Adults and children seem to essentialize certain social categories. Three studies investigated whether, and how, exposure to ethnic diversity affects this bias. Participants were 516 kindergarten, 2nd grade, and 6th grade Israeli Jewish and Arab children attending regular (mono-cultural) or integrated schools. Study 1 revealed that exposure increased the salience of ethnicity, especially for Je...

QUESTION UNDER STUDY Repetitive skin trauma and reduced pressure pain sensation are necessary components of plantar ulcer risk in patients with diabetic neuropathy. The diagnostic value of measuring pressure nociception to detect ulcer risk is, however, unknown. Instead, measuring the vibration perception threshold (VPT) by 64 Hz graduated Rydel-Seiffer tuning fork has become standard clinical ...

BACKGROUND Several researchers have determined the tumor length to be an important prognostic indictor of esophageal cancer (EC). However, controversy exists concerning the optimal cut-off points for tumor length to predict overall survival. The aim of this study was to determine the prognostic value of tumor length and propose the optimum cut-off point for tumor length in predicting survival d...

We carried out a gene expression profiling study using cDNA array technology with 24 primary glioma tissues of low-grade (oligodendroglioma), intermediate-grade (anaplastic oligodendroglioma and anaplastic astrocytoma), and high-grade (glioblastomas multiforme) tumors and found that insulin-like growth factor binding protein 2 (IGFBP2) was consistently overexpressed only in glioblastoma multifo...

The contamination of ores with wastes or materials of lower than the cut-off grade is referred to as dilution. Dilution is an undesirable phenomenon that, on one hand, reduces the product grade and, consequently, reduces the sales prices and, on the other hand, adds an extra cost to waste production. Therefore, studying and evaluating the dilution risk is important in mining, and especially in ...

BACKGROUND We sought to develop a consensus statement for the use of off-loading in the management of diabetic foot ulcers (DFUs). METHODS A literature search of PubMed for evidence regarding off-loading of DFUs was initially conducted, followed by a meeting of authors on March 15, 2013, in Philadelphia, Pennsylvania, to draft consensus statements and recommendations using the GRADE (Grading ...

background: hepatitis activity index (hai) and fibrosing stage are two important findings during the evaluation of liver samples in patients with chronic hepatitis b. the aim of this study was to determine the hai and fibrosing stage in patients with anti-hbe positive chronic hepatitis b. methods: liver biopsy slides of 72 patients were evaluated at the department of pathology in two teaching h...

background : cd117 is a thyrosin kinase receptor encoded by c-kit proto-oncogene. it is expressed during normal development in some tissues and also in a subset of neoplasia especially gastrointestinal stromal tumors   (gists). treatment with thyrosin kinase inhibitors (e.g., imatinib) is useful in cd117- positive gists. the goal of this study is to investigate the expression of cd117 in glial ...

The purpose of this observational study with a convenience sample is to validate simple measurement the mid-upper arm circumference establish screening points using tape (MUAC) for childhood overweight and obesity between 9 12 years age, or from 4th grade 6th grade. Prior study, pilot validation MUAC measure versus anthropometric standard was carried out. total cut-offs 360 school students. res...

In this paper, wire electrical discharge machining of D3 tool steel is studied. Influence of pulse-on time, pulse-off time, peak current and wire speed are investigated for MRR, dimensional deviation, gap current and machining time, during intricate machining of D3 tool steel. Taguchi method is used for single characteristics optimization and to optimize all four process parameters simultaneous...
