Glutamic acid decarboxylase (GAD; glutamate decarboxylase, L-glutamate 1-carboxy-lyase, EC, which catalyzes formation of gamma-aminobutyric acid from L-glutamic acid, is detectable in different isoforms with distinct electrophoretic and kinetic characteristics. GAD has also been implicated as an autoantigen in the vastly differing autoimmune(More)
BACKGROUND Bacteria contribute considerably to the progression of lung disease in cystic fibrosis. In this prospective, multi-centre study, we aimed to evaluate the occurrence of emerging bacteria and the physicians' assessments of the clinical importance of these findings. METHODS Twelve CF centres (total number of patients: 1419) reported the detection(More)
The prevalence of cystic fibrosis-related diabetes melltitus (CFRD) is increasing as patients with cystic fibrosis (CF) live longer. Because patients with CFRD are insulin-deficient, the standard medical treatment is exogenous insulin. Sulfonylureas enhance insulin secretion by acting on a specific islet beta cell receptor. No data are available about the(More)
Autoantibodies against the beta-cell M(r) 64,000 protein (p64), recently identified as an isoform of glutamic acid decarboxylase (GAD), are prevalent in patients with insulin-dependent diabetes mellitus (IDDM). Dog islets were found to represent an abundant source of native p64 allowing the study of antigen-antibody interactions in IDDM. A quantitative,(More)
Insulin-dependent diabetes mellitus is associated with a growing number of immune abnormalities. At the time of clinical onset, most patients developing the disease as children or young adults have autoantibodies reactive with islet beta cells. Current autoantibody markers for IDDM are not sufficient to predict the disease in the general population. Studies(More)
First-degree relatives of Type 1 (insulin-dependent) diabetic patients are at increased risk for developing clinical diabetes. The presence of islet cell or insulin autoantibodies further identifies relatives at greater risk, but not all immunologic-marker-positive relatives progress to disease. Beta-cell dysfunction, however, seems to be more prevalent(More)
A retrospective analysis of files of patients with cystic fibrosis and pulmonary exacerbations was performed to investigate whether an individual dosage of tobramycin once established by serum level determination allows a reliable prediction of the adequate dosage in a consecutive exacerbation. All patients hospitalized > or = 2 times between May 1997 and(More)
In rat forebrain tissue of single rats beta-adrenoceptor density (Bmax) and affinity (Kd) were determined by saturation isotherms in receptor binding studies with the antagonist ligand (3H)-dihydroalprenolol at 8 different times of day in May. Rats were on a controlled 12L:12D photoperiod. In addition, the cAMP content, the formation of cAMP from ATP by the(More)
