The aim of this study was to know the effect of Mimosa pudica root extract on histopathological appearance of Rattus norvegicus brain induced by Naja sputatrix venom. Thirty rats were divided into 5 groups. There were 2 control groups and 3 treatment groups, which was given 250, 500, and 1000 mg/kg BW of Mimosa pudica root extract orally. The first 7 days each group was adapted to the environment. On the 8th day, the treatment was started by injecting Naja sputatrix LD50 (0,13 L/gram BW) IM in gluteus muscle, continued with giving Mimosa pudica root extract orally for the treatment groups 5 minutes after venom injection. 6 hours after the last treatment, rats were killed by cervical dislocation, injected with formalin 10% in the heart, then necropsied. Histopathological evaluation was done to score brain damage based on meningitis, perivascular cuffing, and necrotic cells using HE stain with 1000x magnification. The result showed 1000 mg/kg BW dosage of Mimosa pudica root extract can reduce brain damage based on meningitis, perivascular cuffing, and necrotic cells in Rat (Rattus norvegicus) caused by Naja sputatrix venom and gave significant difference (p < 0.05) among the treatment groups.

Authors: Usamah Usamah
Published: July 2022

Analyzing the profitability performance of Baitut Tamwil Muhammadiyah (BTM) in Central Java, Indonesia, is the purpose of this study to obtain certainty about the effect of the independent variable on the dependent variable from the data coverage period 2015-2019 using multiple regression analysis. The result indicated that two independentvariables, capital adequacy ratio (CAR) and operating expenses and operating income (BOPO), have relationships with profitability performance except for financial to deposit ratio (FDR) and non-performing finance (NPF). As for moderation variable genders, only the BOPO variable affects ROA significantly. Whereas the FDR, CAR, and NPFvariables are insignificant to the ROA variable. The results of this study are valuable for academics, BTM, and other stakeholders. The results of this study imply that BTM should pay more attention to the role of female managers who benefit BTM in their operational activities. From these results, the authors fill in the limited literature on the role of female managers in BTM in Central Java which has been around for a long time but has not received adequate attention. Due to the limited portion of the role of BTM managers and information on their achievements. This study produces relatively significant implications for BTM to give more roles for women to become managers in BTM for BTM progress.
INTERNAL AND EXTERNAL FACTORS AFFECTING ISLAMIC BANKS PERFORMANCE IN NIGERIA
Authors: Muhammad Aishatu Usman
Published: July 2022

The purpose of the paper is to analyze the internal and external factors affecting the performance of Islamic banking in Nigeria. The study is quantitative research that applies the generalized least square (GLS) regression to measure the effect of independent variables on the dependent variables. Data is generated from the published financial statements of the bank from the year of inception, 2012 to 2020. The dependent variables used to measure the performance are return on assets (ROA) and return on equity (ROE). The independent internal variables are measured using the financial deposit ratio (FDR) and operational efficiency ratio (OER), while the external factors are measured using gross domestic product (GDP) and inflation. The findings for the internal factors show that FDR has a positive and significant effect on performance, indicating the availability of liquidity when required by depositors. OER also showed a significant positive effect on ROA and ROE, meaning that high operational efficiency can increase efficiency and performance. Meanwhile, external factors, GDP, show a significant negative effect on performance, implying that an increase in GDP per person will increase population, decreasing real GDP. More so, inflation also showed a negative and significant effect on performance, which implies that when there is inflation, the Central Bank increases the interest rate to slow down the inflation rate. However, interest is not permissible in an Islamic bank's operation, hence not affecting its performance.
ZAKAT, INFAQ, SADAQAH ON MUSTAHIK INCOME TO REALIZE NO POVERTY IN INDONESIAN ZAKAT INSTITUTION
Authors: Jaenudin M , Herianingrum Sri
Published: July 2022

The issue of poverty has become a part of Sustainable Development Goals (SDGs). Islam believes poverty must be sought and given concrete solutions through philanthropic instruments such as zakat, infaq, and sadaqah (ZIS). However, ZIS management will be more optimal if implemented by the Amil Zakat Institution or Lembaga Amil Zakat(LAZ). Thus, this research aims to determine the role of ZIS on mustahik's income for realizing SDGs at the Indonesian zakat institution. The research uses a quantitative method with a comparative approach. The Wilcoxontest will test the data using a different test between mustahik's income before and after being given ZIS funds. In addition, this study also uses several SDGs' indicator metadata, measured through the mustahik's income. Respondents from this research study were mustahik of the ZIS funds provided by Lembaga Manajemen Infaq (LMI), a zakat institution, with a total of 355 respondents spread across the provinces of East Java, South Sumatra, Riau Islands, and South Kalimantan. The results show a difference in the income of LMI mustahik before and after being given ZIS funds. If viewed from the SDGs' indicator metadata perspective, the distribution and utilization of ZISbecome essential in realizing no poverty. The existence of LAZ has an essential role in supporting the SDGs, especially in the equitable distribution of income, and can be an instrument in alleviating poverty. However, suggestions for future research are the need for an approach other than income and also need to be measured using metadata other than the SDGs indicator no poverty.
Gut microbiota in sarcopenia and heart failure
Authors: Liu Chia-Feng , Tang W. H. Wilson
Published: July 2022

Sarcopenia is common in aging and in patients with heart failure (HF) who may experience worse outcomes. Patients with muscle wasting are more likely to experience falls and can have serious complications when undergoing cardiac procedures. While intensive nutritional support and exercise rehabilitation can help reverse some of these changes, they are often under-prescribed in a timely manner, and we have limited insights into who would benefit. Mechanistic links between gut microbial metabolites (GMM) have been identified and may contribute to adverse clinical outcomes in patients with cardio-renal diseases and aging. This review will examine the emerging evidence for the influence of the gut microbiome-derived metabolites and notable signaling pathways involved in both sarcopenia and HF, especially those linked to dietary intake and mitochondrial metabolism. This provides a unique opportunity to gain mechanistic and clinical insights into developing novel therapeutic strategies that target these GMM pathways or through tailored nutritional modulation to prevent progressive muscle wasting in elderly patients with heart failure.
Acoustic Needs of Older People in the Outdoor Environment of Residential Communities: A Case Study in China
Authors: Zhang Huayue , Kang Jian
Published: July 2022

This study examines the acoustic needs of older people in an outdoor environment to design outdoor spaces according to their needs. Using the grounded theory approach, we selected and interviewed 16 older people from four residential communities in China. The acoustic needs of older people in an outdoor environment are established in terms of sound preference, quietness, acoustic variability, acoustic comfort, subjective loudness, sound rhythm, sound clarity, and sound sensitivity. The findings show that older people (a) attach importance to quietness when considering sound preference, (b) prefer taking a walk in an overall quiet environment, although sometimes a lively environment, (c) chose to conduct their activities in an environment with low variation in sound, (d) rate the comfort of their overall acoustic environment highly, (e) show little need for subjective loudness as long as the sounds are not ones they dislike, (f) generally prefer relatively rhythmic sound sources, (g) did not have a significant need for sound clarity, and (h) are tolerant of outdoor acoustic environments and did not pay too much attention to certain sounds. These findings can provide direction for better outdoor space designs in communities, to suit older people, and to create age-friendly cities.
Study on the LQR Control of High-speed Elevator Car Horizontal Vibration Based on the Jumping Inertia Weight Particle Swarm Optimization
Authors: He Qin , Li Hua , Zhang Ruijun , Jia Tichang
Published: July 2022

To reduce the horizontal vibration of a high-speed elevator car caused by the excitation of a guide rail more effectively, a differential magnetic suspension active guide shoe based on the principle of the differential magnetic suspension actuator is designed. Then the dynamic model of the active vibration damping system of the elevator car is established and an LQR controller is designed to reduce the horizontal vibration of the car. To search the weighting coefficient matrix of the LQR controller more efficiently, an algorithm named Jumping inertia Weight Particle Swarm Optimization (JWPSO) algorithm is proposed, and the frequently used fitness function verifies the optimization effect of the JWPSO algorithm. The weighting coefficient matrix of the LQR controller is optimized using the JWPSO algorithm. Finally, the impact of the JWPSO algorithm-optimized LQR controller is verified by MATLAB. The simulation result shows that the designed active vibration controller can effectively attenuate the horizontal vibration of the elevator car, and the control effect is significantly better than the LQR controller optimized by the GA algorithm and the H-inf controller optimized by LMI. This paper provided a new method for horizontal vibration reduction of the high-speed elevator car.

Authors: Javed Wajiha , Atique Mehak , Övgün Ali
Published: July 2022

In this paper, we study the weak deflection angle using Gauss-Bonnet theorem and bounding greybody factor for electric and magnetic black holes in the background of nonlinear electrodynamics. Using Gibbons and Werner's approach, first we acquire the Gaussian optical curvature to use in Gauss-Bonnet theorem and calculate the bending angle for spherically symmetric electric and magnetic black holes in both non-plasma and plasma mediums in the weak field limits. Later, we calculate the rigorous bounds of the greybody factor for the given black holes. Furthermore, we look into the graphical behaviour of bending angles and greybody bounds at some specific values of multiple parameters as well as black holes charges. It is to be mention here that all the results for the electric and magnetic charged black holes solutions reduce into the Schwarzschild black hole solution in the absence of the black holes charges.
A Contrast Minimization Approach to Quantify and Remove Sun Glint in Landsat 8 / OLI Imagery
Authors: Fell Frank
Published: July 2022

Sun glint, i.e., direct solar radiation reflected from a water surface, negatively affects the accuracy of ocean color retrieval schemes if entering the field-of-view of the observing instrument. Herein, a simple and robust method to quantify the sun glint contribution to top-of-atmosphere (TOA) reflectances in the visible (VIS) and near-infrared (NIR) is proposed, exploiting concomitant observations of the sun glint’s morphology in the shortwave infrared (SWIR) characterized by reflectance contrasts typically higher than those resulting from other in-water or atmospheric processes. The proposed method, termed Glint Removal through Contrast Minimization (GRCM), requires high spatial resolution (ca. 10–50 m) imagery to resolve the sun glint’s characteristic morphology, meeting additional criteria on radiometric resolution and temporal delay between the individual band’s acquisitions. It has been applied with good success to a selection of Landsat 8 (L8) Operational Land Imager (OLI) scenes encompassing a wide range of environmental conditions in terms of observation geometry and glint intensity, as well as aerosol and Rayleigh optical depth. The method proposed herein is entirely image based and does not require ancillary information on the sea surface roughness or related parameters (e.g., surface wind), neither the presence of clear water areas in the image under consideration. Limitations of the proposed method are discussed, and its potential for sensors other than OLI and applications beyond glint removal is sketched.
Reconstructing the Three-Dimensional Structure of Loop Current Rings from Satellite Altimetry and in situ Data using the Gravest Empirical Modes Method
Authors: Meunier Thomas , Brunius Paula Perez , Bower Amy
Published: July 2022

The three-dimensional structure of Gulf of Mexico’s warm-core rings, detaching from the Loop Current, is investigated using satellite altimetry and a large set of ARGO float profiles. Reconstruction of the Loop Current rings (LCRs) vertical structure from sea surface height observations is made possible by the use of the gravest empirical modes method (GEM). The GEMs are transfer functions that associate a value of temperature and salinity for each variable pair {dynamic height;pressure}, and are computed by estimating an empirical relationship between dynamic height and the vertical thermohaline structure of the ocean. Between 1993 and 2021, 40 LCRs were detected in the altimetry and their three-dimensional thermohaline structure was reconstructed, as well as a number of dynamically relevant variables (geostrophic and cyclogeostrophic velocity, relative vorticity, potential vorticity, available potential energy and kinetic energy density etc.). The structure of a typical LCR was computed by fitting an analytical stream function to the LCRs dynamic height signature and reconstructing its vertical structure with the GEM. The total heat and salt contents and energy of each LCR were computed and their cumulative effect on the Gulf of Mexico’s heat, salt and energy balance is discussed. We show that LCRs have a dramatic impact on these balances and estimate that residual surface heat fluxes of -13 Wm−2 are necessary to compensate their heat input, while the fresh water outflow of the Mississippi river approximately compensates for their salt excess input. An average energy dissipation of O[10−10−10−9] Wkg−1 would be necessary to balance their energy input.

Authors: Ren Yong , Li Da , Chen Yuquan
Published: July 2022

A 9.4 T/400 MHz superconducting magnet with a warm bore of 60 mm is being designed. The 400 MHz NMR magnet is composed of 9 coaxial coils to generate a central field of 9.4 T. The magnetic field homogeneity is better than 4 ppm for 50 mm diameter spherical volume (DSV) and better than 1 ppb for 5 mm DSV. Three types of NbTi strands were used to reduce the cost of the superconducting materials. A preload with 80 MPa was exerted on the superconducting coils and over-banding with stainless steel was adopted to release the stress from the electromagnetic forces. The magnet will be operated in persistent mode with superconducting joints to reduce the field decay. The pulse tube cryocooler with a cooling capacity of 1 W at 4.2 K can be used to reduce the liquid helium evaporation and vibration during operation. The magnet will be equipped with Bi2223/AgAu HTS current leads to reduce the heat losses. In this paper, the design of the 9.4 T NMR superconducting coils, electromagnetic field calculations, and stress analysis of the superconducting coils were presented.

Authors: Pfisterer Julia Katharina , Rausch Constantin , Wohlfahrth Doreen , Bachert Philip , Jekauc Darko , Wunsch Kathrin
Published: July 2022

Overweight and obesity, including its prevalence and consequences reflect a leading public health problem. Studies have already shown that physical activity leads to a reduction in body weight in children and adults. However, the university setting has rarely been investigated. The aim of this review is therefore to examine and summarize the effectiveness of physical-activity-based interventions to reduce obesity and overweight in university students. Three databases (PubMed, Scopus & Web of Science) were searched for relevant studies published in English between January 2010 and February 2022. Quantitative studies, conducting a physical-activity-based intervention with overweight or obese university students and reporting changes in BMI, were included. Data were described in a narrative synthesis. Eleven of 16 included studies reported a significant reduction in BMI. However, all studies except one were able to demonstrate some BMI improvements, whereas all studies reported significant changes in at least one health-related indicator. Aerobic exercises were able to demonstrate the greatest reductions in BMI. This review is the first systematic presentation on the effectiveness of physical-activity-based interventions on overweight and obese university students. Future work should reconsider BMI as the primary outcome because it is prone to bias. More interventions are needed to improve strategies.
Coastal Upwelling in the Bay of Bengal: Role of Local and Remote Windstress
Authors: Ray Sthitapragya , Swain Debadatta , Ali M. M. , Bourassa Mark A.
Published: July 2022

Monsoon winds drive upwelling along the eastern coast of India during the south-west (SW) monsoons. These winds also provide alongshore windstress (AWS) resulting in positive cross-shore Ekman transport (ET) from late May to the end of September. While instances of high ET and sea surface temperature (SST) based upwelling index (UI_SST) were observed along different parts of the coast, UI_SST was weaker in the northern section in the earlier part of monsoon. This was even in the presence of maximum AWS and ET during the 10 years analysis period spanning January-2009 to December-2018. Additionally, negative sea surface height anomalies (SSHAs), typically associated with coastal upwelling, were observed only along the southern-most coast. An empirical orthogonal function (EOF) analysis revealed two coherent modes of SSHA variation. The first principal component (PC) showed a SSHA signature coincident spatio-temporally with the first downwelling Kelvin wave, closely associated with the equatorial zonal winds that drive coastal Kelvin waves. The third PC with a coastal SSHA pattern similar to the second upwelling Kelvin wave was associated with offshore ET along the northern part of the Indian east coast. Time series of the two PCs exhibited suppression of coastal upwelling by downwelling Kelvin waves during May-July along the northeastern coast of India. Local AWS driven ET was the primary driver of coastal upwelling with the weakening of the remotely forced Kelvin waves in August. A coherent mode consisting of negative coastal SSHA signature was excited in response to local AWS driven ET during the upwelling period. This study examined the spatio-temporal variability of SW monsoon coastal upwelling along the east coast of India and illustrated the role of equatorial windstress forced first downwelling Kelvin wave in suppressing upwelling in the northern part of the coast during early SW monsoon season.

Published: July 2022

Information on the nutritive value and in vitro fermentation characteristics of native shrubs in New Zealand is scant. This is despite their potential as alternatives to exotic trees and shrubs for sup-plementary fodder, and mitigation of greenhouse gas and soil erosion on hill country sheep and beef farms. The objectives of this study were to measure the in vitro fermentation gas production, predict parameters of in vitro fermentation kinetics and to estimate in vitro fermentation of volatile fatty acids (VFA), microbial biomass (MBM) and greenhouse gases of four native shrubs (Coprosma robusta, Griselinia littoralis, Hoheria populnea and Pittosporum crassifolium) and an exotic fodder tree species, Salix schwerinii. Total in vitro gas production was higher (p<0.05) for natives than S. schwerinii. Prediction using the single pool model resulted in biologically incorrect negative in vitro total gas production from the immediately soluble fraction of the native shrubs. However, the dual pool model better predicted in vitro total gas production and was in alignment with measured in vitro fermentation end products. In vitro VFA and greenhouse gas production from fermentation of leaf and stem material were higher (p<0.05), and MBM lower (p<0.05), for native shrubs com-pared to S. schwerinii. The lower in vitro total gas production, VFA and greenhouse gases produc-tion, and higher MBM of S. schwerinii may be explained by the presence of condensed tannins (CT), although this was not measured and requires further study. In conclusion, results from this study suggests that when consumed by ruminant livestock, the browsable native shrubs can provide adequate energy and microbial protein, and that greenhouse gas production from these species is within ranges reported for typical New Zealand pastures.

Visually impaired people encounter many impediments and challenges in their lives such as related to their mobility, education, communication, use of technology, and others. This paper reports the results of an online survey to understand the requirements and challenges blind and visually impaired people face in their daily lives regarding the availability and use of digital devices. The survey was conducted among the blind and visually impaired in Saudi Arabia using digital forms. A total of 164 people responded to the survey most of them using the VoiceOver function. People were asked about the use of smart devices, special devices, operating systems, object recognition apps, indoor and outdoor navigation apps, virtual digital assistive apps, the purpose (navigation, education, etc.) of and difficulty in using these apps, the type of assistance needed, the reliance on others in using the assistive technologies, and the level of satisfaction from the existing assistive technologies. The majority of the participants were 18 – 65 years old with 13% under 18 and 3% above 65. Sixty-five percent of the participants were graduates or postgraduates and the rest only had secondary education. White Cane, mobile phones, Apple iOS, Envision, Seeing AI, VoiceOver, and Google Maps were the most used devices, technologies, and apps used by the participants. Navigation at 39.6% was the most reported purpose of the special devices followed by education (34.1%) and office jobs (12.8%). The information from this survey along with a detailed literature review of academic and commercial technologies for the visually impaired was used to establish the research gap, design requirements, and a comprehensive understanding of the relevant landscape, which in turn was used to design smart glasses called LidSonic for visually impaired.

Authors: Tartila Muzayyana
Published: July 2022

From time to time, the amount of zakat, infaq, and sadaqah collected increases. Due to the fact that the collection of zakat, infaq, and sadaqah has not yet reached its full potential, it is crucial to study Muzakki's behavior on the fintech platform. This study expands on prior research by introducing new variables based on knowledge of internal and external factors. This study employed a qualitative approach. Nine samples were obtained through Muzakki from individuals who had paid zakat, infaq, and sadaqah through the fintech platform. This study's data analysis involved data reduction, data presentation, and conclusion drawing. According to research, Muzakkis have diverse motivations for selecting fintech platforms as payment methods for zakat, infaq, and sadaqah. They cited internal considerations as the primary reason for selecting the QRIS and CoopLink fintech platforms as zakat, infaq, and sadaqah payment platforms. Then, external factors are influenced by the workgroup that an individual joins and the surrounding environment. Regardless of the diversity of motivational factors in this study, all informants felt the same way when using the fintech platform to pay zakat, infaq, and sadaqah: curiosity and ease. And based on the findings of this study, it is possible to conclude that the selection of the appropriate payment method can influence the collection of zakat, infaq, and sadaqah.
Waqf Management: A Bibliometric Review

Published: July 2022

This study aimed to create a map of the evolution of waqf management research in indexed journals. This study analyzed keywords, topics, journals, and authors that were published in the Scopus database. This study focuses on a journal published between 2016 and 2021. This year was chosen because waqf management research has continued to advance since 2016. In addition, the scope of this study is restricted to three disciplines: social finance; economics, econometrics, and finance; and business, management, and accounting. There were a total of 93 articles that matched the year and topic criteria. Utilizing the Vosviewer application, the data is processed to determine the bibliometric mapping associated with the advancement of Waqf Management research. As indicated by the findings, the study's focus on waqf management has continued to evolve over the past six years. According to the results of the bibliometric analysis, the Waqf Management theme generates five clusters. Cluster 1 includes 15 topics. Cluster 2 includes 6 issues. Cluster 3 includes 4 issues. And Cluster 9 includes 2 issues. This study also demonstrates the need for further research on Waqf Management as a result of the proliferation of contemporary waqf products resulting from the development of waqf studies. This is necessary to preserve the integrity of the waqf and the management of waqf assets so that they remain within the sharia corridor. Since there isn't a clear way to tell if the performance of waqf institutions has gone up or down, one of the most important areas of research is the creation of performance criteria for waqf institutions.

Introduction:
SARS-CoV-2 gains cell entry via angiotensin-converting enzyme (ACE) 2, a membrane-bound enzyme of the “alternative” (alt) renin-angiotensin system (RAS). ACE2 counteracts angiotensin II by converting it to potentially protective angiotensin 1–7.
Methods
Using mass spectrometry, we assessed key metabolites of the classical RAS (angiotensins I–II) and alt-RAS (angiotensins 1–7 and 1–5) pathways as well as ACE and ACE2 concentrations in 159 patients hospitalized with COVID-19, stratified by disease severity (severe, n = 76; non-severe: n = 83). Plasma renin activity (PRA-S) was calculated as the sum of RAS metabolites. We estimated ACE activity using the angiotensin II:I ratio (ACE-S) and estimated systemic alt-RAS activation using the ratio of alt-RAS axis metabolites to PRA-S (ALT-S). We applied mixed linear models to assess how PRA-S and ACE/ACE2 concentrations affected ALT-S, ACE-S, and angiotensins II and 1–7.
Results
Median angiotensin I and II levels were higher with severe versus non-severe COVID-19 (both p < 0.05), demonstrating activation of classical RAS. The difference disappeared with analysis limited to patients not taking a RAS inhibitor. ALT-S in severe COVID-19 increased with time (days 1–6: 0.12; days 11–16: 0.22) and correlated with ACE2 concentration (r = 0.831). ACE-S was lower in severe versus non-severe COVID-19 (p < 0.001), but ACE concentrations were similar between groups and weakly correlated with ACE-S (r = 0.232). ACE2 and ACE-S trajectories in severe COVID-19, however, did not differ between survivors and non-survivors. Overall RAS alteration in severe COVID-19 resembled severity of disease-matched patients with influenza. In mixed linear models, renin activity most strongly predicted angiotensin II and 1–7 levels. ACE2 also predicted angiotensin 1–7 levels and ALT-S. No single factor or the combined model, however, could fully explain ACE-S. ACE2 and ACE-S trajectories in severe COVID-19 did not differ between survivors and non-survivors.
Conclusions
Angiotensin II was elevated in severe COVID-19 but markedly influenced by RAS inhibitors and driven by overall RAS activation. ACE-S was significantly lower with severe COVID-19 and did not correlate with ACE concentrations. A shift to the alt-RAS axis because of increased ACE2 could partially explain the relative reduction in angiotensin II levels.

It is axiomatic that castor (Ricinus communis L.) is an industrially important oil crop with wide use. Augmenting oil yield from seeds beyond a certain limit is challenging and cumbersome. Hence, it is imperative to improve the seed yield by breeding elite hybrids/varieties. Morphological description of 208 castor genotypic population for eight qualitative was carried out and considerable polymorphism existed among the collection. Maximum genotypes were R2 and R3 morphotypes because of the dominant nature of red stem color and blooming nature. K means clustering separated the genotypes into 20 clusters with Cluster 4 and 20 as well separated one. Cluster 4 could serve as female parent since the cluster was composed of pistillate lines and cluster 20 as male parent during hybridization. Path coefficient analysis supported the correlation coefficient that effective spike length and capsule weight showed high positive direct effects with seed yield. Also, the analysis revealed primary spike length and effective length of primary spike as the variables with the largest weightage. The first four components accounted for 75.95% of the variation cumulatively. The components were rotated with varimax rotation and the variability contribution was similar to the normal (76%). High communality values specified the reliability of the studied variables in explaining the total variation. Considering both cluster analysis and PCA, the genotypes SKP 84, DPC 19, JP 65, JC 3, JC 26, RG 27, ICS 210 and RG 3477 possessed immense value as parents in breeding varieties/hybrids to meet out the global oil demand.

Background: There are around 250 million adolescents in India. Adolescents are vulnerable to common mental disorders with depression and self-harm accounting for a major share of the burden of death and disability in this age group. Around 20 percent of children and adolescents are diagnosed with/ or live with a disabling mental illness. A national survey has found that suicide is the third leading cause of death among adolescents in India. The authors hypothesise that an intervention involving an anti-stigma campaign co-created by adolescents themselves, and a mobile technology based electronic decision support system will help reduce stigma, depression, suicide risk and improve mental health for high-risk adolescents living in urban slums in India.Methods: The intervention will be implemented as a cluster randomised control trial in 30 slum clusters in each of the cities of Vijayawada and New Delhi in India. Adolescents aged 10 to 19 years will be screened for depression and suicide ideation using the Patient Health Questionnaire (PHQ-9). Two evaluation cohorts will be derived – a high-risk cohort with elevated PHQ-9 score ≥ 10 and/or a positive response (score ≥ 2) to the suicide risk question on the PHQ-9, and a non-high-risk cohort comprising an equal number of adolescents not at elevated risk based on these scores.Discussion: The key elements that ARTEMIS will focus on is increasing awareness among adolescents and the slum community on these mental health conditions as well as strengthening the skills of existing primary healthcare workers and promoting task sharing. The findings from this study will provide evidence to governments about strategies with potential for addressing the gaps in providing care for adolescents living in urban slums and experiencing depression, other significant emotional or medically unexplained complaints or increased suicide risk/self- harm and should have relevance not only for India but also for other low-and middle-income countries.

precipitation forecasting is critical due to its use in flood and water resources studies. Numerical weather predictions have been extensively developed in recent years. Today, the world's leading meteorological centers have used these models in their meteorological forecasts. The TIGGE database (dataset) uses a number of these centers in its meteorological forecasts. The present study was conducted to evaluate the performance of numerical models (ECMWF, MeteoFrance, NCEP) available in the database to predict precipitation in the Poldakhtar basin. Also, the effect of bias correction methods (EZ, QM, Delta) on precipitation forecasting models is another goal of this research. The obtained results showed that most prediction models had the lowest RMSE at low altitudes and the highest value at high altitudes. Among the models used in this study, the ECMWF model had the lowest RMSE in other parts of the Poldakhtar basin compared to other models, while the NCEP model had the highest RMSE value. Also, the evaluation of the corrected precipitation showed that the EZ method was the best oblique correction method in the proximity of the predicted precipitation to the observed data. In contrast, the Delta method was superior in RMSE and CC index. However, all bias correction methods have improved the predicted precipitation values to an acceptable level, which increases the efficiency of the precipitation prediction models in the flood warning system.

Background: To evaluate the level of neutralizing antibodies(NAbs) after COVID-19 vaccination in patients suffered from liver dysfunction.Methods: In this cross-sectional study with longitudinal follow-up , a total of 137 patients and 134 healthy volunteers with full-course COVID-19 vaccination for more than 1 month were enrolled. Data of clinical characteristics , dates after vaccination and the types of vaccine were collected. Blood samples were collected for NAbs test when the patient was hospitalized, and some collected second time after treatment. Results: Both seropositivity and mean titer of NAbs in patients was significantly lower than that in healthy control(65.7% vs 80.60%; 3.954 vs 4.944 log2AU/ml ). The decrease of antibody titer in patients was significantly faster than that in healthy controls（-2.642 vs -0.9654 AU/ml per day). In multiple logistic regression analysis, more severe liver damage (odds ratio (OR): 0.30; 95% confidence interval (95%CI): 0.12–0.71; p=0.0067) and male (OR: 0.17; 95%CI: 0.06–0.46; p=0.0005)were significantly associated with reduction of the probability of NAbs seropositivity. Chronic liver status(β =−1.45; 95% CI: −2.13 to −0.76; p<0.0001) and male sex (β =−1.18; 95% CI: −1.73 to −0.64; p<0.0001) were significantly associated with higher NAbs titers. In 26 patients with liver failure, both the antibody seropositivity and titer did not decrease, but increased(before 53.8% vs after 84.6%; 3.553 vs 4.321 log2AU/ml)after artificial liver plasmapheresis.Conclusions: Compared with healthy people, the seropositivity and titer of NAbs after COVID-19 vaccination in patients with liver dysfunction were lower and the titer decreased faster. Male, severe liver injury and chronic liver status have increased risk of poor antibody responses, and artificial liver treatment does not reduce NAbs titers in patients with liver failure.

Multiple sclerosis is a neurodegenerative autoimmune illness. Because parasites influence the immune system, the purpose of this research was to see how toxoplasmosis affected MS symptoms in an animal model. This study was performed on 36 female Wistar rats. After the induction of MS and Injection of Toxoplasma gondii tachizoites simultaneously, clinical signs and weight of rats were recorded. Histological changes in brains were examined by hematoxylin and eosin staining. Finally, TNF-α and INF-γ were determined by ELISA technique. When compared to the control group, the incidence of MS clinical symptoms was considerably lower in the chronic toxoplasmosis group (P < 0.0001). When compared to the MS group, the MS with chronic toxoplasmosis group lost less weight (P < 0.0001). Furthermore, the histological studies showed higher cell density, less spongy tissue, more viable cells, and less pyknotic cells in MS with chronic toxoplasmosis group compared with MS group. TNF-α and INF-γ decreased in MS with chronic toxoplasmosis compared to the MS group. Our findings suggest that the chronic toxoplasmosis can reduce clinical symptoms in MS and prevent the destruction of cells by modulating the host immune system responses.
