OBJECTIVES The effects of operational modes of intra-aortic balloon pumping (IABP) on coronary haemodynamics and oxygen delivery/demand ratio are unknown and were investigated in an experimental model of myocardial ischaemia reperfusion. METHODS Healthy swine (n = 24) underwent 120-minute ligation of the left anterior descending coronary artery followed by 24 h of reperfusion and were randoml...

We describe a randomized incremental algorithm for computing the Delaunay triangulation of a set of points and a recent technique of applying it to terrain generation. The algorithm is optimal, using a Directed Acyclic Graph (DAG)-based location structure for the incremental insertion which achieves an expected running time of O(n log n) and O(n) expected storage. The analysis of the expected s...

INTRODUCTION Data is sparse on drug-induced anaphylaxis (DIA) and there have not been studies assessing the differences in clinical characteristics and management of DIA between adults and children. OBJECTIVE We assessed the percentage, diagnosis, and management of DIA among all anaphylaxis visits in three pediatric and one adult emergency departments (ED) across Canada. METHODS Children pr...

OBJECTIVE Digital image analysis (DIA) offers the opportunity to quantify the stained area and staining intensity when synovial tissue (ST) is investigated by immunohistochemical analysis. This study aimed at determining the sensitivity of DIA compared with semiquantitative analysis (SQA). METHODS Paired ST samples were obtained from the knee joint of 10 patients with rheumatoid arthritis (RA...

The human acute promyelocytic leukemia cell line HL-60 is induced by retinoic acid (RA) and N,N-dimethylformamide (DMF) to differentiate into cells having many of the functional and morphologic characteristics of mature granulocytes. With normal human phagocytic cells there is both superoxide anion (O2-) production and chemotaxis in response to chemoattractants such as N-formyl-methionyl-leucyl...

Adsorption and desorption of atrazine and its metabolites in vegetated filter strip soil (VFS) has not been evaluated, yet these data are needed to predict the transport of these compounds through the VFS. Adsorption and desorption parameters for atrazine, desethylatrazine (DEA), deisopropylatrazine (DIA), and hydroxyatrazine (HA) were compared between a cultivated Houston Black clay (CS) and a...

In this study, we examined whether glycemic status influences aerobic function in women with type 1 diabetes and whether aerobic function is reduced relative to healthy women. To this end, we compared several factors determining aerobic function of 29 young sedentary asymptomatic women (CON) with 9 women of similar age and activity level with type 1 diabetes [DIA, HbA1c range = 6.9-8.2%]. Calf ...

• This paper argues that research on teacher professional development could be integrated with validated theoretical models of educational effectiveness research (EER). A dynamic integrated approach (DIA) to teacher professional development is proposed. The methods and results of a study comparing the impact of the DIA and the Holistic Reflective Approach (HA) to teacher professional developmen...

Diabetes mellitus (DM), the most common metabolic disease, might affect different organs such as male reproductive system. Experiments have shown that n-3 fatty acids could improve male reproductive function. Present study was performed to examine the effects of omega3 on sperms and testicular parameters in diabetic mice. Adult NMRI male mice were randomly divided into intact and diabetic group...

The classic problem of information integration has been addressed for a long time. The Semantic Web project is aiming to define an infrastructure that enables machine understanding. This is a vision that tackles the problem of semantic heterogeneity by using ontologies for information sharing. Agents have an important role in this infrastructure. In this paper we present a new solution, known a...
