Review of Research in Japan on Electromagnetic Force Induced Vibration and Noise from an Electrical Motor (2013)

An induction motor and synchronous motor are applied as a source of drive for machines such as power plants, home appliances and cars. Recently, electrical efficiency have been improved and mechanical structures have become lighter and smaller. As a result of these trends, mechanical vibration and noise are increasing. Vibration and noise caused by electromagnetic force must be reduced to provide a comfortable environment. To satisfy these needs, a system to simulate vibration and noise precisely and effectively at the mechanical design stage is needed. Such a simulation system would reduce the time needed for experimentation and reduce the length of development periods and costs of production.
Preparation of Activated Carbon from Artichoke Stem by ZnCl2 Activation: Application in Nickel(II) Adsorption from Aqueous Solution (2014)

ABSTRACT: Activated carbon is one of the most important industrial products due to its versatile applications. In this work, efficient activated carbon was produced and utilized for adsorption of nickel from simulated wastewater under varying operational parameters. The raw material (Artichoke) has been chemically modified by zinc chloride (ZnCl2) to improve its surface reactivity and enhance its adsorption capacity. \nThe adsorbent was characterized by the FTIR analysis. The experimental data were analyzed by adsorption isotherms and kinetic models. Langmuir equation proved to be suitable to explain the adsorption process and the experimental results fit well with the pseudo-second-order model. \nThe performance of the prepared artichoke-based activated carbon (AAC) suggests it can be used as low coast or cheap adsorbent for the treatment of water and removal of heavy metal ions from industrial effluents. \nKeywords: Heavy metal ions, nickel, Activated carbon, Artichoke. \n…………………………………………………………………………………………………………………………\nÖZ: Aktif karbon önemli bir sanayi ürünü olarak çok çeşitli alanlarda kullanılmaktadır.

A comparative assessment of alignment angle of the knee by radiographic and physical examination methods (2005)

Knee alignment assessed clinically by goniometer or measured on a knee radiograph is correlated with the angle measured on the more cumbersome and costly full-limb radiograph. These alternative measures have the potential to provide useful information regarding the risk of progression of knee OA when a full-limb radiograph is not available.
Limbal epithelial stem cells of the cornea (2009)

The cornea on the front surface of the eye is our window to the world, hence maintenance of corneal tissue transparency is essential for vision. The integrity and functionality of the outermost corneal layer, the epithelium, plays a key role in refraction of light on to the retina at the back of the eye. Like other epithelia, the epithelium of the cornea is maintained by stem cells. This review will discuss what is currently known about the properties of these stem cells, the clinical consequences of stem cell failure and the potential for stem cell therapy in regeneration of the ocular surface.
cGMP transport by vesicles from human and mouse erythrocytes (2006)

cGMP secretion from cells can be mediated by ATP-binding cassette (ABC) transporters ABCC4, ABCC5, and ABCC11. Indirect evidence suggests that ABCC4 and ABCC5 contribute to cGMP transport by erythrocytes. We have re-investigated the issue using erythrocytes from wild-type and transporter knockout mice. Murine wild-type erythrocyte vesicles transported cGMP with an apparent Km that was 100-fold higher than their human counterparts, the apparent Vmax being similar. Whereas cGMP transport into human vesicles was efficiently inhibited by the ABCC4-specific substrate prostaglandin E1, cGMP transport into mouse vesicles was inhibited equally by Abcg2 and Abcc4 inhibitors/substrates. Similarly, cGMP transport into vesicles from Abcc4-/- and Abcg2-/- mice was 42% and 51% of that into wild-type mouse vesicles, respectively, whereas cGMP transport into vesicles from Abcc4(-/-)/Abcg2(-/-) mice was near background. The knockout mice were used to show that Abcg2-mediated cGMP transport occurred with lower affinity but higher Vmax than Abcc4-mediated transport. Involvement of Abcg2 in cGMP transport by Abcc4-/- erythrocyte vesicles was supported by higher transport at pH 5.5 than at pH 7.4, a characteristic of Abcg2-mediated transport. The relative contribution of ABCC4/Abcc4 and ABCG2/Abcg2 in cGMP transport was confirmed with a new inhibitor of ABCC4 transport, the protease inhibitor 4-(2-aminoethyl)benzenesulfonyl fluoride.
Effects of membrane interaction and aggregation of amyloid β-peptide on lipid mobility and membrane domain structure (2013)

Alzheimer's disease (AD) is the most prevalent age-dependent form of dementia, characterized by extracellular amyloid deposits comprising amyloid β-peptide (Aβ) in the cerebral cortex. Increasing evidence has indicated that ganglioside GM1 (GM1) in lipid rafts plays a pivotal role in amyloid deposition of Aβ and the related cytotoxicity in AD. Despite recent efforts to characterize Aβ-lipid interactions, the effect of Aβ aggregation on dynamic properties and organization of lipid membranes is poorly understood. In this study, we examined the aggregation of Aβ on supported lipid bilayers containing raft components (i.e., cholesterol, sphingomyelin, and GM1) and its effects on the membrane properties. We showed that the lateral fluidity of membranes was significantly affected by membrane binding and subsequent aggregation of Aβ. Microscopic observations of the membrane surfaces demonstrated an enhancement in phase separation of lipids as a result of interactions between Aβ and GM1 during induced aggregation of Aβ. The uptake of GM1 into Aβ aggregates and the attendant membrane damage were also observed under a microscope when the membrane-anchored aggregates were formed. On the basis of these observations, we propose that Aβ aggregates formed in the presence of lipid membranes have a latent ability to trigger the uptake of raft components accompanied by phase separation of lipids.
Context-Aware Communication for V2V Collision Avoidance Applications (2020)

The ultimate goal of Cooperative intelligent transportation systems (C-ITS) - zero fatality - necessitates the communication system be extremely intelligent, being able to make the best decision in selecting technologies, radio channels, communication protocols, and protocol parameters such that the road-safety application requirements are met. This work is interested in the framework of context-aware communication, which we believe a powerful solution to reach the challenging goal of C-ITS. In context-aware communications, C-ITS entities are aware of contexts, which can be application requirements, environmental condition, radio resources, and so on, and make intelligent decisions exploiting such contextual information. In this paper, we first introduce a context aware communication architecture, which consists of three main functional blocks: context acquisition, context reasoning, and system control. Targeting collision avoidance applications, we present a context-aware communication system, which establishes two types of contexts, one is application requirement and the other is resource availability. We then propose to express the application requirement by the minimum required packet delivery ratio, which can be derived from collision probability. Finally, we evaluate the performances of different Cooperative Awareness Service (CAS) schemes and compare them against the application requirement. The results show that periodic Cooperative Awareness Message (periodic-CAM) and reactive distributed congestion control (DCC) algorithms fail to meet the application requirement, while LIMERIC DCC meets the requirement for the evaluated scenario.
Controlling the Structural and Optical Properties of Ta3N5 Films through Nitridation Temperature and the Nature of the Ta Metal (2014)

The development of a reliable synthetic route to produce high performance Ta3N5 photoanodes has been complicated by the large number of synthetic parameters, notably nitridation conditions. A systematic study of nitridation from 850 °C–1000 °C reveals that, contrary to common knowledge, nitridation temperature has little effect on the quality of the Ta3N5 produced. Rather, it is the nature of the tantalum starting material and substrate that play a key role. Ta3N5 films synthesized by thermal oxidation and subsequent nitridation of Ta thin films on inert fused silica substrates exhibit identical structural and optical properties, regardless of preparation temperature. The optical spectra collected on these samples reveal clear, distinct features that give insight into the electronic band structure. Films grown in the same manner on Ta foils, however, reveal that textured Ta2N is formed at the Ta3N5/Ta interface even at low temperature, as shown by grazing incidence X-ray scattering. Ta3N5 on Ta foils is converted to bulk Ta5N6 at 1000 °C, and the possible mechanisms for these phase transitions are discussed.
Intravitreal bevacizumab as anti-vascular endothelial growth factor in the management of complications of proliferative diabetic retinopathy. (2013)

Vascular endothelial growth factor (VEGF) has been shown to be an endothelial cell-specific mitogen and an angiogenic inducer in a variety of in vitro and in vivo models. Furthermore, it has been demonstrated to increase retinal vessel permeability by increasing the phosphorylation of tight junction proteins. Recent work has found elevated levels of VEGF in ocular fluids of patients with proliferative diabetic retinopathy (PDR). Thus, it makes sense to consider anti-VEGF treatments in the management of PDR. The purpose of the current research is to determine if intravitreal bevacizumab as anti-VEGF is helpful in the management of complications of PDR.
Analysis of Monosaccharides as Per-O-Acetylated Aldononitrile (PAAN) Derivatives by Gas-Liquid Chromatography (GLC) (2021)

Gas chromatographic (GC) analysis of carbohydrates has been performed employing several types of derivatives. The trimethylsilyl (TMS) ethers of carbohydrates have been widely used in the past because of their ease of formation and their relatively high volatility. The increased volatility is particularly important for the analysis of oligosaccharides. TMS derivatives of carbohydrates have several disadvantages. Acetylated derivatives are generally employed for monosaccharides only, since derivatives of oligosaccharides are not sufficiently volatile for analysis by gas-liquid chromatography (GLC) with polar packings. The Per-O-Acetylated Aldononitrile (PAAN) derivatives have also been used by Varma and co-workers to identify arabinose in brain hyaluronic acid. PAAN derivatives have the presence of the nitrile to distinguish the (former) reducing end of the sugar in mass spectrometry (MS).

Vaccine-Induced Measles Virus-Specific T Cells Do Not Prevent Infection or Disease but Facilitate Subsequent Clearance of Viral RNA (2014)

Infection with wild-type measles virus (MeV) induces lifelong protection from reinfection, and parenteral delivery of the live attenuated measles vaccine (LAV) also provides protection from measles. The level of neutralizing antibody is a good indicator of protection, but the independent roles of MeV-specific antibody and T cells have not been identified. In this study, macaques immunized with LAV through a nebulizer and a mouthpiece developed MeV-specific T-cell responses but not neutralizing antibodies. Upon challenge with wild-type MeV, these animals developed rashes and viremias similar to those in naive animals but cleared viral RNA from blood 25 to 40 days faster. The nebulizer-immunized animals also had more robust MeV-specific CD4(+) and CD8(+) T-cell responses than the naive animals after challenge, characterized by a higher number and better durability of gamma interferon (IFN-γ)-producing cells. Induction of MeV-specific circulating CD4(+) and CD8(+) T cells capable of producing multiple cytokines correlated with clearance of viral RNA in the nebulizer-immunized macaques. These studies demonstrated that MeV-specific T-cell immunity alone did not prevent measles, but T-cell priming enhanced the magnitude, durability, and polyfunctionality of MeV-specific T cells after challenge infection and correlated with more rapid clearance of MeV RNA. IMPORTANCE The components of vaccine-induced immunity necessary for protection from infection and disease have not been clearly identified for most vaccines. Vaccine development usually focuses on induction of antibody, but T-cell-based vaccines are also under development. The live attenuated measles vaccine (LAV) given subcutaneously induces both T cells and neutralizing antibody and provides solid protection from infection. LAV delivered to the upper respiratory tract through a nebulizer and mouthpiece induced a T-cell response but no neutralizing antibody. These T-cell-primed macaques demonstrated no protection from rash or viremia when challenged with wild-type MeV, but viral RNA was cleared more rapidly than in unimmunized animals. Thus, T-cell immunity did not protect from infection or acute disease but facilitated virus clearance during recovery. These studies demonstrate the importance and independent roles of T cells and antibody in protection and recovery from measles.
The effect of porcine bile acids on methane production by rumen contents in vitro (1998)

Hindgut fermentation differs from rumen fermentation by a lower methane production and the presence of reductive acetogenesis. Bile acids which are lost into the lower digestive tract may have a promoting effect on reductive acetogenesis in the hindgut. In this experiment it was investigated if bile acids induce reductive acetogenesis in rumen fermentation in vitro. Rumen contents from a fistulated cow were incubated in vitro with ground hay and increasing amounts of porcine bile acids or bile acid salts. Bile acids inhibited methane production up to 70% of the control incubation. The concomitant increase in propionate production compensated for the lower methane production so that the 2H-recoveries were in a normal range between 79-92%. Therefore the occurrence of reductive acetogenesis could be excluded. It is concluded, that bile acids are a controlling factor in caecal methanogenesis.
Valerian extract modulates the GABAA-action on its receptors (2006)

Valerian act at the central GABA system which mediates inhibitory actions. A modulation of the GABA induced chloride channels conductance (IGABA) has been tested for different valerian extracts manufactured with either ethanol (C1), methanol (C2) or ethyl acetate (C3) to obtain extracts with different constituents, and in addition an ethyl acetate extract from C2 residue (C4) as well as the combination of C2 + C4 (C5). From anaesthetized female Xenopus laevis parts of the ovaries were removed. Follicel membranes from isolated oocytes were enzymatically digested with collagenase. Chloride channels conductance were studied 1 to 5 days after microinjection of approximately equimolar cRNA mixtures of α 1-, β 2- and γ 2S- subunits of the rat GABAA receptors in a ratio 1:1:10. Experiments were carried out at room temperature in bath solution containing (mM): 90 NaCl, 1 KCl, 1 MgCl2, 5 Hepes, 1CaCl2, adjusted to pH 7.4 with NaOH. Ionic influx was measured by means of the conventional two-microelectrode-voltage-clamp technique using a Turbo Tec 01C Amplifier (NPI Electronic, Germany). Voltage-recording and current-injecting microelectrodes were filled with 2 M KCl and had a resistance of 1–5 MΩ. GABA was solved freshly in bath solution every day immediately before the experiments. Valerian extracts (C1– C5) were solved in DMSO (20mg/mL) and the stock solution diluted to 50µg/mL and 100µg/mL, respectively. The extracts were either co-applied with GABA (EC3–10) or applied alone. Almost no stimulatory effects were observed if the extracts were applied alone. An enhancement of IGABA (EC3–10) of 134% and 123% respectively, could be observed for extracts C3 and C4. The following order of the activity was obtained: C4=C3 > C1=C5 > C2, indicating that the different active components by the solvents used are distinguishable solved.
Evaluating Rodent Management with Cambodian Rice Farmers (2002)

In discussing the principles of quantitative analysis in thin-layer media, we show that requirements for quantitative analysis are not satisfied when stained protein electrophoretic bands are scanned with a conventional rectangular-slit densitometer. We investigated a high-resolution densitometer based on a linear photodiode array as an alternative analytical tool, using stained electrophoretic bands of radio-labeled human serum albumin as a simplified model for results of serum protein electrophoresis. Identical protein bands scanned with both the high-resolution densitometer and a conventional densitometer were quantified with improved accuracy and precision by the new instrument. We also used the high-resolution densitometer to develop a computer model for performance characteristics of a rectangular-slit densitometer.
NTV-SV-PWM controlled three-level converter for ocean wave energy conversion (2015)

Ocean wave energy is one of the high potential renewable energy sources. Due to the recent progresses in the OWEC devices higher power extraction is possible which also brings the need of using multilevel converters to increase the voltage together with power. In this study, adaption of a sophisticated NTV-SV-PWM method to the multilevel converter is proposed, aiming to improve the energy extraction efficiency and the quality of the power transferred to the grid.

Link-Stability and Energy Aware Routing Protocol in Distributed Wireless Networks (2010)

Energy awareness for computation and protocol management is becoming a crucial factor in the design of protocols and algorithms. On the other hand, in order to support node mobility, scalable routing strategies have been designed and these protocols try to consider the path duration in order to respect some QoS constraints and to reduce the route discovery procedures. Often energy saving and path duration and stability can be two contrasting efforts and trying to satisfy both of them can be very difficult. In this paper, a novel routing strategy is proposed. This proposed approach tries to account for link stability and for minimum drain rate energy consumption. In order to verify the correctness of the proposed solution a biobjective optimization formulation has been designed and a novel routing protocol called Link-stAbility and Energy aware Routing protocols (LAER) is proposed. This novel routing scheme has been compared with other three protocols: PERRA, GPSR, and E-GPSR. The protocol performance has been evaluated in terms of Data Packet Delivery Ratio, Normalized Control Overhead, Link duration, Nodes lifetime, and Average energy consumption.
Studies on the mechanism of clinical tolerance in solar urticaria (1984)

Tolerance to artificial ultraviolet radiation (UVR) was induced in three patients with solar urticaria by administering graded whole body exposures to long-wave ultraviolet radiation (UV-A, 320-400 nm) in a phototherapy cabinet. Plasma histamine levels, mast cell ultrastructure and cutaneous responses to intradermally injected codeine and histamine were examined before and after the induction of tolerance. No evidence of serum complement activation could be demonstrated following exposure of serum samples to UVR in vitro. These studies suggest that the state of tolerance is due neither to mediator (histamine) depletion nor to a systemic effect induced by UV-A but may be due to an increase in the mast cell degranulation threshold.
Reconstruction of the extensor apparatus of the knee with the Leeds-Keio ligament (1994)

We describe a new method for the reconstruction of ruptures of the patellar ligament or the quadriceps tendon, using the flexible open-weave polyester Leeds-Keio prosthetic ligament. Of 25 operations performed since 1985, we were able to review 18 patients (19 knees) with a mean follow-up of 3.5 years (3 to 6.5). No patient had required immobilisation of the knee after operation and the average period to return to normal activities without a walking aid was 10.5 weeks. The average range of motion was 146 degrees, and four patients could squat fully in the Japanese style. There was an extension lag (< 10 degrees) in only four patients; eight patients had some patellar crepitus which was mildly painful in three. There were no cases of infection, persistent joint effusion or rerupture of the extensor apparatus.
