1. We assessed the variation in subcutaneous abdominal adipose tissue blood flow within and between subjects and investigated whether it is correlated with body mass index. 2. We measured body mass index and subcutaneous abdominal adipose tissue blood flow in 38 fasting subjects on the same day and on different days and, in a subgroup of 16 subjects, after a mixed meal. 3. In 190 measurements i...

White adipose tissues are composed mainly of white fat cells (adipocytes), which play a key role in energy storage and metabolism. White adipocytes are terminally differentiated postmitotic cells and arise from their progenitor cells (preadipocytes) or mesenchymal stem cells residing in white adipose tissues. Thus, white adipocyte number is most likely controlled by the rate of preadipocyte pro...

Recent studies indicate that the functional renin-angiotensin system (RAS) exists in the adipose tissue. The adipose tissue RAS is proposed in the pathophysiology of metabolic disorders. In the present study, we examined therapeutic effects of irbesartan, an angiotensin II (Ang II) type 1 receptor (AT1R)-specific blocker, in genetically obese diabetic KKAy mice, a model of human metabolic disor...

The effect of prolonged diabetes on epinephrine-induced adenosine 3',5'-monophosphate (cAMP) response in the liver was examined in diabetes-prone BB/W rats. Basal and 1,iM epinephrineinduced cAMP release from isolated perfused liver was similar in non-diabetic and diabetic BB/W rats with preserved adipose tissue. In adipose tissue-absent diabetic rats losing intraand retro-peritoneal adipose ti...

Adipose tissue distribution is different between women and men. Therefore, we have investigated the expression of steroid receptors in human adipose tissue and report that receptors for glucocorticoid androgen and estrogen are present in human adipose tissue. Furthermore, we discovered regional differences in expression pattern, indicating that steroid hormones might affect the different adipos...

OBJECTIVE To investigate whether gastric bypass induces a higher activity of brown adipose tissue and greater levels of the brown adipose tissue-specific protein uncoupling protein-1 (UCP-1) in rats. METHODS Gastric bypass rats and sham-operated controls (each n = 8) underwent whole body (1)H-MR spectroscopy for analysis of body composition and (18)F-fluorodeoxyglucose positron emission tomog...

BACKGROUND Successful long-term preservation of adipose tissues may have an important impact on future clinical application of autologous fat transplantation. Our group has recently developed an optimal cryopreservation method for possible long-term preservation of adipose aspirates. OBJECTIVE The purpose of this study was to evaluate the fate of previously cryopreserved adipose aspirates aft...

Distribution and concentration of beta-adrenergic receptor (betaAR) subtype transcripts (beta1AR, beta2AR, and beta3AR) were investigated in porcine and rat tissues. Reverse transcription (RT) coupled with PCR indicated the presence of beta1AR and beta2AR transcripts in porcine left ventricle, lung, longissimus muscle, and subcutaneous adipose tissue. The RT-PCR indicated that beta3AR transcrip...

OBJECTIVE Adipose tissue shows a high degree of plasticity, and adipocyte hyperplasia is an important mechanism for adipose tissue expansion. Different adipose depots respond differently to an increased demand for lipid storage. Orchestrating cellular expansion in vivo requires extracellular matrix (ECM) remodeling and a high degree of interaction between cells and ECM. METHODS We studied dec...

This thesis describes a method for automatically segmenting abdominal adipose tissue from 3-dimensional magnetic resonance images. The segmentation distinguishes between three types of adipose tissue; visceral adipose tissue, deep subcutaneous adipose tissue, and superficial subcutaneous adipose tissue. Prior to the segmentation, the image data is preprocessesed to remove withinclass image inte...
