Numerous different agroecosystems (alfalfa, apple, cereals, oilseed rape, maize, sunflower fields and plantations, a pasture and a compost hill) were investigated on the basis of the soil dwelling mites in two parts of Hungary. Twenty-three species of Mesostigmata, 13 Oribatida, one Astigmata and one Prostigmata are listed from these specific ecosystems, of which nine species, Alliphis halleri (G. and R. Canestrini, 1881); Antennoseius avius Karg, 1976; Antennoseius pannonicus Willmann, 1951; Arctoseius eremitus (Berlese, 1918); Cheiroseius bryophilus Karg, 1969; Leioseius insignis (Hirschmann, 1963); Oppiella loksai (Schalk, 1966); Punctodendrolaelaps fimetarius (Karg, 1965); Rhodacarellus perspicuus Halaśkova, 1958 are new to the Hungarian fauna.

Five different bamboo plantations were investigated on the basis of the leaf litter inhabiting mites. 11 Mesostigmata and 10 Oribatida are listed from the leaf litters, of which three species, e.g. Vulgarogamasus kraepelini (Berlese, 1905), Nothrus parvus Sitnikova, 1975, Metabelba paravulverosa Moritz, 1966 are new to the Hungarian fauna.
The aim of this study is to present a situation assessment within the framework of a comprehensive study of the social services for people with mental illness in Hungary. After setting the historical background, we describe in detail the current services, their anomalies, and the ongoing implementation of a strategy to deinstitutionalize them.
Materials and methods
We reviewed the related academic literature and systematically collected and elaborated upon legal documents, decisions, and data from national databases.
We established that a paradigm shift is taking place in the social care of people with mental disorders in Hungary. The lack of human resources, the paternalistic, institution-centered attitude, the mass supply of social services in dilapidated buildings, and the stigmatization of patients are among the greatest problems. Cooperation between the health and social sectors is inadequate and, in the interests of patients, needs to be improved.
Hungary needs a complex, integrated, health-and-social-care supply system for people living with mental illness, one that takes into account both personal needs and assistance to recovery. In the continuation of the deinstitutionalization process, emphasis should be placed on social sensitization.

Extended research has been carried out on the antimicrobial properties of herbs belonging to the family Asteraceae, trying to establish their potential use in natural pest control, in addition to human medicinal applications. For testing and quantifying antibacterial activity, most often standard microbial protocols are used. In this study the aggregate bactericide effect of four species (
L.) was screened using the
bioluminescence inhibition bioassay. The two
species which have well-established use as antibacterial, exerted the highest toxicity. Toxicity of
fell into the same range, although this herb has restricted use in human medicine. On the contrary,
, which is widely recommended against inflammations, showed significantly lower toxicity.

(Artemia) nauplii was used to asses the toxicity of rotenone, MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine), MP+ (1-methyl-4-phenylpyridinium) and the effect of L-DOPA co-treatment with rotenone. Rotenone had a dose dependent effect on mortality (LC50: 0.37 ± 0.04 μM mean ± S E, n = 24), while MPTP and MP+ proved to be toxic in millimolar range (LC50: 0.21 ± 0.09 mM and 0.20 ± 0.08 mM, respectively, n = 4). L-DOPA (50–200 μM) co-treatment increased the survival of the rotenone-treated animals (LC50: 0.51 ± 0.23 μM, 1.03 ± 0.66 μM, and 0.76 ± 0.52 μM, respectively). In the whole body tissue homogenates of Artemia, sublethal (up to 0.3 μM) concentrations of rotenone increased the glutathione S-transferase (GST) activity by up to 50 about percent (LC50: 53.3 ± 6.8 nM/min/mg protein, against 34.7 ± 3.6 nM/min/mg protein, n = 4). Nauplii treated in 100 mM L-DOPA and rotenone together showed further increase of GST activity all across the range of rotenone concentrations. These results on Artemia nauplii show similarities with other animal models, when complex I inhibitors were tested. Biochemical measurements suggest a protective role of L-DOPA by increasing the GST activity as part of the intracellular defences during toxin-evoked oxidative stress.

The main function of the Kis-Balaton Water Protection System is to retain nutrients and total suspended solids, thus protecting the water quality of Lake Balaton. In this paper, the toxic nature of the sediment in the 2nd reservoir of the KBWPS has been characterised, using a battery of tests: Vibrio fischeri acute bioassay on whole sediment samples, and V. fischeri bioassay on pore water and elutriate samples. The latest version of the V. fischeri bioluminescence inhibition was applied, the Flash assay which uses a kinetic mode and is able to detect the toxicity of solid, turbid/coloured samples. Whole sediment toxicity showed a clear spatial distribution of toxicity, in parallel with elutriate toxicity. However, no pore water toxicity was detected, leading to the conclusion that contaminants are not water soluble.

As locus-specific co-dominant PCR-based markers that allow semi-automated, high-throughput investigation technologies, microsatellites are ideal tools for genotype identification. Eleven of a set of 114 microsatellite markers available at the Agricultural Biotechnology Center proved to be suitable to distinguish between the parents of at least one of nine sweet pepper hybrid combinations. Markers with the highest information capacity were found to be capable of distinguishing between the parents of four different hybrid combinations and exhibited up to four different alleles in 18 haplotypes.

Grain fructans play an important role in the physiology of wheat plants and also impact on the health of consumers of wheat-based products. Given the potential economic importance of fructan levels, if genetic variability could be identified for this trait, it may be a potentially useful breeding target for developing climate-resilient and nutritionally enhanced wheat varieties. The aim of the current study was to screen 78 genetically diverse Australian wheat varieties released between 1860 and 2015 to determine if historic breeding targets have resulted in changes in fructan levels and to identify potential breeding parents for the development of varieties with specific fructan levels. The impact of seasonal conditions on grain fructan levels were also investigated. Analysis of the varieties in this study indicated that historic breeding targets have not impacted on grain fructan levels. Fructan content in flours varied between 1.01 to 2.27%, showing some variation among the varieties. However, a significant variation in fructan levels was observed between different harvest years (mean values for 2015 and 2016 samples were 1.38 and 1.74%, respectively). While large variations in fructan contents of different varieties were not found, there were some varieties with consistently higher or lower fructan contents which could be used to breed varieties with specific fructan levels.

Consumption of “gluten-containing” diet causes disease for a significant minority of people who consume foods derived from wheat, rye, barley, and possibly oat. The fact is, however, that in several types of diseases related to the consumption of “gluten-containing” cereals, the trigger compounds are not components of gluten. The current view of medical experts is that, excluding people suffering from celiac disease, the majority of individuals who are feeling better on the “wheat-free” or “gluten-free” diet could select a food containing much healthier, low level of fermentable oligosaccharides (often called as FODMAP). To satisfy the specific health related demands of certain consumer groups, the challenge is in front of cereal breeding to develop new, “healthier” germplasms, suitable to produce such products by the food industry. This report aims to give an overview of some aspects of recent developments in this booming area, (i) summarizing the up-to-date knowledge on cereals-related health disorders; (ii) reporting on the status of developing celiac-safe cereals, and finally (iii) highlighting the potential of developing “healthier” spelt-based cereal products through the progress in an ongoing spelt breeding program.

Selenium (Se), a main antioxidant component in cereal grain, is essential for animals and human health reducing risk factors of many dangerous diseases. Over the past decades, intake of this trace element had dropped due to low Se content in large areas of European countries including Hungary. Se-rich, high-protein cereal products became a focus for both animal feed and human consumption. In the study, we examined the following: i) grain Se concentration of wheat (
L.) and triticale (
Wittm.) intake to detect intra-and inter-genetic variations and ii) possible comparison relationship of this trace element to end product integrity, quality and relevant technological aspects. Se content of the whole meal grain was tested via atomic absorption spectroscopy (AAS). Despite generally poor Se soil content of the experimental area where samples were collected, significant differences were found for both species. In general, triticale contained higher Se concentration than wheat did. Spring type cereals had significantly higher grain Se and protein concentration than those of winter ones. Grain Se content showed positive correlation with magnesium, copper, zinc, manganese, tocopherol and crude protein concentration. Remarkable intra-specific variations were found in Se concentration, however in future, additional studies, methods and resources will be required for identifying ways of increasing Se content in cereal foodstuff and feed.
