PURPOSE OF REVIEW: To discuss recent advances in research focused on intestinal lipid handling. RECENT FINDINGS: An important strategy in reducing atherosclerosis and risk of cardiovascular events is to increase the rate of reverse cholesterol transport, including its final step; cholesterol excretion from the body. The rate of removal is determined by a complex interplay between the factors involved in regulation of intestinal cholesterol absorption. One of these factors is a process known as transintestinal cholesterol excretion...

Virgin olive oil (VOO) constitutes the main source of fat in the Mediterranean diet. VOO is rich in oleic acid, displaying health-promoting properties, but also contains minor bioactive components, especially phenolic compounds. Hydroxytyrosol (HT), the main polyphenol of olive oil, has been reported to be the most bioactive component. This review aims to compile the results of clinical, animal and cell culture studies evaluating the effects of HT on the features of Metabolic Syndrome (MetS) (body weight/adiposity, dyslipidemia, hypertension, and hyperglycemia/insulin resistance) and associated complications (oxidative stress and inflammation)...

The main risk factors in ischemic heart diseases, including myocardial infarction, are hypertension, dyslipidemia, diabetes, obesity and smoking. The incidence of ischemic heart disease in Japan has been lower than that in Western countries because of differences in lifestyle and the anatomy of the coronary arteries, but the situation has been changing recently because of the westernization of lifestyle. Cardiovascular diseases have become the second most common cause of death in Japan, and 40% of those deaths are attributed to ischemic heart disease...

Background: There are no primary prevention trials of aspirin with relevant geriatric outcomes in elderly people. ASPirin in Reducing Events in the Elderly (ASPREE) is a placebo-controlled trial of low-dose aspirin that will determine whether 5 years of daily 100-mg enteric-coated aspirin extends disability-free and dementia-free life in a healthy elderly population and whether these benefits outweigh the risks. Methods: Set in primary care, this randomized double-blind placebo-controlled trial has a composite primary endpoint of death, incident dementia or persistent physical disability...

The development of coronary revascularization has dramatically improved early cardiovascular outcomes in patients with acute coronary syndrome (ACS). However, patients who have experienced myocardial infarction (MI) are at high risk of recurrence of cardiovascular events compared with those who are healthy or have stable coronary artery disease. Acute coronary events induce further inflammatory responses and plaque vulnerability in either a coronary culprit or whole vessels. The majority of data have supported the importance of coronary risk management to prevent secondary events...

A high percentage of type 2 diabetes mellitus (T2D) patients are also affected by dyslipidemia and chronic periodontitis (CP), but no studies have determined the gene expression in patients that are simultaneously affected by all three diseases. We investigated the systemic expression of immune-related genes in T2D, dyslipidemia, and CP patients. One hundred and fifty patients were separated into five groups containing 30 individuals each: (G1) poorly controlled T2D with dyslipidemia and CP; (G2) well-controlled T2D with dyslipidemia and CP; (G3) normoglycemic individuals with dyslipidemia and CP; (G4) healthy individuals with CP; (G5) systemic and periodontally healthy individuals...

Glucocorticoids promote lipolysis in white adipose tissue (WAT) to adapt to energy demands under stress, while superfluous lipolysis causes metabolic disorders, including dyslipidemia and hepatic steatosis. Glucocorticoid-induced lipolysis requires the phosphorylation of cytosolic hormone sensitive lipase (HSL) and perilipin 1 (Plin1) in the lipid droplet by protein kinase A (PKA). We previously identified Pik3r1 (a.k.a. p85α) as a glucocorticoid receptor target gene. Here, we found that glucocorticoids increased HSL phosphorylation, but not Plin1 phosphorylation, in adipose tissue-specific Pik3r1-null (AKO) mice...

Single nucleotide polymorphisms (SNPs) within a β-adrenergic receptor (ADRB2) were shown to be related to lipid traits or hyperlipidemia in different ethnicities, but not in a Chinese population. We performed the present study to investigate the possible relationship between them in a Chinese hypertensive population. Seven hundred and eighty-three hypertensive subjects were enrolled in the hospital-based retrospective research. Using the TaqMan PCR method, three polymorphisms (C-47T, A46G, and C79G) of ADRB2 were detected...

Chronic kidney disease (CKD) results in significant dyslipidemia and profound changes in lipid and lipoprotein metabolism. The associated dyslipidemia, in turn, contributes to progression of CKD and its cardiovascular complications. To gain an in-depth insight into the disorders of lipid metabolism in advanced CKD, we applied UPLC-HDMS-based lipidomics to measure serum lipid metabolites in 180 patients with advanced CKD and 120 age-matched healthy controls. We found significant increases in the levels of total free fatty acids, glycerolipids and glycerophospholipids in patients with CKD...
