Raftery, Kárnỳ, and Ettler (2010) introduce an estimation technique called Dynamic Model Averaging (DMA). In their application, DMA is used to the problem of predicting the output strip thickness for a cold rolling mill, where the output is measured with a time delay. Recently, DMA has also shown to be very useful in macroeconomic and financial applications. In this paper, we present the eDMA p...

Fullerene (C60) has shown great potential in drug delivery. In this study we exploited modified fullerene (diadduct malonic acid-fullerene-Asn-Gly-Arg peptide [DMA-C60-NGR]) as an antitumor drug carrier in order to build a new tumor-targeting drug delivery system. We also investigated the synergistic enhancement of cancer therapy using photodynamic therapy (PDT) induced by DMA-C60-NGR and 2-met...

A series of three-dimensional (3D) extended metal catecholates (M-CATs) was synthesized by combining the appropriate metal salt and the hexatopic catecholate linker, H6THO (THO(6-) = triphenylene-2,3,6,7,10,11-hexakis(olate)) to give Fe(THO)·Fe(SO4) (DMA)3, Fe-CAT-5, Ti(THO)·(DMA)2, Ti-CAT-5, and V(THO)·(DMA)2, V-CAT-5 (where DMA = dimethylammonium). Their structures are based on the srs topolo...

Hundreds of millions of people worldwide are exposed to unacceptable levels of arsenic in drinking water. This is a public health crisis because arsenic is a Group I (proven) human carcinogen. Human cells methylate arsenic to monomethylarsonous acid (MMA), monomethylarsonic acid (MMA), dimethylarsinous acid (DMA), and dimethylarsinic acid (DMA). Although the liver is the predominant site for ar...

Thio-dimethylarsinic acid (thio-DMA(V)) has recently been identified as human metabolite after exposure toward both the human carcinogen inorganic arsenic and arsenosugars, which are the major arsenical constituents of marine algae. This study aims to get further insight in the toxic modes of action of thio-DMA(V) in cultured human urothelial cells. Among others effects of thio-DMA(V) on eight ...

The feasibilities of two strategies for the simultaneous analysis of five carbamate insecticides (i.e. propoxur, carbofuran, carbaryl, isoprocarb, and promecarb) by high performance liquid chromatography (HPLC) have been investigated. The first method is the preconcentration strategy based on micelle-mediated extraction (MME) using sodium dodecyl sulfate. The second strategy uses chemical deriv...

Based on the ability of phytosiderophores to chelate other heavy metals besides iron (Fe), phytosiderophores were suggested to prevent graminaceous plants from cadmium (Cd) toxicity. To assess interactions between Cd and phytosiderophore-mediated Fe acquisition, maize (Zea mays) plants were grown hydroponically under limiting Fe supply. Exposure to Cd decreased uptake rates of 59Fe(III)-phytosi...

Radiotherapy, a therapeutic modality of cancer treatment, nonselectively damages normal tissues as well as tumor tissues. The search is ongoing for therapeutic agents that selectively reduce radiation-induced normal tissue injury without reducing tumoricidal effect, thereby increasing the therapeutic ratio of radiation therapy. Our laboratory established 5-(4-methylpiperazin-1-yl)-2-[2'-(3,4-di...

A DMA controller that operates in the cycle-stealing mode transfers data by stealing bus cycles from the CPU. The concurrent contention for the I/O bus by a CPU task and a cycle-stealing DMA I/O task retards their progress and extends their execution times. In this paper we first describe a method for bounding the worst-case execution time (WCET) of a CPU task when cycle-stealing DMA I/O is pre...

A commercially available direct mercury analyzer (DMA) based on sample combustion, pre-concentration by amalgamation with gold, and atomic absorption spectrophotometry (AAS) was coupled to a sector field inductively coupled plasma mass spectrometer (ICP-MS). The combined system (DMA-ICP-MS) was optimized and evaluated for the determination of mercury in environmental samples using both external...
