Synchrotron Radiation Analyses of Domain Switching and Lattice Strain Behaviors for Ferroelectric (Bi0.5Na0.5)TiO3Single Crystals under Electric Fields (2013)

Abstract The behaviors of intrinsic lattice strain and polarization switching under electric fields (E) have been investigated for ferroelectric (Bi0.5Na0.5)TiO3 [BNT] with rhombohedral structure using high-energy synchrotron radiation. Single crystal X-ray diffraction analyses revealed that the lattice parameters exhibited a linear response to unipolar E along the polar axis (pseudocubic <111>: <111>c). The intrinsic piezoelectric constants d 33 and d 31 of single-domain BNT crystals were evaluated to be 37 ± 5 pm/V and −22 ± 5 pm/V, respectively. Diffraction spots under bipolar E indicated that the reversal of spontaneous polarization (P s) along <111>c was achieved via non-180° (71° and/or 109°) P s rotation.

The cardiac safety test protocol was based on the rigorous safety protocol required by the Office of Naval Research for government funded basic science oriented research program.
Preparation of 4‐[11C]methylmetaraminol, a potential PET tracer for assessment of myocardial sympathetic innervation (2002)

Abstract The false adrenergic neurotransmitter [ 11 C] meta ‐hydroxyephedrine ([ 11 C]HED) is currently the PET tracer of choice for assessment of myocardial sympathetic innervation. The molecule is metabolised in the 4‐position of the aromatic ring. The resulting radiolabelled metabolites need to be measured in order to obtain an arterial input function. Our aim was the development of a PET tracer with an increased metabolic stability relative to [ 11 C]HED. We selected 4‐methylmetaraminol as a candidate molecule for radiolabelling with 11 C ( t 1/2 20.4 min). Our radiosynthetic approach towards 4‐[ 11 C]methylmetaraminol involved a palladium‐catalyzed cross‐coupling reaction of a protected 4‐trimethylstannyl derivative of metaraminol with [ 11 C]methyl iodide followed by removal of the protective groups. 4‐[ 11 C]methylmetaraminol was obtained in a final decay‐corrected radiochemical yield of 20–25% within a synthesis time of 60–80 min. The specific radioactivity at the end of the synthesis ranged from 18–37 to GBq/μmol. The unlabelled reference molecule, 4‐methylmetaraminol, was prepared in a 5‐step synthesis starting from metaraminol. A biological evaluation of 4‐[ 11 C]methylmetaraminol is in progress and the results will be reported elsewhere. Copyright © 2002 John Wiley &amp; Sons, Ltd.
A New Remote Camera Work System for Teleconference Using a Combination of Omni-Directional and Network Controlled Cameras (2008)

As advent of communication network and multimedia processing technologies, various video conference systems to smoothly communicate each other between remote sites using with high quality audio and video have been developed. However, since those video conference systems usually use conventional cameras which only capture the objective images in one direction with narrow area, wide area such as 360 degree of surround direction cannot be captured. In this paper, we introduce a new teleconference system so called Telegnosis in which omni-directional camera and PTZ (Pan/Tilt/Zoom) are combined. While the omni-directional camera capture 360 degree of surrounding images, the PTZ camera captures more detail images specified by the users in omni-directional panorama images by pan, tilt and zoom operations. Using multiple Telegnosis systems, more flexible and dynamic video conference system can be realized for new application fields.
A Novel Approach to Collecting Satellite Cells From Adult Skeletal Muscles on the Basis of Their Stress Tolerance (2013)

Stem cells are generally collected using flow cytometry, but this method is not applicable when the cell surface marker is not well determined. Satellite cells, which are skeletal muscle stem cells, have the ability to regenerate damaged muscles and are expected to be applicable for treatment of muscle degeneration. Although the transcription factor Pax7 is a known specific marker of satellite cells, it is not located on the cell surface and therefore flow cytometry is not directly applicable. In the present study, we turned our attention to the stress tolerance of adult stem cells, and we propose long-term trypsin incubation (LTT) as a novel approach to collecting satellite cells from mouse and human skeletal muscles. LTT led to a remarkable increase in the ratio of Pax7(+) cells that retain normal myogenic stem cell function. In particular, human Pax7(+) cells made up approximately 30% of primary cultured cells, whereas after LTT, the ratio of Pax7(+) cells increased up to ∼80%, and the ratio of Pax7(+) and/or MyoD(+) myogenic cells increased to ∼95%. Once transplanted, LTT-treated cells contributed to subsequent muscle regeneration following repetitive muscle damage without additional cell transplantation. The stress tolerance of Pax7(+) cells is related to heat shock protein 27 and αB-crystallin, members of the small heat shock protein family. This approach, based on the stress resistance of adult stem cells, is a safe and inexpensive method of efficiently collecting human satellite cells and may also be used for collecting other tissue stem cells whose surface marker is unknown.
Will We Soon Be Fueling our Automobiles with Ammonia–Borane? (2007)

The B all and N all? Ammonia–borane (AB, H3NBH3) contains 19.6 weight % H, and is one of the materials currently being examined as a possible H2 source for use in fuel cells to power automobiles. Challenges for this technology are noted, and recent advances, especially in the development of both transition-metal and acid catalysts which promote H2 release from AB under mild conditions, are highlighted.
Rate-Optimizing Compilers for Continuously Non-Malleable Codes. (2019)

We study the rate of so-called continuously non-malleable codes, which allow to encode a message in such a way that (possibly adaptive) continuous tampering attacks on the codeword yield a decoded value that is unrelated to the original message. Our results are as follows:


For the case of bit-wise independent tampering, we establish the existence of rate-one continuously non-malleable codes with information-theoretic security, in the plain model.


For the case of split-state tampering, we establish the existence of rate-one continuously non-malleable codes with computational security, in the (non-programmable) random oracle model. We further exhibit a rate-1/2 code and a rate-one code in the common reference string model, but the latter only withstands non-adaptive tampering. It is well known that computational security is inherent for achieving continuous non-malleability in the split-state model (even in the presence of non-adaptive tampering).

Noninductive Current Generation in NSTX using Coaxial Helicity Injection (2001)

Coaxial Helicity Injection (CHI) on the National Spherical Torus Experiment (NSTX) has produced 240 kA of toroidal current without the use of the central solenoid. Values of the current multiplication ratio (CHI produced toroidal current/injector current) up to 10 were obtained, in agreement with predictions. The discharges which lasted for up to 200 ms, limited only by the programmed waveform, are more than an order of magnitude longer in duration that any CHI discharges previously produced in a Spheromak or a Spherical Torus (ST).
The Effects of Therapeutic Duration of Combined Antiplatelets, Aspirin and Ticlopidine, on Coronary Stent Restenosis (1998)

Background:One of most important mechanisms of coronary stent restenosis is neointimal hyperplasia. Although the process of neointima formation is not fully understood, a special role has been advocated for adherent platelets. Previous studies have shown a clear benefit with combined antiplatelet therapy such as aspirin plus ticlopidine in reducing the rate of thrombotic occlusions of stented vessels. The purpose of this study was to evaluate the effects of duration of antiplatelet regimens on coronary stent restenosis. Methods:After successful placement of coronary artery stents in 222 patients, we performed follow-up coronary angiograms in 99 patients(42.3%. Forty-six patients were randomly assigned to receive aspirin and ticlopidine for four weeks(Group Ⅰ:54±9 years:M 38, F 8 and 48 patients for 6 months(Group Ⅱ:58±8 years:M 38, F 10. Results:There were no significant differences in clinical and procedural variables or coronary lesion characteristics before and after stenting. At 6 months after stenting, minimal luminal diameter was 2.16±0.93mm in Group Ⅰ and 2.04±1.07mm in Group Ⅱ(p=0.57. Late lumen loss was 0.80±1.07mm in Group Ⅰ and 0.92±1.11mm(p=0.58 in Group Ⅱ. The stent restenosis rate of Group Ⅰ at 28.3% and that of Group Ⅱ at 29.2% were not statistically significant between the two groups(p=0.92.

Lectin-binding pattern in human non-Hodgkin lymphoma xenografts. (1989)

The glycan profile of cell surface proteins has been studied on three human non-Hodgkin lymphoma xenografts of B-cell origin using a panel of biotinylated lectins. All three lines showed a more heterogeneous lectin-binding pattern than normal peripherial blood lymphocytes (PBLs) involving both the inner core and antenna part of the glycans. The conservative inner core (N-N-acetylchitobiose and oligomannose) was similar but fucosylated to various extents in the different lymphomas. The structure of the antennae of PBLs was characterized by glcNac-gal and galNac-gal-Sa sequences, while in lymphomas additional asialo as well as sialylated galNac containing antennae have been identified. This study suggests that NHLs sharing many immunophenotypic features show intertumoral differences in their lectin-binding pattern.
Optimization of Gaussian surface calculations and extension to solvent-accessible surface areas (1999)

We explored the use of several breadth-first and depth-first algorithms for the computation of Gaussian atomic and molecular surface areas. Our results for whole-molecule van der Waals surface areas (vdWSAs) were 10 times more accurate in relative error, relative to actual hard-sphere areas, than those reported by earlier workers. We were also able to extend the method to the computation of solvent-accessible surface areas (SASAs). This was made possible by an appropriate combination of algorithms, parameters, and preprocessing steps. For united-atom 3app, a 2366-atom protein, we obtained an average absolute atomic error of 1.16 Å2 with respect to the hard-sphere atomic SASA results in 7 s of CPU time on an R10000/194 MHz processor. Speed and accuracy were both optimized for SASA by the use of neighbor-list reduction (NLR), buried-atom elimination (BAE), and a depth-first search of the tree of atomic intersections. Accuracy was further optimized by the application of atom type specific parameters to the raw Gaussian results. ©1999 John Wiley & Sons, Inc. J Comput Chem 20: 688–703, 1999
Mixed ancestry from wild and domestic lineages contributes to the rapid expansion of invasive feral swine (2020)

Invasive alien species are a significant threat to both economic and ecological systems. Identifying the processes that give rise to invasive populations is essential for implementing effective control strategies. We conducted an ancestry analysis of invasive feral swine (Sus scrofa, Linnaeus, 1758), a highly destructive ungulate that is widely distributed throughout the contiguous United States, to describe introduction pathways, sources of newly emergent populations and processes contributing to an ongoing invasion. Comparisons of high-density single nucleotide polymorphism genotypes for 6,566 invasive feral swine to a comprehensive reference set of S. scrofa revealed that the vast majority of feral swine were of mixed ancestry, with dominant genetic associations to Western heritage breeds of domestic pig and European populations of wild boar. Further, the rapid expansion of invasive feral swine over the past 30 years was attributable to secondary introductions from established populations of admixed ancestry as opposed to direct introductions of domestic breeds or wild boar. Spatially widespread genetic associations of invasive feral swine to European wild boar deviated strongly from historical S. scrofa introduction pressure, which was largely restricted to domestic pigs with infrequent, localized wild boar releases. The deviation between historical introduction pressure and contemporary genetic ancestry suggests wild boar-hybridization may contribute to differential fitness in the environment and heightened invasive potential for individuals of admixed domestic pig-wild boar ancestry.
Making polymeric membranes antifouling via “grafting from” polymerization of zwitterions (2014)

ABSTRACT Protein‐fouling of membranes has negative effects on the wide applications of membrane materials, such as poly(vinylidene fluoride) (PVDF), poly(ether sulfone) (PES)/polysulfone (PSf). Zwitterionic materials have recently been used and identified from high throughput screens of large libraries of monomers to modify membranes due to their stable anti‐protein‐fouling properties. “Grafting from” polymerization is a technique involving monomers that are polymerized using an initiation reaction on the membrane surface. It is regarded as a simple, useful, and versatile modification approach to increase the anti‐fouling properties of a membrane. This strategy provides controllable introduction of graft chains with a high density and a long‐term chemical stability due to covalent attachment of graft chains. Graft density, chemistry, chain length, and conformation are all important parameters that need to be considered. This article presents a mini‐review of recent progress on the “grafting from” polymerization of zwitterionic monomers on the surfaces of PVDF and PES/PSf membranes, including an introduction of zwitterions and methods of graft polymerization. Various approaches such as free radical graft polymerization, photo‐induced graft polymerization, and plasma‐induced graft polymerization were compared based on uniformity and amount of grafted zwitterionic polymer, relative flux of modified membranes, simplicity and environment pollution of operation, and cost of technique. The application of different approaches and the performance of poly(zwitterion)‐grafted PVDF and PES/PSf membranes are summarized according to recent research. © 2014 Wiley Periodicals, Inc. J. Appl.

Robust parametrization for non-destructive evaluation of composites using ultrasonic signals (2011)

Anticipating and characterizing damages in layered carbon fiber-reinforced polymers is a challenging problem. Non-destructive evaluation using ultrasonic signals is a well-established method to obtain physically relevant parameters to characterize damages in isotropic homogeneous materials. However, ultrasonic signals obtained from composites require special care in signal interpretation due to their structural complexity. In this paper, some enhancements on the interpretation are done by adapting classical parametrization techniques to extract relevant features from the ultrasonic signals. Thus, a cepstral-based feature extractor is firstly designed and optimized by using a classification system based on cepstral distances. Then, this feature extractor is applied in an analysis-by-synthesis scheme which, by using a numerical model of the specimen, infers the values of the damage parameters.
Two-way cross-protection between West Nile and Japanese encephalitis viruses in bonnet macaques. (1992)

Cross-protection between Japanese encephalitis (JE) and West Nile (WN) viruses was tested in bonnet macaques (Macaca radiata) immunized either with JE virus (JEV) or WN virus (WNV). JEV immunized monkeys were challenged by intranasal (i.n.) route with WNV and vice versa. Four control unimmunized monkeys were similarly infected either with WNV or JEV. Two of three control monkeys infected with WNV, developed paralysis followed by death. Virus was recovered from the central nervous system (CNS) of the both dead control monkeys and the histopathological examination of CNS revealed changes suggestive of viral encephalitis. The control monkey infected with JEV developed encephalitis and the virus was recovered from the blood and CNS. All the 3 JEV-immunized monkeys withstood WNV challenge, whereas only 2 of the 5 WNV immunized monkeys withstood the challenge with JEV. Out of 3 WNV-immunized monkeys surviving challenge with JEV, 2 revealed symptoms suggestive of mild encephalitis followed by complete recovery. The third monkey died on the 60th day post-infection (p.i.) without any symptoms and virus was recovered only from the olfactory lobe. These studies indicate that the immunization with JEV protects the bonnet macaques against WNV, whereas the WNV immunization only reduces the severity of the disease due to JEV.
HCV‐Related Immunocytoma and Type II Mixed Cryoglobulinemia‐Associated Autoantigens (2007)

Hepatitis C virus (HCV) is a hepatotropic virus causing hepatocellular damage and chronic liver inflammation that progressively can lead to cirrhosis and hepatocellular carcinoma (HCC). HCV is also lymphotropic, as demonstrated by its capacity to replicate in lymphocytes, by the recurrent detection of organ- and non-organ-specific autoantibodies in HCV-infected patients, and by the strong association found between HCV infection and type II mixed cryoglobulinemic syndrome (MC-II). Moreover, accumulating data ascribe an etiopathogenetic role in the development of B cell non-Hodgkin's lymphomas (NHL) to HCV. All these findings account for the profound effect of HCV infection in the host's immune system. The unique virus-host interactions that culminate in the generation and sustained production of autoantibodies and cryoglobulins have not been delineated. It appears that chronic antigenic stimulation could cause the emergence of specific B cell clones that produce cryoglobulins; moreover, B cell activation and/or deregulation could originate as a result of HCV binding to CD81 tetraspanin or as a consequence of its ability to replicate in B cells. In a previous study we demonstrated that, in MC-II HCV-positive patients, cryoprecipitated monoclonal IgMs, and B cell receptors (BCR) of overexpanded B cell clones share the same combinatory region. Moreover, these IgMs were reactive against both the Fc region of human IgG and the HCV-NS3 antigen. NS3 and Fc epitopes have been idengified by epitope excision approach. One of the idengified NS3 epitopes has been used to immunize a mouse and the monoclonal antibody obtained showed the same cross-reactivity as patients' IgMs. The characterization of antigenic specificity of this antibody may be useful to idengify antigens that can stimulate B cell proliferation in HCV-infected individuals.

An Inhibition Elisa for the Quantification of Collagens Type I and Type II in Cyanogen Bromide-Digested Tissues Using Fragment-Directed Antibodies (1990)

The quantification of connective tissue components in small tissue samples is of great importance for the examination of drug-induced changes in the development of the mammalian embryo. An inhibition-ELISA for the quantification of collagens type I and type II in CNBr-digested tissue samples was developed. Fragments of type I collagen were produced by CNBr-cleavage of the pure collagen and partially purified by gel filtration chromatography. A mixture of fragments was used to immunize rabbits. Antisera with highest titres were absorbed with immobilized fibronectin and collagens type II, III, V and I. The eluted antibodies exhibited specificity for alpha 2(I)-CB4, exclusively. These antibodies, as well as the previously described antibodies with specificity for alpha 1(II)-CB8, were used for the development of an inhibition-ELISA. The sensitivity of the assay is 0.3 micrograms/ml for collagen I and 3 micrograms/ml for collagen II. To evaluate the value and practicability of the ELISA we have estimated the amounts of both collagens in biochemically well characterized tissues (skin, aorta, chondrosarcoma) and have performed an initial determination in mouse embryos.
