A systematic review of the survival of implants in bone sites augmented with barrier membranes (guided bone regeneration) in partially edentulous patients (2002)

The aim of the present systematic review was to assess the survival of implants in regenerated bone applying the method of guided bone regeneration (GBR) compared with the survival of implants in non-regenerated bone. Studies to be included in this review needed to provide at least 12-month results following prosthetic reconstruction of titanium implants in bone regenerated by GBR with or without membrane supporting materials. The outcome measures were implant survival described as presence of implant, implant success (according to the criteria in the respective study), absence of clinical implant mobility, absence of implant fracture, absence of progressive peri-implant crestal bone loss as assessed on radiographs without clinical signs of peri-implant infection, absence of peri-implant infection with suppuration. A MEDLINE search and a hand search of relevant scientific journals were conducted including studies from the year 1990 to May 2001. A total of 11 studies could be identified fulfilling the inclusion criteria. All studies except two had the characteristics of case series or cross-sectional surveys. The two different studies had both test and control implants included in their analysis and qualified as controlled clinical trials. Cumulative success or survival rates, respectively, for implants in regenerated bone ranged from 100% after 5 years to 79.4% after 5 years of function. Regarding survival data, no significant differences were found in the controlled clinical trials between implants in regenerated compared to implants in non-regenerated bone. Within the limits of this systematic review characterized by second and third levels of evidence, the following conclusions can be drawn: The survival rate of implants placed into sites with regenerated/augmented bone using barrier membranes varied between 79% and 100% with the majority of studies indicating more than 90% after at least one year of function. The survival rates obtained in the present systematic review are similar to those generally reported for implants placed conventionally into sites without the need for bone augmentation.
Langmuir Films of Asphaltene Model Compounds and Their Fluorescent Properties (2008)

The relationship between the physicochemical properties of asphaltenes and asphaltene structure is an issue of increasing focus. Surface pressure-area isotherms of asphaltene model compounds have been investigated to gain more knowledge of their arrangement at an aqueous surface. Variations in interfacial activity have been correlated to proposed arrangements. The presence of a carboxylic acid has shown to be crucial for their interfacial activity and film properties. The acid group directs the molecules normal to the surface, forming a stable monolayer film. The high stability was absent when no acidic groups were present. Fluorescence spectra of deposited Langmuir-Blodgett films showed only the presence of the excimer emission for thin films of acidic model compounds, indicating a close face-to-face arrangement of the molecules. Time-correlated single photon counting (TCSPC) of the model compounds in toluene indicated the presence of aggregates for two of four compounds at low concentrations. However, a sudden drop of interfacial tension observed could not be correlated to the aggregation. Instead, aggregation induced by addition of a "poor" solvent showed decreased interfacial activity when aggregated due to decrease of monomers in bulk. The findings regarding these asphaltene model compounds and their structural differences show the great effect an acidic group has on their physicochemical properties.
Charisma, Conductors, and the Affective Communication Test (2011)

The following study analyzed results of ensemble conductors of the Big-10, Big-12, and Pac-10 athletic conferences (N = 96) taking the Affective Communication Test (ACT) of nonverbal expressivity or charisma. Results indicate that conductors fall into two ‘clusters ’ of charisma – those that appear to be lower than the general population norm and those that score significantly (p &lt;.01) higher than the norm. Further analyses revealed a trend for men to score higher on the ACT than women but no differences in charisma scores between conductors of choirs, orchestras, and wind bands. There also appears to be a weak, yet significant, trend (r =.28, p &lt;.01) for conductors with higher charisma to believe more strongly in the importance of a conductor’s charisma.

Convex Channel Design for Improved Capacitorless DRAM Retention Time (2009)

A convex channel surface with Si <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.8</sub> Ge <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.2</sub> is proposed to enhance the retention time of a capacitorless DRAM generation 2 type of capacitorless DRAM cell. This structure provides a physical well together with an electrostatic barrier to more effectively store holes and thereby achieve larger sensing margin as well as retention time. The advantages of this new cell design as compared with the planar cell design are assessed via two-dimensional device simulations. The results indicate that the convex heterojunction channel design is very promising for future capacitorless DRAM.

Syntheses of Deoxynupharidine Derivatives (1971)

Reaction of deoxynupharidine (I) with acetylchloride, nitric acid, and p-nitro benzene-diazonium chloride gave 5'-acetyl-(II), 5'-nitro- and 5'-(4-nitrophenyl)-derivatives, respectively, but not 2'-substituted products. Heating of II in aqueous ammonia containing ammonium chloride afforded 1, 7-dimethyl-4-(3-hydroxy-2-methyl-5-pyridyl)-octahydro-quinolizine (IX).
Substrate-Integrated Waveguide Dual-Mode Dual-Band Bandpass Filters With Widely Controllable Bandwidth Ratios (2017)

A realization method, named the design parameters ratio technique, of substrate-integrated waveguide (SIW) dualmode dual-band bandpass filters (DM-DBBPFs) with widely controllable bandwidth ratios is presented when TE <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">101</sub> and TE <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">201</sub> modes in substrate-integrated rectangular cavities are exploited to dominate the first and second passbands, respectively.

Consequently, the fractional bandwidths (FBWs) of the two passbands can be allocated flexibly over a wide range of ratios, typically with the FBW ratio of 0.2-1.5. Three SIW DM-DBBPFs including a thirdorder direct-coupled one operating at 12 and 16 GHz with the identical absolute bandwidths, a third-order cross-coupled one operating at 12 and 15 GHz with the same FBWs, and a fourth-order cross-coupled one operating at 12 and 17 GHz with the FBW ratio of 0.6 are designed and fabricated to demonstrate the method.

Transfer of AlGaN/GaN RF-devices onto diamond substrates via van der Waals bonding (2018)

Abstract We present a novel bonding process for gallium nitride-based electronic devices on diamond heat spreaders. In the proposed technology, GaN devices are transferred from silicon (Si) onto single (SCD) and polycrystalline diamond (PCD) substrates by van der Waals bonding. Load-pull measurements on Si and SCD heat spreaders at 3 GHz and 50 V drain bias show comparable power-added-efficiency and output power ( P out ) levels. A thermal analysis of the hybrids was performed by comparison of 2 × 1mm 2 AlGaN/GaN Schottky diodes on Si, PCD, and SCD, which exhibit a homogeneous field in the channel in contrast to gated transistors. Significantly different currents are observed due to the temperature dependent mobility in the 2DEG channel. These measurements are supported by a 3D thermal finite element analysis, which suggests a large impact of our transfer technique on the thermal resistance of these devices. In summary, we show a promising new GaN-on-diamond technology for future high-power, microwave GaN device applications.
Clinicopathological significance of miR‐26, miR‐107, miR‐125b, and miR‐203 in head and neck carcinomas (2018)

These findings suggest that miR-26 and miR-125b may be associated with the progression and metastasis of HNSCC and that miR-203 is associated with a more favorable prognosis.
The catalytic subunit of protein kinase A triggers activation of the type V cyclic GMP-specific phosphodiesterase from guinea-pig lung (1992)

The type V cyclic GMP phosphodiesterase was partially purified from the high-speed supernatant of guinea-pig lung. The isoenzyme displayed linear kinetics for cyclic GMP hydrolysis, with Km = 2.2 +/- 0.2 microM and Vmax. = 1.2 +/- 0.08 nmol/min per mg. The selective type V phosphodiesterase inhibitor Zaprinast inhibited cyclic GMP hydrolysis with IC50 (concn. giving 50% inhibition) = 0.45 +/- 0.08 microM. Isobutylmethylxanthine promoted a 3-fold increase in the binding of cyclic GMP to the isoenzyme. The addition of the catalytic subunit of protein kinase A to an activation cocktail containing the partially purified type V phosphodiesterase resulted in a marked increase in Vmax. for cyclic GMP hydrolysis (approximately 10-fold at 40 units of protein kinase A). We have suggested that protein kinase A triggers phosphorylation of the phosphodiesterase, which results in activation of phosphodiesterase activity. In addition, the sensitivity to inhibition by Zaprinast is severely decreased (the IC50 for inhibition is 7.5 +/- 1.1 microM), suggesting that the potency of phosphodiesterase inhibitors is effected by phosphorylation of the enzyme.
Measurement of Antibody Levels against Region II of the Erythrocyte-Binding Antigen 175 of <i>Plasmodium falciparum</i> in an Area of Malaria Holoendemicity in Western Kenya (2004)

Region II of the 175-kDa erythrocyte-binding antigen (EBA-175RII) of Plasmodium falciparum is functionally important in sialic acid-dependent erythrocyte invasion and is considered a prime target for an invasion-blocking vaccine. The objectives of this study were to (i) determine the prevalence of anti-EBA-175RII antibodies in a naturally exposed population, (ii) determine whether naturally acquired antibodies have a functional role by inhibiting binding of EBA-175RII to erythrocytes, and (iii) determine whether antibodies against EBA-175RII correlate with immunity to clinical malaria. We treated 301 lifelong residents of an area of malaria holoendemicity in western Kenya for malaria, monitored them during a high-transmission season, and identified 33 individuals who were asymptomatic despite parasitemia (clinically immune). We also identified 50 clinically susceptible individuals to serve as controls. These 83 individuals were treated and monitored again during the subsequent low-transmission season. Anti-EBA-175RII antibodies were present in 98.7% of the individuals studied. The antibody levels were relatively stable between the beginning and end of the high-transmission season and correlated with the plasma EBA-175RII erythrocyte-binding-inhibitory activity. There was no difference in anti-EBA-175RII levels or plasma EBA-175RII erythrocyte-binding-inhibitory activity between clinically immune and clinically susceptible groups. However, these parameters were higher in nonparasitemic than in parasitemic individuals at enrollment. These results suggest that although antibodies against EBA-175RII may be effective in suppressing some of the wild parasite strains, EBA-175RII is unlikely to be effective as a monovalent vaccine against malaria, perhaps due to allelic heterogeneity and/or presence of sialic acid-independent strains.
Enhancement of Digital Images using Stochastic Resonance (2005)

In certain non-linear dynamical systems, the addition of noise can assist the detection of a signal. In general, noise is always seen as deteriorating the system performance very effectively and is therefore normally considered as a nuisance. However, in certain non-linear systems including non-linear signal and image processing, the presence of noise can in fact enhance the weak signal strength or the low contrast images. This phenomenon is termed stochastic resonance. In this paper, we present a novel approach for contrast enhancement of low contrast images, which outperforms the other image enhancement techniques. Block diagram of our algorithm for stochastic resonance and derivation of threshold equations to be used in image contrast enhancement is also presented in this paper. The result of this processing yields a contrast- enhanced image with better visualizibility, no blocking artifacts and no other visual distortion like spot in an image. Results of our methods are compared with the enhancement methods based on histogram equalization and wavelet transform.
<i>Fast</i>‐FISH Detection and Semi‐Automated Image Analysis of Numerical Chromosome Aberrations in Hematological Malignancies (1998)

A new fluorescence in situ hybridization (FISH) technique called Fast-FISH in combination with semi-automated image analysis was applied to detect numerical aberrations of chromosomes 8 and 12 in interphase nuclei of peripheral blood lymphocytes and bone marrow cells from patients with acute myelogenous leukemia (AML) and chronic lymphocytic leukemia (CLL). Commercially available alpha-satellite DNA probes specific for the centromere regions of chromosome 8 and chromosome 12, respectively, were used. After application of the Fast-FISH protocol, and microscopic images of the fluorescence-labelled cell nuclei were recorded by the true color CCD camera Kappa CF 15 MC and evaluated quantitatively by computer analysis on a PC. These results were compared to results obtained from the same type of specimens using the same analysis system but with a standard FISH protocol. In addition, automated spot counting after both FISH techniques was compared to visual spot counting after standard FISH. A total number of about 3,000 cell nuclei was evaluated. For quantitative brightness parameters, a good correlation between standard FISH labelling and Fast-FISH was found. Automated spot counting after Fast-FISH coincided within a few percent to automated and visual spot counting after standard FISH. The examples shown indicate the reliability and reproducibility of Fast-FISH and its potential for automatized interphase cell diagnostics of numerical chromosome aberrations. Since the Fast-FISH technique requires a hybridization time as low as 1/20 of established standard FISH techniques, omitting most of the time consuming working steps in the protocol, it may contribute considerably to clinical diagnostics. This may especially be interesting in cases where an accurate result is required within a few hours.
Microbial conversion of DL-2-amino-delta2-thiazoline-4-carboxylic acid to L-cysteine and L-cystine: screening of microorganisms and identification of products (1977)

Microorganisms able to form L-cysteine from DL-2-amino-delta2-thiazoline-4-carboxylic acid (DL-ATC), a chemical intermediate in the synthesis of DL-cysteine, were isolated from soil samples and classified as Pseudomonas sp., Pseudomonas cohaerens, P. desmolytica, and P. ovalis. Thirteen L-cysteine-producing bacteria were also found in among 463 stock cultures representing 37 genera. These were Achromobacter delmarvae. Alcaligenes denitrificans, Bacillus brevis, Brevibacterium flavum, Enterobacter aerogenes, Erwinia carotovora, Escherichia coli, Micrococcus sodonensis, Myocoplana dimorpha, Sarcina lutea, Serratia marcescens, Flavobacterium acidoficum, and Pseudomonas ovalis. In the presence of intact cells of Pseudomonas sp. AJ 3854, 6.1 mg of L-cysteine and/or L-cystine per ml was produced from 10 mg of DL-ATC-3H2O per ml in a molar yield of 100%. This finding suggests that racemization and asymmetric hydrolysis occurred simultaneously in this incubation mixture. After the complete oxidation of cysteine to cystine by aeration in the presence of ferrous ion, crystalline cystine was isolated; its configuration was the L isomer based on data from X-ray diffraction, microbioassay, and optical rotation studies.

CompStor Novos: a low cost yet fast assembly-based variant calling for personal genomes (2018)

Application of assembly methods for personal genome analysis from next generation sequencing data has been limited by the requirement for an expensive supercomputer hardware or long computation times when using ordinary resources. We describe CompStor Novos, achieving supercomputer-class performance in de novo assembly computation time on standard server hardware, based on a tiered-memory algorithm. Run on commercial off-the-shelf servers, Novos assembly is more precise and 10-20 times faster than that of existing assembly algorithms. Furthermore, we integrated Novos into a variant calling pipeline and demonstrate that both compute times and precision of calling point variants and indels compare well with standard alignment-based pipelines. Additionally, assembly eliminates bias in the estimation of allele frequency for indels and naturally enables discovery of breakpoints for structural variants with base pair resolution. Thus, Novos bridges the gap between alignment-based and assembly-based genome analyses. Extension and adaption of its underlying algorithm will help quickly and fully harvest information in sequencing reads for personal genome reconstruction.
Effects of Energetic Polymers on Laser Photothermal Imaging Materials (2000)

The effects of adding a thin layer of an energetic polymer such as nitrocellulose (NC) to laser photothermal imaging media are investigated. Photothermal media are used which are model systems for computer-to-plate or computer-to-press imaging. The media consist of a substrate, a thin absorbing metallic absorbing layer and a silicone rubber imaging layer. An energetic polymer can be added between the substrate and the absorber. With 10 μs duration near-IR exposure pulses, the energetic layer has no discernable effect. With 110 ns imaging pulses, exposed spots in imaging media with energetic underlayers can be more than three times larger. The improvement due to energetic polymers results from confining the hot gas-phase thermochemical decomposition products under the silicone layer, as shown by time-resolved microscopy. The force exerted by the expanding bubble tears the neck of the bubble away from the substrate, increasing the imaged spot size. These rather complicated processes cannot be described by previously used simple exposure threshold models. An exposure parameter is introduced which deals with this problem. In some cases energetic material underlayers can improve the sensitivity of the media by a factor of three. This work is believed to be the first where a substantial sensitivity improvement in laser threshold for photothermal imaging is obtained with energetic polymers.
