Assessing the sensitivity of egg yolk antibody testing for detecting Salmonella enteritidis infections in laying hens (1997)

The identification of infected commercial poultry flocks has become a pivotal component of efforts to reduce the incidence of egg-associated transmission of Salmonella enteritidis to humans. To assess the sensitivity with which testing for specific antibodies in egg yolks can be applied to detect S. enteritidis infection in laying chickens, groups of hens were orally inoculated with either 10(3), 10(5), or 10(7) cfu of a phage type 13a strain of S. enteritidis. Eggs from these hens were collected for 4 wk after inoculation and yolk samples were tested for antibodies to S. enteritidis flagella by ELISA. All hens that were inoculated with 10(7) cfu of S. enteritidis were detected as infected by the egg yolk ELISA when eggs were tested individually, as were up to 66 and 35% of hens inoculated with 10(5) or 10(3) cfu, respectively. Even when yolks from infected hens were diluted 1:10 in yolk from uninfected hens, specific antibodies could still be found in eggs from 31% of hens given 10(7) cfu of S. enteritidis and 13% of hens given 10(3) cfu. These results demonstrate that egg yolk antibody testing can provide a highly sensitive indication of prior exposure to S. enteritidis, and should accordingly be useful for verifying the effectiveness of programs designed to reduce the incidence of S. enteritidis infection in poultry.
Proving the usefulness of a 3-port nonlinear vectorial network analyser through mixer measurements (2003)

A 3-port Nonlinear Vectorial Network Analyser (NVNA) is presented. This new measurement instrument allows designers for the first time to measure the full nonlinear 3-port behaviour for any arbitrary mixer. The usefulness of the 3-port NVNA is proven on amplitude and phase calibrated 3-port measurements of a microwave mixer.
Influence of native endophytic bacteria on the growth and bacterial crown rot tolerance of papaya ( <i>Carica papaya</i> ) (2019)

Abstract The native plant microbiome is composed of diverse communities that influence its overall health, with some species known to promote plant growth and pathogen resistance. Here, we show the antimicrobial and growth promoting activities of autoclaved culture metabolites (ACMs) from native endophytic bacteria (NEB) in a papaya cultivar that is tolerant to bacterial crown rot (BCR) caused by Erwinia mallotivora . Initially, bacterial colonization in recovering tissues of this cultivar was observed before onset of tissue regeneration or ‘regrowth’. We further isolated and characterized these bacteria and were able to identify two culturable stem NEB under genera Kosakonia (EBW), related to Enterobacter, and Sphingomonas (EBY). We also identified root NEB (BN, BS and BT) under genus Bacillus . Inhibition assays indicated that ACMs from these NEB promptly (18-30h) and efficiently inhibited (60-65%) E. mallotivora proliferation in vitro . Interestingly, when ACMs from BN and EBW were inoculated in surface-sterilized papaya seeds, germination was variably retarded (20-60% reduction) depending on plant genotype, but plant biomass accumulation was significantly stimulated, at around two-fold increase. Moreover, greenhouse experiments show that ACMs from all isolates, especially EBW, significantly reduced BCR incidence and severity in susceptible genotype, at around two-fold. In general, our observations of pathogen antagonism, plant growth promotion leading to disease reduction by ACMs of native endophytic bacteria suggested its contribution to increased fitness of papaya and tolerance against the (re)emerging BCR disease.
Tubercle disease (Xanthomonas beticola) and other gall-malformed diseases of sugar beet roots: a review (2016)

The sugar beet (Beta vulgaris) is an important plant in agriculture and sugar industry, and it is widely cultivated in European countries. Getting proper raw material of sugar beets (roots) is a problem for agriculture. Some disease symptoms observed on sugar beet roots are atypical tumor-like deformations. The causative agent of these deformations is known in the old literature as Xanthomonas beticola. The disease’s name in Poland is “tuberkuloza” and in the USA it refers to a description of a pocket disease—therefore we may consider those diseases to be the same. The clear description of X. beticola disease can be found in many phytopathological manuals printed in the past and nowadays. Symptoms of the disease were noted in Poland last year, and the preliminary data of the yield quality show that the quality of diseased roots is worse (less sugar content) than of healthy roots. For the proper disease diagnoses, the literature was searched and this searching lead us to conclusion that there is no simple way to recognize the causal organism in the field conditions, and we suppose that X. beticola does not exist.
Human rights (and wrongs) of DNA testing and evidence (2001)

Extract: There has been considerable media coverage and public discussion about DNA testing in the past few years. This is because of a number of high profile cases where DNA evidence has been utilised. It is also because DNA evidence is said to have revolutionised police investigative methods and is set to eclipse traditional forms of forensic evidence presented at trial.

Abstract 655: The next generation of targeted toxins: A novel deimmunized sarcin ribotoxin fused with an EphA2 Abdurin binder (2015)

Abstract Abdurins are a novel antibody-like scaffold derived from the engineering of a single CH2 domain (CH2D) of IgG. The prolonged serum half-life of Abdurins, the result of retained FcRn binding, is 10-20 times longer than the serum half-life of any other protein scaffold of comparable molecular weight. Here we present data on the isolation and characterization of high affinity ABDURIN binders to the cancer target EphA2. α-Sarcin is a small (17 kDa) fungal ribonuclease produced by Aspergillus giganteus. Sarcin functions by catalytically cleaving a single phosphodiester bond in the sarcin-ricin loop, a well-defined RNA motif within the rRNA scaffold of the large ribosomal subunit. This cleavage makes the ribosome unrecognizable to elongation factors and hence, blocks protein synthesis. We have deimmunized α-sarcin (Sarcin-DI) and made several variants lacking T cell epitopes while retaining cytotoxic activity. This novel Abdurin EphA2 binder fusion with Sarcin-DI creates a new generation of targeted toxins with a longer half-life, low immunogenicity and potent tumor cell killing. Citation Format: Kurt R.

Real-time rendering of woven clothes (2003)

Virtual environments containing humans moving and performing actions in real time are ubiquitous in computer graphics applications. Such characters are often clothed in woven fabrics. This paper presents a technique for visualizing woven clothes in real time, while optimizing the realistic appearance. The proposed approach supports rendering of complex weave patterns by adopting Weaving Information File (WIF), a standard from textile Computer Aided Design (CAD) for representing the grammar of weaving. We develop a realistic rendering scheme by combining the grammar representation obtained from the WIF with a procedural thread texture, a suitable cloth Bi-directional Reflectance Distribution Function (BRDF) and horizon maps. We employ the multi-texturing approach to meet the real time constraint. Thus our approach to visualizing woven clothes begins from weaving grammar specifications and converts them into textures that can be applied on clothes. We demonstrate the versatility of the proposed approach with examples.
Preparation of New Core [~(99)Tc~m(CO)_2(NO)]~(2+) and Its Derivatives [~(99)Tc~m(CO)_2(NO)-L](L=DTPA,EDTA,EHIDA) in Aqueous Solution (2009)

In order to develop a new method for the preparation of the [99Tcm(CO)2(NO)-L](L=DTPA,EDTA,EHIDA) complexes in aqueous solution,two different procedures were developed: one is formation of the metal-tricarbonyl-ligand complex and subsequent nitrosylation;another is nitrosylation of the metal-tricarbonyl precursor followed by reaction with the ligand.The optimal labeling conditions were studied.Results of TLC and HPLC indicate that the radiochemical yields derived from the two methods list above are all more than 90%.It's an easier new way to prepare [99Tcm(CO)2(NO)-L] complexes in aqueous solution with high efficiency.The newly developed [99Tcm(CO)2(NO)-L] complexes are stable at room temperature during 1 half-life of the isotope.At the same time,the lipophility and net charge of [99Tcm(CO)2(NO)-L] complexes are also changed comparing with that of corresponding [99Tcm(CO)3]+ core complexes.It opens a new field for designing radiopharmaceuticals.
An efficient implementation of RC4 cipher for encrypting multimedia files on mobile devices (2007)

Abstract. In this paper, we implement and evaluate an efficient RC4 stream cipher, called key-pooled RC4, to transfer securely multimedia files in the wireless mobile network. In key-pooled RC4, a 1MB-sized key stream pool, which consists of 2048 or 8192, or 32768 key stream frames, is created uniquely for each client device in the registration step. When a client requests a multimedia file, the server delivers the file after encrypting it using the sequence of key stream frames which are randomly selected from the corresponding key stream pool. Our experimental results show that the proposed scheme is more time efficient than the normal RC4. Moreover, the key-pooled RC4 scheme is more secure than normal RC4.
Recovery of Organic Products from Ionic Liquids Using Supercritical Carbon Dioxide (2000)

Ionic liquids (ILs) hold great potential as replacements for traditional volatile organic solvents and have been shown to be a viable medium for numerous types of reactions. This work investigates the feasibility of using supercritical carbon dioxide, another environmentally benign solvent, for the separation of organic solutes from an ionic liquid. Recovery rates of aromatic and aliphatic solutes from 1-n-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) are given. Supercritical fluid extraction is shown to be a viable separation technique with the additional benefits of environmental sustainability and pure product recovery.

Comparative Studies of Different Imputation Methods for Recovering Streamflow Observation (2015)

Faulty field sensors cause unreliability in the observed data that needed to calibrate and assess hydrology models. However, it is illogical to ignore abnormal or missing values if there are limited data available. This study addressed this problem by applying data imputation to replace incorrect values and recover missing streamflow information in the dataset of the Samho gauging station at Taehwa River (TR), Korea from 2004 to 2006. Soil and Water Assessment Tool (SWAT) and two machine learning techniques, Artificial Neural Network (ANN) and Self Organizing Map (SOM), were employed to estimate streamflow using reasonable flow datasets of Samho station from 2004 to 2009. The machine learning models were generally better at capturing high flows, while SWAT was better at simulating low flows.
Comparison of subcutaneous and intramuscular ketamine-medetomidine with and without reversal by atipamezole in Dutch belted rabbits (Oryctolagus cuniculus). (2007)

Forty male Dutch belted rabbits (Oryctolagus cuniculus) enrolled in a minimally invasive pharmacokinetics study were used to compare the efficacy of an anesthetic combination delivered through 2 injection routes. Rabbits were randomly assigned to 4 groups (n = 10/group) to determine the sedative and physiologic effects of ketamine (25 mg/kg)-medetomidine (0.5 mg/kg) given either intramuscularly (IM) or subcutaneously (SC). Palpebral, pedal, ear pinch, and righting reflexes, as well as cardiopulmonary parameters (heart rate, respiratory rate, and arterial blood oxyhemoglobin saturation), were recorded every 5 min. In addition, the reversal effects of an intravenous dose of atipamezole (1 mg/kg), an alpha 2 adrenoreceptor antagonist, were assessed by comparing the return of the righting reflex in rabbits given the reversal agent with those that recovered spontaneously. Compared with the IM route, SC ketamine-medetomidine effectively induced chemical restraint with less than a 2-min difference in onset of anesthesia and markedly less resistance (for example, fl inching, kicking, and so forth) during the injection. In all groups, the anesthetic regimen, regardless of the route of administration, provided an adequate level of anesthesia. Reversal with atipamezole improved arterial hemoglobin oxygen saturation for both the SC and IM groups; however, an enhanced rate of recovery from anesthesia was clinically apparent only for animals given the combination by the IM route.

On-Chip Hybridization Kinetics for Optimization of Gene Expression Experiments (2008)

DNA microarray technology is a powerful tool for getting an overview of gene expression in biological samples. Although the successful use of microarray-based expression analysis was demonstrated in a number of applications, the main problem with this approach is the fact that expression levels deduced from hybridization experiments do not necessarily correlate with RNA concentrations. Moreover oligonucleotide probes corresponding to the same gene can give different hybridization signals. Apart from cross-hybridizations and differential splicing, this could be due to secondary structures of probes or targets. In addition, for low-copy genes, hybridization equilibrium may be reached after hybridization times much longer than the one commonly used (overnight, i.e., 15 h). Thus, hybridization signals could depend on kinetic properties of the probe, which may vary between different oligonucleotide probes immobilized on the same microarray. To validate this hypothesis, on-chip hybridization kinetics and duplex thermostability analysis were performed using oligonucleotide microarrays containing 50-mer probes corresponding to 10 mouse genes. We demonstrate that differences in hybridization kinetics between the probes exist and can influence the interpretation of expression data. In addition, we show that using on-chip hybridization kinetics, quantification of targets is feasible using calibration curves.
Detection of moving objects in railway using vision (2004)

In this paper, a new strategy to detect motion object in railway is presented, using vision and principal components analysis (PCA). For this purpose, a set of images of the railway static environment is first captured to obtain the transformation matrix that used in PCA. By means of this matrix, the successive images are projected in the transformation space and recovered. The motion detection is performed, evaluating the Euclidean distance between the original and recovered images. The image regions whose Euclidean distance are greater than a threshold, are considered like belonging to motion objects. The new of our system is the utilization of a method to obtain an adaptive threshold that allows to classify, within an image, zones without motion (background) and motion objects. A system with dynamic adjustment of this threshold is proposed, which it compensates to a great extent, illumination and others environmental conditions variations founded in outdoor spaces. Anyway, to show the validity and robustness of this method, the system has been implemented practically.
Investigation and prevention of clogging during electrospinning of zein solution (2010)

Abstract Electrospinning is the only known technique for fabrication of long non‐woven ultrafine‐fibers. However, a number of limitations, including low productivity and clogging of a spinneret, substantially paralyses industrial scale up of the process. Clogging is indeed an unavoidable phenomenon during electrospinning of biopolymers and the exact reason for clogging is still unclear. The aim of the present study was thus to investigate the clogging phenomenon via the study of a solution of zein/ethanol, which was used as a model biopolymer system. The gel‐like substance causing clogging at the spinneret was collected and its infrared spectrum and rheological properties were determined via Fourier transform infrared (FTIR) spectrophotometry and rheometry, respectively. The results indicated that clogging was due to solvent evaporation, which led to formation of a highly viscous semi‐solid at the spinneret. Moreover, the results also revealed that the applied voltage and polymer concentration were the key parameters affecting clogging. A means to help avoid clogging and hence an ability to continuously perform electrospinning was also proposed and tested. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Generating the Super-resolution Image for the Video from the In-vehicle Data Recorder (2019)

The goal of this research is to generate high-resolution images in ROI by the low-resolution video from the In-Vehicle Device Recorder (IVDR). First, we decide the search region and trajectory of the feature through the construction of the camera model and analysis the imaging geometry and characteristics in the moving camera. Next, we consider the image perturbation and blurring caused by camera movement and try to reduce the impact on image quality. Using the projection geometry can track the trajectory of the feature points movement in the video. An accurately point position estimation in different resolutions requirement is made by the phenomenon that the image will be enlarged over time. We use the patching method to create the high-resolution image in ROI. The proposed rebuilding method for super-resolution imaging is based on motion characteristics of spatial domain features. This method can avoid the problem that generates ring noise using the traditional frequency method. It also has the advantage of simple computing.
Optimization of Mutual Information for (2000)

We propose a new method for the intermodal reg- istration of images using a criterion known as mutual informa- tion. Our main contribution is an optimizer that we specifically de- signed for this criterion. We show that this new optimizer is well adapted to a multiresolution approach because it typically con- verges in fewer criterion evaluations than other optimizers. We have built a multiresolution image pyramid, along with an interpo- lation process, an optimizer, and the criterion itself, around the uni- fying concept of spline-processing. This ensures coherence in the way we model data and yields good performance. We have tested our approach in a variety of experimental conditions and report excellent results. We claim an accuracy of about a hundredth of a pixel under ideal conditions. We are also robust since the accuracy is still about a tenth of a pixel under very noisy conditions. In addi- tion, a blind evaluation of our results compares very favorably to the work of several other researchers.
Kinetic modeling of rapid enzymatic hydrolysis of crystalline cellulose after pretreatment by NMMO (2011)

Pretreatment of cellulose with an industrial cellulosic solvent, N-methylmorpholine-N-oxide, showed promising results in increasing the rate of subsequent enzymatic hydrolysis. Cotton linter was used as high crystalline cellulose. After the pretreatment, the cellulose was almost completely hydrolyzed in less than 12 h, using low enzyme loading (15 FPU/g cellulose). The pretreatment significantly decreased the total crystallinity of cellulose from 7.1 to 3.3, and drastically increased the enzyme adsorption capacity of cellulose by approximately 42 times. A semi-mechanistic model was used to describe the relationship between the cellulose concentration and the enzyme loading. In this model, two reactions for heterogeneous reaction of cellulose to glucose and cellobiose, and a homogenous reaction for cellobiose conversion to glucose was incorporated. The Langmuir model was applied to model the adsorption of cellulase onto the treated cellulose. The competitive inhibition was also considered for the effects of sugar inhibition on the rate of enzymatic hydrolysis. The kinetic parameters of the model were estimated by experimental results and evaluated.
Liposomal dosage form development--some practical considerations. (1983)

Liposomes have attracted much attention in recent years as a potential drug carrier for parenteral use. Successful application of the liposomal drug delivery concept has been demonstrated in the treatment of experimental leishmaniasis with antimonial drugs in animal models. Development of this laboratory research concept into a viable product for clinical use is anticipated to pose numerous technological problems. Various approaches available to resolve some of the problems and to devise suitable formulations are considered. Finally, some of the experiences with the encapsulation of sodium stibogluconate (Pentostam) are briefly described.
