Published: October 2020

AbstractElectroactive microorganisms play a significant role in microbial fuel cells (MFCs). These devices, which are based on a wide microbial diversity, can convert a large array of organic matter components into sustainable and renewable energy. At present, electricity-producing microorganisms are mostly isolated from sewage, anaerobic sediments and soil, however, the sources are very limited. For a more comprehensive understanding of the electron transfer mechanism of the electricity-producing microorganisms and the interaction with the environment, it is necessary to obtain a thorough understanding of their resource distribution and discover potential resources. In this study, plant tissues were selected to isolate endophytic bacteria, and the electrochemical activity potential of those bacteria was evaluated by high-throughput screening with a WO3 nanoprobe. Twenty-six strains of endophytic bacteria were isolated from plant tissues belonging to Angelica and Sweet Potato, of which 17 strains from 6 genera had electrochemical activity, including Bacillus sp., Pleomorphomonas sp., Rahnella sp., Shinella sp., Paenibacillus sp. and Staphylococcus sp.. Moreover, the electricity-producing microorganisms in the plant tissue are enriched. Microbial community analysis by high-throughput sequence indicated that Pseudomonas and Clostridioides are the dominant genera of MFC anode inoculated with angelica tissue.Staphylococcus and Lachnoclostridium 5 are the dominant genera in MFC anode inoculated with sweet potato tissue. And the most representative Gram-positive strain Staphylococcus succinus subsp. succinus H6 and plant tissue-inoculated MFC were further analyzed for electrochemical activity. After nearly 1500 h of voltage monitoring and cyclic voltammetry analysis, the results showed that a strain numbered H6 and plant tissue-inoculated MFC had a good electrogenerating activity.ImportanceSome biological characteristics of microorganisms are inextricably linked to their living environment. For plant endophytes, some of their biological characteristics have a profound impact on the host. The discovery of the production of electrobacteria in plants helps us to understand the interaction between microorganisms and plants more deeply. For example, there may be intercellular electron transfer between the internally producing bacteria and nitrogen-fixing bacteria to improve the efficiency of nitrogen fixation. In addition, there may be a connection between the weak electrical signal of the plant and the the endophytic electricity-producing microorganismsThe discovery of electricity-producing bacteria in plants also brings a more comprehensive understanding of the distribution of electricity-producing microbial resources and the mechanism of origin.

AbstractDilated cardiomyopathy with ataxia (DCMA) syndrome is a rare mitochondrial disorder caused by mutations in the poorly understoodDNAJC19gene. The clinical presentation of DCMA is very diverse with symptoms ranging from mild cardiac dysfunction to intractable heart failure leading to death in early childhood. Although several lines of evidence indicate that DCMA symptoms are linked to mitochondrial function, the molecular underpinnings of this disease are unclear and there is no way to predict which patients are at risk for developing life-threatening symptoms. To address this we developed a metabolic flux assay for assessing the metabolic function of mitochondria in dermal fibroblasts derived from DCMA patients. Using this approach we discovered that fibroblasts from patients with DCMA showed elevated glutamine uptake, increased glutamate and ammonium secretion, and elevated lactate production when compared to controls. Moreover, the magnitude of these metabolic perturbations was closely correlated with patient cardiac dysfunction. This clinical/metabolic correlation was confirmed in a second blinded cohort of DCMA fibroblasts. Moreover, our metabolic flux diagnostic strategy correctly differentiated severe from mild DCMA cases with only one incorrect patient classification (positive predictive value 1.0 and negative predictive value 0.83). These findings suggest that glutamine catabolism is abnormal in DCMA and may serve as an early biomarker for predicting clinical progression.One Sentence SummaryAlterations in glutamine and lactate metabolism in patient-derived dermal fibroblasts are associated with the severity of cardiomyopathy in DCMA.

Published: October 2020

AbstractBackgroundSevere acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infection has disproportionately affected older individuals and those with underlying medical conditions. Research has focused on short-term outcomes in hospital, and single organ involvement. Consequently, impact of long COVID (persistent symptoms three months post-infection) across multiple organs in low-risk individuals is yet to be assessed.MethodsAn ongoing prospective, longitudinal, two-centre, observational study was performed in individuals symptomatic after recovery from acute SARS-CoV-2 infection. Symptoms and organ function (heart, lungs, kidneys, liver, pancreas, spleen) were assessed by standardised questionnaires (EQ-5D-5L, Dyspnoea-12), blood investigations and quantitative magnetic resonance imaging, defining single and multi-organ impairment by consensus definitions.FindingsBetween April and September 2020, 201 individuals (mean age 44 (SD 11.0) years, 70% female, 87% white, 31% healthcare workers) completed assessments following SARS-CoV-2 infection (median 140, IQR 105-160 days after initial symptoms). The prevalence of pre-existing conditions (obesity: 20%, hypertension: 6%; diabetes: 2%; heart disease: 4%) was low, and only 18% of individuals had been hospitalised with COVID-19. Fatigue (98%), muscle aches (88%), breathlessness (87%), and headaches (83%) were the most frequently reported symptoms. Ongoing cardiorespiratory (92%) and gastrointestinal (73%) symptoms were common, and 42% of individuals had ten or more symptoms.There was evidence of mild organ impairment in heart (32%), lungs (33%), kidneys (12%), liver (10%), pancreas (17%), and spleen (6%). Single (66%) and multi-organ (25%) impairment was observed, and was significantly associated with risk of prior COVID-19 hospitalisation (p<0.05).InterpretationIn a young, low-risk population with ongoing symptoms, almost 70% of individuals have impairment in one or more organs four months after initial symptoms of SARS-CoV-2 infection. There are implications not only for burden of long COVID but also public health approaches which have assumed low risk in young people with no comorbidities.FundingThis work was supported by the UK’s National Consortium of Intelligent Medical Imaging through the Industry Strategy Challenge Fund, Innovate UK Grant 104688, and also through the European Union’s Horizon 2020 research and innovation programme under grant agreement No 719445.
Quantum refinement with multiple conformations: application to the P-cluster in nitrogenase
Authors: Cao Lili , Ryde Ulf 
Published: October 2020

X-ray crystallography is the main source of atomistic information on the structure of proteins. Normal crystal structures are obtained as a compromise between the X-ray scattering data and a set of empirical restraints that ensure chemically reasonable bond lengths and angles. However, such restraints are not always available or accurate for nonstandard parts of the structure, for example substrates, inhibitors and metal sites. The method of quantum refinement, in which these empirical restraints are replaced by quantum-mechanical (QM) calculations, has previously been suggested for small but interesting parts of the protein. Here, this approach is extended to allow for multiple conformations in the QM region by performing separate QM calculations for each conformation. This approach is shown to work properly and leads to improved structures in terms of electron-density maps and real-space difference density Z-scores. It is also shown that the quality of the structures can be gauged using QM strain energies. The approach, called ComQumX-2QM, is applied to the P-cluster in two different crystal structures of the enzyme nitrogenase, i.e. an Fe8S7Cys6 cluster, used for electron transfer. One structure is at a very high resolution (1.0 Å) and shows a mixture of two different oxidation states, the fully reduced PN state (Fe8
2+, 20%) and the doubly oxidized P2+ state (80%). In the original crystal structure the coordinates differed for only two iron ions, but here it is shown that the two states also show differences in other atoms of up to 0.7 Å. The second structure is at a more modest resolution, 2.1 Å, and was originally suggested to show only the one-electron oxidized state, P1+. Here, it is shown that it is rather a 50/50% mixture of the P1+ and P2+ states and that many of the Fe—Fe and Fe—S distances in the original structure were quite inaccurate (by up to 0.8 Å). This shows that the new ComQumX-2QM approach can be used to sort out what is actually seen in crystal structures with dual conformations and to give locally improved coordinates.

Authors: Liu Lin , Lu Shuang , Wu Ya Qi , Xie Jin Yin , Xing Jinjuan 
Published: October 2020

Purpose
This paper aims to reduce environment pollution caused by benzotriazole. The authors chose one of the best inhibitors from 2-aminobenzimidazole, 2-methylbenzimidazol, 2-mercaptobenzimidazole and benzimidazole in combination with benzotriazole.

Design/methodology/approach
The electrochemical measurement indicated that 2-methylbenzimidazol had the best inhibition behavior. Then, it was mixed with benzotriazole. Techniques such as field emission scanning electron microscopy, atomic force microscopy, Raman spectroscopy and optical contact angle measurements were used.

Findings
The results showed that the inhibition efficiency was up to 99.98%, when the mixture concentration was 20 mmol/L and the molar ratio 1:1.

Originality/value
1-benzotriazole was mixed with 2-methylbenzimidazol for the first time. During the exist of methyl, 2-methylbenzimidazol has the better inhibition; this point was ignored by researchers.

Understanding the connection between SMEs’ competitiveness and cash flow generation: an empirical analysis from Hungary
Authors: Markus Gabor , Rideg Andras 
Published: October 2020

PurposeThe purpose of this paper is to interconnect the firm level competitive performance (competitiveness) to the financial performance of the firms. The goal is to give evidence on how successful small- and medium-sized enterprises (SMEs) use their financial performance to support their competitive performance.Design/methodology/approachCompetitiveness is interpreted and measured through the resource-based view theory on a wide range of competitiveness measurements with a sample size of 639 SMEs. Financial data originate from official, publicly accessible governmental archives. All data are from a mid-size Central European country (Hungary). To interconnect competitiveness and financial performance, this paper recognizes two types of cash flow, namely, cash flow to the “past” (dividend and debt service) and cash flow to the “future” (CAPEX and innovation). This paper used ordinary least squares regression and binomial logistic regression to analyze connections.FindingsCash flows to the “future” have much stronger effects on competitiveness than cash flows to the “past.” Debt services do not affect competitiveness, whereas dividends, CAPEX and innovation efforts have a significant positive connection to competitiveness, showing that higher cash flow indicates higher competitive performance. If this paper knows how much the firm spends on innovation and dividends, in about the four-fifths of the cases, this paper can predict the level of the competitiveness of the firm without any additional information. The level of these variables gives enough information, the variability of them is not relevant.Research limitations/implicationsThe explanatory power of future-oriented cash flow elements is much higher than that of the past-oriented ones, while innovation dominates all models. Firms with higher competitiveness build their returns in their cost structure, and only when the financial position of the firm is stable enough, withdraw the financial resource based on a long-term plan. The results are limited by the fact that using the current sample, detailed and representative (e.g. cross-industrial, spatial, etc.) decomposition is not possible.Originality/valueLiterature is focusing on how SMEs reach success, how SMEs “earn money.” There is no evidence on how SMEs “spend money,” earned during their success.
Time-cost-quality-environmental impact trade-off resource-constrained project scheduling problem with DEA approach
Authors: Banihashemi Sayyid Ali , Khalilzadeh Mohammad 
Published: October 2020

PurposeThe purpose of this paper is to evaluate project activities' efficiency in different execution modes for the optimization of time–cost-quality and environmental impacts trade-off problem.Design/methodology/approachThis paper presents a parallel Data Envelopment Analysis (DEA) method for evaluation of project activities with different execution modes to select the best execution mode and find a trade-off between objectives. Also, according to the nature of the project activities, outputs are categorized into desirable (quality) and undesirable (time, cost and environmental impacts) and analyzed based on the DEA model. In order to rank efficient execution modes, the ideal and anti-ideal virtual units method is used. The proposed model is implemented on a real case of a rural water supply construction project to demonstrate its validity.FindingsThe findings show that the use of the efficient execution mode in each activity leads to an optimal trade-off between the four project objectives (time, cost, quality and environmental impacts).Practical implicationsThis study help project managers and practitioners with choosing the most efficient execution modes of project activities taking time–cost-quality-environmental impacts into account.Originality/valueIn this paper, in addition to time and cost optimization of construction projects, quality factors and environmental impacts are considered. Further to the authors' knowledge, there is no method for evaluating project activities' efficiency. The efficiency of different activity modes is also evaluated for the first time to select the most efficient modes. This research can assist project managers with choosing the most appropriate execution modes for the activities to ultimately accomplish the project with the lowest time, cost and environmental impacts along with the highest quality.

Published: October 2020

PurposeAssessing the antecedents of innovation implementation holds importance for companies, as previous studies have shown that without proper implementation the innovation is doomed to fail. Over the past few years, research on innovation implementation is growing. However, the evidence on the antecedents of innovation implementation is inconsistent. The purpose of the study is to conduct a review of the literature using meta-analysis to summarize the divergent views present in the literature.Design/methodology/approachA meta-analysis technique is adopted for reviewing the literature. The literature search was conducted with selected keywords in different databases and top journals from the ABDC list (A* and A).FindingsThe results of the meta-analysis that summarize evidence from 42 papers, 100 effect sizes and 32,223 organizations show the significance and homogeneous/heterogeneous opinions of the past studies. Results reveal the homogeneity in antecedents such as transformational leadership, business collaboration, employee competency, leader competency, absorptive capacity and business size and heterogeneity in the antecedents such as communication, customer collaboration, internal entrainment, external entrainment, implementation climate and strategic resources.Research limitations/implicationsThe results imply that managers attempting to implement innovation in the organizations need to first focus on homogenous antecedents followed by heterogeneous antecedents for successful implementation.Originality/valueThis study advocates research on innovation implementation. It tests the significance, nature of the relationship and summarizes the divergent views on antecedents of innovation implementation in an organization. The results of this study can also be used in the theoretical advancement of management innovation literature.
Entrepreneurial ecosystem for tech start-ups in Bangalore: an exploration of structure and gap
Authors: Mungila Hillemane Bala Subrahmanya 
Published: October 2020

PurposeBangalore has gained international recognition as a technology start-up hub for its vibrant entrepreneurial ecosystem. Against this backdrop, this paper attempts to explore the structure and gap that exist with respect to the entrepreneurial ecosystem for tech start-ups in Bangalore.Design/methodology/approachA Delphi technique based four stage interaction with the experts/stakeholders belonging to different components of the entrepreneurial ecosystem (as identified from the literature) in the context of Bangalore is conducted, to gather primary data. This enabled us to define the structure of entrepreneurial ecosystem and analyse the gap that exists between an ideal ecosystem feasible in the Indian context and that one that prevailed in Bangalore.FindingsThe prevailing entrepreneurial ecosystem for tech start-ups in Bangalore is significantly different (lower) relative to an ideal ecosystem feasible in the Indian economic environment, as prescribed by the Delphi experts, both at the aggregate level and at an individual component level. The step-wise (backward) logistic regression analysis revealed that Bangalore ecosystem is primarily lacking in terms of one of the Triple Helices, namely, role of education and research institutions, and two of the five indispensable components, namely, market maturity and mentorship.Research limitations/implicationsIt is essential to strengthen and promote the Triple Helix base and the five indispensable components in an entrepreneurial ecosystem, to accelerate the emergence and growth of tech start-ups.Practical implicationsIt brings out the nature of entrepreneurial ecosystem structure and the gap between what can be considered an ideal ecosystem and what prevails in Bangalore currently.Originality/valueThis is a primary data based study, which has value for regional policy makers in strategizing to promote Bangalore ecosystem, and for researchers in undertaking “ecosystem gap analysis”.

Insights and future forward for fashion and textile value chain in Uzbekistan
Authors: Khurana Karan , Ataniyazova Zamira 
Published: October 2020

Purpose
Uzbekistan is one of the most prominent cotton producers since the soviet era, but it has struggled to establish a complete value chain. The country’s strategic location and industrial potential have not been harnessed accordingly. This paper aims to critically investigate the barriers in the value chain and propose solutions to the stakeholders in the sector.

Design/methodology/approach
The research involves both primary and secondary research methods. Value chain analysis method has been implemented to ground the theories and results. A systematic literature review was conducted to understand the current position in the world market. Official statistical data was collected from the government bodies to support the reflections of academic literature. Primary data was collected by conducting in-depth semi-structured interviews and questionnaires in 50 local textile companies. Finally, the authors have used their empirical evidences from emerging economies to provide solutions to the sector.

Findings
The value chain suffers a disconnect, as the emphasis has been on exporting cotton. Moreover, companies have a very limited technical know-how of supply chain management and hence no value addition to the raw material. The consumer relies on imports, as there is no significant participation from the Uzbek companies across the fashion segments. This is a major loss of earnings to the country.

Originality/value
Existing academic literature revolves around the cotton and silk industry, but, to the best of the authors’ knowledge, there is no study that unites the value chain and provides solutions to its stakeholders. This paper provides a socio-economic vision to the stakeholders, academia and industry so that the country can harness its potential and become one of the leading apparel producing nations in the future.
