Published: November 2017

AbstractChinese consumers prefer to consume fish that have only in the vigorously live state. Therefore, it is not easily and imprecisely for aquatic enterprises to implement effective aquatic survival prediction and maintain a reasonable high survival rate after live transportation. For another, traditional live fish transportation is in water, and it is cost‐prohibitive and managing‐complex. Nevertheless, waterless live fish delivery under cooling condition is considered as an alternative and promising strategy with less complexity and large traffic volume. Chinese Sturgeon had been taken as experimental subjects in our study and worked out the correlation between temperature range and survival rate with minimum stress changes. Moreover, dynamic probing for fish stress changes in term of glucose‐sensor that is a significant survey to get optimum shipment temperature and design survival computing model by over 30 hr delivering experiments, and use the deviation from reasonable temperature variation to accurately predict the final survival result. The result clearly shows the forecasting accuracy of the system is quite enough to content the requirements of aquatic enterprises. As a result, it is meaningful to provide a new management approach to improve transportation efficiency, reduce the losses, and also ensure consumers to eat high‐quality of live aquatic products.Practical applicationsConsumers have recently become more favorite with the live Chinese Sturgeon with respect to its good flavor and nutrition. In the process of live fish delivering, the logistic temperature controlling with minimum stress is the advisable way to improve the survival result for waterless live Sturgeon storage and transportation. Moreover, to fit the optimum temperature series of the real changes, the final survival rate can be estimated in a relatively high level that is quite enough to satisfy the requirement of waterless live aquatic logistics under controlled temperature range 1–3 °C.

AbstractBackgroundChromosome 22q11.2 microdeletion syndrome (22q11.2DS) is a genetic syndrome characterised by a unique cognitive profile. Individuals with the syndrome present several non‐verbal deficits, including visual memory impairments and atypical exploration of visual information. In this study, we seek to understand how visual attention may contribute to memory difficulties in 22q11.2DS by tracking eye movements during the encoding phase of a visual short‐term memory task.MethodEye movements were recorded during a computerised version of the multiple‐choice Benton Visual Retention Test, which consisted of exploring and then recognising complex visual stimuli. Seventy‐four participants affected by 22q11.2DS were compared with 70 typically developing participants.ResultsParticipants with 22q11.2DS performed less well than healthy controls on the task and spent more time and fixations on the principal (larger central) figures and less time and fixations on the smaller peripheral figures within the stimuli.ConclusionsThis study is the first to investigate visual attention in 22q11.2DS during a memory task. The results delineate impaired processes during encoding that affect visual memory performance. The findings may be especially useful for informing interventions intended to boost visual learning in patients with 22q11.2DS.
Verbal short‐term memory shows a specific association with receptive but not productive vocabulary measures in Down syndrome

Published: November 2017

AbstractBackgroundVerbal short‐term memory (STM) capacity has been considered to support vocabulary learning in typical children and adults, but evidence for this link is inconsistent for studies in individuals with Down syndrome (DS). The aim of this study was explore the role of processing demands on the association between verbal STM and vocabulary measures in DS, by comparing receptive vocabulary measures with high STM processing demands to productive vocabulary measures with low STM processing demands.MethodForty‐seven adults with Down syndrome were administered receptive vocabulary and productive vocabulary tasks, as well as measures of verbal STM abilities and intellectual efficiency.ResultsBayesian regression analyses showed that verbal STM abilities were strongly and specifically associated with receptive vocabulary measures but not productive lexical abilities after controlling for intellectual efficiency, and this is despite the fact that vocabulary abilities as measured by receptive and productive vocabulary tasks were closely associated.ConclusionsIn Down syndrome, verbal STM abilities may be predictive of specific task demands associated with receptive vocabulary tasks rather than of vocabulary development per se.

SummaryBackground/purposeNatural ingredients have been always an interesting approach to prolong youthful appearance of skin. One of the natural compounds is Kombucha tea (KT), which has been mainly used as an energy drink in Asian countries for a long time. Previous reports indicated that it has pharmaceutical and favorable wound repairing effects. The beneficial properties of KT are thought to be mainly due to the presence of fermentation products such as flavonoids and other polyphenols with inhibition of hydrolytic and oxidative enzymes and anti‐inflammatory effects. These properties prompted us to study the anti‐aging potential of KT and investigate its effective fraction in aged mice,MethodsKombucha tea was fractionated into chloroform, butanol, and ethyl acetate, and flavonoid content was determined. Young and old mice were used as control. KT ethyl acetate fraction (KEAf), which had the highest flavonoid content, was intradermally administered to old mice.ResultsAdministration of KEAf significantly increased the collagen content, NAD+/NADH level, and concomitantly improved skin connective tissue abnormalities in the aged skin. No sensitivity or irritation was observed.ConclusionThis finding suggested that KEAf can be a suitable candidate as a cosmetic product to improve aging‐related skin abnormalities and regeneration of aged skin.

AbstractThe hormone jasmonate (JA) signalling pathway is involved in diverse developmental processes in plants. COI1 is a key regulator in JA pathway. Although COI1 homologous proteins have been identified in a variety of crops, their regulatory mechanisms in wheat defence responses remain unknown. Here, we cloned COI1 from disease resistant wheat Brock, designated TaCOI1. TaCOI1 cDNA was 1988‐bp long, with an ORF encoding 593 deduced amino acids. The phylogenetic tree showed that TaCOI1 was clustered in the same clade of monocotyledons. The predicted protein possesses an F‐box domain, several LRRs and a conserved AMN1 domain. Its transcription was induced in the compatible and incompatible wheat by Blumeria graminis f. sp. tritici (Bgt) fungus, with differences observed in response time. Expression pattern analysis in the susceptible wheat variety Jing411 revealed that TaCOI1 was up‐regulated after Bgt inoculation at 12‐hour postinoculation (hpi). While, in Brock its transcription was rapidly induced and reached a first peak at 2 hpi. These results suggest that TaCOI1 may be involved in the early response to powdery mildew. The expression of TaCOI1 was decreased by virus‐induced gene silencing. The rate of successful penetration by Bgt was higher in all TaCOI1‐silenced Brock, while the percentage of macrocephalic appressoria and resistance reactions was lower than control. These results suggest that silencing of the TaCOI1 gene increased Brock susceptibility to infection. Together, these findings indicate that the TaCOI1 gene could be involved in the early defence response against wheat powdery mildew and may play an important role in wheat–Bgt interactions.
Toxic stress and child refugees
Authors: Murray John S. 
Published: November 2017

AbstractThe purpose of this article was to describe the phenomenon of toxic stress and its impact on the physical and mental health of child refugees. Almost two decades ago, researchers found that recurring adverse childhood events (ACEs; e.g., physical, psychological, and sexual abuse, neglect, and household dysfunction such as substance abuse, mental illness, and criminal behavior) were associated with a significant increase in serious illnesses during adulthood. Illnesses include heart, lung, and liver disease, cancer, and bone fractures. The scientists reported that experiencing four or more ACEs during childhood significantly increases the risk for toxic stress. Toxic stress is defined as the exposure to extreme, frequent, and persistent adverse events without the presence of a supportive caretaker. There is a paucity of literature related to toxic stress and child refugees. However, it has been clearly established that the prolonged brutal and traumatizing war in Syria is having a profound impact on the physical and mental health of child refugees at a distressing rate. Prevention of toxic stress should be a primary goal of all pediatric healthcare professionals working with child refugees. While this seems daunting given the population, and the seemingly insurmountable stressors they experience, some basic interventions should be considered. Providing basic anticipatory guidance to parents and caregivers of child refugees, to encourage positive parenting and strengthening support networks, will be highly effective in developing the requisite buffers that mitigate the effects of stress and avoid toxic stress. Efforts should also be focused on addressing caregiver stress and improving their ability to provide safe, reliable, and nurturing care that will help to mitigate any stress response experienced by a child.Practice ImplicationsIt is critical that greater awareness be placed on the effects of toxic stress on child refugees who are exposed to significant adverse events early in life.

AbstractSemitendinosus (ST) muscle steaks were grouped according to three locations (proximal, middle, and distal end), grilled to endpoint temperature of 71C or cooked for 20, 30, 40, 50, or 60 s in a microwave oven (Mw). The location did not affect (p > .05) the cooking loss (CL) or shear force (SF) values. The CL increased (p < .05) with longer microwave cooking times, but only the Mw40 samples did not differ (p > .05) from the grill samples. None of the microwaves' SF values were different (p > .05) from the grill values, with treatments Mw30 to Mw50 showing moderate repeatability (R = 0.51–0.60) and Mw30 and Mw60 showing higher correlations (r > .71) with grill values. Cooking beef strips with a microwave is a potential method for tenderness evaluation, but requires additional study to evaluate and optimize this application in different muscles and for comparison to sensorial data.Practical applicationsThe work was intended to evaluate the possibility of using a microwave oven for cooking meat to be used in objective measurement protocols for meat tenderness and to optimize the conditions for this purpose. The use of a standardized microwave procedure allows a dramatic reduction in analysis time and may reduce error variance due to nonuniform cooking procedures.

Published: November 2017

AbstractQuestionsFire and livestock grazing are regarded as current threats to biodiversity and landscape integrity in northern Australia, yet it remains unclear what biodiversity losses and habitat changes occurred in the 19–20th centuries as livestock and novel fire regimes were introduced by Europeans. What baseline is appropriate for assessing current and future environmental change?LocationAustralia's Kimberley region is internationally recognized for its unique biodiversity and cultural heritage. The region is home to some of the world's most extensive and ancient rock art galleries, created by Aboriginal peoples since their arrival on the continent 65,000 years ago. The Kimberley is considered one of Australia's most intact landscapes and its assumed natural vegetation has been mapped in detail.MethodsInterpretations are based on a continuous sediment record obtained from a waterhole on the Mitchell River floodplain. Sediments were analysed for geochemical and palynological proxies of environmental change and dated using 210Pb and 14C techniques.ResultsWe show that the present‐day vegetation in and around the waterhole is very different to its pre‐European counterpart. Pre‐European riparian vegetation was dominated by Antidesma ghaesembilla and Banksia dentata, both of which declined rapidly at the beginning of the 20th century. Soon after, savanna density around the site declined and grasses became more prevalent. These vegetation shifts were accompanied by geochemical and biological evidence for increased grazing, local burning, erosion and eutrophication.ConclusionsWe suggest that the Kimberley region's vegetation, while maintaining a ‘natural’ appearance, has been altered dramatically during the last 100 years through grazing and fire regime changes. Landscape management should consider whether the current (impacted) vegetation is a desirable or realistic baseline target for biodiversity conservation.
A Review of Genetic Advances Related to Sex Control and Manipulation in Tilapia

Published: November 2017

AbstractTilapias are the second most farmed fish worldwide. Production of tilapia has quadrupled over the past decade because of the ease with which they are cultured, their marketability, and the stability of market prices. Continued increases in tilapia production must be based on sustainable practices. Excessive reproduction during growout has been a major problem in tilapia aquaculture and has been addressed by culturing monosex (all‐male) populations. The best way to obtain monosex populations is through control of sexual development. To produce genetically male tilapia, researchers can arrange matings using sex‐specific DNA markers, create hybrids between tilapia strains with different sex determination loci, or they can alter the innate genetic traits of a species. Improved varieties have, in many cases, facilitated the development of the aquaculture industry by lowering costs and increasing both quality and yield. In this review, we focus on the application of marker‐assisted breeding, cross‐breeding, and genetic modification technologies to control sexual development in tilapia.

Published: November 2017

AbstractIn coastal marine ecosystems, spatial patterns of larval fish assemblages (LFAs) tend to exhibit geographic stability because of relatively stable spawning site selection and predictable oceanographic phenomena such as eddies. To evaluate the relationship between spatial heterogeneity and temporal variability of LFAs, we conducted a high spatiotemporal resolution ichthyoplankton survey from April to July in 2013 in the shallow waters (<20 m) of Haizhou Bay, China. Our analysis indicated three distinct assemblages, which were stable geographically but exhibited a gradual and directional change of species composition and abundance over our study period. Sea surface temperature was the most important environmental co‐variate for determining temporal variability of LFAs, likely owing to temperature effects of species composition and spawning period selection of adult fish, along with known temperature‐dependent survival rates of larval fish. Study of LFA spatiotemporal dynamics is essential for improved understanding of adult fish spawning behavior, and has potential to inform design and implementation of conservation and management measures (e.g. marine protected areas) in coastal systems.

AbstractOne important, almost ubiquitous, tool for understanding the surfaces of solid bodies throughout the solar system is the study of impact craters. While measuring a distribution of crater diameters and locations is an important tool for a wide variety of studies, so too is measuring a crater's “depth.” Depth can inform numerous studies including the strength of a surface and modification rates in the local environment. There is, however, no standard data set, definition, or technique to perform this data‐gathering task, and the abundance of different definitions of “depth” and methods for estimating that quantity can lead to misunderstandings in and of the literature. In this review, we describe a wide variety of data sets and methods to analyze those data sets that have been, are currently, or could be used to derive different types of crater depth measurements. We also recommend certain nomenclature in doing so to help standardize practice in the field. We present a review section of all crater depths that have been published on different solar system bodies which shows how the field has evolved through time and how some common assumptions might not be wholly accurate. We conclude with several recommendations for researchers which could help different data sets to be more easily understood and compared.
The impact of mating systems and dispersal on fine‐scale genetic structure at maternally, paternally and biparentally inherited markers
Authors: Shaw Robyn E. , Banks Sam C. , Peakall Rod 
Published: November 2017

AbstractFor decades, studies have focused on how dispersal and mating systems influence genetic structure across populations or social groups. However, we still lack a thorough understanding of how these processes and their interaction shape spatial genetic patterns over a finer scale (tens—hundreds of metres). Using uniparentally inherited markers may help answer these questions, yet their potential has not been fully explored. Here, we use individual‐level simulations to investigate the effects of dispersal and mating system on fine‐scale genetic structure at autosomal, mitochondrial and Y chromosome markers. Using genetic spatial autocorrelation analysis, we found that dispersal was the major driver of fine‐scale genetic structure across maternally, paternally and biparentally inherited markers. However, when dispersal was restricted (mean distance = 100 m), variation in mating behaviour created strong differences in the comparative level of structure detected at maternally and paternally inherited markers. Promiscuity reduced spatial genetic structure at Y chromosome loci (relative to monogamy), whereas structure increased under polygyny. In contrast, mitochondrial and autosomal markers were robust to differences in the specific mating system, although genetic structure increased across all markers when reproductive success was skewed towards fewer individuals. Comparing males and females at Y chromosome vs. mitochondrial markers, respectively, revealed that some mating systems can generate similar patterns to those expected under sex‐biased dispersal. This demonstrates the need for caution when inferring ecological and behavioural processes from genetic results. Comparing patterns between the sexes, across a range of marker types, may help us tease apart the processes shaping fine‐scale genetic structure.
Nurses’ experiences of unprofessional behaviors in the emergency department: A qualitative study

Published: November 2017

AbstractThe nursing profession is focused on serving others and has high expectations that each member behaves professionally and ethically, as articulated in nursing codes of practice and conduct. Where these are not upheld, inappropriate and unprofessional workplace behaviors follow. Regrettably, unprofessional behavior is neither new nor constrained to the nursing profession, but is known to negatively impact staff and workplace relationships, and importantly, patient safety and care. The aim of this qualitative study was to explore Iranian nurses’ experiences of professional communication between colleagues in the emergency department. Fifteen individual interviews were conducted. The overarching theme to emerge from the data was workplace communication, supported by two subthemes: unprofessional behavior and stressors in the workplace. Individually and collectively, these subthemes demonstrated staff attitudes and behaviors that are inconsistent with expectations of professional behavior and practice. Management proactively addressing unprofessional workplace behaviors is fundamental to establishing and maintaining positive workplace environments and supporting safe, quality patient care.
Toward a comprehensive, theoretical model of compassion fatigue: An integrative literature review
Authors: Coetzee Siedine K. , Laschinger Heather K.S. 
Published: November 2017

AbstractThis study was an integrative literature review in relation to compassion fatigue models, appraising these models, and developing a comprehensive theoretical model of compassion fatigue. A systematic search on PubMed, EbscoHost (Academic Search Premier, E‐Journals, Medline, PsycINFO, Health Source Nursing/Academic Edition, CINAHL, MasterFILE Premier and Health Source Consumer Edition), gray literature, and manual searches of included reference lists was conducted in 2016. The studies (n = 11) were analyzed, and the strengths and limitations of the compassion fatigue models identified. We further built on these models through the application of the conservation of resources theory and the social neuroscience of empathy. The compassion fatigue model shows that it is not empathy that puts nurses at risk of developing compassion fatigue, but rather a lack of resources, inadequate positive feedback, and the nurse’s response to personal distress. By acting on these three aspects, the risk of developing compassion fatigue can be addressed, which could improve the retention of a compassionate and committed nurse workforce.
