Interleukin (IL-) 2 acts on a number of types of immune cells promoting their effector functions. To replace systemic administration of recombinant form of this cytokine, various genetically modified cells have been used indifferent preclinical models for tumor growth inhibition. In this study, dendritic or tumor cells transduced with retroviral vector carrying IL-2 gene (JAWS II/IL-2, X63/IL-2...

Background: Combined orthodontic-surgical treatment includes a thorough diagnosis and analysis of dental facial deformities. Cephalometric is common tool for this, in which measurements specific anatomical landmarks are performed. In order to achieve successful surgery, orthodontic teeth preparation mandatory, including decompensation before surgery. This should be planned adequately executed a...

Introduction: Giant cell lesions of the bone comprise a group of jaw bone pathologies. Different pathogeneses such as reactive, vascular or neoplastic have been proposed for these lesions. In addition, differentiating between aggressive and nonaggressive central giant cell granuloma (CGCG) of the jaws based on histopathologic features is still impossible and due to different treatment protocols...

As in gnathostomes, the hagfish feeding apparatus includes skeletal, dental and muscular components. In the present study, we examined feeding morphology and kinematics in two hagfish species, Eptatretus stoutii and Myxine glutinosa, representing the two major hagfish lineages. E. stoutii have larger dental plates, larger basal plates, and stronger clavatus muscles (the major dental plate retra...

The cellulose-rich walls that protect plant cells are difficult to digest, and therefore mechanical food processing is a key aspect of herbivory across vertebrates. Cell walls are typically broken down by translation of flattened teeth in the occlusal plane (i.e. grinding) as part of a complex, rhythmic chewing stroke. The grass carp, Ctenopharyngodon idella, is a voracious, invasive herbivorou...

Intensity-modulated radiation therapy (IMRT) can be delivered inefficiently using the movable jaws of a linac. The efficiency can be much improved by delivering IMRT with the movable jaws together with a relocatable mask below the jaws (Webb 2002 Phys. Med. Biol. 47 257-75). This paper extends the modelling work by showing that a much simpler relocatable mask than previously conceptualized can ...

OBJECTIVES To assess the prevalence, location and anatomical course of accessory canals of the jaws using cone beam CT. METHODS A retrospective analysis of 4200 successive cone beam CT scans, for patients of both genders and ages ranging from 7 to 88 years, was performed. They were exposed at the School of Dentistry, University of Michigan, Ann Arbor, MI. After applying the exclusion criteria...

BACKGROUND Correction of a micro-orbit, caused by clinical anophthalmia is a very challenging task. In hemifacial microsomia a micro-orbit may be combined with hypoplasia of the malar and the ascending mandibular ramus. MATERIAL A 5-year-old patient with hemifacial microsomia is described. Hypoplasia of the malar bone and the tilted occlusal plane were corrected by means of intraoral distract...
