OBJECTIVE Adenosine deaminase (ADA) may be multifunctional, regulating adenosine levels and adenosine receptor (AR) agonism, and potentially modifying AR functionality. Herein we assess effects of ADA (and A1AR) deficiency on AR-mediated responses and ischaemic tolerance. METHODS Normoxic function and responses to 20 or 25 min ischaemia and 45 min reperfusion were studied in isolated hearts f...

BACKGROUND Adenosine deaminase (ADA) is useful in the diagnosis of tuberculous pleural effusion (TPE). This study aims to determine the factors affecting pleural fluid ADA levels and to establish the optimal ADA levels for diagnosis of TPE for different age groups. METHODS This was a retrospective study from January 2007 to October 2011. One hundred and sixty patients who had pleural fluid AD...

BACKGROUND AND PURPOSE Adenophostin A (AdA) is a potent agonist of inositol 1,4,5-trisphosphate receptors (IP(3) R). AdA shares with IP(3) the essential features of all IP(3) R agonists, namely structures equivalent to the 4,5-bisphosphate and 6-hydroxyl of IP(3) , but the basis of its increased affinity is unclear. Hitherto, the 2'-phosphate of AdA has been thought to provide a supra-optimal m...

OBJECTIVE Pleural effusion (PE) adenosine deaminase (ADA) has good performance in detection of tuberculous pleural effusion (TPE). However, few study was conducted for its value in pediatric patients. To evaluate PE ADA in diagnosis of pediatric TPE, a retrospective study was performed. PATIENTS AND METHODS 204 pediatric PE patients were enrolled, and then were grouped into TPE group (77 case...

Adenosine deaminase (ADA) deficiency results in a combined immunodeficiency brought about by the immunotoxic properties of elevated ADA substrates. Additional non-lymphoid abnormalities are associated with ADA deficiency, however, little is known about how these relate to the metabolic consequences of ADA deficiency. ADA-deficient mice develop a combined immunodeficiency as well as severe pulmo...

OBJECTIVES To investigate the possibility of discontinuing adalimumab (ADA) for 1 year without flaring (DAS28-erythrocyte sedimentation rate (ESR) ≥3.2), and to identify factors enabling established patients with rheumatoid arthritis (RA) to remain ADA-free. METHODS Of 197 RA patients treated with ADA+methotrexate (MTX), 75 patients who met the ADA-free criteria (steroid-free and sustained DA...

abstract objective: it has been reported that adenosine deaminase (ada) is a good marker for insulin function but its clinical significance in type 2 diabetes mellitus (t2dm) is not yet characterized. this study aims to assess the association of ada with glycated hemoglobin (hba1c) and uric acid (ua) in t2dm patients. materials and methods: the study population consisted of 120 subjects divided...
