Left Atrial and Ventricular Filling in Chronic Obstructive Pulmonary Disease (2000)

Abnormal left ventricular (LV) diastolic function has frequently been reported in patients with chronic obstructive pulmonary disease (COPD). In the present work, diastolic function was studied by a combined analysis of pulmonary venous and mitral blood flow velocities in 34 patients with COPD clinically stable and without history of heart disease, and 20 control subjects. We confirmed the increased contribution of the atrial contraction to the LV filling in COPD patients in comparison with control subjects; furthermore, a decreased left atrial (LA) filling during the ventricular systole was observed. Changes in LV filling were not the consequence of a systolic dysfunction, because LV systolic function was normal. Doppler indices indicated that LA pressure was below 15 cm H(2)O in all the patients with COPD and control subjects. Several factors can be put forward to explain these changes; the first one is tachycardia. In addition to hypoxemia and medications, echocardiography suggested that a decreased LV preload participated in increased heart rate. Analysis of Doppler transmitral and pulmonary venous flows demonstrated the role of the ventricular interdependence because a correlation existed between LA and LV filling pattern and right ventricle pressure and diameter.
A study of silicon MBE on porous silicon substrates (1985)

The defect structure of Si MBE layers grown on porous silicon substrates depends critically on the technique for cleaning the substrate surface. Cross-sectional TEM studies demonstrate that a combined sputter-clean and thermal cycle markedly reduces the density of microtwins and dislocations in the epitaxial layer when compared with simple thermal cleaning. X-ray diffraction studies show the porous silicon layer to be lattice-matched to the underlying (100) bulk silicon substrate in the plane of the wafer so that misfit dislocations are not expected in the epitaxial layer. However, both the lattice parameter of the porous layer in the direction normal to the wafer and the thermal stability of the porous layer in vacuum, depend upon the resistivity of the starting wafer. The photoluminescence of a 4-μm MBE layer grown on a sputter-cleaned, high resistivity substrate is still dominated by recombination at dislocations.
Upregulation of AT<sub>2</sub> receptor and iNOS impairs angiotensin II-induced contraction without endothelium influence in young normotensive diabetic rats (2008)

Diabetes and insulin resistance are associated with an increased risk of hypertension and cardiovascular disease. Recent evidence demonstrates that AT2 receptors (AT2R) play an important role in the hemodynamic control of hypertension by vasodilation. The quantitative significance of AT2R in the establishment of diabetic vascular dysfunction, however, is not well defined and needs further investigation. Goto-Kakizaki (GK) rats, a polygenic model of spontaneous normotensive type 2 diabetes, were used to examine any abnormalities in cardiovascular function associated with AT2R at the early stage of the disease without endothelium influence. Using a myograph to measure the isometric force, we observed that ANG II-induced contraction was impaired in denuded GK aorta compared with control Wistar-Kyoto (WKY) aorta and exhibited a retarded AT1R antagonist response and enhanced Rho kinase signaling. When AT1R were blocked, ANG II induced a significant vasodilation of precontracted GK aorta via AT2R. The protein and mRNA of AT2R were increased in diabetic GK denuded aorta. Blocking AT2R restored the ANG II-induced contraction in the GK vasculature to control levels, demonstrating a counteractive role for AT2R in AT1R-induced contraction. Inhibition of inducible nitric oxide synthase (iNOS) by NG-monomethyl-L-arginine mimicked AT2R inhibition in denuded GK aorta, suggesting that AT2R-induced vasodilation was dependent on iNOS/NO generation. The protein and mRNA of iNOS were also increased in GK aorta. In conclusion, these results clearly demonstrate that enhanced AT2R and iNOS-induced, NO-mediated vasodilation impair ANG II-induced contraction in an endothelium-independent manner at the early stage of type 2 diabetes.

Effectiveness of Jet‐Cooked Pearl Cornstarch as a Controlled Release Matrix (1987)

Abstract The effectiveness of non‐chemically modified pearl cornstarch as an encapsulating matrix for active agents such as herbicides is reported. Aqueous gelatinization of pearl cornstarch at high temperatures followed by active agent addition, drying and grinding yielded encapsulated products showing slow release of active agent. Efficiency of encapsulation and rate of release of the herbicide butylate varied with temperature and concentration of starch during steam‐jet cooking, amount of butylate incorporated and method of drying. Retrogradation is the major factor influencing efficiency of encapsulation and rate of active agent release.
A concentrated parameter model for the human cardiovascular system including heart valve dynamics and atrioventricular interaction (2005)

Numerical modeling of the human cardiovascular system has always been an active research direction since the 19th century. In the past, various simulation models of different complexities were proposed for different research purposes. In this paper, an improved numerical model to study the dynamic function of the human circulation system is proposed. In the development of the mathematical model, the heart chambers are described with a variable elastance model. The systemic and pulmonary loops are described based on the resistance-compliance-inertia concept by considering local effects of flow friction, elasticity of blood vessels and inertia of blood in different segments of the blood vessels. As an advancement from previous models, heart valve dynamics and atrioventricular interaction, including atrial contraction and motion of the annulus fibrosus, are specifically modeled. With these improvements the developed model can predict several important features that were missing in previous numerical models, including regurgitant flow on heart valve closure, the value of E/A velocity ratio in mitral flow, the motion of the annulus fibrosus (called the KG diaphragm pumping action), etc. These features have important clinical meaning and their changes are often related to cardiovascular diseases. Successful simulation of these features enhances the accuracy of simulations of cardiovascular dynamics, and helps in clinical studies of cardiac function.
Isolation of a virus infectious to the harmful bloom causing microalga Heterosigma akashiwo (Raphidophyceae) (1997)

A virus infecting the harmful bloon~ causing microalga Heterosjgma akashiwo (Raphidophyceae) was isolated from the coastal water of Nomi Bay, Japan, In July 1996. The isolate caused lysis in 2 strains of H. akashiwo tested and numerous virus-like particles (VLPs) appeared in the lysed algal culture, whereas virus multiplication was not detected in the healthy culture of H. akashiwo without its inoculation. Thus, fulfilhng Koch's postulate, it was considered to be a virus and designated HaV (Heterosigma akashiwo virus) clone GSNOU-30 The virus particle is icosahedral, lacking a tail, and 202 * 6 nm (average * standard deviation) in diameter with an electron-dense roundish core that is distinct from the capsid. The vlrus stained positive with DAPI, indicating that it possesses a double stranded DNA genome. The virus proliferated in the protoplasm of the host cell as had previously been observed in H. akashiwo cells from a natural red tide population. The virus did not cause lysis of Chattonella antiqua, C. verruculosa or Fibrocapsa japonica (Raphidophyceae) as well as 15 strains of phytoplankton belonging to other classes. It is most noteworthy that 3 strains of H. akashjwo isolated from Hiroshima Bay, Japan, were resistant to GSNOU-30, suggesting that the viral infectivity is not species-specific but strain-specific. These results suggest that the virus is involved in the population dynamics of H. akashjwo, playing a role as a selector to increase genetic diversity of a host species.
A genetic algorithm for job shop (2002)

Genetic algorithms (GAs) constitute a technique that has been applied with advantage to a variety of combinatorial problems. This work shows how the GAs can be used to optimize the job shop problem with many tasks, many machines, and precedence constraints. The authors introduce the technique of GAs and then show what makes the treatment of the job shop scheduling difficult. They then present an encoding of the problem that overcomes these difficulties. The performance of the algorithm is demonstrated with examples of real-world size.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A 60 GHz Planar Diplexer Based on Substrate Integrated Waveguide Technology (2013)

This paper presents a millimeter-wave, 60 GHz frequency band planar diplexer based on substrate integrated waveguide (SIW) technology. Diplexer consists of a pair of 5th-order SIW bandpass channel filters with center frequencies at 59.8 GHz and 62.2 GHz providing 1.67% and 1.6% relative bandwidths, respectively. SIW-to-microstrip transitions at diplexer ports enable integration in a millimeter-wave transceiver front end. Measurements are in good agreement with electromagnetic simulation, reporting very good channel isolation, small return losses, and moderate insertion losses in the passbands. The proposed SIW planar diplexer is integrated into a millimeter-wave transceiver front end for 60 GHz point-to-point multigigabit wireless backhaul applications, providing high isolation between transmit and receive channels.
Surface Impedance of Thin Superconducting Films (1962)

Theoretical analysis and experimental measurements have been made of the propagation of electromagnetic waves in a structure consisting of two planar superconductors which are of the order of a penetration depth apart. One superconductor is tantalum and is much thicker than a penetration depth; the other is a vacuum evaporated indium film and may be as thin as a penetration depth. It is shown that such a structure will propagate waves at a phase velocity less than the speed of light in the medium separating the superconductors, a phenomenon that is the result of an inductive component in the surface impedance of the superconductors. The exact velocity is shown to be a function of the thickness parameters in a manner which depends on the law relating the vector potential and the supercurrent in the indium. Experimental measurements indicate that the relationship between vector potential and current in the vacuum evaporated indium is characterized by a coherence distance which is considerably smaller than that found for pure metals by the measurements of Pippard and the theory of Bardeen, Cooper and Schrieffer. The penetration depth at zero temperature is deduced from dependence of phase velocity on the thicknesses of the indium and dielectric. For indium λ is found to be 650 ± 75A, in good agreement with Lock's value of 640A and Toxen's range from 625 to 725A. For tantalum λ is found to be 500 ± 175A. This is believed to be the first measurement. The value of λ for indium is also deduced from the dependence of phase velocity on temperature. It is found to be 704 ± 120A. Surface resistance of the two superconductors is found to increase ω2, in good agreement with theory, and to depend on temperature according to an empirical law proposed by Pippard.
Thermal Neutron Activation Analysis of Vanadium and Manganese in Ginseng using 3.76-Minute Vanadium-52 and 2.58 Hour Manganese-56 (1963)

Thermal neutron activation analysis was applied to determine the trace amount of Vanadium and Manganese in Buyo and Kumsan Ginseng. These elements have been regarded to have great nutritional value and one of the indispensable factor in the growth of ginseng. The TRIGA MARK II Reactor in Atomic Energy Research Institute was used for the neutron source. The samples were irradiated for 10 minutes for Vanadium and for 5 minutes for Manganese at the neutron flux of about and the RCL 256 Channel Pulse-Height Analyzer connected with Nal(Tl) was used for activity determination. The amounts were about 0.02 ppm for Vanadium and 20 ppm for Manganese, and it was also found that the amounts of the elements were slightly different depending on the kinds of ginsengs.

Genetic Characterization and Evolutionary Implications of a <i>car</i> Gene Cluster in the Carbazole Degrader <i>Pseudomonas</i> sp. Strain CA10 (2001)

The nucleotide sequences of the 27,939-bp-long upstream and 9,448-bp-long downstream regions of the carAaAaBaBbCAc(ORF7)Ad genes of carbazole-degrading Pseudomonas sp. strain CA10 were determined. Thirty-two open reading frames (ORFs) were identified, and the car gene cluster was consequently revealed to consist of 10 genes (carAaAaBaBbCAcAdDFE) encoding the enzymes for the three-step conversion of carbazole to anthranilate and the degradation of 2-hydroxypenta-2,4-dienoate. The high identities (68 to 83%) with the enzymes involved in 3-(3-hydroxyphenyl)propionic acid degradation were observed only for CarFE. This observation, together with the fact that two ORFs are inserted between carD and carFE, makes it quite likely that the carFE genes were recruited from another locus. In the 21-kb region upstream from carAa, aromatic-ring-hydroxylating dioxygenase genes (ORF26, ORF27, and ORF28) were found. Inductive expression in carbazole-grown cells and the results of homology searching indicate that these genes encode the anthranilate 1,2-dioxygenase involved in carbazole degradation. Therefore, these ORFs were designated antABC. Four homologous insertion sequences, IS5car1 to IS5car4, were identified in the neighboring regions of car and ant genes. IS5car2 and IS5car3 constituted the putative composite transposon containing antABC. One-ended transposition of IS5car2 together with the 5' portion of antA into the region immediately upstream of carAa had resulted in the formation of IS5car1 and ORF9. In addition to the insertion sequence-dependent recombination, gene duplications and presumed gene fusion were observed. In conclusion, through the above gene rearrangement, the novel genetic structure of the car gene cluster has been constructed. In addition, it was also revealed that the car and ant gene clusters are located on the megaplasmid pCAR1.
Neutrophil-related factors as biomarkers in EAE and MS (2015)

A major function of T helper (Th) 17 cells is to induce the production of factors that activate and mobilize neutrophils. Although Th17 cells have been implicated in the pathogenesis of multiple sclerosis (MS) and the animal model experimental autoimmune encephalomyelitis (EAE), little attention has been focused on the role of granulocytes in those disorders. We show that neutrophils, as well as monocytes, expand in the bone marrow and accumulate in the circulation before the clinical onset of EAE, in response to systemic up-regulation of granulocyte colony-stimulating factor (G-CSF) and the ELR(+) CXC chemokine CXCL1. Neutrophils comprised a relatively high percentage of leukocytes infiltrating the central nervous system (CNS) early in disease development. G-CSF receptor deficiency and CXCL1 blockade suppressed myeloid cell accumulation in the blood and ameliorated the clinical course of mice that were injected with myelin-reactive Th17 cells. In relapsing MS patients, plasma levels of CXCL5, another ELR(+) CXC chemokine, were elevated during acute lesion formation. Systemic expression of CXCL1, CXCL5, and neutrophil elastase correlated with measures of MS lesion burden and clinical disability. Based on these results, we advocate that neutrophil-related molecules be further investigated as novel biomarkers and therapeutic targets in MS.
Return-Oriented Programming (2012)

Attackers able to compromise the memory of a target machine can change its behavior and usually gain complete control over it. Despite the ingenious prevention and protection mechanisms that have been implemented in modern operating systems, memory corruption attacks still account for a big share of the security breaches afflicting software systems. This article describes a growing attack trend that uses return-oriented programming (ROP) techniques to bypass the most common memory protection systems.

A new method for estimation of coronary artery dimensions in angiograms (1988)

A novel approach is presented for the measurement of the severity of coronary obstructions from coronary angiograms. The proposed approach exploits the characteristics of the signals involved. A model of the film density of the densitometric profiles of lines crossing the vessel is developed and used to estimate the diameter and cross-sectional area at each point along the vessel. The model accounts for the structure of the vessel and background, as well as the distortions introduced by the imaging system. The algorithms are tested on synthetic data, on X-rays of contrast-medium-filled cylindrical phantoms, and on real coronary angiograms. The algorithms are shown to have better performance than current methods.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Data fusion in multi sensor platforms for wide-area perception (2006)

There is a strong belief that the improvement of preventive safety applications and the extension of their operative range are achieved by the deployment of multiple sensors with wide fields of view (FOV). The paper contributes to the solution of the problem and introduces distributed sensor data fusion architectures and algorithms for an efficient deployment of multiple sensors that give redundant or complementary information for the moving objects. The proposed fusion architecture is based on a modular approach allowing exchangeability and benchmarking using the output of individual trackers, whereas the fusion algorithm gives a solution to the track management problem and the coverage of wide perception areas. The test case is LATERAL SAFE sensor configuration, which monitors the rear and lateral areas of the vehicle. Results show that with the given approach the system is able to maintain the ID of all objects in transition (an object enters a sensor's FOV) and blind areas (no sensor coverage)
n-3 Fatty Acids Specifically Modulate Catabolic Factors Involved in Articular Cartilage Degradation (2000)

This study describes specific molecular mechanisms by which supplementation with n-3 fatty acids (i.e. those present in fish oils) can modulate the expression and activity of degradative and inflammatory factors that cause cartilage destruction during arthritis. Our data show that incorporation of n-3 fatty acids (but not other polyunsaturated or saturated fatty acids) into articular cartilage chondrocyte membranes results in a dose-dependent reduction in: (i) the expression and activity of proteoglycan degrading enzymes (aggrecanases) and (ii) the expression of inflammation-inducible cytokines (interleukin (IL)-1alpha and tumor necrosis factor (TNF)-alpha) and cyclooxygenase (COX-2), but not the constitutively expressed cyclooxygenase COX-1. These findings provide evidence that n-3 fatty acid supplementation can specifically affect regulatory mechanisms involved in chondrocyte gene transcription and thus further advocate a beneficial role for dietary fish oil supplementation in alleviation of several of the physiological parameters that cause and propogate arthritic disease.
