Immature, mature and endosperm-supported mature embryos of five different genotypes of common winter wheat Triticum aestivum L. Regardless of embryo source or genotypes, TDZ was found to exert a positive effect on the plant regeneration process by increasing the number of plants regenerated and transferred to soil by a factor of 1.
Within the embryo sources, immature embryos and within the genotypes, Bezostaja-1 responded to TDZ based common winter wheat regeneration treatments by producing the highest number of regenerants. However, above 0. The protocol developed in the present study can be used in future transgenic common winter wheat studies. The TL glow curves were generated for different kinetic parameters. At each time, one parameter was kept constant and others were changed.
The results of the CGCD programs were compared with the input kinetic parameters entered in the numerical solutions, and the success and failure of the CGCD methods were investigated as a function of input parameters. Statistics show that the number of automobiles in the world is increased at a high rate. Such huge number of automobiles comes out with enormous amounts of exhaust emissions.
According, there is a necessity to find solution s to such problem, which has become a threat to human health and environment. The goal of this work is proposing methods to reduce the exhaust emissions from automobiles by converting some components of such emissions into a fuel. In addition, the new fuel could be reused again in the automobiles.
Thus, this work has four main benefits. The first is to reduce emissions from automobiles in general. The second is to reuse the emissions as a fuel. The third is to save energy by using less gasoline fuel. The fourth benefit is using automobiles with lower fuel costs.
In addition, engine performance parameters are measured, including: brake power, torque, pressure inside cylinder, exhaust gas temperature and volumetric efficiency. Discussions and analysis of emissions trends as well as engine performance are presented.
Additionally, methods to reduce the automobile emissions by reformulating the emissions into new fuels are introduced and discussed. Such thermo-neutral chemical reactions offer the possibility of producing syngas in auto-thermal and non-catalytic reactors, with significant avoidance of generating CO2 emission.
Regarding CO emissions, the emissions stream can be treated using a water—gas shift reaction. Regarding CO2 emissions, we can use different oxide materials as sorbent for the CO2, such as calcium oxide, lithium zirconates and lithium silicates. Alternatively, hydrotalcite-like HTs materials could be an attractive option for CO2 sorption because of their high sorption capacity at lower temperatures.
Introduction: the article analyses the experiment of the Mordovian State Pedagogical Institute named after M. Evseviev on the creation of a system of training teachers for work in a children recreation camp using supplementary education resources.
The study was conducted on the basis of theoretical methods, as well as statistical methods. This study was aimed to investigate the potential therapeutic effect of Ginkgo biloba or quercetin and their mixture against acetic acid induced ulcerative colitis in rats.
Ulcerative colitis was induced in rats by administrated 6 ml 5. Therefore, potato tubers are called second bread. In addition, the potato plant has forage and industrial value. From this point of view, potato growing develops day in and day out, and sowing areas in the world are expanding.
Breeders get high-yielding varieties that are resistant to the negative effects of environmental factors. Nevertheless, when potatoes are grown, crop losses from various factors are observed. Pests, some of these factors that cause huge damage to the potato bush. Carrying out control measures against pests Colorado beetle, etc. Since the observation and recording of the number of pest populations, the determination of the biological effectiveness of the pesticides used does not require special difficulties.
But studying the bioecological features of soil pests, determining the density of populations and carrying out measures to combat them requires special skills.
Sometimes the measures taken to combat soil pests do not yield positive results. And this leads to excessive financial costs and loss of yield, which is unacceptable for farms. Therefore, it is necessary to thoroughly study the bio-ecological features of soil pests, in particular the bear, depending on the vertical zoning.
Since, depending on the vertical zoning, the bio-ecological characteristics of soil pests change. Investigations on learning of the factors restricting the area of the spreading have been carried out. Factors influencing to the manner of active life have been found out in the winter period.

The allelopathy is understood to be the influence that one culture exerts on the development of another. In this regard, both inhibitory and stimulatory or neutral effects may be cited. The objective of this study was to evaluate the allelopathic influence of the bean leaves extract Canavalia ensiformis , on the culture of jatropha curcas, applied in different concentrations.
Ten jatropha genotypes were seeded in 20 PVC containers, followed by preparation of an aqueous extract composed of pork leaves crushed in distilled water. The completely randomized design DIC was used as the evaluation methodology. The following parameters were analyzed: germination speed, percentage of germination, dry mass and fresh mass, leaf size and root size.
The extract of the leaves of pigs influenced the culture of jatropha in different ways in each one of the evaluated parameters, presenting in some moments neutral characteristics, inhibitory, or even stimulating action.
Keywords: Allelopathy influence. The therapeutic effects of Haloperidol HP , a classic antipsychotic drug, are accompanied by severe extrapyramidal side effects, resulting in movement disorders in patients. Our aim was to verify the influence of HP carboxymethyl chitosan nanoparticles on the brain functions of HP treated rats.
All the treated groups administered intraperitoneal for 21 consecutive days. Two days before the last dose, locomotors activity was assessed in open field test and catalepsy. However, the neuroleptic effect of HP was completely improved by haloperidol loaded with nanoparticles by decreasing the neurotoxicity via lowering lipid peroxidation, TNO contents and increasing antioxidant biomarkers in the cortex and striatum of the treated brains.
In conclusion, our study suggests that haloperidol loaded with nanoparticles could be suitable choice for treatment of schizophrenia for long time. Herein we carboxymethylchitosan water-soluble in wide range of pH by the reaction of chitosan with monochloroacetic acid in alkaline medium prepared. It was characterized by nitrogen content, carboxyl content and FTIR spectroscopy.
Carboxymethylchitosan was dissolved in distilled water to be ready for IP administration route for female mice as a carrier for anticancer drug doxorubicin after evaluation of its cytotoxicity. Liver tissues enzymes, ALT and AST activities were increased significantly after the administration of three acute doses of carboxymethylchitosan.
Moreover, urea and creatinine have recorded significant increases in kidney tissues. Artificial Neural Network ANN model is developed to predict the energy and exergy efficiency of roughened solar air heater. Total sixty sets of sample data, obtained by conducting experiments on solar air heaters with arc shape wire roughness on the absorber plates, have been used in this work. These experimental data and calculated values of thermal efficiency and exergy efficiency have been used in ANN model.
Neural model structured with back-propagation Levenberg-Marquardt LM learning algorithm. The ANN model developed with six parameters in input layer such as, the time of experiments, mass flow rate, ambient temperature, mean temperature of air, absorber plate temperature and solar radiation intensity, and two parameters: energy and exergy efficiency at output layer. The predictions were performed with 4 — 7 numbers of neurons in hidden layer.
Six numbers of neurons has been found in hidden layer as optimal value for ANN model on the basis of statistical error analysis. The neural model predicted results with minimum error. The values of R2 for predicted energy and exergy efficiencies are 0. The stastiscal results show that the proposed MLP ANN model successfully predict the energy efficiency and exergy efficiency of the solar air heater.

Taraxacum belorussicum Val. Tikhom, a poorly known and obligatory apomictic species, is an attractive plant material for studying the embryological, genetic and molecular mechanisms of apomixis. This work aims to obtain an efficient protocol for Taraxacum belorussicum regeneration. Four types of explants cotyledons, hypocotyls, meristems and roots that were taken from 2-weeks-old seedlings were used for in vitro cultures, and a fast and efficient protocol of T.
Studies on the role of PSK were done in three independent experiments, where the most significant factors were always light and darkness. Histological and scanning electron microscope images SEM of T. Plant material treated with aniline blue solution revealed the presence of callose in the cell walls of cotyledon and hypocotyl explants. The presence of extracellular matrix ECM and heterogenic structure of callus was also verified by scanning electron microscopy and light microscopy, confirming the high morphogenetic ability of T.
An efficient regeneration protocol for Taraxacum belorussicum , the obligatory apomict, was obtained. Application of PSK revealed the significance of light and darkness as a key factor in the morphogenetic response. A short darkness pretreatment 8 days in PSK medium was found suitable to enhance organogenesis.
Histological and scanning electron microscope images confirmed indirect organogenesis and somatic embryogenesis presence. The protocol can enhance the knowledge about this species in studying the embryological, genetic and molecular mechanisms of apomixis. Tikhom or dandelion, belongs to the genus Taraxacum Asteraceae Tikhomirov This genus includes many species which were used for the analysis of embryological, genetic and molecular aspects of apomictic mechanisms Janas et al.
In general, dandelions have also been a part of the natural medicine tool kit because of their medical qualities as diuretic, choleric, anti-inflammatory, anti-oxidative, anti-carcinogenic and melliferous. Based on their specific features and heavily urbanized areas of growth Erofeeva some Taraxacum species can play a role as temperate climate bio-indicators Jamshieed et al. It is an obligatory apomict that can produce embryos in a parthenogenetic manner, and can thus be used for the comparative study of parthenogenesis and somatic embryogenesis.
Apomixis is a type of plant reproduction during which the embryo is formed without full meiosis and syngamia, or omitting either of these two processes Noyes Taraxacum is characterized by the occurrence of diplospory apomixis Koltunow ; Hand and Koltunow , where a meiotic prophase is observed, but chromosomes do not create bivalents or metaphase tiles.
Instead, a restitution nucleus is formed which leads to generation of unreduced embryo sac cells after successive mitotic divisions Hand and Koltunow ; Rodkiewicz et al. Despite this, some apomictic species often maintain the ability to sexually reproduce, and certain seed parts have a zygotic origin Rodkiewicz et al. One of the common morphogenetic pathways leading to in vitro plant regeneration is organogenesis Huang et al.
A second possible path of in vitro morphogenesis is somatic embryogenesis, with somatic embryo induction from a somatic cell without fertilization Williams and Maheswaran Somatic embryos can be formed directly from the initial explant Kuo et al. The ratio between concentration of auxins and cytokinins has a crucial influence on in vitro morphogenesis Isah Phytosulfokine PSK , which was isolated for the first time from the Asparagus officinalis mesophyll Matsubayashi and Sakagami , being a peptide hormone, plays a role of regulatory molecule in the growth and development of plant cells, especially in somatic embryogenesis induction Lorbiecke et al.
Plant cell predisposition to undergo one of the two developmental pathways in vitro can be predicted using callose identification, as callose deposited in the cell walls is a marker of somatic embryogenesis. Callose may be also deposited in the place of damage as protection against microorganism infection Ellinger and Voigt According to the latest data, the presence of the Extracellular Matrix ECM in in vitro culture is a specific feature of morphogenesis or germinal tissues that is associated with ECM signaling functions.
In some cases, ECM may perform a protective function or is seen as a specific feature of callus surfaces formed under in vitro conditions Popielarska-Konieczna et al. The formation of ECM may be the result of stress factors or exposure to chemical agents that protect callus cells Bevitori et al. Apomixis is a phenomenon in which embryos arise by bypassing the process of fertilization, as also observed in embryo formation from somatic tissue cultured in vitro.
To what extent this similarity has its justification at the molecular or physiological level so far is not known and is an interesting research challenge, for which use of apomictic Taraxacum species seems to be the right choice. Therefore, tracing the morphogenetic abilities with the hope of obtaining an efficient somatic embryogenesis of this species is the first and necessary step for later comparative studies of these two developmental processes.
Based on the growing evidence suggesting that PSK has impact on acquisition of SE and morphogenesis, while there are no reports concerning these processes in T. All experiments were performed with seeds of apomict T. Afterwards, four types of explants: cotyledon Fig. S1b , meristem Fig. S1c , hypocotyl Fig. S1d and root Fig. S1e were obtained from the 2-week-old seedlings Fig. S1a and cultured on several media according to different experimental systems with 25 explants per Petri dish, in three repetitions.
Within this time, all plantlets acclimatized successfully. Histological samples were stained using 0. To detect cell structures such as the cytoplasm or nuclear cell, the slides were first warmed, then stained with 0. After dehydration in a graded ethanol series, samples were dried at the critical point of CO 2 by use of a Quorum Technologies E Quorum Technologies Ltd.
Samples stained with aniline blue were analyzed with an EX Nikon Corporation excitation filter. Two paths of callus development, indirect organogenesis and somatic embryogenesis arrow of T. During the culture of selected T. Meristem explants also produced callus, but in a moderate amount, while callus was formed with the slowest and the least efficiency on cotyledon explants.
Explants cultured on the control medium did not produce callus data not shown. The weakest development of callus was noted on cotyledon explants. The callus color was from light to dark green, as well as white, yellow and brown. Meristem, cotyledon and hypocotyl explants showed the greenest shades, thus the largest amount of chlorophyll in callus cells, while shades of brown were visible on root explants. The intensity of morphogenetic response organogenesis of selected types of explants was expressed as the average number of adventitious shoots produced during in vitro culture.
The anecdotal presence of somatic embryogenesis did not allow for its proper quantification. Organogenesis efficiency of T. The figures show the results from 25 independent explants per one Petri dish in three repetitions. The presence of adventitious shoots was observed on the surface of all type of explants and thus their regenerative efficiency was calculated. Analyses also showed that organogenesis efficiency in terms of average amount of regenerated plants was highest on meristem and hypocotyl explants, while that of root and cotyledon explants was the lowest Fig.
In addition, indirect organogenesis proceeded with different efficiency on the majority of all types of explants. The development of T. Results obtained clearly indicate that the addition of PSK to the medium increased the intensity and efficiency of the organogenesis process.
However, the explants were in a poor condition: part of them began to quickly degenerate and, under these conditions, most explants were overgrown with callus especially the root explants. During culture under light conditions, a significant improvement was evident, the color of explants changing from brown yellow to bright and dark green. The combination of PSK with auxins and cytokinins enhanced the process of indirect organogenesis and had a positive influence on somatic embryogenesis induction.
For cotyledon, hypocotyl and meristem explants, the use of a medium without PSK was much more favorable. However, root explants developed better on a medium with PSK. It should be noted that the used media differed not only in the presence or absence of PSK, but also in the auxin and cytokinins content. Still, the interaction between PSK, auxins and cytokinins did not significantly affect the development of explants.
In the case of hypocotyl, meristem and root explants, the use of PSK without other agents, slightly stimulated the organogenesis process. However, in the case of cotyledon explants, the use of PSK without auxins and cytokinins did not bring a desired effect.
However, the effect of PSK on the formation of callus was noticed while under dark conditions. Observation of explants in the light showed a significant improvement in their condition as they turned from brown yellow to green due to the restoration of chlorophyll.
PSK had a positive effect on somatic embryogenesis visible on cotyledon explants , but deformed somatic embryos which were not able to convert were observed. Such tissues did not produce regenerated plants and the culture was terminated at this stage. Cross-section of T. PAS reaction. Results revealed structures similar to somatic embryos formed from explant tissues overgrown with endogenous callus Fig. These structures were deformed at the later stage of development.
The PAS staining showed clearly visible vascular bundles in the embryo cotyledon explant and the absence of starch in explant and embryo tissues Fig. Secondary xylogenic centers were seen within the mesophyll, the explant epidermis was noted to be continual Fig. This effect may indicate formation of the apical meristem.
Based on the continuity of the epidermis, the presence of endogenous callus was indicated. Moreover, well-formed long vessels were observed in the place where secondary meristematic centers were formed, while well-visible nuclei and dense cytoplasm were reported in small cells surrounding vessels.
This effect indicates the meristematic nature of these cells. Still, despite many alterations, the tissue maintained compact nature and cells adhered closely to each other. Histological analysis of the meristem explant showed the presence of secondary meristematic centers, but the continuity of tissues was not maintained. Many intercellular spaces were ECM enriched Fig.
However, continuity of epidermis was not maintained, and an exogenous callus was observed next to endogenous callus Fig. Differences in size and shape of cells, the presence of many cytokinesis at various stages of advancement and the formation of xylogenic centers were observed Fig. This was confirmed by the presence of proteins and the accumulation of starched in these cells, as well as their abundant cytoplasm.
The appearance of shoots from the meristematic tissue and the presence of the first younger leaves were observed Fig. Herein, circular abundant meristematic and xylogenic centers, dense cytoplasm and large dividing nuclei were noted in the meristematic tissue—indicating high mitotic activity. The differentiation of callus parenchyma cells into meristematic tissues was also seen.
This is a natural development. Histologic analysis of the hypocotyl explant revealed changes in the axial roller and parenchyma of the primary cortex cells Fig. Endogenous callus with large spaces between cells was also present within the primary cortex Fig.
