INTRODUCTION The aim of this prospective clinical study was to cephalometrically investigate the dentoalveolar and skeletal changes produced by a removable appliance with palatal crib associated with high-pull chincup therapy in children with Angle Class I anterior open-bite malocclusions. METHODS Thirty children with initial mean age of 8.61 years and mean anterior open bite of 4.01 mm were ...

We use statistical mechanical techniques to model the adaptive immune system, represented by lymphocyte networks in which B cells interact with T cells and antigen. We assume that Band T-clones evolve in different thermal noise environments and on different timescales, and derive stationary distributions and study expansion of B clones for the case where these timescales are adiabatically separ...

BACKGROUND The difficulty in obtaining an acceptable impression increases exponentially as the number of abutments increases. Accuracy of the impression material and the use of a suitable impression technique are of utmost importance in the fabrication of a fixed partial denture. This study compared the accuracy of the matrix impression system with conventional putty reline and multiple mix tec...

Cancer is a leading cause of morbidity and mortality in many countries. Solid tumors generally initiate at one particular site called the primary tumor, but eventually disseminate and form new colonies in other organs. The development of such metastases greatly diminishes the potential for a cure of patients and is thought to represent the final stage of the multi-stage progression of human can...

To slow the inexorable rise of antibiotic resistance we must understand how drugs impact on pathogenesis and influence the selection of resistant clones. Staphylococcus aureus is an important human pathogen with populations of antibiotic-resistant bacteria in hospitals and the community. Host phagocytes play a crucial role in controlling S. aureus infection, which can lead to a population "bott...

In this study, the main features of the Boubaker Polynomials Expansion Scheme (BPES) are outlined on the basis of published, compared and confirmed solution to differently established appliedphysics nonlinear problems. Some new applications of the same scheme in the field of fluids motion and waves dynamics are also discussed. PACS: 2010 02.30.Jr; 02.30.Sa

Human identification is a major task undertaken in forensic sciences. Palato-rugoscopy is based on the principle that no two palates are the same. The study of palatine rugae and the study of fingerprints are sometimes complementary as they operate in similar methods based on same scientific basis. The study intends to describe the shape and gender distribution of the palatine rugae and their p...

Our understanding of inflammation's role in the pathogenesis of myeloproliferative neoplasm (MPN) is evolving. The impact of chronic inflammation, a characteristic feature of MPN, likely goes far beyond its role as a driver of constitutional symptoms. An inflammatory response to the neoplastic clone may be responsible for some pathologic aspects of MPN. Moreover, JAK2V617F mutated hematopoietic...

BACKGROUND Palatal obturators and microvascular free flaps are both used to treat patients with maxillectomy defects, however, the optimal technique remains controversial. METHODS A retrospective analysis of 113 patients undergoing maxillectomy for cancer was performed. Seventy-three patients received an obturator and 40 patients were reconstructed with a free flap. RESULTS Speech intelligi...

The most challenging situations in Forensic Odonto-Stomatology are mass disasters, where the forensic dentist is usually confronted with charred human remains or heavily decomposed or fragmented bodies. This article determines the extent of preservation of palatal rugae for use as an alternative identification tool in such situations, using a study group comprising burn victims and cadavers sim...
