Altered Flow–Induced Arterial Remodeling in Vimentin-Deficient Mice (2000)

The endothelial cytoskeleton plays a key role in arterial responses to acute changes in shear stress. We evaluated whether the intermediate filament protein vimentin is involved in the structural responses of arteries to chronic changes in blood flow (BF). In wild-type mice (V+/+) and in vimentin-deficient mice (V-/-), the left common carotid artery (LCA) was ligated near its bifurcation, and 4 weeks later, the structures of the occluded and of the contralateral arteries were evaluated and compared with the structures of arteries from sham-operated mice. Body weight and mean carotid artery BF did not differ between the strains, but LCA and right carotid artery (RCA) diameter (737+/-14 microm [LCA] and 723+/-14 microm [RCA] for V-/- versus 808+/-20 microm [LCA] and 796+/-20 microm [RCA] for V+/+) and medial cross-sectional area (CSAm) were significantly smaller in V-/- (21+/-1 and 22+/-2 x 10(3) microm(2) for LCA and RCA, respectively) than in V+/+ (28+/-2 and 28+/-3 x 10(3) microm(2) for LCA and RCA, respectively). In V+/+, LCA ligation eliminated BF in the occluded vessel (before ligation, 0. 35+/-0.02 mL/min) and increased BF from 0.34+/-0.02 to 0.68+/-0.04 mL/min in the RCA. In V-/-, the BF change in the occluded LCA was comparable (from 0.38+/-0.05 mL/min to zero-flow rates), but the BF increase in the RCA was less pronounced (from 0.33+/-0.02 to 0. 50+/-0.05 mL/min). In the occluded LCA of V+/+, arterial diameter was markedly reduced (-162 microm), and CSAm was significantly increased (5 x 10(3) microm(2)), whereas in the high-flow RCA of V+/+, carotid artery diameter and CSAm were not significantly modified. In the occluded LCA of V-/-, arterial diameter was reduced to a lesser extent (-77 microm) and CSAm was increased to a larger extent (10 x 10(3) microm(2)) than in V+/+. In contrast to V+/+, the high-flow RCA of V-/- displayed a significant increase in diameter (52 microm) and a significant increase in CSAm (5 x 10(3) microm(2)). These observations provide the first direct evidence for a role of the cytoskeleton in flow-induced arterial remodeling. Furthermore, they dissociate (1) between acute and chronic arterial responses to altered BF, (2) between alterations of lumen diameter and wall mass during arterial remodeling, and (3) between developmental and imposed flow-induced arterial remodeling.
Development of Laser-Produced Plasma X-Ray Source. (1998)

We developed a laboratory used laser-produced plasma X-ray source. Its characteristics concerning X-ray radiation were evaluated for Al, Ti, Fe and Nb targets in a wavelength region from 2 to 18 nm. The experimental results shows that the source has a brightness of 108∼109 photons/0.1 nm/rad2/mm2/shot at a laser intensity of 9×1012 W/cm2 and X-ray radiates with an energy conversion efficiency of about 4%. Futhermore, to demonstrate an application of the source to surface analysis, we constructed an X-ray diffractometer using the source and obtained X-ray diffraction profiles of a periodic Mo/Si multilayer structure.
Transformation and fixation of Zn in two polluted soils by changes of pH and organic ligands (2003)

Although the movement of Zn from the solid to the solution phase of soils is a significant process preceding plant uptake, the quantity of metal that can be solubilised through rhizosphere processes is also extremely important. Therefore, the consequences of plant-derived organic ligands, and changes in pH on the isotopically exchangeable quantity of Zn (E value) were examined in a polluted acid and calcareous soil. Variations in pH were facilitated through the use of dilute NaOH or HNO3 solutions. The organic ligands studied included 0.25–5 mM concentrations of sodium tartrate, the free acid and sodium salt of citrate, histidine, and deoxymugineic acid. As expected, the organic ligands and a reduction in pH increased the solution concentration of Zn in these soils. Furthermore, through the application of isotopic dilution techniques, it was determined that some of these organic ligands could significantly increase the quantity of isotopically exchangeable Zn. However, with the exception of the 5 mM sodium citrate treatment in the calcareous soil, pH was the overriding parameter that effected changes in the E value. Reducing the pH by approximately 2 units increased the E value by 39 and 80%, respectively, in the acid and calcareous soil. Conversely, evidence for Zn fixation (a decrease of the E value) was observed in the acid soil when pH was increased. The exudation of organic ligands and variations of pH induced by plants have the potential to significantly vary the quantity of phytoavailable Zn in these 2 polluted soils.

Sixteen percent of patients with established MS were subsequently found to have been misdiagnosed. Women were at higher risk for misdiagnosis. Expert application of the McDonald criteria may prevent misdiagnosis and its associated morbidity and healthcare system cost.
Purification and properties of closterovirus‐like particles associated with a whitefly‐transmitted disease of sweet potato (1992)

Summary A virus causing sunken veins on ‘Georgia Jet’ sweet potato, and yellow brittle leaves and stunting on Ipomoea setosa , was purified and a specific antiserum was prepared. Flexuous particles with a normal length of 850 nm and a diameter of 12 nm with an open helical structure typical of closteroviruses were observed. The virus particle protein has an apparent mol. wt of c. 34 kD. Double‐stranded RNA isolated from SPSVV‐infected I. setosa and subjected to electrophoresis in agarose consisted of one major band with an estimated M r of 10.5 kbp and two minor bands with M r of 9.0 and 5.0 kbp. Fibril‐containing vesicles in phloem cells were observed in ultrathin sections of infected leaf tissues. The virus was transmitted by the whitefly Bemisia tabaci in a semi‐persistent manner and by grafting, but not mechanically. The virus could be transmitted to various Ipomoea species, to Nicotiana clevelandii, N. benthamiana and Amaranthus palmeri. The virus did not react with an antiserum to lettuce infectious yellows virus. Based on particle morphology, serology and symptom expression, the virus appears unique and different from all other reported whitefly‐transmitted closteroviruses. We propose it be named “sweet potato sunken vein virus” (SPSVV).
Synthese von Pyrazolo[3,4‐b]chinolinen aus 4‐Aroyl‐5‐chlor‐pyrazolen (1990)

Synthesis of Pyrazolo[3,4‐b]quinolines from 4‐Aroyl‐5‐chloropyrazoles The reaction of 4‐aroyl‐5‐chloro‐3‐methyl‐1‐phenyl‐pyrazoles 1 with an excess of 3‐ or 4‐substituted and 3,4‐disubstituted anilines 2 gives pyrazolo [3,4‐b]quinolines 4a‐k . Information about the reaction mechanism was obtained by the isolation of the intermediate product 3e . In some cases it was possible to isolate subsequent products 41‐p . The reaction of 1a with 5‐amino‐3‐methyl‐1‐phenyl‐pyrazole ( 5 ) gives a bispyrazolopyridine derivative 6 .
Theoretical aspects of one-point calibration: causes and effects of some potential errors, and their dependence on concentration. (1984)

The potential errors of the one-point calibration technique are described mathematically. I examine the theoretical causes and effects of analytical errors in absorbance and of errors in determining calibration concentration, and discuss techniques for minimizing their impact. The dependence of these errors on the calibration concentration and on the size of the result is considered, and some conclusions are drawn about the choice of calibration concentration.
Effect of Grain Boundaries on Charge Transport in Methylammonium Lead Iodide Perovskite Thin Films (2019)

Methylammonium lead iodide (MAPbI₃) has attracted great interest as an organic–inorganic hybrid perovskite for photovoltaic applications. Vacancy-mediated ion migration is one of the dominant carrier transport mechanisms in MAPbI₃. Our previous work clarified the nature of migrating species and their moderating effect on electronic transport. However, to develop strategies to mitigate ion migration and its impact thereof, it is important to know whether the migration is homogeneous or controlled by microstructural features, such as grain boundaries. In this work, we implement temperature-dependent pulsed voltage–current measurements of MAPbI₃ thin films with different grain sizes under dark conditions and distinguish the electromigration of iodine vacancies and methylammonium vacancies. Upon increasing the grain size, the total accumulated charge decreases, whereas the activation energies increase. This is consistent with the high grain boundary density in small-grained films responsible for facilitating charge transport. These results suggest that one viable strategy to decrease ion migration would be to engineer the grain boundaries of MAPbI₃.
Molecular film growth monitoring via reflection microscopy on periodically patterned substrates (2013)

An optical method is presented for in the situ monitoring of biomolecular films via reflection microscopy on patterned substrates. The method is based on measuring the reflection coefficient of a composite consisting of a substrate, a patterned optical layer, the thin film to be monitored and the cover medium. The optical layer is patterned so that an array of squares is surrounded by the bare substrate. The reflectance difference between the optical layer squares and the bare substrate is the observable, whose fractional changes reveal the thickness of the film through a simple analytical expression. The periodic image is recorded by a digital microscope, and through Fourier transform techniques, the normalized differential reflectance of the patterned optical composite is calculated as the contrast factor of two dimensional bit map. The method is demonstrated by measuring a protein binding assay inside a microfluidic module placed under a microscope.
Increased resistance to antifungal antibiotics ofCandida spp. adhered to silicone (1995)

The minimal inhibitory concentrations (MICs) and minimal fungicidal concentrations (MFCs) of amphotericin B, miconazole, ketoconazole, fluconazole, and itraconazole were determined for non-adhered cells and cells adhered to sections of a silicone urinary catheter. The densities of adhered cells were established with cells radiolabeled with tritiated leucine. Well defined MICs and MFCs were established for amphotericin B for representative adhered strains. In contrast, the azoles, especially fluconazole, did not give clear end points and the MICs and MFCs were arbitrarily determined. MFCs for the adhered cells generally were 2- to 5-fold higher than those of non-adhered cells. Techniques that include adhered-cell susceptibilities may be necessary before antifungal regimens for prosthetic device-associated yeast infections are appropriately defined.
Process latitude and CD bias evaluation of attenuated PSM (1997)

The application of an attenuated PSM for printing contact hole layers is one way to extend the useful lifetimes of an I-line stepper. The development of such a process needs to consider more than just the traditional parameters. Selecting the optimum mask CD bias, stepper NA, sigma, exposure, and focus, is even more critical than for the process using conventional binary masks due to sidelobe printing with attenuated PSM. Using an electrical CD measurement technique, this study was able to evaluated process latitude at various stepper and mask bias settings, at one point and at sixteen points per field. One of the resists tested showed 0.85 micrometers depth of focus and &gt; 20% exposure latitude for 0.30 micrometers contacts on 0.75 micrometers pitch. The overlapping process window at sixteen points per field is much smaller than that at only one point per field, justifying the need for such an evaluation. Full wafer CD mapping allowed us to quantify across wafer and across field CD variation. Though the electrical measurements exhibited excellent correlation with SEM measurements (R<SUP>2</SUP> equals 0.994), it is still necessary to verify a chosen process under SEM inspection to evaluate the resist profile for any artifacts such as sidelobe printing.
Quasi-monochromatic parallel radiography achieved with a plane-focus x-ray tube (2002)

Fundamental study on quasi-monochromatic parallel radiography using a polycapillary plate and a plane-focus x-ray tube is described. The x-ray generator consists of a negative high-voltage power supply, a filament (hot cathode) power supply, and an x-ray tube. The negative high-voltage is applied to the cathode electrode, and the transmission type target (anode) is connected to the ground potential. The maximum voltage and current of the power supply were -100 kV (peak value) and 3.0 mA, respectively. In this experiment, the tube voltage was regulated from 20 to 25 kV, and the tube current was regulated by the filament temperature and ranged from 1.0 to 3.0 mA. The exposure time is controlled in order to obtain optimum film density, and the focal spot diameter was about 10 mm. The polycapillary plate is J5022-21 made by Hamamatsu Photonics Inc., and the outside and effective diameters are 87 and 77 mm, respectively. The thickness and the hole diameter of the polycapillary are 1.0 m and 25 &mu;m, respectively. The x-rays from the t ube are formed into parallel beam by the polycapillary, and the radiogram is taken using an industrial x-ray film of Fuji IX 100 without using a screen. In the measurement of image resolution, we employed three brass spacers of 2, 30, and 60 mm in height. By the test chart, the resolution fell according to increases in the spacer height without using a polycapillary. In contrast, the resolution slightly fell with corresponding increases in the height by the polycapillary. In angiography, fine blood vessels of about 100 &mu;m are clearly visible.
Pleckstrin homology-like domain family A, member 3 (PHLDA3) deficiency improves islets engraftment through the suppression of hypoxic damage (2017)

Islet transplantation is a useful cell replacement therapy that can restore the glycometabolic function of severe diabetic patients. It is known that many transplanted islets failed to engraft, and thus, new approaches for overcoming graft loss that may improve the outcome of future clinical islet transplantations are necessary. Pleckstrin homology-like domain family A, member 3 (PHLDA3) is a known suppressor of neuroendocrine tumorigenicity, yet deficiency of this gene increases islet proliferation, prevents islet apoptosis, and improves their insulin-releasing function without causing tumors. In this study, we examined the potential use of PHLDA3-deficient islets in transplantation. We observed that: 1) transplanting PHLDA3-deficient islets into diabetic mice significantly improved their glycometabolic condition, 2) the improved engraftment of PHLDA3-deficient islets resulted from increased cell survival during early transplantation, and 3) Akt activity was elevated in PHLDA3-deficient islets, especially under hypoxic conditions. Thus, we determined that PHLDA3-deficient islets are more resistant against stresses induced by islet isolation and transplantation. We conclude that use of islets with suppressed PHLDA3 expression could be a novel and promising treatment for improving engraftment and consequent glycemic control in islet transplantation.
Fabrication of photonic band gap materials using microtransfer molded templates (2003)

A method of manufacturing photonic band gap structures operable in the optical spectrum has been presented. The method comprises the steps of creating a patterned template for an elastomeric mold, fabricating an elastomeric mold from poly-dimethylsiloxane (PDMS) or other suitable polymer, filling the elastomeric mold with a second polymer such as epoxy or other suitable polymer, stamping the second polymer by making contact with a substrate or multilayer structure, removing the elastomeric mold, infiltrating the multilayer structure with ceramic or metal, and heating the multilayer structure to remove the second polymer to form a photonic band gap structure.
Micromachining optical waveguides in bulk glass using a femtosecond laser oscillator (2000)

Summary form only given.We show that by focusing a femtosecond laser pulse very tightly, one can micromachine a transparent material using an unamplified laser. A 1.4 numerical aperture (NA) microscope objective is used to focus a 5 nJ, sub-100-fs pulse into a 0.5-/spl mu/m diameter spot inside a piece of Corning 0211 glass.
Efficient view-dependent LOD control for large 3D unclosed mesh models of environments (2004)

The rapid progress of 3D modeling techniques have brought more and more applications of 3D range data in robotics. However, the 3D data we acquire with range finders mounted on mobile robots are usually too large to process in real-time, and holes and boundaries are unavoidable on the surface it represents. One method to resolve this problem is to perform mesh simplification and level of detail (LOD) control on these models. A new method based on progressive meshes (PMs) is proposed in this paper, which adopts different simplification and remeshing strategies on different boundary conditions, and therefore well preserves geometrical features on the boundaries through the simplification. The detail records are organized in a forest-shaped data structure at the same time. Hence, when a scene is reconstructed using the multiresolution models, the local details can be rapidly added by selective refinement. Furthermore, continuous view-dependent distributions of LOD are also supported to provide efficient scene representation and rendering.
Siglec-F–expressing neutrophils are essential for creating a profibrotic microenvironment in renal fibrosis (2022)

The roles of neutrophils in renal inflammation are currently unclear. On examining these cells in the unilateral ureteral obstruction murine model of chronic kidney disease, we found that the injured kidney bore a large and rapidly expanding population of neutrophils that expressed the eosinophil marker Siglec-F. We first verified that these cells were neutrophils. Siglec-F+ neutrophils were recently detected in several studies in other disease contexts. We then showed that a) these cells were derived from conventional neutrophils in the renal vasculature by TGF-β1 and GM-CSF; b) they differed from their parent cells by more frequent hypersegmentation, higher expression of profibrotic inflammatory cytokines, and notably, expression of collagen 1; and c) their depletion reduced collagen deposition and disease progression, but adoptive transfer increased renal fibrosis. These findings have thus unveiled a subtype of neutrophils that participate in renal fibrosis and a potentially new therapeutic target in chronic kidney disease.
Tracking the Fate of Microbially Sequestered Carbon Dioxide in Soil Organic Matter (2013)

The microbial contribution to soil organic matter (SOM) has recently been shown to be much larger than previously thought and thus its role in carbon sequestration may also be underestimated. In this study we employ (13)C ((13)CO₂) to assess the potential CO₂ sequestration capacity of soil chemoautotrophic bacteria and combine nuclear magnetic resonance (NMR) with stable isotope probing (SIP), techniques that independently make use of the isotopic enrichment of soil microbial biomass. In this way molecular information generated from NMR is linked with identification of microbes responsible for carbon capture. A mathematical model is developed to determine real-time CO₂ flux so that net sequestration can be calculated. Twenty-eight groups of bacteria showing close homologies with existing species were identified. Surprisingly, Ralstonia eutropha was the dominant group. Through NMR we observed the formation of lipids, carbohydrates, and proteins produced directly from CO₂ utilized by microbial biomass. The component of SOM directly associated with CO₂ capture was calculated at 2.86 mg C (89.21 mg kg(-1)) after 48 h. This approach can differentiate between SOM derived through microbial uptake of CO₂ and other SOM constituents and represents a first step in tracking the fate and dynamics of microbial biomass in soil.
Hybrid WDM/TDM passive optical network with dynamic virtual PON (VPON) capability (2010)

We propose a novel hybrid WDM/TDM-PON with dynamic Virtual PON (VPON) capability. ONUs in the network can dynamically form a virtual TDM-PON to increase bandwidth and optimize network resource. The VPON is achieved without using additional lasers and tunable lasers. Experiment of 10-Gb/s downstream and 1.25-Gb/s upstream transmissions verifies the proposed scheme.
A PSK Modulation Scheme for Sensor Integrated RFIDs (2019)

In this paper, a PSK based modulation scheme is proposed in the RFID framework for transmitting at high bit rates from the tag. The PSK modulation circuit is compatible with the existing passive RFID tag RF front end circuit. The modulation scheme is useful for high speed sensor integrated with RFID applications. The PSK modulation and demodulation circuits are fabricated on PCB and the measurement results are reported.
