Technologies and innovation in secondary schools: rethinking teaching to improve student satisfaction
Authors: Storai Francesca , Rossi Francesca , Mori Sara , Toci Valentina
Published: January 2023

The use of new technologies is one of the themes at the centre of the educational debate, especially following Distance Education. The Avant-garde Educative Movement gathers schools from all over the country that share experiments based on a model in which the student is at the centre of his or her own educational path, a model capable of promoting meaningful learning. The Self Determination Theory (Deci & Ryan, 1985) highlights the extent to which the satisfaction of the needs for autonomy, competence and relationships contributes to student motivation. The purpose of the present study is to understand whether the rethinking of teaching promoted by widespread use of new technologies has had an impact in terms of student satisfaction. For the analysis, a Multilevel Model was used that assumes as the dependent variable students’ satisfaction with their school life from the Clipper Test, a-Portfolio for the orientation of students aged 15–19 (Soresi & Nota, 2003). The scale captures satisfaction with the school experience in terms of preparation received, relationships established and congruence with expectations. Results show that satisfaction increases as the use and frequency of innovative teaching methodologies employed by the teacher increases and as the frequency of use of technological resources employed in the classroom and in homework assignments increases.

Learning in the post-digital era. Transforming education through the Maker approach
Authors: Gratani Francesca , Giannandrea Lorella , Rossi Pier Giuseppe
Published: January 2023

In today’s world, technology and digital media are no longer separate, “other” than “natural” human and social life. Technology has become pervasive, transparent, reaching a “stable” form, no longer revolutionary. A new concept, “the post-digital,” is emerging and gradually taking hold in a wide range of fields. The resulting complexities call for overcoming the binary and hierarchical approach between theory and practice by rethinking traditional teaching patterns and remediating knowledge. Maker Education is moving in this direction. It is considered a technology-based extension of activism, developing STEAM and 21st-century skills. Its main exponents believe that it can “disrupt” or transform traditional educational methods. The Maker Movement, indeed, overlaps with the natural inclinations of children and the power of learning by doing. This contribution presents an ongoing research project that aims to outline a proposal for integrating this approach into the primary and lower secondary school curriculum. We detected its impact on students’ school self-efficacy and attitude toward STEM and 21st-century skills. The results collected in the first part of the project look promising. The data underline the pupils’ interest in STEM subjects and the improvement of their organizational and interpersonal skills.

Objetivo: Analisar as principais complicações da endometriose, principalmente as relacionadas à fertilidade, e de que maneira minimizá-las. Revisão Bibliográfica: A endometriose é uma doença ginecológica crônica, com etiopatogenia pouco elucidada e complexa, caracterizada pela presença de estroma e de glândulas endometriais fora da cavidade uterina, sendo estrogênio dependente. Infertilidade acomete 30-50% das mulheres em idade reprodutiva portadoras de endometriose, pois esse quadro gera inflamação das estruturas pélvicas de forma significativa e provoca lesões nos tecidos envolvidos. A endometriose pode ocasionar ainda alterações hormonais no ambiente endometrial - prejudicando a implantação do ovo, anormalidades anatômicas pélvicas e dispareunia. Há diferentes tratamentos a serem utilizados a depender da gravidade e individualidade do caso, sendo esses: medicamentosos hormonais, cujas funções variam entre estímulo da ovulação e diminuição das lesões; cirúrgicos, como a laparoscopia ou a laparotomia; e de técnicas de reprodução assistida, como a Inseminação Intrauterina e a Fertilização in Vitro. Considerações finais: A endometriose é uma causa importante de infertilidade em mulheres em idade reprodutiva e pode se tornar uma doença grave se não tratada precocemente. Por outro lado, há alternativas para tratamento e sucesso em tentativas de gestação para estas pacientes.

An Analysis between Foreign Direct Investment and Intra-Industry Trade in Turkey: A VECM Approach
Authors: ŞENTÜRK Canan
Published: January 2023

The stylized world of identical technologies between countries, perfect competition and homogeneous products in the markets, and inactivity of production factors/inputs between countries is no longer valid. Knowledge economy, imperfect competition, differentiation, industrial clusters, new economic geography, transportation and transaction costs are among the factors that create the transformation in international trade. However, there is a specific literature that highlights the existence of examples of firms that are competitors or interconnected as parts of a single supply chain in the international economy, and spread of production activities to the world geography as an extension of the global transformation in production processes. In this context, since multinational firms mostly produce differentiated goods and a large part of intra-industry trade (IIT) is based on intra-firm trade of these firms, the linkage between foreign direct investment (FDI) and IIT is important. This connection is also supported by the fact that FDI is among the country-specific determinants of IIT in the literature. For this purpose, in this study, IIT index values for the period 1995-2020 in Turkey are calculated based on the distribution of exports and imports according to BEC classification. And FDI values related to industrial sectors in the same period are taken as basis. The relationship between the series is examined by cointegration analysis and the direction of the relationship is revealed by causality analysis based on vector error correction model (VECM). In the results of the study, it has been determined a one-way causal relationship from FDI to IIT for capital goods; and from IIT (total) to FDI. This is consistent with the result of the existence of a significant and positive relationship between technology intensity and IIT thanks to FDI in the literature.
An Investigation into The Occupational Perceptions of Healthcare Professionals: The Covid-19 Pandemic
Authors: ERTOSUN Öznur
Published: January 2023

Psychological needs, uncomfortable when not met, are explained by our expectations of achievement, relationship, autonomy, and dominance. Since work life is an important determinant in meeting directly (or indirectly) the tangible and intangible needs of individuals, work-related experiences are very effective in individuals' occupational perceptions. Also, occupational preferences are based on reasons: conscious selection, environmental pressure, financial security, prestige and social benefit. In order to test this connection (and the sources of the differences), the pandemic period constitutes the justification for the sample design of the study, especially as it includes challenging working conditions for healthcare professionals. Accordingly, the main purpose of the study is to discuss the relationship between the occupational preferences of healthcare professions and their psychological needs, with the determinant of their specific working conditions. Mixed (pluralist) research method is used in the design of the study. While the perceptions of the respondents about the working conditions are determined through the socio-demographic information form and open-ended questions, the occupational preferences inventory and the new psychological needs assessment scale are used to evaluate the occupational perceptions of healthcare professions. The study sample consists of a total of 378 respondents selected from doctors, pharmacists, and nurses. The study points to important findings regarding the connection between the occupational preferences of health professionals and their psychological needs. In addition, occupational groups (doctor, pharmacist, nurse) differ from each other in terms of occupational preferences and working conditions.
FRONTEIRAS (TRANS) FORMADORAS: SUBJETIVIDADES NA LETRA DE COTA NÃO É ESMOLA

Published: January 2023

O presente trabalho tem por objetivo analisar a letra da música Cota Não É Esmola, de Bia Ferreira (2018), buscando apresentar como as fronteiras existentes para o acesso à Educação Formal atravessam a subjetividade de mulheres negras que podem, pelas suas resistências, produzir (trans)formações. A canção escolhida faz parte do Movimento Hip-Hop, ferramenta artística de construção e compartilhamento de conhecimentos produzidos no cotidiano de seus autores e, portanto, ferramenta que integra e estimula aspectos constitutivos da Educação Não-Formal. Estamos filiados à teoria foucaultiana do Discurso e também aos Estudos Feministas Negros. Utilizamos em nossas análises a materialidade linguística e a interseccionalidade presentes. Essa análise nos possibilitou apontar como as fronteiras se confundem e como em suas margens surgem manifestações únicas e impossíveis em outros espaços. Observamos, também, em Cota Não É Esmola, uma resistência questionadora dos Processos Educativos, apontamos as interdições pautadas na racialização dos sujeitos e as regularidades encontradas na subordinação interseccional estrutural: o dilema entre a sobrevivência e o acesso à Educação Formal desde o ensino básico até o superior e as (trans)formações subjetivas acarretadas pelo racismo nas mulheres negras e periféricas. Mesmo atravessadas pelos discursos racista, capitalista e patriarcal dominantes, atos transgressivos e subversivos podem alterar os efeitos de sentido desses discursos. Concluímos que Movimento Hip-Hop pode auxiliar os Processos Educativos da Educação Formal e, ainda, integrar a elaboração de Políticas Públicas de Inclusão e de Lazer das populações negras e periféricas jovens.

Published: January 2023

Este artigo apresenta os resultados de uma pesquisa narrativa, que abordou as práticas docentes voltadas ao atendimento das juventudes em um curso de formação profissional. A juventude é uma experiência psicossocial que perpassa os sujeitos jovens, trazendo a emergência de inúmeras vivências. No cenário educacional da atualidade, torna-se importante compreender como a escola e a educação compreendem as juventudes e como consideram seus conhecimentos e vivências na construção dos currículos e no desenvolvimento das estratégias de aprendizagem. Partindo da experiência docente junto aos jovens trabalhadores, esta pesquisa teve como objetivo descrever como os saberes e vivências trazidos pelos jovens, cotidianamente, ao curso de formação profissional alteram a prática docente, possibilitando novos aprendizados para professores e alunos. Este estudo ocorreu em uma unidade escolar, na cidade de São Paulo, que oferece o curso de formação de jovens aprendizes. Os sujeitos da pesquisa foram os professores que atuam no curso de formação, assim como os próprios jovens. Como instrumento de pesquisa, optou-se por cartas, as quais foram escritas por professores e alunos, relatando seu ponto de vista a respeito do processo educacional desenvolvido. Após o tratamento analítico do material coletado, foram criados dois eixos de discussão: uma sala e muitas juventudes; tribos fora do gueto. Quanto aos resultados desta investigação, as reflexões sobre estes eixos levaram à proposição de uma Pedagogia das Juventudes, a qual se constitui em uma proposta teórico-metodológica, embasada na ecologia de saberes, como uma prática educacional que atenda aos diferentes jovens nos mais diferentes contextos.

Introduction: End-of-life medical care (ELMC) plans and do-not-resuscitate (DNR) decision-making are usually affected by multiple factors compared to other medical care decisions. ELMC and DNR policy implementation are still diversified and heterogeneous, especially in Saudi Arabia, because policymakers have adopted no guidelines. Thus, this study investigated physicians’ knowledge, attitude, and practice regarding ELMC and DNR.

Methods: A cross-sectional study design was adopted. Three hundred physicians working at King Fahad Hospital of the University, Khobar, Saudi Arabia, were randomly selected and administered an anonymous self-administered questionnaire using the Likert scale. Data analysis was carried out using SPSS 23.0.

Results: Of 300 distributed questionnaires, 264 (88%) were completed and analysed. Knowledge gaps and negative attitudes were observed, a quarter of the participants were opposed to issuing a DNR order, and 29.0% considered DNR as equal to euthanasia as they practice. The participants’ patient age and religious factors were the most critical factors in the ELMC plan and DNR decision. The physician’s level of acceptance regarding a set of ELMC interventions and DNR decisions showed heterogenicity and uncertainty among participants.

Conclusions: The ELMC plan and DNR decision-making should be appropriately addressed in the medical residents’ training programs to bridge the knowledge gap and the physicians’ negative attitudes during their practice. Additionally, there is a need to update and unify the DNR policies at the national level, considering the patient’s right to be informed and involved actively during the decision process making. Finally, more prospective research is needed for the global standardization of ELMC.

The purpose of this work is to design a biodigester with high density polyethylene (HDPE) geomembrane material which will be effective in recycling biodegradable waste and produces both biogas and organic liquid fertilizer. A tubular trapezoidal biodigester is designed, following by the fabrication of a 300 litter’s prototype biodigester with a tarpaulin. After running air and water tightness of the system, quantified biodegradable waste are introduced with and observed for a period of 60 days. Several tests are then conducted on the biodigester to ensure that the system can support the load it will be subjected under normal functioning condition. These tests included shear test, peel test, and air tightness of the system. In order to predict the quantities of elements that can be produce by the biodigester, the nonlinear differential equations of the exchange inside the biodigester are written and solved by using the differential transformed method. Results obtained from the prototype and the HDPE geomembrane biodigester shows that, this design permits the recycle of biodegradable waste from any facility. The biogas obtained was proven to be rich in methane content and the organic liquid fertilizer was also rich in N-P-K fulfilling the basic requirement for plant healthy growth. The HDPE geomembrane biodigester could produce 1,250L of biogas daily at an approximate pressure 1.8 bars which can be approximated to 5 hours minimum bu4rning with a burner of 200L/h.

Samples cast with eggshell ash additive and quenched in water coolant had the highest hardness value of 82.4 at 25% wt. additive when compared with sawdust ash and groundnut shell ash additives. sand-casting enhances the hardness of the specimens and thus, can be used in many engineering applications such as engine blocks and wheels in automotive parts and aerospace components.
Comprehensive review on nano drug delivery systems bioanalysis
Authors: Onteru Sujeevan
Published: January 2023

Nanoparticulate drug delivery systems (NDDSs) offer a revolutionary strategy to fighting ailments. The NDDSs are uniquely and deliberately constructed as vessels for the transport of active pharmaceutical components (APIs), which leverages their distinct physicochemical traits, such as lengthened circulation period, enhanced targeting capability and evasion of drug resistance. Although the last three decades have seen considerable progress, our comprehension of how NDDSs' pharmacokinetics in vivo can affect their safety profiles is still insufficient. Examining NDDSs is way more complex than analyzing small molecules since their structure and composition are completely different, almost making regular analytical techniques inadequate for measuring correctly its behavior within living systems. The following advanced bioanalysis techniques are summarized to trace the in vivo fate of NDDSs: liquid chromatography tandem mass spectrometry (LC-MS/MS), enzyme-linked immunosorbent assay (ELISA), magnetic resonance imaging (MRI), radiolabeling, fluorescence spectroscopy, laser ablation inductively coupled plasma MS (LA-ICP–MS,) and size exclusion chromatography. These tools provide an invaluable way of examining a drug's journey through the body. By leveraging the most modern technologies, we are able to conduct a thorough survey of NDDSs and their various changes in structure, composition and form. This review can be beneficial for accurately assessing pharmacokinetics as well as gauging efficacy and safety profiles of new drug delivery systems. We hope this comprehensive overview will serve as an effective basis for application methodology when analyzing NDDSs.

Authors: Sara Chtioui  , Zineb Ait Si Ali  , Sana Rafi  , Ghizlane El Mghari  , Nawal El Ansari
Published: January 2023

We describe a case of a delayed diagnosis of Pendred syndrome. The patient had a history of total thyroidectomy 13 years ago .And presented when aged 30 with a cervical abscess of ectopic thyroid. The patient had a hearing loss from the early childhood and she had a 27 year old sister who present the same history of deafness and goiter. Pendred syndrome is an autosomal recessive disorder characterized by sensorineural hearing loss and thyroid dyshormonogenesis. It is caused by mutations in the PDS/SLC26A4 gene encoding for pendrin. Hypothyroidism in Pendred syndrome can be--although rarely--present from birth and therefore diagnosed by neonatal screening. We highlight to the general physician the classical features of this syndrome that would aid early diagnosis.

Published: January 2023

We study the forecast of the electrical energy demand of the N'Djamena city, Chad, by 2032 using the statistical model based on the linear regression technic. A series of data of the maximum power demand (PMA) for the past years from 2005 to 2017 are obtained from the dispatching center of the company national electricity board of N'Djamena, which allow us to make energy projection from 2018 to 2032. Then these data are analyzed by the statistical method of linear regression forecast. The results obtained by the linear regression are closed to that provided by the Excel trend curve and they have a strong linear correlation coefficient of 0.963 between the maximum powers estimated and the given years. In addition, the predicted power peak needed by electricity consumers by 2032 is 175 MW compared to 90 MW in 2017, meaning that in 15 years, the consumption of electrical energy will pass from simple to double.
Methylation status of potential genes in breast cancer patients and correlate them with gene expression
Authors: Naiyar Azmi  , Ayesha shahid
Published: January 2023

Breast cancer is one of the world’s most prevalent cancer among women. Globally approximately 2.3 million women are diagnosed with breast cancer in 2020. It arises due to epigenetic modification which outlooks aberrant methylation as its major cause. The methylation of DNA involves a covalent chemical modification which is one of the major drawback, promoting development of breast cancer. In addition, evidence and investigation suggest that these methylations at promoter region of CpG islands leads to silencing of gene associated with tumor suppressor which is involved in crucial gene expression leading to establishment of breast cancer. Among variety of hyper methylated gene involved in different function linked with breast cancer, the hyper methylation of BRCA1 gene is identified as the targeted gene in precipitating disorder. A lot of susceptible genes are identified and based on their penetrance ability are being classified In order to analyze DNA methylation status Bisulfite sequencing is employed which is based on the mechanism of converting every un-methylated cytosine into uracil. With the advancement in gene sequencing the concept of whole genome bisulfite sequencing is also on the way to determine the DNA methylation occurring at single base. Another robust and sensitive approach to determine the methylated status is RT-PCR, a diagnostic tool applied in order to detect the expression of single gene

Published: January 2023

The hydroponic farming industry is growing rapidly, and it can solve major world food crisis problems. Health monitoring and diseases identification of the plant is very important for agriculture. Monitoring of health and disease on plant plays an important role in successful cultivation of crops in the farm. Identification of the plant diseases is the key to preventing the losses in the yield and quantity of the agricultural product. It is very difficult to monitor the plant diseases manually. Some diseases spread so rapidly they can affect an entire plant and crop. Early detection of a diseases can prevent an entire crop from harm and attention a farmer would need to place on their system. The proposed system is capable of detecting the disease at the earlier stage as soon as it occurs on the leaf, hence saving the loss and reducing the dependency on the expert to a certain extent is possible. The aim of this study is to design, implement and evaluate an image processing-based software solution for automatic detection and classification of plant leaf diseases. This technology helps the farmer to identify what type of diseases that the plant is being affected. The image has been processed in MATLAB and the status of the leaf has been identified with the help of neural network classification. Then the environment circumstances such as temperature, humidity and moisture has been monitored. After the image has been processed in the software it sends SMS to the user by using Global System for Mobile Communication (GSM). The SMS contains leaf status, particular solution and environmental conditions.

Published: January 2023

The aquaculture industry is one of the fastest-growing sectors in the food industry. The Nile tilapia, Oreochromis niloticus, is an important and inexpensive species of fish. A study was conducted to determine the effects of divergent dietary crude proteins on fish growth performance and antibiotic susceptibility of bacterial pathogens infecting all-male tilapia (Oreochromis niloticus). Forty-eight fish samples were grouped into three groups based on crude protein percentages, including 15%, 30%, and 45%, and the fish's body weight and length were measured on days 15, 30, 45, and 60. Ordinary one-way ANOVA (Tukey's multiple comparison test) was applied to three divergent dietary crude protein groups for the examination of growth performance at different time points. Using the same fish samples, bacterial strains were isolated from fish skin and gills and identified based on their morphological characteristics and biochemical testing. Kirby Bauer's disc diffusion method was used to determine the antibiotic susceptibility of identified bacterial isolates. The ANOVA (Tukey's multiple comparison test) results showed that 45% crude protein level in fish feed led to a greater growth rate than 15% and 30% under high-performance conditions. The antibiotic susceptibility findings indicate that Staphylococcus aureus showed the highest sensitivity (50%) toward antibiotics while Pseudomonas aeruginosa showed the least susceptibility (10%). The study provides a new perspective on the impact of crude protein on fish growth performance, as well as baseline information for the management of fish diseases based on antibiotic sensitivity.

Adolescence is a phase of life characterized by major physical, emotional, social, and cultural changes. In this period, the puberty process stands out, and due to the action of several hormones, great changes are observed in body structure. For all these changes to occur, it is necessary for adolescents to consume nutrients in sufficient quantity and quality to meet the body's demands. One of the most important micronutrients at this stage of life is calcium, involved in several metabolic and structural processes, and which must be ingested daily through an adequate diet. This article discusses the role of calcium in adolescent growth and development, considering metabolic and clinical characteristics, highlighting the importance of this micronutrient for the current and future health of adolescents.

More than five United States administrations have employed unilateral and multilateral sanctions on North Korea; the same tool of coercion exerted on Iran, yet all efforts to record a successful nuclear deal with North Korea has proved abortive till date. This article seeks to address a key question: How do United States sanctions influence the behavior of North Korea towards nuclear disarmament? The aim is to analyze sanctions effectiveness with particular reference to the role of the United States in the denuclearization of the Korean peninsula. The theory adopted was political realism, which argues that power and coercion are major instruments for achieving state’s national interests. This article relied on secondary data which were analyzed through content analysis. The finding of the article suggests that United States sanctions have limited impact on the behavior of North Korea as the Supreme leader of North Korea continues with the aggressive behavior of six nuclear testing between 2006 to November, 2017. The key factor that undermines the effectiveness of the United States sanctions includes lack of credibility and relative menace in US use of coercion over North Korea, lack of airtight implementation of sanctions on North Korea, Plurality of objectives and the indoctrination of North Korea Juche Ideology. The study concludes that the United States ultimate goal of complete, verifiable and irreversible denuclearization (CVID) in Korean Peninsula is an inconsistent policy objective of various US administrations which conflicts with North Korea’s national interest. This article recommends setting up eagle-eyed monitoring committees to keep track on sanctions implementations protocols within United States ranks and member states of United Nations with the aim of tightening loopholes militating airtight execution of agreed sanctions.

Differentiated thyroid cancer is the first endocrine cancer but remains rare, representing only 1% of neoplastic pathologies. Its discovery at the occasion of distant metastasis is even rarer but not exceptional. We report the case of a 50-year-old woman with a papillary thyroid carcinoma in its vesicular variant revealed by renal metastasis at the anatomopathology of the nephrectomy specimen. The review of the literature shows that vesicular cancer is the most frequent in cases of revealed metastasis. Etiopathogenically, renal involvement occurs mainly via the hematogenous route, rarely via the lymphatic route. The treatment of metastatic CTD requires a multidisciplinary approach. In the presence of metastases revealing thyroid carcinoma, thyroidectomy is required, followed by lymph node dissection and isotopic treatment with iodine 131, which allows a white cervical map to be obtained with the direct destruction of iodine-binding metastases, followed by hormone therapy to slow down the thyroid axis. The treatment of metastases will depend on their location and characteristics. The prognosis of differentiated thyroid carcinoma is very favorable, but worsens when it is revealed by a distant metastasis. Survival is significantly better for patients with small volume and iodine-binding metastases.

Diarrhoea is a common problem among the elderly. “A study to assess the effectiveness of structure teaching programme on knowledge regarding diarrhoea in elderly among patient attendants in a selected hospital at Mangalore” has been carried by Ms. Moiranghem Soniya Devi in partial fulfilment of the requirements of the Masters of Science in Medical-Surgical Nursing at Srinivas Institute of Nursing Science, under Rajiv Gandhi University of Health Science, during 2016- 2018. Objectives of the study: The objectives of the study are to: assess the pre-test knowledge scores regarding diarrhoea in elderly patient attendants among at selected hospital, Mangalore, evaluate the effectiveness of structured teaching programme on knowledge regarding diarrhoea in elderly among patient attendants at selected hospital, Mangalore, To find the association between pre-test knowledge scores regarding of diarrhoea with selected socio demographic variables. Method: One group pre-test – post-test design was used. Imogene King’s Goal Attainment theory is used for preparing conceptual framework. The main study was conducted at selected hospital (Srinivas Institute of Health Sciences and Research Center) in Mukka. The sampling technique used was purposive sampling. Data collected by demographic proforma and structured knowledge questionnaire on knowledge regarding diarrhoea in elderly among patient attendants. Data collection was done from 18-3-2018 to 27-3-2018. Samples of the study consisted of 50 patient attenders in the respective hospital. Pre-test, and post-test were done.

Based on UNICEF data, overweight and obesity increased across all age and income groups. Overweight has a risk of developing hyperlipidemia and caused increase free radical and lead to oxidative stress. It’s result in cell damage and impacts on several diseases among others diabetes mellitus. Many Medicinal Plant have biochemical compound which is an important concern because of the potential to reduce free radicals. 0ne of them is ginger (Zingiber officinale Roscoe var Roscoe). Medicinal plant generally is usually used with various extraction method to obtain the required chemical content. Information of ginger for reduce free radical with maceration extraction method has been reported in previous studies but little information with decoction extraction method. This study aims to determine the reduction of free radicals with MDA (malondialdehyde) as a marker and increased antioxidant activity with SOD (superoxide dismutase) as a marker after administration of ginger. This research was used the true experimental with the randomized posttest only control group design. The groups of experimental were divided into three which G1: control normal G2: High Fat Diet (HFD), G3: HFD + Zingiber officinale Roscoe var Roscoe (ZO) 5 g/day. The period of study was 6 weeks. The level of liver MDA and SOD were investigated by spectrophotometer UV Vis. Based on ANAVA showed that HFD rat increase of body fat weight and MDA (p<0,05) and reduced of total antioxidant SOD (p<0.05). The conclusion of this research decoction of Zingiber officinale Roscoe var Roscoe could attenuate of lipid peroxidation induce by HFD.
