BACKGROUND: Glutamic acid decarboxylase-65 (GAD65), the enzyme that catalyzes the formation of gamma-aminobutyric acid (GABA), is the major autoantigen in both type 1 (insulin-dependent) diabetes and stiff-man syndrome (SMS). The observation that GAD65 autoantibodies may be present for years before the clinical onset of diabetes raises the question of when GAD65 is available to initiate an immune
GAD65 autoantibodies (GAD65Ab) are important markers for type 1 (insulin-dependent) diabetes mellitus. Although most patients have GAD65Ab at the time of clinical diagnosis, there are also GAD65Ab-positive individuals in the population at low risk of developing type 1 diabetes. The aim of this study was to test the hypothesis that the GAD65Ab reactivity to GAD65 cloned from human, mouse, and rat i
This paper outlines an innovation-focused design research collaboration that connects New Zealand design and manufacturing industry with advanced design thinking about design for desirability, a research area pursued at AFFECT - the Centre for Affective Design Research at Massey University in Wellington (NZ). Nowadays, it’s all about offering products that are desirable; products need to appeal to
Islet cell antibodies (ICA) and glutamic acid decarboxylase antibodies (GAD65Ab) are often present at diagnosis of insulin dependent diabetes mellitus (type I diabetes) and are supposed to decline in level and frequency during the first years of disease. We have analysed ICA and GAD65Ab at onset and after one gear in 395 population based randomly selected 15-34 year old patients newly diagnosed wi
Islet cell antibodies (ICA) are a specific marker for Type 1 (insulin-dependent) diabetes mellitus. ICA are found in the serum of over 80% of newly diagnosed patients and the levels of ICA are directly of prognostic value. Standardisation of ICA and the uniform reporting of ICA levels in international units is critical to preclinical/clinical research and the development of assays for ICA as diagn
OBJECTIVE - To clarify the predictive value of islet cell antibody (ICA) and GAD65 antibody (GADA) present at diagnosis with respect to the need for insulin treatment 6 years after diagnosis in young adults initially considered to have type 2 or unclassifiable diabetes. RESEARCH DESIGN AND METHODS - The patient material was representative of the entire Swedish population, consisting of patients wh
Allogeneic islet transplantation can restore an insulin-independent state in C-peptide-negative type 1 diabetic patients. We recently reported three cases of surviving islet allografts that were implanted in type 1 diabetic patients under maintenance immune suppression for a previous kidney graft. The present study compares islet graft-specific cellular auto- and alloreactivity in peripheral blood
This paper proposes a cohesive and comprehensive framework for perceptual product experience (PPE). The framework aims at bringing together the variety of perceptual experiences that we may have when encountering products and objects. Apart from the core sensorial, cognitive and affective modes, the framework takes into account that any experience has dimensions of presentation and representation,
HLA-associated relative risks of type 1 (insulin-dependent) diabetes mellitus were analysed in population-based Swedish patients and controls aged 0-34 years. The age dependence of HLA-associated relative risks was assessed by likelihood ratio tests of regression parameters in separate logistic regression models for each HLA category. The analyses demonstrated an attenuation with increasing age at
Islet autoantibodies are early markers for Type I (insulin-dependent) diabetes mellitus. The aim of this study was to establish whether islet autoantibodies were present at birth in children who developed Type I diabetes before 15 years of age. Cord blood sera from 81 children who developed Type I diabetes between 10 months and 14.9 years of age were tested for glutamic acid decarboxylase autoanti
Platelet-activating factor (PAF) has been implicated in the development of type 1 diabetes. Our previous studies have suggested that PAF inhibitors reduce insulitis and the frequency of diabetes in BB rats. In this study, serum PAF levels were reduced to address the hypothesis that PAF is important for the development of insulitis. From the age of 35 days on, DP-BB rats were treated with human rec
The genetic etiology of Type 1 (insulin-dependent) diabetes mellitus is complicated by the apparent presence of several diabetes susceptibility genetic regions. Type I diabetes in the inbred BioBreeding (BB) rat closely resembles the human disorder and was previously shown to involve two genes: the lymphopenia (lyp) region on Chromosome (Chr) 4 and RT1(u) in the major histocompatibility complex (M
The fundamental first stage of product interaction is through sensory perception, which generates cognitive and affective experiences. Product perception through sensory feedback is a major component in the end user product appraisal that precedes the elicitation of product emotion. Sensory evaluation is connected to a set of concepts including appraisal, concern and goal oriented objective. The i
Type 1 (insulin-dependent) diabetes mellitus is associated with HLA DR and DQ factors, but the primary risk alleles are difficult to identify because recombination events are rare in the DQ-DR region. The risk of HLA genotypes for type 1 diabetes was therefore studied in more than 420 incident new onset, population-based type 1 diabetes children and 340 age, sex and geographically matched controls
