Published: February 2024

AbstractThe increased importance of nanostructured lignin exhibits a plethora of multifunctional groups, making it a highly adaptable material basis with significant potential for use in the rapidly expanding composite sector. Initially, lignin nanoparticles (NPs) were incorporated into epoxy networks via an in situ polymerization process where isophorone diamine functioned as a hardener to produce lignin/epoxy resin nanocomposites (lignin@TN). These lignin@TN exhibit promising characteristics, enhancing UV‐blocking efficiency (35.69% at 404 nm with 3.72 wt% lignin) in transparent nanocomposite films while simultaneously improving mechanical properties compared with neat epoxy resin. Adding lignin nanoparticles to epoxy nanocomposites boost up tensile strength by an impressive 24% compared with the pristine epoxy but it affected the glass transition temperature (Tg). After all, this study has opened new possibilities for utilizing renewable, sustainable, and economic lignin feedstocks as a potential ingredient for reinforcing with thermoset polymers like epoxy.

Published: February 2024

AbstractPlant protein‐based adhesives, particularly those derived from soybean meal (SM), have been available for various product applications. However, the high cost of SM has limited large‐scale manufacturing, despite sufficient production capacity. Peony seed meal (PSM) is abundant in proteins, polysaccharides, and polyphenols, the protein in PSM contains highly hydrophobic amino acids, resulting in low water solubility and water holding capacity. It is worth investigating whether the unique composition of hydrophobic amino acids in PSM protein can enhance the water resistance of PSM‐based adhesives. Additionally, the lower price of PSM, which is approximately two‐thirds of the cost of SM, makes it a more valuable raw material for adhesives. Herein, we report a simple and practical approach for preparing PSM‐based wood adhesives by utilizing the highly active cross‐linking agent of polyamidoamine‐epichlorohydrin (PAE). The results showed PSM‐based adhesives possessed excellent adhesion, especially the adhesive of “PSM‐36%”, with the wet bond strength and the aged bond strength reaching 1.60 and 0.83 MPa, respectively, meeting the standards outlined for indoor‐use plywood (≥0.98 MPa). Mechanistic studies indicated that the adhesion mechanism of such PSM‐based adhesives might involve high solid content, low viscosity, high thermal stability, and the formulation of covalent bonds and hydrogen bond networks.

Abstract
Brown trout is a species complex (Salmo trutta complex, L., 1758) including both widespread invasive (non‐native hatchery strains) lineages and endangered local‐endemic lineages, among which is the Sardinian trout, the only native salmonid present in Sardinia. Multiple stressors (e.g. the spread of stocked brown trout of Atlantic origin, habitat alteration and climate change) combine to seriously threaten the persistence of wild native populations.
In this study, the origin, population genetics and demography of wild Sardinian brown trout populations were extensively investigated. A total of 274 trout individuals collected from 12 hydro‐geographical basins were analysed using both mitochondrial (control region) and nuclear (LDH‐C1* locus and 10 microsatellites) markers.
Although stocking activities have altered the native genetic makeup of some populations in the study area, several (almost) uncontaminated populations showing strong genetic structure were detected. Eroded intra‐population diversity, as well as small effective population size, sometimes associated with a bottleneck signal was also found.
The genetic characteristics of Sardinian trout populations described in this study are probably due, at least partly, to the peculiarity of local environmental conditions at the margin of the ecological niche for salmonids.
Based on the results of this study, the need for urgent measures of conservation aimed to ensure the near future viability of the last wild Sardinian trout populations was discussed.
From posts to protection: Ethical considerations regarding forensic psychiatrists and a duty to warn based on social media

AbstractIncreasing use of social media in forensic mental health evaluations will lead to new challenges that must be resolved by forensic practitioners and the legal system. One such dilemma is the discovery of information that would typically trigger a legal duty and professional ethics obligation for mental health professionals to breach doctor‐patient confidentiality to promote public safety and prevent harm to vulnerable third parties. Although the law and professional organizations offer clear guidance for practitioners in the treatment role, there is currently no clarity from the law or instruction from professional organizations on what mental health professionals should do if they discover such information during a confidential forensic evaluation. For example, a forensic evaluator may find evidence on social media of an evaluee’s threats to seriously harm others, abuse of children and the elderly, or severely impaired driving. There are no clear guidelines for how a forensic psychiatrist should respond in these complicated situations. We review the legal concepts and historical evolution of confidentiality, privilege, and mandated reporter duties that forensic practitioners should consider in these legally ambiguous situations. Finally, we discuss ethics frameworks practitioners can implement to determine their most ethical course of action when faced with such dilemmas.

AbstractHalophilic organisms have adapted to multi‐molar salt concentrations, their cytoplasmic proteins functioning despite stronger attraction between hydrophobic groups. These proteins, of interest in biotechnology because of decreasing fresh‐water resources, have excess acidic amino acids. It has been suggested that conformational fluctuations – critical for protein function – decrease in the presence of a stronger hydrophobic effect, and that an acidic proteome would counteract this decrease. However, our understanding of the salt‐ and acidic amino acid dependency of enzymatic activity is limited. Here, using solution NMR relaxation and molecular dynamics simulations for in total 14 proteins, we show that salt concentration has a limited and moreover non‐monotonic impact on protein dynamics. The results speak against the conformational‐fluctuations model, instead indicating that maintaining protein dynamics to ensure protein function is not an evolutionary driving force behind the acidic proteome of halophilic proteins.

AbstractAlthough radiotherapy is the most effective treatment modality for brain tumors, it always injures the central nervous system, leading to potential sequelae such as cognitive dysfunction. Radiation induces molecular, cellular, and functional changes in neuronal and glial cells. The hippocampus plays a critical role in learning and memory; therefore, concerns about radiation‐induced injury are widespread. Multiple studies have focused on this complex problem, but the results have not been fully elucidated. Naked mole rat brains were irradiated with 60Co at a dose of 10 Gy. On 7 days, 14 days, and 28 days after irradiation, hippocampi in the control groups were obtained for next‐generation sequencing. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were subsequently performed. Venn diagrams revealed 580 differentially expressed genes (DEGs) that were common at different times after irradiation. GO and KEGG analyses revealed that the 580 common DEGs were enriched in molecular transducer activity. In particular, CACNA1B mediated regulatory effects after irradiation. CACNA1B expression increased significantly after irradiation. Downregulation of CACNA1B led to a reduction in apoptosis and reactive oxygen species levels in hippocampal neurons. This was due to the interaction between CACNA1B and Nrf2, which disturbed the normal nuclear localization of Nrf2. In addition, CACNA1B downregulation led to a decrease in the cognitive functions of naked mole rats. These findings reveal the pivotal role of CACNA1B in regulating radiation‐induced brain injury and will lead to the development of a novel strategy to prevent brain injury after irradiation.

Published: February 2024

AbstractWith alkyl halides (I, Br, Cl) as a coupling partner, an electrochemically driven strategy for para‐selective C(sp2)−H alkylation of electron‐deficient arenes (aryl esters, aldehydes, nitriles, and ketones) has been achieved to access diverse alkylated arenes in one step. The reaction enables the activation of alkyl halides in the absence of sacrificial anodes, achieving the formation of C(sp2)‐C(sp3) bonds under mild electrolytic conditions. The utility of this protocol is reflected in high site selectivity, broad substrate scope, and scalable.

Published: February 2024

AbstractHeterocycles that pair main group elements and nitrogen are extremely important within the π‐conjugated heterocycles research community. Compared to the vast number of boron‐nitrogen heterocycles, those that include phosphorus are less common. Furthermore, the use of phosphorus‐nitrogen triple bonds of any type to prepare such compounds is unprecedented. Here, we pair pyridyl hydrazonide ligands with phosphadiazonium cations and demonstrate that the chelated Mes*NP group is directly implicated in the photophysical and redox properties observed for the resulting heterocycles. In doing so, we introduce a novel building block for the production of phosphorus‐containing heterocycles that could find use in small molecule activation and catalysis or as the functional component of emerging organic electronics.
Environmental corporate social responsibility and green dynamic capability: The moderating role of slack resources
Authors: Saleem Shaham , Bashir Hafsa 
Published: February 2024

AbstractBusinesses are struggling to gain a competitive edge by ensuring the success of ecologically friendly products. However, a notable deficiency exists in the current body of research on how organizations can improve their green dynamic capabilities and gain a competitive edge. Companies may increase their competitive advantage by actively participating in environmental corporate social responsibility activities. Therefore, this study examines the role of environmental corporate social responsibility (ECSR) in developing green dynamic capabilities (GDC), leading to green product success (GPS) and competitive advantages. Moreover, the moderating role of slack resources (SRC) is examined between ECSR and GDC. This study applied partial least squares structural equation modeling for empirical examinations by gathering data from 375 manufacturing sector managers. The outcomes explained that ECSR favorably affects GDC, and in turn, GDC positively influences GPS and competitive advantages. Moreover, the outcomes also revealed that SRC moderates the positive relationship between ECSR and GDC. The results have significant practical consequences for businesses. Companies should prioritize ECSR since it helps improve ecological efficiency and boosts the company's green capabilities and long‐term viability. Therefore, businesses need to include their GDC in their product creation processes to maintain a competitive advantage in the growing consumer market that places a high value on ecological sustainability.

AbstractObjectiveNonresponsive parental feeding practices are associated with poorer appetite self‐regulation in children. It is unknown whether this relationship extends beyond childhood to be prospectively associated with the onset of eating disorder (ED) symptoms in adolescence. This exploratory study therefore investigated prospective associations between early childhood parental feeding practices and adolescent ED symptoms and disordered eating behaviors.MethodsData were from two population‐based cohorts with harmonized measures: Generation R (Netherlands; n = 4900) and Gemini (UK; n = 2094). Parents self‐reported their pressure to eat, restriction and instrumental feeding (i.e., using food as a reward) at child age 4–5 years. Adolescents self‐reported their compensatory behaviors (e.g., fasting, purging), binge‐eating symptoms, restrained eating, uncontrolled eating, and emotional eating at 12–14 years. Associations between feeding practices and ED symptoms were examined separately in each cohort using generalized linear models.ResultsIn Gemini, pressure to eat in early childhood was associated with adolescents engaging in compensatory behaviors. In Generation R, parental restriction was associated with adolescents engaging in compensatory behaviors, restrained eating, uncontrolled eating, and emotional eating. Instrumental feeding was associated with uncontrolled eating and emotional eating in Generation R.DiscussionNonresponsive parental feeding practices were associated with a greater frequency of specific ED symptoms and disordered eating in adolescence, although effect sizes were small and findings were inconsistent between cohorts. Potentially, the cultural and developmental context in which child–parent feeding interactions occur is important for ED symptoms. Further replication studies are required to better understand parents' role in the development and maintenance of ED‐related symptoms.Public SignificanceProspective research examining how early childhood parental feeding practices might contribute to adolescent ED symptoms is limited. In two population‐based cohorts, nonresponsive feeding practices (restriction, instrumental feeding, pressure to eat) predicted increased frequency of some ED symptoms and disordered eating behaviors in adolescence, although associations were small and further replication is required. Findings support the promotion of responsive feeding practices, which may benefit young children's developing relationship with food.
Time to revisit the definition of atypical anorexia nervosa
Authors: Golden Neville H. , Walsh B. Timothy 
Published: February 2024

AbstractIn this special issue, international researchers investigate how atypical anorexia nervosa (atypical AN) differs from anorexia nervosa (AN) and other eating disorders with respect to demographics, psychological and physiological morbidity, as well as treatment course and outcome. Manuscripts in this special issue report that atypical AN is associated with substantial medical and psychological morbidity, and the majority of studies find few differences between atypical AN and AN. While much remains to be learned about the long‐term course and treatment response of individuals with atypical AN to psychological and pharmacological interventions, the evidence supports conceptualization of atypical AN as part of a spectrum‐based restrictive eating disorder. These findings together with the potentially stigmatizing use of the term “atypical” suggest it may be time to revise the existing definition of atypical AN.

AbstractTuatara are the sole extant species in the reptile order Rhynchocephalia. They are ecologically and evolutionarily unique, having been isolated geographically for ~84 million years and evolutionarily from their closest living relatives for ~250 million years. Here we report the tuatara gut bacterial community for the first time. We sampled the gut microbiota of translocated tuatara at five sanctuaries spanning a latitudinal range of ~1000 km within Aotearoa New Zealand, as well as individuals from the source population on Takapourewa (Stephens Island). This represents a first look at the bacterial community of the order Rhynchocephalia and provides the opportunity to address several key hypotheses, namely that the tuatara gut microbiota: (1) differs from those of other reptile orders; (2) varies among geographic locations but is more similar at sites with more similar temperatures and (3) is shaped by tuatara body condition, parasitism and ambient temperature. We found significant drivers of the microbiota in sampling site, tuatara body condition, parasitism and ambient temperature, suggesting the importance of these factors when considering tuatara conservation. We also derived a ‘core’ community of shared bacteria across tuatara at many sites, despite their geographic range and isolation. Remarkably, >70% of amplicon sequence variants could not be assigned to known genera, suggesting a largely undescribed gut bacterial community for this ancient host species.

Published: February 2024

AbstractSince the development of the chemistry and applications of boron dipyrromethene dyes (BODIPYs), numerous other platforms based on boron complexes of N‐donor ligands have emerged as molecular optoelectronic materials. By tailoring the structure of the ligand bound to boron, the optical and electronic properties of a compound can be precisely tuned for unique properties, such as aggregation‐induced emission (AIE) in the case of boron difluoride hydrazones (BODIHYs). We examine the impact of modifying the typical bidentate hydrazone ligand structure used to prepare BODIHYs to enable a tridentate coordination mode to produce boron complexes of tridentate acyl pyridylhydrazones. This change allows for the use of arylboronic acids as sources of boron and facilitates the inclusion of complex organic components at the boron centre, including the formation of dye‐dye conjugates. The synthesized compounds exhibit distinct optical and electronic properties when compared to BODIHYs, such as reversible electrochemical reduction and up to a >300 nm pseudo‐Stokes shift in the solid state, all of which were supported by density functional theory calculations.

AbstractThe present study focused on the quantitative determination of active compounds, antioxidant and antibacterial activities of leaf extracts of different Sonneratia species. The tested species including Sonneratia alba (SA), Sonneratia caseolaris (SC), and Sonneratia ovata Backer (SO) were collected from Can Gio Mangrove Forest, Vietnam. The methanol extract of SA leaves was found to contain the highest content of total flavonoids, total phenolics and gallic acid (4344.16 ± 51.78 μg/g dry mass). The highest luteolin‐7‐O‐glucoside and luteolin amounts (5963.28 ± 59.77 and 234.33 ± 10.41 μg/g dry mass, respectively) were found in the methanol extract of SC leaves according to HPLC‐DAD analysis. The methanol extracts of all three species exhibited strong DPPH radical scavenging activity while the ethanol extracts provided strong antibacterial activity against Staphylococcus aureus, Salmonella typhimurium, and Escherichia coli. By fractionating the extracts over a SiO2 column using CHCl3: EA: MeOH gradients, the fractions containing high purity luteolin and luteolin‐7‐glucoside from SC and high purity luteolin from SO were collected. Moreover, all fractions demonstrated significant DPPH free radical scavenging ability but the fraction enriched in gallic acid showed the highest activity. These findings show that SA is a promising source of gallic acid while SC can be potentially used for the extraction and isolation of luteolin‐7‐glucoside.
Adaptive unscented Kalman filter methods for identifying time‐variant parameters via state covariance re‐updating
Authors: Zhang Yanzhe , Ding Yong , Bu Jianqing , Guo Lina 
Published: February 2024

AbstractThe conventional parameter identification process generally assumes that parameters remain constant. However, under extreme loading conditions, structures may exhibit nonlinear behavior, and parameters could demonstrate time‐variant characteristics. The unscented Kalman filter (UKF), as an efficient online recursive estimator, is widely used for identifying parameters of nonlinear systems. Nevertheless, it exhibits limitations when attempting to identify time‐variant parameters. To address this issue, this paper proposes a covariance matching technique that produces an array of adaptive UKF algorithms. Firstly, the sensitivity parameterηis defined to identify the instant when the parameter change occurs, and its threshold is calculated based on the sensitivity parameter time history curve. Secondly, an adaptive forgetting factor is introduced to simultaneously update the innovation, cross, and state covariance matrices when thekth‐step sensitive parameter surpasses the threshold. Finally, a secondary correction forgetting factor (SCFF) is employed to further re‐update the state covariance values at the identified damage locations. This creative step enhances the adaptive capability and optimizes the identification accuracy of the proposed algorithms. Both the numerical simulations and shaking table test demonstrate that the proposed adaptive algorithms can efficiently identify the time‐variant stiffness‐type parameters, and accurately capture their time‐variant characteristics.
