A Randomized Trial Comparing Conventional and Endovascular Repair of Abdominal Aortic Aneurysms (2004)

On the basis of the overall results of this trial, endovascular repair is preferable to open repair in patients who have an abdominal aortic aneurysm that is at least 5 cm in diameter. Long-term follow-up is needed to determine whether this advantage is sustained.
Reactions with 1-benzotriazolecarboxylic acid chloride. I. Synthesis of the 2,6-bis(hydroxymethyl)pyridinedicarbamates (1977)

Some 2,6-bis(hydroxymethyl)pyridinedicarbamates VII were synthesized by reaction of pyridinedimethanole (I) with carbamoylazoles II-VI (azole=imidazole, benzimidazole, pyrazole, 1,2,4-triazole, benzotriazole). It is confirmed that this reaction proceed via an intermolecular elimination-addition acyl transfer mechanism including in the first step the formation of an isocyanate. Carbamoylbenzotriazoles Vla-i were prepared by aminolysis of 1-benzot,riazole-' carboxylic acid chloride (VIII) obtained from benzotriazole and phosgene.
Germinal Center Alloantibody Responses Are Mediated Exclusively by Indirect-Pathway CD4 T Follicular Helper Cells (2012)

The durable alloantibody responses that develop in organ transplant patients indicate long-lived plasma cell output from T-dependent germinal centers (GCs), but which of the two pathways of CD4 T cell allorecognition is responsible for generating allospecific T follicular helper cells remains unclear. This was addressed by reconstituting T cell-deficient mice with monoclonal populations of TCR-transgenic CD4 T cells that recognized alloantigen only as conformationally intact protein (direct pathway) or only as self-restricted allopeptide (indirect pathway) and then assessing the alloantibody response to a heart graft. Recipients reconstituted with indirect-pathway CD4 T cells developed long-lasting IgG alloantibody responses, with splenic GCs and allospecific bone marrow plasma cells readily detectable 50 d after heart transplantation. Differentiation of the transferred CD4 T cells into T follicular helper cells was confirmed by follicular localization and by acquisition of signature phenotype. In contrast, IgG alloantibody was not detectable in recipient mice reconstituted with direct-pathway CD4 T cells. Neither prolongation of the response by preventing NK cell killing of donor dendritic cells nor prior immunization to develop CD4 T cell memory altered the inability of the direct pathway to provide allospecific B cell help. CD4 T cell help for GC alloantibody responses is provided exclusively via the indirect-allorecognition pathway.
Effect of Dietary Fiber on Fecal and Urinary Excretion of Trp-P-2 in the Rat (1992)

Dietary fiber and Trp-P-2-containing diet was administered to rats. Fecal excretion of Trp-P-2 administered with fiber was faster than that in the absence of fiber. Fecal excretion of Trp-P-2 was increased by the diet with either 10% crude burdock fiber or 10% cellulose, although the increment of Trp-P-2 in feces was small as compared with the initially administered dose. The dietary fibers tested did not affect the urinary excretion of Trp-P-2. HPLC chromatograms of feces and urine suggested that major components might be metabolites of trp-P-2. Although the addition of dietary fiber increased fecal volume, this increase did not appear to account for the increase of Trp-P-2 excretion.
pH-Dependent Optical Properties of a Poly(phenylene ethynylene) Conjugated Polyampholyte (2010)

A poly(phenylene ethynylene) conjugated polymer (PPE-NMe(3)(+)-COO(-)) containing tetraalkylammonium groups and carboxylate groups has been synthesized by Sonogashira coupling. Due to the presence of the strong cationic and weak anionic pendant units, the polymer undergoes a pH-induced transition from cationic polyelectrolyte to polyampholyte due to deprotonation of the carboxylic acid units in basic solution. Studies of the pH dependence of the polymers' optical properties reveal changes in absorption oscillator strength and fluorescence quantum efficiency that are triggered by the transition from cationic polyelectrolyte to polyampholyte nature. Stern-Volmer fluorescence quenching of PPE-NMe(3)(+)-COO(-) with a negatively charged quencher 1,4,5,8-naphthalenediimide-N,N-bis(methylsulfonate) (NDS) shows that the polymer fluorescence quenching is amplified at low pH where the polymer is a polycation, whereas the quenching efficiency is considerably less at high pH.
Secure access system using signature verification over tablet PC (2007)

Low-cost portable devices capable of capturing signature signals are being increasingly used. Additionally, the social and legal acceptance of the written signature for authentication purposes is opening a range of new applications. We describe a highly versatile and scalable prototype for Web-based secure access using signature verification. The proposed architecture can be easily extended to work with different kinds of sensors and large-scale databases. Several remarks are also given on security and privacy of network-based signature verification
A reliable distributed control algorithm for updating replicated databases (1979)

This paper presents a robust, deadlock-free and distributed control algorithm for consistently updating replicated databases. This algorithm is based on local locking and time stamps on lock tables which permit detection of conflicts among transactions executed at replicated databases. Messages are exchanged in the network whenever a transaction commitment occurs, that is, at the end of every consistent step of local processing. Conflicts among remote transactions are resolved by a roll back procedure. Local restart is based on a journal of locks which provides backup facilities. Performance in terms of the number of messages and volume of control messages of the proposed algorithm is compared with that of the voting and centralized locking algorithms. The results reveal that the proposed distributed control algorithm performs, in most cases, comparably to the centralized locking algorithm and better than the voting algorithm.
Template‐Directed Control of Crystal Morphologies (2007)

Biominerals are characterised by unique morphologies, and it is a long-term synthetic goal to reproduce these synthetically. We here apply a range of templating routes to investigate whether a fascinating category of biominerals, the single crystals with complex forms, can be produced using simple synthetic methods. Macroporous crystals with sponge-like morphologies identical to that of sea urchin skeletal plates were produced on templating with a sponge-like polymer membrane. Similarly, patterning of individual crystal faces was achieved from the micrometer to nanometer scale through crystallisation on colloidal particle monolayers and patterned polymer thin films. These experiments demonstrate the versatility of a templating approach to producing single crystals with unique morphologies.
Luminescence Lifetime Imaging of Oxygen, pH, and Carbon Dioxide Distribution Using Optical Sensors (2000)

We present a modular system for time-resolved two-dimensional luminescence lifetime imaging of planar optical chemical sensors. It is based on a fast, gateable charge-coupled device (CCD) camera without image intensifier and a pulsable light-emitting diode (LED) array as a light source. Software was developed for data acquisition with a maximum of parameter variability and for background suppression. This approach allows the operation of the system even under daylight. Optical sensors showing analyte-specific changes of their luminescence decay time were tested and used for sensing pO 2 , pCO 2 , pH, and temperature. The luminophores employed are either platinum(II)-porphyrins or ruthenium(II)-polypyridyl complexes, contained in polymer films, and can be efficiently excited by blue LEDs. The decay times of the sensor films vary from 70 μs for the Pt(II)-porphyrins to several 100 ns for the Ru(II) complexes. In a typical application, 7 mm-diameter spots of the respective optical sensor films were placed at the bottom of the wells of microtiterplates. Thus, every well represents a separate calibration chamber with an integrated sensor element. Both luminescence intensity-based and time-resolved images of the sensor spots were evaluated and compared. The combination of optical sensor technology with time-resolved imaging allows a determination of the distribution of chemical or physical parameters in heterogeneous systems and is therefore a powerful tool for screening and mapping applications.
Monitoring and measuring instrument design of rf electromagnetic fields for human physical and mental health (2006)

The widely spread of wireless communication and networking have deeply impacted on the daily life environment of Taiwan. Nowadays, the EMF situation is concerned more and more. The protestations against the RF sources arc well seen in daily news. On the other hand, many organizations; such as airport, gas station, hospital,... etc; which as well concern the widespread of EMF. This research developed a system for thoroughly surveying the EMF in the main cities around Taiwan. Our study provides a clear view about the EMF pollution and the exposing dosage of electromagnetic energy of human body on the full environmental EMF circumstance. The acquired data are a valuable reference for the future development of communication infrastructures and public health research about the bioeffect of radiofrequency electromagnetic field.

Neutralizing antibodies to interferon (IFN) α-2a and IFN β-1a or IFN β-1b in MS are not cross-reactive (2000)

Sera from patients with MS treated with recombinant interferon (rIFN) alpha-2a, rIFNbeta-1a, or rIFNbeta-1b were analyzed for cross-reacting neutralizing antibodies (NAB). Because cross-reactivity was not found, switching treatment from rIFNbeta-1a or rIFNbeta-1b to rIFNalpha-2a might provide a secondary treatment response in patients with NAB to rIFNbeta-1a or rIFNbeta-1b. A positive treatment response also might be achieved by switching NAB rIFNalpha-2a-positive patients to rIFNbeta-1a or rIFNbeta-1b.
Any trait or trait-related allele can confer drought tolerance: just design the right drought scenario (2011)

Most traits associated with drought tolerance have a dual effect, positive in very severe scenarios and negative in milder scenarios, or the opposite trend. Their effects also depend on other climatic conditions such as evaporative demand or light, and on management practices. This is the case for processes associated with cell protection and with avoidance, but also for the maintenance of growth or photosynthesis, high water use efficiency, large root systems or reduced abortion rate under water deficit. Therefore, spectacular results obtained in one drought scenario may have a limited interest for improving food security in other geographical areas with water scarcity. The most relevant questions on drought tolerance are probably, 'Does a given allele confer a positive effect on yield in an appreciable proportion of years/scenarios in a given area or target population of environment (TPE)?'; 'In a given site or TPE, what is the trade-off between risk avoidance and maintained performance?'; and 'Will a given allele or trait have an increasingly positive effect with climate change?' Considerable progress has already occurred in drought tolerance. Nevertheless, explicitly associating traits for tolerance to drought scenarios may have profound consequences on the genetic strategies, with a necessary involvement of modelling.
Aligned carbon nanotube–DNA electrochemical sensors (2004)

Single-strand DNA chains were chemically grafted onto aligned carbon nanotube electrodes, leading to novel aligned carbon nanotube-DNA sensors of a high sensitivity and selectivity for probing complementary DNA and target DNA chains of specific sequences.
Stability Differences among Fresh-market Tomato Genotypes: II. Fruit Quality (1989)

Abstract Ten fresh-market tomato ( Lycopersicon esculentum Mill.) genotypes were evaluated for stability of fruit firmness, citric acid, soluble solids, β-carotene and ascorbic acid concentrations, sugar : acid ratio, color, N content, and dry weight when grown in nine environments. Linear relationships between the genotype means for a given trait and the mean for the trait in each environment were used as an indicator of stability. A stable genotype for a given trait was considered to possess a regression coefficient (b 1 ) ⩽ a coefficient of linear determination (r 2 ) > 0.50, a genotype mean above the grand mean (mean of all genotypes), and a nonsignificant deviation from regression mean square (S 2 d). Using these criteria, stability in the nine environments was shown by the fruits of the various cultivars as follows: ‘Flora-Dade’, ‘FTE-12’, and D76I27 for firmness; ‘Castlehy 1035’ and ‘Sunny’ for citric acid; ‘Walter’ for soluble solids concentration; ‘FTE-12’ for ascorbic acid concentration; ‘Hayslip’, ‘Walter’, and ‘Burgis’ for sugar : acid ratio; ‘FTE-12’ and ‘Hayslip’ for β-carotene concentration: ‘Flora-Dade’ and 827115-IBK for color a/b; ‘Castlehy 1035’ and ‘Hayslip’ for dry weight; and ‘Walter’ for N content. Stable genotypes are less sensitive to environmental changes and are more adapted to favorable and unfavorable conditions than unstable genotypes. No genotype was found to be stable for every fruit quality trait in the nine environments. Stability of fruit quality characteristics should be considered in tomato breeding programs to develop genotypes adapted to diverse environmental and management conditions.
Quantitative skeletal muscle ultrasonography in children with suspected neuromuscular disease (2003)

We determined prospectively the diagnostic value of quantitative ultrasonography in detecting neuromuscular disorders in children. Ultrasonographic scans of four muscles were made in 36 children with symptoms or signs suggestive of neuromuscular disease, such as muscle weakness and hypotonia. The muscle thickness, ratio of muscle thickness to subcutaneous fat thickness, and echo intensity were determined in each muscle. The echo intensity was measured using computer-assisted gray-scale analysis. Thirteen of the 36 patients had a neuromuscular disorder (6 a myopathy and 7 a neuropathy). Differentiation between neuromuscular diseases and nonneuromuscular diseases could be made on the basis of echo intensities with a sensitivity of 92%, a specificity of 90%, a positive predictive value of 86%, and a negative predictive value of 95%. We conclude that computer-assisted quantitative analysis of muscle echo intensity is a reliable method to discriminate between neuromuscular and nonneuromuscular diseases in children.

Neurocysticercosis as the main cause of late-onset epilepsy in Mexico (1990)

• We studied 100 consecutive Mexican patients with epilepsy that started after the age of 25 years. All patients underwent clinical evaluation, computed tomography, and electroencephalography; additionally, cerebrospinal fluid analysis was performed in 82 of them. Neurocysticercosis or its sequelae were diagnosed in 50 patients (50%); 36 of these patients had partial seizures, 41 had parenchymal calcifications, and 15 had two or more lesions. Our results are in contrast with those of most studies from countries with a low incidence of neurocysticercosis, where brain tumors, cerebrovascular disease, trauma, and alcoholism are the main causes of tardive epilepsy.

Automated DNA sequencing methods involving polymerase chain reaction. (1989)

Polymerase chain reaction (PCR) as a method for preparing DNA templates has been used for several DNA sequencing applications. An in situ procedure for directly sequencing PCR products by the dideoxy-termination method has been developed by using fluorophore-labeled sequencing primers. Completed sequence reactions were combined and loaded into a single electrophoretic lane of a fluorescence-based DNA sequence analyzer. DNA targets devoid of a universal primer sequence could be sequenced with labeled universal primers by incorporating a universal primer sequence into the PCR product. With this method, the sequence of a 351-bp region in the bacteriophage lambda genome was fully analyzed in a single lane with automatic base identification accuracy of greater than 99%. An unknown sequence, 1.7 kb long, also was sequenced by this procedure, in combination with a "PCR gene walking" strategy. Comparison of the 1110 bases in overlapping sequence data from both strands yielded only two single-base ambiguities. Automated DNA sequence analysis of the highly polymorphic HLA-DQA-1 (alpha) region in the human genome can be performed with this simple methodology. Use of this PCR-sequencing method to analyze DNA extracted from a one-month-old blood sample from an individual who is heterozygous at this locus allowed unambiguous assignment of genotype.
NRMI: Natural and Efficient Middleware (2008)

We present natural remote method invocation (NRMI): a middleware mechanism that provides a fully general implementation of call-by-copy-restore semantics for arbitrary linked data structures, used as parameters in remote procedure calls. Call-by-copy-restore offers a more natural programming model for distributed systems than traditional call-by-copy middleware, enabling remote calls to behave much like local calls. We discuss in depth the effects of calling semantics for middleware, describe when and why NRMI is more convenient to use than standard middleware, and present three implementations of NRMI in distinct settings, showing the generality of the approach.
Interactions between peptides containing nucleobase amino acids and T7 phages displaying <i>S. cerevisiae</i> proteins (2007)

The importance of high-throughput analyses of protein abundances and functions is interestingly increasing in genomic/proteomic studies. In such postgenome sequencing era, a protein-detecting chip, in which a large number of molecules specifically capturing target proteins (capturing agents) such as antibodies, recombinant proteins, and small molecules are arrayed onto solid, wet, or semi-wet substrates, enables comprehensive analysis of proteomes by a single experiment. However, whole proteomes are generally complicated for comprehensive analyses so that alternative approaches to subproteome analysis categorized by protein functions and binding properties (focused proteome) would be effective. Approaching the goal of development of designed peptide chip for protein analysis, diversity increases in peptide structures and validation of target proteins are needed. We herein describe design and synthesis of nucleobase amino acid (NBA)-containing peptides, selection of nucleic acid-related proteins derived from S. cerevisiae, and detection of interactions between NBA-containing peptides and T7 phages displaying proteins by both enzyme-linked immunosorbent assays (ELISA) and label-free anomalous reflection of gold (AR) measurements. Twenty-eight phage clones were obtained by the phage-display method and sequenced. Ten of 28 clones were expected to be nucleic acid-related proteins including initiation factor, TYB protein, ribosomal proteins, elongation factor, ATP synthase subunit, GTP-binding protein, and ribonuclease. Other phage clones encoded several classes of enzymes such as reductase, oxidase, aldolase, metalloprotease, and hexokinase. Both ELISA and AR measurements suggested that the methodology of in vitro selection for recognition of the NBA-containing peptide presented in this study was successfully established. Such a combination of NBA and phage display technologies would be potential to efficiently confirm valuable target proteins binding specifically to capturing agents, to be arrayed onto solid surfaces to develop the designed peptide chip.
Optical head tracking for functional magnetic resonance imaging using structured light (2008)

An accurate motion-tracking technique is needed to compensate for subject motion during functional magnetic resonance imaging (fMRI) procedures. Here, a novel approach to motion metrology is discussed. A structured light pattern specifically coded for digital signal processing is positioned onto a fiduciary of the patient. As the patient undergoes spatial transformations in 6 DoF (degrees of freedom), a high-resolution CCD camera captures successive images for analysis on a computing platform. A high-speed image processing algorithm is used to calculate spatial transformations in a time frame commensurate with patient movements (10-100 ms) and with a precision of at least 0.5 microm for translations and 0.1 deg for rotations.
On Format-Compliant Iterative Encryption of JPEG2000 (2006)

Format-compliant encryption of JPEG2000 has attracted researchers for several years. Most benefits of format-compliant encryption result from the preservation of code-stream features, such as scalability. The possibility of reducing the complexity of encryption and to realize transparent encryption schemes are among the additional features of format-compliant selective encryption. Wu and Deng have proposed a format-compliant iterative encryption scheme for JPEG2000 on a CCP basis. In this paper we discuss whether it is possible to extend this approach to packet bodies and give an exact formula for the expected computational effort. The theoretical results are cross-verified by an experimental survey
