Antioxidant Effects of Selenium Nanoparticles Prepared from Eruca Sativa Extract on Ketoconazole –Induced Testicular Oxidative Damage in Male Rats
Authors: Q. Shareef Basman , I. Al Qadhi Huda , A. Jamal Shayma'a
Published: April 2024

Background: Recent studies have shown that the anti-fertility effects of Ketoconazole can be minimized by taking an antioxidant nanoparticles based-plant extract in combination with the medication or by taking it after medication. One of the effective methods to improve its medicinal properties and decrease the toxicities of Selenium is by formulating it as nanoparticles. However, this is still a challenging strategy.
Objectives: The aim of this study was to analyze the impact of nano selenium, which was prepared from Eruca Sativa extract, on testicular oxidative stress parameters in rats that were treated with ketoconazole. The study will focus on the evaluation of glutathione peroxidase, superoxide dismutase, and malondialdehyde as indicators of oxidative stress.
Methods: In this study,  a 1% w/v solution of  plant extract was added to a solution of 10mM sodium selenite in different ratios, and placed on a magnetic stirrer in the dark for 12 hours at a temperature 50Cº and pH9. The solution was then left for 48 hours, and the optimal fabricated selenium nanoparticles were selected for further characterization. forty-eight rats were divided into six groups with eight animals in each. Group A was the negative control, while Group B was given oral Ketoconazole at a dose of 50mg/kg for fourteen days. Group BC, BD, BE1 and BE2 were given oral Ketoconazole at a dose of 50 mg/kg for fourteen days, followed by 200mg/kg Eruca Sativa, 0.5mg/kg oral sodium selenite, 0.25mg/kg oral nano selenium and 0.5mg/kg oral nano selenium for 28 days, respectively. Finally, the animals were euthanized and their testicle anti-oxidant parameters were evaluated.    
Results: Significant increases in glutathione peroxidase and superoxide dismutase ( p value < 0.001), and a decrease in malondialdehyde levels ( p value < 0.001)  were observed in groups treated with nanoparticles compared to control group.
Conclusion: Nano forms of prepared by Eruca sativa extract exhibit significant antioxidant effects on testicular tissues, while being available for several metabolic, biological, and physiological functions.

Authors: Sabea Aryaf M. , Al-Qaiym Majida A.
Published: April 2024

Background: The immune system and thyroid hormones have an inverse relationship, but both thyroid hormones and selenium play a crucial role in the immune system. However, when the levels of thyroid hormones decrease (known as hypothyroidism), their effect on immune system cells and their relationship with selenium supplements in the body are not well understood.
Objectives: The aim of this study was to investigate the impact of Se-nanoparticles on thyroid hormones and the blastogenic response of lymphocytes in various lymphoid tissues in rats with hypothyroidism.
Methods: A group of female Wister rats aged three to four months were randomly placed into five groups (each group has 6 rats) and were given  a basal diet on a daily basis. However, the daily water supply given to each group was different. The first group was the control group and received normal water, while the other four groups were given 0.02% methimazole in their drinking water every day for four weeks to induce hypothyroidism. Once the hypothyroidism was confirmed, the 3rd, 4th, and 5th experimental groups were given one of the following three treatments for four weeks, respectively: SC-SeNPs (0.1mg selenium per kg per day) as T1, Levothyroxine (0.9μg per 100g per day) as T2, or SC-SeNPs (0.1 mg selenium per kg per day) and Levothyroxine (0.9μg per 100g per day) as T3. In the end, blood samples were collected from euthanized animals using a high dose of anesthesia, and lymphoid tissue samples (spleen, Peyer’s patches and mesenteric lymph node) were preserved in 10% formalin.
Results: Our research has revealed that IgG, a humoral immunity marker, was found to be significantly decreased in hypothyroidism. However, when treated with  levothyroxine alone or in combination with Sc-SeNPs, the level of cellular immunity marker, IL-6, was found to be significantly increased in hypothyroidism when compared to the control group. Additionally, we observed histopathological changes in the lymphoid tissue of hypothyroidism rats, which included depletion of the white pulp of spleen with congestion in the blood vessels, a decrease in the lymphoid follicle of Peyer’s patches, and  a decrease in  the primary  and secondary follicles of the mesenteric lymph nodes .
Conclusion:  Thyroid hormones play a role in regulating innate and adaptive immunity. The combination of selenium with levothyroxine is  the most effective treatment for  hypothyroidism and improving the activity of the immune system cells .

Introduction: Chlorophenols (CPs) have become prevalent in the manufacture of herbicides, fungicides, pesticides, insecticides, pharmaceuticals, and dyes, contributing significantly to water pollution. Addressing this challenge, various treatment methods such as incineration, electrochemistry, photochemistry, biotechnology, and catalytic hydrodechlorination have been explored to reduce toxic chlorophenol contaminants. Hydrodechlorination stands out as an efficient technique for the removal of chlorine atoms. The dispersion of metal nanoparticles on supported materials significantly enhances the catalytic activity by increasing the specific surface area. Among these, carbon-supported nickel-cobalt-iron nanoparticles emerge as promising catalysts for the hydrodechlorination of 2-chlorophenol.

Method: This study employs a chemical reduction method at high temperatures under an inert gas atmosphere to synthesize carbon-supported ternary nickel-cobalt-iron nanocatalysts, aiming to detoxify soil and water from pesticide residues. The physicochemical properties of these nanocatalysts were characterized using energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Their catalytic activity was assessed through gas chromatography with a flame ionization detector (FID).

Results: The analysis revealed that metallic nanoparticles are uniformly dispersed on the carbon support, with particle sizes ranging from 10 to 60 nm and an average size of 30 nm. The hydrodechlorination (HDC) of 2-chlorophenol (2-CP) achieved satisfactory conversions under various reaction conditions.

Conclusion: The carbon-supported nickel-cobalt-iron nanoparticles demonstrated effective catalytic activity for the hydrodechlorination of 2-chlorophenol, highlighting their potential for application in the treatment of chloroorganic contaminations in the future.

Introduction: Strain M1VB5, isolated from slime in paper machine pipes, is studied for its role in slime formation. This slime, comprised of microorganisms, binds and adheres to pipes, potentially leading to clogs, process inefficiencies, and machinery contamination.

Methods: We investigated the biological characteristics and gene sequencing of M1VB5, focusing on its biofilm biosynthesis capabilities under varying sucrose concentrations, temperatures, pH levels, and time periods.

Results: M1VB5 exhibited adaptability across a broad range of conditions, thriving at temperatures between 15-55°C and pH levels from 5 to 9, with up to 7% salinity tolerance. Capable of utilizing diverse carbon sources, M1VB5 efficiently biosynthesized extracellular enzymes, including CMCase, cellulase, xylanase, amylase, protease, and chitinase. Identified as Priestia megaterium (Gram-positive), it demonstrated significant biofilm formation, producing 36.4 g/L EPS and forming a 53.73 g/100g biofilm on PVC at a sucrose concentration of 100 g/L. Optimal biofilm production was observed at pH 8, with 28.40 g/L EPS and a biofilm mass of 59.61 g/100g PVC, and at 37°C, where EPS and biofilm weights reached 23.60 g/L and 63.78 g/100g PVC, respectively. The strain maintained steady biofilm production from day 4 to 14.

Conclusion: M1VB5's versatile carbon source usage, wide temperature and pH range tolerance, and diverse enzyme production facilitate its growth and development. Its significant biofilm and EPS production capabilities contribute to its dominance in slime formations, offering insights for managing slime in industrial paper mill environments.

Mammalian cells infected with Helicobacter pylori show an accumulation of DNA double-strand breaks (DSBs). Previous studies have shown that the virulence factor CagA of H. pylori induces genomic instability in host cells. Most DSBs in infected cells are repaired by nonhomologous end-joining (NHEJ) pathways. Indeed, impairment of NHEJ-mediated DSB repair may lead to genetic alterations and contribute to the development of gastric cancer. Nonetheless, the impacts of H. pylori and its virulence factor, CagA, on the efficacy of NHEJ are poorly defined. This study aimed to reveal the effect of GD13, a CagA-H. pylori strain isolated in Vietnam, on the NHEJ-mediated repair of DSBs in host cells. For this purpose, we utilized GCV6 cells with an NHEJ-reporter substrate, which has been proven to be an appropriate model for evaluating the repair efficiency of NHEJ in H. pylori-infected cells. The level of interleukin-8 released into the cell culture supernatant was measured by ELISA. Our findings suggest that the reference CagA+ 26695 strain impaired the NHEJ-mediated repair of double-strand breaks (DSBs), whereas the GD13 strain has not exhibited any discernible effect thus far. In addition, H. pylori strain GD13 triggered a lower level of interleukin-8 secretion in GCV6 cells than did the CagA-positive strain 26695.

Published: April 2024

Environmental sustainability is one of the key factors for socio-economic preservation and development. This depends a lot on consumer behavior in modern society. The main purpose of the research is to explore the factors that influence the consumption behavior of environmentally friendly products among young people. This study has expanded the Theory of Planned Behavior (TPB) by two antecedent factors determining consumer attitudes toward environmentally friendly products: green perceived value and environmental knowledge. Empirical research was conducted on young people (gen Z) to gain a better understanding of their green consumption behavioral intentions. Qualitative research methods have proposed theoretical models, corrected scales and quantitative research have provided to test measurement models and theoretical models. The findings show that the green perceived value scale is a multidimensional scale and the scales in the research model are confirmed to be valid and have high measurement reliability. Besides, testing the research model using Structural Equation Modeling (SEM) also confirmed that the two expanded factors of the TPB model (green perceived value and environmental knowledge) have a positive impact on green consumption attitude and green consumption attitude is also the factor that has the strongest impact on young people's green consumption intention. In addition, the factors subjective norm and perceived behavioral control are also confirmed to have a positive impact on green consumption intention.

Il cancro dello stomaco sta guadagnando importanza in Brasile, a causa dell’aumento quantitativo della patologia nella popolazione. I principali fattori di rischio evidenziati da studi epidemiologici sono i fattori genetici e ambientali, principalmente l’alimentazione caratteristica del paese, ricca di alimenti ad alto contenuto di sodio e amido, oltre al consumo di bevande alcoliche e il fumo, nonché l’infezione causata dal batterio Helicobacter pylori, che è correlata a processi patologici dello stomaco che possono portare allo sviluppo di cancro gastrico. Pertanto, lo studio ha concluso che la regione nord del Brasile è la più colpita da questo tipo di cancro rispetto alle altre regioni del paese, a causa della predominanza dei fattori di rischio in questa località e degli alti tassi di cancro dello stomaco registrati durante il periodo analizzato dallo studio.

“In payment for its services” in 1823-1856: Domestic service in Chile through wills
This article studies domestic service in Chile, particularly in the province of Concepción, during the first half of the nineteenth century. The main objective is to characterize the social and labour dynamics involved in domestic service during the first years of the Republic focusing on the study of the testamentary practices of the local elite evidenced through the review and analysis of wills notarized in the city of Concepción between 1823 and 1856. Methodologically, the selection of wills was carried out in a universe of 315 wills, 73 of which contained bequests to domestic service, and their analysis was carried out both quantitatively and qualitatively. The main conclusions are related to the characterization of the objects bequeathed and to the materialization or agency in the delivery of the bequests. 
Resumen

Political elites, agency discretion and anti-corruption governance in Chile
Authors: Schorr Bettina , Carrasco Sebastián , Moya Emilio
Published: April 2024

Between 2015 and 2018, Chile experienced several political corruption scandals that implicated the country’s political elite across the party spectrum. However, the outcomes of the ensuing judicial investigations have faced wide-spread criticism for being unsatisfactory, failing to set legal precedence, and weakening Chile’s anti-corruption governance. This article addresses the gap between Chile’s strong structural and formal conditions and the limited legal consequences faced by politicians involved in corruption. It examines the factors that allowed most politicians and their allies to avoid significant legal penalties. Drawing on different literatures related to professional politicians and political elites, institutional weakness, and agency discretion, the article analyses four prominent political corruption cases. We argue that favourable appointments of sympathetic executives allowed the Chilean political elite to exert control over the discretionary powers of state agencies involved in the legal processes. The article relies on a press review, secondary literature, and expert interviews.
Resumen: Elites políticas, discrecionalidad de agencias y gobernanza anticorrupción en Chile 
Entre 2015 y 2018, Chile experimentó varios escándalos de corrupción política que implicaron a la élite política de todos los partidos. Sin embargo, los resultados de las investigaciones judiciales subsiguientes han sido objeto de críticas generalizadas por ser insatisfactorios, no sentar precedentes legales y debilitar la gobernanza anticorrupción de Chile. Este artículo aborda la brecha entre las sólidas condiciones estructurales y formales de Chile y las limitadas consecuencias legales a las que se enfrentan los políticos implicados en casos de corrupción. Examina los factores que permitieron a la mayoría de los políticos y sus aliados evitar sanciones legales significativas. Basándose en diferentes literaturas relacionadas con los políticos profe-sionales y las élites políticas, la debilidad institucional y la discrecionalidad de la agencia, el artículo analiza cuatro destacados casos de corrupción política. Argumentamos que los nombramientos favorables de ejecutivos simpatizantes permitieron a la élite política chilena ejercer control sobre los poderes discrecionales de las agencias estatales involucradas en los procesos legales. El artículo se basa en una revisión de prensa, literatura secundaria y entrevistas a expertos.

This chapter conducts a comparative analysis of national park legislation, focusing on insights from the US National Park System to inform the development of China's emerging national park framework. Against the backdrop of a global conservation movement, the US system serves as a valuable model for China, which initiated its own national park system in 2017. On October 12, 2021, China has formally established its inaugural set of national parks, comprising the Three-River-Source National Park, the Giant Panda National Park, the Northeast China Tiger and Leopard National Park, the Hainan Tropical Forests National Park, and the Wuyishan National Park. Encompassing approximately 230,000 square kilometres, these five national parks safeguard nearly 30% of China's crucial terrestrial wildlife species. As China endeavours to enact comprehensive legislation for its national parks, this research aims to contribute to the ongoing efforts by addressing key questions such as the efficacy of the US's "One National Park, One Law" model, the governance dynamics between federal, state, and local entities, and strategies for balancing conservation with diverse land uses. The analysis spans five sections, exploring the historical evolution of the US National Park System, its legal framework, challenges faced by US national parks, and policy recommendations for China. The US experience highlights the importance of establishing clear legal authorities, fostering robust public participation mechanisms, and harmonizing relationships with Indigenous communities. The findings presented in this study aspire to facilitate a nuanced understanding of national park legislation, promoting international collaboration between the US and China for the sustainable management of natural lands and the protection of global biodiversity.
ВПЛИВ СТАТЕВО-РОЛЬОВОЇ ПОВЕДІНКИ НА СОЦІАЛЬНУ АДАПТАЦІЮ ДІТЕЙ-АУТИСТІВ
Authors: Харченко Н. , Перепелюк Т.
Published: April 2024

Стаття присвячена аналізу впливу статево-рольової поведінки на адаптацію та Я-концепцію підлітків з аутизмом. Розлад спектру аутизму (надалі «аутизм») характеризується труднощами соціальної взаємності, соціального спілкування, гнучкості та сенсорної обробки. Визначено поняття адаптації, статево-рольової поведінки, гендерної ідентифікації. Сьогодні актуальним є вивчення впливу психологічної статі на Я-концепцію, зокрема й дітей аутистів. Я-концепція в психологічній науці визначається як система уявлень людини про себе у зв'язку з її оцінкою. Таким чином, її структура включає три компоненти: когнітивний - уявлення про свою поведінку, здібності, зовнішність та соціальну значущість; емоційний - самооцінка, любов до себе; та оціночний - вольовий - прагнення підвищити самооцінку та здобути повагу. Крім того, поширеним залишається визначення Я-концепції як сукупності ставлень людини до самої себе. Доведено, що адаптація підлітків зумовлена статево-рольовою поведінкою і тим, як визначають себе дівчата та хлопці в контексті гендерної приналежності.

Recent progress in sequencing technology and the increasing number of chloroplast genomes available in liverworts have greatly improved our understanding of not only genome structure and evolution, but also its phylogeny and evolution. However, the plastome resource of this group is still ineffective, as the plastomes have been sequenced from a small number of species. In the present study, two newly sequenced chloroplast genomes from liverworts, one from Pallavicinia longispina Stephani and the other from Pleurozia subinflata (Austin) Austin were reported. The former genome has a length of 122,410 bp, with GC content 36.90%, and the latter has a length of 118,441 bp, with GC content 32.22%. A total of 132 and 127 genes were determined in the plastomes of P. longispina and P. subinflata, respectively. Furthermore, 41 short sequence repeats (SSRs), 419 editing sites and 15 non-adjacent repeats in the plastome of P. longispina, and 65 SSRs, 288 editing sites, and nine non-adjacent repeats in the plastome of P. subinflata were detected. Valuable genomic resources for further research on liverwort phylogeny, evolution, and population genetics are provided from this study.

Authors: Nahid Meher , Bhuiyan Mohammad Nazrul Islam
Published: April 2024

Essential oils (EOs) are among the most important plant secondary metabolites. Zingiber purpureum Roxb. is a tropical ginger from Bangladesh, but its chemical constituents of leaves and rhizomes, both EOs, may have pharmacological effects. The aim of this study was carried out to analyze the qualitative composition of both Essential oils (EOs) of both leaf and rhizomes of Z. purpureum. The EOs from the leaves and rhizomes were extracted by hydrodistillation. Chemical constituents of the EOs were separated and identified by gas chromatography/mass spectrometry (GC/MS), and the relative percentage of each constituent was determined by area normalization. In total, 81 compounds were identified from leaf EOs, whereas 44 were from rhizome EOs. The common compounds identified from both rhizome and leaf EOs were triquinacene, 1,4, bis (methoxy), b-phellandrene and b-sesquiphellandrene, respectively. Besides, the major constituents of leaf EOs were sabinine (14.99%), b-pinene (14.32%), caryophyllene oxide (13.85%), and caryophyllene (9.47%), whereas the rhizome EOs confirmed (Z)-ocimene (21.97%), 4-terpineol (18.45%), γ-terpinene (3.86%) and cis-sabinenehydrate (3%). These EOs could be a promising source for the development of nutraceuticals, functional foods, and pharmaceutical products due to their potent activities and exploitation.

Morphometric features are efficiently used for the differentiation of species and long-term management of fish populations. Truss analysis is a frequently used taxonomic method as well as a stock identification tool to dissimilitude the morphologically similar species. Using landmark-based truss networking techniques following 18 morphometric lengths, 10 meristic counts, and 23 truss-network distance, the morphological variation of three croaker species viz. Johnius borneensis, Johnius argentatus, and Johnius belangerii were examined from Bangladesh coast. Data were analyzed and visualized through univariate ANOVA, canonical discriminate function analysis (DFA), and principal component analysis (PCA). Results found that the first DFA was responsible for 80.6% & 81.1%, whereas the second DFA was responsible for 19.4% & 18.9% variations among three species for the morphometric and truss-distances, respectively. In addition, 14 out of 18 morphometric and 12 out of 23 truss-network measurements were significantly different (p < 0.05) among means of three species. 1st PCA found 70.76% & 64.49% explained variations and 2nd PCA displayed 12.8% & 11.5% explained variations respectively for morphometric and truss distances. The findings of the study demonstrates that J. borneensis and J. belangerii are highly morphologically similar and J. argentatus is completely distinct which might be due to their physiological and genetic variations. The present study might be helpful in differentiating species and managing existing stocks of marine fish. Further studies regarding the molecular characterization of the Cytochrome c oxidase subunit I (COI) gene could confirm the genetic variations among these species.
