Potentiometric determination of some food additives and their binding to a polycationic species using polyion sensors (2013)

Polycation-sensitive membrane electrodes based on dinonylnaphthalene sulfonate (DNNS) were examined for the determination of some polyanions, namely xanthan (Xanth), alginate (Alg), carboxymethyl cellulose (CMC), and carrageenan (Carr). The potentiometric titrations of polyanionic analytes yielded sharp end points and correlative stoichiometries. After the determinations were successfully performed in saline, these polyanions were also determined in some food products consumed in Bolu (Turkey). In addition, the titration data were used to estimate the interactions between titrant and polyanionic analytes. The equilibrium constants, K_{eq}, and the number of titrant binding sites (n) per mole of analyte polyanion were calculated using Scatchard plots. The accuracy of the assayed method was confirmed by recovery experiments in spiked samples. Dynamic ranges for the determination of polyanionic analytes were 2--20 \mu g/mL for CMC, 1--8 \mu g/mL for Xanth, 0.5--4 \mu g/mL for Alg, and 2--20 \mu g/mL for Carr. LOD values were
Metal-plated plastic waveguide filter using injection molding process (2003)

A metal-plated plastic waveguide filter for Ka-band wireless Internet access systems is presented. As the filter is made using a plastic injection-molding process, the influence of indispensable draft angle on the waveguide walls was precisely considered in the design. By merging this design technique with the high-accuracy molding technique, no electrical tuning was necessary. It also realized the mass-productivity and cost reduction of Ka-band waveguide components.
The activity of thyme essential oil against Acinetobacter spp. (2011)

Abstract The aim of this work was to investigate the antimicrobial properties of thyme essential oil against clinical multiresistant strains of Acinetobacter spp. The antibacterial activity of oil was tested against standard and clinical bacterial strains of Acinetobacter genus. The agar diffusion method was used to check the inhibition of microbial growth at various concentrations of the oil from Thymus vulgaris. Susceptibility testing to antibiotics and chemotherapeutics was prepared using the disc-diffusion method. Identification of bacterial strains was carried out with the Vitek system and confirmed by PCR for Acinetobacter baumanii gyrB gene. The results of experiments showed that the oil from T. vulgaris exhibited an extremely strong activity against all of the clinical strains of Acinetobacter. Thyme oil demonstrated a very good efficacy against multiresistant strains of tested bacteria. Essential oils seems to be an excellent alternative for synthetic preparations and that is reason for an extensive assessment of their antimicrobial activity.
Binding of the basic fibroblast growth factor (bFGF) by soluble components of human umbilical cord. (2002)

Pre-eclampsia, the most common pregnancy associated syndrome, is connected with remodelling of extracellular matrix of the umbilical cord tissues. Since the fibroblast growth factor (FGF) is known to be a stimulator of collagen and glycosaminoglycan biosynthesis, one may expect that it plays an important role in such a remodelling. Studies performed on the umbilical cords of 10 control and 10 pre-eclamptic newborns demonstrated that both the umbilical cord arterial wall and Wharton's jelly contain FGF mainly in complexes with the components of different molecular mass. Pre-eclampsia is associated with a decrease of endogenous FGF-binding by soluble high molecular mass components of the umbilical cord. It is suggested that FGF released from these complexes may be actively bound by fibroblasts of the umbilical cord, stimulating them to produce collagen and sulphated glycosaminoglycans.
Controlling Network Bandwidth to Support Storage QoS (2007)

In network storage environments, it is difficult that a network storage system satisfies each client's service requirements because the specification of QoS requirements is presented as {request size, IOPS, response time ...}, which is used in the existing storage QoS area. Since network storage system has two resources: storage and network, storage QoS requirements to manage two resources effectively, must be specified. In particular, our study considers the TCP/IP-based network. In this paper, to support each client's storage QoS requirements easily, the specification of each client's storage QoS requirements will be presented in terms of bandwidth. The network bandwidth of a storage server must be managed because the storage service can be affected by the network bandwidth. This paper presents the QoS framework regulating the network bandwidth of the storage server to realize the storage performance isolation among the clients. The proposed framework monitors the network resource and the storage resource periodically, identifies the bottleneck resource, selects victims among clients competing for the bottleneck resource and regulates the network bandwidth given to victims to satisfy a client's storage QoS requirements. We implemented the QoS-enabled network storage using the iSCSIprotocol.
Micro aerial vehicle type wall-climbing robot mechanism (2013)

Nowadays, as the building structures are getting taller and taller, the importance of maintenance or inspection of these structures is being increased. However, it has some problems due to the lack of professional manpower and there is a risk in maintaining those areas that are hard to reach, besides the high maintenance cost. The unmanned wall-climbing robots for the areas hard to reach have been researched to solve the problems. The infrastructure-based wall-climbing robots have high payload and safety but the robots need the infrastructure that should be installed on the target structure. The infrastructure is not preferred by the architects since it can be harmful to the exterior of the structure. For this reason, wall-climbing robots that do not need any infrastructure are being researched. Nevertheless, most of the non-infrastructure-based wall-climbing robots are in the laboratory level since the payload, safety and maneuverability are not satisfactory. To overcome these problems, a flight-possible wall-climbing robot mechanism is proposed in this paper. The robot is based on the quadrotor system that is a well-known aerial vehicle using four rotors. It uses thrust forces induced by the four rotors not only to fly but also to stick on the wall. The flight capability makes its maneuverability and safety greatly enhanced. The feasibility of the mechanism is shown through simulations and experiments with a prototype.
A Transductionally Retargeted Adenoviral Vector for Virotherapy of Her2/neu-Expressing Prostate Cancer (2011)

The efficacy of adenovirus (Ad)-based gene therapy of solid tumors, such as prostate cancer, is limited. One of the many problems is that the virus infects many different cell types in the body, resulting in high toxicity, whereas the target cancer cells are often less prone to wild-type Ad infection. Our aim was to develop genetically de- and retargeted Ad vectors to reduce off-target effects and increase target infection for prostate cancer. We have previously reported an Ad5 vector specific for the cancer-associated receptor Her2/neu, created by inserting Her2/neu-reactive Affibody(®) molecules (ZH) into the HI loop of a coxsackievirus and adenovirus receptor binding-ablated fiber (Ad[ZH/1]). In addition to virus retargeting to Her2/neu, this virus was further modified from wild-type Ad by changing the RGD motif in the penton base to EGD and by substitution of the KKTK motif in the third shaft repeat to RKSK, resulting in the vector Ad[ZH/3]. The ZH-containing vectors could be produced to high titers and were specific for their target, resulting in efficient infection and killing of Her2/neu-positive androgen-dependent PC346C prostate cancer cells in vitro. Here we show that the oncolytic Ad[ZH/3] vector significantly prolonged survival time and reduced serum prostate-specific antigen levels in an orthotopic prostate tumor model in nude mice to the same extent as wild-type Ad5. Our results show that Her2/neu targeting using Ad-based vectors for prostate cancer is feasible and may serve as a basis for the development of gene therapy of human prostate cancer as well as other Her2/neu-expressing cancers.
The Nachos instructional operating system (1993)

In teaching operating systems at an undergraduate level,itisvery important toprovide a project that is realistic enough to show how real operating systems work, yet simple enough that the students can understand and modify it in signi cant ways. A number of these instructional systems have been created over the last two decades, but recent changes in hardware and software design, along with the increasing power of available computational resources, have changed the basis for many of the tradeo s made by these systems. We have implemented an instructional operating system, called Nachos, and designed a series of assignments to go with it. Our system includes CPU and device simulators, and runs as a regular UNIX process. Nachos illustrates and takes advantage of modern OS technology, such as threads and remote procedure calls, recent hardware advances, such as RISC&apos;s and the prevalence of memory hierarchies, and modern software design techniques, such as objectoriented programming and distributed computing. We have used Nachos in the undergraduate operating systems class at Berkeley, with positive results. Nachos is freely available, and we would like to see it widely used for undergraduate instruction. 1
Modal analysis and engineering on inp-based two-dimensional photonic-crystal microlasers on a si wafer (2003)

We report results on hexagonal-shaped microlasers formed from two-dimensional photonic crystals (PCs) using InP-based materials transferred and bonded onto SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> / Si wafers. Two types of hexagonal cavities are investigated : single defect (one hole missing) cavities, so-called H1 cavities (1 μm in diameter) and two holes missing per side H2 cavities (2 μm in diameter). Their optical properties are analyzed using photoluminescence experiments, and plane wave method simulations have been performed for comparison. High Q modes (∼600/700) have been measured and they have been shown to enable laser effect at room temperature, under pulsed optical pumping (15% duty cycle and 25-ns pulsewidth). The study of these efficient mode characteristics gives guidance for further improvement of the operation conditions of PC lasers, such as the reduction of the threshold pumping power.
Identification of mouse sphingomyelin synthase 1 as a suppressor of Bax-mediated cell death in yeast (2006)

We have identified mouse sphingomyelin synthase 1 as a novel suppressor of the growth inhibitory effect of heterologously expressed Bax. Yeast cells expressing sphingomyelin synthase 1 were also found to show an increased resistance to a variety of cytotoxic stimuli including hydrogen peroxide, osmotic stress and elevated temperature. Sphingomyelin synthase 1 functions by catalyzing the conversion of ceramide and phosphatidylcholine to sphingomyelin and diacylglycerol. Ceramide is an antiproliferative and proapoptotic sphingolipid whose level increases in response to a variety of stresses. Consistent with its biochemical function, yeast cells expressing sphingomyelin synthase 1 have an enhanced ability to grow in media containing the cell-permeable C2-ceramide analog as well as the ceramide precursor phytosphingosine. We also show that overexpression of AUR1, a potential yeast functional homolog of sphingomyelin synthase, also protects cells from osmotic stress. Taken together, these results suggest that sphingomyelin synthase 1 likely prevents cell death by counteracting stress-mediated accumulation of endogenous sphingolipids.
A ONE-STAGE OPERATION FOR AN ABDOMINAL AORTIC ANEURYSM ASSOCIATED WITH A SEVERELY ATROPHIC RIGHT KIDNEY AND RENAL CELL CARCINOMA IN THE LEFT KIDNEY (1990)

A one-stage operation for an abdominal aortic aneurysm associated with a left renal cell carcinoma was performed on a 73-year-old male. The right kidney of this patient was severely atrophic and total renal function was highly impaired. Upon laparotomy, the aneurysm which was measured 8cm in maximal diameter was found to exist just below the origin of the renal arteries extending to the common iliac arteries. A localized renal cell carcinoma, 3cm in diameter, was recognized in the center of the left kidney which was compensatorily hypertrophied. The right kidney was highly atrophied. With consideration for the quality of life, the replacement of the aneurysm with Y-shaped graft and an enucleation of the renal cell carcinoma were performed at one-stage. Postoperatively, a large amount of fluid from 3000 up to 6000ml/day with a continuous infusion of diuretics was given, resulting in a successful preservation of the renal function without hemodialysis.
A virtual power plant management model based on electric vehicle charging infrastructure distribution (2012)

The exploitation of distributed generation based on intermittent renewable energy sources (RES) has increased the load and generation profile variability. The resort to distributed energy storage systems (DESSs) is usually proposed to compensate the volatility introduced by RES. In particular, plug-in electric vehicles (EVs) are considered one of the most interesting solutions for providing DESSs with the aim of exploiting RES production and matching the distributed electrical generation to the local demand. The aim of this paper is to analyze the impact of vehicle-to-grid technology on an weakly interconnected Virtual Power Plant (VPP) in order to evaluate the effects that distribution and availability of EVs charging structures can have on VPP total cost. A novel mathematical modeling of the mobility system is firstly developed to calculate the probabilistic distribution of parking places. Thereafter, the economic impact on a VPP has been evaluated for different plug-in ratio and charging station scenarios.
Ellagibacter isourolithinifaciens gen. nov., sp. nov., a new member of the family Eggerthellaceae, isolated from human gut (2018)

Urolithins are gut microbial metabolites that exert health benefits in vivo and are generated from ellagic acid (EA) and ellagitannin-containing foods such as strawberries, pomegranates and walnuts. Gordonibacter species produce some intermediary urolithins but the micro-organisms responsible for the transformation of EA into the final and more bioactive urolithins, such as urolithin A and isourolithin A, are unknown. We report here a new bacterium, capable of metabolizing EA into isourolithin A, isolated from healthy human faeces and characterized by determining phenotypic, biochemical and molecular methods. Strain CEBAS 4A belongs to the Eggerthellaceae family and differed from other genera of this family, both phylogenetically and phenotypically. Based on 16S rRNA gene sequence similarity, the strain was related to Enterorhabdus musicola DSM 19490<sup>T</sup> (92.9 % similarity), Enterorhabdus caecimuris DSM 21839<sup>T</sup> (92.7 % similarity), Adlercreutzia equolifaciens DSM 19450<sup>T</sup> (92.5 % similarity), Asaccharobacter celatus DSM 18785<sup>T</sup> (92.5 % similarity) and Parvibacter caecicola DSM 22242<sup>T</sup> (91.2 % similarity). This strain was strictly anaerobic and Gram-stain-positive. The whole-cell fatty acids were saturated (98.3 %), a very high percentage that differs from the nearest genera ranging from 62 to 73 %. The major respiratory lipoquinone was menaquinone-7 and the diamino acid in the peptidoglycan was meso-diaminopimelic acid. Diphosphatidylglycerol and phosphatidylglycerol comprised the main polar lipid profile in addition to several phosphoglycolipids (PGL1-2), phospholipids (PL1-4), glycolipids (GL1-6) and lipids. Based on these data, a new genus, Ellagibacter gen. nov. is proposed with one species, Ellagibacter isourolithinifaciens sp. nov. The type strain of Ellagibacter isourolithinifaciens is CEBAS 4A<sup>T</sup> (=DSM 104140<sup>T</sup>=CCUG 70284<sup>T</sup>).
The High‐Intrinsic Diels−Alder Reactivity of (−)‐Galiellalactone; Generating Four Quaternary Carbon Centers under Mild Conditions (2004)

Abstract The Interleukin‐6 (IL‐6) responsive JAK/STAT pathway seems to be correlated with major diseases such as chronic inflammation, arteriosclerosis, liver fibrosis, Parkinson and Alzheimer disease. In order to take a look at (−)‐galiellalactone as a potential low‐molecular‐weight lead structure for non‐proteinogenic IL‐6 antagonists we carried out a microderivatization program that was aiming at bioactive congeners of the natural product and a preliminary structure‐activity relationship. During this effort, galiellalactone showed reactivity generally governed by convex‐concave face selectivity. O ‐Acyl derivatives of galiellalactone turned out to be precursors of bis(dehydratogaliellalactone), a novel oligocyclic Diels−Alder product of complicated architecture. During this extraordinary Diels−Alder‐type conversion four quaternary carbon centers were generated at room temperature under mild conditions in a regio‐ and stereoselective fashion. The novel Diels−Alder transformation was used for a stereoselective hetero‐derivatization of the natural product leading to an aza congener of altered IL‐6 antagonistic activity in HepG2 hepatoma cells. The absolute (4 S ,5a R ,7a R ,7b S ) configuration of natural (−)‐galiellalactone was confirmed by X‐ray crystallography with Cu‐ K α radiation. (© Wiley‐VCH Verlag GmbH & Co.

Recent issues on integral imaging and its applications (2013)

In this review paper, the recent progress of 3D applications using integral imaging is introduced. Thanks to the progress of the flat panel displays, the quality of the 3D displays has also improved, resulting in the opening of more applications of the 3D display. The previous studies on integral imaging emphasized the improvement of the viewing quality of the integral imaging system, but the emergence of new technologies requires more than the replacement of the current 2D displays. New applications of the integral imaging method, such as displays with augmented reality, 3D information capturing, real-time processing, the projection-type method, and the integral floating method, and their recent research trends, are introduced.

Parallel 3D Delaunay Triangulation (1993)

Abstract The paper deals with the parallelization of Delaunay triangulation algorithms, giving more emphasis to pratical issues and implementation than to theoretical complexity. Two parallel implementations are presented. The first one is built on De Wall, an Ed triangulator based on an original interpretation of the divide & conquer paradigm. The second is based on an incremental construction algorithm. The parallelization strategies are presented and evaluated. The target parallel machine is a distributed computing environment, composed of coarse grain processing nodes. Results of first implementations are reported and compared with the performance of the serial versions running on a Unix workstation.
Quick response barcode deblurring via <i>L</i> <sub>0</sub> regularisation based sparse optimisation (2019)

In recent years, the two‐dimensional barcode techniques have been widely applied in a large number of fields due to the requirement for the development of information acquisition technology. Also, the identification and verification of the static barcodes could be implemented flawlessly. However, the recognition of the motion blurred two‐dimensional barcode images still remains a challenge to most of the current machine vision systems. To address the above‐mentioned problem, the authors propose a regularisation‐based approach to reverse the blurry barcode images while taking the number of black and white blocks in the two‐dimensional barcode image as the prior. To evaluate the performance of the proposed approach, they conducted comparison experiments between state‐of‐the‐art image deblurring methods and ours. Experimental results on synthetically blurry barcode images show that the proposed method outperforms the state‐of‐the‐art image restoration techniques.
A novel biomagnetic method to study gastric antral contractions (1997)

A novel non-invasive method to study the motion associated with gastric antral contractions is discussed. The method is based on magnetic flux changes detected by an a.c. biosusceptometer, produced by a magnetic test meal within the stomach. Measurements are made at the surface of the torso and are easy to perform. Simultaneous measurements were made with electrogastrography and scintigraphy showing remarkable coincidence. The effect of a drug on the amplitude of antral contractions was also assayed with the new method.
Identification of Ectonucleotidases CD39 and CD73 in Innate Protection during Acute Lung Injury (2007)

Acute lung injury (ALI), such as that which occurs with mechanical ventilation, contributes to morbidity and mortality of critical illness. Nonetheless, in many instances, ALI resolves spontaneously through unknown mechanisms. Therefore, we hypothesized the presence of innate adaptive pathways to protect the lungs during mechanical ventilation. In this study, we used ventilator-induced lung injury as a model to identify endogenous mechanisms of lung protection. Initial in vitro studies revealed that supernatants from stretch-induced injury contained a stable factor which diminished endothelial leakage. This factor was subsequently identified as adenosine. Additional studies in vivo revealed prominent increases in pulmonary adenosine levels with mechanical ventilation. Because ectoapyrase (CD39) and ecto-5'-nucleotidase (CD73) are rate limiting for extracellular adenosine generation, we examined their contribution to ALI. In fact, both pulmonary CD39 and CD73 are induced by mechanical ventilation. Moreover, we observed pressure- and time-dependent increases in pulmonary edema and inflammation in ventilated cd39(-/-) mice. Similarly, pharmacological inhibition or targeted gene deletion of cd73 was associated with increased symptom severity of ventilator-induced ALI. Reconstitution of cd39(-/-) or cd73(-/-) mice with soluble apyrase or 5'-nucleotidase, respectively, reversed such increases. In addition, ALI was significantly attenuated and survival improved after i.p. treatment of wild-type mice with soluble apyrase or 5'-nucleotidase. Taken together, these data reveal a previously unrecognized role for CD39 and CD73 in lung protection and suggest treatment with their soluble compounds as a therapeutic strategy for noninfectious ALI.
