Abstract
In recent years, environmental pollution and ecological destruction in mining area has seriously affected the health and survival of surrounding people. To explore the degree of heavy metal pollution in soil of mining areas and phytoremediation strategies, we chose soil and dominant plants in an abandoned gold mining area as the research object. In this study, Arsenic (As) content in soil and plants was measured. The As pollution degree in local areas was evaluated by using geo-accumulation index and potential ecological risk index. And, As content in plants was analyzed by using enrichment coefficient method. The results show that 1) The pulp deposition area has the most serious As pollution of soil and the largest potential ecological risk index. 2) The composition of the plant community in the study area is dominated by herbaceous plants, among which gramineous, composites and legumes are the dominant plant types in the vegetation community restoration in the mining area. 3) The geoaccumulation index is significantly negatively correlated with species diversity index, Shannon-wiener diversity index and Pielou species evenness index. 4) The As content in dominant plants ranges from 0.11 to 15.92 mg/kg. The plants with strong As enrichment ability are Erigeron annuus (L.) Pers., Periploca sepium Bunge, and Setaria viridis (L.) Beauv., which can be considered as As-tolerant plants. This study can provide a basis and reference for plant management of As pollution in local soil.

Abstract
Many animal feeds compete for resources with human food production. The current use of food system by-products and residues as feed could potentially be increased to reduce the competition. We gathered a harmonised global food system material flow database for crop, livestock and aquaculture production including the availability of food system by-products. This allowed us to analyse the potential to replace the food-competing feedstuff, here cereals, whole fish, vegetable oils and pulses, that currently account for 11% of total feed used globally, with available food system by-products. While considering the nutritional requirements in animal production, we found that the replacement could free food-grade feeds for human consumption and increase the current food supply in kcal by 11-17% (6-11% if the use of crop residues is not accounted for) and in terms of protein 11-15% (9-14%). Our results thus indicate that the increased feed use of by-products has considerable potential, particularly when used in combination with other measures, in the much needed transition towards more sustainable and circular food systems.

Abstract
The linkage between the land use/land cover (LULC) pattern and water quality is an emerging topic in multidisciplinary research. The LULC changes affect water quality in many ways. Change in the land use/land cover, especially urbanization leads to water quality deterioration. This study mainly focuses on the water quality in parts of the river Karamana, which flows through the Thiruvananthapuram urban area. The water quality parameters of six selected sites within the urban area were obtained. Physico-chemical and biological parameters of water quality were analysed for 2019 (pre-monsoon, monsoon, and post-monsoon). The water quality data obtained during the present study were used to characterize the built-up and other areas. Results have shown a distinct variation of parameters in the upstream region (less built-up) than that of the urban area (more built-up). The results have clearly demonstrated the indication of the effect of urbanization on water resources. The speedy development of urban built-up in Thiruvananthapuram city causing severe issues to the water regime in terms of its quality. The data shows that the water quality is poor in the pre-monsoon period in most of the areas. Though the worsening of water quality is limited to a few localized zones, the trend of the quality change is serious. It needs the attention and proper consideration of policy planners and decision-makers. Adequate effluent treatment facilities in the urban regions is the need of the hour to minimize pollution.

Abstract
Background

Studies on the level of acceptance of COVID-19 vaccines and the perception of COVID-19 were most prevalent in the developed countries while scarcity of such studies in developing countries and Nigeria in particular. Because the level of acceptance of COVID-19 vaccines and the perception of COVID-19 differs among citizens of different countries, this study examines the acceptance of Nigerians to the usage of the COVID-19 vaccine.
Methods

An online cross-sectional study was conducted, with the use of an e-questionnaire which was administered to respondents (Nigerians) in a form of an online survey with emphasis on COVID-19 vaccine acceptance. Logistic regression analysis was employed to achieve the study.
Conclusions

The Nigerian public COVID-19 vaccines acceptance was fairly low in Nigeria. The educated male respondents are most likely to accept the usage of the vaccine. Similarly, respondents who believed that vaccines are generally safe and those who were willing to pay for vaccines, after becoming widespread, were more likely to accept the COVID-19 vaccines. However, those above 35 years old and respondents who are employed were not likely to accept the vaccines except been mandated by the employers. Moreover, respondents that believed in the rumors surrounding the dynamics of COVID-19 as well as those that do not have assurance in any source of information regarding COVID-19 vaccines, may not accept the usage of the vaccine. This study found that the most reliable sources of information regarding the COVID-19 vaccines were reports from the media and reports from healthcare providers.

Published: November 2021

Abstract
Background Nonalcoholic fatty liver disease (NAFLD) is a common disease and it is commonly associated with obesity. Trimethylamine N-oxide (TMAO) is a metabolite of intestinal flora generated in liver by flavin-containing monooxygenase 3 (FMO3), which has been widely studied in cardiovascular diseases and obesity. However, the mechanism of TMAO reacted on liver remains unclear. This study aimed to determine TMAO activated hepatitis inflammation and lipid accumulation which was associated with nuclear factor kappa B (NF-κB) signaling pathway in vitro. ResultsThe present study showed that TMAO in 50μM markedly increased the LO2 cells function and decreased the cells inflammation. However, over the concentration of 200μM in TMAO, cells inflammation was increased and function was declined apparently. In addition, TMAO promoted lipid accumulation. Mechanistically, this change was accompanied by the activation of NF-κB signaling pathway. Furthermore, blocking NF-κB by SN50 was significantly increased in lipid accumulation and apoptosis. SN50 was markedly decreased the protein expression stimulating by TMAO.ConclusionsOverall, the result suggested that TMAO promotes cells inflammation and lipid accumulation in hepatocytes and it might be associated with NF-κB signaling pathway.

Abstract
Carlson trophic state index (CTSI) has been commonly adopted to assess the eutrophication potential of reservoirs or lakes in water quality management. This study aims to analyze the influencing factors of CTSI-based eutrophication by using Pearson correlation analysis and principal component analysis (PCA) with long-term data from 2008 to 2019 on 21 drinking water reservoirs in Taiwan. The trophic state index (TSI) deviation indicates that most drinking water reservoirs in Taiwan, around 45.5% of statistical data fall into non-algal turbidity with surplus phosphorus, especially in the spring and winter season. Besides, there are about 78 % of total collected data show that TSI (Chl-a) is less than TSI (SD) due to the small particulate predominance. On the other hand, three TSI variables (Secchi depth (SD), total phosphorus (TP) and chlorophyll-a (Chl-a)) of CTSI exhibits insignificant correlation to each other in most cases. At such a condition, the probability of eutrophication (TSI>50) based on TSI (SD) is 63%, while it is only as low as 20% based on TSI (TP) and TSI (Chl-a). The influencing factors of eutrophication variables by suspended solids (SS) composition and turbidity have shown that the SD is strongly influenced by non-algal SS. The deviations of three TSI have shown that the highest algae-induced eutrophication potential occurs in the summer season. In addition, the TP is the most significant loading factor of algae-induced eutrophication for drinking water reservoirs. It is concluded that the CTSI has limited applicability to identify the trophic status of drinking water reservoirs in Taiwan in the presence of sustainable non-algal turbidity comparative Chl-a that completely represents algal growth potential (AGP).
Higher-Order Semimetals and Chiral Hinge States in Topolectrical Circuit Model

Published: November 2021

Abstract
We propose a 3D topolectrical (TE) network that can be tuned to realize various higher-order topological gapless and chiral phases. We first study a higher-order Dirac semimetal phase that exhibits a hinge-like Fermi arc linking the Dirac points. This circuit can be extended to host highly tunable first- and second-order Weyl semimetals phases by introducing a non-reciprocal resistive coupling in the x − y plane that breaks time reversal symmetry. The first- and second-order Weyl points are connected by zero-admittance surface and hinge states, respectively. We also study the emergence of first- and second-order chiral modes induced by resistive couplings between similar nodes in the z-direction. These modes respectively occur in the midgap of the surface and hinge admittance bands in our circuit model without the need for any external magnetic field.

Abstract
Background

Total knee arthroplasty (TKA) outcomes are affected by many factors.This study aimed to evaluate whether changes in the posterior tibial slope (PTS) affects patients’ outcomes after cruciate-retaining TKA by affecting femorotibial articular contact kinematics.
Methods

Altogether, 20 knees in 10 patients who underwent posterior cruciate ligament-retaining TKA using the same size prosthesis for medial osteoarthritis were assessed preoperatively and 1 year postoperatively. PTS changes seen on lateral radiographs before and after TKA were calculated. Knees were placed in groups according to the PTS change at 1 year postoperatively (preoperative value − postoperative value). Group 1 had a >3° change and group 2 a ≤3° change. Knee kinematics under the weight-bearing mid-flexion condition were compared between the two groups via two-dimensional/three-dimensional registration. Pain was measured using the visual analog scale, and knee function was based on the Western Ontario and McMaster universities (WOMAC) osteoarthritis index and Knee Society Score (KSS) questionnaire results.
Results

Group 2 experienced paradoxical anterior motion of the mediofemoral condyle postoperatively, whereas group 1 did not. Comparison of TKA results between the two groups showed a significant between-group difference in pain and knee function of the KSS and in the WOMAC osteoarthritis index score (P ≤ 0.05). Postoperative results were better in group 1 than in group 2.
Conclusions

Achieving a greater change in the posterior tibial slope apparently improves outcomes in patients undergoing posterior cruciate ligament-retaining TKA because it reduces the paradoxical medial femoral condylar movement.

Published: November 2021

:
α-lipoic acid (ALA), also known as thioctic acid, is a biological thiol present in all types of prokaryotic and eukaryotic cells. It has been shown that ALA or its reduced form, DHLA, have several positive effects on human health acting as biological antioxidant, metal chelator and as a detoxifying agent. It is able to reduce oxidation of several antioxidant agents like glutathione, vitamins C and E, and to modulate insulin and NF-kB signaling pathways. ALA’s pharmacological effects are not only related to its antioxidant properties but it shows an anti-inflammatory action. In particular, ALA is able to reduce inflammasome activity, the pro-inflammatory cytokine levels, such as TNF-α, IL-1β, IL-6, IL-18 and IL-17, interferon (INF)-γ as well as the production of Vascular and Intercellular cell adhesion protein (VCAM-1 and ICAM-1). In recent papers, ALA has been indicated as a possible therapeutic approach to several endocrine or inflammatory disorders affecting female reproduction. Aim of the current review was to assess whether ALA has an evidence-based beneficial role on gynecological and obstetrical diseases such as polycystic ovary syndrome (PCOS), endometriosis, and miscarriage.

Published: November 2021

Life for married college students can indeed be very tedious and challenging. But with perseverance, good support system, and proper motivation these students will be able to cope well with the issues they face at present. This study elucidates the dominant lived-experiences of married college students valuing the resiliency theory. Qualitative study was employed, back up with triangulation to substantiate the theory used in the study. The study is deemed to denude the lived-experiences of married students while they are studying in a private or public universities in Region 02. To assess resiliency, the tool Cannor- Davidson Resilience Scale was also made use to measure the strength of these students while taking a risk in their lives. In this study, it revealed that married students are even stronger while they are facing tribulations in their respective lives. They even gamble their future but still optimistic enough to face whatever future may give them. Married students were able to exhibit compassion and empathy, resourceful and flexible and they show concern to everyone. One great thing that had been uncovered was that married students were problem solvers and critical thinkers.

This study aimed to discover the school principal instructional leadership influence on job satisfaction of vocational high school teachers in Sleman Regency, D.I. Yogyakarta. This type of research was ex-post facto with a quantitative approach. The questionnaire was conducted on 91 teachers (71,09% response rate) to examine the influence of principal instructional leadership (X) on teacher job satisfaction (Y). Validation of the instrument used expert judgment and empirical test with the Pearson Product Moment correlation, 43 out of 43 items are declared valid. The instrument reliability test was applied by using Cronbach's Alpha. The results of the reliability test showed that all variables were declared reliable (α 0,7). A classical assumption test was done by testing normality, linearity, multicollinearity, and heteroscedasticity. Simple linear regression was used as data analysis to test the influence of the independent variable (X) towards the dependent variable (Y). The simple linear regression results indicate a positive and significant influence between the principal instructional leadership on teacher job satisfaction (t = 13,329, p = .000). The coefficient of determination value (R^2) of 0,666 indicates that the principal instructional leadership influences teacher job satisfaction by 66,6%. Meanwhile, the remaining 33,4% are influenced by other factors.

Published: November 2021

Objective: This study aimed to design a valid questionnaire to evaluate knowledge, attitude, and practice (KAP) of Mashhad Dental school staff about oral health care and to assess the validity and reliability of this instrument.
Methods: The "Dental Staff Awareness of Oral Health Careâ€ (DSAOHC) was divided into three concepts; knowledge, attitude and practice. Ten experts of Mashhad Dental School contributed to design the questionnaire and assessed the face and content validity (I-CVI and S-CVI/AV) in two rounds. The necessity of each item was evaluated according to Lawsheâ€™s Content Validity Ratio (CVR). Construct validity, internal consistency, and reliability were assessed using confirmatory factor analysis, homogeneity coefficients, and test-retest by distributing the instrument among 207 dental staff working in other dental schools and private clinics.
Results: Based on the acceptable results of I-CVI, S-CVI/AV (>0.7), and CVR (> 0.62), the final version of DSAOHC was approved with 34 questions, including 10 questions about background information, 8 questions for the knowledge, 5 questions for attitude and 11 questions related to practice. Cronbach's alpha coefficients were acceptable for all domains. The RMSEA criterion was â‰¤ 0.05 and its upper band confidence interval (CI 90%) was â‰¤ 0.1. Also, CFI indicated the suitability of the model (the desired value of CFI> 0.9). Inter-Class Correlation/ICC revealed the appropriate measure (ICC=0.998).
Conclusion: The measures showed that this instrument is valid and reliable, also culturally adjusted to and acceptable for this community. It may adequately evaluate staffsâ€™ knowledge, attitude, and practice toward oral health.
We are what we eat, plus some per mill: Using stable isotopes to estimate diet composition in Gyps vultures over space and time.

Published: November 2021

1. Dietary studies in birds of prey involve direct observation and
examination of food remains at resting and nesting sites. Although these
methods accurately identify diet in raptors, they are time-consuming,
resource-intensive, and associated with biases from the feeding ecology
of raptors like Gyps vultures. Our study set out to estimate diet
composition in Gyps vultures informed by stable isotopes that provide a
good representation of assimilated diet from local systems.
2. We hypothesized that differences in Gyps vulture diet composition is
a function of sampling location, and that these vultures move between
Serengeti National Park and Selous Game Reserve protected areas to
forage. We also, theorised that grazing ungulates are the principal
items in Gyps vulture diet.
3. Through combined linear and Bayesian modelling, diet-derived from
13C in Gyps vultures consisted of grazing herbivores across sites, with
those in Serengeti National Park consuming higher proportions of grazing
herbivores (> 87%). 13C differences in vulture feather
subsets did not indicate shifts in vulture diet and combined with blood
13C, vultures fed largely on grazers for ~159 days
before they were sampled. Similarly, 15N values indicated Gyps vultures
fed largely on herbivores. 34S ratios separated where vultures fed when
the two sites were compared. 34S variation in vultures across sites
resulted from baseline differences in plant 34S values, though it is
not possible to match 34S to specific locations.
4. Our findings highlight the relevance of repeated sampling that
considers tissues with varying isotopic turnover and emerging Bayesian
techniques for dietary studies using stable isotopes. Findings also
suggested limited vulture movement between the two local systems.
However, more sampling coupled with telemetry is required to fully
comprehend this observation and its implications to Gyps vulture ecology
and conservation.
