88, TPC of 4.75 g/l, COD of 80 g/l, BOD5 of 18.72 g/l, conductivity of 16.05 cm-1, dry matter of 135.7 g/l and volatile matter of 58.7 g/l. The adsorption on clay had increased the pH from 4.88 to 6.14 and reduced significantly the organic matter (42% of COD and 57.4% of phenolic compounds). UHPLC-ESI-MS analysis showed the presence of a wide variety of organic compounds in OMW, with the appearance of new compounds after adsorption. Moreover, the use of treated OMW as a source of irrigation showed a significant effect on the germination of Lepidium sativum seeds and the growth of Vicia faba plants. From this study, we can conclude that the adsorption on clay is a good method for the treatment of OMW, which became non-toxic for environment and can be used as a source of irrigation in agricultural field. © 2020 Published by Elsevier Ltd.Measurement of the antioxidant potential using in vitro assays is paramount in the assessment of various food products and nutraceuticals. Researchers always attempt to develop more accurate assays which can be performed in unsophisticated conditions. This novel method, Ferric-Bipyridine reducing capacity of total antioxidants (FBRC) is a very simple, accurate assay performed based on the reduction of Fe (III) to Fe (II) by antioxidants with the formation of a colored complex with bipyridine (Bp) i.e, Fe(II)-Bp. The FBRC method thus developed was assessed under carefully adjusted parameters of oxidant concentration, pH, temperature, solvent, light and time in order to fix the optimum conditions for the assay. The spectrophotometric monitoring of Fe(II)-Bp complex was noted by the formation of an intense pink color at room temperature with absorption maxima at 535 nm, pH 4. The analytical performance of this method was fully validated, and the obtained results were satisfactory. It was successfully applied to measure the total antioxidant capacity of standard compounds such as gallic acid, ascorbic acid and butylated hydroxy toluene (BHT), in addition to some plant extracts and oils. The FBRC method is inexpensive, reproducible and simple to perform. In addition, the antioxidant activity of the tested compounds compared to common reference methods showed that the novel FBRC method is superior to the Ferric reducing antioxidant power (FRAP) with regard to its use of realistic pH and faster kinetics. Thus, the FBRC method is convenient for the estimation of total antioxidant in plants extracts, natural products, essential oils and food stuff. © 2020 The Authors.In-silico activity prediction was performed to predict new inhibitory activities of 2, 9-disubstituted 8-phenylthio/phenylsulfinyl-9h-purine derivatives as anti-proliferative agents using QSAR technique. The anti-proliferative agents were optimized using Density Functional Theory (DFT) method utilizing the B3LYP/6-31G* level of theory. Genetic Function Algorithm (GFA) was used to build the QSAR models. Out of the models built, the best one was selected and reported because of its fitness statistically with the following assessment parameters R2 trng = 0.919035, R2 adj = 0.893733, Q2 cv = 0.866475, R2 test = 0.636217, and LOF = 0.215884. The selected model was further subjected to other assessment such as VIF, Y-scrambling test, applicability domain and found to be statistically significant. The binding mode of some selected 2, 9-disubstituted 8-phenylthio/phenylsulfinyl-9H-purine (ligands) in the active site of EGFR-tyrosine kinase (EGFR-TK) (receptor) was studied via Molecular docking. Molecule 22 was identified to have the highest binding energy (-10.4 kcal/mol) among the other selected ligands which it might be as a result of hydrogen interactions formed with MET793 (2.48599 Å, 2.04522 Å) & THR854 (3.76616 Å) amino acid residues and hydrophobic/other interactions with amino acid residues (LEU718, LEU844, MET766, VAL726, ALA743, LYS745 and MET790) in the active site of EGFR-tyrosine kinase (EGFR-TK). The drug-likeness of these selected anti-proliferative agents were predicted via the pharmacokinetics profile of the molecules utilizing SWISS ADME. The anti-proliferative agents were found to be orally safe by not having more than 1 violation of the Lipinski's rule of five. This research proposed a way for designing potent anti-proliferative agents against their target enzyme. © 2020 The Authors. Published by Elsevier Ltd.Information regarding the menstrual knowledge and practices of Pakistani girls is sparse. Therefore, we aimed to evaluate the knowledge and practices of Pakistani girls regarding menstruation. This cross-sectional study was conducted among four categories of university female students of medical, pharmacy, nursing, and arts & humanities during a period of 5 months (November 2016-March 2017). The data were acquired using a self-administered questionnaire from 3 medical institutes, 2 pharmacy institutes, 3 nursing institutes and 2 arts & humanities institutes at Lahore, Pakistan. The mean age of participants (N = 1777) was 20.38 ± 2.39 years. Overall 39.5%, 76.1% and 29.3% respondents' provided correct answers to the questions concerning menstrual cycle length, duration of menstrual bleeding and source of bleeding, respectively. Regarding the understanding of menstruation, around 27% understood it as monthly bleeding happening with every woman, whereas 18% stated that it was a sign of adulthood. However, a small proportion believed that it was removal of dirt from the body. Regarding the practices-related to menstruation, there were some malpractices regarding diet and dietary intake (avoiding certain foods, eating less, and less fluid intake). However, the hygienic practices were found to be satisfactory. In conclusion, Pakistani university girls have some misconceptions, misperceptions and malpractices related to menstruation. Our findings draw attention to conduct awareness programs in order to eradicate these misconceptions, myths and malpractices. © 2020 The Authors.

Green synthesis method was proposed because it is cost effective and environmentally friendly. ZnO was characterised using SEM, EDX, FTIR, and XRD analyses. The antibacterial property was tested against Escherichia coli. The effects of aloe vera volume (2-50) mL, precursor concentration (0.001-0.300) M, reaction time (20 min-48 h), and temperature of the reaction (26-200) °C on ZnO characteristics were investigated and screened using a two-level factorial method. Based on the observation and ANOVA analysis result, precursor concentration was the only significant parameter that affected the production of the ZnO nanoparticles (NPs). The EDX analysis proved the presence of ZnO while the SEM analysis confirmed the average size of ZnO particle size was in the range of (18-618) μm with a rod-shape appearance. The XRD analysis showed that the average crystallite size was 0.452 μm and it was in the hexagonal phase. It was also proven to have antibacterial property against E. coli. © 2020 The Authors. Published by Elsevier Ltd.Genetic diversity is fundamentally important in crop improvement and provides plants with the capacity to meet the demands of changing environments. This work was carried out to assess the diversity and the extent of genetic relatedness among a number of assembled cassava (Manihot esculenta Crantz) accessions. We conducted a microsatellite marker analysis of 89 cassava accessions collected from Ghanaian and exotic sources. These accessions were assayed using 35 simple sequence repeat (SSR) markers. A total of 167 alleles were detected from 35 polymorphic markers with an average of 4.77 alleles per locus. High allelic frequency was detected across the accessions, ranging from 0.32 to 0.99 with an average of 0.62 per marker. Observed heterozygosity ranged from 0.03 - 0.97 across the accessions. Polymorphism information content (PIC) ranged from 0.03 to 0.78 with a mean of 0.45, indicating high level of polymorphism across the accessions. Comparatively, higher number of alleles, gene diversity and observed heterozygosity were detected among the local accessions compared with the exotic accessions indicating rich genetic diversity among them. Population structure analysis based on STRUCTURE identified two subpopulations and a large number of admixtures. Cluster analysis based on the neighbour joining algorithim further separated the collection into seven sub-groupings irrespective of geographical origin. This indicates the possible sharing of common genomic regions occurring across the accessions. High allelic frequency differences and levels of heterozygosity were observed among the germplasm. These findings indicated significant genetic variability in the germplasm to warrant selection. © 2020 The Author(s).Several parameters of the Novichok nerve agents A230, A232 and A234 were determined. EZM0414 research buy Hydrolysis rates were approximately one to three orders of magnitude slower than G-type nerve agents and approximately zero to two orders of magnitude slower than V-type nerve agents. A230 was the most labile Novichok compound followed by A232 then A234. Activation energies (Ea) and frequency factors (A) were determined for all three compounds. The organophosphorus acid anhydrolase (OPAA) enzyme had catalytic efficiencies on the Novichok compounds ranging between 104 and 105 M-1 min-1 with the highest k cat/Km value for A230, then A232 and lastly, A234.Visceral leishmaniasis (VL) or kala-azar is a tropical disease, which is caused by an obligate intracellular parasite of the genus Leishmania. It is transmitted by the bite of an infected phlebotomine sand fly. The disease is endemic in northwest part of Ethiopia particularly in areas bordering Sudan. Assessing the knowledge, attitude and practices (KAP) of the community is helpful to design and implement appropriate control and prevention strategies. A cross-sectional study was conducted to assess the KAP of the resident community on VL in West Armachiho district, northwest Ethiopia. Data were collected by using pretested and well-structured questionnaire. Two villages (Abderafi and Abrehajira) were selected randomly. Households engaged in the study were selected by systematic random sampling method and then finally, simple random sampling was used to engage a maximum of two individuals per household. A total of 422 participants were engaged in the study. Almost all participants heard about VL. The source of information was mainly from friends (80.8%). The highest proportion (88.2%) of participants thought that persistent enlargement of liver and spleen (enlargement of the abdomen) was the main symptom of VL. Of all participants, only 52.1% knew sand fly as the vector of the disease. The overall assessment of participants indicated that 21.1% were knowledgeable, 53.6% had positive attitudes and 14.9% had optimal practices on VL. In conclusion, the survey indicated that participants had better attitude about VL. However, there were a large gap in knowledge and practices. The misunderstanding and incorrect practices may remain serious concerns in the control and prevention of the disease. It is recommended that health education program should be strengthened to increase peoples' awareness and improve their practices on VL in the district and further studies are strongly suggested for better understanding of the dynamics of the disease in the area. © 2020 The Author(s).
