Background The dopamine transporter (DAT) mediates dopamine (DA) reuptake once DA gets released into the synaptic cleft; thereby, the DAT regulates DA content available for synaptic transmission. Psychostimulants like amphetamines can induce the reverse operation and induce outward transport, thereby increasing extracellular dopamine concentrations. Increases of DA in the synaptic cleft are ass...

INTRODUCTION Since there is scarce data available on incidence and type of irregular antibodies in patients and donors in India, a study was undertaken to find the incidence of irregular antibodies in patients and irregular antibodies and a positive Direct Antiglobulin Test (DAT) in blood donors. MATERIALS AND METHODS Antibody screening was performed using commercial pooled "O" cells and thre...

Two cancellation/attentional tasks: (i) Lines Cancellation (LC) and Multiple Features Targets Cancellation (MFTC) and (ii) a standard battery of neuropsychological tests, the Mental Deterioration Battery (MDB), were administered to 68 patients with dementia of the Alzheimer's type (DAT) and 40 patients with multi-infarct dementia (MID), who were accurately matched for the overall severity of de...

The human dopamine transporter (DAT) has a tetrahedral Zn2+-binding site. Zn2+-binding sites are also recognized by other first-row transition metals. Excessive accumulation of manganese or of copper can lead to parkinsonism because of dopamine deficiency. Accordingly, we examined the effect of Mn2+, Co2+, Ni2+, and Cu2+ on transport-associated currents through DAT and DAT-H193K, a mutant with ...

ackground: (2S,3S)-2-(3-Chlorophenyl)-3,5,5,-trimethyl-2-morpholinol hydrochloride (radafaxine) is a new antidepressant that locks dopamine transporters (DAT). A concern with drugs that block (DAT) is their potential reinforcing effects and abuse liability. sing positron emission tomography (PET) we have shown that for DAT-blocking drugs to produce reinforcing effects they must induce 50% DAT b...

BACKGROUND Results of recent radioligand binding experiments suggest that chronic cocaine exposure increases dopamine transporter (DAT) synthesis throughout the striatum of humans. However, detection of cocaine binding site increases in animals and humans has varied depending on the radioligand used. The present experiment tested the hypothesis in cocaine-using humans that synthesis of midbrain...

Canine visceral leishmaniasis (CVL) is endemic in northwestern Iran. This study aimed to compare real-time PCR, conventional PCR, and the direct agglutination test (DAT) for the diagnosis Leishmania infantum infection in 167 serum samples of domestic dog. Bone marrow was used for parasitological examination (smears and/or culture) in symptomatic visceral leishmaniasis, and serum was used for de...

The growth of Cyperus sesquiflorus was characterized in an experiment with 4 replications and 15 treatments (0, 6, 17, 22, 28, 34, 40, 45, 49, 55, 61, 69, 76, 83 90 days after transplanting - DAT). Greater leaf length, diameter the culm, dry matter, biomass partitioning measurements were made. Alive leaves, inflorescences, alive dead tillers counted. Tukey test at 5% used for analysis. length o...

Lanthanum (La) is considered a beneficial element, capable of inducing hormesis. Hormesis is a dose-response relationship phenomenon characterized by low-dose stimulation and high-dose inhibition. Herein we tested the effect of 0 and 10 μM La on growth and biomolecule concentrations of seedlings of four sweet bell pepper (Capsicum annuum L.) varieties, namely Sven, Sympathy, Yolo Wonder, and Zi...

Background: The direct agglutination test (DAT) has proved to be a very important serodiagnostic tool combining high levels of intrinsic validity and ease of performance. Otherwise, fast agglutination screening test (FAST) utilises only one serum dilution making the test very suitable for the screening of large populations. Results: We have tested FAST and DAT for the detection anti-Leishmania ...
