Neocarzinostatin (NCS) is an antitumor antibiotic comprising a 1:1 protein-chromophore complex and exhibits cytotoxic action through DNA cleavage via H-abstraction. Cytotoxic activity resides with the chromophore 1 alone, while the protein (apoNCS) protects and transports labile 1. The naphthoate portion (2) of NCS chromophore (1) is important for binding to apoNCS and DNA intercalation. In thi...
Although the majority of patients with chronic lymphocytic leukaemia (CLL) are of advanced age, these patients have not been well represented in past clinical trials. This has resulted in a lack of evidence that has complicated treatment in this patient group. However, data from an increasing number of subgroup analyses of recent trials as well as from trials specifically designed for elderly p...
Mucosa-associated lymphoid tissue-derived (MALT) lymphoma, a low grade B-cell extranodal lymphoma, is the most frequent subset of primary pulmonary lymphoma. Our objective was to evaluate the initial extent of disease and to analyse the characteristics and long-term outcome of these patients. All chest and pathological departments of teaching hospitals in Paris were contacted in order to identi...
We present a case of a 45-year-old woman with primary Sjögren's syndrome, who in 2005, one year after the onset of the systemic autoimmune disease developed chronic lymphocytic leukaemia, which eventually transformed denoted as Richter’s transformation into diffuse large B-cell lymphoma in 2006. She had recurrent lymphadenopathy on the neck region from 2002. In September 2005 anaemia and elevat...
2-[N'-2-Pyrimidyl-aminobenzenesulfonamido] ethyl 4-bis(2-chloroethyl) aminophenyl butyrate has been prepared by reaction of chlorambucil with sulfadiazine derivative. Schiffs base has been used as the protective group of the aromatic amine in the synthesis. It can be completely removed by the irradiation of 365 nm UV light at room temperature. The title compound exhibits a high antitumor activi...
Various mechanisms have been implicated in nitrogen mustard drug resistance. The role of these mechanisms in the development of chlorambucil drug resistance in chronic lymphocytic leukemia (CLL) is discussed. We review these mechanisms with emphasis on the emerging role of DNA repair, and specifically, recombinational repair. Inhibition of these repair processes may lead to new therapies, not o...
A revolutionary approach to air defense has been extensively evaluated recently. The approach is a new Cooperative Engagement Capability (CEC) that allows combat systems to share unfiltered sensor measurements data associated with tracks with rapid timing and precision to enable the battlegroup units to operate as one. The CEC system and the program for Fleet introduction are described. Further...
We studied the influence of signal variability on human and model observers for detection tasks with realistic simulated masses superimposed on real patient mammographic backgrounds and synthesized mammographic backgrounds (clustered lumpy backgrounds, CLB). Results under the signal-known-exactly (SKE) paradigm were compared with signal-known-statistically (SKS) tasks for which the observers di...
