La mordida abierta anterior es una maloclusión caracterizada por la ausencia de contacto los dientes anteriores superiores con inferiores cuando posteriores están en contacto. Esta patología complicada tratar pacientes adultos debido a que produce alteraciones funcionales y estéticas. El tratamiento ortodóntico implica el uso elásticos técnica multi-loop edwegise (MEAW), arcos curva inversa, bl...

Self-ligating brackets include a locking mechanism that holds the archwire in bracket slot. They were created primarily to create lower friction system, allowing for more efficient sliding mechanics and reducing treatment time. Objective: This review aims present all information available on different self-ligating devices, whether active or passive, structured organized way. paper sets out com...

Introduction: The study was conducted to assess the stress and displacement effects of a mini-implant supported k-loop on maxillary dentition for distalization with 3-dimensional (3D) finite element analysis. Materials Methods: A 3D model maxilla all teeth, periodontal ligament, bone, mini-implants, brackets, archwire used in this study. analytic like wire, K-loop, mini-implants developed using...

The purification of coated vesicles and the discovery of clathrin by Barbara Pearse in 1975 was a landmark in cell biology. Over the past 40 years, work from many labs has uncovered the molecular details of clathrin and its associated proteins, including how they assemble into a coated vesicle and how they select cargo. Unexpected connections have been found with signalling, development, neuron...

We reported a new effective approach to carry out two-photon excitation stimulated emission depletion (2PE-STED) microscopy using a single Ti:sapphire laser system. With an acoustic-optic Bragg cell, the modulated-CW 2PE STED microscope had the benefits of both CW and pulse approaches: lower input power, simple optical scheme and no complicated synchronization. Additionally, it also took advant...

The GTPase dynamin has captivated researchers for over two decades, even managing to establish its own research field. Dynamin's allure is partly due to its unusual biochemical properties as well as its essential role in multiple cellular processes, which include the regulation of clathrin-mediated endocytosis and of actin cytoskeleton. On the basis of the classic model, dynamin oligomerization...

Endocytosis occurs in plants, but the involvement of clathrin-coated vesicles has been unclear; a new study provides strong evidence that, as in animal cells, clathrin-coated vesicles are a major means of internalisation by plant cells.

background: ultrasmallsuperparamagnetic iron oxide (uspio) nanoparticles are used as blood pool contrast agent for magnetic resonance angiography and perfusion imaging. our aim in this study was to investigate the effect of the two coating types of iron oxide nanoparticles on the relationship between nanoparticles concentration and signal intensity (si) in t1-weighted mr images.   methods : dif...

Nickel-titanium archwires in orthodontic wires have nickel ion releases. The use toothpaste and saliva immersion time may cause its This study aims to prove the difference interaction between variations towards amount of releases at nickel-titanium archwires. was an experimental research with a post-test only control group design. Twenty seven were divided into three groups, i.e., K group, whic...
