Opis:
Ellagic acid (EA) is a natural antioxidant, belonging to the group of polyphenolic compounds. It displays a broad spectrum of pro-health effects, ranging from the prevention of cancer to antiviral properties. It is present in many fruit from the rose family (Rosaceae): strawberries, raspberries, blackberries and walnuts as well as cranberries and grapes. The available literature states that the fruit of roses, in addition to their aesthetic and functional applications, also show therapeutic properties, which, among other things, are associated with a high content of polyphenols, including ellagic acid derivatives. The aim of this research was to determine the differences in the content of free ellagic acid in the fruit of selected rose species. The test material consisted of freeze-dried sublimation and ground fruit from the following species of roses: R. canina, R. moyesii, R. pendulina. The fruit was separated into two fractions: flesh and seeds. Quantitative analysis of free ellagic acid was carried out by spectrofluorimetry. The free EA was present both in the flesh and in the seeds of the studied species of roses. Its content in the mentioned fractions varied depending on the species. The flesh of R. pendulina was characterised by the highest level of EA in free form (247.72 μg·g–1 of dry weight). The seeds of R. moyesii proved to be the most abundant in free EA (105.69 μg·g–1 of dry weight).

Opis:
Mice received 5 ng of ricin 24 hours after infection (experiment I) or 1 ng of ricin twice, 24 hours and 17 days of infection (experiment II). Animals were killed in 7, 14, 21, 28, 35, 42 and 60 days after infection. In the jejunum and masseter muscle sections, CD4⁺ and CD8⁺ lymphocytes, mast cells and eosinophils were studied. Heavy suppression of CD8⁺ lymphocytes, strong eosinophils and less pronounced mast cells stimulation was observed in the jejunum of mice received ricin (experiment I). Worm expulsion in intestine was faster than in the control (opposite results in experiment II). The composition of cells infiltration in the muscle was in both experiments similar to the control, however, fewer Cn4⁺ lymphocytes were observed in larva capsule and there were fewer muscle larvae. Therefore CD8⁺ cells are believed to take part in restricting only the muscle stage of trichinellosis.

Opis:
In the course of trichinellosis in mice the numerous cells inside larval capsules were observed. Beginning on 14 day post infection (dpi) they were seen in about 7% of infected muscles fibers but at 21 dpi the percentage of capsules with the cells amounted to 77. In the next stage of infection the number of capsules containing cells continued to increase and reach almost 100% at 60 dpi. The identification of the cells was carried out by the indirect immunoenzymatic method using anti-CD4⁺, anti-CD8⁺ and anti-macrophage (Mac-1 antigen) monoclonal antibodies. In course of observation the level of CD4⁺ cells decreased from 11.3 to 0.7, of CD8⁺ from 17.7 to 3.0 and of macrophages from 71.0 to 23.1 %. The most numerous CD4⁺ cells were seen at 14 dpi while the CD8⁺ and macrophages at 21 dpi. Beginning on 28 dpi negatively reacting cells inside larval capsules were also observed. The number of these cells increased from 23.8 to 73.2% at 60 dpi and their identification requires further investigations. The role and the function of all these cells are discussed.

Opis:
The seeds of forest trees usually transfer numerous fungi species, including pathogens, facultative parasites and saprotrophs. The aim of the present work was to determine qualitative and quantitative composition of fungi inhabiting the seeds of 10 trees species i.e.: birch (Betula pendula Roth.), beech (Fagus sylvatica L.), red oak (Quercus rubra L.), common oak (Quercus robur L.), sycamore maple (Acer pseudoplatanus L.), black alder (Alnus glutinosa Gaerth.), fir (Abies alba Mill.), European larch (Larix decidua Mill.), pine (Pinus sylvestris L.) and spruce (Picea abies (L.) H. Karst). The seed samples were obtained courtesy of 5 forest districts located in the south−eastern Poland. Mycological analysis was performed in the years 2012−2013. Each time, the study included 100 surface−disinfected seeds of particular plant species. As a result of the study about 2000 colonies of fungi representing 26 genera and above 39 species were isolated. The most frequently occurring species were: Fusarium spp., Penicillium spp., Alternaria alternata, Cladosporium cladosporioides, Trichoderma koningii, Epicoccum nigrum, Phoma spp. and Cylindrocarpon destructans. Moreover Discula spp., Phyllosticta spp., Pyrenochaeta spp., Rhizoctonia solani, Alternaria consortiale were obtained only from the seeds of deciduous trees while Truncatella angustata and Sphareopsis sapinea exclusively from the seeds of coniferous trees. The genus Fusarium was represented by 8 species and among them F. avenaceum, F. oxysporum and F. sporotrichioides dominated. Moreover Penicillium spp., Epicoccum nigrum, Trichoderma koningii, Botrytis cinerea, Cladosporium cladosporioides, Chaetomium globosum and Trichothecium roseum were commonly isolated while the other species of fungi were present in smaller numbers. Isolation of numerous fungi species which may cause mold of sowing material, seedling blight as well as leaves and needles spot, indicates their big threat for seeds during storage and for plants in the initial period of growth in a nursery. The obtained results show that the seeds, besides the infected soil, are a very important source of infection for young plants.

Opis:
The Stajnia Cave is one of the most important archaeological sites due to the finds of the first remains of Neanderthals in Poland, and several tens of thousands of flint artefacts from the Middle Palaeolithic. Based on geological, geochemical, palaeobotanical, palaeozoological, archaeological and isotope analyses, coupled with absolute age determinations (OSL, U-Th and C14), 15 lithostratigraphic layers were distinguished and palaeoenvironmental conditions during the sedimentation of these beds were determined. The cave loams accumulated through weathering, aeolian and fluvial processes. Their age may be correlated with an interval from the Early Glacial to the Late Pleniglacial of the Visulian (Weichselian) Glaciation. Archaeological relics related to the Neanderthals have been discovered in layer D with an absolute age of about 52,000–45,000 years BP and correlated with MIS 3 – the Middle Plenivistulian (Interplenivistulian). Climate oscillations in the Vistulian are reflected by the type of the sediments and their physical-chemical features, allowing determining warmer interstadial and colder stadial periods. Generally, the climate was cold, characteristic of tundra areas with a typical vegetation and fauna, and with the mean temperature of the warmest month not exceeding 12°C. Based on multi-proxy studies it can be concluded that from layer E1 upwards, the climate conditions became progressively drier. At that time, the climate was cold with continental features enhancing tundra domination. This conclusion is confirmed by palaeontological investigations and the record of stable oxygen isotopes in the teeth of reindeer. The studies have also indicated seasonal migration of reindeer on the tundra that surrounded the cave. Probably, short-term slight climate warmings occurred during the Middle Plenivistulian (Interplenivistulian).
