A Brief History of Phytochromes
Authors: Rockwell Nathan C. , Lagarias J. Clark 
Published: February 2010

AbstractPhotosensory proteins enable living things to detect the quantity and quality of the light environment and to transduce that physical signal into biochemical outputs which entrain their metabolism with the ambient light environment. Phytochromes, which photoconvert between red‐absorbing Pr and far‐red‐absorbing Pfr states, are the most extensively studied of these interesting proteins. Critical regulators of a number of key adaptive processes in higher plants, including photomorphogenesis and shade avoidance, phytochromes are widespread in photosynthetic and nonphotosynthetic bacteria, and even in fungi. Cyanobacterial genomes also possess a plethora of more distant relatives of phytochromes known as cyanobacteriochromes (CBCRs). Biochemical characterization of representative CBCRs has demonstrated that this class of photosensors exhibits a broad range of wavelength sensitivities, spanning the entire visible spectrum. Distinct protein–bilin interactions are responsible for this astonishing array of wavelength sensitivities. Despite this spectral diversity, all members of the extended family of phytochrome photosensors appear to share a common photochemical mechanism for light sensing: photoisomerization of the 15/16 double bond of the bilin chromophore.
NorthernLights in slide‐based cytometry and microscopy

Published: February 2010

AbstractIn recent years, slide‐based cytometry has become a key technology for polychromatic cytometric investigations, and many efforts have been made to increase the number of measurable fluorochromes for multiparametric analysis. Sequential photobleaching of fluorochromes next to very photostable dyes is one approach for this technology. As the ALEXA dyes are known to be photostable as compared to the conventional fluorochromes FITC, PE (Riggs et al., Am J Pathol 1958;34:1081–1097), and APC, a differentiation within a fluorochrome pair is possible. Here, we have analyzed the newly available NorthernLights™ secondary antibodies for use in slide‐based cytometry and microscopy. Currently, these fluorochrome‐conjugates are now available with three distinct excitation‐ and emission maxima (NL493, NL557, NL637). Their spectral properties are similar to the frequently used fluorochromes FITC, PE, and APC and can, therefore, be used with most common excitation sources of cytometers or microscopes. As the NorthernLights™ are bright, resistant to photobleaching, stable in alcohols and xylene and of affordable price, these dyes are promising candidates for use with most laser‐ and HBO/XBA‐based fluorescence microscopy‐like techniques. © 2010 International Society for Advancement of Cytometry
N‐acetylcysteine impairs survival of luteal cells through mitochondrial dysfunction
Authors: Löhrke Berthold , Xu Jinxian , Weitzel Joachim M. , Krüger Burkhard , Goldammer Tom , Viergutz Torsten 
Published: February 2010

AbstractN‐acetylcysteine (NAC) is known as an antioxidant and used for mucus viscosity reduction. However, this drug prevents or induces cell death depending on the cell type. The response of steroidogenic luteal cells to NAC is unknown. Our data shows that NAC can behave as an antioxidant or prooxidant in dependency on the concentration and mitochondrial energization. NAC elevated the flowcytometric‐measured portion of hypodiploid (dying) cells. This rise was completely abolished by aurintricarboxylic acid, an inhibitor of topoisomerase II. NAC increased the secretion of nitric oxide and cellular nitrotyrosine. An image analysis indicated that cells pretreated with NAC and loaded with DHR showed a fluorescent structure probably elicited by the oxidative product of DHR, rhodamine 123 that sequesters mitochondrially. Pretreating luteal cells with NAC or adding NAC directly to mitochondrial fractions followed by assessing the mitochondrial transmembrane potential difference (Δψ) by the JC‐1 technique demonstrated a marked decrease in Δψ. A protonophore restored Δψ and rotenone (an inhibitor of respiratory chain complex I) inhibited mitochondrial recovering. Thus, in steroidogenic luteal cells from healthy mature corpus luteum, NAC impairs cellular survival by interfering with mitochondrial metabolism. The protonophore‐induced recovering of NAC‐provoked decrease in Δψ indicates that an ATP synthase‐favored route of H+ re‐entry to the matrix is essentially switched off by NAC while other respiratory chain complexes remain intact. These data may be important for therapeutic timing of treatments with NAC. © 2010 International Society for Advancement of Cytometry
The proto‐oncogene BCL6 promotes survival of olfactory sensory neurons
Authors: Otaki Joji M. , Hatano Masahiko , Matayoshi Rie , Tokuhisa Takeshi , Yamamoto Haruhiko 
Published: February 2010

AbstractFor the mammalian olfactory epithelium to continually detect odorant, neuronal survival, apoptosis, and regeneration must be coordinated. Here, we showed that the proto‐oncogene BCL6, which encodes a transcriptional repressor required for lymphocyte terminal differentiation, contributes to the survival of olfactory sensory neurons (OSNs). In the olfactory epithelia of the BCL6 null mutant mice, many OSNs were positive for both OMP and GAP43. The epithelium was relatively thinner, showing many apoptotic signals. These characters were phenotypically similar to those of the wild‐type mice treated with nasal lectin irrigation, which acutely induces apoptosis of OSNs. Odorant receptors were expressed normally in the epithelia of the mutant mice, and their overall expression profile based on DNA microarray analyses was roughly similar to that of the apoptosis‐induced olfactory epithelia of the wild‐type mice. Experimental increase of BCL6 together with green fluorescent protein in OSNs using adenovirus‐mediated gene transfer made the epifluorescence last longer than the control fluorescence without exogenous BCL6 after the nasal lectin irrigation, indicating that BCL6 made the infected neurons survive longer. We conclude that BCL6 plays an active role in the survival of OSNs as an anti‐apoptotic factor and confers immature OSNs enough time to fully differentiate into mature ones. © 2010 Wiley Periodicals, Inc.

Published: February 2010

AbstractA novel three‐component reaction between 1‐substituted imidazoles, aldehydes, and electron‐deficient acetylenes proceeds under mild conditions (20–25 °C, no catalyst, no solvent) to form an unknown family of C2‐functionalized imidazoles in up to 74 % yield, the function constituting a push–pull combination of enol ether and acrylic moieties. In the case of cyanophenylacetylene, the function is built up stereospecifically to have the (Z) configuration. The interaction presumably occurs via zwitterion and carbene intermediates. The results contribute to basic imidazole and acetylene chemistry and open a shortcut to promising drug candidates.
Hydroselenation and Carboselenation of Electron‐Deficient Alkynes with Isolable (Hydrido)(selenolato)platinum(II) Complexes and a Selenaplatinacycle Bearing a Triptycene Skeleton

Published: February 2010

AbstractThe reaction of [PtH(SeTrip)(PPh3)2] (Trip = 9‐triptycyl) (3) with dimethyl acetylenedicarboxylate (DMAD) or methyl propiolate gave hydroselenation syn adducts. The reaction of [PtH(SeTrip)(dppe)] [dppe = 1,2‐bis(diphenylphosphanyl)ethane], which has a stronger phosphane σ‐donor ligand than 3, with DMAD gave both syn and anti adducts. The reaction of 3 and DMAD in the presence of PPh3 yielded no adducts. These observations indicate that, in the hydroselenation, the dissociation of a PPh3 ligand from 3 is a key step. The selenaplatinacycle 6, which is a thermal reaction product of 3, reacted with DMAD to give the carboselenation product, 1H‐2‐benzoselenin 7, which was also formed by the reaction of TripSeH with DMAD.
The Determination of Methanol Using an Electrolytically Fabricated Nickel Microparticle Modified Boron Doped Diamond Electrode

Published: February 2010

AbstractA nickel modified boron doped diamond (Ni‐BDD) electrode and nickel foil electrode were used in the determination of methanol in alkaline solutions. The Ni‐BDD electrode was electrodeposited from a 1 mM Ni(NO3)2 solution (pH 5), followed by repeat cycling in KOH. Subsequent analysis utilised the Ni(OH)2/NiOOH redox couple to electrocatalyse the oxidation of methanol. Methanol was determined to limits of 0.3 mM with a sensitivity of 110 nA/mM at the Ni‐BDD electrode. The foil electrode was less sensitive achieving a limit of 1.6 mM and sensitivity of 27 nA/mM. SEM analysis of the electrodes found the Ni‐BDD to be modified by a quasi‐random microparticle array.

Published: February 2010

AbstractThe key operating characteristics of biofuel cells, high energy density and low power delivery, make them ideal power choices for military, industrial, and niche wireless sensor network applications. There is virtually universal demand for higher energy power supplies for wireless sensors to enable longer operation, more frequent data capture, and higher bandwidth sensing techniques such as video. Advanced biofuel cell technology has been demonstrated for such applications that is capable of 2–4×increase in energy density compared to incumbent batteries of a similar size.
Metal(II)–ligand molar ratio dependence of enantioseparation of tartaric acid by ligand exchange CE with Cu(II) and Ni(II)–D‐quinic acid systems

Published: February 2010

AbstractEnantioseparation of tartaric acid by ligand exchange CE with a Cu(II)–D‐quinic acid system was studied. Racemic tartaric acid was enantioseparated by ligand exchange CE using BGEs containing relatively low Cu(II)–D‐quinic acid molar ratios ranging from 1:1 to 1:3 and high molar ratios ranging from 1:8 to 1:12 but was not enantioseparated using BGEs with medium molar ratios ranging from 1:4 to 1:6. While the migration order of D‐tartaric acid was prior to L‐tartaric acid at the lower Cu(II)–D‐quinic acid molar ratios, the enantiomer migration order was reversed at the higher molar ratios. These results were compared with those for Ni(II)–D‐quinic acid system. The molar ratio dependence of enantiomer migration order can be attributed to a change in the coordination structure of Cu(II) ion with D‐quinic acid.
An idealised model of turbulent dispersion: two and three spatial dimensions
Authors: Mole Nils 
Published: February 2010

AbstractIn the idealised model of turbulent dispersion introduced by Zimmerman and Chatwin (1995), the probability density function (pdf) of concentration becomes bimodal at large times, with peaks at the smallest and largest concentrations. That model only has one spatial dimension, but here I extend the model to two and three spatial dimensions. I also extend to two and three dimensions the pdf calculation method that was given by Mole and Yeun (2007). I use this method to derive large‐time analytical solutions for the pdf, and to show that in two and three dimensions the weight of the pdf shifts from extreme concentrations towards the mean concentration. In the typical three‐dimensional case, the large‐time pdf is unimodal with the peak at the mean concentration. Copyright © 2010 John Wiley & Sons, Ltd.
Change point analysis of extreme values
Authors: Dierckx G. , Teugels J. L. 
Published: February 2010

AbstractIn a sample from the distribution of a random variable, it is possible that the tail behavior of the distribution changes at some point in the sample. This tail behavior can be described by absolute or relative excesses of the data over a high threshold, given that the random variable exceeds the threshold. The limit distribution of the absolute excesses is given by a generalized Pareto distribution with an extremal parameter γ and a scale parameter σ. When the extreme value index γ is positive, then the relative excesses can be described in the limit by a Pareto distribution with this index as parameter.In this paper we concentrate on testing whether changes occur in the value of the extreme value index γ and/or the scale parameter. To this end, appropriate test statistics are introduced based on the likelihood approach for independent data. Asymptotic properties of these test statistics are studied leading to adequate critical values. After giving a practical test procedure, we apply our results to a series of simulations and real life examples. Copyright © 2010 John Wiley & Sons, Ltd.
Triclosan has endocrine-disrupting effects in male western mosquitofish,Gambusia affinis
Authors: Raut Samiksha A. , Angus Robert A. 
Published: February 2010

AbstractTriclosan (TCS) is an antibacterial agent used in a variety of personal care and industrial products. Triclosan and its environmentally transformed derivative, methyl-TCS, have been detected in waters receiving effluent from public wastewater treatment plants. Previous studies have demonstrated that TCS has the potential to act as an endocrine disruptor. The present study tested the hypothesis that TCS acts as an endocrine-disrupting agent in fish. Mature male western mosquitofish, Gambusia affinis, were exposed to TCS concentrations of 100, 200, and 350 nM (29.0, 57.9, and 101.3 µg/L) for 35 d by the static renewal method. Induction of the normally female-limited vitellogenin gene expression and reduction in sperm count were quantified as biomarkers of endocrine disruption. Vitellogenin mRNA expression was significantly elevated in the 350 nM TCS treatment. Sperm counts in the same treatment group were significantly decreased. The mean hepatosomatic index in the 350 nM treatment group was significantly increased. This study demonstrates that TCS has the potential to act as an endocrine disruptor in male mosquitofish.

Population models in pesticide risk assessment: Lessons for assessing population-level effects, recovery, and alternative exposure scenarios from modeling a small mammal
Authors: Wang Magnus , Grimm Volker 
Published: February 2010

Abstract
In the last few years, the interest in using ecological population models as a tool for pesticide risk assessment has increased rapidly. Practical guidance, however, on how to perform a risk assessment with a population model is still lacking. It is still unclear which endpoint (population density, population growth, etc.) is the most sensitive indicator of population-level effects and how risk can be evaluated at the population level. Moreover, a main added value of model-based risk assessments, which is an understanding of the mechanisms involved in alternative exposure scenarios, so far has received little attention. We therefore used an example model to compare commonly used endpoints and alternative exposure scenarios. The model is a structurally realistic, but relatively simple, individual-based, spatially explicit model for the common shrew (Sorex araneus), which was selected because it has been tested and validated extensively. We show that population density is more sensitive for detecting population-level effects in the short term (months) than population growth rate. Population viability measured by extinction risk can also be a relevant endpoint, because it is especially sensitive for small populations. We show that landscape structure and the timing of pesticide application (population structure at the time of application) can have a great impact on population recovery, and we analyze statistical tests for use in population-level risk assessments. Our results demonstrate which factors and insights should be taken into account in population-level risk assessments. Environ. Toxicol. Chem. 2010;29:1292–1300. © 2010 SETAC
