Active clinical trials for "Obesity"

Purpose: To investigate the uptake of VLDL-TG in visceral fat in lean and overweight individuals

The investigators propose to conduct a cross-sectional study of 60 participants who are 18-30 years of age to undergo research PET/CT. The purpose of this study is to investigate the relationships between Brown Adipose Tissue (BAT), the adiponectin/leptin (A/L) ratio, and components of the metabolic syndrome in young adults.

To scan the genome for obesity in a multi-ethnic sample.

Patient records from Johns Hopkins Weight Management Center historical files

Researchers at Harvard Pilgrim Health Care Institute and Massachusetts General Hospital are conducting a study to learn more about how best to reach out to women (age 18-45) who are thinking about a pregnancy in the next couple of years and currently have a BMI greater than 30 kg/m2. Interested participants will be asked to complete a 15-minute survey. The survey will ask some more questions about their prior reproductive health history, opinions and experiences regarding lifestyle, weight and health. After completing the survey, researchers would like to arrange a time to complete a 20- to 30-minute semi-structured interview about their perceived health in the process of planning pregnancy.

This study provides a sound basis towards a better understanding of the biochemical mechanisms behind childhood obesity and its metabolic phenotypes, which will be of great importance towards the development of more personalized prevention and treatment in future.

The goals of this study are to 1) examine the relationships among inflammation, obesity, and asthma in people with HIV and 2) to test if special subtypes of cells or markers are present in the blood and lungs of people with HIV with asthma compared to those without asthma.

Although taste influences food choices and favours diseases like obesity, there is no consensus about the existence of correlations between bitterness and anthropometric variables. Also, an electronic-based method for data collection could provide a more appropriate way for the evaluation of taste perception and save time. The objective is to search for correlations between bitterness and anthropometric variables.

Impact of resected gastric volume on postoperative weight loss after laparoscopic sleeve gastrectomy for morbid obesity. Observational study with a mathematical method to approximate the calculation of the resected gastric volume after a sleeve gastrectomy and see the outcome on weight loss.

Adipose tissue is strongly correlated to obesity and diabetes which are two major problems in the worldwide. Adipose tissue is involved in modulating glucose and energy metabolism locally and systemically by secreting factors, called adipocytokines. Tetranectin (TN), a novel adipocytokine, is secreted by adipose tissues. TN may regulate the glucose/energy homeostasis to affect lipid accumulation.The role of TN in adipocytes with or without TN on regulation of adipose tissue growth and lipid metabolism is valuable to be studied. Materials and methods: Secreted proteins from human adipocyte culture medium were deciphered using 2-D polyacrylamide gel electrophoresis and determined by LC/MS with MALDI-TOF analysis of proteins. Adipose tissues were obtained from the breast of 15 women undergoing mastectomy. Serum samples from 200 normal healthy people and 54 breast cancer patients were assigned to either a lean or obese group according to the body mass index. The TN protein concentration was measured in the culture medium of stromal-vascular fraction (SVF)-derived adipocytes from healthy humans, breast cancer patients, pigs and also from 3T3-L1 cells. Associations between plasma TN and other biomarkers were assessed with Pearson's correlations and multivariable linear regression.
