Dry fermented sausages with different fat contents were produced (10%, 20% and 30%). The effect of fat content and ripening time on sensory characteristics, lipolysis, lipid oxidation and volatile compounds generation was studied. Also, the key aroma components were identified using gas chromatography (GC) and olfactometry. High fat sausages showed the highest lipolysis and lipid oxidation, det...

OBJECTIVE This aim of this study was to evaluate the role of different wavelengths (920 nm, 980 nm, 1064 nm, 1320 nm, and 1440 nm) in laser lipolysis. BACKGROUND Laser lipolysis is fast becoming a recognized technique for fat reduction. It has been demonstrated that (i) fat liquefaction is induced through a temperature elevation of the adipocyte cells, and (ii) fat volume reduction depends on...

Animal/cell investigations indicate that there is a decreased adipose tissue mass resulting from skeletal muscle (SkM) IL-15 secretion (e.g., SkM-blood-adipose tissue axis). IL-15 could regulate fat mass accumulation in obesity via lipolysis, although this has not been investigated in humans. Therefore, the purpose was to examine whether SkM and/or subcutaneous adipose tissue (SCAT) IL-15 conce...

The CB1 receptor antagonist, rimonabant, affects the endocannabinoid system and causes a sustained reduction in body weight (BW) despite the transient nature of the reduction in food intake. Therefore, in a multiple-dose study, female candy-fed Wistar rats were treated with rimonabant (10 mg/kg) and matched with pair-fed rats to distinguish between hypophagic action and hypothesized effects on ...

Lactoferrin (LF) is a multifunctional glycoprotein present in milk. A clinical study showed that enteric-coated bovine LF tablets decrease visceral fat accumulation. Furthermore, animal studies revealed that ingested LF is partially delivered to mesenteric fat, and in vitro studies showed that LF promotes lipolysis in mature adipocytes. The aim of the present study was to determine the mechanis...

The sympathetic nervous system (SNS) drive on white adipose tissue (WAT) was varied to test its effects on fat cell number (FCN) under conditions in which lipolysis would be minimized and therefore partially separable from SNS trophic effects. The inguinal subcutaneous WAT (IWAT) pad of Siberian hamsters was chosen because 1) it is innervated by the SNS, 2) short day (SD) exposure increases its...

In white adipose tissue, lipolysis can occur by hormone-sensitive lipase (HSL)-dependent or HSL-independent pathways. To study HSL-independent lipolysis, we placed HSL-deficient mice in conditions of increased fatty acid flux: beta-adrenergic stimulation, fasting, and dietary fat loading. Intraperitoneal administration of the beta(3)-adrenergic agonist CL-316243 caused a greater increase in non...

Beta3-Adrenoceptors are involved in the control of catecholamine-induced lipolysis in rodent adipose tissues. The expression and function of human beta3-adrenoceptors were investigated in subcutaneous white adipocytes of young healthy women. In these cells, beta3-adrenoceptor mRNAs represent 20% of total amount of beta-adrenoceptor transcripts and less than half of beta1-adrenoceptor transcript...

Using a new approach based on simultaneous measurements of net changes in glycerol and free fatty acids, the rates of lipolysis and of fatty acid esterification were estimated in rat epididymal fat pads under various conditions in vitro. Glycerol release, taken as a measure of the rate of lipolysis, was stimulated by epinephrine, norepinephrine, glucagon, adrenocorticotropic hormone (ACTH), thy...

Objective: This study aims to investigate the effect of astragaloside IV on adipose lipolysis and hepatic gluconeogenesis. Methods: High-fat diet (HFD) feeding induced adipose dysfunction with enhanced endogenous glucose production in mice. The effects of Astragaloside IV on lipolysis and hepatic glucose production were investigated. Results: HFD feeding induced cAMP accumulation through reduci...
