Magnetic resonance spectroscopy (MRS) and its application in Alzheimer's disease
Authors: Mandal Pravat K. 
Published: January 2007

AbstractMagnetic resonance spectroscopy (MRS) is a noninvasive tool to measure the chemical composition of tissues (in vivo) and characterize functional metabolic processes in different parts of the human organs. It provides vital biological information at the molecular level. Combined with magnetic resonance imaging (MRI), an integrated MRI/MRS examination provides anatomical structure, pathological function, and biochemical information about a living system. MRS provides a link between the biochemical alterations and the pathophysiology of disease. This article provides a comprehensive description of the MRS technique and its application in Alzheimer's disease (AD) research. This review is a primer for students and researchers seeking a firm theoretical understanding of MRS physics as well as its application in clinical AD research. © 2007 Wiley Periodicals, Inc.

Quinoline antimalarials as investigational drugs for HIV‐1/AIDS: in vitro effects on HIV‐1 replication, HIV‐1 response to antiretroviral drugs, and intracellular antiretroviral drug concentrations
Authors: Savarino Andrea , Lucia Mothanje B. , ter Heine Rob , Rastrelli Elena , Rutella Sergio , Majori Giancarlo , Huitema Alwin , Boelaert Johan R. , Cauda Roberto 
Published: January 2007

AbstractIn this study, the effects of the quinoline antimalarials, chloroquine and mefloquine, were tested on: (1) HIV‐1 replication; (2) virus response to existing antiretrovirals; (3) functional activity of drug efflux pumps; and (4) intracellular accumulation of antiretrovirals. Antiretroviral activity was evaluated using cells acutely infected with drug‐sensitive/resistant HIV‐1 isolates or retroviral vectors, chronically infected cell lines, and syncytium assays. Drug interactions were assessed isobolographically. Activity of efflux pumps was tested using specific fluorochromes. Antitretroviral concentrations were quantitated by HPLC. Results indicated that: (1) the antimalarials (mefloquine > chloroquine) inhibited the replication of drug‐sensitive and drug‐resistant HIV‐1 at therapeutically achievable concentrations and specifically impaired the formation of fusion‐competent viral glycoproteins; (2) anti‐HIV‐1 effects were additive to those of zidovudine and nevirapine, and synergistic to those of lopinavir; (3) the antimalarials (mefloquine > chloroquine) inhibited the P‐glycoprotein, multidrug‐resistance‐associated proteins, and breast‐cancer resistance‐associated protein; (4) Chloroquine, but not mefloquine, increased lopinavir concentrations in peripheral blood mononuclear cells (PBMCs) by approximately 5 (five)‐fold. Thus quinoline antimalarials inhibited HIV‐1 replication by a novel mechanism, resulting in additive or synergistic effects in combination with known antiretrovirals. These drugs may also have an impact on the cellular pharmacokinetics of antiretrovirals. Drug Dev. Res. 67:806–817, 2006. © 2007 Wiley‐Liss, Inc.
A green to red photoconvertible protein as an analyzing tool for early vertebrate development
Authors: Wacker Stephan A. , Oswald Franz , Wiedenmann Jörg , Knöchel Walter 
Published: January 2007

AbstractTracking of cells during early development of Xenopus laevis using the green‐to‐red photoconvertible protein EosFP. The GFP‐like fluorescent protein EosFP was recombinantly expressed in a bacterial system. The purified protein was microinjected in the 2 dorsal blastomeres at stage 3 (uppermost, left). Photoconversion of EosFP from the green to the red fluorescent form was induced in the right blastomere by irradiation with ˜420 nm‐light under the fluorescence microscope (second from above). The descending cells can be tracked by their red fluorescent during the following development. Injection of EosFP‐coding mRNA produces a gap in detectability for the time required for expression and maturation of the fluorescent protein. In contrast, microinjection of purified EosFP allows to exploit the benefits of regional optical marking immediately. See Wacker et al., Developmental Dynamics 236:473–480.
Optimization of spatiotemporal gene inactivation in mouse heart by oral application of tamoxifen citrate
Authors: Kiermayer Claudia , Conrad Marcus , Schneider Manuela , Schmidt Jörg , Brielmeier Markus 
Published: January 2007

AbstractInducible and tissue‐specific gene inactivation in mice has become a powerful tool to bypass embryonic and postnatal lethality of knockout mice. The most frequently used inducible system is based on Cre recombinase fused to either one or two mutated estrogen receptor ligand binding domains, thus rendering Cre function tamoxifen‐dependent. To achieve Cre‐mediated inactivation of a given gene, 4‐OH tamoxifen (4‐OHT) dissolved either in alcohol and/or oil is usually administered by repeated intraperitoneal (i.p.) injections. Since this procedure imposes considerable stress on mice, we compared the effect of tamoxifen citrate, mixed into a standard mouse diet at different concentrations, with that of i.p. administration of 4‐OHT on Cre‐mediated, heart‐specific inactivation of thioredoxin reductase 2. Here we show that tamoxifen citrate in the chow was equally effective as 4‐OHT given i.p. Oral tamoxifen administration is thus a convenient and cost‐saving way for gene induction, and, most importantly, it reduces stress and avoids adverse effects in mice. genesis 45:11–16, 2007. © 2007 Wiley‐Liss, Inc.
Synthesis of Novel Vinylic P–Se Heterocycles from Selenation of Alkynes by [PhP(Se)(μ‐Se)]2
Authors: Hua Guoxiong , Li Yang , Slawin Alexandra M. Z. , Woollins J. Derek 
Published: January 2007

AbstractEleven novel five‐membered PSe2C2 heterocycles have been synthesised from [PhP(Se)(μ‐Se)]2 (Woollins' reagent) and alkynes (one or two C≡C triple bonds) by insertion of a Ph(Se)PSe2 fragment into alkyne triple bonds. An unusual diselenide formed by an intramolecular cycloaddition/rearrangement is also reported. All compounds have been characterised spectroscopically and four demonstrative X‐ray crystal structures are reported. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
Rapid Sequencing of Split‐and‐Mix Peptide Receptor Libraries – Identification of Binding Partners for Val‐Val‐Ile‐Ala in Aqueous Solution
Authors: Shepherd Jon , Langley G. John , Herniman Julie M. , Kilburn Jeremy D. 
Published: January 2007

AbstractSplit‐and‐mix peptide libraries have been encoded by capping cleavable, laddered sequences with p‐bromobenzoic acid, allowing rapid analysis of the cleaved ladder fragments by mass spectrometry. The encoding methodology has been applied to the synthesis of libraries of peptide receptors and a library of tripeptides functionalised with a bicyclic guanidinium unit has been successfully screened to identify binding partners for Val‐Val‐Ile‐Ala, the C‐terminal tetrapeptide sequence of the amyloid‐β protein, Aβ(1–42).
