Astroglia Contain a Specific Transport Mechanism for <i>N</i>‐Acetyl‐<scp>l</scp>‐Aspartate (1999)

N-Acetylaspartate (NAA) is the second most abundant amino acid in the adult brain. It is located and synthesized in neurons and probably degraded in the glia compartment, but the transport mechanisms are unknown. Rat primary neuron and astrocyte cell cultures were exposed to the L isomer of [3H]NAA and demonstrated concentration-dependent uptake of [3H]NAA with a Km approximately 80 microM. However, Vmax was 23+/-6.4 pmol/mg of protein/min in astrocytes but only 1.13+/-0.4 pmol/mg of protein/min in neurons. The fact that neuron cultures contain 3-5% astrocytes suggests that the uptake mechanism is expressed only in glial cells. The astrocyte uptake was temperature and sodium chloride dependent and specific for L-NAA. The affinity for structural analogues was (IC50 in mM) as follows: L-NAA (0.12) > N-acetylaspartylglutamate (0.4) > N-acetylglutamate (0.42) > L-aspartate (>1) > L-glutamate (>1) > or = DL-threo-beta-hydroxyaspartate > N-acetyl-L-histidine. The naturally occurring amino acids showed no inhibitory effect at 1 mM. The glutamate transport blocker trans-pyrrolidine-2,4-dicarboxylate exhibited an IC50 of 0.57 mM, whereas another specific glutamate transport inhibitor, DL-threo-beta-hydroxyaspartate, had an IC50 of >1 mM. The experiments suggest that NAA transport in brain parenchyma occurs by a novel type of sodium-dependent carrier that is present only in glial cells.

Recent advances in materials and flexible electronics for peripheral nerve interfaces (2018)

Peripheral nerve interfaces are a central technology in advancing bioelectronic medicines because these medical devices can record and modulate the activity of nerves that innervate visceral organs. Peripheral nerve interfaces that use electrical signals for recording or stimulation have advanced our collective understanding of the peripheral nervous system. Furthermore, devices such as cuff electrodes and multielectrode arrays of various form factors have been implanted in the peripheral nervous system of humans in several therapeutic contexts. Substantive advances have been made using devices composed of off-the-shelf commodity materials. However, there is also a demand for improved device performance including extended chronic reliability, enhanced biocompatibility, and increased bandwidth for recording and stimulation. These aspirational goals manifest as much needed improvements in device performance including: increasing mechanical compliance (reducing Young's modulus and increasing extensibility); improving the barrier properties of encapsulation materials; reducing impedance and increasing the charge injection capacity of electrode materials; and increasing the spatial resolution of multielectrode arrays. These proposed improvements require new materials and novel microfabrication strategies. This mini-review highlights selected recent advances in flexible electronics for peripheral nerve interfaces. The foci of this mini-review include novel materials for flexible and stretchable substrates, non-conventional microfabrication techniques, strategies for improved device packaging, and materials to improve signal transduction across the tissue-electrode interface. Taken together, this article highlights challenges and opportunities in materials science and processing to improve the performance of peripheral nerve interfaces and advance bioelectronic medicine.
Alumina-supported CO hydrogenation catalysts prepared from molecular osmium and ruthenium clusters (1981)

Os catalysts on γ-Al2O3 supports have been prepared from Os complexes of varying nuclearity, namely H2OsCl6, Os3(CO)12, H4Os4(CO)12 and Os6(CO)18. Characterization by infrared and X-ray photoelectron spectroscopy and transmission electron microscopy provides evidence of the stabilization of well-defined ensembles of Os atoms on the support surface, the ensemble size being determined by the nuclearity of the cluster precursor. The catalysts prepared from H2OsCl6 have a dispersion comparable with that obtained with Os3(CO)12, although the presence of smaller ensembles and single atoms cannot be excluded. The ensemble size may influence activity and selectivity for C2 and higher hydrocarbons in CO hydrogenation at atmospheric pressure and temperatures between 530 and 610 K, but the results suggest that the heterogeneity of the Os species and the chlorine content of the support also influence the catalyst performance. Data obtained with a more highly dispersed Ru/Al2O3 catalyst prepared from Ru3(CO)12 provide the first quantitative comparison between Os and another Group VIII metal catalyst for CO hydrogenation. The Os was approximately one order of magnitude less active than the Ru catalyst, but it was more selective for formation of C2 and C3 hydrocarbons.

Cor triatriatum and anomalous pulmonary venous return: an unusual case. (1990)

In December 1954, a 29-year-old man with cor triatriatum underwent partial surgical repair consisting of left atrial implantation of a single anomalous pulmonary vein that had been draining into the innominate vein. In April 1989, at age 64, he returned for definitive cardiac repair. The contrast between these 2 procedures illustrates the tremendous progress that has been made in cardiac diagnosis and surgery during the past 35 years.
XAS In Situ Cell for Measurements of Mn and Fe Promoted Sulfated Zirconia Catalysts (2005)

Promotion of sulfated zirconia (SZ) with Mn or Fe results in an orders of magnitude more active catalyst for the skeletal isomerization of n-butane. One explanation for this promotion effect, consistent with rapid deactivation observed for these catalysts, suggests that the promoter participates in non-catalytic redox reactions. In order to test this hypothesis it was necessary to measure the Mn valence under reaction conditions (in situ). However, it was found that the catalysts have a reduced activity when pressed into pellets for measurement. Therefore, we designed an in situ cell that could be used to measure spectra of a powdered catalyst sample. The cell consists of an internal powder bed reactor (heatable to 773 K), which is enclosed in a He-filled, temperature controlled outer cell to ensure that the window to the inner cell, and the catalyst it contacts, are at a well-defined temperature. The reactor characteristics of the new cell are shown to be comparable to those of a quartz tubular reactor. Spectra are measured in fluorescence mode with simultaneous measurement of a reference foil in transmission using a section of the beam that bypasses the catalyst bed. Contrary to previous reports, data obtained in situ, show that the Mn valence remains constant during reaction with n-butane (333 K) after the catalyst has been activated in He. Additionally, EXAFS measurements indicate that the local environment of the Mn changes significantly during activation in He. Neither the XANES, nor the EXAFS for the Fe K-edge of FeSZ change during activation or reaction. These results suggest that the promotion effect is either catalytic, or is indirect, perhaps through modification of the zirconia bulk.
Regulation of Class II MHC Expression in APCs: Roles of Types I, III, and IV Class II Transactivator (2002)

Class II transactivator (CIITA) is necessary for expression of class II MHC (MHC-II) molecules. In mice, CIITA expression is regulated by three promoters (pI, pIII, and pIV), producing types I, III, and IV CIITA. The relative roles of different CIITA types remain unclear. Unstimulated bone marrow-derived macrophages expressed low levels of CIITA mRNA; type I CIITA was nine times more abundant than type IV (type III CIITA was barely detected). Exposure to IFN-gamma (6 h) dramatically increased types I and IV CIITA mRNA to similar absolute levels. Type IV CIITA declined over time, but type I was stable for over 72 h. Thus, the dominant form of CIITA evolved with time during activation by IFN-gamma, and type I CIITA explained prolonged expression of MHC-II by macrophages. mRNA half-life was shorter for type I than type IV CIITA, suggesting that sustained transcription contributed to stable expression of type I CIITA induced by IFN-gamma. Splenic B cells expressed mRNA for type III CIITA but very little for types I or IV. Treatment with IL-4 increased surface expression of MHC-II protein, but mRNA for MHC-II and CIITA (total, I, III, and IV) remained unchanged, suggesting posttranslational regulation. Splenic dendritic cells expressed type I CIITA but little type III or IV; CpG DNA induced their maturation and decreased types I and III CIITA, consistent with decreased MHC-II protein synthesis. CIITA types differ in regulation in various APCs under different stimuli, and the predominant type of CIITA varies at different stages of APC activation.
Reactive Oxygen and Targeted Antioxidant Administration in Endothelial Cell Mitochondria (2006)

We used fluorescent probes and EPR to study the mechanism(s) underlying reactive oxygen species (ROS) production by endothelial cell mitochondria and the action of mitoquinol, a mitochondria-targeted antioxidant. ROS measured by fluorescence resulted from complex I superoxide released to the matrix and converted to H(2)O(2). In contrast, EPR largely detected superoxide generated at complex III and effluxed outward. ROS fluorescence by mitochondria fueled by the complex II substrate, succinate, was substantial but markedly inhibited by rotenone. Superoxide, detected by EPR, in succinate-fueled mitochondria was not inhibited by rotenone and likely derived from semiquinone formation at complex III. Mitoquinol decreased H(2)O(2) fluorescence by succinate-fueled mitochondria but had little effect on the EPR signal for superoxide. This was not associated with a detectable decrease in membrane potential. Mitoquinol markedly enhanced ROS fluorescence in mitochondria fueled by the complex I substrates, glutamate and malate. Inhibitor studies suggested that this occurred in complex I, at one or more Q binding pockets. The above effects of mitoquinol were determined in mitochondria isolated and subsequently exposed to the targeted antioxidant. However, similar effects were observed in mitochondria after antecedent exposure to mitoquinol/mitoquinone in culture, suggesting that the agent is retained after isolation of the organelles. In conclusion, ROS production in bovine aortic endothelial cell mitochondria results largely from reverse transport to complex I and through the Q cycle in complex III. Mitoquinol blocks ROS from reverse electron transport but increases superoxide production derived from forward transport. These effects likely occur at one or more Q binding sites in complex I.
Regional Association-based Fine-mapping for Sodium-Lithium Countertransport on Chromosome 10 (2007)

The Synthesis and Structural Characterization of Na3WO3N (1994)

We report the discovery of a new ternary oxynitride, Na3WO3N. Na3WO3N is synthesized by exposing a eutectic melt consisting of 12Na2O : 1Na2WO4 to a flow of ammonia gas at 695°C. The compound crystallizes in the acentric space group Pmn21 with a = 7.2481(3) Å, b = 6.2728(3) Å, and c = 5.6493(2) Å. The structure was determined from synchrotron X-ray powder diffraction data and refined using the Rietveld analysis on neutron powder diffraction data. It is isostructural to the low temperature form of Li3PO4 which can be derived from an ordered wurtzite structure-type with all the atoms having tetrahedral coordination. Alternatively, the structure can be described as being "salt-like" consisting of isolated (WO3N)-3 tetrahedral polyanions separated by Na+.
Photodissociation dynamics of I 3<sup>-</sup>using femtosecond photoelectron spectroscopy (1998)

The photodissociation dynamics of gas phase I<SUB>3</SUB> following 390 nm excitation are studied with femtosecond photoelectron spectroscopy. Both I and I<SUB>2</SUB> photofragments are observed; the I<SUB>2</SUB> exhibits coherent oscillations with a frequency corresponding to an average vibrational level ((upsilon) ) equals 67. The oscillations dephase by 4 ps and rephase by approximately 45 ps. This can be understood by considering the dynamics of a coherent superposition of vibrational states on the anharmonic I<SUB>2</SUB> potential. Our results represent the first example of coherently produced photodissociation products undergoing dynamical rephasing. Also for the first time the gas phase frequency of ground state I<SUB>3</SUB> is determined via a resonance impulsive stimulated Raman scattering process. Finally, the photoelectron spectrum of I<SUB>3</SUB> yields the vertical detachment energy of I<SUB>3</SUB> and the spacing between the first two electronic states of the neutral I<SUB>3</SUB> molecule. The photodissociation dynamics of gas phase I<SUB>3</SUB> differ considerably from those observed in condensed phase experiments.
Chloride penetration and carbonation in self-compacting concrete (2006)

This mission is achieved through collaboration of leading experts in construction practice and science including academics, researchers, industrialists, testing laboratories and authorities.
A Menagerie of Tracks at Maryland: HARD, Enterprise, QA, and Genomics, Oh My! (2006)

This year, the University of Maryland participated in four separate tracks: HARD, enterprise, question answering, and genomics. Our HARD experiments involved a trained intermediary who searched for documents on behalf of the user, created clarification forms manually, and exploited user responses accordingly. The aim was to better understand the nature of single-iteration clarification dialogs and to develop an “ontology of clarifications” that can be leveraged to guide system development. For the enterprise track, we submitted ocial runs to the Known Item Search and the Discussion Search tasks. Document transformation to normalize dates and version numbers was found to be helpful, but suppression of text quoted from earlier messages and expansion of the indexed terms for a message based on subject line threading proved to not be. For the QA track, we submitted a manual run of “other” questions in an eort to quantify human performance on the task. Our genomics track participation was in collaboration with the National Library of Medicine, and is primarily reported in NLM’s overview paper.
Single crystal SiC capacitive pressure sensor at 400°C (2004)

Single crystal 3C-SiC capacitive pressure sensors are proposed for high-temperature sensing applications. The prototype device consists of an edge-clamped circular SiC diaphragm with a radius of 400 /spl mu/m and a thickness of 0.5 /spl mu/m suspended over a 2 /spl mu/m sealed cavity on a silicon substrate. The fabricated sensor demonstrates a high-temperature sensing capability up to 400/spl deg/C, limited by the test setup. At 400/spl deg/C, the device achieves a linear characteristic response between 1100 torr and 1760 torr with a sensitivity of 7.7 ff/torr, a linearity of 2.1%, a hysterisis of 3.7%, and a sensing resolution of 9.1 torr (12 mbar).
Robust texture sengmentation algorithm based on the Fourier spectrum analysis (2002)

This paper presents a segmentation algorithm for image processing, which is able to distinguish the background's area from the object's area based only on their texture characteristics. The main goal is to develop a segmentation algorithm which does not need any prior information about the object (form, colours, textures, brightness etc.) and which is also robust against industrial conditions (such as shadow effects and electromagnetic noise). The developed solution is based on a predefined and structured background (with a specific frequency in the grey values). The background frequency is compared with the object's texture frequency using a Fourier analysis together with a classification algorithm. Two different types of classification algorithms have been applied: statistical covariance analysis and Neural Networks. The algorithm has been evaluated using real textile images under distinct conditions showing a very appropriated result with a segmentation error smaller than 0,5 percent in the average. The paper finishes with a set of conclusions and perspectives for future works.

Characterisation of the anti-apoptotic function of survivin-ΔEx3 during TNFα−mediated cell death (2007)

Survivin is an oncogenic protein involved in cell division and acts as an anti-apoptotic factor. It is highly expressed in most cancers and is associated with chemotherapy resistance, increased tumour recurrence, and shorter patient survival. This makes anti-survivin therapy an attractive cancer treatment strategy. These functions are mediated by several survivin spliced variants, whose expression may correlate with cancer progression. One of the spliced variants, survivin-DeltaEx3, is known to inhibit apoptosis, through undefined mechanisms. Here, we characterised these mechanisms upon TNFalpha-mediated apoptosis, and showed that survivin-DeltaEx3 acts as an adaptor, allowing the formation of a complex between Bcl-2 and activated caspase-3. The Bcl-2/survivin-DeltaEx3 complex, but not survivin-DeltaEx3 itself, inhibits the activity of caspase-3. Bcl-2 is therefore linked to the postmitochondrial apoptotic machinery by survivin-DeltaEx3. Thus, survivin-DeltaEx3 plays a key role in the inhibition of caspase-3 activity, and in the control of the mitochondrial checkpoint of apoptosis. This study suggests that targeting survivin-DeltaEx3, rather than survivin alone, could be relevant for treating human cancers.
