This study aimed to clarify the relationships among developmental characteristics of retinoblastoma (RB) infants, mother-infant interaction, and mental health of mothers. Prospective studies were conducted twice with 13 dyads of mothers and infants who were between one (Time 1) and two years old (Time 2). Cross-sectional and longitudinal analyses were performed. The mean Developmental Quotients...
BACKGROUND We previously reported that in patients possessing human leukocyte antigen (HLA)-DQ-directed antibodies, the target molecule may include the patient's own DQβ chain if it is paired with non-self-DQα chain, thus forming a different DQ target. Herein, we sought to assess the breadth of this phenomenon. METHODS Serum samples from 104 patients awaiting kidney transplantation, known to ...
This systematic review examined the current state of conceptualization and specification of data quality and the role of ontology based approaches to develop data quality based on “fitness for purpose” within the health context. A literature review was conducted of all English language studies, from January 2000-March 2013, which addressed data/information quality, fitness for purpose of data, ...
Although donor-specific anti-human leukocyte antigen (HLA) antibodies (DSAs) are frequently found in recipients after lung transplantation (LT), the characteristics of DSA which influence antibody-mediated rejection (AMR) in LT are not fully defined. We retrospectively analyzed 206 consecutive LT patients of our center (2010-2013). DSAs were detected by using luminex single antigen beads assay ...
A query Q is said to be effectively bounded if for all datasets D, there exists a subset DQ of D such that Q(D) = Q(DQ), and the size of DQ and time for fetching DQ are independent of the size of D. The need for studying such queries is evident, since it allows us to compute Q(D) by accessing a bounded dataset DQ, regardless of how big D is. This paper investigates effectively bounded conjuncti...
OBJECTIVE Polyunsaturated fatty acids (PUFAs), including the long-chain (LC) ω-3 PUFAs, are important for health. The aim was to assess if the Anti-Cancer Council of Victoria Dietary Questionnaire (ACC DQ) accurately determines PUFA intakes compared with the recently validated electronic PUFA food-frequency questionnaire (FFQ). METHODS Forty-one study volunteers were recruited from the local ...
This article points out that the differential quadrature (DQ) and differential cubature (DC) methods, due to their global domain property, are more efficient for nonlinear problems than the traditional numerical techniques such as finite element and finite difference methods. By introducing the Hadamard product of matrices, we obtain an explicit matrix formulation for the DQ and DC solutions of...
Using Metadata Analysis and Base Analysis Techniques in Data Qualities Framework for Data Warehouses
Information provided by any applications systems in organization is vital in order to obtain a decision. Due to this factor, the quality of data provided by Data Warehouse (DW) is really important for organization to produce the best solution for their company to move forwards. DW is complex systems that have to deliver highly-aggregated, high quality data from heterogeneous sources to decision...
Studies in myasthenia gravis (MG) patients demonstrate that polymorphism at the HLA-DQ locus influences the development of MG. Several studies using the mouse models also demonstrate the influence of class II molecules, especially the H2-A, which is the mouse homologue of HLA-DQ, in experimental autoimmune myasthenia gravis (EAMG). We used transgenic mice expressing two different DQ molecules, ...
Individuals with ASD often demonstrate elevated rates of challenging behaviors, such as tantrums, aggression, and property destruction. The current study examined the relationship between cognitive abilities and conduct problem behaviors in 263 children aged 18 to 39 months. Cognitive development was measured utilizing the cognitive developmental quotient (DQ) on the Battelle Developmental Inve...
