Endothelial modulation of coronary vasomotor tone in humans. Effects of atherosclerosis and risk factors for coronary artery disease. (1994)

Tests in patients with atherosclerosis or running the risk to get coronary heart diseases have been reported, the objective of which was to detect the importance the physiologic and pathophysiologic regulatory mechanisms of coronary blood flow have in early diagnosis. The reaction of coronary vessels after the infusion of acetylcholine compared to this they showed after the infusion of papaverine was tested, this is to say the responsiveness of coronary vessels to pharmacologic influences caused by the endothelium and aiming directly at the striatal muscles. Both, quantitative coronary angiography and intracoronary sonography served as measuring instruments. The results revealed that progressive endothelial dysfunction in the coronary vessels of risk patients can be detected by the help of pharmacologically differentiated active substances. In patients with increased cholesterin levels, the function of the endothelium is impaired, although a constriction of the lumen has not been observed. Some gradually more distinct dysfunctions have been found in patients with structural symptoms of coronary atherosclerosis and above all in patients with angiographically provable lumen alterations.
Recyclable, Flexible, Low‐Power Oxide Electronics (2012)

Abstract The ability to process and dimensionally scale field‐effect transistors with and on paper and to integrate them as a core component for low‐power‐consumption analog and digital circuits is demonstrated. Low‐temperature‐processed p‐ and n‐channel integrated oxide thin‐film transistors in the complementary metal oxide semiconductor (CMOS) inverter architecture are seamlessly layered on mechanically flexible, low‐cost, recyclable paper substrates. The possibility of building these circuits using low‐temperature processes opens the door to new applications ranging from smart labels and sensors on clothing and packaging to electronic displays printed on paper pages for use in newspapers, magazines, books, signs, and advertising billboards. Because the CMOS circuits reported constitute fundamental building blocks for analog and digital electronics, this development creates the potential to have flexible form factor computers seamlessly layered onto paper. The holistic approach of merging low‐power circuitry with a recyclable substrate is an important step towards greener electronics.
Crystal, magnetic, calorimetric and electronic structure investigation of GdScGe1–xSbxcompounds (2017)

Experimental investigations of crystal structure, magnetism and heat capacity of compounds in the pseudoternary GdScGe-GdScSb system combined with density functional theory projections have been employed to clarify the interplay between the crystal structure and magnetism in this series of RTX materials (R = rare-earth, [Formula: see text] = transition metal and X = p-block element). We demonstrate that the CeScSi-type structure adopted by GdScGe and CeFeSi-type structure adopted by GdScSb coexist over a limited range of compositions [Formula: see text]. Antimony for Ge substitutions in GdScGe result in an anisotropic expansion of the unit cell of the parent that is most pronounced along the c axis. We believe that such expansion acts as the driving force for the instability of the double layer CeScSi-type structure of the parent germanide. Extensive, yet limited Sb substitutions [Formula: see text] lead to a strong reduction of the Curie temperature compared to the GdScGe parent, but without affecting the saturation magnetization. With a further increase in Sb content, the first compositions showing the presence of the CeFeSi-type structure of the antimonide, [Formula: see text], coincide with the appearance of an antiferromagnetic phase. The application of a finite magnetic field reveals a jump in magnetization toward a fully saturated ferromagnetic state. This antiferro-ferromagnetic transformation is not associated with a sizeable latent heat, as confirmed by heat capacity measurements. The electronic structure calculations for [Formula: see text] indicate that the key factor in the conversion from the ferromagnetic CeScSi-type to the antiferromagnetic CeFeSi-type structure is the disappearance of the induced magnetic moments on Sc. For the parent antimonide, heat capacity measurements indicate an additional transition below the main antiferromagnetic transition.
An Ultra-Wideband Polarization Reconfigurable Slot Antenna Based on Liquid Metal (2021)

An ultra-wideband polarization reconfigurable slot antenna based on liquid metal (LM) is proposed. The Polymethylmethacrylate (PMMA) structure with microchannels are loaded on the upper and lower sides of the Rogers5880, to provide conditions for polarization reconfiguration. The left-hand circular polarization (LHCP), right-hand circular polarization (RHCP), and linear polarization (LP) are achieved by injecting LM into microchannels in different directions. The simulation results show that the proposed antenna achieves - 10dB impedance bandwidth of 81.5% (2.29-5.44GHz) in LP state, -10dB impedance bandwidth of 48.3% (2.78-4.55GHz) and 3 dB axial ratio bandwidth (ARBW) of 51.1% (2.61-4.40GHz) in CP state.
Toxicity and health effects of ultrafine particles: Towards an understanding of the relative impacts of different transport modes (2023)

Exposure to particulate matter (PM) has been associated with a wide range of adverse health effects, but it is still unclear how particles from various transport modes differ in terms of toxicity and associations with different human health outcomes. This literature review aims to summarize toxicological and epidemiological studies of the effect of ultrafine particles (UFPs), also called nanoparticles (NPs, <100 nm), from different transport modes with a focus on vehicle exhaust (particularly comparing diesel and biodiesel) and non-exhaust as well as particles from shipping (harbor), aviation (airport) and rail (mainly subway/underground). The review includes both particles collected in laboratory tests and the field (intense traffic environments or collected close to harbor, airport, and in subway). In addition, epidemiological studies on UFPs are reviewed with special attention to studies aimed at distinguishing the effects of different transport modes. Results from toxicological studies indicate that both fossil and biodiesel NPs show toxic effects. Several in vivo studies show that inhalation of NPs collected in traffic environments not only impacts the lung, but also triggers cardiovascular effects as well as negative impacts on the brain, although few studies compared NPs from different sources. Few studies were found on aviation (airport) NPs, but the available results suggest similar toxic effects as traffic-related particles. There is still little data related to the toxic effects linked to several sources (shipping, road and tire wear, subway NPs), but in vitro results highlighted the role of metals in the toxicity of subway and brake wear particles. Finally, the epidemiological studies emphasized the current limited knowledge of the health impacts of source-specific UFPs related to different transport modes. This review discusses the necessity of future research for a better understanding of the relative potencies of NPs from different transport modes and their use in health risk assessment.
Consensus-based technical recommendations for clinical translation of renal BOLD MRI (2019)

Harmonization of acquisition and analysis protocols is an important step in the validation of BOLD MRI as a renal biomarker. This harmonization initiative provides technical recommendations based on a consensus report with the aim to move towards standardized protocols that facilitate clinical translation and comparison of data across sites. We used a recently published systematic review paper, which included a detailed summary of renal BOLD MRI technical parameters and areas of investigation in its supplementary material, as the starting point in developing the survey questionnaires for seeking consensus. Survey data were collected via the Delphi consensus process from 24 researchers on renal BOLD MRI exam preparation, data acquisition, data analysis, and interpretation. Consensus was defined as ≥ 75% unanimity in response. Among 31 survey questions, 14 achieved consensus resolution, 12 showed clear respondent preference (65-74% agreement), and 5 showed equal (50/50%) split in opinion among respondents. Recommendations for subject preparation, data acquisition, processing and reporting are given based on the survey results and review of the literature. These technical recommendations are aimed towards increased inter-site harmonization, a first step towards standardization of renal BOLD MRI protocols across sites. We expect this to be an iterative process updated dynamically based on progress in the field.
Experimental study of power module with SiC devices (2011)

This paper studies the performance of a newly designed 1200V/60A three-phase SiC power module based on parallel SiC JFETs and diodes. The conduction and the switching performance are tested from room temperature to 150°C. The switching speed of the module increases when temperature rises. In the switching performance test, the gate driver speed could bring false peak in turn-off waveform. The experimental results show that the false peak is cause by Differential-mode (DM) noises but not Common-mode (CM) noises. Finally the losses and efficiency of this power module are evaluated.
Primary Hepatic Leiomyosarcoma with Giant Cyst Formation: A Case Report (2005)

A 64-year-old male with right upper abdominal pain had been treated with an H2-blocker for three months as a gastric ulcer recurrence with no response. An abdominal US identified a large cystic tumor in the left lobe of the liver. Tumor markers were all normal ; hepatitis serology tests were all negative, although liver function tests were elevated slightly. A CT scan showed a well-defined cystic tumor with a thick, heterogeneously enhanced wall. Selective celiac artery angiograms showed displacement of the common hepatic artery, and an avascular area. As a malignant tumor was suspected, a left lobectomy of the liver was performed. The tumor measured 17×15×12cm and contained central cystic degeneration filled with 280 ml of dark red fluid. Microscopic findings revealed anaplastic spindle cell proliferation, and immunohistochemical examination was positive for α-smooth muscle actin. A thorough survey did not detect a primary tumor in any other organ. Therefore, primary hepatic leiomyosarcoma was diagnosed. Only 80 cases have been reported. We reviewed the available literature.
CO2 supplementation eliminates sugar-rich media requirement for plant propagation using a simple inexpensive temporary immersion photobioreactor (2022)

Abstract In vitro plant propagation systems such as temporary immersion bioreactors (TIBs) are valuable tools that enable production of disease-free plants with improved traits. However, TIB systems can be expensive, difficult to implement, and prone to contamination due to sugar rich propagation media. Using rapidly growing chicory root cultures to expedite design-build-test cycles, we report here an improved, low-cost version of a previously reported Hydrostatically-driven TIB (Hy-TIB) that facilitates economical use of gas mixtures. Bioreactor improvements include decreased material costs, expanded modes of operation, and a horizontal orientation of a plastic film plant growth chambers that increase propagule light exposure. To take advantage of these improvements, we describe here experiments that evaluate the impacts of elevated CO 2 on propagation of cacao ( Theobroma cacao ) secondary embryos and nodal cultures of yam ( Dioscorea spp.) during both phototrophic and photomixotrophic growth. Our experiments show that elevated CO 2 during plant propagation significantly improved both cacao and yam propagule development and eliminated the need for supplemental sugars in tissue culture growth media. Thus, our improved Hy-TIB shows potential as a simple, low-cost, and scalable propagation platform with cost-effective gas composition control and reduced risk of contamination overgrowth. We provide detailed instructions for assembly of this Hy-TIB design and discuss the implications of its adoption in food-insecure regions of the world.
Effects of Rumensin Level During an Acidosis Challenge (2002)

Eighteen ruminally cannulated steers were used to determine effects of Rumensin level on incidence and severity of acidosis when an acidosis challenge was imposed. Steers received a high-concentrate finishing diet containing either 0, 30, or 45 grams/ton Rumensin. An acidosis challenge was created by feeding only 50% of diet intake one day followed by 175% of intake the next day, four hours post normal feeding time. Feeding Rumensin decreased feed intake during the prechallenge, challenge and acidosis recovery phase. Compared to 30 grams/ ton, feed intake was decreased by increasing Rumensin to 45 grams/ton during the five days following the acidosis challenge. Other feeding behavior and ruminal pH measurements were similar among treatments in all phases of this experiment. The imposed feed intake variation in this experiment did not create a significant acidosis challenge.
Active and Passive Immunization Strategies for Pseudomonas aeruginosa Pneumonia (1986)

The unusually high mortality associated with Pseudomonas aeruginosa pneumonia has provided an incentive for the development of immunologic strategies for preventing or treating this infection. A guinea pig model of experimental P. aeruginosa pneumonia was employed to determine prophylactic efficacy of active immunization with a detoxified lipopolysaccharide vaccine; efficacy of passive immune therapy utilizing a new hyperimmune immunoglobulin G preparation enriched for antibodies to P. aeruginosa immunotypes 1, 2, 4, and 6; and efficacy of active and passive immunization against the mucoid exopolysaccharide antigen associated with mucoid strains of P. aeruginosa. Each of these immunologic methods provided an element of protection against P. aeruginosa pneumonia.
A comparison of algorithms for spiral tomography (2004)

The paper deals with the three-dimensional transmission tomography problem. The projection geometry with a source moving along a spiral is investigated. Three reconstruction algorithms are compared quantitatively. The main attention is paid to the comparison of the algorithms based on the equations of quasi-exact inversion with the approximate iterative method ART. The known algorithms are modified to be more stable with respect to noise. The recommendations how to choose an optimal algorithm for different projection schemes are proposed.
Co-extrusion of Dual Aluminum Alloys with Special Surface Properties (2017)

Co-extrusion method is used for production of a dual Aluminum rod. The surface layer material for co-extrusion is prepared by rapid solidification process. The alloys Al-4.5Mg-1.0Ag (wt%) and Al-4.5Mg are selected as the surface and the bulk materials, respectively, and are co-extruded at high temperature range (450-480°C). The microstructures of rapid solidified Al in co-extruded rod consist of small grains (50µm) and some small particles (0.1-1µm). A proper annealing on the extruded rod increases the surface hardness more than 30%. Since the co-extruded material contains small T-phase particles, this increase in hardness indicates precipitation of a metastable Mg-Ag phase or a Mg-Ag-Al phase at 160°C during annealing.

HIV infection in women: an escalating health concern. (1996)

The proportion of women infected with the human immunodeficiency virus (HIV) continues to increase. Over one-half of women acquire the virus through heterosexual contact. The diagnoses that define the acquired immunodeficiency syndrome and the use of antiretroviral therapy are similar in men and women, except in pregnancy. However, management decisions differ significantly regarding contraceptive and gynecologic care. Besides abstinence, use of the latex condom continues to be the most effective way of preventing transmission of HIV. The management of human papillomavirus-associated disease, pelvic inflammatory disease and vaginal candidiasis is especially challenging in women with HIV infection. A positive status for the virus does not appear to affect pregnancy outcome. Each year, up to 2,000 infants are born infected with HIV. Transmission can occur by transplacental or intrapartum spread or through breast milk. Since 1994, prophylaxis with zidovudine has been shown to be an effective method of limiting transmission to infants. It is important to offer all pregnant women a test for HIV, with counseling provided both before and after the test, even if testing does not become mandatory under the law.
Antenna subset selection for spatial modulation: A novel and energy efficient single RF technique (2013)

In this paper, we propose a closed-loop and single RF multiple-input-multiple-output (MIMO) method, particularly suitable for the Uplink of cellular systems, which is based on the low-complexity and recently devised method of Spatial Modulation. By selecting a subset of the available transmit antennas to implement Spatial Modulation based on the instantaneous Bit Error Rate (BER), the proposed method achieves both multiplexing and transmit-diversity gains by utilizing only one RF chain. By taking into account the total power consumption at the transmit side, we numerically show that our proposed method is more energy efficient than the single RF transmit antenna selection method for the same target performance and several MIMO configurations and correlation values among the transmit antennas.
Scanning mirror microscope with optical sectioning characteristics: applications in ophthalmology (1980)

Optical sectioning is the simultaneous illumination and viewing of only a thin region of a specimen. An illuminated slit is imaged at the plane of interest and is swept laterally by the action of an oscillating mirror. The light returning from the specimen reflects from a second facet of the oscillating mirror and forms a stationary image of the illuminated slit. At this stationary image a second slit is placed, which passes light from the desired plane and rejects scattered light from other depths within the specimen. Light passing through the second slit is reflected from the third facet of the oscillating mirror and is focused to the final image plane. The image is reconstructed as the image of the second slit sweeps across the image plane. An important ophthalmological application is the examination of the endothelial cell layer of the cornea, either by contact or noncontact techniques. Optimization for image illuminance and resolution is discussed.

Acrylic block copolymer analysis by adsorption chromatography with evaporative light scattering detection (1991)

Abstract Block copolymers of methyl methacrylate and butyl methacrylate are characterized using silica adsorption chromatography with a toluene‐2‐butanone solvent gradient. Evaporative light scattering is the detection method for these otherwise hard to detect acrylic polymers. The homopolymer contamination in the diblock materials are well resolved from the diblock in the separation. The major separation mechanism is composition controlled, but the results also indicate a block length dependency on the separation mechanism.
