OBJECTIVES Maximal graft flow acceleration (max df/dt) determined by transit-time flowmetry (TTFM) in the diastolic phase was assessed as a possible predictor of graft failure in coronary artery bypass patients. METHODS Max df/dt was retrospectively measured in 57 in situ left internal thoracic artery grafts. TTFM data were fitted to a 5-polynomial curve, which was derived from the first-deri...

For analysis of the main effects of SNPs, meta-analysis of summary results from individual studies has been shown to provide comparable results as "mega-analysis" that jointly analyzes the pooled participant data from the available studies. This fact revolutionized the genetic analysis of complex traits through large GWAS consortia. Investigations of gene-environment (G×E) interactions are on t...

Ontologies play a key role in realizing the full power of etechnology. Ontologies allow for machine-understandable semantics of data, and facilitate the search, exchange, and integration of knowledge for B2B (business-to-business) and B2C (business-to-consumer) e-commerce. Ontology is defined as “the specification of shared knowledge” (Waterson & Preece, 1999). By using semantic data, the usabi...

INTRODUCTION The administration of crystalloid fluids is considered as the first line treatment in management of trauma patients. Infusion of intravenous fluids leads to various changes in hemodynamic, metabolic and coagulation profiles of these patients. The present study attempted to survey some of these changes in patients with mild severity trauma following normal saline infusion. METHODS...

It is well known that the house dust and the scabies mites are related phylogenetically. We therefore performed atopy patch tests with house dust mite antigens (Dermatophagoides pteronyssinus (Dp) and/or Dermatophagoides farinae (Df)) in scabies patients without atopy and healthy controls. We studied 25 men with active scabies and 25 healthy controls. Skin prick tests with standardized house du...

Introduction: In Ethiopia the prevalence of diarrhea morbidity is more common in rural than in urban areas. To address this problem, interventions have been going on based on the guidelines. There is no study that assessed whether the management of childhood diarrhea is according to the guideline or not. Therefore, the aim of this study was to assess the occurrence of childhood diarrhea and its...

Biochars have increasingly been used as adsorbents for organic and inorganic contaminants in soils. However, during the carbonization process of pyrolysis, contaminants, including polycyclic aromatic hydrocarbons (PAHs) and polychlorinated dioxins and furans (PCDD/DF) can be generated. In this study, biochars made from sawdust, were prepared at various temperatures ranging from 250 to 700 °C. T...

A data flow oriented test selection method for selectively generating abstract tests from a LOTOS specification is presented. This method is based on static data flow analysis to identify maximal IO-df-chains, which exhibit the associations between each specification output and those specification inputs that influence the output through definitions and uses of variables. The maximal IO-df-chai...

Some aspects of Data Fusion (DF) for Information Retrieval (IR) are explored using a set of data from the Fifth International Conference on Text Retrieval, TRECS. It has been observed from time to time that DF applied to a pair of systems or schemes for IR may yield results that are better than those of either participating scheme. It has been conjectured that this occurs only rarely, or occurs...
