Cloning and expression of murine enzymes involved in the salvage pathway of GDP‐<scp>l</scp>‐fucose (2003)

In the salvage pathway of GDP-L-fucose, free cytosolic fucose is phosphorylated by L-fucokinase to form L-fucose-L-phosphate, which is then further converted to GDP-L-fucose in the reaction catalyzed by GDP-L-fucose pyrophosphorylase. We report here the cloning and expression of murine L-fucokinase and GDP-L-fucose pyrophosphorylase. Murine L-fucokinase is expressed as two transcripts of 3057 and 3270 base pairs, encoding proteins of 1019 and 1090 amino acids with predicted molecular masses of 111 kDa and 120 kDa respectively. Only the longer splice variant of L-fucokinase was enzymatically active when expressed in COS-7 cells. Murine GDP-L-fucose pyrophosphorylase has an open reading frame of 1773 base pairs encoding a protein of 591 amino acids with a predicted molecular mass of 65.5 kDa. GDP-L-fucose, the reaction product of GDP-L-pyrophosphorylase, was identified by HPLC and MALDI-TOF MS analysis. The tissue distribution of murine L-fucokinase and GDP-L-fucose pyrophosphorylase was investigated by quantitative real time PCR, which revealed high expression of L-fucokinase and GDP-L-fucose pyrophosphorylase in various tissues. The wide expression of both enzymes can also be observed from the large amount of data collected from a number of expressed sequence tag libraries, which indicate that not only the de novo pathway alone, but also the salvage pathway, could have a significant role in the synthesis of GDP-L-fucose in the cytosol.
Exclusive destruction of mitotic spindles in human cancer cells (2017)

We identified target proteins modified by phenanthrenes that cause exclusive eradication of human cancer cells. The cytotoxic activity of the phenanthrenes in a variety of human cancer cells is attributed by these findings to post translational modifications of NuMA and kinesins HSET/kifC1 and kif18A. Their activity prevented the binding of NuMA to α-tubulin and kinesins in human cancer cells, and caused aberrant spindles. The most efficient cytotoxic activity of the phenanthridine PJ34, caused significantly smaller aberrant spindles with disrupted spindle poles and scattered extra-centrosomes and chromosomes. Concomitantly, PJ34 induced tumor growth arrest of human malignant tumors developed in athymic nude mice, indicating the relevance of its activity for cancer therapy.
Photoresponsive Halogen-Bonded Liquid Crystals: The Role of Aromatic Fluorine Substitution (2019)

A new strategy for controlling the liquid crystalline and photophysical properties of supramolecular mesogens assembled via halogen bonding is reported. Changing the degree of fluorination at the halogen-bond donor of the supramolecular liquid crystal allows for the fine-tuning of the halogen bond strength and thereby provides control over the temperature range of the mesophase. At least three fluorine atoms have to be present to ensure efficient polarization of the halogen-bond donor and the formation of a mesophase. In addition, it was found that stilbazole acceptors are superior to their azopyridine counterparts in promoting stable liquid crystalline phases. The halogen-bond-driven supramolecular liquid crystals between fluorinated azobenzenes and stilbazole/azopyridine acceptors show a rich variety of photoinduced processes driven by azobenzene photoisomerization, dictated not only by the photochemical properties of the molecular components but also by the difference between the operation temperature and the clearing point.
Visual looming and receding networks in awake marmosets investigated with fMRI (2019)

Abstract An object that is looming toward a subject or receding away contains important information for determining if this object is dangerous, beneficial or harmless to them. This information (motion, direction, identity, time-to-collision, size, velocity) is analyzed by the brain in order to execute the appropriate behavioral responses depending on the context: fleeing, freezing, grasping, eating, exploring. In the current study, we performed ultra-high-field functional MRI (fMRI) in awake marmosets to explore the patterns of brain activation elicited by visual stimuli looming toward or receding away from the monkey. We found that looming and receding visual stimuli both activate a large cortical network in frontal, parietal, temporal and occipital cortex in areas involved in the analysis of motion, shape, identity and features of the objects. Looming stimuli strongly activated a network composed of the pulvinar, superior colliculus, prefrontal cortex and temporal cortical areas. This may underlie the existence of an alert network that processes the visual stimuli looming toward their peripersonal space by extracting the crucial information brought by the stimulus and evaluating its potential consequences to the observer. We hypothesize that this network is involved in the planning of protective behaviors (e.g. fleeing or freezing) and in emotional reaction (e.g. anxiety, fear). These findings support the view that this network is preserved through evolution and that the marmoset is a viable model to study visual and multisensory processes by using fMRI to guide further invasive recordings and/or pharmacological manipulations. Significant statement An object that is looming toward a subject or receding away contains important information for determining if this object is dangerous, beneficial or harmless to them. Here, we identified the functional network in non-human primates that was activated by visual stimuli looming toward or away from the animals using ultra-high-field functional magnetic resonance imaging. Our findings show that large cortical activations are elicited by both looming and receding visual conditions. However, some activations were specific to the looming condition, suggesting that the integration of cues in the looming direction rely on strong connections between cortical and subcortical areas, which allows primates to react properly for protecting themselves against a potential threat.
Synthesis, Linear, and Quadratic‐Nonlinear Optical Properties of Octupolar <i>D</i><sub>3</sub> and <i>D</i><sub>2<i>d</i></sub> Bipyridyl Metal Complexes (2004)

A series of D3 (Fe(II), Ru(II), Zn(II), Hg(II)) and D2d (Cu(I), Ag(I), Zn(II)) octupolar metal complexes featuring different functionalized bipyridyl ligands has been synthesized, and their thermal, linear (absorption and emission), and nonlinear optical (NLO) properties were determined. Their quadratic NLO susceptibilities were determined by harmonic light scattering at 1.91 microm, and the molecular hyperpolarizability (beta0) values are in the range of 200-657 x 10(-30) esu for octahedral complexes and 70-157 x 10(-30) esu for tetrahedral complexes. The octahedral zinc(II) complex 1 e, which contains a 4,4'-oligophenylenevinylene-functionalized 2,2'-bipyridine, exhibits the highest quadratic hyperpolarizability ever reported for an octupolar derivative (lambdamax=482 nm, beta1.91(1 e)=870 x 10(-30) esu, beta0(1 e)=657 x 10(-30) esu). Herein, we demonstrate that the optical and nonlinear optical (NLO) properties are strongly influenced by the symmetry of the complexes, the nature of the ligands (donor endgroups and pi linkers), and the nature of the metallic centers. For example, the length of the pi-conjugated backbone, the Lewis acidity of the metal ion, and the increase of ligand-to-metal ratio result in a substantial enhancement of beta. The contribution of the metal-to-ligand (MLCT) transition to the molecular hyperpolarizability is also discussed with respect to octahedral d6 complexes (M=Fe, Ru).
Correction: A Phosphorescent Nanoparticle‐Based Probe for Sensing and Imaging of (Intra)Cellular Oxygen in Multiple Detection Modalities (2012)

The chemical name of the PFO dye is incorrectly given in the article. The correct name for PFO is poly(9,9-diheptylfluorene-alt-9,9-di-p-tolyl-9H-fluorene), not poly(9,9-dioctylfluorene) as stated in the article.
Discontinuous Polyacrylamide Gel Electrophoresis of DNA Fragments (2003)

At present, the most polymorphic genetic markers are DNA regions composed of a variable number of tandem repeats (VNTRs) (1,2). The detection of VNTRs is made possible by restriction fragment-length polymorphism (RFLP) analysis via Southern blotting (3). The length of each DNA fragment is a function of the number of tandem repeats contained within it. The RFLP technique requires at least 10–50 ng of essentially undegraded DNA (10,000–20,000 bp) and isotopic detection to obtain a result; the time required for analysis may be in excess of one week (4).
Control algorithm of dual arms mobile robot for cooperative works with human (2002)

We propose a motion control algorithm for the dual arm-mobile robot MR Helper, for handling an object in cooperation with a human based on impedance control. The algorithm specifies the apparent impedance of the manipulated object directly with respect to the world frame. It also specifies the apparent impedance of the mobile base relative to the object frame, so as not to influence the motion of the object. The control algorithm is implemented in MR Helper and experimental results obtained illustrate the validity of the proposed algorithm.
Power dissipation and speed tradeoffs associated with optical fan-in (1992)

Optical techniques are projected to possess significant advantage over electronic techniques in implementing global, long distance, high bandwidth, high spatial density interconnects with large fan-in and fan-out. This paper focuses on the impact of large fan-in on the power dissipation of optical switches. Goodman 1 has analyzed the inherent power loss in optical fan-in networks due to the constant brightness theorem. We extend the analysis to include the impact of the fan-in on the power dissipation and speed of an optical link. Both passive (non-regenerative) as well as active (optical detection-regeneration) cases will be analyzed. The connection between these limitations and the performance limits of optical processing architectures based on orthogonally oriented linear modulator arrays (e.g., outer product processors) will also be explored.
VOLTTRON™: Tech-to-Market Best-Practices Guide for Small- and Medium-Sized Commercial Buildings (2016)

VOLTTRON™ is an open-source distributed control and sensing platform developed by Pacific Northwest National Laboratory for the U.S. Department of Energy. It was developed to be used by the Office of Energy Efficiency and Renewable Energy to support transactive controls research and deployment activities. VOLTTRON is designed to be an overarching integration platform that could be used to bring together vendors, users, and developers and enable rapid application development and testing. The platform is designed to support modern control strategies, including the use of agent- and transaction-based controls. It also is designed to support the management of a wide range of applications, including heating, ventilation, and air-conditioning systems; electric vehicles; and distributed-energy and whole-building loads. This report was completed as part of the Building Technologies Office’s Technology-to-Market Initiative for VOLTTRON’s Market Validation and Business Case Development efforts. The report provides technology-to-market guidance and best practices related to VOLTTRON platform deployments and commercialization activities for use by entities serving small- and medium-sized commercial buildings. The report characterizes the platform ecosystem within the small- and medium-sized commercial building market and articulates the value proposition of VOLTTRON for three core participants in this ecosystem: 1) platform owners/adopters, 2) app developers, and 3) end-users. The report also identifies key market drivers and opportunities for open platform deployments in the small- and medium-sized commercial building market. Possible pathways to the market are described—laboratory testing to market adoption to commercialization. We also identify and address various technical and market barriers that could hinder deployment of VOLTTRON. Finally, we provide “best practice” tech-to-market guidance for building energy-related deployment efforts serving small- and medium-sized commercial buildings.
Lipidomic and proteomic characterization of platelet extracellular vesicle subfractions from senescent platelets (2014)

Differential lipid and protein compositions of PL-EVs suggest their unique cellular origins and functions, partly overlapping with PLT granule secretion. Dense PL-MVs might represent autophagic vesicles released during PLT activation and apoptosis and PL-EXs resemble lipid rafts, with a potential role in PLT aggregation and immunity. Segregation of α-synuclein and Aβ precursor protein, ApoE, and ApoJ into less dense and dense PL-MVs, respectively, show their differential carrier role of neurologic disease-related cargo.
Synthetic Studies with 13-Deoxybaccatin III (2002)

An efficient synthesis of 13-epi-7-O-(triethylsilyl)baccatin III from 13-deoxybaccatin III is described. Oxidation of 13-deoxy-7-O-(triethylsilyl)baccatin III with tert-butyl peroxide, followed by reduction with SmI(2), produced 13-epi-7-O-(triethylsilyl)baccatin III in good overall yield. The preparation of 13-oxo-7-O-(triethylsilyl)baccatin III from 13-epi-7-O-(triethylsilyl)baccatin III using tetrapropylammonium perruthenate and N-methylmorpholine N-oxide is also reported.
CT-guided injection of a TRPV1 agonist around dorsal root ganglia decreases pain transmission in swine (2015)

One approach to analgesia is to block pain at the site of origin or along the peripheral pathway by selectively ablating pain-transmitting neurons or nerve terminals directly. The heat/capsaicin receptor (TRPV1) expressed by nociceptive neurons is a compelling target for selective interventional analgesia because it leaves somatosensory and proprioceptive neurons intact. Resiniferatoxin (RTX), like capsaicin, is a TRPV1 agonist but has greater potency. We combine RTX-mediated inactivation with the precision of computed tomography (CT)-guided delivery to ablate peripheral pain fibers in swine. Under CT guidance, RTX was delivered unilaterally around the lumbar dorsal root ganglia (DRG), and vehicle only was administered to the contralateral side. During a 4-week observation period, animals demonstrated delayed or absent withdrawal responses to infrared laser heat stimuli delivered to sensory dermatomes corresponding to DRG receiving RTX treatment. Motor function was unimpaired as assessed by disability scoring and gait analysis. In treated DRG, TRPV1 mRNA expression was reduced, as were nociceptive neuronal perikarya in ganglia and their nerve terminals in the ipsilateral dorsal horn. CT guidance to precisely deliver RTX to sites of peripheral pain transmission in swine may be an approach that could be tailored to block an array of clinical pain conditions in patients.
First record of Polycystididae (Platyhelminthes, Kalyptorhynchia) from Cuba, with the description of a new genus and five new species, and remarks and the description of one new species from Panama (2018)

The first records of Polycystididae from Cuba are provided and discussed. In total nine species have been collected, five of which are new to science, one representing a new genus. Polycydora intermedia gen. n. sp. n. shows intermediate features between Polycystis Kölliker, 1845 and Paulodora Marcus, 1948. The ovaries are kidney shaped, with the oocytes arranged in a row, and lack the hard "nozzles" of Paulodora. A female bursa as in Polycystis is present. In P. intermedia gen. n. sp. n. lacks the strong muscle bulb at the male bursa and the accessory glands type I in the male atrium, which are present in Polycystis. The male atrial organs include a prostate stylet type II connected to a free prostate vesicle type II. The four new species (Phonorhynchoides minor sp. n., Phonorhynchopsis capillaris sp. n., Phonorhynchopsis sublinguatus sp. n., Myobulla armenterosi sp. n.) are distinguished from their congeners by the specific shape and length of the male hard copulatory structures. Phonorhynchoides minor sp. n. has the smallest stylets within the genus, and these stylets are more straight than those of the other species of the genus. In Phonorhynchopsis capillaris sp. n. the prostate stylet type IV is only 20% of the length of the accessory stylet type IV, the lowest relative length within the genus. The accessory stylet in this species is extremely thin; it is only 2 µm wide. Phonorhynchopsis sublinguatus sp. n. has a prostate stylet widened in the distal half, ending in a rounded tip, not twisted in the middle. Because of its strong resemblance to M. armenterosi sp. n., M. berti sp. n., a new species of Myobulla Artois Schockaert, 2000 collected at the Atlantic coast of Panama is described here too. Both species of Myobulla have a prostate stylet type III that shows a 90° turn at some point, as is the case in some other species of Myobulla. In M. berti sp. n. the stylet is smaller overall and is bent in the middle; in M. armenterosi sp. n. the stylet is larger and it is bent more distally. All of the four known species have a very wide geographical distribution: Phonorhynchopsis haegheni, Alcha evelinae, Paraustrorhynchus elixus, and Gyratrix hermaphroditus.
A cis-acting element in the promoter region of the murine c-myc gene is necessary for transcriptional block. (1989)

A block to elongation of transcription has been shown to occur within the first exon of the human and murine c-myc genes. The extent of this block was found to vary with the physiological state of cells, indicating that modulation of the transcriptional block can serve to control the expression of this gene. To determine which sequences are required in cis for the transcriptional block, we generated a series of constructs containing various portions of murine c-myc 5'-flanking and exon 1 sequences. We established populations of HeLa and CV-1 cells stably transfected with these constructs. The transcription start sites were determined by S1 nuclease mapping analysis, and the extent of transcriptional block was measured by nuclear run-on transcription assays. Our results demonstrate that at least two cis-acting elements are necessary for the transcriptional block. A 3' element was found to be located in the region where transcription stopped and showed features reminiscent of some termination sites found in procaryotes. A 5' element was positioned between the P1 and P2 (C. Asselin, A. Nepveu, and K. B. Marcu, Oncogene 4:549-558, 1989). Removal of the more 3' binding site abolished the transcriptional block.

Tyrosine 116 of the Herpes Simplex Virus Type 1 IEα22 Protein Is an Ocular Virulence Determinant and Potential Phosphorylation Site (2003)

The data indicate that Y116 is a determinant of peripheral virulence in mice and that mutations at S34 and Y116 affect virulence independently. The data also show that the S34 and Y116 mutations substantially alter phosphorylation of the alpha22 protein, that Y116 is a potential phosphorylation site, and that the alpha22 protein contains at least two phosphotyrosines. These results are the first to show that mutation of a specific tyrosine in the alpha22 protein is associated with virulence.
Molecular Targets to Promote Central Nervous System Regeneration (2004)

Trauma in the adult mammalian central nervous system (CNS) results in devastating clinical consequences due to the failure of injured axons to spontaneously regenerate. This regenerative failure can be attributed to both a lack of positive cues and to the presence of inhibitory cues that actively prevent regeneration. Substantial progress has been made in elucidating the molecular identity of negative cues present at the CNS injury site following injury. In the past several years, multiple myelin-associated inhibitors including Nogo, Myelin-associated glycoprotein and Oligodendrocyte-myelin glycoprotein have been characterized. Furthermore a neuronal receptor complex and several intracellular substrates leading to outgrowth inhibition have been identified. Rapid progress has also been made in identifying the role of neurotrophins and other positive cues in promoting axonal regrowth. The most recent advances in our understanding of positive stimuli for axon regeneration come from transplantation studies at the CNS lesion site. A number of artificial substrates, tissues, and cells including fetal cells, neural stem cells, Schwann cells and olfactory-ensheathing cells have been tested in animal models of CNS injury. Based on our expanded knowledge of inhibitory influences and on the positive characteristics of various transplants, a number of interventions have been tested to promote recovery in models of CNS trauma. These advances represent the first steps in developing a viable therapy to promote axon regeneration following CNS trauma.
Z-Pinning Approach for Reducing Mechanical Anisotropy of 3D Printed Parts (2018)

The mechanical strength of extrusion-based printed parts is often greatly reduced (25-50%) in the build direction (z-direction) compared to the in-plane strength due to poor bonding between successively deposited layers. This effect can be magnified (75-90% difference) when depositing fiber-reinforced materials or larger print areas with long layer times. Therefore, a patent-pending approach has been developed that deposits material into intentionally aligned voids in the z-direction, allowing continuous material to span multiple layers. The “z-pinning” approach can be applied to several concepts for improving the interlaminar strength of extrusion-based 3D printed parts as well as techniques for applying the technology across a broad spectrum of deposition platforms and material systems. Initial experimental results demonstrate a significant improvement (&gt;3x) in mechanical strength and (&gt;8x) toughness for fiber reinforced components.
