The terms microparticles (MPs) and microvesicles (MVs) refer to large extracellular vesicles (EVs) generated from a broad spectrum of cells upon its activation or death by apoptosis. The unique surface antigens of MPs/MVs allow for the identification of their cellular origin as well as its functional characterization. Two basic aspects of MP/MV fun...
Neurological injury is a frequent and important complication of coronary artery bypass grafting (CABG). Several risk factors for this type of sequela have been identified, among them aortic arch atherosclerosis. Our previous study indicated that atherosclerotic burden in coronary arteries may likewise predict postoperative neurological complication...
Iron is one of the most important microelements in the human body. It is a component of haemoglobin, which transports oxygen to all cells in the organism. It is also used in the synthesis of myelin, neurotrans-mitters, and DNA and transfers electrons in biochemical reactions. Iron is also responsible for regular development of the foetus’ central n...

The tissue factor (TF) – tissue factor pathway inhibitor (TFPI) axis plays a major role in hemostasis. Disorders of the coagulation system are commonly diagnosed with the help of screening tests such as prothrombin time (PT), activated partial thromboplastin time (aPTT), and plasma fibrinogen concentration (PFC). However, the effect of prebiotics o...

Background/aim:
It is believed that the amniotic fluid-derived TF, in the case of amniotic fluid embolism (AFE), contributes to acute disseminated intravascular coagulation (DIC) and obstetric shock in the mother. However, the role of amniotic fluid-derived contact phase coagulation factors that irrupt into the bloodstream simultaneously with TF i...
Iron is found in almost all foods, so dietary iron intake is related to energy intake. However, its availability for absorption is quite variable, and poor bioavailability is a major reason for the high prevalence of nutritional iron deficiency anaemia. Absorption occurs primarily in the proximal small intestine through mature enterocytes located a...
Unlabelled:
The mechanisms contributing to thromboembolic complications in children with acute lymphoblastic leukemia (ALL) are complex, but it is believed that two factors are of critical importance, i.e. increased thrombin generation and decreased antithrombotic potential of the blood plasma. We evaluated generation of thrombin in three periods...
Introduction and objective:
The clinical consequences of malnutrition are multi-directional and result in dysfunctions of the majority of internal organs and systems. The results of recent studies suggest that a significant role is played by malnutrition in pathophysiology of iron homeostasis disorders, but the underlying mechanism is unclear. The...

Iron is an essential element in human development. It is imperative for oxygen and electron transport and also for DNA and neurotransmitters synthesis. On the other hand, this metal is able to participate in Fenton's reaction that in turn leads to free radical damage. The most toxic fraction of iron - nontransferrin-bound iron and its part desferri...
Introduction:
The diagnosis of iron deficiency anemia (IDA) in the context of the anemia of chronic disease (ACD) in elderly patients is often difficult due to the existence of many disorders. Recent studies have shown that hepcidin measurement (combined with the existing diagnostic methods) may possibly help in the differential diagnosis of IDA a...

Obesity and overweight have become a global problem affecting not only high income countries but also developing countries. According to the World Health Organization (WHO) more than 1 billion adults are overweight and at least 300 million of them are obese. Experimental and clinical studies indicate that there is a relationship between iron metabo...
Hepcidin is a newly discovered iron metabolism regulator. It decreases iron absorption from the duodenal enterocytes and inhibits its release from the reticuloendothelial macrophages. The experiments on hepcidin and its precursor--prohepcidin seem very promising and underline the need to establish the reference intervals for these proteins and defi...
