Card user awareness based on linear sub-space representation (2011)

Nowadays, “cards” are becoming part of our lives. To prevent the cards from being illegally used, card user authentication is indispensable. A common practice for user authentication is to use some secret information known or possessed by the true card holder. However, if the secret information is leaked, some malicious third party may still be able to use the card illegally. To solve the problem, this paper proposes a new authentication method based on linear sub-space representation. The basic idea is to hide the face image of the card holder into some other images, distribute the key information for restoring the face image into several places, and restore the face image when necessary. Compared with the methods we proposed earlier, the new method is more efficient, and is easier to implement.
Central Retinal Artery Perfusion following 0.1 ml Intravitreal Injection of Bevacizumab (2009)

Purpose: To study the pattern of perfusion of central retinal artery (CRA) after 0.1 ml intravitreal injection of bevacizumab to verify the need for any maneuver to decrease the intraocular pressure (IOP) including anterior chamber paracentesis (ACP) Methods: This is a prospective, interventional, noncomparative case series. Patients receiving intravitreal injection of bevacizumab for choroidal neovascularization (CNV) secondary to agerelated macular degeneration, diabetic macular edema and retinal veno-occlusive diseases were included in the study. Each eye received 0.1 ml intravitreal injection of bevacizumab and the status of perfusion of CRA and its pulsation was monitored by indirect ophthalmoscopy until cessation of visible pulsation. Main outcome measures were patency of CRA, its pulsation and time from injection to cessation of pulsation. Results: Seventy seven eyes of 70 patients were studied. At first ophthalmoscopy 30 seconds after injection, CRA was open in all cases with or without pulsation. CRA occlusion was not observed in any case. In 20 eyes (26%) CRA was patent without pulsation. In 57 eyes (74%) CRA pulsation was detected and this visible pulsation of CRA stopped within an average time of 167±99 seconds (range: 30-480 seconds). From 17 eyes which had significant vitreous reflux, only 6 eyes had CRA pulsation which stopped in a mean time of 80±36 seconds. There was a significant difference between pulsation duration in patients with and without vitreous reflux (Mann-Whitney U test, P=0.005). Absence of postinjection vitreous reflux was a risk factor for CRA pulsation after intravitreal injection of 0.1 ml of bevacizumab (relative risk: 2.41, 95% CI: 1.25-4.62). Conclusion: Considering the absence of CRA closure and the short time needed for the cessation of pulsation after intravitreal injection of 0.1 ml bevacizumab, no treatment including ACP is warranted before or after such injections in nonglaucomatous eyes. Indirect ophthalmoscopy is a noninvasive useful maneuver to ascertain patency of CRA after intravitreal injections.

A single rod multi-modality multi-interface level sensor using an AC current source (2008)

Crude oil separation is an important process in the oil industry. To make efficient use of the separators, it is important to know their internal behavior, and to measure the levels of multi-interfaces between different materials, such as gas-foam, foam-oil, oil-emulsion, emulsion-water and water-solids. A single-rod multi-modality multi-interface level sensor is presented, which has a current source, and electromagnetic modalities. Some key issues have been addressed, including the effect of salt content and temperature i.e. conductivity on the measurement.

Vaso-occlusion by sickle cells: evidence for selective trapping of dense red cells (1986)

We have characterized the type of red cells from sickle cell patients that were trapped in the course of sickle-cell vaso-occlusion. In addition, the perfusion conditions (arterial perfusion pressure [Pa] and oxygen tension [PO2]) leading to experimentally induced vaso- occlusion in the artificially perfused, innervated mesocecum microvascular preparation were determined. Microvascular obstruction was induced by decrease in Pa; the lower the Pa, the greater the peripheral resistance as well as the extent of obstruction. The cells involved in the obstruction were recovered by vasodilation (secondary to denervation) and increase in Pa. Densitometric analysis of density gradient-separated infused and trapped cells was supplemented with morphological analysis to ascertain the involvement of density classes as well as morphological types seen in oxy and deoxy sickle blood. The trapping phenomenon was sensitive to PO2. Percentage of densest gradient classes, ie, fraction 3 (F3; mainly dense unsicklable SS discocytes [USDs]) and fraction 4 (F4; irreversibly sickled cells [ISCs] and the densest discocytes), showed a significant increase in trapping when perfusion was switched from oxy to deoxy perfusate. Morphological analysis revealed that unsicklable SS discocytes are more effectively trapped when deoxygenated. The deoxygenation of infused cells did not further change the percentage of ISCs trapped, suggesting that ISCs are equally capable of sequestration in the oxy and the deoxy states. The venous effluent showed a selective and significant depletion of dense cells (F4) and ISC counts at all Pa. We conclude that the progressive obstruction of the microcirculation by sickle cells involves selective sequestration of the densest classes of cells and that this mechanism might explain their partial disappearance during painful sickle cell crisis.
Signal Processing of FM-CW SAR Using the Modified Frequency Scaling Algorithm (2008)

A modified Frequency Scaling algorithm is presented for FM-CW SAR signal processing. In FM-CW SAR,for the large PRI and the 100% duty cycle of the transmitted pulse,thestop and gomanner is no more valid. According to the signal processing characteristics of the FM-CW SAR,the problems such as the fast time range walk(FrRW) caused by the motion of the radar during the large PRI,and the range frequency spectrum alias caused by the direct utilization of the traditional Frequency Scaling algorithm,are dis- cussed deeply,the modified algorithm resolved the problems referred of before. The deduction and the simulation proved the algorithm is feasible and correct.

Renewable-surface sol–gel derived carbon ceramic electrode fabricated by [Ru(bpy)(tpy)Cl]PF<sub>6</sub>and its application as an amperometric sensor for sulfide and sulfur oxoanions (2002)

A highly sensitive and fast responding sensor for the determination of thiosulfate, sulfite, sulfide and dithionite is described. It consists of a chemically modified carbon ceramic composite electrode (CCE) containing [Ru(bpy)(tpy)Cl]PF6 complex that was constructed by the sol-gel technique. A reversible redox couple of Ru(II)/Ru(III) was observed as a solute in acetonitrile solution and as a component of carbon based conducting composite electrode. Electrochemical behavior and stability of modified CCE were investigated by cyclic voltametry, the apparent electron transfer rate constant (kappa(S)) and transfer coefficient (a) were determined by cyclic voltametry which were about 28 s(-1) and 0.43 respectively. Electrocatalytic oxidation of S(2-), SO3(2-), S2O4(2-) and S2O3(2-) were effective at the modified electrode at significantly reduced overpotentials and in the pH range 1-11. Optimum pH values for amperometric detection of thiosulfate, dithionite, sulfide and sulfite are 7, 9, 2 and 2. Under the optimized conditions the calibration curves are linear in the concentration ranges 1-500, 3-80, 2-90 and 1-100 microM for S2O3(2-), SO3(2-), S2- and S2O4(2-) determination. The detection limit (signal to noise is 3) and sensitivity are 0.5 and 12, 2.8 and 6, 1.6 and 8, and 0.65 microM and 80 nA microM(-1) for thiosulfate, sulfite, sulfide and dithionite detection. The modified carbon ceramic electrode doped with Ru-complex shows good reproducibility, a short response time (t < 2 s), remarkable long term stability (> 6 month) and especially good surface renewability by simple mechanical polishing (RSD for eight successive polishing is 2%). The advantages of this sulfur compound amperometric detector based on ruthenium doped CCE are high sensitivity, inherent stability at a broader pH range, excellent catalytic activity, less expense and simplicity of preparation in comparison with recently published papers. This sensor can be used as a chromatographic detector for analysis of sulfur derivatives.
Knock‐in mouse model of alternating hemiplegia of childhood: Behavioral and electrophysiologic characterization (2014)

Our model reproduces the major characteristics of human AHC, and indicates that ATP1α3 dysfunction results in abnormal short-term plasticity with increased excitability (potential mechanism for seizures) and a predisposition to more severe SD responses (potential mechanism for hemiplegias). This model of the human condition should help in understanding the molecular pathways underlying these phenotypes and may lead to identification of novel therapeutic strategies of ATP1α3 related disorders and seizures.

Biology of Opioid Peptides (1979)

Opioid peptides are endogenous or synthetic peptides, with a spectrum of pharmacological activity similar to that of morphine and other narcotic agonist drugs. The designation opioid peptide can be made if (a) it produces morphine-like, naloxone reversible effects in several in vitro bioassay sys­ tems such as the guinea pig ileum (1), the cat nictitating membrane (2), the mouse vas deferens (3), and the neuroblastoma X glioma tissue culture preparation (4), and (b) if the peptide competes at low concentrations with opiate ligands for binding at opiate receptor binding sites (5-7). An addi­ tional, although not essential, criterion might include the production of naloxone reversible analgesia. These criteria exclude substance P which does have analgesic activity (8, 9), fragments of adrenocorticotropic hor­ mone which have very weak opiate receptor binding activity (10), and the morphine-like factor identified on the basis of morphine antibody recog­ nition (11). At present only three endogenous opiate peptides have been identified that have any claim to a physiological function. These are leucine5-enkepha­ lin (12), methionine5-enkephalin (12), and ,a-endorphin (13-16). Other frag­ ments of ,B-lipotropin such as LPH 61-69, LPH 61-76, LPH 61-77, and LPH 61-87 have opioid peptide activity (17-19) but current evidence sug­ gests that these may be artifacts of extraction or degradation products of ,B-endorphin (20). Other unidentified opioid peptides undoubtedly exist (21-24), but in the absence of structural and chemical identification it is impossible to assess their significance or biological function. The term endorphin as a generic name for opioid peptides has little to recommend
Development of Self Emulsifying Formulations of Poorly Soluble Naproxen for Enhanced Drug Delivery (2016)

Fumonisins: human health, presence in foods and biomarkers (2014)

Fumonisins (FBs), fungal toxins mainly produced by Fusarium verticillioides and Fusarium proliferatum, contaminate maize and maize-based foods throughout the world. Mechanistic studies indicate that ceramide synthase, an enzyme involved in sphingolipid synthesis, is one cellular target for FBs toxicity, leading to an increase of the sphinganine–sphingosine ratio. This chapter gives an overview on the proposed mechanism for FBs mode of action, their biological effects in humans, interactions with other mycotoxins, and worldwide occurrence in foods. In addition, a perspective of the evaluation of dietary exposure to FBs will be presented, namely through the estimated daily intake approach and through the assessment of the two known biomarkers, FBs themselves, and the sphinganine–sphingosine ratio.
Passively aligned fiber-optic transmitter integrated into LTCC module (2002)

We studied the possibilities of LTCC (low temperature cofired ceramics) technology to fabricate fiber-pigtailed transmitter arrays using surface-emitting sources, such as VCSELs, equipped with vertical-mounted multimode fiber pigtails. The designed LTCC module can be mounted vertically on a printed-circuit-board (PCB), thus providing small, essentially one-dimensional PCB footprint.
Integrated poly-SiGe nanomechanical resonators for wireless sensor nodes (2004)

Wireless Sensor Nodes are basic building blocks for future ubiquitous networks. These nodes have to be able to gather and transmit information to their neighbors in complete autonomy. This means that with no battery, they rely on scavenging the energy necessary to operate directly from their environment, like conversion of solar or vibration based energy. This stringent requirement drastically limits the power budget of those devices to a level below 100μW. From the architecture prospective, work on reducing the complexity of the transceiver is mandatory, in order to reduce both size and power consumption. The simplest approach relies on the on/off modulation of a GHz range carrier frequency signal in a transmit channel, which is then directly selected and demodulated in the receiving path. For these particular functionalities, i.e. frequency generation and filtering, nano-mechanical resonators present a strong advantage of scalability that helps to integrate them into dense arrays directly on top of CMOS. This avoids package parasitic, allows for MEMS/circuitry co-design, and eventually leads to size shrinkage and power saving.
Biocompatibility of electroactive polymers in tissues (2000)

The biocompatibility of ethylene-vinyl acetate copolymer (EVAc), polyethylene (PE), and polyaniline (PANi) films in the emeraldine (EM), nigraniline (NA) and leucoemeraldine (LM) intrinsic oxidation states were assessed through subcutaneous implantation into male Sprague-Dawley rats beneath the dorsal skin, for a period ranging from 19 to 90 weeks. Histological examination, interstitial pressure measurement, and X-ray photoelectron spectroscopy (XPS) were employed to determine the biocompatibility of the polymers. The polymers did not provoke inflammatory responses in the subcutaneous tissues over the entire implantation period. Characteristics features associated with tissue–implant incompatibility were not evident near the implantation. Interstitial pressure was measured to evaluate the development of tissue. Low interstitial pressure readings on the region of implantation confirmed the biocompatibility of these polymer types. The surface composition of the electroactive aniline polymers before and after the implantation was characterized by XPS. © 2000 John Wiley & Sons, Inc. J Biomed Mater Res, 52, 467–478, 2000.
Millimeter-wave GaAs power FET with a pulse-doped InGaAs channel (1988)

Performance of a GaAs power MESFET has been improved significantly by incorporating a pulse-doped InGaAs layer in the GaAs n-channel. InGaAs provides electron transport properties superior to those of GaAs. The doping level of the GaAs layer can be very high, making it a very-high-transconductance device. Moreover, the conduction-band discontinuity at the heterointerface acts as a potential barrier for electron confinement; therefore, the power gain of the FET is significantly improved. The resulting device delivered a power density of 0.6 W/mm with 14% power-added efficiency and 3.5-dB gain at 60 GHz. At a gain of 5.1 dB, power density was 0.4 W/mm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Deactivation of fused silica capillary columns with phenylhydrosiloxanes (1985)

Abstract In this work, an investigation of new organosilicon hydride reagents with phenyl functional groups for deactivation and surface modification of fused silica capillary columns is described. Different reagents were tested for their ability to deactivate the fused silica surface, and actual critical surface tension measurements were made using the capillary rise method. The deactivation procedure required lower optimum temperatures than conventional methods. Deactivated capillaries and coated capillary columns were prepared and tested for reproducibility, efficiency, and surface inertness towards basic and acidic compounds at the low nanogram level.
Rabbit corneal endothelial cell surface glycoproteins. (1985)

Sialic acid residues of plasma membrane glycoproteins of rabbit corneal endothelial cells were radiolabeled by oxidation with sodium periodate and reduction with sodium borotritide. Surface-labeled glycoproteins were resolved by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. The major surface labeled glycoproteins were designated GP 1-8 in order of their increasing mobility on the gel (M.W. = 220K (GP-1), 200K (GP-2), 170K (GP-3), 135K (GP-4), 110K (GP-5), 95K (GP-6), 80K (GP-7), and 44K (GP-8). On the basis of the behavior of these glycoproteins on various carrier-bound lectins, preliminary information concerning their saccharide moieties was obtained. All 8 components bound to agarose-linked wheat germ agglutinin; GP 4-6 bound to concanavalin A and GP 6-7 bound to Ricinus communis agglutinin. No component bound to Bandeiraea simplicifolia I, Bandeiraea simplicifolia II, Ulex europeus or soybean agglutinin. These data suggest that in addition to the presence of sialic acid/N-acetylglucosamine residues in all the eight glycoproteins, oligosaccharides with terminal beta-galactose residues occur in GP-6 and GP-7 while mannose (glucose) residues occur in GP 4-6.
A Model System for Activation-Induced Alternative Splicing of CD45 Pre-mRNA in T Cells Implicates Protein Kinase C and Ras (2000)

Multiple isoforms of the protein tyrosine phosphatase CD45 are expressed on the surface of human T cells. Interestingly, the expression of these isoforms has been shown to vary significantly upon T-cell activation. In this report, we describe a novel cell line-based model system in which we can mimic the activation-induced alternative splicing of CD45 observed in primary T cells. Of the many proximal signaling events induced by T-cell stimulation, we show that activation of protein kinase C and activation of Ras are important for the switch toward the exclusion of CD45 variable exons, whereas events related to Ca(2+) flux are not. In addition, the ability of cycloheximide to block the activation-induced alternative splicing of CD45 suggests a requirement for de novo protein synthesis. We further demonstrate that sequences which have previously been implicated in the tissue-specific regulation of CD45 variable exons are likewise necessary and sufficient for activation-induced splicing. These results provide an initial understanding of the requirements for CD45 alternative splicing upon T-cell activation, and they confirm the importance of this novel cell line in facilitating a more detailed analysis of the activation-induced regulation of CD45 than has been previously possible.
Evidence that type I diabetes and thyrogastric autoimmunity have different genetic determinants. (1980)

The prevalences of autoimmune endocrine disease and relevant organ-specific autoantibodies were determined in 141 patients with type I (insulin-dependent) diabetes and their families. All available members of the families were genotyped for HLA. Islet-cell antibody was found in 10 (4%) out of 248 unaffected siblings, all of whom were genetically potential cases of diabetes. One developed classical symptoms six months later. In contrast, thyroid and gastric parietal-cell antibodies occurred independent of the HLA-linked susceptibility to diabetes. These results suggest that different genes control the production of these autoantibodies and the susceptibility to type I diabetes.
Default development of cloned human naive CD4 T cells into interleukin‐4‐ and interleukin‐5‐producing effector cells (1995)

It was recently demonstrated that naive human and mouse CD4 T cells release low but sufficient levels of interleukin (IL)-4 at priming to support their development into IL-4 producers. To determine whether this IL-4 is produced by a minor subset of cells, freshly isolated human naive CD4 T cells were directly cloned by limiting dilution in the absence of exogenous IL-4. More than 95% of neonatal and 60% of adult naive T cells seeded in single-cell cultures could be expanded upon stimulation with anti-CD3 mAb immobilized on CD32-B7.1 L cell transfectants in the presence of IL-2. All 171 clones derived from four neonates and two adults produced IL-4 and IL-5 at generally high levels. Like the allergen-specific human Th2 clones described in the literature, these T cell clones produced little or no interferon-gamma upon stimulation via their T cell receptor/CD3 complex, whereas they released high levels of this cytokine when activated with phorbol 12-myristate 13-acetate+ionomycin. Cells cloned and expanded in the presence of anti-IL4 + anti-IL-4R mAb produced much lower levels of IL-4 and IL-5. It is concluded that almost every single naive human CD4 T cell primed and expanded in the absence of exogenous IL-4 releases sufficient autocrine IL-4 to support its clonal expansion into high IL-4/IL-5 producers.

Myeloperoxidase/nitrite‐mediated lipid peroxidation of low‐density lipoprotein as modulated by flavonoids (2003)

In the presence of a H(2)O(2)-generating system, myeloperoxidase (MPO) caused conjugated diene formation in low-density lipoprotein (LDL), indicating lipid peroxidation which was dependent on nitrite but not on chloride. The oxidation of LDL was inhibited by micromolar concentrations of flavonoids such as (-)-epicatechin, quercetin, rutin, taxifolin and luteolin, presumably via scavenging of the MPO-derived NO(2) radical. The flavonoids served as substrates of MPO leading to products with distinct absorbance spectra. The MPO-catalyzed oxidation of flavonoids was accelerated in the presence of nitrite.
