Knowledge about the three-dimensional fine structure of human heart, as a crucial vital organ of the body, is not only fascinating from the scientific or educational points of view, but has a very important clinical impact. Therefore, we decided to create a three-dimensional atlas of fine structure of the human heart. Tissue samples from ten human hearts were rinsed in phosphate-buffer solution, fixed...
The current study was carried out to check the influence of the gradient saline (0, 50, 150, 200, 250 and 300 mM NaCl) on Astragalus gombiformis Pomel. plants grown in pots in greenhouse conditions. The results demonstrated that salt levels above 50 mM substantially reduced the biomass accumulation in both roots and especially in shoots. Similarly, higher salinity (100–300 mM NaCl) resulted significant...
Increased anthropogenic environmental pollution, one of the serious threats associated with rapid industrial/ economic development leads to enhanced release of SOX and NOX in the troposphere which later combined with moisture and results in acid rain (AR). Recurrence of AR leads an array of alterations in plants that includes inhibited seed germination, growth and productivity, biomass accumulation,...
The myoelectrical activity of ovine gallbladder is incompletely recognized. Accordingly, each of five rams was fitted with six small intestinal and three gallbladder electrodes. The strain gauge force transducer was also mounted near the gallbladder fundic electrode. In two series of chronic experiments the electromyographical and mechanical recordings were conducted during 5–7 h in fasted or non-fasted...
The impacts of year-round nocturnal warming or late spring rain exclusion on three plant functional types were studied in a plot-scale climate simulation experiment in a semiarid sand forest-steppe of Central Hungary. Ecophysiological traits were followed through six years for the C3 bunch grass Festuca vaginata, the spreading C4 grass Cynodon dactylon and shrub-sized root suckers of Populus alba...
The Piabina genus was allocated in Stervadiinae subfamily after staying for years as an uncertain group in Characidae. Few cytogenetic studies are described in the literature for Piabina argentea, thus new analyzes in other populations are important to understanding of the chromosomal dynamics of them. The aim of this paper was to analyze the chromosomes of P. argentea from Corumbataí River basin...
Transportation infrastructure may be the most important driver of social and economic development, but it is a major cause of environmental change in landscapes. The main objective of this paper is to report road edge effects on isopods of Hungarian highway verges. We examined the isopod diversity along five highways (M0, M1, M3, M5, M7) while accounting for road edge proximity and the adjacent areas...
A laboratory survey was done to study both day length and male effect on the reproduction of Porcellio laevis Latreille, 1804. Specimens were maintained in six climatic chambers at different photoperiods [Light:Dark (LD) 0:24, 4:20, 8: 16, 12: 12, 14: 10, 16: 8 and 24: 0] at constant temperature of 20 ± 1°C. The characterization of photoperiodic induction on the onset of reproduction in P. laevis...
In 2017, a new non-indigenous crayfish species was found established in Europe. The captured individuals were identified as an orange morph of the Mexican dwarf crayfish Cambarellus patzcuarensis Villalobos, 1943. Fifteen adults (including three ovigerous females) and 26 juveniles were collected in a thermal pond in Budapest, Hungary. Two additional adults were caught below the pond’s outflow in the...
The trophic relations of the red-crowned crane in Zhalong wetland, northeastern China may significantly be altered due to the rapid decrease in accessible food resources. To confirm this hypothesis, we determined the trophic status of this vulnerable species by using stable isotope (carbon (δ13C) and nitrogen (δ15N) methods. The δ13Cand 15Nsignatures in the red-crowned crane species were in the range...
The paper describes the isolation and characterization of a novel pelagic bacterial strain capable of hepatotoxic microcystin (MC) degradation. From a total of 24 bacterial strains isolated from water samples collected during the cyanobacteria blooming period in Jeziorsko reservoir, Poland, only the strain JEZ-8L was found to completely degrade microcystin-LR (MC-LR). The strain JEZ-8L was found to...
Rhynchotalona falcata (G.O. Sars, 1861) was found in the plankton of a gravel pit located in the lowlands of Slovakia. This is the first record of this taxon for Slovakia, although it is widely distributed in Western Europe. We do not know to date, whether it is a rare, native species of Slovakian fauna, or accidentally introduced one from north-west regions of Europe. Some notes on its biology and...
The sampling surveys were conducted in the northern Iran, using several Malaise traps, during 2010–2011. A single specimen of a rare root aphid parasitoid, Aclitus obscuripennis Förster, 1862 (Hym.: Braconidae: Aphidiinae) was identified among the collected specimens. This is the first record of the genus Aclitus in Iran and western Asian area. Aclitus obscuripennis is re-described and illustrated...
The diversity relationship between tree and herb layer has often been investigated, but the results are contradictory. Moreover, few studies of deciduous European species have been conducted to date in natural or near-natural forests, while such studies in old-growth forest with considerable co-dominance of oak are missing.In one of the best preserved natural European beech-sessile oak forests (Runcu-Grosi...
A total of 60 endophytic fungal strains were isolated and screened for their producing-ability of 6-pentyl-α-pyrone (6PP), which has a coconut-like aroma. Of these isolated strains, four strains of Trichoderma koningii Oudemans were positive for 6PP production. Agar well diffusion assay was employed to test the antimicrobial activity of 6PP against 22 microbial strains. Although 6PP showed no antibacterial...
ADP-glucose pyrophosphorylase (AGP) consists of two large (AGP-L) and two small (AGP-S) subunits; it regulates the limiting step in the biosynthesis of starch. Here, we isolated the full-length cDNA sequence of the AGP-S gene (designed as Agp1) from wheat and whole genomic sequences from relatives of wheat. The coding region of Agp1 ranged from 5948 bp to 7666 bp and contained 9 exons and 8 introns...
The aim of this work was the isolation of endophytic cacti fungi producer of pigments. Twenty different endophytic fungi were isolated from Ferocactus latispinus using a standard method. One of these was an orange pigment producer and was identified with molecular biology techniques amplifying internal transcribe spacer region. The fungus identified was Fusarium solani; it is a producer of polyketides...
Exposure of Arabidopsis leaves to cadmium (Cd) stress led to an increase in the level of extracellular ATP (eATP). And, Cd stress also caused significant increases in lipid peroxidation and the activities of lipoxygenase (LOX) and antioxidant enzymes, including superoxide dismutase (SOD), peroxidase (POX), and catalase (CAT). Treatment of Arabidopsis leaves with β,γ-methyleneadenosine 5’-triphosphate...
