statement of problem: early diagnoses of oral malignancies and pre-malignancies have direct effect in the outcome of these lesions. therefore the techniques for early diagnosis have been considered as useful method in practice. purpose: the aim of this study was to evaluate the reliability of oratest and generic toluidine blue (gtb) in the detection of oral malignancy and premalignancy. materia...

blue nevi are uncommon, asymptomatic lesions of the uterine cervix. these lesions are not often detected clinically or on colposcopy. careful histopathological examination is required. the nevus cells are said to originate from the immature melanoblasts of the neural crest. these lesions need to be differentiated from malignant melanoma and melanosis of the cervix. we present here a case report...

UNLABELLED BACKGROUND This clinical study evaluated the effect of a suctioning maneuver on aspiration past the cuff during mechanical ventilation. METHODS Patients intubated for less than 48 hours with a PVC-cuffed tracheal tube, under mechanical ventilation with a PEEP ≥5 cm H2O and under continuous sedation, were included in the study. At baseline the cuff pressure was set at 30 cm H2O. ...

Multi-level Monte Carlo (MLMC) algorithms have been extensively applied in recent years to obtain schemes that often converge at faster rates than corresponding traditional Monte Carlo methods. In this talk, we shall discuss a randomized method introduced in joint work with Chang-han Rhee, and then describe a stratified alternative estimator. Our principal focus in the talk will be on applicati...

Building on a notion of keys for XML, we propose a novel indexing scheme for hierarchical data that is based not only on the structure but also the content of the data. The index can be used to check the validity of data with respect to a set of key specifications, as well as for efficiently evaluating queries and updates on key paths. We develop algorithms for the construction and incremental ...

C-Phycocyanin is a natural blue dye used in food and pharmaceutical industry. In the present study, a simple and efficient method to extract C-phycocyanin from Spirulina platensis wet biomass is reported. The extractions were carried out using six different methods, including chemical (organic and inorganic acid treatment), physical (freezing and thawing, sonication, homogenization) and enzymat...

Non-song vocalizations of migrating pygmy blue whales (Balaenoptera musculus brevicauda) in Western Australia are described. Simultaneous land-based visual observations and underwater acoustic recordings detected 27 groups in Geographe Bay, WA over 2011 to 2012. Six different vocalizations were recorded that were not repeated in a pattern or in association with song, and thus were identified as...

There is a seasonal cycle of sexual activity for all species of birds. It is more or less pronounced according to the species, and it is primarily controlled by the external factor of light, the daily duration and intensity of which vary during -the year, the minimum amount of light being present on December 21, while the maximum is reached on June 21 in the northern hemisphere. Rowan54 was the...

We propose and demonstrate weak-microcavity organic light-emitting diode (OLED) displays with improved light-extraction and viewing-angle characteristics. A single pair of low- and high-index layers is inserted between indium tin oxide (ITO) and a glass substrate. The electroluminescent (EL) efficiencies of discrete red, green, and blue weak-microcavity OLEDs are enhanced by 56%, 107%, and 26%,...

Lignin peroxidase (LiP), which has been studied extensively in white-rot basidiomycetes and their potential to degrade dyes from textile wastewater, plays a role the biodegradation of lignin pulp paper industry as well agricultural waste. (LsLiP) was successfully purified newly isolated Lentinus squarrosulus MPN12 with 47.1-fold purification 15.7% yield. After 48 h-incubation, LsLiP able decolo...
