Inflammation in multiple sclerosis and its animal model, experimental autoimmune encephalomyelitis (EAE), is manifested by changes in matrix metalloproteinase (MMP) expression and in the ratio of T helper (Th) 1 and 2 effector cytokines. Here, we provide a comprehensive documentation of MMPs in EAE and report that of all the MMPs that could be measured at(More)
BACKGROUND Novel mobile phone technology linked to a server that communicates patients' symptoms to healthcare professionals has been adapted to register the side- effects of chemotherapy and provide advice on management of toxicity. We report a feasibility study to examine the utility of home monitoring of patients' symptoms via a mobile phone. METHODS(More)
One of the targets of free radicals and neutrophil-derived oxidants that is known to be generated during ischemic-reperfusion injury of the myocardium is the sarcolemma. We therefore examined the susceptibility of sarcolemmal Na(+)-K(+)-ATPase and ouabain binding sites to O2-., H2O2,.OH, HOCl, NH2Cl, and stimulated neutrophils. O2-. generated from xanthine(More)
Carcinoid tumors are a fascinating group of neuroendocrine neoplasms that develop either sporadically or as part of an inheritable syndrome. Many tumors arise in the bronchopulmonary or gastrointestinal tract, but a neuroendocrine tumor can arise in almost any organ. The tumors have varied malignant potential depending on the site of their origin, and the(More)
An important aspect of myocardial injury is the role of neutrophils in post-ischemic damage to the heart. Stimulated neutrophils initiate a series of reactions that produce toxic oxidizing agents. Superoxide rapidly dismutases to H2O2 and neutrophils contain myeloperoxidase which catalyzes the oxidation of Cl- by H2O2 to yield hypochlorous acid (HOCl). The(More)
Colorectal cancer is a major health problem in developed countries, accounting for a significant proportion of deaths in the population. Advances in chemotherapy treatment have led to therapy being delivered in the home-setting, which presents challenges in ensuring that treatment-related side-effects are detected and reported to clinical staff in an(More)
Although DNA repair proteins in bacteria are critical for pathogens' genome stability and for subverting the host defense, the role of host DNA repair proteins in response to bacterial infection is poorly defined. Here, we demonstrate, for the first time, that infection with the Gram-negative bacterium Pseudomonas aeruginosa significantly altered the(More)
Real-time symptom monitoring using a mobile phone is potentially advantageous for patients receiving oral chemotherapy. We therefore conducted a pilot study of patient dose adaptation using mobile phone monitoring of specific symptoms to investigate relative dose intensity of capecitabine, level of toxicity and perceived supportive care. Patients with(More)
BACKGROUND Antiangiogenic agents have established efficacy in the treatment of metastatic colorectal cancer. We investigated whether bevacizumab could improve disease-free survival in the adjuvant setting after resection of the primary tumour. METHODS For the open-label, randomised, controlled QUASAR 2 trial, which was done at 170 hospitals in seven(More)
UNLABELLED Diabetic foot ulcers (DFUs) occur as a result of multifactorial complications and are commonly found in the diabetic community. Underlying disease states such as neuropathy and peripheral vascular disease can slow healing rates, potentially leading to recurrence, amputation, and increased mortality. As with many other disease processes, DFUs have(More)
