Checkpoint deficient rad53-11 yeast cannot accumulate dNTPs in response to DNA damage
Deoxyribonucleotide pools are maintained at levels that support efficient and yet accurate DNA replication and repair. Rad53 is part of a protein kinase regulatory cascade that, conceptually, promotes dNTP accumulation in ...
Regulation of mRNA stability through a pentobarbital-responsive element
Pentobarbital, a general anesthetic and non-genotoxic carcinogen, can induce gene expression by activating transcription. In the Drosophila glutathione S-transferase D21 (gstD21) gene, pentobarbital's regulatory influence ...
Assessment of the molecular weight distribution of tannin fractions through MALDI-TOF MS analysis of protein-tannin complexes
(American Chemical Society, 2007-03)
An innovative mass spectrometry method was developed for determining mass distributions of tannin fractions that cannot be approached through direct MALDI-TOF analysis. It was applied to three procyanidin fractions with ...
Dissipative hierarchies and resonance solitons for KP-II and MKP-II
We show that dissipative solitons (dissipatons) of the second and the third members of SL(2,R) AKNS hierarchy give rise to the real solitons of KP-II, while for SL(2,R) Kaup-Newell hierarchy they give solitons of MKP-II. ...
Dependence of Josephson junction critical current on the deposition rate of YBa2Cu3O7-δ thin films
(American Institute of Physics Publising, 2007)
We have reported the effect of YBa2Cu3O 7-δ (YBCO) thin film deposition rate on the 24 and 30 degree STO bicrystal Josephson junctions critical currents by fabricating series of junctions with different deposition rates. ...
Upregulation of multi drug resistance genes in doxorubicin resistant human acute myelogeneous leukemia cells and reversal of the resistance
(Taylor & Francis, 2007-12)
The major problem in the treatment of acute myeloid leukemia (AML) patients results from multidrug resistance to administered anticancer agents. Drug resistance proteins, MDR1 and MRP1, which work as drug efflux pumps, can ...
Investigation of the effect of thermal cycling on the device performance of YBa2Cu3O7-δ DC-SQUIDs
(IOP Publishing, 2007-10)
We investigated the effect of thermal cycling on the operational performance of YBa2Cu3O7-δ (YBCO) direct current superconducting quantum interference devices (DC-SQUIDs) fabricated onto 24°SrTiO3 (STO) bicrystal substrates. ...
MgB2 superconducting thin films sequentially fabricated using DC magnetron sputtering and thermionic vacuum arc method
In this work, we discuss fabrication and characterization of MgB2 thin films obtained by sequential deposition and annealing of sandwich like Mg/B/Mg thin films on glass substrates. Mg and B films were prepared using DC ...

Effect of humidity on electrical conductivity of zinc stearate nanofilms
In this work, stearic acid (StAc) and zinc stearate (ZnSt2) nanofilms were deposited on glass and silver substrates using Langmuir-Blodgett (LB) film technique and their structural and electrical properties were investigated. ...
