Opis:
The aim of presented work was to identify of PCR amplifiedDNAfragments differentiating aluminium tolerant and sensitive forms of rye and to locate the markers on rye chromosomes. For identification of markers, the PCR system with semi-specific primers targeting intron-exon sequences of plant genes was applied. The modified method of bulked segregant analysis was used. The pooled DNAs of two or three F2 segregating populations were screened together with DNA of their parental inbred lines. Potential marker of tolerance gene was located on rye chromosomes using wheat/rye (Chinese Spring/Blanco) additional lines. The specific probes obtained from DNA fragments differentiating sensitive and tolerant forms of rye were hybridized to PCR amplified DNA fragments of sensitive and tolerant forms of rye and the set of wheat/rye addition lines. Independently of the method of digoxygenin labelling (primer extension or Taq polymerase reaction), the probes obtained showed similar hybridization patterns. The results of hybridisation of 21 probes prepared from 12 DNA fragments confirmed connection of selected DNA fragments with to aluminium tolerance or sensitivity. Most of these DNA fragments originated from tolerant forms of rye. Using this method it was possible to locate eight DNA fragments on rye chromosomes. Three DNA fragments hybridised to chromosome 4R, two DNA fragments to chromosome 6R and single DNA fragments to chromosomes 1R, 2R and 3R. Four DNA fragments indicating clear relationship with character studied were not located on particular chromosomes using this set of wheat/rye addition lines. Hybridisation of probes prepared from four DNA fragments revealed length polymorphism. Probes prepared from two DNA fragments were characterised as dominant markers. In other cases the type of marker (dominant/codominat) was not fully documented.

Opis:
Twelve DNA fragments amplified on templates of Triticum urartu, Aegilops speltoides and Aegilops squarrosa were separated, reamplified and used as digoxigenin-labelled probes. The species and genome specificity of probes was evaluated by Southern dot-blot hybridisation to Triticum durum, the donors of wheat genomes, rye and rye with introgressed wheat chromosome fragments. In comparison to labelled genomic DNA of T. durum, the probes obtained by labelling PCR-amplified fragments exhibited higher specificity to wheat genomes. Under the applied hybridisation conditions all probes showed different degree of cross-hybridisation to rye DNA. Some probes indicated quantitative difference in their specificity to wheat genomes, but generally the intensity of hybridisation to the genomes A, S and D was independent of the origin of an amplified fragment. Selected probes, used in dot-blot hybridisation system together with genomic DNA of T. durum, may increase the sensitivity of screening wheat chromosomal fragments introgressed to rye.

Opis:
Polysaccharides are macromolecular polymers that manifest ability toward the forming of fibres, film and coatings. Some of their specific properties like biodegradability and biocompatibility make them suitable for medical application. Chitin, chitosan and alginates are basic polymers mostly used in the preparation of medical biomaterials. In the Institute of Biopolymers and Chemical Fibres (IBWCh) multidirectional investigations are in full swing concerned with the use medical of polysaccharides and their various useful forms. The research includes amongst: multifunctional dressing materials, implants and other polysaccharide biomaterials.

Opis:
Investigations are presented in the preparation of composite dressing material based on two biopolymers -chitosan and sodium alginate with the addition of sulfanilamide as medication designed for the healing of bedsores. The dressing was prepared in the form of film. The biopolymers used in the construction of the film make the dressing biodegradable and resorbable in the wound’s environment. Mechanical properties of the film were tested: thickness, extension strength, tenacity and elongation at maximum stress The ability of the material to match the wound was examined, too, as well as the transmission of water vapor. Sulfanilamide as bacteriostatic agent was added to the prepared composites. Mechanical and sorption properties of the composite dressings with addition of the active substance depend largely on their composition. The sorption properties were tested before and after addition of the medication .The release of the medication is intricate and proceeds according to kinetics of first order. Susceptibility of the composite materials to hydrolytic and enzymatic degradation was assessed.

Opis:
A decrease in migration of tumor cells incubated with the investigated chitosan preparations was correlated with a decreased activity of MMP-2 and MMP-9 metalloproteinases, what significantly affected inhibition of tumor cell proliferation. In the investigations of the effects of various chitosan preparations on expression of PCNA, Akt and β-catenin in the normal human 184A1 cells and in breast carcinoma MCF7 cells evaluated at the protein level, significant differences in inhibition of expression of selected genes were noted in the tumor cells. Similarly as in the case of human cells, in mouse cells, the differences in expression of the investigated genes involved solely the Ehrlich carcinoma cells. In the presence of the investigated chitosan preparations, there was observed inhibition of expression of the N-cadherin, β-catenin, Akt and PCNA genes. In case of p21 protein, its level increased, similarly as in the human breast carcinoma cells, what may also be related to phosphorylation of the protein, its capture by the cytosol and prolonging its half-life as compared to the non-phosphorylated form. In case of the normal human 181A1 cells and mouse CRL 1636 cells, no significant alterations were noted in expression of the investigated genes in presence of the employed chitosan preparations.
