M[sub 3](PO[sub 4])[sub 2]-Nanoparticle-Coated LiCoO[sub 2] vs LiCo[sub 0.96]M[sub 0.04]O[sub 2](M=Mg and Zn) on Electrochemical and Storage Characteristics (2008)

The electrochemical cycling and storage characteristics of LiCo0.96 M0.04 O2 and M3 (PO4)2 nanoparticle-coated LiCoO2 cathode materials (M=Zn and Mg) were compared at room temperature and 90°C between 3 and 4.5 V. The doped cathodes showed degraded electrochemical performance at room temperature compared to the uncoated cathode. The first discharge capacities of the uncoated and the doped cathodes were 186 and 175 mAhg, respectively. The doped cathodes showed 30 mAhg after 30 cycles, while the uncoated cathode showed 100 mAhg after 50 cycles at a 1 C rate. Mg3 (PO4)2 and Zn3 (PO4)2 -coated LiCoO2 showed discharge capacities of 179 and 187 mAhg, respectively, and hadsignificantly improved capacity retention, showing 133 and 153 mAhg, respectively, after 50 cycles. After storage at 90°C, in the electrolytes using 4.5 V charged electrodes, the doped cathodes showed both greatly decreased side reactions with the electrolytes and formation of Co3 O4 and CoO phases from Li and Co dissolution. However, the coated cathodes did not show either structural transformation into the Co3 O4 and CoO phases or side reactions with the electrolytes.
Two-color vibrational imaging of glucose metabolism using stimulated Raman scattering (2017)

A two-color vibrational imaging technique for simultaneously mapping glucose uptake and incorporation activity inside single living cells is reported. Heterogeneous patterns of glucose metabolism are directly visualized from the ratiometric two-color images for various cell types, cells undergoing epithelia-to-mesenchymal transitions and live mouse brain tissues. The two-color imaging of glucose metabolism here demonstrates the development of multi-functional vibrational probes for multicolor imaging of cellular metabolism.
Effect of Obstructive Cholestasis on Membrane Traffic and Domain–Specific Expression of Plasma Membrane Proteins in Rat Liver Parenchmal Cells (1994)

We investigated the effect of bile duct ligation and its release on membrane traffic and plasma membrane protein distribution in rat hepatocytes. Immunofluorescence studies with monoclonal antibodies against six domain-specific surface antigens revealed that bile duct ligation leads to an accumulation of pericanalicular vesicles containing canalicular antigens. All apical antigens could be demonstrated in the basolateral plasma membrane, whereas only one out of three basolateral antigens redistributed to the canalicular plasma membrane. After release of bile duct ligation, the accumulated pericanalicular vesicles disappeared within minutes, whereas the plasma membrane polarity was not restored within 1 hr. Monitoring secretion of polymeric IgA and horseradish peroxidase into bile demonstrated that bile duct ligation also inhibits the transcytotic vesicle pathway and severely impairs the function of tight junctions. In contrast, bile duct ligation appears not to affect the endoplasmic reticulum to basolateral membrane traffic as assessed by determination of newly synthesized albumin and transferrin in serum nor does it influence receptor mediated endocytosis at the basolateral plasma membrane.
Decidua produces a protein that inhibits choriogonadotrophin release from human trophoblasts. (1991)

To test the hypothesis that uterine decidua may modulate trophoblast function, trophoblasts and decidual cells were isolated from term placentas by enzymatic digestion and Percoll gradient centrifugation. Placental trophoblasts were cocultured with decidual cells and trophoblasts or JEG-3 choriocarcinoma cells were incubated with medium conditioned by decidual cells (DCM) for 72-96 h. In cocultures decidual cells inhibited choriogonadotropin (hCG) release from trophoblasts by 75% in comparison with controls (P less than 0.001). The DCM contained a factor that markedly inhibited hCG release from trophoblasts and JEG cells in vitro compared with controls. The inhibitory effect of the factor on hCG release was dose dependent, and could be eliminated by boiling the DCM for 30 min or proteolytic enzyme treatment. Ultrafiltration and Sephadex G-50 fractionation of the DCM indicated that the apparent molecular mass was 7,000-10,000 D. DCM also inhibited the stimulatory effect of exogenous cAMP on hCG secretion by JEG-3 cells, suggesting that DCM may interfere with activation of the cAMP-dependent protein kinases or transcription of hCG genes. These results suggest that the release of trophoblast hCG is under local paracrine control, regulated in part by a protein released by decidual cells.

Biofilm formation in <i>Desulfovibrio vulgaris</i> Hildenborough is dependent upon protein filaments (2007)

Desulfovibrio vulgaris Hildenborough is a Gram-negative sulfate-reducing bacterium (SRB), and the physiology of SRBs can impact many anaerobic environments including radionuclide waste sites, oil reservoirs and metal pipelines. In an attempt to understand D. vulgaris as a population that can adhere to surfaces, D. vulgaris cultures were grown in a defined medium and analysed for carbohydrate production, motility and biofilm formation. Desulfovibrio vulgaris wild-type cells had increasing amounts of carbohydrate into stationary phase and approximately half of the carbohydrate remained internal. In comparison, a mutant that lacked the 200 kb megaplasmid, strain DeltaMP, produced less carbohydrate and the majority of carbohydrate remained internal of the cell proper. To assess the possibility of carbohydrate re-allocation, biofilm formation was investigated. Wild-type cells produced approximately threefold more biofilm on glass slides compared with DeltaMP; however, wild-type biofilm did not contain significant levels of exopolysaccharide. In addition, stains specific for extracellular carbohydrate did not reveal polysaccharide material within the biofilm. Desulfovibrio vulgaris wild-type biofilms contained long filaments as observed with scanning electron microscopy (SEM), and the biofilm-deficient DeltaMP strain was also deficient in motility. Biofilms grown directly on silica oxide transmission electron microscopy (TEM) grids did not contain significant levels of an exopolysaccharide matrix when viewed with TEM and SEM, and samples stained with ammonium molybdate also showed long filaments that resembled flagella. Biofilms subjected to protease treatments were degraded, and different proteases that were added at the time of inoculation inhibited biofilm formation. The data indicated that D. vulgaris did not produce an extensive exopolysaccharide matrix, used protein filaments to form biofilm between cells and silica oxide surfaces, and the filaments appeared to be flagella. It is likely that D. vulgaris used flagella for more than a means of locomotion to a surface, but also used flagella, or modified flagella, to establish and/or maintain biofilm structure.
[Reasonable lymph node dissection in radical gastrectomy for gastric cancer: introduction of computer information system and lymphography technique by India-ink]. (1989)

A computer information system was developed and clinically used in National Cancer Center Tokyo in 1983. Seven data of an individual patient are preoperatively input in the system: sex, age, location, macroscopic type, maximal diameter, depth of invasion, and histological type of biopsy. After the data-analysis of 3,785 patients, the computer outputs three data; expected five year survival rate, each metastatic rate of 16 regional lymph nodes, and types of recurrence. Plan of lymph node dissection can reasonably be decided by this report. 0.5ml of India-ink (CH-40) is injected in the perigastric lymph nodes, and it stains all lymphatic channels from the injection points in black. Using the technique, systematic dissection can be performed easily and completely. After the introduction of these systems, five year survival rate was improved from 90.0% to 95.5% in Stage I, from 76.0% to 81.6% in Stage II, from 51.1% to 56.8% in Stage III, and from 12.9% to 16.6% in Stage IV.
Radiation modulation of MicroRNA in prostate cancer cell lines (2008)

miR-521 modulates the expression levels of DNA repair protein, CSA and plays an important role, in the radio-sensitivity of prostate cancer cell lines. Thus miR-521 can be a potential target for enhancing the effect of radiation treatment on prostate cancer cells.
Origin of the increased resistivity in epitaxial<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msub><mml:mrow><mml:mi mathvariant="normal">Fe</mml:mi></mml:mrow><mml:mrow><mml:mn>3</mml:mn></mml:mrow></mml:msub></mml:mrow><mml:mrow><mml:msub><mml:mrow><mml:mi mathvariant="normal">O</mml:mi></mml:mrow><mml:mrow><mml:mn>4</mml:mn></mml:mrow></mml:msub></mml:mrow></mml:math>films (2002)

We report resistivity measurements on epitaxial ${\mathrm{Fe}}_{3}{\mathrm{O}}_{4}$ films between 3 and 100 nm thickness grown on polished MgO substrates. The resistivity of the films is larger than the bulk resistivity, and is increasing with decreasing film thickness. This can be explained by the significant decrease of antiphase domain size with decreasing film thickness, as observed by transmission electron microscopy. The domain size decreases from 40 nm for 100-nm-thick films, to 5 nm for 3-nm-thick films. The effective conductivity has been modeled as a function of the bulk and boundary conductivities using the effective medium approximation. It is suggested that the absence of the Verwey transition in the thinnest films is also related to the very small domain size, which inhibits long-range order.
Enhanced high-frequency absorption of anisotropic Fe3O4/graphene nanocomposites (2016)

Anisotropic Fe3O4 nanoparticle and a series of its graphene composites have been successfully prepared as high-frequency absorbers. The crystal structure, morphology and magnetic property of the samples were detailed characterized through X-ray diffractometer (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). The high-frequency absorbing performance of the composites is evaluated within 2.0-18.0 GHz. Combining reduced graphene oxide (RGO) to Fe3O4 helps to adjust the permittivity and permeability of the composite, balance the dielectric loss and magnetic loss, consequently improve the absorbing performance in view of the impedance matching characteristic. The optimal reflection loss of the pure Fe3O4 sample reaches -38.1 dB with a thickness of 1.7 mm, and it increases to -65.1 dB for the sample grafted with 3 wt.% RGO. The addition of proper content of RGO both improves the reflection loss and expands the absorbing bandwidth. This work not only opens a new method and an idea for tuning the electromagnetic properties and enhancing the capacity of high-efficient absorbers, but also broadens the application of such kinds of lightweight absorbing materials frameworks.
Synthesis of Long-Chain Branched Comp-Structured Polyethylene from Ethylene by Tandem Action of Two Single-Site Catalysts (2003)

The synthesis of long-chain branched polyethylene by copolymerization of ethylene with higher α-olefins has its limitations due to commercial availabilities of pure α-olefins above carbon lengths of C30. Soga1 and Bazan2 have shown the possibility of inserting side chains up to a length of 60 carbons into a growing polyethylene backbone. The details of combining [Me2C(Cp)2]ZrCl2 (1) and [Me2Si(NtBu)(Me4Cp)]TiCl2 (2) to obtain long-chain branched polyethylene with branch lengths up to 350 carbons as well as the copolymerization profile and purification of the product throughout the Kumagawa extraction are discussed here. Compound 1 was used in a first oligomerization step to yield a macro-comonomer. Three different methods involving conventional copolymerization, tandem polymerization, and simultaneous entry of the catalysts were examined using 2 and MAO as cocatalyst to copolymerize different macro-comonomers with ethylene.
Corrosion Rate of n‐ and p‐Silicon Substrates in HF, HF + HCl, and  HF  +  NH 4 F  Aqueous Solutions (1999)

A research program was initiated in order to investigate the electrochemical corrosion of n‐ and p‐type silicon substrates in 0.25 M dilute HF solutions, and the influence of fluoride ions or proton additives. All experiments were conducted in both the dark and under constant light flux, with solutions thoroughly degassed by high purity argon bubbling. Polarization resistance measurements near an open‐circuit potential lead to the value of the corrosion current, while scanning the potential in the range of anodic and cathodic reactions permitted evaluation of the kinetics of charge transfer as a function of the majority carriers density in the semiconductor and the ionic composition of the solution. The influence of these parameters on the surface roughness of the silicon samples was also examined by ex situ atomic force microscopy profile measurements. © 1999 The Electrochemical Society.

Self similar progressive image coding scheme for multimedia packet switching communications (2002)

Connectionless services provided by best effort networks, such as SMDS and CBDS, are emerging in support of multicast real time communication over a global environment. A major role in the development of these services will be played by voice and video coding. The paper presents a novel coding approach for still images that combines a fractal approach with wavelet transform and multiresolution decomposition. A progressive coding is achieved by finding self-similarities between different scale bands of the wavelet pyramid. This coding technique has been successfully adopted over a regional wide IP environment where some users were connected by dial-up lines, several by N-ISDN and others through a LAN to LAN interconnection service provided by a regional DQDB MAN.
The Tumor Suppressor UCHL1 Forms a Complex with p53/MDM2/ARF to Promote p53 Signaling and Is Frequently Silenced in Nasopharyngeal Carcinoma (2010)

These results indicate that UCHL1 could deubiquitinate p53 and p14(ARF) and ubiquitinate MDM2 for p53 stabilization to promote p53 signaling, thus involved in nasopharyngeal carcinoma pathogenesis, whereas it is frequently silenced in this tumor.
Pigment epithelium‐derived factor (PEDF) is an endogenous antiinflammatory factor (2005)

Pigment epithelium-derived factor (PEDF) is a potent angiogenic inhibitor. Reduced PEDF levels are associated with diabetic retinopathy. However, the mechanism for the protective effects of PEDF against diabetic retinopathy (DR) is presently unclear. As inflammation plays a role in DR, the present study determined the effect of PEDF on inflammation. Western blot analysis and ELISA demonstrated that retinal and plasma PEDF levels were drastically decreased in rats with endotoxin-induced uveitis (EIU), which suggests that PEDF is a negative acute-phase protein. Intravitreal injection of PEDF significantly reduced vascular hyper-permeability in rat models of diabetes and oxygen-induced retinopathy, correlating with the decreased levels of retinal inflammatory factors, including VEGF, VEGF receptor-2, MCP-1, TNF-alpha, and ICAM-1. In cultured retinal capillary endothelial cells, PEDF significantly decreased TNF-alpha and ICAM-1 expression under hypoxia. Moreover, down-regulation of PEDF expression by siRNA resulted in significantly increases of VEGF and TNF-alpha secretion in retinal Müller cells. These findings suggest that PEDF is a novel endogenous anti-inflammatory factor in the eye. The decrease of ocular PEDF levels may contribute to inflammation and vascular leakage in DR.

Inter-cell coordination with inhomogeneous traffic distribution (2006)

We study the optimal division of cells into different service areas served under different coordinated transmission modes, i.e. combinations of base stations simultaneously transmitting, in order to avoid the adverse effect of inter-cell interference and to maximize the system capacity. We focus on the general case where the traffic load is inhomogeneous and give a complete characterization of the optimum for two-cell and three-cell systems in terms of a set of necessary conditions. An example of a three-cell system with a traffic load having a gradient in an arbitrary direction is numerically worked out.
The Approximation of One Matrix by Another of Lower Rank (1936)

The mathematical problem of approximating one matrix by another of lower rank is closely related to the fundamental postulate of factor-theory. When formulated as a least-squares problem, the normal equations cannot be immediately written down, since the elements of the approximate matrix are not independent of one another. The solution of the problem is simplified by first expressing the matrices in a canonic form. It is found that the problem always has a solution which is usually unique. Several conclusions can be drawn from the form of this solution. A hypothetical interpretation of the canonic components of a score matrix is discussed.
Bioactivity of polyurethane-based scaffolds coated with Bioglass® (2007)

Polyurethane (PUR) and polyurethane/poly(d, l-lactide) acid (PUR/PDLLA) based scaffolds coated with Bioglass particles for application in bone tissue engineering were fabricated. The slurry-dipping method was used for coating preparation. The homogeneous structure of the Bioglass coatings on the surface of the PUR and PUR/PDLLA foams indicated a good adhesion of the bioactive glass particles to polyurethane without any additional surface treatment. In vitro studies in simulated body fluid (SBF) were performed to study the influence of Bioglass coating on biodegrability and bioactivity of PUR-based scaffolds. The surface of Bioglass-coated samples was covered by a layer of carbonate-containing apatite after 7 days of immersion in SBF, while in uncoated polymer samples apatite crystals were not detected even after 21 days of immersion in SBF. The apatite layer was characterized by scanning electron microscopy (SEM), EDS analysis and attenuated total reflectance-Fourier transform infrared spectrometry (FTIR-ATR). Weight loss measurements showed that the in vitro degradation rate of the composite scaffolds in SBF was higher in comparison to uncoated polyurethane samples. PUR and PUR/PDLLA foams with Bioglass coating have potential to be used as bioactive, biodegradable scaffolds in bone tissue engineering.
Glucagon levels and metabolic effects in fasting man (1970)

The role of glucagon in the metabolic adaptation to prolonged fasting in man has been examined. Plasma immunoreactive glucagon was determined during 6-wk fasts and during infusion of exogenous glucagon using an assay which minimized nonpancreatic immunoreactivity. Plasma glucagon concentrations rose twofold to a peak on the 3rd day of fasting and then declined thereafter to a level maintained at or above postabsorptive. Insulin concentration declined to a plateau by the 3rd day. Thus a persisting altered relationship of glucagon and insulin concentrations characterized the fasted state. A synergism of low insulin and relative or absolute elevation of glucagon levels is viewed as a hormonal mechanism controlling the rate of hepatic substrate extraction for gluconeogenesis. Glucagon was infused systemically into 4-6 wk fasted subjects at three dose levels. A marked sensitivity of individual plasma free amino acids to the induced elevations of plasma glucagon within the physiologic range was demonstrated. At higher concentrations, equivalent to those present in the portal vein, stimulation of hepatic gluconeogenesis occurred, and the effects on glucose, insulin, and growth hormone levels and on ketone metabolism were induced.
A 1.3-µm 35-km fiber-optic microwave multicarrier transmission system for satellite earth stations (1987)

A field experiment that transmits a full bandwidth of C-band satellite downlink signals over 35 km of 1.3-μm single-mode fiber was demonstrated. The major requirements of this analog fiber-optic link for video transmission, including system linearity and carrier-to-noise ratio, were experimentally characterized. Assessment of the system performance was based on measurement of video signal quality. A complete system analysis is given and the results agree well with the measured data.
A novel spatial clustering algorithm based on Delaunay triangulation (2008)

Exploratory data analysis is increasingly more necessary as larger spatial data is managed in electro-magnetic media. Spatial clustering is one of the very important spatial data mining techniques. So far, a lot of spatial clustering algorithms have been proposed. In this paper we propose a robust spatial clustering algorithm named SCABDT (Spatial Clustering Algorithm Based on Delaunay Triangulation). SCABDT demonstrates important advantages over the previous works. First, it discovers even arbitrary shape of cluster distribution. Second, in order to execute SCABDT, we do not need to know any priori nature of distribution. Third, like DBSCAN, Experiments show that SCABDT does not require so much CPU processing time. Finally it handles efficiently outliers.
