OBJECTIVE
Obesity causes an imbalance in fat mass distribution between visceral and subcutaneous adipose tissue (AT) depots. We tested the hypothesis that this relates to increased NEFA uptake between these depots in obese compared with healthy participants. Second, we hypothesised that a diet very
Obesity is associated with increased fatty acid uptake in the myocardium, and this may have deleterious effects on cardiac function. The aim of this study was to evaluate how weight loss influences myocardial metabolism and cardiac work in obese adults. Thirty-four obese (mean body mass index 33.7
BACKGROUND
Glucolipotoxicity is believed to induce pancreatic β-cell dysfunction in obesity. Previously, it has not been possible to study pancreatic metabolism and blood flow in humans.
OBJECTIVE
The objective of the study was to investigate whether pancreatic metabolism and blood flow are altered
OBJECTIVE
Obesity is characterized by increased levels of plasma free fatty acids (FFAs) that interfere with insulin signaling. The aim of our study was to assess the FFA profile in obese children and adolescents and to determine their relation with different degrees of insulin resistance.
METHODS
A
Polycystic ovary syndrome (PCOS) is mainly defined by hyperandrogenism but is also characterized by insulin resistance (IR). Studies showed that overexposure of nonadipose tissues to nonesterified fatty acids (NEFA) may explain both IR and hyperandrogenism. Recent studies indicate that treatment
Preclinical studies have shown that brain FFA handling can be involved in the control of whole-body homeostasis, but data in humans are scanty. We investigated whether there are differences in brain fatty acid uptake (BFAU) between morbidly obese and lean subjects, and the effect of Pentadecanoic acid (15:0) and heptadecanoic acid (17:0), the dairy-specific saturated fatty acids have been inversely, while inflammation and oxidative stress have been positively related to the risk of cardiovascular disease (CVD). Both fatty acid metabolism and inflammation and oxidative stress
Fatty acids (FAs) have been postulated to impact adiposity, but few epidemiological studies addressing this hypothesis have been conducted. This study investigated the association between serum phospholipid FAs (S-PLFAs) and indicators of obesity. BMI and waist-to-hip ratio (WHR) were collected from
Oral 14(R,S)-[(18)F]-fluoro-6-thia-heptadecanoic acid was used to determine whether an increase in cardiac dietary fatty acid (DFA) metabolism in impaired glucose tolerance (IGT) is different in men and women. Myocardial DFA partitioning after 6 h was higher in IGT versus control subjects (P =
OBJECTIVE
Brown adipose tissue (BAT) is involved in energy dissipation and cytokine production and is potentially beneficial for the human body. The aim of the paper is to review the literature on adiposity-related cancer and functional imaging of BAT.
METHODS
We performed a review on
BACKGROUND
Bariatric surgery leads to a rapid and sustained weight loss often accompanied with improvement in glucose homeostasis.
OBJECTIVE
The objective of this study was to investigate the effects of bariatric surgery on pancreatic lipid metabolism, blood flow, and glycemic control.
METHODS
This
OBJECTIVE
To test whether brain fatty acid uptake is enhanced in obese subjects with metabolic syndrome (MS) and whether weight reduction modifies it.
METHODS
We measured brain fatty acid uptake in a group of 23 patients with MS and 7 age-matched healthy control subjects during fasting conditions
OBJECTIVE
Weight loss has been shown to decrease liver fat content and whole-body insulin resistance. The current study was conducted to investigate the simultaneous effects of rapid weight reduction with a very-low-calorie diet on liver glucose and fatty acid metabolism and liver
OBJECTIVE
Brown adipose tissue (BAT) has transformed from an interfering tissue in oncological (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) to an independent imaging research field. This review takes the perspective from the imaging methodology on which human BAT research has
Impaired cardiac systolic and diastolic function has been observed in preclinical models and in subjects with type 2 diabetes. Using a recently validated positron emission tomography (PET) imaging method with 14(R,S)-[(¹⁸F]-fluoro-6-thia-heptadecanoic acid to quantify organ-specific dietary fatty
