the effect of physiological concentrations of caffeine (purified from persian tea) on adenosine deaminase (ada) activity at physiological and pathological concentrations of adenosine (as substrate) in 50 mm tris-hcl buffer (ph 7.3) at 37°c was investigated, using uv-vis spectroscopy. ada exhibited a bi-phasic activity behavior and both phases showed positive cooperativities indicating adenosine...

Background &Objectives: Adenosine deaminase (ADA) is a marker of T cell activation. ADA catalyzes the deamination of adenosine and modulates the bioactivity of insulin. The aim of this study was to investigate a possible relationship between ADA activity and various clinical and metabolic parameters, including fasting plasma sugar (FBS) and glycated hemoglobin (HBA1c), in gestational diabetes (...

    Background & Aim: Adenosine deminase(ADA) can be used in the diagnosis of tuberculous pleural effusions. In countries with high prevalence of tuberculous pleural effusions, specificity and sensitivity for ADA test is high, therefore it is an integral part of a diagnostic workup of lymphocyte-rich exudative body fluids, and it is a cheap and economically cost-effective test. No study has bee...

In human tissues, adenosine deaminase (ADA) (adenosine aminohydrolase; EC 3.5.4.4) activity can be separated by gel electrophoresis into several isozymes. A structural gene (ADA) on chromosome 20 codes for the "erythrocyte" isozyme, ADA-1, which is also expressed in some nonerythroid tissues. Nonerythroid cells also differentially express five ADA "tissue isozymes" of a greater molecular weight...

Hereditary deficiency of adenosine deaminase (ADA) usually causes profound lymphopenia with severe combined immunodeficiency disease. Cells from patients with ADA deficiency contain less than normal, and sometimes undetectable, amounts of ADA catalytic activity and ADA protein. The molecular defects responsible for hereditary ADA deficiency are poorly understood. ADA messenger RNAs and their tr...

  Background and Objective: Brucellosis is a main transmittable zoonotic disease, which is endemic, and a common health burden in Iran. Adenosine deaminase (ADA) is an essential enzyme which is involved in purine metabolism and its role in immune system is very important. The aim of this study was to determine serum changes of ADA and C-reactive protein (CRP) levels in patients with brucellosi...

Polyethylene glycol (PEG)-modified bovine adenosine deaminase (ADA) is used for replacement therapy of severe combined immunodeficiency disease due to inherited ADA deficiency. We monitored IgG anti-ADA antibody in 17 patients treated by intramuscular injections of PEG-ADA for 1 to greater than 5.5 yr. ELISA-detectable anti-ADA IgG appeared in 10 patients, usually between the third and eighth m...

Background and Aims: The aim of the present study was to re-evaluate the upper limit of normal range (ULN) for adenosine deaminase (ADA) level in cerebrospinal fluid (CSF) of healthy subjects in Indian population. Materials and Methods: Posteriori strategy was used for reference population selection. Individuals whose CSF samples had come to the laboratory of Bhatia Hospital, Mumbai (India) ...

BACKGROUND AND PURPOSE We sought to characterize the evolution of apparent diffusion coefficient (ADC) and apparent diffusion anisotropy (ADA) in acute stroke and to evaluate their roles in predicting stroke evolution and outcome. METHODS We studied 26 stroke patients acutely (<24 hours), subacutely (3 to 5 days), and at outcome (3 months). Ratios of the ADC and ADA within a region of infarct...
