To evaluate the association of autoimmunity to glutamic acid decarboxylase (GAD) with insulin-dependent diabetes mellitus (IDDM) and IDDM-associated human leukocyte antigen (HLA) types, we studied a unique group of 47 patients with autoimmune polyendocrine syndrome type 1, a recessive disease not associated with HLA. GAD65 antibodies (GAD65-Ab), GAD67-Ab, islet cell antibodies, and HLA-DQA1, -DQB1
The aim of this study was to determine the association between childhood insulin-dependent diabetes mellitus (IDDM) and HLA-DR4 subtypes and to test in a population-based investigation whether the DR4 association has an effect independent to that of DQ. First, HLA genotyping identified DR4 in 337/425 (79%) patients and 148/367 (40%) controls (Odds Ratio 5.67; p < 0.01). Second, a total of 14 DR4 s
The association between HLA-DQ haplotypes and insulin-dependent diabetes mellitus (IDDM) was studied in 48 children from 44 families ascertained from the high incidence area around Umea, Sweden. Numerous hypotheses have been proposed to explain associations between HLA and IDDM, but comparisons of statistical models based on these hypotheses have not been attempted. The aim of the present study wa
To analyze whether HLA may be a determinant of the risk of developing cervical cancer precursor lesions, the association between HLA and cervical neoplasia among HPV16-seropositive and -negative subjects was determined in a population-based cohort in the Vasterbotten county of Northern Sweden. HLA genotyping of DR and DQ was done by PCR in 74 patients and 164 healthy controls matched for age, sex
The prevalence and titre of epitope-specific autoantibodies to glutamic acid decarboxylase (GAD65) in 155 insulin-dependent diabetic (IDDM) and 9 GAD65 antibody (Ab)-positive healthy children were determined using four GAD65/67 chimaeric molecules which discriminate among the N-terminal (N), middle (M) and C-terminal (C) epitopes of GAD65. Radioligand binding assays for IgG Ab used immunoprecipita
Glutamic acid decarboxylase (GAD) enzymes catalyse the formation of gamma-aminobuturic acid (GABA), which is a major transmittor in the central nervous system but also exerts functions in peripheral organs. Recent molecular analyses have revealed surprising new roles for the GAD isoforms in human diseases of autoimmune character including neurological disorders and insulin-dependent diabetes. In t
It was recently reported that antibodies against glutamic acid decarboxylase (GADAb) have a high positive predictive value for insulin-dependency in non-insulin-dependent diabetic (NIDDM) patients. We studied 289 patients classified at onset as having NIDDM. Patients positive for GAD65Ab had a disease onset at a younger age, lower body mass index (BMI) and lower serum C-peptide concentration, and
Many flying animals, like birds feeding their young, make commuting flights between a central place and foraging areas in the surroundings. Such central place foraging (CPF) represents a special case of foraging theory. We use simple geometry and trigonometry to analyse CPF flight performance (a round-trip cycle of outward flight from the central place and inward flight back along the reverse trac
Aim: The aim of this study was to evaluate the therapeutic efficacy and safety profile of orally administered low-dose ketamine for procedural pain management in pediatric cancer patients undergoing lumbar puncture (LP) in a resource-limited hospital setting. Methods: Patients between 4 and 15 years of age, with leukemia, undergoing LP were asked to participate. The study was designed as a t
The development of formulation concepts for improved skin tissue oxygenation, including methods for measuring oxygen (O2) transport across biological barriers, are important research topics with respect to all processes that are affected by the O2 concentration, such as radiation therapy in oncology treatments, wound healing, and the general health status of skin. In this work we approach this top
AIM: To study to what extent tumor-specific treatment (chemo- or radiotherapy) was given during the last 30 days in life and to examine how many of the patients were referred to a specialized palliative care unit (PCU), at a low-resource governmental hospital in India.PATIENTS AND METHODS: Medical records of adult cancer patients deceased between April 1 and May 31 in 2016, and pediatric cancer pa
Study aims: To prospectively assess the diagnostic accuracy of a pelvic sentinel lymph node (SLN) algorithm in high-risk endometrial cancer (HREC). Patients and methods: Consecutive women with presumed FIGO stage I-II HREC underwent robotic surgery at two academic centres by five accredited surgeons. An anatomically based algorithm was adhered to, following cervical injection of indocyanine green
BACKGROUND: The progression of tumor growth requires the recruitment of new blood vessels. It has been suggested that the degree of neovascularization would correlate with clinical prognosis. The purpose of the present study was to ascertain whether tumor vascularization correlated with clinical outcome in cases of primary squamous cell carcinoma of the head and neck (SCCHN).METHODS: In tumor biop
