Posteriorly Dislocated Capsular Tension Ring (2005)

A 69-year-old man who had pseudoexfoliation and significant nuclear cataract underwent cataract surgery in his right eye. At the beginning of the phacoemulsification, inferior zonulolysis was observed and a capsular tension ring was implanted. Anterior vitrectomy was also performed because of vitreous in the anterior chamber at the end of surgery. A tear in the posterior capsule could not be identified. Three days after surgery, the capsular tension ring was observed partially in the anterior vitreous. A 3-port pars plana vitrectomy was performed and the ring was removed. Three weeks later, the eye developed retinal detachment and was successfully repaired. Retinal complications can develop if the capsular tension ring moves into the vitreous.

Performance evaluation for blind methods of noise characteristic estimation for TerraSAR-X images (2011)

Estimation of noise characteristics is used in various image processing tasks such as edge detection, filtering, reconstruction, compression and segmentation, etc. It is very desirable to have as accurate as possible estimated noise characteristics which influence the quality of further processing. This paper deals with evaluation of accuracy of earlier proposed methods for blind estimation of speckle characteristics. Evaluation is done for TerraSAR-X single-look amplitude images. It is shown that the obtained estimates depend upon image complexity. Besides, parameters of any estimation method influence accuracy (bias) as well. Finally, spatial correlation of noise is yet another factor affecting the obtained estimates. As it is demonstrated, blind estimation in aggregate allows to obtain the estimates of speckle variance with relative error up to 20%, which is appropriate for practical needs. Besides, if speckle variance is estimated, it becomes possible to get accurate estimates of noise spatial correlation in DCT domain. Such estimates can be used in e.g. DCT-based filtering of SAR images.
Radio channel characterization of intra-body propagation under frequency dispersive perspective (2014)

In this paper we consider the analysis of the Brillouin precursor formation to understand the impairments undergone by ultra wideband waveforms propagating through naturally dispersive media as human tissues. By means of a frequency-domain method based on considering the frequency response of the medium under study, the effect of these media on the evolution of an input signal can be seen as a frequency filtering. The simulations were performed at a centre frequency of 6.5GHz and for a signal bandwidth of 3GHz. The experienced impairments are assessed in terms of the degradation experienced by the main functions that model the human body radio channel: power delay profile and frequency cross-correlation function (FCF). For them we analysed the effect of the dispersive propagation in terms of parameters used for information retrieval: peak amplitude decay, CCF secondary sidelobe level and multipath detectability. body radio propagation. We also review the definition of the parameters adopted to quantify the electromagnetic absorption inside biological tissue under the dispersive perspective.
In Situ Processing and High‐Temperature Properties of Ti 3 Si(Al)C 2 /SiC Composites (2006)

Ti 3 SiC 2 has many salient properties including low density, high strength and modulus, damage tolerance at room temperature, good machinablity, and being resistant to thermal shock and oxidation below 1100°C. However, the low hardness and poor oxidation resistance above 1100°C limit the application of this material. The poor oxidation resistance at temperatures above 1100°C was because of the absence of protective layer in the scale and the presence of TiC impurity phase. TiC impurity could be eliminated by adding a small amount of Al to form Ti 3 Si(Al)C 2 solid solutions. Although the high‐temperature oxidation resistance was significantly improved for the Ti 3 Si(Al)C 2 solid solutions, the strength at high temperatures was lost. One important way to enhance the high‐temperature strength is to incorporate hard ceramic particles like SiC. In this article, we describe the in situ synthesis and simultaneous densification of Ti 3 Si(Al)C 2 /SiC composites using Ti, Si, Al, and graphite powders as the initial materials. The effect of SiC content on high‐temperature mechanical properties and oxidation resistance were investigated. The mechanisms for the improved high‐temperature properties are discussed.
Exploration of mid-ocean ridges with a frequency-domain electromagnetic system (1994)

Electromagnetic-survey methods using controlled sources have been applied to ocean floor and mid-ocean-ridge surveys and have shed new light on the distribution of fluids within these structures. The present state of knowledge of the electrical nature of oceanic crust is reviewed and some alternative mid-ocean-ridge electromagnetic surveys are simulated using a numerical-modelling algorithm to see what further information they could provide. This simulation considers the response of both large-scale crustal targets such as magma bodies and zones of hydrothermal circulation, and also the effect of near-surface heterogeneity that may spatially alias the data. The magnitude of this heterogeneity is estimated and it is shown that it could be large enough to prevent useful structural constraints being obtained. If the effect spatial aliasing was negligible, or could be removed, a trans-ridge experiment could delinate zones of partial melting and hydrothermal circulation within the oceanic crust.
Ionized Serum Magnesium Levels in Umbilical Cord Blood of Normal Pregnant Women at Delivery: Relationship to Calcium, Demographics, and Birthweight (1993)

Using a novel ion-selective electrode for ionized Mg (IMg2+), we sought to: (1) determine levels and fractions of IMg2+ in umbilical vessels of normal pregnant women: (2) determine their relationships with ionized calcium (ICa2+) levels: (3) determine whether any demographic or clinical parameters affect these levels of divalent cations: and (4) compare levels of IMg2+, total Mg, percent IMg2+, and ICa2+ with sera of normal pregnant and nonpregnant women. We obtained umbilical arterial and venous serum from 38 normal subjects and venous samples from 26 normal pregnant women and 42 nonpregnant women. The mean umbilical venous IMg2+ level (0.51 +/- 0.01 mmol/liter) was significantly greater than the umbilical arterial level (0.48 +/- 0.01 mmol/liter, p < 0.05), and the latter was similar to maternal venous levels (0.48 +/- 0.01 mmol/liter). The maternal venous mean value is 20% less than that found (0.60 +/- 0.005 mmol/liter) in peripheral serum of nonpregnant women. The ionized fractions were significantly (p < 0.01) higher in the umbilical veins than umbilical arteries, and the percent IMg2+ fractions were similar in umbilical arteries and maternal venous blood. IMg2+ levels were lower in multiparous patients and those who received epidural analgesia and higher in patients who had operative vaginal delivery and in Asians. Ionized fractions of Mg in umbilical veins were higher in large for gestational age infants. Our findings provide evidence of a Mg deficiency in pregnancy and suggest that measurement of IMg2+ may have clinical value for diagnosis and therapy of such deficiency.(ABSTRACT TRUNCATED AT 250 WORDS)
Clinical significance of serum high‐molecular‐mass alkaline phosphatase, alkaline phosphatase–lipoprotein‐X complex, and intestinal variant alkaline phosphatase (1994)

This paper is a study to identify the clinical significance of high-molecular-mass alkaline phosphatase (ALP:E:C..3.1.3.1.), ALP-lipoprotein-X complex (LP-X) and intestinal variant ALP. We used cellulose acetate and agarose gels and techniques including wheat germ lectin, cetavlon-diethyl ether, thermostatability, neuraminidase and L-phenylalanine to improve the electrophoretic separation of the alkaline phosphatase isoenzymes. Patients' serum samples were electrophoresed from a diverse group of individuals ill with cholestasis, neoplastic disease metastatic to the liver, hepatocellular carcinoma, cirrhosis, diabetes mellitus, and chronic renal disease. Agarose gels provided better separation of ALP isoenzymes than cellulose acetate gels. The results also indicated that high-molecular mass ALP is present in patient's serum in conditions associated with cholestasis especially caused by hepatic malignancy. High-molecular mass ALP was frequently found to co-exist with the liver isoenzyme and LP-XALP complex. The intestinal variant was identified in patients with malignancy, cirrhosis, chronic renal disease and diabetes mellitus. Intestinal ALP coexisted concomitantly with a variant intestinal ALP. Intestinal variant ALP is most likely composed of intestinal ALP attached to a cellular membrane-binding domain, or may be an artifact produced by neuraminidase incubation.
On the Synthetic Utility of Thermally Generated Imines: The Retro-Ene Imino Diels-Alder Reaction (1982)

Long-term Effects of Off-Pump Coronary Bypass versus Conventional Coronary Bypass Grafting on Renal Function (2016)

Acute kidney injury is a risk factor for long-term renal dysfunction after either bypass method and was not greater after cCABG compared with OPCAB. Patients undergoing OPCAB did not experience greater decrease in long-term kidney function despite having worse baseline kidney function.
Hysterosalpingography: A Reemerging Study (2006)

Hysterosalpingography (HSG) has become a commonly performed examination due to recent advances and improvements in, as well as the increasing popularity of, reproductive medicine. HSG plays an important role in the evaluation of abnormalities related to the uterus and fallopian tubes. Uterine abnormalities that can be detected at HSG include congenital anomalies, polyps, leiomyomas, surgical changes, synechiae, and adenomyosis. Tubal abnormalities that can be detected include tubal occlusion, salpingitis isthmica nodosum, polyps, hydrosalpinx, and peritubal adhesions. Some complications can occur with HSG-most notably, bleeding and infection-and awareness of the possible complications of HSG is essential. Nevertheless, HSG remains a valuable tool in the evaluation of the uterus and fallopian tubes. Radiologists should become familiar with HSG technique and the interpretation of HSG images.

Período crítico de competencia del polocote (Helianthus annuus L.)en sorgo para grano (2005)

El polocote (Helianthus annuus L.), es la mala hierba más común y que más problemas origina en el sorgo para grano (Sorghum bicolor L. Moench) en el norte de Tamaulipas. El polocote es una maleza invernal en esta región y sus más altas poblaciones coinciden con la emergencia y primeras etapas de desarrollo del sorgo, que es afectado severamente por esta maleza altamente competitiva. En esta investigación se condujeron experimentos de campo en los años 2001 a 2003 para determinar el período crítico de competencia del polocote con el sorgo. De acuerdo con los modelos de regresión no-lineal ajustados, la competencia de polocote por cuatro semanas causó reducciones del rendimiento de sorgo de 20, 60 y 26% en 2001, 2002 y 2003. Los daños en 2002 fueron mayores debido a la escasa precipitación ocurrida en las primeras etapas de desarrollo del sorgo. Se determinó que el período crítico de competencia del polocote en sorgo, para evitar pérdidas mayores a 5% del rendimiento, es de 6.5 semanas después de la emergencia del cultivo.
Effect of Stem Cell Activation, Culture Media of Manipulated Embryos, and Site of Embryo Transfer in the Production of F0 Embryonic Stem Cell Mice1 (2009)

Recently, F0 embryonic stem (ES) cell mice have been produced by injection of ES cells into eight-cell embryos using either laser- or piezo-assisted injection systems. To simplify the injection procedure, we have optimized the conventional blastocyst injection method, free of laser- or piezo-assisted micromanipulation systems, to produce F0 ES cell pups. To increase the efficiency of producing mice from ES cell injection into eight-cell and blastocyst stage embryos, we have tested: 1) the effect of activating ES cell before injection, 2) the effect of in vitro culture in medium optimized for the survival of both ES cells and embryos, and 3) the effect of transferring the micromanipulated embryos into the oviduct versus into the uterus of CD1 foster mice. Two B6D2 hybrid ES cell lines were used for injection in a multifactorial analysis to evaluate the efficiency of producing live chimeric and F0 ES cell mice. Our results demonstrate that the activation of ES cells and the appropriate culture conditions are crucial parameters influencing the generation of F0 ES cell offspring. Transfer of blastocysts injected with ES cells into the oviduct of 0.5-day postcoitum pseudopregnant females increased the number of live animals with higher chimera proportion. Under these conditions, injections into eight-cell embryos produce a high number of F0 ES mice, and the conventional blastocyst injection method produces a lower number of F0 ES cell pups; however, the efficiency of production of chimeric mice with germline transmission was high. We have developed an economical and efficient technique for producing fully ES cell-derived F0 mice with full germline transmission that can be applied in many laboratories without the use of piezo or laser instruments.
Plasma 3-methylindole and Blood 3-methyleneindolenine in Feedlot Cattle (2001)

Bovine respiratory disease complex (BRD) results from an interaction of stressors, animal susceptibility and respiratory pathogens. Well known factors that increase the likelihood of BRD development include young animals, long transportation distances and dehydration. Rumen-generated toxins, such as 3-methylindole (3MI), may also be an important BRD-propagating factor.&#x0D; Animals challenged with both bovine respiratory syncytial virus (BRSV) and 3MI developed more severe respiratory disease than animals challenged with BRSV or 3MI alone.1 Further, animals with greater serum 3MI concentrations at feedlot arrival had greater odds of being treated for respiratory disease than animals with lower serum 3MI.2&#x0D; 3-methylindole must be metabolized to induce toxicity. Enzymes responsible for the bioactivation of 3MI are P450s and prostaglandin H synthetase (PHS).3,5 These enzymes are found in high concentrations in the bovine Clara cells. The putative pneumotoxic metabolite of3MI thought responsible for 3MI-induced disease is 3-methyleneindolenine (3MEIN).4 Pulmonary injury is prevented if bioactivation of 3MI is blocked.
High power, high gain optical fibre amplifier formultiwavelengthtransmission systems (1994)

A new type of optical fibre amplifier, a ‘hybrid amplifier’, especially developed for multiwavelength long distance transmission systems in the 1.55 µm window is presented. A 38 dB small signal gain, an +18 dBm saturation output power, a very flat gain spectrum and a very high signal-to-noise-ratio are obtained.
Seeing grating-textured surface begins at the border (2011)

Two experiments were conducted to reveal that the human visual system represents grating texture surface using a border-to-interior strategy. This strategy dictates that the visual system first registers the surface boundary contour and then sequentially spreads texture from the border to the interior of the image. Our experiments measured the perceived grating texture surface at various stimulus durations after the onset of a grating texture image. We found that the grating texture is initially seen near the boundary contours, with eventual spreading inward to the center of the image. To quantify the observation, the extent of the texture spreading from the boundary contour is measured as a function of the stimulus duration (30–500 ms). This allows us to analyze the texture spreading in retinal and cortical distances, based on human fMRI studies of the cortical magnification factor in cortical areas V1–V4, and to derive the spreading speed. We found that the spreading speed is constant when scaled according to the cortical distance. Similar findings are obtained no matter whether the grating texture image is presented monocularly or dichoptically, suggesting the generality of the border-to-interior strategy for representing surfaces.
On the Design of Undersampling Continuous-Time Bandpass Delta–Sigma Modulators for Gigahertz Frequency A/D Conversion (2008)

This paper describes issues and tradeoffs related to the design of undersampling delta-sigma modulators (DeltaSigmaMs) for wireless receivers. It proposes a new bandpass undersampling DeltaSigmaM architecture dedicated to multigigahertz frequencies. This paper is based on up-sampling in the feedback path to remove the analog mixer usually found in the modulator. Design equations are discussed for an optimum operating point when the input signal is at 1.8 GHz. The related design model can be applied to many communication standards. The underlying proposed architecture can receive high-frequency carriers modulated with signals of bandwidth as large as 5 MHz. In the proposed design, it converts the signal into digital data with a spurious-free dynamic range of 46 dB at a sampling frequency of 810.1 MHz. Design simulation, characterization, and implementation of the proposed modulator are done using a 0.13- mum CMOS technology.
Low dark current CMOS image sensor pixel with photodiode structure enclosed by P-well (2006)

A low dark current CMOS image sensor pixel which can be easily implemented using a standard CMOS technology without any process modification is presented. Dark current is mainly generated from the interface region between the shallow trench isolation (STI) and the active region. The proposed pixel can reduce dark current by separating the STI region from a photodiode, using a simple layout modification to enclose the photodiode junction with the P-well. A test sensor array has been fabricated using 0.18 µm standard CMOS process and its performance characterised. The dark current of the proposed pixel has been measured as 0.93fA/pixel, which is by a factor of two smaller than that of the conventional design.

A double-blind, randomized, placebo-controlled trial of eutectic lidocaine/prilocaine cream 5% (EMLA) for analgesia prior to cryotherapy of warts in children and adults. (1998)

Liquid nitrogen cryotherapy is an effective treatment modality for verrucae in children. However, sometimes the pain of the procedure is too much for the young child. In such instances the availability of an effective topical anesthetic would be of tremendous benefit. Warts are usually present on hardened skin, that is, the palms, periungual areas, and soles. In a double-blind, randomized, placebo-controlled, single-center, parallel-group trial with one visit, children (6-18 years old) and adults (>18 years old) had 2.5 g of lidocaine/prilocaine cream 5% applied under an occlusive dressing to the wart and a 1 to 2 mm area surrounding it 1 hour prior to liquid nitrogen cryotherapy. In both age groups the warts were subdivided by location-hardened skin areas versus nonhardened skin sites. The topical anesthetic was then removed and cryotherapy applied for 5 to 10 seconds. The pain of cryotherapy was assessed by the patient on a visual analogue scale (VAS) immediately after the cryotherapy and 4 and 8 hours later. There was no statistically significant difference in the pain of cryotherapy experienced following the application of active cream (n = 64) and placebo (n = 64). Exploratory subgroup analysis by wart location showed promising results for lidocaine/prilocaine cream 5% over placebo in children with warts on hardened skin sites (palms and soles). The topical anesthetic was safe and generally well-tolerated. Lidocaine/prilocaine cream 5% may provide some anesthesia in children receiving cryotherapy when the wart is on the palms or soles. Further studies are needed to better understand the site and age specificity of the anesthetic properties of lidocaine/prilocaine cream 5% when used to reduce the pain experienced during cryotherapy of warts.
An Application of QM‐QSAR to Predict and Rationalize the Refractive Index of a Wide Variety of Simple Organic/Organosilicon Molecules (2006)

Abstract The Refractive Index (RI) is a basic optical property of organic matter. In our research on dental restorative materials, RI values of monomers are important, since they affect the penetration of initiating light pulses into the forming matrix. This paper addresses the development of a general Quantum‐Mechanically based Quantitative Structure–Activity Relationship (QMQSAR) for the RI of small molecules. SAM1 is the semiempirical method used to calculate molecular properties. A training set of 75 varied molecules was used to derive the final QSAR model, which included descriptors quantifying the contributions of the relative numbers of carbon atoms and the α polarizability of the molecule. The coefficient of correlation was R 2 =0.924, and the other indicators of quality were within acceptable limits. The model demonstrated extensibility beyond the training set by predicting the refractive index of 29 molecules with an R 2 =0.913. The signed error, unsigned error and RMSE are −0.0049, 0.01412, and 0.0167 respectively. Comparison was made to existing models in the literature.
