OBJECTIVE The purpose of this study was to measure the toe-brachial index (TBI) in healthy young adults and to compare it with the accepted reference range. METHODS Medical students from the undergraduate classes at the University of British Columbia were prospectively recruited. Participants were surveyed on physical parameters (height, weight),(More)
The low-density lipoprotein receptor (Ldlr) is a key molecule involved with lipid clearance. The Ldlr(-/-) mouse has been used extensively as a model for studying atherosclerosis. This study sought to characterize the energy balance phenotype of Ldlr(-/-) mice with respect to weight gain, body composition, energy expenditure (EE), glucose homeostasis, and(More)
Islet transplantation is an effective method to obtain long-term glycemic control for patients with type 1 diabetes, yet its widespread use is limited by an inadequate supply of donor islets. The hormone leptin has profound glucose-lowering and insulin-sensitizing action in type 1 diabetic rodent models. We hypothesized that leptin administration could(More)
AIMS/HYPOTHESIS Leptin has profound glucose-lowering effects in rodent models of type 1 diabetes, and is currently being tested clinically to treat this disease. In addition to reversing hyperglycaemia, leptin therapy corrects multiple lipid, energy and neuroendocrine imbalances in rodent models of type 1 diabetes, yet the precise mechanism has not been(More)
BACKGROUND Terminal myelocystocele is a severe form of spinal dysraphism characterized by cystic expansion of the terminal spinal cord that herniates through a deficiency of the posterior sacral spinal elements to fuse with the subcutaneous fat. Postnatal enlargement of the subcutaneous fluid-filled sac may result in progressive neurological deficit and(More)
Hunter syndrome is a multisystem genetic disease in which a significant proportion of morbidity and mortality arise from respiratory dysfunction. Notably, tracheal abnormalities in Hunter syndrome can compromise clinical stability, and management is primarily supportive. We describe here the first successful implementation of aorto-tracheopexy in a(More)
OBJECTIVE Leptin reverses hyperglycemia in rodent models of type 1 diabetes (T1D). Direct application of leptin to the brain can lower blood glucose in diabetic rodents, and can activate autonomic efferents and non-shivering thermogenesis in brown adipose tissue (BAT). We investigated whether leptin reverses hyperglycemia through a mechanism that requires(More)
PURPOSE To demonstrate the utility of swept-source anterior segment optical coherence tomography (SS-AS-OCT) in guiding placement of transconjunctival sutures in hypotonous patients after a trabeculectomy. PATIENTS AND METHODS This is a longitudinal case series of 10 eyes from 10 patients who required transconjunctival sutures after a trabeculectomy.(More)
The "stinger" or "burner" is a form of transient brachial plexopathy termed for its characteristic knife-like pain extending from the neck to the fingertips. Muscle weakness and paresthesia are oftentimes associated symptoms and are similarly temporary. Commonly observed in athletes of contact sports, the stinger results from high force trauma causing(More)
Leptin signaling in the central nervous system, and particularly the arcuate hypothalamic nucleus, is important for regulating energy and glucose homeostasis. However, the roles of extra-arcuate leptin responsive neurons are less defined. In the current study, we generated mice with widespread inactivation of the long leptin receptor isoform in the central(More)
