Antigen--antibody reaction investiaged with use of a chemically modified electrode. (1980)

The antigen-antibody reaction of human choriogenadotropin has been potentiometrically investigated by use of a cyanogen bromide-treated electrode coated with the corresponding anti-serum. The potential of the modified electrode shifts in the positive direction upon contact with a solution of choriogonadotropin. The rate of the reaction at the interface between the electrode and the solution is estimated from the potentiometric measurement to be of the order of 10(4) mol-1 s-1 in diethyl barbiturate buffer, depending to some extent on the rotation speed of the stirrer. The change in potential is almost proportional to choriogonadotropin concentration. It is also pH dependent, the maximum response being at pH 8.7. The technique, applied to samples of human urine, has shown a specific response to choriogonadotropin.

Cell envelope alterations in antibiotic-sensitive and-resistant strains of Neisseria gonorrhoeae (1978)

The cell envelopes of antibiotic-resistant and -sensitive isogenic strains of Neisseria gonorrhoeae were analyzed to determine whether acquisition of genetic loci for altered antibiotic sensitivity was accompanied by alterations in cell envelope composition. No differences in the composition of phospholipids and lipopolysaccharides were noted. Acquisition of mtr-2, which results in low-level, nonspecific increased resistance to multiple antibiotics, dyes, and detergents, was accompanied by a sevenfold increase in the amount of a minor, 52,000-molecular-weight outer membrane protein and a 32% increase in the extent of peptidoglycan cross-linking. Subsequent addition of the nonspecific hypersensitivity loci env-1 or env-2 to a strain carrying mtr-2 resulted in reversal of the phenotypic resistance determined by mtr-2 and marked reduction in both the amount of the 52,000-molecular-weight outer membrane protein and the extent of peptidoglycan cross-linking. Introduction of penB2, which results in a fourfold increase in resistance to penicillin and tetracycline, was accompanied by the disappearance of the principal outer membrane protein of the wild-type strain (molecular weight, 36,900) and the appearance of a new species of the principal outer membrane protein (molecular weight, 39,400) in the transformant.
BCL-X expression in multiple myeloma: possible indicator of chemoresistance. (1990)

Because murine myeloma plasma cells and normal human lymph node plasma cells express BCL-X, we evaluated BCL-X expression in malignant human plasma cells. BCL-X expression was detected in several human myeloma cell lines, as well as in CD38-sorted bone marrow cells obtained from some patients. Only the antiapoptotic long form of BCL-X (BCL-X-L), was detected. Because BCL-X-L expression can protect tumor cells from apoptotic death induced by chemotherapeutic agents, we tested the clinical relevance of expression in 55 archival bone marrow biopsies. The biopsies were stained by immunohistochemistry, and BCL-X expression was correlated with the subsequent response to treatment. BCL-X expression in malignant plasma cells strongly correlated with decreased response rates in patient groups treated with either melphalan and prednisone or vincristine, Adriamycin, and dexamethasone. Response rates were 83-87% in non-BCL-X-expressing cases and 20-31% in BCL-X-expressing cases. In addition, BCL-X expression was more frequent in specimens taken from patients at relapse (77%), when compared to those at initial diagnosis (29%). Further support for the association of drug resistance with BCL-X-L expression came from studies of the 8226 dox-40 cell line. This line, which expresses p-glycoprotein and serves as a model of multidrug resistance in multiple myeloma cells, demonstrated an up-regulated expression of BCL-X-L, which was relatively specific, in that BCL-2 or BAX expression was not altered. In addition, dox-40 cells demonstrated a generalized resistance to apoptosis that was induced by several different agents. These results indicate that malignant plasma cells can express BCL-X-L and that such expression may be a marker of chemoresistant disease.
Multisite Evaluation of a New Diabetes Self-Test for Glucose and Glycated Protein (Fructosamine) (2000)

The Duet Glucose Control System is accurate for both measuring glucose and GlucoProtein (fructosamine) using a fingerstick blood sample. This new testing system has the potential to provide useful information to both healthcare specialists in their office and also to patients at home to help them achieve better long-term glucose control and avoid the potential acute and chronic complications of diabetes.
Density estimation by stochastic complexity (1992)

The results by P. Hall and E.J. Hannan (1988) on optimization of histogram density estimators with equal bin widths by minimization of the stochastic complexity are extended and sharpened in two separate ways. As the first contribution, two generalized histogram estimators are constructed. The first has unequal bin widths which, together with the number of the bins, are determined by minimization of the stochastic complexity using dynamic programming. The other estimator consists of a mixture of equal bin width estimators, each of which is defined by the associated stochastic complexity. As the main contribution in the present work, two theorems are proved, which together extend the universal coding theorems to a large class of data generating densities. The first gives an asymptotic upper bound for the code redundancy in the order of magnitude, achieved with a special predictive type of histogram estimator, which sharpens a related bound. The second theorem states that this bound cannot be improved upon by any code whatsoever.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Tunable Thermo‐Responsive Poly(<i>N</i>‐vinylcaprolactam) Cellulose Nanofibers: Synthesis, Characterization, and Fabrication (2012)

Abstract Temperature‐responsive PVCL homopolymers and functional PVCL polymers containing carboxylic acids are prepared in organic and aqueous solutions. PVCL bulk polymers are characterized using 1 H NMR, photometry, ATR‐FTIR, and thermal analysis. A finite phase transition at 37–40 °C occurs in aqueous solutions of PVCL and PVCL‐COOH. PVCL and PVCL‐COOH polymers are electrospun into fibers ranging from 100 to 2300 nm in diameter. PVCL/cellulose bi‐component films are obtained by electrospinning of CA and PVCL followed by alkaline hydrolysis. These tunable thermo‐responsive PVCL/cellulose nanofibers have potential applications in developing affinity membranes. magnified image
Utility of RNA Sequencing for Analysis of Maize Reproductive Transcriptomes (2011)

Transcriptome sequencing is a powerful method for studying global expression patterns in large, complex genomes. Evaluation of sequence-based expression profiles during reproductive development would provide functional annotation to genes underlying agronomic traits. We generated transcriptome profiles for 12 diverse maize (Zea mays L.) reproductive tissues representing male, female, developing seed, and leaf tissues using high throughput transcriptome sequencing. Overall, ∼80% of annotated genes were expressed. Comparative analysis between sequence and hybridization-based methods demonstrated the utility of ribonucleic acid sequencing (RNA-seq) for expression determination and differentiation of paralagous genes (∼85% of maize genes). Analysis of 4975 gene families across reproductive tissues revealed expression divergence is proportional to family size. In all pairwise comparisons between tissues, 7 (pre- vs. postemergence cobs) to 48% (pollen vs. ovule) of genes were differentially expressed. Genes with expression restricted to a single tissue within this study were identified with the highest numbers observed in leaves, endosperm, and pollen. Coexpression network analysis identified 17 gene modules with complex and shared expression patterns containing many previously described maize genes. The data and analyses in this study provide valuable tools through improved gene annotation, gene family characterization, and a core set of candidate genes to further characterize maize reproductive development and improve grain yield potential.
Risk-Sensitive Sequential Action Control with Multi-Modal Human Trajectory Forecasting for Safe Crowd-Robot Interaction (2020)

This paper presents a novel online framework for safe crowd-robot interaction based on risk-sensitive stochastic optimal control, wherein the risk is modeled by the entropic risk measure. The sampling-based model predictive control relies on mode insertion gradient optimization for this risk measure as well as Trajectron++, a state-of-the-art generative model that produces multimodal probabilistic trajectory forecasts for multiple interacting agents. Our modular approach decouples the crowd-robot interaction into learning-based prediction and model-based control, which is advantageous compared to end-to-end policy learning methods in that it allows the robot's desired behavior to be specified at run time. In particular, we show that the robot exhibits diverse interaction behavior by varying the risk sensitivity parameter. A simulation study and a real-world experiment show that the proposed online framework can accomplish safe and efficient navigation while avoiding collisions with more than 50 humans in the scene.
Comparison of the antimicrobial efficacy of positive pressure and negative pressure irrigation technioues using chlorhexidine on entrococcus faecalis: An in-vitro study (2012)

The aim of this in vitro study was to determine whether irrigation with negative pressure was more etfective than traditional positive pressure in eradicating Enterococcus faecars using chlorhexidine.
Synthesis of Seven-Membered Ring Glycals via <i>endo</i>-Selective Alkynol Cycloisomerization (2004)

[reaction: see text] Alkynyldiols 1 undergo cycloisomerization to the corresponding seven-membered cyclic enol ethers 2 under tungsten carbonyl catalysis. This novel transformation proceeds with good yields and virtually complete regioselectivity for all diastereomers of 1, favoring the product 2 resulting from endo-mode cyclization. The unexpected regioselectivity may be dependent on the presence of the dioxolane structure tethering the terminal alkyne and diol functional groups.
Angular Deviation and Its Effect on Hud-Equipped Aircraft Weapons Sighting Accuracy. (1982)

At present, all forward windscreens (or canopies) installed on Hud-equipped aircraft are measured to determine their angular deviation, or induced aiming error. Standards have been set to accept only those transparencies which cause little aiming error, and at least one aircraft HUD fire control computer is provided with a means to compensate for the remaining error. This report is a summary of several of the multitudinous methods used to measure angular deviation for most HUD-equipped aircraft, with an explanation of the comparative accuracy of each method when applied to weapons aiming at operational sighting ranges. The advantages and disadvantages of each quality control system are discussed, and an attempt is made to reconcile the values of each system for sighting accuracy comparisons. A recommendation is made for a standardized method of measurement which is relatively error free, and best relates to operational use of the aircraft. (Author)
Energetic yields in apatitic calcium phosphate compression: influence of the Ca/P molar ratio (2003)

Abstract The chemical nature of tricalcium phosphate used as compression excipient is not well defined. It can vary between β‐tricalcium phosphate (Ca/P molar ratio = 1.50) and hydroxyapatite (Ca/P molar ratio = 1.67). The present study deals with the compression properties of calcium phosphates with different Ca/P molar ratios (1.50, 1.63 and 1.67) and two trading excipients elaborated by different manufacturing processes: TRI‐TAB® (granulated powder) and TRI‐CAFOS S® (spray‐dried powder). The compression properties are analyzed in terms of energetic compression yields deduced from the compression and rupture cycles. The results show that the proportions of friction and elasticity during apatitic calcium phosphate compression are the same, whatever the chemical nature and the manufacturing process of the material. The only property that differs greatly is the conversion of the energy into cohesion. In comparison with trading excipients, the synthesized apatitic calcium phosphate materials exhibit higher cohesion properties: the product with a Ca/P molar ratio of 1.63 is the most cohesive, the apatitic tricalcium phosphate converts to a smaller extent the compression energy into cohesion, whereas hydroxyapatite displays a similar compression ability as TRI‐TAB and TRI‐CAFOS S. This study shows the importance of the chemical nature on the compression properties of apatitic calcium phosphates, and the need to rationalize the physical grade as well as the chemistry of the commercialized materials. The elaboration process does not seem to influence the efficiency of the cohesion acquisition, but affects the flowability. © 2003 Society of Chemical Industry
Chemical Instability of Metal‐Deficient Hexagonal Ferrites with W Structure (1977)

The hexagonal ferrite W=BaFe 2+ 2 Fe 3+ 16 O 27 , which is in equilibrium with oxygen under 0.015 atm at 1350 ° C, is oxidized in the range 250 ° to 1100 ° C in the same atmosphere to BaFe 3+ 16+2x Fe 2 2‐3x > x O 27 with 2–3 x <0.03. The metal‐deficient W structure is chemically unstable and decomposes after longer annealing at the same temperature. This difference in oxidation and decomposition rate is attributed to a difference in the diffusion rate of barium and iron ions.
La necesaria mediación filosófica de la fe y la teología según Karl Rahner (2005)

Este artículo reconstruye los argumentos filosóficos con los cuales Karl Rahner intenta justificar racionalmente la posibilidad de la fe en una autocomunicación definitiva del Dios Trino en el acontecimiento de Cristo. La necesidad de una demostración filosófica de la posibilidad e inteligibilidad de una revelación definitiva de Dios en la historia humana resulta de la negación de tal revelación (Lessing, Hick) y de la exigencia intrínseca de una automediación de la fe misma en el horizonte de la razón.
The Design and Modelling of Automated Broadband Slide-Screw Tuners (1987)

This paper reviews the most recent automated tuning techniques and comments on their respective advantages. The development of a simple model, capable of predicting the response of a slide-screw tuner from 45 MHz to 18 GHz, is described and compared with measurements of an existing tuner. The parameters affecting slide-screw tuner performance are identified with particular attention being paid to the slug. A tuning slug design is presented achieving optimum tuner performance over the 2 to 18 GHz frequency range.
High yielding strains and varieties of corn for Iowa (1929)

This publication is a report of the Iowa Corn Yield Test, the primary object of which is to locate the strains and varieties which will produce the largest yields of dry shelled corn in the different sections and districts of the state. The Farm Crops Section of the Iowa Agricultural Experiment Station has cooperated with the Iowa Corn and Small Grain Growers’ Association from the time the work was first undertaken in 1920. Since 1922 this cooperation has been shared by the Office of Cereal Crops and Diseases of the United States Department of Agriculture which at that time assigned a scientific assistant to the work.\nThru the agricultural press and the annual reports of the association, yearly results of the yield comparisons have been given the public. But inasmuch as the average of accumulated tests is of especial significance in. a comparative study of varieties and strains, it is deemed advisable herewith to report certain results not previously available.
New data on the sorption properties of ?1-acid glycoprotein chiral stationary phase (1999)

A binding study on α1-acid glycoprotein (AGP), a widely used chiral stationary phase in drug analysis, has been performed. Being a selectivity decisive factor in enantiomer separation, the adsorption of the organic modifiers, as the regularly used acetonitrile (AcCN) and also of dioxane, was determined from phosphate buffer eluents (pH 7.2 and 4.0) in the concentration range of 0.57–3.81 M and 0.11–1.9 M, respectively. The adsorbed amount was determined by gas chromatography. At lower modifier concentrations no significant difference was found in the binding extent of AcCN and dioxane. At higher, characteristic concentrations of the organic additives, a saturation was obtained at both pH values; furthermore, at pH 4.0 it was followed by a definite rise in the modifier adsorption. This particular behaviour may indicate the exposure of new binding sites on AGP surface, as a result of changes in the protein structure, which was confirmed by CD-spectroscopic measurements. The pH dependence of binding in equimolar concentration (1.9 M) has shown the priority of dioxane at pH 4.0, while the adsorption of AcCN dominated at higher pH, indicating the different character of the two solvents. The increased hydrogen bond formation should cause the preferred adsorption of dioxane at pH 4.0. Chirality 11:212–217, 1999. © 1999 Wiley-Liss, Inc.
Comparison of serum CEA, PHI, and TPA as tumor markers in breast cancer patients. (1987)

The purpose of this study was to evaluate the clinical significance of different serum tumor markers in patients with breast cancer who developed recurrent disease. Determined were tissue polypeptide antigen (TPA), carcinoembryonic antigens (CEA), and phosphohexose isomerase (PHI). Serum samples of 411 breast cancer patients with either locoregional or metastatic recurrence were analyzed. Positive rates of all three markers depended on the clinical stage of the disease, with highest rates of elevated titers in advanced disease. In comparison, CEA and TPA are more sensitive markers than PHI. According to the site of recurrence, CEA exhibited the highest rate of elevated titers in patients with bone metastases and PHI in patients with visceral metastases. Using PHI in combination with CEA, sensitivity (ie, at least one marker is elevated) was increased by 6-20% compared to the results obtained with single marker analysis. However, for easier interpretation of the tumor marker results in clinical practice, it may be helpful to employ a product value of CEA and PHI.
<title>Line-scan system for all-round inspection of objects</title> (1997)

Sensor choice is critical in all object inspection imaging systems and the suitability of different types of sensor must be thoroughly assessed before a decision is made. Despite its wide use, a television type camera may not represent the best choice for certain object inspection applications. Specifically, when inspection of an object that has a degree of cylindrical symmetry is required, a line-scan camera is a viable alternative to the television type and, in general, any matrix camera, offering a number of unique advantages. By applying rotational motion to the object of interest and using a line-scan device, an 360 degree(s) view of the object is obtained. The cylindrical surface of the object is effectively unfolded into a planar 2D one, allowing for the efficient inspection of the entire surface of the object from a single, continuous image. To allow accurate object space co-ordinate measurement, a line-scan camera calibration technique has been developed, catering for both interior and exterior parameter calibration. The former accounts for the lens effective focal length, the pierce-pixel value and the timing of the line-scan camera, while the latter yields the relative position and orientation of the camera with respect to a reference object space co-ordinate system.
Cationic and Nonionic Starch Graft Polymers for Filler Retention (1975)

Abstract Graft co‐ and terpolymers were prepared by free radical polymerizations of vinyl monomers onto ω‐irradiated starch by a prototype commercial process. Products with graft contents of up to 46%, by weight, were obtained by grafting acrylamide and quaternary amine‐containing esters of methacrylic acid to starch. The graft polymers were evaluated on a pilot fourdrinier paper machine as filler retention aids and compared with several commercial flocculants. Drainage rate increased markedly with one of the starch graft terpolymers that was cationic. Since the number of starch graft polymers prepared was limited, the results reported, although excellent, are not necessarily optimal. Further studies are needed to establish the relationships of graft content and terpolymer compositions to retention and drainage.
Structure of menisporphine: A new type of isoquinoline alkaloid. (1982)

The structure of an unknown yellow base from Menisperum dauricum DC. (Menispermaceae) was determined to be 5, 6, 9-trimethoxy-7H-dibenzo [de, h] quinolin-7-one (1) by spectral data and total synthesis. It was named menisporphine and the skeletal name"oxoisoaporphine"was proposed for this new type of alkaloid. The biosynthesis route of oxoisoaporphine-type alkaloids in plants is suggested.
Inactivation of various proteinase inhibitors and the complement system in human plasma by the 56-kilodalton proteinase from Serratia marcescens (1989)

The interaction of the 56-kilodalton (kDa) proteinase from Serratia marcescens with human plasma activated C1 (C1) inhibitor, alpha 2-antiplasmin, and antithrombin III was investigated. The 56-kDa proteinase was not affected by these inhibitors; on the contrary, all the inhibitors were inactivated by the 56-kDa proteinase within 2 to 6 h. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis indicated that all three inhibitors showed decreases in molecular weight of approximately 8,000 to 10,000 as a result of proteolytic cleavage by the 56-kDa proteinase. The 56-kDa proteinase also inactivated serum complement within 2 to 6 h. The loss of inhibitory activity caused by the 56-kDa proteinase, together with the effects of endogenous serine proteinases, may facilitate tissue destruction and inflammation.
Training of familiar face recognition and visual scan paths for faces in a child with congenital prosopagnosia (2008)

In the current report we describe a successful training study aimed at improving recognition of a set of familiar face photographs in K., a 4-year-old girl with congenital prosopagnosia (CP). A detailed assessment of K.'s face-processing skills showed a deficit in structural encoding, most pronounced in the processing of facial features within the face. In addition, eye movement recordings revealed that K.'s scan paths for faces were characterized by a large percentage of fixations directed to areas outside the internal core features (i.e., eyes, nose, and mouth), in particular by poor attendance to the eye region. Following multiple baseline assessments, training focused on teaching K. to reliably recognize a set of familiar face photographs by directing visual attention to specific characteristics of the internal features of each face. The training significantly improved K.'s ability to recognize the target faces, with her performance being flawless immediately after training as well as at a follow-up assessment 1 month later. In addition, eye movement recordings following training showed a significant change in K.'s scan paths, with a significant increase in the percentage of fixations directed to the internal features, particularly the eye region. Encouragingly, not only was the change in scan paths observed for the set of familiar trained faces, but it generalized to a set of faces that was not presented during training. In addition to documenting significant training effects, our study raises the intriguing question of whether abnormal scan paths for faces may be a common factor underlying face recognition impairments in childhood CP, an issue that has not been explored so far.
