Published: December 2022

AbstractSlow conformational changes are often directly linked to protein function. It is however less clear how such processes may perturb the overall folding stability of a protein. We previously found that the stabilizing double mutant L49I/I57V in the small protein chymotrypsin inhibitor 2 from barley led to distributed increased nano second and faster dynamics. Here we asked what effect this mutant and the two individual mutants L49I and I57V have on the slow conformational dynamics of CI2. We used15N CPMG spin relaxation dispersion experiments to measure the kinetics, thermodynamics and structural changes associated with slow conformational change in CI2. These changes result in an excited state that is populated to 4.3% at 1 °C. As the temperature is increased the population of the excited state decreases. Structural changes in the transition to the excited state are associated with residues that interact with water molecules that have well defined positions and are found at these positions in all crystal structures of CI2. The mutations in CI2 have only little effect on the structure of the excited state whereas the stability of the excited state to some extent follows the stability of the main state. The minor state is thus most populated for the most stable CI2 variant and least populated for the least stable variant. We hypothesize that the interactions between the mutated residues and the well-ordered water molecules links subtle structural changes around the mutated residues to the region in the protein that experience slow conformational changes.

AbstractSocial anxiety disorder (SAD) is a psychiatric disorder characterized by severe fear in social situations and avoidance of these. Multiple genetic as well as environmental factors contribute to the etiopathology of SAD. One of the main risk factors for SAD is stress, especially during early periods of life (early life adversity; ELA). ELA leads to structural and regulatory alterations contributing to disease vulnerability. This includes the dysregulation of the immune response. However, the molecular link between ELA and the risk for SAD in adulthood remain largely unclear. Evidence is emerging that long-lasting changes of gene expression patterns play an important role in the biological mechanisms linking ELA and SAD.Therefore, we performed a transcriptome study of SAD and ELA using RNA sequencing. Analyzing differential gene expression, 13 significantly differentially expressed genes (DEGs) were identified with respect to SAD whilst no significant differences in expression were identified with respect to ELA. The most significantly expressed gene wasMAPK3being upregulated in the SAD group compared to control individuals. In contrary, weighted gene co-expression network analyses (WGCNA) identified only modules significantly associated with ELA, not with SAD. Furthermore, analyzing interaction networks of the genes from the ELA-associated modules and the SAD-related MAPK3) revealed complex interactions of those genes. Gene functional enrichment analyses indicate a role of signal transduction pathways as well as inflammatory responses supporting an involvement of the immune system in the association of ELA and SAD.In conclusion, we did not identify a direct molecular link between ELA and adult SAD by transcriptional changes. However, our data indicate an indirect association of ELA and SAD mediated by the interaction of genes involved in immune-related signal transduction.

AbstractAneuploidy is generally considered harmful, but in some microorganisms, it can act as an adaptive mechanism against environmental stresses. Here, we usedLeishmania– a protozoan parasite with a remarkable genome plasticity – to study the early evolution of aneuploidy under high drug pressure (antimony or miltefosine) as stressor model. By combining single-cell genomics, lineage tracing with cellular barcodes and longitudinal genome characterization, we revealed that antimony-induced aneuploidy changes result from the polyclonal selection of pre-existing karyotypes, complemented by further and rapid de novo alterations in chromosome copy number along evolution. In the case of miltefosine, early parasite adaptation was associated with independent pre-existing point mutations in a miltefosine transporter gene and aneuploidy changes only emerged later, upon exposure to increased concentration of the drug. Thus, polyclonality and genome plasticity are hallmarks of parasite adaptation, but the scenario of aneuploidy dynamics is dependent on the nature and strength of the environmental stress as well as on the existence of other pre-adaptive mechanisms.

Published: December 2022

AbstractProtein assembly defects due to enrichment of aberrant conformational variants of proteins are emerging as a new frontier in therapeutics design. Understanding, atomistically, structural elements that remodel the energy landscape of proteins, with the consequence of rewiring the conformational dynamics of proteins and pathologically perturbing functionally-oriented ensembles, is key for development of inhibitors. This is particularly relevant for molecular chaperones, hub proteins for the assembly of large multiprotein complexes, where enrichment of aberrant conformers can have a large impact on the cellular proteome, and in turn, on phenotypes. Here, we integrate computational and experimental tools to unveil howN-glycosylation of specific residues in glucose-regulated protein 94 (GRP94) modulates internal dynamics and alters the conformational fitness of regions fundamental for interaction with the nucleotide and synthetic ligands, and impacts substructures dedicated to recognition of interacting proteins. We show howN-glycosylation plays an active role in modulating the energy landscape of the protein, with specific glycosylation patterns determining specific functionally-oriented dynamic signatures. Our results provide support for leveraging the structural-dynamics knowledge on distinct glycosylation variants to design molecules targeting GRP94 disease-associated conformational states and assemblies. Since glycosylation is the most abundant form of post-translational modification, our results and mechanistic models can readily be transferred to other targets and contexts for cancers and other diseases.

Published: December 2022

AbstractComputational deconvolution with single-cell RNA sequencing data as reference is pivotal to interpreting spatial transcriptomics data, but the current methods are limited to cell type resolution. Here we present Redeconve, an algorithm to deconvolute spatial transcriptomics data at single-cell resolution, enabling interpretation of spatial transcriptomics data with thousands of nuanced cell states. We benchmarked Redeconve with the state-of-the-art algorithms on diverse spatial transcriptomics datasets and platforms and demonstrated the superiority of Redeconve in terms of accuracy, resolution, robustness, and speed. Applications to a human pancreatic cancer dataset revealed cancer clone-specific T cell infiltration, and application to lymph node samples identified subtle cellular surroundings between IgA+ and IgG+ spots, providing novel insights into tumor immunology and the regulatory mechanisms underlying antibody class switch.
State-of-the-art image and video quality assessment with a metric based on an intrinsically nonlinear neural summation model
Authors: Luna Raúl , Zabaleta Itziar , Bertalmío Marcelo 
Published: December 2022

AbstractThe development of automatic methods for image and video quality assessment that correlate well with the perception of human observers is a very challenging open problem in vision science, with numerous practical applications in disciplines such as image processing and computer vision, as well as in the media industry. In the past two decades, the goal of image quality research has been to improve upon classical metrics by developing models that emulate some aspects of the visual system, and while the progress has been considerable, state-of-the-art quality assessment methods still share a number of shortcomings, like their performance dropping considerably when they are tested on a database that is quite different from the one used to train them, or their significant limitations in predicting observer scores for high framerate videos. In this work we propose a novel objective method for image and video quality assessment that is based on the recently introduced Intrinsically Non-linear Receptive Field (INRF) formulation, a neural summation model that has been shown to be better at predicting neural activity and visual perception phenomena than the classical linear receptive field. Here we start by optimizing, on a classic image quality database, the four parameters of a very simple INRF-based metric, and proceed to test this metric on three other databases, showing that its performance equals or surpasses that of the state-of-the-art methods, some of them having millions of parameters. Next, we extend to the temporal domain this INRF image quality metric, and test it on several popular video quality datasets; again, the results of our proposed INRF-based video quality metric are shown to be very competitive.

Published: December 2022

PurposeThis paper constructs the uncertainty analysis model of prefabricated building supply chain risk. The model is designed to study the formation path of prefabricated building supply chain risk and is expected to be used by industry stakeholders for supply chain risk management.Design/methodology/approachBased on the uncertainty circle model, construct a configuration analysis framework for supply chain risks in prefabricated buildings. The fuzzy set qualitative comparative analysis (fsQCA) is used to study the configuration influence of five uncertain factors, including environment, plan-control, demand-supply, manufacturing and assembly-transportation, on the risk of the prefabricated building supply chain.FindingsThere are three paths to promote the high-risk generation of the prefabricated building supply chain: assembly-transportation-oriented, plan-control-oriented and manufacturing-oriented. There is a specific equivalent substitution relationship among the five causal conditions. Under specific conditions, different combinations of conditions have the same effect on promoting supply chain high-risk generation through equivalent substitution.Originality/valueThe multiple concurrent causal relationships of risk conditions in the assembly construction supply chain are studied under the grouping perspective, which helps to expand the research perspective of assembly construction supply chain risk and provides theoretical guidance for supply chain risk management of construction enterprises.
Leading change and innovation in Ghana’s banking sector: the mediating role of work autonomy
Authors: Kpinpuo Stephen Debar , Akolgo Isaac Gumah , Naimi Linda 
Published: December 2022

Purpose
In recent times, employers are routinely advertising for position candidates with the capability to work with little or no supervision at all. This is probably because, as businesses strive to globalize operations, supervision has become both complex and expensive. While the general interest in employees with considerable levels of work autonomy may be a strategic one, particularly for banks, it is important to determine the impact of work autonomy on other critical success factors such as employee commitment to change management, innovativeness and quality supervisor-subordinate relationship. This study aims to examine the relationship between these variables by exploring the mediation effect of work autonomy on the relationship between employee innovativeness, quality of supervisor-subordination collaboration and employee commitment to change management in the banking sector of Ghana.

Design/methodology/approach
The study used quantitative empirical strategies involving the distribution of questionnaires to a randomly selected sample of 400 employees of selected banks in Ghana. Data, so collected, were analysed using the PLS-SEM Software.

Findings
Results of the study revealed significant relationships between the quality of supervisor-subordinate collaboration, innovativeness and commitment to change. The findings further established work autonomy as an explanatory variable between the three employee behaviours – innovativeness, quality of supervisor-subordinate connection and commitment to change.

Originality/value
The novelty of this study lies in the interplay of quality employee relations, innovative employee behaviour and commitment to change processes as refereed by work autonomy to promote effective change management activities in Ghanaian banks. The outcome of the study led to the development of a theoretical model for organizational change management.

Working with patients with disruptions in symbolic capacity1
Authors: Winborn Mark 
Published: December 2022

AbstractThis article focuses on understanding and working with patients who have poorly developed symbolic capacity, or for whom symbolic capacity has been disrupted due to trauma, particularly as it pertains to the use of reverie and interpretation in the analytic process. Many patients who present for Jungian analysis will initially present with deficits in symbolic functioning. This situation results in necessary limitations or modifications in utilizing traditional Jungian techniques such as dream analysis, active imagination, sand tray and other expressive art techniques. The initial phase of analytic work with these patients requires a focus on developing their symbolic capacity before traditional Jungian techniques can be utilized effectively. During the paper Jung's concept of ‘the symbolic attitude’ will be examined as well as the conceptual models of Wilfred Bion and other post‐Bionians who outline theories and method for cultivating symbolic capacity and reflective functioning in patients for whom these capacities are impaired or poorly developed.

AbstractThe impact of factors such as density dependence, food availability and weather are known to be important for predicting population change in a wide range of species. However, a challenge in ecology is understanding the contributory and interactive role of these drivers on populations. This is necessary to design effective conservation and management strategies. Using data from long‐term studies of five hazel dormouse Muscardinus avellanarius populations in Europe, we tested the relationship between population density and weather and their impact on demographic rates. We used an integrated population modelling approach, estimating age‐specific overwinter survival, annual population growth and fecundity rates. We found strong negative effects of population density, precipitation and winter temperature on population growth rates. This suggests that warmer and wetter weather negatively affects dormouse survival for both adults and juveniles, but we found subtle differences in these effects between age classes. We also identified an interaction between weather measures and population density on age‐specific survival, possibly as a result of weather impacts during hibernation. Although we found low winter temperature was positively associated with population growth, we found evidence consistent with density dependence. We discuss our results in the context of woodland habitat conservation management.

AbstractIntroductionLong‐term kidney transplantation (KT) results in patients with familial Mediterranean fever (FMF)‐related amyloidosis are not well studied. This study reviewed the long‐term survival outcomes of FMF patients who underwent KT.MethodsWe compared the outcomes of 31 patients who underwent (KT) for biopsy‐proven amyloidosis secondary to FMF with 31 control patients (five with diabetes mellitus and 26 with nondiabetic kidney disease) undergoing KT between 1994 and 2021 at Başkent University Hospital. All data were recorded retrospectively from patients’ files.Results: The median age (quartile deviationQD) at the time of KT in the FMF and control group were 31 (6.7) and 33 (11), respectively. The median follow‐up period (QD) after KT was 108 (57) months in the FMF and 132 (72) months in the control group. In the FMF group, graft and patient survivals were 71% and 84% at 5 years and 45% and 48% at 10 years, respectively. In the control group, graft and patient survivals were 79% and 100% at 5 years and 63% and 71% at 10 years, respectively. Patient survival in the FMF group at 5 years was significantly lower than in the control group (p = .045). There was no statistically significant difference between the FMF and control groups in terms of graft and patient survival, and serum creatinine levels at 10 years. All patients were given triple immunosuppressive treatment with cyclosporine, mycophenolate mofetil, and prednisolone. Three patients received anakinra and one received canakinumab in addition to colchicine treatment. One FMF patient also underwent heart transplantation due to AA amyloidosis. Of the FMF patients, 11 died during follow‐up.ConclusionWe have found that the long‐term outcome of KT in patients with FMF amyloidosis is numerically worse but not statistically different from the control group. However, short‐ and long‐term complications still need to be resolved.
