Molecular diversity of Protura in southern High Appalachian leaf litter
Authors: Caterino Michael , Recuero Ernesto
Published: November 2023

The higher elevations of the southern Appalachian Mountains, U.S.A., host a rich, but little-studied fauna of Proturan hexapods. Here, we publish 117 Proturan barcode sequences from this region, estimated by automated species delimitation methods to represent 72 distinct species, whereas only nine species have previously been reported from the region. Two families, Eosentomidae and Acerentomidae, co-occur at most sampling sites, with as many as five species occurring in sympatry. Most populations exhibit very low haplotype diversity, but divergences amongst populations and amongst closely-related species are very high, a finding common to other phylogeographic studies of Proturans. Though we were unable to identify any of the barcodes to species, they form a useful, if preliminary, glimpse of southern Appalachian Proturan diversity.
Optimizing analgesic pain relief time analysis through Bayesian and non-Bayesian approaches to new right truncated Fréchet-inverted Weibull distribution
Authors: Nader Nora , Ramadan Dina A. , Ahmad Hanan Haj , El-Damcese M. A. , El-Desouky B. S.
Published: November 2023

This research introduces a novel right-truncated distribution, termed the right truncated Fréchet-inverted Weibull distribution, and elucidates its mathematical properties including density, cumulative, survival and hazard functions. Various statistical attributes such as moments, quantile, mode and moment-generating functions are explored. These properties indicate the efficiency in modeling pain relief time for patients and the number of recoveries of Leukemia patients. Furthermore, estimation techniques, including maximum likelihood and Bayesian methods, are applied to progressive type-Ⅱ right-censored samples to derive parameter estimation of the proposed distribution. Asymptotic properties are employed to approximate confidence intervals for both reliability and hazard functions. Bayesian estimates are refined using both symmetric and asymmetric loss functions. The suitability of the proposed estimation methodologies is validated through simulation studies. The theoretical framework is applied to two real-world lifetime data sets, thereby substantiating their practical utility in medical areas.
Some properties of $ n $-quasi-$ (m, q) $-isometric operators on a Banach space
Authors: Gherairi Khadija , Hajjej Zayd , Li Haiyan , Regeiba Hedi
Published: November 2023

In this paper, we introduced the class of $ n $-quasi-$ (m, q) $-isometric operators on a Banach space. Such a class seems to be a natural generalization of $ m $-isometric operators on Banach spaces and of $ n $-quasi-$ m $-isometric operators on Hilbert spaces. We started by giving some of their elementary properties and studying the products and the power of such operators. Next, we focused on the dynamic of a $ n $-quasi-$ m $-isometry. More precisely, we proved a result by characterizing the supercyclicity of such a class.

Les territoires ultra-marins français sont quasiment tous concernés par le risque tsunami. Mayotte n’échappe pas à cet aléa majeur, et aux risques induits par d’importants enjeux situés sur sa bande littorale. Depuis 2018, du fait de l’activité sismo-volcanique liée à l’apparition d’un nouveau volcan sous-marin (Mont Fani Maoré), plusieurs simulations de tsunamis ont été produites sur Mayotte. Elles ont permis de dimensionner des plans d’évacuation validés par les autorités. Les capacités d’évacuation, mais aussi d’alerte, ont pu ensuite être évaluées et discutées, en modélisant à la fois les délais de mise en sécurité des populations et l’audibilité théorique des sirènes. Mayotte s’engage ainsi dans la gestion du risque tsunami mais la préparation des populations doit rester une priorité afin de réduire les délais d’évacuation malgré des difficultés inhérentes à toute nouvelle stratégie de prévention.
Marie-Galante (Guadeloupe) à l’épreuve des sargasses : approches anthropologique et géographique d’un risque vécu
Authors: Ménez Florence , Ranély Vergé-Dépré Colette , Béchacq Dimitri
Published: November 2023

Depuis 2011, comme ailleurs dans la Caraïbe, l’île de Marie-Galante (archipel de la Guadeloupe), et singulièrement la commune de Capesterre-de-Marie-Galante, est touchée par l’afflux massif et discontinu d’algues sargasses. Confrontés à un même phénomène, les habitants de Capesterre élaborent pourtant des représentations divergentes et dynamiques de ces transformations successives du littoral. Nous questionnerons ici l’élaboration de divers registres de mémoires du risque et leur articulation avec les recompositions socio-spatiales induites par cet aléa. Cet article se fonde sur des matériaux ethnographiques produits pendant le projet pluridisciplinaire, citoyen et artistique SaRiMed sur les dynamiques des modes de vie et les incidences sur la santé des habitants des Antilles françaises.
La mémoire du risque à Mayotte, un atout pour la prévention des risques naturels ?
Authors: Rullier Mathilde , Hubert Gilles
Published: November 2023

Dans un contexte global de dérèglement climatique, Mayotte, territoire insulaire de l’Océan Indien et récent département et région d’outre-mer (DROM), voit sa population fortement exposée aux multiples risques naturels. Mais, ce territoire doit faire face à de nombreux défis tout en répondant aux urgences. La politique gestion des risques naturels déployée sur le territoire hérite des cadres national et européen, mais la culture du risque se construit localement. Malgré des événements météorologiques marquants anciens, des flux migratoires élevés et un contexte radicalement différent de celui de la Métropole, la mémoire des habitants peut se révéler un atout à mobiliser pour ancrer une culture du risque territorialisée et adaptée aux enjeux actuels.

Authors: Islam Md. Shafiqul , Shafiq Ummul Fatiha Binte
Published: November 2023

Coastal environment is a complex term in relation to definition, context, and importance. Fisher women do not get recognition and importance in the social realm. This study was conducted with aims to explore the role of fisher women in preserving coastal environment and what challenges they face. Both qualitative and quantitative data were used in this study. Direct engagement of women in coastal fishing is hard to find, but the indirect involvement of women is remarkable. They are involved in multiple tasks, including fish drying, cleaning, sorting, storage, packing, net maintenance, grading, and collection. Several livelihood activities get narrowed, and fisher women suffer more. They face several problems and live with disasters in the coastal environment. The poor fisher women often settle in the risky areas. Fishing activities are often low-income, but they stopped different livelihood activities for environmental shocks. They initiated new livelihood options switching from fishing.
The Lived Experiences of African Americans in International Education
Authors: Brown Arthur Conan
Published: November 2023

The purpose of the contents of this chapter is to explore the lived experiences of African American teachers who chose to work in international schools, while at the same time discussing the reasons that the number of these teachers is so low in comparison to those of their counterparts of European descent. While African Americans make up over 13% of the American population, they only make up about 7% of the nation's teacher pool. When this is narrowed down to those who chose to teach internationally, the disparity in the number between the races becomes even greater. Although there are no statistics kept on the number of African Americans working in international schools, data collected through conversations with African Americans who are engaged in international teaching tends to show that the number of African Americans in international schools is very low. This chapter will examine the beliefs of those who are working abroad as to why they believe that this is the case.
Understanding the Lived Experiences of Lower School Students in Virtual Education During the COVID-19 Pandemic
Authors: Schmidt Raymond John
Published: November 2023

This chapter is an original summary of the qualitative research results investigating the closing of on-campus schooling due to the COVID-19 pandemic which led to the need for lower schools to implement virtual education. The critical issue investigated was the negative impacts on student learning that resulted from lower school students learning virtually. The phenomenon in this investigation was the lower school virtual education lived experiences caused by the COVID-19 pandemic. This chapter focuses on the experience itself and how experiencing something is transformed into consciousness. This study is particularly important because the implementation of virtual education as a result of the COVID-19 pandemic swiftly and radically altered the field of mainstream PreK-12 schooling in 2020 and still does today. The results of this investigation provide global trend guidance to school leaders and other stakeholders who are considering virtual education as an option for lower school students.

An Examination of International School Onboarding Programs
Authors: Anning Graeme Argirios
Published: November 2023

This chapter will examine the pre-arrival, arrival and orientation, and transition phases of international school onboarding programs. The elements are the social media group, internet platform, airport protocol, arrival dossier, orientation schedule, events itinerary, and transition partnership. The phases were delineated based on a robust literature review and Klein and Heuser's inform-welcome-guide framework. The elements were created in alignment with the adult learning principles put forth by Knowles et al. and the concept of fulfilling a newcomer's psychological contract. The three phases and seven elements of the international school onboarding program are substantiated and moderately substantiated using the Delphi method. International school leaders, educators, and coordinators can use the findings to create a site-specific onboarding program.

Shifting Linguistic Landscapes Within the Context of International Schools
Authors: Heidt Esther Bettney , Nordmeyer Jon
Published: November 2023

This chapter explores critical issues concerning multilingualism within the context of international schools. As international educators re-imagine and re-create more equitable approaches to language education, three significant conceptual shifts about multilingual education are emerging: 1) international educators demonstrate mindsets which value multilingualism over monolingualism, 2) school communities recognize more expansive and dynamic conceptualization of linguistic identities, 3) multilinguals' diverse languaging practices are valued over previously standardized views of languages. The authors outline some of the key debates related to these significant shifts, including potential conflicts between various stakeholders. The chapter challenges international schools to use their resources and autonomy to enact positive social change for multilingual learners, their families, and their communities. Finally, the chapter concludes with a robust research agenda to explore more equitable and innovative approaches to language education within the context of international schools.
A Metaverse-Based Approach to Rehabilitation Healthcare
Authors: Vivekitha V. , Caroline Vinnetia S. , Sri Roshini R.
Published: November 2023

Rehabilitative healthcare is focused on restoring physical and cognitive abilities in individuals following injuries or diseases and has largely relied on traditional methods such as physical therapy and medical interventions over time. However, the metaverse, a collaborative virtual environment, has opened new possibilities for the field of rehabilitation. In comparison to traditional rehabilitation, this technology provides increased accessibility and convenience by allowing individuals to participate in therapy from the comfort of their own homes. The immersive and engaging nature of virtual reality (VR) and augmented reality (AR) technologies increases patient motivation and compliance with therapy regimens. Through the integration of telemedicine, wearable technologies, and artificial intelligence, rehabilitation can become more sophisticated and personalized. The use of these technologies can enable the acquisition, analysis, and tracking of patient data, as well as providing real-time feedback for the improvement of treatment regimens and outcomes.

Authors: Sharma Aman , Kaushal Archit , Dogra Kartik , Mohana Rajni
Published: November 2023

A significant complication of diabetes mellitus, diabetic foot ulcers (DFUs), can have devastating repercussions if they are not identified and treated right away. Machine learning algorithms have gained more attention recently for their potential to anticipate DFUs before they manifest, enabling early management and preventing consequences. In this chapter, the authors examine how convolutional neural networks (CNNs) can be used to forecast DFUs. The performance of DenseNet, EfficientNet, and a regular CNN are specifically compared. With labels identifying the presence or absence of a DFU, the authors use a dataset of medical photographs of diabetic feet to train each model. The objective is to assess the effectiveness of these models and look at how each layer affects the precision of the predictions. The authors also hope to provide some light on how the algorithms are able to pinpoint foot regions that are most likely to get DFUs. They also look into how each CNN model's different layers affect prediction accuracy.

Telemedicine has the ability to alter healthcare delivery and enhance access to treatment for patients in rural and underserved locations. However, there are significant barriers to mainstream telemedicine adoption and implementation, including data privacy and security, funding, and the need for standardization. The authors review telemedicine's current situation and future potential by discussing new technologies that will shape the future of telemedicine, such as 5G networks, augmented and virtual reality, and wearable gadgets. Then the chapter discusses the growing use of telemedicine and its role in improving access to healthcare in rural and underserved areas. In addition to discussing the benefits for telemedicine, the chapter delves into the problems and limits that must be solved before it may achieve its full potential. Finally, it analyzes the future of telemedicine, including prospective uses and interaction with traditional healthcare systems.
Enhancing Creative Performance
Authors: Herbst Tobias D. , Hausberg J. Piet
Published: November 2023

The COVID-19 pandemic has disrupted firms' prior working modes. As more employees are required to work from home, firms need to successfully implement remote working and distance learning conditions. In this context, knowledge management systems (KMSs) are helpful in sharing knowledge and enhancing employee creativity, regardless of their place of work. This study elucidates the antecedents that moderate the impact of KMS usage on employees' creative performance. It explores how absorptive capacity (AC), as well as extrinsic and intrinsic motivation, directly influences employees' creative performance and their moderating effects. Results from an online survey of 415 employees indicate that KMS usage increases employees' creative performance. Moreover, AC as well as extrinsic and intrinsic motivation have a positive direct effect on employees' creative performance. However, the authors find no positive moderating effect of AC or extrinsic and intrinsic motivation on the relationship between KMS usage and employees' creative performance.

Authors: Cicek Ozlem Erdas
Published: November 2023

The accuracy of decision-makers in making managerial decisions and applying these decisions in uncertain environments will increase with the use of decision-making tools often and effectively. Machine learning, as one of these tools, provides a more effective definition of uncertainty conditions in the use of data in decision-making processes, on the basis of artificial intelligence. The rapid development of machine learning techniques enhances the Smart working models to help employees to execute functional jobs by processing information into each workflow. The change in business operations during and after the Covid-19 outbreak will enable machine learning techniques to be used more in predicting uncertainty. This attempt will be beneficial in pointing out new research trends of machine learning in the business context for the future.

Authors: Rao D. Sanjeeva , Rao M. Srinivasa , Rao V.V.S. Kesava
Published: November 2023

Road deaths and injuries highly affect the lives of people worldwide. road injuries and deaths happen due to improper driving, unfit motor vehicles, traffic laws disobeying persons and poor road condition. An effort is made here to assess the factors of poor road conditions which can be improved by prioritizing. Multi criteria technique is applied to prioritize the factors. Ann technique is adopted to assess the road condition. The methodology suggested can be used to determine the level of contribution of parameters towards safety hazard. Accordingly, appropriate mitigation measures may be adopted. A further detailed study needs to be conducted on a large scale by carrying out sensitivity analysis to test the stability of the ranking obtained by the suggested methods.
More Ramsey theory for highly connected monochromatic subgraphs
Authors: Hrušák Michael , Shelah Saharon , Zhang Jing
Published: November 2023

An infinite graph is said to be highly connected if the induced subgraph on the complement of any set of vertices of smaller size is connected. We continue the study of weaker versions of Ramsey’s theorem on uncountable cardinals asserting that if we color edges of the complete graph, we can find a large highly connected monochromatic subgraph. In particular, several questions of Bergfalk, Hrušák, and Shelah (2021, Acta Mathematica Hungarica 163, 309–322) are answered by showing that assuming the consistency of suitable large cardinals, the following are relatively consistent with ZFC:

•

$\kappa \to _{hc} (\kappa )^2_\omega $
for every regular cardinal
$\kappa \geq \aleph _2$
,

•

$\neg \mathsf {CH}+ \aleph _2 \to _{hc} (\aleph _1)^2_\omega $
.

Building on a work of Lambie-Hanson (2023, Fundamenta Mathematicae. 260(2):181–197), we also show that

•

$\aleph _2 \to _{hc} [\aleph _2]^2_{\omega ,2}$
is consistent with
$\neg \mathsf {CH}$
.

To prove these results, we use the existence of ideals with strong combinatorial properties after collapsing suitable large cardinals.
The spectrum of self-adjoint extensions associated with exceptional Laguerre differential expressions
Authors: Frymark Dale , Kelly Jessica Stewart
Published: November 2023

Exceptional Laguerre-type differential expressions form an infinite class of Schrödinger operators having rational potentials and one limit-circle endpoint. In this manuscript, the spectrum of all self-adjoint extensions for a general exceptional Laguerre-type differential expression is given in terms of the Darboux transformations which relate the expression to the classical Laguerre differential expression. The spectrum is extracted from an explicit Weyl

m

-function, up to a sign.

The construction relies primarily on two tools: boundary triples, which parameterize the self-adjoint extensions and produce the Weyl

m

-functions, and manipulations of Maya diagrams and partitions, which classify the seed functions defining the relevant Darboux transforms. Several examples are presented.
Application of Lagrange inversion to wall-crossing for Quot schemes on surfaces
Authors: Bojko Arkadij
Published: November 2023

Motivated by my work on enumerative invariants for Quot schemes, I related two power series obtained by two different means. One of them was computed using geometric arguments via virtual localization methods and the other one came from working with representation theoretic objects called vertex algebras. In this note, I give proof of the equality of the two power series by relying only on techniques related to Lagrange inversion. This makes my work on Quot schemes independent of the previous results in the literature and proves a new combinatorial identity.

BACKGROUND: Increased blood eosinophil count (BEC) is common in patients under dupilumab treatment for chronic rhinosinusitis with nasal polyps (CRSwNP). This study investigated the prevalence and consequences of hypereosinophilia and to help define patients at risk. METHODS: Real-life, prospective observational cohort study of patients treated with dupilumab for severe CRSwNP. Eligible patients were adult and biological-naïve (N=334). All BEC values at baseline and during treatment were reported. Patients with a follow-up of ≥ 1 year were included to define patients at risk for hypereosinophilia by comparing baseline BEC values (N=218). Furthermore, clinical characteristics and therapeutic consequences for patients with BEC ≥ 3.0 were noted. RESULTS: Hypereosinophilia developed in a minority of patients, with a peak at week 12 (16.2% with BEC ≥ 1.5, and 1.7% ≥ 3.0) in cross-sectional analysis. BEC ≥ 1.5 developed in 28.9% and BEC ≥ 3.0 in 4.6% of cases with a minimal 1-year follow-up. Baseline BEC was significantly higher for patients developing BEC ≥ 1.5 and BEC ≥3.0, with an optimal cut-off point of 0.96 to predict developing BEC ≥ 3.0. CONCLUSIONS: Blood eosinophil count (BEC) ≥ 1.5 is transient and usually abates with no therapeutic interventions and BEC ≥ 3.0 is rare. Hypereosinophilic syndrome did not occur and switching to a different biological was rarely employed. A baseline BEC of ≥1.0 can be a reason for extra caution.

Risk of hepatitis B reactivation in patients with myeloproliferative neoplasms treated with ruxolitinib
Authors: Adesola Adeniyi Abraham , Cozma Matei-Alexandru , Chen Yong-Feng , Srichawla Bahadar Singh , Găman Mihnea-Alexandru
Published: November 2023

Classical Philadelphia-negative myeloproliferative neoplasms (MPNs), i.e. , polycythemia vera, essential thrombocythemia, and primary/secondary myelofibrosis, are clonal disorders of the hematopoietic stem cell in which an uncontrolled proliferation of terminally differentiated myeloid cells occurs. MPNs are characterized by mutations in driver genes, the JAK2V617F point mutation being the most commonly detected genetic alteration in these hematological malignancies. Thus, JAK inhibition has emerged as a potential therapeutic strategy in MPNs, with ruxolitinib being the first JAK inhibitor developed, approved, and prescribed in the management of these blood cancers. However, the use of ruxolitinib has been associated with a potential risk of infection, including opportunistic infections and reactivation of hepatitis B. Here, we briefly describe the association between ruxolitinib treatment in MPNs and hepatitis B reactivation.

The performance of non-invasive models in the diagnosis and prediction of liver fibrosis have not been evaluated in all populations. This study evaluated the accuracy of gamma-glutamyl transpeptidase-to-platelets ratio index (GPRI), and S-index in the diagnosis and prediction of liver fibrosis in patients with chronic hepatitis B virus infection (CHBV). Fifty patients with CHBV and 40 control were recruited into this case-control study. Albumin (ALB), alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, gamma-glutamyl transpeptidase (GGT) and platelet count (PLT) were determined by colorimetric methods and Sysmex XS-10000 haematology automated analyzer respectively. GPRI and S-index were computed. Data were analyzed using ANOVA, Pearson’s correlation and ROC curve at p<0.05. ALP, ALT, AST, GGT, GPRI and S-Index were higher (p<0.05), while ALB was lower (p<0.05) in patients with liver fibrosis (LF), compared to patients with CHBV. ALP, GGT, GPRI and S-index were higher (p<0.05), while ALB and PLT were lower (p<0.05) in patients with CHBV compared to the controls. ALP, ALT, AST, GGT, GPRI and S-index were higher (p<0.05), while ALB was lower (p=0.000) in patients with LF compared to the controls. The area under the curve (AUROC) for S-index and GPRI were (AUC=0.835, P=0.000), GPRI (AUC=0.778, P=0.003). This study shows that both S-index and GPRI are good test instruments for evaluating liver fibrosis in patients with chronic hepatitis B. S-index was a better marker than GPRI for predicting liver fibrosis.

Twenty-five  male Washera lambs with a mean body weight of 21.9±1.01 kg (mean ± SD) were used in randomized complete block  design consisted of five replications. The dietary treatments included: 0% CL+100% CM (T1), 25% CL+75% CM (T2), 50%  CL+50% CM (T3), 75% CL+25% CM (T4) and 100% CL+0% CM (T5). The data collected includes, chemical composition of  diets, nutrient intake, nutrient digestibility, carcass yield and quality. The microbiological quality assessment of the CL  indicated that it conformed to satisfactory limits of feed safety and therefore it fit for animal feeding. Sheep under T2  had higher (p<0.001) total dry matter intake (DMI) and organic matter intake (OMI) whereas as compared to other  treatment groups, sheep under T1 and T5 had lower (p<.001) total DMI and OMI, respectively. The DM digestibility  coefficient was higher (p<0.01) for sheep fed with mixed supplement diet (T2 to T4). The protein digestibility coefficient  was higher (p<0.01) for the mixed supplement and lower for solely dried students’ cafeteria leftover (CL). Average daily  gain showed higher (p<0.01) for T1 but similar values for treatments (T2 to T4) compared to (T1 and T5). The average  empty body weight (EBW) and hot carcass weight (HCW) showed higher (p<0.01) for the dietary treatments (T2 to T4). According to the partial budget analysis, T4 was the most profitable diet, followed by T3, T2, T1, and T5. Based on this, it  is possible to conclude that CL could be included in Washera lambs CM rations at a level of 75% without any adverse  effect on the performance and carcass characteristics of sheep. Drying and processing of the entire student cafeteria  leftover imposed due to sun drying of laxative food leftover such as pasta. As food leftover contains more moisture and  is easily spoiled, guidelines for collecting, transporting, drying, and storing raw materials should be developed to ensure  the safety of food leftover for animal feed. Thus, further research is required to investigate technological options  for properly drying laxative food leftovers such as pasta so that such food leftovers can be used for ruminant  animal feed.

The objective of this study was to assess the concentrations of selected heavy metals at Kuru Dam. The result obtained shows that Fe ranged from 0.05- 0.55ppm, As 0.13-0.18ppm, Cu 0.06-0.36ppm, Pb 0.08 -0.46, Cd 0.01-0.02ppm, while Zn 0.01-0.01ppm. The results were compared with, FAO and NESREA standards. The data revealed that Fe, Zn, Cu and Cd concentration levels were found to be less than permissible limit concentration levels of while Cd, Pb, and As in water samples were beyond acceptable limit. Excess Cd could lead to kidney damage, respiratory problems, increased risk of lung cancer, and bone diseases; high concentration of Lead could cause cognitive impairments, learning disabilities, developmental issues in children, while overexposure to Arsenic may cause skin lesions, cardiovascular diseases, lung cancer, bladder cancer, and induce developmental abnormalities in children, accordingly. More so, excess levels of cadmium, lead, and arsenic have extensive implications for human health, environmental sustainability, and socio-economic aspects in the study area.

Agricultural technology development is an essential strategy for increasing productivity among farmers. This study evaluates the effect of adoption of improved farm technologies on output among staple crop farmers of Nigeria agricultural transformation agenda. Multistage sampling technique was used to select 220 farmers each of Staple Crop Producing Zone (SCPZ). Primary data were collected with the aid of structured questionnaires. The data collected were analyzed using descriptive statistics, likert scale rating and z-statistic. The results showed an average age of 47 years for cassava, 44 years for sorghum and 44 years for rice farmers. The is higher adoption rate observed among the farmers with weighted mean score greater than 3.00 cut off.. The average farm size put into cassava, sorghum and rice production were 1.91, 1.66 and 2.1 respectively. The average yield of cassava before ATASP-1 project was12, 096.11Kg/ha while the average yield after the project was double at 24, 292.23Kg/ha. Subjecting these yields to z-statistic test revealed that there was statistical significant difference between the yield before and after the project has taken off at 1% level of significance. Since there is positive impact of technology adoption impact on crop output of farmers who participated in ATASP-1 project it is therefore recommends that the volume of beneficiaries should be expanded so as to allow more people to benefit from the programme.

Coconut (Cocos nucifera L. (Arecaceae)) supplies nearly all of the basics of life, including food, oil and phyto-medicines. However, reports on the antioxidant effects of the stem bark of C. nucifera are scanty. Therefore, the objective of this study is to evaluate the antioxidant effects of coconut stem bark extracts using diphenyl-i-picrylhydrazyl (DPPH); hydrogen peroxide (H2O2) and nitric oxide (NO) scavenging assay using standard techniques The stem bark of the plant was pulverized and macerated with 70% ethanol. Antioxidant analysis was evaluated on the extract using diphenyl-I-picrylhydrazyl (DPPH), hydrogen peroxide (H2O2) and nitric oxide (NO) scavenging assay. Results indicated that the ethanol extract possesses dose-dependent antioxidant activity. DPPH scavenging activity assay showed an IC50 of 7.65 g/mL, hydrogen peroxide scavenging activity assay revealed an IC50 of 22.92 μg/mL and an IC50 of 79.83 μg/mL for the nitric oxide scavenging activity. In conclusion, the ability of the extract to scavenge for free radicals, demonstrates its ability to neutralize numerous radicals in different systems, suggesting that it might be helpful as a cheap source of phyto-antioxidant for the management of pathologies associated with free radicals' damaging effects.

Disease-causing microorganisms pose significant health challenges, and the search for alternative therapeutics remains a present quest.  Sida acuta Burm. f. is a common weed plant with reported pharmacological activities. The present study was to investigate the antimicrobial activities of chloroform extract of whole plant of S. acuta against selected clinical isolates from laboratory samples of a private hospital in Benin City, Edo State, Nigeria using agar well diffusion and broth dilution techniques. The bacterial isolates were properly identified, using standard morphological and biochemical techniques. Extract of whole plant of S. acuta was prepared by cold maceration in chloroform. The zone of inhibition diameter, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined to ascertain the antimicrobial activities of the plant extract. Morphological and biochemical observations were confirmatory for Staphylococcus aureus, Streptococcus sp., Escherichia coli, Pseudomonas aeruginosa, Klebsiella sp. and Proteus vulgaris. The highest (15.00 ± 0.29 mm) and lowest (5.50 ± 0.29 mm) zones of inhibition were recorded against P. aeruginosa and E. coli at 20 and 80 mg/mL respectively. However, no activity was recorded against C. albicans and A. niger. The extract had MIC of 62.5 mg/mL against S. aureus, Streptococcus sp. and Klebsiella sp. and MBC of 62.5 mg/mL against E. coli and P. vulgaris. The extract demonstrated broad-spectrum antibacterial activities against both Gram-positive and Gram-negative isolates.
