BACKGROUND Phosphorylase kinase (PhK), also known as adenosine triphosphate (ATP)-phosphorylase b phosphotransferase, integrates multiple calcium/calmodulin-dependent signalling pathways, including those involved in cell migration and cell proliferation, while coupling these pathways to glycogenolysis and ATP-dependent phosphorylation, thus ensuring(More)
INTRODUCTION Cutiplast (absorbent perforated dressing with adhesive border; Smith & Nephew) is commonly used following orthopaedic operation, but complications of its use have been reported. A prospective, randomised, controlled study was performed to compare the efficacy of Cutiplast versus an Aquacel (hydrofibre dressing; ConvaTec) covered with Tegaderm(More)
BACKGROUND The absence of radiological evidence of plaque on computed tomographic coronary angiography (CTCA) reliably excludes obstructive coronary artery disease. METHODS We studied patients who presented to our emergency department with chest pain and were admitted to our chest pain assessment service. If they were free of pain and without high-risk(More)
Necrotic/gangrenous wounds lack adequate blood supply and develop further vascular damage from either reperfusion injury or oxygen toxicity when exposed to oxygen at the wrong pressures. A prospective randomized study was performed to confirm the efficacy of topical hyperbaric oxygen at 1.004 to 1.013 atmospheres (THOT) in stimulating angiogenesis and(More)
Recent advances in topical hyperbaric oxygen technology identified the use of low-pressure topical hyperbaric oxygen therapy in enhancing wound healing. This study prospectively examined the feasibility of technology transfer from university to Health Maintenance Organization personnel, using topical hyperbaric oxygen therapy to heal necrotic wounds.(More)
BACKGROUND In animals, hydrochloric acid increases blood flow and mucus secretion in the duodenal mucosa. A significant correlation between index of haemoglobin oxygen saturation and mucosal blood flow, and between change in index of haemoglobin concentration and mucus thickness, respectively, has been demonstrated by reflectance spectrophotometry. AIM To(More)
The study explored encoding, storage, and retrieval components of memory functioning in four groups of subjects: (1) normal elderly; (2) elderly subjects in the early prestages of DAT; (3) elderly subjects with a more advanced DAT; (4) younger subjects in the early prestages of AIDS dementia. Each group consisted of 26 subjects, who were administered the(More)
AIMS To explore the impact of the functional severity of coronary artery stenosis on changes in myocardial oxygenation during pharmacological vasodilation, using oxygenation-sensitive cardiovascular magnetic resonance (OS-CMR) imaging and invasive fractional flow reserve (FFR). An FFR is considered a standard of reference for assessing haemodynamic(More)
