RCAS1 is involved in generating the suppressive profile of the tumor microenvironment that helps cancer cells evade immune surveillance. The status of the cells surrounding the cancer nest may affect both the progression of the cancer and the development of metastases. In cases of ovarian cancer, a large number of patients do not respond to the applied(More)
OBJECTIVES To study the assessment of diagnostic value and clinical usefulness of the determination of homocysteine concentration in blood serum in cases of recurrent miscarriages and the relation between the concentration of homocysteine in blood serum and parameter values determining the Doppler blood flow in the uterine arteries. METHODS Homocysteine(More)
OBJECTIVES The aim of the project was the assessment of clinical usefulness of the determination of blood serum homocysteine concentration, folic acid and vitamin B12 in recurrent miscarriages. METHODS 30 non-pregnant women with recurrent miscarriages (examined group-I) and for 20 non-pregnant women without obstetric failures in medical history (control(More)
BACKGROUND Angiogenesis is a basic process that enables neoplasms to thrive. Microvessel density (MVD) evaluation is an accepted parameter for assessing the angiogenesis process within a tumor. The aim of the present study has been to assess the number of microcapillaries in both invasive ductal breast cancer with the presence of metastases in regional(More)
OBJECTIVE The aim of this study were to assess the levels of lipofuscin (parameter of oxidative stress), homocysteine (as a marker of vascular injury) and tissue specific antigen - TPS - (as a marker of cell proliferation) in relation to arterial pressure of pregnant woman. STUDY DESIGN Healthy pregnant women (n=18), women with mild 140/90=< RR<160/100(More)
BACKGROUND Adenomas have the highest potential or clinical value from among colonic polyps of developing into adenocarcinoma. The aims of this paper are: to establish criteria to identify the high risk group of patients in a group of patients with colonic polyps, to work out a simple scheme for follow-up care after endoscopic polypectomy, and to establish(More)
The idea we want to advocate is the rapid prototyping of mobile multi-platform applications in the form of vanilla spreadsheets based on spreadsheet formulas, data validation and conditional formatting for tasks like entering and validating data, computing results and generating reports. Spreadsheet software systems, available on all major desktop and(More)
OBJECTIVE The aim of the study is to asses blood plasma concentrations of S-100B protein and Tissue Polypeptide Antigen (TPA) in patients with confirmed ischemic stroke and to correlate these concentrations with stroke severity. METHODS S-100B protein and TPA blood plasma concentrations were determined in 47 patients with acute ischemic infarction and in(More)
