Le référentiel « cinq piliers de la maîtrise de l'information scientifique » : élaboration et construction de l'outil
Authors: Pochet Bernard , Durieux Nancy , Collette Caroline , Decoster Sara , Dieudonné Mélodie , Vandenput Sandrina 
Published: March 2021

La maîtrise de l'information scientifique est une préoccupation majeure des bibliothécaires impliqués dans la formation des usagers. À l’Université de Liège (Belgique), un référentiel a été créé afin de cartographier les savoirs, savoir-faire et attitudes nécessaires à la recherche, à l’évaluation et à l’utilisation des publications issues de la recherche scientifique. Il a pour finalité de contribuer à l'élaboration, l’amélioration voire l’évaluation, de cours et formations ayant pour objectif la maîtrise de l’information scientifique. Ce référentiel, appelé les « cinq piliers de la maîtrise de l'information scientifique » (5PMIS), a été développé à partir de la consultation d'autres référentiels, de l'avis de 32 enseignants et chercheurs ainsi que de l'analyse des cours dispensés à l’Université de Liège. Après relecture par des membres internes ou externes à l’Université de Liège, le référentiel a été mis en ligne en septembre 2017. Outil de cohérence et de collaboration entre les bibliothécaires-enseignants de l’ULiège Library, le 5PMIS couvre les trois secteurs de connaissance représentés à l'Université, à savoir les sciences humaines, les sciences et techniques et les sciences de la santé. Il se concentre sur le contexte académique et prend en compte différents niveaux de développement dans le parcours universitaire.L’objectif de cet article est de décrire la création de ce référentiel, conçu pour que tout formateur puisse se l'approprier en fonction du type de public visé. Il n'est pas uniquement destiné aux professionnels de l'information et aux bibliothécaires. L'intérêt est qu'il puisse aussi être mobilisé dans des approches transversales, par des enseignants d'horizons divers. Bien que développé pour l’Université de Liège, le 5PMIS peut ainsi être utilisé et adapté par d'autres établissements de l'enseignement supérieur, universitaire ou non universitaire.
Coronavirus Anxiety Scale
Authors: Singh Khundrakpam Devananda 
Published: March 2021

Background and Objective:
Coronavirus is spreading across the globe since December 2019. As India's first case was reported on January 30, 2020, the spread of this virus is experiencing by our population. As a result, there are extensive emotional distress and anxiety among populations due to this pandemic. Screening mental health is important for psychological well-being of any individual during this pandemic. The objective of this study was to validate the Coronavirus Anxiety Scale (CAS) in an Indian population.

Materials and Methods:
The research proposal was laid out before an ethical clearance committee, which approved the conduct of the research and consequent publication of the paper. Data were collected from 246 respondents through online. CAS, developed by Lee (2020), was adopted for the study. Informed consent was given by all the respondents, and their participation was voluntary. AMOS and SPSS were used to calculate confirmatory factor analysis and other statistical analyses. Bartlett's test of sphericity and Kaiser–Meyer–Olkin (KMO) test, and Cronbach's alpha, were also calculated. Convergent validity was calculated through average variance extracted (AVE) and composite reliability (CR) in Microsoft Excel.

Results, and Conclusions:
Bartlett's test of sphericity was highly significant measuring Chi-square = 494.004, df = 10, and P < 0.001. The KMO was acceptable at 0.805. Fit indices (P < 0.001, Chi-square/df = 3.24, goodness of fit index = 0.976, Tucker–Lewis index = 0.954, and comparative fit index = 0.977) are statistically significant. Cronbach's alpha coefficient (0.822), AVE (0.526), and CR (0.745) were adequate. The overall findings of the analyses demonstrate that the CAS is a reliable and valid scale that evaluates the severity levels of dysfunctional anxiety linked to COVID-19 in an Indian sample. CAS is applicable to measure the level of dysfunctional coronavirus anxiety in the Indian population.

Published: March 2021

This study assessed extension agents’ use of mobile applications (apps) for extension service delivery in Ebonyi State Agricultural Development Programme (EBADP). The study involved 100 field extension agents. Percentage and mean score derived from 4-pointLikert-type scale was employed in the analysis of data. The results of the analysis showed that the most utilized mobile apps for extension service delivery were WhatsApp (76%) and facebook (53%). Lowland rice production (65%), cassava/maize/vegetable production (58%), and upland rice production (47%) were the most recommended packages of crop production component that were extended using mobile apps in EBADP. However, the use of mobile apps for extension service delivery were limited as a result of unavailability of network coverage in rural area (84%), lack of institutional policy for application of mobile apps in extension service (75%), low ownership of smartphones among farmers (73%), poor farmers’ knowledge on the use of mobile apps (67%), and poor internet connectivity (66%). Government should initiate e-extension policy, making mobile apps extension services mandatory for public extension organizations; extension organizations should develop specific mobile apps that will support extension service delivery; and organizing training programmes for extension agents on the use of mobile apps for extension service delivery.

Published: March 2021

Petrophysical-Modelling is indispensable in upstream Projects, considering the high cost, risks and uncertainties associated with this sector. Petrophysical qualities for Queen Field was modeled using Information obtained and analyzed from well-logs and 3-D Seismic data. Coarse-grain, Medium- grain and fine-grain Sands as well as Shale were all delineated by GR log. Results of petrophysical evaluation conducted on seven reservoir intervals correlated across the field showed that; Shale volume was below 35%, Total Porosity are > 20% Effective Porosity are >15% Permeability is > 380.00mD all of this conforms to excellent reservoir quantity. Seismic interpretation showed the presence of synthetic and antithetic faults. Two horizons were mapped on seismic data and utilized for modeling. These models were the framework for facies and petrophysical properties distribution. Facies models were generated using sequential indicator simulation while petrophysical properties were generated using sequential gaussian simulation algorithm. A comparison was further done between facies constrained and non-facies constrained models. It was found that for Porosity, Permeability, Water of Saturation and Shale Volume Models not constrained to facies all showed overestimated Models, in addition Stochastic STOIIP not constrained to facies gave an Over Estimated P50 value for Surface I and O Reservoir Interval as 624.028M, 76.28MM, when compared to Stochastic Hydrocarbon STOIIP when constrained to facies that showed Stochastic P50 value of 513,247 and 67.04MM for surface I and O and Deterministic STOIIP of 742.90M and 87.88MM. This study validates the practice of constraining Petrophysical model to facies available on the field as the best practice.

Authors: Omokanye BS , Mustapha OT , Abdulrahaman AA , Kolawole OS 
Published: March 2021

Studies of the foliar epidermal morphology in four species of Chlorophytum; C. orchidastrum, C. bichetii, C. stenopetalum and C. macrophyllum revealed the presence of stomata on both sides of the leaves (amphistomatic stomata distribution). In C. orchidastrum, few stomata are present on the adaxial surfaces. Stomata type has no diagnostic importance as all the species studied have tetracytic stomata. Stomata index (<10%) on the adaxial surface in C. orchidastrum easily distinguished the species from others. In C. bichetii and C. macrophyllum stomata index (<50%) was recorded while stomata index (>50%) was recorded for C. stenopetalum on the adaxial surface. Stomata index on the abaxial surface also shows that fewer stomata occur in C. macrophyllum compared with C. stenopetalum. The studies also revealed smooth leaf margin for C. orchidastrum. Papillea out growth were observed on the leaf margin of C. stenopetalum and C. macrophyllum, Papillea projections were however more pronounced in C. bichetii. Leaf epidermal character is hereby indicated as an important tool in delimiting species in the genus Chlorophytum.

Hydrocarbon Generation Potential of the Campano-Maastrichtian Dark Mudstone Lithofacies, Benin Flank, South West Anambra Basin, Nigeria
Authors: Edegbai AJ , Emofurieta WO 
Published: March 2021

The dark mudstone lithofacies of Mamu Formation was deposited during the Campano-Maastrichtian flooding episode. It is laterally heterogeneous, and has been subdivided into marsh, bay and central basin subenvironments in order of proximality. Arising from recommendation from a previous study, we evaluated its hydrocarbon generating potential using multidisciplinary tools involving visual kerogen analysis, as well as bulk and isotope geochemistry. Seventy-seven sample materials were taken from 3-outcrop sites at Uzebba, Okpekpe and Imiegba locations, Benin flank, SW Anambra Basin, Nigeria. The results show that bulk of the samples have good organic richness. Kerogen quality is dominantly of gas prone Type III kerogen. However, visual kerogen analysis indicates the presence of an oil prone Type II/III kerogen in the central basin subenvironments. An immature thermal maturity is inferred based on spore colour index (SCI) of less than 6 on the SCI chart (thermal alteration index of <2.5). In addition, we hypothesize that the dark mudstone lithofacies possesses biogenic gas potential based on its organic richness, kerogen quality and thermal maturity. Shale gas prospectivity is further enhanced by the low dip of the Mamu Formation, shallow burial as well as high silica content. Worth mentioning is the proximal marsh mudstone (Uzebba location) with suitable microfabric, very high silica as well as >10m of combined (continuous) outcropping and subcropping thickness

Study on assessmentof biodiesel fuel potentials of seed crude oil extracts of Balanites aegyptiaaca (L.) Del was carriedout. Standard methods of the Association of Official and Analytical Chemist (AOAC) were adopted to evaluate the proximate, physico-chemical properties and fatty acid compositions of crude seed oil extracts of the test plant. The proximate constituents of the crude seed oil extract gave crude protein (22.09%), crude fat (56.75%), moisturecontent (1.35%), ash (4.70%), crudefiber (12.75%) and carbohydrate (2.36%). The crude oil physicochemical properties included saponification value(216.439mgKOH/g), peroxide value(4.84meq/kg), acid value(2.18mgKOH/g), iodine value(77.08g/100g), viscosity value(150.3@30°C) and cetane number(54.08), refractive index(1.487 @30°C), relative density (0.949g/cm3) while calorific value was 39.03(MJ/kg). The fatty acids composition of crude kernel oil extract of B. aegyptiaca indicated the presence of four (4) fatty acids, with relative percentage abundance (RPA) in the order of 67.17% (9,12-Octadecanoic acid (C19 H3402)) > 16.22% (Pentadecanoic acid (C17H3402)) > 11.8kg% (Heptacosanoic acid (C28H5602)) > 4.72% (Oleic acid(C18H3402)). These properties conferred relative prospects on the crude oil of the test plant as a suitable potential biodiesel substrate and consequently, large scale aforestation efforts be renewed, to guarantee ready availability of the raw materials.

Globally, infectious bronchitis (IB) is an important respiratory viral disease responsible for enormous economic losses to poultry farmers. In Nigeria, limited reports on the prevalence and serotypes of the IB virus are available. Here, we investigated the prevalence and serotypes of infectious bronchitis virus (IBV) in chicken in Plateau State. A descriptive cross-sectional study was carried out involving 440 apparently healthy free-range local chickens sampled from eleven villages in four Local Government Areas (LGA) of Plateau State. Sera collected from the birds were screened for the presence of four IBV serotypes namely; Massachusetts (Mass), Arkansas (Ark), Connecticut (Con) and Delaware (De-072) using haemagglutinationinhibition (HI) test. In all, a prevalence of 82.95% (n = 365) was recorded. At LGAlevel, prevalence of 79.50%, 47.37%, 95.45% and 100% were recorded in Kanam, Mangu, Qua’an pan and Bassa LGAs, respectively. Based on serotype prevalence, Mass had 89.30% (n = 326); Ark 79.70% (n = 291); Con 88.20% (n = 322) while De-072 was 42.70% (n = 156). There were statistically significant associations between dominant serotype and the LGAs (p≤0.001). This study shows high prevalence of IBwith at least four strains of IBV present in free-range chicken flocks in Plateau State requiring attention for control measures.

A five-month-old female Boerboel puppy presented with a rapidly expanding fibrous growth around the canine tooth of the right maxilla was diagnosed as having acanthomatous ameloblastoma based on findings from skull radiography, cytology of fine needle aspiration, biopsy and histopathology of resected growth. Lateral radiograph of the skull revealed moderate osteolysis of the maxilla with presence ofun-erupted maxillary canine teeth. Cytology of fine needle aspirate from the growth showed clusters of epithelial cells that were hyperchromatic and showing palisade arrangement. The mass was surgically resected using diathermy instrument following general anaesthesia using combination of intramuscular injection of xylazine (0.5mg/kg), and intravenous injection of propofol (4mg/kg). Post-operative management included Ibuprofen suspension (100mg) administered for 3-days, intravenous vincristine (0.5mg/m2 ) once weekly and oral cyclophosphamide (50mg) was administered twice weekly for six weeks. Histopathology of the growth showed odontogenic epithelium embedded in pulp ectomesenchyme. Features of odontogenic epithelium include palisading epithelium with anti-basilar nuclei and centrally located cells having features of stellate reticulum. This is probably the first reported case of acanthomatous ameloblastoma in a Boerboel puppy that was successfully managed.

Purpose: To investigate the antioxidative and memory-enhancing effects of aqueous extract of unpolished Thai rice strain of Luem Pua (LP) in SK-N-SH cells and scopolamine-induced memory deficit in mice.Methods: In SK-N-SH cells, viability was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT) assay while intracellular reactive oxygen species (ROS) levels were quantified after pretreatment with LP (0, 200, 600 and 1000 μg/mL) in the presence of hydrogen peroxide (H2O2). In mice, memory was impaired by injecting 2 mg/kg/day scopolamine, for 18 consecutive days. On each day, mice were also force-fed with LP 0, 90 or 180 mg/kg. On the last 5 days of treatment, memory was tested using passive avoidance (PA) and Morris water maze (MWM) tests.Results: At concentration up to 1,000 μg/mL LP had no effect on SK-N-SH cell viability and significantly reduce intracellular ROS levels of SK-N-SH cells with or without H2O2. Mice that received 90 or 180 mg/kg LP showed a significant decrease in latency time in PA test and an increase in escape latency time in MWM test. These data suggest that LP antagonizes the effect of scopolamine on memory.Conclusion: LP extract has anti-oxidative and memory-enhancing effects in cell culture and mice. The rice may be a nutraceutical helpful for promoting brain health. Keywords: Dark purple rice, Leum Pua rice, Reactive oxygen species, Memory, Scopolamine, Cell culture

Authors: Luan B , Sun C 
Published: March 2021

Purpose: To investigate the effect of dimedone pyrone (DP) on podocytes in rats with diabetic nephropathy (DN).Methods: The rats were randomly assigned into 5 experimental groups (n = 10), viz, non-diabetic control with no treatment (ND/NT), diabetic with no treatment (DG/NT), diabetic treated with 5 mg/kg dimedone pyrone (DG/DP 5), diabetic treated with 10 mg/kg dimedone pyrone (DG/DP 10) and diabetic treated with 20 mg/kk dimedone pyrone (DG/DP 20) group. Clinical parameters, including 24 h urinary protein, blood urea nitrogen (BUN), serum creatinine (SCR), blood glucose (GLU), and kidney weight (KW)/body weight (BW) were determined after 12 weeks of treatment. Hematoxylin and eosin staining was used to examine renal pathological changes while transmission electron microscopy (TEM) was employed for evaluation of structural changes in the podocytes. The expression levels of nephrin and podocin were evaluated using immunofluorescence staining.Results: Dimedone pyrone caused a significant decrease in SCR, BUN, GLU, KW/BW and 24 h urine protein in DG/DP 20 group compared to DG/NT group. Furthermore, incidences of glomerular disorders, chronic tubulo-interstitial damage and glomerular podocyte lesions decreased significantly following dimedone pyrone treatment. Glomeruli, tubules and podocytes exhibited pathomorphological improvements while nephrin and podocin protein expression levels were significantly higher in the nephridial tissue. Decrease in relative kidney weight (KW/BW) and 24 h urinary protein level were improved significantly on treatment with dimedone pyrone. Moreover, glomerular disorder, chronic tubulo-interstitial damage and glomerular podocyte lesions were also suppressed. The improvement was more significant in DG/DP 20 compared to DG/DP 5 and DG/DP 10 groups.Conclusion: Dimedone pyrone exhibits a protective effect on the podocytes of rats and may be of therapeutic importance in the treatment of diabetic nephropathy.Keywords: Dimedone pyrone, Podocin, Diabetic neuropathy, Nephrin, Glomerular disorders
MiR-384 is associated with renal damage in lupus nephritis via regulation of TET3 expression
Authors: Zhang Jun , Lu Suli , Ding Ting , Zhao Haijia , Tang Dongxing 
Published: March 2021

Purpose: To investigate the correlations between miR-384 expression and renal damage in lupus nephritis (LN).Methods: Lupus nephritis and normal tissues were collected during surgery. The relative miR-384 expression was evaluated by extracting RNA and performing quantitative real time PCR (qRT-PCR) assays. Expression of ten-eleven translocation (TET3) mRNA and protein were measured by qRT-PCR and western blotting, respectively. The 24-h urine protein, serum complement C3, and serum creatinine were determined using commercial enzyme-linked immunosorbent assay (ELISA) kits. TargetScan and luciferase assays were used to validate the binding site for miR-384 and its target mRNA. Relationships among miR-384, TET3, and renal damage were analyzed by Spearman rank-order correlation coefficients.Results: MiR-384 expression increased in LN tissues and was positively correlated with the activity index (AI) and chronicity index of LN, whereas miR-384 expression and serum complement C3 were negatively correlated. Positive correlations were observed between miR-384 expression and 24-h urine protein, serum creatinine, and systemic lupus erythematosus disease AI. TargetScan and luciferaseassays indicated that the TET3 3′-UTR was the direct target of miR-384. MiR-384 upregulation inhibited TET3 mRNA and protein expression, and was negatively associated with renal damage in LN.Conclusion: MiR-384 upregulation contributes to renal damage in LN by targeting the 3′-UTR of TET3 mRNA, suggesting that miR-384 is a potential biomarker and therapeutic target in LN.

LncRNA PFAL suppresses TNF-α-induced inflammation by upregulating miR-18a in WI-38 cells
Authors: Xie Yichun , Wang Hongqun 
Published: March 2021

Purpose: Pneumonia is a serious respiratory disease among children with high mortality and morbidity all over the world. Long non-coding RNAs have been proven to play a vital role in many inflammatory diseases including pneumonia. In the present study, the protective impact of lncRNA PFAL on cell viability, cell apoptosis and secretion of inflammatory cytokines, as well as the underlying molecular mechanism in TNF-α-induced inflammatory injury model of pneumonia were investigated.Methods: WI-38 cell line was treated with 20 ng/ml TNF-α to establish an inflammatory injury model of pneumonia. LncRNA PFAL or miR-18a was up- or down-regulated in the WI-38 cells by transfection procedure. Cell viability was assessed using CCK-8 assay, while the rate of cell apoptosis was measured by utilizing flow cytometry. The mRNA expression levels of lncRNA PFAL, miR-18a, apoptosis-related and JNK pathway genes were determined with RT-qPCR. Moreover, the production of inflammatory cytokines such as IL-6 and MCP-1 were detected by using Western blot analysis.Results: The results indicated that cell viability was significantly (P<0.05) reduced, while the rate of cell apoptosis was increased in the TNF-α-induced WI-38 cells. Also, TNF-α treatment enhanced the expression of inflammatory cytokines that included IL-6 and MCP-1 in WI-38 cells. Overexpression of PFAL suppressed the injury induced by TNF-α and miR-18a was positively regulated by PFAL. Moreover, the inhibition of miR-18a weakens the effect of PFAL overexpression in TNF-α-induced cell injury. Furthermore, PFAL and miR-18a were involved in the regulation of JNK pathway.Conclusion: Overexpression of PFAL suppresses TNF-α-induced WI-38 cell injury by up-regulating miR-18a via the inactivation of JNK signaling pathway.
