Authors: Hojker Marta , Vaishnav Jahnavi , Staparski Dobravec Saša 
Published: July 2023

Background: The incidence of back pain in childhood is rising and significantly impacts its incidence in adulthood. Important risk factors include poor posture, which is common due to a largely sedentary lifestyle. Our study aimed to determine the effect of a primary prevention programme on posture and pain incidence in primary school children.
Methods: The research was conducted in eight 4th grades of four primary schools. Half of the grades were part of the posture hygiene programme throughout the school year, while the other half served as a control group. Before and after the programme, pupils were measured, their posture assessed, and a survey about back pain was conducted.
Results: 179 pupils were included in the study. A history of back pain was found in 36.5% of the children, and only 9% had ideal posture. The implementation of the programme resulted in a 20% absolute reduction in the risk of pain and a 52% reduction in those who reported pain before the programme. At the end of the study, there was a statistically significant difference (p<0.001) between the two groups in all the measured parameters, except in the cranioclavicular angle.
Conclusion: The study showed marked improvement in posture and reduced back pain in the students who were included in the programme. A preventive programme to improve postural hygiene could contribute significantly to addressing the problem among young people, thus reducing the incidence of back pain in the adult population.

Published: July 2023

Izhodišča: Čeprav so srčne kateterizacije v primerjavi s kardiokirurškimi posegi manj invazivne, imajo manj zapletov, bolniki pa po njih hitreje okrevajo, te niso brez zapletov. Z raziskavo smo želeli ugotoviti značilnosti populacije, najpogostejše patologije, vrste kateterizacij, zaplete pri kateterizacijah v našem centru ter opredeliti morebitne dejavnike tveganja.
Metode: Zbrali smo podatke o vseh pediatričnih srčnih kateterizacijah, opravljenih med junijem 2018 in avgustom 2021. Opredelili smo jih glede na vrsto kateterizacije (diagnostične in terapevtske), težo, starost, spol bolnikov in kompleksnost patologije. Zaplete smo ločili na lažje in težje ter z uporabo Pearsonovega testa hi-kvadrat in testa Mann-Whitney U ugotavljali njihovo povezanost s morebitnimi dejavniki tveganja.
Rezultati: V tem obdobju je bilo opravljenih 191 srčnih kateterizacij (54 diagnostičnih in 137 terapevtskih) pri 175 otrocih, od tega pri 95 dečkih in 80 deklicah. Otroci so bili stari od nekaj ur do 18 let, tehtali so od 2,6 kg do 85,5 kg. Zabeležili smo 9 zapletov, od tega 5 težjih in 4 lažje. Z našo raziskavo nismo dokazali statistično pomembne povezave med dejavniki tveganja (telesna teža, spol, vrsta kateterizacije, starost, kompleksnost patologije) in pojavom zapletov.
Zaključek: Največ kateterizacij je bilo opravljenih pri otrocih, starih med 1 letom in 10 let in tistih, ki so tehtali med 10 in 40 kg. Nekoliko več kateterizacij je bilo opravljenih pri dečkih. Najpogostejše so bile terapevtske kateterizacije. Pojavnost zapletov v našem centru je primerljiva z drugimi centri. Telesna teža, spol, starost otroka, vrsta kateterizacije in kompleksnost patologije v našem centru niso bili statistično značilno povezani s pojavom zapletov ob katerizaciji.

Aims: The present research was done to evaluate the antioxidant activity of aqueous extract of Withania somnifera (Ashwagandha) in equine. Herbal antioxidants have gained popularity due to their potency and safety, and oxidative stress is a condition that is more prevalent in horses performing physical activities.
Methods: Twenty clinically healthy horses were selected and equally divided into treatment and control group consisting of 10 animals in each. An aqueous extract was prepared from dried root powder of Withania somnifera (Ashwagandha) and was continuously administered orally for 15 days to treatment group animals @ 100 mg/kg body weight. Blood samples were collected on 0 th, 8th, and 16th day from both the treatment and control group. The plasma was used for the determination of enzymatic oxidants (Catalase (CAT) and superoxide dismutase (SOD) and non-enzymatic antioxidants (reduced glutathione (GSH) and Vitamin C).
Results: A non-significant increase in the values of Catalase, Superoxide Dismutase (SOD), Reduced Glutathione (GSH), and Vitamin C were observed after administration of aqueous extract of Withania somnifera.
Conclusion: Administration of aqueous extract of Withania somnifera not significantly modulated the activity of enzymatic and non-enzymatic antioxidants.

AbstractObjectivesTo explore filtered diffusion‐weighted imaging (fDWI), in comparison with conventional magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI), as a predictor for long‐term locomotor and urodynamic (UD) outcomes in Yucatan minipig model of spinal cord injury (SCI). Additionally, electrical conductivity of neural tissue using D‐waves above and below the injury was measured to assess correlations between fDWI and D‐waves data.MethodsEleven minipigs with contusion SCI at T8‐T10 level underwent MRI at 3T 4 h. post‐SCI. Parameters extracted from region of interest analysis included Daxial from fDWI at injury site, fractional anisotropy and radial diffusivity from DTI above the injury site along with measures of edema length and cord width at injury site from T2‐weighted images. Locomotor recovery was assessed pre‐ and weekly post‐SCI through porcine thoracic injury behavior scale (PTIBS) and UD were performed pre‐ and at 12 weeks of SCI. D‐waves latency and amplitude differences were recorded before and immediately after SCI.ResultsTwo groups of pigs were found based on the PTIBS at week 12 (p < 0.0001) post‐SCI and were labeled “poor” and “good” recovery. D‐waves amplitude decreased below injury and increased above injury. UD outcomes pre/post SCI changed significantly. Conventional MRI metrics from T2‐weighted images were significantly correlated with diffusion MRI metrics. Daxial at injury epicenter was diminished by over 50% shortly after SCI, and it differentiated between good and poor locomotor recovery and UD outcomes.InterpretationSimilar to small animal studies, fDWI from acute imaging after SCI is a promising predictor for functional outcomes in large animals.

AbstractWith the emerging problem of antimicrobial resistance, the world is facing a slow but dangerous pandemic. While the discovery of novel antibiotics is reaching a nearly exhaustive end, new concepts for anti‐infective drugs are emerging. So‐called pathoblockers aim to de‐weaponize bacteria rather than just killing them. As the target of these molecules is typically located intracellularly, however, hitherto almost unnoticed biological barriers are emerging such as the biofilm matrix, the bacterial cell envelope, efflux pumps, and eventual bacterial metabolism. This leads to a new paradigm that is to maximize bacterial bioavailability. To overcome the bacterial barriers, especially when further optimization of the active molecules is not possible, functional materials are needed to engineer innovative delivery systems. Those may not only enable novel anti‐infective molecules to reach their targets, but will also improve the bacterial bioavailability of existing anti‐infectives. Additionally, there is a need for better infection models that allow studying drug effects on both the bacteria and the host in a relevant manner as needed for rational anti‐infective drug development.

AbstractThe efficiency of organic solar cells (OSCs) is primarily limited by their significant nonradiative energy loss and unfavorable active layer morphology. Achieving high‐efficiency OSCs by suppressing nonradiative energy loss and tuning the active layer morphology remains a challenging task. In this study, an acceptor named CH‐ThCl is designed, featuring an extended conjugation central core, dichlorodithienoquinoxaline. The incorporation of chlorine‐substituted extended conjugation in the central core enhances the acceptor's rigidity and promotes J‐aggregation, leading to improved molecular luminescent efficiency and a reduction in nonradiative energy loss. A binary device based on PM6: CH‐ThCl demonstrates a power conversion efficiency (PCE) of 18.16% and exhibits a high open‐circuit voltage (Voc) of 0.934 V, attributed to the remarkably low nonradiative energy loss of 0.21 eV. Furthermore, a ternary device is fabricated by incorporating CH‐6F as the third component, resulting in a significantly enhanced PCE of 18.80%. The ternary device exhibits improvements in short‐circuit current (Jsc) and fill factor (FF) while maintaining the Voc, primarily due to the optimized active layer morphology. These results highlight the effectiveness of combining the reduction of nonradiative energy loss and precise tuning of the active layer morphology as a viable strategy for achieving high‐efficiency OSCs.

AbstractThe fiber structures of tumor microenvironment (TME) are well‐known in regulating tumor cell behaviors, and the plastic remolding of TME has recently been suggested to enhance tumor metastasis as well. However, the interrelationship between the fiber microarchitecture and matrix plasticity is inextricable by existing in vitro models. The individual roles of fiber microarchitecture and matrix plasticity in tuning tumor cell behaviors remain elusive. This study develops an interpenetrating collagen–alginate hydrogel platform with independently tunable matrix plasticity and fiber microarchitecture through an interpenetrating strategy of alginate networks and collagen I networks. With this hydrogel platform, it is demonstrated that tumor cells in high plasticity hydrogels are more extensive and aggressive than in low plasticity hydrogels and fiber structures only have influence in high plasticity hydrogels. The study further elucidates the underlying mechanisms through analyzing the distribution of forces within the matrix and tracking the focal adhesions (FAs) and finds that highly plastic hydrogels can activate the FAs formation, whereas the maturation and stability of FAs are dominated by fiber dispersion. This study not only establishes new ideas on how cells interact with TME cues but also would help to further finely tailor engineered hydrogel platforms for studying tumor behaviors in vitro.
Liquid Crystals Doped with Chiral Fluorescent Polymer: Multi‐Color Circularly Polarized Fluorescence and Room‐Temperature Phosphorescence with High Dissymmetry Factor and Anti‐Counterfeiting Application
Authors: Wang Xujie , Zhao Biao , Deng Jianping 
Published: July 2023

AbstractChiral nematic liquid crystals (N*‐LCs) can tremendously amplify circularly polarized luminescence (CPL) signals. Doped emissive N*‐LCs have been substantially explored. However, their CPL performances still need to be improved, mainly due to the unsatisfying helical twisting power (HTP) of commonly used chiral fluorescent dopants. Chiral fluorescent helical polymers (CFHPs) have outstanding optical activity and CPL performance. The present contribution reports the first success in constructing emissive N*‐LCs by doping CFHP into nematic liquid crystals (5CB, N‐LCs). The helical assembly structures of N*‐LCs effectively amplify the CPL signals of the CFHP. Owing to the high HTP of CFHP, the selective reflection band of N*‐LC can be adjusted to fully cover its emission band. A nearly pure CPL with a dissymmetry factor (glum) up to −1.87 is realized at 9 wt% doping concentration. Taking advantage of the selective reflection mechanism, multi‐color CPL‐active N*‐LCs with high glum are fabricated via further adding achiral fluorophores. Also noticeably, circularly polarized room‐temperature phosphorescence with glum up to −1.57 is achieved. Anti‐counterfeiting application is demonstrated by exploiting multi‐mode optical characteristics of the created N*‐LCs. The established strategy for constructing emissive N*‐LCs provides a platform for future exploring of CPL‐active N*‐LCs.

Published: July 2023

AbstractExtensive study on 2D van der Waals (vdW) heterojunctions has primarily focused on PN diodes for fast‐switching photodetection, while achieving the same from 2D channel phototransistors is rare despite their other advantages. Here, a high‐speed phototransistor featuring a type III junction between p‐MoTe2 channel and n‐SnS2 top layer is designed. The photodetecting device operates with a basis of negative photoresponse (NPR), which originates from the recombination of photoexcited electrons in n‐SnS2 and accumulated holes in the p‐MoTe2 channel. For the NPR to occur, high‐energy photons capable of exciting SnS2 (band gap ≈2.2 eV) are found to be effective because lower‐energy photons simply penetrate the SnS2 top layer only to excite MoTe2, leading to normal positive photoresponse (PPR) which is known to be slow due to the photogating effects. The NPR transistor showcases 0.5 ms fast photoresponses and a high responsivity over 5000 A W−1. More essentially, such carrier recombination mechanism is clarified with three experimental evidences. The phototransistor is finally modified with Au contact on n‐SnS2, to be a more practical device displaying voltage output. Three different photo‐logic states under blue, near infrared (NIR), and blue‐NIR mixed photons are demonstrated using the voltage signals.

Published: July 2023

AbstractFew‐walled carbon nanotube (FWCNT) is composed of a few coaxial shells of CNTs with different diameters. The shells in one tube can slide relatively to each other under external forces, potentially leading to regulated electrical properties, which are never explored due to experimental difficulties. In this work, the electromechanical response induced by inter‐shell sliding of individual CNTs is studied and revealed the linear electrical current variation for the first time. Based on centimeter‐long FWCNTs grown through chemical vapor deposition, controllable and reversible inter‐shell sliding is realized while simultaneously recording the electrical current. Reversible and linear current variation with inter‐shell sliding is observed, which is consistent with the proposed inter‐shell tunneling model. Further, a silk fibroin‐assisted transfer technique is developed for long CNTs and realized the fabrication of FWCNT‐based flexible devices. Tensile stress can be applied on the FWCNTs@silk film encapsulated in elastic silicone to induce inter‐shell sliding and thus controls electrical current, which is demonstrated to serve as a new human–machine interface with high reliability. Besides, it is foreseen that the electromechanical behaviors induced by inter‐layer sliding in 1D nanotubes may also be extended to 2D layered materials, shedding new light on the fabrication of novel electronics.

AbstractPurifications of biologics can be improved using 3D printed stationary phases with perfectly ordered morphology. However, limited spatial resolution and lack of porous materials have hindered application of additive manufacturing in bioprocessing. To bridge this gap, digital light processing and polymerization‐induced phase separation are combined to fabricate platform materials with bed morphology at the micrometer scale, and porous network in the nanometer scale. Four different porous inks are developed, 3D printed, and characterized in terms of their rheological behaviour, polymerization kinetics, and printing resolution. Rapid 3D printing (down to 1 h) is achieved at scale (up to 100 mL column) of porous supports (50% porosity) at high resolution (up to 50 µm for linear features and 200 µm for complex geometries). 3D‐printed gyroids are chemically functionalized with various ion exchange ligands. These are successfully challenged for i) the separation of model proteins in dynamic conditions and ii) protein capture from a clarified cell harvest, demonstrating dynamic binding capacities between 5 and 16 mg mL−1 and up to 86% purity in a single run. This work introduces a rapid and facile approach to 3D printing porous inks to fabricate perfectly ordered stationary phases for downstream processing.

Published: July 2023

AbstractIntegrated hierarchical microstructures composed of organic micro/nanocrystals with defined morphology have received great interest as candidates for advanced photonic circuits. Herein, the synthesis of highly ordered multilevel homogenous hyperbranched networks (HHNs) made of the individual organic compound 2, 3‐dicyanine naphthalene via a facile solution self‐assembly route is reported. The selective growth of branches on the sidewall of the backbone driven by the lattice match mechanism leads to the formation of higher‐level snowflake‐like configuration of the HHNs. These well‐organized HHNs perform excellent abilities of directional asymmetry photon transport and hierarchical polarization filtering. Combined with the doping strategy, the broad emission range of hyperbranched network heterostructures is expanded, and even the white light emission with Commission Internationale de L'Eclairage coordinates at (0.30, 0.33) is realized. This work provides deep insight into the rational creation of complex organic heterostructures for novel photoelectric devices with desired performances.
Atomic Spin Detection Method Based on Spin‐Selective Beam‐Splitting Metasurface

Published: July 2023

AbstractThe current polarization differential detection method used for atomic co‐magnetometers and other atomic sensors usually depends on the beam splitting plane at 45° from the incident light, so the beam splitter needs a certain thickness and a second optical path perpendicular to the original optical axis for detection, which restricts the integration degree of the beam splitter and photodetectors on the probe optical path. To address this issue, a new spin‐selective beam‐splitting metasurface‐based technique for atomic spin detection is proposed in this study, which utilizes a silicon nitride (SiN) metasurface for chiral beam‐splitting detection. The experimental results show that the 2.8 × 2.8 mm fabricated metasurface supports the beam splitting focusing of the left and right circular partial incident light with a distance up to 1.340 mm. It has a remarkable ability to detect optical rotation angles, achieving an angular measurement sensitivity of 3.0526 × 10−5 rad at 70 kHz. Compared with the traditional beam splitter, the probe's optical path volume can be reduced by at least 80%. This method can enhance the integration of atomic sensors and provide a novel approach for the development of atom sensors on chips.

Published: July 2023

AbstractChiral phosphoric acid (CPA) has been established as a cornerstone in chemical synthesis reactions for over five decades, owing to its distinctive molecular structure and remarkable catalytic effect. However, in recent years, a revolutionary approach to asymmetric synthesis has emerged, utilizing photocatalytic excitation of molecules to generate free radicals, effectively surpassing the limitations of classical organic synthesis methodologies.A prominent and significant area of research has been dedicated to the investigation of chiral phosphoric acid synergistic photocatalysis for enantioselective chemical synthesis. This unique catalytic system encompasses a bifunctional hydrogen‐bonding catalyst, enabling simultaneous interactions between radical intermediates and substrates. The review paper focuses on the application and progress of this catalytic system in asymmetric synthesis throughout the past decade.
