Published: January 2023

AbstractWe investigated the interfacial adhesion of immiscible component polymers of isoprene rubber (IR) and α‐olefin copolymer (αOC) by chemical reaction using peroxide crosslinking agent which was used for the crosslinking of IR. Fibrillar structure of the IR elongated from the αOC domains was observed by scanning electron microscope and the tensile stress of the IR was enhanced without sacrifice of the excellent elongation in the two‐phase blends of IR and αOC obtained after crosslinking reaction, suggesting that adhesion exists at the interface. The confocal‐Raman imaging of the bilayer films of IR and αOC revealed that mixed layer having a distance about 358 nm was formed at the interface by the chemical reaction. Owing to the existence of the mixed layer at the interface, the adhesion strength was larger as the mixed layer at the interface was thicker. Thus interfacial adhesion exists in the immiscible component polymers of IR and αOC by the chemical reaction and the tensile stress was enhanced without sacrifice of the excellent elongation.

Published: January 2023

AbstractBy increasing technical demand for long‐lasting and safer batteries against thermal explosion, garnet‐type cubic phase Li7La3Zr2O12 (LLZO) is a promising solid electrolyte as a next‐generation advanced battery. In this work, we studied Al and Nb co‐doped Li6.25–yAl0.25La3Zr2–yNbyO12 (0 ≤ y ≤ 0.30) electrolytes prepared using a modified sol–gel method. X‐ray diffraction and electrochemical analyses probed the synergistic effect of Al and Nb simultaneous substitution on the microstructure and ionic conductivity. In conclusion, an optimal amount of Al and Nb enhances densification and ionic conductivity, and then Li6Al0.25La3Zr1.75Nb0.25O12 achieves the highest relative density of 94% and total ionic conductivity of 5.41 × 104 S cm−1 at 30°C.

AbstractNa+ superionic conductor (NASICON)‐structured Na4VMn(PO4)3 (NVMP) possesses stable cycling performance at 2.5–3.8 V by replacing V with lower cost Mn but suffers rapid capacity decay when further widening the voltage to 2.5–4.2 V, owing to a less stable V4+/V5+ redox couple. Herein, to stabilize the V4+/V5+ couple and improve the reversibility, a series of carbon‐coated NVMP (NVMP@C) with different V/Mn ratios are compared, among which, Na3.25V1.75Mn0.25(PO4)3@C delivers an additional reversible V4+/V5+ capacity of 7 mAh g−1 at the voltage of 3.9–4.2 V. Based on this, to further activate the capacity of V4+/V5+, Al‐doped Na3.25V1.75−yMn0.25Aly(PO4)3 structures are synthesized. When 0.5 Al is doped, 15 mAh g−1 capacity corresponding to V4+/V5+ can be released. In addition, it is found that the activation of V4+/V5+ is not conducive to electrochemical reversibility and C‐rate performance, owing to the shrinkage of the whole framework structure with the oxidization of V4+ to V5+.

AbstractThis study aimed to identify ideal sites for botulinum toxin injection by analyzing the intramuscular nerve patterns of the triceps brachii muscles. A modified Sihler's method was applied to the triceps brachii muscle (15 specimens), with long, medial, and lateral heads. The intramuscular arborization areas of the long, medial, and lateral heads of the triceps brachii muscle were measured as a percentage of the total distance from the midpoint of the olecranon (0%) to the anteroinferior point of the acromion (100%), by dividing the medial and lateral parts based on the line connecting the midpoint of the olecranon and the anteroinferior point of the acromion. Intramuscular arborization patterns were observed at the long head at two medial regions, proximally 30%–50% and distally 60%–70%; medial head of 30%–40%; and lateral head of 30%–60%. These results suggest that the treatment of spasticity of the triceps brachii muscles involves botulinum toxin injections in specific areas. The areas corresponding to the areas of maximum arborization are recommended as the most effective and safe points for botulinum toxin injection.

AbstractChevrel phases consisted of abundant materials, are of great interest in a variety of energy conversion and storage technologies because of unique structural and electronic features. Herein, crystalline Mn2Mo6S8, Fe2Mo6S8 and Cu2Mo6S8 Chevrel phases with cubic shapes and homogeneous atomic distribution have been synthesized by solid state method and characterized by advanced analytical techniques. These Chevrel phase catalysts have been investigated for the photocatalytic hydrogen evolution in eosin‐Y and triethanolamine media as sensitizer and sacrificial agent, respectively, under visible light irradiation. Mn2Mo6S8 showed the highest photocatalytic hydrogen evolution activity, which is 2.5‐fold and 3‐fold greater than that of Fe2Mo6S8 and Cu2Mo6S8, respectively. The photocatalytic activity differences of Chevrel phase catalysts can be explained by atomic properties of Mn, Fe and Cu metals. Moreover, the antibacterial efficiencies of Mn2Mo6S8, Fe2Mo6S8 and Cu2Mo6S8 have been also examined on Gram‐negative Escherichia coli and Gram‐positive Staphylococcus aureus, as model microorganisms. Accordingly, Mn2Mo6S8 exhibited physical membrane damages such as dents, wrinkled cells and cell elongation and has the most superior antibacterial activity under NIR irradiation.
Large Temperature‐Jump and Nanosecond Hyperquenching for Time‐Resolved Structural Studies
Authors: Cherepanov Alexey V. , Schwalbe Harald 
Published: January 2023

AbstractThe quest for atomic structures of microsecond reaction intermediates is at the frontline of modern biochemistry. Currently, there is a clear lack of experimental methods for preparing necessary time‐resolved samples. Here, we report the development of a single‐turnover technique for nanosecond initiation and suspension of biomolecular reactions with kinetic resolution in the microsecond time domain. Reactions can be started by large temperature‐jump or direct mixing and arrested by hyperquenching in liquid cryogen at a target temperature of 77 K. Diverse morphology of nanoscale glassy bodies feature among others thin field‐of‐view plane sheets that can be used for structure analyses of freeze‐trapped macromolecules by transmission electron cryomicroscopy. We also report the ultra‐high vacuum sublimation at 77 K – a novel method for concentrating reaction intermediates for structural studies by low‐temperature techniques.

AbstractBackgroundTo evaluate the psychosocial consequences of surveillance with whole‐body MRI (WB‐MRI) in individuals with the heritable TP53‐related cancer (hTP53rc) syndrome, also known as the Li‐Fraumeni syndrome, with regard to cancer worry, perceived benefits and risks to surveillance and overall health.Patients and methodsSince 2016, the national Swedish TP53 Study (SWEP53) has offered surveillance with WB‐MRI to all individuals with hTP53rc syndrome. Seventy‐five individuals have been included in the study. Sixty consecutive participants fulfilled a base‐line evaluation as well as an evaluation after 1 year with structured questionnaires including the Cancer Worry Scale (CWS), perceived benefits and risks of surveillance, and the 36‐item Short Form Survey (SF‐36). Individuals with or without previous personal cancer diagnosis were enrolled and results at baseline and after 1 year of surveillance were compared. For SF‐36, a comparison with the normal population was also made.ResultsParticipants with previous cancer tend to worry more about cancer, but both individuals with and without cancer had a positive attitude toward surveillance with no differences regarding perceived benefits and barriers to surveillance. Participants with a previous cancer scored significantly lower on some of the SF‐36 subscales, but between‐group differences were found only for social functioning after 1 year.ConclusionsSurveillance with WB‐MRI is feasible from a psychosocial point of view both among TP53 carriers with as well as without a previous history of cancer and does not increase cancer worry in any of the groups.Plain language summary

Individuals with heritable TP53‐related cancer syndrome (also known as the Li‐Fraumeni syndrome) have a high lifetime risk of developing cancer.

These TP53 carriers are offered surveillance with whole‐body MRI to detect cancer early. There are few reports of the psychosocial impact of surveillance.

In this study, we wanted to evaluate cancer worry, benefits and barriers to participation, and perceived overall health.

Our study shows no increase in cancer worry after 1 year of surveillance, regardless of previous cancer.

Published: January 2023

AbstractThe primary cause for cancer‐related death is metastasis, and although this phenomenon is the hallmark of cancer, it remains poorly understood. Since studies on the underlying mechanisms are still demanding by experimental means prognostic tools based on computer models can be of great value, not only for elucidating metastasis formation but also for assessing the prospective benefits as well as risks of a therapy for patients with advanced cancer. Here, we present an agent‐based model (ABM), describing the complete process of platelet‐assisted extravasation of circulating tumor cells (CTCs) from the chemoattraction of blood platelets by the CTCs up to the embedding of the CTCs in the epithelial tissue by computational means. From the simulation results, we conclude that the ABM produces results in consistency with experimental observations, which opens new perspectives for the development of computer models for predicting the efficacity of drug‐based tumor therapies and assisting precision medicine approaches.
Preparation of Efficient Organic Solar Cells Based on Terpolymer Donors via a Monomer‐Ratio Insensitive Side‐Chain Hybridization Strategy

Published: January 2023

AbstractCreating new donor materials is crucial for further advancing organic solar cells. Random terpolymers have been adopted to overcome shortcomings of regular alternating donor–acceptor (D‐A) polymers of which the performance is often susceptible to batch‐to‐batch variations. In general, the properties and performance of efficient D1‐A‐D2‐A and D‐A1‐D‐A2 terpolymers are sensitive to the D1/D2 or A1/A2 monomer ratios. Side‐chain hybridization is a strategy to address this problem. Here, six D1‐A‐D2‐A‐type random terpolymers comprising D1 and D2 monomers with the same π‐conjugated D unit but with different side chains were synthesized. The side chains, containing either fluorine or trialkylsilyl substituents were chosen to provide near‐identical optoelectronic properties but provide a tool to create a better‐optimized film morphology when blended with a non‐fullerene acceptor. This strategy allows improving the device performance to over 18 %, higher than that obtained with the corresponding D1‐A or D2‐A bipolymers (around 17 %). Hence, side‐chain hybridization is a promising strategy to design efficient D1‐A‐D2‐A terpolymer donors that are insensitive to the D1/D2 monomer ratio, which is beneficial for the scaled‐up synthesis of high‐performance materials.

AbstractBackgroundMammalian calvarium is composed of flat bones developed from two origins, neural crest, and mesoderm. Cells from both origins exhibit similar behavior but express distinct transcriptomes. It is intriguing to ask whether genes shared by both origins play similar or distinct roles in development. In the present study, we have examined the role of Pdgfra, which is expressed in both neural crest and mesoderm, in specific lineages during calvarial development.ResultsWe found that in calvarial progenitor cells, Pdgfra is needed to maintain normal proliferation and migration of neural crest cells but only proliferation of mesoderm cells. Later in calvarial osteoblasts, we found that Pdgfra is necessary for both proliferation and differentiation of neural crest‐derived cells, but not for differentiation of mesoderm‐derived cells. We also examined the potential interaction between Pdgfra and other signaling pathway involved in calvarial osteoblasts but did not identify significant alteration of Wnt or Hh signaling activity in Pdgfra genetic models.ConclusionsPdgfra is required for normal calvarial development in both neural crest cells and mesoderm cells, but these lineages exhibit distinct responses to alteration of Pdgfra activity.
Evaluation and optimization of an eDNA metabarcoding assay for detection of freshwater myxozoan communities

Published: January 2023

AbstractThe environmental DNA (eDNA) metabarcoding approach has become a useful tool for detecting the species diversity of different animal groups, including parasites. Myxozoa (Malacosporea and Myxosporea) represent a unique group of morphologically simplified endoparasites that mainly infest fish and whose diversity remains largely unexplored. Metabarcoding of DNA from the aquatic environment is a promising non‐invasive method that allows us to assess myxozoan biodiversity at a given site. This is essential not only for describing myxozoan communities, but also for the development of disease control methods. Using an alignment of 330 sequences, we employed in silico PCR to score primer pairs, designed to amplify the V4 region of the SSU rDNA of different myxosporean sublineages comprising the entire diversity of oligochaete‐infecting (freshwater) myxosporeans. We selected eight clade‐specific primer sets for metabarcoding, avoiding amplification of DNA from other organisms present in eutrophic freshwaters. The metabarcoding approach used in the analysis of eDNA sediment samples detected a high myxosporean diversity even in small sample volumes (in total 44 OTUs). Furthermore, metabarcoding analysis of myxosporeans in fish tissue samples selected for primer testing revealed 91 different myxosporean OTUs, more than double the number obtained by classical PCR screening and Sanger sequencing with general myxozoan primers and almost seven times higher detection than by microscopic examination. Our results further suggest quantitative sampling requirements for realistic future diversity estimates by comparing OTUs from fish tissue metabarcoding and eDNA samples. The use of specific primer sets enabled the detection of a high proportion of myxosporean reads (63–100%) in all datasets, even in highly eutrophic habitats. This shows our metabarcoding approach as an excellent tool for non‐invasive and sensitive detection of myxosporean biodiversity in aquatic sediments, potentially useful for monitoring myxozoan disease agents that threaten economically important fish in aquaculture.
The method of turbulent transformation of energy
Authors: Ashcheulov Anatoly , Derevianchuk Mykola , Lavreniuk Dmytro 
Published: January 2023

AbstractCurrently, new methods of energy transformation are of interest. The results of the researches in the directions of anisotropic transformation of electric energy show that the existing devices are characterized by a small coefficient of transformation. This is primarily due to the use of unipolar anisotropic materials and the appearance, as a result, in their volumes the electric vortices that are characterized by a laminar flow. This article proposes a new method of energy transformation, which is carried out by means of vortices with turbulent character of flow. According to our studies, such vortices appear in devices working on the basis of bipolar anisotropic materials. Depending on the characteristics of such material, they can be used as generators of electricity, heat, and cold. Their work is based on the transformation of the electric current by the bipolar anisotropic electric conductive medium and their further interaction with the external energy environment. These anisotropic materials in selected crystallographic directions are characterized by different p‐ and n‐types of conductivity providing the presence of ohmic contact between the layers. The leakage of the external electrical current of the sinusoidal form through this rectangular plate causes the appearance in its volume the electric current vortices with turbulent character of the current. For the first time it is shown that such a method of energy transformation is an effective mechanism that transfers energy between the external environment and the anisotropic plate.

AbstractBackground and AimsCytokine profiles of peripheral blood and other bodily fluids provide diagnostic indicators for assessing inflammatory processes. Menstrual effluent may provide a noninvasive source of biological material for monitoring cytokine levels in blood and in endometrial tissues. This pilot study investigated the potential of measuring cytokines in menstrual effluent, and compared the cytokine profiles of menstrual versus peripheral blood.MethodsSeven healthy donors (aged ≥18 and ≤45 years) collected menstrual effluent on day 2 of menses. Matched peripheral blood samples were collected by venous blood draw on the same day. Levels of 62 cytokines were measured in all samples by 62‐plex Luminex assay.ResultsPeripheral blood and menstrual effluent cytokine profiles were tenuously correlated (r2 = 0.26, p < 0.0001), with higher levels detected in menstrual effluent for 48/62 cytokines. Thirty five cytokines were significantly elevated in menstrual effluent compared to peripheral blood samples (IL‐8, CCL2, CCL4, LIF, IL‐1RA, IL‐6, IL‐1β, HGF, CCL3, FGF‐2, TNF‐α, VEGF‐A, IL‐1α, CXCL1, IL‐9, IL‐10, EGF, CXCL5, CSF3, EOTAXIN, TGF‐α, TRAIL, CXCL10, VEGF‐D, IL‐12P40, CXCL9, IL‐18 RESISTIN, IL‐22, IL‐21, CSF1, IFN‐γ, IL‐17A, CXCL12, IL‐12p70). Two cytokines (LEPTIN, CSF2) were expressed at significantly lower levels in menstrual effluent compared to peripheral blood. Linear regression of individual cytokines found low predictive power (linear regression p > 0.05) for 53/62 cytokines in menstrual effluent versus peripheral blood. Levels of TGF‐β (r2 = 0.87, p = 0.002) and CCL7 (r2 = 0.63, p = 0.033) were significantly positively correlated between matched menstrual and peripheral blood samples.ConclusionIn this group of study participants, the cytokine profile of menstrual effluent was quantitatively distinct from peripheral blood, and also characterized by higher levels of inflammatory signaling. This pattern of comparative menstrual blood cytokine profiles points to a need for further studies to evaluate the relationship between peripheral and menstrual blood cytokines in broader populations including both healthy and diseased states.

Published: January 2023

AbstractBackgroundRecent events like the global pandemic and geopolitics leading to war bring to bear the evergreen importance of psychological well‐being (PWB) among workers and how it can further influence business growth and performance. Furthermore, the complexity of today's job requirements has created enormous life pressures for individuals, negatively hurting their PWB.MethodThis article took the format of a literature review of existing research work by pursuing the keywords in the SCOPUS database to retrieve the articles published on PWB in the field of business and economics from 1978 to 2022. The data were analyzed to elaborate, interpret and graphically display the results, in particular, authors, sources, documents, and social structure of the existing bibliography. The Bibliometrix R package is used for robust analysis of retrieved data.ResultsThe findings showed that the last decade saw a rise in scholarly work on PWB. However, in 2021, its sharp expansion stalled. It further revealed that academics from four countries had a significant role in accessing PWB in the business and economics fields, namely the United States, the United Kingdom, Australia, and Canada. The reports also indicate themes such as mental health, coronavirus disease 2019 (COVID‐19), and depression are emerging themes, whereas niche themes include unemployment, quality of life, and job loss.ConclusionThis study suggests these new areas be studied in contemporary literature to provide cogent room to improve policy decisions on PWB within the business world.
