tuberculosis pericarditis as a potentially fatal complication of tuberculosis requires effective diagnosis and treatment. we evaluated the efficacy of interferon-gamma (ifn-gamma) and adenosine deaminase (ada) for diagnosing tuberculosis pericarditis in a cohort of iranian patients presenting with pericarditis. we enrolled 38 patients with presentation of pericarditis. all patients underwent di...

The main objective of this work is the study of the phylogeny, evolution and ecological importance of the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, the activity of which represents one of the most important and studied mechanisms used by plant growth-promoting microorganisms. The ACC deaminase gene and its regulatory elements presence in completely sequenced organisms was verifi...

OBJECTIVE Adenosine deaminase acts on adenosine and deoxyadenosine metabolism and modulates the immune response. The adenosine deaminase G22A polymorphism (20q.11.33) influences the level of adenosine deaminase enzyme expression, which seems to play a key role in maintaining pregnancy. The adenosine deaminase 2 phenotype has been associated with a protective effect against recurrent spontaneous...

In fat cells isolated from the parametrial adipose tissue of rats, the addition of purified adenosine deaminase increased lipolysis and cyclic adenosine 3':5'-monophosphate (cyclic AMP) accumulation. Adenosine deaminase markedly potentiated cyclic AMP accumulation due to norepinephrine. The increase in cyclic AMP due to adenosine deaminase was as rapid as that of theophylline with near maximal ...

the effects of allopurinol, acyclovir and theophylline on the activity of adenosine deaminase (ada) were studied in 50 mm sodium phosphate buffer ph 7.5 at 27°c, using a uv– vis spectrophotometer. adenosine deaminase is inhibited by these ligands, via different types of inhibition. allopurinol, as a transition state analog of xanthine oxidase, and acyclovir competitively inhibit the catalytic a...

UNLABELLED Myoadenylate deaminase deficiency is noted in skeletal muscles. It generally presents with exertional myalgias, fatigue and weakness. We present a patient who complained of constant pain unrelated to activity with biopsy finding consistent of myoadenylate deaminase deficiency. KEYWORDS Myoadenylate deaminase deficiency; Myalgia; Pain.

Human adenosine deaminase (EC 3.5.4.4), a key purine salvage enzyme essential for immune competence, has been overproduced in Spodoptera frugiperda cells and in Trichoplusia ni (cabbage looper) larvae infected with recombinant baculovirus. The coding sequence of human adenosine deaminase was recombined into a baculovirus immediately downstream from the strong polyhedrin gene promoter. Approxima...

adenosine deaminase estimation in the diagnosis of tuberculous ascites. Reply SIR,-We acknowledge the pertinent points raised by Lingenfelser and Marks. When our paper was submitted we thought that the role of ascitic adenosine deaminase in the diagnosis of tuberculous peritonitis'2 needed further investigation. Subsequent evaluations of ascitic adenosine deaminase in tuberculous peri-tonitis3'...
