Selenoprotein induced M1 to M2 murine macrophage phenotype switching is imperative in helminth parasite clearance (2012)

Selenium (Se) in the form of selenoproteins, imparts many beneficial health and anti‐inflammatory properties. In the present study, we investigated the anti‐inflammatory activity of Se using a LPS and IL4 treated murine BMDM model. IL4‐treated macrophages supplemented with 100 nM Se significantly increased the expression of alternatively activated macrophage (M2) markers, Arg‐I and Mrc‐1. Se treatment also increased the enzymatic activity of Arg‐I and surface expression of Mrc‐1. Conversely, expression of classically activated macrophage (M1) markers, TNFα, and IL1β, were significantly decreased in LPS treated macrophages cultured in 100 nM Se and IL4, suggesting a synergistic effect of Se and IL4. Additional studies utilizing tRNA [Ser]Sec (Trsp) KO mice macrophages, characterized by a total loss of selenoprotein expression, showed a complete abrogation of Arg‐I activity, even under high Se (250nM) conditions, demonstrating the importance of selenoproteins. Current in vivo studies, using the helminthic parasite Nippostrongylus brasiliensis , show a significant increase in intestinal M2 marker expression, in addition to a decreased presence of intestinal adult worms and fecal eggs, in Se supplemented mice. These data suggest that optimal selenium status, in the form of selenoproteins, is critical to skew macrophage activation to promote resolution of (parasite) infection. NIH grant DK077152.
High temperature mechanical properties of cast as well as powder metallurgical manufactured metallic foams (2004)

This work deals with studying the high temperature mechanical properties of different types of metallic foams. The foams which have been used in this work were manufactured by two different processing methods. Al-foams (trade-name Alporas) were processed by a melt metallurgical route whereas Distaloy as well as Astaloy foams which are based on low-alloyed steel powders, were manufactured by a newly developed method. This method which is known as Slip Reaction Foam Sintering (SRFS)-process, belongs to the powder metallurgical route. High temperature compressive tests were carried out, in air as well as in argon, on foams having different densities in a variable range of temperature. The effect of the foam density, test temperature, size of the specimen as well as the strain rate on the mechanical properties was studied. Moreover, Alporas foams have been undergone creep tests in air. The effect of the foam density, test temperature and the applied stress on determining the creep properties was studied as well.

TMPRSS2:ERG gene aberrations may provide insight into pT stage in prostate cancer (2016)

Our results indicate that it is possible to predict pT3 stage at final histology from TMPRSS2:ERG gene fusion at initial core needle biopsy. FISH determination of TMPRSS2:ERG gene fusion may be particularly useful for patients scheduled to undergo a radical prostatectomy in order to improve oncological and functional results.
Repetition rate multiplication of optical pulses using fiber Bragg gratings (2003)

In this paper, a simple method for repetition rate multiplication of optical pulses using a number of fiber Bragg gratings is demonstrated, where the required positioning accuracy in the grating formation was only 1 /spl mu/m. The lack of narrow passbands in the proposed method, provides stability for the multiplied pulses. We propose a simple method of control for each of the gratings in the writing process. We also demonstrate the use of true repetition rate multiplication for compensation of fiber dispersion.
Adult Donor Rod Photoreceptors Integrate into the Mature Mouse Retina (2011)

Fully mature photoreceptors retain the ability to integrate into the mature retina. The authors propose that their potential for integration is limited primarily by their decreased survival after dissociation.

Straight Leg Raise Test: Influence of Lumbosant© and Assistant Examiner in Hip, Pelvis Tilt and Lumbar Lordosis (2020)

The passive straight leg raise (PSLR) test is widely used to assess hamstring extensibility. However, to accurately measure hamstring extensibility throughout PSLR, appropriate stabilization of the pelvis must be provided in order to minimize the possible influence of any compensatory movement in the scores reached. The main purpose of this study was to demonstrate the degree of influence of the Lumbosant© and an assistant examiner in hamstring extensibility in healthy young adults. A secondary objective was to verify the variability of the posterior pelvic tilt movement. Hamstring muscle extensibility was measured using the traditional (only an examiner) and new (using a low-back protection support Lumbosant© and two trained [principal and assistant] examiners) PSLR procedures. Correlation coefficients were expressed using r values, accompanying descriptors and 90% confidence intervals. Variance explained was expressed via the R2 statistic. To examine possible differences, the Mann-Whitney U-test was conducted. Additionally, Cohen’s d was calculated for all results, and the magnitudes of the effect were interpreted and statistical significance set at p &lt; 0.05. A stepwise multiple regression analysis was performed to examine the relationship between scores and values. The final score that was determined with the new PSLR is significantly lower (13° approximately) than the one obtained through the traditional procedure (75.3 ± 14.4° vs. 89.2 ± 20.8°; d = −0.777 [moderate]). The data presented in this study suggest that the PSLR may overestimate hamstring extensibility unless lumbopelvic movement is controlled. Therefore, we recommend the use of Lumbosant© and an auxiliary examiner to obtain more accurate hamstring extensibility scores.

The effect of Mn additions on the hysteresis loss and critical current density of power-metallurgy processed superconducting Nb/sub 3/Sn wires (1993)

Powder-metallurgy processed Nb/sub 3/Sn conductors were fabricated using a (Cu-1 or 3 wt.% Mn)-22.5 wt.%Nb composite. Plasma rotating electrode processed powders were used to improve workability. The Mn addition to the matrix increased the critical current density. The overall critical current density was about 1.5 approximately 2 times higher than that of conductors without Mn addition. It was found that Mn addition enhanced the reaction rate of Nb/sub 3/Sn through a catalysis-like effect of Mn. The Mn addition to the matrix decreased the hysteresis loss and the effective filament diameter. The lowest hysteresis loss was about 60% of the value of conductors without Mn addition. It was found that Mn addition depressed interfilamentary coupling.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Huddling in groups leads to daily energy savings in free‐living African Four‐Striped Grass Mice, Rhabdomys pumilio (2006)

Summary Free‐living animals make complex decisions associated with optimizing energy and nutrient intake. In environments where ambient temperatures fall below the thermoneutral zone, homeotherms must choose whether or not to forage, how long and what to forage for, and whether or not to perform activities that conserve energy. Huddling in groups has long been thought of as a possible means of conserving energy. Laboratory studies have shown that at low ambient temperatures individuals in groups expend less energy than individuals by themselves. However, studies have yet to demonstrate that thermoregulatory savings can have an impact on the overall daily energy expenditure (DEE) of free‐living animals. Here we show that, in the laboratory, African Four‐Striped Grass Mice ( Rhabdomys pumilio ) expend less energy per individual in large groups than smaller groups. We also show that when free‐living groups were experimentally reduced to one‐half of their original size, DEE and water turnover increased by 19% and 37%, respectively. The magnitudes of the reduction in free‐living DEE were comparable with calculated energy savings from the laboratory. One of the reasons why this species may sometimes occur in groups is that energetic benefits can be gained through huddling in habitats in which food and water are scarce.
Impact of copper-catalyzed cross-coupling reactions in natural product synthesis: the emergence of new retrosynthetic paradigms (2013)

Copper-catalyzed Ullmann-Goldberg-type cross-coupling reactions have undergone nothing short of a renaissance over the last decade and an impressive number of procedures are now available for the formation of C-N, C-O and C-S bonds with remarkable efficiencies and surgical precision. These reactions have been recently integrated into natural product synthesis, which clearly resulted in the emergence of new retrosynthetic paradigms and bond disconnections. The impact of copper-catalyzed cross-coupling reactions in natural product synthesis will be overviewed in this article with an emphasis on the evolution of strategies due to copper catalysis, mostly by comparison with alternative tactics and their relative efficiencies.

A new injection method for AC harmonic elimination by active power filter (1988)

An injection method for an active filter which eliminates the harmonics present in AC lines by injecting PWM harmonic compensating current is proposed. In the proposed method, the active filter produces a pulsewidth modulation (PWM) current that cancels the existing harmonics up to any order completely. To generate such PWM current, both inverter and DC current source is needed. The current source can be replaced by a large inductor without any external power source. This can be achieved by providing the inverter with rectifying capability because the inverter has the same circuit structure as the rectifier. Therefore, the proposed model of PWM injection current includes not only the harmonic components to suppress the existing harmonics up to any order, but also the fundamental one, to raise the inductor current to any desired value. The characteristics of the injection method are investigated through a digital computer simulation. Feasibility is proved by the experimental results.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

One-Size-Fits-All Wireless Video. (2009)

Abstract — We present SoftCast, a new approach for wireless video that flips the conventional design; instead of requiring the source to pick an 802.11 bitrate and video resolution before transmission, it allows the receiver to decode a video whose bitrate and resolution are commensurate with the observed channel quality after reception. This approach has applications for multicast and mobile wireless receivers, whose channels differ across time and space. I.
Automotive Electrical and Electronic Architecture Security via Distributed In-Vehicle Traffic Monitoring (2017)

Due to the growing interconnectedness and complexity of in-vehicle networks, in addition to safety, security is becoming an increasingly important topic in the automotive domain. In this paper, we study techniques for detecting security infringements in automotive electrical and electronic (E/E) architectures. Toward this we propose in-vehicle network traffic monitoring to detect increased transmission rates of manipulated message streams. Attacks causing timing violations can disrupt safety-critical functions and have severe consequences. To reduce costs and prevent single points of failure, our approach enables an automatic distribution of detection tasks among selected E/E architecture components, such as a subset of electronic control units. First, we analyze a concrete E/E system architecture to determine the communication parameters and properties necessary for detecting security attacks. These are then used for a parametrization of the corresponding detection algorithms and the distribution of attack detection tasks. We use a lightweight message monitoring method and optimize the placement of detection tasks to ensure a full-coverage of the E/E system architecture and a timely detection of an attack.
Energy Saving Pump Control System with Micro-Computer (1985)

A new energy saving pump control system has been developed for ship. This system consists of a cooling sea water pump, control valve of sea water line, microcomputer, transistor inverter, etc. While conventionally the pump is run continuously at a given speed and surplus sea water is supplied with various auxiliary machineries in many conditions, this new developed system provides proper amount of sea water with auxiliary machineries by the control valve and variable speed pump with a microcomputer and transistor inverter.The first plant of this system was installed on the container ship and we confirmed that the function of this system was satisfactory.
Method for generating a photonic NOON state with quantum dots in coupled nanocavities (2017)

We propose a method to generate path-entangled NOON-state photons from quantum dots and coupled nanocavities. In the systems we considered, cavity mode frequencies are tuned close to the biexciton two-photon resonance. Under appropriate conditions, the system can have the target NOON state in the energy eigenstate, as a consequence of destructive quantum interference. The NOON state can be generated by a resonant laser excitation. This method, first introduced for a two-photon NOON state ($N=2$), can be extended toward a higher NOON state ($N&gt;2$) based on our recipe, which is applied to the case of $N=4$ as an example.

Diatomaceous Silica in Environmental Applications: A Case Study from the Lacustrine Deposit of Limnos Island, Aegean Sea, Greece (2022)

Diatomitic and clastic-volcanoclastic marly samples from the Paranisia area of Limnos Island, were studied mineralogically by X-ray diffraction (XRD), chemically by X-ray fluorescence spectroscopy (XRF) and morphologically by scanning electron microscopy (SEM-EDS), together with some physical properties such as the insulation block density, specific surface area and porosity. The diatomaceous samples were classified as porcelaneous or clayey (moler type) diatomite. Opal-CT forms microplates disseminated in the groundmass and are diagenetically formed in expense of opal-A dissolution. The purest diatomaceous beds have been transformed into opaline beds (opal-CT-rich rocks), whereas the clayey beds were not influenced by diagenetic transformations. The studied diatomites from Limnos Island are suitable materials for environmental uses, as an absorbent, for the production of insulation bricks or as lightweight aggregates.
Graphene as a subnanometre trans-electrode membrane (2010)

DNA sequencing: enter the graphene nanopore Atomically thin layers of graphite — known as graphene — are highly electronically conducting across the plane of the material. Now researchers from Harvard University and the Massachusetts Institute of Technology show that, when used as a membrane separating two liquid reservoirs, graphene is strongly ionically insulating, while its in-plane electronic properties are strongly dependent on the inter-facial environment. The membrane prevents ions and water from flowing through it, but can attract various ions and other molecules to its two atomically close surfaces. A variety of analytical applications may result. For instance, the authors show that by drilling pores a few nanometres in diameter into these 'trans-electrode' membranes, it is possible to thread a long DNA molecule through the graphene nanopore. The DNA blocks the flow of ions, resulting in a characteristic electrical signal reflecting the size and conformation of the molecule. Such a system has potential as the basis of devices that could significantly reduce the cost of DNA sequencing.
Loss and thermal estimation method of a magnetic bearing system considering electromagnetic and temperature coupling (2017)

The stability of magnetic bearings will seriously affect the overall operation of the motor. Magnetic bearing temperature is closely related to the performance of magnetic bearing (MB) system. Therefore, loss calculation and thermal estimation are very important in the design of MB system. A MB system including a pure radial magnetic bearing (RMB) and a combined radial and axial magnetic bearing (CRAMB) was designed for a high-speed permanent magnet motor. An approach of loss and temperature field calculation considering electromagnetic and temperature coupling was proposed. Two electrical machines supported by this MB system, whose power is 30kW and related speed is 36000rpm have been developed for experiment. The experimental results verify the validity and accuracy of this method.
A biochemical logic approach to biomarker-activated drug release (2012)

The present study aims at integrating drug-releasing materials with signal-processing biocomputing systems. Enzymes alanine transaminase (ALT) and aspartate transaminase (AST)—biomarkers for liver injury—were logically processed by a biocatalytic cascade realizing a Boolean AND gate. Citrate produced in the system was used to trigger a drug-mimicking release from alginate microspheres. In order to differentiate low vs. high concentration signals, the microspheres were coated with a protective shell composed of layer-by-layer adsorbed poly(L-lysine) and alginate. The alginate core of the microspheres was prepared from Fe3+-cross-linked alginate loaded with rhodamine 6G dye mimicking a drug. Dye release from the core occurred only when both biomarkers, ALT and AST, appeared at their high pathophysiological concentrations jointly indicative of liver injury. The signal-triggered response was studied at the level of a single microsphere, yielding information on the dye release kinetics.
Expression of cloned imunoglobulin genes introduced into mouse L cells (1983)

Functionally rearranged immunoglobulin heavy-chain (gamma 2b) and light-chain (lambda 1 and kappa) genes were introduced into mouse L tk- cells by co-transformation with the Herpes virus tk gene. Cloned cell lines were selected in HAT medium and tested for the presence of transfected immunoglobulin gene sequences by Southern blotting analysis. It was found that the gamma 2b gene was accurately transcribed at a low level in transfected mouse L cells and cytoplasmic gamma 2b, heavy-chain protein was detected by immunoprecipitation of cell extracts. Light-chain genes, on the other hand, were not accurately transcribed. Instead, lambda 1 or kappa RNA species were detected which were approximately 200 to 300 bases longer than the authentic mRNAs. These results suggest that the expression of rearranged heavy-chain and light-chain genes are controlled differently and that these differences can be seen in transfected, non-lymphoid cells.
