Peripheral vascular disease (PVD) is a common condition often associated with cardiovascular risk factors and events. With the aid of B-mode ultrasound scanning, evidence is emerging that these risk factors and events are significantly related to an increased carotid and femoral intima-media thickness (IMT). More importantly, treatment of these risk factors(More)
The multiple demands placed on small calibre cardiovascular bypass grafts have meant that a synthetic prosthesis with good long-term patency has not been developed. A tissue-engineered graft could fulfil the ideal characteristics present in an artery. However, the great disadvantage of such a conduit is the time necessary for maturation leading to(More)
BACKGROUND Unregulated skin-piercing procedures potentially facilitate the transmission of bloodborne pathogens. In February, 1998, a patient who had recently received autohaemotherapy at an alternative medicine clinic in the UK was diagnosed with acute hepatitis B. The autohaemotherapy procedure involved the drawing of 1 mL of the patient's blood, mixing(More)
It has been a long-term goal to develop non-invasive methods that can detect critical levels of tissue hypoxia to help in the management of chronic lower limb ischaemia. In the present study, skeletal muscle oxygenation was measured using a new Clark-type TCPO2 [transcutaneous PO2 (partial pressure of O2)]/PCO2 (partial pressure of CO2) monitoring system(More)
Endovascular aneurysm repair (EVAR) has quickly gained popularity for infrarenal abdominal aortic aneurysm repair during the last two decades. The improvement of available EVAR devices is critical for the advancement of patient care in vascular surgery. Problems are still associated with the grafts, many of which can necessitate the conversion of the(More)
Depositor is not in dcterms. Note: DRIADE application profile (Carrier et al, 2007) used DDI namespace for Depositor. Can this be done within DC? Type defines the scope of this repository, which is meant to be for research data only, but data for analysis comes in many shapes and sizes. (The DCMI definition of dataset includes database.) We decided to draw(More)
OBJECTIVE To elucidate the clinical relevance of carotid bruits. METHODS A search using PubMed was performed using the terms: 'carotid bruit', 'stroke', 'cerebrovascular symptoms', 'carotid artery stenosis' and 'carotid artery disease' in various combinations. The reference lists of the gathered reports were also considered. RESULTS Current evidence(More)
OBJECTIVE To investigate recent respiratory and influenza-like illnesses (ILIs) in acute myocardial infarction patients compared with patients hospitalised for acute non-vascular surgical conditions during the second wave of the 2009 influenza A H1N1 pandemic. DESIGN Case-control study. SETTING Coronary care unit, acute cardiology and acute surgical(More)
Potential insect vectors for transmission of oak leaf scorch caused by Xylella fastidiosa Wells et al., in pin and red oaks in New Jersey were surveyed by placing yellow sticky card traps in tree canopies and fogging with pyrethrin insecticide during 2002-2006. Thirty-seven Cicadomorpha species were collected from 20 genera in Membracidae, Cicadellidae,(More)
There is a need for biomimetic materials for use in blood-contacting devices. Blood contacting surfaces maintain their patency through physico-chemical properties of a functional endothelium. A poly(carbonate-urea) urethane (PCU) is used as a base material to examine the feasibility of L-Arginine methyl ester (L-AME) functionalized material for use in(More)
