Understanding Collaboration Between Social Workers and Physicians

Abstract This article builds on prior analyses of data collected from a qualitative study of 50 pairs of social worker-physician collaborators in. This article presents the elements of a typology of collaborators from both professions developed from those analyses. The typology was also applied to the entire sample and each respondent characterized according to type (traditional, transitional or transformational). Further analysis was done to evaluate the relationships between type and collaborative perspectives. The sample was primarily transitional (56%-58%) and there were more traditional social workers (22%) and transformational doctors (24%) than anticipated. Social workers, as a group, were much less satisfied with the doctors than the doctors were with them although both groups of traditional respondents were the most dissatisfied. Both groups were least transformational in relation to control over decision making.
The network nullspace property for compressed sensing over networks

We study compressed sensing of graph signals defined over complex networks. In particular, we propose and analyze a convex optimization method for recovering smooth graph signals from a small number of samples. Assuming the true underlying graph signal to be constant over well connected subset of nodes (clusters), we derive a sufficient condition on the sampling set and network structure such that the proposed convex method is accurate. This condition, which we coin the network nullspace property, characterizes which nodes of the graph should be sampled in order to retain the full information about the underlying graph signal.
Differential expression of interleukin‐17 family cytokines in intact and complicated human atherosclerotic plaques

In addition to the classical TH1 and TH2 cytokines, members of the recently identified IL‐17 cytokine family play an important role in regulating cellular and humoral immune responses. At present nothing is known about the role of these cytokines in atherosclerosis. Expression of IL‐17A, ‐E and ‐F was investigated in atherosclerotic tissue by rtPCR and immunohistochemistry. IL‐17E and its receptor were further studied in cultured smooth muscle cells and endothelial cells, using rtPCR and western blot. rtPCR showed that IL‐17A, ‐E and ‐F were expressed in the majority of plaques under investigation. IL‐17A/F was expressed by mast cells in all stages of plaque development. IL‐17A/F+ neutrophils were always observed in complicated plaques, but hardly in intact lesions. IL‐17A/F+ Tcells (‘TH17’) were never observed. IL‐17E was expressed by smooth muscle cells and endothelial cells in both normal and atherosclerotic arteries, and in advanced plaques also extensively by mature B cells. Cultured smooth muscle cells and endothelial cells were found to express both IL‐17E and its functional receptor (IL‐17RB). The constitutive expression of IL‐17E by resident plaque cells, and the additional presence of IL‐17E+ B cells and IL‐17A/F+ neutrophils in advanced and complicated plaques indicates a complex contribution of IL‐17 family cytokines in human atherosclerosis, depending on the stage and activity of the disease.

Determination of the repose angle of stuff in rotary kiln based on imaging processing

The repose angle of materials in rotary kiln is an important parameter to describe stuff's motion which reflects the quality of stuff sinter indirectly. In this paper, a novel method, using digital image processing and linear fitting, is devoted to measure the repose angle. The whole process includes: images segmentation using FCM, Morphology operation to extract the stuff region, edge scanning and calculation of the repose angle with linear least square regression. The experiment carried out based on image captured from an alumina rotary kiln video. The result demonstrates its effectiveness to recognize the value and the variation trend of repose angle. It provides reliable and direct data to real-time detect stuff motion and can be utilized to judge the stuff quality, which is significant for operating optimization and automatic control of rotary kiln.
Navigated Diffusion Imaging of Normal and Ischemic Human Brain

The principal barrier to clinical application of diffusion‐weighted MR imaging is the severe image degradation caused by patient motion. One way to compensate for motion effects is the use of a “navigator echo” phase correction scheme. In this work, a modification of this technique is introduced, in which the phase correction step is performed in the frequency domain (i.e., after the readout Fourier transform). This significantly improves the robustness of the navigator echo approach and, when combined with cardiac gating, allows diagnostic quality diffusion‐weighted images of the brain to be routinely obtained on standard clinical scanner hardware. The technique was evaluated in phantom studies and in 23 humans (3 normal volunteers and 20 patients). Diffusion anisotropy and apparent diffusion coefficient maps were generated from the image data and showed decreased apparent diffusion in acute stroke lesions and, in several cases, increased apparent diffusion in chronic stroke lesions.
Diagnostic value of thyroglobulin assay in cervical lymph node fine-needle aspirations for metastatic differentiated thyroid cancer

Purpose of review Differentiated thyroid cancers (DTCs) have generally an indolent behavior. However, in a minority of these patients cervical metastasis at diagnosis or recurrence during follow-up may occur. Then, in suspicious neck lymph nodes fine-needle aspiration (FNA) is warranted. Thyroglobulin measurement in needle washout fluids (FNA-Tg) since its first description has been reported to increase the diagnostic accuracy of cytology in neck lymph nodes suspicious for metastatic DTC. Recent findings Recent literature suggests that FNA-Tg can substitute conventional cytology and, in turn, simplifies clinical management of DTC patients. However, because of the large difference between these clinical studies, the data are sparse. Thus, neither procedures nor assay method for FNA-Tg have been standardized. Summary FNA-Tg measurement is the more accurate tool to detect neck recurrences and metastases from DTC. Providing strict standardization of preanalytical and analytical phase, FNA-Tg may suffice to confirm or exclude neck DTC recurrence in patients with concurrent well differentiated papillary cancer type, suspicious neck ultrasound findings and increased serum thyroglobulin after thyroidectomy. On the contrary, FNA-Tg accuracy increases by adding cytological examination when FNA is performed before thyroidectomy, in patients with more aggressive histological types, and if low-undetectable serum thyroglobulin and/or positive serum antithyroglobulin antibodies occur.
Specific heat of helium confined to a 57- &mgr;m planar geometry near the lambda point

We report measurements of the specific heat of liquid helium confined to 57-&mgr;m planar gaps extending to within a few nanokelvin of the bulk lambda transition. The data are in fair agreement with Monte Carlo estimates for finite-size effects and with renormalization-group-theory predictions above the transition. Far from the transition, we find surface specific heat exponents, alpha(s) = 0.64+/-0.05 below, and 0.65+/-0.2 above, which compare well with the prediction of 0.658. Comparison with other recent data on small length scales shows some areas of agreement.
Activation of respiratory muscles does not occur during cold-submergence in bullfrogs, Lithobates catesbeianus

ABSTRACT Semiaquatic frogs may not breathe air for several months because they overwinter in ice-covered ponds. In contrast to many vertebrates that experience decreased motor performance after inactivity, bullfrogs, Lithobates catesbeianus, retain functional respiratory motor processes following cold-submergence. Unlike mammalian hibernators with unloaded limb muscles and inactive locomotor systems, respiratory mechanics of frogs counterintuitively allow for ventilatory maneuvers when submerged. Thus, we hypothesized that bullfrogs generate respiratory motor patterns during cold-submergence to avoid disuse and preserve motor performance. Accordingly, we measured activity of respiratory muscles (buccal floor compressor and glottal dilator) via electromyography in freely behaving bullfrogs at 20 and 2°C. Although we confirm that ventilation cycles occur underwater at 20°C, bullfrogs did not activate either respiratory muscle when submerged acutely or chronically at 2°C. We conclude that cold-submerged bullfrogs endure respiratory motor inactivity, implying that other mechanisms, excluding underwater muscle activation, maintain a functional respiratory motor system throughout overwintering. Summary: Persistent neuromotor activity of respiratory muscles in bullfrogs during aquatic overwintering is unlikely to underlie normal respiratory motor function after months without lung breathing, despite having respiratory mechanics that operate underwater.
Impact of Structured Education on Knowledge and Practice Regarding Venous Access Device Care among Nurses

Venous access devices are used to manage patients undergoing long term treatment, especially chemotherapy. Though it has many advantages, they are not free from complications. Sepsis, thrombotic complications, local tissue damages are more common complications. Aim: the main of study was to assess the impact of structure education on knowledge and practice regarding venous access device among nurses. Methodology: The quasi-experimental study with pre-test-post-test design was used. The sample size for the study was 60. In this, 30 were in experimental group and 30 were in control group . The samples were selected from the cancer units. Findings: The maximum of 43.33 % of samples scored between 0-13 (Poor) in the knowledge pre-test before structured education to the experimental group and 65 % samples scored between 18-25 ( Good) in the post-test after structured to experimental group. In control group, the mean score of knowledge score was increased from 15.3 to 16.4 in the post test. In Experimental group of the study, the mean score of knowledge regarding venous access device care was increased from 14.6 to 21.3 in the post-test after structured education. In experimental group, the maximum of 75 % of samples scored between 14-17 (Average) in the practice pre-test before structured education and 48.33 % samples scored between 18-25 (Good) score in the practice post-test score after structured education. In control group, the mean score of practice score was increased from 15.4 to 15.5 in the post test. Conclusion:From all the above findings it can be concluded that the structured education was effective on knowledge and practice of staff nurses regarding venous access device care.
What are emotions and how are they created in the brain?

Abstract In our response, we clarify important theoretical differences between basic emotion and psychological construction approaches. We evaluate the empirical status of the basic emotion approach, addressing whether it requires brain localization, whether localization can be observed with better analytic tools, and whether evidence for basic emotions exists in other types of measures. We then revisit the issue of whether the key hypotheses of psychological construction are supported by our meta-analytic findings. We close by elaborating on commentator suggestions for future research.
Vps51 Is Part of the Yeast Vps Fifty-three Tethering Complex Essential for Retrograde Traffic from the Early Endosome and Cvt Vesicle Completion*

Autophagy, pexophagy, and the Cvt pathway are processes that deliver hydrolytic enzymes and substrates to the yeast vacuole/lysosome via double-membrane cytosolic vesicles. Whereas these pathways operate under different nutritional conditions, they all employ common machinery with only a few specific factors assisting in the choice of the delivery program and the membrane source for the sequestering vesicle. We found that the YKR020w gene product is essential for Cvt vesicle formation but not for pexophagy or induction of autophagy. Autophagosomes in the ykr020wΔ mutant, however, have a reduced size. We demonstrate that Ykr020 is a subunit of the Vps fifty-three tethering complex, composed of Vps52, Vps53, and Vps54, which is required for retrograde traffic from the early endosome back to the late Golgi, and for this reason we named it Vps51. This complex participates in a fusion event together with Tlg1 and Tlg2, two SNAREs also shown to be necessary for Cvt vesicle assembly. In particular, those factors are essential to correctly target the prApe1-Cvt19-Cvt9 complex to the preautophagosomal structure, the site of Cvt vesicle formation.
Regulation of Fibroblast Growth Factor 2 and Fibroblast Growth Factor Receptors by Transforming Growth Factor β in Human Osteoblastic MG‐63 Cells

Fibroblast growth factor 2 (FGF‐2) and its receptors (FGFRs) are important regulators of bone cell function. Although FGF‐2 is a major modulator of bone cell function, its expression and regulation in human osteoblasts have not been investigated. We examined FGF‐2 messenger RNA (mRNA) expression and regulation in the human osteosarcoma MG‐63 cells. Northern analysis revealed that MG‐63 cells expressed FGF‐2 mRNA transcripts of 7, 4, 2.2, and 1.3 kilobases (kb). In the absence of serum, treatment with transforming growth factor beta (TGF‐β; 0.1‐10 ng/ml) increased all FGF‐2 mRNA transcripts. Maximal increase was seen with 1 ng/ml of TGF‐β. TGF‐β increased FGF‐2 mRNA expression within 2 h and this was sustained for 24 h. Phorbal myristate acetate (PMA; 1 μM) also increased FGF‐2 mRNA at 6 h. Time course studies showed that TGF‐β did not significantly alter FGFR1 or FGFR2 mRNA expression in MG‐63 cells. Western blotting with anti‐human FGF‐2 revealed that MG‐63 cells synthesize three isoforms of FGF‐2 protein of ∼18, 22/23, and 24 kDa, which were increased after either 6 h or 24 h of treatment with TGF‐β. Increased FGF‐2 mRNA and protein expression in response to TGF‐β was markedly reduced by the protein kinase A (PKA) inhibitor H‐89. Immunogold labeling of MG‐63 cells treated with TGF‐β showed increased labeling for FGF‐2 and FGFR2 in the nuclei. In contrast, TGF‐β treatment significantly decreased FGFR1 labeling in the nuclei. These data show that TGF‐β regulates FGF‐2 gene expression in human osteosarcoma cells. Furthermore, TGF‐β modulates the cellular localization of FGF‐2 and its receptors.
Discrete time repetitive control for robot manipulators

The analysis and experimental implementation of a discrete-time repetitive control scheme is presented. The repetitive control structure is designed to be easily implemented on any system without modification to the existing controller. Simulation and experimental results show that the repetitive controller in conjunction with a computed-torque control or a simple proportional-derivative control law achieves good tracking performance when the desired trajectory is periodic and the period is known. <<ETX>>
Prostatectomy and Deep‐Vein Thrombosis

In a study of 50 patients who had undergone prostatectomy the incidence of deep‐vein thrombosis was measured, using the 125I‐fibrinogen test. Of these, 12 (24 per cent) developed deep‐vein thrombosis. This preliminary study showed that in patients who had had a transurethral resection the incidence of deep‐vein thrombosis was 6.8 per cent, while in patients who had had a retropubic prostatectomy it was 47.6 per cent.
New ionization processes and applications for use in mass spectrometry

Abstract Mass spectrometry (MS) continues to improve at a rapid pace as most prominently witnessed for mass analyzers and fragmentation technology. Ionization methods have also seen resurgence with ambient ionization approaches gaining a foothold because they often provide a convenient and direct means of sample analysis. Nevertheless, a vast majority of biological analyses using MS apply electrospray ionization or matrix-assisted laser desorption/ionization, methods introduced in the 1980s, or variants thereof. To further advance applications by MS such as protein characterization, and, for example, addressing their location within specific cell types, the progress in mass analyzer and fragmentation technology needs to be matched with similar advances in ionization technology. It is imperative to seek ionization methods that more efficiently convert molecules, to gas-phase ions in a way that allows high transfer efficiency to the mass analyzer and subsequently the detector to achieve a more complete picture of sample composition. This review provides a snapshot of fundamental aspects of new ionization methods and potential biological and medical applications.
Cumulative effects of concussion in amateur athletes

Primary objective: To examine the possibility that athletes with multiple concussions show cumulative effects of injury. Methods and procedures: Amateur athletes with a history of three or more concussions were carefully matched (gender, age, education and sport) with athletes with no prior concussions. All completed a computerized neuropsychological test battery at preseason (ImPACT) and then within 5 days of sustaining a concussion (mean = 1.7 days). Main outcomes and results: There were differences between groups in symptom reporting and memory performance. At baseline (i.e. preseason), athletes with multiple concussions reported more symptoms than athletes with no history of concussion. At approximately 2 days post-injury, athletes with multiple concussions scored significantly lower on memory testing than athletes with a single concussion. Athletes with multiple concussions were 7.7 times more likely to demonstrate a major drop in memory performance than athletes with no previous concussions. Conclusions: This study provides preliminary evidence to suggest that athletes with multiple concussions might have cumulative effects.
Two‐hybrid analysis of domain interactions involving NtrB and NtrC two‐component regulators

Signal transduction by two‐component regulatory systems involves phosphorylation of the receiver domain of a response regulator by the transmitter domain of the cognate histidine kinase. In the NtrBC system, phosphorylation of NtrC by NtrB results in transcriptional activation of nitrogen‐regulated genes. We have used the yeast two‐hybrid system to probe interactions between domains of the NtrB and NtrC proteins from Klebsiella pneumoniae. We constructed fusions from each of a series of proteins or protein domains to the activation and the DNA‐binding domains of GAL4 and analysed expression of GAL1:lacZ and GAL1:HIS3 reporters in yeast. The DNA‐binding domain of NtrC and the so‐called sensor domain of NtrB appeared to provide the major determinants for dimerization of the fusion proteins. A strong and specific interaction was also shown between NtrB and NtrC, localized to the HN region of the NtrB transmitter module and to the NtrC receiver domain, whereas other domains of these proteins do not appear to contribute to the recognition specificity. The results presented here indicate that communication between two‐component partners also involves protein–protein interactions that can be detected in vivo, suggesting that the yeast two‐hybrid system is a powerful genetic tool for identifying functional partners of prokaryotic signal transduction pathways.
Semiautomated Model Validation of Power Plant Equipment Using Online Measurements

Model validation of power plant equipment is expected to be mandated imminently by the North American Electric Reliability Corporation. These standards will result in a great need for performing model validation for a large fleet of existing and future power plants. The historic approach to model validation of synchronous generators has typically been a battery of offline tests. In addition, the process of validation depends on a trial and error series of simulations, comparing the results of such simulations with measured test data, to gradually tend toward a validated model and its parameters. Such a method presents significant challenges for application on a large fleet of units. This paper documents a practical approach to model validation. The method is based on collecting online data from the generating unit, typically near or at base-load. Data are collected either from digital-fault recorders capturing system disturbances, or from digital excitation system for an imposed small voltage-reference step. The data are then used in a software tool to perform model validation using an automated optimization algorithm-the entire process may be said to be semiautomated. The benefits are explained in the paper through actual examples of the application.
IT-Enabled Social Innovation in China's Taobao Villages: The Role of Netrepreneurs

We present a model of IT-enabled social innovation. Our model draws on the theoretical lens of social shaping of technology and the role of villagers-turned-netrepreneurs, as reference actors in the context of rural e-commerce development. The model is built on stage-wise observations of intermediary roles that villagers play and how these roles enhance or decrease in importance in the biography of rural to e-commerce villages’ transformations across China in recent years. In this research-in-progress paper, we present a case study of Daji, China’s first “Taobao performance costumes town”, located in rural Shandong province. Our preliminary model prescribes three mechanisms− advancing, authenticating and attaching−that are enacted by reference actors in the process of negotiating rural e-commerce development in their communities, and also resurrect heritage and community identity. Our model builds on conjectural discussion in recent IS research on the expanding role of the users in influencing the development of IT-enabled social innovations.
NEB in Analysis of Natural Image 8 × 8 and 9 × 9 High-contrast Patches

In this paper we use the nudged elastic band tech-nique from computational chemistry to investigate sampled high-dimensional data from a natural image database. We randomly sample 8 × 8 and 9 × 9 high-contrast patches of natural images and create a density estimator believed as a Morse function. By the Morse function we build one-dimensional cell complexes from the sampled data. Using one-dimensional cell complexes, we identify topological properties of 8 × 8 and 9 × 9 high-contrast natural image patches, we show that there exist two kinds of subsets of high-contrast 8 × 8 and 9 × 9 patches modeled as a circle, by the new method we confirm some results obtained through the method of computational topology.
