A surface-micromachined shear stress imager (2002)

A new MEMS shear stress sensor imager has been developed and its capability of imaging surface shear stress distribution has been demonstrated. The imager consists of multi-rows of vacuum-insulated shear stress sensors with a 300 /spl mu/m pitch. This small spacing allows it to detect surface flow patterns that could not be directly measured before. The high frequency response (30 kHz) of the sensor under constant temperature bias mode also allows it to be used in high Reynolds number turbulent flow studies. The measurement results in a fully developed turbulent flow agree well with the numerical and experimental results previously published.
Effects of Atriopeptidase Inhibitor UK 79300 on Left Ventricular Hydraulic Load in Patients With Congestive Heart Failure (1991)

We investigated effects of the first orally active atriopeptidase inhibitor UK 79300 (Pfizer Clinical Research, UK) on left ventricular hydraulic load in patients with congestive heart failure NYHA II and III. In our study, 6 patients received 200 mg and 4 patients received 400 mg of UK 79300, and 4 patients received placebo (controls). Before and 90 min after oral administration of UK 79300 or placebo aortic input impedance was assessed to characterize left ventricular hydraulic load. Plasma levels of atrial natriuretic peptide (ANP) significantly increased by 126% after 200 mg and by 141% after 400 mg of UK 79300, but remained unchanged in control patients. Mean arterial pressure and flow, resistive term, characteristic impedance and oscillatory aortic input pressure power showed minor changes without statistical significance on an intergroup comparison. We conclude that acute atriopeptidase inhibition by UK 79300 effectively increases endogenous ANP levels up to 2.5-fold. However, these changes were not accompanied by significant effects on left ventricular hydraulic load.
Strain Development in Streptomyces virginiae, a Producer of Virginiamycyn (1987)

Click to increase image sizeClick to decrease image sizeРЕЗЮМЕStreptomyces virginiae ATCCI3161 продуцират комплекс от антибиотици, които се състоят от цикличии лактонови пептолиди (виргиниамицин М и S) и свързани съединения.Популациите шамове се развиваха на органична среда и образуваха два типа колvнии—А и В,коитосе различаваха по цвета на повърхността си (сив и бял, съответно) и по способността си да формират дифундиращ пигмент. Получените чрез мутация и селекция щамове притежаваха способноет да продуцират на повисоко ниво виргиниамицин Ml; при тип В възможността за химично от деляне на антибиотика беше по-голяма, поради значителиото намаляване на продукцията на други компоненти в комплекса. По-нататъшното повишаване на добива на Мl компонента беше постигнато чрез промени в технологмята на ферментация. Заедно с това бе отделена група мутанти, които не притежаваха антибиотични свойства.РЕЗЮМЕStreptomyces virginiae А ТСС 13161 продуцирует комплекс антибиотиков, состоящий из циклических лактоновых пептолидов (виргиниамицин М и S) и связанных соединений. Популяции штаммов, выросших на органической среде, образуют 2 типа колоний—А и В, различающихся по цвету поверхности (серые и белые соответственно) и способности образовывать темный диффундирующий пигмент. С помощью мутагенеза и селекции получены штаммы с повышенным уровнем продуцирования вирrиниамицина м 1 независимо из штоков А и В; тип В был более приемлем для химического выделения антибиотика вследствие значительно меньшего продуцирования других компонентов комплекса. Усовершенствованием технологии ферментирования было достигнуто дальнейшее увеличение выхода компонента М 1. Помимо этого была выделена группа стоп мутаций, вызывающих накопление соединений, не обладающих антибиотичными свойствами.
Polymorphisms in Ghrelin and Neuropeptide Y Genes Are Associated with Non-Hodgkin Lymphoma (2005)

We previously reported a positive association among body mass index, single nucleotide polymorphisms (SNP) in the leptin and leptin receptor genes that are involved in body weight regulation, and non-Hodgkin lymphoma (NHL). Polymorphisms in the ghrelin (GHRL) and neuropeptide Y (NPY) genes were examined in the same population-based case-control study of NHL to further explore the role of genes involved in energy homeostasis and obesity in susceptibility to NHL. Ghrelin is an orexigenic hormone that induces NPY release and inhibits proinflammatory cytokines via its antagonistic relationship with leptin. NPY is a potent appetite stimulator controlled by ghrelin and leptin and also acts as a mediator of immune function. DNA from 458 cases and 812 controls was genotyped. Among genotyped GHRL SNPs, the variant allele for GHRL -4427G>A was inversely associated with all NHL [odds ratios (OR), 0.78; 95% confidence interval (95% CI), 0.59-1.0] and more specifically with diffuse large cell lymphoma (DLCL; homozygous variant: OR, 0.31; 95% CI, 0.13-0.74). Another SNP, GHRL 5179A>G, decreased the risk of DLCL (homozygous variant: OR, 0.35; 95% CI, 0.10-1.2). NPY -485T>C, 1258G>A, and 5671C>T were in total linkage disequilibrium (D' = 0.99) and the homozygous variants were associated with an increased risk of NHL in NPY SNPs -485T>C (OR, 1.7; 95% CI, 1.1-2.5), 1258G>A (OR, 1.7; 95% CI, 1.1-2.5), and 5671C>T (OR, 1.9; 95% CI, 1.3-2.8). When stratified by subtype, the variant allele for NPY 1128T>C was positively associated with follicular lymphoma (OR, 2.3; 95% CI, 1.1-4.9) as were homozygous variants for NPY SNPs -485T>C (OR, 2.4; 95% CI, 1.3-4.4), 1258G>A (OR, 2.0; 95% CI, 1.1-3.5), and 5671C>T (OR, 1.8; 95% CI, 1.1-3.0). These results add further support for the hypothesis that SNPs in energy-regulating genes affect risk of NHL.
Pre‐operative nutritional support in children with end‐stage liver disease accepted for liver transplantation: An approach to management (1990)

Pre-operative nutritional support was studied in 28 children with end-stage liver disease awaiting orthotopic liver transplantation. Nasogastric supplemental administration of a standard semi-elemental enteral nutritional formula was compared with a similar formula enriched with branched chain amino acids, and with a group receiving oral nutrition only. The duration of treatment in all groups was similar (mean 90 days). Energy intakes in the supplemented groups were 120-150% of recommended daily intakes (RDI), whereas ad libitum intakes in the oral group ranged 58-100% RDI. A significant improvement in mean Z-score for body weight (denoting catch-up) was noted only in those children who received nasogastric supplements enriched with branched-chain amino acids. The standard enterally-fed group maintained their body weight and Z-scores did not change significantly. In contrast, body weight Z-scores in those fed orally declined significantly. Nutritional supportive therapy of malnourished children with end-stage liver disease can minimize or improve nutritional status in children awaiting liver transplantation. The use of nutritional formulae rich in branched-chain amino acids may have nutritional advantages in children with chronic liver disease which require further study and evaluation.
Specificity of human beta-choriogonadotropin assays for the hormone and for an immunoreactive fragment present in urine during normal pregnancy. (1983)

We evaluated four high-purity commercial preparations of human choriogonadotropin (hCG; Boehringer-Mannheim, Calbiochem, Cambridge, and Radioassay Systems) by two radioimmunoassays and one radioreceptor procedure. Their specific activities were less than half that of the first International Reference Preparation of hCG for immunoassay. In addition, a fragment that was immunoreactive in radioimmunoassays for hCG with antisera to the beta-subunit conformational determinant was isolated from crude hCG (Roussel Corp.). The fragment adsorbed to concanavalin A and exhibited a relative molecular mass of 12 000 by gel filtration. In a study with 94 urines from women three to 24 weeks pregnant, the fragment contributed more than 70% of the immunoreactivity detected by the above radioimmunoassays for hCG in 70% of the samples. The fragment was present in urine throughout pregnancy, but was not detected in the serum of any of seven pregnant women tested.
Immunofluorescent staining of the surfaces of lymphocytes in suspension from patients with dengue hemorrhagic fever. (1976)

Immunofluorescent staining of lymphocytes suspensions from 55 of 62 patients with dengue hemorrhagic fever was positive for dengue antigen and human beta1C/a-globulin on the surface, from the second ay before shock or subsidence of fever. The percentages of positive staining of both components gradually increased to a maximum on the day of shock or subsidence of fever. B lymphocytes increased during the course of the disease. Neither dengue antigen nor human beta1C/a-globulin was detected on the surface of the lymphocytes from normal controls or patients with other diseases. By double immunofluorescent staining with different colors of fluorochromes, antidengue antibody with fluorescein isothiocyanate and antihuman gamma -globulin or antihuman beta1C/a-globulin with lissamine rhodamine B on the same lymphocytes revealed dengue antigen appearing only on B lymphocytes. The human beta1C/a-globulin and dengue antigen were located on the surface of the same lymphocytes. The pattern of the staining by both components showed fine and coarse irregular granules over the lymphocyte surface. The fluorescent granules seemed to be on the surface but not in the intracellular vacuoles of the lymphocytes.
Flux Pumping Effect of HTS Films in a Traveling Magnetic Field (2010)

This paper reports the possibility of High Temperature Superconductor (HTS) magnetic flux pump for the compensation of slight current decay in persistent mode HTS magnet. As a first step, the linear type magnetic flux pump (LTMFP) is fabricated with the use of the wound BSCCO tapes, and then the preliminary pumping test is carried out by using NbTi load coil in liquid helium. Further, the current transport property of the produced MgB <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> thin films is measured, and then the fabrication of the LTMFP has been completed for the purpose of the higher performance as well as higher temperature (e.g., 20 K) operation.
Structural and Enzymatic Analysis of MshA from Corynebacterium glutamicum (2008)

The glycosyltransferase termed MshA catalyzes the transfer of N-acetylglucosamine from UDP-N-acetylglucosamine to 1-L-myo-inositol-1-phosphate in the first committed step of mycothiol biosynthesis. The structure of MshA from Corynebacterium glutamicum was determined both in the absence of substrates and in a complex with UDP and 1-L-myo-inositol-1-phosphate. MshA belongs to the GT-B structural family whose members have a two-domain structure with both domains exhibiting a Rossman-type fold. Binding of the donor sugar to the C-terminal domain produces a 97 degrees rotational reorientation of the N-terminal domain relative to the C-terminal domain, clamping down on UDP and generating the binding site for 1-L-myo-inositol-1-phosphate. The structure highlights the residues important in binding of UDP-N-acetylglucosamine and 1-L-myo-inositol-1-phosphate. Molecular models of the ternary complex suggest a mechanism in which the beta-phosphate of the substrate, UDP-N-acetylglucosamine, promotes the nucleophilic attack of the 3-hydroxyl group of 1-L-myo-inositol-1-phosphate while at the same time promoting the cleavage of the sugar nucleotide bond.
Stereospecific polymerization of cyclobutene (1963)

Abstract The polymerization of cyclobutene in the presence of catalytic systems, prepared from transition metal compounds of the 3rd to the 8th group of the periodic table and organometallic compounds, is studied. The stereospecific polymerization to crystalline polymers having polycyclobutylene structure occurs preferably with vanadium or chromium—based catalysts. The chemical and physico‐chemical structure determination and the analogies with the polymerizations of α‐olefins and butadiene allow to make probable, for the two types of polycyclobutylenes, an erythro di‐isotactic and respectively erythro di‐syndiotactic structure.
Pyroelectric properties of flexible PZT composites (1980)

Abstract The pyroelectric properties of flexible composite ceramics made from a mixture of niobium doped lead zirconate lead titanate particles and silicone rubber are reported. These are then compared to a conventional dense piezoelectric ceramic. The pyroelectric coefficients were determined to be 0.6 to 2.0 × 10−2 vs 4.9 × 10−8 coul/cm2°C for the dense PZT ceramics. The pyroelectric response of the flexible composites were about five times greater than the dense ceramic. A method is described for manipulating the pyroelectric coefficient and response of these materials.
Contradictory functions of sulfatide in the blood coagulation system as coagulant and anticoagulant. (1998)

Sulfatide (galactosylceramide I3 -sulfate) has been reported to activate blood coagulation factor XII (Hageman factor), which suggests that it exhibits coagulant activity (Fujikama et al., 1980 Biochemistry 19, 1322-1330) However, sulfatide administered into animals as a bolus shot without subsequent thrombus formation, prolonged conventional clotting times and bleeding time (Hara et al., 1996 Glycoconjugate J. 13, 187-194). These findings suggest that it may exhibit anticoagulant rather than coagulant activity. Following this suggestion we found in vitro that binding of sulfatide to fibrinogen resulted in disturbance of fibrin formation. To examine a possible pharmacological effect of sulfatide on blood coagulation in vivo we continuously infused sulfatide into rats through plastic cannulae and found formation of giant thrombi around the tips of the cannulae. These data suggest that sulfatide may exhibit contradictory functions in the blood coagulation system.
Vertical-cavity surface-emitting laser diodes with post-growth wavelength adjustment (2002)

We developed a novel vertical-cavity surface-emitting laser (VCSEL) structure with a hybrid top mirror consisting of a semiconductor DBR, an oxide layer, and a metal reflector enabling the post-growth determination of the emission wavelength of individual elements in a 2D laser array using anodic etching. The devices should prove to be useful for all-optical switching, free-space communication, and wavelength division multiplexing systems.

Na/K/Cl cotransport in cultured human fibroblasts. (1985)

The transport characteristics and regulation of the Na/K/Cl cotransport system were investigated in cultured human fibroblasts (HSWP cells). The existence of the system was documented by the finding that digitoxin-insensitive K+ influx was dependent upon the presence of both Na+ and Cl- in the extracellular milieu. It was found that only Br- could partially substitute for Cl-, with SCN-, I-, acetate, and gluconate being ineffective. Li+ could partially substitute for Na+; however, choline was without effect. The shape of the titration curves for K+ influx versus extracellular Cl- concentration was dependent upon the substituted anion. Furthermore, the apparent Km for Cl- at saturating [K+]o and [Na+]o, was also dependent upon the substituted anion and ranged from 30 mM (gluconate substitution) to 100 mM (acetate substitution). The titration curves for K+ influx versus extracellular Na+ concentration displayed hyperbolic kinetics and the apparent Km = 15 mM at saturating [K+]o. The curve for K+ influx versus extracellular K+ concentration was a hyperbola and the apparent Km for K+ = 3 mM at saturating [Na+]o. The digitoxin-insensitive K+ flux was found to be sensitive to related 5-sulfamoylbenzoic acid derivatives, commonly known as "loop" diuretics and to be insensitive to both: amiloride (3,5-diamino-N-(aminoiminomethyl)-6-chloropyrazinecarboxamide++ +) and 4-acetamido-4'-isothiocyanostilbene-2,2'-disulfonic acid. The Na/K/Cl cotransport system was not stimulated by serum, but was slightly stimulated by two peptide mitogens. Furthermore, agents which cause an elevation in cellular cyclic AMP levels were found to be potent inhibitors of cotransport.
Killing of Saccharomyces cerevisiae by the lysosomotropic detergent N-dodecylimidazole (1987)

The lysosomotropic detergent N-dodecylimidazole (C12-Im) has previously been found to kill mammalian cells by concentrating in lysosomes, followed by lysosomal disruption and release of cytotoxic enzymes into the cytoplasm. The action of C12-Im on Saccharomyces cerevisiae is described in this report. C12-Im prevented growth of colonies when present in 1% yeast extract-2% Bacto-Peptone-2% glucose plates at concentrations of 5 micrograms/ml or above, or when present in a soft agar overlay at 20 micrograms/ml. Treatment of cells suspended in glucose-containing buffer (pH 8.0, 37 degrees C) with C12-Im (6 micrograms/ml) caused greater than 95% cell death within 6 min. Dependence of killing on C12-Im concentration was sigmoidal, suggesting a cooperative mode of action. Killing was pH dependent, being much more effective at pH 8.0 than at pH 5.0. Ammonium sulfate and imidazole protected against killing if added before, but not after, the addition of C12-Im. Sensitivity to C12-Im was strongly growth dependent: the cells were most sensitive at early to mid-logarithmic phase of growth and became progressively less sensitive during progression through late logarithmic and stationary phase. Vacuolar disruption by C12-Im was demonstrated by using cells loaded with lucifer yellow CH or fluoresceinated dextran in their vacuoles; vacuoles of logarithmically growing cells were more sensitive than those of stationary-phase cells. These results suggest that vacuolar disruption by C12-Im may underlie its cytotoxic effects.
Study of shot length and motion as contributing factors to movie tempo (poster session) (2000)

This work seeks to lay the framework of film grammar over the video to be analysed. We use the shot attributes of motion and shot length to produce a novel continuous measure of one of the aesthetic elements of films, namely the movie tempo. We refer to our previous work detailing the study of this construct and its automatic derivation, and also demonstrating its usefulness as an expressive element and as a sound basis for higher semantic descriptions such as dramatic events and story elements. Initial assessment of tempo was performed in our study on the basis that the relative importance of both shot length and motion in formulating the tempo function was the same. In this paper, we analyze their relative contributions to tempo, and demonstrate how these two factors can be manipulated to influence audience perception of movie time.

Systems Integration, Modeling, and Validation of a Fuel Cell Hybrid Electric Vehicle (2000)

The goals of the research documented in this thesis were the design, construction, modeling, and validation of a fuel cell hybrid electric vehicle based a conversion of a five-passenger production sedan. Over 60 engineering students working together as the Hybrid Electric Vehicle Team of Virginia Tech (HEVT), integrated a proton exchange membrane fuel cell system into a series hybrid electric vehicle. This design produced an efficient and truly zero-emission vehicle. This 1997 Chevrolet Lumina sedan, renamed ANIMUL H2, carries this advanced powertrain, using an efficient AC induction drivetrain, regenerative braking, compressed hydrogen fuel storage, and an advanced lead-acid battery pack for peak power load leveling. The vehicle weighed 2000 kg (4400 lb) and achieved a combined city/highway fuel economy of 9L/100 km or 26 mpgge (miles per gallon gasoline equivalent, charge depleting, state of charge corrected). A model of the vehicle was developed using ADVISOR, an Advanced Vehicle Simulator that tracks energy flow and fuel usage within the vehicle drivetrain and energy conversion components. The vehicle was tested using the Environmental Protection Agency city and highway driving cycles to provide data for validation of the model. Vehicle data and model results show good correlation at all levels and show that ADVISOR has the capability to model fuel cell hybrid electric vehicles. To make techniques proven by this work more versatile for real world application, VT worked with engineers at the National Renewable Energy Laboratory to develop a 'generic' version of this fuel cell system model that was released to the public in ADVISOR 2.2. This generic model correlates well to test data and incorporates both fuel cell stack and subsystem models. This feature allowed HEVT to predict the benefits of load following subsystem control, showing a 40% fuel economy improvement.
