Quinoa (Chenopodium quinoa), a herbaceous annual, has been widely cultivated in recent years because of its high nutritional value and strong tolerance to abiotic stresses. The study was conducted at two planting densities (LD, 10 plants/m2; HD, 65 plants/m2) on ameliorated coastal mudflats in Jiangsu Province, China (118° 46′ E, 32° 03′ N). The results showed soil salinity and organic matter were higher in the HD than LD treatment, and salinity of the rhizosphere soil was higher than that of the non-rhizosphere soil. Quinoa grown in HD was taller, with thicker stalks and lower yields per plant, but higher yield per unit area. Amplicon sequencing showed that Proteobacteria, Bacteroidota and Acidobacteria were the dominant bacterial phyla. Regarding the rhizosphere soil, the Shannon index was higher in the HD than LD, and Proteobacteria and Bacteroidota were more abundant in the HD treatment. Fifty-one differential metabolites were identified by metabolomic assays, belonging to 14 annotated metabolic pathways. S-adenosylmethionine was the most abundant and up-regulated metabolite (fold change >1.67), and was more abundant in the roots from the LD than HD treatment. Docosahexaenoic acid was more abundant in the HD than LD treatment, and was down-regulated metabolite. In conclusion, planting density was an important factor affecting quinoa yield; compared with unplanted soil, planting quinoa at low density increased the content of the important metabolite S-adenosylmethionine in the root system of quinoa, and high density cultivation of quinoa increased soil salinity and microbial abundance and diversity.

Large osteochondroma arising from chest wall and sternum is uncommon and presentation with airway compression is further uncommon. Here we present a case of large chest wall osteochondroma as a part of Hereditary multiple exostoses in a 9 years old boy presented with a history of stridor and shortness of breath. The bony mass of the right chest wall was extending up to a suprasternal notch and compressing the trachea. The case was successfully managed by initial femoro-femoral cardiopulmonary bypass under local anesthesia prior to the induction of anesthesia to prevent respiratory collapse, followed by debulking surgery was done.

In Cystic Fibrosis (CF), correction of splicing defects represents an interesting therapeutic approach to restore normal CFTR function. In this study, we focused on ten common mutations/variants, 711+3A>G/C, 711+5G>A, 1863C>T, 1898+3A>G, 2789+5G>A, TG13T3, TG13T5, TG12T5 and 3120G>A that induce skipping of the corresponding CFTR exons 5, 9, 13, 16 and 18. To rescue the splicing defects we tested, in a minigene assay, a panel of modified U1 snRNAs, named Exon Specific U1s (ExSpeU1) that were engineered to bind to intronic sequences downstream of each defective exon. Using this approach, we show that all ten splicing mutations analysed are efficiently corrected by specific ExSpeU1s. Using cDNA-splicing competent minigenes, we also show that the ExspeU1-mediated splicing correction at the RNA level recovered the full-length CFTR protein for 1863C>T, 1898+3A>G, 2789+5G>A variants. In addition, detailed mutagenesis experiments performed on exon 13 led us to identify a novel intronic regulatory element involved in the ExSpeU1-mediated splicing rescue. These results provide a common strategy based on modified U1 snRNAs to correct exon skipping in a group of disease-causing CFTR mutations.

Co-infection between SARS-CoV-2 and other pathogens have become a serious threat. There are reports of fungal, bacterial and viral co-infections with SARS-COV-2. Herein, we report the unusual case of concomitant aspergillosis, mucormycosis, cytomegalovirus pneumonia and also klebsiella pneumoniae empyema as the complication of COVID-19 infection.

Phenotypic plasticity can allow animals to adapt their behaviour, such as their mating effort, to their social and sexual environment. However, this relies on the individual receiving accurate and reliable cues of the environmental conditions. This can be achieved via the receipt of multi-component cues, which may provide redundancy and robustness. Male Drosophila melanogaster detect presence of rivals via combinations of any two or more redundant cue components (sound, smell and touch) and respond by extending their subsequent mating duration, which is associated with higher reproductive success. Although alternative combinations of cues of rival presence have previously been found to elicit equivalent increases in mating duration and offspring production, their redundancy in securing success under sperm competition has not previously been tested. Here, we explicitly test this by exposing male D. melanogaster to alternative combinations of rival cues and examining reproductive success in both the presence and absence of sperm competition. The results supported previous findings of redundancy of cues in terms of behavioural responses. However, there was no evidence of reproductive benefits accrued by extending mating duration in response to rivals. The lack of identifiable fitness benefits of longer mating under these conditions, both in the presence and absence of sperm competition, contrasted with some previous results, but could be explained by: 1) damage sustained from aggressive interactions with rivals leading to reduced ability to increase ejaculate investment, 2) presence of features of the social environment, such as male and female mating status, that obscured the fitness benefits of longer mating, 3) decoupling of behavioural investment with fitness benefits.

Detecting RNA molecules within their natural environment inside intact arthropods has long been challenging, particularly in small organisms covered by a tanned and pigmented cuticle. Here, we have developed a methodology that enables high-resolution analysis of the spatial distribution of transcripts of interest without having to dissect tiny organs or tissues, thereby preserving their integrity. We have combined an in situ amplification approach based on Hybridization Chain Reaction, which enhances the signal-to-noise ratio, and a clearing approach that allows the visualization of inner organs beneath the cuticle. We have implemented this methodology for the first time in Hemiptera, mapping two salivary aphid ( Acyrthosiphon pisum) transcripts, the effector c002 and the salivary sheath protein SHP. With a multiplex approach, we could simultaneously detect different mRNAs in whole-mount pea aphid head-thorax samples and show that they were distributed in distinct secretory cells of salivary glands.

Community composition is a primary determinant of how biodiversity change influences ecosystem functioning and, therefore, the relationship between biodiversity and ecosystem functioning (BEF). We examine the consequences of community composition across six structurally realistic plant community models. We find that a positive correlation between species’ functioning in monoculture vs. their dominance in mixture with regards to a specific function (the “function-dominance correlation”) generates a positive relationship between realized diversity and ecosystem functioning across species richness treatments. However, because realised diversity declines when few species dominate, a positive function-dominance correlation generates a negative relationship between realized diversity and ecosystem functioning within species richness treatments. Removing seed inflow strengthens the link between the function-dominance correlation and BEF relationships across species richness treatments but weakens it within them. These results suggest that changes in species’ identities in a local species pool may more strongly affect ecosystem functioning than changes in species richness.

Peer-review and subject-matter editing is the backbone of scientific publishing. However, early career researchers (ECRs) are given few opportunities to participate in the editorial process beyond reviewing articles. Thus, a disconnect exists: science needs high-quality editorial talent to conduct, oversee, and improve the publishing process, yet we dedicate few resources to building editorial talent nor giving ECRs formal opportunities to influence the publishing landscape from within. Here, we describe a “two-way” fellowship model that gives ECRs a “seat” at the editorial table of a field-leading journal. We describe both the necessary framework and benefits that can stem from editorial fellowships for ECRs, editors, journals, and the scientific community.

The use of pulsed dc-sputtering sources for reactive magnetron sputtering with oxygen offers a possibility to suppress the negative effects of target poisoning (such as arcing). This results in a wide process range for the selection of a desired operating point. The control of target poisoning plays a major role in maintaining constant coating properties and affects the stoichiometry of the reactive coating, as well as the coating rate and the economic impact of the coating process. In a hysteresis, the target poisoning during the reactive sputtering of titanium under oxygen addition proceeds nonlinearly. Without the use of a suitable target poisoning control technique, the sputtering process can abruptly change to an unstable state. As a result, variations of stoichiometry can occur during the deposition process. A proven method for maintaining a stable reactive sputtering process is the control of oxygen flow with the input variable target voltage. By determining the typical oxygen hysteresis at constant target power and constant argon flow, an operating point for the control loop is derived. The desired target voltage then serves as the input variable for the control loop of the target poisoning. The controlling technique for target poisoning is a basic requirement for the production of the photolytic active anatase phase of titanium dioxide (TiO2) using reactive magnetron sputtering. The photocatalytic equipment of surfaces with a titanium dioxide coating in the anatase phase can be realized with the reactive pulsed dc magnetron sputter ion plating process (DC-MSIP). The pulsed DC-MSIP process facilitates coating a variety of surfaces at temperatures below 200 °C in an environmentally friendly manner.

This editorial discusses the report titled “Cardiac Resynchronization Therapy Response in Cardiac Sarcoidosis” by Shabtaie et al.

1. Restoration ecology has historically focused on reconstructing communities of highly visible taxa whilst less visible taxa, such as invertebrates and microbes, are ignored. This is problematic as invertebrates and microbes make up the vast bulk of biodiversity and drive many key ecosystem processes, yet they are rarely actively reintroduced following restoration, potentially limiting ecosystem function and biodiversity in these areas. 2. In this review, we discuss the current (limited) incorporation of invertebrates and microbes in restoration and rewilding projects. We argue that these groups should be actively rewilded during restoration to improve biodiversity and ecosystem function outcomes and highlight how they can be used to greater effect in the future. For example, invertebrates and microbes are easily manipulated, meaning whole communities can potentially be rewilded through habitat transplants in a practice that we refer to as “whole-of-community” rewilding. 3. We provide a framework for whole-of-community rewilding and describe empirical case studies as practical applications of this under-researched restoration tool that land managers can use to improve restoration outcomes. 4. We hope this new perspective on whole-of-community restoration will promote applied research into restoration that incorporates all biota, irrespective of size, whilst also enabling a better understanding of fundamental ecological theory, such as colonisation- competition trade-offs. This may be a necessary consideration as invertebrates that are important in providing ecosystem services are declining globally; targeting invertebrate communities during restoration may be crucial in stemming this decline.

Dear Editor,We read with interest the published article by Ikeda et al. [1], they performed thoracic endovascular aortic repair (TEVAR) in a patient with Marfan syndrome (MFS) for acute complicated type B aortic dissection (TBAD) during COVID-19 pandemic.The evidence around TEVAR for MFS is scarce and open repair remains the gold treatment[2]. During the COVID-19 pandemic, many patients are either being denied treatment or given inferior options on the basis of age, comorbidities and risk of COVID pneumonia; however, the guidelines for aortic intervention in the United Kingdom have remained largely unchanged from pre-COVID-19 era [3]. Our questions to the authors relate to whether their solution was an unnecessary compromise. There is no clear indication defined in their case as a cold leg doesn’t necessary means an ischaemic limb. The TEVAR procedure performed aiming to minimise hospital stay, yet this approach may have put the patient at higher risk of developing paraplegia and visceral organ malperfusion, while compromising her long-term care.There is need to clarify if she had risk factors that prone her to a higher risk acquiring severe COVID-19 which necessitated deviating from the traditional open surgery recommended for MFS patients with TBAD [2]. The authors did not report on renal function, evidence of bowel malperfusion or whether there was resistant hypertension that needed immediate intervention. If the need to expediate intervention was the fear of limb ischaemia, is it conceivable a femoro-femoral bypass could have saved the limb and definitive open surgery on her aorta could have been performed at a later stage, especially since she was haemodynamically stable.Moreover, as Marfan-diseased aortas are prone to further dilatation, we believe their justification for opting for endovascular repair should also have been more balanced, exploring the know high rate of long-term TEVAR-associated complications in MFS patients including endoleaks, retrograde dissection, stent-graft-induced new entry tears, surgical conversions and reintervention. There is also need for imaging follow-up to assess the success of TEVAR and early detection of aforementioned complications.

Objectives: There is no standardized and up-to-date education model for urology residents in our country. We aimed to describe our National E learning education model for urology residents. Methodology: The ERTP working group; consisting of urologists was established by Society of Urological Surgery to create E-learning model and curriculum at April 2018. Learning objectives were set up in order to determine and standardize the contents of the presentations. In accordance with the Bloom Taxonomy, 834 learning objectives were created for a total of 90 lectures (18 lectures for each PGY year). Totally 90 videos were shoot by specialized instructors and webcasts were prepared. Webcasts were posted at uropedia.com.tr, which is the web library of Society of Urological Surgery. Satisfaction of residents and instructors was evaluated with feedbacks. An assessment of knowledge was measured with multiple-choice exam. Results: A total of 43 centers and 250 urology residents were included in ERTP during the academic year 2018/2019. There were 93/38/43/34/25 urology residents at 1st/2nd/3rd/4th and 5th year of residency, respectively. Majority of the residents (99.1%) completed the ERTP. The overall satisfaction rate of residents and instructors were 4,29 and 4,67(min:1 so bad, max:5 so good). An assessment exam was performed to urology residents at the end of the ERTP and the mean score was calculated as 57.99 points (min:20, max:82). Conclusion: Due to the Covid-19 pandemic, most of the educational programs had to move online platforms. We used this reliable and easily accessible e-learning platform for standardization of training in urology on national basis. We aim to share this model with international residency training programs.

Recently, nanostructure perovskite oxides such as LaMO3 (M=Co, Ni, Fe, …) received attention in academic researches due to its catalytic properties. In this research, the LaCoO3 perovskite nanoparticles have been synthesized by single-step route via the sol-gel auto-combustion method. The precursors used in this method were lanthanum nitrate and cobalt nitrate, as metals sources dissolved in distilled water and also using PVP as a surfactant, Urea and glycine as an oxidizer. The sol formed at stirring stage at 60 °C continued by gelation through the water evaporation at 90 °C and then auto-combustion occurred. Product of combustion step was washed and centrifuged three times and later calcined at 600 °C for 2 h. As synthesized nanoparticles are characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), and particle size analyzer (PSA). The characterization results proved the synthesis of nanoparticles below 100 nm with perovskite structure in narrow size distribution by using this method. The purity and size of nanoparticles vary depending on the fuel and fuel to oxidizer ratio.

Mollisols are of major importance for food security worldwide but are increasingly degraded by soil erosion. Mollisols in Northeast China have been converted into agricultural use only since the nineteenth century, but gullies are widely distributed. Gully erosion history, rates and causes in this region remained unclear. We chose a study area with landforms and land-use history typical for the central Mollisol region of Northeast China to estimate the initiation years and rates of gully erosion from 1968 to 2018 by using aerial and satellite imageries. The outlet fan deposits of a large gully system were dated by Caesium-137 (137Cs) and artefacts. Local farmers were interviewed to verify the results. Gully volumes were measured by structure-from-motion technique using photos taken from an unmanned aerial vehicle. Our results showed that gully systems had already appeared on the steep slopes and along unpaved roads in 1968. They had become larger and more complex in 2018 by upslope retreat of the main gullies and side gully formation. Gully incision started in the 1950s and 1960s, when the original grassland and forest were completely converted into arable land. From 1968 to 2018, the gully density increased from 1.2 to 2.3 km km-2 and the gully heads retreated at speeds from 1.5 to 2.5 m yr-1. The soil loss from gully erosion ranged from 25.7 to 44.7 Mg yr-1 ha-1. These data demonstrate the severity of gully erosion in the Mollisol region of Northeast China and underline the importance of appropriate countermeasures.

Pyroptosis, is a specialized form of inflammatory cell death which aids the defensive response against invading pathogens. Its tight regulation is lost during infection by the severe acute respiratory coronavirus 2 (SARS-CoV-2) and thus uncontrolled pyroptosis disrupts the immune system and the integrity of organs defining the critical conditions in patients with high viral load. Molecular pathways engaged downstream to the formation and stabilization of the inflammasome -required to execute the process- have been uncovered and drugs are available for their regulation. On the contrary, pharmacological inferring of the upstream events -which are critical to sense and interpret the initial damage by the pathogen- is far from being elucidated. This limits our capacity to identify early markers and targets to ameliorate SARS-CoV-2 linked pyroptosis. Here we aim to raise attention on mitochondria and pathways leading to its dysfunction with the goal to inform early steps of inflammasome and devise tools to interpret and counteract diseases by the SARS-CoV-2.

Background The use of thoracic endovascular aortic repair (TEVAR) for the management of uncomplicated type B aortic dissection (un-TBAD) remains controversial. There is a lack of consensus over whether pre-emptive TEVAR should be carried out in patients with un-TBAD at risk of progression to complicated TBAD. We present a review of current evidence and seek to suggest criteria where endovascular intervention in un-TBAD may prove beneficial relative to pharmacotherapy alone. Methods and Materials PubMed and Cochrane databases were searched using terms including: type B aortic dissection, risk factors, medical therapy, TEVAR, false lumen expansion, and mortality. Papers were selected based on title and abstract. Results Optimal medical therapy remains the mainstay treatment for patients with un-TBAD, however patients with un-TBAD present with varying degrees of disease progression risk. Factors such as age, aortic morphology, history of connective tissue disorders, false lumen thrombosis, and aortic branch involvement may potentiate progression from un-TBAD to complicated TBAD. Short- and long-term outcomes associated with TEVAR for TBAD remain promising. Conclusion Pre-emptive TEVAR may be beneficial in patients with un-TBAD presenting with the above factors, however further prospective research into the optimal timing for TEVAR in un-TBAD is required.

Knowledge Graphs have been fast emerging as the {\em de facto} standard to model and explore knowledge in weakly structured data. Large corpora of documents constitute a source of weakly structured data of particular interest for both the academic as well as the industrial world. Key examples include scientific publications, technical reports, manuals, patents, regulations, etc. Such corpora embed many facts that are elementary to critical decision making or enabling new discoveries. In this paper, we present a scalable cloud platform to create and serve Knowledge Graphs, which we named \textit{Corpus Processing Service}. Its purpose is to process large document corpora, extract the content and embedded facts, and ultimately represent these in a consistent knowledge graph that can be intuitively queried. To accomplish this, we use state-of-the-art natural language understanding models to extract entities and relationships from documents converted with our previously presented CCS platform. This pipeline is complemented with a newly developed graph engine which ensures extremely performant graph queries and provides powerful graph analytics capabilities. Both components are tightly integrated and can be easily consumed through REST APIs. Additionally, we provide user-interfaces to control the data ingestion flow and formulate queries using a visual programming approach. The CPS platform is designed as a modular microservice system operating on Kubernetes clusters. Finally, we validate the quality of queries on our truly end-to-end knowledge pipeline in a real-world application in the oil and gas industry. To date, the capabilities of CPS are successfully leveraged in more than 5 client engagements.
