A construction is given for a stationary sequence of random variables {X.} which have exponential marginal distributions and are random linear combinations of order one of an i.i.d. exponential sequence {e.}. The Joint and trivariate exponential distributions of X.,, X. and X... are studied, as well as the Intensity function, point spectrum and variance time curve for the point process which ha...

OBJECTIVE To examine the seroprevalence, correlates, and characteristics of undetected coeliac disease in a large adult population sample in Cambridge, UK. METHODS The Cambridge General Practice Health Study invited individuals from 12 general practices, aged 45-76 years, to attend for a health survey that included a bone density measurement, between 1990 and 1995. A total of 7550 participant...

Context: Stroke has several consequences on survivors' daily life even for those who experience short-lasting neurological symptoms with no functional disability. Depression and anxiety are common psychological disorders occurring after a stroke. They affect long-term outcomes and quality of life but they are difficult to diagnose because of the neurobiological consequences of brain lesions. Cu...

  Background and Objectives: Classic Hodgkin lymphoma (CHL), anaplastic large cell lymphoma (ALCL) and some cases of diffuse large B cell lymphoma (DLBCL) have overlapping morphologic features. Since they all represent distinct clinico-pathologic entities, we explored the differential diagnostic impact of immunophenotyping to discriminate between them. Materials and Methods:...

AIM To identify and characterize cancer stem cells (CSC) in moderately differentiated buccal mucosa squamous cell carcinoma (MDBMSCC). METHODS Four micrometer-thick, formalin-fixed, paraffin-embedded MDBMSCC samples from six patients underwent 3,3-diaminobenzidine (DAB) immunohistochemical (IHC) staining for the embryonic stem cell (ESC) markers, NANOG, OCT4, SALL4, SOX2, and pSTAT3; cancer s...

BACKGROUND We prospectively evaluated the usefulness of IgA tissue transglutaminase antibodies (IgA tTG) in the initial diagnosis of celiac disease (CD) and compared its diagnostic potential with that of IgA anti-endomysial antibodies (IgA EMA) and anti-IgA and IgG gliadin antibodies (AGA and AGG, respectively). METHODS Sera of 23 untreated children fulfilling the revised ESPGHAN criteria for...

The association of celiac disease and type I diabetes mellitus has been known for some time. This study was undertaken to investigate the prevalence of celiac disease (CD) in diabetic children and adolescents. Eighty-seven patients (44 females, 43 males) aged 2- 18 years, with type I diabetes participated in this study. A group of 87 healthy unrelated girls and boys matched for age and gend...

The objective of this research is to control the nitrate-nitrogen concentration in surface water to 11.3 mg l (EU standards) and determine the exact nitrogen amount that has to be applied to achieve this limitation and calculate the corresponding plant uptake. The method used in this study is a combination between DRAINMOD-N model and Environmental Management for Agriculture (EMA), applying the...

BACKGROUND Ecological momentary assessment (EMA) may elicit physical activity (PA) estimates that are less prone to bias than traditional self-report measures while providing context. OBJECTIVES The objective of this study was to examine the convergent validity of EMA-assessed PA compared with accelerometry. METHODS The participants self-reported their PA using International Physical Activi...
