Published: January 2022

AbstractElectrospun poly(vinylidene fluoride) (PVDF)/sulfonated poly(1,4‐phenylene sulfide) (sPPS) blend nanofiber webs are prepared to investigate the changes in piezoelectric behavior of PVDF as a function of sPPS content using spectral and electrical measurements. Initial fourier transform infrared (FTIR) spectral analysis carried out using PVDF/sPPS as‐cast films provides useful information about the preferential formation of the β‐crystalline phase in PVDF. Even with the addition of 10 wt% of sPPS, β‐crystalline absorbance increases significantly in as‐cast PVDF film at the expense of a corresponding decrease in α‐crystalline absorbance. Cyclic–voltammetric analysis confirms the redox behavior of sPPS and its influence on improving the performance of PVDF/sPPS blend‐based piezoelectric sensor through hydrogen bonding and ion‐dipole interactions. The piezoelectric output signal recorded using PVDF/sPPS blend (95:5) nanofiber web shows ~4.4 times increase in output signal amplitude compared to that of neat PVDF based sensor, which is an evidence that the PVDF/sPPS nanofiber web material can be used as a commercially viable flexible pressure sensor.
Segmental and interfacial dynamics quantitatively determine ion transport in solid polymer composite electrolytes
Authors: Huang Yage , Mei Xintong , Guo Yunlong 
Published: January 2022

AbstractSolid polymer‐ceramic composite electrolytes (PCEs) have attracted vast attention for developing solid‐state batteries. However, slow ion transport at ambient temperature impedes unlocking their potential. Improving ionic conductivity of PCEs remains a major challenge, because ion transport mechanism in complicated composites is not currently available. This article, for the first time, demonstrates that segmental motion and interfacial polarization are directly coupled, both quantitatively determine ion transport in PCEs. Adding small‐molecule additives enhances ionic conductivity in PCEs, by increasing concentration of ions participating in transport and by equally accelerating segmental motion and interfacial dynamics. Accordingly, an ionic conductivity achieves 1.3 × 10−3 S/cm at 30°C, simultaneously with high mechanical strength and toughness (solid and flexible, shear modulus G' > 1 MPa). The results may shed a light for better analysis and improved design of solid composite electrolytes, toward meeting material demands for next‐generation electrochemical energy storage.
Re‐examining our roots: Queer history and anatomy
Authors: Smith Theodore C. 
Published: January 2022

AbstractSince its establishment as one of the major authorities on the human body, Anatomy has played a crucial role in social and political spheres. In this article, I review how the history of Anatomy has intersected with queer history and how the effects of these interactions have affected queer lives today. In these historical cases, I aim to demonstrate how Anatomy has affected the social organization of human culture and society and also how society has affected anatomical knowledge in return. As this reciprocal connection between Anatomy and societal organization is elucidated, I argue that anatomists, clinicians, and educators have an ethical duty to address the connections of this history, both in our research and our classrooms. This historical tour begins in the ancient world, which established a connection between sexuality and physiology and reproduction. This is followed by an exploration of the Renaissance and Enlightenment, which highlight the connections between anatomical knowledge, the law, and social organization. The progressive and modern eras are explored next via modern research into the anatomical and biological origins of same‐sex attraction and the use of modern technology in these investigations. Finally, the article ends with a call for reform along with suggestions for future steps.
Zinc oxide and gold textured Janus nanowire integration in an impedimetric sensor for leptospirosis DNA‐biomarker recognition

Published: January 2022

AbstractA “Janus particle” refers to the production of two materials in a single system and shows a difference in physical characteristics, and two surfaces participate in the formation with different chemistries. This research generated the Janus using a hybrid of zinc oxide (ZnO) and gold (Au) on the sensor surface toward making high‐performance DNA sensors. The Janus ZnO/Au‐textured film was synthesized via the one‐step sol–gel method, which involves a suitable ratio of a mixture of ZnO sol seed solution. The synthesized Janus ZnO/Au‐textured film undergoes a low‐temperature aqueous hydrothermal route to synthesize quasi‐one‐dimensional nanowires. The average grain size in the Janus ZnO/Au nanotextured wire was 41.60 nm. The fabricated nanotextured wire was further optimized by tuning the thickness and characterized by XRD and high‐resolution microscopy. Electrical characterization was conducted on the Janus ZnO/Au nanotextured wire coupled with an interdigitated electrode sensor to detect the specific leptospirosis DNA strand. The generated device is capable of detecting lower DNA concentration at 1 × 10–13 M with a sensitivity of 8.54 MΩ M–1 cm–2. The high performance is attained on linear concentrations of 10–6–10–13 M with the determination coefficient, “I = 135437.63C−3609.07” R2 = 0.9551. A potential strategy is proposed as a base for developing different high‐performance sensors.

Published: January 2022

AbstractFour novel coumarin fluorescence small‐molecules were successfully prepared and validated by proton nuclear magnetic resonance (1H‐NMR), carbon‐13 (13C)‐NMR, and mass spectrometry (MS). Their corresponding europium(III) complexes were synthesized and characterized. The ligand can emit green fluorescence in solutions, and the best concentration was 40 μmol/L. The emission peak of ligand has a red‐shift with the increase of concentration and solvent polarity. And the effect of various substituents in ligand was ordered using fluorescence intensity as standard: ‐NO2 > ‐Cl > ‐OCH3 > ‐OH. The order of fluorescence quantum yield is in line with the order of fluorescence intensity. The title europium complexes exhibit red fluorescence of europium ion (Eu3+) with good thermal stability. The effect of various substituents in ligand on the fluorescence intensity of title europium complexes was also consistent with the earlier results. This suggests that the prepared coumarins fluorescence small‐molecules and their corresponding europium complexes have potential application prospects in the field of optical materials.

Published: January 2022

AbstractIn vitro systems serve as compact and manipulate models to investigate interactions between different cell types. A homogeneous population of cells predictably and uniformly responds to external factors. In a heterogeneous cell population, the effect of external growth factors is perceived in the context of intercellular interactions. Indirect cell cocultivation allows one to observe the paracrine effects of cells and separately analyze cell populations. The article describes an application of custom‐made cell cocultivation systems based on protein membranes separated from the bottom of the vessel by the 3D printed holder or kept afloat by a magnetic field. Using the proposed cocultivation system, we analyzed the interaction of A549 cells and fibroblasts, in the presence and absence of growth factors. During cocultivation of cells, the expression of genes of the activation for epithelial and mesenchymal transitions decreases. The article proposes the application of a newly available system for the cocultivation of different cell types.
Case report: A novel application of the MicroVascular Plug (MVP) in treating distal coronary perforation
Authors: Low Randal J. B. , Khoo Deanna Z. L. , Ong Paul J. L. 
Published: January 2022

AbstractCoronary artery perforation during percutaneous coronary intervention (PCI) is a rare but severe complication which has been associated with a high rate of major adverse outcomes and is potentially fatal. We report a case of a 70‐year‐old male who presented with an anterior ST‐elevation myocardial infarction. Coronary angiogram revealed a proximal left anterior descending (LAD) artery occlusion. Successful PCI was performed with stenting of the LAD. However, subsequent attempts to retrieve a jailed diagonal branch inadvertently led to distal coronary perforation of the LAD. After failed attempts to tamponade the perforation with prolonged balloon inflation, this was successfully sealed with the MicroVascular Plug (Medtronic) system. To our knowledge, this is the first reported case of such an application in the coronary system. This may prove to be a viable alternative in closure of distal coronary perforations.

Published: January 2022

AbstractBackground and objectivesThis study aimed to tackle the research gaps regarding how different pulse types and extrusion conditions influenced starch digestibility and quality attributes of extruded dry pet foods. Flours of round pea, lentil, faba bean, wrinkled pea, and rice (control) were selected to extrude dry pet foods under “mild” (C1) and “extreme” (C2) conditions. Physicochemical properties, in vitro and in vivo starch digestibility of the resulting pet foods were characterized.FindingsUnder both conditions, wrinkled pea pet foods showed significantly lower damaged/gelatinized‐starch contents and less molecular breakdown than other samples. For all the formulations, the C2 condition gelatinized and degraded starch to greater extents than C1. Consistent with the structural and physicochemical properties of the extrudates, wrinkled pea pet foods exhibited notably lower digestibility in both in vitro and in vivo studies than other formulations.ConclusionsBoth pulse types and extrusion parameters effectively impacted the quality and starch digestibility of the extruded pet foods. Wrinkled pea flours showed high amylose contents and could be a promising ingredient for producing pet foods rich in resistant starch.Significance and noveltyThis study revealed the interrelationships among the structures, physicochemical properties, and starch digestibility of extruded pet foods formulated with normal and high‐amylose pulse flours.

Published: January 2022

AbstractUrinary bladder cancer is frequently multifocal and has a high incidence of recurrence. Although the prostatic urethra is a frequent site of tumor relapse in patients with non‐muscle‐invasive bladder cancer treated with TURBT, such tumors are often underdiagnosed. Here we present two cases having urethral recurrence after TURBT.

Study of the addition of a chemical mix additive and curing temperature on the setting time and mechanical properties of no‐cement castable
Authors: Cristante Ângelo 
Published: January 2022

AbstractTight installation schedules and economic pressures are potential drawbacks for castable installation and performance. Many factors influence the setting behavior and the properties of no‐cement castable refractories, including temperature and chemical composition. In this study, the setting behavior and the mechanical properties of a no‐cement castable were analyzed varying the amount of a chemical additive mix and curing temperature. The chemical additive mix concentration was varied from 0 wt% to 1 wt%. The curing temperature was varied from low (4°C/40°F) to high (40°C/104°F). The mechanical properties were characterized by cold crushing strength (CCS). A variance in the pH level drastically increased the setting time of the castable. Mechanical properties on green samples showed lower strength for castables with a higher concentration of the additive mix. This difference in performance is the result of the lower pH preventing the formation of a chain mechanism in the no‐cement castable bonded with colloidal silica.
High associative neuron numbers could drive cognitive performance in corvid species

Published: January 2022

AbstractCorvids possess cognitive skills, matching those of nonhuman primates. However, how these species with their small brains achieve such feats remains elusive. Recent studies suggest that cognitive capabilities could be based on the total numbers of telencephalic neurons. Here we extend this hypothesis further and posit that especially high neuron counts in associative pallial areas drive flexible, complex cognition. If true, avian species like corvids should specifically accumulate neurons in the avian associative areas meso‐ and nidopallium. To test the hypothesis, we analyzed the neuronal composition of telencephalic areas in corvids and noncorvids (chicken, pigeons, and ostriches—the species with the largest bird brain). The overall number of pallial neurons in corvids was much higher than in chicken and pigeons and comparable to those of ostriches. However, neuron numbers in the associative mesopallium and nidopallium were twice as high in corvids and, in correlation with these associative areas, the corvid subpallium also contained high neuron numbers. These findings support our hypothesis that large absolute numbers of associative pallial neurons contribute to cognitive flexibility and complexity and are key to explain why crows are smart. Since meso‐/nidopallial and subpallial areas scale jointly, it is conceivable that associative pallio‐striatal loops play a similar role in executive decision making as described in primates.
Appearance generation for colored spun yarn fabric based on conditional image‐to‐image translation
Authors: Zhang Ning , Xiang Jun , Wang Jingan , Pan Ruru , Gao Weidong 
Published: January 2022

AbstractThe repeated trial‐weaving and proofing process are traditionally conducted to exhibit the ever‐changing appearance of the colored spun yarn fabric knitted by different colored spun yarns. In this paper, a novel method of appearance generation for colored spun yarn fabric was proposed based on conditional image‐to‐image translation. The generated image is required to have the same color and the fabric style simultaneously as the color card and the assigned style. The common pix2pix model was modified by adding the category label to the image channel to involve the style constraint. To improve the generation performance, the U‐Net architecture was replaced by the residual block architecture. Four commonly used style fabrics and different color cards were adopted to build the image pairs for experiments. The visual inspection and category similarity were used as the evaluation metrics. Experimental results reveal that the proposed method can transfer different color cards to the designated style fabrics based on the constraints, being effective and superior for image generation of colored spun yarns. The proposed scheme can provide references for the designer by presenting the image perception, saving labor, and material resources in the proofing process.
Comprehensive phenotyping of human platelets by single‐cell cytometry
Authors: Spurgeon Benjamin E. J. , Frelinger Andrew L. 
Published: January 2022

AbstractPlatelets are small anucleate blood cells that contribute to hemostasis, immunity, and inflammation. Circulating platelets are heterogeneous in size, age, receptor expression, and reactivity. They inherit many features from megakaryocytes and are further modified on exposure to bioactive substances in the bloodstream. Among these substances, prothrombotic agonists, vasodilators, and bloodborne pathogens modulate platelet phenotypes via distinct signaling cascades. The ability of platelets to respond to (patho)physiologic signals is incompletely understood but likely depends on their repertoire of surface receptors, which may partition them into discrete subsets with specialized functions and divergent abilities. The single‐cell resolution of flow and mass cytometry is ideal for immunophenotyping and allows the identification of platelet subsets in remarkable detail. In this report, we describe the surface markers and gating strategies needed for the comprehensive characterization of platelets.
Sub‐micro scale cell segmentation using deep learning

Published: January 2022

AbstractAutomated cell segmentation is key for rapid and accurate investigation of cell responses. As instrumentation resolving power increases, clear delineation of newly revealed cellular features at the submicron through nanoscale becomes important. Reliance on the manual investigation of myriad small features retards investigation; however, use of deep learning methods has great potential to reveal cell features both at high accuracy and high speed, which may lead to new discoveries in the near term. In this study, semantic cell segmentation systems were investigated by implementing fully convolutional neural networks called U‐nets for the segmentation of astrocytes cultured on poly‐l‐lysine‐functionalized planar glass. The network hyperparameters were determined by changing the number of network layers, loss functions, and input image modalities. Atomic force microscopy (AFM) images were selected for investigation as these are inherently nanoscale and are also dimensional. AFM height, deflection, and friction images were used as inputs separately and together, and the segmentation performances were investigated on five‐fold cross‐validation data. Transfer learning methods, including VGG16, VGG19, and Xception, were used to improve cell segmentation performance. We find that AFM height images inherit more discriminative features than AFM deflection and AFM friction images for cell segmentation. When transfer‐learning methods are applied, statistically significant segmentation performance improvements are observed. Segmentation performance was compared to classical image processing algorithms and other algorithms in use by considering both AFM and electron microscopy segmentation. An accuracy of 0.9849, Matthews correlation coefficient of 0.9218, and Dice's similarity coefficient of 0.9306 were obtained on the AFM test images. Performance evaluations show that the proposed system can be successfully used for AFM cell segmentation with high precision.

Published: January 2022

AbstractThe ability to understand the way other people see the world differs from one's own viewpoint is referred to as ‘‘visual perspective‐taking’’ (VPT). Previous studies have demonstrated the behavioral performance in level 2 VPT (VPT2), the ability to understand that two different observers can have unique visual experiences of the same scene or object depending on the observers’ physical location, changes during childhood. However, the developmental aspects underlying the neural mechanisms of VPT2 remains unknown. We measured the hemodynamic responses to a VPT2 task using functional near‐infrared spectroscopy, with mental rotation (MR) as a control task in 7‐ to 11‐year‐old and 11‐ to 16‐year‐old groups. In the VPT2 task, participants were required to mentally compute the perspective of a toy on the turntable from that of a doll placed in a different location from the observer. For the MR task, participants reported their perspectives after the toy was rotated. We found significantly higher oxy‐hemoglobin changes during the VPT2 task than the MR task in the 7‐ to 11‐year‐old group but not in the 11‐ to 16‐year‐old group, in the right middle and superior temporal, angular gyrus and frontal regions. These findings highlight the important role of the right temporoparietal region in processing perspective, up to 11 years.
