Abstract	There are several genetic studies of the grayling (Thymallus thymallus) in Central Europe, however, the phylogeography and genetic structure of the populations from some areas are still poorly recognized. The aim of this study was to determine the distribution of genetic diversity and the history of the postglacial migration of the species in Poland. Biological samples were collected in seven rivers and one fish farm. All specimens were genotyped at 12 microsatellite loci. Moreover, the sequence of ND5 and control region mtDNA gene was determined. We found clear differences in genetic diversity among the investigated population, with the lowest values found for the fish farm (Rutki) and intensively exploited river (Płytnica), and the highest for coastal and submontane rivers (Vistula, Wisłok, San). Phylogenetic analysis based on mtDNA suggests the presence of two postglacial colonization waves of grayling in Poland: (I) from the refugium of the Danube; (II) the Atlantic Basin. Currently, managing the populations on the European scale should involve stocking populations with the materials obtained from fish caught in the same rivers taking into account both environmental factors and rational angling. Stocking plans should consider local populations whose mixing will reduce the heterozygosity of the population without affecting the genetic pool.

Abstract	Purpose: Recent increase in incidence of meningiomas suggests the need to search for new risk factors. Leptin, a potentially pro-angiogenic and proliferative agent, could be a candidate for this role, as its expression correlates with body mass index (BMI). Because development of meningioma has also been linked to sex hormones, bisphenol A (BPA), a known xenoestrogen, can also be taken into consideration as a potential risk factor. The aim of this study was to determine plasma concentrations of both substances in patients with meningiomas and to match it to patients with gliomas - a group of brain tumors less hormone- and BMI-dependent. Materials & methods: Concentrations of BPA and leptin were measured in plasma of 24 patients with low grade meningioma and in 29 patients with glioma, using gas chromatography-mass spectrometry (GC-MS) and ELISA kits, respectively. The concentrations of both substances in patients with neoplasms were interpreted in relation to their concentration in healthy population, published in recent reports. Results: Free and conjugated BPA were present in both meningioma and glioma patients. Moreover, their concentrations far exceeded those reported in the healthy population. Nevertheless, the level of leptin revealed to be significantly higher in meningioma patients than in glioma patients. Conclusions: Occurrence of both meningioma and glioma may be accompanied by increased concentrations of leptin and BPA. Further large-scale studies are needed to clarify whether the presence of both substances may play a role in pathogenesis or influence clinical course in patients with brain neoplasms.

Abstract	The capercaillie (Tetrao urogallus) is one of Poland's most endangered bird species, with an estimated population of 380-500 individuals in four isolated areas. To study these natural populations in Poland further, more than 900 non-invasive genetic samples were collected, along with samples from 59 birds representing large, continuous populations in Sweden and Russia; and from two centres in Poland breeding capercaillie. Microsatellite polymorphism at nine loci was then analysed to estimate within-population genetic diversity and genetic differentiation among populations. The results confirmed that isolation of populations and recent decreases in their sizes have reduced genetic diversity among capercaillie in Poland, with all the country's natural populations found to be experiencing the genetic after-effects of demographic bottlenecks. The results of analyses of genetic differentiation and structure further suggest the presence of a 'lowland' cluster (encompassing birds of the Augustowska and Solska Primaeval Forests in Poland, and of Sweden and Russia), and a Carpathian cluster. Capercaillie from Sweden and Russia are also found to differ markedly. The Polish lowland populations seem more closely related to birds from Scandinavia. Our genetic analysis also indicates that the stocks at breeding centres are of a high genetic diversity effectively reflecting the origins of founder individuals, though identification of ancestry requires further study in the case of some birds. Overall, the results sustain the conclusion that the Polish populations of capercaillie from the Carpathians and the lowlands should be treated as independent Management Units (MUs). This is to say that the breeding lines associated with these two sources should be maintained separately at breeding centres. The high level of genetic differentiation of birds from the Solska Primaeval Forest suggests that this population should also be assigned the status of independent MU.

Abstract	The Black Grouse Tetrao tetrix populations in Europe have become fragmented and reduced in numbers. These processes affected genetic diversity of the species, altering patterns of gene flow and genetic structure. In Poland, the Black Grouse is one of the most endangered bird species, however very little is known about diversity of this native population, bordering on to the area of Europe in which the species maintains a continuous range. To complete the knowledge of genetic structure of European populations, we analysed microsatellite polymorphism in 97 native Polish birds, along with 39 introduced individuals, originating in Belarus and at a breeding centre in Poland, regarded as representing the gene pool from the north-eastern part of the country. The results confirmed that isolation of populations and recent decreases in their sizes have reduced genetic diversity in Poland's populations of the Black Grouse. The results also indicated the presence of two genetic groups in Poland, involving birds of the north-eastern part of the country and the Carpathians Foothills in a first group, and the population from the Sudetes (Izerskie and Karkonosze Mountains) in a second. We suggest that the conservation effort should treat these two groups as independent units. We also analysed a fragment of the mitochondrial Control Region (CRmtDNA). The comparisons of sequences obtained with data from other Eurasian populations indicate that populations of the Black Grouse in Poland should be included within a large Conservation Unit — the northern tetrix — which comprises birds from Eastern and Northern Europe.

Abstract	The two-spot ladybird Adalia bipunctata (Linnaeus, 1758) (Coleoptera: Coccinellidae) is a widely distributed generalist, feeding preferably on aphids. The species inhabits various environments, including anthropogenic landscape, where pollution and microclimate enables to attain very high numbers of favorite prey. Recently, the abundance of the two-spot ladybird has declined, mainly as an after-effect of invasion of the competing species — the harlequin ladybird Harmonia axyridis (Pallas, 1773). High phenotypic polymorphisms made the two-spot ladybird classic model for population genetic studies of Coccinellidea. However, studies investigating diversity of the species at DNA level have Coccinellidae been scarce. In our investigation we used microsatellite markers to characterize genetic diversity in the two-spot ladybird populations from different environments. We made an attempt to amplify 13 loci, identified previously in the genome of the species, however due to lack of amplification, monomorphisms and presence of the null alleles, the final set of six markers useful for analysis on a population level was obtained. Analyzing genotypes of 124 individuals, we confirmed high genetic diversity of the species, suggested previously by studies, applying allozymes and mitochondrial DNA. Also, microsatellites revealed weakly pronounced genetic structure in a large scale (localities separated by a distance of 500 kilometers). However, we found some indications (signs of the Wahlund effect) that gene flow could be disturbed among sites in diverse environments (rural, suburban and urban). Our data suggested that invasion of the harlequin ladybird has not yet affected populations of the two-spot in such extent to alter genetic diversity or genetic structure.

Abstract	Human-induced changes in the natural environment impact upon a wide variety of genetic processes at all levels of population structure. Insight into these processes is now achieved by analyses of genetic diversity allowing the past and present condition of populations to be assessed and compared. Given its severe fragmentation and small size, the population of the Capercaillie Tetrao urogallus in Poland can be regarded as especially prone to gene-pool alteration. Moreover, this is a region of Europe in which different genetic lineages of the Capercaillie may be present, ensuring that certain conservation decisions may be even more difficult than they otherwise would be. Bearing the above in mind, we decided to study polymorphism of the mitochondrial DNA Control Region (mtDNA CR) in remnant and extinct populations of the Capercaillie in Poland. The extinct population was represented by samples from birds hunted in the Lower Silesian Forest (SW Poland) between 1951–1962. We compared sequences obtained with data from the large, continuous population present in Russia and Scandinavia. Analysing 331 bp of mtDNA CR for 168 individuals, we identified 24 haplotypes, among which only 6 had not been reported previously in the species according to GenBank. Our data confirmed a previous suggestion regarding the genetic structure of the species in Poland, i.e. that birds from Augustów Forest (NE Poland) are related to Russian and Scandinavian populations, constituting a part of the lowland group within the boreal lineage. The Carpathian population is in turn confirmed as an independent genetic group within the boreal lineage, while specimens from the Solska Forest (SE Poland) prove to be highly differentiated from birds in other Polish populations; most likely because they derive from — or have been connected via gene flow with — birds present in the Balkans. Further genetic analysis is necessary to resolve this evolutionary relationship between Capercaillies from south-eastern Poland and those of the Balkans. Where practice is concerned, the overall advice is that three Conservation Units are to be recognised in Poland. In addition to those, the extinct population from the Lower Silesian Forest has been deemed part of the lowland group within the boreal lineage, albeit a distinctive one, given the possibility of gene exchange with Carpathian birds. We further suggest that some aspect of this extinct population's genetic diversity reflects an uncontrolled process of reintroduction taking place in the past.

Abstract	Purpose: We aimed to study brain tissue oxygenation during the period of controlled reduction of arterial blood pressure - a maneuver often used in extended endoscopic skull base surgery for bloodless operative field. Methods: Intracranial pressure, arterial blood pressure and the resultant cerebral perfusion pressure were measured during extended endoscopic skull base surgery in 5 patients with diagnosed tumors of the skull base and arterial hypertension. Simultaneously, in those patients, we measured partial pressure of oxygen in the brain parenchyma (PbtO Results: Values of PbtO Conclusion: Moderate reduction of arterial pressure, often used to obtain bloodless operative field during extended endoscopic skull base surgery, may in patients with the medical history of arterial hypertension be associated with critically low values of partial oxygen pressure in brain tissue.

Abstract	Small and isolated populations are prone to future extinctions and thus perceived as ‘living dead’. Although generally considered to be of low conservation value, their existence can still enhance species survival at the landscape scale through improving the connectivity of other populations and facilitating some (even if little) gene flow. We investigated the demography and genetic status of a tiny and highly isolated local population of Maculinea (= Phengaris) alcon near its distribution margin with the aim of identifying the features that allow it to persist. The study comprised intensive mark-recapture, surveys of Gentiana pneumonanthe foodplants and butterfly eggs laid on them, as well as genetic analyses. The population has been found to be characterised by low genetic diversity and estimated at only a few tens of individuals. The foodplant availability turned out to be the most obvious factor limiting M. alcon abundance. Nevertheless, the life expectancy of adult butterflies is fairly long, and their flight period very short, implying that most individuals occur within the same time window. Together with the relatively little protandry observed, i.e. almost synchronous emergence of males and females, this increases the chances of random mating among the individuals. Moreover, the butterflies move freely across the core habitat fragment. All things concerned, the effective population size is presumably not much lower than the recorded population size. Our findings provide guidelines for pinpointing those among ‘living dead’ populations that are likely to be the most persistent and thus worth conservation efforts aimed at preserving them.

Abstract	Objective: To analyze the expression of β-catenin and N-cadherin in large series of meningioma cases and to investigate their correlation with peritumoral brain edema (PTBE). Materials and methods: Study group consists of 154 patients diagnosed with intracranial meningioma divided into: low-grade (G1) and high-grade (G2 or G3) group. PTBE was graded into four groups (0, I, II, III) using Steinhoff classification. The expression of N-cadherin, β-catenin was analyzed and graded based on the positive ratio of immunoreactivity. The results were analyzed statistically. Results: 104 cases were low-grade and 50 high-grade meningiomas. PTBE was observed in 103(66.8 %) cases: 57 grade I, 44 grade II and 2 grade III. Positive N-cadherin expression was found only in the membrane of the neoplastic cells in 50(48.1%) cases of low-grade, and in 34(68%) of high-grade group. In low-grade meningioma, β-catenin expression was observed within the cytoplasm and nucleus in 54(51.9%) cases. In high-grade meningiomas, β-catenin expression was observed in 33(66%) tumors only within the nucleus. N-cadherin expression was observed in 36 cases with PTBE grade I, 28 with grade II and 2 with grade III. β-catenin expression was observed in 40 cases with PTBE grade I, 24 with grade II and 2 with grade III. The results were statistically significant. Conclusions: Significant N-cadherin expression especially in high-grade meningioma group was found. β-catenin expression was the most evident in the nucleus rather than in cytoplasm. The degree of PTBE correlated with the N-cadherin and β-catenin expression and was the most prominent in high-grade meningioma group.
