Authors: Nyisalovits Andrea , Posta János , Czeglédi Levente , Juhász Diána , Babinszky László
Published: April 2019

The H-FABP gene was defined as a potential candidate gene influencing the fat deposition traits, primarily the intramuscular fat content. The aim of this study is to define whether the previously reported gene mutations are connected with the slaughter traits measured in a standard slaughterhouse. The study included data from 405 gilts and barrows from 2 different samples. The two chosen mutation (HFABP1: c. 103 T>C, HFABP2: c. 1970 T>C) were detected in one reaction with PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Lenght Polymorphism) method with HinfI restrictoin enzyme. The allel frequencies are as follows: 103T(H)=0.75; 103C(h)=0.25, 1970T=0.32; 1970C=0.68. A HFABP1 mutation has significant effect on backfat thickness and lean meat % at stable 1 (sample 1), but there were no effect at stable 2 (sample 2). The analysis of values of production traits, depending on HFABP2 genotype did not reveal significant differences. Based on this study we can’t get a clear conclusion on the impact of polymorphisms on production parameters. In the examined flock the allele frequency of mutation in 5 'UTR is identical to the literature data, i. e. the more favorable variant regarding the intramuscular fat content is predominant in the population.
Expansion of the small cable television counterparts of market leading commercial channels in view of Hungarian regional and social aspects
Authors: Illés Gabriella
Published: April 2019

Currently, there are 102 Hungarian-language television channels in Hungary. TV2 Hungary is the second largest commercial television channel. Current trends in the television market in Europe indicate that large channels are expanding their portfolios while at the same time selling their smaller units. This trend has now affected Hungary as well.

After having TV2 for 16 years, MTM-SBS Television Ltd. eventually expanded its portfolio with three new cable channels. The first new channel was FEM3, a channel directed at women, which was launched on January 1, 2010. A year later, the male channel, PRO4, was launched and finally, SuperTV2, primarily a premium entertainment channel, was launched on November 2, 2012. Although the main channel, TV2, remained free, the new pay channels on cable received a significant amount of investment from venture capitalists and Pro7Sat1 for the development of new content.

SuperTV2 is a premium channel. When the channel was launched, the goal was to target those viewers who had turned away from watching the increasingly less-sophisticated content on the commercial channels as well as those who were not drawn to the programming on public television. When the viewer stats were examined, the channel had proven itself. The premium brand of Super TV2 was successful in attracting new viewers and consumers and within a year it had gained a strong foothold over more than 100 other Hungarian-language channels.

Authors: Nessreen N. B. , Ammar A. K. , Ezzat A.
Published: April 2019

Some Egyptian rice genotypes [i.e. Japonica (Sakha 104), Japonica/Indica (Egyptian hybrid1) and Indica (Giza 182)] were investigated to evaluate the cooking and eating quality characters. High significant differences in grain shape were observed among rice genotypes. Hulling, milling and head rice percentage were higher in Sakha 104 than other rice genotypes, while Indica type (Giza 182) recorded the lowest values in milling and physical characters. No significant differences were found in chemical composition of the three genotypes of rice was recorded, but Giza 182 had the highest protein content. All Egyptian rice genotypes were low in gelatinization temperature and soft in gel consistency. Japonica and Indica rice varieties were low in amylase content, while Japonica/Indica rice variety was intermediate. The use of RVA is considered a good index for palatability evaluation for milled rice flour and starch. The Indica and Japonica/Indica types are low in breakdown viscosity, but higher in cooked pasta than Japonica type. Japonica type recorded the best score in panel test, followed by Indica type, while Indica/Japonica rice variety was the least accepted by Egyptian consumer.

Describing Fusarium diseases on maize in 2013 using data from several production sites
Authors: Szőke Csaba , Bónis Péter , Vad Attila , Dobos Attila , Micskei Györgyi , Marton L. Csaba
Published: April 2019

As in other parts of the world, the frequency of weather extremes has increased greatly in Hungary in recent years. This means that maize production is faced with greater risks from all aspects: nutrient replacement, irrigation, plant protection. This is especially true of fusarium diseases. In a continental climate, the pathogens causing the most serious problems are species belonging to the Fusarium genus. They infect the ears, which – besides reducing the yield – poses considerable risk to both human and animal health due to the mycotoxins produced by them. Depending on which Fusarium species are dominant at a given location, changes can be expected in the level of infection and in the quality deterioration caused by the mycotoxins they produce. Fusarium spp. not only damages the maize ears but when pathogen attacks the stalk, the plant dies earlier, reducing grain filling and resulting in small, light ears. In addition, the stalks break or lodge, resulting in further yield losses from ears that cannot be harvested. The degree of infection is fundamentally determined by the resistance traits of the maize hybrids, but also a great role in that region Fusarium species composition as well.
Slovenian economy in the grip of credit crisis – How to proceed?
Authors: Balogh Imre
Published: April 2019

The Slovenian economy has been through steep ups and downs post-EU accession (2004), and is at the crossroads again. The period 2004–2008 was characterized by balanced monetary and fiscal policies resulting in the adoption of the Euro (2007), coupled with overheated economic growth and propelling corporate indebtedness, fuelled by rapid credit expansion from cheap and abundant foreign funding.

The global financial crisis has exposed the “home-grown” vulnerability of the Slovenian economy, bringing about the second largest GDP fall (9.4%) in the Eurozone after Greece, with a double-dip recession (2009, 2012–13). Growth rebounced in 2014 to 2.6% from its low, but the competitiveness of the Slovenian economy continued to slide in international rankings. For further recovery Slovenia, squeezed by high public debt at 82% of GDP, credit contraction despite EUR 5bn state aid injected into the 70% domestically (basically state) owned banking sector, and the continued threat of massive bankruptcy and debt overhang in the corporate sector, has 3 fundamentally different policy options.

− Profound restructuring of the banking system and the real sector, on the basis of earnest privatization and voluminous FDI inflow.

− Slow creditless recovery due to half-hearted reforms in the financial system and corporate sector.

− Substituting wide-ranging micro level restructuring with Government-stimulated credit expansion, reproducing current tensions in even higher magnitudes in the future.

In the current state of the Slovenian economy, equity-led growth, combined with far-reaching institutional reforms seems the only choice in laying the foundation for long-term sustainable economic development. This study outlines the critical further steps in re-invigorating the financial system, utilizing also the proposals elaborated by the author and his banking team for the Slovenian macro policy decision-makers.
Modelling forestation alternatives

Published: April 2019

Agroforestry systems are part of the history of the European Union rural landscapes, but the regional increase of size of agricultural parcels had a significant effect on European land use in the 20th century, thereby it has radically reduced the coverage of natural forest. However, this cause conflicts between interest of agricultural and forestry sectors. The agroforestry land uses could be a solution of this conflict management. One real – ecological – problem with the remnant forests and new forest plantation is the partly missing of network function without connecting ecological green corridors, the other problem is verifiability for the agroforestry payment system, monitoring the arable lands and plantations.

Remote sensing methods are currently used to supervise European Union payments. Nowadays, next to use satellite imagery the airborne hyperspectral and LiDAR (Light Detection And Ranging) remote sensing technologies are becoming more widespread use for nature, environmental, forest, agriculture protection, conservation and monitoring and it is an effective tool for monitoring biomass production.

In this Hungarian case study we made a Spatial Decision Support System (SDSS) to create agroforestry site selection model. The aim of model building was to ensure the continuity of ecological green corridors, maintain the appropriate land use of regional endowments. The investigation tool was the more widely used hyperspectral and airborne LiDAR remote sensing technologies which can provide appropriate data acquisition and data processing tools to build a decision support system.
Effect of the plant density on different maize (Zea mays L.) hybrids yields and leaf area index (LAI) values
Authors: Murányi Eszter
Published: April 2019

We have investigated the plant number reactions of three maize hybrids of various genotypes in a small-plot field experiment. The plant numbers were 50, 70 and 90 thousand ha-1, while the row distances were 45 and 76 cm. The experiment was set on the Látókép Experimental Farm of Centre for Agricultural Sciences of the University of Debrecen in four replications on calcareous chernozem soil.

The assimilation area and the leaf area index have important role in development of the crop yield. The studied three different genotype maize hybrids reached its maximum leaf area index at flowering. The maximum leaf area index increased linearly with increasing plant density. The season-hybrids reached less yield and leaf area index. According to our experimental results, we have concluded that with the decrease of the row spacing, the yield increased in the average of the hybrids. The studied hybrids reached the maximum yield at 70 and 90 plants ha-1 plant density. We determined the optimal plant number that is the most favourable for the certain hybrid under the given conditions.The higher plant density was favourable at 45 cm row spacing than 76 cm. The hybrids reached the maximum grain yield at 45 cm row spacing between 76 712–84 938 plants ha-1, while the optimum plant density at 76 cm row spacing changed between 61 875–65 876 plants ha-1.

The leaf area index values between the applied plant density for the flowering period (July 1, 24), we defined a significant differences. In the archived yields were significant differences at the 45 cm row spacing between 50 and 70, 90 thousand ha-1 plant density, while the number for the 76 cm row spacing used did not cause a significant differences in the yield. There were significant differences between the examined hybrids of yields.
The role of disease resistance in the registration of crop varieties in Hungary
Authors: Gergely László , Poós Bernát
Published: April 2019

Variety testing including disease resistance test of the major crops has been carrying out since the 1960’s in Hungary. Testing for resistance of the new candidate varieties is performed in the so-called VCU (Value for Cultivation and Use) trials under natural infection and in special small-plot or micro-plot trials using different disease provocative methods. Disease resistance, especially those of multiple and horizontal-type (race non-specific, partial or durable) resistances, has recently become a key limiting factor in the state variety registration. The role of disease resistance in the decision-making process of variety registration is demonstrated on the examples of winter wheat and sunflower as two major field crops in Hungary.
Examination of resistance to Sclerotinia stalk and head rot in sunflower (Helianthus annuus L.) hybrids
Authors: Vojnich Viktor , Hüvely Attila , Palkovics András
Published: April 2019

Nowadays, phytopathogenic fungi cause the most serious yield loss in open field cultures, and sunflower (Helianthus annuus) is no exception to this phenomenon. Sclerotinia stalk and head rot (Sclerotinia sclerotiorum) is present in the whole area of Hungary, and can cause serious financial loss. In our experiment, sunflower hybrids were tested for resistance to Sclerotinia sclerotiorum infection. 16 sunflower hybrids were examined at the Experimental Breeding Site in Jászboldogháza. Pesticide treatment and also nutrient replacement were applied on the sunflower fields.
Slight damage of the great green bush-cricket (Tettigonia viridissima) (Orthoptera: Tettigoniidae) in some Hungarian maize fields
Authors: Bozsik András
Published: April 2019

Characteristic cricket damage was observed in two maize fields in northern Hungary, at Máriabesnyő, a district of Gödöllő. The damage level of the two fields did not differ significantly and continual monitoring of field1 showed also a stable infestation level. T. viridissima nymphs and a female were found and observed as feeding on maize plants. The crickets must have disappeared after 18.07. because no more fresh damage was observed after this date. The chewing’s number about on one and two % of the examined plants amounted one and six a plant and their size was between one and eight cm2. This infestation was quite little and might have caused apparently no yield loss. Compared this damage of T. viridissima with former Hungarian experience, this was the usual negligible damage despite the explicit draught in July and August 2015. As regards the global warming, orthopteran damage may be more obvious in the future.

Noctuidae are one of the most important Lepidoptera groups containing dangerous pest species. Monitoring and detection of these pest species is routinely performed by traps baited with sex-pheromones. Baits that attract both males and females were developed for improved pest management. First the effectiveness of different synthetic compounds was evaluated. We also tested semi-synthetic baits that contained both synthetic and natural components (wine and beer). These were more attractive for moths considering species richness and abundance. Disadvantage of this increased effectiveness is that the traps catch more non target, rare and even protected species. In this study we analysed the effect of semi-synthetic baits developed for Noctuid moths containing wine on other non-target Lepidopterans. In the six sampling sites traps caught 17158 individuals of 183 Lepidoptera species. The number of Noctuidae species was 124, while their proportion was 84.4%. The traps caught 813 individuals of 9 protected and 20 valuable species, which was only 4.7% of all Lepidopterans. In contrast the mean proportion of 33 dangerous and potential pest species was 31.3% (5375 individuals). Number and abundance of both protected and pest species were affected by landscape structure. The risks of catching non-target species was higher in species rich natural and semi-natural landscape. In homogenous arable lands the number and proportion of valuable Lepidopterans was not significant.

The disease syndrome caused by Waitea circinata, a soil-borne pathogen introduced in the past decade into Carpathian basin, visually indistinguishable of those caused by various Rhizoctonia strains in diverse host plant. Dicotyledonaceous species in general proved to be more tolerant to this new pathogen than monotyledonaceous ones. This mesophilic fungus can seriously damage cereals. The barley varieties, similarly to other plants, exhibited highly different individual reaction to soil borne infection, Bivoy being the most while Maresi the less tolerant among the 9 tested varieties. Two groups could be separated on the base of their response to Rhizoctonia; Jubilant, Bivoy, Pasadena formed one group being moderately tolerant and Anabell, Scarlett, Rex and Omega the other group of more susceptibles. Three significant factors influence on the virulence of Rhizoctonia strains comprised 62% of total variation.

The constat growth of the Earth’s population brings with itself a higher demand for food and protein not only in human nutrition but also for the feeding of livestock. Currently, the feed industry is mainly built onseed-based protein, wherethebaseplant is soybean, which is large lycovered by imports in Hungary, similar toother European countries. However, the long-term economically sustainable lifestock breeding demandschanges which has also worked out strategies. An alternative protein sources could be green leafy plants.

In current work the Jerusalem artichokes as an alternative source of protein was studied, compared to alfalfa as a valuable protein plant. Our results indicate that fiber fraction ofJerusalem artichoke shootswas 34 to 37% after pressing in the autumn period while alfalfa slightly lower values were obtained (30%). On the other hand extracted green leaf protein concentration was higher in alfalfa than in Jerusalem artichoke. Along with this higher protein content could be measured from the leaf protein concentration of alfalfa and almost each amino acids were more, as well comparing to Jerusalem artichoke.

Overall, the alfalfa proved to be advantageous as expected both in leaf protein extraction efficiency, both regarding the content of the protein in the Jerusalem artichoke. However, considering aminoacid composition and green biomass production, Jerusalem artichokecould be a promisingplant species asplant protein sourceinthefuture.

Published: April 2019

Selenium is an element of environmental interest owing to the narrow range between its nutritionally required and toxic concentrations in many organisms. Its mobility and bioavailability differ greatly depending on individual Se species. In this regard, in present study, the uptake and distribution of Se, the changes in Se content, and the effects of different concentration of Se in two forms of sodium selenite and sodium selenate on maize plants were measured in nutrient solution experiments to clarify their response to the two forms of Se. The results revealed that the Se content in shoots and roots of maize plants significantly increased as the Se level increased. Two Se forms behaved differently and the effects of toxic damage in samples which had been treated with selenite were much more than in the selenate treatments.
Chestnut tree: an appropriate choich for rural developement in Europe (review)
Authors: Kovács Gabriella , Radócz László
Published: April 2019

In chestnut plantations or in associations many pathogens and pests can be found. They are causing more than a hundred year problem in chestnut protection, for example the blight fungus Cryphonectria parasitica. Lot of breeders hybridized the Castanea sativa and Castanea dentata with the tolerant asian species. Nowadays the presence of Dryocosmus kuriphilus seems to be the main risk. However, there are more and more chestnut plantations in Europe because of the extensive growth of needs. The food industry produces many products from chestnut, but the wood industry also use it more and more. In most of European countries the chestnut stands represent landscape aesthetics and touristic value, but probably the number of farmers inquiring the plantation will be increase in Hungary.

Published: April 2019

Specific leaf area (SLA) of English oak (Quercus robur L.) and hornbeam (Carpinus betulus L.) as members of Querco robori-Carpinetum were investigated in two different habitat in terms of gap forest management: in the gap and in the inert forest. The artificial opening process of the forest resulted in more light for growing saplings and need for acclimatization. Photosynthesis is one of the most important ways for plant life and plant production basically influenced by altered light condition resulted in opening process. Efficient photosynthesis is important for plant life, plant production, but species-dependent plasticity of photosynthesis makes one species more tolerant, than others. The specific leaf area is acceptable parameters for characterising plant production, dry matter content and leaf structure. The dry matter content based on known leaf area is higher in oak both sun and shade leaves, than hornbeam. The different place of leaves in the canopy of trees did not influence the values of SLA.

Published: April 2019

The maize research was set up on chernozem soil at Látókép research area of the Centre for Agricultural Sciences University of Debrecen. We examined the following hybrids SY ARIOSO (FAO 300), P9486 (FAO360), DKC 4943 (FAO 410). The experience was set u pin three different plant density. These were 60, 76 and 90 thousand plant ha-1. The experience was set up in three different sawing date, early, average and late. The germination and growing dynamic measurements was measured in three hybrid, three sawing date, three plant density in four replication. well observed at the first sawing date (April 5) the soil was too cold therefore the germination was begins very slowly to be slowly increased. The second sowing time was the average (April 21) there the germination launch as soon as possible more rapid growth in the amount of heat. We experienced the most intense germination was in the case of the emergence late sowing date (May 5). Looking at the growth dynamics for the first two sawing date was side by side and almost equal to the maximum value. This is explained by the adaptive capacity of the maize to compensate for the sawing difference. For the third time, despite the delayed sawing the maize began to grow more dynamically than in previous sawing times due to the results of the initial good conditions it growth faster than halted in the second half of the season because of the high temperatures and lack of precipitation.

Authors: Czimbalmos Ágnes , Szűcs Lilla , Zsembeli József
Published: April 2019

In our study the nutrition reaction of four varieties of winter wheat (KG Bendegúz, KG Kunhalom, KG Kunkapitány, KG Széphalom) has been investigated. In the experiment the effect of twenty different nutrition doses on the yield and thousand kernel weight of the wheat varieties has been studied. Significant difference could be figured out among the yield and thousand kernel weight of the wheat varieties, so the choice of the proper variety determines the quantity of yield. KG Kunkapitány had the highest yield, while KG Széphalom had the highest thousand kernel weight in the experiments.

Investigating the effect of the nutrients on the yield the conclusion was that all nitrogen doses had significant yield increasing effect compared to the untreated plots, but among the 40, 80 and 120 kg ha-1 doses there was no statistical difference. In the case of phosphorus the 40 kg ha-1 dose showed statistically verifiable increase of the yield, while potassium doses have no influence on the yields. The thousand kernel weights reached the maximum values where the highest nutrient doses were applied.
Evaluation of critical factors determining the profitability of sweet maize
Authors: Kovács Evelin
Published: April 2019

The main goal of this analysis was to determine, whether the production of sweet corn competitive is from the point of view of profitability and identify the main factors determining profitability. The hypothesis of this research was that sweet corn production is profitable and output factors (yields, selling prices) affect most significantly the profitability. The total costs of production with irrigation are 560 000 HUF ha-1. Average yield is 18 t ha-1, while selling prices on average of the last 5 years were about 38 000 HUF t-1. The realisable profit in the sector was 248 828 HUF ha-1. Direct cost-related profitability was 48.6% and profit level 26%. Elasticity analysis pointed out that the changes of selling prices and yields affect profitability. The critical value shows the turning point of profitability, which was at the yield of 13.82 t ha-1. It can be concluded, the hypothesis was true, because sweet corn production was profitable compared to other field crops.

Effect of N, P and K fertilisers and their interactions in a long-term experiment on winter barley (Hordeum vulgare L.)
Authors: Surányi Szilvia , Izsáki Zoltán
Published: April 2019

The aim of this work was to analyse the effect of K, P and N supplies on the yield of winter barley in a long-term mineral fertilisation experiment with clearly distinct soil nutrient supply levels in order to develop fertilisation guidelines for winter barley growers. The experiment was set up in 1989 on a chernozem meadow soil calcareous in the deeper layers, applying all possible combinations of 4 levels each of N, P and K fertiliser, giving a total of 64 treatments.

The results of analyses performed in 2011 and 2012 can be summarised as follows:

In 2011, when rainfall supplies were deficient in the shooting phase, improved K supplies (324 mg kg-1 AL-K2O) increased the grain yield, but in 2012, when rainfall supplies were more evenly distributed, K supply levels in the range 210–335 mg kg-1 AL-K2O had no significant influence on the yield of winter barley.

An analysis of the P treatments revealed that, compared to the 119–133 mg kg-1 AL-P2O5 level (P0), better P supplies (186–251 mg kg-1) led to a significant increase in the grain yield.

In both years rising N rates significantly increased the yield up to an annual N rate of 160 kg ha-1.

      4. A K×N interaction could only be detected in the nutrient supplies of winter barley in 2011. The yield-increasing effect of N fertiliser was more    pronounced at better K supply levels, while K fertiliser led to higher yields in the case of better N supplies.

Behavior of some Hungarian wheat varieties to seed soaking in gibberellic acid under salt stress
Authors: Abido W. A. E. , Zsombik László
Published: April 2019

Various abiotic stresses including high salinity strongly affect seed germination. Three Hungarian wheat landraces Gamási, Fóti and Kartali have been tested for seed germination, seedling growth and chemicals parameters when seeds were soaked in gibberellic acid (GA3) at the concentrations of 0, 75 and 150 ppm and at four levels of salinity stress 0, 5, 10 and 15 dSm-1. A laboratory experiment took place at Research Institute of Nyíregyháza. Factorial Experiment based on Randomized Complete Block Design (RCBD) in four replications has been conducted. Seed soaking in GA3 before sowing significantly affected germination characteristics, seedling properties and the results of chemical analysis. The highest germination as well as K+ content of seeds were observed at seed soaking into 150 ppm GA3. However, Na+ and proline contents in seedling were decreased. The behavior of the tested Hungarian wheat varieties was genotype-dependent. Increasing salinity stress up to 15 dSm-1 significantly affected germination characteristics, seedlings parameters and chemical analysis. Fóti variety turned out to be the best at 150 ppm GA3 compared to the other two varieties. Moreover, it had the lowest Na+ and proline contents and highest K+ content.

Under 2500 km distance was a positive correlation between the genetic differentiation and different geographical areas. Hidden genetic barriers were found only Carpatian Basin. Could not be detected signs of genetic isolation in other regions. This will probably due to the unevenness of the sample collection, because these areas proportionally much fewer sequences were available. Therefore, is worth repeat this analysis after further sample collection, in the future.

Published: April 2019

The aim of this study was to determine the allelopathic potential of invasive species woolly cupgrass (Eriochloa villosa), common milkweed (Asclepias syriaca), bohemian knotweed (Fallopia x bohemica), and giant goldenrod (Solidago gigantea Ait.) on germination crop (Lepidium sativum L.). Experiments were conducted under laboratory conditions to determine effect of water extracts in petri dish bioassay. Water extracts from fresh biomass (leaves and stem) of invasive weeds in concentrations of 4 and 8 g/100 ml were investigated. All invasive plants showed allelopathic effect on germination. In giant goldenrod stem water extract experiment, allelopathic effect was less pronounced.

The cress germination was greatly suppressed with the woolly cupgrass, common milkweed and the giant goldenrod. The experiment showed that the seed germination depended on the concentrations and the plant material used (leaves and stem).

Apiarists let prepare by bee honey products containing medicinal drugs. Our aim was to prove that the active ingredients originated from the herbs are also present in the bee products. This publication focuses only to the chamomile (Matricaria chamomilla) containing feeding syrup and the difference between the various syrup phases. To fulfil this task, we developed a method analysing the non-volatile components of the syrup using the flowers of chamomile. The method involves a filtration followed by HPLC-MS analysis. The analyses and the data evaluations proved that the non-volatile components of the herb were transferred to syrup. As the characteristic components of certain herbs could be identified also in the syrup, it is obvious that the components responsible for the medicinal effects are also transferred.

An Implementation of the UTAUT Model for Understanding Students' Perceptions of Learning Management Systems
Authors: Alshehri Ahmed , Rutter M J , Smith Sally
Published: April 2019

The rapid growth of e-learning around the globe is inspiring various academic institutions to adopt it. Uptake is motivated by convincing benefits such as flexibility, accessibility and the management of course delivery. In fact, academic institutions place great emphasis on e-learning and are investing significantly in information technology infrastructures. However, in spite of this effort and investment, it seems that instructors and students do not always fully benefit from the learning technology and more often learning management systems (LMSs) remain underutilized. Thus, this study adopts the Unified Theory of Acceptance and Use of Technology (UTAUT) to study how people accept and use the Blackboard system. The data were analysed using Structural Equation Modelling (SEM) techniques to test the hypothesized research model. The empirical results found that technical support is fundamental in determining the acceptance and use of e-learning systems. The findings of the study may help to provide insights into a better approach to promote e-learning acceptance.
Runx1 and RORγt Cooperate to Upregulate IL-22 Expression in Th Cells through Its Distal Enhancer

Published: April 2019

IL-22 is a cytokine that plays a pivotal role in regulating tissue homeostasis at barrier surfaces and is produced by activated CD4+ Th cells. Currently, the molecular mechanisms regulating Il22 gene expression are still unclear. In this study, we have identified a crucial cis-regulatory element located 32 kb upstream of the mouse Il22 promoter, termed conserved noncoding sequence (CNS)–32. We demonstrated that CNS-32 acts as an enhancer in reporter assays and contains binding motifs for Runt-related transcription factor (Runx)1 and retinoic acid–related orphan receptor γt (RORγt). Mutation of these motifs significantly abrogated the reporter activity, suggesting a role for both factors in the control of enhancer-mediated Il22 expression. Runx1 and RORγt occupancy and elevated histone H4 acetylation at CNS-32 were evident, as naive T cells differentiated into IL-22–producing Th22 cells. Overexpression of Runx1 promoted IL-22 production by inducing RORγt and IL-23 receptor, all critical to Th22 cell induction. Although Runx1 alone enhanced IL-22 production in Th22 cells, it was further enhanced in the presence of RORγt. Conversely, short hairpin RNA–mediated knockdown of core-binding factor β, a cofactor essential for Runx1 activity, was effective in limiting IL-22 production. Collectively, our results suggest that IL-22 production is controlled by a regulatory circuit in which Runx1 induces RORγt and then partners with RORγt to direct Il22 expression through their targeting of the Il22 enhancer.
Critical issues and opportunities of emergency psychiatry in Italian emergency departments
Authors: Fraticelli Carlo , Casolaro Ilaria , Nigro Massimiliano
Published: April 2019

In Italy emergency physicians are the front line of care for patients with medical conditions such as trauma, heart attacks, strokes or psychiatric disorders. Triage represents the first clinical contact with the person to determine urgency of care, and includes initial risk assessment and determination of observation level. It is necessary to undertake mental health triage for all service users on entry to the Emergency Department (ED), alongside physical health triage. The recourse to emergency services for psychiatric complaints is increasing and ED providers are often the first contact a patient will have with psychiatric care. The organization of Italian EDs is constantly evolving under the pressure of various external forces (population aging, increasing use of new substances, immigration, choices of economic policy, and technological development). The psychiatric emergency service contact represents a key to addressing the presenting problem and it is a critical link for continuity of care. The management of psychiatric disorders is an evolving issue in Italy as in other countries. Research increasingly suggests the importance of specific training for EDs teams in order to provide appropriate handling in acute settings. Psychiatrists and ED physicians can – and should – play a fundamental role in promoting a targeted and shared training for emergency services to deal with crisis according to evidence-based medicine. Service organization, legal issues, safety, training and education are not well defined and established and still imply improvisation, while they deserve attention as fundamental prerequisite to implement specific treatment guidelines.
Social entrepreneurship as a catalyst to break the poverty trap: An analysis of the motivational factors in South Africa
Authors: Elliott Roger M.
Published: April 2019

Orientation: Social entrepreneurship has been advocated as a way of overcoming poverty but many of the studies purporting to explain the intention to become a social entrepreneur have resulted in inconsistent and inconclusive results.Research purpose: The purpose of this article was to examine the moderating influence of gender, family entrepreneurial background and culture (operationalised in this study as individualism or collectivism) on the antecedents to the formation of an intention to become a social entrepreneur in respect of financially disadvantaged students.Motivation for the study: Educational institutions in Africa have not implemented programmes to encourage students to become social entrepreneurs.Research design, approach and method: A questionnaire survey was conducted using a convenience sampling method in which a sample of 200 students was selected from a South African university. The data were analysed using hierarchical regression analysis.Main findings: Results provide strong support for the proposition that students’ gender and culture moderate the impact of the antecedents identified in this study (being close to the social problem and innovative) on the intention to become a social entrepreneur.Practical/managerial implications: There needs to be more collaboration and dialogue within and across all South African universities so that all educational programmes can be developed that embrace the challenges face by contemporary South African society.Contribution/value-add: This article demonstrates that current intention-based models are not adequate to explain the intention to become a social entrepreneur as they exclude extraneous personal and environmental factors.
Medical doctors’ awareness of radiation exposure in diagnostic radiology investigations in a South African academic institution

Published: April 2019

Background: Diagnostic investigations using radiation have become a critical feature of medical practice in recent times. However, the possibility of doctors’ underestimation of risks of over-exposure of patients to diagnostic radiation still warrants further evaluation.Objectives: To investigate doctors’ awareness of diagnostic radiation exposure at Dr George Mukhari Academic Hospital, South Africa.Methods: This was a cross-sectional, analytical investigation of the awareness of doctors about radiation exposure in diagnostic radiology investigations. A cluster sampling technique was employed to recruit 217 participants. Consent and approval of the participants were sought and obtained before questionnaire administration during departmental meetings between October 2017 and March 2018.Results: Of the participants, 80% had no formal training on radiation exposure and 33.8% of them correctly estimated natural background radiation. Correct estimates of the effective dose from a single-view abdominal X-ray (AXR) were expressed by 7.5%, quantity of radiation of a single-phase computed tomography (CT) abdomen by 30.3% and dosage from a two-view unilateral mammogram by 29.1% of the participants. More than 75% of participants agreed that children are more sensitive to radiation, but only 10.5% suggested medical termination of pregnancy for a woman who had CT abdomen and pelvis with contrast. Dosage and risk of inducing fatal cancer from common but more complex imaging procedures were poorly understood. Only the doctors of the radiology department showed a statistically significant (p < 0.0001) association with regards to their radiation awareness.Conclusion: Because of the high rate of poor awareness of radiation risks observed in this study, it is important to initiate, early in the medical curriculum for medical students, the need for a rotation in the Department of Radiology, similar to such rotations in other medical specialties.
