OBJECTIVE: Low-density lipoprotein cholesterol (LDL-C) has been well known as the risk factor of coronary artery disease (CAD). However, the role of lipoprotein (a) [Lp(a)] in the development of CAD is of great interest but still controversial. Thus, we aim to explore the effect of Lp(a) on predicting the presence and severity of CAD in Chinese untreated patients, especially in combination with LDL-C. METHODS: We consecutively recruited 1,980 non-treated patients undergoing coronary angiography, among which 1,162 patients were diagnosed with CAD...

Soybeans and hops have been traditionally used as a natural estrogen replacement therapy and their major active ingredients, isoflavones and prenylflavanones, are known to have estrogenic/antiestrogenic effects depending on the target organ. However, their potential benefits are still subject to controversies. The present study investigated the dual effect of soy isoflavones plus hop prenylflavanones (Soy-Hop) on bone loss and metabolic dysfunction under estrogen deficient condition. Rats were sham-operated ( n = 10) or ovariectomized (OVX; n = 40) and then fed a high-fat diet (HFD) to develop hyperlipidemia in OVX rats within the experimental period of 8 weeks...

The pathological phenomenon of somatopause, noticeable in hypogonadal ageing subjects, is based on the growth hormone (GH) production and secretion decrease along with the fall in GH binding protein and insulin-like growth factor 1 (IGF-1) levels, causing different musculoskeletal, metabolic and mental issues. From the perspective of safety and efficacy, GH treatment is considered to be highly controversial, while some other therapeutic approaches (application of IGF-1, GH secretagogues, gonadal steroids, cholinesterase-inhibitors or various combinations) exhibit more or less pronounced weaknesses in this respect...

The prevalence of obesity-associated nonalcoholic fatty liver disease has significantly increased over the past decade and end stage liver disease secondary to nonalcoholic steatohepatitis has become one of the most common indications for liver transplantation. This both increases the demand for organs and decreases the availability of donor livers deemed suitable for transplantation. While in the past many steatotic livers were discarded due to concerns over enhanced susceptibility to ischemia reperfusion injury and organ failure, the discrepancy between supply and demand has resulted in increasing use of expanded criteria donor organs including steatotic livers...

Bexarotene is a pleiotropic molecule that has been proposed as an amyloid-β (Aβ)-lowering drug for the treatment of Alzheimer´s disease (AD). It acts by upregulation of an apolipoprotein E (apoE)-mediated Aβ clearance mechanism. However, whether or not bexarotene induces removal of Aβ plaques in mouse models of AD has been controversial. Here, we show by NMR and CD spectroscopy that bexarotene directly interacts with and stabilizes the transmembrane domain α-helix of the amyloid precursor protein (APP) in a region where cholesterol binds...

Contrary to the mainstream blood group systems, P1PK continues to puzzle and generate controversies over its molecular background. The P1PK system comprises three glycosphingolipid antigens: Pk, P1 and NOR, all synthesised by a glycosyltransferase called Gb3/CD77 synthase. The Pk antigen is present in most individuals, whereas P1 frequency is lesser and varies regionally, thus underlying two common phenotypes: P1, if the P1 antigen is present, and P2, when P1 is absent. Null and NOR phenotypes are extremely rare...

The relation between dyslipidemia and atrial fibrillation (AF) development is still controversial. To assess the impact of lipid profile on new-onset AF, we followed 51,020 primary-care hypertensive patients without AF at baseline. After a mean follow-up time of 3.5 years, AF occurred in 2,389 participants (4.7%). We evaluated the association between total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, and new-onset AF. In a Poisson regression model fully adjusted for common risk factors of AF, we found that 1...

The quality and quantity of high-density lipoprotein (HDL) in blood plasma are important for preventing coronary artery disease. ATP-binding cassette protein A1 (ABCA1) and apolipoprotein A-I (apoA-I) play essential roles in nascent HDL formation, but controversy persists regarding the mechanism by which nascent HDL is generated. In the "direct loading model", apoA-I acquires lipids directly from ABCA1 while it is bound to the transporter. By contrast, in the "indirect model", apoA-I acquires lipids from the specific membrane domains created by ABCA1...

Statins essentially are cholesterol-lowering drugs that are extensively prescribed for primary and secondary prevention of cardiovascular disease. Compelling evidence suggests that the beneficial effects of statins may not only be due to its ability to control cholesterol levels but also due to a pleiotropic cholesterol-independent anti-inflammatory, antioxidant, endothelial-protective and plaque-stabilizing activity. Along this line, statins may also exert acute and long-term effects on renal function. We present a narrative literature review that summarizes arguments in favor of or against the preventive and/or therapeutic use of statins in kidney-related diseases or complications...
