Chemical Imaging of Monolayers on Metal Surfaces: Applications in Corrosion, Catalysis, and Self‐Assembled Monolayers
Authors: Baldelli Steven 
Published: October 2008

AbstractIn situ techniques are indispensable to understanding many topics in surface chemistry. As a consequence, several spectroscopic methods have been developed to provide molecular‐level information that only spectroscopy can supply. However, as important as this information is, it is just as critical to realize that nearly all surfaces under investigation have spatial heterogeneities of the order of nanometers to millimeters; thus, spatial analysis is very important to the overall interpretation. This Minireview focuses on a few of the recent developments in spectroscopic techniques that can provide spatial, spectroscopic, and in situ information. These techniques include photo‐electron microscopy, infrared and Raman imaging, and nonlinear optical imaging vibrational spectroscopy as applied to topics in corrosion, catalysis and self‐assembled monolayers.
Fine‐needle aspiration biopsy of thyroid nodules as a possible source for molecular studies: Analysis of RNA obtained from routine cases
Authors: da Silveira Mitteldorf Cristina Aparecida Troques , de Sousa‐Canavez Juliana Moreira , Massumoto Celso , da Camara‐Lopes Luis Heraldo 
Published: October 2008

AbstractThyroid nodules are frequent in clinical practice and fine‐needle aspiration biopsy (FNAB) is widely used for its evaluation, but approximately 20% of the cases are diagnosed as indeterminate for malignancy. Aspirates from thyroid nodules can be used for ancillary methods, but molecular techniques are not routinely applied to these specimens. Forty‐six consecutive, routinely performed, FNAB of thyroid nodules were evaluated for the feasibility of applying RT‐PCR method. RNA was extracted from 1 of 3 fresh residual samples and analyzed to determine its pureness, integrity, and concentration. Cellularity was adequate in all 46, except one, specimens analyzed, scored as 0, 1+, 2+, 3+, and 4+ in 1, 10, 14, 9, and 8 cases, respectively. Thirty‐three nodules measured less than 1.5 cm. Cytological diagnosis was positive for malignancy in 3 cases, indeterminate for malignancy in 3, most probably benign follicular lesion in 7, negative for malignancy in 32, and suggestive of benign follicular lesion in 1. Good quality RNA was successfully isolated in 45/46 (97.8%) samples, with an average RNA concentration of 14 ng/μl and detection of B2M mRNA in 97.7% (44/45). There was no significant correlation between RNA concentration and nodule size or specimen cellularity. In conclusion, molecular analysis using individual, residual samples of thyroid nodules aspirates is feasible and could be employed for molecular preoperative studies in the future, adding elements for final cytological diagnosis of indeterminate cases, without altering the routine procedure.

Inherited disorders as a risk factor and predictor of neurodevelopmental outcome in pediatric cancer
Authors: Ullrich Nicole J. 
Published: October 2008

AbstractEach year in the United States, an average of one to two children per 10,000 develop cancer. The etiology of most childhood cancer remains largely unknown but is likely attributable to random or induced genetic aberrations in somatic tissue. However, a subset of children develops cancer in the setting of an underlying inheritable condition involving a germline genetic mutation or chromosomal aberration. Despite overall improved survival rates for children with cancer over recent decades, many patients experience neurological and neurocognitive complications during the course of their illness and/or as late effects of treatment. Improvements in therapy, longer survival times, and improved imaging techniques have all increased both the time that patients are at risk and the ability to detect such complications. How an underlying inherited disorder influences the incidence, timing, etiology, and treatment of such sequelae has not been extensively documented, but evidence exists for an increased risk for secondary malignancies and in some cases life‐threatening sensitivity/toxicity to conventionally dosed cancer treatments, thus emphasizing the need for the early recognition of such syndromes. This review outlines the major tumor‐ and treatment‐related neurodevelopmental sequelae in pediatric cancer patients, with particular attention to children with an underlying inheritable disorder. © 2008 Wiley‐Liss, Inc.

Cysteine‐rich secretory proteins are not exclusively expressed in the male reproductive tract
Authors: Reddy Thulasimala , Gibbs Gerard M. , Merriner D. Jo , Kerr Jeffrey B. , O'Bryan Moira K. 
Published: October 2008

AbstractThe Cysteine‐RIch Secretory Proteins (CRISPs) are abundantly produced in the male reproductive tract of mammals and within the venom of reptiles and have been shown to regulate ion channel activity. CRISPs, along with the Antigen‐5 proteins and the Pathogenesis related‐1 (Pr‐1) proteins, form the CAP superfamily of proteins. Analyses of EST expression databases are increasingly suggesting that mammalian CRISPs are expressed more widely than in the reproductive tract. We, therefore, conducted a reverse transcription PCR expression profile and immunohistochemical analyses of 16 mouse tissues to define the sites of production of each of the four murine CRISPs. These data showed that each of the CRISPs have distinct and sometimes overlapping expression profiles, typically associated with the male and female reproductive tract, the secretory epithelia of exocrine glands, and immune tissues including the spleen and thymus. These investigations raise the potential for a role for CRISPs in general mammalian physiology. Developmental Dynamics 237:3313–3323, 2008. © 2008 Wiley‐Liss, Inc.
Frizzled 8a function is required for oligodendrocyte development in the zebrafish spinal cord
Authors: Kim Suhyun , Kim Seok‐Hyung , Kim Ho , Chung Ah‐Young , Cha Yong I. , Kim Cheol‐Hee , Huh Tae‐Lin , Park Hae‐Chul 
Published: October 2008

AbstractOligodendrocytes are the myelinating cells in the central nervous system. The development of oligodendrocytes is mediated by complex signaling networks, including Wnt signaling. Although Wnt signaling has been studied in various aspects of neurogenesis, the distinct roles of various Frizzled receptors that mediate the Wnt signaling in the CNS remain virtually unknown. In order to understand the specific function of Wnt signaling in oligodendrocyte development, we focused on the Frizzled 8a (Fz8a) receptor. Here we show that Fz8a plays a critical role in the specification and maturation of oligodendrocyte progenitor cells (OPCs) in the ventral spinal cord. Loss of Fz8a function perturbed the proliferation and organization of radial glial cells that give rise to OPCs in the ventral precursor region of spinal cord. In addition, we demonstrate that Wnt signaling activation after the specification of OPCs blocks the formation of mature oligodendrocytes and results in the elimination of OPCs.

Lateral fast muscle fibers originate from the posterior lip of the teleost dermomyotome
Authors: Steinbacher P. , Stadlmayr V. , Marschallinger J. , Sänger A.M. , Stoiber W. 
Published: October 2008

AbstractThe predominant source of myogenic cells in vertebrates is the dermomyotome (DM). In teleost fish, recent research has provided a useful but limited picture of how myogenic precursors originate from the DM and how they develop into muscle fibers. Here, we combine detailed morphological analysis with examination of molecular markers in trout to describe the cellular mechanisms by which the lateral fast muscle growth zone is created during second phase myogenesis. Results suggest that this occurs by lateral‐to‐medial immigration of myogenic cells de‐epithelializing from the posterior DM lip. These cells then appear to stop proliferation and migrate anteriorly to finally differentiate into muscle fibres. This seems to be a continuation of the rotational cell movement that creates the teleost DM during early somite development. These findings suggest an evolutionary conserved role of the posterior DM lip in amniotes and fish. Developmental Dynamics 237:3233–3239, 2008. © 2008 Wiley‐Liss, Inc.
Definitive erythropoiesis in chicken yolk sac
Authors: Nagai Hiroki , Sheng Guojun 
Published: October 2008

AbstractThe first wave of erythropoiesis in amniotic animals generates all primitive erythrocytes and takes place exclusively in yolk sac mesoderm. It is less clear, however, to what extent and for how long the yolk sac contributes to the second wave of erythropoiesis which gives rise to definitive erythrocytes for later embryonic and adult use. Here, we examine the initiation, duration, and site of definitive erythrocyte formation in chicken yolk sac. We show that the earliest definitive erythrocytes are generated in yolk sac venous vessels surrounding major arteries at embryonic day (E) 4–4.5, and that mature definitive erythrocytes enter circulating at E4.5–E5. This takes place at a time when yolk sac vasculature remodels extensively to generate paired arterial/venous vessels. The yolk sac remains the predominant site for definitive erythropoiesis from E5 to E10, and continues to generate definitive erythrocytes at least until E15. Similar to primitive erythropoiesis, definitive erythropoiesis in the yolk sac is accompanied by the expression of transcriptional regulators gata1, scl, and lmo2. Furthermore, our data suggest that one main source of definitive erythropoietic cells is the pre‐existing vascular endothelial cells. It remains unclear whether yolk sac derived hematopoietic progenitors that do not undergo erythropoiesis in the yolk sac may take up intraembryonic niches and contribute to erythropoietic stem cell population after hatching.

Error compensation of a position measuring system with moving landmarks for a microrobot
Authors: Torii Akihiro , Inoue Toru , Doki Kae , Ueda Akiteru 
Published: October 2008

AbstractThe error in a position measurement system for a microrobot is described. The system consists of position‐sensitive detectors and moving landmarks, which are lasers mounted on linear stages. The system requires accurate positioning of the linear stages. The position measurement accuracy was investigated by varying the angle formed by the linear stages. Under our experimental conditions, the maximum measurement error was about 0.2 mm, which was reduced to 5µm by using the method of least squares. © 2008 Wiley Periodicals, Inc.

Shapes of nonmonotonic activation functions in a chaotic neural network associative memory model and its evaluation
Authors: Obayashi Masanao , Omiya Rie , Kuremoto Takashi , Kobayashi Kunikazu 
Published: October 2008

AbstractThe purpose of this paper is to investigate the performance of the associative memory model using Aihara's chaotic neural network with different activation functions. Sigmoid function, a monotonic function, was used in Aihara's original model. However, in the static associative memory, it is reported that the storage capacity of the network is improved when a nonmonotonic function is used as the activation function. To improve the associative ability of chaotic neural network, kinds of nonmonotonic functions have been proposed to serve as activation function. This paper investigates their difference as to retrieval ability, and proposes an advanced nonmonotonic function. By computer simulation, we discuss what kind of shape is good regarding improving the associative ability of chaotic neural network. © 2008 Wiley Periodicals, Inc.

Published: October 2008

AbstractA new discrete hexanuclear, mixed‐valence Mn oxide cluster, [Mn6O2(O2CEt)10(H2O)4] (1), has been prepared and used as the building unit for the self‐assembly of a rare propionato‐bridged zigzag‐like chain polymer, [Mn6O2(O2CEt)10(H2O)4]n (2), with the retention of the Mn6 core of 1. Both complexes are characterized by single‐crystal X‐ray structure determinations and magnetic measurements. The discrete complex 1·3H2O crystallizes in orthorhombic space group Pnna with a = 14.2089(6), b = 21.4910(11), and c = 16.4247(6) Å, whereas the polymeric complex 2·2nEtCO2H crystallizes in orthorhombic space group Pbca with a = 13.651(4), b = 25.827(8), and c = 30.312(10) Å. Variable‐temperature magnetic susceptibility analyses show the presence of moderately strong antiferromagnetic interactions within the Mn6 cluster unit in both complexes.(© Wiley‐VCH Verlag GmbH & Co.

N‐glycan analysis by CGE–LIF: Profiling influenza A virus hemagglutinin N‐glycosylation during vaccine production
Authors: Schwarzer Jana , Rapp Erdmann , Reichl Udo 
Published: October 2008

AbstractGlycoproteins, such as monoclonal antibodies as well as recombinant and viral proteins produced in mammalian cell culture play an important role in manufacturing of many biopharmaceuticals. To ensure consisting quality of the corresponding products, glycosylation profiles have to be tightly controlled, as glycosylation affects important properties of the corresponding proteins, including bioactivity and antigenicity. This study describes the establishment of a method for analyzing N‐glycosylation patterns of mammalian cell culture‐derived influenza A virus glycoproteins used in vaccine manufacturing. It comprises virus purification directly from cell culture supernatant, protein isolation, deglycosylation, and clean‐up steps as well as “fingerprint” analysis of N‐glycan pools by CGE‐LIF, using a capillary DNA‐sequencer. Reproducibility studies of CGE‐LIF, virus purification, and sample preparation have been performed. For demonstrating its applicability, the method was exemplarily used for monitoring batch‐to‐batch reproducibility in vaccine production, with respect to the glycosylation pattern of the membrane protein hemagglutinin of influenza A/PR/8/34 (H1N1) virus. This method allows characterization of variations in protein glycosylation patterns, directly by N‐glycan “fingerprint” alignment.
Synthesis of n‐butyl acetamide over immobilized lipase
Authors: Yadav Ganapati D. , Borkar Indrakant V. 
Published: October 2008

AbstractBACKGROUND: The conversion of carboxylic esters to amides can be accomplished efficiently by enzymatic catalysis. Amidation of benzyl acetate with n‐butyl amine was studied in non‐aqueous media using immobilized lipases.RESULTS: The activities of immobilized lipases, Novozym 435, Lipozyme RM IM and Lipozyme TL IM were evaluated in the synthesis of n‐butyl acetamide, among which Novozym 435 was the best. The process was optimized by studying various process parameters. Benzyl acetate conversion of 46% was achieved in 8 h for a mole ratio of 3:1 of n‐butyl amine to benzyl acetate with 3.67 g L−1 Novozym 435 in toluene at 55 °C. A model based on an ordered bi–bi mechanism fitted the initial rate data very well and the rate constant and inhibition constants were calculated by non‐linear regression analysis. The initial rate studies showed that the Michaelis constant for benzyl acetate was low indicating high affinity between the enzyme and the reactant.CONCLUSION: A novel, efficient and environmentally benign enzymatic process is reported for the synthesis of n‐butyl acetamide. This method is general and can be used to synthesize analogous compounds in optically enriched form, since it is difficult to make such amides directly from carboxylic acids and amines by purely chemical means. The theoretical predictions and experimental data matched very well. Copyright © 2008 Society of Chemical Industry
Iliotibial band tension reduces patellar lateral stability
Authors: Merican Azhar M. , Iranpour Farhad , Amis Andrew A. 
Published: October 2008

AbstractThis study investigated the effect of loading the iliotibial band (ITB) on the stability of the patellofemoral joint. We measured the restraining force required to displace the patella 10 mm medially and laterally (defined as medial and lateral stability, respectively) in 14 fresh‐frozen knees from 0 to 90° knee flexion. The testing rig allowed the patella to rotate and translate freely during this displacement. The quadriceps was separated into five components and loaded with 175 N total tension. Testing was performed at 0 to 90 N ITB tension. With no ITB tension, the lateral restraining force ranged from 82 to 101 N across 0 to 90° flexion. Increasing ITB tension caused progressive reduction of the lateral restraining force. The maximum reduction was 25% at 60° flexion and 90 N ITB tension. Medial restraining force increased progressively with increasing knee flexion and increasing ITB loads; it ranged from 74 N at 0° knee flexion and 0 N ITB tension to 211 N at 90° knee flexion and 90 N ITB tension. The maximum effect was an increase of medial restraining force of 50% at 90° flexion and 90 N ITB tension. © 2008 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.
