Interaction of nistranol with estradiol and progesterone receptors in the rat uterus cytosol in vitro and in vivo
Authors: Kareva Ye. N. , Fedotov V. P. , Rzheznikov V. M. , Solovyova Ye. V. , Pokrovskaya Ye. V.
Published: October 2019

Interactions between nistranol and estradiol and progesterone receptors in the cytosol fraction of the uterine tissue of oophorectomized rats and the relative competitive capacity of nistranol have been studied 24 h after a single injection of the drug. The results demonstrate the effects of nistranol on estradiol and progesterone binding. Nistranol boosting of uterine growth in rats is explained by its capacity to accelerate the translocation of hor- mone-receptor complexes into the nucleus. Investigations of the capacity of new estrogens to compete with estradiol for binding in the tissues of target organs in vitro and affect estradiol and progesterone binding in vivo permit a more effective screening of estrogens than use of only the classical in vitro method.
V. N. Babichev. Neuroendocrine Regulation of the Reproductive System
Authors: Goncharov N. P.
Published: October 2019

The problems raised by V. N. Babichev in this monograph on deciphering the central mechanisms of regulation of the pituitary gonadotropic function occupy one of the main places among other issues of neuroendocrinology. To study the sequence of events in neuroendocrine processes that contribute to the preovulatory release of luteinizing hormone is a very complicated but necessary task. In the last decade, neuroendocrinologists are no longer satisfied with a fairly well-studied system of the relationship between gonadaliberin - gonadotropins and sex steroids. The essential role of monoamines of central origin in the regulation of the synthesis and secretion of pituitary gonadotropins, which show their function through luliberins, is shown. Experimenters and clinicians now have rich material that deepens and significantly changes our understanding of the neuroendocrine control of the reproductive system. These literature data in combination with prof. V.N. Babicheva demanded their generalization, which was perfectly done in the peer-reviewed monograph. A comprehensive approach to the study of the entire reproductive function control system, carried out in the laboratory of physiology of the endocrine system of the Russian Academy of Medical Sciences, starting from the period of early ontogenesis, made it possible to specify the role of neurotransmitters such as norepinephrine, dopamine and serotonin in the regulation of the pituitary gonadotropic function, to determine the point of their application in the hypothalamus , the direction of the response from gonadotropins depending on the level of sex hormones in the blood. The starting role of norepinephrine in the mechanism of ovulatory release of gonadotropins has been established, while the main point of its application is the preoptic region. The main point of application of dopamine is the area of ​​the mediobasal hypothalamus, or rather, the arcuate core.
Brasil-China: uma integração produtiva virtuosa?
Authors: Silva Mortari Valéria , Giusti de Araújo Caroline , Diegues Antônio Carlos
Published: October 2019

Este artigo objetiva analisar os benefícios bilaterais gerados na relação comercial entre Brasil e China. Entende-se que as transformações estruturais vivenciadas nas últimas décadas são fatores condicionantes dos resultados. O método utilizado foi a análise insumo-produto pelo multiplicador inter-regional, que permite mensurar o estimulo direto e indireto gerado pela produção setorial chinesa sobre a produção brasileira (e vice-versa) entre 2000 e 2014. Os resultados mostraram que os estímulos promovidos pela produção brasileira sobre a chinesa são maiores. Dessa forma, entende-se que há uma assimetria no posicionamento das economias em benefício à asiática, dada pela falta de articulação de políticas no Brasil.
Mudança estrutural e seu impacto na produtividade: uma análise da ascensão do setor de serviços na economia brasileira
Authors: Silvestri Cândido Rocha Carolina , Tatsch Ana Lúcia , Ferraz Cário Silvio Antônio
Published: October 2019

Observa-se na realidade de diversos países, desenvolvidos e em desenvolvimento a ocorrência de mudança estrutural em direção à redução da participação da indústria no Produto Interno Bruto (BIP). Tal processo, denominado processo de desindustrialização, impacta a produtividade das economias de maneira diferente. Quando o setor de serviços emergente é capaz de ampliar a complexidade econômica, vê-se uma tendência de aumento de produtividade, no entanto, quando este não se relaciona diretamente ao setor industrial remanescente, ou seja, quando é composto por serviços não estratégicos, observam-se problemas no crescimento da produtividade. Nesse contexto, por meio da utilização de um modelo shift-share, baseado no modelo de decomposição canônica originário de Fabricant (1942), a realidade brasileira foi analisada visando caracterizar a direção da mudança estrutural e compreender sua consequência em termos de produtividade. Como resultado, verifica-se que o crescimento da participação do setor de serviços no emprego relaciona-sesobretudo com um aumento do emprego nos segmentos de serviços financeiros; seguros; serviços imobiliários e comerciais; e serviços comunitários, sociais e pessoais. Conclui-se que tal fenômeno decorre da ausência de dinamismo dos demais setores econômicos e não de medidas que proporcionam mudança estrutural para o aprofundamento da complexidade econômica e o aumento da produtividade.

Skin-to-Skin Contact Activates Oxytocin Release and Correlates to Parent Engagement
Authors: Vittner D. , Butler S. , Smith K. , Makris N. , Samra H. , McGrath J.
Published: October 2019

Over 15 million premature infants are born annually around the world. It has been optimistically yet incorrectly proposed, that healthy preterm infants without major complications eventually catch-up developmentally to term infants. Research shows these preterm infants remain increasingly disadvantaged on many neurodevelopmental outcomes. Parental touch, especially during skin-to-skin contact (SSC) has the potential to reduce the adverse consequences of prematurity. SSC is an evidenced based strategy that increases parental proximity and provides an interactive environment known to enhance infant physiologic stability and aﬀective closeness between parent and infant. Evidence suggests SSC activates oxytocin release in mothers, fathers and infants.

Abordagem das bactérias extremófilas em livros didáticos de biologia do ensino médio
Authors: Santos Clarice Regina da Silva , Braga Héberly Fernandes
Published: October 2019

Os livros didáticos são os instrumentos de ensino mais acessíveis aos professores nas escolas, sendo primordial que os conteúdos possam ser contemplados da forma mais ampla possível. O tema arqueas, merece ser pontuado nesses materiais, especialmente pelos recentes avanços tecnológicos que possibilitam o emprego de tais micro-organismos em diversas áreas. Neste sentido, foram analisadas oito obras didáticas de Biologia do Ensino Médio segundo os aspectos gerais de Coerência e Conceitos, Quantificação e Interdisciplinaridade e Contextualização das bactérias extremófilas, tendo por base o guia do Programa Nacional do Livro Didático do Ministério da Educação. Os critérios “aplicações biotecnológicas e adaptações bioquímicas” foram os que apresentam as maiores defasagens em relação à abordagem do assunto, na maioria das obras didáticas. No geral, somente uma obra teve boa avaliação em todos os aspectos analisados. Quanto ao critério “coerência entre fundamentação teórica e, imagens, textos e exercícios propostos”, todas as obras apresentaram-se satisfatórias. Portanto, apesar de as discussões sobre esse tema serem de suma importância ao contexto atual, as obras apresentam deficiências técnicas, em especial no que tange às aplicações biotecnológicas.

Published: October 2019

O Brasil possui diversidade biológica e cultural que colabora para que as plantas medicinais sejam utilizadas como uma alternativa ao uso de medicamentos. Por serem naturais e menos onerosas, seu consumo tem aumentado, porém a falta de fiscalização na sua comercialização põe em discussão sua qualidade. Esse trabalho visa analisar a qualidade microbiológica de amostras de Achyrocline satureioides (LAM.) DC., popularmente conhecida por marcela, comercializadas por feirantes em cidades do Rio Grande do Sul (RS) - Brasil. Foram analisadas bactérias mesófilas, fungos, coliformes totais e termotolerantes, Staphylococcus coagulase negativa e positiva e Escherichia coli. Todas as análises seguiram a metodologia descrita no Manual de Métodos de Análise Microbiológica de Alimentos e Água. Os resultados indicam que as amostras estão adequadas para consumo conforme preconiza a legislação Brasileira. A contaminação por bactérias mesófilas aeróbias apresentou variação de 2,6x103 a 1,2x106 UFC e por fungos foi de 1,8x103 a 4,2x104 UFC. Quatro amostras apresentaram contagem para coliformes totais, duas para coliformes termotolerantes e somente em uma amostra foi detectada E. coli. Staphylococcus coagulase positiva não foi detectado. Em vista dos argumentos apresentados conclui-se que a marcela comercializada por feirantes e vendedores ambulantes de cidades do RS não apresenta riscos microbiológicos à população, pois atendem às especificações e critérios compreendidos pela legislação brasileira para microrganismos indicadores de contaminação ambiental e por manipulação.

The effect of concurrent aerobic-resistance training on thyroid hormones, blood glucose hemostasis, and blood lipid indices in overweight girls with hypothyroidism
Authors: Mohammadi Sefat Sahar , Shabani Ramin , Nazari Marzieh
Published: October 2019

Background

The present study aimed to explore the effect of 8 weeks of concurrent aerobic-resistance training on thyroid stimulating hormone (TSH), thyroxine (T4), blood lipid profile, and blood glucose hemostasis in adolescent girls with hypothyroidism.

Materials and methods

In this clinical trial, 20 adolescent girls with hypothyroidism [age: 12.10 ± 1.94 years; body mass index (BMI): 25.25 ± 2.91 kg/m2] were selected and randomly assigned to experimental and control groups. The experimental group was treated with 8 weeks of concurrent aerobic [60–80% heart rate reserve (HHR)] and resistance (40–65% of 1RM) training. Blood was sampled before and after training. Data were analyzed using a pairwise t-test and an independent t-test (α < 0.05).

Results

Within-group comparison revealed significant decline of body index, BMI, fat percentage, fasting blood sugar, and homeostatic model assessment (HOMA) in the experimental group (p = 0.002, p = 0.001, p = 0.001, p = 0.03, and p = 0.02, respectively). Also, inter-group comparisons indicated significant differences in weight, BMI, fat percentage and HOMA (p = 0.001). But, no significant difference was observed in the blood sugar index (p > 0.05).

Conclusion

A short-term period of concurrent aerobic-resistance training may improve blood glucose hemostasis and body composition of adolescent girls with hypothyroidism. However, further research is necessary.

Published: October 2019

Background and aims: Given that computer games have positive and negative functions and may affect the mental health of individuals, the present research aimed to study the relationship between the tendency to playing computer games and the mental health of junior high school students in Shahr-e Kord. Methods: The current cross-sectional descriptive-analytical study was conducted on 245 boy and girl junior high school students of Shahr-e Kord in 2016. The participants were selected using a random cluster sampling method. The required data were collected using questionnaires of demographic variables, the standard 28-item General Health Questionnaire, and an author-made questionnaire on the tendency to computer games. Finally, the data were statistically analyzed using descriptive and analytic tests in SPSS-18. Participation in the study was voluntary. Results: The results showed that 31.8% of the students aged 14 years old. In addition, the tendency to computer games was higher in girls (0.027) and their level of mental health was lower compared to boys (P=0.032). There was a significant relationship between the tendency to computer games and the age of the students (P=0.023). Eventually, age (P=0.025) and gender (P=0.09) represented a significant relationship with the mental health of the students. Conclusion: Based on the low level of mental health in girls, it is necessary to pay special attention to the symptoms of depression and anxiety and social functions in adolescents, control the time spent on playing the computer games, plan carefully for their leisure time, direct adolescents toward reading books, and promote their health using educational patterns.

Authors: Manliura Datilo Philemon , Ismail Zuhaimy , Dare Jayeola
Published: October 2019

Background and aims: Since accurate forecasts help inform decisions for preventive health-care intervention and epidemic control, this goal can only be achieved by making use of appropriate techniques and methodologies. As much as forecast precision is important, methods and model selection procedures are critical to forecast precision. This study aimed at providing an overview of the selection of the right artificial neural network (ANN) methodology for the epidemic forecasts. It is necessary for forecasters to apply the right tools for the epidemic forecasts with high precision. Methods: It involved sampling and survey of epidemic forecasts based on ANN. A comparison of performance using ANN forecast and other methods was reviewed. Hybrids of a neural network with other classical methods or meta-heuristics that improved performance of epidemic forecasts were analysed. Results: Implementing hybrid ANN using data transformation techniques based on improved algorithms, combining forecast models, and using technological platforms enhance the learning and generalization of ANN in forecasting epidemics. Conclusion: The selection of forecasting tool is critical to the precision of epidemic forecast; hence, a working guide for the choice of appropriate tools will help reduce inconsistency and imprecision in forecasting epidemic size in populations. ANN hybrids that combined other algorithms and models, data transformation and technology should be used for an epidemic forecast.

Published: October 2019

Geogrids are used for the rehabilitation of cracked pavements. To ensure an efficient reinforcement, it is required to know the residual mechanical properties of the geogrid after its implementation and compaction of the above asphalt concrete layer and the level of damage of the grid. This article presents the results of the national French project SolDuGri dealing with pavement reinforcement by geogrids and more precisely the reproduction in laboratory of the in situ damage. In this project, full-scale tests have been performed to evaluate the in situ damage of four different types of geogrids in asphalt concrete pavements. Then, after construction, the geogrids have been recovered from different locations on the field sections, where they had been subjected to compaction. These grids have been subjected to direct tension tests in the laboratory. Laboratory analyses like scanned asphalt concrete and greogrid surfaces have been performed to evaluate indenter shapes. Different sets of indenters have been made, and a laboratory complete study of greogrid indentation tests has been performed with different sets of temperature, indenter shapes, and indentation forces. The first conclusions are that the indenter geometry and the temperature have the main influence on the strength resistance and elastic modulus of the grid. Results obtained after indentation performed in laboratory can be compared to those measured on in situ recovered grids.
Synaptic Plasticity at Inhibitory Synapses in the Ventral Tegmental Area Depends upon Stimulation Site
Authors: St. Laurent Robyn , Kauer Julie
Published: October 2019

Drug exposure induces cell and synaptic plasticity within the brain reward pathway that could be a catalyst for progression to addiction. Several cellular adaptations have been described in the ventral tegmental area (VTA), a central component of the reward pathway that is the major source of dopamine release. For example, administration of morphine induces long-term potentiation (LTP) of excitatory synapses on VTA dopamine cells and blocks LTP at inhibitory synapses. Drug-induced synaptic changes have a common endpoint of increasing dopamine cell firing and dopamine release. However, gaining a complete picture of synaptic plasticity in the VTA is hindered by its complex circuitry of efferents and afferents. Most studies of synaptic plasticity in the VTA activated a mixed population of afferents, potentially yielding an incomplete and perhaps misleading view of how drugs of abuse modify VTA synapses. Here, we use midbrain slices from mice and find that electrical stimulation in two different regions induces different forms of plasticity, including two new forms of LTP at inhibitory synapses. High-frequency stimulation (HFS) induces LTP independently of NMDA receptor (NMDAR) activation, and surprisingly, some inhibitory inputs to the VTA also undergo NMDAR-independent LTP after a low-frequency stimulation (LFS) pairing protocol.
Parabrachial Complex: A Hub for Pain and Aversion
Authors: Chiang Michael C. , Bowen Anna , Schier Lindsey A. , Tupone Domenico , Uddin Olivia , Heinricher Mary M.
Published: October 2019

The parabrachial nucleus (PBN) has long been recognized as a sensory relay receiving an array of interoceptive and exteroceptive inputs relevant to taste and ingestive behavior, pain, and multiple aspects of autonomic control, including respiration, blood pressure, water balance, and thermoregulation. Outputs are known to be similarly widespread and complex. How sensory information is handled in PBN and used to inform different outputs to maintain homeostasis and promote survival is only now being elucidated. With a focus on taste and ingestive behaviors, pain, and thermoregulation, this review is intended to provide a context for analysis of PBN circuits involved in aversion and avoidance, and consider how information of various modalities, interoceptive and exteroceptive, is processed within PBN and transmitted to distinct targets to signal challenge, and to engage appropriate behavioral and physiological responses to maintain homeostasis.
Dry after-ripening, light, cold stratification and temperature effects on seed germination of Primula poissonii from Yunnan, China
Authors: Peng Deli , Hu Xiaojian , Sun Hang , Li Zhimin
Published: October 2019

Primula poissonii, an attractive wild plant growing in the subalpine/alpine region of southwest China, has low seed germination in cultivation. This study attempted to improve seed germination by testing the effect of several treatments including dry after-ripening (DAR), light, cold stratification (CS) and temperature gradient treatments. DAR increased germination at 15/5 and 25/15°C, as compared with fresh seeds. DAR seeds germinated significantly better (> 80%) at higher temperatures (20-28°C) than at lower (10°C, < 20%; 15°C, < 30%) and extreme high temperatures (30°C, < 55%; 32°C, 0%). Incubation at alternating temperature (25/15°C) did not significantly improve germination; whereas at 15/5°C germination increased significantly, compared with the corresponding constant temperature (20 and 10°C, respectively). DAR seeds had a strict light requirement at all temperatures. As DAR and CS are sufficient to break seed dormancy, the seeds of P. poissonii appear to have non-deep PD. For non-dormant cold-stratified seeds, the estimated Tb and thermal time (θ50) were 2.3°C and 74.1°Cd, respectively.
A Fair Version of the Chinese Room
Authors: Çağatay Hasan
Published: October 2019

By the Chinese room thought experiment, John Searle (1980) advocates the thesis that it is impossible for computers to think in the same way that human beings do. This article intends firstly to show that the Chinese room does not justify or even test this thesis and secondly to describe exactly how the person in the Chinese room can learn Chinese. Regarding this learning process, Searle ignores the relevance of an individual’s pattern recognition capacity for understanding. To counter Searle’s claim, this paper, via examining a series of thought experiments inspired by the Chinese room, aims to underline the importance of pattern recognition for understanding to emerge.
Does Inner Awareness Always Accompany Outer Awareness During Perception?
Authors: Chaturvedi Madhu Mangal , Ravishankar Sarma A. V.
Published: October 2019

In the present paper, we defend the thesis that outer-world-directed perceptual consciousness is always accompanied by an inner awareness (IAOA). This is contrary to the view that outer-world-directed conscious mental states are not accompanied by an inner awareness, which is held by Gennaro (2008) against Kriegel’s (2009a and 2009b) self-representationalism. We attempt to show why philosophers like Gennaro get it wrong when they deny the IAOA thesis by critically examining his arguments against it and by giving arguments in its favour.
The Everyday as Revolution and Resistance: G. Debord and M. de Certeau
Authors: Milerius Nerijus
Published: October 2019

The paper analyzes the effort to rethink the status of everyday life in the context of consumer society. Two concepts of everyday life are interpreted – Guy Debord’s critique of society of the spectacle, and Michel de Certeau’s concept of everyday life as resistance. As Debord says, the purpose of the critique of the everyday is to recharge the entire system of capitalism. By capturing the radical contrast between the current meager status of everyday life and the potential of the everyday, Debord was convinced that a radical discrimination of everyday life can only be overcome by radical means – the revolution of the everyday. Rejecting the possibility of transforming the entire structure of the society through everyday life, de Certeau focused on the everyday as resistance to the strategic domains of society. Thus, de Certau’s goal is not to transform the entire system, but to maintain the resilient potential of everyday life as a constant opportunity for daily renewal. The paper concludes that it is the attitudes of everyday life such as resistance that have influenced visual and urban studies.
From the Dual Character of Chemistry to Practical Realism and Back Again: Philosophy of Science of Rein Vihalemm
Authors: Müürsepp Peeter , Nurysheva Gulzhikhan , Bekenova Zhumagul , Usenov Galymzhan
Published: October 2019

The focus of the paper is on Rein Vihalemm’s novel approach to science called practical realism. From the perspective of Vihalemm, science is not only theoretical but first and foremost a practical activity. This kind of approach puts chemistry rather than physics into the position of a typical science as chemistry has a dual character resting on both constructive-hypothetico-deductive (ϕ-science) and classifying-historico-descriptive (non-ϕ-science) types of cognition. Chemists deal with finding out the laws of nature like the physicists. However, in addition to this they deal with substances or stuff that is rather an activity typical to natural history. The analysis of the dual character of chemistry brings about the need to analyse philosophically the reasons why physics has held the position of the only science proper so far. The comparative analysis of physics and chemistry at the basis of practical realism suggests that it is chemistry rather than physics that should hold a special position among sciences. Perhaps we should exchange ϕ-science for χ-science.

Published: October 2019

The method of diffusion chamber in the magnetic field making use of a bremsstrahlung beam with a maximum photon energy of 150 MeV is applied to study the 12C(y,3a) and 16O(y,4a) reactions. A resonance identified as the ground state of 8Be nucleus is found in the distribution of events over the energy of the relative motion of two a-particles. The partial cross-sections of the 8Be nucleus formation channels are measured. It is shown that the mechanism of interaction between a y-quantum and a virtual a-particle pair takes place in this case.
Influence of Inhomogeneity on Transformation and Radiation Processes in Plasma with Upper Hybrid Pump
Authors: Panchenko V. G. , Porytsky P. V.
Published: October 2019

On the basis of the kinetic theory of fluctuations, the processes of the longitudinal Langmuir wave transformation into a transverse electromagnetic wave in the turbulent inhomogeneous plasma have been studied. The plasma turbulence is assumed to arise owing to the parametric decay of the upper hybrid pump wave into a daughter wave and electron-drift oscillations. The transformation coefficient under the parametric instability saturation conditions is determined. The intensity of the electromagnetic radiation emission from the plasma is calculated, and its dependence on the plasma and pump wave parameters is found.
Theoretical Analysis of the Intensity of Ultrasound Absorption in Aqueous Alcoholic Solutions
Authors: Stula Yu. M.
Published: October 2019

Ultrasound absorption in aqueous alcoholic solutions has been studied in the vicinity of their singular points. The abnormal ultrasound absorption is assumed to occur due to the formation of unstable nuclei of a new phase. A model for the time evolution of those nuclei is proposed. The model makes it possible to explain the emergence of the resonance ultrasound absorption in the vicinity of the singular point of the 2-propanol solution. The dependences of the absorption intensity on the nucleus parameters, temperature, and ultrasound frequency are analyzed. A contribution of the ultrasound radiation from the nuclei to the effective shear viscosity of the solutions is estimated. The results of theoretical calculations are compared with available experimental data.

Authors: Chukova O. , Nedilko S.
Published: October 2019

The paper reports the investigation of a structure of luminescence spectra of PbWO4 (PWO) crystals. The doping of the samples with rare earth (RE) impurities is used in order to obtain more information about the composition of spectra of the PWO matrix emission and the structure of its luminescence centers. The decomposition of the emission spectra onto individual bands has shown that 5 bands contribute to the total spectra of all the undoped and RE-doped samples at 10 K. The maxima of the obtained bands are 1.95, 2.2, 2.45, 2.7, and 3.0 eV. Effects of the RE-doping and the annealing on relative intensities of these bands are considered. The nature of luminescence and the structure of the centers involved in the excitation and emission processes responsible for each of the separated bands are discussed.

The energy spectrum of electrons in a metal nanowire with a periodically modulated surface has been found in the framework of perturbation theory. To solve the problem, a transition is made into a coordinate system that “smoothes down” the surface oscillations. The influence of the surface modulation amplitude on size-induced oscillations of the Fermi energy in such systems is analyzed. It is shown that an increase of the modulation amplitude leads to a decrease of the Fermi energy in the wire. Specific calculations were made for Au, Cu, and Al wires.

A series of lanthanide coordination compounds with dimethyl-N-trichloroacetylamidophosphate CCl3C(O)N(H)P(O)(OCH3)2 (HL) [HL = CCl3C(O)N(H)P(O)(OCH3)2 is a ligand of the carbacylamidophosphate (CAPh) type], whose compositions are described by the formula [LnL3 · Phen], where Ln = La, Ce, Pr, Nd, Sm, Tb, Dy, Ho, and Er; L is the deprotonized form of HL; and Phen is 1,10-Phenantroline, has been synthesized. Acetonic solutions of HL and complexes synthesized on its basis are studied by means of 1H- and 31P-NMR spectroscopy at room temperature (298 K). Since the chemical shifts of 1H signals have the pseudocontactorigin, the isotropic shifts of 31P signals are managed to be decomposed into the contact and pseudocontact components. It is found that there are two series of complexes in the solution of [LnL3 · Phen] compounds with the same structure of the coordination sphere within each of the series Ln = (Ce, Pr, Nd, Sm) (series L1) and Ln = (Tb, Dy, Ho, Er) (series L2). The values of the constant of superfine interaction for those complexes are calculated: 0.18 MHz (series L1) and 0.13 MHz (series L2).

The effects of magnesium, copper, and zinc substitutions on spinel ferrites have been investigated by the sol-gel technique. Ferrite compositions of Mg0,25xCu0,25xZn(1−0,5x)Fe2O4 (where x = 0.6, 0.7, 0.8 & 0.9) were prepared at a sintering temperature of 1100 ∘C with a presintering at 500 ∘C. X-ray diffraction (XRD), scanning electron microscopy (SEM), and high-precision impedance analysis are used to characterize structural and dielectric properties, as well as the surface topography and morphology of the samples. A single phase, cubic spinel structure, with decreased lattice constant was observed. SEM micrographs revealed a homogeneous microstructure with uniform size distributions. Both the dielectric constant and dielectric loss tangent decrease, as the incident frequency increases up to a certain saturation point. The direct current (dc) resistivity profile shows that the resistivity increases with the temperature up to the Curie point, then it goes to a constant value. The quality factor (Q-factor) increases with the incident frequency. Hence, the high Q-factor will make ferrites highly useful in applications, especially in multilayer chip inductors.

In the present study, we visualised sundew His6-tagged chitinase protein in crude protein extracts of transgenic tobacco plants following protein separation with sodium dodecyl sulfate polyacrylamide gel electrophoresis by detecting chitinase activity as well as the His-tag. A short sequence encoding six histidines was fused downstream of the DNA sequence encoding the last amino acid of the mature protein. Following binary vector construction and plant transformation, a set of 10 transgenic plants was analysed for transgene expression. Except for one, all transgenic plants exhibited the presence of sundew chitinase protein of ~52 kDa, which was different from the calculated molecular weight of ~32 kDa. Clear identification of DrChitHis protein was performed with a Ni2+:NTA complex conjugated to a fluorescent dye and visualized using light laser-based scanner. A subsequent endochitinolytic activity assay using a N-fluorescein-labelled chitin substrate confirmed that the two transgenic lines with the strongest expression of DrChitHis protein had endochitinolytic activity 6.4 and 6.7 times higher than non-transgenic control.

Perylene (PRL), a five- ring nuclear polycyclic aromatic hydrocarbon (PAH) has attracted attention because of its toxic properties. This study aimed to evaluate the efficiency of yeast consortium YC02 to remediate PRL in presence of ZnO nanoparticles and produced biosurfactant in the growth medium. Response surface methodology (RSM), 3- level five variables Box-Behnken design (BBD) was employed to optimize the factors viz. pH 7.0, temperature 30ºC, shaking speed 130 rpm, inoculum dosage 3% and zinc oxide nanoparticles (ZnO) concentration 2 g L-1 after a period of 6 days of incubation for the enhanced degradation of PRL (74 ± 0.01%) using yeast consortium. It was well in close agreement with the predicated value obtained by RSM model yield (74 ± 0.8%). Analysis of variance (ANOVA) showed F-value of 58.13, R2 of 0.9790, probability of

Rosemary (Rosmarinus officinalis L.) is a native Mediterranean herb, used to typically prevent oxidation of fats and oils in foods and cosmetics. Rosemary represents an effective source of natural antioxidants with analgesic, diuretic, digestive and anti-inflammatory effects. This study is carried out to properly evaluate if exogenous cytokinin applications typically led to hyperhydration symptoms or any histological variability in stomatal density, stomatal distribution, glandular trichomes density and size of leaf epidermis. The colloidal technique was used for observation and measurement of leaf epidermis characters. The plantlets during in vitro culture were developed on MS media and two different PGRs ratios (BAP) / auxin (NAA) were tested: (i) 1 mg l-1 / 0.1 mg l-1 (ii) 2 mg l-1 / 0.1 mg l-1. In vitro leaves of both categories were taken for analyses 4 weeks after the first subculture and were compared with in vivo ones. The study showed that in vivo plantlets have hypostomatic leaves, meanwhile, in vitro plantlets of both categories consist of amphistomatic leaves. In all cases, there are observed anisocytic stomata. In vitro leaves have a higher stomatal density, value which is increased in higher concentrations of BAP and thus transpiration rates are affected. In vitro specimens show about 3 times higher trichomes density in comparison with in vivo ones, but their diameter is about 2 times lower. Glandular trichomes size and density are affected by BAP concentration in nutrient media. These results convincingly show that in vitro culture can be used successfully to improve secondary metabolites production by intentionally altering the growing physical and chemical conditions.

The tomato (Solanum lycopersicum) is considered as one of the most important commercially grown vegetables which cultivated through the whole year. From several issues that may face the tomato breeders worldwide are susceptible to many viruses which cause yield losses and reduction in product quality. The goal of this work is to detect and determine some of the defense genes against viral infection diseases in different tomato cultivars infected with tomato mosaic virus (ToMV) by using two molecular techniques: differential display polymerase chain reaction (DD-PCR) and quantitative real time polymerase chain reaction (qRT-PCR) using pathogen related proteins (PRs) to identify and measure expression of pathogen related genes of ToMV. The obtained results have shown differentially expressed banding patterns due to viral infection and variable gene intensities were observed. There were 4 different bands selected randomly, purified and sequenced, the sequence analysis those bands revealed three up-regulated genes (putative permease gene; pathogenesis-related genes transcriptional activator PTI6 gene and linoleate 13S-lipoxygenase 3-1, chloroplast gene), and one down-regulated gene is endochitinase gene. We concluded that the role of the pathogenesis related genes either induced or suppressed during interaction between tomato plant and ToMV but also, the endogluconase (PR1) and chitin binding protein (PR4) expression increased during pathogen infection by ToMV, while the expression of chitinase (PR3) decreased/inhibited during infection by ToMV.
