PURPOSE To determine whether a relationship exists between water diffusion coefficients or diffusion anisotropy and MR-defined regions of normal or abnormal brain parenchyma in patients with cerebral gliomas. METHODS In 40 patients with cerebral gliomas, diffusion was characterized in a single column of interest using a motion-insensitive spin-echo sequence that was applied sequentially at tw...

Microbial degradation of synthetic chelating agents, such as EDTA and nitrilotriacetate (NTA), may help immobilizing radionuclides and heavy metals in the environment. The EDTA- and NTA-degrading bacterium BNC1 uses EDTA monooxygenase to oxidize NTA to iminodiacetate (IDA) and EDTA to ethylenediaminediacetate (EDDA). IDA- and EDDA-degrading enzymes have not been purified and characterized to da...

BACKGROUND Celiac disease (CD) is underdiagnosed, and iron-deficiency anemia (IDA) is a common presentation of CD. No guidelines exist in the literature for screening for CD among those with IDA in the United States. We surveyed hematologists to deter- mine rates of CD screening in patients with IDA. METHODS A survey was e-mailed to members of the American Society of Hematology. RESULTS The...

BACKGROUND AND OBJECTIVE Iron is an essential element that is necessary for all cells in the body. Iron deficiency anemia (IDA) is one of the most common nutritional disorders in both developed and developing countries. The glutathione pathway is paramount to antioxidant defense and glucose-6-phosphate dehydrogenase (G6PD)-deficient cells do not cope well with oxidative damage. The goal of this...

This study compared social looking and response to novelty in preschool-aged children (47-68 mo) with or without iron deficiency anemia (IDA). Iron status of the participants from a low-income community in New Delhi, India, was based on venous hemoglobin, mean corpuscular volume, and red cell distribution width. Children's social looking toward adults, affect, and wary or hesitant behavior in r...

OBJECTIVES To estimate the extent of iron deficiency anaemia (IDA) among children aged 0 - 4 years and pregnant women aged 15 - 49 years, and the burden of disease attributed to IDA in South Africa in 2000. DESIGN The comparative risk assessment (CRA) methodology of the World Health Organization (WHO) was followed using local prevalence and burden estimates. IDA prevalence came from re-analys...

OBJECTIVE Worldwide attention over iron deficiency anemia (IDA) in pregnancy has shifted recently from providing supplements during pregnancy to attempting to ensure that women, especially adolescents, have adequate iron stores prior to conception. We sought to determine whether adolescent and/or adult women still need supplements during pregnancy to avoid IDA, even if iron stores are adequate,...

BACKGROUND Iron deficiency anemia (IDA) is a major health problem during pregnancy and it has adverse effects on the mother and the newborn. Red cell distribution width (RDW), which is a quantitative measure for red cell size variation (anisocytosis), is a predictor of IDA. Little is known regarding RDW and IDA during pregnancy. METHODS A cross sectional study was conducted at the antenatal c...

At the Information-technology Promotion Agency (IPA), we have been developing a network intrusion detection system we have named IDA (for the Intrusion Detection Agent system). IDA has two distinctive features that most conventional intrusion detection systems lack. The rst feature is a mechanism for tracing the origin of the break-in by means of mobile agents. The second feature is the way in ...

This report is a detailed study of physical security methods available for protecting a data center. A preliminary analysis has been done on the data center located at the Department of Computer and Information Science (IDA) of Linköping University, Sweden. Various traditional methods for physical security are discussed in this report along with their implementation. The two appropriate solutio...
