The urinary metabolites of 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT), 1,1-dichloro-2,2-bis(p-chlorophenyl)ethane (ODD), and 1-chloro-2,2-bis(p-chlorophenyl)ethene in female hamsters are reported. The principal metabolite of both DDT and ODD is 2,2-bis(p-chlorophenyl) acetic acid. DDTand DDDtreated animals also excreted small amounts of DDD, 1-chloro2,2-bis(p-chlorophenyl)ethene, 1,1 -...

Abstract This chapter introduces a general protocol to transfer metal ions from aqueous solution to an organic medium, which involves mixing the aqueous solution of metal ions with an ethanolic solution of dodecylamine (DDA), and extracting the coordinating compounds formed between metal ions and DDA into toluene. This protocol could be applied toward transferring a wide variety of transition m...

The objective of this study was to obtain better antigen specific cytotoxic T cell responses in vivo. We examined the augmented induction of antigen-specific cytotoxic T cell responses to co-administration of oligonucleotides (CpG-ODN), dimethyl dioctadecyl ammonium bromide (DDA), and Lipofectamine™ 2000 with a DNA vaccine (pVAX1-CpG-Loop) and boosting with pVAX1-CpG-Loop in BALB/c mice. The re...

Diffusion-time distribution analysis (DDA) has been used to explore the plasma membrane fluidity of multidrug-resistant cancer cells (LR73 carcinoma cells) and also to characterize the influence of various membrane agents present in the extracellular medium. DDA is a recent single-molecule technique, based on fluorescence correlation spectroscopy (FCS), well suited to retrieve local organizatio...

Two Ag(I) ions, deprotonated 1-methyl-thymine (1MT-H)(-) and 1,3-dideaza-adenine (DDA), self-assemble in methanolic solution to a cationic [(Ag)2(1MT-H)(DDA)](+) complex as identified by electrospray ionization mass spectrometry. Assignment of vibrational bands and identification of the silver coordination pattern arise from comparison of one- and two-color Infrared Multiple Photon Dissociation...

Nanosized rare earth (RE) hydroxides including La(OH)3, Nd(OH)3, Pr(OH)3, Sm(OH)3, Gd(OH)3, and Er(OH)3 with rod-like morphology are fabricated via a convenient hydrothermal approach. This strategy calls for the first preparation of metal complexes between RE precursors and dodecylamine (DDA) in water/ethanol mixture at room temperature and subsequent thermal decomposition at elevated temperatu...

Recent times have seen an upsurge in interest in the area of “inclusive design” within which access to the built environment has enjoyed a prominent position. There are a number of factors providing the impetus for this, not least a growing awareness of the quality issues incumbent in inclusivity but also there is evidence of a response to the threat of the impending legislation within the Disa...

Traditionally, direct implementation of a K-tap FIR filter requires K multiply-and-accumulate (MAC) blocks, which are expensive to implement in FPGA due to logic complexity and resource usage. To resolve this issue, we first present DA, which is a architecture without multiplier. This paper implements the DA architecture. This architecture is applicable to only one type of filter Coefficients i...

Nanocrystals prepared in organic media can be easily self-assembled into close-packed hexagonal monolayers on solvent evaporation for various applications. However, they usually rely on the use of organometallic precursors that are soluble in organic solvents. Herein we report a general protocol to transfer metal ions from an aqueous solution to an organic medium, which involves mixing the aque...

Delays in biological systems may be used to model events for which the underlying dynamics cannot be precisely observed, or to provide abstraction of some behavior of the system resulting in more compact models. Deterministic modeling of biological systems with delays is usually based on Delay Differential Equations (DDes), an extension of ordinary ones where the derivative of the unknown funct...
