INTRODUCTION Bone marrow aspiration (BMA) is a common and useful investigation tool in clinical practice to obtain information about both hematological and non-hematological disorders. The aim of the work was to identify the main indications for BMA in Atbara city, north Sudan and to determine the common diagnoses encountered. METHODS All reports of BMA carried out during a 6-year period from...

We study the out-of-sample forecast performance of two alternative methods for dealing with dimensionality: Bayesian model Averaging (BMA) and principal components regression (PCR). We conduct a different out-of-sample investigation in which the predictors are chosen jointly for both output and inflation using Bayesian variable selection in each out-of-sample recursion using information availab...

BACKGROUND Lymphatic filariasis can be associated with development of serious pathology in the form of lymphedema, hydrocele, and elephantiasis in a subset of infected patients. METHODS AND FINDINGS To elucidate the role of CD4(+) T cell subsets in the development of lymphatic pathology, we examined specific sets of cytokines in individuals with filarial lymphedema in response to parasite ant...

BACKGROUND The purpose is to investigate the clinical significance of body morphomics changes in stage III-IV oropharyngeal cancer patients during concurrent chemoradiotherapy (CRT). METHODS Fifty patients who underwent CRT were selected for body composition analyses by either availability of pre/post treatment DEXA scans or a novel CT-based approach of body morphomics analysis (BMA). BMA cha...

Currently, limited molecular markers exist that can determine where in the spectrum of chronic myeloid leukemia (CML) progression an individual patient falls at diagnosis. Gene expression profiles can predict disease and prognosis, but most widely used microarray analytical methods yield lengthy gene candidate lists that are difficult to apply clinically. Consequently, we applied a probabilisti...

MOTIVATION Selecting a small number of relevant genes for accurate classification of samples is essential for the development of diagnostic tests. We present the Bayesian model averaging (BMA) method for gene selection and classification of microarray data. Typical gene selection and classification procedures ignore model uncertainty and use a single set of relevant genes (model) to predict the...

The organization of axonal projections from the basomedial nucleus of the amygdala (BMA) was examined with the Phaseolus vulgaris leucoagglutinin (PHAL) method in adult male rats. The anterior and posterior parts of the BMA, recognized on cytoarchitectonic grounds, display very different projection patterns. Within the amygdala, the anterior basomedial nucleus (BMAa) heavily innervates the cent...

Bayesian model averaging (BMA) can be seen as the optimal approach to any induction task. It can reduce error by accounting for model uncertainty in a principled way, and its usefulness in several areas has been empirically veri ed. However, few attempts to apply it to rule induction have been made. This paper reports a series of experiments designed to test the utility of BMA in this eld. BMA ...

OBJECTIVE To assess the prevalence of leukemia in a series of bone marrow aspiration (BMA) samples collected to confirm provisional diagnoses of acute idiopathic thrombocytopenic purpura (ITP) in children. DESIGN A retrospective cohort. SETTING All BMA reports at The Hospital for Sick Children, Toronto, Ontario (a tertiary care pediatric hospital), from January 1, 1984, to May 31, 1996, wer...
