OBJECTIVE Long-term pain is a common sequela of thoracotomy, occurring in approximately 50% of patients 2 years after thoracic surgery. Despite this alarming statistic, little is known about the factors responsible for the transition of acute to chronic pain. The aim of the present study is to identify predictors of long-term post-thoracotomy pain. DESIGN(More)
Phages are promising alternatives to antibodies as the biorecognition element in a variety of biosensing applications. In this study, a monolayer of bacteriophage P22 whose tailspike proteins specifically recognize Salmonella serotypes was covalently bound to glass substrates through a bifunctional cross linker 3-aminopropyltrimethoxysilane. The specific(More)
PURPOSE A retrospective review of the fixed mandibular implant (FMI) in oral cancer patients is presented. Success of the device and associated complications are discussed. PATIENTS AND METHODS Eighteen oral cancer patients with an FMI were identified. All were treated at a single institution. Information was obtained from medical records, radiographs,(More)
Collapse?cause' is a colloquial term that is widely used, especially in acute and emergency medical practice in the UK. Patients with 'collapse?cause' can be defined as having suffered 'a physical collapse due to an abrupt loss of postural tone'. There may or may not have been accompanying loss of consciousness. Some patients with 'collapse?cause' will have(More)
Rejoining of DNA double-strand breaks (dsb) was measured in a dsb repair-deficient mutant of CHO cells, xrs-5, after exposure to various doses of X-rays in the range between 15 and 50 Gy. For the experiments plateau-phase cultures were employed and dsb assayed by a pulsed field gel electrophoresis assay, the asymmetric field inversion gel electrophoresis(More)
BACKGROUND Obstacles to the use of patient-controlled analgesia (PCA) by elderly surgical patients have not been well-documented. Age differences in preoperative psychological factors, postoperative pain and analgesic consumption, treatment satisfaction, and concerns regarding PCA were measured to identify factors important to effective PCA use. METHODS(More)
This study tested the hypothesis that high dose systemic alfentanil administered before and during abdominal hysterectomy would pre-empt post-operative pain to a greater extent than administration of either low dose alfentanil or no alfentanil perioperatively. Patients (ASA 1 or 2) were randomly assigned to group 1 (n = 15), no opioid; group 2 (n = 15), low(More)
Protein aggregation underlies an array of human diseases, yet only one small-molecule therapeutic targeting this process has been successfully developed to date. Here, we introduce an in vivo system, based on a β-lactamase tripartite fusion construct, that is capable of identifying aggregation-prone sequences in the periplasm of Escherichia coli and(More)
The paper describes immobilization methods of bacteriophage P22 and tailspike gp9 proteins isolated from P22 on atomic force microscope (AFM) probes. The paper also reports single molecule force spectroscopy (SMFS) using AFM of the immobilized P22 (or gp9) interactions with substrate-supported O-antigenic lipopolysaccharides (LPS) bilayers. LPS covers the(More)
Cardiac troponins have emerged over recent years as the "gold standard" serum biochemical marker for the diagnosis and management for patients with acute myocardial infarction (MI). The relationship between old (creatine kinase; CK) and new (troponin T; TT) markers of myocardial injury were examined in this study of 392 consecutive patients admitted to a(More)
