Neutrophil count as the centerpiece in the joined association networks of inflammatory and cell damage markers, and neuroendocrine stress markers in patients with stable angina pectoris following stenting.

Objective: The primary aim of this study was to examine whether markers of cell damage and of the psycho-neuroendocrino-inflammatory/immune (PNI) system could be associated in patients with stable coronary artery disease (CAD) on the next day following percutaneous coronary intervention (PCI).

Materials And Methods: Blood samples of 23 patients (18 men and five women, mean age 62.9 ± 10.

The Monocyte-to-Lymphocyte Ratio Correlates with Psycho-Neuro-Inflammatory Factors in Patients with Stable Coronary Artery Disease.

Background: Psychosocial stress and depression have been recognized as major risk factors of coronary artery disease (CAD). Although monocytes are known to be key players in atherosclerosis, monocyte-based associations with psychoneuroendocrino-immuno-inflammatory (PNI) markers have not been widely investigated in stable CAD.

Objective: We examined associations between the monocyte-to-lymphocyte ratio (MLR) and key PNI markers in stable CAD.

ACTH- and cortisol-associated neutrophil modulation in coronary artery disease patients undergoing stent implantation.

Background: Psychosocial stress and activation of neutrophil granulocytes are increasingly recognized as major risk factors of coronary artery disease (CAD), but the possible relationship of these two factors in CAD patients is largely unexplored. Activation of neutrophils was reported to be associated with stenting; however, the issue of neutrophil state in connection with percutaneous coronary intervention (PCI) is incompletely understood from the aspect of stress and its hypothalamic-pituitary-adrenal axis (HPA) background. Thus, we aimed to study cortisol- and ACTH-associated changes in granulocyte activation in patients undergoing PCI.

Periosteal microcirculatory action of chronic estrogen supplementation in osteoporotic rats challenged with tourniquet ischemia.

Aims: Transient ischemia of osteoporotic bones during elective orthopedic surgery or fracture repair carries risks for serious complications, and estrogen loss or replacement has a potential to influence ischemia-reperfusion-induced inflammatory activation. To clarify this, we investigated the periosteal inflammatory changes in a clinically relevant time frame in ovariectomized rats, an experimental model of postmenopausal bone loss. Furthermore, the effects of chronic estrogen supplementation on the postischemic local and systemic inflammatory reactions were assessed.

Ischemic limb preconditioning downregulates systemic inflammatory activation.

We examined local and systemic antiinflammatory consequences of ischemic preconditioning (IPC) in a rat model of limb ischemia-reperfusion (I-R) by characterizing the leukocyte-endothelial interactions in the periosteum and the expression of adhesion molecules playing a role in leukocyte-mediated inflammatory processes. IPC induction (2 cycles of 10 min of complete limb ischemia and 10 min of reperfusion) was followed by 60 min of ischemia/180 min of reperfusion or sham-operation. Data were compared with those on animals subjected to I-R and sham-operation.

Effects of colloid solutions on ischemia-reperfusion-induced periosteal microcirculatory and inflammatory reactions: comparison of dextran, gelatin, and hydroxyethyl starch.

Objective: To compare the microhemodynamics and possible anti-inflammatory reactions of colloid resuscitation with 4% gelatin, 6% dextran, or 6% hydroxyethyl starch 130/0.4 solutions.

Design And Setting: A randomized control in vivo animal study in a university research laboratory.

Granulocyte activation in humans is modulated by psychological stress and relaxation.

Our aim was to study the possible relationship between psychological stress and granulocyte activation primarily in healthy students during an examination period (n = 11) and also in chronically anxious patients (n = 15). We employed cell surface markers: lactoferrin, L-selectin, alphaMbeta2-integrin and CD15s and flow cytometry to detect changes in the activation state of granulocytes, with the start of the stressed state in students at the beginning of an examination period, which was associated with elevated blood plasma cortisol level, and following relaxation hypnosis in both students, during their examination term, and patients. The ratios of all four types of marker-carrier granulocytes increased at the start of the examination period in students; an especially dramatic (ca.
