The current work aimed to study the effect of preeclampsia on maternal serum level of beta subunit of human chorionic gonadotropin and maternal plasma level of adenosine deaminase. Ninety pregnant women with gestational age 24 26 weeks were selected for this study, they were classified into three groups: group 1 consists of 30 women with normal pregnancy, group 2 consists of 30 patients with mi...

Alcohol consumption is associated with a number of changes in hepatic cell functions as liver is the major site of its metabolism. Acetaldehyde metabolite formed during metabolism of ethanol is very reactive compound and is indicator of tissue and organ damage. The relationship of serum sialic acid, adenosine deaminase and C-reactive protein in patients of alcohol abuse is unknown so the curren...

The activity of adenosine deaminase was studied in nine cases of rheumatoid pleural effusion, showing an increase in enzyme activity in all. Rheumatoid arthritis seems unique, however, as it cannot be differentiated from pleural tuberculosis on the basis of this test. Selective increase of adenosine deaminase in both conditions is attributed to stimulation of T lymphocytes in the pleural fluid.

Abstract Despite the remarkable outcome of immune checkpoint inhibitors (ICIs) in non-small cell lung cancer (NSCLC), a large number patients remain unresponsive to this therapy. A key factor unresponsiveness ICIs is intrinsic therapeutic resistance where monocytic myeloid-derived suppressor cells (M-MDSCs) contribute significantly via suppressing CD8 +T mediated anti-tumor response. Our result...

Schmidt (1) was the first to extract an enzyme catalyzing the deamination of 5-adenylic acid. He demonstrated the presence of adenosine and adenylic acid deaminases in NaHC03 extracts of saline-washed minced rabbit muscle. Purification of the preparation by adsorption with alumina removed the adenosine deaminase, thus demonstrating that deamination of adenylic acid and adenosine is catalyzed by...

The biochemical mechanisms by which a genetically determined deficiency of adenosine deaminase leads to immunodeficiency are still poorly understood and prompted this study. We have examined the effects of the adenosine deaminase inhibitor erythro-9-(2-hydroxy-3-nonyl) adenine hydrochloride (EHNA) upon the response of human peripheral blood mononuclear cells to the mitogen concanavalin A (Con A...

The metabolic and growth inhibitory effects of adenosine toward the human lymphoblast line WI-L2 were potentiated by the adenosine deaminase inhibitors erythro-9-(2-hydroxy-3-nonyl) adenine (EHNA) and coformycin. EHNA, 5 micron, or coformycin, 3.5 micron, at concentrations that inhibited adenosine deaminase activity more than 90% had little effect on cell growth or the metabolic parameters stud...

Extracellular adenosine is an important signaling molecule in neuromodulation, immunomodulation and hypoxia. Adenosine dysregulation can cause various pathologies, exemplified by a deficiency in adenosine deaminase in severe combined immunodeficiency. We have established a Drosophila model to study the effects of increased adenosine in vivo by mutating the main Drosophila adenosine deaminase-re...
