The syncytiotrophoblast microvillous membrane must play a vital role in many essential functions of the placenta. In order to better understand the functional characteristics of this membrane, we have investigated an isolated membrane preparation by a variety of techniques. Electron microscopic observations showed membranous structures similar to microvilli(More)
Background A Guyana-based, internal medicine (IM) post-graduate medical education program was established in 2013. However, lack of formal teaching sessions are barriers to the program's success. Objective To describe the partnership between the University of Calgary and the University of Guyana's internal medicine residency programs (IMRP). This(More)
Tracheal bronchus is a rare anatomic variant in which a bronchus originates from the trachea. Patients may be asymptomatic or present with a variety of respiratory symptoms. We present a case of a patient who presented with a history of poorly controlled asthma and a persistent abnormality of the flow-volume loop. Bronchoscopy revealed a tracheal bronchus(More)
The recent characterization of a vesicular microvillous plasma membrane preparation from human placenta has made possible study of the characteristics of amino acid transport by the isolated membrane. Variation of medium osmolality demonstrated that alpha-aminoisobutyric acid (AIB) is taken up virtually entirely into a vesicular space. Vesicular volume was(More)
Increasing rates of opioid abuse, particularly fentanyl, may lead to more presentations of unusual effects of opioid toxicity. Diffuse alveolar hemorrhage is a rare complication of fentanyl overdose. A 45-year-old male presented in hypoxic respiratory failure secondary to diffuse alveolar hemorrhage requiring intubation. Comprehensive drug screening(More)
A66-year-old man was referred to an urgent eye clinic after one week of experiencing painless proptosis and epiphora (abnormal overflow of tears down the cheek) in his right eye. The intraocular pressure was normal in both eyes. The patient had normal visual acuity but had right-gaze diplopia. No lymphadenopathy was detected on physical examination. The(More)
