Human Papillomavirus (HPV) 6, 11, 16, and 18 Seroprevalence Is Associated with Sexual Practice and Age: Results from the Multinational HPV Infection in Men Study (HIM Study) (2011)

Our study provides strong evidence that the practice of same-sex anal intercourse is an independent risk factor for seroprevalence of individual vaccine HPV types. Examination of antibody responses to HPV infections at various anatomic sites in future studies is needed to elaborate on the mechanism.
Nutriose, a prebiotic low-digestible carbohydrate, stimulates gut mucosal immunity and prevents TNBS-induced colitis in piglets (2009)

At the dose tested, LDC is a well-tolerated prebiotic agent able to not only stimulate butyrogenic bacteria strains and reduce intestinal transit disorders and energy intake, but also to prevent chronic inflammatory intestinal injuries.
Positive parenting style and positive health beyond the authoritative: Self, universalism values, and protection against emotional vulnerability from Spanish adolescents and adult children (2022)

The study findings question the universal benefits of the so-called positive parenting (the authoritative style) for positive health.
Suberoylanilide hydroxamic acid represses glioma stem-like cells (2016)

SAHA induces apoptosis and functions as a potent modulator of senescence via the p38-p53 pathway in GSCs. Our results provide a perspective on targeting GSCs via SAHA treatment, and suggest that SAHA could be used as a potent agent to overcome drug resistance in GBM patients.
Magneto-optical indicator film (MOIF) microscopy of granular and layer structures (abstract) (1996)

We report on the possibilities of application of magneto-optical indicator film (MOIF) technique for visualization and direct experimental study in real time of the magnetization processes and nondestructive characterization of the quality of magnetic thin granular films and multilayers. The technique utilizes a transparent indicator film, a Bi-substituted iron garnet with in-plane anisotropy, placed on the top of a sample. Polarized light passes through the indicator film and is reflected back by an Al underlayer. Magnetic stray fields with a component perpendicular to the film plane are observed through the magneto-optic Faraday effect created in the garnet film. An investigation of the magnetic moment distribution in granular single films and multilayers was carried out using this method. Some examples of magnetic stray field images of domain walls of different types obtained by MOIF technique and magnetic force microscopy are described. The experimental data are compared with theoretical estimations. The detailed information is obtained on the spin rotation processes as well as on the domain wall nucleation and motion during the remagnetization of these materials. Peculiarities of the magnetization reversal of multilayers with different types of exchange interlayer coupling have been revealed and discussed.
Serum Biomarkers of Dietary Fatty Acids are Associated with Abdominal Obesity Measures in a Large Population‐based Cohort of Men and Women. (2015)

Recent feeding trials suggest that the major saturated fatty acid (FA) Palmitic acid (PA, 16:0) and the major polyunsaturated FA linoleic acid (LA, 18:2n‐6) has diverse effects on abdominal fat accumulation, suggesting a beneficial role of LA on fat deposition. Objective To investigate associations between these FAs assessed in serum cholesterol esters (CE) and anthropometric measures of abdominal obesity. Methods LA and PA were measured by gas chromatography in serum CE. Sagittal abdominal diameter (SAD), waist circumference (WC), and waist‐hip ratio (WHR) were assessed by anthropometry in a population‐based cross‐sectional study of 3965 (1920 men and 2045 women) 60‐year old participants living in Stockholm county, Sweden. Results PA was positively correlated with SAD, WC, and WHR in men ( r = 0.15, 0.16, and 0.14, respectively; all p ˂0.001), whereas inverse correlations were observed for LA in both men ( r = ‐0.23, ‐0.22, and ‐0.22, respectively; p ˂0.001) and women ( r = ‐0.15, ‐0.18, and ‐0.18, respectively; p ˂0.001).Overall, these associations remained after adjusting for lifestyle factors. Conclusions Linoleic Acid was consistently inversely associated with all abdominal obesity measures in both men and women. Palmitic Acid showed positive correlations in men only. These findings support recent interventional data suggesting that a higher relative intake of dietary LA from vegetable oils is associated with decreased abdominal adiposity.
Foams of polyurethane/MWNT nanocomposites for efficient EMI reduction (2009)

High electrical conductivity is directly related to good EMI shielding effectiveness, while low permittivity is required in order to avoid wave reflection and promote wave absorption.Therefore, accurate foaming conditions must be found to reach both high conductivity and low permittivity. Nanocomposite preparation1 and 2 wt% MWNT (NC7000, Nanocyl, Belgium)/PU(Desmopan 2590A, Bayer, Germany) composites were prepared by melt blending in a twin-screw internal mixer (180C, 60 rpm, 5 min) and then molded into 2mm thick sheets under a hot press (180c) for 5min.
Reduction in glomerular pore size is not restricted to pregnant women. Evidence for a new syndrome: ‘Shrunken pore syndrome’ (2015)

The plasma levels of cystatin C, β2-microglobulin, beta-trace protein, retinol binding protein (RBP) and creatinine were determined in plasma samples from 111 randomly selected patients with eGFRcystatin C ≤ 60% of eGFRcreatinine and from 55 control patients with 0.9eGFRcreatinine ≤ eGFRcystatin C ≤ 1.1eGFRcreatinine (eGFRcystatin C ≈ eGFRcreatinine). The concentration ratios of cystatin C/creatinine, β2-microglobulin/creatinine, beta-trace protein/creatinine and RBP/creatinine were significantly higher in patients with eGFRcystatin C ≤ 60% of eGFRcreatinine than in patients with eGFRcystatin C ≈ eGFRcreatinine. When the patients were divided into three groups with different estimated GFR intervals (≤ 40, 40-60 and ≥ 60 mL/min/1.73m(2)) the concentration ratios of cystatin C/creatinine, β2-microglobulin/creatinine, and beta-trace protein/creatinine were significantly higher in patients with eGFRcystatin C ≤ 60% of eGFRcreatinine than in patients with eGFRcystatin C ≈ eGFRcreatinine for all GFR intervals. Similar results were obtained when the population without pregnant women was studied as well as the subpopulations of men or of non-pregnant women. Populations of pre-eclamptic women and pregnant women in the third trimester display similar results. Since the production of these four proteins with sizes similar to that of cystatin C is not co-regulated, the most likely explanation for the simultaneous increase of their creatinine-ratios in patients with eGFRcystatin C ≤ 60% of eGFRcreatinine is that their elimination by glomerular filtration is decreased. We suggest that this is due to a reduction in pore diameter of the glomerular membrane and propose the designation 'Shrunken pore syndrome' for this pathophysiological state.
The influence of chemical composition, aerosol acidity, and metal dissolution on the oxidative potential of fine particulate matter and redox potential of the lung lining fluid (2021)

Air pollution is a major environmental health risk and it contributes to respiratory and cardiovascular diseases and excess mortality worldwide. The adverse health effects have been associated with the inhalation of fine particulate matter (PM<sub>2.5</sub>) and induction of respiratory oxidative stress. In this work, we quantified the oxidative potential (OP) of PM<sub>2.5</sub> from several Canadian cities (Toronto, Hamilton, Montreal, Vancouver) using a recently developed bioanalytical method which measures the oxidation of lung antioxidants, glutathione, cysteine, and ascorbic acid, the formation of glutathione disulfide and cystine, and the related redox potential (RP) in a simulated epithelial lining fluid (SELF). We evaluated the application of empirical SELF RP as a new metric for aerosol OP. We further investigated how PM<sub>2.5</sub> chemical composition and OP are related across various emission source sectors and whether these features are linked to specific properties of aerosol aqueous phase, such as pH and metal-ligand complexation. The OP indicators including SELF RP were strongly correlated among each other, indicating that the empirical RP could be used as a reliable metric in future studies. OP based on ascorbic acid showed dependency on the emission source sectors, most likely due to variation in the solubility of Fe. Traffic emissions resulted in the highest OP, followed by industrial emissions and resuspended crustal matter. OP presented low correlation with PM<sub>2.5</sub> concentrations, low-moderate correlation with the aerosol organic matter, and moderate-strong association with black carbon and transition metals across the sites. We did not find strong association between the concentration of biomass burning tracers and OP. Copper was the only metal that showed high association with OP across all sites, whereas the correlation with other metals, such as iron, manganese, and titanium, showed clear dependency on the source sectors. The aerosol pH correlated negatively with ambient temperature and positively with biomass burning tracers and the levels of nitrate, ammonium, and aerosol liquid water content. The solubility of Fe was associated with sulfate and aerosol pH at most sites, suggesting the involvement of proton-mediated dissolution pathway, while this was not visible at the site influenced by industrial emission, most likely due to the abundance of pyrogenic Fe. The effect of metal-ligand complexation on the solubility of transition metals, in particular Fe, was clearly observed at all sites, whereas a combined effect with aerosol pH, and a subsequent impact on OP, was only seen at the traffic site in Toronto. The enhanced solubility of Fe due to proton- and ligand-mediated dissolution pathways and subsequent formation of reactive oxygen species may in part explain the health effects of PM<sub>2.5</sub> seen in previous epidemiological studies.
Characterization of Nb-Microsegregation and Eutectic Carbide in As-Cast Nb-Microalloyed Al-Free Case Hardening Steel (2017)

The current work involves systematic experimental examination of the as-cast microstructure of a Nb-microalloyed Al-free case hardening steel, 18CrNiMo7-6, with 0.078 wt pct Nb. The aim is a thorough quantification and characterization of Nb-microsegregation and eutectic NbC. A combination of optical microscopy (OM), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and electron probe microanalysis with energy dispersive and wavelength dispersive X-ray spectroscopy (EPMA, EDS, and WDS) are used for this purpose. Eutectic NbC is characterized for its location, shape, size, and amount. Differential scanning calorimetry (DSC) measurements indicate that γ-Fe − NbC eutectic forms in the temperature range of 1399–1390 °C, while Scheil simulation predicts this range to be ≈1418–1402 °C. The average eutectic composition is measured to be 10.91 wt pct Nb using EDS. γ-Fe − NbC eutectic in steel can be classified as an irregular eutectic with faceted (NbC) and non-faceted (γ-Fe) constituent phases. Scheil solidification simulation predicts that about 30 mole pct of the total NbC in this steel can be present in the form of eutectic. These results, thus, point out the need for modification of the eutectic via alteration of cooling rate or using modifiers.
Molecular volumes and the Stokes-Einstein equation (1970)

By adopting a simple notion of the volume of a molecule it has been possible to produce an empirical correction factor for the Stokes equation to enable one to apply it to molecules down to two angstroms in radius.
Influence of purinoceptors' agonists and antagonists on opossum internal anal sphincter (1988)

Studies were performed in alpha-chloralose-anesthetized and pancuronium-treated opossums. Resting internal anal sphincter pressures (IASP) were monitored using low-compliant continuously perfused catheters. P1 and P2 purinoceptor agonists, adenosine and ATP, respectively, administered close intra-arterially, caused dose-dependent decreases in the IASP. The inhibitory effect of these agonists on the IASP was tetrodotoxin resistant. Rectal balloon distension (RD) (which mimics the rectoanal inhibitory reflex) caused volume-dependent IAS relaxation. Electrical stimulation of the sacral nerve (SNS) also produced frequency-dependent decreases in IASP. The inhibitory response to adenosine (P1 purinoceptor agonist), ATP (P2 purinoceptor agonist), RD, and SNS on the internal anal sphincter (IAS) was examined before and after 8-phenyltheophylline (P1 purinoceptor antagonist) and alpha,beta-methylene ATP (P2 purinoceptor antagonist that irreversibly binds and desensitizes P2 purinoceptor). P1 and P2 purinoceptor antagonists produced selective antagonism of the inhibitory responses on the IAS of their respective agonists only. Furthermore, high doses of adenosine and ATP produced desensitization and block of their own actions only. The purinoceptors' antagonists, and the desensitization of purinoceptors by high doses of adenosine and ATP, failed to modify the fall in IASP in response to RD or SNS. From these studies we conclude that distinct inhibitory P1 and P2 purinoceptors are present on the IAS smooth muscle. However, these inhibitory purinoceptors may not be responsible for the rectoanal reflex-mediated IAS relaxation.
High-frequency ultrasound detection of the temporal evolution of protein cross linking in myocardial tissue (2000)

The progressive increase in stiffening of the myocardium associated with the aging process and abetted by comorbid conditions such as diabetes may be linked to an excessive number of collagen cross links within the myocardial extra-cellular matrix. To determine whether ultrasound can delineate changes in the physical properties of heart tissue undergoing cross linking, the authors employed a model in which increased cross linking was induced by treating rat myocardial tissue with specific chemical fixatives. Rat hearts (n=5 each group) were arrested at end-diastole, insonified (30 to 50 MHz) fresh within a few minutes of excision in a phosphate buffered solution, placed in a fixative (10% formalin or 2.5% glutaraldehyde) and insonified at 30-minute intervals thereafter for 24 hours. Ultrasonic attenuation increased in tissues cross linked with formalin (maximal change: 27.2+/-3.4 dB/cm) and glutaraldehyde (maximal change: 40.2+/-5.6 dB/cm) over a 24-hour period. The frequency dependence of the attenuation coefficient increased as a function of the extent of collagen cross links in formalin (maximal change: 0.8+/-0.3 dB/cm-MHz) and glutaraldehyde (maximal change: 0.9+/-0.6 dB/cm-MHz). This study represents the first time that the precise time course of myocardial protein cross linking in situ has been characterized by using real time monitoring, and the physiologic effect has been delineated on microscopic material properties.
Replamineform: A New Process for Preparing Porous Ceramic, Metal, and Polymer Prosthetic Materials (1972)

The replamineform process (meaning replicated life forms) is a technique for duplicating the microstructure of carbonate skeletal components in ceramic, metal, or polymer materials. The special pore structures of marine invertebrate skeletal materials such as echinoid spines and corals, which are difficult or impossible to create artificially, can thus be copied in useful materials. Of immediate interest is the possibility of using these replicated microstructures in the fabrication of orthopedic prosthetic devices. By means of this technique, prosthetic materials having a controlled pore microstructure for optimum strength and tissue ingrowth may be obtained.
Products of Cytochrome P450BioI (CYP107H1)-Catalyzed Oxidation of Fatty Acids (2003)

[reaction: see text] Oxidation of tetradecanoic and hexadecanoic acids by cytochrome P450(BioI) (CYP107H1) produces mainly the 11-, 12-, and 13-hydroxy C(14) fatty acids and the 11- to 15-hydroxy C(16) fatty acids, respectively. In contrast to previous reports, terminal hydroxylation is not observed. The enantiospecificity of fatty acid hydroxylation by P450(BioI) was also determined, and the enzyme was shown to be moderately selective for production of the (R)-alcohols.
A finite double-layer slot array structure for spatial power combining amplifiers (2002)

Arrays of active antennas are finding applications in spatial power combining systems and in phased array radar. In a spatial power combiner the power produced by a large number of solid-state amplifier cells is combined in free space to produce potentially large amounts of millimeter-wave power. Phased array radar systems with each element having an active module also combine power spatially, but more importantly enable tight control of radiated beam characteristics. We have previously analyzed a grid amplifier spatial power combiner where amplifier cells are located at the intersections of a conductor grid. The grid forms the input and output coupling antennas. In this paper we address the modeling of as array of stripline coupled slot antennas. The unit cell has an amplifier, typically a MIMIC in the center of the stripline. In addition to the problem size, one characteristic of this system is the tight coupling of the nonlinear device to its electromagnetic environment. This system has high isolation between the input and the output field. One of the challenges is to select and design this type of array to satisfy good transmission between the input and the output. The aim of the work presented is the development of models of the slot array for use in a nonlinear circuit simulator.

Tomlinson-Harashima Precoding for Multiuser MIMO Systems (2009)

Traditional Tomlinson-Harashima Precoding (THP), which leaves all the equalization tasks to the transmitter, prevent from fully utilizing the advantages of MIMO techniques. In this paper, a THP scheme for multiuser MIMO system is proposed. The inter-user interference is preequalized at transmitter, while the intra-user interference is equalized at each receiver. Through block lower triangular decomposition of channel matrix and waterfilling under throughput maximization criterion, the proposed scheme achieves much better sum rate performance when compared to traditional THP designed for single antenna system.
Time-Dependent Stochastic Equilibrium Assignment Model Considering Activity Choices (2007)

This paper demonstrates an applicability of the traffic assignment model overcoming drawbacks of conventional models. The main characteristics of the proposed model are as follows: (1) The model integrates trip generation (i.e. activity choice), destination choice, mode choice and route choice; (2) Traveler’s choice behavior is assumed to be expressed as a nested logit structure; and (3) This model considers hourly variation of traffic condition. The applicability of the model is shown under application to Nagoya Metropolitan Area, Japan. These results suggest that the model allows us to compare various TDM policies effectively and evaluate in detail.
Neutron Decay Array for beta-delayed neutron Decay Studies (2010)

The Neutron Emission Ratio Observer (NERO), has been constructed for use at the National Superconducting Cyclotron Laboratory to work in conjunction with the NSCL Beta Counting System BCS [1] in order to detect -delayed neutrons. The design of the detector provides high and flat efficiency for a wide range of neutron energies, as well as a low neutron background.
Computer-Aided Power Requirements (2003)

The power requirement of machinery is a necessary consideration for the sizing and selection of machine elements in the design process. The decision process of designing gears, belt drives, clutches, brakes, and bearings are designed and sized based on the power requirement of the application. I have written a software program that calculates the power requirements for three different design applications. This software program simplifies and streamlines the design and selection process by allowing the student to calculate the horsepower and torque requirement.
Multi-image gradient-based algorithms for motion estimation (2001)

Image registration algorithms based on gradient methods provide quantitative motion measurements from sequences of video im- ages. Although such measurements can be degraded by image noise, larger degradations typically result from systematic bias in the algorithms that is present even if the images are noise-free. To improve the accu- racy of motion measurements, we develop a new class of multi-image algorithms based on multidimensional digital filters. The new algorithms provide better estimates of spatial and temporal gradients and also com- pensate for motion blur caused by the nonzero acquisition time of the imager. We optimize filters to measure arbitrary motions, and we illus- trate the results when those filters are used to estimate constant velocity movements. We also show results for filters that are optimized for har- monic analysis of periodic motions. Using these algorithms, systematic bias in the amplitude of sinusoidal motion is less than 0.001 pixels for motions smaller than 1 pixel in amplitude. This represents a hundredfold decrease in bias compared to existing methods. © 2001 Society of Photo-
Uma distinção entre problemas aritméticos e algébricos (2008)

"Apesar do volume considerável de pesquisas sobre resolução problemas, falta, na literatura, uma resposta que apresente uma maneira consistente de distinguir os problemas aritméticos dos problemas algébricos. Nesse sentido, objetivamos apresentar uma proposta de distinção entre os problemas aritméticos e os problemas algébricos, com base nas propriedades de igualdade. Além disso, buscamos analisar algumas conseqüências imediatas dessa proposta. Os resultados obtidos indicam que muitos problemas envolvendo operações com números naturais, fracionários e porcentagem que, normalmente, são aceitos como problemas aritméticos, na realidade, são algébricos. Essa interpretação errônea, quando levada para a Matemática escolar, muitas vezes, causa aos discentes dificuldades para resolver problemas."
Novel solid-phase assay of ketone bodies in urine (1991)

This simple dip-and-read color-matching assay measures ketone bodies in urine. The result is matched with any of the seven colors provided in a color chart. The intensity and hue of the color formed depends on the concentration of acetoacetic acid and follows a gradation starting from light purple (0.2 mol/L acetoacetate) to dark purple and finally to dark violet (9 mol/L). The color developed is independent of pH in the range pH 4-9.5, and is stable for at least 1 h. 3-Hydroxybutyric acid produced no color at the concentrations tested (less than or equal to 100 mmol/L), and acetone was detectable only when greater than or equal to 15 mmol/L. The test was compared with the Ames Ketostix assay in subjects who were on restricted-calorie weight-loss programs. The two methods showed good agreement, except that 20% (21/103) of samples that were negative by Ketostix were read as positive by the new method, which may be more sensitive (detection limit = 0.2 mmol/L). Measurement of urine ketones was unreliable (in comparison with measurement of blood or breath acetone) for monitoring the rate of fat loss during a negative calorie balance.
