Platelet microparticles are heterogeneous and highly dependent on the activation mechanism: Studies using a new digital flow cytometer
Authors: Perez‐Pujol Sílvia , Marker Paul H. , Key Nigel S. 
Published: January 2007

AbstractBackground:Platelet‐derived microparticles (MPs) are believed to play an important role in coagulation and inflammatory disorders. Unfortunately, MP size renders them difficult to study and analyze by conventional flow cytometry.Methods:We analyzed and characterized platelet‐derived MPs, using antibodies against the major surface glycoproteins (GP), the platelet activation antigen P‐selectin (CD62P), and a marker of procoagulant activity (phosphatidylserine exposure). MPs were generated by exposure of platelets to thrombin receptor activating peptide (TRAP) or ionophore. Both agonists induced significant microvesiculation of platelets, and the resulting MPs were analyzed by a new digital flow cytometer: Becton‐Dickinson FACSAria™.Results:Membrane GPs were equally well represented in MPs generated by either reagent. In contrast, P‐selectin was more intensely expressed in TRAP‐MPs, while phosphatidylserine (PS) expression was markedly increased in ionophore‐MPs. Two distinct populations of TRAP‐MPs (one PS‐positive and another PS‐negative) were apparent. The latter characteristic facilitated sorting of MPs according to their PS exposure.Conclusions:The data presented herein show a significant improvement in the methodology applied until now to the characterization of MPs. The ability to characterize and sort MP subpopulations may help to resolve their contributions to normal and pathological functions. © 2007 International Society for Analytical Cytology
Toward a better understanding of depression and anxiety: the involvement of stress and tryptophan hydroxylase activation
Authors: Gittos Maurice W. 
Published: January 2007

AbstractTryptophan hydroxylase (TPH) has been implicated as the key enzyme involved in the etiology of the affective disorders, anxiety and depression. In addition to its activation by stress, TPH is also activated by the amino‐acid decarboxylase inhibitor, NSD 1015, which is widely used for the determination of serotonin turnover. The blockade of this activation by the established antidepressants provides a new, distinct concept to account for the beneficial activity of these compounds. The blockade of the stress‐induced activation of TPH by the benzodiazepine, diazepam, is consistent with its anxiolytic activity involving TPH activation inhibition. In support of the concept, a selective TPH activation inhibitor, AGN 2979, has been reported to exert both powerful antidepressant and anxiolytic effects in the clinic, with a notable lack of the side effects associated with transmitter reuptake inhibition and benzodiazepine receptor interactions.

A high throughput screening approach to identify isocitrate lyase inhibitors from traditional Chinese medicine sources
Authors: Bai Bing , Xie Jian‐Ping , Yan Ju‐Fang , Wang Hong‐Hai , Hu Chang‐Hua 
Published: January 2007

AbstractIsocitrate lyase (ICL) catalyses the first step of the glyoxylate bypass pathway, which reversibly cleaves isocitrate into succinate and glyoxylate. This pathway occurs in a wide range of pathogens and plays a key role in the pathogenesis of Mycobacterium tuberculosis (MTB) suggesting that it may represent a drug target for the treatment of tuberculosis. ICL was cloned, expressed, and purified, and a high‐throughput screen (HTS) developed to screen active extracts derived from traditional Chinese medicines (TCMs) for inhibition of ICL. A colorimetric assay based on the formation of glyoxylate‐phenylhydrazone was used to measure ICL activity. The assay had signal to noise (S/N) of 12.74 and Z′ factor of 0.72, indicating that the assay was suitable for HTS. Screening of a collection of 465 extracts derived from TCMs resulted in the identification of two extracts from Illicium verum Hook.f (Illiciaceae, XHD‐1) and Zingiber officinale Rosc (Zingiberaceae, XHD‐2), which inhibited ICL with IC50 values of 47.7 ± 16.9 and 18.2 ± 0.9 µg/ml, respectively.

Allergy reactions to insulin: effects of continuous subcutaneous insulin infusion and insulin analogues
Authors: Radermecker R. P. , Scheen A. J. 
Published: January 2007

AbstractThe purification of animal insulin preparations and the use of human recombinant insulin have markedly reduced the incidence but not completely suppressed the occurrence of insulin allergy manifestations. Advances in technologies concerning the mode of delivery of insulin, i.e. continuous subcutaneous insulin infusion (CSII), and the use of insulin analogues, resulting from the alteration in the amino acid sequence of the native insulin molecule, may influence the immunogenicity and antigenicity of native insulin. Instead of increasing allergy reactions, CSII has been reported to represent a successful alternative treatment in diabetic patients presenting local or generalized allergy to insulin or other components (zinc, protamine) of conventional treatment. Most recent reports concern CSII‐treated patients using short‐acting insulin analogues (essentially insulin lispro), although the precise role of these insulin analogues remains unclear as allergy to them has also been described. Finally, data on antigenicity and immunogenicity of long‐acting insulin analogues (glargine, detemir), which may mimic the basal insulin delivery with CSII, remain scarce at present.

Complex interference in the eye developmental pathway by Drosophila NF‐YA
Authors: Yoshioka Yasuhide , Suyari Osamu , Yamada Mikihiro , Ohno Katsuhito , Hayashi Yuko , Yamaguchi Masamitsu 
Published: January 2007

AbstractThe CCAAT motif‐binding factor NF‐Y consists of three different subunits, NF‐YA, NF‐YB, and NF‐YC, all of which are required for formation of the NF–Y complex and DNA‐binding. NF‐YA contains a DNA binding domain in its C‐terminal region. We established transgenic fly lines carrying the UAS‐HA‐dNF‐YA or UAS‐dNF‐YAIR and showed over‐expression or knockdown with various GAL4 drivers to be lethal at various developmental stages, suggesting that dNF‐YA participate in various gene regulatory pathways during Drosophila development. Expression of dNF‐YA with eyeless‐GAL4 mainly resulted in lethality with a headless phenotype in pharate‐adults. Reduction of the eyeless gene dose enhanced the dNF‐YA‐induced phenotype, while reduction of the Distal‐less gene dose suppressed the phenotype. On the other hand, crossing the dNF‐YA over‐expressing flies with Notch mutant resulted in no apparent effect on the phenotype. These results suggest that dNF‐YA can disturb eye disc specification, but not eye disc growth. genesis 45:21–31, 2007. © 2007 Wiley‐Liss, Inc.
Knock‐in mice reveal nonsense‐mediated mRNA decay in the brain
Authors: Contet Candice , Dierich Andrée , Kieffer Brigitte L 
Published: January 2007

AbstractNonsense‐mediated mRNA decay (NMD) is a process of mRNA surveillance that degrades transcripts harboring a premature termination codon (PTC). Mammalian NMD was mostly studied in cultured cells so far and there was no direct evidence yet that NMD could operate in the brain. We introduced, by homologous recombination in mouse, a PTC in the mu opioid receptor gene (mor). mor transcript was severely downregulated in the brain of these knock‐in mice. A systemic cycloheximide treatment significantly increased the level of the mutant mRNA, suggesting NMD involvement. To further corroborate this hypothesis, we generated a second knock‐in mouse line where the PTC was placed at 10 instead of 96 nucleotides from the downstream splice junction. As predicted by the “termination codon position rule” established in vitro, mor transcript brain expression was rescued to wild‐type level. These knock‐in mouse lines will be valuable models to better understand and manipulate NMD in vivo. genesis 45:38–43, 2007. © 2007 Wiley‐Liss, Inc.
Human CYP11A1 promoter drives Cre recombinase expression in the brain in addition to adrenals and gonads

Published: January 2007

AbstractThe first step of steroid biosynthesis is catalyzed by cytochrome P450scc, encoded by CYP11A1. To achieve steroidogenic tissue‐specific inactivation of genes in vivo by the Cre‐loxP approach, we used the 4.4‐kb regulatory region of the human CYP11A1 gene to drive Cre recombinase expression in the tissues that produce steroids. The resulting SCC‐Cre mice express high levels of Cre in the adrenal cortex and gonads at the same sites as that for the endogenous CYP11A1 expression. In addition, Cre activity was found in the diencephalon and midbrain. In the developing brain, the Cre activity was first detected in the embryonic day 10.5. Our study is the first to show that the 4.4‐kb CYP11A1 promoter is transcriptionally active in the brain in vivo. genesis 45:59–65, 2007. © 2007 Wiley‐Liss, Inc.

Optical emission spectroscopy of glow discharge plasma from SiH4−CH4 system
Authors: Motohashi Mitsuya , Ashibu Kenta , Hiruta Yasutaka , Homma Kazuaki 
Published: January 2007

AbstractWe used plasma optical emission spectroscopy to investigate the plasma state generated by a radio frequency glow discharge in a monosilane and methane gas mixture. To produce the glow discharge in the gas, we used the source gases separated plasma CVD (SSP‐CVD) method proposed in this research, and the conventional diode method. We studied the flow rate ratio and the radio frequency power dependence of the source gases with the plasma optical emission characteristics generated using these methods, and investigated the relationship between the optical emission states and bond states of the elements in films. We found that the optical emission intensities of SiH and CH radicals in the plasma are related to the carbon content and C‐Si‐H bonds in a‐SiC:H films. Furthermore, we found that more H2 radicals than H radicals exist in plasmas generated by the SSP‐CVD method than in those generated by the conventional method. We used the above results to study the decomposition process of SiH4−CH4 gases. © 2007 Wiley Periodicals, Inc.

Planar‐circuit bandpass filters consisting of arbitrarily shaped elements
Authors: Ohira Masataka , Deguchi Hiroyuki , Tsuji Mikio , Shigesawa Hiroshi 
Published: January 2007

AbstractThis paper presents an arbitrarily shaped circuit as a planar circuit filter optimized by using a genetic algorithm and develops new, never‐before‐seen planar circuit elements. A GA optimization algorithm, which can arbitrarily set the input/output line width and shielding box dimensions according to the optimization conditions for the planar circuit filter, and a method for analyzing planar circuit filters of arbitrarily shaped elements by the method of moments are discussed. As a design example, the authors perform optimizations based on the specifications for a conventional bandpass filter; the resulting filters construct a passband without filter synthesis using an equivalent circuit, and have a smaller size and multiple attenuation poles. The effectiveness of the planar circuit filters with arbitrarily shaped elements is examined by fabricating the filter structures obtained by the GA, performing an experiment, and making a comparison with analytical results. © 2007 Wiley Periodicals, Inc.
