Abstract
Background: Phosphate is an essential plant macronutrient required to achieve maximum crop yield. Roots are able to uptake soil phosphate from the immediate root area, thus creating a nutrient depletion zone. Many plants are able to exploit phosphate from beyond this root nutrient depletion zone through symbiotic association with Arbuscular Mycorrhizal Fungi (AMF). Here we characterise the relationship between root architecture, AMF association and low phosphate tolerance in strawberries. The contrasting root architecture in the parental strawberry cultivars ‘Redgauntlet’ and ‘Hapil’ was studied through a mapping population of 168 progeny. Low phosphate tolerance and AMF association was quantified for each genotype to allow assessment of the phenotypic and genotypic relationships between traits. Results: A “phosphate scavenging” root phenotype where individuals exhibit a high proportion of surface lateral roots was associated with a reduction in root system size across genotypes. A genetic correlation between “root system size” traits was observed with a network of pleiotropic QTL were found to represent five “root system size” traits. By contrast, average root diameter and the distribution of roots appeared to be under two discrete methods of genetic control. A total of 18 QTL were associated with plant traits, 4 of which were associated with solidity that explained 46 % of the observed variation. Investigations into the relationship between AMF association and root architecture found that a higher root density was associated with greater AMF colonisation across genotypes. However, no phenotypic correlation or genotypic association was found between low phosphate tolerance and the propensity for AMF association, nor root architectural traits when plants are grown under optimal nutrient conditions.Conclusions: Understanding the genetic relationships underpinning phosphate capture can inform the breeding of strawberry varieties with better nutrient use efficiency. Solid root systems were associated with greater AMF colonisation. However, low P-tolerance was not phenotypically or genotypically associated with root architecture traits in strawberry plants. Furthermore, a trade-off was observed between root system size and root architecture type, highlighting the energetic costs associated with a “phosphate scavenging” root architecture.

Abstract
Background

With an increase in the elderly population, the occurrence of hip fractures, femoral neck fractures, and intertrochanteric fractures (ITFs) is also increasing. It is important to establish effective perioperative methods that would help reduce the morbidity and mortality rates associated with ITFs. The purpose of this study was to determine the effects of ITFs according to the AO classification for perioperative hemoglobin drop.

Methods

Seventy-six patients with ITFs classified as AO 31-A1 or A2 and fixated with intramedullary nails participated in this retrospective cohort study. Medical records of these patients were retrospectively reviewed from September 2016 to August 2018. The perioperative hemoglobin drop was chosen as the main outcome measure and calculated as the difference between pre- and postoperative hemoglobin levels. Multivariate linear regression analysis was performed and included the following variables: AO classification (A1.1-A2.1 [stable] vs. A2.2-A2.3 [unstable]), time interval between injury and surgery, age, body mass index, and the use of anticoagulants.

Results

Among the 76 patients who met the inclusion criteria, a significantly higher hemoglobin drop was observed in the AO 31 A2.2-A2.3 (unstable) group than in the AO 31 A1.1-A2.1 (stable) group (p = 0.04). The multivariate analysis also showed a greater hemoglobin drop in the unstable group (p < 0.05).

Conclusions

Patients with unstable ITFs exhibited a greater hemoglobin drop and a hidden blood loss was suspected around the fracture site. We believe that this should be taken into consideration when presurgical blood transfusion is being planned for patients with unstable ITFs, to reduce associated postoperative complications, especially in patients with severe anemia or high risk of mortality.

Abstract
Background Hepatocellular carcinoma (HCC) is the fifth most common malignancy and the third leading cause of cancer mortality worldwide. The development of new anticancer agents targeting different pathways is imperative to improve the advanced HCC. The aberrant metabolism and aggressive growth of cancer cells can render them particularly susceptible to proteasome inhibition, as first demonstrated by the success of bortezomib treatment for multiple myeloma. However, resistance does emerge and this 20S proteasome inhibitor has not proven active against HCC. The bis-benzylidine piperidone RA190 represents a novel class of proteasome inhibitor that covalently binds to cysteine 88 of RPN13, a ubiquitin receptor subunit of the proteasome’s 19S regulatory particle. RA190 treatment inhibits proteasome function, causing rapid accumulation of polyubiquitinated proteins. Methods Human HCC cell lines were treated by RA190 in vitro in different concentration and time frame. We checked the killing effect and the possible mechanisms that lead the tumor apoptosis. We also performed the orthotopic HCC animal model to show the RA190 had significant killing effect in vivo . Results We showed RA190 is also toxic to HCC cells by triggering the rapid build-up of polyubiquitinated proteins, resulting in endoplasmic reticulum stress and the induction of cell death via apoptosis. Considerable evidence suggests that nuclear factor κB (NF-κB) signal is essential for promoting inflammation-associated cancer. Here, we showed that RA190 inhibited the NF-κB pathway in HCC by preventing the degradation of IκBα via the proteasome. Treatment of mice bearing an orthotopic HCC model with RA190 significantly reduced tumor growth. We therefore explored combining RA190 with a tyrosine kinase inhibitor currently used to the treat HCC, Sorafenib. Conclusions RA190 and Sorafenib exhibited synergetic killing of HCC cells in vitro , suggesting further exploration of such a combination treatment of HCC is warranted.

Published: March 2020

Abstract
Background
Indigenous Australians suffer from higher rates of oral disease and have more untreated dental problems and tooth extractions than the general population. Indigenous Australians also have lower rates of accessing oral health services and are more likely to visit for a problem rather than a check-up. Multiple issues effect health service and prevention programs including: characteristics of health services such as distances to health services; existence of social and cultural barriers; available wealth and social support; and, characteristics of the individual and community including the importance given to the disease. This paper seeks to explore the perceived importance of oral health within a rural Indigenous community in Australia and the factors influencing this perception.

Methods
The study used a phenomenology research design incorporating focus group discussions and in-depth interviews. It was undertaken in partnership with communities’ Health Action Group who guided the focus, implementation and reporting of the research. A convenience sample was recruited from established community groups. Thematic analysis on the transcripts was completed.

Results
Twenty- seven community members participated in three focus groups and twelve in-depth interviews. The study found that the community gives high priority to oral health. Factors influencing the importance include: the perceived severity of symptoms of oral disease such as pain experienced due to tooth ache; lack of enabling resources such as access to finance and transport; the social impact of oral disease on individuals including impact on their personal appearance and self-esteem; and health beliefs including oral health awareness. Participants also noted that the importance given to oral health within the community competed with the occurrence of multiple health concerns and family responsibilities.

Conclusion
This paper highlights the high importance this rural Indigenous community gives to oral health. Its findings suggest that under-utilisation of oral health services is influenced by both major barriers faced in accessing oral health services; and the number and severity of competing health and social concerns within the community. The study results confirm the importance of establishing affordable, culturally appropriate, community-based oral health care services to improve the oral health of rural Indigenous communities.

Abstract
Background In the Netherlands, Aedes albopictus has been found each year since 2010 during routine exotic mosquito species surveillance at companies that import used tires. We developed habitat suitability models to investigate the potential risk of establishment and spread of this invasive species at these locations. Methods We used two methodologies: first, a species distribution model based on the maximum entropy modelling approach (MaxEnt) taking into consideration updated occurrence data of the species in Europe, and second, a spatial logic conditional model based on the temperature requirements of the species and using land surface temperature data (LST model). Results Suitability assessment obtained with the MaxEnt model at European level accurately reflect the current distribution of the species and these results also depict moderately low values in parts of the Netherlands, Belgium, Denmark, the British islands and southern parts of Scandinavia. Winter temperature was the variable that contributed most to the performance of the model (47.3%). The results of the LST model show that 1) coastal areas are suitable for overwintering of eggs, 2) large areas in the northern part of the country have a low suitability for adult survival, and 3) the entire country is suitable for successful completion of the life cycle if the species is introduced after the winter months. Results of the LST model reveal that temperatures in 2012 and 2014 did not limit the overwintering of eggs or survival of adults at the locations where the species was found. By contrast, for the years 2010, 2011 and 2013, overwintering of eggs at these locations is considered unlikely. Conclusions Results using two modelling methodologies show differences in predicted habitat suitability values. Based on the results of both models, the climatic conditions could hamper the successful overwintering of eggs of Ae. albopictus and their survival as adults in many areas of the country. However, during warm years with mild winters, many areas of the Netherlands offer climatic conditions suitable for developing populations. Regular updates of the models, using updated occurrence and climatic data, are recommended to study the areas at risk.

Abstract
Background While epidermal growth factor receptor(EGFR) tyrosine kinase inhibitors(TKIs) exert a breakthrough effect, the incidence of skin disorders as a side effect has significantly reduced patients' quality of life. Objective This study aimed to develop a treatment for inflammatory ulcers as one of the side effects of afatinib (Geotrif®), a second-generation EGFR-TKI, and established a skin disorder mouse model to investigate the protective effect of minocycline. Methods First, under inhalation anesthesia with isoflurane, the back of a male ddy mouse was shaved, and afatinib petrolatum was applied alone or in combination with minocycline to observe the state of the skin and measure transepidermal water transpiration (TEWL). Next, afatinib was administered orally to mice, and minocycline petrolatum was applied to observe whether the skin disorder was prevented and its effect on repair of the skin disorder. Results Skin injury occurred on the back of the mouse following afatinib (1 mg/g in petrolatum) application, and scab formation was observed. Application of minocycline prevented and improved the skin disorder caused by afatinib. When the minocycline-petrolatum mixture was applied to the mouse that developed the skin disorder, a significant improvement in TEWL was observed, and skin repair was observed macroscopically. Discussion These results suggest that minocycline applied both locally and orally prevents and repairs afatinib-induced skin disorders. Histological examination of skin elucidated the mechanism of the occurrence of the EGFR-TKI-related skin disorder and suggested the efficacy of minocycline topical application in clinical practice.
Estimating runtime of a job in Hadoop MapReduce
Authors: Peyravi Narges , Moeini Ali 
Published: March 2020

Abstract
Hadoop MapReduce is a framework to process vast amounts of data in the cluster of machines in a reliable and fault-tolerant manner. Since being aware of the runtime of a job is crucial to subsequent decisions of this platform and being better management, in this paper we propose a new method to estimate the runtime of a job. For this purpose, after analysis the anatomy of processing a job in Hadoop MapReduce precisely, we consider two cases: when a job runs for the first time or a job has run previously. In the first case, by considering essential and efficient parameters that higher impact on runtime we formulate each phase of the Hadoop execution pipeline and state them by mathematical expressions to calculate runtime of a job. In the second case, by referring to the profile or history of a job in the database and use a weighting system the runtime is estimated. The results show the average error rate is less than 12% in the estimation of runtime for the first run and less than 8.5% when the profile or history of the job has existed.
Cavernous malformation hemorrhage due to trans-mural pressure alterations after cerebrospinal fluid diversion: a case report
Authors: Hartley Benjamin , Birnbaum Corinne , Hoffman Caitlin E 
Published: March 2020

Abstract
Background: Cavernous malformations are rare cerebral pseudo-vascular lesions with annualized bleeding rates of 0.5 – 3% in most studies. Of the various explored risk factors for bleeding to date, only prior hemorrhage has shown significant correlation. Case Presentation: In this case, we describe a 65-year old man with a peri-ventricular atrial cavernous malformation that hemorrhaged after CSF diversion via ventriculoperitoneal shunting. Serial imaging showed that bleeding continued until the shunt was revised with a programmable valve set at maximum resistance with the addition of a gravitational unit, thereby lowering the trans-mural pressure differential across the cavernous malformation. Conclusions: Given that other vascular lesions are subject to hemorrhage from alterations in trans-mural pressure dynamics, we hypothesize that cavernous malformations are similarly affected by trans-mural pressure gradients as they are composed of primitive vascular elements. This hypothesis is corroborated by the temporal correlation of interventions, imaging, and exam findings in the present case, and suggests a potentially important risk factor for hemorrhage in CM patients that affects prognostication and management.

Published: March 2020

Abstract
Background. The Weddell Seal (Leptonychotes weddelli) represents a remarkable example of adaptation to diving among marine mammals. This species is capable of diving >900 m deep and remaining underwater for more than 60 minutes. A number of key physiological specializations have been identified, including the low levels of aerobic, lipid-based metabolism under hypoxia, significant increase in oxygen storage in blood and muscle; high blood volume and extreme cardiovascular control. These adaptations have been linked to increased abundance of key proteins, suggesting an important, yet still understudied role for gene reprogramming. In this study, we investigate the possibility that post-transcriptional gene regulation by microRNAs (miRNAs) has contributed to the adaptive evolution of diving capacities in the Weddell Seal. Results. Using small RNA data across 4 tissues (cortex, heart, muscle and plasma), in 3 biological replicates, we generate the first miRNA annotation in this species, consisting of 559 high confidence, manually curated miRNA loci. Evolutionary analyses of miRNA gain and loss highlight a high number of Weddell seal specific miRNAs. 416 miRNAs were differentially expressed (DE) among tissues, whereas 83 miRNAs were differentially expressed (DE) across all tissues between pups and adults and 188 miRNAs demonstrated developmental changes in specific tissues only. mRNA targets of these altered miRNAs identify possible protective mechanisms in individual tissues, particularly relevant to hypoxia tolerance, anti-apoptotic pathways, and nitric oxide signal transduction. Novel, lineage-specific miRNAs associated with developmental changes target genes with roles in angiogenesis and vasoregulatory signaling. Conclusions. Altogether, we provide an overview of miRNA composition and evolution in the Weddell seal, and the first insights into their possible role in the specialization to diving.

Abstract
Background Technological solutions may improve the logistics of obtaining parental consent in school-based immunisation programmes. In 2018/19 a health care organisation in London, England, piloted an electronic consent intervention in the adolescent girls’ HPV vaccination programme. We conducted a mixed-methods evaluation to examine the usability and acceptability of the intervention and assess its impact on consent form returns and HPV vaccine uptake. Methods The intervention was implemented in 14 secondary schools in seven South London boroughs. Each e-consent school was matched with a school that used standard paper consent. Matching was based on location and the proportion of students: i. with English as a second language, ii. receiving free school meals (socio-economic status proxy). Consent form return rates and HPV vaccine uptake were compared quantitatively between intervention and matched schools. Data from immunisation session observations (n=7), school feedback forms (n=14), individual and group interviews with implementers (n=8), parents and adolescents (n=12) and a focus group discussion with adolescents was analysed thematically to document user’s experiences investigate the implementation of the intervention. Results HPV vaccination uptake did not differ between e-consent and matched paper consent schools, but timely consent form return was significantly lower in the e-consent schools (73.3% (n=11) vs 91.6% (n=11), p=0.008). The transition to using the system was not straightforward, whilst schools and staff understood the potential benefits, they found it difficult to adapt to new ways of working which removed some level of control from schools. Part of the reason for lower consent form return in e-consent schools was that some parents found the intervention difficult to access and use. Adolescents highlighted the potential for e-consent interventions to by-pass their information needs. Conclusions The e-consent intervention did not improve consent form return or vaccine uptake due to challenges encountered in transitioning to a new way of working. New technologies require embedding before they become incorporated in everyday practice. The intervention is undergoing further iterative development to improve its usability, ensure schools are appropriately involved and adolescents receive tailored immunisation information. A re-evaluation once stakeholders are accustomed to e-consent may be required to understand its impact.
A Novel Highway Routing Protocol in Vehicular Ad hoc Networks

Published: March 2020

Abstract
The Vehicular Ad hoc Networks (VANETs) are an example of mobile networks which utilizes Dedicated Short Range Communication (DSRC) to establish a wireless connection between cars and their primary purpose is to provide more security and comfort for passengers. These networks utilize wireless communications and vehicular technology to collect and disseminate traffic information, and it is required to be delivered to all vehicles on the network reliably and quickly. One of the major challenges raised in VANETs is that the communication path between the source and destination nodes is disconnected due to the dynamic nature of the nodes in this network, and the reconnection process of nodes through the new path reduces the performance of network. This paper presents a highway routing protocol to overcome some of the challenges of these networks including cost, delay, packet delivery rate, and overhead. The NS2 is used for simulation and the performance of the proposed protocol is compared with the VMaSC-LTE and DBA-MAC protocols. The results of the simulation indicated that the proposed protocol performs better than the mentioned protocols.
