BACKGROUND: Odontogenic myxoma (OM) is a benign intraosseous neoplasm that exhibits local aggressiveness and high recurrence rates. Osteoclastogenesis is an important phenomenon in the tumor growth of maxillary neoplasms. RANK (Receptor Activator of Nuclear Factor κappa B) is the signaling receptor of RANK-L (Receptor activator of nuclear factor kappa-Β ligand) that activates the osteoclasts. OPG (osteoprotegerin) is a decoy receptor for RANK-L that inhibits pro-osteoclastogenesis. The RANK / RANKL / OPG system participates in the regulation of osteolytic activity under normal conditions, and its alteration has been associated with greater bone destruction, and also with tumor growth...

Cryptomelane-type octahedral molecular sieve manganese oxide (OMS-2) possesses high redox potential and has attracted much interest in its application for oxidation arsenite (As(III)) species of arsenic to arsenate (As(V)) to decrease arsenic toxicity and promote total arsenic removal. However, coexisting ions such as As(V) and phosphate are ubiquitous and readily bond to manganese oxide surface, consequently passivating surface active sites of manganese oxide and reducing As(III) oxidation. In this study, we present a novel strategy to significantly promote As(III) oxidation activity of OMS-2 by tuning K+ concentration in the tunnel...

BACKGROUND: Induction of podoplanin by TGF-β has been shown in a number of lesions but not in odontogenic tumors (OTs). We evaluated the association between these markers in OTs for the first time and compared their expression among the different neoplasms. METHODS: Immunohistochemistry using monoclonal antibody against podoplanin and TGF-β was performed on 76 odontogenic cysts and tumors. Spearman's correlation coefficient, Kruskal-Wallis and Mann-Whitney-U tests followed by adjustment with Bonferroni were used for statistical analysis (P<0...

Oral and Maxillofacial Surgery developed initially from Dentistry as exodontia. It then expanded into the surgical management of jaw disorders. As the specialty evolved, it came into increasing conflict with related surgical disciplines. In the 1960s and 1970s these external criticisms were well-founded as training in oral surgery was individual, solely University-based and highly variable. In the 1980s the speciality developed a plan which involved hospital-based surgical training, a mandatory high level college surgical examination and detailed workforce and training studies...

The teaching of OMS to dental students in Australia & New Zealand was surveyed. Generally the established schools had well developed curricula with good didactic and clinical experience conducted by specialist OMS educators. There was a much greater array of teaching in some of the newer schools with some appearing to barely meet the current minimalist professional competencies of the ADC. The critical element was whether or not the school was associated with a speciality OMS Unit at a Teaching Hospital...

Three polyoxometalates (POMs) functionalized by tetrathiafulvalene (TTF) molecules have been synthesized by a coupling reaction between the Anderson-type POMs [MnMo6 O18 {(OCH2 )3 CNH2 }2 ]3- or [AlMo6 O18 (OH)3 {(OCH2 )3 CNH2 }]3- and the TTF carboxylic acid derivative (MeS)3 TTF(S-CH2 -CO2 H). The monofunctionalized TTF-AlMo6 POM contains one TTF group covalently grafted on an Al Anderson platform. The symmetrical TTF-MnMo6 -TTF POM possesses two TTF groups grafted on each side of a Mn Anderson derivative while the asymmetrical TTF-MnMo6 -SP POM contains a TTF and a spiropyran groups...

Giardiasis is one of the most common human intestinal diseases worldwide. Several experimental animals have been used to evaluate Giardia infections, with gerbils ( Meriones unguiculatus ) being the most valuable model due to their high susceptibility to Giardia infection, abundant shedding of cysts, and pathophysiological alterations and signs of disease similar to those observed in humans. Here we report cytokine and antibody profiles both during the course of Giardia infection in gerbils and after immunization with a novel oral vaccine comprising a mixture of purified Variant-specific Surface Proteins (VSPs)...

BACKGROUND: Mental Health problems are widespread globally and are the leading causes of disability. The lives of people living with mental illnesses are often drastically altered by the symptoms of the illness and made worse by the society's reaction. Stigmatizing attitude among general population is prevalent. Relatively less research has been done to explore the attitude of health care providers towards mental illness especially so in Pakistan. This study aims to investigate views of healthcare providers of Abbottabad regarding mental illnesses...

Every year, species of the Mycobacterium tuberculosis complex (MTBC) kill more people than any other infectious disease caused by a single agent. As a consequence of its global distribution and parallel evolution with the human host the bacteria is not genetically homogeneous. The observed genetic heterogeneity has relevance at different phenotypic levels, from gene expression to epidemiological dynamics. However, current systems biology datasets have focused on the laboratory reference strain H37Rv. By using large expression datasets testing the role of almost two hundred transcription factors, we have constructed computational models to grab the expression dynamics of Mycobacterium tuberculosis H37Rv genes...

Oral melanoma (OM) occurs from activated or genetically altered epidermal melanocytes. There is no scientific evidence that OM can be linked to physical, chemical and thermal irritation, or to other risk factors of the oral cavity. According to fi gures from various countries, OM accounts for 0.2% to 7.5% ( Japan) of all cases of melanoma of the skin and mucous membrane. The male to female ratio of OM is 2:1. About 80% of OMs are located in the mucosa of the palate and maxillary gingiva. This paper presents two cases of oral mucosal melanoma of the upper and lower lips in women aged 62 and 59 years...

Studies of cerebrospinal fluid (CSF) γδ T cells in children are limited, especially due to the lack of control data. In adults, gamma/delta T cells (TCR-γδ) residing in the intrathecal space are sometimes involved in neuroinflammation. To evaluate the possible role of γδ T cells in pediatric neuroinflammation, we immunophenotyped CSF and blood lymphocytes using flow cytometry in a case-control study of 100 children with non-inflammatory neurologic disorders (NIND), 312 with opsoclonus-myoclonus (OMS), and 23 with other inflammatory neurologic disorders (OIND)...

Background: Experience suggests that some physicians view obesity as a purely lifestyle condition rather than a chronic metabolic disease. Physicians may not be aware of the role of biological factors in causing weight regain after an initial weight loss. Methods: A questionnaire was administered at continuing medical education conferences, both primary care and obesity-specific. The questionnaire included items about biological and behavioral factors that predispose to weight regain and general items about treatment of obesity...

Objective performance-based outcome measures (OMs) have the potential to provide unbiased and reproducible assessments of limb function. However, very few of these performance-based OMs have been validated for upper limb (UL) prosthesis users. OMs validated in other clinical populations (e.g. neurological or musculoskeletal conditions) could be used to fill gaps in existing performance-based OMs for UL amputees. Additionally, a joint review might reveal consistent gaps across multiple clinical populations. Therefore, the objective of this review was to systematically characterize prominent measures utilized in both sets of clinical populations with regard to (1) location of task performance around the body, (2) possible grips employed, (3) bilateral vs...
