Adult stem cells from liposuction used to create blood vessels in the lab

Posted on Updated on

Researchers used stem cells from fat to grow new small-diameter blood vessels in the laboratory. Lab-grown small-diameter blood vessels could help patients undergoing procedures such as heart bypass surgery. Adult stem cells derived from fat are turned into smooth muscle cells in the laboratory, and then “seeded” onto a very thin collagen membrane. As the stem cells multiplied, the researchers rolled them into tubes matching the diameter of small blood vessels. In three to four weeks, they grew into usable blood vessels.

Night shift work linked to an increased risk of obesity

Posted on

In the analysis, night shift workers had a higher frequency of developing abdominal obesity than other obesity types. Permanent night workers demonstrated a higher risk than rotating shift workers. “Globally, nearly 0.7 billion workers are engaged in a shift work pattern. Our study revealed that much of the obesity and overweight among shift workers is attributable to such a job nature,” doctor said. “Obesity has been evident to be positively associated with several adverse health outcomes, such as breast cancer, cardiovascular diseases”.

Long-term stress linked to higher levels of obesity, hair samples show

Posted on

Chronic stress has long been hypothesized to be implicated in obesity — people tend to report overeating and ‘comfort eating’ foods high in fat, sugar, and calories in times of stress, and the stress hormone cortisol plays an important role in metabolism and determining where fat is stored.Previous studies looking at the link between cortisol and obesity relied mainly on measurements of the hormone in the blood, saliva or urine which may vary according to the time of day and other situational factors. These studies failed to capture long-term cortisol levels.

Junk Food Makes Kids Fatter, But Happier, Study Suggests

Posted on

Children who ate fast food and drank soft drinks were more likely to be overweight, but they were also less likely to be unhappy. The analysis also highlighted a number of factors influencing children’s body weight, eating patterns and happiness. For example, mothers’ consumption of fast food and soft drinks predicted her child’s eating habits. Those children who ate fast food were more likely to also consume soft drinks. Children from lower income households were more likely to have unhealthy dietary habits and be overweight or obese.

Obesity: Is junk food really to blame?

Posted on

Soda, candy, and fast food are often painted as the prime culprits in the national discussion of obesity in the United States. While a diet of chocolate bars and cheese burgers washed down with a Coke is inadvisable from a nutritional standpoint, these foods are not likely to be a leading cause of obesity in the United States according to a new study.

Brain ‘switch’ tells body to burn fat after a meal

Posted on

Scientists have found a mechanism by which the brain coordinates feeding with energy expenditure, solving a puzzle that has previously eluded researchers and offering a potential novel target for the treatment of obesity. Feeding controls the ‘browning’ of fat, that is, the conversion of white fat, which stores energy, into brown fat, which expends it. Fat in the human body is stored in specialized cells called adipocytes, which can change from white to brown states and back again.
