(Fuzzy) Ideals of BN-Algebras.

The notions of an ideal and a fuzzy ideal in BN-algebras are introduced. The properties and characterizations of them are investigated. The concepts of normal ideals and normal congruences of a BN-algebra are also studied, the properties of them are displayed, and a one-to-one correspondence between them is presented.

Do toxic heavy metals affect antioxidant defense mechanisms in humans?

The aim of this study was to prove whether anthropogenic pollution affects antioxidant defense mechanisms such as superoxide dismutase (SOD) and catalase (CAT) activity, ferritin (FRT) concentration and total antioxidant status (TAS) in human serum. The study area involves polluted and salted environment (Kujawy region; northern-middle Poland) and Tuchola Forestry (unpolluted control area). We investigated 79 blood samples of volunteers from polluted area and 82 from the control in 2008 and 2009.

The Impact of Sex and Age on Serum Prohepcidin Concentration in Healthy Adults.

Introduction: Within the last 8 years, it has become evident that hepcidin has a diagnostic and therapeutic potential. Therefore, it is a great need to establish the reference interval for hepcidin and its precursor. The aim of this study was to assess the impact of age and sex on serum prohepcidin concentration in healthy adults.

Gender does not influence event-free survival in patients with ischaemic heart disease undergoing non-emergency coronary angiography. A single centre analysis.

Background: Although gender-related differences in cardiovascular risk in patients with acute coronary syndromes have been investigated several times in Poland, there are few data on the effects of gender on management of patients with stable ischaemic heart disease (IHD). In addition, available data on the prognosis in this condition in men and women are also scarce.

Aim: To assess gender-related differences in treatment and event-free survival in patients with IHD undergoing non-emergency coronary angiography.

Percutaneous coronary intervention triggers a systemic inflammatory response in patients treated for in-stent restenosis -- comparison with stable and unstable angina.

Objective And Design: It is believed that the magnitude of the systemic inflammatory response induced by percutaneous coronary intervention (PCI) impacts on the long-term outcomes in patients with stable angina (SA) and unstable angina (UA). We aimed to determine whether an inflammatory response appears in in-stent restenosis (ISR) patients undergoing balloon angioplasty and to assess its pattern and magnitude in relation to SA and UA subjects.

Subjects: 80 patients (59 with SA, 10 with UA, 11 with ISR) were enrolled into the prospective study.

Combined periprocedural evaluation of CRP and TNF-alpha enhances the prediction of clinical restenosis and major adverse cardiac events in patients undergoing percutaneous coronary interventions.

To assess the value of serial C-reactive protein (CRP), serum amyloid A (SAA), tumor necrosis factor-alpha (TNF-alpha) and interleukin-10 (IL-10) evaluation in the risk stratification in patients undergoing percutaneous coronary intervention. The study was designed as a prospective cohort trial with a 1-year follow-up. Eighty patients (70 with stable angina, 10 with unstable angina) were enrolled.

[Activation of fibrynolysis in children with chronic B or C hepatitis].

Unlabelled: Fibrinolysis is involved in numerous systemic processes, including inflammation and tissue remodeling. Up to date researchers focused on hemostasis problems in patients with cirrhosis. There are little data about fibrynolysis in patient with chronic viral hepatitis.

Endothelial dysfunction in acute coronary syndrome without ST segment elevation in the presence of Helicobacter pylori infection.

Background: Helicobacter pylori (H. pylori) infection is one of the most common chronic infections in humans. While a causative relationship between H.

Antibodies to Chlamydia pneumoniae and haemostatic factors in acute coronary syndrome without ST segment elevation.

Background: Various chronic infections, including Chlamydia pneumoniae (C. pneumoniae), are regarded as one of the possible factors which initiates, progresses and exacerbates atherosclerotic process. The relationship between C.

[Antibodies to tissue transglutaminase as marker of gluten-free diet maintenance in patients with coeliac disease].

The aim of the study was to assess the compatibility of IgA antiendomysium antibodies (IgAEmA) and IgA tissue transglutaminase antibodies (IgAtTG) in treated patients with coeliac disease and to estimate the value of the IgAtTG-ELISA as a marker of gluten-free diet maintenance. The study included 71 children and young adults (46 F, 25 M) aged from 6 years to 27 years, on the gluten-free diet (in some cases unrestricted) for at least 4 years because of coeliac disease diagnosed according to ESPGHAN criteria. Serum samples of all patients were examined simultaneously for IgAEmA titer by indirect immunofluorescence and IgAtTG level by ELISA test.
