We present a detailed analysis of the possible ways in which the execution of an Ada 95 program might become “totally unpredictable”. In particular, we discuss those language aspects which allow a program execution to become erroneous or which have an undefined semantics. The Ada 95 language definition is assessed with respect to its completeness and clarity in presenting these aspects. The evo...

The Graphical Representations of Algorithms, Structures, and Processes for Ada (GRASP/Ada) project has successfully created and prototyped a new algorithmic level graphical representation for Ada software, the Control Structure Diagram (CSD). The primary impetus to create and refine the CSD is to improve the comprehension efficiency of Ada software, and as a result, improve reliability and redu...

OBJECTIVE To examine the influence of concomitant methotrexate (MTX) with adalimumab (ADA) on outcomes in patients with psoriatic arthritis (PsA) using data from an observational study of ADA. METHODS Data from a German noninterventional study of patients with PsA starting treatment with ADA were analyzed retrospectively for effects of concomitant MTX on key outcomes, including Disease Activi...

We evaluated whether or not the effect of adalimumab (ADA) in combination with the disease-modifying antirheumatic drugs (DMARDs) other than methotrexate (MTX) is comparable to the ADA+MTX therapy for the treatment of rheumatoid arthritis (RA). A total of 216 patients with active RA at Kohnan Kakogawa Hospital and Kobe University Hospital were enrolled. Clinical and functional outcomes wer...

AIM To improve the understanding of factors that influence adenosine deaminase ( ADA) activity in large pericardial effusions. METHODS A prospective study was carried out at Tygerberg Academic Hospital, South Africa. Patients underwent echocardiographically guided pericardiocentesis. ADA activity, as well as biochemistry, haematology, cytology, and in some cases, histology, were determined. H...

Adenosine deaminase (ADA) deficiency is associated with a fatal severe combined immunodeficiency. Because most patients do not have a suitable marrow donor, the introduction of a normal ADA gene into the patient's marrow cells is a potentially useful alternative therapy. To identify vectors that provide optimal gene expression in human hematopoietic cells, we investigated retroviral vectors con...

Adenosine deaminase (ADA) deficiency causes severe combined immune deficiency (SCID) by interfering with the metabolism of deoxyadenosine, which is toxic to T lymphocytes at all stages of differentiation. Enzyme replacement with polyethylene glycol-modified ADA (PEG-ADA) has been previously shown to correct deoxyadenosine metabolism and improve mitogen-induced T lymphocyte proliferation. We stu...

Chagas disease is a public health problem worldwide. The availability of diagnostic tools to predict the development of chronic Chagas cardiomyopathy is crucial to reduce morbidity and mortality. Here we analyze the prognostic value of adenosine deaminase serum activity (ADA) and C-reactive protein serum levels (CRP) in chagasic individuals. One hundred and ten individuals, 28 healthy and 82 ch...

In this work, four water-soluble polythiophene derivatives (PT, PT-DDA, PT-ADA, and PT-ADA-PPR) with different pendant moieties were synthesized via oxidative copolymerization by FeCl3. By increasing the hydrophobic ability of side chain moieties, there is a gradually blue shift for the maximum absorption wavelength and red shift for the maximum emission wavelength, a reducing trend for fluores...

Amniocentesis was performed in two successive pregnancies of the mother of a child with adenosine deaminase (ADA) deficient severe combined immunodeficiency. Assay of ADA in amniotic fluid fibroblasts showed the pregnancies to be normal and homozygous deficient, respectively. These findings were confirmed by the demonstration of a normal level of erythrocyte ADA in the cord blood of the healthy...
