Neopterin, cellular adhesion molecules and myeolperoxidase in patients with stable and unstable angina pectoris
Neopterin, cellular adhesion molecules and myeolperoxidase in patients with stable and unstable angina pectoris Recent data indicate that the serum level of neopterin, a marker of inflammation and immune modulator secreted by monocytes/macrophages, is elevated in patients with acute coronary syndrome (ACS) and seems to be a prognostic marker for major cardiovascular events. Soluble cellular adhesion molecules (sCAMs) and myeloperoxidase (MPO) levels are also related to ACS. The aim of the present study was to evaluate differences in serum levels of neopterin, sCAMs and MPO between coronary artery disease and metabolic syndrome (CAD-MetS) patients with stable and unstable angina pectoris (SA…
Relation of Endothelial Dysfunction and Adipokines Levels to Insulin Resistance in Metabolic Syndrome Patients
Relation of Endothelial Dysfunction and Adipokines Levels to Insulin Resistance in Metabolic Syndrome Patients Obese metabolic syndrome (MS) patients were categorised into three groups: 44 with type 2 diabetes mellitus (T2DM)(D); 20 with T2DM and coronary artery disease (CAD) (DC), and 26 with MS alone (M). Eighteen healthy subjects were selected as controls (C). Insulin resistance (IR) was assessed by HOMA-IR. Adiponectin, tumour necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), and interleukin-8 (IL-8) concentrations were measured by xMAP technology. Endothelin-1 (ET-1) was determined by ELISA. We used laser Doppler imaging for evaluating cut…
Vazodilatācijas intensitātes un insulīna rezistences rādītāju saistība ar endoteliālo (dis)funkciju raksturojošo signālmolekulu koncentrācijām hroniskiem smēķētājiem
ANOTĀCIJA Pētījuma mērķis ir noskaidrot smēķēšanas ierosināta iekaisuma un oksidatīvā stresa ietekmi uz insulīna rezistences un endotēlija disfunkcijas attīstību un to savstarpējo sakarību. Pētījumā piedalījās 128 dalībnieki (starp kuriem 52 personām konstatējām dislipidēmiju), kuriem tika noteiktas ar endotēlija funkcijām saistītu signālmolekulu seruma koncentrācijas, vazodilatācijas intensitāte ādas mikrocirkulācijā un insulīna rezistenci raksturojoši rādītāji. Rezultāti parādīja, ka smēķēšanas kumulatīvais efekts būtiski sekmē insulīna rezistences attīstību personām ar dislipidēmiju, bet smēķēšanas akūtais efekts caur iekaisuma signālmolekulām īslaicīgi samazina šūnu insulīna jutību neat…
