Generation of atomic nitrogen flux monitoring by an atomic absorption detection system at 120 nm (1999)

We have demonstrated a lamp-based atomic absorption detection system at 120 nm for monitoring atomic nitrogen generation in microwave discharge. Atomic nitrogen flux and dissociation ratio were evaluated by the atomic absorption. Delivery of atomic nitrogen with a quartz tube was investigated. By suppressing the recombination of the atomic nitrogen with the Teflon insert, the delivered atomic nitrogen flux was enhanced by a factor of 3–10. At a microwave power of 300 W, an atomic flux of 5×1016 cm−2 s−1, sufficient for growth of nitride thin films, was achieved. A model of recombination was used for explaining the experimental results, a maximum dissociation ratio of ∼2% at the plasma region was estimated based on the measured atomic nitrogen densities.
Electron-beam processing of destructurized allylurea-starch blends: Immobilization of plasticizer by grafting (1999)

Allylurea (AU) was used as a reactive additive with poor aptitude to homopolymerization for obtaining grafted plasticized starch films with stabilized physical properties. Potato starch was mixed with AU (30–50 parts per hundred/pph) in a mixer operating at 125°C. Upon storage in well-defined hygrothermal conditions, the resulting thermoplastic material shows strong plasticizer migration revealed by AU crystals blooming at the samples surface and exhibits strong opacity assigned to phase separation of the organic additive inside the material. Freshly prepared thermoplastic films of appropriate thickness were exposed to a 175-kV electron beam (EB) radiation for inducing covalent grafting of AU by a free radical process. FTIR monitoring of the resulting chemical changes in thin films of AU–starch blends indicates unambiguously the transformation of AU allylic bond. High irradiation doses are required for achieving complete conversion of AU in the blend. However, no detectable AU migration was observed for intermediate AU conversion, probably as a consequence of higher plasticizer solubility in the grafted polysaccharide. Examination of the viscoelastic properties by dynamic mechanical thermal analysis shows that artificial aging by placing the films alternatively in high and low relative humidity (RH) atmosphere does not significantly alter the thermomechanical spectrum of the material reconditioned in a cell at 58% RH. © 1999 John Wiley & Sons, Inc.

Analysis of ephrin‐A2 in the chick retinotectal projection using a function‐blocking monoclonal antibody (2001)

Eph receptor tyrosine kinases and their ligands have been shown to be involved in processes of cell migration and axon guidance during embryonic development. Here we describe the development of a function-blocking monoclonal antibody against chick ephrin-A2, and its effect on retinal ganglion cell axons studied both in vitro and in vivo. In the stripe assay, the blocking antibody completely abolished the repulsive effect of posterior tectal membranes. In vivo, in a loss-of-function approach, hybridoma cells secreting the antiephrin-A2 antibody were applied to chick embryos from embryonic day 3 (E3) on, and the retinotectal projection was subsequently analyzed at E16. DiI tracing analyses showed that although the projection of both temporal and nasal retinal ganglion axons in the tectum was, overall, normal, occasionally diffuse and extra termination zones were observed, in addition to axons over-shooting their termination zones. These data support the idea that ephrin-A2 contributes to the establishment of the chick retinotectal projection.
Fiber-chip edge coupler with large mode size for silicon photonic wire waveguides (2015)

Fiber-chip edge couplers are extensively used in integrated optics as one of the key structures for coupling of light between planar waveguide circuits and optical fibers. In this work, a new fiber-chip edge coupler concept with large mode size for coupling to submicrometer silicon photonic wire waveguides is presented. The coupler allows direct coupling to conventional SMF-28 optical fiber and circumvents the need for lensed fibers. We demonstrate by simulations a 95% mode overlap between the mode at the chip facet and a high numerical aperture single mode optical fiber with 6 μm mode field diameter (MFD). We also demonstrate a modified design with 89% overlap between the mode at the chip facet and a standard SMF-28 fiber with 10.4 μm MFD. The coupler is designed for 220 nm silicon-oninsulator (SOI) platform. An important advantage of our coupler is that large mode size is obtained without the need to increase buried oxide (BOX) thickness, which in our design is set to 3 μm. This remarkable feature is achieved by implementing in the SiO<sub>2</sub> upper cladding two thin high-index Si<sub>3</sub>N<sub>4</sub> layers. The high-index layers increase the effective refractive index of the upper cladding layer near the facet and are gradually tapered out along the coupler to provide adiabatic mode transformation to the silicon wire waveguide. Simultaneously, the Si-wire waveguide is inversely tapered along the coupler. The mode overlap at the chip facet is studied using a vectorial 2D mode solver and the mode transformation along the coupler is studied by 3D Finite-Difference Time-Domain simulations. The couplers are optimized for operating with transverse electric (TE) polarization and the operating wavelength is centered at 1.55 μm.
Factors Affecting Determination of Platelet Monoamine Oxidase Activity (1980)

Platelet monoamine oxidase (MAO) activity has been reported to be significantly decreased in chronic schizophrenia, but this finding is still quite controversial. Some of the variance between different studies may be due to differences in assay procedures. We have examined the effects of platelet count and platelet pellet protein determinations on assay reliability. The platelet count method was found to be somewhat more reliable than the platelet protein method of determing MAO activity. We also examined the effect of centrifugation conditions on platelet MAO activity. Platelets harvested at 100g had significantly higher MAO activity than platelets harvested at 600g. A significantly greater variation in the 600g platelet MAO activity/100g platelet MAO activity ratio was found in psychiatric patients than in control subjects.
Non-Hyperbolic Moveout Correction Of Reflection Seismic Records (1989)

For a horizontally layered earth the exact two-way travel time equation&lt;br&gt;is:&lt;br&gt;T2 = T02 + x2 / V2 + C3 X4 + C4 X5 + - - - (1).&lt;br&gt;(Taner and Koehler, 1969).&lt;br&gt;T = two-way time from source to receiver; T0 = vertical two-way time;&lt;br&gt;X = source to receiver distance (offset); V, c3, c4, = constants&lt;br&gt;which depend on the interval velocities (V1) thicknesses of the&lt;br&gt;individual layers (Fig. 1).&lt;br&gt;The terms in X4 and X5 are small for low and medium angles of&lt;br&gt;incidence, and these terms are normally ignored in seimic processing.
Frameless Stereotactic Imaging Techniques in Minimally Invasive Spinal Surgery (2005)

Frameless stereotactic imaging is widely used in intracranial neurosurgical procedures to locate pathology precisely and decrease the morbidity of traditional open exploratory procedures. However, the clinical application of computer-assisted image-guided spinal surgery has not been widely accepted owing to the time-consuming and arduous nature of maintaining accurate registration coordinates. Frameless spinal stereotaxy is an evolving adjunct to the surgeon’s anatomical knowledge and skill. Newer technology involving intraoperative real-time image acquisition and user-friendly instruments will undoubtedly improve the popularity of this technology in complex spinal procedures. Currently, computer image-guided spinal surgery is used for the placement of pedicle screws; transarticular C1–C2 fixation; transoral odontoid resection; anterior cervical corpectomies; and, most recently, in endoscopic spinal surgery.
Fundamental properties of local anesthetics. I. The dependence of lidocaine's ionization and octanol:buffer partitioning on solvent and temperature. (1987)

The protonation equilibrium and hydrophobic character of lidocaine were characterized by its pKa and the octanol:buffer partition coefficients of the charged (P+) and neutral (Po) drug species. These measurements were accomplished by ultraviolet spectrophotometry of pure lidocaine HCl solutions at different temperatures, ionic strengths, and buffer concentrations. Corroboration of the pKa determination by the potentiometric method and of the partition coefficients by gas chromatography validated the general application of the spectrophotometric technique. The pKa increased with decreasing temperature (7.61 +/- 0.06 at 36 degrees C; 7.94 +/- 0.04 at 26 degrees C, in water; mean +/- SD), increasing ionic strength (8.06 +/- 0.02 at 26 degrees C in 0.165 M NaCl) and increasing buffer capacity (8.28 +/- 0.06 at 25 degrees C in 0.15 M NaCl + 20 mM buffer). Octanol:buffer partition coefficients for both the protonated and the neutral species (expressed as mole fractions) increased upon warning: 0.55 +/- 0.04 and 2666 +/- 202, respectively, at 25 degrees C, and 0.75 +/- 0.09 and 3210 +/- 272, respectively, at 36 degrees C. Ionic strength and buffer concentration had no significant effect on either P value. The increase in pKa at lower temperatures coupled with the decreased partition coefficients resulted in a nearly constant concentration of the protonated species in octanol as the system was cooled, whereas the concentration of the neutral species fell by more than 80%. This finding may explain the large increase in the impulse blocking potency of lidocaine observed upon nerve cooling, if the protonated anesthetic species is the more active form of the drug competing with the neutral species for a common binding site.
Pharmacokinetic and Metabolic Studies on Propafenone in Volunteers (1983)

Knowledge of the pharmacokinetic and metabolic behavior of propafenone in humans has been limited mainly by difficulties in analysis and in using radioactively labeled substances. In earlier studies by Wiebringhaus, Keller, and Blanke et al. in Düsseldorf, Berlin, and Göttingen and in our research center in Ludwigshafen, the method used allowed sufficiently precise determinations only above a concentration of 200 ng/ml, which left some uncertainty about the selectivity of the method and the process of elimination, especially regarding the terminal elimination phase.
A Modified Protocol to Maximize Differentiation of Human Preadipocytes and Improve Metabolic Phenotypes (2012)

Adipose stromal cells proliferate and differentiate into adipocytes, providing a valuable model system for studies of adipocyte biology. We compared differentiation protocols for human preadipocytes and report on their metabolic phenotypes. By simply prolonging the adipogenic induction period from the first 3 to 7 days, the proportion of cells acquiring adipocyte morphology increased from 30-70% to over 80% in human subcutaneous preadipocytes (passages 5-6). These morphological changes were accompanied by increases in the adipogenic marker expression and improved adipocyte metabolic phenotypes: enhanced responses to β-adrenergically stimulated lipolysis and to insulin-stimulated glucose metabolism into triglyceride (TG). Confirming previous studies, fetal bovine serum (FBS) dose-dependently inhibited adipogenesis. However, in subcutaneous preadipocytes that differentiate well (donor-dependant high capacity and subcultured fewer than two times), the use of 7d-induction protocols in both 3% FBS and serum-free conditions allowed >80% differentiation. Responsiveness to β-adrenergically stimulated lipolysis was lower in 3% FBS. Rates of insulin-stimulated glucose uptake were higher in adipocytes differentiated with 3% FBS, whereas the sensitivity to insulin was almost identical between the two groups. In summary, extending the length of the induction period in adipogenic cocktail improves the degree of differentiation and responses to key metabolic hormones. This protocol permits functional analysis of metabolic phenotypes in valuable primary human adipocyte cultures through multiple passages.
A New Modification of Two-Stage FlexorTendon Reconstruction (2006)

A new modification of 2-stage flexor tendon reconstruction is described. This new modification includes the utilization of the insertion of the flexor digitorum profundus tendon to develop a distal tunnel for initial placement of the silicon rod at the first stage and subsequent placement of the tendon graft at the second stage. This allows a more distal attachment of the tendon graft at the second stage of the reconstruction, to maximize tendon excursion and minimize adhesions to the volar plate of the distal interphalangeal joint. Therefore, this new modification offers better distal interphalangeal joint function and ease of second stage distal tendon graft attachment.
Inductive conductance measurements in two-dimensional superconducting systems (1989)

A two-coil mutual-inductance technique for measuring the complex ac response of a two-dimensional (2-D) superconductor to a weak ac magnetic field is described. Analytical and numerical methods are presented which allow extraction of the complex ac conductance of the superconductor from the signal voltage induced in the detection coil by the screening currents flowing in the sample. The method is illustrated by measurements of the ac conductance of a square network of aluminum wires from which the penetration depths of both the network and (granular) aluminum are deduced. It is shown that the method provides a powerful tool to observe characteristic features associated with critical phenomena in 2-D superconducting systems.

The fate of silver nanoparticles in authentic human saliva (2018)

The physicochemical properties of silver nanoparticles (AgNPs) in human whole saliva are investigated herein. In authentic saliva samples, AgNPs exhibit a great stability with over 70% of the nanomaterial remaining intact after a 24-h incubation in the presence of ∼0.3 mM dissolved oxygen. The small loss of AgNPs from the saliva sample has been demonstrated to be a result of two processes: agglomeration/aggregation (not involving oxygen) and oxidative dissolution of AgNPs (assisted by oxygen). In authentic saliva, AgNPs are also shown to be more inert both chemically (silver oxidative dissolution) and electrochemically (electron transfer at an electrode) than in synthetic saliva or aqueous electrolytes. The results thus predict based on the chemical persistence (over a 24-h study) of AgNPs in saliva and hence the minimal release of hazardous Ag<sup>+</sup> and reactive oxygen species that the AgNPs are less likely to cause serious harm to the oral cavity but this persistence may enable their transport to other environments.
Cell Lineage Analysis of Mouse Prostate Carcinogenesis (2013)

Abstract : Defining the origin of prostate cancer cells is fundamentally important and will guide future research to focus on cells from which prostate cancer cells are derived. Prostate cancer is thought to be derived from luminal epithelial cells in the prostate, because a hallmark of prostate cancer is the loss of basal epithelial cells and prostate cancer cells exhibit a luminal epithelial cell phenotype including the expression of AR and PSA. However, the luminal origin of prostate cancer has been challenged by a number of recent publications. This project will determine whether prostate cancer cells are derived from luminal or basal epithelial cells in an EAF2-/-; PTEN+/- mouse model, and determine whether luminal-derived prostate cancer cells behave differently from basal-derived prostate cancer cells. In the last year of the funding period, we have generated 1 breeding pair (consisting of 1 male and 1 female) of PSA-CreERT2; R26RmT/mG;EAF2+/-;PTEN+/- mice for Specific Aim 1. Also, we have obtained CK14-CreERT2 mice and began breeding to generate CK14-CreERT2; R26RmT/mG;EAF2-/-;PTEN+/- mice for Specific Aim 2.

Effect of Structure of Functionalizing Molecules on the Inter‐Macromolecular Reactions and Blending of Poly(ethylene‐co‐propylene) (EPM) with Poly(6‐aminohexanoic Acid) (PA6) (2006)

Abstract Two different functionalizing systems, i.e. , monohexadecyl maleate (= hexadecyl hydrogen (2 Z )‐but‐2‐enedioate) in the presence of dicumyl peroxide (= bis(1‐methyl‐1‐phenylethyl) peroxide) or 4‐carboxybenzenesulfonazide (= 4‐(azidosulfonyl)benzoic acid), were used in distinct experiments to perform in a one‐step procedure the formation of a EPM–PA6 graft copolymer, necessary to obtain a compatibilized blend, from a molten mixture of ethylene–propylene copolymer (EPM) and polyamide 6 (PA6). The characterization of the graft polymer by selective solvent extraction of the blends and the subsequent IR and NMR analysis of the various fractions established the occurrence of functionalization reactions preferentially onto the polyolefin with both reagents. Also the formation in good yield of graft copolymers at the phases interface was observed. Moreover, the morphology and thermal characterizations of the blends by means of SEM and DSC analyses were used to evaluate the compatibilization extent in comparison with blends obtained by the conventional two‐step procedure or by the one‐step procedure with commercial maleic acid derivatives.
TRIM5 Retroviral Restriction Activity Correlates with the Ability To Induce Innate Immune Signaling (2015)

The importance of retroviruses for the evolution of susceptible host organisms cannot be overestimated. Eight percent of the human genome is retrovirus sequence, fixed in the germ line during past infection. Understanding how metazoa protect their genomes from mutagenic retrovirus infection is therefore of fundamental importance to biology. TRIM5 is a cellular protein that protects host genome integrity by disrupting the retroviral capsid as it transports viral nucleic acid to the host cell nucleus. Previous data suggest that innate immune signaling contributes to TRIM5-mediated restriction. Here, we show that activation of innate immune signaling is conserved among primate and carnivore TRIM5 orthologues and among 3 of the 7 mouse Trim5 homologues and that such activity is required for TRIM5-mediated restriction activity.
Use of Multiple Biomarkers to Improve the Prediction of Death from Cardiovascular Causes (2008)

Our data suggest that in elderly men with or without prevalent cardiovascular disease, the simultaneous addition of several biomarkers of cardiovascular and renal abnormalities substantially improves the risk stratification for death from cardiovascular causes beyond that of a model that is based only on established risk factors.
