D r. Kimberly Lovett was frustrated. Her patient had tested positive on the fecal occult blood test used in colon cancer screening, and as a primary-care doctor in the Department of Family and Preventive Medicine at the University of California, San Diego, Lovett knew the next step in confirming the diagnosis was a colonoscopy. " But why can't you order the blood test? " demanded her patient, d...

Cocaine's ability to block the dopamine transporter (DAT) is crucial for its reinforcing effects. However the brain functional consequences of DAT blockade by cocaine are less clear since they are confounded by its concomitant blockade of norepinephrineand serotonin transporters. To separate the dopaminergic from the non-dopaminergic effects of cocaine on brain function we compared the regional...

An experiment was carried out to assess the effect of four nitrogen levels viz. T1 (full doze of urea i.e. 215 kg urea ha-1 at 15 DAT), T2 (full doze of urea at two equal splits, ½ at 15 DAT + ½ at 30 DAT), T3 (full doze of urea at two equal splits, ½ at 15 DAT + ½ at 55 DAT) and T4 (full doze of urea at three equal splits, 1/3 at 15 DAT + 1/3 at 30 DAT + 1/3 at 55 DAT) on morpho-physiological ...

Neuropsychological profiles were assessed in a large group of nondemented control subjects (n = 261) and individuals with dementia of the Alzheimer type (DAT) (n = 407) by subjecting their psychometric test results to a factor analysis. Nondemented control subjects were functionally homogeneous with only one factor accounting for the results. The results of the factor analysis on the very mild ...

Frequency of irrigation to the crops is the key factor for proper growth and economic yield. Therefore, in the current study growth of broccoli plants was investigated under different irrigation levels in pot culture condition. Five levels of irrigation schedules were applied including I0 [Non-irrigation control], I1 [Irrigation up to 15 days after transplanting (DAT)], I2 [Irrigation up to 30 ...

Direct Antiglobulin Test A DAT may be ordered by a physician who suspects that the patient is experiencing immune-mediated hemolysis (i.e., an antibody is causing the destruction of the patient’s RBCs). If the sample yields a positive DAT with polyspecific antihuman globulin (AHG) reagent, the result may be due to the presence of IgG and/or complement (C3) attached to the patient’s cells. This ...

A simple dot blot test with diacyltrehalose (DAT) as the antigen was developed to detect anti-DAT antibodies in tuberculous patients. To enhance antigen-antibody reaction detection, rabbit serum raised against human immunoglobulins was used prior to incubation with a protein A-colloidal gold complex. With the dot blot system, it was possible to obtain a sensitivity similar to that of enzyme-lin...

Visceral leishmaniasis (VL) is a life-threatening vector-borne parasitic disease is distributed in some parts of the new world and old world. The disease is endemic in different parts of Iran. This review article has been focused on major topics of epidemiological aspects and clinical features of VL in Iran for the period of 2002 through 2012. For the detection of VL in humans as well as animal...

Background: Visceral leishmaniasis (VL) is an endemic disease in some parts of Iran. Many techniques have been used for diagnosis of VL, among which the urine based la-tex agglutination test (KAtex) is a promising one. Objective: To compare three diag-nostic tests of VL including KAtex, ELISA and Direct Agglutination Test (DAT) in VL patients and healthy controls in the south west of Iran. Meth...

in this study which has been carried out from 1996 until 1997 soluble latex agglutination antigen was prepared from L, donovani,sudan(s-1) by culturing in special media,harvesting,and later solubilizing by freezing and thawing.the antigen were futher prepared by high speed centrifugation.after measurement of the protein (lowry method) concentration of the antigen was set at 2.2 mg/ml,the antige...
