does boosting 'good' cholesterol really improve your health?




a new review addresses the mysteries behind "good" hdl cholesterol and why boosting its levels does not necessarily provide protection from cardiovascular risk for patients. it appears that augmenting the function of hdl cholesterol, rather than its concentration, is key. the review details the mann...



fat tissue may impede radiotherapy for breast cancer patients




according to research published online in the faseb journal, repeated irradiation of breast fat (also known as adipose tissue) produces an inflammatory response that ultimately reduces the efficiency of radiotherapy in breast cancer patients. this research was based on a recent discovery that there ...

study shows adipose stem cells may be the cell of choice for therapeutic applica




an international team of researchers, funded by morris animal foundation, has shown that adipose (fat) stem cells might be the preferred stem cell type for use in canine therapeutic applications, including orthopedic diseases and injury.researchers at the university of guelph, university of western ...



why do some obese people have 'healthier' fat tissue than others?




ann arbor--one little understood paradox in the study of obesity is that overweight people who break down fat at a high rate are less healthy than peers who store their fat more effectively. that's because when fat breaks down, many of the fatty acids released from the adipose tissue (body fat) can ...
