Opis:
Od ponad dziesięciu lat Polska korzysta z pomocy Unii Europejskiej w procesie modernizacji gospodarki i dostosowania jej do warunków współpracy międzynarodowej w ramach przyszłego członkostwa w europejskiej wspólnocie. W ramach wspierania przemian gospodarczych w krajach kandydujących do członkostwa w Unii Europejskiej utworzono wiele programów pomocy. Pomoc ta nie zakończy się z chwilą przyjęcia nowych członków, lecz będzie kontynuowana w ramach programów poakcesyjnych. Polskie koleje również uczestniczą w realizacji tych ambitnych zadań.

Opis:
Three sediment cores (Loopsoo, Tihu, Prassi) from Hiiumaa Island (Estonia) were investigated using diatoms, lithological proxies, magnetic susceptibility, geochronological dates and incorporated with the previously studied Kõivasoo site, aiming to reconstruct the development of the island and shoreline changes during the Litorina Sea and the Limnea Sea. The highest level of the Litorina Sea shoreline near Kõivasoo is at 27.6 m a.s.l., and it occurred during the Initial Litorina Sea. Within the Litorina Sea transgression, 7800 cal yr BP, relative sea level reached 24.9 m a.s.l. at Kõivasoo, 24.1 m a.s.l. at Loopsoo, 23.6 m a.s.l. at Tihu, and 21.5 m a.s.l. at Prassi. Kõivasoo became isolated from the sea about 8500 cal yr BP, Loopsoo between 7100 and 6800 cal yr BP, Tihu around 4800 cal yr BP, and Prassi about 2500 cal yr BP. Presently gained data from Hiiumaa Island confirm that the Litorina Sea regressed consistently during the last 8000 years due to progressively declining isostatic rebound. The present study is also illustrated by 3-dimensional palaeogeographic maps of the Hiiumaa Island development.

Opis:
The paper presents Monte Carlo simulations carried out during the preparatory phase of the Cherenkov Telescope Array project. The aim of the project is to build the next generation observatory of very high energy gamma rays. During the preparatory phase there is a need to optimize and verify design concepts for various elements of the array. In this paper we describe the main components of the software being used for that purpose, their functions and requirements. Preliminary results of the optimization of the small telescope – one of the several kinds intended for the array, are presented.

Opis:
Introduction: Expression of Epo, a glycoprotein secreted by the fetal liver and the adult kidney in response to cellular hypoxia and its receptor have been described in human solid tumors, such as colon and breast cancer. Purpose: Since activation of Epo-EpoR signaling pathway in erythroid progenitor and precursor cells leads to promotion of proliferation and differentiation or prevention of programmed cell death through Bcl-xl and Bcl-2 it was of interest to investigate expression of Epo, EpoR, apoptosis regulator – Bax and marker of proliferating cells - Ki-67 and assess correlation between them, with regard to clinicopathological variables of colorectal cancer. Materials and methods: The correlations between expression of Epo, EpoR, Bax and Ki-67 in colorectal cancer were analyzed in regard to patient age, sex, primary localization, histopathological type, grading, staging and lymph node invasion. Statistical analyses were performed by using the Spearman rank correlation test applying a significance level of p<0,05. Results: Correlation between Bax and EpoR is positive and statistically significant at all groups of patients except group pT1+pT2. Positive correlation between Bax and Epo is statistically significant at following groups of patients: all patients, age 60, age >60, male, female , primary localization in rectum, primary localization in colon, adenocarcinoma, G2, G3. Statistical analysis revealed no significant correlations between expression of neither Ki-67 with Epo nor Ki-67 with EpoR in all groups of patients. Conclusions: Epo seems to be a pleiotropic cytokine, which can exert its biological effect on several cell types, including neoplastic cells. The effect of Epo-EpoR signaling can differ in various cells and conditions.

Opis:
Nowadays, Hepatitis B X interacting protein (HBXIP) is an object of scientists’ interest worldwide. It is a protein with significant involvement in the development of malignant tumors like breast or ovarian cancer. One of the most important functions of HBXIP is the regulation of cell proliferation, which is related to the progression of a cell cycle. Many studies provide the growing number of evidence that HBXIP plays various important roles, including the regulation of a cell cycle through complexes with survivin, belonging to the inhibitors of apoptosis and interactions with transcriptional factors like STAT4, SP1, TFIID or E2F1. It also has the influence on the promotion of tumor angiogenesis thanks to the association with VEGF and FGF8. Another important role of HBXIP is a reprogramming of glucose metabolism to conditions favorable to growing cancerous cells due to regulating the activation of SCO2 and PDHA1. Furthermore, it impacts on the complement-dependent cytotoxicity, also, HBXIP affects on lipid metabolism through disturbing of metabolic pathways of FAS. According to recent studies, HBXIP can be used as a prognostic biomarker in many tumors, including cervical cancer, ovarian cancer, and esophageal squamous cell carcinoma thanks to the high expression of this protein noted exclusively in these tumor tissues. What is even more interesting, it significantly correlates with clinical attributes like metastasis to lymph nodes or grading and in some cases can potentially be used as the indicator of prognosis of treatment effectiveness. The paper is review through main functions of HBXIP and its possible applications.

Opis:
Introduction: Colorectal cancer (CRC) is one of the most common cancers in Poland. The aim of this study was to investigate the clinical significance of absolute monocyte count, neutrophil-to-monocyte ratio (NMR) and monocytetolymphocyte ratio (MLR) in pre- and postoperative blood samples of patients with CRC. Materials and Methods: We retrospectively reviewed medical records of 160 patients diagnosed with CRC who underwent surgery. Blood samples were obtained within 3 days before and after the surgical treatment. Venous blood samples were also obtained from 42 healthy controls. Results: Pre- and postoperative NMR were significantly higher than healthy controls (p<0.0001; p<0.0001). Moreover, MLR in pre-and postoperative blood samples were higher than voluntaries (p<0.001; p<0.001). The area under the ROC curve for pre and postNMR showed that the parameter exhibits strong diagnostic power (1.000). Pre- and postMLR had moderate diagnostic power amount 0.751 and 0.746. There is also correlation between monocyte count in samples obtained before and after surgery and, lymph node metastasis and size of lymph node metastasis in both cases. PreNMR value was significantly associated with venous and lymphatic invasion and the presence of cancer deposits. PostNMR was found to correlate with presence of distant metastasis and cancer cell deposits (R=0.633, p<0.001; R=0.158, p=0.040). Moreover, preMLR value was correlated with only perineural invasion. Conclusions: Analyzed hematologic markers may be useful as simply obtained parameters, next to histopathological examination, that determine a systemic immune response

Opis:
Introduction: Colorectal cancer (CRC) is the third most common cancer worldwide. At every phase of cancer development, the inflammatory process has an important impact. Accurate assessment inflammatory cells in the tumour environment in conjunction with clinico-pathologic features can be a relevant prognostic or predictive parameter. Purpose: To analyse inflammatory cell infiltration in CRC tumour mass and correlate with chosen clinico-pathologic parameters. Materials and methods: The study group consisted of 160 patients (64 women, 96 men) diagnosed with colorectal cancer who underwent surgery. Tissue material obtained from routine histopathological diagnosis was stained with H&E and used to assess the type of inflammatory cells in the invasive front and centre of the tumour. Results were subjected to statistical analysis with the age and gender of patients, tumour localization, tumour growth and size, TNM stage, adenocarcinoma type, fibrosis, necrosis, metastasis and tumour invasion (by the Spearman’s correlation coefficient test). Results: The presence of neutrophils in the invasive front of tumour mass was associated with fibrosis and inflammatory cell infiltration in the invasive front of tumour. Macrophages in the invasive front of tumour were found to correlate with tumour growth (expanding and infiltrate). Macrophages and eosinophils were associated with inflammatory cell infiltration in the invasive front and in the centre of tumour. Conclusions: The type of inflammatory cells in the invasive front or centre of the tumour may be useful to prognoses clinical features of colorectal cancer
