Evaluation of neurotoxic effect of synthetic pyrethroids: comparative characteristics of neurotoxic action of cypermethrin and zeta-cypermethrin in pre- and postnatal period
Authors: Rashkivska I.O.
Published: November 2019

Synthetic pyrethroids (SPs) are insecticides used in everyday life, in rural and forestry farms. The wide use of SPs is due to their ability to rapidly biodegradate, relatively low toxicity to mammals and high insecticidal activity. Due to the similarity of neurochemical processes, these compounds may also exhibit their neurotoxic properties in non-target objects, in addition to the effects on pests. An overview ofscientific literature has shown that the best biological model for investigating the potential neurotoxic effects of SPs and extrapolation of obtained experimental data to humans is the rat.
Objective — to investigate the effect of cypermethrin and zeta-cypermethrin in pre- and postnatal development; to conduct a comparative study of the neurotoxic properties of cypermethrin and zeta-cypermethrin.
Methods —the article presents the data of two conducted experiments studying the neurotoxic activity of representatives ofpyrethroid insecticides — cypermethrin and zeta-cypermethrin.
Results — it was found that cypermethrin and zeta-cypermethrin exhibit gender-related sensitivity: young male rats were more susceptible to cypermethrin and zeta-cypermethrin compared to females. The effect of cypermethrin and zeta-cypermethrin in the pre-and postnatal period is dose-dependent. Effect of cypermethrin in doses of 17,5 and 35 mg/kg and zeta-cypermethrin at a dose of 12,5 mg/kg in the pre- and postnatal period does not cause a neurotoxic effect in offspring. Cypermethrin exposure at a dose of 70 mg/ kg and zeta-cypermethrin exposure in doses of 35 and 70 mg/kg causes changes in behavioural reactions of offspring of both genders. Administration of cypermethrin at a dose of 70 mg/kg in the- pre and postnatal period affects motor activity and cognitive activity of young male rats (in terms of increasing the latent period of the first movement and decreasing the number of crossed squares). Administration of zeta-cypermethrin at a dose of 70 mg/kg causes in the offspring of both genders disorders in the psycho-emotional state (decrease in the parameters of the grooming), inhibition of motor and cognitive activity (decrease of the number of crossed squares and pointing for males, decrease of the number of crossed squares for females), and reduction of adaptive properties (increase of latent period of the first movement for males). Under the action of zeta-cypermethrin at a dose of 35 mg/kg in males, an increase in anxiety was observed (decrease in the total duration of the grooming). Zeta-cypermethrin showed a greater neurotoxicity on offspring compared with cypermethrin.
Key words: pesticides, synthetic pyrethroids, cypermethrin, zeta-cypermethrin, nervous system, prenatal period, postnatal period, behavioural reactions.

Published: November 2019

The article deals with the problems of students’ healthcare of higher educational establishments. The Law of Ukraine «On Education», «The National Doctrine of the Development of Education in Ukraine», «The Concepts of Children and Youth Education in the National System of Education» emphasize the need to create organizational,
psychological and pedagogical conditions for the personal and physical development and self-development of students, their self-realization in accordance with abilities, social and personal interests, preparation for independent life.
The aim of the research is to find out the state of the students’ health culture formation and the ways to increase the level of health culture in the educational process of higher education.
Pedagogical conditions for the health culture formation include the educational environment, that is the teacher of physical education, and the students’ involvement in sports and mass recreational work outside the classroom.
It is necessary to offer students the opportunity to be engaged in motor activity at a time convenient for them, that is, to combine the directions of physical culture – physical education with mass sports, aimed at providing motor activity of students during their leisure time.
The forms of conducting physical education classes (on a student’s choice) can be fitness classes, cheerleading, table tennis, badminton, power fitness, volleyball, football, aerobics, sports dances, etc. It is understandable that such forms of conducting classes require financial support to the higher educational establishments, which financially will not be able to provide themselves with such a wide range of health-motor programs. At the state level, this should be included into the legislative documents and be financially supported.
An analysis of the questionnaire among students is given on the basis of which students choose modern, rather than classical, physical education, including strength fitness, dance fitness, cross-fitness, table tennis, badminton, football, volleyball, basketball; and a new form of conducting classes is a section work in stead of classical
physical education classes.

Authors: Kılıç Fahri
Published: November 2019

Azerbaycan’ın Sovyet Sosyalist Cumhuriyetler Birliği’ne katılmasıyla Latin esasına dayanan alfabe 1922 yılından itibaren Arap alfabesi ile birlikte kullanılmaya başlanmıştır. Azerbaycan’ın Latin Alfabesini uygulamaya başlaması Türkiye’nin alfabe değişikliğine örnek teşkiletmiştir. 1926 I. Bakü Türkoloji Kongresi’nde alınan “Tüm Türkler İçin Latin Alfabesine Geçme” kararı ile Türk devletleri arasında kültürel bağı güçlendirme düşüncesi Türkiye’de Latin alfabesinin kabulünde etkili olmuştur. Bu gelişmenin hemen ardından Türk kamuoyunda da alfabe tartışmaları yeniden canlanmıştır. Azerbaycan ve diğer Orta Asya Türk topluluklarının Latin alfabelerini benimsemeye başlaması Türkçü aydınlar ve Türk Ocağı gibi kuruluşların alfabe değişikliğine destek vermelerine yol açmıştır. Ayrıca Azerbaycanlı aydınlar da dönemin önemli gazete ve dergilerindeki yazılarıyla Türkiye’de alfabe değişikliğini desteklemişlerdir.Azerbaycan’da Arap alfabesinden Latin alfabesine geçilmesi gereği üzerinden yapılan tartışmalar, Türkiye’de de benzer biçimde yaşanmış, alfabe değişikliği yapılmadan toplumun aydınlatılamayacağı, okuma yazma sorununun giderilemeyeceği, Arap alfabesinden Latin alfabesine geçilmesi halinde, diğer Türk halkları ile olan ilişkilerinin daha da güçleneceği ileri sürülmüştür.

Purpose: This study investigated changes in students’ attitudes using 2 validated interprofessional survey instruments—the Collaborative Healthcare Interdisciplinary Relationship Planning (CHIRP) instrument and the Interprofessional Attitudes Scale (IPAS)—before and after didactic and clinical cohorts.Methods: Students from 7 colleges/schools participated in didactic and clinical cohorts during the 2017–2018 year. Didactic cohorts experienced 2 interactive sessions 6 months apart, while clinical cohorts experienced 4 outpatient clinical sessions once monthly. For the baseline and post-cohort assessments, 865 students were randomly assigned to complete either the 14-item CHIRP or the 27-item IPAS. The Pittman test using permutations of linear ranks was used to determine differences in the score distribution between the baseline and post-cohort assessments. Pooled results were compared for the CHIRP total score and the IPAS total and subdomain scores. For each score, 3 comparisons were made simultaneously: overall baseline versus post-didactic cohort, overall baseline versus post-clinical cohort, and post-didactic cohort versus post-clinical cohort. Alpha was adjusted to 0.0167 to account for simultaneous comparisons.Results: The baseline and post-cohort survey response rates were 62.4% and 65.9% for CHIRP and 58.7% and 58.1% for IPAS, respectively. The post-clinical cohort scores for the IPAS subdomain of teamwork, roles, and responsibilities were significantly higher than the baseline and post-didactic cohort scores. No differences were seen for the remaining IPAS subdomain scores or the CHIRP instrument total score.Conclusion: The IPAS instrument may discern changes in student attitudes in the subdomain of teamwork, roles, and responsibilities following short-term clinical experiences involving diverse interprofessional team members.

Published: November 2019

A sample of nominal composition Yb33,3Al66,7 was synthesized from high-purity elements (Yb ≥ 98.9 wt.% and Al ≥ 99.999 wt.%) by arc-melting under a purified argon atmosphere, using Ti as a getter and a tungsten electrode. To achieve high efficiency of the interaction between the components, the sample was melted twice. The ingot was annealed at 500°C in an evacuated quartz ampoule for 720 h and subsequently quenched in cold water. The weight loss during the preparation of the sample was less than 1 % of the total mass, which was 2 g. The chemical composition of the selected crystals was checked with a field-emission scanning electron microscope (FEINovaNanoSEM 230) equipped with an EDS analyzer.

Laue and rotation diffraction patterns of selected single crystals showed cubic symmetry. Integrated intensities measured with graphite-monochromatized Мо Kα radiation (l = 0.71073 Å) on an Xcalibur Atlas CCD diffractometer confirmed the cubic lattice. The structure type MgCu2 was assigned and the structure was refined using the program SHELXL (full-matrix least-squares refinement on F2)] with anisotropic displacement parameters for all of the atoms: Pearson symbol cF24, space group Fd-3m, a = 7.7011(4) Å, V = 456.73(7) Å3, Z = 8, R = 0.0261, Rw = 0.0726 for 42 reflections.

It is well-known that the trivalent state is usual one for the rare earth metals. The dependence of the mean atomic volume of the RAl2 binary showed of the so-called “valence” fluctuation state for Eu and Yb.

Published: November 2019

The organic-inorganic perovskite films CH3N-H3PbI3 were synthesized from solutions with different ratios of initial reagents (PbI2 to CH3NH3I were taken in the ratio 1:1, 1:2 and 1:3). To deposit films of organic-inorganic perovskite, solutions with different ratio of initial reagents were applied to the substrates by the spin-coating method. The organic-inorganic perovskites synthesized were of one chemical composition in spite of the fact that different chemical reactions proceeded during the synthesis. It was found that the formation of perovskite occurs according to different schemes depending on the ra-tio of PbI2 and CH3NH3I: without the formation of intermediate compounds (at ratio 1:1) and with the formation of one (CH3NH3)2PbI4 (1:2) and two intermediate compounds (CH3NH3)3PbI5, (CH3NH3)2PbI4 (1:3).It was established that regardless of the ratio of the initial reagents, organic-inorganic perovskites with different morphology are formed. At the ratio of the initial reagents 1:1, needle particles formed, and at the ratio of 1:2 and 1:3, particles have the form of a maple leaf and round shape, respectively.To improve the film stability, polyvinyl butyral polymer was used. It is an amorphous colorless pol-ymer which is characterized by high optical properties, environmental (in particular, H2O, O2 and O3) and light resistance. The stability of films of organic-inorganic perovskite without and with a polymer were investigated by XRD, fluorescence spectroscopy and non-contact optical methods. The stability of the films was evaluated by the content of the additional phase of PbI2, which is formed due to the degradation of the organic-inorganic perovskite film CH3NH3PbI3. It was established that the presence of a polymer layer results in improved stability of samples and decrease the rate of surface recombination velocity compared to samples without a polymer layer.The diffusion length of minority charge carriers of the organic-inorganic perovskite films with the polymeric layer was estimated by the method of spectral dependences of the surface photovoltage. The spectra of surface photovoltage and the diffusion length of minority charge carriers of organic-inorganic perovskites with a polymer layer were compared with the literature data for samples without a polymer layer. This comparison shown that the characteristics of the samples with polymer layer are somewhat worse. It is determined that the organic-inorganic perovskite with the polymer layer is characterized by a smaller diffusion length (by 10%) of the minority charge carriers. The prepared perovskite films CH3NH3PbI3 are promising for the development of effective solar cells.

Chen and Flum showed that any FPT-approximation of the k-Clique problem is not in para- AC 0 and the k-DominatingSet (k-DomSet) problem could not be computed by para- AC 0 circuits. It is natural to ask whether the f ( k ) -approximation of the k-DomSet problem is in para- AC 0 for some computable function f. Very recently it was proved that assuming W [ 1 ] ≠ FPT , the k-DomSet problem cannot be f ( k ) -approximated by FPT algorithms for any computable function f by S., Laekhanukit and Manurangsi and Lin, seperately. We observe that the constructions used in Lin’s work can be carried out using constant-depth circuits, and thus we prove that para- AC 0 circuits could not approximate this problem with ratio f ( k ) for any computable function f. Moreover, under the hypothesis that the 3-CNF-SAT problem cannot be computed by constant-depth circuits of size 2 ε n for some ε > 0 , we show that constant-depth circuits of size n o ( k ) cannot distinguish graphs whose dominating numbers are either ≤k or > log n 3 log log n 1 / k . However, we find that the hypothesis may be hard to settle by showing that it implies NP ⊈ NC 1 .

Abiotic stresses arising from climate change negates crop growth and yield, leading to food insecurity. Drought causes oxidative stress on plants, arising from excessive production of reactive oxygen species (ROS) due to inadequate CO2, which disrupts the photosynthetic machinery of plants. The use of conventional methods for the development of drought-tolerant crops is time-consuming, and the full adoption of modern biotechnology for crop enhancement is still regarded with prudence. Plant growth-promoting rhizobacteria (PGPR) could be used as an inexpensive and environmentally friendly approach for enhancing crop growth under environmental stress. The various direct and indirect mechanisms used for plant growth enhancement by PGPR were discussed. Synthesis of 1-aminocyclopropane−1-carboxylate (ACC) deaminase enhances plant nutrient uptake by breaking down plant ACC, thereby preventing ethylene accumulation, and enable plants to tolerate water stress. The exopolysaccharides produced also improves the ability of the soil to withhold water. PGPR enhances osmolyte production, which is effective in reducing the detrimental effects of ROS. Multifaceted PGPRs are potential candidates for biofertilizer production to lessen the detrimental effects of drought stress on crops cultivated in arid regions. This review proffered ways of augmenting their efficacy as bio-inoculants under field conditions and highlighted future prospects for sustainable agricultural productivity.
The Wily and Courageous Red Fox: Behavioural Analysis of a Mesopredator at Resource Points Shared by an Apex Predator

Published: November 2019

The red fox (Vulpes vulpes) is a widespread and ecologically significant terrestrial mesopredator, that has expanded its range with human globalisation. Despite this, we know relatively little about their behaviour under the wide range of ecological conditions they experience, particularly how they navigate the risk of encounters with apex predators. We conducted the first ethological study of foxes outside their historic native range, in Australia, where both the foxes and their main predator were protected from human hunting. Using remote camera traps, we recorded foxes visiting key resource points regularly utilised by territorial dingoes (Canis dingo), their local apex predator, in the Painted Desert, South Australia. We constructed an ethogram sensitive to a range of behaviours and attitudes. Since foxes are suppressed by dingoes, we expected that the foxes would primarily be in a cautious state. In contrast, we found that foxes were in a confident state most of the time. Where human hunting is absent, social stability of predators may increase predictability and therefore decrease fear.

The use of carbon dioxide (CO2) for stunning and killing animals is considered to compromise welfare due to air hunger, anxiety, fear, and pain. Despite decades of research, no alternatives have so far been found that provide a safe and reliable way to induce unconsciousness in groups of animals, and also cause less distress than CO2. Here, we revisit the current and historical literature to identify key research questions that may lead to the identification and implementation of more humane alternatives to induce unconsciousness in mice, rats, poultry, and pigs. In addition to the evaluation of novel methods and agents, we identify the need to standardise the terminology and behavioural assays within the field. We further reason that more accurate measurements of consciousness state are needed and serve as a central component in the assessment of suffering. Therefore, we propose a roadmap toward improving animal welfare during end-of-life procedures.

Establishing trends in endangered fauna against management efforts is a key but often challenging enterprise. Camera-traps offer a new and literal window into monitoring many different mammalian species. Getting it right demands seeking baseline information about how often target species interact with these devices, prior to setting a long-term monitoring strategy. We used a camera-trap array to collect detection data on three species of threatened ground-dwelling marsupials in south-eastern mainland Australia. Over a four-year period, occupancy estimates for two species of bandicoot (southern brown bandicoot Isoodon obesulus and long-nosed bandicoot Perameles nasuta) and a single species of rat-kangaroo (long-nosed potoroo Potorous tridatylus) were generated. These estimates were variously robust depending on visitation history, but nevertheless indicated persistence of these rare and otherwise under threat species. Detection probability for each species differed between study areas, type of management and with complexity of ground and shrub vegetation cover. The relationship between detection and vegetation structure dictated that survey effort was only robust where conditions were optimal for a given species. Outside of that further survey effort would be required to have confidence in survey outcome. In the future this would demand a different sampling strategy, be that through lengthening survey time or adding additional camera units at sites.
Physiological and Behavioral Indicators to Measure Crustacean Welfare

This project determined how neural circuits are affected during warming by examining sensory neurons, the neuromuscular junction, and the cardiac function and behavior of the commercially important crustacean species, the red swamp crayfish (Procambarus clarkii). Rapid inactivation of neural function in crustaceans prior to slaughter is important to limit exposure to noxious stimuli, thus improving animal welfare. This study demonstrated that as a crayfish is warmed at 1 °C/min, the heart beat stops at 44 °C. When temperature is rapidly increased, at 44 °C synaptic transmission at the neuromuscular junction ceases and primary sensory neurons stop functioning. Even though animals do not respond to stimuli after being warmed to 44 °C, if sensory neurons are returned to 20 °C saline after two minutes, they may regain function. Conversely, the neuromuscular junction does not regain function after two minutes in 44 °C saline. Examining behavior and heart rate while warming at 1 °C/min, 12 °C/min, or 46 °C/min to 80 °C indicated that at approximately 40 °C the heart rate is altered. Within 10 s at 80 °C, the heart stops with the highest heating rate. Directly placing crayfish in boiling water stopped the heart quickest, within 10 s, which likely represents denaturing of the tissue by heat. Using an impedance measure to detect a heartbeat may also be influenced by movements in the denaturing process of the tissue. A rapid increase in the temperature of the crayfish above 44 °C is key to limit its exposure to noxious stimuli.

The objectives of this study were: (i) To investigate possible geographical or environmental factors influencing the infections by Toxoplasma gondii and Neospora caninum in sheep and goats in northern Italy; (ii) to identify areas at risk of infection to set up preventive measures. Forty-three sheep and goat farms were included. Their locations were plotted and associated with T. gondii and N. caninum seroprevalence, then the distribution of farms’ prevalence was evaluated by spatial analysis. Significant clusters for both low and high prevalence were obtained, and a generalized linear model with ordinal logistic regression was implemented to verify if spatial clustering could be due to climate factors (temperature, rainfall, and their interaction). Clusters of high (80.0%) and low prevalence (28.12%) resulted for T. gondii seroprevalence in sheep farms. No significant clusters resulted for goat farms. Clusters of high (38.68%) and low prevalence (21.23%) resulted for N. caninum seroprevalence in sheep farms. One high-prevalence cluster (15.62%) resulted for goat farms. For goats, spatial analysis and analysis on climatic data showed the absence of environmental significant risk factors associated with T. gondii or N. caninum infection. On the contrary, for sheep, annual temperature, rainfall, and their association affected the risk of T. gondii and N. caninum infection. Particularly, high temperatures and abundant rainfalls were related to T. gondii seroprevalence, while low temperatures and scarce rainfalls were related to N. caninum seroprevalence.

In recent years, tremendous efforts have been made in the engineering of bispecific or multi-specific antibody-based therapeutics by combining two or more functional antigen-recognizing elements into a single construct. However, to the best of our knowledge there has been no reported cases of effective antiviral antibody-peptide bispecific fusion proteins. We previously developed potent fully human monoclonal antibodies and inhibitory peptides against Middle East Respiratory Syndrome Coronavirus (MERS-CoV), a novel coronavirus that causes severe acute respiratory illness with high mortality. Here, we describe the generation of antibody-peptide bispecific fusion proteins, each of which contains an anti-MERS-CoV single-chain antibody m336 (or normal human IgG1 CH3 domain as a control) linked with, or without, a MERS-CoV fusion inhibitory peptide HR2P. We found that one of these fusion proteins, designated as m336 diabody-pep, exhibited more potent inhibitory activity than the antibody or the peptide alone against pseudotyped MERS-CoV infection and MERS-CoV S protein-mediated cell-cell fusion, suggesting its potential to be developed as an effective bispecific immunotherapeutic for clinical use.
