Objective: This study aimed to systematically review current relevant literature on the prevalence of bimaxillary protrusion. Materials and Methods: The electronic databases PubMed, Medline, Scopus, Google Scholar Cochrane Library were searched using specific inclusion criteria obtain applicable articles. References from included studies also examined. Results: Three articles identified that me...

Many physiological phenomena involve directional cell migration. It is usually attributed to chemical gradients in vivo. Recently, other cues have been shown to guide cells in vitro, including stiffness/adhesion gradients or micropatterned adhesive motifs. However, the cellular mechanism leading to these biased migrations remains unknown, and, often, even the direction of motion is unpredictabl...

Actin-based protrusion is the first step in cell crawling. In the last two decades, the studies of actin networks in the lamellipodium and Listeria's comet tail advanced so far that the last goal of the reductionist agenda - reconstitution of protrusion from purified components in vitro and in silico - became viable. Earlier models dealt with growth of and force generation by a single actin fil...

Purpose: Wearing high-heel shoes has become a habit among women of the present era. Statistics show that around 60% of women wear high-heel shoes at least thrice a week. High-heel shoes cause postural changes and damage body joints. The present study was conducted to assess the effect of high-heel shoes on the head protrusion angle. Methods: This study was conducted at University of Social Wel...

PURPOSE To present the measures for tongue pressure in Brazilian young adults, considering specific tasks, and to verify the differences regarding gender and according to the tasks. METHODS Fifty-one volunteers aged 18 to 28 years, of both genders with normal occlusion and without speech disorders were evaluated. We used the Iowa Oral Performance Instrument in the evaluation of tongue pressur...

The guidance cue UNC-6/Netrin regulates both attractive and repulsive axon guidance. Our previous work showed that in C. elegans, the attractive UNC-6/Netrin receptor UNC-40/DCC stimulates growth cone protrusion, and that the repulsive receptor, an UNC-5:UNC-40 heterodimer, inhibits growth cone protrusion. We have also shown that inhibition of growth cone protrusion downstream of the UNC-5:UNC-...

AimThis systematic review aimed to identify the most effective anchorage methods producing better skeletal, dental, aesthetic and patient experience outcomes in treatment of bimaxillary protrusion.MethodsElectronic databases (Pubmed, Medline, Scopus, Cochrane library) were searched without language restrictions. Unpublished studies for on clinicaltrials.gov. Search terms included proclination, ...

Spontaneous disappearance of a herniated lumbar disc is known to occur. This case study describes a 45-year-old patient whose symptoms of lumbar radiculopathy resolved and follow-up imaging showed complete disappearance of the disc prolapse. This phenomenon strengthens the role of conservative treatment in the management of lumbar disc protrusions.

In this paper an analysis of locally linear embedding (LLE) in the context of clustering is developed. As LLE conserves the local affine coordinates of points shape protrusions as high-curvature regions of the surface are also preserved, while the covariance constraint acts as a force stretching those protrusions and making them wider separated and lower dimensional. A novel scheme for unsuperv...
