Intravenous 3‐Methoxy‐O‐Desmethyl‐Encainide in Reentrant Supraventricular Tachycardia: A Randomized Double‐Blind Placebo‐Controlled Trial in Patients Undergoing EP Study (1991)

Encainide is an agent effective in atrioventricular and atrioventricular nodal reentrant tachycardia. The metabolites O-desmethyl encainide and 3-methoxy-O-desmethyl encainide (MODE) are responsible for the clinical effects of encainide in most patients. In this study, intravenous MODE was evaluated in eight patients with reentrant supraventricular tachycardia undergoing electrophysiological testing. After tachycardia was induced at least twice to ensure reproducibility, MODE (30 micrograms/kg/min x 15 min, then 7.5 micrograms/kg/min) or placebo was administered in a double-blind fashion. If tachycardia remained inducible, the infusion was unblinded; in nonresponding subjects who received placebo, MODE was then administered. Placebo was ineffective in 3/3 patients. MODE prevented tachycardia induction in 5/8 patients and increased the tachycardia cycle length from 302 +/- 38 to 413 +/- 67 msec in the other three. At a mean concentration of 774 +/- 229 ng/ml, MODE prolonged PR, AH, HV, QRS, and QT intervals, right ventricular and accessory pathway effective refractory periods, and slowed or blocked antegrade accessory pathway conduction. Changes in intracardiac conduction were rate independent between cycle lengths 400 to 600 msec, while changes in ventricular effective refractory periods were most pronounced at rapid pacing rates. No adverse effects, hemodynamic changes, or conduction disturbances occurred. Thus, MODE can modify or suppress induction of reentrant atrioventricular or atrioventricular nodal tachycardia. The study design used here is well suited for the evaluation of newer antiarrhythmic agents by electrophysiological testing.
Reduced Sample Number for Calculation of Insulin Sensitivity and Glucose Effectiveness From the Minimal Model: Suitability for Use in Population Studies (1993)

The FSIGT has been extensively applied to the minimal model of glucose kinetics to obtain noninvasive measures of Sl. The protocol has been modified by the addition of a bolus tolbutamide or insulin injection 20 min after glucose. Although the modified protocol has improved the Sl estimate, the method still requires a relatively large number of samples (n = 30). To reduce the total number of samples, we choose a sample schedule that minimizes the variance of the parameter estimates and the error in reconstructing the plasma insulin profile. With data from 10 subjects (BMI 30 +/- 7 kg/m2; Sl 0.9-10.2 x 10(-4) min-1.microU-1 x ml-1), a schedule consisting of 12 samples (0, 2, 4, 8, 19, 22, 30, 40, 50, 70, 90, and 180 min) was obtained. Estimates of Sl obtained from the reduced sampling schedule were then compared with those obtained with the full sampling schedule. In all 10 individuals, the Sl estimates were almost identical. A second, much larger data base consisting of 118 modified FSIGTs performed in 87 subjects (67 men, 20 women; BMI from 19.6 to 40 kg/m2 for men and 26.7 to 52.5 for women; Sl from 0.35 to 14.1 x 10(-4) min-1 x microU-1 x ml-1) was then used to independently assess the efficacy of the reduced sampling protocol. For this data base, the correlation between Sl, which was calculated from the full versus the reduced sampling schedule, was 0.95. The mean relative deviation was -1.5% (not significantly different from zero), and the SD of the relative deviation was 20.2%.(ABSTRACT TRUNCATED AT 250 WORDS)
Activation of antigen-presenting cells by microbial products breaks self tolerance and induces autoimmune disease (2004)

We describe the generation of mice that express a transgenic T cell receptor (TCR) (5B6) specific for the encephalitogenic myelin proteolipid protein (PLP) peptide 139–151, on the experimental autoimmune encephalomyelitis–resistant (EAE-resistant) B10.S background. Despite harboring a high frequency of self-reactive T cells, 5B6 transgenic mice on the B10.S background rarely develop spontaneous EAE, which is in striking contrast to 5B6 transgenic mice on the EAE-susceptible SJL background. The relative resistance to spontaneous EAE in transgenic B10.S mice is not due to deletion or anergy of T cells, but appears to be controlled by APCs. Analysis of APCs revealed a lower activation state and a lower T cell–activating capacity for APCs from B10.S mice than for those from EAE-susceptible SJL mice. When APCs in 5B6 transgenic B10.S mice were activated, for example, via TLR9 or TLR4, T cell tolerance was broken, resulting in EAE. Our findings demonstrate that activation of APCs via innate immune receptors can break self tolerance and trigger the development of autoimmunity even in a genetically resistant strain. These findings suggest that the development of autoimmune diseases such as multiple sclerosis is determined at least partly by the endogenous activation state of APCs.
B Cell Hybridoma Presents Both B-Cell and T-Cell Epitopes for Stimulating Antibody Production Via CD23 Pathway (1996)

CD23+ B cell hybridoma 17A11, pulsed with IgE:TNP-KLH triggered IgA, IgG, and IgE antibody production via CD23-mediated presentation. Prior anti-CD23 treatment abrogated 95% of the humoral antibody responses. Both B and T cell epitopes were presented by 17A11 B cell epitopes as recognized by IgG but not T cell epitopes were sensitive to treatment with 0.2 M acetic acid. Efficacy of antigen presentation via CD23 on 17A11 was comparable to that mediated via surface immunoglobulins (sIg) on a CD23 negative 4.5 parental fusion partner B cell line. This is the first demonstration that IgE:TNP-KLH pulsed B cell hybridomas present both B- and T-cell epitopes in stimulating IgA, IgG, and IgE antibody production, and raise a pertinent issue whether IgE antibodies produced under pathophysiological conditions may serve as positive feedback signal for sustaining production of different classes of antibodies.

Human Monocytic Cell Lines Transformed In Vitro by Epstein-Barr Virus Display a Type II Latency and LMP-1-Dependent Proliferation (2002)

Epstein-Barr virus (EBV) classically infects and transforms B lymphocytes in vitro, yielding lymphoblastoid cell lines (LCLs). In contrast to other herpesviruses, EBV is not described as an infectious agent for monocytes. However, recent papers described in vitro infection of monocytes leading to abortive or transient viral expression. In the present study, we report the characterization of E1, a monocytic cell line infected and transformed by EBV. This cell line was derived from an LCL by a drastic electroporation and selection of neomycin-resistant cells, unfavorable to B-cell outgrowth. E1 expressed surface molecules of monocytic lineage (CD14, major histocompatibility complex class II, and CD80) and the c-fms gene, a highly specific marker for the monocytic lineage. This cell line is able to phagocytose and secrete proinflammatory monokines tumor necrosis factor alpha, interleukin-6 (IL-6), and IL-8. E1 cells are tumorigenic after injection in nude mice, and a monocytic cell line obtained from one of these tumors (TE1) displayed immunophenotype and functional properties similar to those of E1. We detected the presence of the EBV genome in both cell lines, as well as expression of the EBNA-1 and LMP-1, but not EBNA-2, viral genes, characteristic of a type II latency. LMP-1 influences the phenotype of these monocytic cell lines, as demonstrated by down-regulation of cell proliferation and membrane intercellular adhesion molecule 1 expression due to an LMP-1 antisense strategy. This is the first description of a latently infected human monocytic cell line and the first direct demonstration of an instrumental role for LMP-1 in the proliferation of EBV-transformed cell lines expressing a type II latency.

Controlled-release of Chlorine Dioxide in a Perforated Packaging System to Extend the Storage Life and Improve the Safety of Grape Tomatoes (2017)

A controlled-release chlorine dioxide (ClO2) pouch was developed by sealing a slurry form of ClO2 into semipermeable polymer film; the release properties of the pouch were monitored in containers with or without fruit. The pouch was affixed to the inside of a perforated clamshell containing grape tomatoes, and the effect on microbial population, firmness, and weight loss was evaluated during a 14 day storage period at 20 °C. Within 3 days, the ClO2 concentration in the clamshells reached 3.5 ppm and remained constant until day 10. Thereafter, it decreased to 2 ppm by day 14. The ClO2 pouch exhibited strong antimicrobial activity, reducing Escherichia coli populations by 3.08 log CFU/g and Alternaria alternata populations by 2.85 log CFU/g after 14 days of storage. The ClO2 treatment also reduced softening and weight loss and extended the overall shelf life of the tomatoes. Our results suggest that ClO2 treatment is useful for extending the shelf life and improving the microbial safety of tomatoes during storage without impairing their quality.

A Facile One-Pot Synthesis of 7-Triethylsilylbaccatin III (2005)

Correlation Between Aortic Motion and Vessel Bulging in a Murine Aneurysm Model Using Small Animal Magnetic Resonance Imaging (2009)

Abdominal aortic aneurysm (AAA), defined as a 1.5-fold or greater increase in vessel diameter, leads to approximately 15,000 deaths per year in the United States. While the clinical morbidities are well-known, a detailed understanding of the underlying mechanisms that lead to initiation of the disease and progressive expansion of the vessel remain elusive. Murine AAA models have been developed to aid in better understanding the condition in humans. However, aneurysm research in mice to date has been limited to assessment of vessel growth by invasive or 2D ultrasound methods and has not considered wall dynamics. Thus, the purpose of this study was to characterize wall motion and aortic displacement in mouse aortas by developing high spatial and temporal resolution MR imaging and vessel quantification methods, with the goal of comparing the motion of healthy vasculature to the direction of AAA bulging.
Sn-Ag-Cu Soldering Reliability Influenced by Process Atmosphere (2007)

To develop an optimal soldering process of Sn-Ag-Cu soldered joints, the influences of atmosphere and cooling speed during reflow treatment on soldering reliability have been examined through the use of Sn plated chip components and of Pd plated small outline packages (SOPs) on a printed circuit board (PCB) soldered with Sn-3wt.%Ag-0.5wt.%Cu, Sn-3.8wt.%Ag-0.75wt.%Cu and Sn-4wt.%Ag-0.9wt.%Cu solder pastes under air or N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> atmospheres. In the case of chip component joints, the solder compositions, cooling speed and atmospheres during reflow treatment slightly affect the dendritic microstructure. Those parameters rarely affect the wetting behavior and mechanical properties. In the case of SOP joints, however, the atmospheres during reflow treatment and fluxes strongly affect the appearances of fillet surfaces structure. Despite the types of solder fluxes, N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> process atmosphere obviously improved wettability of solder on lead-frame of the SOP.
Human metapneumovirus infection in Korean children (2006)

Purpose:Human metapneumovirus(hMPV) is a respiratory viral pathogen that causes a wide spectrum of illnesses, ranging from asymptomatic infection to severe bronchiolitis. The virus has been identified world widely, but so far it has not been published in Korea. Methods:We obtained clinical samples by nasopharyngeal aspiration from 218 children hospitalized due to acute lower respiratory tract infections at Soonchunhyang University Hospital in Cheonan from October, 2004 to April, 2005. We designed specific primers from conserved region of fusion glycoprotein of hMPV. Total RNA was extracted and RT-PCR was performed, and single specific 423 bp product was obtained. The PCR product was confirmed to be fusion glycoprotein RNA by sequencing. Results:We detected hMPV in 15(6.9 percent) of the 218 hospitalized children. The infected children comprised nine boys and six girls; their mean age was 2.8 years(5 mo-12 yrs) and they were diagnosed with pneumonia(60 percent), bronchiolitis(33.3 percent), croup(6.6 percent). The number of cases of detected hMPV in Korea increased dramatically during the period from March to May 2005. Conclusion:hMPV is circulating in Korean children and is associated with respiratory tract infection. Additional studies are required to define the epidemiology and the extent of diseases in the general population caused by hMPV.
The heating rate dependence of polymer melting points (1979)

Abstract The melting points ( T m ) of small quantities (ca. 0.1 mg) of polyethylene (PE) single crystals in the dried state and in suspension were determined as a function of heating rate. Melting points were also obtained for large amounts (ca. 3 mg) of dried‐down crystals. It has been reported previously that PE crystals of high molecular weight possess a single melting point and this T m decreases with increasing heating rate. However, all samples in our study show multiple melting behavior. Moreover, suspension samples show little or no variation in the various peak temperatures with heating rate. There is some dependence of T m on heating rate for small dry samples but the change in T m is not nearly as great as previously reported. These small changes can be the result of the relatively poor resolution of small dry samples compared to suspension. Differences between the behavior reported here and those of other authors can be explained on the basis of the relative contributions to the various melting endotherms.
Colonic antibody responses in pigs with swine dysentery (2009)

Swine dysentery (SD) is a mucohaemorrhagic colitis of pigs resulting from infection of the large intestine with the anaerobic intestinal spirochaete Brachyspira hyodysenteriae. The infection has been reported to result in the development of specific IgG, IgA and IgM antibodies in serum and the production of secretory IgA in the gut mucosa (Rees et al., 1989). The hypothesis tested in this experiment was that colonic antibody levels can be used as a diagnostic tool to assist the diagnosis of SD. The experimental design involved testing samples from non-infected pigs to define appropriate cut-off values for the assays, and then using these in assays of serum and colonic samples from pigs that had been experimentally exposed to B. hyodysenteriae.
Spectral Bias in Adaptive Beamforming With (2009)

It is shown that adaptive canceling arrays which track interference by regular updates of the beamformer weights can introduce a null at the excised interference frequency. This PSD estimation bias effect we call spectral is most prominent for narrowband interference (i.e., occupying only a few bins at the desired PSD estimation resolution). Scooping is problematic in radio astronomy where bias in either the weak signal or noise floor spectra can corrupt the observation. The mathematical basis for scooping is derived, and an algorithm to eliminate it is proposed. Both simulated and real data experiments demonstrate the effectiveness of the proposed algorithm. Index Terms—Adaptive arrays, interference suppression, radio astronomy, analysis.
Isolation and Characterization of a Novel Thermophilic Methanosaeta Strain (1991)

A novel thermophilic acetotrophic Methanosaeta strain was isolated from a thermophilic anaerobic digest or by using acetate enrichment and serial dilution in the presence of vancomycin and neomycin. This isolate, designated Methanosaeta sp. strain PT, resembled Methanosaeta sp. strain CALS-1 morphologically; however, it occasionally formed filaments longer than 100 μm and exhibited autofluorescence. The content of coenzyme F420 was much higher than that of Methanosaeta reference strains, and coenzyme F420 with four glutamyl residues on the side chain was the predominant component. Furthermore, a comparative analysis of the antigenic fingerprint of strain PT with the fingerprints of reference organisms showed that this isolate was not related antigenically to the reference methanogens, including Methanosaeta sp. (“Methanothrix” sp.) strain CALS-1 and Methanosaeta concilii (“Methanothrix soehngenii”) Opfikon. Strain PT formed visible colonies in a deep agar medium when high cell concentrations were present. However, transfer of a colony into liquid medium resulted in no growth. Strain PT could utilize only acetate as a sole carbon and energy source. The optimum temperature and optimum pH for methanogenesis were near 55°C and 6.7, respectively. The specific methane formation rate μCH 4 under optimum conditions was 0.47 day−1, and the doubling time was 1.49 days. The DNA base composition was 52.7 mol% guanine plus cytosine.
Impact of atomic layer deposition temperature on HfO2/InGaAs metal-oxide-semiconductor interface properties (2012)

We have studied the impact of atomic-layer-deposition (ALD) temperature on the HfO2/InGaAs metal-oxide-semiconductor (MOS) interface with a comparison to the Al2O3/InGaAs interface. It is found that the interface properties such as the C-V characteristics and the interface trap density (Dit) and the interface structure of HfO2/InGaAs have strong dependence on the ALD temperature, while the Al2O3/InGaAs interfaces hardly depend on it. As a result, we have achieved the HfO2/InGaAs interfaces with low Dit comparable to that in the Al2O3/InGaAs interface by lowering the ALD temperature down to 200 °C or less. Also, we have found that As2O3 and Ga2O3 formed at the interface during ALD increase with a decrease in the ALD temperature. Combined with the ALD temperature dependence of the electrical characteristics, the better C-V characteristics and the lower Dit obtained at the lower ALD temperature can be explained by the As2O3 and Ga2O3 passivation of the HfO2/InGaAs interfaces, which is consistent with a reported theoretical result on the effective passivation of III-V MOS interfaces by trivalent oxides.
Synthesis of New 3′-Deoxyribonucleosides Employing the Acid-Catalyzed Fusion Method (1998)

Coupling of 4,6-dichloro-1H-imidazo[4,5-c]pyridine (2,6-dichloro-3-deaza-9H-purine) (1) with 1,2-O-di-acetyl-5-O-benzoyl-3-deoxy-β-D-ribofuranose (2), employing the acid-catalyzed fusion method, is reported (Scheme 1). The condensation reaction was regioselective and gave the three N1-glycosylation products 3 – 5, whereas no N3-nucleosides were detected. Treatment of 3 – 5 with methanolic ammonia afforded the corresponding deprotected nucleosides 6 – 8. Compounds 6 and 7 were assigned the structure of the β-D- and α-D-anomeric N1-(3′-deoxyribo)nucleosides, respectively. The third derivative 8 proved to be the α-D-anomer of a 3′-deoxyarabinonucleoside deriving from epimerization at C(2) of the sugar. The 2-chloro- and N6-substituted derivatives 9, 11, and 13 of 3′-deoxy-3-deazaadenosine (10) and of its α-D-anomer 12 can be obtained from these versatile synthons (Schemes 2 and 3).
