Fyn
Authors: Saito Yoshihito D. , Jensen Ana R. , Salgia Ravi , Posadas Edwin M. 
Published: February 2010

AbstractFyn is 59‐kDa member of the Src family of kinases that is historically associated with T‐cell and neuronal signaling in development and normal cellular physiology. Whereas Src has been heavily studied in cancer, less attention has been traditionally awarded to the other Src kinases such as Fyn. Our group has shown that Fyn is particularly upregulated in prostate cancer in contrast to the alternative members of the Src family. This suggests that it may mediate several important processes attributed to Src kinases in prostate cancer and other malignancies. These functions include not only cellular growth and proliferation but also morphogenesis and cellular motility. Together, these suggest a role for Fyn in both progression and metastasis. As several agents in clinical development affect Fyn activation, understanding the role that Fyn plays in cancer is of great importance in oncology. Cancer 2010. © 2010 American Cancer Society.
Commentary on effects of radiotherapy with concomitant and adjuvant temozolomide versus radiotherapy alone on survival in glioblastoma in a randomised phase III study: 5‐Year analysis of the EORTC‐NCIC trial (Lancet Oncol. 2009;10:459‐466)
Authors: Linz Ute 
Published: February 2010

AbstractRecently, un update of the important European Organization for Research and Treatment of Cancer study 26981 was published without correcting deficiencies that already were known and publicized in 2008. In the current commentary, the author specifies those issues to help prevent incorrect conclusions and discusses reasons why the journal that published the update dismissed a letter clarifying those shortcomings.

Accuracy and sensitivity of computed tomography‐guided percutaneous needle biopsy of pulmonary hilar lymph nodes
Authors: Avritscher Rony , Krishnamurthy Savitri , Ensor Joe , Gupta Sanjay , Tam Alda , Madoff David C. , Murthy Ravi , Hicks Marshall E. , Wallace Michael J. 
Published: February 2010

AbstractBACKGROUND:Because of their proximity to the pulmonary artery or vein, hilar lymph nodes are routinely biopsied with endobronchial or endoscopic ultrasonography (EUS)‐guided fine‐needle aspiration biopsy (FNAB). Computed tomography (CT)‐guided percutaneous needle biopsy (PNB) allows the operator to acquire a larger core needle biopsy (CNB) when initial samples are inconclusive, when the suspected disease is not optimally diagnosed with FNAB, or when biomarkers are required. The purpose of this study was to retrospectively evaluate the sensitivity and accuracy of CT‐guided PNB in patients with hilar adenopathy.METHODS:The authors identified 80 patients who underwent 81 CT‐guided PNBs of pulmonary hilar lesions from October 2002 through December 2006 and retrospectively reviewed their medical and imaging records. The PNB sensitivity and accuracy were calculated in each case, and each case was reviewed for complications, including pneumothorax and subsequent thoracostomy tube insertion.RESULTS:PNB included FNAB and CNB in 81 (100%) and 14 (17%) procedures, respectively. Data on 69 PNB specimens (67 FNAB specimens and 13 CNB specimens) were available for statistical analysis. Overall, PNB had a sensitivity of 91.4% (95% confidence interval [CI], 81.0%‐97.1%) and an accuracy rate of 92.8% (95% CI, 83.9%‐97.1%). Pneumothoraxes occurred in 39 patients (48%), 26 (32%) of whom required thoracostomy tube insertion.CONCLUSIONS:CT‐guided PNB of pulmonary hilar lesions has high sensitivity and accuracy and represents a viable alternative for endobronchial ultrasound‐ or EUS‐guided FNAB when larger biopsy samples are required for diagnosis or biomarker analysis. However, the procedure can result in high rates of pneumothorax. Cancer 2010. © 2010 American Cancer Society.
The effects of detergents on the polymerization properties of actin
Authors: Ujfalusi‐Pozsonyi Kinga , Hild Gábor , Gróf Pál , Gutay‐Tóth Zsuzsanna , Bacsó Zsolt , Nyitrai Miklós 
Published: February 2010

AbstractEffects of some detergents—most frequently used in membrane raft studies—on the polymerization properties of actin were examined under in vitro and in vivo conditions, for protein and cellular investigations, respectively. Under in vitro conditions the polymerization rates were measured with pyrene‐labeled actin. We found that polymerization rate depended on the detergent concentration by following either biphasic characteristics or only decreasing tendency. The strongest effects were observed at relatively low detergent concentrations. SDS–PAGE electrophoresis and dynamic light‐scattering measurements provided further evidences for the size distribution of actin filaments formed under the influence of detergents. Comparing the polymerization rates measured in the presence of different detergents to those obtained with various magnesium and KCl concentrations showed that detergents may influence the actin polymerization at three levels by modifying: (i) the monomer–monomer interaction, (ii) the local ionic strength, and (iii) the affinity of actin for various cations. In vivo studies on NIH 3T3MDR1 cells using TRITC‐phalloidin detected fast depolymerization of large extent around the critical micellar concentrations of the detergents. We concluded that microdomain insolubility observed in the presence of detergents is hardly to be the result of the stabilization of the submembrane actin cytoskeleton merely; rather inter‐lipid and lipid–protein interactions are also involved within the detergent‐resistant membranes. © 2010 International Society for Advancement of Cytometry
Multichromatic phenotyping of HER receptor coexpression in breast tumor tissue samples using flow cytometry—Possibilities and limitations

AbstractThe prognostic significance of HER2 expression in human breast carcinomas is beyond dispute nowadays. The HER family of receptor tyrosine kinases comprises four members (HER1/ErbB1/EGFR, HER2/ErbB2, HER3/ErbB3, and HER4/ErbB4) that act in concert via transactivation and consequently compose a functional signaling unit. Besides HER2 overexpression, coexpression of other HER receptors has substantial impact on course of disease and potential therapeutic benefit. This observation is substantiated by numerous preclinical studies and retrospective studies done on patients with breast cancer. Against this background, the quantification of all HER receptor expressions at the same time would significantly extend the information content revealed by routine diagnosis of breast cancer tissues. Moreover, the knowledge of HER receptor coexpression profiles in primary tumor samples could provide the basis to design and develop highly specific antireceptor treatment strategies. Here, we report on a simultaneous flow cytometric detection of all four HER receptors on carcinoma cells isolated from primary breast cancer tissues and separated from nonepithelial cells by cytokeratin staining. Combined with DNA, i.e. ploidy quantification, the approach resulted in a six‐parameter assay that could complement the diagnosis of a variety of diseases in which HER receptor expression has a pivotal impact on the degree of malignancy. © 2010 International Society for Advancement of Cytometry
Reaction of a Stable Conjugated Primary Enamine with Piers' Borane (Eur. J. Inorg. Chem. 6/2010)
Authors: Peuser Ilona , Fröhlich Roland , Kehr Gerald , Erker Gerhard 
Published: February 2010

AbstractThe cover picture shows a sketch of the reaction of a rare example of a stable conjugated primary enamine with Piers' borane that initially leads to the formation of the borane‐stabilized imine tautomers, which subsequently rearrange to the hydroboration product whose favoured imine–borane coordinated structure was characterized by X‐ray diffraction. Details are discussed in the article by G. Erker et al. on p. 849 ff.

Published: February 2010

AbstractThis is the first account of a successful, PdII‐catalysed enantioselective addition of phenylboronic acid to electron‐deficient N‐tosylarylimines by using chiral diphosphane ligands. A number of commercial diphosphane ligands were screened. Despite moderate to good yields, ee values of 99 % could be achieved with MeDuPhos. Novel RhI catalysts were also screened, and ee values as high as 74 % could be obtained.
Quantum Mechanical Calculation of NMR Parameters in the Stereostructural Determination of Natural Products
Authors: Di Micco Simone , Chini Maria Giovanna , Riccio Raffaele , Bifulco Giuseppe 
Published: February 2010

AbstractThe present microreview highlights the recent goals reached by the application of a combined approach of NMR spectroscopy and quantum chemical methods in the structural studies of natural products. In particular, different case studies are reported, showing the comparison of calculated NMR parameters at the quantum mechanical (QM) theory level with experimental data for the configurational assignment of organic compounds. Moreover, it is shown that the QM–NMR approach can be used as a fast and convenient method to lead the total synthesis of complex natural products to the correct stereoisomer. Through recent analysis of the covalent complex formed between d(GACTAATTGAC)‐(GTCAATTAGTC) and (+)‐yatakemycin, the potential application of this hybrid method as a useful tool for the characterization of bioactive molecule–biopolymer interactions is presented.
Cannabimovone, a Cannabinoid with a Rearranged Terpenoid Skeleton from Hemp

Published: February 2010

AbstractAn investigation of the polar fractions from a nonpsychotropic variety of hemp (Cannabis sativa L.) afforded cannabimovone (6), a polar cannabinoid with a rearranged 2(3→4) abeo‐terpenoid skeleton, biogenetically originating from the intramolecular aldolization of a 2′,3′‐seco‐menthanyl precursor. The structure of cannabimovone was elucidated by spectroscopic analysis, whereas attempts to mimic its biogenetic derivation from cannabidiol (2) gave only anhydrocannabimovone (12), the intramolecular oxy‐Michael adduct of the crotonized version (11b) of the elusive natural products. Biological evaluation of cannabimovone (6) against metabotropic (CB1, CB2) and ionotropic (TRPs) cannabinoid receptors showed a significant activity only for ionotropic receptors, especially TRPV1, whereas anhydrocannabimovone (12) exhibited strong activity at both ionotropic and metabotropic cannabinoid receptors. Overall, the biological profile of anhydrocannabimovone (12) was somewhat similar to that of THC (4), suggesting a remarkable tolerance to constitutional and configurational changes.
Capacitively coupled contactless conductivity detection with dual top–bottom cell configuration for microchip electrophoresis

Published: February 2010

AbstractAn optimized capacitively coupled contactless conductivity detector for microchip electophoresis is presented. The detector consists of a pair of top–bottom excitation electrodes and a pair of pickup electrodes disposed onto a very thin plastic microfluidic chip. The detection cell formed by the electrodes is completely encased and shielded in a metal housing. These approaches allow for the enhancement of signal coupling and extraction from the detection cell that result in an improved signal‐to‐noise‐ratio and detection sensitivity. The improved detector performance is illustrated by the electrophoretic separation of six cations (NH, K+, Ca2+, Na+, Mg2+, Li+) with a detection limit of approximately 0.3 μM and the analysis of the anions (Br−, Cl−, NO, NO, SO, F−) with a detection limit of about 0.15 μM. These LODs are significantly improved compared with previous reports using the conventional top–top electrode geometry. The developed system was applied to the analysis of ions in bottled drinking water samples.
Thermal instability of a boundary layer subjected to external electric and magnetic fields
Authors: Chen Chin‐Tai 
Published: February 2010

AbstractThis paper presents a numerical study of the electrical and magnetic fields on thermal instability in a boundary layer. The criterion on the position marking on the onset of longitudinal vortices is defined in the present paper. The results show that the onset position characterized by the Grashof number depends on the Prandtl number, the Reynolds number, the wave number, the electric field parameter, and the Hartmann number. The flow becomes more stable as the magnetic field increases. However, the destabilizing effect is found on the flow when the negative electric field parameter is applied. The results of the present numerical prediction show reasonable agreement with the experimental data in the case of zero Hartmann number and zero electric field parameter in the literature.
