To address the unique challenges in the diagnosis and management of small pheochromocytomas, the authors performed a retrospective study of 24 patients with small pheochromocytomas (≤3 cm) treated between 1995 and 2011, using 51 patients with larger pheochromocytomas (>3 cm) as controls. Patient demographics were similar between the two groups. Small pheochromocytomas presented mainly as adrenal mass and hypertension and their major complication was hypertensive crisis during unrelated procedures in 4 patients (17%). Hypertension was improved in a quarter of the patients after pheochromocytoma resection. The biochemical marker levels in patients with small pheochromocytomas were generally lower than those with larger tumors and half of the patients exhibited modestly elevated or normal levels. The authors conclude that small pheochromocytomas are frequent and may not contribute to baseline hypertension, but can cause hypertensive crisis during unrelated medical procedures. Small pheochromocytomas should be removed to prevent hypertensive crisis and future complications of pheochromocytoma.

Clinical inertia is a major contributor to poor blood pressure (BP) control. The authors tested the effectiveness of an intervention targeting physician, patient, and office system factors with regard to outcomes of clinical inertia and BP control. A total of 591 adult primary care patients with elevated BP (mean systolic BP ≥140 mm Hg or mean diastolic BP ≥90 mm Hg) were randomized to intervention or usual care. An outreach coordinator raised patient and provider awareness of unmet BP goals, arranged BP‐focused primary care clinic visits, and furnished providers with treatment decision support. The intervention reduced clinical inertia (−29% vs −11%, P=.001). Nonetheless, change in BP did not differ between intervention and usual care (−10.1/−4.1 mm Hg vs −9.1/−4.5 mm Hg, P=.50 and 0.71 for systolic and diastolic BP, respectively). Future primary care–focused interventions might benefit from the use of specific medication titration protocols, treatment adherence support, and more sustained patient follow‐up visits.

Medication prescribing practice changed following the publications of the Antihypertensive and Lipid‐Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) in 2002 and the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC 7) in 2003. Few data are available on changes in hypertension control rates for patients initiating antihypertensive treatment before and after these publications. The authors compared systolic and diastolic blood pressure (SBP and DBP) levels and hypertension control (SBP <140 mm Hg and DBP <90 mm Hg) rates in patients initiating antihypertensive treatment in a large managed care organization during 2 time periods: July 1, 2001, to June 30, 2002 (n=322); and July 1, 2003, to June 30, 2004 (n=323). The blood pressure reduction associated with antihypertensive medication initiation was similar in 2001–2002 and 2003–2004 (−11.9 and −10.5 mm Hg, respectively, P=.251 for SBP; −6.9 and −5.9 mm Hg, respectively, P=.160 for DBP). The mean SBP and DBP prior to treatment were significantly lower in 2003–2004 vs 2001–2002 (145.4 vs 151.3 mm Hg, P<.001 for SBP; 87.6 vs 90.1 mm Hg, P<.002 for DBP). Hypertension control rates increased from 38.0% to 50.2% (P=.005) from 2001–2002 to 2003–2004. Lower pretreatment SBP and DBP explained hypertension control improvement over time. In this real‐world clinic population, antihypertensive treatment was initiated at lower blood pressure levels following publication of ALLHAT and JNC 7, resulting in substantial improvements in hypertension control rates.

Authors: Barañano Anne E. , Keane Pearse A. , Ruiz‐Garcia Humberto , Walsh Alexander C. , Sadda Srinivas R.
Published: March 2012

Purpose:  To determine the effect of optical coherence tomography (OCT) B‐scan density on the qualitative assessment of neovascular age‐related macular degeneration (AMD).

Methods:  Data were collected from 59 patients imaged with Topcon 3D OCT‐1000 (128 B‐scans × 512 A‐scans). Custom software was used to generate less dense subsets of scans: 1/16 (eight B‐scans), 1/8 (16 B‐scans), 1/4 (32 B‐scans) and 1/2 (64 B‐scans). At each B‐scan density, scans were assessed for cystoid spaces, subretinal fluid (SRF), subretinal tissue (SRT) and pigment epithelium detachment (PED). For each sampling density, sensitivity, specificity and predictive values were calculated using the full volume scan (128 B‐scans) as the reference standard.

Results:  For cystoid spaces, the detection sensitivity was 76.3% at 1/16 density; this rose to 89.5% with a 1/4 density. For SRF, the detection sensitivity was 75.0% at a 1/16 density; this increased to 91.1% with 1/4 density. For PED, even at the lowest sampling density (1/16) the detection sensitivity was 86.4%; this rose to 94.9% at 1/4 density. For SRT, detection sensitivity at a 1/16 density was 64.7% and only rose above 90% with the densest sampling subset (1/2).

Conclusions:  Use of scanning protocols with reduced sampling densities resulted in decreased detection of key features of neovascular AMD; despite this, a sampling density reduced to 1/4 appeared to allow accurate assessment for most features. Current management of neovascular AMD is dependent on qualitative assessment of OCT images; with the recent proliferation of OCT systems, optimization and standardization of scanning protocols may be of value.

Authors: Kumari Niraj , Kapoor Vinay K. , Krishnani Narendra , Kumar Kamlesh , Kumar Baitha Dinesh , Behari Anu
Published: March 2012

Background and aim: Microsatellite instability and fragile histidine triad (FHIT) loss have been seen to be involved in gallbladder carcinogenesis. We studied expression loss of mismatch repair (MMR) proteins and loss of FHIT expression in gallbladder cancer by immunohistochemistry using antibodies against MLH1, MSH2 and MSH6 proteins. Methods: One hundred and two consecutive cases of gallbladder cancer were retrospectively collected and expression of MLH1, MSH2 and MSH6 and FHIT protein was studied. The expression pattern was correlated with various clinicopathologic parameters and survival. Results: Expression loss of MMR proteins was found in 52.9% and loss of FHIT expression was found in 45% cases of gallbladder cancer. Loss of FHIT expression was seen in 12% of dysplasia associated with carcinoma. Expression loss of MMR proteins was found in 16% of dysplasia associated with chronic cholecystitis and 32.6% of dysplasia associated with carcinoma. Expression loss of MMR proteins had significant positive correlation with tumor stage and had worse survival compared with patients with intact expression. Loss of FHIT expression was significantly correlated with both tumor grade and stage. Conclusions: Frequency of expression loss of MMR proteins and loss of FHIT expression increased from dysplasia to carcinoma suggesting that both these abnormalities have a role in pathogenesis and occur at an early stage in carcinogenesis of gallbladder. Fifty three percent of gallbladder cancer with expression loss of MMR proteins also showed loss of FHIT expression and were frequent in advanced stage disease suggesting that reduced FHIT expression may be correlated with expression loss of MMR proteins on immunohistochemistry.
Evolution of the life cycle in land plants
Authors: QIU Yin‐Long , TAYLOR Alexander B. , McMANUS Hilary A.
Published: March 2012

Abstract All sexually reproducing eukaryotes have a life cycle consisting of a haploid and a diploid phase, marked by meiosis and syngamy (fertilization). Each phase is adapted to certain environmental conditions. In land plants, the recently reconstructed phylogeny indicates that the life cycle has evolved from a condition with a dominant free‐living haploid gametophyte to one with a dominant free‐living diploid sporophyte. The latter condition allows plants to produce more genotypic diversity by harnessing the diversity‐generating power of meiosis and fertilization, and is selectively favored as more solar energy is fixed and fed into the biosystem on earth and the environment becomes more heterogeneous entropically. Liverworts occupy an important position for understanding the origin of the diploid generation in the life cycle of land plants. Hornworts and lycophytes represent critical extant transitional groups in the change from the gametophyte to the sporophyte as the independent free‐living generation. Seed plants, with the most elaborate sporophyte and the most reduced gametophyte (except the megagametophyte in many gymnosperms), have the best developed sexual reproduction system that can be matched only by mammals among eukaryotes: an ancient and stable sex determination mechanism (heterospory) that enhances outcrossing, a highly bimodal and skewed distribution of sperm and egg numbers, a male‐driven mutation system, female specialization in mutation selection and nourishment of the offspring, and well developed internal fertilization. The study of evolution of the land plant life cycle requires a multidisciplinary approach that considers morphology, development, genetics, phylogeny, ecology, and evolution in an integrated fashion, and will deepen our understanding of plant evolution.
Clinical Significance as It Relates to Evidence‐Based Practice
Authors: Bruner Susan , Corbett Cynthia , Gates Brian , Dupler Alice
Published: March 2012

PURPOSE.  This paper analyzes the concept of clinical significance (CS) in relation to evidence‐based practice (EBP). The purpose is to show that CS terminology is inconsistent in the nursing literature. It is argued that nursing outcomes and interventions that include findings of CS are difficult to interpret due to lack of an operational definition. It is further argued that the absence of a consistent operational definition is incompatible with EBPs which require standardization of terminology.

DATA SOURCES.  The current literature and research studies, particularly from the electronic databases Cumulative Index to Nursing and Allied Health Literature, ISI Web of Knowledge, PubMed, and Cochrane Database of Systematic Reviews.

DATA SYNTHESIS.  The disparate uses of CS negatively impact standardizing and quantifying research outcomes to discern EBPs. The authors propose a definition of CS inclusive of the multifarious uses that were revealed in the literature, and conclude that there is a need for professional nursing consensus to define the term. A standard operational definition of CS would enable consistency as clinicians interpret research findings and facilitate translating research to practice.

CONCLUSIONS.  Given the centrality of CS to interpreting research findings and applying them to practice, there is a need to solidify the terminology of and measurements for CS in nursing. National nursing agencies, including The National Institute for Nursing Research and Sigma Theta Tau International, should make standardizing CS a high priority for targeted funding. One method of doing so would be to support a consensus convergence to review and select the optimal measures of CS for nursing research. Research to increase knowledge about what constitutes measurement and change, or CS from the patient perspective is needed. Editors and peer reviewers should encourage authors to include a discussion of CS. Discussions of CS should receive greater emphasis in research journals. It is hoped that the preliminary findings from the concept analysis presented in this article will facilitate the work of such a consensus forum.

IMPLICATIONS FOR NURSING PRACTICE.  The most immediate and tangible advantages to a common conceptual definition and meaning of CS terminologies by nursing, regardless of which definition is selected, are less confusion and more clarity. Ultimately, the most enduring benefit of a common conceptual definition and measurement for CS is the bridge it provides between research and practice, and the facility with which it promotes the integration of research into EBP.
Branded food references in children's magazines: ‘advertisements’ are the tip of the iceberg
Authors: Jones S. C. , Gregory P. , Kervin L.
Published: March 2012

Objective

While children's magazines ‘blur the lines’ between editorial content and advertising, this medium has escaped the calls for government restrictions that are currently associated with food advertisements aired during children's television programming. The aim of this study was to address significant gaps in the evidence base in relation to commercial food messages in children's magazines by systematically investigating the nature and extent of food advertising and promotions over a 12‐month period.

Method

All issues of Australian children's magazines published in the calendar year 2009 were examined for references to foods or beverages.

Results

Approximately 16% of the 1678 food references identified were portrayals of branded food products (or food brands). However, only 83 of these 269 were clearly identified as advertisements. Of these 269 branded food references, 86% were for non‐core (broadly, less healthy) foods, including all but seven of the advertisements.

Conclusions

It appears that recent reductions in televised promotions for non‐core foods, and industry initiatives to reduce the targeting of children, have not carried through to magazine advertising. This study adds to the evidence base that the marketing of unhealthy food to children is widespread, and often covert, and supports public health calls for the strengthening of advertising regulation.

Authors: Babaeizadeh Mohammad , Emamzade Hadi Jafari , Salehi Shirin
Published: March 2012

Texture retrieval is a significant branch of content based image retrieval (CBIR). In this paper, the nonsubsampled contourlet transform has been used for texture image retrieval. This transform is built upon nonsubsampled pyramid and nonsubsampled directional filter banks and provides a shift-invariant, directional, multi-resolution image representation. The statistical characteristics of these directional subbands' coefficients have been used as the feature vector for texture image classification. The performance of the proposed method is compared to other texture image retrieval methods such as Gabor filter, Contourlet and Complex Directional Filter Bank (CDFB) and the experimental results show that our proposed method improves retrieval rate and outperforms other approaches in this concept.

At present, Social Networking Services (SNS) mainly focus on people's information (e.g. interests and activities) and often provide a profile for each user. However, information of things, which is also very important for people, has not been involved in current SNS. In this paper, we present a novel social network framework called Thingsbook, which merges things of the real physical world into social network through our designed mobile terminals based rchitecture of Internet of Things (IoT). With Thingsbook, every user can take participation in sensing the states of things by ubiquitous mobile terminals in a Participatory Sensing way. This paper explicitly relates the concept and implementation of Thingsbook framework. We also conduct experiments involving 20 volunteers and show the evaluation. Whether the evaluation results from our testbed or positive responses from volunteers show that Thingsbook is a promising and interesting social network model.

Authors: Huang Guimin , Cao Guoyuan , Zhou Ya
Published: March 2012

This paper proposes improvements for the method of Latent Semantic Analysis (LSA). The method is used to grade the English text automatically. But, there are still many deficiencies to be improved. Firstly, one important factor that affects the quality of LSA is the weighting method to the term-document matrix. The weighted function directly influence the results of the final score which calculated by the computer. Secondly, Probabilistic Latent Semantic Analysis (PLSA) is also applied to the automated grading model (AGM). In contrast to standard LSA by Singular Value Decomposition, the probabilistic variant has a solid statistical foundation and defines a proper generative data model. The experiments indicate that the result of the improved model has proven to be more precise.

In a specific domain, the attributes or mutual relationships connected with realistic objects are often variable dynamically and especially partially. For multi-objective categorization [2], it has been a research hotspot how to rapidly update the categorized result with the partial variations. Aiming at this problem, we propose an approach for dynamic multi-objective categorization based on the game theory, partially updating the influenced part, measuring the object's satisfaction degree by Shapley value, and improving the efficiency of calculating Shapley value by the concept of priority groups. The experimental results and the performance analyses show its better efficiency and effectiveness.

But the drawback we are encountering is annotation of those photos which is done based on visual features of the issue. In this article we are proposing a new approach to use the existing images in Photo sharing & social networking web sites originated from human annotation which makes us capable of searching family member's pictures in the most possible efficient trend. The offered algorithm is based on the familial ties which make it possible to access distant members of an individual's family via his/her close relatives regarding the fact that the applicant must run his /her search through the cannel of close family members. Our empirical evaluation highlighted the fact that this approach can be considered as another step forward to help people in their search for their beloved ones.
Analyzing Thermal and Flicker Noise Fault-Tolerance Capability of Markov Random Field Digital Circuits
Authors: Anwer Jahanzeb , Rafique U. , Fayyaz Ahmad , Aslam S. , Khalid Usman , Hamid N. H.
Published: March 2012

Markov Random Field (MRF) is known to be a fault-tolerance design technique that transforms simple CMOS to MRF-CMOS digital circuits. The transformed circuits are thus extremely noise-tolerant i.e. in presence of extreme noise interference; the output current levels have un-noticeable distortion. Although this technique has proved to be a solution for thermal noise only; we have extended the noise-tolerance capability of MRF circuits for flicker noise in this paper. The integration of thermal and flicker noise generates complex and time-consuming simulations that have been performed on Cadence-Virtuoso simulation software. Results show that the MRF design is elegant enough to cater both kinds of noise.

Published: March 2012

An extensive interest in the numerical simulation of supersonic combustion ramjet engine (scramjet) has been aroused among researchers at present. Nevertheless, the traditional serial simulation model cannot meet the requests of current researches, such as millions of computational grids and hundreds of reaction processes. In this paper, we study on a general algorithm for scramjet design, and bring about parallelization by using a two-level hybrid parallel programming model. The method includes message passing for inter-node communication (MPI) and compiler directives for intra-node parallelization (OpenMP). Finally, parallel efficiency on a China-made supercomputer with 4 to 256 cores is compared with pure MPI program. The result indicates that our hybrid parallel model is simple, effective and practical in scramjet simulation.

Exploiting Low Cost Reliability for NoC Transient Routing Error
Authors: Jiao Jiajia , Wu Peng , Fu Yuzhuo
Published: March 2012

In dominant many-core system, NoC (Network on Chip) also requires fault tolerance configuration for dependable communication. Compared with payload error, transient routing error causes fatal problems, such as packets delivered to wrong destination, network deadlock due to routing algorithm or topology forbidden. We propose a light weight redundancy method to solve transient NoC routing error: 1) configuring routing information with TMR (Triple Modular Redundancy) only for head flits; 2) exploiting inherent hardware and time redundancy for reliable routing computation. And the simulation results from cycle accurate platform show that this method brings higher routing error recovery rate with less performance loss and overhead than other fault tolerant mechanisms.

The present study examined the developmental trajectories of Mandarin-speaking children's narrative skills. 70 children aged from 3 to 9 years old in Beijing participated the study. A picture book without words was presented to children for eliciting their narratives. The results suggest that Chinese children show more elaborated narrative structures and diverse evaluation devices with age. The age of 3 to 5 is the crucial period for Chinese children to construct narrative structure. The age of 6 is the crucial period for Chinese children to use evaluation devices in narratives. Comparing with embedded evaluation, pure evaluation devices are not easy to be used in all age groups.

Observing and studying the single quantum objects, is the basis of quantum calculations because these quantum items can be used as physical locations of quantum bits. In the quantum calculations, the basis that we introduce is the q-bit. The concept of quantum parallelism leads to development of quantum algorithm like the Shore Algorithm. These algorithms, using the new mechanisms and using the abilities of quantum mechanics can solve a great deal of problems more widely with more efficiency in comparison to classical algorithms. Such algorithms are very successful in doing repetitive calculations to decode the codes. Usually in order to optimize the development of test data is evolutionary algorithms are used. In this research, we are going to develop the efficiency of this mutation test optimization algorithms that's used in the optimizer segment. Then, we want to make a comparison with common optimizer algorithms such as usual genetics and bacteriological. In the end, we want to reduce some of the problems including getting stuck in the local minimums.

Low Emissions Engine Combustor Technology Evolution
Authors: Wei Sun , Zhang Tian-Gang
Published: March 2012

Most technology development for NOx reduction has focused on emissions at low altitude. However, the need for a technological breakthrough to significantly reduce cruise emissions is also evident. There is evidence that the effect of aircraft NOx emissions at cruise could be up to four times more important than that of aircraft CO2. If this relationship is confirmed, cruise NOx will probably become a more urgent issue than low altitude NOx. The Twin-Annular Premixing Swirler (TAPS) combustor, a 4th generation low-emissions technology, offers significant NOx reduction over state-of-the-art Low Emissions Combustor (LEC) technology for both low- and cruise altitude operation.
