Abstract
Colorectal cancer (CRC) is the fourth most commonly diagnosed malignant condition in the world. Micro RNAs (miRNAs) as well as epithelial to mesenchymal transition (EMT) play an important role in the pathogenesis of CRC. We performed a comparative analysis of the expression of selected miRNA genes and EMT markers in bioptic samples from patients (n = 45) with primary CRC or metastatic (m)CRC to the regional lymph node using reverse transcription-quantitative PCR and IHC staining. Results: Out of all miRNA analyzed, the miR-17 expression was most significantly different and associated with lower risk of CRC spread to the lymph node. In addition, significant relationships were found between the tumor side localization and several miRNAs expressions (miR-9, miR-29b, miR-19a, miR-19b, miR-21, miR-106a, miR-20a and miR-17). In addition, of the examined EMT markers, only VEGFA expression correlated with tumor progression (tumor grade G2). In the examined set of patient samples and their matched healthy tissue, several specific molecular markers (miRNAs associated with EMT and tumor progression) were identified with a promising prognostic potential. Their further examination in larger patient cohorts is planned to validate the present data.

Abstract
The most common reason for ascending aorta resection is an aneurysm or dissection. Aortic dissection is a life-threatening condition in which an aneurysm is a crucial risk factor. The essential criteria for aneurysm resection include the diameter, genetic predisposition, and aortic valve disease. This study aimed to compare the histological findings in aneurysms and dissections and correlate them with clinical parameters to determine whether histopathological findings correspond with the current clinical approach. A total of 160 ascending aorta surgical specimens, separate or with an aortic valve, were collected and divided into four groups: aneurysm-tricuspid (n = 40; median 67 y), aneurysm-malformed (n = 68; median 50 y), dissection-tricuspid (n = 48; median 65.5 y), and dissection-malformed (n = 4; median 52.5 y). Male preponderance was observed in all groups; the youngest patients were in the aneurysm-malformed group. None of the specimens showed normal aortic histology. The most common finding in the aortic samples was medial degeneration, which was the most severe and most common in dissection. The mildest findings were found in the aneurysm-malformed group. Atherosclerosis was predominant and most severe in the aneurysm-tricuspid group, while only mild in both dissection groups, suggesting its protective effect against this complication. Chronic aortitis was the least common pathology, found only in the aneurysm-tricuspid group. The aortic valve was resected and examined simultaneously with the ascending aorta in 76 cases, most commonly in the aneurysm-malformed group (n = 53). Myxoid degeneration was the major finding in the tricuspid aortic valves, with calcifications in the malformed. Comparing the histopathological results with the clinical aspects, aneurysms with a malformed aortic valve seem to be managed appropriately, with the findings not reaching the severity as in patients with a tricuspid valve. In contrast, in patients with a tricuspid valve, there were more dissections than aneurysms, with a significant subset of aneurysms showing histological findings almost identical to those of dissections. Supported by histological findings, patients with a diseased ascending aorta and tricuspid aortic valve represent an underdiagnosed risk group that would benefit from earlier diagnosis and intervention to prevent dissection. There is a need to find a marker for dissection risk other than the aortic diameter.

Abstract
BACKGROUND Colorectal carcinoma is one of the most common malignancies in western countries. Among different approaches to its research, primary cancer cell lines can play an important role. AIM The main purposes of this study were: 1) to establish an effective and reproducible method of colorectal cancer cell isolation and cultivation from primary tumours and lymph node metastases and 2) to elucidate the biological features of the tumours favouring successful cell cultivation. MATERIALS AND METHODS The tumour cells were obtained from colectomy specimens. Primary tumour and lymph node metastasis tissue was used for establishing the tissue cultures. Colectomy samples were further processed for routine histopathological assessment: tumour grade, stage, angioinvasion and perineural spread were evaluated. Features of tissue culture cells were assessed using phase contrast microscopy and immune-histochemical techniques. WST-1 assay and X-CELLigence real time analysis were carried out for viability and proliferation testing before and after treatment with irinotecan and oxaliplatin. Molecular features of the tumour including K-RAS/B-RAF/N-RAS mutations were tested using allele-specific PCR. Results of the cultivation process were compared to the histopathological and molecular features of the tumours. RESULTS In total, we obtained 33 samples from the primary site of tumours and 20 samples from lymph node metastases; in total, 27 cell lines were successfully isolated. Morphologic features characteristic of tumour cells in primary cell lines and epithelial differentiation (positive for AE1/AE3 cytokeratin) were evaluated. Higher tumour stage, angioinvasion and presence of perineural spread in primary tumour correlated positively with successful cell isolation from lymph node metastasis. All samples tested were NRAS wild-type. No correlation was found between molecular phenotype and the cell culture features. A higher proliferation potential was observed in the primary tumour cells, whereas higher sensitivity to irinotecan was found in the lymph node metastatic cells. CONCLUSIONS Using mechanical dissociation, we successfully derived and cultivated CRC cells from primary tumours and lymph node metastases with success rate 3 % and 70% respectively. Primary tumour features favouring successful establishment of cell cultures were identified.

Abstract
In developed countries, calcific aortic stenosis (CAS) has become the most common acquired valvular disease. It is considered a for of atherosclerosis and, like the latter, of inflammatory origin. Majority of cases of CAS are classified etiologically as either senile ("degenerative")--developing on previously normal aortic valve with three cusps, or based on congenitally malformed--bicuspid aortic valve. Twenty-eight cases of CAS (18 of the senile type, 7 of the bicuspid valve type, and 3 of indeterminable type) were examined by means of histology and immunohistochemistry (CD31 for blood vessels; D2-40 for lymphatics). In the calcified cusps, blood vessels were present in all 28 cases, and lymphatics in 14 of them. Vascularization was associated with lymphocytic infiltrates in 24 cases. There was no difference in the pattern between the two types of CAS. The origin of the cusp vessels is discussed. Our finding in the calcified cusps of both blood and lymphatic vessels together with lymphocytic infiltrates supports the inflammatory theory of the CAS pathogenesis.
