Zdeněk Rušavý, Michal Žourek
The diabetic diet is one of the pillars of diabetes treatment. The rapid development of knowledge relating to the treatment of diabetes also includes diet. The paper focuses on the importance of a diet in the treatment of type 2 diabetes and prevention of atherosclerosis. Its main goal is to assess the impact of a composition of macronutrients on individuals with type 2 diabetes. The paper is divided into several parts, each of which ends with a conclusion. The first part examines weight reduction. The diet aimed at a weight loss is effective, it can effectively prevent diabetes, it leads to improvements in glucose control and reduction of the risk factors for atherosclerosis, however it will not impact on cardiovascular morbidity and mortality until after more than 20 years...

Oxidation of atherogenic low-density lipoproteins (LDL) plays a key role in the pathogenesis of atherosclerosis. Oxidation stress and inflammation are closely interrelated and they can potentiate one another. In the subendothelial space of the arterial intima, monocytes/macrophages become activated and phagocyte oxidized LDL (oxLDL) via scavenger receptors. It has been demonstrated that oxLDL forms complex with plasma β2-glycoprotein I (β2GPI) and becomes autoantigenic triggering synthesis of specific antiphosholipid antibodies...

Systemic inflammation and localized macrophage infiltration have been implicated in cardiovascular pathologies, including coronary artery disease, carotid atherosclerosis, heart failure, obesity-associated heart dysfunction, and cardiac fibrosis. Inflammation induces macrophage infiltration and activation and release of cytokines and chemokines, causing tissue dysfunction by instigating a positive feedback loop that further propagates inflammation. Cytosolic adaptor caspase recruitment domain family, member 9 (CARD9) is a protein expressed primarily by dendritic cells, neutrophils, and macrophages, in which it mediates cytokine secretion...

RATIONALE: In the endothelium, insulin stimulates endothelial nitric oxide synthase (eNOS) to generate the anti-atherosclerotic signalling radical NO. Insulin resistant type 2 diabetes is associated with reduced NO availability and accelerated atherosclerosis. The effect of enhancing endothelial insulin sensitivity on NO availability is unclear. OBJECTIVE: To answer this question we generated a mouse with endothelial cell (EC)-specific over-expression of the human insulin receptor (hIRECO) using the Tie2 promoter-enhancer...

RATIONALE: Heart failure (HF) and atherosclerosis share the underlying mechanisms of chronic inflammation followed by fibrosis. A highly conserved microRNA (miR), miR-33 is considered as a potential therapeutic target for atherosclerosis because it regulates lipid metabolism and inflammation. However, the role of miR-33 in HF remains to be elucidated. OBJECTIVE: To clarify the role of miR-33 involved in HF. METHODS AND RESULTS: We first investigated the expression levels of miR-33a/b in human cardiac tissue samples with dilated cardiomyopathy...

Quercetin is a dietary flavonoid compound extracted from various plants, such as apple and onions. Previous studies have revealed its anti-inflammatory, anti-cancer, antioxidant and anti-apoptotic activities. This study investigated the ability of quercetin to inhibit high fructose feeding- or LPS-induced atherosclerosis through regulating oxidative stress, apoptosis and inflammation response in vivo and in vitro experiments. 50 and 100mg/kg quercetin were used in our study, showing significant inhibitory role in high fructose-induced atherosclerosis via reducing reactive oxygen species (ROS) levels, Caspase-3 activation, inflammatory cytokines releasing, the number of terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL)-positive cells and collagen contents as well as modulating apoptosis- and inflammation-related proteins expression...

Familial defective apolipoprotein B-100 (FDB) is an autosomal dominant genetic disorder of lipid metabolism associated with hyperlipidemia and elevated risk for atherosclerosis. FDB is caused by mutations in APOB reducing the binding affinity between apolipoprotein B-100 and the low-density lipoprotein receptor. Population studies suggest that approximately 0.1% of Northern Europeans and US Caucasians carries the R3500Q variant in APOB most commonly associated with FDB; in addition, the APOB R3500 W variant is known to make a significant contribution to familial hypercholesterolemia (FH) among East Asians...

BACKGROUND: Our previous study showed that height is inversely associated with the risk of stroke in middle-aged Japanese men, particularly in those with a low body mass index (BMI). Since height is regarded as a surrogate maker of childhood social and physical condition, while BMI may reflect primarily on the current physical condition, a detailed analysis of those with a lower BMI may elucidate the effects of childhood conditions. On the other hand, dyslipidemia is recognized as a prominent risk factor for cardiovascular disease...

A recent study showed that posterior circulation plaques have a greater capacity for positive remodeling in a non-Asian population. We aimed to investigate if the features of plaques in the middle cerebral artery (MCA) were different from those in the basilar artery (BA) in a northern Chinese population. We retrospectively analysed the records of 71 consecutive patients with acute ischemic stroke. All patients had at least one MCA or BA plaque with early or mild (<50% stenosis) atherosclerosis identified using vessel wall magnetic resonance imaging...

Hyperuricemia is strongly linked to cardiovascular complications including atherosclerosis and thrombosis. In individuals with hyperuricemia, needle-shaped monosodium urate crystals (nsMSU) frequently form within joints or urine, giving rise to gouty arthritis or renal calculi, respectively. These nsMSU are potent instigators of neutrophil extracellular trap (NET) formation. Little is known on the mechanism(s) that prevent nsMSU formation within hyperuricemic blood, which would potentially cause detrimental consequences for the host...

Cardiovascular diseases, as a result of atherosclerosis, are the leading cause of mortality in the world. Atherosclerosis used to be considered as a degenerative impairment of the artery wall. Nevertheless, it is presently rather regarded as an autoimmune process with the involvement of both innate and adaptive immunity. Recently, it was demonstrated that the cardiovascular risk is increased in autoimmune diseases.In the pathogenesis of atherosclerosis in chronic inflammatory diseases both traditional and non-traditional risk factors are important...
