scRNA-seq analysis of hemocytes of penaeid shrimp under virus infection
Authors: Koiwai Keiichiro , Kondo Hidehiro , Hirono Ikuo
Published: January 2023

The classification of cells in non-model organisms has lagged behind that of model organisms using established cluster of differentiation marker sets. To reduce fish diseases, research is needed to better understand immune-related cells, or hemocytes, in non-model organisms like shrimp and other marine invertebrates. In this study, we used Drop-seq to examine how virus infection affected the populations of hemocytes in kuruma shrimp,Penaeus japonicus, which had been artificially infected with a virus. The findings demonstrated that virus infection reduced particular cell populations in circulating hemolymph and inhibited the expression of antimicrobial peptides. We also identified the gene sets that are likely to be responsible for this reduction. Additionally, we identified functionally unknown genes as novel antimicrobial peptides, and we supported this assumption by the fact that these genes were expressed in the population of hemocytes that expressed other antimicrobial peptides. In addition, we aimed to improve the operability of the experiment by conducting Drop-seq with fixed cells as a template and discussed the impact of methanol fixation on Drop-seq data in comparison to previous results obtained without fixation. These results not only deepen our understanding of the immune system of crustaceans but also demonstrate that single-cell analysis can accelerate research on non-model organisms.

Appropriate risk evaluation is essential for survival in complex, uncertain environments. Confronted with choosing between certain (safe) and uncertain (risky) options, animals show strong preference for either option consistently across extended time periods. How such risk preference is encoded in the brain remains elusive. A candidate region is the lateral habenula (LHb), which is prominently involved in value-guided behavior. Here, using a balanced two-alternative choice task and longitudinal two-photon calcium imaging, we identify LHb neurons with risk-preference-selective activity reflecting individual risk preference prior to action selection. By employing whole-brain anatomical tracing, multi-fiber photometry, and projection- and cell-type-specific optogenetics, we find that glutamatergic LHb projections from the medial (MH) but not lateral (LH) hypothalamus provide behavior-relevant synaptic input before action selection. Optogenetic stimulation of MH→LHb axons evoked excitatory and inhibitory postsynaptic responses, whereas LH→LHb projections were excitatory. We thus reveal functionally distinct hypothalamus-habenula circuits for risk preference in habitual economic decision-making.
Personalized alpha-tACS targeting left posterior parietal cortex modulates visuo-spatial attention and posterior evoked EEG activity
Authors: Radecke Jan-Ole , Fiene Marina , Misselhorn Jonas , Herrmann Christoph S. , Engel Andreas K. , Wolters Carsten H. , Schneider Till R.
Published: January 2023

Background

Covert visuo-spatial attention is marked by the anticipatory lateralization of neuronal alpha activity in the posterior parietal cortex. Previous applications of transcranial alternating current stimulation (tACS) at the alpha frequency, however, were inconclusive regarding the causal contribution of oscillatory activity during visuo-spatial attention.

Objective

Attentional shifts of behavior and electroencephalography (EEG) after-effects were assessed in a cued visuo-spatial attention paradigm. We hypothesized that parietal alpha-tACS facilitates attention in the ipsilateral visual hemifield. Furthermore, we assumed that modulations of behavior and neurophysiology are related to individual electric field simulations.

Methods

We applied personalized tACS at alpha and gamma frequencies to elucidate the role of oscillatory neuronal activity for visuo-spatial attention. Personalized tACS montages were algorithmically optimized to target individual left and right parietal regions that were defined by an EEG localizer.

Results

Behavioral performance in the left hemifield was specifically increased by alpha-tACS compared to gamma-tACS targeting the left parietal cortex. This hemisphere-specific effect was observed despite the symmetry of simulated electric fields. In addition, visual event-related potential (ERP) amplitudes showed a reduced lateralization over posterior sites induced by left alpha-tACS. Neuronal sources of this effect were localized in the left premotor cortex. Interestingly, accuracy modulations induced by left parietal alpha-tACS were directly related to electric field magnitudes in the left premotor cortex.

Conclusion

Overall, results corroborate the notion that alpha lateralization plays a causal role in covert visuo-spatial attention and indicate an increased susceptibility of parietal and premotor brain regions of the left dorsal attention network to subtle tACS-neuromodulation.
Cell-type-specific propagation of visual flicker
Authors: Schneider Marius , Tzanou Athanasia , Uran Cem , Vinck Martin
Published: January 2023

Rhythmic flicker stimulation has gained interest as a treatment for neurodegenerative diseases and a method for frequency tagging neural activity in human EEG/MEG recordings. Yet, little is known about the way in which flicker-induced synchronization propagates across cortical levels and impacts different cell types. Here, we used Neuropixels to simultaneously record from LGN, V1, and CA1 while presenting visual flicker stimuli at different frequencies. LGN neurons showed strong phase locking up to 40Hz, whereas phase locking was substantially weaker in V1 units and absent in CA1 units. Laminar analyses revealed an attenuation of phase locking at 40Hz for each processing stage, with substantially weaker phase locking in the superficial layers of V1. Gamma-rhythmic flicker predominantly entrained fast-spiking interneurons. Optotagging experiments showed that these neurons correspond to either PV+ or narrow-waveform Sst+ neurons. A computational model could explain the observed differences in phase locking based on the neurons’ capacitative low-pass filtering properties. In summary, the propagation of synchronized activity and its effect on distinct cell types strongly depend on its frequency.
Understanding and evaluating ambiguity in single-cell and single-nucleus RNA-sequencing
Authors: He Dongze , Soneson Charlotte , Patro Rob
Published: January 2023

Recently, a new modification has been proposed by Hjörleifsson and Sullivanet al. to the model used to classify the splicing status of reads (as spliced (mature), unspliced (nascent), or ambiguous) in single-cell and single-nucleus RNA-seq data. Here, we evaluate both the theoretical basis and practical implementation of the proposed method. The proposed method is highly-conservative, and therefore, unlikely to mischaracterize reads as spliced (mature) or unspliced (nascent) when they are not. However, we find that it leaves a large fraction of reads classified as ambiguous, and, in practice, allocates these ambiguous reads in an all-or-nothing manner, and differently between single-cell and single-nucleus RNA-seq data. Further, as implemented in practice, the ambiguous classification is implicit and based on the index against which the reads are mapped, which leads to several drawbacks compared to methods that consider both spliced (mature) and unspliced (nascent) mapping targets simultaneously — for example, the ability to use confidently assigned reads to rescue ambiguous reads based on shared UMIs and gene targets. Nonetheless, we show that these conservative assignment rules can be obtained directly in existing approaches simply by altering the set of targets that are indexed. To this end, we introduce thespliceureference and show that its use withalevin-fryrecapitulates the more conservative proposed classification.

We also observe that, on experimental data, and under the proposed allocation rules for ambiguous UMIs, the difference between the proposed classification scheme and existing conventions appears much smaller than previously reported. We demonstrate the use of the newpiscemindex for mapping simultaneously against spliced (mature) and unspliced (nascent) targets, allowing classification against the full nascent and mature transcriptome in human or mouse in <3GB of memory. Finally, we discuss the potential of incorporating probabilistic evidence into the inference of splicing status, and suggest that it may provide benefits beyond what can be obtained from discrete classification of UMIs as splicing-ambiguous.

Published: January 2023

The investigated co-crystal of 3-chloro-N-methylpyridinium iodide with tetrabromoquinone (3-Cl-N-MePy·I·Br4Q) reveals a π-hole interaction between an iodide anion and a quinoid ring involving an n → π* charge transfer. The quinoid ring has a partial negative charge (estimated to be in the range 0.08–0.11e) and a partial radical character, which is related to the black colour of the crystals (crystals of neutral tetrabromoquinone are yellow). A detailed X-ray charge density study revealed two symmetry-independent bond critical points between the iodide anions and carbon atoms of the ring. Their maximum electron density of 0.065 e Å−3 was reproduced by quantum chemical modelling. The energy of the interaction is estimated to be −11.16 kcal mol−1, which is comparable to the strength of moderate hydrogen bonding (about −10 kcal mol−1); it is dominantly electrostatic in nature, with a considerable dispersion component.

Authors: Chen Jingjun , Tang Xiwen , Xia Yuan , Bao Shangfei , Shen Jianting
Published: January 2023

Purpose

This study aims to explore the influence of information presentation conditions on the flow experience of digital reading for high school students.

Design/methodology/approach

Firstly, a survey determines the preferred reading medium and the types of texts that high school students frequently read. Secondly, Experiment 1 focuses on the effects of the text type and reading medium on flow experience and reading comprehension. Finally, Experiment 2 addresses a narrative text presented on a smartphone, and discusses the influence of advance organizer, presentation format and page layout on flow experience and reading comprehension.

Findings

In digital reading, the narrative text has a stronger flow experience than explanatory text; the flow experience of reading narration on smartphones is more evident than on computers. The advance organizer and text combined with pictures are more conducive to a flow experience when a smartphone is used as a reading medium. From the perspective of reading comprehension, scrolling is more suitable for reading text combined with pictures and paging best suits pure text.

Originality/value

Through experimental methods, this study reveals the influence of information presentation conditions on the digital reading flow experience, which is a meaningful and innovative topic. The findings can provide more enlightenment and reference for the design and promotion of digital resources and digital reading by teenagers.

Published: January 2023

Purpose

Drawing on the person–supervisor fit theory, this study aims to adopts a dyadic and relational approach to investigate the congruence between the leader’s and the follower’s learning goal orientation (LGO) on their leader–member exchange (LMX) quality and the follower’s innovation.

Design/methodology/approach

The participants were 213 frontline employees and their 69 immediate supervisors from a large five-star hotel in China. The authors analyze the multiple-wave data using the cross-level polynomial regression approach.

Findings

The results show that when the levels of LGO between the leader and the follower are congruent, follower innovation and LMX are higher; when the levels of LGO between the leader and the follower are incongruent, it hinders LMX but benefits follower’s innovation.

Research limitations/implications

This study implies that personality congruence and incongruence can be equally important in creating positive work outcomes, enriching the theoretical understanding and practical implications for promoting LMX and follower innovation in hospitality industry.

Originality/value

Published: January 2023

Purpose

Based on text content analysis using big data, this study aims to explore differences in guest perceptions of peer-to-peer accommodations before and after COVID-19 to provide suggestions for the development of these properties in China postpandemic.

Design/methodology/approach

A guest perception dictionary was established by collecting Ctrip customer reviews of peer-to-peer accommodations. After data cleaning, thematic word analysis and semantic association network analysis were used to explore perceptions and thematic differences before and after COVID-19.

Findings

This research constructed a multidimensional framework of guest-perceived values for peer-to-peer accommodation in the context of COVID-19. The findings showed that the emphasis on functionality in peer-to-peer accommodation changed; perceived emotional values associated with peer-to-peer stays were more complex; perceived social values decreased, host–guest interactions were reduced and online communication became a stronger trend; tourist preferences for types of experiences changed, and people changed their destination selections; perceived conditional value was reflected in perceived risks, and the perceptions of environmental health, service and physical risks increased.

Research limitations/implications

This research has constructed a multidimensional framework of tourist perceived value on the basis of peer-to-peer accommodation context and epidemic background and has thus shown the changes in tourist perceived value of peer-to-peer accommodation before and after COVID-19.

Originality/value

To the best of authors’ knowledge, this research constitutes the first attempt to explore the perceptual differences for peer-to-peer accommodations before and after COVID-19 based on an extensive data set of online reviews from multiple provinces of China.
Determining the temperature ratings of infant bedding
Authors: Jiang Shu , Xu Xinyu , Wang Yunyi , Li Jun
Published: January 2023

Purpose

The purpose of this study is to determine the temperature ratings of infant bedding.

Design/methodology/approach

Mathematical models were developed for predicting temperature ratings of infant bedding for all age groups based on the thermal balance equation. These models were validated by the published physiological data and the baby manikin tests. The air temperature was compared with the predicted temperature rating, and the skin temperature of infant or baby manikin was used to explain the validation results.

Findings

The models had higher prediction accuracy, especially for the infant bedding with uniformly distributed thermal insulation. The results showed that an increase of 1 clo in thermal insulation caused a decrease of 4.2–6.0 °C in temperature rating. The slope of the model reduced with the increasing month-age, indicating that an older infant had a lower temperature rating than a younger infant.

Practical implications

Suggestions were given for caregivers that younger infants ought to be covered with more bedding than adults; however, older infants were expected to require less bedding.

Originality/value

The outcomes provided scientific guidelines on the selection of bedding for infants at a particular room temperature to ensure the health and safety of infants.
Maturity of information systems' security in Ethiopian banks: case of selected private banks
Authors: Shimels Tadele , Lessa Lemma
Published: January 2023

Purpose

Information systems' security is more critical than ever before since security threats are rapidly growing. Before putting in place information systems' security measures, organizations are required to determine the maturity level of their information security governance. Literature review reveals that there is no recent study on information systems' security maturity level of banks in Ethiopia. This study thus seeks to measure the existing maturity level and examine the security gaps in order to propose possible changes in Ethiopian private banking industry's information system security maturity indicators.

Design/methodology/approach

Four private banks are selected as a representative sample. The system security engineering capability maturity model (SSE-CMM) is used as the maturity measurement criteria, and the measurement was based on ISO/IEC 27001 information security control areas. The data for the study were gathered using a questionnaire.

Findings

A total of 93 valid questionnaires were gathered from 110 participants in the study. Based on the SSE-CMM maturity model assessment criteria the private banking industry's current maturity level is level 2 (repeatable but intuitive). Institutions have a pattern that is repeated when completing information security operations but its existence was not thoroughly proven and institutional inconsistency still exists.

Originality/value

This study seeks to measure the existing maturity level and examine the security gaps in order to propose possible changes in Ethiopian private banking industry's information system security maturity indicators. This topic has not been attempted previously in the context of Ethiopian financial sector.

Authors: Uyar Basar , Meydan Imren
Published: January 2023

Purpose

The aim of this paper is to study the effects of commercially available antioxidants on the oxidation stability of white mineral oils (paraffin oil).

Design/methodology/approach

Twelve commercially available antioxidants (Chimassorb 81, Tinuvin 326, Tinuvin 765, Tinuvin 571, Irganox L57, Irganox L109, Irganox L101, Irganox L115, Irganox L06, Irgafos 168, Naugard 445, BHT) were added to pharmaceutical and technical grade white mineral oils at 0.1%, 0.2%, 0.3%, 0.6% and 0.8% (w/w) concentrations. Light, heat and oxygen were applied to induce and accelerate oxidation. Total acid number, viscosity and 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity of the oils were measured to evaluate the performance of the antioxidant additives.

Findings

Results showed that combined heat and oxygen treatment was the most effective of the three conditions tested to cause oxidation. Based on the data, the best antioxidant additives to be used in white oils are decided to be Irganox L06 and Irganox L101. It was also found that the grade of oils (technical or pharma) did not create a significant difference in the results obtained.

Originality/value

To the best of the authors’ knowledge, this is the first study that reports effects of antioxidant addition on the oxidative properties of white mineral oils. This study advances knowledge of the behavior of white mineral oils under real atmosphere and provides comprehensive data on how the antioxidants affect the light, thermal, oxidative degradation of white mineral oils. The data presented also provide an insight to extend life expectancy of white mineral oils.

Authors: Zainurin Muhammad Zekree Leong , Haji Masri Masairol , Besar Mohd Hairul Azrin , Anshari Muhammad
Published: January 2023

Purpose

This study aims to synthesize the current literature and present a definition of future smart banking services known as “metaverse banking” as well as to discuss its future potential.

Design/methodology/approach

This paper proposes a suitable definition for metaverse banking that includes the important elements of metaverse banking and sheds light on its impending potential from distinct aspects.

Findings

Metaverse banking is a banking channel actualized through the integration of metaverse and online banking services, enabled by a mix of numerous advanced technologies, that provides customers with synchronous banking services accompanied with 3D experiences in a virtual world. There is a high likelihood in the future that metaverse banking is able to be marketed intensively yet effectively, and incur progressive demands, as well as progress significantly in terms of development.

Practical implications

This study assists bank managers in understanding metaverse banking better and simultaneously makes them realize the metaverse banking’ growth opportunity which can be pursued.

Originality/value

To the best of the authors’ knowledge, this is the first paper to establish a definition for metaverse banking and expound on the upcoming potential of metaverse banking. There is a lack of related literature because this concept is relatively new. This study assists in enriching the concept and providing future research directions.
Interprofessional learning through discussions of troubled sex/gender in mental health care: a case study
Authors: Viking Tuija , Skyvell Nilsson Maria , Wernersson Inga
Published: January 2023

Purpose

This study aims to investigate how aspects of the sex/gender were scrutinized in a team’s production of clinical guidelines for psychiatric compulsory care and what the implications were for the final guidelines and for interprofessional learning.

Design/methodology/approach

The study is a case study, where interviews were conducted and a narrative analysis was used.

Findings

The results reflected how sex/gender arose in a discussion about gender differences when using restraining belts. Furthermore, discussions are presented where profession-specific experiences and knowledge about sex/gender appeared to stimulate interprofessional learning. However, the team’s learning about the complexity of sex/gender resulted in guidelines that emphasized aspects of power and focused on the individual patient. Thus, discussions leading to analysis and learning related to gender paradoxically produced guidelines that were gender-neutral.

Originality/value

The study highlights the potential interprofessional learning in discussions of sex/gender and its complex relation in medicine.
Public information needs during the COVID-19 outbreak: a qualitative study in mainland China
Authors: Yi Yuan , Chiu Dickson K.W.
Published: January 2023

Purpose

The impact of COVID-19 has led to a surge in the public’s reliance on the Internet for pandemic information, and the policy of home isolation has exacerbated this. This study aimed to investigate public information needs and ways of accessing and disseminating information during COVID-19 in mainland China.

Design/methodology/approach

This study used a qualitative research approach to conduct semi-structured interviews with 15 participants from 9 cities in mainland China about information needs and access behaviors during the COVID-19 outbreak. All interview recordings were converted into text and proofread, then coded and summarised in correspondence with the research questions using the grounded theory.

Findings

This study summarized the dynamics of public information needs during the 2.5-year pandemic and identified the difficulties in accessing certain information.

Originality/value

Although information needs of public health emergencies have been a hot topic during COVID-19, scant studies focus on information needs in specific countries in Asia, especially in mainland China, the first country with a major outbreak and stringent lockdown mandates. Therefore, the current study is well enriched by focusing on information demand behavior in the context of COVID-19. Possible measures for improvement were also given to existing and potential problems, taking into account the participants’ views.

Authors: Mohamed Mohamed Hamdy , Mohamed Wael Sabry
Published: January 2023

Purpose

This study aims to offer an effective nanocomposite for potential use to consolidate and protect deteriorated archaeological pottery.

Design/methodology/approach

Three nanocomposites were used in the experimental study. This study used nano Primal AC33, silicon dioxide (SiO2) and montmorillonite (MMT) nanoparticles to protect and consolidate pottery specimens. Pottery specimens were made at 800°C for this investigation. Consolidation materials were applied with a brush. The properties of the treated pottery specimens were assessed using several methods such as digital and scanning electron microscopes, static water contact angle, color alteration, physical properties and compressive strength.

Findings

Microscopic examination indicated the ability of the nano Primal AC33/MMT nanocomposites to cover the outer surface well and bind the inner granules. Concerning specimens with code F treated with nano Primal AC33 5%/MMT 3% nanocomposites, it achieved an increase in contact angle (120°), density (1.23 g/cm3) and compressive strength (561 kg/cm2), as well as a decrease in color change (ΔE = 2.62), water absorption (4.45%) and porosity (5.46%). The novelty of the results is due to the characteristics of nano Primal AC33 5%/MMT 3% nanocomposites used in the current study.

Originality/value

This study describes the significant results of the analytical methods used for evaluating consolidation materials used in this study. The findings offer useful information for the protection of archaeological pottery. The investigation indicated that nano Primal AC33 5%/MMT 3% nanocomposites gave the best results. Therefore, it is recommended to use this nanocomposite to consolidate archaeological pottery. As a result, the current work provides a promising first step in conserving archaeological pottery for future studies.
Factors influencing Brazilian sugar and ethanol refineries’ failure
Authors: Higashi Susan Yuko , Caleman Silvia Morales de Queiroz , Manning Louise , De Aguiar Luis Kluwe , Monteiro Guilherme Fowler A.
Published: January 2023

Purpose

This study aims to examine the dimensions of organisational failure in the Brazilian sugarcane and ethanol refineries, as reported in judicial recovery plans.

Design/methodology/approach

This paper follows a qualitative, inductive approach that uses content analysis to examine the details of recovery plans. Besides, a cause-and-effect relationship diagram is proposed, making it possible to identify the interconnections between the identified variables.

Findings

There is evidence that organisational failures are not a linear outcome. Organisational failures are complex and occur because of several factors, often interdependent and operating at different levels.

Research limitations/implications

Organisational failures basically have three interrelated levels: the macro-level (external environment), the meso-level (organisational environment) and the micro-level (associated with the decision-maker). The relationship between these levels is not trivial and involves coordinated research efforts.

Practical implications

Organisations must consider all types of failure levels when developing business reorganisation plans. Reorganisation plans are more than a formal document to achieve judicial recovery, as they should incorporate strategic factors.

Social implications

Organisational failures are regularity in organisations’ day-to-day. Understanding failure’s sources is vital to design firms’ strategies and public policies.

Originality/value

The study of organisational failure involves the analysis of complex and multidimensional phenomena. Judicial recovery plans are the means for companies to get a second chance. To that end, this paper addresses the sources of organisational failures through the lens of judicial plans.
The linkage between corporate social responsibility and the main benefits obtained from the integration of multiple management systems in Bangladesh
Authors: Talapatra Subrata , Uddin Kutub , Doiro Manuel , Santos Gilberto
Published: January 2023

Purpose

The aim of this study is to investigate the perceived benefits offered by integrated management system (IMS) in the readymade garments (RMG) sector in Bangladesh and the respective linkage with corporate social responsibility (CSR) to promote sustainable development. This study presents a list of IMS benefits composed of different international management standards according to ISO 9001:2015, ISO 14001:2015, OSHAS 18001: 2007 and SA 8000:2014.

Design/methodology/approach

To identify the possible benefits of IMS, a systematic literature review was conducted from 2009 to 2019, namely, in the database of Elsevier, Emerald and John Wiley. A questionnaire survey was developed with the purpose of examining the perceived main benefits of IMS. The questionnaire was e-mailed to 355 representatives of 15 RMG sectors in Bangladesh. A total of 256 complete and useable responses were received, constituting the base of this work. Subsequently, statistical analysis was conducted using SPSS 20 software.

Findings

The main findings of the present study show that the most important five benefits of IMS in RMG sector in Bangladesh are better capacity to achieve organization’s objectives, optimum use of various resources, business sustainability, synergies of different management policies and reduction of duplication efforts.

Practical implications

Two major limitations of the study are as follows: first, it is not a longitudinal study; second, IMS benefits were examined in the national sector context. The present study has both theoretical and practical implications. The study presents a comprehensive list of IMS benefits that contribute to the existing literature from a theoretical point of view. On the other hand and from a practical point of view, this study encourages managers to implement IMS in their organizations.

Originality/value

This study helps in understanding the contribution of IMS benefits to cleaner production and CSR in Bangladesh. The focus on the benefits of IMS in the RMG sector in Bangladesh is another significant aspect of this study because it promotes the development of environmental policies linked to CSR with stakeholder engagement, as a driver to sustainable development.
To colour a bird: The evolution of carotenoid‐based colouration in passerines is shaped by sexual selection, ecology and life history
Authors: Willink Beatriz , Wu Meng Y.
Published: January 2023

Research Highlight: Delhey, K., Valcu, M., Dale, J., & Kempenaers, B. (2022). The evolution of carotenoid‐based plumage colours in passerine birds. Journal of Animal Ecology, https://doi.org/10.1111/1365‐2656.13791. Carotenoids, a class of colour pigments, are responsible for red, yellow and orange hues in nature. They play an important role in visual animals, and specially birds, where dietary carotenoids can act as honest sexual signals. Long‐standing interest in the function of carotenoid‐based colours has led to different hypotheses for their evolutionary drivers. Yet, comparative studies testing the generality of these hypotheses have been previously limited in phylogenetic scope or resolution. In a recent study, Delhey et al. (2022) combined sexual dichromatism, life history and environmental data to investigate the evolution of carotenoid‐based colouration in the largest avian radiation, the passerines (Order: Passeriformes). The authors show that the expression of carotenoid‐based colours depends on environmental availability, dietary content and body size. They also show that red carotenoids are more often evolutionarily and metabolically derived, and suggest different colours are favoured by natural and sexual selection. These findings shine new light on commonly held hypotheses of carotenoid‐colour evolution and contribute to our understanding of how phenotypic diversity evolves.
The effect of methane and methanol on the terrestrial ammonia‐oxidizing archaeon ‘Candidatus Nitrosocosmicus franklandus C13’
Authors: Oudova‐Rivera Barbora , Wright Chloe L. , Crombie Andrew T. , Murrell J. Colin , Lehtovirta‐Morley Laura E.
Published: January 2023

The ammonia monooxygenase (AMO) is a key enzyme in ammonia‐oxidizing archaea, which are abundant and ubiquitous in soil environments. The AMO belongs to the copper‐containing membrane monooxygenase (CuMMO) enzyme superfamily, which also contains particulate methane monooxygenase (pMMO). Enzymes in the CuMMO superfamily are promiscuous, which results in co‐oxidation of alternative substrates. The phylogenetic and structural similarity between the pMMO and the archaeal AMO is well‐established, but there is surprisingly little information on the influence of methane and methanol on the archaeal AMO and terrestrial nitrification. The aim of this study was to examine the effects of methane and methanol on the soil ammonia‐oxidizing archaeon ‘Candidatus Nitrosocosmicus franklandus C13’. We demonstrate that both methane and methanol are competitive inhibitors of the archaeal AMO. The inhibition constants (Ki) for methane and methanol were 2.2 and 20 μM, respectively, concentrations which are environmentally relevant and orders of magnitude lower than those previously reported for ammonia‐oxidizing bacteria. Furthermore, we demonstrate that a specific suite of proteins is upregulated and downregulated in ‘Ca. Nitrosocosmicus franklandus C13’ in the presence of methane or methanol, which provides a foundation for future studies into metabolism of one‐carbon (C1) compounds in ammonia‐oxidizing archaea.

Aphelenchoides besseyi is a plant‐parasitic nematode (PPN) in the family Aphelenchoididae capable of infecting more than 200 plant species. A. besseyi is also a species complex with strains exhibiting varying pathogenicity to plants. We present the genome and annotations of six Aphelenchoides species, four of which belonged to the A. besseyi species complex. Most Aphelenchoides genomes have a size of 44.7–47.4 Mb and are among the smallest in clade IV, with the exception of A. fujianensis, which has a size of 143.8 Mb and is one of the largest. Phylogenomic analysis successfully delimited the species complex into A. oryzae and A. pseudobesseyi and revealed a reduction of transposon elements in the last common ancestor of Aphelenchoides. Synteny analyses between reference genomes indicated that three chromosomes in A. besseyi were derived from fission and fusion events. A systematic identification of horizontal gene transfer (HGT) genes across 27 representative nematodes allowed us to identify two major episodes of acquisition corresponding to the last common ancestor of clade IV or major PPNs, respectively. These genes were mostly lost and differentially retained between clades or strains. Most HGT events were acquired from bacteria, followed by fungi, and also from plants; plant HGT was especially prevalent in Bursaphelenchus mucronatus. Our results comprehensively improve the understanding of HGT in nematodes.

The variations in source rocks and melting conditions of granites can provide essential clues for the crustal magmatic response in orogenic process. Based on geochronology, whole‐rock and mineral chemistry, this paper reveals two different granites in the Northern Qinling migmatite complex, which reveal obvious differences in source region and melting condition. The older granodiorite (402 ± 0.8 Ma) displays typical Na‐rich adakite affinity, i.e., high Na2O/K2O (2.04 to 2.64) and Sr/Y (96 to 117) ratios, they have relative evolved isotopic compositions (εNd(t) = –0.52 to –0.04; zircon εHf(t) = –0.06 to +7.78). The younger leucogranite (371 ± 2 Ma) displays higher SiO2 (72.32 to 73.45 wt%), lower (TFeO + MgO + CaO + TiO2) contents (<2 wt%) and depleted Sr‐Nd‐Hf isotopic compositions (i.e., εNd(t) = +2.6 to +3.0; zircon εHf(t) = +5.94 to +14.12), as well as high 10000 × Ga/Al and TFeO/MgO ratios, indicating that they represent highly fractionated I‐type granites that derived from melting of juvenile crust. The variations in source rocks and melting condition of the two granites indicating a tectonic switch from compression to extension in 400 to 370 Ma, this switch is later than that in the eastern section of the North Qinling, indicating a scissor collision process between the South Qinling and North China Craton (NCC) in Devonian era.

The bedrock weathered crust in front of the Altun Mountains in the Qaidam Basin, western China, is different from others because this is a salt‐lake basin, where saline water fluid infiltrates and is deposited in the overlying strata. A large amount of gypsum infills the bedrock weathered crust, and this has changed the pore structure. Using core observation, polarized light microscopy, electron probe, physical property analysis and field emission scanning electron microscopy experiments, the characteristics of the weathered bedrock have been studied. There are cracks and a small number of dissolved pores in the interior of the weathered crust. Matrix micropores are widely developed, especially the various matrix cracks formed by tectonics and weathering, as well as the stress characteristics of small dissolved pores, and physical properties such as porosity and permeability. This ‘dual structure’ developed in the bedrock is important for guiding the exploration of the lake basin bedrock for natural gas.

China has a long history of pig breeding and a number of local breeds. The Songliao Black pig, bred in China in 2009, shows high variation in backfat thickness and therefore is well‐suited to fat deposition research. Fat deposition is a complex trait, and the underlying regulatory factors are not fully characterized. In this study, the molecular basis of fat deposition traits was evaluated by comparisons between three individuals with extremely high‐backfat thickness and three with extremely low‐backfat thickness selected from 53 gilts. Subcutaneous adipose tissues of the back were collected for strand‐specific library RNA sequencing (RNA‐seq) and small RNA‐seq. We identified 13 184 mRNAs, 2046 long non‐coding (lnc)RNAs, and 494 micro (mi)RNAs by high‐throughput sequencing. Furthermore, we detected 150 differentially expressed mRNAs, 66 differentially expressed lncRNAs, and eight differentially expressed miRNAs. A functional enrichment analysis indicated that these genes are involved in multiple fat metabolism‐related pathways, including positive regulation of fat cell differentiation, and fat digestion and absorption. We used various algorithms (miRanda, TargetScan, and RNAhybrid) to predict targeting relationships and constructed a competing endogenous RNA network containing seven lncRNAs, three miRNAs, and six mRNAs. All these genes were differentially expressed between the extremely high and low backfat thickness groups or enriched in pathways related to fat metabolism. Our results provide insight into the regulatory mechanisms by which non‐coding RNAs and their target genes influence backfat deposition in pigs. Furthermore, our newly constructed competing endogenous RNA (lncRNA‐miRNA‐mRNA) network provides a basis for further exploration of fat deposition traits and non‐coding RNA functions.
Does Information Disclosed in “Use of Proceeds” from Prospectuses Affect IPO Initial Underpricing?
Authors: Tang Wenxiu , Zhou Zhong‐Guo
Published: January 2023

We study the impact of intended use of proceeds disclosed in the section of “Use of Proceeds” in prospectuses on ChiNext IPOs' initial underpricing. After splitting the entire period into two non‐overlapping sub‐periods to control for regulatory changes and after controlling for the firm‐level characteristics and market conditions, we find that the overall information disclosed from “Use of Proceeds” affects IPO initial underpricing significantly over the two sub‐periods. Moreover, the intended use of IPO proceeds in several specific categories affects underpricing too. The proceeds raised for IPO firms' information platform and research and development over the second sub‐period while the proceeds to promote marketing and sales and to expand existing products over the first sub‐period are significantly and positively related to initial underpricing. The significance changes for the IPOs with the opportunity to change their use of proceeds after IPOs. We explore the causes and effects to explain our findings.
