Cultured corneal epithelia for ocular surface disease. (1999)

1. Presumed corneal epithelial stem cells can be harvested safely from the limbus and expanded successfully in vitro. 2. Expanded corneal epithelial cell cultures can be grown onto various carriers, but currently denuded amniotic membrane seems to be the best carrier for ocular surface repair. 3. Expanded corneal epithelial cell transplants appear to resurface damaged ocular surfaces successfully, but cellular tracking and further confirmation are required. 4. Expanded allogeneic corneal epithelial cell transplants are technically possible and may represent alternative treatment modalities for selected ocular surface problems. 5. These techniques potentially offer a new method of restoring a normal ocular surface while minimizing the threat of damage or depletion to the contralateral or sibling limbal corneal epithelial stem cells. 6. The rabbit model was probably incomplete and should be interpreted with caution. The complete eradication of all corneal epithelial stem cells from any eye is difficult, making confirmation of such work challenging. 7. The results of the rabbit model suggest that allogeneic grafts may restore a nearly normal ocular epithelial surface to certain ocular surface injuries.
New Polymer Syntheses IV. Synthesis and Characterization of New Polyamides Containing Bis-Benzthiazolyl Sulphone Units in the Main Chain (1996)

Bis(2-aminobenzthiazolyl) sulphone (BABS) was used as a new starting material for preparing polyamides. These polyamides were prepared by reacting BABS with adipoyl, sebacoyl, isophthaloyl and terephthaloyl dichlorides, and also with 4,4′-azodibenzoyl chloride or 3,3′-azodibenzoyl chloride, utilizing the solution polycondensation technique at low temperature. In addition, the model compound was synthesized by condensing the BABS with benzoyl chloride. Characterization of the monomer, model compound and the polyamides was accomplished by 1 H NMR, IR and elemental analyses. The polyamides had reduced viscosities of 0.25–0.63 dI/g in DMF or DMSO at 25 °C. All the polymers dissolved readily at room temperature in polar aprotic solvents. The thermal stability of the polymers was evaluated by TGA and DSC measurements.
Inhibition of signal transducer and activator of transcription 3 expression by RNA interference suppresses invasion through inducing anoikis in human colon cancer cells (2008)

These results suggest that STAT3 siRNA can inhibit the invasion ability of colon cancer cells through inducing anoikis, which antiapoptotic genes survivin and Bcl-xL contribute to regulation of anoikis. These studies indicate STAT3 siRNA could be a useful therapeutic tool for the treatment of colon cancer.

Vibration tests utilization in the study of reliability of connections in microelectronics (2006)

Reliability of electronic devices is a crucial scope of interest of the electronic manufacturing industry. The reliability is connected with electrical, thermal and mechanical properties of investigated products. Electrical and thermal properties are investigated during the specified tests such as thermal shocks, temperature, and humidity cycles, dry oven storage. Mechanical properties are concerned of mounted components are mainly problem of the assembly industry. At the present electronic components are mounted to the PCB mostly by surface mount technology (SMT) or flip chip processes. The lead-solders are being presently replaced with lead-free solders or electrically conductive adhesives. It is caused by the European and Japanese restrictions. The restrictions forbid using lead in consumer electronic products because of its harmful influence on beings. The new solders and assembly technology force to the following investigations of reliability of joints. This paper contains information about information tests as accelerated tests commonly used to evaluate fatigue life of interconnections in electronic assembly. In the first part of the paper short review of accelerated tests is presented. Anand's model of the solder joint used in finite elements analysis (FEA) and Darveaux's crack initiation and growth model are also mentioned, The bases of FEA and DOE are beyond the scope of this paper. In the second part of the paper harmonic as well as random variation and two different constructions of shakers, their advantages, limitations and requirements are presented. Characterization of specimen and vibration setup is considered. At the end of the paper vibration test is proposed.
Infrared Study of the Lattice Vibrations in LiTa<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msub><mml:mrow><mml:mi mathvariant="normal">O</mml:mi></mml:mrow><mml:mrow><mml:mn>3</mml:mn></mml:mrow></mml:msub></mml:mrow></mml:math> (1970)

Polarized infrared reflectivity measurements have been made on single-crystal LiTa${\mathrm{O}}_{3}$ in the frequency range 20 - 10 000 ${\mathrm{cm}}^{\ensuremath{-}1}$ at 300 \ifmmode^\circ\else\textdegree\fi{}K. Kramers-Kronig and classical-oscillator dispersion-theory analyses of these data have yielded values for the frequency, strength, and linewidth of the infrared-active transverse optic modes and longitudinal optic modes. Analysis of the far-infrared interference spectrum yields values of 41 and 40 for the ordinary and extra-ordinary clamped dielectric constants, as well as values for their temperature dependence and dispersion. A calculation is made of the spontaneous polarization in LiTa${\mathrm{O}}_{3}$ and LiNb${\mathrm{O}}_{3}$ using the x-ray ion displacements.
Aspirin triggers antiinflammatory 15-epi-lipoxin A <sub>4</sub> and inhibits thromboxane in a randomized human trial (2004)

There is increasing evidence that aspirin initiates biosynthesis of novel antiinflammatory mediators by means of interactions between endothelial cells and leukocytes. These mediators are classified as aspirin-triggered 15-epi-lipoxins. Such compounds may account at least in part for aspirin's clinical benefits, which are distinct from the well appreciated action of aspirin as a platelet inhibitor. Here, we addressed whether aspirin-triggered 15-epilipoxinA4 (ATL) formation is aspirin-dependent in humans and its relationship to aspirin's antiplatelet activity. We conducted a randomized clinical trial among 128 healthy subjects allocated to placebo or to 81-, 325-, or 650-mg daily doses of aspirin for 8 weeks. Plasma thromboxane (TX)B2, an indicator of platelet reactivity, and ATL were assessed from blood collected at baseline and at 8 weeks. Plasma ATL levels significantly increased in the 81-mg aspirin group (0.25 +/- 0.63 ng/ml, P = 0.04), with borderline increases in the 325-mg group (0.16 +/- 0.71 ng/ml) and no apparent significant changes in the 650-mg group (0.01 +/- 0.75 ng/ml, P = 0.96). When ATL and TXB2 were compared, levels changed in a statistically significant and opposite direction (P < 0.01) for all three aspirin doses. These results demonstrated that low-dose aspirin (81 mg daily) initiates production of antiinflammatory ATL opposite to the inhibition of TX. Monitoring ATL may represent a simple clinical parameter to verify an individual's vascular leukocyte antiinflammatory response with low-dose aspirin treatment. These results also emphasize the importance of cell-cell interactions in the modulation of hemostatic, thrombotic, and inflammatory processes.
<title>Evaluation of output strategy with separated buffer in ATM switching system (quality service lines)</title> (1997)

Since ATM networks support many types of traffic generated by variety of applications, they must be able to guarantee QoS for these types of traffic. QoS control schemes should support the individual service classes that are available through the ATM networks. Since, in general, the quality of a VC is affected by other VCs in the same transmission path and in other service classes, traffic control should support multiple service classes. In this paper, we propose the mechanism for the buffer allocation and the cell scheduling algorithm with logical separation of a single buffer in the ATM switching system, and analyze the cell loss probability and the delay of each traffic (CBR/VBR/ABR) based on the weighted value and the dynamic cell service scheduling algorithm. The proposed switch system classifies composite traffics incoming to the switch, according to the characteristic of traffic, and then stores them in the logically separated buffers (quality service lines). And the proposed system adopts the round-robin service with weighted value in order to transmit cells in buffers through output port.
Abstract 15801: Mitochondria-Targeted Antioxidant Therapy Prevents Angiotensin II Mediated Connexin43 Remodeling and Sudden Arrhythmic Death (2011)

Introduction: Angiotensin II activation and associated elevation in ROS have been implicated in pathogenesis of arrhythmia. Nevertheless, commonly used antioxidants have been ineffective in clinical trials. We created a transgenic mouse model of cardiac restricted overexpression of ACE (ACE8/8). These mice show spontaneous VT/ VF, sudden cardiac death (SCD), and a reduction in Cx43 level, which impairs conduction and predisposes to arrhythmia. We sought to determine the role and the major source of ROS in angiotensin II mediated VT/ VF and Cx43 remodeling. Method: Wild type and ACE8/8 mice with and without two weeks of treatment with a NOS inhibitor (L-NIO, 25 mg/Kg IP injections daily), a mitochondria-targeted antioxidant (Mito-TEMPO, 0.7 mg/Kg IP injections daily), and a NADPH oxidase inhibitor (apocynin 80 mg/L in drinking water) were studied. Crossing ACE8/8 mice with a P67 dominant negative (P67DN) mouse was used to confirm the NADPH oxidase role. Western blotting to detect oxidized protein levels (OxyBlot), detection of superoxide production in mitochondria by confocal microscopy and flow cytometry using MitoSOX red, and immunohistochemistry staining for Cx43 were performed. EP study was performed by a 1.1F octapolar catheter and a burst pacing protocol. Results: Proteins were more oxidized, mitochondrial ROS levels were increased by 6 fold (P Conclusion: Mitochondria-targeted antioxidant prevents VT/VF/SCD and Cx43 remodeling in an angiotensin II activated state. This result suggests a central role for mitochondria oxidative stress in ROS-induced arrhythmia and that mitochondria-targeted antioxidants may be effective antiarrhythmic drugs.
Rice bran oil and hypocholesterolemia in rats (1986)

Rats fed rice bran oil at 10% level for a period of eight weeks showed significantly lower levels of total cholesterol, low density lipoprotein and very low density lipoprotein cholesterol, both on cholesterol-containing and cholesterol-free diets. High density lipoprotein cholesterol was increased but triglyceride showed a decrease that was not statistically significant. Liver cholesterol and liver triglycerides were also reduced. Fecal excretion of neutral sterols and bile acids was increased after ingestion of rice bran oil.

Accuracy of Luminance Maps Obtained from High Dynamic Range Images (2007)

High dynamic range images can be converted into luminance maps if the response curve of the camera is known. Previous results for a consumer grade CCD camera have shown luminance errors as a function of Munsell hue and value. New measurements with a digital SLR camera with a CMOS sensor find two problems. First, saturated hues, especially blue, blue green, and purple are still difficult to measure. Second, surfaces with low reflectance below Munsell value N4 can be significantly overestimated, especially in spherical images obtained from the photography of mirror spheres. Nevertheless, it appears that HDR imaging is a suitable tool for luminance measurement if the scene contains luminance reference values such as calibrated matte color checkers and gray cards, and if dark surfaces and saturated hues are excluded. Spherical HDR images obtained from mirror spheres capture nearly the entire environment, but resolution and decreased sensitivity for surfaces with very low reflectance are still problems.
Nonstructural Ice Control (1998)

Abstract : Nonstructural ice control measures are used for reducing the frequency and severity of ice jam damages that do not rely on the use of a structure placed in the river. This report is a comprehensive review of current nonstructural ice control methods in use. Both advance measures and emergency response methods are addressed. where possible, the effectiveness of these methods has been assessed, and cost of application has been tabulated. In terms of development, some of these are still in their infancy, while others are well advanced in terms of available guidance and field experience. Nonstructural methods can be used to extend the operating envelope of structural measures and can play a role in an ice control strategy that uses both structural and nonstructural components to provide the desired results. There is little guidance currently available to predict the reduction in ice jam potential due to application of any of these measures. Further work in this area should focus on developing governing relationships that relate ice and river properties and meteorological conditions to ice jam potential and severity.
Immunoglobulin and complement deposition in glomeruli of 756 subjects who had committed suicide or met with a violent death. (1993)

Ten cases had mesangial IgA together with morphological or clinical laboratory findings suggestive of renal disease. If all these are regarded as IgA glomerulonephritis, then its prevalence can be estimated at 1.3%. For IgM glomerulonephritis, a prevalence of 0.3% was deduced.
Aminotelechelics: A convenient synthesis and characterization of primary amino‐terminated telechelic poly(propylene glycol) and polyisobutylene (2003)

Abstract The synthesis of amino‐terminated telechelic poly(propylene glycol) and polyisobutylene from their corresponding dihydroxy‐terminated derivatives was studied. The synthesis of these aminotelechelics was achieved by the coupling of imidazolylformates with ethylenediamine. The structure of the resulting amino‐functionalized polymers was determined by 1 H NMR, 13 C NMR, and matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry. On the basis of the spectroscopic and spectrometric results, a complete conversion of dihydroxy termini into diamino end groups was observed; that is, the number‐average functionality was found to be 2. © 2003 Wiley Periodicals, Inc.

On direct photoisomerization of cyclo-octene, a trans : cis photostationary ratio of 49 : 51 was observed, which is anomalously high for a strained cycloalkene, whereas the trans : cis ratios on toluene photosensitization in the liquid and vapour phase were 5 : 95 and 13 : 87, respectively.
Synthesis of Pt<sub>3</sub>Y and Other Early–Late Intermetallic Nanoparticles by Way of a Molten Reducing Agent (2017)

Early-late intermetallic phases have garnered increased attention recently for their catalytic properties. To achieve the high surface areas needed for industrially relevant applications, these phases must be synthesized as nanoparticles in a scalable fashion. Herein, Pt<sub>3</sub>Y-targeted as a prototypical example of an early-late intermetallic-has been synthesized as nanoparticles approximately 5-20 nm in diameter via a solution process and characterized by XRD, TEM, EDS, and XPS. The key development is the use of a molten borohydride (MEt<sub>3</sub>BH, M = Na, K) as both the reducing agent and reaction medium. Readily available halide precursors of the two metals are used. Accordingly, no organic ligands are necessary, as the resulting halide salt byproduct prevents sintering, which further permits dispersion of the nanoscale intermetallic onto a support. The versatility of this approach was validated by the synthesis of other intermetallic phases such as Pt<sub>3</sub>Sc, Pt<sub>3</sub>Lu, Pt<sub>2</sub>Na, and Au<sub>2</sub>Y.
Maturation of the Sensed Electrogram Amplitude Over Time in a New Subcutaneous Implantable Loop Recorder (1997)

The cause of recurrent syncope may be difficult to determine if the diagnosis is not established from initial noninvasive and invasive testing. Eighteen patients with recurrent syncope and negative tilt table and electrophysiological testing underwent implantation of a left pectoral subcutaneous loop recorder. This device "freezes" the preceding 7.5 or 15 minute rhythm strip after magnet application after spontaneous syncope. Baseline and follow-up electrograms were routinely recorded, and patients were followed until syncope recurred. Three patients had syncope within 1 month of implantation and were excluded from this report. Implantation electrogram amplitude was 250 +/- 124 microV and increased to 291 +/- 114 microV at 2-3 months, and increased further to 353 +/- 167 microV at 4-6 months (P < 0.001, ANOVA). Syncope recurred in 14 of the 15 patients. An arrhythmic basis for syncope was established (n = 7) or excluded (n = 7) in every patient who had recurrent syncope. All syncopal episodes were associated with diagnostic sensed electrograms. The increase in sensed electrogram amplitude over time suggests a maturation of the device-tissue interface. These results support the long-term viability of this implantable monitoring technique.
Impact of mask line edge roughness and statistical noise on next generation mask making (2012)

As extreme ultraviolet lithography (EUVL) moves toward high volume manufacturing and pushes to increasingly smaller critical dimensions, achieving the stringent requirements for line edge roughness (LER) is increasingly challenging. For the 22 nm half-pitch node and beyond, the International Roadmap for Semiconductors requires less than 1.6 nm of line width roughness (LWR) on the wafer. The major contributor of this tight LWR is wafer resist LER and mask LER. However, in current ITRS, there is no guideline for mask LER. While significant progress has been made to reduce the resist of the LER on the wafer, it is not yet clear how much the mask LER should be improved for a 22 nm half-pitch node application. Additionally, there are various approaches to obtaining a smaller LER on the mask. It could be improved either by reducing well-known statistical noise or manipulating some process condition or material. Both approaches are effective in improving the LER, however, they shows a different result in mask CD uniformity itself. In this paper, in addition to setting the criteria of the mask LER, we will discuss how tight the mask LER is required to be and what kind of approach is desirable with regards to the LER and CD uniformity. Finally, an analysis of the LER and CD variation provides some insights into the impact of the next generation mask infrastructure.
Image and Texture Segmentation Using Local Spectral Histograms (2006)

We present a method for segmenting images consisting of texture and nontexture regions based on local spectral histograms. Defined as a vector consisting of marginal distributions of chosen filter responses, local spectral histograms provide a feature statistic for both types of regions. Using local spectral histograms of homogeneous regions, we decompose the segmentation process into three stages. The first is the initial classification stage, where probability models for homogeneous texture and nontexture regions are derived and an initial segmentation result is obtained by classifying local windows. In the second stage, we give an algorithm that iteratively updates the segmentation using the derived probability models. The third is the boundary localization stage, where region boundaries are localized by building refined probability models that are sensitive to spatial patterns in segmented regions. We present segmentation results on texture as well as nontexture images. Our comparison with other methods shows that the proposed method produces more accurate segmentation results.
Latent image formation: Nanoscale topography and calorimetric measurements in chemically amplified resists (1996)

The characterization of photoresists during the image formation process has traditionally relied on bulk methods during or after development. This article shows that it is not necessary to develop the photoresist in order to obtain significant information about the image formation process in x-ray, electron beam, and UV lithography. The characterization of the image formation process in chemically amplified photoresists prior to development is difficult due to their sensitivity to electrons used in scanning electron microscopy and the weak changes in dielectric constant needed for optical microscopy. The advent and development of the atomic force microscope (AFM) have allowed local surface measurements of exposure induced changed in photoresists with sub-μm scale resolution and negligible modification of the sample. A series of chemically amplified resists, positive and negative, have been studied with a variety of exposure radiation (electron beam, x-ray, and UV). The results discussed in this article focus on two of these resists: SAL 605 (−), and TOK 010 (+). Both positive and negative chemically amplified resists exhibit significant changes in topography and calorimetric properties during the image formation process. Interpretation of the resist topography in negative resists is given by a semi-empirical model that assumes Fickian diffusion of resist material during post-exposure bake (PEB) and verified with AFM data. The glass transition temperature, Tg, of wafer spun thin films of SAL 605 has been measured, prior to exposure, to be 75±3°C with an ellipsometric technique. The PEB temperature, 105°C, is much greater than the Tg of SAL 605, thereby providing some justification for our Fickian diffusion model. These results are preliminary until a chemical map can be done on the resist at sub-μm resolution, which at present time is not possible. The need for detecting intrinsic material property changes due to the image formation process motivates the exploration of calorimetric properties of the resist. Interpretation of the calorimetric data is still unclear. Both cases of positive and negative photoresists exhibit an increase of heat absorbed in the exposed regions. Photoacid ions produced by exposure to radiation may be considered responsible for such an increase.
