The reactive aldehydes methylglyoxal and glyoxal, arise from enzymatic and non-enzymatic degradation of glucose, lipid and protein catabolism, and lipid peroxidation. In Type 1 diabetes mellitus (T1DM) where hyperglycemia, oxidative stress, and lipid peroxidation are common, these aldehydes may be elevated. These aldehydes form advanced glycation end(More)
A more specific antisera against 15alpha-hydroxyestriol (estetrol) was produced in rabbits by immunization with 6-oxoestetrol-6-carboxy-methyloximino-bovine serum albumin. The synthesis of estetrol tetraacetate was greatly improved. Characterization of estetrol antisera revealed that it is more specific than those formerly obtained. A simple method of(More)
Vitamin D deficiency is associated with poor bone health, colorectal cancer, type 1 diabetes and multiple sclerosis. Two national health-related societies in Canada have made recommendations for vitamin D supplementation, yet little research has been reported on the vitamin D status of Canadians. Lifestyle changes, such as sunscreen use, spending less time(More)
BACKGROUND Type 1 diabetes mellitus (T1DM) has been previously been associated with decreased levels of vitamin D. This study investigates the temporal association between average daily ultraviolet B (UVB) irradiance and T1DM in Newfoundland. METHODS A complete list of patients diagnosed with T1DM in the province of Newfoundland and Labrador was(More)
1. The effects of propentofylline (PPF, 25 mg kg(-1) body weight per day) on rat cerebral energy state and cytokine expression as well as on behaviour and histopathology were studied after acute and long-term permanent bilateral common carotid artery occlusion (BCCAO). 2. In the absence of PPF, acute ischaemia led to a decrease in energy-rich phosphates in(More)
OBJECTIVE The aim of this study was to determine the incidence of type 1 diabetes among children aged 0-14 years in the Avalon Peninsula in the Canadian Province of Newfoundland. RESEARCH DESIGN AND METHODS This was a prospective cohort study of the incidence of childhood type 1 diabetes in children aged 0-14 years who were diagnosed with type 1 diabetes(More)
Type 1 diabetes (T1DM) has been previously associated with northern latitude and vitamin D insufficiency. This study investigates the geospatial association between average daily ultraviolet B (UVB) irradiance and T1DM across the province of Newfoundland (NL), Canada. NL has one of the highest documented incidences of T1DM worldwide. A complete list of(More)
OBJECTIVE To determine the incidence of type 1 diabetes mellitus (T1DM) among children aged 0-14 yr inclusive in the Canadian province of Newfoundland and Labrador (NL). METHODS Prospective and retrospective cohort study of the incidence of T1DM in children aged 0-14 yr from 1987 to 2005. Identified cases during this time period were ascertained from(More)
OBJECTIVES Elevated advanced glycation endproducts (AGEs) are implicated in diabetic complications. Methylglyoxal-derived hydroimidazolone (MG-H) is one of the most abundant AGEs in vivo. Our objective was to develop a time-saving, specific method to measure free MG-H in plasma and determine its levels in complication-free young individuals with Type 1(More)
AIM The feasibility of administering native glucagon-like peptide 1 (GLP-1) as GLP-1 Technosphere Inhalation Powder for diabetes therapy has been demonstrated in a rat model. METHODS GLP-1 Technosphere Inhalation Powders containing 5, 10 and 15% GLP-1 were prepared and administered to healthy female Sprague-Dawley rats and to male Zucker diabetic obese(More)
