Sorption of radiocobalt and other activation product radionuclides on titanium oxide material CoTreat® (2010)

Abstract CoTreat is a commercial titanate material that is effective for the removal of 60 Co and other activated corrosion product nuclides from nuclear waste effluents. A basic study has been carried out to investigate the uptake mechanism and selectivity of CoTreat material for trace sorption of 54 Mn, 59 Fe, 57 Co, 63 Ni, 65 Zn and 110m Ag. The analyses of the trace sorption isotherms indicate that except for 110m Ag the uptake mechanism for the trace metal ions is surface complex formation. The selectivity of the material for the metal ions studied decreases in the order Fe&gt;Ag&gt;Mn&gt;Co ≈Ni&gt;Zn. Except for Fe, the selectivity thus decreases with the increasing tendency of the cations to hydrolyse.

A Meta-Analysis of the Effects of High-LET Ionizing Radiations in Human Gene Expression (2021)

The use of high linear energy transfer (LET) ionizing radiation (IR) is progressively being incorporated in radiation therapy due to its precise dose localization and high relative biological effectiveness. At the same time, these benefits of particle radiation become a high risk for astronauts in the case of inevitable cosmic radiation exposure. Nonetheless, DNA Damage Response (DDR) activated via complex DNA damage in healthy tissue, occurring from such types of radiation, may be instrumental in the induction of various chronic and late effects. An approach to elucidating the possible underlying mechanisms is studying alterations in gene expression. To this end, we identified differentially expressed genes (DEGs) in high Z and high energy (HZE) particle-, γ-ray- and X-ray-exposed healthy human tissues, utilizing microarray data available in public repositories. Differential gene expression analysis (DGEA) was conducted using the R programming language. Consequently, four separate meta-analyses were conducted, after DEG lists were grouped depending on radiation type, radiation dose and time of collection post-irradiation. To highlight the biological background of each meta-analysis group, functional enrichment analysis and biological network construction were conducted. For HZE particle exposure at 8-24 h post-irradiation, the most interesting finding is the variety of DNA repair mechanisms that were downregulated, a fact that is probably correlated with complex DNA damage formation. Simultaneously, after X-ray exposure during the same hours after irradiation, DNA repair mechanisms continue to take place. Finally, in a further comparison of low- and high-LET radiation effects, the most prominent result is that autophagy mechanisms seem to persist and that adaptive immune induction seems to be present. Such bioinformatics approaches may aid in obtaining an overview of the cellular response to high-LET particles. Understanding these response mechanisms can consequently aid in the development of countermeasures for future space missions and ameliorate heavy ion treatments.
Nested polymerase chain reaction assay for the detection of cytomegalovirus overcomes false positives caused by contamination with fragmented DNA (1990)

The polymerase chain reaction (PCR) technique offers a promising alternative to tissue culture for the rapid and sensitive detection of cytomegalovirus (CMV) infection. However, high levels of background amplification detected in samples containing water but no DNA make interpretation of borderline positive samples extremely difficult and reduce the sensitivity of the assay. The signal from amplification of water or positive samples can be eliminated by DNase treatment, but not by filtration through anisotropic membrane, autoclaving, or ultraviolet irradiation. A lag time of 10 to 12 cycles is observed before the reactions with water will show product formation by liquid hybridization detection. The use of nested PCR eliminates the background and, in serial dilutions of a positive sample, shows a 500- to 1000-fold increase in sensitivity by liquid hybridization detection. We suggest that the background signal is arising from small fragments of DNA, which may be produced by autoclaving viral culture material. Such fragments would escape filtration, and overlapping fragments of DNA can prime one another to form complete mosaic sequences that will then amplify. Nested PCR, appropriately controlled for the number of cycles at each step, should successfully overcome such false positives caused by fragmented DNA, no matter if the contamination occurs at the collection site, in processing, or at the facility performing the test.

Flow Cytometry Sorting of Recombinant Mycobacterial Species Yields Bacterial Clones with Enhanced Insert Expression (2010)

Recombinant mycobacteria hold promise as vectors for delivery of HIV-1 and other pathogen antigen inserts for inducing systemic and mucosal immune responses. In general, the immunogenicity of the recombinant mycobacterial insert is proportional to the level of insert expression. In this study, a novel flow cytometry-based assay has been developed to sort live recombinant mycobacterial mutants with high expression of foreign inserts and to enrich those sorted bacterial populations. Sorted recombinant mycobacterial clones expressed higher levels of the ovalbumin SIINFEKL epitope, and select sorted clones showed better immunogenicity than unsorted recombinant mycobacteria. Thus, flow cytometry-based sorting can isolate recombinant mycobacteria enriched for higher insert expression.
Estimation of single-phase grid voltage parameters: An adaptive observer-based approach (2016)

This paper presents an adaptive observer-based approach for the estimation of single-phase grid voltage parameters under harmonic disturbances. The grid voltage is treated as a solution of a dynamic system and then an adaptive observer is developed based on the dynamic model. The proposed method is capable of estimating the grid voltage parameters including frequency, amplitude and phase angle asymptotically, with zero steady-state error. This conclusion is proved by means of passivity, Lyapunov-based arguments and La Salle's invariance principle. Simulation results are given to demonstrate the effectiveness of the proposed estimation strategy.
Residual Stress Measurement in Spot Welds and the Effect of Fatigue Loading Using High Sensitivity Moire Interferometry (1998)

Abstract Residual stress distribution has been determined in spot welds, which are generally used to join mild steel sheets. Various spot weld configurations were investigated using the full-field, experimental, optical technique of high sensitivity moiré interferometry. These stresses were found to be in the range 250–300 MPa (tensile) in the center and decreased to 40–100 MPa (tensile) at the edge of the weld nugget. Low cycle fatigue loading of the spot weld caused the residual stress to drop in the weld center by about 30% and increase at the edges by as much as 100%.
Macrophages Cause Reduced Biosynthesis of Hydrogen Sulfide in the Obese Microvasculature (2015)

Obesity is associated with recruitment of macrophages to the microvascular adventitia. The current objective was to define how macrophage‐derived signals contribute to microvascular dysfunction. Based on recent findings that impaired H 2 S signaling is associated with cardiovascular pathologies, it was hypothesized that in the diet‐induced mouse model of obesity microvascular H 2 S is depleted by a mechanism that involves interactions with perivascular macrophages. Mesenteric arterioles were isolated from 30 week‐old lean and obese mice and mounted for pressure myography. Vessels were loaded with the H 2 S indicator SF7‐AM and imaged using confocal microscopy. Obesity was associated with lower H 2 S levels in both the smooth muscle and endothelial layers. Generation of H 2 S is dependent on the substrate L‐cysteine and the enzyme cystathionine gamma‐lyase (CSE). Expression of CSE was not changed by obesity; however, L‐cysteine was less effective in evoking H 2 S production in these vessels, and was correlated with reduced relaxation when pre‐contracted with phenylephrine. Co‐culturing arterioles from lean mice overnight with peritoneal macrophages from obese mice resulted in vessel H 2 S depletion. In contrast, co‐culture of vessels from either lean or obese mice with macrophages from lean controls had no effects on vessel H 2 S. Taken together, these data support a model in which H 2 S biosynthesis is compromised in the obese microvasculature by a mechanism dependent on crosstalk with perivascular macrophages.

Development of an HDTV High-Speed Camera Using Three 2.2 M-Pixel CMOS Image Devices (2006)

An HDTV high-speed camera that uses three 2.2-M pixel Complementary Metal Oxide Semiconductor (CMOS) image devices has been developed. The camera enables image acquisition up to a maximum speed of 300 frames/sec and stores the image sequences directly in a semi-conductor memory in the camera head. Slow-motion playback is available with a high picture quality because the image sequence is stored without compression. The compact, lightweight, handheld camera can be controlled from a CCU (Camera Control Unit) with a single standard HDTV hybrid fiber-optic camera cable.
Genome sequence of Plasmopara viticola and insight into the pathogenic mechanism (2017)

Plasmopara viticola causes downy mildew disease of grapevine which is one of the most devastating diseases of viticulture worldwide. Here we report a 101.3 Mb whole genome sequence of P. viticola isolate 'JL-7-2' obtained by a combination of Illumina and PacBio sequencing technologies. The P. viticola genome contains 17,014 putative protein-coding genes and has ~26% repetitive sequences. A total of 1,301 putative secreted proteins, including 100 putative RXLR effectors and 90 CRN effectors were identified in this genome. In the secretome, 261 potential pathogenicity genes and 95 carbohydrate-active enzymes were predicted. Transcriptional analysis revealed that most of the RXLR effectors, pathogenicity genes and carbohydrate-active enzymes were significantly up-regulated during infection. Comparative genomic analysis revealed that P. viticola evolved independently from the Arabidopsis downy mildew pathogen Hyaloperonospora arabidopsidis. The availability of the P. viticola genome provides a valuable resource not only for comparative genomic analysis and evolutionary studies among oomycetes, but also enhance our knowledge on the mechanism of interactions between this biotrophic pathogen and its host.
Electrochemical Processing of Discrete Single-Walled Carbon Nanotube Anions (2013)

The dissolution of single-walled carbon nanotubes (SWCNTs) remains a fundamental challenge, reliant on aggressive chemistry or ultrasonication and lengthy ultracentrifugation. In contrast, simple nonaqueous electrochemical reduction leads to spontaneous dissolution of individualized SWCNTs from raw, unprocessed powders. The intrinsic electrochemical stability and conductivity of these nanomaterials allow their electrochemical dissolution from a pure SWCNT cathode to form solutions of individually separate and distinct (i.e., discrete) nanotube anions with varying charge density. The integrity of the SWCNT sp² framework during the charge/discharge process is demonstrated by optical spectroscopy data. Other than a reversible change in redox/solvation state, there is no obvious chemical functionalization of the structure, suggesting an analogy to conventional atomic electrochemical dissolution. The heterogeneity of as-synthesized SWCNT samples leads to the sequential dissolution of distinct fractions over time, with fine control over the electrochemical potential. Initial preferential dissolution of defective nanotubes and carbonaceous debris provides a simple, nondestructive means to purify raw materials without recourse to the usual, damaging, competitive oxidation reactions. Neutral SWCNTs can be recovered either by electroplating at an anode or by reaction with a suitable electrophile.
Robust Hand Geometry Measurements for Person Identification using Active Appearance Models (2007)

The increased demand for tighter border and building security has renewed public interest in biometric identification and verification systems. With fingerprint recognition being socially stigmatized, hand geometry-based recognizers have emerged as niche solutions. However, systems currently available in the marketplace require direct contact with the device, raising, among others, significant hygiene concerns. In this paper we introduce a novel approach to hand geometry-based identification. The proposed method employs Active Appearance Models to track the hand inside the capture device and to extract geometry features for identification. The AAM fitting algorithm runs faster than real-time, enabling robust system performance. In experiments on a small-scale database of hand images, the accuracy of our system exceeds 90% using as little as five features.
The Association of Multiple Interacting Genes with Specific Phenotypes in Rice Using Gene Coexpression Networks (2010)

Discovering gene sets underlying the expression of a given phenotype is of great importance, as many phenotypes are the result of complex gene-gene interactions. Gene coexpression networks, built using a set of microarray samples as input, can help elucidate tightly coexpressed gene sets (modules) that are mixed with genes of known and unknown function. Functional enrichment analysis of modules further subdivides the coexpressed gene set into cofunctional gene clusters that may coexist in the module with other functionally related gene clusters. In this study, 45 coexpressed gene modules and 76 cofunctional gene clusters were discovered for rice (Oryza sativa) using a global, knowledge-independent paradigm and the combination of two network construction methodologies. Some clusters were enriched for previously characterized mutant phenotypes, providing evidence for specific gene sets (and their annotated molecular functions) that underlie specific phenotypes.

Roles of PDGF in animal development (2003)

Recent advances in genetic manipulation have greatly expanded our understanding of cellular responses to platelet-derived growth factors (PDGFs) during animal development. In addition to driving mesenchymal proliferation, PDGFs have been shown to direct the migration, differentiation and function of a variety of specialized mesenchymal and migratory cell types, both during development and in the adult animal. Furthermore, the availability of genomic sequence data has facilitated the identification of novel PDGF and PDGF receptor (PDGFR) family members in C. elegans, Drosophila, Xenopus, zebrafish and mouse. Early data from these different systems suggest that some functions of PDGFs have been evolutionarily conserved.
Study of Phase Equilibrium of NaBr + KBr + H2O and NaBr + MgBr2 + H2O at 313.15 K (2017)

The phase equilibrium for the ternary systems NaBr + KBr + H 2 O and NaBr + MgBr 2 + H 2 O at 313.15 K was investigated by isothermal solution saturation method. The solubilities of salts and the densities of saturated solutions in these ternary systems were determined by chemical methods, while the equilibrium solid phases were analyzed by Schreinermarker wet residues method. Based on the experimental data, phase diagrams and density versus composition diagrams were plotted. The two ternary systems were type of simple common-saturation and without complex salt and solid solution. There are in all two crystalline regions, two univariant curves, and one invariant point in these phase diagrams of two ternary systems at 313.15 K. The equilibrium solid phases in the ternary system NaBr + KBr + H 2 O are KBr and NaBr·2H 2 O, and those in the ternary system NaBr + MgBr 2 + H 2 O are NaBr·2H 2 O and MgBr 2 ·6H 2 O.

Antibacterial activity of phytochemicals isolated from Erythrina zeyheri against vancomycin‐resistant enterococci and their combinations with vancomycin (2004)

Six phytochemicals were isolated from the roots of Erythrina zeyheri (Leguminosae) by repeated silica gel column chromatography using various eluting solvents. Extensive spectroscopic studies revealed that all were isoflavonoids. The antibacterial activity of the six compounds against vancomycin-resistant enterococci (VRE) was estimated by determining the minimum inhibitory concentration (MIC). Of the six isoflavonoids, erybraedin A ((6aR, 11aR)-3,9-dihydroxy-4,10-di(gamma,gamma-dimethylallyl)pterocarpan) exhibited the highest growth inhibitory potency against VRE with an MIC value of 1.56-3.13 microg/mL, followed by eryzerin C ((3R)-7,2',4'-trihydroxy-6,8-di(gamma,gamma-dimethylallyl)isoflavan) (MIC 6.25 microg/mL). These compounds also inhibited the growth of methicillin-resistant Staphylococcus aureus (MRSA) at 3.13-6.25 microg/mL. The antibacterial effects of the two compounds against VRE and MRSA were based on bacteriostatic action. When erybraedin A or eryzerin C was combined with vancomycin, the fractional inhibitory concentration (FIC) index against VRE ranged from 0.5306 to 1.0 and from 0.5153 to 0.75, respectively. The combinations also showed FIC indices of 0.6125-1.0 against MRSA. The results indicate that, depending on the case, both compounds act either synergistically or additively with vancomycin against VRE and MRSA. Erybraedin A and eryzerin C show evidence of being potent phytotherapeutic agents against infections caused by VRE and MRSA.
