Keberadaan komik sering dipandang sebagai sebuah media hiburan dan ditujukan sebagai bacaan anak-anak yang bersifat fantasi, padahal komik dapat berperan sebagai media pembelajaran yang menyimpan sejarah. Kreatifitas komikus dalam
menyisipkan informasi dipandang sebagai salah satu merekam sebuah informasi baik bidang dalam sebuah kegiatan peristiwa, kejadian bersejarah dan banyak hal lainnya. Salah satu peristiwa yang terjadi saat ini adalah pandemic Covid 19, peristiwa ini dijadikan sebagai tema dalam proses pembelajaran Ilustrasi Aplikasi dimana para peserta diminta untuk merespon dan merefleksikan fenomena covid dalam sebuah komik. Visual yang dihasilan memiliki beragama pendekatan, sudut pandang dan refleksi, dimana narasi visual yang diungkap menjadi sebuah kisah yang personal dan memperlihatkan daya ungkap tersendiri. Faktor yang melatarbelakangi visual sangat beragam, faktor dimensi sosial, ekonomi, psikologi, kebudayaan dan agama. Analisa terhadap analisa visual berdasarkan faktor yang melatarbelakangi penting untuk diungkap, dimana keberadaan, pengalaman dan kesiapan peserta didik dalam mengahdapi pandemic covid 19 sangatlah beragam, dan tertuang dalam beragam refleksi pada komik.Metode dalam analisa karya dengan menggunakan pendekatan tinjauan seni rupa yang bersifat deskriptif, sekaligus memberikan identifikasi terhadap karakter rupa dan ragam visual yang ditemukan pada objek. Aspek visual, tata letak, warna dan elemen estetis akan dibahas dengan memberikan pendekatan budaya dan sosio-histori, gaya visual, komposisi, tata letak dan narasi yang dibangun pada komik tersebut. Hal ini menjadi menarik untuk dikaji, bahwa di bawah alam sadar para peserta didik memiliki bahasa ungkap tersendiri pada komik yang dihasilkan, baik dalam keadaan disadari atau tidak oleh perupanya.

Pada kondisi pandemic, banyak situasi dan perencanaan yang harus diadaptasi dengan beragam ketentuan dan regulasi, begitu pula dalam bidang penyelenggaraan pendidikan dan pembelajaran, dikeluarkan yang berupaya untuk meminimalisir pergerakan masif virus untuk menular kepada manusia dan membawa dampak kematian. Akibat pembatasan pergerakan aktivitas manusia/mobilisasi tersebut maka dampak yang terjadi pada aspek dunia pendidikan adalah tidak adanya rekomendasi
untuk melakukan pembelajaran dengan metode tatap muka yang bersifat berinteraksi secara langsung antara guru, dosen atau disebut fasilitator dengan murid atau siswanya. Hasil kuisioner dari aspek visual yang ditemukan pada karya mahasiwa, dimana mayoritas merasakan adanya penurunan kualitas pada perkuliahan online. Hal ini dirasakan akibat dari peserta yang tidak leluasa melakukan eksplorasi di luar ruangan karena kondisi pandemic. Begitupula terkait dengan keterbatasan eksplorasi objek apakah ada penurunan secara kualitas foto. Hasil karya foto yang dibuat kebanyakan tidak menggunakan teknik fotografi yang benar, komposisi yang tepat dan masih kurangnya pemahaman dalam mengatur pencahayaan (exposure), sehingga foto terlalu terang (over exposure) atau sebaliknya terlalu gelap (under exposure). Hal ini menjadi koreksi dan merupakan bagian dari evaluasi kedepannya untuk dapat diberikan pemahaman yang lebih mendalam hingga dapat dipahami oleh semua mahasiswa juga pihak penyelenggara pendidikan, khususnya Universitas Paramadina dalam situasi pandemic dan pembelajaran online.

Effect of cultivar and drying methods on phenolic compounds and antioxidant capacity in olive (Olea europaea L.) leaves
Authors: Filgueira-Garro Itxaso , González-Ferrero Carolina , Mendiola Diego , Marín-Arroyo María R.
Published: May 2022

Up to 5% of the total olive weight arriving at the mill is discarded as leaves. Interest in the possible uses of these residues is growing, because they constitute a potential cheap and abundant source of compounds with high total antioxidant capacity (TAC) associated with total phenolic content (TPC) and biophenols such as hydroxytyrosol (HC) and oleuropein (OC), which could be used as nutraceuticals or as natural substitutes for synthetic antioxidants. However, studies that characterize specific cultivars, interannual variability, and different drying methods are lacking. This work investigates the TAC, TPC, HC and OC in olive (Olea europaea L.) leaves under four drying methods (vacuum-drying, oven-drying, freeze-drying and air-drying). Leaves were collected from cultivars 'Arbequina' grown under organic methods and from 'Arroniz', 'Empeltre', 'Arbosana', 'Picual' and 'Arbequina' grown under conventional systems. Among fresh samples, 'Arbosana' leaves presented the highest TPC (34.0 ± 1.1 mg gallic acid equivalents/g dry weight (DW)) and TAC (146 ± 20 μmol Trolox equivalents/g DW) and the lowest interannual variability of the TPC (3.2%). The four tested drying methods were also compared as the effect on TPC, TAC, HC and OC. Freeze-drying and air-drying best preserved TPC and TAC in olive leaves. However, air-drying maintained greater OC (14–40 mg/g DW) than freeze-drying (3–20 mg/g DW). Air-dried ecological 'Arbequina' leaves exhibited the highest TPC and TAC. Consequently, this cultivar presented more valorization opportunities as a source of nutraceuticals or natural antioxidants.
Impact of the closure of a coal district on the environmental issue of long-term surface movements
Authors: Vervoort Andre
Published: May 2022

The environmental impact of deep underground coal mines using the longwall mining method is diverse, e.g., short- and long-term subsidence, damage to surface infrastructure, disturbance of the hydrogeological conditions, and the quality of groundwater and surface water. The study presented focusses on the long-term surface movements after the closure of an entire coal district. Due to the flooding of the underground infrastructure and rock mass, an upward surface movement or uplift is observed. For a specific site in the Campine coal district, Belgium results are presented of satellite data (radar-interferometry). However, the main aim of the study is to better understand the process of uplift and to determine the various mechanisms that are involved. For this purpose, an analytical framework was developed recently, and it was applied successfully in a relatively easy case. The case study of the paper is more challenging, but the usefulness of the analytical framework is clearly confirmed. The most important conclusions are that (i) the uplift is induced by an increase in water pressure after the closure, i.e., re-establishing the original hydraulic gradient, (ii) the expansion of both the goaf volumes and the volumes of the non-collapsed rock mass must be considered, and (iii) the assumption of a linear decrease of water pressure variation from the top to the bottom of the mined area at the end of the mining phase provides the most realistic results. However, the next step in the analysis should focus on a more advanced hydrogeological model of the complex underground environment.

Assessment of effects of ASR-induced cracking on direct shear strength of recycled concrete
Authors: Ziapour R. , Trottier C. , Zahedi A. , Sanchez L.F.M.
Published: May 2022

Recycled concrete aggregates (RCA) have been adopted as one of the most efficient methods to reduce the carbon footprint of the concrete industry. However, the performance of recycled concrete mixtures made of Alkali-silica reaction (ASR)-affected RCA is primarily unknown. In this work, two types of RCA were produced from ASR-affected concrete with distinct levels of deterioration (i.e., slight and severe). Three levels of secondary damage (i.e., expansion levels of 0.05%, 0.12%, and 0.20%) were selected and evaluated through the direct shear test. Results revealed that RCA concrete’s shear strength depends on the severity of the RCA’s past deterioration. Moreover, the performance of the concrete specimens subjected to direct shear are in accordance with the cracks features formed in the microstructure of the recycled concrete as a function of ASR-induced secondary expansion observed through the damage rating index (DRI).

Politiques du dénudement dans les luttes nationalistes et féministes en Égypte (1882-1956)
Authors: Bavard Florie
Published: May 2022

Du début du xxe siècle aux années 1950, en Égypte, le geste de se dénuder se politise. Cet article s’intéresse à la façon dont des militantes et artistes mobilisent le dénudement dans leurs répertoires d’actions et dans leurs stratégies rhétoriques à des fins nationalistes ou féministes. Cette recherche propose ainsi un panorama chrono-thématique des questions relatives à la corporalité féminine, mises au-devant de la scène par ces femmes engagées. Des années 1900 aux années 1920, l’étude se focalise sur les corps féminins dans la rue, visibles, mobilisés et révélés au nom du « bien-être de l’humanité ». Puis, pour évoquer le tournant des années 1920 et 1930, l’analyse porte sur les corps dans les sports ou à la plage, exposés et « bons » pour la nation. Enfin, la réflexion se déploie sur les « beaux » dénudements et la patrie dans les arts, la mode et les concours de beauté, du milieu des années 1930 aux années 1950.
« Qu’aurais-je trouvé de plus chouette à Paris, Lyon ou Marseille ? » Socio-démo-géographie des Français·es de Bruxelles
Authors: Casier Charlotte , Decroly Jean-Michel
Published: May 2022

Cet article étudie l’immigration française dans la Région de Bruxelles-Capitale d’un point de vue socio-démographique et géographique à l’aide de données statistiques individuelles et agrégées. Très concentrée dans les quartiers du Sud de la Région, cette population en forte croissante est caractérisée par une surreprésentation des jeunes adultes et des femmes. Elle comprend principalement des diplômé·es de l’enseignement supérieur mais est néanmoins polarisée entre des jeunes aux revenus faibles et des adultes en emploi bien rémunéré·es. À la différence des ressortissant·es des autres pays limitrophes de la Belgique, avec lesquels une comparaison est effectuée, les Franco-Bruxellois·es relèvent donc davantage de la Middle-Class migration (Scott, 2006) que d’une élite migrante transnationale.
Investir sous les cocotiers. Entrepreneuralisme immobilier et production de l’espace, le cas des Français de Las Terrenas
Authors: Chapon Laurine
Published: May 2022

Cet article analyse les modalités de la présence française dans une bourgade dominicaine, Las Terrenas. Les Français présents témoignent d’une diversité de profils, de statuts sociaux et résidentiels. Nous nous intéressons ici aux professionnels de l’immobilier et du tourisme, très nombreux parmi les Français, pour comprendre comment ils participent de manière centrale à la production de l’espace urbain en profitant et utilisant les instruments du droit à leur profit. La présence française participe à l’urbanisation et entraîne des processus de spéculation foncière et immobilière, dans un contexte de boom de la construction et d’augmentation des prix de l’immobilier. Nous analysons les conséquences de cette présence française sur les structures spatiales de Las Terrenas et nous réfléchissons également aux discours et registres mobilisés par ces acteurs pour légitimer leurs trajectoires entrepreneuriales : le droit joue un rôle central dans la naturalisation des rapports de domination.
Faire solidarité dans les politiques alimentaires de Nantes Métropole : tensions entre dynamiques participatives et affirmation d’acteurs publics
Authors: Fort-Jacques Théo , Marchadier Côme
Published: May 2022

Pour analyser les modalités de mise en place d’une gouvernance alimentaire métropolitaine et les manières dont les acteurs issus de la société civile y prennent part, nous proposons un focus sur les régimes d’interactions liés aux politiques de solidarité alimentaire dans un cadre particulier. Autour du Projet Alimentaire Territorial (PAT) de Nantes Métropole se déploient des scènes, des discours, des groupes de travail et des engagements de politique publique qui portent spécifiquement sur les solidarités alimentaires dans la transition écologique métropolitaine. L’ambition affichée vise à élaborer, par la participation d’une pluralité d’acteurs, une politique publique dont l’enjeu est de donner à chacun un accès à une alimentation « durable » ou écologique. L’observation des ateliers dédiés à la lutte contre la précarité alimentaire conduit à un constat paradoxal. Si le processus participatif joue un rôle de mise en réseau et de mise en visibilité d’une variété d’initiatives, il peine à déboucher sur des actions concrètes susceptibles de répondre aux enjeux de vulnérabilité. En revanche, l’ambition affichée par le PAT semble s’actualiser à travers les canaux classiques de l’action publique locale et en interaction avec le tissu associatif existant, dont les projets peuvent parfois se situer en contradiction de l’action métropolitaine.
Vers un renouvellement du dialogue entre agriculteurs et régions urbaines autour de l’accès au foncier agricole. Cas de la Métropole de Montpellier, France
Authors: Hasnaoui Amri Nabil , Michel Laura , Soulard Christophe-Toussaint
Published: May 2022

La participation des agriculteurs à l’action publique d’une métropole en matière d’alimentation locale est une question nouvelle. Elle met en relation une diversité d’acteurs agricoles et des acteurs urbains porteurs de nouvelles attentes environnementales et alimentaires qui doivent élaborer des solutions négociées. En s’appuyant sur l’analyse comparée de trois initiatives d’allocation de foncier agricole et naturel en périurbain de Montpellier, l’article met en évidence des formes variées de participation agricole à une politique agri-alimentaire territoriale. Une géographie de la participation agricole à l’alimentation urbaine est ébauchée : elle met en évidence le rôle de l’espace vécu des agriculteurs dans leurs façons de participer à une action publique locale. Elle souligne aussi le poids des modes d’action propres aux collectivités locales, notamment dans le champ de l’action d’aménagement.
L’autonomie alimentaire de Porto-Vecchio (Sud-Corse), entre initiatives locales et engagement politique
Authors: Tafani Caroline
Published: May 2022

À Porto-Vecchio (Sud-Corse), comme dans toute l’île, la population ne peut plus se nourrir sur la seule base du système agri-alimentaire local. Premièrement, 90 % des aliments consommés proviennent de l’extérieur du territoire. Ensuite, les produits locaux sont vendus à bon prix (voire à un prix très élevé) aux 3,5 millions de touristes qui visitent l’île. Par conséquent, la population locale souffre d’une d’injustice alimentaire. Cette situation nous amène à nous interroger sur les moyens mis en œuvre par les acteurs locaux pour aborder le concept d’autonomie alimentaire du territoire – question d’autant plus pertinente dans le contexte actuel de la crise du COVID-19 et du récent changement politique dans la municipalité de Porto-Vecchio. En effet, alors que semble s’installer un mouvement durable de territorialisation de l’alimentation se pose la question suivante : entre les initiatives locales et l’engagement politique de la nouvelle collectivité, l’autonomie alimentaire peut-elle être un concept pertinent pour penser le développement durable comme une nouvelle voie de développement pour cette communauté locale ?
Une coopérative habitante de paysage (CHP) en Haute Gironde : agir ensemble pour un projet alimentaire territorial
Authors: Epaud Grégory
Published: May 2022

Cet article propose de questionner les initiatives locales dans les projets de territoire et tente, dans le contexte de la crise socio-écologique actuelle, de dessiner les contours de nouvelles gouvernances territoriales. Plus précisément, il propose d’analyser les projets agri-paysagers d’acteurs organisés en coopérative habitante de paysage (CHP) et, sur ces bases, de comprendre de quelle façon ils participent à la mise en place et à l’animation d’un projet alimentaire territorial (PAT). L’hypothèse centrale est qu’installer une dialectique pragmatique entre le concept d’habiter et la notion de paysage permettrait de renouveler les différentes manières d’agir sur les lieux, d’aménager les territoires et de gérer les environnements. Il s’agit par-là d’explorer le champ d’initiatives à visée socio-écologique, qui réorganisent les relations à l’environnement des collectifs d’acteurs-habitants qui les portent. La démarche de recherche repose sur la mise en place d’un partenariat avec les acteurs-habitants du territoire étudié et sur des expérimentations visant à penser autrement les (re)configurations institutionnelles dans lesquelles se déploient les politiques publiques.

Authors: Mukhtar I.G. , Abdullahi A.
Published: May 2022

Occupational exposure to wood smoke and oil fumes is an important cause of respiratory problems. Meat roasting exposes workers to hazard of wood smoke and oil fumes. The aim of this study was to assess peak expiratory flow rate (PEFR) and other cardiometabolic parameters of meat roasters (Mai suya) in Kano, Nigeria. A total of 105 participants consisting of 55 meat roasters and 50 controls were recruited. All participants were assessed for PEFR, pulse rate, oxygen saturation, blood pressure, weight, height, and body mass index (BMI) according to standard protocols. Data were analyzed using SPSS version 23.0 and p value ≤ 0.05 was considered statistically significant. Mean age of the meat roasters and controls was 30.64±10.28 and 23.68±3.15 years. Meat roasters had statistically significant lower PEFR (243±85.35 vs 377.40±64.93 mL/min; p = 0.01), elevated diastolic pressure (81.91±6.64 vs 78.36±4.59 mmHg; p = 0.01), mean arterial pressure (94.12±7.96 vs 90.75±4.88 mmHg; p = 0.01) and BMI (19.53±2.40 vs 18.49±2.08 kg/m2; p = 0.02) compared to the controls. Number of years of working as meat roaster was positively correlated with systolic pressure (r = 0.67, p = 0.01), diastolic pressure (r = 0.41, p = 0.01), mean arterial pressure (r = 0.60, p = 0.01), BMI (r = 0.37, p = 0.01), and pulse rate (r = 0.46, p = 0.01). Meat roasting is associated with impaired lung function and altered blood pressure. Routine assessment of lung function and use of safety equipment should be encouraged among meat roasters.

Published: May 2022

This study was conducted to evaluate the most studied class among Fish, Amphibians, Reptiles, Birds and Mammals in Nigeria. Data were obtained from the Web of Science core collection from 1970-2020 with the inclusion of each class (“Fish” “Amphibians”, “Reptiles” “Birds” and “Mammals”) and country (“Nigeria”) as the search terms. The most studied class, fields within each class (Web of Science subject categories), most cited article and author, and affiliation with most publication were identified and used to reveal the most studied class in Nigeria. The results show that the class Fish with a total 536 publications, is the leading research focuses, most studied and had the highest number of publications, followed by Birds (214), then Mammals (52), Amphibians (30) and Reptiles (25) which is the least studied and with the least number of publications. It can be concluded that research on Fish remained the hotspot, whereas there is a paucity of data and research on Reptiles. Attention should be given to the least studied classes i.e. Amphibians and Reptiles so as to achieve a balance across the vertebrate classes.

Mining activities is one of the most significant sources of radiation exposure from long-lived naturally occurring radioactive materials (NORMs), and have resulted in unjustifiable public exposure doses which contravene radiation protection standards. As a result, estimating the extent of such exposure is essential for keeping the recommended public dose limit. This study therefore aims at estimating the public radiation dose around mining areas and its environs in some selected cities across Nigeria. Data on measured activity concentration of NORMs radionuclides comprising of U-238, Ra-226, Th-232 and K-40 from soil round mining areas in some selected cities in Nigeria were extracted from previous literatures and are used for public dose estimation using RESRAD computer code. From the calculated mean activity concentration, the results from each mining locations shows the maximum dose are lower than International Commission on Radiological Protection (ICRP), commended public dosage boundary of 1 mSv/yr with highest dose of 0.91 mSv/yr from Ra-226, Th-232 and K-40 over the period of 47.9 years reported from Gura Top mining site in Jos, Plateau State, while the lowest dose of 0.09 mSv/yr each over the period of 14.06 and 20.27 years occurred at Itagunmodi and Arufu sites for U-238, Th-232 and K-40. The highest dose recorded in Gura Top was due to numerous mining activities in the region. According to the ICRP, there is no safe level of radiation exposure. Therefore, there is need for competent authorities to conduct periodic assessment of radiation exposure from mining sites to ensure that all exposure emanating as a result of such activities are kept below the prescribed dose limit in accordance to the principle of As Low As Reasonably Achievable (ALARA), thereby ensuring public protection from unjustified radiation exposure.

Organochlorine and Organophosphorus Pesticides Residues in Commercial Poultry Feed Samples in Lagos State, Nigeria
Authors: Oluwole-Banjo A.K. , Agina P. , Umejiego R.
Published: May 2022

Pesticides are among Persistent Organic Pollutants (POP) used in agricultural practices to increase production efficiency. They enter the food chain, bioaccumulate and are toxic to human, animals and the environment. The presence of pesticide residues in animal feeds has been rarely monitored and reported in Nigeria. This study evaluated the levels of pesticide residues in different brands and types of poultry feeds that are produced, marketed and used in Lagos, Nigeria. Five types of five commonly used commercial brands (25 samples) of poultry feeds were purchased from animal feed markets in Lagos, Nigeria. Simultaneous detection and quantitation of selected thirteen (13) OCPs and eight (8) OPs residues in the feeds was carried out using Gas Chromatography-Electron Capture Detector (GC-ECD) and Gas Chromatography-Flame Ionization Detector (GC-FID) respectively. Results revealed that all the feed samples had multiple pesticide residues levels which ranged from 0.10 - 1.83 mg/kg for OCPs and 0.25 - 6.04 mg/kg for OPs. These values were above the Maximum Residual Limit (MRL). The detected pesticide residues order of violation of the MRL was Methoxychlor > Dieldrin >Endrin ketone for OCPs, and Trichlorfon > Malathion > Diazinon for OPs. There was no significant (p>0.05) differences in the pesticide residues levels among the brands and types of the samples. Present study indicates extensive and unwholesome use of pesticides in the agro industry in Nigeria suggesting need to enforce Good Agricultural Practices (GAP), Good Storage Practices (GSP), Good Manufacturing Practices (GMP) and constant monitoring of pesticide residues thereby implementing the Good health and Wellbeing (Goal 3) of the 2030 Sustainable Development Goal.

The median lethal dose (LD50) of Abrus precatorius seeds aqueous extract was determined via intraperitoneal (i.p.) rout of administration before screening the effect of the extract on the liver. In this study, age matched Wistar rats (180-190 g) were grouped into four with five rats per group. The treatment groups were administered 0.025 mg/kg, 0.05 mg/kg and 0.10 mg/kg aqueous extract of A. precatorius seeds (i.p) while the control group was administered 10 ml/kg distilled water (i.p) daily for fourteen days. At the end of the study, the activity of enzymes (alanine transaminase [ALT], aspartate transaminase [AST] and alkaline phosphatase [ALP]) present in the serum and liver homogenate was evaluated. The relative organ (liver) weight (ROW) and the effect of the extract on the histology of the liver were also determined. The results showed that the LD50 of A. precatorius seed was 0.35 mg/kg (i.p). A. precatorius seed extract caused an increase in ROW and in the activity of enzymes (ALT, AST and ALP) at 0.05 and 0.10 mg/kg when compared with the control. Pathological changes were observed in rat liver of treatment groups. In conclusion, the aqueous extract of A. precatorius seeds could be toxic to the liver and caution should be exercised in its use in traditional medicine.

Authors: Xiao Qiaosu , Li Ting , He Wenyang
Published: May 2022

Purpose: To investigate the effect of decursinol angelate in acute lung injury induced by lipopolysaccharide treatment.

Methods: Human bronchial epithelial cells (BEAS-2B cells) and human pulmonary artery endothelial cells (HPAECs) were exposed to lipopolysaccharide to induce cell injury and then treated with 20, 40, or 60 μM decursinol angelate. Cell viability was quantified using a cell counting assay, while cell apoptosis was evaluated by western blot and flow cytometry. Colorimetric and enzyme-linked immunosorbent assay (ELISA) was used to measure oxidative stress. Expressions of tumor necrosis factor-alpha (TNF-α), interleukin-1β, and interleukin-6 were evaluated using quantitative real-time-polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA). Phosphorylation levels of p65, IκBα, AKT, and phosphatidylinositol 3-kinase were assessed by western blot, while the entry of p65 into the nucleus was investigated by indirect immunofluorescence assay.

Results: Treatment with 40 or 60 μM decursinol angelate increased cell viability after lipopolysaccharide-induced damage. B-cell lymphoma 2 (Bcl2) and Bax expression were regulated, and the rate of apoptosis was inhibited. The concentration of superoxide dismutase and glutathione was elevated, and the density of malondialdehyde and myeloperoxidase decreased significantly. Inflammation was also suppressed by decursinol angelate by regulating TNF-α, interleukin-1β, and interleukin-6 expressions. Furthermore, decursinol angelate significantly decreased the phosphorylation of p65, IκBα, AKT, and phosphatidylinositol 3-kinase. Finally, decursinol angelate inhibited p65 entry into the cell nucleus.

Conclusion: Decursinol angelate alleviates cell damage and apoptosis, reduces oxidative stress, and attenuates inflammation after lipopolysaccharide-induced acute lung injury by inhibiting AKT/NF-κB signaling pathway. Thus, decursinol angelate is a potential candidate for the treatment of lung injury.

Published: May 2022

Purpose: To determine the effect of the ethanol leaf extract of M. calabura (EEMC) on cell leakage and time-kill against S. aureus.

Methods: The leaves were macerated with 96 % ethanol (1:8; w/v) for 27 h to produce EEMC. Chemical compounds of EEMC were analyzed using liquid chromatography with tandem mass spectrometry (LC-MS/MS). Various concentrations of EEMC (12.5; 25; 50; 100 mg/mL) were tested to determine the Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against S. aureus. Furthermore, EEMC was tested for its effect on cell leakage, changes in extracellular electrical conductivity, and time-kill against S. aureus. UV-spectrophotometer was used to test for leakages of nucleic acid, protein, DNA, and RNA, while atomic absorption spectrophotometer was used to evaluate leakage of potassium ion (K+).

Results: The MIC and MBC of EEMC against S. aureus were 10 % w/v (100 mg/mL). The highest cell leakage occurred in S. aureus exposed to 2x MIC, with leakages of protein, DNA, RNA, and K+ reaching 137.79 ± 58.99, 2298 ± 263.26, 1839 ± 210.61 and 770.86 ± 40.11 μg/mL respectively. The EEMC (1x MBC and 1.5x MBC) killed S. aureus in 24 h. Analysis of LC-MS/MS of EEMC showed that flavonoids (48.33 %) followed by anthraquinones (16.10 %) were the major classes of compounds present in the extract.

Conclusion: The ethanol leaf extract of M. calabura kills S. aureus by inducing cell leakage possibly due to flavonoids and anthraquinones contained in it. The extract should be further isolated and its active principles with potent antibacterial properties developed for therapeutic applications.
Investigation of the potential pharmacological mechanism of action of Danhong injection against chronic heart failure using a network pharmacol ogy based approach
Authors: Lin Ruzheng , Li Wei
Published: May 2022

Purpose: To investigate the mechanism of action of Danhong Injection (DHI) in chronic heart failure (CHF).

Methods: Network pharmacology was employed to identify the bioactive compounds and targets of DHI in CHF. Bioinformatics analysis was used to examine the potential biological functions and pathways of the candidate targets, while molecular docking was conducted to evaluate the binding affinity of the ligand-protein complex.

Results: Based on data mining from public databases, 65 bioactive ingredients and 246 potential targets of DHI were identified, along with 786 CHF-related genes. There were 48 common targets between DHI targets and CHF-related genes, and a protein-protein interaction (PPI) network of common targets containing 42 nodes and 204 edges was constructed. The 48 common targets were considered as effector proteins exerting anti-CHF effects, and they were shown to be involved in multiple signal-transduction pathways and disease-related pathways by bioinformatics analysis. Most of these targets had protein-binding capability and were located in plasma membrane as well as extracellular regions. The biological process of these proteins was primarily associated with gene regulation, response to hypoxia, and heart development. Binding capability between these active ingredients and proteins was further validated by molecular docking simulation.

Conclusion: This study has shed new light on the pharmacological mechanism of action of DHI’s effects on CHF, thus offering fresh leads for additional research into DHI's potential to cure CHF.

Authors: Wang Yu , Li Chengling , Peng Keyun
Published: May 2022

Purpose: To determine the efficacy and safety of locally-applied vancomycin powder injection as precaution against prosthetic joint infection (PJI).

Methods: A total of ninety subjects on admission in Department of Limb and Joint Surgery, PLA Medical Center, who underwent surgery for arthroplasty of knee and hip, were selected for this study. They were divided into two groups comprising control group (n = 45) given routine preventive antibiotic therapy as well as treatment group (n = 45) which received routine prophylactic antibiotics in combination with vancomycin therapy. PJI and the incidence of adverse reactions within 3 months after surgery were recorded. Body temperature of the patients was recorded with a thermometer. The number of neutrophils was measured by flow cytometry, while the expression levels of IL-6 and hs-CRP in peripheral blood were determined using enzyme-linked immunosorbent assay (ELISA) preoperatively and at 24, 72 and 168 h post- therapy.

Results: At 90 days post-therapy, there was obviously significant reduction in the degree of PJI in the vancomycin-treated subjects compared with control group (p > 0.05). Moreover, within 3 days, normothermia, lowered neutrophil population and downregulated expressions of Il-6 and hs-CRP were seen in the vancomycin group, when compared to control subjects (p < 0.05). However, there was no significant difference in the incidence of adverse reactions between the treatment and control groups after therapy (p > 0.05).

Conclusion: Topical application of vancomycin powder injection is safe, and regulates the body temperature of PJI patients in the short-term after surgery. Moreover, it decreases the levels of inflammatory indices. However, further clinical trials should be carried out prior to application in clinical practice.
