Olive leaves extract mediated zero-valent iron nanoparticles: synthesis, characterization, and assessment as adsorbent for nickel (II) ions in aqueous medium

Abstract Zero-valent iron nanoparticles (NZVI-NPs) possess significantly high surface area and volume ratio, and this unique surface characteristic has enhanced reactivity to their adsorption potential. In this work, a bio-matter (Olive leaves extract) is deployed as a nature-inspired reducing agent for the synthesis of NZVI-NPs. The particle size of NZVI-NPs has been determined using particle sizer. The NZVI-NPs are characterized using analytical and morphological techniques such as ultraviolet − visible spectroscopy (UV − vis), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction spectroscopy (XRD), scanning electron microscope (SEM), Brunauer–Emmett–Teller (BET), and Fourier transform infrared (FTIR) spectroscopy. The average crystalline size of NZVI-NPs are around 30–60 nm while maximum adsorption is at 225 nm. XRD spectrum shows two distinctive diffraction peaks at 25.40° and 42.50° corresponding to lattice plane value indexed at (200) and (222) planes of faced centered cubic (FCC). At optimized experimental conditions, NZVI-NPs show 97% removal efficiency of Ni+2 ions from aqueous solution. The equilibrium time has been found to be 55 min and the monolayer maximum adsorption capacity is 139.5 mg/g. Kinetically, Ni+2 ions adsorption has been modelled using various physical isotherms and the data best fitted Freundlich isotherm model and pseudo-first-order kinetic; revealing a maximum adsorption capacity of 139.5 mg/g at 25 ± 3 °C and pH of 6.5. Desorption tests affirm the possibility of recovering reasonable amount of NZVI-NPs after used. The specific surface area of the NZVI-NPs sample measured by BET analysis is 21.9967 m2/g indicating a high adsorption capacity. Graphical Abstract
PERCEPÇÕES DE ESTUDANTES SOBRE A INTERNACIONALIZAÇÃO UNIVERSITÁRIA NO BRASIL – PONTOS DE VISTA LOCAIS PERCEPCIONES DE ESTUDIANTES SOBRE LA INTERNACIONALIZACIÓN UNIVERSITARIA EN BRASIL – PUNTOS DE VISTA LOCALES

This study aims to reflect on the relationship between internationalization and foreign languages (L2) as perceived by learners of a language and internationalization program, funded by the Brazilian government at a federal university. The discussion addresses the role of national/local language policies, relating them to the internationalization of higher education in Brazil. Answers to an online questionnaire used here suggest that the idea of internationalization is associated mainly with academic mobility. The importance of learning L2 for internationalization was also highlighted in the data. Problems such as the low number of language courses offered outside the main campus and the low language proficiency of lecturers at the university were also mentioned.

Effects of duration and conditions of storage on germination of seeds of Pedicularis sceptrum-carolinum (Orobanchaceae)

Choosing optimum conditions for plants of the Pedicularis genus to productively germinate and undergo the initial stages of development is currently a relevant problem in the search of solutions to successfully grow these taxa. For the experiments, seeds of Pedicularis sceptrum-carolinum L. (Lamiales, Orobanchaceae) were collected in the first decade of September in the vicinity of Chashnitskoe Lake. The study of specifics of germination of seeds and the initial stages of the development of P. sceptrum-carolinum was carried out in controlled laboratory conditions in a climate chamber with illumination (1,200–1,500 lux, photoperiod of 9/15, temperature of 23–25 °С). After a month-long storage of seeds in their fruit capsules in the laboratory conditions, the greatest germination (83.3–93.3%) was achieved after their subsequent dry maintenance (taken out of the fruits) in a refrigerator at the temperature of +2. +3 oС for 3 or 6 months. Lower values of final germination were obtained after maintaining dry seeds at the temperature of –24. –28 oС for 3 months. Increasing periods of such storage up to six months led to decrease in the final germination and energy of germination. After-ripening lasting different periods provided lower values of the two most important parameters – final germination and energy of germination, even in cases of quite long periods of dry storage in the laboratory. The initial stages of the development of plants from seeds of P. sceptrumcarolinum, which had undergone 3-month stratification in a refrigerator, were studied during the period of 2.0 (2.5) months in different conditions: Petri dishes on moistened filter paper, and in glass vessels with settled tap water, in soil in a plastic container (pure groups of sowed seeds) and also in soil sown together with seeds of Avena sativa L. , with seeds put singly into a plastic block of 9 cassettes. The study revealed morphological differences in plants that had developed over the two-months growth, in each variant of the experiment. We recorded fragmentary development of haustorial hairs on the lateral roots of the plants in the pure sown group and also the haustorium in the group sown together with common oat. We achieved no further development and the plants died. The plants grew for a longer period (2.5 months) in the pure sown groups, which then died as well. The study we performed may be a basis for preparing successful introduction and cultivation of P. sceptrum-carolinum, which would be an important source of preservation of a species that raises concerns on account of the rapid decreases in its populations, narrowing of its range and rare occurrence.
Outcomes and analysis of fetomaternal elements and delivery strategies with neonatal respiratory distress

Birth asphyxia continues to be the leading cause of perinatal mortality and developmental and neurological handicaps in both term and preterm infants. The occurrence of birth asphyxia is closely related to a number of maternal, fetal and obstetrical risk factors. Reduction in the incidence of asphyxia at birth requires identification of high risk factors, to envisage an appropriate and timely action in such cases. The present study attempts to find out the importance of selected maternal factor and fetal factors and mode of delivery on the incidence of neonatal asphyxia. About one-fourth of all neonatal deaths are caused by perinatal asphyxia in worldwide. Birth asphyxia is responsible for 23% perinatal deaths in low-income countries. This finding signifies that perinatal asphyxia is still a global burden. During perinatal asphyxia, as a result of primary energy failure (deprivation from high-energy reserves of phosphate), cell damage can take the form of cell necrosis, commonly referred to as primary cell death. The extent of the damage depends heavily on the length and the intensity of the ischemia-hypoxia. Moreover, cell damage can occur in another form. In other words, on recovery through resuscitation, progressive cerebral edema, excitatory amino-acid accumulation at cellular ABSTRACT
Sex chromosome diversification in the smooth snake Coronella austriaca (Reptilia, Serpentes)

The smooth snake Coronella austriaca is a widespread Palearctic colubrid species. The species has been the subject of several molecular and phylogeographic studies which highlighted the occurrence of distinct genetic lineages in different areas of the species distribution, but scarce cytogenetic data are currently available on the species. In this paper we present a molecular and karyological study performed with several banding, staining methods and NORFISH on samples of C. austriaca from different geographical areas (Italy and Greece) of the species distribution. The molecular and phylogenetic analysis unambiguously placed the studied samples in different clades with a clear geographical pattern. The karyotype of the two female samples studied was composed of 2n = 36 chromosomes with 16 macroand 20 microchromosomes and a mix of plesiomorphic and derivate chromosome features. All macrochromosomes were biarmed with the exception of pair 5 that was telocentric. NORs were detected on a microchromosome pair. In both females, the pair 4 was heteromorphic (and completely heterochromatic after C-banding in the Italian female), representing the first report of a ZZ/ZW sex chromosome system with female heterogamety in C. austriaca. In addition, the W chromosome showed a different morphology between the two female studied (submetacentric and subtelocentric), highlighting the occurrence of a chromosomal diversification among distinct geographical areas of the species distribution and further supporting that the species contains different diverging evolutionary clades.
Existing Risks of Forest Fires in Radiation Contaminated Areas: A Critical Review

The purpose to highlight and focus on the most important risks of forest fires in radiationcontaminated areas, with some detailing of the problem in the Chernobyl Exclusion Zone (CEZ). The search strategy was to collect a sufficient number of relevant publications in ScienceDirect, PubMed, Mendeley, ResearchGate, GoogleScholar from 2006 to the present in English, Russian, Ukrainian. Requests were made on the topics "Forest fires in a radioactively contaminated area" and "Assessing the territories' radiation safety", as well as for the keywords of this study. Analysis of available open information about the CEZ was done. Although, in the future, temperatures are expected to rise in contaminated forests, and the amount of precipitation will remain the same or slightly decrease, which will contribute to an increase in the frequency of fires. Considering the socio-economic situation in Ukraine, the introduction of early detection systems is more profitable than the elimination of the consequences of such emergencies. Investigations have been studied, which were published after 2006 only in English, Russian, and Ukrainian. The most attention is paid to Chernobyl Exclusion Zone. Despite the fact that a lot of studies are devoted to the study of the ecological situation in radioactively contaminated areas, many issues related to safety still concern the population living in this area. The reason for this is intermittent fires, which again and again cover large areas with smoke and cannot be extinguished for a long time. To eliminate anxiety, it is necessary to convey truthful information to the population in the most accessible and convincing way. It was a critical look at numerous studies in this area that made it possible to present concentrated information understandable for most segments of the population. The document concentrates on the most key problems of fires in radioactive forests, shows the intensity of the radionuclides impact on the population and the exposure ways, as well as the probable risks. Such information is necessary to reduce the psychological stress that can be caused by the media influence. Objectively understood situation promotes constructive action in extreme conditions and reduces the likelihood of panic.
Nutritional composition and FT-IR functional group analysis of pharaoh cuttlefish (Sepia pharaonis) from Puducherry coastal waters, India

The nutritional composition and functional groups of the edible portion of the most often utilized cuttlefish, Sepia pharaonis of Puducherry coastal waters, India was evaluated. Moisture is the basic component of the mantle with 82.45±0.15% followed by a good source of 14.5±0.1% protein. The ash, lipid, and carbohydrates were found less than 1%. The energetic value of the mantle of cuttlefish S. pharaonis is calculated as 6.06 KJ/g. Na and K were found in considerable quantities of 2772 and 3247 mg/kg respectively and the Na/K ratio (0.85) was less than 1. The amount of Zn, Mn, B, Al, Sr, and As was found to be relatively high when compared to a low or insignificant level of Cu, Mo, Se, Cr, Ni, Pb, and Hg. The fatty acid profile analysis revealed that it contains 71.67% saturated fatty acids,17.87% polyunsaturated fatty acids and 10.38% monounsaturated fatty acids. In all three types, the C16:0 palmitic acid (40.29%), C18:0 stearic acid (16.54%), and C22:6 docosahexaenoic acid (13.52%) represented as the dominant fatty acids. The FT-IR analysis disclosed the presence of various functional groups belonging to protein, lipids, and polysaccharides. Thus, the present study proved that the cuttlefish S. pharaonis is considered as a potential nutraceutical and the right choice of food for greater and wider human consumption.
GENETIC PARAMETERS FOR SOME REPRODUCTIVE TRAITS IN EGYPTIAN BUFFALOES

The traits of the study were: age at first calving (AFC), gestation length (GL), days open (DO), and calving interval (CI). The records were collated from three buffalo experimental herds (El-Nattaf El-Gadid, El-Nattaf El-Kadim and El-Gimeza) that belonging to Animal Production Research Institute, Agricultural Research Center, Ministry of Agriculture and Land Reclamation, Egypt. A total of 19,445 records for 1534 buffalo cows calved from 1991 to 2018 were analyzed. A moderate estimate of repeatability was obtained for GL and CI of 0.38 and 0.15, respectively. While the repeatability estimation was slightly lower at 0.13 for DO. That can be explained by the high obtained values of random permanent effect variance of 73, 955, 1119 for GL, DO and CI, respectively. For all studied traits heritability estimates (h 2 ) were very low as it ranged from 0.0001 to 0.01, this could be due to the small estimated additive effect of 2.0, 0.01and 11.0 for GL, DO and CI, respectively. Except for AFC, h 2 was slightly higher at 0.13. Estimated genetic (rg) and phenotypic (rp) correlation among all traits were in the same trend being positive and varied from low to high (0.04 to 0.99). The highest correlation value either genetic or phenotypic was between CI and DO. While the lowest rg and rp values were between GL and DO.
CMAR_A_316759 6123..6128

*These authors contributed equally to this work Objective: The aim of this study was to quantify the expression of melanoma-antigen family A proteins (MAGE-A) and New York esophageal squamous cell carcinoma-1 (NYESO-1) in breast cancer and establish the prognosis of breast cancer patients with MAGE-A and NY-ESO-1 co-expression. Methods: A total of 122 patients with breast cancer were recruited for this study. Their clinicopathological data were collected retrospectively, and the MAGE-A and NY-ESO-1 expressions in paraffin-embedded specimens from the 122 patients were evaluated using immunohistochemical analysis. In addition, the survival states of the patients were recorded. Results: Fifty-four patients (44.26%) were MAGE-A positive and 46 (37.70%) were NYESO-1 positive. Interestingly, 22 of the 46 NY-ESO-1-positive cases co-expressed MAGE-A. The expression of MAGE-A was positively associated with estrogen-receptor status (χ = 4.026, p = 0.045) and human epidermal growth factor receptor 2 status (χ = 5.482, p = 0.019), while the expression of NY-ESO-1 was positively associated with p53 expression (χ = 4.541, p = 0.033). Of the 122 patients, the lowest survival rate was observed in patients with NY-ESO-1 (+)/MAGE-A (+), with a 5-year survival rate of 59.09% and a median survival of 97 months. Conclusion: The results showed that MAGE-A and NY-ESO-1 were frequently expressed in breast cancer patients. The co-expression of MAGE-A and NY-ESO-1 occurred in about 18% of these patients, and it may indicate a poor prognosis.

Effects of exogenous NO on antioxidant system of Taxus plants under simulated acid rain stress

Taxus is a famous medicinal and landscape tree species. The aim of this study was to explore the effect of exogenous nitric oxide (NO) on the resistance of Taxus plants to acid rain stress and to identify Taxus species with strong acid rain resistance by principal component analysis and comprehensive evaluation. In this study, sodium nitroprusside (SNP) was used as the exogenous NO donor. The effects of different SNP solution concentrations on the antioxidant systems of three Taxus species subjected to simulated acid rain stress (pH = 3.0) were compared. In order to achieve this goal, we determined the rate of O production, the ASA and GSH contents in leaves of three Taxus plants (Taxus mairei, Taxus chinensis, and Taxus yunnanensis). At the same time, the active leaves of some antioxidant enzymes (SOD, POD, CAT, APX and GR) were determined. For Taxus chinensis plants subjected to acid rain stress, treatment with an SNP concentration of 0.25 mmol·L led to the most significant improvements in the antioxidant system. For Taxus mairei and Taxus yunnanensis, the treatment with the SNP concentration of 0.50 mmol·L was best for improving their antioxidant systems under stress. Meanwhile, Taxus chinensis had the strongest resistance to simulated acid rain, followed by Taxus mairei and Taxus yunnanensis.
Technology Integration of the In-Service EFL Teachers: A Study at a Teacher Profession Education Program

Utilizing technology in the classroom characterizes the 21 century teachers. Therefore, teachers are demanded to be able to use technology in pedagogical practices in order to fulfill their students’ needs facing rapidly digitalized life. This study was designed to investigate the perceptions of a group of in-service English as Foreign Language (EFL) teachers who studied at a Teacher Profession Education program at a state university, concerning the application of technology within challenges they faced during their study. This study used qualitative research with narrative approach as a strategy of inquiry. The data were obtained by using a semi-structure interview with the in-service teachers and documentation. The data were analyzed using thematic analysis. The results of the study showed that the participants generally perceived positively the technology integration taught by their university instructors during their study time at the Teacher Profession Education program although there was a negative response when they were firstly introduced with the technology. It might have been caused by their lack of technological Fatimah Tuzahra, et al 318 Indonesian Journal of EFL and Linguistics, 6(1), 2021 knowledge. The result also revealed that the participants found it challenging when it came to the use of novel technology as introduced and applied by their university instructors. In addition, their own integration of technology during their Teaching Practice was a challenge due to the students’ low motivation to engage in the online learning activity which was the mode of learning. The findings of this study suggest that teachers need to advance their skills and knowledge to utilize technology in supporting their pedagogical practices.
Ameliorative effect of Ethanol Extract of Annona Muricata Leaves in Sodium Arsenite Induced- Toxicity in Male Wistar Rats

Ingestion of arsenic, a known contaminant in drinking water causes cancer at multiple tissues and there is no cure. Consumption of arsenic contaminated water has been implicated metalloid-induced carcinogenesis. Research is therefore directed at chemoprevention using medicinal herbs for the management of arsenicosis. In this study hepatoprotective activity of ethanolic extract of Annona muricata (AM) leaves was assessed against sodium arsenite (SA) induced hepatic injury in albino rats. The animals were pre-treated with either 250 or 500mg/kg body weight of rat before exposure to SA. SA was dissolved in distilled water and administered at a dose of 5 mg/kg body weight on the 7 th , 14 th and 21 st day of the experiment. SA was observed to induce a significant increase (p < 0.05) in serum aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase activities (ALP). However, pretreatments of rats with various doses of AM significantly (P<0.005) reduced serum enzyme levels to near normal against SA treated rats. Furthermore, Original Research Article Adegboyega et al.; IJBCRR, 30(2): 8-15, 2021; Article no.IJBCRR. 66966 9 histopathological observations revealed that treatment with AM extract protected the animals from SA induced liver damage. The results indicated that the leaves of Annona muricata possess hepatoprotective activity on SA induced hepatic injury in rats.
