Efficacy of an enzyme-linked immunosorbent assay for detection of urinary tract immunoglobulins for diagnosis of urinary tract infections

Results of the Uristat test (Shield Diagnostics Ltd.), a novel enzyme-linked immunosorbent assay (ELISA) for detection of urine antibodies to seven common bacterial pathogens, were compared with results of urine culture, urinalysis, and clinical history to determine the usefulness of Uristat in the diagnosis of urinary tract infections (UTIs). Midstream, catheterized, and indwelling catheter urine specimens sent to the laboratory for culture were included in the study. Quantitative cultures were performed on both 5% sheep blood agar and eosin-methylene blue agar. Uristat ELISAs were performed according to the manufacturer's instructions. By using a Bacillus subtilis bioassay technique, antibacterial activity was detected in the urine of 236 (22.2%) of 1,061 patients. Probable, possible, or asymptomatic UTIs were diagnosed for 258 (24.3%) of the 1,061 patients. Of those infections, 219 (84.9%) were caused by bacterial species whose antibodies were detectable by Uristat. Uristat's sensitivity and specificity were 76.7 and 56.0%, respectively. Uristat's predictive values of positive and negative results were 31.2 and 90.2%, respectively. Further development of the Uristat test is necessary before it can be of assistance in the diagnosis of UTIs.
Courting Difference: Issues of Interpretation and Comparison in the Study of Legal Ideologies

This article explores the connections between the interpretive and comparative dimensions of ideology by analyzing ethnographic data from an American town. The town is undergoing a rapid process of urbanization, and townspeople are absorbed in the analysis of the changes around them and their town's prospects as a community. The article compares interview data and courtroom observations in which local understandings are shown to be constituted in pervasive cultural distinctions: past and future, insiders and outsiders, harmony and conflict, gender, and various forms of family life shape local views of change and conflict. The conclusion relates an analysis of the symbolic terms in which these distinctions are expressed to general issues of the nature of ideologies and their truth claims.
A Framework to Quantify the Benefits of Network Functions Virtualization in Cellular Networks

Network functions virtualization (NFV) is an appealing vision that promises to dramatically reduce capital and operating expenses for cellular providers. However, existing efforts in this space leave open broad issues about how NFV deployments should be instantiated or how they should be provisioned. In this paper, we present an initial attempt at a framework that will help network operators systematically evaluate the potential benefits that different points in the NFV design space can offer.
Enhanced Color-to-Gray Conversion

Important visual details are lost when a color image is converted into a luminance image using GIMP, Adobe Photoshop, or other graphic tools (see Figure 1). An enhanced conversion method is presented that creates an optimized grayscale image with visual artifacts of the standard method reduced to a minimum. The run time of the algorithm is linear in the number of pixels and allows a very simple implementation compared to other color-to-gray solutions.
Teaching and learning about science practices: insights and challenges in professional development

The purpose of this study was to determine if science teachers showed a change in their ability to design and implement science lessons that integrate twenty-first century science practices as a result of their participation in a subject-specific professional development program. A qualitative design utilizing inductive analysis was used to investigate teachers’ ability to design inquiry-oriented lessons and implement them in the classroom. Eight science teachers participated in the study. Findings showed that teachers have benefited from their participation in the program and were able to plan and implement their inquiry-oriented lesson plans and implement them in the classroom. The analysis also showed that teachers were not able to demonstrate their ability in two dimensions of inquiry (asking scientifically oriented questions and designing and carrying out investigations). Finally, several suggestions were presented to modify the program’s training materials to focus more on these two dimensions of inquiry.
Model Based Design of pid controller for BLDC motor with implementation of embedded arduino mega controller

Brushless DC motors are the most widely used electrical drive in the industry. The development process of the drive is costly and time-consuming. However, various methods can be used to reduce the development time of the drive. This paper presents the Model-Based Design technique of Brushless DC Motor using MATLAB/Simulink with Arduino support block set. The model of BLDC motor is developed using black-box modeling approach; simulations are performed based on real-time data and processed using MATLAB System Identification tool box. The PID Controller is then designed and tuned within the simulations to attain the drive performance. For real-time application, the controller code is generated and uploaded into Arduino Mega embedded controller. The results obtained from simulation and experiment is discussed and compared. The performed works concludes that Model-based design technique can be applied in any control design application using low cost controller such as Arduino embedded controller.
Real-Time Tra c Measurements on MAGNET

Real-time traac measurements on MAGNET II, an integrated network test-bed based on Asynchronous Time Sharing, are reported. The quality of service is evaluated by monitoring the buuer occupancy distribution, the packet time delay distribution, the packet loss and the gap distribution of the consecutively lost packets. Our experiments show that both time delay and buuer occupancy distributions of multiplexed video sources display a marked bimodal behavior, which does not seem to depend on the buuer size. The reliance of the network designer on traac sources that do not exhibit substantial correlations can lead to implementations with serious congestion problems. For ATS based networks with diierent traac classes, the impact of a traac class on the performance of the other classes tends to be diminished when compared with one class based ATM networks.
-Catenin is required for endothelial-mesenchymal transformation during heart cushion development in the mouse

uring heart development endocardial cells within the atrio-ventricular (AV) region undergo TGF dependent epithelial-mesenchymal transformation (EMT) and invade the underlying cardiac jelly. This process gives rise to the endocardial cushions from which AV valves and part of the septum originate. In this paper we show that in mouse embryos and in AV explants TGF induction of endocardial EMT is strongly inhibited in mice deficient for endothelial -catenin, leading to a lack of heart cushion formation. Using a Wnt-signaling reporter mouse strain, we demonstrated in vivo and ex vivo that D EMT in heart cushion is accompanied by activation of -catenin/TCF/Lef transcriptional activity. In cultured endothelial cells, TGF 2 induces -smooth muscle actin ( SMA) expression. This process was strongly reduced in -catenin null cells, although TGF 2 induced smad phosphorylation was unchanged. These data demonstrate an involvement of -catenin/TCF/Lef transcriptional activity in heart cushion formation, and suggest an interaction between TGF and Wnt-signaling pathways in the induction of endothelialmesenchymal transformation.
1 Diagnosis and Differential Diagnosis of Parkinson ’ s Disease

Parkinsonian syndromes are a heterogeneous entity of movement disorders, which can be subdivided into idiopathic Parkinson’s disease, rare genetic forms of Parkinson’s disease as well as symptomatic and atypical parkinsonian syndromes. In addition, a number of other neurodegenerative disorders may show clinical signs of Parkinsonism. The etiology, histopathology, clinical manifestation and disease course varies significantly among these disorders. A correct and early differential diagnosis therefore is essential for proper prognostic estimation and consultancy of the patient as well as a prerequisite for inclusion in clinical studies. This chapter will summarize diagnostic criteria mainly focussing on the diagnosis of idiopathic Parkinson’s disease (iPD) and delineate specific factors to differentiate this disorder from other disease entities.
Esmolol Blunts the Cerebral Blood Flow Velocity Increase During Emergence from Anesthesia in Neurosurgical Patients

Cerebral hyperemia has been demonstrated during emergence from anesthesia in neurosurgical patients, but its mechanism is speculative. We performed this study to test the hypothesis that this could be attributed to sympathetic overactivity. Thirty neurosurgical patients were included in a prospective, randomized, double-blinded study comparing esmolol, a short-acting &bgr;-blocker, and a placebo. Esmolol (0.3 mg · kg−1 · min−1) was infused from the end of anesthesia to 15 min after extubation. Cerebral blood flow velocity (CBFV), mean arterial blood pressure, and heart rate were recorded before anesthesia, during anesthesia after surgery, at extubation, and 5–60 min after extubation. Cardiac output (COe) was estimated by using an esophageal Doppler from anesthesia to 60 min after extubation. CBFV, COe, and heart rate were significantly lower in the esmolol group. Mean arterial blood pressure was comparable between the groups. There was no correlation between CBFV and COe at any time point during the study. In conclusion, esmolol blunted the CBFV increase during emergence, confirming that sympathetic overactivity contributes to cerebral hyperemia during neurosurgical recovery.
On the Nature and Drivers of Coopetition

We advance an image of coopetition as a synthesis of the two alternative paradigms developed in the literature about the nature of the interdependences among firms; i.e., the competitive paradigm versus the cooperative paradigm. The competitive paradigm postulates divergent interest-based interdependences among firms, whereas the cooperative paradigm implicitly assumes that firms interact on the basis of a convergent - i.e., fully collaborative - interest structure. We suggest that coopetition arises when both the competitive and the cooperative features of inter-firm interdependence co-exist simultaneously, defining a game structure where firms interact on the basis of partially convergent interests. Additionally, we discuss the factors that contribute to give rise to this hybrid nature of inter-firm interdependences, proposing a set of environment-related and firm-related coopetition drivers. Our study provides relevant implication for research that we discuss in the final section of the paper.
A Bayesian model for two-way contingency tables with nonignorable nonresponse from small areas

Many surveys provide categorical data and there may be one or more missing categories. We describe a nonignorable nonresponse model for the analysis of two-way contingency tables from small areas. There are both item and unit nonresponse. One approach to analyze these data is to construct several tables corresponding to missing categories. We describe a hierarchical Bayesian model to analyze two-way categorical data from different areas. This allows a "borrowing of strength" of the data from larger areas to improve the reliability in the estimates of the model parameters corresponding to the small areas. Also we use a nonignorable nonresponse model with Bayesian uncertainty analysis by placing priors in nonidentifiable parameters instead of a sensitivity analysis for nonidentifiable parameters. We use the griddy Gibbs sampler to fit our models and compute DIC and BPP for model diagnostics. We illustrate our method using data from NHANES III data on thirteen states to obtain the finite population proportions.
Deuterium and Oxygen toward Feige 110: Results from the FUSE Mission

We present measurements of the column densities of interstellar D I and O I made with the Far Ultraviolet Spectroscopic Explorer (FUSE) and of H I made with the International Ultraviolet Explorer (IUE) toward the sdOB star Feige 110 [(l,b) = (74.°09, - 59.°07); d = 179 pc; z = -154 pc]. Our determination of the D I column density made use of curve-of-growth fitting and profile fitting analyses, while our O I column density determination used only curve-of-growth techniques. The H I column density was estimated by fitting the damping wings of the interstellar Lyα profile. We find log N(D ) = 15.47 ± 0.06, log N(O ) = 16.73 ± 0.10, and log N(H ) = 20.14 (all errors 2 σ). This implies D/H = (2.14 ± 0.82) × 10-5, D/O = × 10-2, and O/H = (3.89 ± 1.67) × 10-4. Taken with the FUSE results reported in companion papers and previous measurements of the local interstellar medium (LISM), this suggests the possibility of spatial variability in D/H for sight lines exceeding ∼100 pc. This result may constrain models which characterize the mixing timescales and length scales of material in the LISM.
A Low-Profile Stacked Dielectric Resonator Antenna With High-Gain and Wide Bandwidth

A wideband, low profile and high gain dielectric resonator antenna is investigated in this letter. The antenna consists of two dielectric layers with different permittivities and it is centrally fed by a rectangular slot. By placing the dielectric layer of low permittivity (2.2) below that of high permittivity (15), the antenna with low profile of 0. 1λ0 can obtain a 10-dB impedance bandwidth of ~ 40% and an average gain of ~ 9 dBi.
Effect of a Home Learning Program on Learning Disabled Children's Balance

Improving the balance of learning disabled children was investigated through the use of a structured gross motor home learning program. Fifteen boys ranging from 7 to 9 yr. (M = 7.9 yr., SD = 1.1) who were classified by the federal definition (2) as learning disabled were evaluated on static and dynamic balance components of the Six Category Gross Motor Survey (1). Ch~ldren scoring at least 1 SD below the mean for normal children of like chronological age on each test component were selected. Those children whose parents volunteered to conduct a 12-wk. home learning program were matched on their pretest balance scores and randomly assigned to Group 1. In Group 2 were those in a home program of fine motor and pre-academic tasks and in a control group those who were not in any home program. Each group also received a 12-wk. physical education program conducted at school by the same physical educator. The program for Group 1 included developmental static and dynamic balance tasks such as standing on one foot and walking lines/boards, etc. Group 2 included cutting, listening to records, and reading newspapers/magazines. Each group was instructed in the use of the materials prior to the initiation of the program. Specific directions for teaching, provisions for modeling and/or prompting responses, and equipment were included in a packet. Training was implemented by weekly follow-up telephone calls. At the end of a 12-wk. program (three times weekly for 30 min. a day) and a minimum of 30 home sessions (M = 33.1, SD = 2.7), each child was re-evaluated on static and dynamic balance. Using a Wilcoxon matched-pairs signed-ranks analysis and a Mann-Whitney U test (4). it was concluded that parents can significantly enhance (p < .05) the static and dynamic balance of their learning disabled children by implementing a structured gross-motor training program at home; see the data. This supplements the position of many authors who reported that balance of handicapped children can be improved through practice (3). It is important that parents can supplement a school's physical education program and provide support when there is little time or opportunity for an individualized program for children with special needs.
The cholesterolaemic effects of dietary fats in cholesteryl ester transfer protein transgenic mice

In order to investigate the role of cholesteryl ester transfer protein (CETP) in the cholesterolaemic response to dietary fats, we analysed plasma lipid profiles of CETP-transgenic and control C57BL/6 mice fed standard chow (AIN-93G; AIN), a low-fat diet, and diets high in butter (saturated fatty acids; SFA), high-oleic acid safflower oil (monounsaturated fatty acids; MUFA), and safflower oil (polyunsaturated fatty acids; PUFA) for 5 weeks. Each group contained four or five mice. There were significant diet and diet×genotype effects on plasma total cholesterol (TC; P = 0·035 and P = 0·008 respectively), liver TC (P < 0·001 and P = 0·002 respectively), and esterified cholesterol (EC; P = 0·002 and P = 0·001 respectively); diet effects on plasma triacylglycerol (P = 0·007), liver free cholesterol (P < 0·001), and body weight (P = 0·027); a genotype effect on body-weight gain (P = 0·014); and a diet×genotype effect on energy intake (P = 0·006). In transgenic mice the SFA diet caused significantly higher plasma TC than the PUFA diet (P < 0·05). In control mice MUFA and PUFA diets, but not the SFA diet, caused significantly higher plasma TC than the low-fat and AIN diets (P < 0·05). Transgenic mice fed PUFA had lower plasma TC (P = 0·040), while transgenic mice fed MUFA had lower LDL+VLDL-cholesterol (P = 0·013) than controls in the same dietary groups. Transgenic mice fed MUFA and PUFA diets also had significantly higher liver TC (P = 0·020 and P = 0·002 respectively) and EC (P = 0·040 and P = 0·036 respectively) than controls fed the same diets. In the present study we showed that: (1) CETP transgenic mice had a cholesterolaemic response to dietary fats similar to that in human subjects; (2) CETP transgenic mice fed PUFA showed significantly lower plasma TC, while those fed MUFA had lower LDL+VLDL-cholesterol than controls; (3) hepatic accumulation of cholesterol, possibly resulting from the combination of the enhanced cholesteryl ester transfer to apolipoprotein B-containing lipoproteins and increased hepatic uptake of cholesterol, may contribute to the cholesterol-lowering effect of MUFA and PUFA in CETP-transgenic mice; (4) CETP may play a role in appetite and/or energy regulation.
Visual surveillance and monitoring system using an omnidirectional video camera

This paper describes a visual surveillance and monitoring system which is based on omnidirectional imaging and view-dependent image generation from omnidirectional video streams. While conventional visual surveillance and monitoring systems usually consist of either a number of fixed regular cameras or a mechanically controlled camera, the proposed system has a single omnidirectional video camera using a hyperboloidal mirror. This approach has an advantage of less latency in looking around a large field of view. In a prototype system developed, the viewing direction is determined by viewers' head tracking, by using a mouse, or by moving object trading in the omnidirectional image.
The Schooling Experience of Adolescent Boys with AD/HD: An Australian Case Study

Abstract This study explored the experience of schooling of six adolescent boys diagnosed with AD/HD from the perspectives of the boys, their mothers and their teachers. The study utilised social constructionism as the theoretical orientation and the Dynamic Developmental Theory (DDT) of AD/HD as the explanatory framework. Utilising a multiple, instrumental case-study, data were collected by means of semi-structured individual and focus group interviews as well as a review of school reports across a two year period. Findings of the study suggest that taking medication as prescribed together with supporting the students to make and manage friendships, utilising classroom strategies that support learning, and providing an engaging classroom environment are important considerations to promote a positive schooling experience for adolescents with AD/HD.

Preparation and Characterization of 125I Labeled Bovine Serum Albumin

Bovine serum albumin is a model protein, which has been conventionally used as protein standard and in many areas of biochemistry, pharmacology and medicine. Radioiodination procedure for bovine serum albumin employing chloramine-T as an oxidant with slight modification was evaluated critically to establish the optimal conditions for the preparation of radiolabeled tracer (125I-BSA) with required specific activity without impairing the immune reactivity and biological activity. Optimized radioiodination procedure involving 10 µg of chloramine-T along with 20 µg of sodium metabisulphite with 60 seconds incubation at 2° yielded 125I-BSA with high integrity.
Freezing Injury in Onion Bulb Cells: II. Post-thawing Injury or Recovery.

Onion (Allium cepa L.) bulbs were subjected for 12 days to either a moderate freeze (-4 C) or a severe freeze (-11 C). They were then thawed slowly over ice. During 7 to 12 days following the thaw, the injury progressed with time in the severely frozen bulbs, but appeared completely repaired in the moderately frozen bulbs. This was shown by the following post-thawing changes.Infiltration of the intercellular spaces increased from 80 to 90% to 100% after the severe freeze, and decreased from 30 to 50% to zero after the moderate freeze. All of the cells were alive immediately after thawing whether the freeze was moderate or severe. Corresponding to the infiltration results 7 to 12 days later, many to most were dead following the severe freeze, all were alive following the moderate freeze.The conductivity of the effusate from pieces of bulb tissue increased after the severe freezing, and decreased after the moderate freezing. The concentration of K(+), total solutes, and sugars in the effusate paralleled the conductivity changes. Neither the pH of the effusate nor the permeability of the cells (as long as cells were living) to water was changed following either the severe or the moderate freezes. Some treatments of the thawed tissue following the severe freeze halted the progress of injury.The above results indicate that the semipermeable properties of the cell are uninjured but that the ion and sugar transport mechanism is damaged by freezing. Most likely the primary injury is to the active transport mechanism involved in their transport. It must be concluded that the final injury following freezing and thawing cannot be evaluated from the degree of infiltration or the conductivity of the effusate immediately after thawing, since injury may progress or recede following the thawing.
