Cholesterol Decorated Diazocine Gelator with Photo‐ and Thermo‐Responsive Properties for Smart Window
Authors: Wang Yaxin , Yuan Yuan , Zhang Shuaipeng , Chen Long , Chen Yulan 
Published: August 2024

Comprehensive SummaryA new gelator (BAzo‐Chol) comprising a diazocine core and two cholesterol units linked via carbamate groups has been designed and synthesized. Its gelation ability in several kinds of organic solvents is identified. Investigations with scanning electron microscopy (SEM), transmission electron microscopy (TEM), rheological measurements, and UV‐vis absorption and 1H NMR spectroscopy reveal that BAzo‐Chol can self‐assemble into elastically interpenetrating one‐dimensional nanostructures in organogels through a cooperative effect of the π‐π interactions, hydrogen‐bonding, and van der Waals forces. Moreover, the unconventional Z/E conformational transitions of these organogels, due to the inclusion of diazocine, endow the BAzo‐Chol gels with excellent photo‐responsive gel‐sol transition and remarkable visible light‐induced chromic properties. Lastly, due to its sensitive response to visible light accompanied by distinct changes in both colour and transparency of the gel‐sol transitions, the potential application of the current gelator in smart windows is signified.
Designing V Single Atom Embedded Carbon Moiety for the Electrocatalytic Nitrogen Reduction Reaction by First Principles Study
Authors: Sahoo Suman Kalyan , Brinck Tore 
Published: August 2024

AbstractDevelopment of an efficient electrocatalyst for the nitrogen reduction reaction (NRR) to serve as a sustainable alternative to the Haber‐Bosch process has proven highly challenging. Single atom catalysts (SACs), which have the maximum atom utilization efficiency, are among the most promising candidates. Single atoms can be incorporated to a catalytic system by doping or substitution or by attaching a molecular coordination complex to a substrate and the different insertion modes allow the chemical environment to be varied. We have used DFT to investigate vanadium SACS for NRR activity with a focus on varying the coordination environment of the V atom. Phthalocyanine, porphyrin and graphene like coordination environments with varying N‐coordination have been studied. Vanadium phthalocyanine (VphN4) is the most promising of the investigated systems. It features high selectivity relative the HER reaction and relatively strong binding of N2 relatively H, which prevents poisoning of the surface by hydrogen. VphN4 also has the lowest overpotential among the studied systems. The electrocatalytic properties of VphN4 deposited as a monolayer on the Ag (111) surface have been investigated. This system, which already has been prepared, shows promising properties for use as a catalytic electrode for the NRR reaction.

ABSTRACTBackgroundNarrative exposure therapy (NET) has shown promising outcomes for treating posttraumatic stress disorder (PTSD) in refugees and veterans. Its effectiveness in patients with PTSD following childhood trauma is, however, still unknown.AimsWe investigated whether NET is an effective treatment for patients with PTSD following childhood trauma.MethodWe studied treatment outcomes of nine adult patients in an outpatient setting. An AB single‐case series design was used with a baseline of 4 weeks prior to treatment. Participants filled in weekly online questionnaires to assess their PTSD symptoms (using the Posttraumatic Diagnostic Scale [PDS]) and their experienced quality of life (using the Manchester Short Assessment of Quality of Life [MANSA]). Data were analysed visually and using a mixed‐effect model.ResultsResults revealed no significant reduction of PTSD symptoms during NET treatment, nor an increase in quality of life, as compared to baseline.ConclusionsThe results of our study do not underscore the effectiveness of NET treatment for patients with PTSD following childhood trauma. Further research is needed to study the effectiveness of NET in this population.

ABSTRACTIntroductionBipolar disorder is a severe mental health problem with limited treatment success. There is a call for improving interventions, requiring an increased understanding of factors driving mood instability. One promising avenue is to study temporal associations between factors that appear relevant according to the emotional amplifier model of Holmes are changes in mood, anxiety and mental imagery.MethodsThe current study used data from a recent RCT for a secondary analysis which applied a network analysis approach to explore temporal associations between weekly measurements of mania, depression, anxiety and mental imagery measured during 32 weeks in two randomised groups (N = 55) receiving either imagery‐focused cognitive therapy (ImCT) or group psychoeducation (PE).ResultsBoth negative intrusive mental imagery and anxiety appeared central in the network analyses, driving changes in both mania and depression, but only in the PE group. In the ImCT group, only anxiety was driving changes in mania and depression.ConclusionAlthough exploratory, findings suggest that prior increases in anxiety and negative intrusive mental imagery might be associated with subsequent increases in depression and mania symptoms in patients with bipolar disorder. Anxiety might in turn increase negative intrusive imagery and associated negative emotions. Although more research is needed, results are in line with the emotional amplifier model and stress that future interventions with a focus on anxiety and imagery might help to improve psychosocial therapies for patients with bipolar disorder. In addition, this study suggests that a network approach is a helpful and feasible way to study mood instability, anxiety and mental imagery to increase our understanding of mechanisms underpinning mood instability.

Published: August 2024

AbstractGeoffroy's cat (Leopardus geoffroyi) is a small‐sized felid native to South America. Given the species' distribution covering a wide variety of habitats, and the presence of high levels of anthropization in part of its range, it is possible that genetically differentiated groups exist and that they occupy different climatic niches. We assessed patterns of contemporary genetic diversity and structure in the species across most of its range, characterizing each inferred genetic group based on ecological niche models. We genotyped 11 microsatellites for 142 samples covering most of Geoffroy's cat distribution, and investigated patterns of genetic structure and diversity, applying spatial and nonspatial Bayesian clustering methods and a spatial principal component analysis. We created ecological niche models for each genetic cluster, evaluating whether these clusters occupy different climatic spaces and display differences in the suitability of different values of the climatic variables analyzed. We identified two genetic clusters, one in the north‐northeast and the other in the south‐southwest of the species' distribution. These clusters showed moderate FST values between them and differences in dispersal/genetic diversity. We found isolation‐by‐distance patterns globally and within each cluster. We observed lower expected heterozygosity compared with other studies and a north–south gradient in allelic richness. The southern cluster showed lower genetic variability and a more restricted climatic niche suggesting that this group is more vulnerable to the effects of the current context of climate change. Individuals from the southern genetic cluster are under different pressures, likely a product of the particularly dry habitat they occupy. Climatic variables associated with habitat suitability suggest the southern cluster has affinity for the arid and semiarid conditions present in its distribution. Conservation measures should consider the genetic structure observed and differences in climatic spaces to maintain the evolutionary potential of the species.

Published: August 2024

AbstractAn efficient Pd(II)‐catalyzed remote selective cross‐dehydrogenative coupling of broadly useful synthetic building blocks biphenyl Weinreb amides with carboxylic acids is developed. This acetoxylation protocol is performed under room temperature using N‐fluorobenzene‐sulfonimide (NFSI) as the oxidant, exhibiting a wide range of functional group tolerance and affording δ‐position‐ selective products up to 85 % yield. Notably, a diverse set of carboxylic acid‐containing drugs is also found to be compatible under the current reaction conditions. Preliminary mechanistic studies indicate that this reaction presumably proceeds through a seven‐membered palladacycle intermediate.

AbstractBackgroundWith the development of endoscopic imaging, superficial pharyngeal squamous cell carcinoma can now be detected during routine endoscopy. Recently, the effectiveness of endoscopic resection for superficial pharyngeal squamous cell carcinoma have been reported.MethodsThis study had a retrospective single‐center design that included patients with superficial pharyngeal squamous cell carcinoma who underwent endoscopic resection. A total 47 patients with 53 lesions were analyzed.ResultsEn bloc and R0 resection rates were 83.0% and 56.6%. Local recurrence and cervical lymph node metastasis (CLNM) were detected in 1 and 3 patients during follow‐up. The macroscopic type 0‐I was an independent factor for CLNM. The 3‐year cumulative incidence of metachronous pharyngeal squamous cell carcinoma following endoscopic resection was 33.0%, and the 5‐year overall survival rate was 89.2%.ConclusionsEndoscopic resection is an effective treatment for superficial pharyngeal squamous cell carcinomas, and the macroscopic type 0‐I is a useful predictor of CLNM.

Published: August 2024

AbstractSodium metal, with a high theoretical specific capacity (∼1165 mA h g−1) and a low redox potential (−2.71 V vs. SHE) as well as low cost, becomes an attractive option for high‐energy‐density sodium secondary batteries. However, the practical application of sodium metal anodes is hindered by dendrite growth, which results in low energy efficiency, poor lifetime and serious safety issues. To address this challenge, researchers propose various strategies, including the formation of sodium alloys (Na‐M alloys, M = Sn, Sb, Bi, In, etc.) through alloying reaction. The alloying effect has a positive impact in terms of reducing the local current density, mitigating the volume expansion, and inhibiting the dendrite growth. It is thus an effective solution for constructing high‐performance sodium secondary batteries. This review systematically describes the mechanism of dendrite growth and the alloying process of Na‐M alloys, summarizes recent research progress and strategies for applying Na‐M alloys to create dendrite‐free sodium secondary batteries, as well as presents prospects for the development of Na‐M alloys and offers clear suggestions for future research. This review aims to inspire further efforts to build dendrite‐free, high‐performance sodium secondary batteries and broaden a new aspect for the next‐generation battery systems.

How well do 3D‐printed tissue mimics represent the complex mechanics of biological soft tissues? An example study with Stratasys' cardiovascular TissueMatrix materials
Authors: Bechtel Grace N. , Kostelnik Colton J. , Rausch Manuel K. 
Published: August 2024

AbstractTissue mimicking materials are designed to represent real tissue in applications such as medical device testing and surgical training. Thanks to progress in 3D‐printing technology, tissue mimics can now be easily cast into arbitrary geometries and manufactured with adjustable material properties to mimic a wide variety of tissue types. However, it is unclear how well 3D‐printable mimics represent real tissues and their mechanics. The objective of this work is to fill this knowledge gap using the Stratasys Digital Anatomy 3D‐Printer as an example. To this end, we created mimics of biological tissues we previously tested in our laboratory: blood clots, myocardium, and tricuspid valve leaflets. We printed each tissue mimic to have the identical geometry to its biological counterpart and tested the samples using identical protocols. In our evaluation, we focused on the stiffness of the tissues and their fracture toughness in the case of blood clots. We found that the mechanical behavior of the tissue mimics often differed substantially from the biological tissues they aim to represent. Qualitatively, tissue mimics failed to replicate the traditional strain‐stiffening behavior of soft tissues. Quantitatively, tissue mimics were stiffer than their biological counterparts, especially at small strains, in some cases by orders of magnitude. In those materials in which we tested toughness, we found that tissue mimicking materials were also much tougher than their biological counterparts. Thus, our work highlights limitations of at least one 3D‐printing technology in its ability to mimic the mechanical properties of biological tissues. Therefore, care should be taken when using this technology, especially where tissue mimicking materials are expected to represent soft tissue properties quantitatively. Whether other technologies fare better remains to be seen.
Bridging health self‐efficacy and patient engagement with patient‐centered culturally sensitive health care for Black American adults

Published: August 2024

AbstractThis study investigates whether systems‐level interventions, specifically patient‐centered culturally sensitive health care (PC‐CSHC) from healthcare providers, office staff, and the clinic environment, moderate the relationship between health self‐efficacy and patient engagement among Black American adults. An online survey was completed by 198 Black American adults. PC‐CSHC from healthcare providers, office staff, and the clinic environment did not mitigate the adverse effects of low health self‐efficacy on patient engagement. However, PC‐CSHC from healthcare providers (b = 0.38) was as significant as health self‐efficacy (b = 0.37) in predicting patient engagement, R2 = 0.47, F(9, 177) = 19.61, p < 0.001. Provider‐delivered PC‐CSHC can enhance patient engagement among Black American adults. This systems‐level approach has the potential to reach more patients than intrapersonal interventions alone and alleviates the undue burden placed on Black Americans to leverage intrapersonal strengths in the face of health disparities rooted in structural racism.

Published: August 2024

AbstractBackgroundSarcopenia is an age‐related muscle disease that increases the risk of falls, disabilities, and death. It is associated with increased muscle protein degradation driven by molecular signalling pathways including Akt and FOXO1. This study aims to identify genes, gene interactions, and molecular pathways and processes associated with muscle aging and exercise in older adults that remained undiscovered until now leveraging on an artificial intelligence approach called artificial neural network inference (ANNi).MethodsFour datasets reporting the profile of muscle transcriptome obtained by RNA‐seq of young (21–43 years) and older adults (63–79 years) were selected and retrieved from the Gene Expression Omnibus (GEO) data repository. Two datasets contained the transcriptome profiles associated to muscle aging and two the transcriptome linked to resistant exercise in older adults, the latter before and after 6 months of exercise training. Each dataset was individually analysed by ANNi based on a swarm neural network approach integrated into a deep learning model (Intelligent Omics). This allowed us to identify top 200 genes influencing (drivers) or being influenced (targets) by aging or exercise and the strongest interactions between such genes. Downstream gene ontology (GO) analysis of these 200 genes was performed using Metacore (Clarivate™) and the open‐source software, Metascape. To confirm the differential expression of the genes showing the strongest interactions, real‐time quantitative PCR (RT‐qPCR) was employed on human muscle biopsies obtained from eight young (25 ± 4 years) and eight older men (78 ± 7.6 years), partaking in a 6‐month resistance exercise training programme.ResultsCHAD, ZDBF2, USP54, and JAK2 were identified as the genes with the strongest interactions predicting aging, while SCFD1, KDM5D, EIF4A2, and NIPAL3 were the main interacting genes associated with long‐term exercise in older adults. RT‐qPCR confirmed significant upregulation of USP54 (P = 0.005), CHAD (P = 0.03), and ZDBF2 (P = 0.008) in the aging muscle, while exercise‐related genes were not differentially expressed (EIF4A2 P = 0.99, NIPAL3 P = 0.94, SCFD1 P = 0.94, and KDM5D P = 0.64). GO analysis related to skeletal muscle aging suggests enrichment of pathways linked to bone development (adj P‐value 0.006), immune response (adj P‐value <0.001), and apoptosis (adj P‐value 0.01). In older exercising adults, these were ECM remodelling (adj P‐value <0.001), protein folding (adj P‐value <0.001), and proteolysis (adj P‐value <0.001).ConclusionsUsing ANNi and RT‐qPCR, we identified three strongly interacting genes predicting muscle aging, ZDBF2, USP54, and CHAD. These findings can help to inform the design of nonpharmacological and pharmacological interventions that prevent or mitigate sarcopenia.
