Opis:
The least cardinal λ such that some (equivalently: every) compact group with weight α admits a dense, pseudocompact subgroup of cardinality λ is denoted by m(α). Clearly, $m(α) ≤ 2^α$. We show:
   Theorem 4.12. Let G be Abelian with |G| = γ. If either m(α) ≤ α and m$(α)≤ r_0 (G) ≤ γ ≤ 2^α$, or α > ω and $α^ω ≤ r_0(G) ≤ 2^α$, then G admits a pseudocompact group topology of weight α.
 Theorem 4.15. Every connected, pseudocompact Abelian group G with wG = α ≥ ω satisfies $r_0(G) ≥ m(α)$.
 Theorem 5.2(b). If G is divisible Abelian with $2^{r_{0}(G)} ≤ γ$, then G admits at most $2^γ$-many pseudocompact group topologies.
 Theorem 6.2. Let $β = α^ω$ or $β = 2^α$ with β ≥ α, and let $β ≤ γ < κ ≤ 2^β$. Then both $⊕_γℚ$ and the free Abelian group on γ-many generators admit exactly $2^κ$-many pseudocompact group topologies of weight κ. Of these, some $κ^+$-many form a chain and some $2^κ$-many form an anti-chain.

Opis:
The problem of estimating the number, n, of trials, given a sequence of k independent success counts obtained by replicating the n-trial experiment is reconsidered in this paper. In contrast to existing methods it is assumed here that more information than usual is available: not only the numbers of successes are given but also the number of pairs of consecutive successes. This assumption is realistic in a class of problems of spatial statistics. There typically k = 1, in which case the classical estimators cannot be used. The quality of the new estimator is analysed and, for k > 1, compared with that of a classical n-estimator. The theoretical basis for this is the distribution of the number of success pairs in Bernoulli trials, which can be determined by an elementary Markov chain argument.

Opis:
Let us consider two independent renewal processes generated by appropriate sequences of life times. We say that a renewal time is accepted if in the time between a signal and the preceding one, some signal of the second process occurs. Our purpose is to analyze the sequences of accepted renewals. For simplicity we consider continuous and discrete time separately. In the first case we mainly consider the renewal process rarefied by the Poisson process, in the second we analyze the process generated by the motion of draughtsmen moved by die tossing.

Opis:
In search for new markers of insulin-dependent diabetes (IDDM) susceptibility we studied the CATT tetranucleotide repeat in intron 1 of tyrosine hydroxylase (TH) gene on chromosome lip, the CA repeat at T-cell receptor a chain (TCRA) locus on chromosome 14q and two CA repeats at D10S211 and D10S213 loci in the chromosome 10 region containing glutamic acid decarboxylase (GAD2) gene. Alleles at these microsatellite loci were identified in a population of diabetic children and unrelated healthy controls originating from Wielkopolska, a midwestern region of Poland. We found significant association of certain alleles at TH, TCRA and D10S211 loci with diabetes in the population under study. On the contrary, none of the alleles at D10S213 locus was associated with the disease. Our findings indicate that typing of microsatellite markers may represent useful additional tool for identifying individuals at high risk of developing IDDM. Regarding loci on chromosome 10 our data and data published by other authors may suggest the extistence of two separate regions of association with IDDM susceptibility on this chromosome.

Opis:
The possibility of differentiation of L.monocytogenes from other Listeria species on the basis of hemolytic activity, the production of phosphatidylinositol-specific phospholipase C (PI-PLC) and the polymerase chain reaction (PCR) for the amplification of a DNA fragment of listeriolysine O (hly A) gene was compared. The screening of Listeria colonies for PI-PLC activity allowed to distinguish the pathogenic for humans L.monocytogenes bacteria from the majority of non-pathogenic Listeria spp. The amplification of DNA from Listeria lysates with two primers selected in area of the hly A gene made possible the differentiation of L.monocytogenes from other Listeria species, including hemolytic L.ivanovii and L.seeligeri bacteria as well as hemolytic or PI-PLC positive L.innocua strains.
Żywność zanieczyszczona Listeria monocytogenes byía notowana jako źródło zakażeń pokarmowych o charakterze epidemicznym w krajach w Europie i Ameryce Północnej. W związku z tym koniecznością się stalo opracowanie szybkich i czuîych testów wykrywania i identyfikacji pałeczek L. monocytogenes. W pracy porównano przydatność trzech testów do odróżniania chorobotwórczych dla człowieka bakterii L. monocytogenes od innych niepatogennych gatunków Listeria. Uzyskane wyniki wskazują, na niewielką przydatność oceny aktywności hemolitycznej dla różnicowania szczepów L. monocytogenes od niechorobotwórczych dla ludzi szczepów L. ivanovii, L. seeligeri oraz L. innocua. Różnicowanie takich szczepów w oparciu o aktywność fosfolipazy C fosfatydyloinozytolu wykazuje wyższą specyficzność. Cechę taką wykazywały wszystkie badane szczepy L. monocytogenes i tylko jeden szczep L. innocua spośród 9 niepatogennych szczepów Listeria. Amplifikacja fragmentu DNA w obrębie genu dla listeriolizyny O (hly A) L. monocytogenes, pozwoliła odróżnić wszystkie (18) szczepy L. monocytogenes od niepatogennych dla człowieka bakterii L. ivanovii, L. innocua, L. seeligeri, L. welshimeri oraz L. grayi. Trawienie produktu amplifikacji DNA enzymem Taq I, pozwoliło na wyodrębnienie dwóch typów w obrębie grupy badanych szczepów L. monocytogenes.

Opis:
The genetic similarity of three species: Septoria tritici, Stagonospora nodorum and Stagonospora avenae f. sp. triticea - important pathogens in many cereal production areas worldwide was assessed by random amplified polymorphic DNA (RAPD) assay. In preliminary research DNA of 14, 9, and 7 monopyenidios- pore isolates of S. nodorum, S. tritici, and S. a. tritícea, respectively, were amplified by PCR with four primers. Afterwards the research was focused on three mono- pyenidiospore isolates from each species studied. The isolates of each species selected for the study varied in pathogenicity and were diverse geographically. PCR with the set of 14 selected primers resulted in 99 different bands, ranged from 180 to 2500 base pairs in length. Most primers in PCR (especially RAD11, RAD31, RAD32, RAD33) revealed uniform bands for isolates of S. a. tritícea, that allow to identify this species among the others. The cluster analysis using Unweighed Pair-Group Method with Averaging (UPGMA) revealed interspecies disagreement among the isolates ranging from 32 to 53%. The intraspecies disagreement ranges were 17-20%, 38-43%, 42-44% for S. avenae f. sp. triticea, S. nodorum and S. tritici, respectively. Cluster analysis classified isolates into three homogeneous clusters. Each cluster grouped isolates of one species according to their current taxonomie ranks based on spore size, colony morphology and host ranges. In addition, two of the clusters represented by isolates of S. nodorum and S. a. tritícea were distinctly separated at a lower linkage distance from the third one comprising isolates of S. tritici. A slight inconsistency found in grouping some isolates indicates that such groupings should be done with caution. The present study indicates that the PCR- RAPD assay is of a potential use in taxonomy of Stagonospora spp. and Septoria tritici as well as in molecular identification of casual disease agents.

Opis:
We have analysed allele distribution at the highly polymorphic variable number of tandem repeats (VNTR) locus D1S80 (pMCT118) in the Polish population using the, polymerase chain reaction (PCR) technique. Characteristics of the D1S80 locus makes it a very useful marker for population genetic research, genetic linkage studies and forensic identification of individuals. During our routine application of the D1S80 marker to paternity testing in several cases of homozygosity detected by polyacrylamide gel electrophoresis, heteroduplex formation for alleles 18 and 24 was also observed. Direct sequencing of PCR products revealed that alleles 18 and 24 of locus D1S80 actually represent a mixture composed of different sequences. Our observations indicate that identification of some 18 and 24 VNTR alleles based only on size estimated in electrophoretic analyses could lead to errors in paternity testing and DNA profiling.

Opis:
Screening for molecular changes within the adenomatous polyposis coli (APC) gene, exons 11-14 and the 5’ half of exon 15, encompassing the mutation cluster region within exon 15, was performed in 30 patients with Familial Polyposis Coli (FAP). All patients were studied by heteroduplex analysis (HA) and single strand conformation polymorphism (SSCP) and molecular changes were found in 7 cases. Protein truncation test (PTT) has been performed in 17 cases in which mutations have not been found earlier, and shortening of protein product was noted in 2 cases. In three cases common deletion of 5 bp at codon 1309 and in one 5 bp deletion at codon 1061 were found. In other cases the molecular changes were demonstrated as heteroduplexes in exon 14 (1 patient), in segments E and F (one patient each) of exon 15, and in two cases the heteroduplexes were within the overlapping sequences of segments E/F and F/G of exon 15, respectively. In families where the molecular changes were found by HA, 7 persons at high risk for FAP were found and advised to undergo regular endoscopic examinations. In three persons at risk the transfer of mutation was excluded.
