Authors: Li Jing , Ma Binyi , Liu Yanfei , Guo Honglei , Wu Qiannan , Li Mengwei 
Published: August 2023

This paper proposes a switchable terahertz (THz) metamaterial absorber based on vanadium dioxide (VO2), which can not only realize ultra-wideband (UWB) perfect absorption in the THz range, but also has the ability to adjust the absorption rate by regulating the conductivity of VO2. When VO2 conductivity is 2×105S/m, the designed UWB absorber can achieve over 90% absorption in the frequency range of 2.62–10 THz. Simultaneously, the peak absorption intensity of the absorber can also be regulated dynamically ranging from 100% to 0.8% when the conductivity of VO2 is adjusted to change from 2×105 to 20 S/m. Furthermore, the designed absorber has the advantages of polarization insensitivity and wide-angle absorption. For TE polarization with an incident angle of less than 40° and TM polarization with an incident angle of less than 60°, the absorption rate remains above 90%. The UWB absorber has the advantages of simple structure, wide tuning range, and good absorption performance, and it has potential applications in many fields such as THz filtering, invisibility, sensing, optoelectronic switches, and so on.

Published: August 2023

Background
Several studies indicate that the anterior visual pathway provides information about the dynamics of axonal degeneration in Multiple Sclerosis (MS). Current research in the field is focused on the quest for the most discriminative features among patients and controls and the development of machine learning models that yield computer-aided solutions widely usable in clinical practice. However, most studies are conducted with small samples and the models are used as black boxes. Clinicians should not trust machine learning decisions unless they come with comprehensive and easily understandable explanations.

Materials and methods
A total of 216 eyes from 111 healthy controls and 100 eyes from 59 patients with relapsing-remitting MS were enrolled. The feature set was obtained from the thickness of the ganglion cell layer (GCL) and the retinal nerve fiber layer (RNFL). Measurements were acquired by the novel Posterior Pole protocol from Spectralis Optical Coherence Tomography (OCT) device. We compared two black-box methods (gradient boosting and random forests) with a glass-box method (explainable boosting machine). Explainability was studied using SHAP for the black-box methods and the scores of the glass-box method.

Results
The best-performing models were obtained for the GCL layer. Explainability pointed out to the temporal location of the GCL layer that is usually broken or thinning in MS and the relationship between low thickness values and high probability of MS, which is coherent with clinical knowledge.

Conclusions
The insights on how to use explainability shown in this work represent a first important step toward a trustworthy computer-aided solution for the diagnosis of MS with OCT.

ObjectiveThis study aimed to evaluate whether exercise training could contribute to a better modulation of the neurohumoral mechanisms linked to the pathophysiology of arterial hypertension (AH) in postmenopausal hypertensive rats treated with hydrochlorothiazide (HCTZ).MethodsFemale spontaneously hypertensive rats (SHR) (150−200g, 90 days old) were distributed into 5 hypertensive groups (n = 7–8 rats/group): control (C), ovariectomized (O), ovariectomized treated with HCTZ (OH), ovariectomized submitted to exercise training (OT) and ovariectomized submitted to exercise training and treated with HCTZ (OTH). Ovarian hormone deprivation was performed through bilateral ovariectomy. HCTZ (30mg/kg/day) and concurrent exercise training (3d/wk) were conducted lasted 8 weeks. Arterial pressure (AP) was directly recorded. Cardiac effort was evaluated using the rate-pressure product (RPP = systolic AP x heart rate). Vasopressin V1 receptor antagonist, losartan and hexamethonium were sequentially injected to evaluate the vasopressor systems. Inflammation and oxidative stress were evaluated in cardiac tissue.ResultsIn addition to the reduction in AP, trained groups improved RPP, AP variability, bradycardic (OT: −1.3 ± 0.4 and OTH: −1.6 ± 0.3 vs. O: −0.6 ± 0.3 bpm/mmHg) and tachycardic responses of baroreflex sensitivity (OT: −2.4 ± 0.8 and OTH: −2.4 ± 0.8 vs. O: −1.3 ± 0.5 bpm/mmHg), NADPH oxidase and IL-10/TNF-α ratio. Hexamethonium injection revealed reduced sympathetic contribution on basal AP in OTH group (OTH: −49.8 ± 12.4 vs. O: −74.6 ± 18.1 mmHg). Furthermore, cardiac sympathovagal balance (LF/HF ratio), IL-10 and antioxidant enzymes were enhanced in OTH group. AP variability and baroreflex sensitivity were correlated with systolic AP, RPP, LF/HF ratio and inflammatory and oxidative stress parameters.ConclusionThe combination of HCTZ plus concurrent exercise training induced additional positive adaptations in cardiovascular autonomic control, inflammation and redox balance in ovariectomized SHR. Therefore, combining exercise and medication may represent a promising strategy for managing classic and remaining cardiovascular risks in AH.

Fabrication of avian eggshell membrane derived dispersed collagen hydrogels for potential bone regeneration
Authors: Aggarwal Aakriti , Sah Mahesh Kumar 
Published: August 2023

Abstract
Tissue engineering is emerging as an effective and alternate strategy for healing the impaired bones. This study reports the development of potential and novel bone tissue regenerating matrices from the avian eggshell membrane derived collagen dispersed in poly-(vinyl alcohol) (PVA). The concentration of the aqueous collagen dispersions within the PVA solution were varied from 0.5 % to 2 % (w/V); and the sols were subjected to varying freeze-thaw cycles to achieve gelation; leading to the fabrication of hydrogel matrices. The developed hydrogels were investigated for their physico-chemical characteristics through the ATR-FTIR, XRD, FESEM and biocompatibility measurements. The ATR-FTIR results showed the presence of amide A, amide I and hydroxyl groups; which were further reinstated by the XRD studies. The morphological and topological analysis of the different hydrogel groups was made through FESEM. It comprised of the measurements of pore dimensions ranging (3.98 ± 1.84 µm to 9.24 ± 5.55 µm), percentage porosity (47 %–97 %), and average surface roughness (21–39 µm); thus, indicating them to be analogous support systems for bone tissue regeneration. Further, L929 mouse fibroblasts grown over these support systems showed excellent cell viability, thus hinting towards its competitive features and application towards remedial bone regeneration.
No Effect of Forest Representations on State Anxiety, Actual and Perceived Noise
Authors: Korbmacher Max , Wright Lynn 
Published: August 2023

Abstract
Previous research indicates that nature and nature representations might have positive effects and noise negative effects on various facets of life, such as performance, perceived life quality, and physical and mental health. In this intervention, we observed whether posters showing a representation of nature (forests) can be used to reduce actual noise, perceived noise, and state anxiety in university library users. Measurements were taken twice daily for a 5-day period pre-intervention (before posters were installed) and again during the intervention, when posters were installed. No significant differences were found for perceived or actual noise levels or for self-report state anxiety levels between pre-intervention and intervention phase. Correlations between actual and perceived noise, and actual noise and state anxiety, were small in their magnitude and non-significant, with the exception of state anxiety and perceived noise during the intervention phase, suggesting a weak positive relationship. Finally, in hierarchical linear regression models, actual and perceived (overall and talking) noise and intervention phase were non-significant predictors of state anxiety. Small effect sizes of nature representations on state anxiety, as well as actual and perceived noise, suggest posters of forests to not be an effective intervention for anxiety and actual and perceived noise reduction in a university library.
Pierre Bourdieus Rechtsdenken
Authors: Kretschmann Andrea 
Published: August 2023

ZusammenfassungDen Ausgangspunkt dieses Beitrags bildet die Beobachtung, dass Bourdieus Rechtsdenken bislang nur einseitig zur Kenntnis genommen wird. In der Literatur gilt er in seiner rechtsbezogenen Analyse vor allem als Feldtheoretiker. Er steht in dieser Lesart für die Betrachtung eines Rechts, das – angereichert um eine Machtanalytik – entlang der Perspektive sozialer Differenzierung zu entschlüsseln sei. Dem wird im Beitrag eine Lesart gegenübergestellt, die Bourdieus analytischen Blick auf das Recht als Integration von einerseits sozialstruktureller und andererseits kultursoziologischer Perspektive aufschlüsselt. Eine solche Betrachtung, so wird argumentiert, vermag Bourdieus Mehrwert für die Rechtssoziologie umfänglicher zu verdeutlichen als bloß durch eine feldtheoretische Rezeption des Autors. Dieser begründet sich aus dem Potenzial, Subjekt- und Handlungsbegriff sowie Macht- und Herrschaftsverständnis innerhalb der Rechtssoziologie erneuern und differenzieren zu können.
O alcance do Absoluto pela Consciência mediante a Religião no "Prefácio" da Fenomenologia do Espírito de Hegel
Authors: Macedo Rodrygo Rocha 
Published: August 2023

O presente trabalho tenciona analisar, a partir do “Prefácio” da Fenomenologia do Espírito de Hegel, qual o papel da religião na condução da consciência ao Saber Absoluto, último e máximo nível de compreensão que o ser humano pode alcançar de si e do mundo. Para tanto, o trabalho ora apresentado indica o propósito de Hegel, a partir de uma descrição panorâmica do citado “Prefácio”, em situar a consciência e a religião dentro do sistema contido na Fenomenologia. Em seguida, é apresentada a posição da consciência no mundo, tensionada entre o desejo de apropriar-se do outro, de um lado, e o dever de reconhecê-lo, do outro. Com efeito, a pesquisa em comento demonstra que a religião oferece uma alternativa para resolver essa tensão entre consciências, propondo-lhes um equilíbrio social mediante o conceito de “comunidade”. Por fim, esta investigação debruça-se em como, na Fenomenologia, o Saber Absoluto, meta da consciência, está intimamente correlacionado com o conceito de Deus, que é o eixo da doutrina religiosa.

AbstractOver the past decade, ketamine, an NMDA receptor antagonist, has demonstrated fast-acting antidepressant effects previously unseen with monoaminergic-based therapeutics. Concerns regarding psychotomimetic effects limit the use of ketamine for certain patient populations. Reelin, an extracellular matrix glycoprotein, has shown promise as a putative fast-acting antidepressant in a model of chronic stress. However, research has not yet demonstrated the changes that occur rapidly after peripheral reelin administration. To address this key gap in knowledge, male Long–Evans rats underwent a chronic corticosterone (CORT; or vehicle) paradigm (40 mg/kg, 21 d). On day 21, rats were then administered an acute dose of ketamine (10 mg/kg, i.p.), reelin (3 µg, i.v.), or vehicle. Twenty-four hours after administration, rats underwent behavioral orin vivoelectrophysiological testing before killing. Immunohistochemistry was used to confirm changes in hippocampal reelin immunoreactivity. Lastly, the hippocampus was microdissected from fresh tissue to ascertain whole cell and synaptic-specific changes in protein expression through Western blotting. Chronic corticosterone induced a chronic stress phenotype in the forced swim test and sucrose preference test (SPT). Both reelin and ketamine rescued immobility and swimming, however reelin alone rescued latency to immobility.In vivoelectrophysiology revealed decreases in hippocampal long-term potentiation (LTP) after chronic stress which was increased significantly by both ketamine and reelin. Reelin immunoreactivity in the dentate gyrus paralleled the behavioral and electrophysiological findings, but no significant changes were observed in synaptic-level protein expression. This exploratory research supports the putative rapid-acting antidepressant effects of an acute dose of reelin across behavioral, electrophysiological, and molecular measures.

Published: August 2023

OBJECTIVES
Admissions to the ICU for children with hyperglycemic crisis (HGC, defined as diabetic ketoacidosis, hyperglycemic hyperosmolar syndrome, or hyperosmolar ketoacidosis) increased during the COVID-19 pandemic. We sought to identify if severity of illness for HGC also increased from prepandemic to pandemic years 1 and 2.

METHODS
Retrospective study of children aged ≤18 years hospitalized in the Pediatric Health Information System for HGC. Pre-COVID-19 years were defined as March 2017–February 2020, COVID-19 year 1 as March 2020–February 2021, and COVID-19 year 2 as March 2021–February 2022. The primary outcome was ICU admission. Secondary outcomes included mortality, length of stay, cost, and use of neurologic therapies, mechanical ventilation, or vasoactive support.

RESULTS
There were 46 425 HGC admissions to 42 hospitals, 20 045 (43.2%) of which were ICU admissions. In comparison with pre-COVID-19, children admitted in COVID-19 year 1 (odds ratio, 1.31 [95% confidence interval, 1.25–1.38], P &lt; .0001) and year 2 (odds ratio, 1.17 [95% confidence interval, 1.11–1.22], P &lt; .0001) had a higher odds of ICU admission in multivariable modeling after controlling for confounding variables. Severity of illness was higher during COVID-19 years when considering secondary outcomes, although these associations were not consistent across outcomes and year. There was no difference in mortality.

CONCLUSIONS
Children with HGC had a higher severity of illness during the pandemic which was sustained over 2 years. Reduction in social distancing and evolving variants of SARS-CoV-2 over the 2 years of the pandemic did not significantly alter the relationship between HGC and higher requirement for ICU care.
Green synthesis of silver nanoparticles using Sorghum bicolor var. technicum seed extract, their characterisation and investigation of biological activities
Authors: Dalgıç B. , Demir N. 
Published: August 2023

AbstractSynthesis of nanoparticles can be long and costly processes using physical and chemical methods. Biological synthesis of nanoparticles is known to be cheaper and easier than other methods. In this study, silver nanoparticles (AgNP) were obtained by biological synthesis, also known as green synthesis, using Sorghum bicolor var. technicum (Körn) Stapf ex Holland seed extract, popularly known as sorghum. AgNPs were characterised by SEM, EDS, TEM, FT-IR, and UV-Vis Spectroscopy. SEM images confirmed that the shape of AgNPs was spherical. TEM analysis showed that the average sizes of AgNPs ranged from 51 to 56 nm. EDS analysis confirmed the presence of AgNPs by detecting a silver ion peak at 3 KeV. UV-Vis spectroscopy analyses indicated that the brown-burgundy colour of AgNPs exhibited maximum absorbance at 450 nm. The biological activities of the extract and AgNPs were investigated through antimicrobial, antibiofilm, antioxidant, mutagenic, and DNA cleavage activity analyses. The extract exhibited the highest MIC value against Gram-positive bacterium Bacillus subtilis (0.62 μg mL−1), whereas AgNPs demonstrated the highest antimicrobial activity specifically against Gram-negative bacterium Escherichia coli (0.31 μg mL−1). The antibiofilm results revealed that the extract displayed the highest percentage of biofilm inhibition against B. subtilis, while AgNPs exhibited notable efficacy against both Candida albicans yeast and Pseudomonas aeruginosa bacterium. The antioxidant activities were evaluated using DPPH• and ABTS•+ methods, and it was determined that both samples had high antioxidant activity. Mutagenicity of the extract and AgNPs were evaluated by the Ames/Salmonella test using two strains of Salmonella typhimurium (TA98 and TA100). The mutagenic activity of the extract increased depending on the concentration for both strains, while AgNP did not show mutagenicity at any concentration. The agarose gel electrophoresis method showed that the extract and AgNPs cleaved DNA in the presence of an oxidising agent.

Published: August 2023

AbstractIn this study, a water-soluble novel polysaccharide called TPS was successfully prepared and isolated from Liubao tea. The optimal extraction conditions resulted in a yield of 10.70% for the crude TPS. The purified TPS exhibited unique physicochemical properties and structural characteristics. It was identified as an acidic polysaccharide with trace binding proteins, with a →4)-α-D-Galp-(1→) residue. The purified TPS had a dense and uneven appearance, potential crystallisation characteristics, and structural stability. Importantly, it demonstrated the ability to inhibit glucose transport in Caco-2 cells by down-regulating the expression of sodium/glucose cotransporter 1 (SGLT1) and glucose transporter 2 (GLUT2), leading to a hypoglycemic effect. These findings highlight the potential of TPS from Liubao tea as a functional food or additive with hypoglycaemic properties.
