Conducting ferrofluid: a high-performance microwave shielding material (2014)

Conducting materials based on reduced graphene oxide (RGO) sheets have become the focus of considerable research interest in recent years because of the scientific and technological significance of these materials. Herein, we report the fabrication of conducting ferrofluid composites of reduced graphene oxide and nanoscale Fe3O4 (5–20 nm) particles made using a simple yet versatile co-precipitation method. Raman spectroscopy was performed to elucidate the graphitic structure of RGO and interaction between ferrofluid nanoparticles and RGO, which shows a slight shift in the peak position of RGO (shifting from 1360 to 1348 cm−1 in the D band and 1604 to 1593 cm−1 in the G band) and ferrofluid. This shift in the bands is an evidence of a strong interaction between these two components. The magnetic and electromagnetic shielding properties of these conducting ferrofluid composites having different loadings of reduced graphene oxide sheets were investigated. In addition, the high value of microwave shielding, 41 dB (99.9% attenuation) results from the combined effect of magnetic losses (natural resonance and eddy currents) due to ferrofluid and dielectric losses (natural resonance, dipole relaxation, electron polarization related relaxation, interfacial polarization, residual defects in RGO sheets and higher conductivity) due to reduced graphene oxide. The as-synthesized conducting ferrofluid could be a promising candidate for the next generation building block material in microwave shielding applications with vast utilities in the radio frequency range.
Contribution of NF-kappa B and Sp1 binding motifs to the replicative capacity of human immunodeficiency virus type 1: distinct patterns of viral growth are determined by T-cell types (1991)

Starting with a replication-incompetent molecular clone of human immunodeficiency virus type 1, lacking all the NF-kappa B and Sp1 binding sites present in the native long terminal repeat (LTR), proviruses containing reconstructed LTRs with individual or combinations of NF-kappa B and Sp1 elements were generated and evaluated for their capacity to produce virus progeny following transfection-cocultivation. Virus stocks obtained from these experiments exhibited a continuum of replicative capacities in different human T-cell types depending on which element(s) was present in the LTR. For example, in experiments involving proviral clones with LTRs containing one or two NF-kappa B elements (and no Sp1 binding sites), a hierarchy of cellular permissivity to virus replication (peripheral blood lymphocytes = MT4 greater than H9 greater than CEM greater than Jurkat) was observed. Of note was the associated emergence of second-site LTR revertants which involved an alteration of the TATA box. These results suggest that the human immunodeficiency virus type 1 LTR possesses functional redundancy which ensures virus replication in different T-cell types and is capable of changing depending on the particular combination of transcriptional factors present.
Applications of Ventilation Lung Imaging with81mKrypton (1977)

A method for the evaluation of regional lung ventilation using 81mKr eluted from a rubidium generator is described. The tracer distribution at equilibrium is a function of regional ventilation, not of volumes. The study can be performed on a wide range of patients, including unconscious and mechanically ventilated patients, and can be performed immediately following or concurrently with a perfusion study. Thus, precisely comparable ventilation and perfusion images can be obtained.
Studies on nitroaniline–sulfuric acid compositions: Aphrogenic pyrostats (1970)

Abstract Nitroaniline‐sulfuric acid compositions, a source of a new class of aphrogenic pyrostats (intumescent fire‐quenching agents) have been studied. Thermogravimetric analysis of the compositions and their expansion products was carried out. The chemical compositions of the foams were determined, and considerable similarity was noted. Sulfur is present exclusively as sulfonic acid groups. Appreciable deamination occurs during expansion, particularly at higher acidic content. Sulfur dioxide and water are major gaseous constituents. Only 2‐ and 4‐nitroanilines can be converted into voluminous foams; they behave like difunctional monomers. 3‐Nitroaniline expands only slightly into brittle products; it acts like a trifunctional monomer.
Role of hPHF1 in H3K27 Methylation and Hox Gene Silencing (2007)

Polycomb group (PcG) proteins are required for maintaining the silent state of the homeotic genes and other important developmental regulators. The silencing function of the PcG proteins has been linked to their intrinsic histone modifying enzymatic activities. The EED-EZH2 complex, containing the core subunits EZH2, EED, SUZ12, and RbAp48, functions as a histone H3K27-specific methyltransferase. Here we describe the identification and characterization of a related EED-EZH2 protein complex which is distinguished from the previous complex by the presence of another PcG protein, hPHF1. Consistent with the ability of hPHF1 to stimulate the enzymatic activity of the core EED-EZH2 complex in vitro, manipulation of mPcl1, the mouse counterpart of hPHF1, in NIH 3T3 cells and cells of the mouse male germ cell line GC1spg results in global alteration of H3K27me2 and H3K27me3 levels and Hox gene expression. Small interfering RNA-mediated knockdown of mPcl1 affects association of the Eed-Ezh2 complex with certain Hox genes, such as HoxA10, as well as Hox gene expression concomitant with an alteration on the H3K27me2 levels of the corresponding promoters. Therefore, our results reveal hPHF1 as a component of a novel EED-EZH2 complex and demonstrate its important role in H3K27 methylation and Hox gene silencing.

Measurement ofϕProduction in Proton-Nucleus Collisions at 400 GeV/c (1977)

We have measured the invariant cross section for inclusive $\ensuremath{\phi}$ production in proton-nucleus collisions at 400 GeV/c near Feynman $x=0$. For transverse momenta in the range between 0.8 and 3.5 GeV/c the ratio of $\ensuremath{\phi}$ to ${\ensuremath{\pi}}^{\ensuremath{-}}$ rises from 1 to 7%. We also report on correlations with particles opposite the $\ensuremath{\phi}$ in the center-of-mass system as they relate to the Okubo-Zweig-Iizuka rule.
Asian Pacific Islander Americans and Affirmative Negative Action (2012)

With a focus on the Asian and Pacific Islander American (APIA) community, I begin by defining affirmative action and tracing its history and metamorphosis over the past 50 years. What once was a policy to support marginalized groups like the APIA community is now evolving into negative action – a tool to prevent mobility and access to higher education. Negative action, which stretches back to the 1980s, is a way for institutions of higher education to prevent the admission of candidates of Asian or Pacific Islander descent because of their rising numbers in enrollment and their accompanying perceived success. This paper spotlights the University of California, Los Angeles and Berkeley campuses, and how the Board of Regents has modified both eligibility and admission policies that may seem to promote equality and equity for all candidates, but actually support the practice of negative action. Grounded in the model minority myth, negative action maintains the status quo of White dominance. This paper will address the existence and consequences of negative action, its connection with the model minority myth, and its potential future impacts.
Colloid deposition experiments as a diagnostic tool for biomass attachment onto bioproduct adsorbent surfaces (2008)

Abstract BACKGROUND: Detrimental processing conditions can be expected in any downstream operation where direct contacting between a crude feedstock and a reactive solid phase is supposed to occur. In this paper we have investigated the factors influencing intact yeast cells deposition onto anion and cation exchangers currently utilized for expanded‐bed adsorption of biotechnological products. The aim of this study was twofold: (a) to confirm previous findings relating biomass deposition with surface energetics according to the extended Derjaguin, Landau, Verwey and Overbeek theory (XDLVO) theory; and (b) to provide a simple experimental tool to evaluate biomass deposition onto process surfaces. RESULTS: Biomass deposition experiments were performed on an automated workstation utilizing a packed‐bed format. Two commercial ion exchangers intended for the direct capture of bioproducts in the presence of suspended biological particles were employed. Intact yeast cells in the late exponential phase of growth were selected as model bio‐colloids. Cell deposition was systematically evaluated as a function of fluid‐phase conductivity and quantitatively expressed as a biomass deposition parameter (α). CONCLUSION: α ≤0.15 was established as a criterion to reflect negligible biomass adhesion to the process support(s). Biomass deposition experiments further confirmed predictions made on the basis of free interfacial energy calculations as per the extended DLVO approach. Copyright © 2008 Society of Chemical Industry
Transceiver optimization for multi-user multi-antenna two-way relay channels (2011)

In this paper, we study a multi-user multi-antenna two-way relay system, where a multi-antenna base station (BS) exchanges uplink and downlink signals with multiple users via a multi-antenna amplify-and-forward relay station (RS). We jointly design the BS and RS transceivers, aiming to maximize the system bidirectional sum rate under inter-user interference free constraint. Since the optimization problem is non-convex, we employ alternating optimization algorithm to design the transmit and receive weighting matrices at the BS and RS. Simulation results show that the proposed solution offers higher bidirectional sum rate than existing schemes.

The findings suggest a valuable therapeutic role of LAB especially when incorporated into alginate beads for the treatment of CFS.
Diabetes is Associated with Higher Trimethylamine N-oxide Plasma Levels (2016)

Recent studies have revealed strong associations between systemic trimethylamine N-oxide (TMAO) levels, atherosclerosis and cardiovascular risk. In addition, plasma L-carnitine levels in patients with high TMAO concentrations predicted an increased risk for cardiovascular disease and incident major adverse cardiac events. The aim of the present study was to investigate the relation between TMAO and L-carnitine plasma levels and diabetes. Blood plasma samples were collected from 12 and 20 weeks old db/db mice and patients undergoing percutaneous coronary intervention. Diabetic compared to non-diabetic db/L mice presented 10-fold higher TMAO, but lower L-carnitine plasma concentrations at 12 weeks of age. After 8 weeks of observation, diabetic db/db mice had significantly increased body weight, insulin resistance and TMAO concentration in comparison to non-diabetic control. In 191 patients undergoing percutaneous coronary intervention the median (interquartile range) plasma concentration of TMAO was 1.8 (1.2-2.6) µmol/L. Analysis of the samples showed a bivariate association of TMAO level with age, total cholesterol and L-carnitine. The multivariate linear regression analysis revealed that, in addition to L-carnitine as the strongest predictor of log transformed TMAO (p<0.001), the parameters of age, diabetes status and body mass index (BMI) were independently associated with increased log transformed TMAO levels (p<0.01).Our data provide evidence that age, diabetes and BMI are associated with higher TMAO levels independently of L-carnitine. These data support the hypothesis of TMAO as a cardiovascular risk marker and warrant further investigation of TMAO for diabetes research applications.
Automated extraction of local defect resonance for efficient non-destructive testing of composites (2018)

Local defect resonance (LDR) makes use of high frequency vibrations to get a localized resonant activation of the defect. One of the major difficulties with respect to the use of LDR for non-destructive testing is the actual identification of the LDR frequency. In this study, different post-processing methods are applied to broadband vibration data, obtained for a carbon fiber reinforced plastic with a flat bottom hole, in view of automated extraction of LDR features. Results are shown and discussed in the frequency domain. In order to reduce the computational effort for large datasets, principle component analysis (PCA) and frequency band data (FBD) calculation are investigated. The effect on the calculation time and the data size is investigated. Moreover, a signal-to-noise ratio is introduced to investigate the performance of both techniques with respect to the automated LDR detection algorithm. Finally, the effect of a reduced sampling is investigated with respect to the performance of the automated LDR extraction procedure.
Esterification of Self-Assembled Carboxylic-Acid-Terminated Thiol Monolayers in Acid Environment: A Time-Dependent Study (2009)

This contribution reports on the influence of acids on the quality of carboxylic-acid-terminated self-assembled monolayers (SAMs) on gold prepared from ethanolic solution of HS-(CH(2))(15)-COOH and HS-(CH(2))(11)CONH-(EG)(6)CH(2)-COOH. Null ellipsometry, contact angle goniometry, and infrared reflection-absorption spectroscopy are used to monitor the physical and chemical changes occurring within the SAMs upon acid post treatment; after incubation with acids present in the solution; and after incubation in aged acid containing solutions. The presence of acid has a positive effect on the crystallinity, packing, and orientation of the supporting alkyl and ethylene glycol subunits of the SAM. Our studies also confirm previous findings stating that the carboxylic groups are rapidly converted into ethyl ester groups in the presence of hydrochloric acid in the incubation solution. It is also evident that the conversion occurs in the presence of the weaker acid, acetic acid, although at a much slower rate than that for hydrochloric acid. This is a new observation that has not been reported on before. The physical and chemical characterization is also complemented with a functional bioaffinity study. The functional evaluation revealed that the present model system was surprisingly insensitive to the degree of esterification of the carboxylic acid groups, but that 4 weeks of storage of the two investigated thiols in hydrochloric acid containing ethanol resulted in SAMs that were completely inactive with respect to immobilization and subsequent binding of the antigen. It was encouraging to note that the nonspecific binding of both antigen and antibody was extremely low on the two SAMs, regardless of the relative amount of ethyl esters on the surface.
Stapes piston insertion depth and clinical correlations (2019)

<b>Background:</b> The insertion of the stapes piston within the vestibule provides the physical basis for a successful stapedotomy. An insertion depth of 0.5 mm is recommended to avoid the dislocation of the stapes prosthesis (e.g. sneezing). <b>Aims:</b> The objective of this study is to analyze the depth of stapes prosthesis insertion and its correlation with clinical outcome. <b>Material and methods:</b> We observed in a retrospective case series 39 otosclerosis patients after a stapedotomy and a postoperative performed flat panel tomography/cone beam CT. The evaluation included the radiologically found depth of prosthesis insertion within the vestibule, the vestibule depth, and the correlation with the bone conduction (BC) threshold, vertigo, and tinnitus. <b>Results:</b> Insertion depth varied between 0.2 and 1.6 mm (mean 0.74 mm). The ratio of insertion depth versus the vestibule depth was between 8% and 59% (mean 26.6%). We observed no correlation between the insertion depth, the length of the prosthesis, the ratio of insertion depth/vestibule depth, postoperative BC, appearance of vertigo, or tinnitus. <b>Conclusions and significance:</b> In our group, we observed no significant relation between insertion depth of the stapes piston, postoperative vertigo, tinnitus, or decrease of the BC.
Inhibition of hyphal development and kill of Candida albicans blastospores by noxythiolin in vitro (1986)

The cidal activity of the antimicrobial agent, noxythiolin, was investigated against a laboratory strain and a fresh isolate of Candida albicans. The order of resistance to noxythiolin was hyphal form (isolate) greater than or equal to 25 degrees C-grown blastospores (isolate) greater than 37 degrees C-grown blastospores (isolate) greater than laboratory strain blastospores. Noxythiolin activity was superior to that of 'equivalent' formaldehyde concentrations. Mycelial transformation in C. albicans was examined by light and scanning electron microscopy and measured in terms of percentage germination and hyphal extension. Noxythiolin, 2.5%, in contact for 30 min prevented germination of the blastospore population whereas the decomposition products, formaldehyde and N-methylthiourea, showed no appreciable effect in the expected concentrations. The implications of these results are discussed in relation to the observed clinical efficacy of noxythiolin.
Molecular Cloning of the cDNA Encoding Human Deoxyribonuclease II (1998)

A rapid amplification of cDNA ends method, using degenerate oligonucleotides based upon the N-terminal amino acid sequence of human hepatic deoxyribonuclease II (DNase II), allowed a novel cDNA encoding DNase II to be constructed from thyroid gland RNA. The composite nucleotide sequence (1593 bases) included an open reading frame of 1080 bases, which encoded a single polypeptide of 360 amino acids (signal peptide, 16; propeptide, 91; mature protein, 253). Although the sequence of DNase II showed no significant homology to other mammalian proteins, its cDNA structural organization resembled those of the lysosomal cathepsin families. The two parts of the cDNA corresponding to the propeptide and the mature protein were expressed in Escherichia coli, and the recombinant polypeptides thus obtained were strongly stained with an anti-DNase II antibody on Western blotting. DNase II is ubiquitously expressed in human tissues, and the DNase II gene (DNASE2) was assigned to chromosome 19.
Quantitative Analysis of Cyclooxygenase Metabolites of Arachidonic Acid (2003)

Metabolism of arachidonic acid results in a host of biologically active compounds with profound effects on airway inflammation (1). After activation of cellular phospholipases and release of free arachidonic acid, catalyzed insertion of oxygen occurs enzymatically via action of one of the two known cyclooxygenase isoenzymes (COX-1 and COX-2). The unstable bicyclic intermediate, PGH(2), undergoes subsequent metabolism to form prostaglandins (PG), thromboxane (Tx), and leukotrienes (LT) (see Fig.1). In addition, free radicals can oxygenate arachidonate although it is bound to the diacylgycerol backbone of membrane phospholipids. The family of compounds formed in this way, known as isoprostanes, are stereochemically different and incorporate a large number of regioisomeric compounds that may confound measurement of PG (2-5 and see Chapter 33 ). Arachidonic acid can also be metabolized by specific cytochrome P(450) enzymes to regioisomeric epoxides and stereo specific hydro xyeicosatetraenoic (HETE) acids (6). Fig. 1. Overview of pathways of metabolism of arachidonic acid during airway inflammation. Following activation of cellular phospholipases, arachidonic acid is cleaved from membrane phospholipids. It is undergoing dioxygenation catalyzed by cyclooxygenase (either COX-1 or COX-2 isoforms) to form the unstable endoperoxide intermediate PGH2. Specific isomerases with varied cellular distribution further metabolize PGH2 to bioactive prostaglandins and thromboxanes.
