BACKGROUND This multicenter phase II trial was conducted to analyze the clinical activity and toxicity of the combination of pegylated liposomal doxorubicin and vinorelbine as first-line treatment in elderly patients with metastatic breast cancer. PATIENTS AND METHODS From August 2002 to August 2004, 42 patients with metastatic breast cancer were(More)
Here we present the synthesis of the new chelating ligands 1-benzothiazol-2-yl-5-(2-hydroxyphenyl)-3-methyl-1H-pyrazole-4-carboxylic acid methyl ester (2a) and 1-(6-chloropyridazin-3-yl)-5-(2-hydroxyphenyl)-3-methyl-1H-pyrazole-4-carboxylic acid methyl ester (2b), obtained in the reaction of 2-methyl-4-oxo-4H-chromene-3-carboxylic acid methyl ester (1) with(More)
INTRODUCTION In the management of dysphagic stroke patients, percutaneous endoscopic gastrostomies (PEGs) are frequently sited early due to the failure of nasogastric tube (NGT) feeding, with NGTs becoming displaced in over 58% of cases. PEG insertion is a procedure with significant mortality and morbidity. We adapted a novel technique of securing NGTs (a(More)

This study investigated the historical trend in resemblance between first-degree relatives for age at death. Data from genealogies of six New England families (N = 13,656) were divided into nine 25 year birth cohorts, 1650-1874, to test the hypothesis that familial influence on human longevity has changed during the past 300 years. Heritability (h2 ) for(More)
A new set of data concerning the pattern of suicide in India between 1991-1997 are presented. Suicide rates rose over this period despite a small decline in the Indian suicide rate in 1995 and 1996. It was found that between 1995 and 1997 there was a modest fall in the suicide rates among under 29-year-olds of both sexes, and an increase among those 30(More)
Indian suicide rates rose by 76% in the 10 years between 1984 and 1994. In this study of the 16 principal states of India, male and female suicide rates in 1994 were associated with measures of equal education for men and women. Male suicide rates were associated with equal life expectancy for men and women. Equal income for women and men was not associated(More)
Our data (Reddy et al., Radiat. Res. 141, 252-258, 1995) on the kinetics of the repair of potentially lethal damage in log-phase Chinese hamster V79 cells are used to test some predictions which arise from the different assumptions of the repair-misrepair (RMR) (C. A. Tobias, Radiat. Res. 104, S77-S95, 1985), lethal-potentially lethal (LPL) (S. B. Curtis,(More)
The aim of this study is to determine whether the repair process in log-phase Chinese hamster V79 cells exposed to X rays is unsaturated, saturable, or saturated. The kinetics of recovery from damage induced by 2 to 14 Gy of 250 kVp X rays was studied by treating cells with 0.5 M hypertonic saline for 20 min at different postirradiation repair intervals.(More)
The purpose of this prospective clinical study was to assess the rate of healing of periapical bony defects created at the time of endodontic periapical surgery by measuring the densitometric ratio change in periapical osseous tissues, after periapical endodontic surgery was performed, by using or not using Guidor bioresorbable membrane material. Periapical(More)
We show by means of experiments, theory, and simulations that the slow dynamics of coarsening systems displays dynamic heterogeneity similar to that observed in glass-forming systems. We measure dynamic heterogeneity via novel multipoint functions which quantify the emergence of dynamic, as opposed to static, correlations of fluctuations. Experiments are(More)
