Serum magnesium was measured in 89 control subjects ages 19 to 86 years and in 64 patients (ages 35 to 82 years) who had suffered from acute myocardial infarction at least 6 months previously. No differences were found in the serum magnesium levels due to age or sex nor was there any statistical difference between the mean levels in the two groups. It is(More)
A given set of data points in some feature space may be associated with a Schrödinger equation whose potential is determined by the data. This is known to lead to good clustering solutions. Here we extend this approach into a full-fledged dynamical scheme using a time-dependent Schrödinger equation. Moreover, we approximate this Hamiltonian formalism by a(More)
We propose a bootstrap method for approximating the long-range terms in the Contractor Renor-malization (CORE) method. The idea is tested on the 2-D Heisenberg antiferromagnet and the frustrated J2 − J1 model. We obtain renormalization group flows that directly reveal the Neel phase of the unfrustrated HAF and the existence of a phase transition in the J2 −(More)
Cytogenetic studies of bone marrow fibroblasts and blood cells from peripheral blood or bone marrow were performed in 19 patients with myelofibrosis with myeloid metaplasia (group 1), nine patients with other myeloproliferative syndromes without myelofibrosis (group 2), and 12 patients with anaemia secondary to iron deficiency or chronic inflammatory(More)
We report the sublocalization of the breakpoint in chromosome 22 in 33 patients with chronic myeloid leukemia (CML) who also had unusual marrow cytogenetics. In 23 patients, the leukemic clones were characterized by Philadelphia (Ph1) chromosomes that arose through complex translocations that involved three or more chromosomes. In the remaining ten(More)
Philadelphia (Ph) chromosome negative chronic myeloid leukemia (CML) can be distinguished from clinically similar disorders on the basis of the presence of rearrangement of the breakpoint cluster region (bcr) of chromosome 22. We have identified six patients with Ph-negative CML, each with bcr rearrangement. Apparently normal karyotypes were observed in two(More)
The relative effect of five commonly used culture media (MEM, BME, McCoy's 5A, M199 and HMEM) on the population doubling level (PDL), nuclear volume and nuclear morphology was examined during in vitro senescence of WI-38 human fetal fibroblasts. Statistical analyses showed that cells grown in M199 had a significantly lower PDL than that of cells cultured in(More)
The azide, dibromide and dichloride radicals oxidize one or more tryptophan side chains in hen egg-white lysozyme. The indolyl radical produced in this second-order 1-electron oxidation subsequently oxidizes a tyrosine side chain to the phenoxy radical in an intramolecular reaction with a rate constant of 130 +/- 10 s-1 at pH 7, 25 degrees C. The final(More)
