3‐D uncertainty‐based topographic change detection with structure‐from‐motion photogrammetry: precision maps for ground control and directly georeferenced surveys
Authors: James Mike R. , Robson Stuart , Smith Mark W. 
Published: February 2017

AbstractStructure‐from‐motion (SfM) photogrammetry is revolutionising the collection of detailed topographic data, but insight into geomorphological processes is currently restricted by our limited understanding of SfM survey uncertainties. Here, we present an approach that, for the first time, specifically accounts for the spatially variable precision inherent to photo‐based surveys, and enables confidence‐bounded quantification of 3D topographic change. The method uses novel 3D precision maps that describe the 3D photogrammetric and georeferencing uncertainty, and determines change through an adapted state‐of‐the‐art fully 3D point‐cloud comparison (M3C2), which is particularly valuable for complex topography. We introduce this method by: (1) using simulated UAV surveys, processed in photogrammetric software, to illustrate the spatial variability of precision and the relative influences of photogrammetric (e.g. image network geometry, tie point quality) and georeferencing (e.g. control measurement) considerations; (2) we then present a new Monte Carlo procedure for deriving this information using standard SfM software and integrate it into confidence‐bounded change detection; before (3) demonstrating geomorphological application in which we use benchmark TLS data for validation and then estimate sediment budgets through differencing annual SfM surveys of an eroding badland. We show how 3D precision maps enable more probable erosion patterns to be identified than existing analyses, and how a similar overall survey precision could have been achieved with direct survey georeferencing for camera position data with precision half as good as the GCPs'. Where precision is limited by weak georeferencing (e.g. camera positions with multi‐metre precision, such as from a consumer UAV), then overall survey precision can scale as n‐½ of the control precision (n = number of images). Our method also provides variance–covariance information for all parameters. Thus, we now open the door for SfM practitioners to use the comprehensive analyses that have underpinned rigorous photogrammetric approaches over the last half‐century.

Water requirements and drinking rates of homing pigeons: A consideration for exposure risk of migratory birds
Authors: Perez Cristina R , Moye John K , Pritsos Chris A 
Published: February 2017

Abstract

Access to water along a bird's migratory flyway is essential during the vital process of migration. Because of the scarcity of water in some environments, there is potential for migratory birds to encounter and drink from contaminated bodies of water. Ingestion of contaminated water may cause injury and compromise flying ability, leading to a disruption of migration. To determine injury to birds from potential exposure, it is essential to know not only the concentration of a given contaminant in the water but also the quantity and rate of water consumption by the birds. Homing pigeons (Columba livia) were used in a series of experiments to determine differences in drinking behavior after various flights and after periods of resting. Results from the present study demonstrate that homing pigeons’ water consumption is dramatically different when assessed according to activity, flight distance, and time elapsed after flight. This suggests that the drinking rates of birds during migration are extremely important and much greater than estimated using traditional exposure assessment procedures. Thus, exposure to contaminants via drinking water may be greatly underestimated, and the rate of water consumption should be considered when estimating potential exposure risk to avian species.

Key Points
Homing pigeon drinking water rates are greater during periods of flight than during periods of inactivity. Drinking rates increase with flight distance, and the highest rates of water consumption were observed during the first 30 minutes immediately after flight. Migratory birds are likely to encounter contaminated sources of water along their migratory flyway, and the ability of birds to consume large amounts of water in a short time period creates increased potential for exposure, subsequent injury, and compromised flying ability, likely disrupting migration. Assessing risk exposure of bird species from contaminated water bodies based on current methods likely underestimates this injury.

Published: February 2017

BackgroundThe role of factor VII (FVII) as a risk factor in myocardial infarction (MI) has been the subject of numerous studies. However, it remains uncertain whether the FVII levels are associated with development of MI.MethodsThe subjects were 4142 men and women whose activated FVII (FVIIa) and FVII coagulant (FVIIc) levels were measured in the Jichi Medical School Cohort Study. Subjects were divided into tertiles by FVIIa and FVIIc levels, and Cox's proportional hazard model was used to calculate hazard ratios (HRs) for MI.ResultsThe multivariate‐adjusted HRs (95% confidential interval [CI]) for FVIIa in men were 0.67 (0.67‐1.78) in tertile 2 (T2), and 0.52 (0.17‐1.60) in T3. In women, the multivariate‐adjusted HRs (95% CI) were 0.18 (0.02‐1.60) in T2, and 0.39 (0.07‐2.20) in T3. The multivariate‐adjusted HRs (95% CI) for FVIIc in men were 0.54 (0.21‐1.36) in T2, and 0.20 (0.04‐0.91) in T3. In women, the multivariate‐adjusted HRs (95% CI) were 0.44 (0.07‐2.85) in T2, and 0.35 (0.06‐2.22) in T3. We used T1 as a reference for all measures.ConclusionOur findings revealed a significant association between low FVIIc level and incidence of MI in men. The FVIIa and FVIIc levels were inversely related to increased MI risk, but did not reach statistical significance. Future studies are needed to confirm this association.

Published: February 2017

AbstractBACKGROUNDThe quality of coffee depends not only on the contents of healthy compounds but also on its contamination with microorganisms that can produce mycotoxins during development, harvesting, preparation, transport and storage.RESULTSThe antioxidant activity of green coffee brews measured in this study by ABTS, DPPH and Folin–Ciocalteu assays showed that coffee extracts from Robusta beans possessed higher activity in all assays than extracts from Arabica beans. The occurrence of ochratoxin A and aflatoxins (B1, B2, G1 and G2) in green coffee beans was studied using liquid chromatography/mass spectrometry. Apart from mycotoxins, the content of ergosterol as a marker indicating fungal occurrence was also determined. Among aflatoxins, aflatoxin B1 was the dominant mycotoxin in coffee bean samples, with the highest level at 17.45 ng g−1. Ochratoxin A was detected in four samples at levels ranging from 1.27 to 4.34 ng g−1, and fungi potentially producing this toxin, namely Aspergillus oryzae, Alternaria sp., Aspergillus foetidus, Aspergillus tamarii and Penicillium citrinum, were isolated.CONCLUSIONSteaming and decaffeination of coffee beans increased antioxidant activities of brews in comparison with those prepared from unprocessed beans. Although toxins can be quantified in green coffee beans and novel fungi were isolated, their concentrations are acceptable according to legal limits. © 2017 Society of Chemical Industry

Published: February 2017

Background and ObjectivesTo evaluate the results of testis‐sparing surgery (TSS) in patients, with small testicular lesions and a normal contralateral testicle.MethodsIn all, 28 patients were treated with TSS for small testicular lesions and a normal contralateral testicle. TSS was considered in patients with testicular lesions smaller than 2 cm and no evidence of metastatic disease.ResultsThe mean age of patients was 35.3 ± 7.3 years, while the mean diameter of the testicular lesions was 11.4 ± 3.7 mm. After pathological examination, 18 patients (64.3%) were diagnosed with stromal tumors and miscellaneous lesions, while 10 (35.7%) had a germ cell tumor. The median follow‐up time for the former group was 33 months and no recurrences were observed. In one patient with germ cell tumor, immediate orchiectomy was performed, while the remaining nine were followed‐up (median time, 45 months). One patient developed local recurrence after 39 months.ConclusionsExcellent outcomes for benign lesions could be achieved using TSS. TSS could be offered safely in highly selected patients with germ cell tumors, specifically within a clinical trial but there is more data needed regarding the potential risks and benefits. J. Surg.

Published: February 2017

BACKGROUNDThe aim of this study is to describe the trends and variations in the global burden of colorectal cancer (CRC).METHODSData (2012‐2030) relating to CRC was extracted from GLOBOCAN 2012 database and analyzed.RESULTSThe results of our study demonstrate a rising global burden of colorectal cancer which persists until the year 2035 and likely beyond. The rise in the global burden is not uniform with significant variations influenced by geographic location, socio‐economic status, age, and gender. Although the EURO region has the highest burden, Asia as a continent continues to bear the heaviest brunt of the disease. Although the burden of disease is higher in more developed regions, mortality is considerably higher in less developed regions and this gap widens over the next two decades. The disease predominantly affects the male gender across all regions of the world. Age has a complex relation with the burden of CRC and is affected by the cross‐influences relating to socio‐economic status.CONCLUSIONSThe results of our study demonstrate a rising global burden of CRC with some unique variations. Knowledge of this data can increase awareness and help strategic targeting of efforts and resources.
Magnetic N‐doped mesoporous carbon as an adsorbent for the magnetic solid‐phase extraction of phthalate esters from soft drinks
Authors: Li Menghua , Jiao Caina , Yang Xiumin , Wang Chun , Wu Qiuhua , Wang Zhi 
Published: February 2017

A new kind of magnetic N‐doped mesoporous carbon was prepared by the one‐step carbonization of a hybrid precursor (glucose, melamine, and iron chloride) in a N2 atmosphere with a eutectic salt (KCl/ZnCl2) as the porogen. The obtained magnetic N‐doped mesoporous carbon showed excellent characteristics, such as strong magnetic response, high surface area, large pore volume, and abundant π‐electron system, which endow it with a great potential as a magnetic solid‐phase extraction adsorbent. To evaluate its adsorption performance, the magnetic N‐doped mesoporous carbon was used for the extraction of three phthalate esters from soft drink samples followed by high‐performance liquid chromatographic analysis. Under the optimum conditions, the developed method showed a good linearity (1.0–120.0 ng/mL), low limit of detection (0.1–0.3 ng/mL, S/N = 3), and good recoveries (83.2–119.0%) in soft drink samples. The results indicated that the magnetic N‐doped mesoporous carbon has an excellent adsorption capacity for phthalate esters and the present method is simple, accurate, and highly efficient for the extraction and determination of phthalate esters in complex matrix samples.

Published: February 2017

AbstractIntroductionThe pace of medical discovery is accelerating to the point where caregivers can no longer keep up with the latest diagnosis or treatment recommendations. At the same time, sophisticated and complex electronic medical records and clinical systems are generating increasing volumes of patient data, making it difficult to find the important information required for patient care. To address these challenges, Mayo Clinic established a knowledge management program to curate, store, and disseminate clinical knowledge.MethodsThe authors describe AskMayoExpert, a point‐of‐care knowledge delivery system, and discuss the process by which the clinical knowledge is captured, vetted by clinicians, annotated, and stored in a knowledge content management system. The content generated for AskMayoExpert is considered to be core clinical content and serves as the basis for knowledge diffusion to clinicians through order sets and clinical decision support rules, as well as to patients and consumers through patient education materials and internet content. The authors evaluate alternative approaches for better integration of knowledge into the clinical workflow through development of computer‐interpretable care process models.ResultsEach of the modeling approaches evaluated has shown promise. However, because each of them addresses the problem from a different perspective, there have been challenges in coming to a common model. Given the current state of guideline modeling and the need for a near‐term solution, Mayo Clinic will likely focus on breaking down care process models into components and on standardization of those components, deferring, for now, the orchestration.ConclusionA point‐of‐care knowledge resource developed to support an individualized approach to patient care has grown into a formal knowledge management program. Translation of the textual knowledge into machine executable knowledge will allow integration of the knowledge with specific patient data and truly serve as a colleague and mentor for the physicians taking care of the patient.
Consumer Preference for Status Symbolism of Clothing: The Case of the Czech Republic
Authors: Millan Elena , Mittal Banwari 
Published: February 2017

ABSTRACTDuring the past three decades, consumer demand for luxury goods has been growing on a global scale. The luxury and status market base has expanded beyond the traditional affluent consumer segment to include an increasingly heterogeneous group of consumers. Despite the substantial size, greater reach, and significant growth of the luxury goods market, status consumption has been treated as an atypical and peripheral subject in consumer research. The authors develop a conceptual model of psychological determinants of status seeking through consumption. The model considers the effects of three general traits (namely, status concern (SC), public self‐consciousness (PSC), and self‐esteem (SE)) and one consumption‐related consumer trait (namely, susceptibility to normative social influence (SNSI)) on preference for status meaning, which in turn influences consumer interest in the product. The conceptual model is tested with data from a survey of 1000+ respondents drawn from the Czech Republic, a country where the recent market liberalization has unleashed an inflow of luxury goods from marketers from the West. Face‐to‐face home‐based structured interviews were conducted by an international market research agency. The hypothesized causal relationships are all supported. The effects of SC, PSC, and SE on SNSI and preference for status meaning (PSM) are significant and in the expected direction. Additionally, SNSI is found to exert a significant positive influence on PSM, and these two constructs, in turn, have significant positive effects on consumer interest in clothing. The conceptual model and empirical evidence enhance the existing knowledge of the antecedents and outcomes of status consumption. The study advances a better understanding of the psychology of consumer adoption of status consumption; equally important, it also highlights the value of extending consumer theories from established to emerging market economies and back again from still‐evolving to long‐standing marketplaces.
Effects of Matching and Mismatching Messages on Purchase Avoidance Behavior following Major Disasters
Authors: Kudo Daisuke , Nagaya Kazuhisa 
Published: February 2017

ABSTRACTFollowing major disasters, purchase avoidance behavior toward products that are caused by stigma often results. For example, after the Tohoku Earthquake and Fukushima Daiichi Nuclear Disaster, consumers have avoided products from Fukushima. Attempts have been made to diminish this purchase avoidance behavior, but they have been found to be ineffective. The reasons for ineffectiveness of strategies within this context were empirically examined based on matching and mismatching effects of messages. In two studies (Study 1, N = 113; Study 2, N = 364), the effects of affective messages and cognitive messages were compared, and the effectiveness of affective messages was found to be consistently weaker than that of cognitive messages. Message producers often present affective messages with the expectation of observing the matching effect. However, findings suggest that these presentation strategies will fail, and that the mismatching effect should be used instead. The best method of message presentation to reduce purchase avoidance behavior in a disaster area is discussed.
Reversible Parkinsonism and Rapidly Progressive Dementia Due to Dural Arteriovenous Fistula: Case Series and Literature Review
Authors: Lai Joshua , Heran Manraj K.S. , Stoessl A. Jon , Gooderham Peter A. 
Published: February 2017

AbstractBackgroundDural arteriovenous fistula (dAVF) rarely presents with a syndrome of reversible parkinsonism and rapidly progressive dementia, which has been described in 19 patients to date. However, its presenting features, pathophysiology, and response to treatment have not been reviewed.MethodsWe report the clinical course and treatment of two novel patients with this syndrome.ResultsDespite severe presentations, both patients recovered fully after fistula obliteration.ConclusionsAtypical parkinsonism with early cognitive changes and other focal neurological signs, along with features such as pulsatile tinnitus or worsening headache, should raise the possibility of dAVF. When treated, this syndrome is nearly always reversible, highlighting the importance of early diagnosis.
A time‐efficient acquisition protocol for multipurpose diffusion‐weighted microstructural imaging at 7 Tesla
Authors: Sepehrband Farshid , O'Brien Kieran , Barth Markus 
Published: February 2017

PurposeSeveral diffusion‐weighted MRI techniques have been developed and validated during the past 2 decades. While offering various neuroanatomical inferences, these techniques differ in their proposed optimal acquisition design, preventing clinicians and researchers benefiting from all potential inference methods, particularly when limited time is available. This study reports an optimal design that enables for a time‐efficient diffusion‐weighted MRI acquisition scheme at 7 Tesla. The primary audience of this article is the typical end user, interested in diffusion‐weighted microstructural imaging at 7 Tesla.MethodsWe tested b‐values in the range of 700 to 3000 s/mm2 with different number of angular diffusion‐encoding samples, against a data‐driven “gold standard.”ResultsThe suggested design is a protocol with b‐values of 1000 and 2500 s/mm2, with 25 and 50 samples, uniformly distributed over two shells. We also report a range of protocols in which the results of fitting microstructural models to the diffusion‐weighted data had high correlation with the gold standard.ConclusionWe estimated minimum acquisition requirements that enable diffusion tensor imaging, higher angular resolution diffusion‐weighted imaging, neurite orientation dispersion, and density imaging and white matter tract integrity across whole brain with isotropic resolution of 1.8 mm in less than 11 min.

Published: February 2017

BACKGROUNDProstate is highly affected by aging, which lead to inflammatory disorders that can predispose to cancer development. Chemoprevention has emerged as a new therapeutic approach, intensifying studies evaluating the biological properties of new compounds. The aim of this study was to characterize the inflammatory responses in the prostate ventral lobe from senile mice treated with Goniothalamin (GTN), a promising natural compound with anti‐inflammatory and antiproliferative properties. Its activity was compared to Celecoxib, an established nonsteroidal anti‐inflammatory drug (NSAID).METHODSThe animals were divided into: Control groups; Young (18‐week‐old FVB), Senile (52‐week‐old FVB). Treated groups: Senile‐Goniothalamin (150 mg/kg orally), Senile‐Celecoxib (10 mg/kg orally). The ventral lobe was collected after 4 weeks for light microscopy, immunohistochemistry, ELISA, and Western blotting analysis.RESULTSBoth treatments were efficient in controlling the inflammatory process in the prostate from senile mice, maintaining the glandular morphology integrity. GTN reduced all inflammatory mediators evaluated (TNF‐α, COX‐2, iNOS) and different from Celecoxib, it also decreased the protein levels of NF‐kB and p‐NF‐kB.CONCLUSIONSFinally, GTN and Celecoxib controlled inflammation in the prostate, and sensitized the senescent microenvironment to anti‐inflammatory stimuli. Thus, both treatments are indicated as potential drugs in the prostatic diseases prevention during senescence. Prostate 77:838–848, 2017. © 2017 Wiley Periodicals, Inc.
Double‐stranded RNA delivery through soaking mediates silencing of the muscle protein 20 and increases mortality to the Asian citrus psyllid, Diaphorina citri
Authors: Yu Xiudao , Gowda Siddarame , Killiny Nabil 
Published: February 2017

AbstractBACKGROUNDAsian citrus psyllid, Diaphorina citri Kuwayama, is the most important economic pest of citrus because it transmits Candidatus Liberibacter asiaticus (CLas), the causal agent of huanglongbing (HLB). Silencing genes by RNA interference (RNAi) is a promising approach for controlling D. citri. RNAi‐based insect management strategies depend on the selection of suitable target genes.RESULTSThe muscle protein 20 gene DcMP20 was characterized from D. citri in an effort to impair proper muscle development through RNAi. Phylogenetic analysis showed that DcMP20 was more closely related to MP20 from Drosophila compared with its counterpart from other insect species. Developmental expression analysis revealed that transcription of DcMP20 was development dependent and reached a maximum level in the last instar (fourth–fifth) of the nymphal stage. The extent of RNAi in D. citri was dose dependent, with dsRNA‐DcMP20 at 75 ng µL−1 being sufficient to knock down endogenous DcMP20 expression, which resulted in significant mortality and reduced body weight that positively correlated with the silencing of DcMP20. No effect was found when dsRNA‐GFP or water was used, indicating the specific effect of dsRNA‐DcMP20.CONCLUSIONOur results suggest that dsRNA can be delivered to D. citri through soaking, and DcMP20 is an effective RNAi target to be used in the management of D. citri. © 2017 Society of Chemical Industry
