Summary

Photo‐reduction of O2 to water mediated by flavodiiron proteins (FDPs) represents a safety valve for the photosynthetic electron transport chain in fluctuating light. So far, the FDP‐mediated O2 photo‐reduction has been evidenced only in cyanobacteria and the moss Physcomitrella; however, a recent phylogenetic analysis of transcriptomes of photosynthetic organisms has also revealed the presence of FDP genes in several nonflowering plant groups. What remains to be clarified is whether the FDP‐dependent O2 photo‐reduction is actually operational in these organisms.

We have established a simple method for the monitoring of FDP‐mediated O2 photo‐reduction, based on the measurement of redox kinetics of P700 (the electron donor of photosystem I) upon dark‐to‐light transition. The O2 photo‐reduction is manifested as a fast re‐oxidation of P700. The validity of the method was verified by experiments with transgenic organisms, namely FDP knock‐out mutants of Synechocystis and Physcomitrella and transgenic Arabidopsis plants expressing FDPs from Physcomitrella.

We observed the fast P700 re‐oxidation in representatives of all green plant groups excluding angiosperms.

Our results provide strong evidence that the FDP‐mediated O2 photo‐reduction is functional in all nonflowering green plant groups. This finding suggests a major change in the strategy of photosynthetic regulation during the evolution of angiosperms.
Anesthesia‐induced rhabdomyolysis or malignant hyperthermia: is defining the crisis important?
Authors: Gray Rebecca M. 
Published: March 2017

SummaryAnesthesia‐induced rhabdomyolysis and malignant hyperthermia occur in response to the same agents and present with similar clinical features. Distinguishing between these diagnoses can be challenging in a clinical crisis yet making the distinction is critical as prompt appropriate management may be life‐saving, whereas delayed recognition and/or inappropriate management will almost certainly result in death. This focused review examines the differences between these conditions and focuses on the emergency management of anesthesia‐induced rhabdomyolysis.

Published: March 2017

AbstractWhen using the rational function model for the geometric orientation and geopositioning of satellite imagery, systematic bias compensation for vendor‐provided rational polynomial coefficients (RPCs) is very important. Most existing bias‐compensation models express systematic biases as a function of certain deterministic parameters, and least squares adjustment is used for estimating correction parameters. In this paper, the errors‐in‐variables model is introduced to take random errors in both the observation vector and the design matrix into consideration, based on a weighted total least squares adjustment. Experiments performed with two datasets demonstrate that the proposed method is reliable and the geopositioning accuracy improvement is better compared with a traditional least squares adjustment.
Effects of positive emotion, extraversion, and dopamine on cognitive stability‐flexibility and frontal EEG asymmetry
Authors: Wacker Jan 
Published: March 2017

AbstractThe influence of positive emotions on the balance between cognitive stability and flexibility has been suggested to (a) differ among various positive emotional/motivational states (e.g., of varying approach motivation intensity), and (b) be mediated by brain dopamine (DA). Frontal EEG alpha asymmetry (ASY) is considered an indicator of approach motivational states and may be modulated by DA. The personality trait of extraversion is strongly linked to positive emotions and is now thought to reflect DA‐based individual differences in incentive/approach motivation. The present study independently manipulated positive emotion (high approach wanting‐expectancy [WE] vs. low approach warmth‐liking [WL]) and dopamine (placebo vs. DA D2 blocker sulpiride) to examine their effects on both cognitive stability‐flexibility and emotion‐related ASY changes. The results showed numerically lower stability‐flexibility in WE versus WL under placebo and a complete reversal of this effect under the D2 blocker, no differentiation between WE and WL groups in terms of emotion‐related ASY change, but an association between self‐reported WE and WL and ASY changes toward left and right frontal cortical activity, respectively. Finally, extraversion was positively associated with both stability‐flexibility and ASY changes toward left frontal cortical activity under placebo, and these associations were completely reversed under the D2 blocker. The results (a) support a dopaminergic basis for frontal EEG asymmetry, extraversion, and the modulating effect of positive emotions on stability‐flexibility, and (b) extend previous reports of cognitive differences between introverts and extraverts.
Geological and Geochemical Characteristics of the Intrusion‐Related Vein‐Type Gold Deposits in the El Morado District, Coastal Cordillera, Northern Chile

Published: March 2017

AbstractEl Morado is the only auriferous district in the north Chilean coastal Cordillera, and has breccia‐associated Au–Fe–Cu vein‐type gold deposits, such as Beatriz and Lilianita. In addition to geological and mineralogical descriptions, geochemical characterization of the two vein deposits, and fluid inclusion and oxygen isotope analyses of the Lilianita quartz vein were performed with the objective to elucidate their ore‐forming characteristics.The two deposits are hosted in Late Jurassic to Early Cretaceous dioritic intrusions, and are characterized by the oxidized mineral association of electrum (Au75Ag25 to Au85Ag15), chalcopyrite, hematite and magnetite. Gold content of vein samples weakly correlates with Ag contents, but is not correlative with Cu contents. Fluid inclusion data of the vein quartz indicate relatively high‐trapping temperature (290 to 340°C) and low salinity (3.2 to 13.1 wt% NaCl) conditions with low‐pressure boiling evidence. The δ18O values of the corresponding quartz samples are in a narrow range of +11.1 to +12.5 ‰. These data combined with the fluid inclusion thermometric data suggest that the quartz‐mineralizing fluid with δ18O values between +4.9 and +6.2 ‰ was derived from primary magmatic water with lesser amounts of low‐temperature surface water, such as seawater or meteoric water. All these results show that the gold deposits in the El Morado district are intrusion‐related oxidized veins, which formed from magmatic‐hydrothermal fluids at relatively low‐pressure shallow conditions, compared to the Cu‐rich iron oxide–copper–gold (IOCG) vein deposits in the same province.
Fish for Dinner? Balancing Risks, Benefits, and Values in Formulating Food Consumption Advice
Authors: Rideout Karen , Kosatsky Tom 
Published: March 2017

AbstractMany and complex factors underlie seemingly simple decisions about what to eat. This is particularly so for foods such as fish, which present consumers with both risks and benefits. Advice about what type of and how much fish to consume is abundant, but that advice is often confusing or contradictory, reflecting the differing mandates and orientations of those advising. We survey a range of issues that can and should be incorporated into dietary advice, and offer tools for health agencies tasked with providing it. We argue that risks and benefits should not be limited to direct physical health. Rather, socioeconomic and community factors, unintended or indirect effects, and nonhuman‐health outcomes such as animal welfare and planetary health should also be considered and weighed. We provide examples of existing fish consumption guidance to highlight the conflicting messages that emerge when different sources of advice with singular aims of avoiding risk, gaining nutritional benefit, or sustaining fish populations are juxtaposed. We then offer tools borrowed from health and other fields to guide health agencies toward developing more comprehensive advice and targeting that advice for specific populations.
Construction Safety Risk Modeling and Simulation

Published: March 2017

AbstractBy building on a genetic‐inspired attribute‐based conceptual framework for safety risk analysis, we propose a novel approach to define, model, and simulate univariate and bivariate construction safety risk at the situational level. Our fully data‐driven techniques provide construction practitioners and academicians with an easy and automated way of getting valuable empirical insights from attribute‐based data extracted from unstructured textual injury reports. By applying our methodology on a data set of 814 injury reports, we first show the frequency‐magnitude distribution of construction safety risk to be very similar to that of many natural phenomena such as precipitation or earthquakes. Motivated by this observation, and drawing on state‐of‐the‐art techniques in hydroclimatology and insurance, we then introduce univariate and bivariate nonparametric stochastic safety risk generators based on kernel density estimators and copulas. These generators enable the user to produce large numbers of synthetic safety risk values faithful to the original data, allowing safety‐related decision making under uncertainty to be grounded on extensive empirical evidence. One of the implications of our study is that like natural phenomena, construction safety may benefit from being studied quantitatively by leveraging empirical data rather than strictly being approached through a managerial perspective using subjective data, which is the current industry standard. Finally, a side but interesting finding is that in our data set, attributes related to high energy levels (e.g., machinery, hazardous substance) and to human error (e.g., improper security of tools) emerge as strong risk shapers.
Evaluating the Mental Models Approach to Developing a Risk Communication: A Scoping Review of the Evidence

Published: March 2017

AbstractRisk communication is fundamental in ensuring people are equipped with the knowledge needed to navigate varied risks. One generally well‐regarded framework for the development of such communications is the mental models approach to risk communication (MMARC). Developed during the 1990s, the MMARC has been applied to a range of health, technological, and environmental risks. However, as yet, we know of no attempt to collate and review articles that evaluated communications developed using the MMARC. This article took a first step at addressing this gap by conducting a scoping review that aimed to begin to explore the fidelity with which the approach has been applied, explore whether there appeared to be sufficient studies to warrant a future systematic review, and identify future research questions. Although the initial search found over 100 articles explicitly applying the MMARC, only 12 of these developed a risk‐related communication that was tested against a control (and thus included in the current review). All studies reported a positive effect of the MMARC versus control communication for at least some of the outcome measures (knowledge being the most prevalent). However, there was wide variation between studies including type of control, outcomes assessed, and only five studies reported adopting a randomized design. The review highlights both the need for greater fidelity in the way future studies operationalize the MMARC approach, and suggests that a full‐scale systematic review of the MMARC literature appears justified, especially given the possibility of a large gray literature in this area.
Risk Perception and Disaster Preparedness in Immigrants and Canadian‐Born Adults: Analysis of a National Survey on Similarities and Differences

Published: March 2017

AbstractResearch has documented that immigrants tend to experience more negative consequences from natural disasters compared to native‐born individuals, although research on how immigrants perceive and respond to natural disaster risks is sparse. We investigated how risk perception and disaster preparedness for natural disasters in immigrants compared to Canadian‐born individuals as justifications for culturally‐adapted risk communication and management. To this end, we analyzed the ratings on natural disaster risk perception beliefs and preparedness behaviors from a nationally representative survey (N = 1,089). Factor analyses revealed three underlying psychological dimensions of risk perception: external responsibility for disaster management, self‐preparedness responsibility, and illusiveness of preparedness. Although immigrants and Canadian‐born individuals shared the three‐factor structure, there were differences in the salience of five risk perception beliefs. Despite these differences, immigrants and Canadian‐born individuals were similar in the level of risk perception dimensions and disaster preparedness. Regression analyses revealed self‐preparedness responsibility and external responsibility for disaster management positively predicted disaster preparedness whereas illusiveness of preparedness negatively predicted disaster preparedness in both groups. Our results showed that immigrants’ risk perception and disaster preparedness were comparable to their Canadian‐born counterparts. That is, immigrant status did not necessarily yield differences in risk perception and disaster preparedness. These social groups may benefit from a risk communication and management strategy that addresses these risk perception dimensions to increase disaster preparedness. Given the diversity of the immigrant population, the model remains to be tested by further population segmentation.

Published: March 2017

Eccentric strength training alters muscle architecture, but it is also an important factor for the prevention of hamstring injuries. The purpose was to determine the architectural adaptations of the biceps femoris long head (BFlh) after eccentric strength training with nordic hamstring exercise (NHE), followed by a subsequent detraining period. The participants in this intervention (n=23) completed a period of 13 weeks consisting of a first week of control and prior training, followed by 8 weeks of eccentric strength training with NHE, and concluding with a 4‐week period of detraining. The architectural characteristics of the BFlh were measured at rest using two‐dimensional ultrasound before (M1—week 1) and after (M2—week 9) the eccentric strength training, and at the end of the detraining period (M3—week 13). The muscle fascicle length significantly increased (t=−7.73, d=2.28, P<.001) in M2 compared to M1, as well as the muscle thickness (t=−5.23, d=1.54, P<.001), while the pennation angle presented a significant decrease (t=7.81, d=2.3, P<.001). The muscle fascicle length decreased significantly (t=6.07, d=1.79, P<.001) in M3 compared to M2, while the pennation angle showed a significant increase (t=−4.63, d=1.36, P<.001). The results provide evidence that NHE may cause alterations in the architectural conditions of the BFlh and may have practical implications for injury prevention and rehabilitation programs.

Published: March 2017

ObjectiveOur study seeks to understand the role of perceived economic stress of the Great Recession on political participation among blacks, whites, and Latinos.MethodsWe use the 2012 Collaborative Multi‐Racial Political Study and negative binomial regression to examine the impact of financial hardship on black, Hispanic, and white political participation.ResultsWe find that political participation among whites is unaffected by the Great Recession and is largely motivated by political interest. Blacks are mobilized by financial hardship even after controlling for political enthusiasm and linked fate. Hispanics have the lowest level of political participation.ConclusionOverall, we conclude that the Great Recession did affect political behavior but differently across race and ethnic groups; specifically, Hispanics were least likely to politically engage if they experienced negative consequences of the Great Recession.

AbstractObjectiveTo compare Sonicision cordless ultrasonic dissector (SCUD) to LigaSure vessel sealing device (LVSD) for laparoscopic ovariectomy (Lap OVE) in dogs.Study designRandomized, paired prospective clinical trial.AnimalsClient‐owned dogs (n = 22) presented for elective Lap OVE.MethodsDogs were randomly assigned to one of two protocols: protocol 1 required the left ovary resected using SCUD and the right ovary using LVSD; protocol 2 required the left ovary resected using LVSD and the right ovary using SCUD. Duration of ovary excision, complications, surgical smoke production, and collateral thermal damage were compared between SCUD and LVSD. Total surgery duration, postoperative convalescence, obesity, mesovarial fat score, and technique‐associated costs were also recorded.ResultsOvary excision was significantly faster with LVSD than SCUD. Surgical smoke production was significantly greater for SCUD than LVSD. Minor pedicle hemorrhage occurred 3 times with SCUD and one time with LVSD (not significantly different) and was easily corrected intraoperative. Presence of hemorrhage significantly increased ovary excision time. Technique‐associated costs were lower for SCUD than LVSD. No significant differences were found in collateral thermal damage between SCUD and LVSD. Total surgery duration and convalescence time were similar to previous reports of Lap OVE in dogs at the authors' institution.ConclusionsSCUD is a cost‐effective alternative for Lap OVE, taking into account differences in technique and user preference.

AbstractObjectivesTo compare the use of an electrosurgical device with traditional cold instruments (scalpel and scissors) for midline celiotomy incision.Study designProspective randomized controlled clinical trial.Sample population: One hundred and twenty client‐owned dogs undergoing abdominal surgery.MethodsDogs were prospectively recruited and randomized to receive electroincision or cold instrument incision. For cold incision, surgeons used basic surgical instruments including scalpel and scissors. For electroincision, surgeons only used the electrosurgical device in cutting mode. Time for the approach, blood loss, and the incision length were recorded. A blinded observer assessed pain and incision redness, swelling, and discharge at 24 and 48 hours postoperative (graded 0‐3). Owner assessment of incision healing was recorded by telephone interview.ResultsBlood loss during surgery was significantly lower for electroincision (mean 0.7, SD 1.7 mL) than cold incision (mean 3.0, SD 4.3 mL, P < .0001) with no significant difference in incision length or time for approach. Electroincision was associated with significantly less incision redness (cold median 1, range 0‐3; electroincision median 0, range 0‐2, P = .02) and less incision discharge (cold median 0.5 range 0‐3; electroincision median 0, range 0‐1, P = .006) at 24 hours postoperative. There was no significant difference in pain scores or incision healing in dogs receiving the two techniques. No incisional hernias were reported. A surgical site infection occurred in 1 dog (cold incision).ConclusionsElectroincision for a celiotomy approach in the dog reduces blood loss, and incision redness and discharge in the immediate postoperative period without affecting the occurrence of wound complications such as infection and dehiscence (including linea alba).
Molecular mechanisms of tumour invasion: regulation by calcium signals
Authors: Iamshanova Oksana , Fiorio Pla Alessandra , Prevarskaya Natalia 
Published: March 2017

AbstractIntracellular calcium (Ca2+) signals are key regulators of multiple cellular functions, both healthy and physiopathological. It is therefore unsurprising that several cancers present a strong Ca2+ homeostasis deregulation. Among the various hallmarks of cancer disease, a particular role is played by metastasis, which has a critical impact on cancer patients’ outcome. Importantly, Ca2+ signalling has been reported to control multiple aspects of the adaptive metastatic cancer cell behaviour, including epithelial–mesenchymal transition, cell migration, local invasion and induction of angiogenesis (see Abstract Figure). In this context Ca2+ signalling is considered to be a substantial intracellular tool that regulates the dynamicity and complexity of the metastatic cascade. In the present study we review the spatial and temporal organization of Ca2+ fluxes, as well as the molecular mechanisms involved in metastasis, analysing the key steps which regulate initial tumour spread.

Published: March 2017

<p>La conservación del patrimonio edificado en las ciudades se ha enfrentado a grandes retos, entre ellos la inserción del turismo, una de sus consecuencias es la relación que se establece en un mismo espacio entre los servicios urbanos y turísticos. Por ello, para asumir el nuevo rol que impone el escenario actual, los esfuerzos se concentran en crear lugares para todos en armonía con el medio natural y los promotores del desarrollo económico, social y cultural. Una de las vías es el perfeccionamiento del ordenamiento territorial para que contribuya con la conservación del patrimonio de la ciudad, por lo que se requiere de su mejora mediante la construcción de modelos. Al no existir en Cuba un estudio actualizado del balance de las funciones de los servicios urbanos y turísticos con una visión de un desarrollo integral, armónico y sostenible del centro, se impuso la necesidad de elaborar un procedimiento que tuviera como base orientar las intervenciones con el fin de contribuir al desarrollo y conservación de aquellos atractivos tangibles que hicieron que la ciudad fuera promotora del desarrollo turístico; procedimiento que posteriormente fue aplicado en la ciudad de Camagüey.
