Parkinson's disease (PD) affects ∼1-2% of the elderly population. Development of a neuroprotective therapy that may be initiated early in the course of the disease to retard/prevent disease progression is highly desirable. This study aimed to investigate prophylactic treatment with coenzyme Q10 (CoQ10) before paraquat (PQ) exposure, a herbicide known to increase the risk for PD, to attain neuroprotection. In addition, therapeutic intervention with CoQ10 in mice already exposed to PQ (24 h) might halt ongoing neurodegeneration and behavioural deterioration...

UbiA prenyltransferase domain containing 1 (UBIAD1) is closely associated with cardiovascular diseases. However, at the cellular level, little is known about how UBIAD1 is expressed and functions in cardiomyocyte hypertrophy. The aim of the present study was to investigate the expression and role of UBIAD1 in angiotensin II (Ang II)‑induced hypertrophy in AC16 cardiomyoblast cells. The loss‑of‑function approach was used to knock down UBIAD1 in vehicle‑ and Ang II‑stimulated AC16 cells. The levels of atrial natriuretic factor (ANF) and caspase-3 were measured and compared between vehicle‑ and Ang II‑treated AC16 cells pretreated with control siRNA or siRNA against UBIAD1...

BACKGROUND: Hypertension is one of the primary modifiable risk factors for cardiovascular disease. Adequate vitamin D (vit D) levels have been shown to reduce vascular smooth muscle contraction and to increase arterial compliance, which may be beneficial in hypertension. Further, coenzyme Q10 (COQ10) through its action to lower oxidative stress has been reported to have beneficial effects on hypertension and heart failure. This study examined the possible cardiac and renal protective effects of vit D and COQ10 both separately and in combination with an angiotensin II receptor blocker, valsartan (vals) in l-NAME hypertensive rats...

Our recent studies revealed that supplementation with the reduced form of coenzyme Q10 (CoQ10H2) inhibits oxidative stress and slows the process of aging in senescence-accelerated mice. CoQ10H2 inhibits adipocyte differentiation and regulates lipid metabolism. In the present study, we show that dietary supplementation with CoQ10H2 significantly reduced white adipose tissue content and improved the function of brown adipose tissue by regulating expression of lipid metabolism-related factors in KKAy mice, a model of obesity and type 2 diabetes...

Low-density lipoprotein cholesterol (LDL-C) reduction is associated with a significant decrease in mortality, and statins represent the most effective drugs to achieve this. However, side effects of statins are very common and may lead to treatment discontinuation. Nutraceuticals are a combination of natural components that have shown efficacy in lowering LDL-C concentration when used alone or in association with other agents in patients who are intolerant to high-dose statins. Our aim was to compare the efficacy and tolerability of low-dose statin (LDS) therapy versus combined therapy of LDS plus a nutraceutical combination containing red yeast rice, policosanol, berberine, folic acid, coenzyme Q10 and astaxanthin (Armolipid Plus) in high-risk patients...
