Brown adipose tissue (BAT) is vital for proper thermogenesis during cold exposure in rodents, but until recently its presence in adult humans and its contribution to human metabolism were thought to be minimal or insignificant. Recent studies using PET with 18F-fluorodeoxyglucose (18FDG) have shown the presence of BAT in adult humans. However, whether BAT contributes to cold-induced nonshiverin...
Brown adipose tissue (BAT) activity is induced when humans are exposed to cold. Therefore, cold exposure prior to the 18F-FDG-PET/CT scan is used as a tool to quantify BAT. Several cooling protocols, including fixed and personalized ones are currently in use. The aim of the present study was to determine the effect of a new personalized cooling protocol where the shivering threshold was measure...

OBJECTIVES To determine whether early infectious diseases could explain the association between number of siblings and other markers of microbial exposure and the development of atopic dermatitis before the age of 18 months. DESIGN Cohort study. Information on atopic dermatitis, infectious diseases occurring before 6 months of age, number of siblings, early day care, pet keeping, farm residen...
Monique Ernst: Pet in Child Psychiatry: The Risks and Benefits of Studying Normal Healthy Children. Prog. Neuro-Psychopharmacol. & Biol. Psychiat. 1999,23, pp. 56~~70. Published by Eloevler Science Inc. 1. Inclusion of children, particularly healthy control children, is a continuing debate. 2. Why involve children in PET research? The assumption is that the knowledge gained from such studies is...
staging of neoplasms are crucial in determination of the appropriate therapy and assessment of the prognosis. Recently, positron emission tomography (PET) with 2-deoxy-2 [F] fluoro-d-glucose (FDG) in combination with computed tomography (PET-CT) has become an important imaging modality for the staging of various tumors as well as and monitoring of the therapy and follow up in some instances (1,...
This prospective pilot study provides a dynamic whole body PET/MR image database, clinical safety, biodistribution profile and dosimetry of 68Ga-DOTATOC in healthy subjects, to establish a baseline and standard reference for its use in diagnosis and treatment response evaluation among patients with somatostatin receptor expressing neoplastic diseases. Dynamic whole body PET/MR imaging was perfo...
Human brown adipose tissue (BAT) can be activated to increase glucose uptake and energy expenditure, making it a potential target for treating obesity and metabolic disease. Data on the functional and anatomic characteristics of BAT are limited, however. In 20 healthy young men [12 lean, mean body mass index (BMI) 23.2 ± 1.9 kg/m2; 8 obese, BMI 34.8 ± 3.3 kg/m2] after 5 h of tolerable cold expo...
