A new lossless test vector compressionn scheme is presentedd whichh combines linear feedback shift register (LFSR) reseedingg andd statistical codingg inn aa powerful way. Test vectors cann be encodedd as LFSR seeds by solvingg aa system of linear equations. The solutionn space of the linear equations cann be quite large. The proposedd methodd takes advantage of this large solutionn space too f...

OBJECTIVE To test the hypothesis that semantic impairment is present in both patients with dementia with Lewy bodies (DLB) and those with dementia of Alzheimer's type (DAT). METHODS A comprehensive battery of neuropsychological tasks designed to assess semantic memory, visuoperceptual function, verbal fluency, and recognition memory was given to groups of patients with DLB (n=10), DAT (n=10) ...

background: visceral leishmaniasis (vl) or kala azar is an infectious disease caused by various species of leishmania parasites. the aim of this study was to detect and compare the presence of anti-leishmania antibodies in the urine of vis-ceral leishmaniasis patients using elisa and dat methods. methods: a total of 30 urine samples were collected from vl patients referred to shiraz (southeast ...

Autoimmune hemolytic anemia (AHA) is a common complication in chronic lymphocytic leukemia (CLL). The UK LRF CLL4 trial is the largest prospective trial in CLL to examine the prognostic impact of both a positive direct antiglobulin test (DAT) and AHA. Seven-hundred seventy-seven patients were randomized to receive chlorambucil or fludarabine, alone or with cyclophosphamide (FC). The incidence p...

A growing number of studies report a deterioration of the executive function (EF) in dementia of the Alzheimer type (DAT). To evaluate EFs in DAT, a new version of the Tower of London (TOL) task, originally developed by Shallice (1982), was adapted. The new version of the test was built up in its easiest possible feature in order to be administrable to earlyor middle-stage demented patients. Se...

Background: The aim of the present study was to examine whether patients with Dementia of Alzheimer’s Type (DAT) show a working memory emotional enhancement effect. Methods: We used an affective version of the working memory operation span test that included negative and positive words as well as neutral ones (as in the classical version). Results: Results showed that while healthy older adults...

This study aimed to evaluate the performance of a fast agglutination screening test (FAST) for serodiagnosis of human Leishmania infantum infection in Iran. FAST is based on the direct agglutination test (DAT) but combines with a higher parasite concentration and is performed with only one serum dilution. The validity of FAST for the detection of L. infantum infection in the field was compared ...

Tau protein concentrations were measured in the CSF of 23 patients with dementia of the Alzheimer type (DAT), 36 patients with multi-infarct dementia (MID), and 23 control subjects. Tau protein concentrations were significantly higher in patients with DAT than in controls (P < 0.001) and patients with MID (P < 0.001). A significantly positive correlation between CSF tau protein and glucose conc...

BACKGROUND The Direct Agglutination Test (DAT) has a high diagnostic accuracy and remains, in some geographical areas, part of the diagnostic algorithm for Visceral Leishmaniasis (VL). However, subjective interpretation of results introduces potential for inter-reader variation. We report an assessment of inter-laboratory agreement and propose a pictorial-based approach to standardize reading o...
