AbstractBackgroundIn a single‐arm pilot study, we assessed the feasibility and usefulness of an innovative patient‐centered communication tool (UR‐GOAL tool) that addresses aging‐related vulnerabilities, patient values, and prognostic awareness for use in treatment decision making between older adults with newly diagnosed acute myeloid leukemia (AML), their caregivers, and oncologists.MethodsPrimary feasibility metric was retention rate; >50% was considered feasible. We collected recruitment rate, usefulness, and outcomes including AML knowledge (range 0–14) and perceived efficacy in communicating with oncologists (range 5–25). Due to the pilot nature and small sample size, hypothesis testing was performed at α = 0.10.ResultsWe included 15 patients (mean age 76 years, range 64–88), 12 caregivers, and 5 oncologists; enrollment and retention rates for patients were 84% and 73%, respectively. Patients agreed that the UR‐GOAL tool helped them understand their AML diagnosis and treatment options, communicate with their oncologist, and make more informed decisions. From baseline to post‐intervention, patients and caregivers scored numerically higher on AML knowledge (patients: +0.6, p = 0.22; caregivers: +1.1, p = 0.05) and perceived greater efficacy in communicating with their oncologists (patients: +1.5, p = 0.22; caregivers: +1.2, p = 0.06).ConclusionWe demonstrated that it is feasible to incorporate the UR‐GOAL tool into treatment decision making for older patients with AML, their caregivers, and oncologists.

Published: December 2022

AbstractSeven benzophenanthridine alkaloids (1–7) were obtained from the 75 % EtOH extract of Eomecon chionantha, and exhibited moderate biological activity against MCF‐7 cells. 8,12‐dimethoxysanguinarine (1, DSG) strongly decreased the cell viability of MCF‐7 cell lines with an IC50 value of 7.12 μΜ. Based on RNA‐sequencing measure and KEGG pathway enrichment analysis results, the significant differentially expressed genes (DEGs) were associated with Pathways in Cancer and PI3 K‐AKT signaling pathways in DSG treated group. The potential molecular regulatory mechanisms underlying the effect of DSG induces necroptosis in MCF‐7 cells via molecular docking, TEM analysis, and ROS measurement. Besides, DEGs of bone metastasis‐related genes such as PI3 K, IGF1R, Notch, and Wnt mRNA were significantly downregulated in the DSG‐treated group on MCF‐7 cells. DSG might be selected as a bone metastasis proteins inhibitor of IL‐1β, IL‐6, IκBα, IGF1R, Notch, NF‐κB, PTHrp, PI3 K, PKB/AKT, PTEN, TNF‐α, and Wnt via molecular docking. DSG suppressed bone metastasis by regulating the expression levels of IL‐1β, IL‐6, PTH, CROSS, TP1NP, and OSTEOC on MCF‐7 cells using ELISA measurement. Thus, our findings reveal that DSG could be a lead compound for suppressing tumor cells to bone metastasis in breast cancer cells.

AbstractThe exploration of economical and highly efficient electrocatalysts for hydrogen evolution reaction (HER) is paramount for the development of sustainable hydrogen economy. Herein, a novel three‐dimensional (3D) hierarchical microflower electrocatalyst comprised of N‐doped carbon‐armored Ni3P/Ni/VN heterogeneous nanoparticles (Ni3P/Ni/VN@NC) is developed by combining a hydrothermal method with in‐situ carbonization‐phosphating strategy. The unique robust hierarchical structure derived from 3D NiV layered double hydroxide (NiV‐LDH) skeleton as precursor provides multidimensional mass and charge transport channels as well as numerous active sites for HER, leading to the improved HER activity. More importantly, the possible electron transfer route of Ni3P→Ni→VN is demonstrated due to the charge pumping capability of VN during interfacial electron intercoupling among the tri‐component, which endows Ni3P/Ni/VN with the favorable absorption of hydrogen‐intermediates and thus upgraded HER kinetics over such heterostructure. The resulting Ni3P/Ni/VN@NC catalyst exhibits extremely low overpotentials of 81 mV and 134 mV to deliver a current density of 10 mA cm−2 without iR‐compensation in alkaline and acidic media, respectively, and maintains continuous operation for over 90 h. This work enlightens the rational design of hierarchical multi‐component heterostructured catalysts for efficient hydrogen production.

Published: December 2022

AbstractChemical structures possessing both 1,2,3‐triazole and bis(indolyl)methane fragments gained considerable interest in drug synthesis owing to their established biological efficacies. However, 1,2,3‐triazoles linked at the bridging position of bis(indolyl)methane is a logical and unexplored design approach. In this regard, nine new triazolyl‐bis(indolyl)methane conjugates under AuCl catalyzed ball‐milling conditions were accomplished. Comparative evaluation on absorptive and emissive properties of the synthesized dyads were also analyzed. To unravel the influence of different peripheral substituents on the electronic structure and π‐orbital properties, theoretical investigations were performed. Screening of molecules for free radical scavenging, anti‐inflammatory and antidiabetic showed comparable potency against reference drugs. In particular, compounds 7 h, 7 d and 7 a displayed good efficiency of α‐amylase inhibition. The DNA gyrase inhibitory potential of all compounds were assessed in silico which revealed high binding affinity (ΔG=−8.99 Kcal/mol) for 7 i followed by 7 h (ΔG=−7.80 Kcal/mol) with the targeted protein.

Published: December 2022

AbstractHere we report the encapsulation of an osteosarcoma stem cell (OSC) potent gallium(III)‐diflunisal complex 1 into polymeric nanoparticles, and its delivery into osteosarcoma cells. At the optimum feed (20 %, 1 NP20), nanoparticle encapsulation of 1 enhances potency towards bulk osteosarcoma cells and OSCs (cultured in monolayer and three‐dimensional systems). Strikingly, the nanoparticle formulation exhibits up to 5645‐fold greater potency towards OSCs than frontline anti‐osteosarcoma drugs, doxorubicin and cisplatin. The nanoparticle formulation evokes a similar mechanism of action as the payload, which bodes well for future translation. Specifically, the nanoparticle formulation induces nuclear DNA damage, cyclooxygenase‐2 downregulation, and caspase‐dependent apoptosis. To the best of our knowledge, this is the first study to demonstrate that polymeric nanoparticles can be used to effectively deliver an OSC‐active metal complex into osteosarcoma cells.
Crossover‐SGD: A gossip‐based communication in distributed deep learning for alleviating large mini‐batch problem and enhancing scalability

Published: December 2022

SummaryDistributed deep learning is an effective way to reduce the training time for large datasets as well as complex models. However, the limited scalability caused by network‐overheads makes it difficult to synchronize the parameters of all workers and gossip‐based methods that demonstrate stable scalability regardless of the number of workers have been proposed. However, to use gossip‐based methods in general cases, the validation accuracy for a large mini‐batch needs to be verified. For this, we first empirically study the characteristics of gossip methods in a large mini‐batch problem and observe that gossip methods preserve higher validation accuracy than AllReduce‐SGD (stochastic gradient descent) when the number of batch sizes is increased, and the number of workers is fixed. However, the delayed parameter propagation of the gossip‐based models decreases validation accuracy in large node scales. To cope with this problem, we propose Crossover‐SGD that alleviates the delay propagation of weight parameters via segment‐wise communication and random network topology with fair peer selection. We also adapt hierarchical communication to limit the number of workers in gossip‐based communication methods. To validate the effectiveness of our method, we conduct empirical experiments and observe that our Crossover‐SGD shows higher node scalability than stochastic gradient push.
Analysis of Thermal Characteristics of Batch Cooling Sonocrystallization: Effect on Crystal Attributes
Authors: Yadav Jyoti , Srivastava Abhishek , Patel Swati A. 
Published: December 2022

AbstractThe control of desired product quality attributes in the crystallization process is one of the major concerns of the pharmaceutical industries due to the established standard limits for active pharmaceutical ingredients in applications. The objective of the present work is to establish the fundamental understanding and methodology of the batch cooling sonocrystallization process to tune the crystal attributes over the range of operating parameters, i.e., ultrasound amplitude, duration of sonication, and cooling rate. For the constant cooling rate, the effect of three levels of ultrasound amplitude has been investigated over the range of durations of insonation. It is observed for a fixed cooling rate that the optimized set of ultrasound parameters shortens the induction time resulting in a finer range of particles increasing the surface area and narrowing the particle size distribution. The performance of the process in terms of thermal characteristics has been analyzed to delineate the effect of operating parameters to be employed as a function of the product characteristics. The simple expressions for temperature profiles during the process have been proposed as a function of saturation temperature to facilitate their applications in the optimization of the operating parameters for the desired product size and size range.
Unconformity generation and the shift from storm‐dominated to tide‐dominated processes in a Jurassic retroarc foreland basin: Insights from ichnology
Authors: Wroblewski Anton F.‐J. , Morris Emma A. 
Published: December 2022

AbstractAn enigmatic transition from the storm‐dominated, offshore to lower shoreface deposits of the Redwater Shale Member (Sundance Formation) to the overlying mixed tidal and aeolian Windy Hill Sandstone (Morrison Formation) in the Oxfordian of the North American Western Interior has long been a source of intrigue. Previously proposed drivers include the progradation of a large, tide‐dominated delta onto a storm‐dominated shelf, a complete reorganisation of the basin's hydrodynamics and climate, or the development of a regional unconformity (termed the J‐5). In south‐eastern Wyoming, the Redwater Shale is characterised as an offshore to distal shoreface deposit with glauconitic siltstones and sandstones punctuated by coquinoid and sandy tempestites and hosting a Cruziana Ichnofacies. The Windy Hill Sandstone, a time‐transgressive, sand‐rich, intertidal succession with classic Pteraichnus and stressed Skolithos Ichnofacies, sharply overlies the Redwater Shale and records an abrupt basinward shift in facies that accompanied at least tens of metres of sea‐level fall. New, detailed sedimentological, ichnological and architectural data collected across this transition in the study area provide fresh insights into the depositional history of these units and demonstrates the existence locally of a composite J‐5 unconformity. The unconformity developed as tectonically driven, prograding shoreline trajectories of the Redwater Shale gave way to degrading trajectories of the Windy Hill Sandstone, leading to a forced regression and formation of a regressive surface of marine erosion. The sharp juxtaposition of intertidal flat facies (Pteraichnus Ichnofacies) directly upon offshore to lower shoreface deposits (Cruziana Ichnofacies) is the key to recognising the unconformity and proves the value of the previously underutilised ichnological data.
Stereoselective Synthesis of 1,1’,2,2’‐Tetrasubstituted Ferrocenes by Double Lithiation of a 1,1’‐Disubstituted Ferrocenyl Pyrroloimidazolone

Published: December 2022

AbstractA 1,1’‐disubstituted ferrocenyl pyrroloimidazolone with syn stereochemistry undergoes double lithiation–electrophile quench in a one‐pot procedure to give C2‐symmetric 1,1’,2,2’‐tetrasubstituted products in >95 : 5 diastereomeric ratio (dr). These results represent an extension of double lithiation to access tetrasubstituted planar chiral ferrocenes for the first time to a nitrogen‐linked (pyrroloimidazolone) chiral directing group. The stereochemistry of the products was determined by X‐ray crystallography of distannane and dibromide adducts in combination with deuteration, elimination, and transmetalation experiments. Results support that products arise from selective deprotonation of the pro‐Sp position of each cyclopentadienyl (Cp) ring.
Deep learning models for analysis of non‐destructive evaluation data to evaluate reinforced concrete bridge decks: A survey
Authors: Lavadiya Dayakar Naik , Dorafshan Sattar 
Published: December 2022

AbstractApplication of deep learning (DL) for automatic condition assessment of bridge decks has been on the raise in the last few years. From the published literature, it is evident that lot of research efforts has been done in identifying the surface defects such as cracks, potholes, spalling and so forth using supervised learning methods such as deep learning. However, the health of a reinforced concrete bridge deck is jeopardized substantially due to presence of subsurface defects. Subsurface defects in bridge decks are genearlly detected using non‐destructive evaluation (NDE) methods. Interpertation of NDE data for autonomous deck evaluation requires development of DL models; however, The task of defect detection DL has not received the proper attention for subsurface defect detection in the past. The goal of this paper is to provide a review of existing DL models for analysis of NDE data of bridge decks. The authors reviewed prominent NDE techniques for subsurface defect detection of bridge decks and explored the various DL models proposed to identify these defects. First a brief overview of the working principle of NDE techniques and DL architectures is provided, and then the information about proposed DL models and their efficacy is highlighted. Based on the existing knowledge gaps, various challenges and future prospects associated with application of DL in bridge subsurface inspection are discussed.

AbstractApigenin (4′,5,7‐trihydroxyflavone) is a natural flavone reported to present anti‐diabetic and anti‐oxidative bioactivities. The effect of apigenin to mitigate endothelial dysfunction in diabetes remains to be investigated. In the present study, the vaso‐protective effect of apigenin as well as its underlying action mechanisms was investigated using in vitro‐ and in vivo‐based assays. Aortas were detached from C57BL/6J mice for ex vivo treatment, and primary rat aortic endothelial cells (RAECs) were cultured and further stimulated using high glucose (HG) with or without apigenin. In‐vivo diabetic model was established by feeding male C57BL/6J mice with a high‐fat diet (60% kcal% fat) for a total of 14 weeks, whereas the treatment group was orally administered apigenin (25 mg/kg/day) during the last 4 weeks. Exposure to HG (30 mM, 48 h) impaired acetylcholine‐induced endothelium‐dependent relaxation (EDR) in mouse aortas and induced oxidative stress with the downregulation of adenosine 5'‐monophosphate (AMP)‐activated protein kinase (AMPK)/phosphatidyl inositol 3‐kinase (PI3K)/protein kinase B (Akt)/endothelial nitric oxide synthase (eNOS) and nuclear factor erythroid 2‐related factor 2 (Nrf2)/heme oxygenase 1 (HO‐1) signaling pathways in aortas and RAECs. These impairments were reversed by apigenin treatments. However, the vaso‐protective effects of apigenin were abolished by Compound C (AMPK inhibitor) and wortmannin (PI3K inhibitor). Chronic oral administration with apigenin ameliorated EDR and reduced oxidative stress in the aortas of high‐fat diet (HFD)‐induced obese and diabetic mice. In conclusion, this study revealed that apigenin improved endothelial function and suppressed oxidative stress in the vasculature in diabetes through the activation of AMPK/PI3K/Akt/eNOS and Nrf2/HO‐1 pathways, suggesting its therapeutic potential as a natural dietary flavonoid against vascular diseases associated with diabetes.

Published: December 2022

AbstractThe pressure‐free two‐fluid model (PFTFM) is a recent reformulation of the one‐dimensional two‐fluid model (TFM) for stratified incompressible flow in ducts (including pipes and channels), in which the pressure is eliminated through intricate use of the volume constraint. The disadvantage of the PFTFM was that the volumetric flow rate had to be specified as an input, even though it is an unknown quantity in case of periodic boundary conditions. In this work, we derive an expression for the volumetric flow rate that is based on the demand for energy (and momentum) conservation. This leads to PFTFM solutions that match those of the TFM, justifying the validity and necessity of the derived choice of volumetric flow rate. Furthermore, we extend an energy‐conserving spatial discretization of the TFM, in the form of a finite volume scheme, to the PFTFM. We propose a discretization of the volumetric flow rate that yields discrete momentum and energy conservation. The discretization is extended with an energy‐conserving discretization of the source terms related to gravity acting in the streamwise direction. Our numerical experiments confirm that the discrete energy is conserved for different problem settings, including sloshing in an inclined closed tank, and a traveling wave in a periodic domain. The PFTFM solutions and the volumetric flow rates match the TFM solutions, with reduced computation time, and with exact momentum and energy conservation.

AbstractThe aquaponics production system integrates hydroponics and recirculatory aquaculture system for the simultaneous production of plants and fish. At a time, such as the postpandemic era, the aquaponics system represents an efficient green farming and eco‐friendly alternative to sustainable agricultural production. In this review, the history and development of the production systems were traced vis‐a‐vis its pros and cons. Although there has been much dispute about the origin of the system, the numerous records of developmental attempts in history have all led to the current complexity of the systems and their efficiency. Water conservation, improved performance, food security, less pollution, and low energy consumption are some of the advantages identified in the use of aquaponics systems for food production. Challenges to the domestication of the system, however, include moderately high start‐up capital, the need for stable electricity to operate the system, nutrient availability, as well as treatment of diseases in the system. Although the aquaponics production system could be a panacea for food security in Africa, modalities for the domestication of this technology are largely not in place, hence the need for some government interventions in this regard.

Published: December 2022

AbstractStimulated by a suggestion of the late Professor Jack D. Dunitz, that perdeuterated Janus face cycloalkanes may be more polar than their unlabelled forms, the deuterated isotopologue of all cis‐1,2,3,4,5,6‐hexafluorocyclohexane ([2H6]‐1a) and all cis‐1,2,3,4‐tetrafluorocyclopentane ([2H6]‐3a) were prepared. Computation at the B3LYP−D3 level indicated that [2H6]‐1a is not more polar than its protio form 1, however perdeuterated cyclopentane [2H6]‐3a may indeed be more polar than 3, although the magnitude is predicted to be small. None‐the‐less retention time analysis on a reverse phase GC/MS column of an add‐mix of 3 and [2H6]‐3a gave some indication that the per‐deuterated isotopologue 3a was detected marginally before the unlabelled compound consistent with increased polarity associated with perdeuteration.
