The paper presents the results of the analysis dealing with the impact of plant fertilisation in the first year after planting on the leaf morphological characteristics. The analysis was conducted within the research into the potential introduction and adaptation of paulownia to different sites in Serbia. The results related to the effects of fertilisation on the quality of plant leaves are useful for the cultivation of certain types of soil where the morphometric analysis of leaves reveals structure-function relationships, i.e., more detailed indicators of the species' adaptability. The research was conducted in two localities. Sample plots with Paulownia elongata S. Y. Hu. and Paulownia fortunei Seem. Hemsl. were established in Obrenovac and Pambukovica, where leaf material was collected for laboratory analysis. The following morphometric leaf characteristics were measured: leaf area, leaf perimeter, leaf lamina length, central nerve length, maximum leaf width, leaf width at 1 cm from the base of the leaf, petiole length, distance between the 3rd and 4th nerve, the number of nerves to the left side of the midrib, and the number of veins to the right side of the midrib. The obtained results of leaf morphometric measurements were statistically processed in the Statgraphics software. Based on the results of measuring the leaf morphometric characteristics, fertilisation has a positive effect on the size of the leaves of the studied paulownia species.

Published: January 2023

Organic matter is considered one of the main sources of water pollution caused by the discharge of wastewater of different categories directly into rivers. The increased content of organic matter serves as a source of food for water microorganisms and significantly lowers dissolved oxygen of the recipient. Floating treatment wetlands (FTW) are an innovative green technology that removes excess organic matter from water. This paper shows the effectiveness of floating treatment wetlands in removing organic matter from the water of a polluted urban river. Cells with floating islands had BOD reduced by 84-91%, COD in the range of 57-65% and TOC by 16-20%. The highest efficiency in COD and TOC reduction was achieved in Cell I where P. australis was planted, and BOD in Cell II where C. indica was planted. The results of these studies showed that after 6 days of treatment of polluted water, a high reduction of BOD and COD was achieved, as well as a satisfactory reduction of TOC concentration.

The paper presents the comparative characteristics of the floristic composition in the association of the submontane beech forest (Helleboro odori-Fagetum moesiacae Soo & Borhidi 1960.) and artificially established spruce stands (Picea abies (L.) Karst.) in the area of Kosmaj. According to the obtained results, the cover in the shrub and ground flora layers of the artificially established spruce stands increased significantly compared to the autochthonous beech forests, but the floristic diversity decreased. Regarding the spectrum of floral elements, a higher percentage of mesophilic (51%) and frigophilic plants (11%) was observed in the artificially established spruce stands compared to the beech forests. Significant differences could also be observed regarding the spectrum of life forms since there were twice as many phanerophytes in the artificially established spruce stands (48%) than in the beech forests (23%). This resulted from the open canopy of artificially established spruce stands and the influx of a greater amount of light, which made conditions favourable for an abundant shrub layer to develop in this community. A comparative study of the mean plant indicator values showed that in the artificially established spruce stands, the mean values of the ecological factors for moisture, light and soil nitrogen supply increased, while the value of the ecological factors for temperature and soil acidity decreased compared to the beech forests.

Published: January 2023

In this paper, Soil Protection Coefficient (Xa) was quantified through the approach of high resolution multispectral orthomosaic segmentation and classification. The approach was presented in the example of ski lane in ski center Kopaonik. The data collection was performed through application of Unmanned Aerial System equipped with 5band multispectral sensor and RGB sensor. Data processing was performed with digital photogrammetric and Object Based Image Analyses software. The Soil Protection Coefficient represents the descriptive and very sensitive parameter of Erosion Potential Method. Application of 5 spectral bands, of which 2 bands are very sensitive to the type of land use /land cover allowed precise detection, delineation and classification of different land cover/use types. These types were directly tied to the values of Xa coefficient which were originally proposed by the author of the Erosion Potential Method, professor Slobodan Gavrilović. The final result was a georeferenced digital map classified with both land cover/use and Xa values classes. This approach created the potential to use such maps for further analyses, planning, and modeling of erosion protection measures.

The importance of research on the impact of social networks on the employment is an increasingly current topic for research at the global level. LinkedIn is increasingly present by companies, businesses offering jobs as well as people looking for a business opportunity. The aim of the research was to determine the extent to which the LinkedIn network has an impact on employment in the Republic of Serbia and to investigate the attitudes of users of this network. The survey was conducted from January to March 2022 on a sample of 244 respondents, users of the LinkedIn network. SPSS software was used, 26.00, and the obtained data were analyzed by descriptive statistics. To determine the structure of the questionnaire and the percentage of variance, an exploratory factor analysis was performed together with a higher order factor analysis, in order to obtain the desired number of factors. The authors used multiple regression analysis to confirm the significance of the predictors. The results indicate that the greatest importance is in predicting the use of the Linkedin network when hiring workers and their feelings when using this network. The importance of work is reflected in the recognition of the importance of the social network LinkedIn in hiring workers in order to better recruit professionals.

Published: January 2023

Economic diplomacy as such includes targeted activities carried out by representatives of one country with representatives of another country, which in their core aim to increase foreign investments, greater volume of exports or imports, as well as strengthening the positions of domestic companies in other countries. In addition to the aforementioned activities, economic diplomacy also includes activities that a country undertakes by participating in international economic organizations as well as joining them. This discipline represents the future and the direction of diplomacy of every modern state that wants to survive in today's market conditions, which are unstable, changing and a decisive factor for every participant. The main goal, focus and function of economic diplomacy must be the protection of national economic interests in every international relationship, whatever level it may be. In this paper, economic diplomacy as a discipline will be dealt with, a short theoretical review will be given, as well as the author's perspectives and views on the progress of the Republic of Serbia and the countries of the region in this field.

Published: January 2023

Background/Aims: Endoscopic submucosal dissection (ESD) has been established as a treatment modality for superficial esophageal squamous cell carcinoma (ESCC). Long-term follow-up data are lacking in Western countries. The aim of this study was to analyze long-term survival in a Western center.Methods: Patients undergoing ESD for ESCC were included. The analysis was performed retrospectively using a prospectively collected database.Results: R0 resection rate was 96.7% (59/61 lesions in 58 patients). Twenty-seven patients (46.6%) fulfilled the curative resection criteria (M1/M2) (group A), 11 patients (19.0%) had M3 lesions without lymphovascular invasion (LVI) (group B), and 20 patients (34.5%) had lesions with submucosal invasion or LVI (group C). Additional treatment was recommended after non-curative resection. It was not performed in 20/31 patients (64.5%), mainly because of comorbidities (75%). Twenty-nine out of 58 (50.0%) patients died during a mean follow-up of 3.7 years. Death was related to ESCC in 17.2% (5/29) of patients. The disease-specific survival rate after curative resection was 100%. Overall survival rates after 5 years were 61.5%, 63.6% and 28.1% for groups A, B, and C, respectively. The overall survival was significantly worse after non-curative resection (p=0.038).Conclusions: Non-curative resection is frequent after ESD for ESCC in Western patients. The long-term prognosis is limited and mainly determined by comorbidity. Early diagnosis and pre-interventional assessments need to be improved.
Redefining the Margins: Intertextual and Secondary Characters in Children’s historical novels.
Authors: Angelaki Rosy Triantafyllia
Published: January 2023

The historical novel for children is the kind of Literature that transmits to young readers the historical knowledge in a pleasant and easy way, thanks to its entertaining and recreational character. The fictional heroes in most children's historical novels are social examples for the young readers, who adopt behaviors and motivations through observation. Additionally, the postmodern attestation of History as narration, with the appointment of microhistory - which is favored when the psychography of fictional heroes is on the forthground and when historical facts are interpreted from different perspectives and under various visual angles - spur many writers to provide marginal characters with space as well as speech.
Bearing in mind that the byzantine era is a common subject in Children’s Literature and contemporary novelists try to educate children and at the same time bring out  Byzantium's charm either by highlighting neglected historic events or by examining already known faces and facts from a fresh angle  and given the fact that the concept of intertextuality in literature is a way to build up interpretive communities among young readers, this paper examines Greek writer’s, Penelope Maximos, five historical novels for children entitled as In the years of Alexios Komninos, (Stochastis, 1984), The first crusaders in Byzantium; 1096-1099 AD (Stochastis, 1989), Emmanouil Komninos. The knight emperor (Stochastis, 1990), The downfall of Thessaloniki. In the years of Andronikos Komninos (Stochastis,  1987) and  Close to Athenais (Astir, 1972). More specifically, we will focus on the way Maximos attempted to make “visible” fictional characters  who were until recently considered of less or least importance; Minors and adults who were being oppresed during the Byzantine era, such as slaves, suddenly become protagonists surrounding historic characters and, thanks to their presence, make the plot roll smoothly. In this paper will be also pointed out the way the writer chose to present to young readers female characters and their efforts not only to express their emotions freely, but also to interfere with Byzantine society and fight for their rights, in order to point out to the juvenile readers paths, thoughts and life idealism.
Analysis of Simon Stranger´s novel Lexicon of Light and Darkness
Authors: Mašát Milan
Published: January 2023

The main goal of the paper is to point out the obscure model reader of the publication Lexicon of Light and Darkness by Simon Stranger, and thus substantiate our opinion on certain limits in defining the implicit reader of some texts with the theme of Shoah in relation to their goals. The analysis of the narrative was carried out through a content analysis of a qualitative nature. We work with the intentions of close contextual analysis, which means that we work only with the researched artistic narrative, or with other fiction, which we prove our claims. Prior to the analysis, the following research questions were determined: 1) How does the depiction of the effort to eradicate Jewish nationality differ in Stranger´s publication in comparison with other artistic narratives on the same subject? 2) How is the influence of the social environment on the mental orientation and maturation of the adolescent? 3) What strategies did Stranger choose in relation to the reader? 4) How does the perception of selected aspects of World War II by people living at different times in the context of Stranger´s publication differ? 5) To what extent is the text devoted to space and support for pluralistic interpretation by recipients?
Literary learning: A proposal for using literature for the acquisition of emotional competencies
Authors: Leibrandt Isabella
Published: January 2023

The concept of literary learning is based upon the conception that there are learning processes which through the use of literary texts have a productive result. The linking element between both terms is the development of some competencies, in particular, emotional as well as discursive. By presenting these considerations, new answers to old questions, which are still discussed in the didactics of literature, are provided: Why is literary reading necessary in Foreign Language Teaching (FLT), what goals are being pursued, how should literary reading be directed, and which learning processes are intended? The article deals with the aesthetic experience of literature on the basis of a lesson example. It is aimed at the aesthetic perception whereby not only is a pleasurable reading understood, but also a critical examination of the represented reality in the novel. The result is a productive and dialectic literary dialogue, in which the topics of narration are a starting point to an aesthetic judgment that also requires the ability to empathize with the characters and situations, so that learners ultimately improve their discursive skills.

Influenze digitali sull’albo illustrato: metamorfosi artistiche e sfide di “iper-lettura”
Authors: Carioli Stefania
Published: January 2023

The influence of electronic and digital codes on children's literature represents one of the most interesting aspects of the artistic and literary productions of the last decades. Signs of the profound and irrevocable change that has taken place in children’s literature and in the ecosystem to be read of the electronic age are particular picturebooks, which reflect how even the printed book has drawn from the multilinear structures of the digital and from the expressive codes of the screens. In the context of this cultural mutation, the present contribution explores two illustrated books representative of the media technology mutation and integration, which, on the one hand, maintain the stability of reading on a traditional printed book, on the other, they contain the challenges of a "hyper-reading" experience.
Judges’ Freedom of Expression and the Reasonable Observer Test in International Soft Law: Relevant Documents, the Operationalization of the Test and the Scale of Expectations Placed on It
Authors: Wojtanowski Mateusz
Published: January 2023

The paper aims to discuss the reasonable observer test as a tool for assessing judges’ expression. The argument begins by analyzing the relevant provisions of international soft law, as inscribed in the instruments developed and adopted by the CoE and the UN. Subsequently, an operationalization of the test is proposed by identifying the factors to be taken into account in the application of the test. In the following step, the expectations placed on the reasonable observer test are addressed, whereby the juriscentric (“strong”) and post-analytical (“weak”) positions are outlined. The former relies on Artur Kozak’s law-philosophical conception, and the latter is underpinned by the topography of juristic power developed by Paweł Jabłoński and Przemysław Kaczmarek. The paper makes the case for the post-analytical approach, which places rather modest expectations on the reasonable observer test and considers it instrumental in structuring the discussion, rather than yielding indisputably reliable conclusions.

Published: January 2023

The subject of the study is the essential aspects and signs of the relations of interested users that develop in the process of developing the policy of tax accounting of agro-industrial processing organizations to assess the possibilities of optimizing value added tax (VAT). The purpose of the study is the theoretical justification and methodological support of the accounting tax policy from the point of view of the optimization processes of taxation of the object of research - the added value of processing organizations. The solution of the following tasks contributes to the achievement of this goal: to reveal the essence and content of the varieties of value added; to describe the features of VAT tax accounting in processing organizations of the agro-industrial complex; to substantiate the directions for improving the accounting tax policy of the object of research; to develop optimization measures for the policy of tax accounting. The methodological basis of the research is the methods that reveal the logic of the presentation: ideological – dialectical, deductive, inductive; general scientific - systemic; private scientific – statistical, analysis, comparison. The scientific novelty of the research consists in the development of methodological provisions of a recommendatory nature aimed at developing the policy of tax accounting of the object of research. The following provisions have the status of scientific increment: 1) the concept of "accounting tax optimization" is clarified, which is considered in contrast to traditional approaches, based on the trinity of essential characteristics of optimization processes; 2) methodological tools for improving the accounting tax policy on VAT in processing organizations of the agro-industrial complex are proposed, which differ from existing techniques and methods by eliminating contradictions between the accounting tax policy adopted by the organization and the methods of conducting tax accounting based on the implementation of regulatory legal opportunities: 1 - the content of the register of tax accounting and distribution of input VAT between taxable and non-taxable results of processing production is justified; 2 - the list of provisions of the accounting tax policy on VAT is characterized. The application of these recommendations in the course of forming a policy of value-added tax accounting and its optimization in processing organizations of the agro-industrial complex will contribute to increasing the tax solvency of these business entities.
Microstructure building and thermal stability of cermet-based photothermal conversion coatings with layered structures

To enhance the thermal stability of cermet-based photothermal conversion coatings, the present paper proposes a novel strategy to replace the randomly distributed nanoparticles with layered structure. This kind of structure can not only suppress the agglomeration and rapid growth of nanoparticles, but also enhance the interaction between the absorber and sunlight. Thus, the thermal stability and selectivity can be simultaneously improved by this unique kind of structure. Then, a Cr/AlCrN/AlCrON/AlCrO multilayer cermet-based photothermal conversion coating is designed and fabricated by multi-arc ion plating. The microstructure, optical properties and thermal stability of the multilayer coating are studied in detail. The optical properties tests show that the absorptance and emittance of the as-deposited coating achieve 0.903 and 0.183, respectively. More importantly, after being annealed at 500 ℃ in air for 1000 h, the absorptance reaches 0.913 and the emittance arrives at 0.199, implying the enhanced selectivity and thermal stability, which are ascribed to the formation of nanolaminates, in which a series of alternating sublayers is observed in the AlCrON absorber. The nanolaminate is a two-phase composite structure composed of layered AlN and Cr2N nanoparticles distributed in amorphous dielectric matrix. According to the finite difference time domain (FDTD) simulations, this unique kind of microstructure can trap photons in the coating, which is beneficial to enhancing the interaction intensity and time between the sunlight and absorbing sublayer, and thus improving the absorption of sunlight. In addition, the reduction of particle spacing during annealing will lead to the red shift of extinction spectrum, which will better match the solar radiation spectrum. At the same time, this kind of structure can avoid the agglomeration of nanoparticles, which can simultaneously tune the optical properties and thermal stability.
Testing the ion-current model for flagellar length sensing and IFT regulation
Authors: Ishikawa Hiroaki , Moore Jeremy , Diener Dennis R , Delling Markus , Marshall Wallace F
Published: January 2023

Eukaryotic cilia and flagella are microtubule-based organelles whose relatively simple shape makes them ideal for investigating the fundamental question of organelle size regulation. Most of the flagellar materials are transported from the cell body via an active transport process called intraflagellar transport (IFT). The rate of IFT entry into flagella, known as IFT injection, has been shown to negatively correlate with flagellar length. However, it remains unknown how the cell measures the length of its flagella and controls IFT injection. One of the most-discussed theoretical models for length sensing to control IFT is the ion-current model, which posits that there is a uniform distribution of Ca2+ channels along the flagellum and that the Ca2+ current from the flagellum into the cell body increases linearly with flagellar length. In this model, the cell uses the Ca2+ current to negatively regulate IFT injection. The recent discovery that IFT entry into flagella is regulated by the phosphorylation of kinesin through a calcium-dependent protein kinase has provided further impetus for the ion-current model. To test this model, we measured and manipulated the levels of Ca2+ inside of Chlamydomonas flagella and quantified IFT injection. Although the concentration of Ca2+ inside of flagella was weakly correlated with the length of flagella, we found that IFT injection was reduced in calcium-deficient flagella, rather than increased as the model predicted, and that variation in IFT injection was uncorrelated with the occurrence of flagellar Ca2+ spikes. Thus, Ca2+ does not appear to function as a negative regulator of IFT injection, hence it cannot form the basis of a stable length control system.
Taxonomic review of the genus Stenocaris Sars (Copepoda, Harpacticoida, Cylindropsyllidae), with (re)descriptions of two Stenocaris species from the Far East
Authors: Kim Jong Guk , Cho Kyuhee , Yoon Seong Myeong , Lee Jimin
Published: January 2023

The taxonomic concept of the genus Stenocaris Sars, 1909 is uncertain because none of the synapomorphies for the species of Stenocaris are defined. Detailed comparison of previous records of Stenocaris minor (T. Scott, 1892) from different localities reveals that this species represents a species complex composed of two species, S. minor s. str. and S. minor sensu Cottarelli & Venanzetti, 1989. Because the latter species has fundamental differences in the nature of the fifth leg in females and the sexual dimorphism of the second leg in males, we propose a new species for S. minor sensu Cottarelli & Venanzetti, 1989, S. figaroloensis sp. nov. We also suggest that S. minor sensu Apostolov, 1971, S. minor sensu Marinov, 1971, and S. minor sensu Apostolov & Marinov, 1988 from the Black Sea and S. minor sensu Wilson, 1932 from North America should be relegated to species inquirenda in the genus. Taxonomic review of the morphology of all Stenocaris species indicated that the generic concept must be restricted to accommodate S. minor s. str., S. gracilis Sars, 1909, S. intermedia Itô, 1972, S. figaroloensis sp. nov., and the South Korean new species, S. marcida sp. nov., based on the synapomorphic condition of the confluent fifth leg in males. As a result of our analysis, two Stenocaris species, S. baltica Arlt, 1983 and S. pygmaea Noodt, 1955, are transferred to the genus Vermicaris Kornev & Chertoprud, 2008 as V. baltica (Arlt, 1983) comb. nov. and V. pygmaea (Noodt, 1955) comb. nov. based on the synapomorphic characters of a reduced condition of the second and fifth legs. Additionally, S. arenicola Wilson, 1932 and S. kliei (Kunz, 1938) are allocated to a new genus, Huysicaris gen. nov., mainly characterized by obvious caudal rami with a recurved dorsal spinous process and convex inner margins, as H. arenicola (Wilson, 1932) comb. nov. and H. kliei (Kunz, 1938) comb. nov. A marine interstitial harpacticoid collected from the subtidal substrate off Dok-do Island in the East Sea of South Korea is proposed as S. marcida sp. nov. and the distribution of S. intermedia, originally known from its type locality in Japanese waters only, is extended to the East Sea of Korea and Russia. We provide their detailed descriptions and illustrations and discuss the morphological characters supporting their identities.
Chinese striped-neck turtles vocalize underwater and show differences in peak frequency among different age and sex groups
Authors: Zhou Lu , Lei Jinhong , Zhai Xiaofei , Shi Haitao , Wang Jichao
Published: January 2023

Background

Turtle vocalizations play an important role throughout their lives by expressing individual information (position, emotion, or physiological status), reflecting mating preferences, and synchronizing incubation. The Chinese striped-neck turtle (Mauremys sinensis) is one of the most widely distributed freshwater turtles in China, whose wild population is critically endangered. However, its vocalization has not been studied, which can be the basis for behavioral and ecological studies.

Methods

Five different sex–age groups of turtles were recorded underwater in a soundproof room. Cluster analysis and principal component analysis for classification of Chinese striped-neck turtle calls were unreasonable. The turtle calls were manually sought using visual and aural inspection of the recordings in Raven Pro 1.5 software and classified according to differences perceived through auditory inspection and the morphological characteristics of the spectrograms. The results of similarity analysis verified the reliability of manual classification. We compared the peak frequency of the calls among different age and sex groups.

Results

We identified tenM. sinensiscall types, displayed their spectra and waveforms, and described their auditory characteristics. Most calls produced by the turtles were low-frequency. Some high-frequency call types, that are common in other turtle species were also produced. Similar to other turtles, the Chinese striped-neck turtle generates harmonic vocalizations. Courtship behaviors were observed when one of the call types occurred in the mixed-sex group. Adult females produced more high-frequency call types, and subadult males had higher vocalizations than other groups. These results provide a basis for future research on the function of vocalizations, field monitoring, and conservation of this species.

The objective of the current systematic review was to evaluate the taxonomic composition and relative abundance of bacteria and archaea associated with the microbiologically influenced corrosion (MIC), and the prediction of their metabolic functions in different sample types from oil production and transport structures worldwide. To accomplish this goal, a total of 552 published studies on the diversity of microbial communities using 16S amplicon metagenomics in oil and gas industry facilities indexed in Scopus, Web of Science, PubMed and OnePetro databases were analyzed on 10th May 2021. The selection of articles was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Only studies that performed amplicon metagenomics to obtain the microbial composition of samples from oil fields were included. Studies that evaluated oil refineries, carried out amplicon metagenomics directly from cultures, and those that used DGGE analysis were removed. Data were thoroughly investigated using multivariate statistics by ordination analysis, bivariate statistics by correlation, and microorganisms’ shareability and uniqueness analysis. Additionally, the full deposited databases of 16S rDNA sequences were obtained to perform functional prediction. A total of 69 eligible articles was included for data analysis. The results showed that the sulfidogenic, methanogenic, acid-producing, and nitrate-reducing functional groups were the most expressive, all of which can be directly involved in MIC processes. There were significant positive correlations between microorganisms in the injection water (IW), produced water (PW), and solid deposits (SD) samples, and negative correlations in the PW and SD samples. Only the PW and SD samples displayed genera common to all petroliferous regions, Desulfotomaculum and Thermovirga (PW), and Marinobacter (SD). There was an inferred high microbial activity in the oil fields, with the highest abundances of (i) cofactor, (ii) carrier, and (iii) vitamin biosynthesis, associated with survival metabolism. Additionally, there was the presence of secondary metabolic pathways and defense mechanisms in extreme conditions. Competitive or inhibitory relationships and metabolic patterns were influenced by the physicochemical characteristics of the environments (mainly sulfate concentration) and by human interference (application of biocides and nutrients). Our worldwide baseline study of microbial communities associated with environments of the oil and gas industry will greatly facilitate the establishment of standardized approaches to control MIC.

Published: January 2023

Despite advancements in treatment, high‐grade serous ovarian cancer (HGSOC) is still characterized by poor patient outcomes. To understand the molecular heterogeneity of this disease, which underlies the challenge in selecting optimal treatments for HGSOC patients, we have integrated genomic, transcriptomic, and epigenetic information to identify seven new HGSOC subtypes using a multiscale clustering method. These subtypes not only have significantly distinct overall survival, but also exhibit unique patterns of gene expression, microRNA expression, DNA methylation, and copy number alterations. As determined by our analysis, patients with similar clinical outcomes have distinct profiles of activated or repressed cellular processes, including cell cycle, epithelial‐to‐mesenchymal transition, immune activation, interferon response, and cilium organization. Furthermore, we performed a multiscale gene co‐expression network analysis to identify subtype‐specific key regulators and predicted optimal targeted therapies based on subtype‐specific gene expression. In summary, this study provides new insights into the cellular heterogeneity of the HGSOC genomic, epigenetic, and transcriptomic landscapes and provides a basis for future studies into precision medicine for HGSOC patients.

Published: January 2023

Prostate‐specific membrane antigen (PSMA) is a cell surface protein highly expressed in nearly all prostate cancers, with restricted expression in some normal tissues. The differential expression of PSMA from tumor to non‐tumor tissue has resulted in the investigation of numerous targeting strategies for therapy of patients with metastatic prostate cancer. In March of 2022, the FDA granted approval for the use of lutetium‐177 PSMA‐617 (Lu‐177‐PSMA‐617) for patients with PSMA‐positive metastatic castration‐resistant prostate cancer (mCRPC) who have been treated with androgen receptor pathway inhibition and taxane‐based chemotherapy. Therefore, the use of Lu‐177‐PSMA‐617 is expected to increase and become more widespread. Herein, we describe logistical, technical, and radiation safety considerations for implementing a radiopharmaceutical therapy program, with particular focus on the development of operating procedures for therapeutic administrations. Major steps for a center in the U.S. to implement a new radiopharmaceutical therapy (RPT) program are listed below, and then demonstrated in greater detail via examples for Lu‐177‐PSMA‐617 therapy.

The biophysical microenvironment of cells dynamically evolves during embryonic development, leading to defined tissue specification. A versatile and highly adaptive magneto‐responsive hydrogel system composed of magnetic nanorods (MNRs) and a stress‐responsive polymeric matrix is developed to dynamically regulate the physical stem cell niche. The anisotropic magnetic/shape factor of nanorods is utilized to maximize the strains on the polymeric network, thus regulating the hydrogel modulus in a physiologically relevant range under a minimal magnitude of the applied magnetic fields below 4.5 mT. More significantly, the pre‐alignment of MNRs induces greater collective strains on the polymeric network, resulting in a superior stiffening range, over a 500% increase as compared to that with randomly oriented nanorods. The pre‐alignment of nanorods also enables a fast and reversible response under a magnetic field of the opposite polarity as well as spatially controlled heterogeneity of modulus within the hydrogel by applying anisotropic magnetic fields. The mechano‐modulative capability of this system is validated by a mechanotransduction model with human‐induced pluripotent stem cells where the locally controlled hydrogel modulus regulates the activation of mechano‐sensitive signaling mediators and subsequent stem cell differentiation. Therefore, this magneto‐responsive hydrogel system provides a platform to investigate various cellular behaviors under dynamic mechanical microenvironments.

Non‐contact human‐machine interaction is the future trend for wearable technologies. This demand is recently highlighted by the pandemic of coronavirus disease (COVID‐19). Herein, an anti‐fatigue and highly conductive hydrogel thermocell with photo‐thermal conversion ability for non‐contact self‐powering applications is designed. Double hydrogen‐bonding enhanced supramolecular hydrogel is obtained with N‐acryloyl glycinamide (NAGA) and diacrylate capped Pluronic F68 (F68‐DA) via one‐step photo‐initiated polymerization. The supramolecular hydrogel can accommodate saturated electrolytes to fulfill the triple function of ionic crosslinking, heat‐to‐electricity conversion, and light response of thermocell. Eminently, the thermocell stands out by virtue of its high seebeck coefficient (‐2.17 mV K−1) and extraordinary toughness (Fatigue threshold ≈ 3120 J m−2). The self‐powering ability under the control of light heating is explored, and a model of a non‐contact “light‐remoted” sensor with self‐powered and sensing integrated performance remote‐controlled by light is constructed. It is believed that this study will pave the way for the non‐contact energy supply of wearable devices.

Photoactivated Reversible Deactivation Radical Polymerization (RDRP) technologies have emerged very recently in the field of 3D printing systems especially at the macroscale in vat‐photopolymerization‐based processes such as digital light processing (DLP). Contrary to conventional free radical photopolymerization, photoRDRP in 3D printing leads to 3D objects with living character and thus confers them the unique ability to be post‐modified after fabrication. While 3D direct laser writing (3D DLW) by two photon polymerization has become a standard for fabrication of complex 3D micro‐objects, the use of RDRP and its associated benefits has so far been under‐investigated at that scale. Herein, a photoresist suitable for 3D DLW based on nitroxide mediated photopolymerization (NMP2) is developed. The photopolymerization efficiency for fabrication of micro‐structures and their subsequent post‐modification are investigated regarding the laser power and the wavelength of excitation. Moreover, highly tunable, precise, and successive surface patterning of 2D and 3D multi‐material microstructures are demonstrated thanks to the spatial and temporal control offered by the photo‐induced post‐modification. This work highlights new directions to be explored in order to accelerate the adoption of RDRP in 3D printing based on photopolymerization.

2D magnetic materials hold promise for quantum and spintronic applications. 2D antiferromagnetic materials are of particular interest due to their relative insensitivity to external magnetic fields and higher switching speeds compared to 2D ferromagnets. However, their lack of macroscopic magnetization impedes detection and control of antiferromagnetic order, thus motivating magneto‐electrical measurements for these purposes. Additionally, many 2D magnetic materials are ambient‐reactive and electrically insulating or highly resistive below their magnetic ordering temperatures, which imposes severe constraints on electronic device fabrication and characterization. Herein, these issues are overcome via a fabrication protocol that achieves electrically conductive devices from the ambient‐reactive 2D antiferromagnetic semiconductor NiI2. The resulting gate‐tunable transistors show band‐like electronic transport below the antiferromagnetic and multiferroic transition temperatures of NiI2, revealing a Hall mobility of 15 cm2 V−1 s−1 at 1.7 K. These devices also allow direct electrical probing of the thickness‐dependent multiferroic phase transition temperature of NiI2 from 59 K (bulk) to 28 K (monolayer).

Flexible biosensors exhibit great potential for the detection of various biomarkers with the ability to adapt to different surface textures. Here, a lab‐on‐a‐needle biosensing platform based on ultra‐flexible giant magnetoresistance (GMR) biosensors is developed. The fabricated flexible GMR sensors exhibit a MR ratio of 5.2% and a sensitivity of 0.13%/Oe in the linear region, which are comparable to their rigid counterparts. It is found that the magnetic properties of the flexible GMR sensors remain unchanged after 500 cycles of compressive and tensile stress, indicating strong robustness even when applied to a surface that is constantly in motion. The developed platform is then employed for the detection of different concentrations of canine osteosarcoma (OSCA‐8) cells with a limit of detection (LOD) of 200 cells in 20 µL sample (104 cells per mL), which demonstrate the ability to perform real‐time, sensitive, and quantitative cell detection.

Published: January 2023

Major depressive disorder (MDD) is associated with structural and functional brain abnormalities. MDD as well as brain anatomy and function are influenced by genetic factors, but the role of gene expression remains unclear. Here, this work investigates how cortical gene expression contributes to structural and functional brain abnormalities in MDD. This work compares the gray matter volume and resting‐state functional measures in a Chinese sample of 848 MDD patients and 749 healthy controls, and these case‐control differences are then associated with cortical variation of gene expression. While whole gene expression is positively associated with structural abnormalities, it is negatively associated with functional abnormalities. This work observes the relationships of expression levels with brain abnormalities for individual genes, and found that transcriptional correlates of brain structure and function show opposite relations with gene dysregulation in postmortem cortical tissue from MDD patients. This work further identifies genes that are positively or negatively related to structural abnormalities as well as functional abnormalities. The MDD‐related genes are enriched for brain tissue, cortical cells, and biological pathways. These findings suggest that distinct genetic mechanisms underlie structural and functional brain abnormalities in MDD, and highlight the importance of cortical gene expression for the development of cortical abnormalities.
