Drugs mimicking natural beneficial mutations, including that for familial hypercholesterolemia (FH), might represent the future of hypolipidemic drug treatment. ⋯ Mimicking the beneficial naturally happening mutations in lipid metabolism pathways with biological drugs is probably the future of hypolipidemic drug treatment.

Accumulating evidence has indicated that formation and accumulation of advanced glycation end products (AGEs) progress under diabetic conditions, thereby contributing to the development and progression of various diabetes- and aging-related disorders, such as diabetic nephropathy, diabetic retinopathy, atherosclerotic cardiovascular disease, insulin resistance, cancer growth and metastasis, osteoporosis, and Alzheimer's disease. Modification of proteins, lipids and nucleic acids by AGEs alter their structural integrity and function, and evoke oxidative stress generation and inflammatory reactions through the interaction with a receptor for AGEs (RAGE), being involved in the above-mentioned devastating disorders. ⋯ Since aptamers can be easily generated and highly penetrated into various organs with a low risk of allergic reactions, they may be superior to antibodies for neutralizing and/or blocking target proteins or cell surface receptors. Therefore, in this review, we describe the therapeutic potential of DNA-aptamers raised against the AGE-RAGE axis in diabetes-associated complications, especially focusing on vascular complications of diabetes and cancer.

Recently, we identified the circadian rhythm protein Period 2 (PER2) in robust cardioprotection from myocardial ischemia (MI). Based on findings that perioperative MI is the most common major cardiovascular complication and that anesthetics can alter the expression of PER2, we hypothesized that an anesthesia mediated downregulation of PER2 could be detrimental if myocardial ischemia and reperfusion (IR) would occur. ⋯ We identified midazolam mediated downregulation of cardiac PER2 as an underlying mechanism for a deleterious effect of midazolam pretreatment in myocardial IR-injury. These findings highlight PER2 as a cardioprotective mechanism and suggest the PER2 enhancers nobiletin or tangeritin as a preventative therapy for myocardial IR-injury in the perioperative setting where midazolam pretreatment occurs frequently.

This systematic review and meta-analysis of Randomized Controlled Trials (RCTs) were conducted to determine the effects of coenzyme Q10 (CoQ10) supplementation on metabolic profiles of patients diagnosed with Chronic Kidney Disease (CKD). ⋯ Overall, the current meta-analysis demonstrated that CoQ10 supplementation significantly improved metabolic profile in patients with CKD by reducing total cholesterol, LDL-cholesterol, MDA and creatinine levels, yet it did not affect fasting glucose, insulin, HOMA-IR, and CRP concentrations.

Despite the proven efficacy of anti-thrombotic, lipid-lowering, anti-hypertensive therapies and lifestyle modification changes for secondary ischemic stroke prevention, the risk of recurrent stroke, coronary events and vascular death remains substantial even for patients treated with high rates of established secondary preventive medications. ⋯ Inflammatory pathways seem to be key mediators in the development of atherosclerotic process, atheromatous plaque destabilization and thromboembolism. Colchicine as a novel therapeutic agent could be a safe and effective inhibitor of the inflammation cascade in patients with extra- or intracranial atherosclerosis or arteriolosclerosis, resulting in reduced vascular events.
