Exposure to ambient air pollution influences cardiovascular (CV) morbidity and mortality. The differential effects of changing particulate or gaseous air pollution on endothelial function in young healthy individuals remain unclear. The aim of this study was to evaluate the relationships between exposures to different pollutants and vascular function in a group of 39 young (33±11 years old) subjects with low CV risk.

Background: Systemic inflammation may cause endothelial activation, mediate local inflammation, and accelerate progression of atherosclerosis. We examined whether the levels of circulating inflammatory cytokines reflect local vascular inflammation and oxidative stress in two types of human arteries.

Methods: Human internal mammary artery (IMA) was obtained in 69 patients undergoing coronary artery bypass graft (CABG) surgery and left anterior descending (LAD) artery was obtained in 17 patients undergoing heart transplantation (HTx).

Erythromycin (EA) is an antibiotic whose concentration in water and wastewater has been reported to be above the standard levels. Since the methods used so far to remove EA from aquatic environments have not been effective, the development of effective methods for EA removal is necessary. In the present study, fly ash (FA)-based zeolite materials, which have not been investigated as EA sorbents before, were used.

Article Synopsis
  • Abdominal Aortic Aneurysm (AAA) is linked to high cardiovascular mortality, with chronic inflammation and changes in blood vessel behavior contributing to its progression.
  • Perivascular adipose tissue (PVAT) plays a dual role, helping to maintain vascular health but also potentially promoting disease when inflamed.
  • This study found that T cells, especially activated CD4 T cells, are the dominant immune cells in AAA, particularly in PVAT, and their presence correlates with the size of the aneurysm, suggesting PVAT's significant role in AAA-related inflammation.

Introduction: Difficult-to-treat rheumatoid arthritis (RA) is a significant clinical problem despite no clear definition. We aimed to provide clinical characteristics and associated comorbidities of RA patients in relation to disease control.

Methods: RA characteristics and physician-recorded comorbidities were analyzed in a sample of 1937 RA patients.

Introduction: There are no reliable data regarding the prevalence of rheumatoid arthritis (RA) in Poland.

Material And Methods: The first stage was a face-to-face survey on a nationwide representative sample of 3000 people, which identified respondents with a physician-confirmed diagnosis of RA. The second stage was a survey of RA patients, which characterized the disease course and treatment.

Ankylosing spondylitis (AS) is associated with high cardiovascular morbidity and mortality. Recent studies indicate that microvascular dysfunction may underlie cardiovascular risk in AS. We hypothesized, that microvascular morphology and dysfunction is linked to AS activity and is modifiable by TNF-α inhibitor (TNFi) treatment.

The aim of the study was to assess the content, distribution, soil binding capacity, and ecological risk of cadmium and lead in the soils of Malopolska (South Poland). The investigation of 320 soil samples from differently used land (grassland, arable land, forest, wasteland) revealed a very high variation in the metal content in the soils. The pollution of soils with cadmium and lead is moderate.

The aims of the study were to investigate the concentration, sources and ecological risk of PAHs (polycyclic aromatic hydrocarbons) in bottom sediments collected from nine reservoirs located in south-eastern Poland. The concentration of ∑PAHs in sediments ranged from 150 to 33,900 μg kg. The total PAH concentration in the bottom sediments was arranged in the following order: Rybnik > Rzeszów > Brzóza Królewska > Brzóza Stadnicka > Besko > Chechło > Ożanna > Głuchów > Narożniki.

The aims of this study were to investigate zinc content in the studied soils; evaluate the efficiency of geostatistics in presenting spatial variability of zinc in the soils; assess bioavailable forms of zinc in the soils and to assess soil-zinc binding ability; and to estimate the potential ecological risk of zinc in soils. The study was conducted in southern Poland, in the Malopolska Province. This area is characterized by a great diversity of geological structures and types of land use and intensity of industrial development.

Endothelial dysfunction and inflammation are key mechanisms of vascular disease. We hypothesised that heterogeneity of monocyte subpopulations may be related to the development of vascular dysfunction in coronary artery disease (CAD). Therefore, we examined the relationships between monocyte subsets (CD14CD16 "classical - Mon1", CD14CD16 "intermediate - Mon2" and CD14CD16 "nonclassical - Mon3"), endothelial function and risk factor profiles in 130 patients with CAD undergoing coronary artery bypass grafting.

Article Synopsis
  • A study was conducted to create a low-cost method for predicting drug resistance in cancer patients using tumor tissue samples.
  • Tumor cells from 12 female patients were cultured and exposed to various chemotherapy drugs to assess their effects on cell growth and apoptosis.
  • The findings indicated that half of the tumor cells were resistant to single drugs, but some combinations showed positive effects, suggesting that personal cell cultures could help tailor chemotherapy approaches and provide insights into drug efficacy.

The maintenance of blood vessel homeostasis is closely associated with Reactive Oxygen and Nitrogen Species (ROS and RNS) production in the blood vessel wall. The main molecules taking part in this process are nitric oxide (NO), superoxide anion (O2*-), hydrogen peroxide (H2O2) and their derivatives. The production of these factors occurs in health and disease, however the increased ROS release is often referred to as oxidative stress.

Article Synopsis
  • The study aimed to assess the quality of life (QOL) in women with ovarian cancer at different stages: before surgery and three to six months after surgery.
  • Researchers conducted interviews with 93 patients using two specific questionnaires over a period from 2006 to 2008.
  • Results indicated improvements in global health, emotional functioning, and specific symptoms like pain and nausea after treatment, emphasizing the importance of regularly evaluating QOL in ovarian cancer patients.

Aims And Objectives: To evaluate the quality of life in hospitalised patients with cervical cancer treated by radiation therapy.

Background: Aside from clinical variables, the quality of life should be considered in the planning and monitoring of the therapeutic process in patients with cancer. Although it is widely known that this parameter can have a considerable impact on the therapeutic outcome, it is not routinely screened in oncological patients.

Intraluminal thrombus formation in aortic abdominal aneurysms (AAA) is associated with adverse clinical prognosis. Interplay between coagulation and inflammation, characterised by leukocyte infiltration and cytokine production, has been implicated in AAA thrombus formation. We studied leukocyte (CD45+) content by flow cytometry in AAA thrombi from 27 patients undergoing surgical repair.

The aim of the study was to investigate the prognostic significance of selected clinico-morphological parameters including Ki-67 antigen expression and microvessel density. The data of 122 patients with squamous cell carcinoma, FIGO stages IB-IIIB and treated with radiochemotherapy and brachytherapy were studied. Significant prognostic factors for disease-free survival in univariate analysis were the FIGO stage and the presence of atypical mitoses in carcinoma cells.

Hereditary ovarian cancer is often believed to be as a distinct disease. It is diagnosed earlier than its sporadic type; serous subtypes and more advanced stages are usually observed. Mutations of genes like BRCA1, BRCA2, MMR (MLH1, MSH2, PMS1, PMS2) are strictly associated with the heredity of ovarian and also breast cancer.

Introduction: Germinal mutations of BRCA1/BRCA2 genes are one of the important reasons of breast and ovarian cancer development. The prevalence of BRCA1 mutations in Polish population is relatively frequent, particularly among families at high-risk of breast and/or ovarian cancer. Moreover, the presence of "founder effect" is characteristic for those families.
