The fortification of cereal grains with metal micronutrients is a major target to combat human malnutrition of Fe and Zn. Based on recent studies showing that N fertilization can promote Fe and Zn accumulation in cereal grains, we investigated here the influence of nitrate- or ammonium-based N fertilization on the accumulation of Fe, Zn, and Cu as well as metal chelator pools in flag leaves and...

We have run a set of experiments in the CLOUD chamber at CERN, Switzerland, studying the effect of dimethylamine (DMA) on sulfuric acid (SA)-water nucleation using a nitrate based Chemical Ionization Atmospheric Pressure ionization Time-Of-Flight Mass Spectrometer (CI-APiTOF). Experiment was designed to produce neutral high m/z SA-DMA clusters in close to atmospherically relevant conditions to ...

In vitro modification of M13 phage single-stranded DMA with 4-hydroxyaminoquinoline 1-oxide (4HAQO) resulted in four kinds of adducts: three guanine adducts, QGh QGn, and QGm;and one adenine adduci, QA, at ratios of 16.4 47.3, 13.7, and 22.6, respectively. The carcinogen-modified DMA, initiated with a se quence-defined oligodeoxynucleotide primer, was replicated in vitro with Escherichia coli D...

Here, we report the identification of dimethylarsinothioyl glutathione (DMMTA(V)(GS)) as a metabolite in cellular extracts of dimethyarsinous glutathione (Darinaparsin, DMA(III)(GS)) treated human multiple myeloma (MM) cell lines. Co-elution of sulfur and arsenic on the inductively coupled plasma mass spectrometer (ICP-MS) indicated the presence of sulfur along with arsenic in the newly observe...

Executive Summary Based on studies in rats, it is clear that the mode of action (MOA) for DMA V-induced bladder tumors is cytotoxicity, resulting in persistent regenerative proliferation, leading to development of bladder tumors. This MOA has no mutagenic component and has a nonlinear dose response. The toxicokinetics of DMA V is different from the toxicokinetics of DMA V in other species, incl...

We propose FlexNIC, a flexible network DMA interface that can be used by operating systems and applications alike to reduce packet processing overheads. The recent surge of network I/O performance has put enormous pressure on memory and software I/O processing subsystems. Yet even at high speeds, flexibility in packet handling is still important for security, performance isolation, and virtuali...

We report charge-switching ionic nanocomplexes comprised of glycol chitosan grafted with 2,3-dimethylmaleic acid (DMA) (denoted as 'GCS-g-DMA' hereafter) and a proapoptotic peptide. This system allowed for improved peptide delivery to tumor sites via a mechanism of selective peptide release when the pH was dropped from 7.4 to 6.8.

We present ongoing work on applying model checking techniques to automatically analyse multicore software where data is managed explicitly by the programmer via direct memory access (DMA) operations. We describe SCRATCH, a DMA race analysis tool for the Cell BE processor which employs bounded model checking and k-induction. We then outline our plans to extend this work.
