Natural tubules Halloysite are unique and versatile material formed by surface weath- ering of aluminosilicate minerals and comprises of different proportion of aluminum, silicon, hydrogen, and oxygen. It has chemical formula of Al 4 Si 4 O 10 (OH) 8 . 4H 2 O. Nanotubular geometry of halloysites exhibit nanoscale dimensions. Basically, this tubular arrangement varies with different regions.

Use of surgery and electron beam irradiation, with or without chemotherapy, for treatment of vaccine-associated sarcomas in cats: 78 cases (1996–2000) (2001)

Results suggest that excision followed by electron beam irradiation may be beneficial for treatment of cats with vaccine-associated sarcomas. Extent of excision prior to radiotherapy did not seem to be associated with recurrence rate.
Remote Acyclic Diastereocontrol in Hydride Reductions of 1,<i>n</i>-Hydroxy Ketones (1996)

We have discovered asymmetric reductions in hydroxy ketone systems (see I) with high diastereoselectivity between remote (e.g., 1,5 and 1,6) carbon stereocenters. The favorable results are presumably achieved through the formation of bicyclic metal chelates that involve the intrachain nitrogen atom. For example, reduction of I (R = Ph, m = n = 1) with R-Alpine-Hydride or Zn(BH4)2 in CH2Cl2 gave high anti stereoselectivity (II:III = anti:syn = 10:1 or 13:1, respectively). Reduction of I (R = Ph, m = 1, n = 2) with R-Alpine-Hydride in CH2Cl2 afforded a preponderance of anti diastereomer (II:III = anti:syn = 12:1). Evidence is presented to support a chelation-controlled mechanism involving a bicyclic metal complex. Our studies with a range of substrates and reducing conditions are discussed.
High prevalence of sensitization to cat allergen among Japanese children with asthma, living without cats (1999)

Sensitization to cat allergen is common among young asthmatic patients in Japan, even among patients who do not keep cats. Use of CAP and the chimeric enzyme-linked immunosorbent assay allows accurate diagnosis of cat allergy and quantification of specific IgE antibody levels.
Adaptive Multiband Spectrum Sensing (2012)

An adaptive multiband spectrum sensing procedure is developed for fast and reliably locating multiple idle ones among a large number of channels. Through an iterative exploration process to reduce the number of candidate channels, the limited sampling budget can be focused on the more promising locations of the spectrum, resulting in significant performance improvement over the non-adaptive sensing approach. Two adaptive multi-channel sensing schemes are developed based on the energy detection and the non-parametric Komogorov-Smirnov (K-S) test, respectively. Simulation results are provided to demonstrate the effectiveness of the proposed adaptive procedure.
Influence of solvents on the formation of ultrathin uniform poly(vinyl pyrrolidone) nanofibers with electrospinning (2004)

Abstract Although there have been many reports on the preparation and applications of various polymer nanofibers with the electrospinning technique, the understanding of synthetic parameters in electrospinning remains limited. In this article, we investigate experimentally the influence of solvents on the morphology of the poly(vinyl pyrrolidone) (PVP) micro/nanofibers prepared by electrospinning PVP solution in different solvents, including ethanol, dichloromethane (MC) and N , N ‐dimethylformamide (DMF). Using 4 wt % PVP solutions, the PVP fibers prepared from MC and DMF solvents had a shape like a bead‐on‐a‐string. In contrast, smooth PVP nanofibers were obtained with ethanol as a solvent although the size distribution of the fibers was somewhat broadened. In an effort to prepare PVP nanofibers with small diameters and narrow size distributions, we developed a strategy of using mixed solvents. The experimental results showed that when the ratio of DMF to ethanol was 50:50 (w/w), regular cylindrical PVP nanofibers with a diameter of 20 nm were successfully prepared. The formation of these thinnest nanofibers could be attributed to the combined effects of ethanol and DMF solvents that optimize the solution viscosity and charge density of the polymer jet. In addition, an interesting helical‐shaped fiber was obtained from 20 wt % PVP solution in a 50:50 (w/w) mixed ethanol/DMF solvent. © 2004 Wiley Periodicals, Inc.

Enhanced Performance of Benzothieno[3,2‐<i>b</i>]thiophene (BTT)‐Based Bottom‐Contact Thin‐Film Transistors (2013)

Three new benzothieno[3,2-b]thiophene (BTT; 1) derivatives, which were end-functionalized with phenyl (BTT-P; 2), benzothiophenyl (BTT-BT; 3), and benzothieno[3,2-b]thiophenyl groups (BBTT; 4; dimer of 1), were synthesized and characterized in organic thin-film transistors (OTFTs). A new and improved synthetic method for BTTs was developed, which enabled the efficient realization of new BTT-based semiconductors. The crystal structure of BBTT was determined by single-crystal X-ray diffraction. Within this family, BBTT, which had the largest conjugation of the BTT derivatives in this study, exhibited the highest p-channel characteristic, with a carrier mobility as high as 0.22 cm(2) V(-1) s(-1) and a current on/off ratio of 1×10(7) , as well as good ambient stability for bottom-contact/bottom-gate OTFT devices. The device characteristics were correlated with the film morphologies and microstructures of the corresponding compounds.

Adjuvant Effect of Clarithromycin on Chemotherapy for Murine Lung Cancer (1999)

Clarithromycin (CAM) increased the median survival of patients with unresectable non-small-cell lung cancer who had received chemotherapy and/or radiotherapy [Chemotherapy 1997;43:288-296]. The present study was performed to ascertain whether CAM alone exhibits an antitumor effect against Lewis lung carcinoma (LLC) and to analyze the nature of its adjuvant effect on LLC-inoculated C57BL/6 mice. CAM at 10 mg/kg/day retarded the growth of subcutaneously inoculated LLC cells; consequently, the mean survival time of mice with LLC increased. This treatment was also effective in reducing the number of tumor nodules in the lung after intravenous inoculation with LLC cells. When tumor-bearing mice received an intravenous injection of vindesine sulfate (7 mg/kg) and cisplatin (6 mg/kg) 7 days after tumor inoculation, the chemotherapeutic effect was significantly enhanced by CAM treatment when it started 7 days after chemotherapy, but not when it started the day after chemotherapy. The delayed initiation of CAM treatment resulted in the enhancement of natural killer cell activity and CD8+ T cell cytotoxicity and increased the number of interferon-gamma-producing T cells and interleukin-4-producing T cells. These findings indicate that CAM can exhibit an antitumor effect by itself and also induce the well-balanced expansion of helper T cell subsets in tumor-bearing mice recovering from the immunosuppression caused by chemotherapy. CAM may therefore be a promising adjuvant drug in anticancer chemotherapy, and treatment with this macrolide should be initiated at some interval after basic cancer therapy.
The Kallikrein–Kinin System In Humans (2001)

1. Kinin peptides are implicated in many physiological and pathological processes, including the regulation of blood pressure and sodium homeostasis, inflammation and the cardioprotective effects of preconditioning. In humans, the plasma and tissue kallikrein-kinin systems (KKS) generate bradykinin and kallidin peptides, respectively. 2. We established methodology for the measurement of bradykinin and kallidin peptides and their metabolites in order to study the function of the plasma and tissue KKS in humans. 3. Bradykinin peptides were more abundant than kallidin peptides in blood and cardiac atrial tissue, whereas kallidin peptides were predominant in urine. The levels of kinin peptides in tissue were higher than in blood, confirming the primary tissue localization of the KKS. 4. Angiotensin-converting enzyme inhibition increased blood levels of bradykinin and kallidin peptides. 5. Blood levels of kallidin peptides were suppressed in patients with severe cardiac failure, indicating that the activity of the tissue KKS is suppressed in this condition. 6. Bradykinin peptide levels were increased in the urine of patients with interstitial cystitis, suggesting a role for these peptides in the pathogenesis and/or symptomatology of this condition. 7. Cardiopulmonary bypass, a model of activation of the contact system, activated both the plasma and tissue KKS. 8. Measurement of individual bradykinin and kallidin peptides and their metabolites gives important information about the operation of the plasma and tissue KKS and their role in physiology and disease states.

The subcellular localization of transglutaminase in normal liver and in glucagon-treated and partial hepatectomized rats (1983)

Rat liver was homogenized in isotonic sucrose and subjected to analytical subcellular fractionation by sucrose density-gradient centrifugation. Transglutaminase, when assayed with putrescine and dimethylcasein as substrates, showed three distinct localizations, cytosol (73%), plasma membrane (20%), and nuclei (7%). The distribution was unaffected by homogenization in the presence of potassium chloride, indicating that the particulate activity was not due to adsorbed cytosolic enzyme. The specific activity and subcellular distribution of transglutaminase in rats which had received intra-peritoneal glucagon, stimulating endocytosis, or which had been subjected to sub-total hepatectomy 2, 16, or 32 h previously, showed no significant difference from control animals.
Significant Human β-Cell Turnover Is Limited to the First Three Decades of Life as Determined by<i>in Vivo</i>Thymidine Analog Incorporation and Radiocarbon Dating (2010)

Aims: Diabetes mellitus results from an absolute or relative deficiency of insulin-producing pancreatic β-cells. The turnover rate of adult human β-cells remains unknown. We employed two techniques to examine adult human islet β-cell turnover and longevity in vivo. Methods: Subjects enrolled in National Institutes of Health clinical trials received thymidine analogs [iododeoxyuridine (IdU) or bromodeoxyuridine (BrdU)] 8 d to 4 yr prior to death. Archival autopsy samples from 10 patients (aged 17–74 yr) were employed to assess β-cell turnover by scoring nuclear analog labeling within insulin-staining cells. Human adult β-cell longevity was determined by estimating the cells’ genomic DNA integration of atmospheric (14)C. DNA was purified from pancreatic islets isolated from cadaveric donors; whole islet prep DNA was obtained from a 15-yr-old donor, and purified β-cell DNA was obtained from two donors (ages 48 and 80 yr). (14)C levels were then determined using accelerator mass spectrometry. Cellular “birth date” was determined by comparing the subject’s DNA (14)C content relative to a well-established (14)C atmospheric prevalence curve. Results: In the two subjects less than 20 yr of age, 1–2% of the β-cell nuclei costained for BrdU/IdU. No β-cell nuclei costained in the eight patients more than 30 yr old. Consistent with the BrdU/IdU turnover data, β-cell DNA (14)C content indicated that the “birth date” of cells occurred within the subject’s first 30 yr of life. Conclusions: Under typical circumstances, human β-cells and their cellular precursors are established by young adulthood.
Novel expression and transcriptional regulation of FoxJ1 during oro-facial morphogenesis (2008)

Axenfeld-Rieger syndrome (ARS) patients with PITX2 point mutations exhibit a wide range of clinical features including mild craniofacial dysmorphism and dental anomalies. Identifying new PITX2 targets and transcriptional mechanisms are important to understand the molecular basis of these anomalies. Chromatin immunoprecipitation assays demonstrate PITX2 binding to the FoxJ1 promoter and PITX2C transgenic mouse fibroblasts and PITX2-transfected cells have increased endogenous FoxJ1 expression. FoxJ1 is expressed at embryonic day 14.5 (E14.5) in early tooth germs, then down-regulated from E15.5-E17.5 and re-expressed in the inner enamel epithelium, oral epithelium, tongue epithelium, sub-mandibular salivary gland and hair follicles during E18.5 and neonate day 1. FoxJ1 and Pitx2 exhibit overlapping expression patterns in the dental and oral epithelium. PITX2 activates the FoxJ1 promoter and, Lef-1 and beta-catenin interact with PITX2 to synergistically regulate the FoxJ1 promoter. FoxJ1 physically interacts with the PITX2 homeodomain to synergistically regulate FoxJ1, providing a positive feedback mechanism for FoxJ1 expression. Furthermore, FoxJ1, PITX2, Lef-1 and beta-catenin act in concert to activate the FoxJ1 promoter. The PITX2 T68P ARS mutant protein physically interacts with FoxJ1; however, it cannot activate the FoxJ1 promoter. These data indicate a mechanism for the activity of the ARS mutant proteins in specific cell types and provides a basis for craniofacial/ tooth anomalies observed in these patients. These data reveal novel transcriptional mechanisms of FoxJ1 and demonstrate a new role of FoxJ1 in oro-facial morphogenesis.
Potential application of recycled plastic materials as a replacement for polyurethane wheels (2012)

Polyurethane (PU) has been the primary material used in skateboard wheels since the 1970s. Since then PU wheels have been used on a wide range of scooters, trolleys and other applications. Polyurethane wheels offer a smoother ride, better grip with the pavement and improved abrasion resistance compared to previous wheel materials. However, the polyurethane used for these wheels cannot be easily recycled and with the dwindling resources and ever increasing laws governing waste recycling, maintenance of resources has become increasingly important. This makes it necessary to find new uses for recycled plastics, apart from the typical low-grade uses such as packaging and road filler that result from the uncertain material properties of recycled plastics. The friction and wear of recycled plastics are often less affected by the recycling process than other material properties; consequently it is decided to study the potential application of recycled plastic materials to replace polyurethane wheels. A range of common recycled plastics are selected. These materials are then examined using a modified Plint TE57 reciprocating tribometer in sliding over an asphalt surface, using these results to analyse their friction and wear performance compared to polyurethane. A new test rig design is developed and varied contact conditions are tested. Data obtained from the tests shows that recycled polycarbonate could be a suitable replacement for polyurethane in this case with similar friction and wear results detected. Sustainability considerations regarding the use of recycled plastics are also analysed, demonstrating the advantages of the use of recycled plastics to the environment, these include reducing the CO 2 footprint by over 50%, the embedded energy consumed by 40% per wheel, and the economic material cost by 67%, among other benefits.
Raman scattering study of the high-frequency graphitic intralayer modes in Li-graphite and the stage dependence of the mode frequency in donor graphite intercalation compounds (1987)

Raman spectra of the high-frequency (\ensuremath{\sim}1600 ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}1}$) graphite interlayer modes have been studied in several Li-graphite intercalation compounds (GIC's) ${\mathrm{LiC}}_{\mathrm{p}}$=6,12,17,18. In stage-2 ${\mathrm{LiC}}_{17}$ we have also used these modes to study the T=250 K reversible structural phase transition from high-T disordered to low-T ordered Li intercalate layers and found that a Raman singlet at room temperature evolves into an unresolved Raman doublet (or triplet) below the phase transition temperature. A careful line-shape study of the low-T spectrum could not clearly distinguish between these two possibilities. A triplet is consistent, however, with previous x-ray diffraction studies of the phase transition in the bulk. Raman spectra of ${\mathrm{LiC}}_{6}$ were obtained and found to be in good agreement with previous studies. Spectra of pure stage-2 ${\mathrm{LiC}}_{12}$ were recorded for the first time. The high-frequency graphitic intralayer mode frequencies obtained in this work, together with other previously published data, indicate that a ``universal'' linear relation between mode frequency and reciprocal stage index does not exist in donor-type GIC's. That is, well outside of experimental error, the Li results show clearly that several factors (i.e., intercalate layer order, charge transfer, etc.) all make significant contributions to the small fractional change (\ensuremath{\sim}0.5%) observed in the graphitic mode frequencies. The net effect of all factors in the graphitic intralayer mode frequency is not well parametrized by the stage index alone.
Numerical Simulation of Tunnel Effect Transistors Employing Internal Field Emission of Schottky Barrier Junction (1993)

Tunnel transistors employing internal field emission of the Schottky barrier junction (SBTT) are expected to be a promising component for high-density and low-cost integrated circuits. In order to characterize the performance of SBTT, we carried out 2-D numerical simulation on four typical device structures. The output characteristics of SBTT are basically triodelike; that is, the drain current increases exponentially with increasing gate voltage, having high and nonlinear transfer performance, as elucidated by the simulation. This triodelike characteristic is observed when the channel layer is thicker than the depletion layer width formed by gate bias near the drain. In the case of a thin channel layer, a saturation feature of the drain current with increasing gate bias appears due to a pinch-off effect, which is favorable for reducing the leakage current in the off state. A prototype n-channel SBTT of crystalline silicon was fabricated and its transistor action was confirmed.

A scalable, fast, and multichannel arbitrary waveform generator (2013)

This article reports on the development of a multichannel arbitrary waveform generator that simultaneously generates arbitrary voltage waveforms on 24 independent channels with a dynamic update rate of up to 25 Msps. A real-time execution of a single waveform and/or sequence of multiple waveforms in succession, with a user programmable arbitrary sequence order is provided under the control of a stand-alone sequencer circuit implemented using a field programmable gate array. The device is operated using an internal clock and can be synced to other devices by means of transistor-transistor logic (TTL) pulses. The device can provide up to 24 independent voltages in the range of up to ± 9 V with a dynamic update-rate of up to 25 Msps and a power consumption of less than 35 W. Every channel can be programmed for 16 independent arbitrary waveforms that can be accessed during run time with a minimum switching delay of 160 ns. The device has a low-noise of 250 μV(rms) and provides a stable long-term operation with a drift rate below 10 μV/min and a maximum deviation less than ± 300 μV(pp) over a period of 2 h.
