Spatial, temporal, and vertical variability of nutrients in the Southeastern Black Sea.

In this study, the nutrient concentrations along the coastal region of the Southeastern Black Sea were evaluated based on temporal, spatial, and vertical distributions. The water samples were collected seasonally in 2013 from 432 depths covering 55 stations. The nutrient concentrations showed significant spatial and temporal variations that declined abruptly from shore to offshore.

Determinants of iatrogenic femoral pseudoaneurysm after cardiac catheterization or percutaneous coronary intervention via the femoral artery.

Objective: This study aimed to define the prevalence and predictors for pseudoaneurysm after coronary angiography, cardiac catheterization and percutaneous coronary interventions (PCIs) performed via the femoral artery.

Methods: The study included 8469 patients enrolled between January 2007 and December 2009 on whom cardiac catheterization, coronary and/or peripheral angiography and PCIs via the femoral artery were performed. All data, including clinical characteristics and complications, were obtained retrospectively from patient chart records.

The effects of successful percutaneous mitral balloon valvuloplasty on acute and intermediate term aortic stiffness.

Aim: The aim of this study was to evaluate the effects of percutaneous mitral balloon valvuloplasty (PMBV) on short- and intermediate-term aortic stiffness in patients with mitral stenosis.

Materials And Methods: This prospective study included 56 patients with critical mitral stenosis in normal sinus rhythm (68% female; mean age: 42 ± 11 years) and 37 healthy controls. Aortic stiffness was measured using transthoracic echocardiography before PMBV, and 24-48 hours and 1 year post procedure.

Comparison of serum levels of inflammatory markers and allelic variant of interleukin-6 in patients with acute coronary syndrome and stable angina pectoris.

Objectives: Although the relationship between atherosclerosis and inflammatory cells has been recognized in recent years, the effect of interleukin-6 (IL-6) genetic variants associated with atherosclerosis is still controversial. Therefore, we investigated the association between IL-6 polymorphism and levels of IL-6 in patients with coronary artery disease (CAD).

Methods: We conducted a case-control study on 294 unrelated participants who were referred to the cardiology department of the university hospital for coronary angiography because of suspected ischemic heart disease.
