Distribution pattern, prevalence and intensity of parasitaemia of heteroxenous apicomplexan blood parasite Hemolivia mauritanica and its vector tick Hyalomma aegyptium have been studied in 264 tortoises (212 Testudo graeca and 52 T. horsfieldii) throughout the Iranian territory. In T. graeca the highest prevalence and intensity of parasitaemia for H. mauritanica were recorded in the temperate mid...
The interaction between zinc and cadmium was studied in tomato leaves (Solanum lycopersicum), in a hydroponic medium. Ten-day-old seedlings were treated with 25 μM CdCl2 associated to different concentrations of ZnCl2 (10, 50, 100, and 150 μM). We first observed that seven days after the metallic exposure Zn supply clearly reduced Cd concentration in leaves and simultaneously increased Zn uptake....
On the basis of several preclinical and clinical studies, we have assumed that phytochemicals may play an important role in plasma lipid metabolism. The aim of this study was to evaluate the effects of dietary administered Chlorella pyrenoidosa, young barley and fruit peel polyphenols from Flavin7 on plasma lipid metabolism in breast cancer model in female rats. The phytopharmaceuticals were dietary...
The plant Jurinea cyanoides (L.) Reichenbach (Asteraceae), protected under the European Commission Directive on the conservation of natural habitats and of wild fauna and flora (92/43/EEC), is critically endangered in Central Europe. The centre of its continuous range of distribution is in Ukraine and in a part of European Russia. Natural isolated populations have refugial distribution in the Czech...
Floodplain forests are sensitive to changes within the surrounding environment and contain the most highly invaded habitats. The overall aim of this study was to characterise floristic composition of floodplain forest along two different riparian corridors. The studied river ecosystems were influenced by human disturbances, but they have historically different hydrological management practices (e...
To investigate the phylogenetic relationships among Elymus and related diploid genera, the genome donor of Elymus, and the evolutionary history of polyploid Elymus species, nuclear ribosomal internal transcribed spacer (ITS) sequences were analyzed for 10 Elymus species, together with 17 diploid taxa from 5 monogenomic genera. The phylogenetic analyses (Neighbor-Joining) supported two major clades...
Lead (Pb), a widespread contaminant in terrestrial landscape, is highly detrimental to plant and animal life. Specifically, Pb-contaminated soils cause a sharp decrease in crop productivity, thereby posing a serious risk to agriculture. A study was planned to investigate the toxic effect of Pb2+ (0, 16, 40 and 80 mg L−1) in the seedlings of maize (Zea mays), in terms of induced physiological and biochemical...
The genus Ledermuelleriopsis Willmann, 1952 is recorded for the first time in South America. Ledermuelleriopsis verricula is redescribed based on material from Rio de Janeiro, Brazil.
The last version of Red List was published already more than 10 years ago but the knowledge of the flora of Slovakia has substantially improved due to large-scale mapping projects and taxonomical research. Therefore an updated fifth edition of the Red List is presented in this paper. For evaluation, we accepted IUCN categories (ER, CR, EN, VU, NT, LC, DD, NA, NE) and criteria (A–D), which were used...
In this study, a keratinolytic protease gene (named as kerD) from Aspergillus niger was cloned. The full-length coding sequence of kerD consists of 1,251 bp and encodes a protein with 416 amino acid residues with a molecular mass of 43,831 Da. A DNA fragment encoding mature kerD without its signal sequence was inserted into the expression vector pET30a(+) and successfully expressed in Escherichia coli...
The influence of agricultural management form on the structure and the species diversity of ground beetle (Carabidae) assemblages was studied. The research was carried out in the vicinity of Očová village (Central Slovakia) in 2005–2006. Carabid beetles were pitfall-trapped in four pairs of plots with the same crop, but conventionally and nature-friendly managed. In total, 54,376 individuals of 68...
Effect of sucrose and its abscisic acid (ABA) dependence was studied for seed germination, growth and antioxidant related parameters in two wheat cultivars PBW343 (ABA-lesser sensitive) and C306 (ABA-higher sensitive) by using sucrose (Suc) with or without sodium tungstate (inhibitor for ABA biosynthesis) in culture medium. Exogenous Suc (at 1.5% and 3%) inhibited germination in both cultivars where...
The deleterious effects of soil salinity on biodiversity and agricultural productivity make it essential to devise strategies that would reduce its impact and expansion. For sustainable agriculture on dryland salinity affected areas, the use of native salt-tolerant plant species of economic value could provide a solution. In this work, the salinity tolerance potential of fifteen different Australian...
Diabetes mellitus (DM) is considered as a risk of cardiovascular diseases due to the expression of certain pathological factors, including hormones, such as serotonin. The aim of the current study was to evaluate the bridging role of serotonin between DM and cardiac valvulopathy via reactive oxygen species (ROS) generation. Eighty diabetic patients and 50 healthy individuals along with experimental...
A total of 152 halophilic bacteria were isolated from Yuncheng Salt Lake, China. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that thirty-four strains were related to the phylum Firmicutes and belonged to three families, Bacillaceae, Clostridiaceae and Staphylococcaceae. The other strains were identified as the members of Halomonadaceae and Idiomarinaceae, which belonged...
Parasitological studies were carried out on pulli (n = 20) collected on a breeding colony near the Włocławski Reservoir on the Vistula River (Central Poland). Larvae of the nematode Contracaecum rudolphii (mean intensity of infection 9.3) were detected in the stomachs of all chicks, with adult worms present in two chicks. Larvae of the nematode Porrocaecum ardeae (mean intensity 3.1), the tapeworm...
