A Survey for High-redshift Gravitationally Lensed Quasars and Close Quasar Pairs. I. The Discoveries of an Intermediately Lensed Quasar and a Kiloparsec-scale Quasar Pair at z ∼ 5
Authors: Yue Minghao , Fan Xiaohui , Yang Jinyi , Wang Feige
Published: April 2023

We present the first results from a new survey for high-redshift (z ≳ 5) gravitationally lensed quasars and close quasar pairs. We carry out candidate selection based on the colors and shapes of objects in public imaging surveys, then conduct follow-up observations to confirm the nature of high-priority candidates. In this paper, we report the discoveries of J0025–0145 (z = 5.07), which we identify as an intermediately lensed quasar, and J2329–0522 (z = 4.85), which is a kiloparsec-scale close quasar pair. The Hubble Space Telescope (HST) image of J0025–0145 shows a foreground lensing galaxy located 0.″6 away from the quasar. However, J0025–0145 does not exhibit multiple lensed images of the quasar, and we identify J0025–0145 as an intermediate lensing system (a lensing system that is not multiply imaged but has a significant magnification). The spectrum of J0025–0145 implies an extreme Eddington ratio if the quasar luminosity is intrinsic, which could be explained by a large lensing magnification. The HST image of J0025–0145 also indicates a tentative detection of the quasar host galaxy in the rest-frame UV, illustrating the power of lensing magnification and distortion in studies of high-redshift quasar host galaxies. Object J2329–0522 consists of two resolved components with significantly different spectral properties and a lack of lensing galaxy detection under subarcsecond seeing. We identify it as a close quasar pair, which is the highest confirmed kiloparsec-scale quasar pair to date. We also report four lensed quasars and quasar pairs at 2 < z < 4 and discuss possible improvements to our survey strategy.

Low back pain, categorized as nociceptive, neuropathic, or nociplastic, is the leading cause of disability in terms of years lived among young people. The lumbar spine may produce specific or non-specific pain. Treatment depends on the underlying cause of low back pain. This review discusses the classification, prevalence, diagnosis, and treatment of low back pain in young adults.
Non-invasive Evaluation of Liver Fibrosis
Authors: Heo Nae-Yun
Published: April 2023

An evaluation of liver fibrosis severity during the initial examination is essential for the determination of chronic liver disease prognosis. Although liver biopsy is the gold standard for evaluation of liver fibrosis, bleeding can occur. Therefore, several non-invasive approaches have been introduced, including an equation with clinical variables and assessments of liver stiffness (e.g., elastography). Most patients with chronic liver disease can undergo evaluation of liver fibrosis severity without a liver biopsy using these alternative methods.
Le lieu du quotidien au Japon
Authors: Bonnin Philippe
Published: April 2023

Notre propre « détour ethnographique » par le Japon nous permet de nous interroger sur ce que l’observation des pratiques quotidiennes d’un autre peuple, si éloigné soit-il, peut nous apprendre des nôtres. Ce quotidien de vie révèle, au-delà de l’apparence, des formes sociales et culturelles plus profondes, quand elles se disent à la fois en langue vernaculaire et dans celle de l’espace.
« À pas comptés ». Invention de la science ménagère et emploi du temps, de la fin du XIX e siècle aux années 1950
Authors: Perrot Martyne
Published: April 2023

Si le mouvement de rationalisation domestique est déjà bien connu des spécialistes du travail, du genre et de la consommation dans la France du xx e  siècle, il s’agit ici de montrer comment le ménage fut présenté à la fin du xix e  siècle, d’abord en Amérique, ensuite en France, comme une science puis un art pour transformer le rythme de la vie quotidienne des femmes au foyer. En leur octroyant un nouveau statut d’experte, cet emploi du temps, minutieusement conçu pour alléger leurs tâches, les assignait aussi à résidence.

L’article propose une exploration des nuits de tous les jours. Il teste l’hypothèse contre-intuitive et paradoxale de l’existence d’un quotidien dans des nuits par nature extraordinaires, à partir des modes de vie de quelques figures particulières. Plus largement, il ouvre la réflexion sur la construction d’un quotidien hors de son œkoumène , comme condition même de l’habiter la nuit et effort constant dans un contretemps physiologique et social.
Année catastrophe, le moindre geste. Journal de bord
Authors: Laé Jean-François , Overney Laetitia
Published: April 2023

Nous retraçons quelques moments de l’année 2020, année catastrophe, au début de l’épidémie de Covid-19. Nous essayons de rendre compte de ce moment exceptionnel d’impuissance et de désarroi qui fait voir le quotidien. Comment voit-on, mais surtout comment se déplace-t-on dans l’espace pour voir ? Car il faut se bouger continûment pour saisir du quotidien. Le quotidien ne serait rien sans un journal tenu jour après jour, où se mêlent différents lieux observés, des successions de situations, des lieux d’expression comme les courriers et les messages d’appels au secours. L’article déploie une forme de sociologie narrative fondée sur les prises d’écriture d’étudiants en grande précarité et les situations de familles exilées confinées dans des hôtels en région parisienne.
L a temporalité du travail identitaire : renouvellement et maintien identitaire des organisations temporaires récurrentes
Authors: Havet-Laurent Stéphanie , Salaun Vincent
Published: April 2023

Cet article se propose de réfléchir au lien entre structure temporelle de l’organisation, plus particulièrement les organisations temporaires récurrentes, et temporalité du travail identitaire. La recherche propose une mise en dialogue de deux corpus, celui sur les organisations temporaires d’une part et celui sur le travail identitaire d’autre part. L’étude de deux festivals musicaux conduit à mettre en lumière le fait que le travail identitaire des organisations temporaires récurrentes se fait essentiellement entre les périodes d’activité et apporte donc un éclairage nouveau quant aux rôles et fonctions des états latents des organisations temporaires récurrentes. La complémentarité mise en évidence entre le processus de travail identitaire et le processus d’organisation de l’événement permet de suggérer une place centrale des états latents, bien au-delà d’une simple fonction de temps de construction d’un réseau de potentialités.

L’université : un terrain de lutte pour les agents de nettoyage en sous-traitance ?
Authors: Bret Hugo
Published: April 2023

Les différentes formes de violence éprouvées au sein des universités peuvent aussi s’exercer sur des groupes situés en marge des institutions et de leurs missions officielles. En dépit du caractère essentiel de leur activité, les agents de nettoyage externalisé·es sont invisibilisé·es des études sur les conditions de travail dans l’Enseignement supérieur et la recherche ainsi que sur leur lieu de travail. Elles et ils sont pourtant susceptibles d’être confronté·es à une dégradation de leurs conditions de travail qui résulte des logiques inhérentes au système de la sous-traitance. Le récit d’une mobilisation d’agents de nettoyage externalisé·es dans une université permet ainsi de rappeler les principales formes de violence subies qui en sont le moteur, et de préciser le rôle parfois déterminant des différents membres de l’université (syndicats, direction, personnel administratif et enseignant, étudiant·es) dans la genèse et l’issue du mouvement.
Le Fils unique et ses frères : une révélation johannique
Authors: de Lamarzelle Agnès
Published: April 2023

Le quatrième évangile construit progressivement le paradigme de la filiation divine des croyants en son lien avec celle du Fils unique. En étudiant la manière dont il le fait, on met en lumière le don inouï fait à ceux qui accueillent la révélation divine, introduits par le Fils devenu chair dans sa relation au Père. Quatre péricopes sont analysées, qui sont quatre étapes de ce chemin de révélation : le Prologue, la révélation à Nicodème, l’élévation du Fils de l’homme et la révélation à Marie de Magdala.
Actualité pastorale de la théologie lubacienne du surnaturel
Authors: Lemaire Marie-Gabrielle
Published: April 2023

Si le P. de Lubac a consacré de nombreux travaux à la théologie du surnaturel, c’est en raison de son importance cruciale dans l’annonce de la Bonne Nouvelle de Jésus-Christ. La théologie des deux ordres, naturel et surnaturel, par rapport à laquelle se positionne le P. de Lubac, a généré une approche pastorale que nous remettons en question. En revanche et plus que jamais, l’anthropologie spirituelle qu’a promue le P. de Lubac semble répondre aux plus pressants besoins pastoraux de notre temps.
Recherche descriptive qualitative sur le niveau d’utilisation de l’environnement numérique de travail chez le cadre de santé de proximité en France
Authors: Martin Loïc
Published: April 2023

Si la société est confrontée à l’ère numérique, les professionnels de santé doivent aussi s’adapter à cette mutation dans un contexte d’ambition numérique en santé. La revue de la littérature sur les notions d’utilisation, d’usage, de pratique et d’appropriation du numérique apporte, en France et en comparaison à d’autre pays, peu de données sur les cadres de santé de proximité concernant leur pratique managériale. L’objectif de cette recherche est de mesurer le niveau d’utilisation et d’appropriation de l’environnement numérique de travail chez ces cadres, et d’identifier les dimensions influençant cette utilisation. Cette recherche descriptive qualitative est basée sur 30 entretiens semi-dirigés réalisés en France, en Normandie. Les résultats, issus d’une analyse catégorielle, démontrent une utilisation du numérique basique et un niveau d’appropriation correspondant à une phase d’application. Les principales dimensions qui impactent ce phénomène sont technologiques, stratégiques et liées à la politique de formation et d’accompagnement. Le cadre ne travaille pas dans un environnement numérique de travail. Il se trouve dans un processus d’instrumentation et serait plus dans un usage de l’environnement informatique de travail. Ce niveau d’utilisation ne dépend pas uniquement d’une analyse ontosystémique du cadre. Une réflexion écosystémique serait à privilégier, centrée sur les stratégies du déploiement rapide d’une culture numérique contemporaine.

De l’allaitement parental à un trois-étoiles Michelin !
Authors: Renaud-Goud Mathilde , Sztark Véronique , Maret Aniki
Published: April 2023

Le repas du tout-petit est vital, tant sur le plan physiologique que relationnel. Lové dans les bras de son parent, yeux dans les yeux, le bébé boit. En collectivité les institutions doivent travailler précisément les conditions dans lesquelles le repas sera offert aux petits enfants, afin de soutenir leur capacité à se nourrir. Individualiser le plus possible ces moments-là permet à l’enfant de manger tranquillement, et aux adultes de s’ajuster à ce dernier et de prendre plaisir à être avec lui. Cela implique également de réfléchir à l’activité des enfants pendant le repas des autres, afin que l’alternance entre moment de rencontre avec l’adulte et moment de jeu avec soi-même soit source de créativité.
Pourquoi tant de conflits autour du repas ?
Authors: Rasse Miriam
Published: April 2023

Au cours des repas se construit une relation entre l’enfant et l’adulte qui le nourrit, au sein de laquelle le bébé apprend à se connaître et exprime son état de dépendance comme ses désirs d’autonomie. Ces manifestations du bébé viennent rencontrer la responsabilité de l’adulte, et les inquiétudes qui s’y attachent, d’assurer la survie de l’enfant, son alimentation saine et équilibrée. Cette rencontre peut être source de conflits qui, bien qu’ayant une valeur structurante, peuvent trouver une issue plus paisible lorsqu’un dialogue peut s’instaurer entre eux, contenue par un cadre rassurant pour chacun.

Influence of a New Media Data Interaction System on the Course Teaching Effect
Authors: Ke Wenjuan , Ji Zijun
Published: April 2023

The new media data interaction system is the product of the joint development of information technology, computer technology, and education reform, which has a certain impact on the traditional teaching model. To continuously improve the course teaching effect, the influence of the new system on the course teaching effect was investigated. Experimental and control classes were set and the number of each class and teaching time were confirmed. The experimental class adopted the new media data interaction system to assist the course teaching and made courseware of such a system through different methods, such as literature data, questionnaires, and experiment methods. Moreover, a pretest questionnaire and an in-class observation scale were designed and the experimental data were analyzed through t-test and statistical analysis. Results indicate there is no significant difference in student ability and academic performance between the experimental and control classes before participating in the study. After the participation, the mean scores of the in-class scale in the learning interest, learning attitude, and communication ability of the experimental class are 13.42, 13.26, and 16.37, respectively, which are significantly different from those of the conventional class (p<0.05). Thus, the new media data interaction system can improve the course teaching effect.

Authors: Liu Yifei
Published: April 2023

Video is an important carrier of all kinds of information on the Internet. More and more students choose to watch online learning videos from online learning platforms with various forms of intelligent terminals. To allow students to get the videos which they really need and are interested in from the mass videos, it is necessary to improve the existing personalized recommendation algorithm. Content-based recommendation method, collaborative filtering-based recommendation method and hybrid recommendation method often have the problems of loss of feature information or cocoon. To this end, this paper studies the personalized recommendation service of media educational resources based on multi-dimensional user features. This paper constructs a multi-feature candidate set based on student-video interaction, extracts and splices category feature, label feature and semantic feature of Internet media educational videos, and generates the representation of students’ learning preference feature. Based on the improved forward and backward recurrent neural network, this study constructs a recommendation model of Internet media educational videos oriented to students' preference points. The experimental result verifies the validity of the model.

Attaining Sustainable Development Goals Through Gender Equality in Information and Communication Technology (ICT)
Authors: Anchan Veerendra Manjunath , Manmohan Rahul
Published: April 2023

When ICTs are brought into an economy, society, or culture, their ability to positively influence development depends heavily on the existing infrastructure. This chapter demonstrates the importance of gender in understanding information systems (IS) in developing nations by drawing on the extensive literature on gender and development. The report examined how gender equality may help or hinder women's engagement in ICT to achieve the SDG target. It's vital for women's empowerment in the digital era that they have equal involvement in ICT, and this chapter aims to do just that. An Indian manufacturing company that has implemented an ICT strategy aimed at creating development and employment through software creation is also the subject of this chapter. Women have more options thanks to ICTs, as evidenced by a gendered viewpoint on software development. As a result, they also perpetuate the gender inequality that permeates society. Gender-based roles, norms, and practices in both the workplace and the home directly impact the success and sustainability of ICT-based development.

Published: April 2023

Objectives:

Call on people to treat the causes of physical diseases is to take into account the causes of psychological factors as well as external causes.

Materials and Methods:

The analysis was conducted by combining the classical medical books of Tibetan medicine, as well as the traditional culture and living habits of Tibetan people, with modern research results.

Results:

Many of the theories mentioned in Tibetan medicine related to mind-body medicine have been confirmed by modern research. Mental and physical treatment related to psychosomatic diseases should be administered simultaneously. First, when a person is healthy, he should cultivate his mind to build a solid psychological defense against diseases. Developing both the mind and body contributes to creating a stable physical protection barrier against diseases. When a person is ill, he should realign his mind and help his body adjust and promote its early recovery with the help of medications.

Conclusions:

Treating related psychosomatic diseases should treat the mind and body simultaneously. And the mind and body should be cultivated before diseases to reinforce the psychological and physical defense against diseases.

Authors: Zailani Ahmed Hauwa , Balogun Elizabeth Abidemi , Adebayo Joseph Oluwatope
Published: April 2023

Clerodendrum violaceum is an indigenous antimalarial remedy; its antimalarial efficacy has been previously authenticated. Haematological indices are usually affected in several disease conditions and can be affected by ingestion of drugs and medicinal plants. This study evaluates the effects of methanol leaf extract of Clerodendrum violaceum on haematological indices of mice. Six groups (A-F) of ten mice each were used. Groups B, C, D, E and F were administered 31.25, 62.5, 125, 250 and 500 mg/kg body weight methanol leaf extract of Clerodendrum violaceum respectively. Group A received 5% DMSO and served as control. After fourteen days of administration, five animals from each group were sacrificed and blood collected for analysis of haematological indices. Extract administration continued for another fourteen days after which the remaining animals were sacrificed and treated similarly. After 14 days of administration, there was a significant increase (p<0.05) in packed cell volume, haemoglobin concentration and red blood cell count, at all doses (except 500 mg/kg body weight) compared to control. However, extract administration significantly reduced (p<0.05) white blood cell count at 500 mg/kg body weight only; and significantly (p<0.05) increased lymphocytes at all doses compared to control. After twenty-eight days, there was no significant alteration (p>0.05) in all red blood cell indices except red blood cell count and haemoglobin which were significantly reduced (p<0.05) at 500 mg/kg body weight while mean corpuscular volume significantly increased (p<0.05) at the same dose. White blood cell indices were not altered significantly (p>0.05) except lymphocytes which significantly increased (p<0.05) at all doses compared to control. The methanol leaf extract of Clerodendrum violaceum increased red blood cells which may be beneficial in counteracting conditions that predispose to anaemia and hypoxia and increased lymphocytes which can strengthen immunity.

This study investigated the knowledge and perceptions of bioethics among biomedical researchers in Osun State, Nigeria using a semi-structured self-administered questionnaire during a capacity workshop in November 2020. Demographic data, and attendee’ awareness, knowledge, and perception on bioethics and need for ethical approvals for biomedical research were collated. Data was analyzed using descriptive statistics and expressed as frequencies and percentages. A total of 153 biomedical researchers comprising (58%) males, and (42%) females participated in this study. Majority of the participants (60.8%) hold academic positions and about one-third of the population were graduate students (30.1%). Awareness on bioethics was high (91.5%), and more common in schools (61.4%), with majority of the participants (77.1%) describing it as a field that addresses the social and legal issues arising from medicine and life sciences (p<0.05). However, there were considerable gaps in knowledge among participants in the students and academia category, with about 16% of participants considering none or only part of the principles while about 10% felt they could obtain ethical permits while research is ongoing or completed and only 13.7% affirmed that all biomedical related researches require ethical approval. This finding calls for the incorporation of bioethics module into the curriculum of graduate students. The use of online resources, short courses, workshops and seminars can also be explored for re-enforcing training even among non-school going researchers and professionals.

Published: April 2023

Natural and anthropogenic activities generally result to large production of heavy metals. These heavy metals produced are indiscriminately discharged into rivers and other water bodies. Wastewater treatment of industrial effluents become very necessary due to toxic effect of heavy metal pollutants and its indirect effect pose to human health. Banana peel, an agricultural waste biomass can be used to produce bio-sorbent for adsorption of heavy metals from industrial wastewater. This study focused on the production of chemically modified activated carbon using various concentrations of phosphoric acid for removal of lead and zinc metals from aqueous solution. Activated carbon was produced from waste banana peel through thermal pretreatment at temperature of 450℃ preceding chemical modification with different concentrations of phosphoric acid of 0.5 M, 1.0 M and 1.5 M. The three different concentrations of the phosphoric acids represent sample X, Y and Z respectively. To study the adsorption efficiency of chemically modified activated carbon using different concentrations of phosphoric acid, batch experiments were conducted on chemically modified samples to assess the adsorption of lead (II) and zinc metals from aqueous solution. The three adsorbents were interacted with varying parameters such as effect of initial concentration of lead and zinc metal of concentration of 10 mg/L and 2 mg/L respectively. Based on batch experiments conducted, results indicated that adsorbent dose, pH, initial concentration as well as contact time are important factors influencing lead (II) and Zinc metals adsorption from aqueous solutions. Percentage adsorption of lead (II) and zinc metals was above 80 % for all three chemically modified adsorbents investigated. The adsorption capacities of the adsorbents under study showed high adsorption capacity for both zinc and lead metals. This implies that sample X, Y and Z are good adsorbents for adsorption of both zinc and lead metals in an aqueous solution.
Impact of land use change on urban heat island in Etsoko West, Southern Nigeria
Authors: Kadiria Medina Omo , Fabolude Gift Oluwatodimu , Kurac Nura Umar
Published: April 2023

The phenomenon of urbanization and population growth is a major global concern, as both emerging and old cities continue to expand, particularly in developing countries. Nigeria's urban population has grown dramatically over the last five decades, resulting in shrinking green spaces and urban forest, as well as increased urban island heat. As a result, this study looked into the existing and predicted land use and land cover (LULC), as well as land surface temperature change in Etsako West LGA of Edo State, Nigeria. The supervised maximum likelihood classification method was used to classify the town into four classes using Landsat data from 1987, 2001, and 2020. Similarly, LULC for the year 2040 was predicted using the Markov and CA-markov models. The Landsat Project manual was used to extract the land surface temperature. It was discovered that the built-up area increased over time, from 28.1 km2 in 2001 to 103.07 km2 in 2020, with a projected 166.93 km2 in 2040. Furthermore, forestland decreased throughout time, but the decline was more pronounced in 2020, with decline of twice that of 2001. Cultivated/grassland land has increased over time and is expected to continue to do so in 2040, but surface water hasn't changed significantly. The average land surface temperature climbed from 25.67 °C in 1987 to 32.39 °C in 2020. The environmental impact of urban sprawl and rising urban heat cannot be overstated, as it includes both direct and indirect human and environmental consequences. As a result, eco-friendly strategies were recommended in ensuring sustainable urban growth and reducing urban island heat.
Seroprevalence and associated risk factors of Toxoplasma gondii infection in immuno-compromised women and sheep of Bahir Dar City, Ethiopia

Published: April 2023

Toxoplasmosis is one of the most significant worldwide zoonotic infections caused by the protozoan parasite Toxoplasma gondii. It is a major public health and veterinary concern in terms of mortality and morbidity. The objective of this study was to estimate the seroprevalence and assess the potential risk factors of T. gondii infection among pregnant women, HIV/AIDS patients, and sheep in Bahir Dar city, North West Ethiopia. A cross-sectional study design and systematic random sampling techniques were employed. Serum samples were analyzed for anti-T. gondii antibodies using a commercially available Toxo-latex agglutination test kit. Logistic regression analysis was employed to test associations between variables. The seroprevalences of T. gondii infection in the examined pregnant women, HIV/AIDS patients, and sheep were 70.8% (95% confidence interval (CI): 65.1-73.4%), 70% (95% CI: 63.3-76.8%), and 43% (95% CI: 38.5 - 47.4%) respectively. Multivariable logistic analysis showed that T. gondii infection was significantly associated with knowing the zoonotic nature of toxoplasmosis (adjusted Odds ratio [AOR] = 0.197, 95% confidence interval [CI]: 0.107 - 0.35), eating raw meat (AOR=3.27, 95% CI: 1.89-5.65), and owning a cat (AOR=9.35, 95% CI: 4.00-21.84) in pregnant women and HIV/ AIDS patients. Hence, comprehensive health education about toxoplasmosis, particularly for pregnant women and HIV/AIDS patients, avoiding consumption of uncooked meat, and cat contact for immune-compromised women are of paramount importance.

Rabies is a zoonotic viral disease that affects humans and animals and dogs are the primary source of infection. Information on domestic dog populations is vitally important for rabies control. The present study is to assess the demography of dogs, the incidence of dog bites, and the knowledge, attitude, and practice (KAP) of the communities concerning rabies in Bishoftu town. Cross-sectional household surveys were conducted from April to June 2021 involving a questionnaire survey and collection of retrospective patient records from healthcare facilities. A total of 244 respondents were interviewed using a structured questionnaire format to determine their KAP about rabies and dog ownership. Data on the incidence of dog bites and suspected cases of rabies from November 2019 to June 2021 were retrieved from the records of four health centers in Bishoftu town. In interviewed households (HH) 51.2 % owned at least one dog with a dog: human ratio of 1:9 and 1.54 dogs/household. In the participating households, 71% of dogs had been vaccinated against rabies. Almost all, 99% of the respondents had heard of rabies and identified the mode of transmission of rabies. However, 61.8%, had a moderate level of knowledge and 59.8% had an intermediate level of attitude, and 64.3% satisfactory level of appropriate rabies prevention practices score. There was a statistically significant association between knowledge score and age, occupation, and source of information as well as attitude score with age and source of information (p<0.05). Respondents who attend higher education were more likely to have higher practice scores in the prevention of rabies (p <0.05). There were significant correlations among the participant’s knowledge, attitude, and practice (p<0.01). A total of 612 victims were registered and received the post-exposure vaccine in Bishoftu over two years (2019 to 2021). We identified critical knowledge gaps related to factors influencing rabies prevention and control. The veterinary and public health sectors should play an important role in educating and raising community awareness. Moreover, the production and use of the banned nerve tissue vaccine in the public health sector in Ethiopia need attention.

In developing countries (DC), particularly in Cameroon, the demand for drinking water is increasing. To date, the methods of design, sizing and extension of existing drinking water networks are done through the EPANET application which is a simulation software based on the Hardy-Cross method. The main objective of this study is to set up a local tool adapted to the context of D.C. allowing the design, sizing and extension of networks based on the rough model method (RMM). Thus, on the basis of a previously modelled existing network, a comparison was made between the Hardy-Cross method and the RMM (according to the criteria: costs, speed of execution, aptitude for automation, fidelity and precision) with the multi-criteria analysis tool PROMETHEE II. The results of this analysis show that the best adapted method for the design, sizing and extension of drinking water networks is the RMM. It appears that the setting up of water supply networks in DC must be done by the RMM for affordable costs, rapid execution, easy reproducibility and reliable precision.

Cancer starts when cells in the body start to grow out of control (malignant growth). Colorectal cancer starts in the colon or the rectum. Annona Muricata is a medicinal plant and is considered as a basis for health preservation and care worldwide. Colorectal cancer has reached epidemic proportions and is considered as a serious health problem, therefore treatment and cure of this disease is of great clinical importance. 1,2 dimethylhydrazine (DMH) is a potent carcinogen for colon cancer in rats. In this study, rats were randomly allocated into six groups: control, extract alone, DMH, extract and DMH together, extract before DMH, DMH before extract. DMH was injected subcutaneously at 25mg/1000g body weight once a week for 16 weeks, while the ethanol extract of Annona muricata leaves (EEAML) were administered to rats orally at 120mg/1000g. After sacrifice, colon and liver sections were dissected out for histological and some biochemical analysis. Blood was also collected in EDTA bottles for hematological assays. The group injected with DMH (subcutaneously) and orally administered leaves extract of A. Muricata simultaneously showed similar results with the rats fed with normal feed, as there was absence of polyps in the rats’ colon when compared with those injected with DMH alone for 16 weeks. Malondialdehyde level of rats injected with DMH were significantly increased (p ˂ 0.05) compared to the control. Hematology indices and caspase 3 activity show the protective effects of EEAML against DMH.

In this study, we determined the capacity of metal organic framework, which we prepared by the solvothermal mixing of Zn ions and 1,4-benzenedicarboxylic acid (Zn/BDC) moieties to adsorb methyl orange (MO), and amoxicillin (AMX). Results obtained show that MO and AMX adsorption capacity by Zn/BDC (mg/g) was found to increase with increase in solution concentration, for each contaminant type. Three isotherm models were applied to the adsorption data: Freundlich, Langmuir, and Temkin.  R2 values obtained for the adsorption of MO, 0.9778, 0.8589 and 0.9038 for Freundlich, Langmuir and Temkin plots respectively, indicates that all three models fit the adsorption data appreciably good, with the Freundlich isotherm providing the best fit. Those for AMX, 0.6737, 0.0616, and 0.5300 indicated a poor fit, but the Freundlich isotherm came out as best fitting isotherm for AMX, an indication of a multilayer adsorption process. Maximum possible amount of contaminant adsorbed per gram of Zn/BDC deduced from the Langmuir isotherm for the adsorption of both contaminants were 93.46 mg/g and 18.41 mg/g for MO and AMX respectively. This, among other indicators, showed the preference of Zn/BDC for MO relative to AMX. Adsorption kinetic models: pseudo first order, pseudo second order, and Weber-Morris intraparticle diffusion models, gave R2 values that indicate that intraparticle diffusion dominated the adsorption of MO, while the adsorption of AMX followed pseudo second order kinetics, an indicator of chemisorptive mechanism. Calculated Qe values, were in close agreement with experimental values.

It has been generally established that the global food system needs to be transformed urgently, in order to meet the growing demand for food, feed and fodder. Agroforestry is a type of farming system that combines trees/shrubs with crops with the objective of enjoying a mutual benefit that enhances productivity, profitability and biodiversity, which at the moment is unpopular in Nigeria. Therefore the objective of this paper is to provide relevant information on the role of agroforestry in transforming the Nigerian food system. Some of the agroforestry technologies which can be used to achieve its mutual benefit include taungya system, home garden, alley cropping, improved fallow, woodlots, live fences, fodder banks, orchards or tree gardens, windbreaks, shelterbelts, trees on pasture and apiculture with trees. Planting trees as a component of crop farming is a smart way to achieve multiple purposes with a single enterprise. Planting multipurpose trees in a world affected by climate change can decelerate the negative impact of anthropogenic cause of climate change, while providing food for humanity. Hence, the paper also review the roles of agroforestry in the global fight against climate change, while also ensuring food security through food system transformation.

Published: April 2023

The global use of petroleum hydrocarbon for domestic and industrial purposes has necessitated the occurrence of the contamination of the living and non-living components of the environment. This study investigated the influence of water insoluble fractions of crude oil on physicochemical properties and microbes of soil obtained from a tertiary institution in Benin City, Nigeria using standard procedures. The result for soil physicochemical properties showed a significant increase (p ≤ 0.05) in total hydrocarbon, nitrate, phosphate and sodium ion, however nitrate ion decreased in day 28 and 42. Soil pH, electrical conductivity, calcium, potassium and magnesium ion concentration significantly decreased, although with very minute variations. Soil bacteria and fungi count also decreased significantly (p ≤ 0.05), with some variation in fungi count (p ≤ 0.05). The result suggest that treatment with water insoluble fraction of crude oil induced changes in the soil physicochemical and microbial component, which infers alterations in soil structure and component. This could negatively affect plant cultivation and growth, as well as animals and human that consume contaminated plants. Oil contamination should therefore be avoided or properly managed to prevent its detrimental effect on the non-ling and living soil component.
