BACKGROUND: The β-caryophyllene (BCP), a phytocannabinoid presents in various essential oils, demonstrated selective action on the CB2 endocannabinoid receptor and attracted considerable attention because of its several pharmacological activities. Despite this recognized potential, this hydrophobic compound is a volatile and acid-sensitive sesquiterpene that readily oxidizes when exposed to air, and has low bioavailability in oral formulations. Thus, the development of formulations that guarantee its stability and increase its bioavailability is a challenge for its use in the pharmaceutical field...

The issue of vitamin deficiency persists to be a major health issue worldwide despite the advancements in medicine. At the same time, the effect of marginal vitamin deficiency status on physiological processes is proven. However, general methods such as immune-enzyme and fluorescence analysis, microbiological assays, for example, have limitations in vitamin status assessment and are not able to reliably reflect personal vitamin demand. The potential usefulness of modern metabolomics methods in vitamin status assessment is described in this review...

Killer immunoglobulin-like receptors regulate the activation of natural killer cells through their interaction with human leucocyte antigens. Killer immunoglobulin-like receptors and human leucocyte antigens loci are highly polymorphic, and some their combinations have been found to protect against viral infections or to predispose to autoimmune disorders. In particular, some activating killer immunoglobulin-like receptors profiles may be detrimental in autoimmune pathogenesis, and specific killer immunoglobulin-like receptors genes may be particularly aggressive in the clearance of different microorganisms, protecting individuals in the control of a given pathogen...

The no-reflow phenomenon refers to the post-percutaneous coronary intervention condition in which, despite re-establishing epicardial coronary vessel patency, the flow to the previously ischemic myocardium is markedly reduced. When it does occur, it attenuates the beneficial effect of reperfusion therapy and substantial regions of the myocardium fail to receive adequate perfusion. The pathophysiology of this phenomenon is not completely understood. The possible mechanisms could be related to alterations in the microvascular circulation...

A hallmark of atherosclerosis is its complex pathogenesis, which is dependent on altered cholesterol metabolism and inflammation. Both arms of pathogenesis involve myeloid cells. Monocytes migrating into the arterial walls interact with modified low-density lipoprotein (LDL) particles, accumulate cholesterol and convert into foam cells, which promote plaque formation and also contribute to inflammation by producing pro-inflammatory cytokines. A number of studies characterized transcriptomics of macrophages following interaction with modified LDL, and revealed alteration of the expression of genes responsible for inflammatory response and cholesterol metabolism...

Disorders of the innate immune system and associated cytokine disturbances play an important role in atherosclerosis. Although both pro- and anti-inflammatory cytokines have been detected in human atherosclerotic lesions, quantitative data on their expression in early atherosclerotic lesions remains to be reported. We studied localization of a pro-inflammatory cytokine, tumor necrosis factor-α (TNFα), and anti-inflammatory chemokine, C-C motif chemokine ligand 18 (CCL18), in human aorta. The intensity of staining for TNFα and CCL18 in atherosclerotic lesions was higher than in uninvolved tissues...

Atrial fibrillation (AF) is a frequent cardiac arrhythmia. It is a common major cause of serious diseases and is an increasing health-care burden. AF is associated with an excess amount of reactive oxygen species. In this review, we summarize several possible reactive oxygen species pathways that induce AF based on atrial electrical and structural remodeling data. The sources and factors implicated in AF-related oxidative stress include NADPH oxidase activation, calcium overloading and mitochondrial damage, angiotensin system activation, nitric oxide synthase uncoupling, and xanthine oxidase activation-associated cardiovascular conditions...

BACKGROUND: The incidence and prevalence of diabetes mellitus are increasing globally at alarming rates. Cardiovascular and renal complications are the major cause of morbidity and mortality in patients with diabetes. Methylglyoxal (MG) - a highly reactive dicarbonyl compound - is increased in patients with diabetes and has been implicated to play a detrimental role in the etiology of cardiovascular and renal complications. Derived from glucose, MG binds to arginine and lysine residues in proteins, and the resultant end products serve as surrogate markers of MG generation in vivo...

Atrial fibrillation (AF) is the most common and significant cardiac arrhythmia in clinical practice, however the pathophysiological mechanism of AF has not been fully explained. At present, there are no available treatment options can target the underlying pathophysiological processes of AF. Research on improving management strategies for AF can start with a further understanding of the changes of cells in AF. Mitochondria play central roles in the function of cardiac myocytes and many of the pathophysiological processes implicated in AF are relative to mitochondrial function, including formation of reactive oxygen species (ROS), calcium homeostasis, and alterations of oxygen consumption...

For nearly a century, the adult heart was considered as a post-mitotic organ. The discovery of a resident cardiac stem cell (CSC) population in the heart has dramatically undermined this notion with the support of encouraging preclinical and clinical studies aiming to regenerate the damaged heart after a myocardial infarction (MI). There are two ways to obtain CSCs for transplantation: Allogeneic and autologous sources. Autologous cells may be obtained from the patients' own tissue. Obtaining cells from diseased patients may contain a risk for altered stem cell characteristics...
