing procedures, evaluating correction algorithms and more recently image reconstruction as a forward projector in iterative algorithms; however, the main drawback of mc is its long run time. we introduced a model based method considering the effect of body attenuation and i...

BACKGROUND Silicone Implants and other alloplastic materials are frequently used in rhinoplasty to augment Asian short noses. However, nasal deformities as a result of implant-related infections are increasing in incidence. The resulting tissue scarrings hinder the application of traditional techniques of lengthening short noses. The following paper presents a technique to correct severe postop...

PURPOSE In this article, a new method of upper lip augmentation using a bilateral buccal fat pad flap is reported. This prospective study evaluated the changes in the upper lip that occur after maxillary surgery with concomitant mobilization of the bilateral buccal fat to improve upper lip projection. MATERIALS AND METHODS A bilateral pedicled buccal fat pad flap to fill the premaxilla, paran...
