AbstractThe flow behaviour of 4‐(Dimethylsilyl) butyl ferrocene‐grafted HTPB‐based composite propellant (P01) and basic aluminized HTPB‐based propellant (P02) was investigated using shear rheometer. The experimental data were fitted to ‘power law’ for non‐Newtonian fluid flow, and the rheological parameters were expressed as consistency index (k) and pseudoplasticity index (n). For both the propellant compositions, a shear thinning nature (pseudoplasticity index; n < 1) has been observed. The study categorically showed that the incorporation of 4‐(Dimethylsilyl) butyl ferrocene‐grafted HTPB has resulted in increased consistency index (k) and yield stress as compared to HTPB based compositions. In addition, the time–temperature cure‐kinetics study suggested that the rate of curing reaction is higher with toluene diisocyanate as compared to isophorone diisocyanate and the Arrhenius activation energy (Ea) corroborated with the observed trend. Furthermore, the Haegen–Poisseuille equation modified for non‐Newtonian fluid flow has been employed to determine the theoretical casting rate for 4‐(Dimethylsilyl) butyl ferrocene‐grafted HTPB‐based composite propellant at different temperatures in a vacuum casting setup.

AbstractObjectivesTo investigate the predictive factors of delayed post‐percutaneous nephrolithotomy (PCNL) haemorrhage because of arteriovenous fistula (AVF) or pseudoaneurysm (PA) and compare the factors between AVF and PA.Patients and methodsThis is a case–control study with a case‐to‐control ratio of 1:3. Out of 5077 patients who underwent PCNL from April 2015 to April 2018 in three different teaching hospitals, 113 had post‐PCNL haemorrhages because of AVF and/or PA. Seventy‐two patients met the inclusion criteria and entered the study as cases, while 216 patients without any postoperative complications were selected as controls.ResultsOf all 72 studied patients with complications after PCNL, 35 (48.6%) had AVF, and the rest had PA. The regression model revealed that a history of diabetes (odds ratio [OR]: 2.799, 95% confidence interval [CI]: 1.392–5.630, p‐value = 0.004) and renal anomalies (OR: 2.929, 95% CI: 1.108–7.744, p‐value = 0.03) were associated with developing delayed post‐PCNL haemorrhage. However, no differences were seen between AVF and PA regarding selected variables (p‐value > 0.05).ConclusionHistory of diabetes and renal anomalies were predictive factors for delayed post‐PCNL haemorrhage, but no predictive factors were found to differentiate PA and AVF from one another.

AbstractAimWomen undergo behavioral changes during the menstrual cycle. This study aimed to investigate the effect of estradiol (Es) on stress and effect of stress on spatial working memory (WM) and also to investigate electroencephalogram (EEG) signal's dynamics in the early and late follicular (EF and LF) and luteal (LU) phases of unmarried girls’ menstrual cycle.MethodsStress was induced by presentation of a short (3 min) movie clip. Simultaneous with a memory test and stress induction, EEG, serum Es levels, and galvanic skin response (GSR) were assessed.ResultsSerum Es concentrations were decreased in LF, LU, and EF phases. The mean GSR score decreased after stress induction in all three phases, but it increased in the LF and LU phases versus the EF phase. Spatial WM diminished after stress induction in all three phases, but it increased in the LF phase versus the two phases before and after stress induction. Average power spectrum density in all frequency bands increased after stress induction in the frontal and prefrontal channels in the spatial WM test.ConclusionThe results showed that stress led to spatial WM dysfunction; however, Es improved spatial WM performance in the LF phase versus the other two phases.

AbstractThis study investigated the effect of the prone trunk extension test (PTE) on lumbar and lower limb muscle stiffness to explore the optimal angle for lumbar muscle training, understand the peripheral muscle force transmission effect, and determine the modulation strategy and interaction mode of different muscles during PTE. Twenty healthy young females were recruited for this study, and the stiffness of the erector spinae (ES), semitendinosus (ST), biceps femoris (BF), medial head of the gastrocnemius (MG), and lateral head of the gastrocnemius (LG) was measured by MyotonPRO under four angular PTE conditions (0° horizontal position, 10°, 20°, and 30°). With the increasing angle, the stiffness of ES decreased gradually, while ST and BF increased first and then decreased. The stiffness of MG and LG increased first, then decreased, then increased. There was a moderate to strong negative correlation between ES stiffness variation and ST (r = −0.819 to −0.728, p < 0.001), BF (r = −0.620 to −0.527, p < 0.05), MG (r = −788 to −0.611, p < 0.01), and LG (r = −0.616 to −0.450, p < 0.05). Horizontal PTE maximizes the activation of ES. There is a tension transfer between the ES, hamstrings, and gastrocnemius, mainly between the ES, ST, and LG. The study provides data to explore the effect of peripheral muscle force transmission and the modulation strategies of different muscles during trunk extension.

AbstractDuloxetine, a selective reuptake inhibitor for serotonin and norepinephrine, is a medication widely used for major depression. Currently, duloxetine is also recommended for pain related to chemotherapy‐induced peripheral neuropathy or cancer. Previously, we showed that transforming growth factor‐α (TGF‐α) induces the migration of human hepatocellular carcinoma (HCC)‐derived HuH7 cells through the activation of c‐Jun N‐terminal kinase (JNK), p38 mitogen‐activated protein kinase (MAPK) and AKT. In the present study, we investigate whether duloxetine affects cell migration and its mechanism. Duloxetine significantly enhanced the TGF‐α‐induced migration of HuH7 cells. Fluvoxamine and sertraline, specific inhibitors of serotonin reuptake, also upregulated the TGF‐α‐induced cell migration. On the contrary, reboxetine, a specific norepinephrine reuptake inhibitor, failed to affect cell migration. Duloxetine significantly amplified the TGF‐α‐stimulated phosphorylation of JNK, but not p38 MAPK and AKT. In addition, fluvoxamine and sertraline, but not reboxetine, enhanced the phosphorylation of JNK. SP600125, a JNK inhibitor, suppressed the enhancement by duloxetine, fluvoxamine, or sertraline of TGF‐α‐induced migration of HuH7 cells. Taken together, our results strongly suggest that duloxetine strengthens the TGF‐α‐induced activation of JNK via inhibition of serotonin reuptake in HCC cells, leading to the enhancement of cell migration.

AbstractThe reaction between diphosphorus derivatives [(ClImDipp)P2(Dipp)]OTf (1[OTf]) and [(ClImDipp)P2(Dipp)Cl] (1[Cl]) with the cyclotetraphosphido cobalt complex [K(18c‐6)][(PHDI)Co(η4‐cyclo‐P4)] (2) leads to the formation of complex [(PHDI)Co{η4‐cyclo‐P6(Dipp)(ClImDipp)}] (3), which features an unusual hexaphosphido ligand [ClImDipp=4,5‐dichloro‐1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐yl, Dipp=2,6‐diisopropylphenyl, 18c‐6=18‐crown‐6, PHDI=bis(2,6‐diisopropylphenyl)phenanthrene‐9,10‐diimine]. Complex 3 was obtained as a crystalline material with a moderate yield at low temperature. Upon exposure to ambient temperature, compound 3 slowly transforms into two other compounds, [K(18c‐6)][(PHDI)Co(η4‐P7Dipp)] (4) and [(PHDI)Co{cyclo‐P5(ClImDipp)}] (5). The novel complexes 3–5 were characterized using multinuclear NMR spectroscopy and single‐crystal X‐ray diffraction. To shed light on the formation of these compounds, a proposed mechanism based on 31P NMR monitoring studies is presented.

ZusammenfassungDie Neurotransmitter Dopamin und Serotonin spielen eine zentrale Rolle für das Glücksempfinden. Im Laufe der Menschheitsgeschichte gelang es immer wieder, neue chemische Stoffe des Glücks in immer höheren Konzentrationen und Mengen herzustellen. Alle sogenannten Glücksstoffe haben, vor allem bei langfristigem Einsatz Nachteile und bringen nur trügerisches Glück. Dabei fordern die akut giftigeren Stoffe keineswegs die meisten Opfer. Mit natürlichen Glückshormonen wird versucht, die künstlich zugesetzten Glücksdrogen und Genussmittel zu meiden oder den Konsum zu reduzieren und durch körpereigene Stoffe zu ersetzen.

AbstractBackgroundIn South Korea, the number of people with dementia is rising at a worrisome rate, and many of them also have acute myocardial infarction (AMI), a disease with a high mortality rate.HypothesisWe speculated that dementia and drug compliance have significant impact on the mortality of patients with AMI.MethodsThe study derived data from the National Health Insurance Service‐Senior for a retrospective cohort study. The total number of patients diagnosed with AMI for the first time between 2007 and 2013 was 16 835, among whom 2021 had dementia. Medication possession ratio (MPR) was used to assess medication adherence.ResultsAMI patients with dementia had unfavorable baseline characteristics; they had significantly higher risk of all‐cause mortality (hazard ratio [HR]: 2.49; 95% confidence interval [CI]: 2.34−2.66; p < .001) and lower MPR (aspirin: 21.9% vs. 42.8%; p < .001). AMI patients were stratified by presence of dementia and medication adherence, and the survival rate was the highest among those with no dementia and good adherence, followed by those with no dementia and poor adherence, those with dementia and good adherence, and those with dementia and poor adherence. The multivariable analysis revealed that dementia (HR: 1.64; 95% CI: 1.53−1.75; p < .001) and poor adherence to medication (HR: 1.60; 95% CI: 1.49−1.71; p < .001) had a significant association with all‐cause mortality in AMI patients.ConclusionsAMI patients with dementia have a higher mortality rate. Their prognosis is negatively affected by their poorer medication adherence than patients without dementia.
The emergence of the environmental color design praxis framework
Authors: McLellan Galyna , Franz Jill , Guaralda Mirko 
Published: July 2023

AbstractOver the last four decades, development in the environmental color design field challenged the prevailing designer's attitude towards selecting architectural and urban color palettes. Examining praxiological issues in environmental color design is necessary to reveal influential conditions that can facilitate or obstruct a shift in the design paradigm. This research article presents a qualitative study of environmental color design praxis (ECDP) in urban contexts. The study sought to understand how designers constructed their perspectives on contemporary ECDP, how these perspectives influenced their design approaches and the conditions under which designers can change their attitude and practices in environmental color design. The conceptual model of ECDP emerged from the grounded theory analysis of the interviews with Brisbane designers and the interpretation of relevant texts written by prominent designers and scholars. This article describes the core components of the ECDP model and provides interpretations of how educational, pragmatic and socio‐psychological factors influence dynamic changes in ECDP. The underlying research concludes that a holistic understanding of ECDP can inform the advanced and socially responsive environmental color design paradigm; the ECDP model provides a frame of reference for developing color design praxis theory.

AbstractThe interfacial electronic structure of perovskite layers and transport layers is critical for the performance and stability of perovskite solar cells (PSCs). The device performance of PSCs can generally be improved by adding a slight excess of lead iodide (PbI2) to the precursor solution. However, its underlying working mechanism is controversial. Here, we performed a comprehensive study of the electronic structures at the interface between CH3NH3PbI3 and C60 with and without the modification of PbI2 using in situ photoemission spectroscopy measurements. The correlation between the interfacial structures and the device performance was explored based on performance and stability tests. We found that there is an interfacial dipole reversal, and the downward band bending is larger at the CH3NH3PbI3/C60 interface with the modification of PbI2 as compared to that without PbI2. Therefore, PSCs with PbI2 modification exhibit faster charge carrier transport and slower carrier recombination. Nevertheless, the modification of PbI2 undermines the device stability due to aggravated iodide migration. Our findings provide a fundamental understanding of the CH3NH3PbI3/C60 interfacial structure from the perspective of the atomic layer and insight into the double‐edged sword effect of PbI2 as an additive.
T‐cell subsets in allergy and tolerance induction
Authors: Suhrkamp Ina , Scheffold Alexander , Heine Guido 
Published: July 2023

AbstractAntigen‐specific T lymphocytes are the central regulators of tolerance versus immune pathology against otherwise innocuous antigens and key targets of antigen‐specific immune therapy. Recent advances in the understanding of T cells in tolerance and allergy resulted from improved technologies to directly characterize allergen‐specific T cells by multiparameter flow cytometry or single‐cell sequencing. This unravelled phenotypically and functionally distinct populations, such as Type 2a T helper cells (Th2a), follicular Th cells (Tfh), regulatory T cells (Treg), Type 1 regulatory T cells (Tr1), and follicular T regulatory cells. Here we will discuss the role of the different Th‐cell subsets in the healthy state, during sensitization and development of allergy, and in tolerance induction by allergen immunotherapy (AIT). To date, the mechanisms of AIT as the only causal treatment of allergy are not completely understood. The analyses of allergen‐specific T cells directly ex vivo during AIT support the concept of specific‐Th2(a) cell deletion rather than an expansion of allergen‐specific Tr1 or Treg cells as underlying mechanism.

AbstractBackgroundWe analyzed the difference in treatment results according to safety margin range and studied the role of adjuvant therapy in patients with human papillomavirus‐positive (HPV+) oropharyngeal squamous cell carcinoma (OPSCC).Materials and methodsA total of 279 patients with HPV+ OPSCC were included in this study.ResultsSurgical margin and T classification were significant prognostic factors related to death. The difference in locoregional recurrence was analyzed by dividing the safety margin into groups of <1, 1–5, and >5 mm. There was no significant difference in local‐regional recurrence for T1–T2 lesions between the three groups. Adjuvant therapy can significantly reduce disease recurrence in HPV+ OPSCC patients with risk factors.ConclusionsIn T1–T2 lesions without other risk factors, even with a safety margin ≥1 mm, adjuvant therapy can potentially be omitted. Adjuvant therapy can significantly reduce disease recurrence in HPV+ OPSCC patients with risk factors.

AbstractThere is limited evidence about how physical activity (PA) programs should be provided for older Aboriginal and Torres Strait Islander peoples. Recently two groups of Aboriginal Elders on Noongar Boodja (Country) in Western Australia participated in the Ironbark PA program.Issue AddressedThe objective of this study was to explore the views of key stakeholders about the barriers and enablers to delivering a successful PA program and provide feedback for future program delivery.MethodsThe research took a ‘Nih (listening), Waangkiny (learning), Kaadatjiny (knowing)’ approach. The lead researcher, a Noongar Wadjuk woman, conducted semi‐structured interviews (n = 17) with key stakeholders: Aboriginal and non‐Aboriginal workers who assisted to deliver the program, and family and local members of the communities. Data were also collected through weekly program notes and researcher diary entries. Data were analysed thematically.ResultsThe overarching theme highlighted that stakeholders felt a sense of building a PA program that was culturally appropriate. They reflected that the program attracted older Aboriginal people because it was designed to make them feel welcomed with a sense of belonging. Five major themes were identified: Relationships, Belonging, Program structure, Benefits of the program and Future planning. Positive changes observed in Elders' health and well‐being were a source of inspiration for team workers.ConclusionsKey enablers to delivering a PA program for older Aboriginal people are building a culturally strong program that creates a sense of belonging for the participants.So What?Practitioners who are planning PA programs for older Aboriginal people should prioritise the development of cultural safety and security.

AbstractAmidst increased climatic disasters, persisting social evils, and governance concerns, sustainable finance and its new and innovative financial instruments have gained prominence across stakeholders globally. Green, social sustainability, sustainability‐linked, and transition (collectively GSS+) debt have a market worth USD 3.9 trillion since 2007 (Climate Bonds Initiative, 2018). We provide a comprehensive review of the evolution and future research directions of the sustainable finance research field by analysing overall publication trends, subject categories, co‐authorship networks, keywords, countries and institutions, journal co‐citation, and cluster analysis. Findings include the emergent need for greater collaboration among authors globally. Future research directions include research questions for themes such as carbon emission trading, financial inclusion, reporting of proceeds related to sustainable finance to prevent greenwashing, the impact of climate change and climate finance on sustainable finance, mobilisation of sustainable finance through green bonds, and technological interactions between sustainable finance and blockchain and artificial intelligence. The study also provides implications for the stakeholders.
Reimagining the English Language Arts canon: A case for inclusive and empowering instruction
Authors: Hunt Tracy E. 
Published: July 2023

AbstractThis paper explores the possible negative implications of teacher selected whole‐class reads rooted within the traditional canon of English Language Arts instruction and possible solutions for re‐engaging the disengaged adolescent reader through choice reading and the implementation of more culturally relevant texts. Historically, English Language Arts educators assign required readings to the entire class without taking into account the lens through which students view the texts. This paper identifies how texts deemed historically valuable and enabling by the educator can actually be disabling and disengaging to the learner. Additionally, this paper offers insights regarding the positive shifts that can stem from reimagining the traditional canon utilizing a whole‐class read scenario into a more democratic and culturally responsive English Language Arts canon. Assigned whole‐class reads are defined as selections of text chosen by the teacher with the understanding that every student is required to engage in the text. These are not chosen by students and they are not part of independent reading. The goal of this paper is to first, inform educators concerning the disabling effects of choosing whole‐class texts inside the traditional canon without viewing the texts through the varied interests, abilities, socio‐economic backgrounds, integration of students' cultural knowledge and experiences, and maturity levels of the students served. Furthermore, this paper will provide a basis for increasing educator knowledge regarding the traditional canon, disabling and enabling texts, and culturally responsive ELA practices along with particular scaffolds in hopes of re‐engaging the disengaged adolescent reader.

Published: July 2023

AbstractEGFL7 is a proangiogenic factor. It has been widely described with having a vital role in tubulogenesis and regulation of angiogenesis, mainly during embryogenesis and organogenesis. It has been mainly associated with NOTCH pathway, but there are reports showing association with MAPK and integrin pathways. Given its association with angiogenesis and these other pathways, there are several studies associating EGFL7 with carcinogenesis. In fact, most of the studies have pointed to EGFL7 as an oncogene, and some of them suggest EGFL7 expression as a possible biomarker of prognosis or use for a patient's follow‐up. Here, we review the molecular pathways which EGFL7 is associated and highlight several studies describing the role of EGFL7 in tumorigenesis, separated by tumor type. Besides its role on angiogenesis, EGFL7 may act in other pathways as oncogene, which makes it a possible biomarker and a candidate to targeted therapy.
