Seldi-tof MS Profiling of Plasma Proteins in Ovarian Cancer (2006)

This study clearly demonstrates that the combined technology of SELDI-TOF MS and artificial intelligence is effective in distinguishing protein expression between normal and ovarian cancer plasma. The identified protein peaks may be candidate proteins for early detection of ovarian cancer or evaluation of therapeutic response.
Insomnia and Hypersomnia Associated with Depressive Phenomenology and Comorbidity in Childhood Depression (2007)

Clinical profiles differ between depressed children without and with sleep disturbance, with those presenting insomnia plus hypersomnia being most severely depressed. Differentiating depressed children with different sleep disturbances may have important implications for research efforts on the etiology and therapeutics of child depression.

Recent progress in the assays of xylanolytic enzymes (2006)

Abstract Increasing industrial importance of xylanolytic enzymes together with recent evidence for cereal endoxylanase inhibitors having a negative impact on the application of enzymes in fodder and food industries, brings challenges to facilitate and simplify the procedures to follow these enzymes. This article gives a critical evaluation of current methods and outlines new methodological alternatives to follow the major depolymerising enzyme, endo‐β‐1,4‐xylanase using chromogenic substrates. Attention is paid also to assays of three accessory xylanolytic enzymes α‐glucuronidase, acetylxylan esterase and feruloyl esterase, for which new enzyme‐coupled assays were elaborated.

The Neuropsychopharmacology of Fronto-Executive Function: Monoaminergic Modulation (2009)

We review the modulatory effects of the catecholamine neurotransmitters noradrenaline and dopamine on prefrontal cortical function. The effects of pharmacologic manipulations of these systems, sometimes in comparison with the indoleamine serotonin (5-HT), on performance on a variety of tasks that tap working memory, attentional-set formation and shifting, reversal learning, and response inhibition are compared in rodents, nonhuman primates, and humans using, in a behavioral context, several techniques ranging from microiontophoresis and single-cell electrophysiological recording to pharmacologic functional magnetic resonance imaging. Dissociable effects of drugs and neurotoxins affecting these monoamine systems suggest new ways of conceptualizing state-dependent fronto-executive functions, with implications for understanding the molecular genetic basis of mental illness and its treatment.
Characterization of a cDNA clone coding for the beta chain of bovine fibrinogen. (1981)

Recombinant plasmids containing bovine cDNA have been screened with a radiolabeled cDNA enriched for bovine fibrinogen. A number of plasmids containing cDNAs for fibrinogen were identified by this assay. One plasmid, designated pBI beta 1, was found to contain a cDNA insert of 1372 base pairs. The sequence of the cDNA insert for this plasmid was then determined. It was shown to code for 424 amino acids of the beta chain of fibrinogen, starting with residue 44. This and other data made it possible to construct the complete amino acid sequence of the beta chain of the protein. Comparison of the amino acid sequence of the beta chain of bovine fibrinogen with the corresponding chain of the human molecule indicated that the two chains are greater than 80% homologous.
Inhibitory Effect of a Protease Inhibitor, Leupeptin, on the Development of Influenza Pneumonia, Mediated by Concomitant Bacteria (1987)

The protease inhibitor leupeptin prevented multiple step replication of an influenza virus (A/swine/1976/31, H1N1) mediated by staphylococcal proteases. It also suppressed virus replication and development of fatal pneumonia in mice co-infected with the virus and Staphylococcus aureus.
Panallergens and their impact on the allergic patient (2010)

The panallergen concept encompasses families of related proteins, which are involved in general vital processes and thus, widely distributed throughout nature. Plant panallergens share highly conserved sequence regions, structure, and function. They are responsible for many IgE cross-reactions even between unrelated pollen and plant food allergen sources. Although usually considered as minor allergens, sensitization to panallergens might be problematic as it bears the risk of developing multiple sensitizations. Clinical manifestations seem to be tightly connected with geographical and exposure factors. Future population- and disease-based screenings should provide new insights on panallergens and their contribution to disease manifestations. Such information requires molecule-based diagnostics and will be valuable for developing patient-tailored prophylactic and therapeutic approaches. In this article, we focus on profilins, non-specific lipid transfer proteins, polcalcins, and Bet v 1-related proteins and discuss possible consequences of panallergen sensitization for the allergic patient. Based on their pattern of IgE cross-reactivity, which is reflected by their distribution in the plant kingdom, we propose a novel classification of panallergens into ubiquitously spread "real panallergens" (e.g. profilins) and widespread "eurallergens" (e.g. polcalcins). "Stenallergens" display more limited distribution and cross-reactivity patterns, and "monallergens" are restricted to a single allergen source.
Indium contamination from the indium–tin–oxide electrode in polymer light-emitting diodes (1996)

We have found that polymer light-emitting diodes (LEDs) contain high concentrations of metal impurities prior to operation. Narrow peaks in the electroluminescence spectrum unambiguously demonstrate the presence of atomic indium and aluminum. Rutherford backscattering spectroscopy (RBS) and x-ray photoelectron spectroscopy (XPS) depth profiling data corroborate this result. An average indium concentration of 5×1019atoms/cm3 originating from the indium–tin–oxide (ITO) electrode has been found in the polymer layer.
Membrane Ig cross-linking regulates phosphatidylinositol 3-kinase in B lymphocytes (1992)

Cross-linking of the B cell AgR results in activation of mature B cells and tolerization of immature B cells. The initial signaling events stimulated by membrane immunoglobulin (mIg) cross-linking are tyrosine phosphorylation of a number of proteins. Among the targets of mIg-induced tyrosine phosphorylation are the tyrosine kinases encoded by the lyn, blk, fyn, and syk genes, the mIg-associated proteins MB-1 and Ig-beta, phospholipase C-gamma 1 and -gamma 2, as well as many unidentified proteins. In this report we show that mIg cross-linking also regulates phosphatidylinositol 3-kinase (PtdIns 3-kinase), an enzyme that phosphorylates inositol phospholipids and plays a key role in mediating the effects of tyrosine kinases on growth control in fibroblasts. Cross-linking mIg on B lymphocytes greatly increased the amount of PtdIns 3-kinase activity which could be immunoprecipitated with anti-phosphotyrosine (anti-tyr(P) antibodies. This response was observed after mIg cross-linking in mIgM- and mIgG-bearing B cell lines and after cross-linking either mIgM or mIgD in murine splenic B cells. Thus, regulation of PtdIns 3-kinase is a common feature of signaling by several different isotypes of mIg. This response was rapid and peaked 2 to 3 min after the addition of anti-Ig antibodies. The anti-Ig-stimulated increase in PtdIns 3-kinase activity associated with anti-Tyr(P) immunoprecipitates could reflect increased tyrosine phosphorylation of PtdIns 3-kinase, increased activity of the enzyme, or both. In favor of the first possibility, the tyrosine kinase inhibitor herbimycin A blocked the increase in ant-Tyr(P)-immunoprecipitated PtdIns 3-kinase activity as well as the anti-Ig-induced tyrosine phosphorylation. Moreover, this response was not secondary to phospholipase C activation but rather seemed to be a direct consequence of mIg-induced tyrosine phosphorylation. Activation of the phosphoinositide pathway by a transfected M1 muscarinic acetylcholine receptor expressed in WEHI-231 B lymphoma cells did not increase the amount of PtdIns 3-kinase activity which could be precipitated with anti-Tyr(P) antibodies. Similarly, inhibition of the phosphoinositide pathway did not abrogate the ability of mIg cross-linking to stimulate this response. Thus, mIg-induced tyrosine phosphorylation regulates PtdIns 3-kinase, an important mediator of growth control in fibroblasts and potentially an important regulatory component in B cells as well.

Automated commercial synthesis system for preparation of O‐(2‐[18F]fluoroethyl)‐L‐tyrosine by direct nucleophilic displacement on a resin column (2003)

Abstract A slightly modified automated commercial synthesis system for preparation of O ‐(2‐[ 18 F]fluoroethyl)‐l‐tyrosine (FET), an amino acid tracer for tumor imaging with positron emission tomography, is described. Direct nucleophilic fluorination of [ 18 F]fluoride with 1,2‐di(4‐methylphenylsulfonyloxy)ethane on a quaternary 4‐(4‐methylpiperidinyl)‐pyridinium functionalized polystyrene anion exchange resin gave 1‐[ 18 F]‐2‐(4‐methylphenylsulfonyloxy)ethane, then [ 18 F]fluoroalkylation of l‐tyrosine yielded FET. The overall radiochemical yield with no decay correction was about 8–10%, the whole synthesis time was about 52 min, and the radiochemical purity was above 95%.

Respiratory epithelium inhibits bronchial smooth muscle tone (1985)

The aim of the present study was to determine whether or not the respiratory epithelium can modulate the responsiveness of bronchial smooth muscle. Paired rings of canine bronchi (4-6 mm OD), in some of which the epithelium had been removed mechanically (by rubbing the luminal surface), were mounted in physiological saline solution, gassed with 95% O2-5% CO2, and maintained at 37 degrees C. The presence or absence of the epithelium was confirmed by histological examination. Removal of the epithelium increased the contractile responses evoked by acetylcholine, histamine, and 5-hydroxytryptamine. Transmural nerve stimulation evoked similar peak responses in the presence and absence of epithelium. In unrubbed preparations, the peak response was followed by a gradual decrease when the stimulation was continued. This decrease, which persisted in the presence of propranolol, was not observed in epithelium-denuded preparations. In bronchial rings contracted with acetylcholine, isoproterenol produced concentration-dependent relaxations which were significantly greater in rings with epithelium compared with denuded rings. These results suggest that respiratory epithelial cells may generate an inhibitory signal to decrease the responsiveness of bronchial smooth muscle to contractile agonists and augment the effectiveness of inhibitory stimuli.
Geometry of the Vapor Layer Under a Leidenfrost Drop (2012)

In the Leidenfrost effect, liquid drops deposited on a hot surface levitate on a thin vapor cushion fed by evaporation of the liquid. This vapor layer forms a concave depression in the drop interface. Using laser-light interference coupled to high-speed imaging, we measured the radius, curvature, and height of the vapor pocket, as well as nonaxisymmetric fluctuations of the interface for water drops at different temperatures. The geometry of the vapor pocket depends primarily on the drop size and not on the substrate temperature.
PARP16 is a tail-anchored endoplasmic reticulum protein required for the PERK and IRE1Î±-mediated unfolded protein response (2012)

Poly(ADP-ribose) polymerases (PARPs) (also known as ADP-ribosyl transferase D proteins) modify acceptor proteins with ADP-ribose modifications of varying length (reviewed in refs\n1â3). PARPs regulate key stress response pathways, including DNA damage repair and the cytoplasmic stress response2,3,4,5,6. Here, we show that PARPs also regulate the unfolded protein response (UPR) of the endoplasmic reticulum (ER). Human PARP16/ARTD15 is a tail-anchored ER transmembrane protein required for activation of the functionally related ER stress sensors PERK and IRE1Î± during the UPR. The third identified ER stress sensor, ATF6, is not regulated by PARP16. Similar to other PARPs that function during stress, PARP16 enzymatic activity is up-regulated during ER stress when it (ADP-ribosyl)ates itself, PERK and IRE1Î±. (ADP-ribosyl)ation by PARP16 is sufficient for activating PERK and IRE1Î± in the absence of ER stress, and is required for PERK and IRE1 Î± activation during the UPR. Modification of PERK and IRE1Î± by PARP16 increases their kinase activities and the endonuclease activity of IRE1Î±. Interestingly, the C-terminal luminal tail of PARP16 is required for PARP16 function during ER stress, suggesting that it transduces stress signals to the cytoplasmic PARP catalytic domain.
Mutational analysis of cis elements involved in E2 modulation of human papillomavirus type 16 P97 and type 18 P105 promoters (1990)

cis-Acting elements involved in E2 modulation of human papillomavirus type 16 (HPV-16) P97 promoter activity and HPV-18 P105 promoter activity were examined. In transfected primary human keratinocytes, each promoter had a basal activity that could be repressed by the bovine papillomavirus type 1 E2 gene product. Mutational analysis of the E2-binding sites in the long control region upstream of each promoter revealed that E2 repression was mediated through the E2-binding sites proximal to each promoter. In the context of a mutated E2-binding site at the promoter proximal position, the HPV-16 P97 and HPV-18 P105 promoters could be transactivated by E2. E2-mediated repression of HPV-18 P105 promoter activity was shown to be a transcriptional effect. The interaction of E2 with promoter-proximal E2-binding sites is likely to be important for the controlled expression of viral genes transcribed from the HPV-16 P97 promoter and the HPV-18 P105 promoter in infected human genital epithelial cells.

A multimodal virtual reality interface for 3D interaction with VTK (2007)

The object-oriented visualization Toolkit (VTK) is widely used for scientific visualization. VTK is a visualization library that provides a large number of functions for presenting three-dimensional data. Interaction with the visualized data is controlled with two-dimensional input devices, such as mouse and keyboard. Support for real three-dimensional and multimodal input is non-existent. This paper describes VR-VTK: a multimodal interface to VTK on a virtual environment. Six degree of freedom input devices are used for spatial 3D interaction. They control the 3D widgets that are used to interact with the visualized data. Head tracking is used for camera control. Pedals are used for clutching. Speech input is used for application commands and system control. To address several problems specific for spatial 3D interaction, a number of additional features, such as more complex interaction methods and enhanced depth perception, are discussed. Furthermore, the need for multimodal input to support interaction with the visualization is shown. Two existing VTK applications are ported using VR-VTK to run in a desktop virtual reality system. Informal user experiences are presented.
Perovskite ferroelectric nanomaterials (2013)

In this review, the main concept of ferroelectricity of perovskite oxides and related materials at nanometer scale and existing difficulties in the synthesis of those nanocrystals are discussed. Important effects, such as depolarization field and size effect, on the existence of ferroelectricity in perovskite nanocrystals are deliberated. In the discussion of modeling works, different theoretical calculations are pinpointed focusing on their studies of lattice dynamics, phase transitions, new origin of ferroelectricity in nanostructures, etc. As the major part of this review, recent research progress in the facile synthesis, characterization and various applications of perovskite ferroelectric nanomaterials, such as BaTiO₃, PbTiO₃, PbZrO₃, and BiFeO₃, are also scrutinized. Perspectives concerning the future direction of ferroelectric nanomaterials research and its potential applications in renewable energy, etc., are presented. This review provides an overview in this area and guidance for further studies in perovskite ferroelectric nanomaterials and their applications.
trans-Complementation of yellow fever virus NS1 reveals a role in early RNA replication (1997)

Mutational analysis of the nonstructural protein 1 (NS1) of yellow fever virus (YF) has implicated it in viral RNA replication. To further explore this observation, we sought a method for uncoupling NS1 function from NS1 expression and processing as part of the large YF polyprotein. Here we describe a strategy for providing NS1 in trans, utilizing a noncytopathic Sindbis virus vector. Replication of a defective YF genome containing a large in-frame deletion of NS1 was dependent on functional expression of NS1. Recovered mutant virus was shown to contain the deletion and was neutralized by YF-specific antiserum. Complemented mutant virus increased in titer with kinetics similar to those of parental YF 17D but peaked at lower titers. trans-complementation has allowed us to derive high-titer, helper-free stocks of YF defective in NS1 with which to further characterize the role of this gene product in RNA replication. The first cycles of RNA replication were analyzed by using a sensitive strand-specific RNase protection assay. We document these events for mutant and wild-type viruses in the presence or absence of complementation. These data strongly suggest a role for NS1 prior to or at initial minus-strand synthesis.
The Role of HDAC6 in Cancer (2010)

Histone deacetylase 6 (HDAC6), a member of the HDAC family whose major substrate is α-tubulin, has become a target for drug development to treat cancer due to its major contribution in oncogenic cell transformation. Overexpression of HDAC6 correlates with tumorigenesis and improved survival; therefore, HDAC6 may be used as a marker for prognosis. Previous work demonstrated that in multiple myeloma cells, inhibition of HDAC6 results in apoptosis. Furthermore, HDAC6 is required for the activation of heat-shock factor 1 (HSF1), an activator of heat-shock protein encoding genes (HSPs) and CYLD, a cylindromatosis tumor suppressor gene. HDAC6 contributes to cancer metastasis since its upregulation increases cell motility in breast cancer MCF-7 cells and its interaction with cortactin regulates motility. HDAC6 also affects transcription and translation by regulating the heat-shock protein 90 (Hsp90) and stress granules (SGs), respectively. This review will discuss the role of HDAC6 in the pathogenesis and treatment of cancer.
BRAF mutation in thyroid cancer (2005)

Genetic alteration is the driving force for thyroid tumorigenesis and progression, based upon which novel approaches to the management of thyroid cancer can be developed. A recent important genetic finding in thyroid cancer is the oncogenic T1799A transversion mutation of BRAF (the gene for the B-type Raf kinase, BRAF). Since the initial report of this mutation in thyroid cancer 2 years ago, rapid advancements have been made. BRAF mutation is the most common genetic alteration in thyroid cancer, occurring in about 45% of sporadic papillary thyroid cancers (PTCs), particularly in the relatively aggressive subtypes, such as the tall-cell PTC. This mutation is mutually exclusive with other common genetic alterations, supporting its independent oncogenic role, as demonstrated by transgenic mouse studies that showed BRAF mutation-initiated development of PTC and its transition to anaplastic thyroid cancer. BRAF mutation is mutually exclusive with RET/PTC rearrangement, and also displays a reciprocal age association with this common genetic alteration in thyroid cancer. The T1799A BRAF mutation occurs exclusively in PTC and PTC-derived anaplastic thyroid cancer and is a specific diagnostic marker for this cancer when identified in cytological and histological specimens. This mutation is associated with a poorer clinicopathological outcome and is a novel independent molecular prognostic marker in the risk evaluation of thyroid cancer. Moreover, preclinical and clinical evaluations of the therapeutic value of novel specific mitogen-activated protein kinase pathway inhibitors in thyroid cancer are anticipated. This newly discovered BRAF mutation may prove to have an important impact on thyroid cancer in the clinic.
Heteroepitaxial growth of SrO films on Si substrates (1987)

Epitaxial growth of SrO thin films onto Si(111) and (100) substrates by means of molecular-beam epitaxy has been demonstrated. The orientation relationships between epitaxial SrO and Si were found to be (111)SrO//(111)Si and [112̄]SrO//[112̄]Si, (100)SrO//(100)Si and [011]SrO//[001]Si. The composition of the grown films was Sr:O=1:1. In addition, it has been shown that it was possible to grow layers with no Si surface oxidation and no noticeable interdiffusion at the interfaces. These SrO films possess a low dielectric constant (3.0) and a high breakdown field (5×106 V/cm).
CD45‐assisted PanLeucogating for accurate, cost‐effective dual‐platform CD4+ T‐cell enumeration (2002)

These observations show that DP leucocyte counts (WCC) should replace lymphocyte counts as the "common denominator" although CD4%/lympho values can, as an extra step, be also provided readily if requested. When coupled with quality control for WCC on hematology analyzers, the DP method with CD45 PanLeucogating represents a robust CD4 T-cell assay that is as accurate as the SP volumetric technique. This DP method uses only two, CD45 and CD4, antibody reagents and can be run on any pair of hematological analyzer plus flow cytometer.
