The budding yeast protein Chl1p is required to preserve genome integrity upon DNA damage in S-phase
(OXFORD UNIV PRESS, 2006-11)The budding yeast protein, Chl1p, is required for sister-chromatid cohesion, transcriptional silencing, rDNA recombination and aging. In this work, we show that Chl1p is also required for viability when DNA replication is ... -
Antimitotic sulfonamides inhibit microtubule assembly dynamics and cancer cell proliferation
(AMER CHEMICAL SOC, 2006-08-01)Several sulfonamides have antitumor activities and are currently undergoing clinical evaluation for the treatment of cancer. In this study, we have elucidated the antiproliferative mechanism of action of five indole ... -
Dielectric relaxation in perovskite BaAl1 / 2 Nb1 / 2 O3
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-07-01)The complex perovskite oxide barium aluminium niobate, BaAl1/2Nb1/2O3 (BAN) is synthesized by a solid-state reaction technique for the first time. The X-ray diffraction of the sample at room temperature shows a monoclinic ... -
Oxalone and lactone moieties of podophyllotoxin exhibit properties of both the B and C rings of colchicine in its binding with tubulin
(AMER CHEMICAL SOC, 2006-05-23)Thermodynamics of podophyllotoxin binding to tubulin and its multiple points of attachment with tubulin has been studied in detail using isothermal titration calorimetry. The calorimetric enthalpy of the association of ... -
Analyzing powers and spin correlation coefficients for p+d elastic scattering at 135 and 200 MeV
(AMERICAN PHYSICAL SOC, 2006-12-01)The proton and deuteron analyzing powers and ten of the possible 12 spin correlation coefficients have been measured for p+d elastic scattering at proton bombarding energies of 135 and 200 MeV. The results are compared ... -
Investigations on compton scattering: New directions
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-12-01)Although inelastic (Compton) scattering of a photon off a free electron was well understood about 80 years ago, inelastic scattering off bound electrons remains an incompletely understood process. The availability of ... -

Radiation detection by using superheated droplets
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-11-01)The superheated emulsion, a radiation detector consisting of superheated droplets dispersed in a gel or a solid matrix, has been in use for some time now. It was initially designed to detect neutrons but also has been ... -
GM2 expression in renal cell carcinoma: Potential role in tumor-induced T-cell dysfunction
(AMER ASSOC CANCER RESEARCH, 2006-07-01)Multiple mechanisms have been proposed to account for immune escape by tumors. Although gangliosides have long been known to suppress T-cell immunity, few studies have examined the effect of human tumor-derived gangliosides ... -
Quantum superarrivals: Bohr's wave-particle duality revisted
(SPRINGER/PLENUM PUBLISHERS, 2006-04-01)The phenomenon of quantum superarrivals is manifested in the probabilities for Schrodinger wave packets scattered from perturbed potential barriers. We argue that both classical wave-like and classical particle-like ... -
Overcoming drug-resistant cancer by a newly developed copper chelate through host-protective cytokine-mediated apoptosis
(AMER ASSOC CANCER RESEARCH, 2006-07-15)Purpose: Previously, we have synthesized and characterized a novel Cu(II) complex, copper N-(2-hydroxyacetophenone) glycinate (CuNG). Herein, we have determined the efficacy of CuNG in overcoming multidrug-resistant cancer ... -
Immunosuppression, hepatotoxicity and depression of antioxidant status by arecoline in albino mice
