Sustainable water use implies the simultaneous protection of water quality and quantity. Beyond their function to support human needs such as drinking water provision, transportation and recreation freshwater bodies are also habitats. Conceiving them as water users on their own with respective biological, physico-chemical and morphological requirements could help maintaining their healthy state. Healthy

Occurrence of the smallest phototrophic microorganisms (photoautotrophic picoplankton, APP) in Lake Balaton was discovered in the early 1980s. This triggered a series of systematic studies on APP and resulted in the setting of a unique long-term picoplankton dataset. In this review, we intend to summarize the obtained results and to give a new insight on APP ecology and diversity in Lake Balaton. According

Science, particularly in life sciences and biotechnologies, is continuing to make remarkable progress in the past decade. This has been possible due to the governments and people recognizing that scientific discoveries bring development and prosperity to the nation. The new trend in research is to collaborate across disciplines with large teams of participants across the globe. This has brought success

In this review, I would like to summarize the current knowledge on the microbiology of soda lakes and pans of the Carpathian Basin. First, the characteristic physical and chemical features of these sites are described. Most of the microbiological information presented deals with prokaryotes and algae, but protists and viruses are also mentioned. Planktonic bacterial communities are dominated by members

Human periodontal ligament stem cells (PDLSCs) play an important role in periodontal tissue regeneration. The generation of PDLSCs from human induced pluripotent stem cells (iPSCs) by simulating the development pattern of PDLSCs in vivo provided a new way to obtain a large and stable source of PDLSCs. However, animal-derived components were still necessary for current differentiation protocols, which

Maintaining and, where possible, improving the ecological status of our water resources are of particular importance for the future. So, one of the main drivers of landscape design must be to protect our waters. In this study, we carried out an evaluation of four hydrologic ecosystem services (HES) in the Zala River catchment area, the largest tributary of Lake Balaton (more than half of the lake’s

Diabetes mellitus (DM) is a group of metabolic diseases characterised by hyperglycaemia resulting from defects in insulin secretion, insulin action, or both. Insulin therapy might be affected by specific metabolic enzymes and transporters. There are conflicting reports in the literature on the role of adenosine receptor A2B (AR2B) in skeletal and cardiac muscle glucose metabolism. This study aims to

Aging is associated with decreased cellular cysteine uptake, which acts as a precursor for glutathione biosynthesis. Whey protein, a liquid aspect of milk, is an effective cysteine delivery system. The study was undertaken to evaluate the potential role of whey protein concentrate (WPC) on the redox biomarkers during aging. Male Wistar rats were divided into following four groups: young control (4 months

Hybridization associated with polyploidization and apomixis is a frequent mechanism of speciation. Sorbus is a genus with ongoing hybridization resulting in a polyploid complex with different parental lineage. Triparens is the smallest hybridogenous subgenus of Sorbus so far known to comprise only two taxa, S. intermedia and S. × liljeforsii that combine the genomes of three taxa (S. aria agg., S.

The potential inhibitory effect of diverse triazolyl-ferrocene steroids on key enzymes of the estrogen biosynthesis was investigated. Test compounds were synthesized via copper-catalyzed cycloaddition of steroidal azides and ferrocenyl-alkynes using our efficient methodology published previously. Inhibition of human aromatase, steroid sulfatase (STS) and 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1)

Pregnancy is a crucial period with an increased need to supply necessary minerals for both the mother and the developing foetus and with a tendency of altering the maternal bone mineral density when there is no balance between demand and supply of these minerals. This study evaluated the influence of genistein on the maternal bone and placenta mineral composition. Pregnant rats were grouped into control

Polyamines (PAs) are positively charged amines such as putrescine, spermidine and spermine that ubiquitously exist in all organisms. They have been considered as a new type of plant biostimulants, with pivotal roles in many physiological processes. Polyamine levels are controlled by intricate regulatory feedback mechanisms. PAs are directly or indirectly regulated through interaction with signaling

Some recent results reported that aspirin (acetylsalicylic acid) had a positive effect on the treatment of certain types of cancer. However, the results cannot be generalized and it is not always clear whether it is a direct anticancer effect or a general health effect. Since plants produce different amounts of salicylic acid, we have sought a relationship between the salicylic acid content of some

In 2019, the record for the most expensive drug was broken at US$2.1 million per patient. The high costs of new drugs are justified by the pharmaceutical industry as the expense required for maintaining research and development (R&D) pipelines. However, this does not take into account that globally the public pays for between one to two-thirds of upfront R&D costs through taxpayers or charitable donations

This reflective essay is inspired by a roundtable discussion at the World Science Forum on the question ‘Are there ethical limits to what science can achieve and should pursue?’ I argue that, amid the conflicting trends of ‘technological utopianism’—extreme faith in technological solutions; and ‘post-truth’ politics—the populist pushback against the universality of science, the conditions for ethical

Kallar grass (Leptochloa fusca) is a highly salt-tolerant C4 perennial halophytic forage. The regulation of ion movement across the plasma membrane (PM) to improve salinity tolerance of plant is thought to be accomplished with the aid of the proton electrochemical gradient generated by PM H+-ATPase. In this study, we cloned a partial gene sequence of the Lf PM H+-ATPase and investigated its expression

The exotic honey locust (Gleditsia triacanthos) is often planted as ornamental tree in urban parks. In Hungary, it occasionally escapes cultivation, in other countries it has already become invasive, and thus, further spread cannot be ruled out. The production of copious long-lived seeds may contribute to its invasiveness. We investigated the soil seed bank of honey locust growing in urban parks of

Our knowledge about the origin of landbirds (Telluraves) is increasing rapidly but new questions are arising because of the contradictory findings from previous studies. All of the major lineages in the highly diverse clade of Neoaves have a Gondwanan origin, although studies often disagree about the origin of different sub-lineages. Nevertheless, understanding the biogeographical histories of these

The vast majority of floristical and coenological studies focus on the natural vegetation and its remnants in urban environments; however, there is an increasing interest in the systematic exploration of built environments. This survey of the inhabited areas of Budapest launched in 2018 applied a new and detailed methodology. The territorial units of the survey were street sections, where the presence

Urinary tract infections (UTIs) are some of the most common infections affecting humans worldwide. Occurrence of atypical, lactose non-fermenting, biochemically “inactive” strains of E. coli in clinical material has been described in the literature, which may cause a significant diagnostic challenge. The present retrospective microbiological study was carried out using isolates and data collected between

Brassica oleracea cv. Pride of India is one of the most promising vegetable cultivars commercially grown as cash crop in Himachal Pradesh, India. However, its overall production is severely hampered by diamondback moth (Plutella xylostella), a notorious pest. To avoid yield losses caused by this pest, cryIAa gene was introduced into cabbage cv. Pride of India using Agrobacterium-mediated transformation

Expansion and urbanization process of wild boar (Sus scrofa) populations lead to serious human–wildlife conflicts in many cities, e.g. in Budapest, Hungary. In this study we evaluated the penetration potential of the species into the inner urban areas by identifying the occurrence of wild boar and the quality of the habitat patches for them along an urban gradient from the periphery towards the centre

In this study, an in vitro α-chymotrypsin aggregation model was used to demonstrate that certain extracts of commercial coffees effectively inhibit protein aggregation in 55% ethanol at pH 7.0. To detect the anti-amyloidogenic effect of the various coffee extracts, turbidity measurements and Congo red binding assays were performed as well as the determination of the total polyphenol content of the

This paper reviews the scientific literature published on synanthropic spiders in three Carpathian Basin countries—Hungary, Slovakia and Romania. A total number of 204 spider species have been reported from human constructions. Most of the 204 spider species (165 species) found in buildings were only occasional visitors, so-called asynanthropic species with typically low abundance. On average, eusynanthropic

Certain companion animals’ relationship to humans is analogous to child–parent attachment. Further, pet-keeping is associated with less physical and psychological health problems and animal-assisted interventions ameliorate depressive symptoms. Accordingly, cognitive representations of pet-keeping and parenthood may be related, and pet-keeping may protect against postpartum depression symptoms (PPDS)

Cities represent novel environments where altered ecological conditions can generate strong selection pressures leading to the evolution of specific urban phenotypes. Is there evidence for such adaptive changes in urban populations which have colonized their new environments relatively recently? A growing number of studies suggest that rapid adaptations may be widespread in wild urban populations,

István Sándor was a monk and deeply impressed by the spirituality of the Salesian Society. On 24 July 1946 he made his perpetual votes as a Salesian brother. In 1950 the Communist Party banned the operation of religious orders including the Salesian Order. In 1951 the Internal Security Corps was informed about “illegal” activity of István Sándor. He was arrested on 28 July 1952 and sentenced to death

Twenty chickpea cultivars were germinated under control and different levels of salt stress induced by sodium chloride and out of these, three desi (PDG 3, GL 12003, C 106) and two kabuli (FLIP-08-125-C and GLK 28127) cultivars were selected on the basis of embryonic axis growth, biomass, salinity stress tolerance index. Antioxidative enzymes, non-enzymatic antioxidants proline and proline metabolizing
