Cloned cDNA sequences of human adenosine deaminase (ADA; adenosine aminohydrolase, EC 3.5.4.4) have been isolated from a cDNA library constructed in bacteriophage lambda gt10. The cDNA for the library was prepared from poly(A)+ RNA isolated from a human T-lymphoblast cell line, CCRF-CEM. The library was initially screened by differential plaque hybridization to labeled cDNA prepared from human ...

OBJECTIVE To evaluate the efficacy and safety of initial combination treatment with adalimumab (ADA) and methotrexate (MTX) versus monotherapy with ADA or MTX during an open-label extension of PREMIER. METHODS Patients with early rheumatoid arthritis (RA) received blinded ADA plus MTX, ADA alone, or MTX alone for 2 years in PREMIER. At Year 2, patients could enroll in an open-label extension ...

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 divi...

A series of adenosine deaminase (ADA) retroviral vectors were designed and constructed with the goal of improved performance over the PA317/LASN vector currently used in clinical trials. First, the bacterial selectable-marker neomycin phosphotransferase (neo) gene was removed to create a "simplified" vector. Second, the Moloney murine leukemia virus long terminal repeat (LTR) promoter used for ...

A marked tissue-specific increase in erythrocyte adenosine deaminase (ADA) activity is associated with an autosomal dominantly inherited hemolytic anemia. We investigated the molecular basis of ADA overproduction by studying reticulocyte ADA mRNA from affected individuals. Analysis of proband reticulocyte ADA cDNA clones revealed normal sequence. RNase mapping demonstrated that the amount of AD...

Adenosine deaminase (ADA) deficiency causes an autosomal recessive form of severe combined immunodeficiency and also less severe phenotypes, depending to a large degree on genotype. In general, ADA activity in cells of carriers is approximately half-normal. Unexpectedly, healthy first-degree relatives of two unrelated ADA-deficient severe combined immunodeficient patients (mother and brother in...

Intention der Fachgruppe: Software garantiert häufig direkt die Sicherheit für Menschen. Ada wird in internationalen Sicherheitsstandards empfohlen und unterstützt in einzigartiger Weise moderne Analyse, Design und Programmiermethoden und damit die Entwicklung großer zuverlässiger Software-Systeme. Die Fachgruppe will über die Konzepte von Ada und deren Bedeutung für die Softwaretechnologie inf...
