Fourier transform infrared (FTIR) spectroscopy has been established as a fast spectroscopic method for biochemical analysis of cells and tissues. In this research we aimed to investigate FTIR's utility for identifying and characterizing different modes of cell death, using leukemic cell lines as a model system. CCRF-CEM and U937 leukemia cells were treated(More)
The Acute Physiologic Score and Chronic Health Evaluation (APACHE) II and the Simplified Acute Physiologic Scale (SAPS) II are two of the more commonly employed predictors of outcome and performance in the intensive care unit setting. However, controversy persists about whether the scores generated by these systems have similar predictive value. This study(More)
A highly sensitive enzyme-linked immunosorbent assay (ELISA) technique was observed for serological detection of antibodies against platelets. A covalently bound to Sepharose CL-4B was used to enrich sera in the IgG3 subclass of antibodies. The ELISA procedure as applied to detect anti-platelet antibodies in patients with herpes or rubella viral infections(More)
Several disturbances in platelet function have been reported in migraineurs including serotonin (5-HT) metabolism and abnormal aggregability of platelets. The present work compared platelets taken from migraineurs during attacks and at headache-free periods with those of controls. The results demonstrated a tendency to increased aggregability during attacks(More)
BACKGROUND Failure of arterial serum lactate to achieve normal levels has been associated with an increased mortality among medical and trauma patients. At our institution the ability of the patient to normalize arterial serum lactate has been utilized as an end point of resuscitation. In this study, we examine the correlation between length of time to(More)
We assessed clinical results in 145 patients with chronic myeloid leukaemia in chronic phase who satisfied criteria for interferon-alpha failure and were thus eligible for treatment with imatinib at the Hammersmith Hospital. We used univariate and multivariate analyses to develop a risk score based on features defined after treatment for 3 months. We(More)
To test the hypothesis that suboptimal preparation of saphenous veins may adversely affect early patency of aorta-coronary artery bypass grafts, a nonrandomized prospective study was undertaken comparing two methods of saphenous vein preparation prior to grafting. Forty recatheterizations were performed during the postoperative hospital stay (approximately(More)
Echis colorata bites cause impairment of platelet aggregation and hemostatic disorders. The mechanism by which the snake venom inhibits platelet aggregation was studied. Upon fractionation, aggregation impairment activity and L-amino acid oxidase activity were similarly separated from the crude venom, unlike other venom enzymes. Preparations of L-amino acid(More)
The MTT-based assay relies upon the cellular reduction of tetrazolium salts to their intensely colored formazans. The test is easy to perform in hematological malignancies and is adaptable for high throughput of samples, although there are some minor limitations in its application resulting from metabolic interference. This class of assays are highly(More)
