Based on the findings of common project 29 years ago, the Scandinavian J. of Immunology accepted and published our paper entitled by “FcγR-Dependent Regulation of the Biosynthesis of Complement C3 by Murine Macrophages: the Modulatory Effect of IL-6” (Bajtay et al. in SJI 35:195–201, 1992). In this report we attempt to review the previous results and evaluate them with our current concepts on the interaction

Calluna vulgaris (L.) Hull belonging to Ericaceae family occurs mostly at sour habitats in subalpine regions in Europe. The species is cultivated in many countries, but it is known as medicinal plant because of polyphenols and aucubin as main compounds. In this work, the polyphenolic, flavonoid, and tannin content, as well as the antimicrobial and antioxidant activity of the aerial part, were evaluated

The aim of present study was synthesize 6-(2-hydroxyethyl)cyclohex-3-enol (11) and investigate its antioxidant properties in barley plants under drought stress. For this aim, 1,4-cyclohexadiene (7) was subjected to [2 + 2] ketene addition reaction with dichloro ketene and the chlorine atoms were reduced. After that, the cyclobutanone ring was converted to a lactone ring and the lactone ring was reduced

The global catastrophe of natural biodiversity and ecosystem services are expedited with the growing human population. Repercussions of artificial light at night ALAN are much wider, as it varies from unicellular to higher organism. Subsequently, hastened pollution and over exploitation of natural resources accelerate the expeditious transformation of climatic phenomenon and further cause global biodiversity

The research aims were to study salicylic acid (SA) effects on mycorrhiza [hyphal width (HW), vesicle diameter (VD) and mycorrhizal colonization (MC)] and interaction between them on greenness index (GI), drought tolerance index (DTI), antioxidant enzymes activities, and seed yield of linseed under drought. A factorial experiment was conducted in an open-field place with mycorrhiza [non-inoculation

Hyperlipidemia is one of the leading causes of, atherosclerosis, and cardiovascular disease. In this study, we evaluated the protective role of hesperidin (HES) against lipidemic stress in a hyperlipidemic model of rats. We developed a hyperlipidemic model of the rat through an i.p dose of poloxamer-407, 0.5 g/kg body weight for 3 alternative days in a week for 30 days and rats were supplemented with

The genus Solanum exhibits a wide range of variability in morphology, flavor, and tolerance to biotic and abiotic stresses. Phenotypic and genetic variability using ISSR and RAPD markers of Solanum incanum distributed in Al-Baha province of the Kingdom of Saudi Arabia is assessed. Thirty samples are representing three different locations: Baljershy, Aqeeq, and Tohama, besides twenty-five samples representing

4-aminopyridine (4-AP) is a widely used drug that induces seizure activity in rodents, especially in rats, although there is no consensus in the literature on the dose to be used in mice. The aim of the present study was to investigate the effect of the intraperitoneal administration of 4-AP in two doses (4 and 10 mg/kg) in vivo. EEG, movement, and video recordings were made simultaneously in male

The era dominated by the liberal world order, dating back to the end of World War II in 1945 and gaining unchallenged dominance with the fall of the Berlin Wall in 1989, is now coming to an end. Yet the universal principles that the era personified in its rhetoric, and in the best of its actions, lives on. The global community has a moral obligation to continue on its journey to build a more equitable

Animal experiments have served to improve our knowledge on diseases and treatment approaches since ancient times. Today, animal experiments are widely used in medical, biomedical and veterinary research, and are essential means of drug development and preclinical testing, including toxicology and safety studies. Recently, great efforts have been made to replace animal experiments with in vitro organoid

Y-DNA and mtDNA have been a widely used tool not only in forensic genetic applications but in human evolutionary and population genetic studies. Its paternal or maternal inheritance and lack of recombination have offered the opportunity to explore genealogical relationships among individuals and to study the frequency differences of paternal and maternal clades among human populations at continental

Scientific enquiry and the communication of science are essential to achieving development goals. The demand for evidence-based policy poses a challenge to maintaining the ethical conduct of science. The modern scientist faces intense competition in light of the changing nature of collaborative efforts, the quickening pace and increasing complexity of research endeavours and a growing emphasis on commercialisation

The present study aimed to evaluate TEM-1 or -2 and SHV-1 β-lactamases frequency in multidrug-resistant (MDR) Enterobacteriaceae isolated from patients’ urine in northern Iran. The resistance pattern to 20 antibiotics and ESBL production in 200 MDR Enterobacteriaceae was detected using the disk diffusion test and double-disk synergy test (DDST), respectively. Multiplex PCR was applied to detect blaTEM-1

In the present study, the prokaryotic community structure of the water of Lake Balaton was investigated at the littoral region of three different points (Tihany, Balatonmáriafürdő and Keszthely) by cultivation independent methods [next-generation sequencing (NGS), specific PCRs and microscopy cell counting] to check the hidden microbial diversity of the lake. The taxon-specific PCRs did not show pathogenic

This paper aims to help policy makers with a characterization of the intrinsic value of biodiversity and its role as a critical foundation for sustainable development, human health, and well-being. Our objective is to highlight the urgent need to overcome economic, disciplinary, national, cultural, and regional barriers, in order to work out innovative measures to create a sustainable future and prevent

Bioactive peptides (BPs) are 3–20 amino acid residues, with a molecular weight lower than 6 kDa; originated from the breakdown of proteins by endogenous and exogenous peptidases. While intact in protein these peptides do not exert any biological activity, but as they release from their parent protein, they exert various pharmacological activities such as antidiabetic, antihypertensive, anticancerous

Plant growth regulators (PGRs) play a pivotal role in increasing vegetable productivity, but they have many drawbacks that can include health and safe concerns of consumers. In this study, the plant growth regulators (PGRs) contents of 111 Brassica juncea (L.) Czern. samples collected from six main suburban areas of Hanoi, Vietnam, were determined by liquid chromatography—electrospray tandem mass spectrometry

During coke production, large volume of effluent is generated, which has a very complex chemical composition and contains several toxic and carcinogenic substances, mainly aromatic compounds, cyanide, thiocyanate and ammonium. The composition of these high-strength effluents is very diverse and depends on the quality of coals used and the operating and technological parameters of coke ovens. In general

Water deficit is one of the most limiting factors for plant growth and production. Polyamines are osmo-active compounds and have important roles in plant resistance to water limitation. A pot experiment was undertaken in a greenhouse as factorial based on complete randomized block design with three replications to assess the physiological and biochemical responses of safflower to different levels of

Halophyte is a distinctive group of plants that can survive, even well flourish, at a concentration of Na+ and Cl− ions along with heavy metals that would be lethal to most of the agricultural crop species. These capabilities make certain halophytes good contenders for phytoremediation through phytoextraction or phytostabilization of the salt and heavy metals (HMs) in polluted soils. Thus, the present

Arbuscular mycorrhizal (AM) fungi play an important role in improving the plant tolerance to salt stress. In the present study, we investigated the influence of AM fungi inoculation on various physiological, biochemical and nutritional aspects of pea grown under salt stress. The AM fungi inoculation successfully reduced the negative effects of salinity by improving the antioxidant enzyme system, a

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

Since male and female offspring may have different costs and benefits, parents may use sex ratio adjustment to increase their own fitness under different environmental conditions. Urban habitats provide poorer conditions for nestling development in many birds. Therefore, we investigated whether great tits (Parus major) produce different brood sex ratios in urban and natural habitats. We determined

In this paper, we report a remarkable population of the rare plant Sternbergia colchiciflora found along a busy road section in the downtown of county seat Veszprém (W-Hungary). The population contains at least 7000 individuals and spreads across fifteen grassy traffic islands. Regarding the position of individuals, their relative distance from the road/sidewalk within the traffic islands differed

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

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

European nature conservation has a strong focus on farmland harbouring threatened species that mainly co-occur with traditional agriculture shaped way before the green revolution. Increased land-use intensity in agriculture has caused an alarming decline in farmland biodiversity during the last century. How can a landscape perspective contribute to fostering our understanding on causes and consequences

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

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

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

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

Urbanization is one of the major causes of species loss and the homogenization of the world's flora. Our coarse-scale floristic mapping project of the largest south Transdanubian city, Pécs, is the first grid-based urban study in Hungary that reveals the current pattern of the vascular flora. Beyond the general description of the project, the species richness, the number of native, archaeophyte, neophyte

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)

In our study, we examined the movement of two wild boars marked with GPS/GSM transmitters in city of Budapest. We hypothesised that: the wild boars do not leave the urban area (H1); the wild boars prefer places that are less disturbed by people, and which are rich in potential hiding places (H2); and their home ranges would be smaller than that of wild boars living in non-urban environment (H3). Based

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
