Published: January 2023

Abstract

The present study, La0.7Sr0.3MO3 (M = Mn-, Co-, and Fe-) perovskite, has successfully been synthesized via two techniques; co-precipitation, and sol-gel auto-combustion. XRD, SEM, and EDX characterized the prepared samples. XRD and SEM showed that the as-prepared La0.7Sr0.3MnO3 and La0.7Sr0.3CoO3 have multiphase. La0.7Sr0.3FeO3, in comparison, is nanosized, has a single-phase perovskite, and has a rather homogenous particle size distribution. Additionally, EDX mapping analysis shows that all pieces are distributed uniformly. All calcined powders contain 100% LSF, more than 15% perovskite phase of LSC, 47% LSM, and other secondary phases such cobalt oxide, according to X-ray diffractometer results. At room temperature and magnetic field ± 20 kG. La0.7Sr0.3MnO3 exhibited weak ferromagnetic behaviour in a low magnetic field, whereas diamagnetic behaviour was seen in a high magnetic field. La0.7Sr0.3FeO3 samples behave as strong ferromagnetic. On the contrary, the photodegradation of La0.7Sr0.3MnO3 is 99% compared to 75% and 91% for other samples under UVA lights. The degradation rate for La0.7Sr0.3MnO3 is 0.179 higher, about 3.25 and 2.23, than the other samples. A La0.7Sr0.3MnO3 nanocomposite perform as a photocatalyst to enhance the efficiency of Methylene blue photodegradation.. This study boosts good UVA- photocatalysts with high efficiency for different kinds of dyes. Hence the catalyst possessed high stability and effieiency for continuous treatment of wastewater.

Abstract
Purpose
This study aims to investigate whether the expression levels of proteins involved in microRNA (miRNA) biogenesis vary in the early- and late-stage traumatic brain injury (TBI) patients and to evaluate its effect on prognosis.
Methods
Dicer, Drosha, DiGeorge Syndrome Critical Region 8 (DGCR8), Exportin5 (XPO5), and Argonaute2 (AGO2) levels were measured in the blood samples of moderate TBI patients collected 4 to 6 hours and 72 hours after the trauma and compared with the control group. Prognostic follow-up of the patients was performed using the Glasgow Coma Scale.
Results
There were no statistically significant changes in the expression of the miRNA biogenesis proteins Dicer, Drosha, DGCR8, XPO5, and AGO2 in patients with moderate TBI. However, the expression of Dicer increased in the patients of whose GKS scores and neurologic examination were improved, and the expression of AGO2 decreased in most of these patients. The Dicer expression profile was found to increase in patients discharged from the intensive care unit in a short time.
Conclusions
MicroRNAs and their biogenesis proteins may guide prognostic and therapeutic decisions for patients with TBI in the future.

Authors: Rojas Sergio , Medina-Medina Silvia , Torres-Navarro Karla 
Published: January 2023

Abstract
BACKGROUND
Vitrectomy and internal limiting membrane peeling has been the Gold Standard for macular hole treatment since the 90s with high closure rates for idiopathic macular holes, however those larger than 400 um or from other etiologies didn’t have such good outcomes. Over the years, different techniques were developed to increase anatomical and functional success rates, most of them using scaffold tissues; autologous retinal graft showed promising results in these cases, achieving higher closure rates and visual acuity improvement.
SUBJECTS AND METHODS
Observational prospective case series. 6 eyes treated with autologous retinal graft for complex macular holes were included. Baseline best corrected visual acuity (BCVA) and ocular coherence tomography (OCT) were collected. After 12 months of surgery, in all cases a complete ophthalmological examination, OCT, microperimetry, color vision and contrast sensitivity tests were performed at last follow-up.
RESULTS
6 eyes were included with a minimal diameter of 781.7 ± 157.4 um. Initial BCVA was 0.8 ± 0.1 logMAR; all eyes showed improvement or stability: 0.7 ± 0.2 (p: 0.455) at 12-months, that remained stable in most cases at the end of follow-up (p: 0.30), reaching an 83% anatomical and 67% functional success rates. Color vision tests were normal in most of the eyes with a mild tritanopia in one case, regarding contrast sensitivity 5 eyes showed improvement. Microperimetry show some generalized sensitivity loss and residual microescotomas, and fixation stability was variable.
CONCLUSIONS
Autologous retinal graft is an efficient technique for complex macular hole repair with good functional and anatomical outcomes.

Abstract
Aerial methane surveys of oil and natural gas systems have discovered large emissions, which are missing or vastly undercounted in official estimates. We integrate approximately one million aerial site measurements into regional emissions inventories, employing empirically-grounded emissions simulations to estimate small emissions. We infer emissions inventories for six regions in the United States comprising 52% of onshore oil and 29% of gas production over fifteen aerial campaigns. Total estimated emissions range from 9.63% [9.03%, 10.37%] of natural gas production, roughly nine times the US government estimate, to 0.75% [0.65%, 0.85%] in a high-productivity gas-rich region. Aerially measured emissions at 0.05%-1.44% of well sites contribute 50%-81% of total emissions in twelve of fifteen campaigns. The social cost of methane emissions from these measured regions is roughly $9.4 billion per year, in addition to roughly $1 billion in lost sales. This highlights the importance of incorporating comprehensive remote sensing surveys into emissions inventories and efforts to benchmark and reduce methane emissions.

Published: January 2023

Abstract

Introduction: Dual antiplatelet therapy (DAPT) with both aspirin and P2Y12 inhibitors in patients with ST-segment elevation myocardial infarction (STEMI) has been shown to be associated with better outcomes. Yet, there is uncertainty regarding the optimal timing for its initiation. We performed a systematic review and meta-analysis of evidence on pretreatment with P2Y12 inhibitors in combination with aspirin in patients with STEMI undergoing primary percutaneous coronary intervention (PCI).
Methods and results: We performed a systematic search of electronic databases Pubmed, CENTRAL, and Scopus until April 2022. Studies were eligible if they compared P2Y12 inhibitor upstream administration to downstream use in patients with STEMI submitted to PCI. Studies with patients receiving fibrinolysis or medical therapy only were excluded. Outcomes were assessed at the shortest follow-up available.
Out of 2491 articles, 3 RCT and 16 non-RCT studies were included, with a total of 79300 patients (66.1% pretreated, 66.0% treated with Clopidogrel). Pretreatment was associated with reduction in definite stent thrombosis (OR 0.59 [0.37-0.94]), all-cause death (OR 0.77 [0.60-0.97]), and cardiogenic shock (OR 0.60 [0.48-0.75]). It was also associated with a lower incidence of TIMI flow <3 pre-PCI (OR 0.78 [0.67-0.92]). However, incidence of recurrent MI was not significantly reduced (OR 0.93 [0.57-1.52]). Regarding safety, pretreatment was not associated with a higher risk of major bleeding events (OR 0.83 [0.75-0.92]).
Conclusion: Pretreatment with DAPT, including a P2Y12 inhibitor, was associated with better pre-PCI coronary perfusion, lower incidence of definite stent thrombosis, cardiogenic shock, and, possibly, all-cause mortality with no sign of potential harm encountered.
Coordinated change of PM2.5 and multiple landscapes based on spatial coupling model: a comparison between inland and waterfront cities

Published: January 2023

AbstractContext Landscape heterogeneity is closely related to the spatial differentiation characteristics of PM2.5concentration in urbanized areas. Exploring the changing coordination of landscape evolution and PM2.5change provides robust support for mitigating urban pollution. Previous studies mainly focused on a single landscape in a specific area, lacking a quantitative comparison of multiple landscape evolution and PM2.5concentration changes in different types of cities. Objectives This study aims to quantify how multiple landscapes evolution could affect PM2.5and compare whether and what kind of differences exist among such effects across various regions. Methods Taking two typical inland and waterfront cities in China as examples, this study uses exploratory spatial data analysis and spatial coupling models to compare and analyze the distribution of PM2.5and its coordinated changes with the multiple landscapes (i.e., green, blue, and gray), with townships as the basic unit. Results The PM2.5concentrations in Hohhot and Tianjin have evident differences in spatial concentration. Moreover, the coordinated changes of green landscape and PM2.5in the two regions show opposite trends owing to the effect of the natural background. The change of green landscape to other landscapes in Hohhot can increase PM2.5concentration, with a maximum increase of 2.04 µg/m3. However, this landscape evolution in Tianjin may inhibit PM2.5, particularly in the blue dominant, strong coupling area. Conclusions By comparing the changes in PM2.5concentration caused by multiple landscape evolutions, managers can take differentiated measures tailored to local conditions to provide information for urban planning strategies related to mitigating air pollution.

Abstract
Propofol is a short acting anesthetic which can be used in neurosurgery and interventional surgery requiring anesthesia or sedation. Previous studies have suggested that glutamate has a toxic effect on astrocytes, while propofol has a protective effect on brain function. However, their mechanisms have not yet been elucidated. To determine the protective effect of propofol on brain function, we isolated primary astrocytes from the cerebral cortex of 1-day-old rats. After 10 days of culture, primary astrocytes were divided into control group (group C), propofol group (group P), glutamate group (group G), propofol + glutamate group (group PG), propofol + glutamate + inhibitor group (group PGI), and inhibitor group (group I). We then used the CCK8 assay method to test the effect of glutamate and propofol on astrocyte activity, and Western blot analysis to determine the expression of Caspase-3, Bcl-2, Bax, and p90RSK proteins. Moreover, flow cytometry was used to detect the level of apoptosis. Results showed that the expression of p90RSK and Bcl-2 was up-regulated in group P, while the expression of p90RSK and Bcl-2 was down-regulated and the expression of Bax and cleave-caspase3 were increased in group G. The expression of p90RSK and Bcl-2 were increased, while the expression of cleave-caspase3 was decreased in the PG group compared to the G group. In addition, the expression of p90RSK and Bcl-2 was decreased after PD98059 pretreatment. These results suggest that glutamate has a toxic effect on astrocytes, and propofol may attenuate the neurotoxicity of glutamate by activating the p90RSK / Bcl-2 signaling pathway.

Abstract
EMONO is an equimolar mixture of oxygen and nitrous oxide and is considered a reference for dental care in children. Completion of dental treatment has usually been used as a criterion to assess EMONO treatment. However, patient-reported outcomes are needed because i) we treat vulnerable subjects, and ii) effects felt can impact dental care prognosis. The aim of this study was to describe the patients’ feelings during EMONO sedation for dental care, especially anxiolytic and analgesic effects. We conducted a national prospective observational multicentric study between September 2018 and June 2020 in 13 French university hospitals. Participants were children between 3 and 15 years of age requiring dental care under EMONO. We assessed i) the prevalence of complete achievement of therapeutic effects (analgesia and anxiolysis) and ii) associated factors using a mixed effects logistic regression. In total, 677 children were analyzed. Anxiolysis and analgesia were experienced by a large majority of patients (86.5% and 79.0%, respectively, and 73% for both effects experienced). Several factors were associated with complete achievement of therapeutic effects: the presence of expected effects (no loss of judgment and slight decrease in level of consciousness), the absence of agitation and distress, a positive perception of EMONO using the VAS and race. Our study characterized the patients who best benefit from the therapeutic effects (anxiolysis and analgesia) expected by EMONO during dental treatment. It is reassuring to observe that most sociodemographic characteristics and medical history do not seem to influence the effectiveness of care.
HPLC fingerprint of thirty seven hop granulates with antioxidant activity tests and chemometric calculations
Authors: Hawrył Anna , Hawrył Mirosław 
Published: January 2023

Abstract

Chemometric techniques (principal component analysis, PCA, hierarchical cluster analysis, HCA, partial least squares, PLS) were applied to compare and predict the antioxidant activity of hops based on chromatographic fingerprints. Besides, isoxanthohumol (IXH) was quantified in order to compare its content in hop extracts. Reversed phase-high performance liquid chromatography with diode array detection (RP-HPLC-DAD) was used to obtain chromatographic fingerprints. Isoxanthohumol was used as fingerprint marker and validation (linearity, accuracy, precision, robustness, limit of detection (LOD), limit of quantification (LOQ)) of HPLC was performed. The chemical similarity between samples was evaluated using PCA and HCA. The total phenolics was determined by Folin-Ciocalteu (F-C) test and the antioxidant activity was evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP). The highest antioxidant activity (DPPH and FRAP) was observed for Cascade, the highest phenolic content was for Callista and Halertauer Tradition. The high antioxidant activity by FRAP test was obtained for Cascade and Magnum. The fingerprints combined with the antioxidant activity were evaluated using the PLS.
EmoAtlas: An emotional profiling tool merging psychological lexicons, artificial intelligence and network science
Authors: Semeraro Alfonso , Vilella Salvatore , Mohammad Saif , Ruffo Giancarlo , Stella Massimo 
Published: January 2023

Abstract
This work introduces EmoAtlas as a computational framework extracting emotions and syntactic/semantic word associations automatically from texts. EmoAtlas implements a cutting-edge synergy of interpretable artificial intelligence (AI) and psychologically-validated lexicons. Our framework supports out-of-the-box emotion detection of 8 categorical emotions and syntactic network building in 18 languages. In the task of detecting emotions in human-labelled social media posts and news media articles, either in Italian or in English, EmoAtlas achieves performances analogous, or even superior (e.g., 70.2% precision for detecting joy in tweets), to state-of-art natural language processing techniques like BERT, RoBERTa, distillBERT and ALBERT (e.g., 67.9% precision for detecting joy in tweets). This performance comes with EmoAtlas being 12 times faster than BERT. In a psychometric task like reproducing human creativity ratings for 1,071 short stories, EmoAtlas and BERT obtain equivalent predictive power (ρ ≈0.495, p<10-4). Combining BERT's semantic features with EmoAtlas' emotional/syntactic networks of words, the cross-validated resulting AIs get substantially better at estimating creativity rates of stories (ρ ≈0.628, p<10-4). This indicates an interplay between the creativity of narratives and the semantic, emotional, and syntactic divergence of their words, pointing out how EmoAtlas and BERT-like models could be used in synergy in psychometrics. By outputting interpretable emotional profiles and syntactic networks, EmoAtlas can quantify how emotions are channelled through specific associations in texts, e.g., how did customers frame their ideas and emotions towards "beds" in hotel reviews? We release EmoAtlas as a standalone computational tool and discuss its impact in modelling texts as data, promisingly filling current research gaps in AI and cognitive science.

Published: January 2023

Abstract
traosseous hemangiomas are uncommon intrabony lesions, generally they present in the vertebral skeleton and the calvarium and facial bones with benign manifestations and can be divided into 4 types. However, capillary hemangioma of rib is rare and first reported on 2010, and there was no reported again. Herein we present a 67-year-old man with a capillary hemangioma of the ribs with malignant manifestations. He was diagnosed with lung adenocarcinoma in the left lower lobe and performed lobectomy through uniportal video-assisted thoracic surgery (VATS) on August 16, 2013. In the follow-up, the patient got the left chest pain and the imaging suggested a rib lesion with bone destruction on August 13, 2021, followed by successful costectomy on August 31, 2021, and the pathology finally confirmed as a capillary hemangioma of rib. On follow-up, the patient showing no evidence of recurrence. Findings in this patient may broaden the understanding of intraosseous hemangiomas of ribs.

Published: January 2023

Abstract
We present the Hebrew Essay Corpus: an annotated corpus of Hebrew language argumentative essays authored by prospective higher-education students. The corpus includes both essays by native speakers, written as part of the psychometric exam that is used to assess their future success in academic studies; and essays authored by non-native speakers, with three different native languages, that were written as part of a language aptitude test. The corpus is uniformly encoded and stored. The non-native essays were annotated with target hypotheses whose main goal is to make the texts amenable to automatic processing (morphological and syntactic analysis). The corpus is available for research purposes upon request. We describe the corpus and the error correction and annotation schemes used in its analysis. In addition to introducing this new resource, we discuss the challenges of identifying and analyzing non-native language use in general, and propose various ways for dealing with these challenges.

Authors: Shahid Md , Shanmuganantham T. , Kumar S. Ashok 
Published: January 2023

Abstract
In this paper, a unique metamaterial absorber is presented for L-band, S-band and C-band applications. The unit cell of the MMA is designed by a modified square-shape closed-loop resonator printed on top of a dielectric substrate and backed by a copper layer. The proposed structure is ultrathin having total thickness of the absorber is 2.836 mm. The used substrate is FR4 epoxy dielectric substrate (εr = 4.4, tanδ = 0.02) having thickness of 2.8 mm. The absorption performance of the absorber is investigated using Ansys hfss. The absorptions occur in L, S and C bands at 1.21, 3.64 and 5.30 GHz, respectively. Moreover, the average absorption remains above 90%. The MMA structure is unique and insensitive to the angle of incidence across a wide range due to its symmetric structure. It is suitable for various applications like aircraft surveillance, satellite navigation, and non-military radiolocation radars.
Greater soil contribution to vegetation growth in dry regions than in humid regions
Authors: ZHU XINRONG , Luo Xiangzhong , Liu Hongyan 
Published: January 2023

Abstract
The response of vegetation growth to soil moisture is mediated by soil properties, but how and to what extent soil properties affect the response have remained unclear. In this study, we first quantify the global patterns of soil contribution to vegetation growth by establishing a nonlinear vegetation-soil moisture response model. We find that soil properties primarily regulate the nonlinear vegetation-soil moisture response by adjusting the soil moisture optima (SMpoint), which was defined as the peak in a fitted unimodal model. The impacts of soil properties on SMpoint range from − 0.18 cm3/cm3 to 0.16 cm3/cm3. Significant soil impacts on vegetation growth can be positive or negative, depending on soil impacts on SMpoint. In dry regions (Aridity index < 0.65), by adjusting soil water use, soil properties explained 62% of the vegetation growth change on average, and the average change in vegetation growth driven by soil property impacts was only 21% of that in humid ecosystems. Linking soil properties to vegetation responses to soil moisture is important to improve our understanding of droughts and their soil determinants. The results of our study provide insights into the role of soil properties in influencing global vegetation soil water uses and a new framework to consider the impacts of soil properties in global vegetation models.
