Researchers explore why fetuses that experienced intrauterine growth restriction have smaller muscles

We have talked several times about the long-lasting issues related to growth restriction of a fetus during pregnancy: Intrauterine growth restriction increases risk of cardiovascular disease as adults Intrauterine growth restriction increases risk of insulin resistance as adults It can also result in offspring that have smaller muscles. New research published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology suggests this may be due to adaptations to […]

Researchers in Washington scheduled to talk about physiology

The Greater Washington DC Area Physiological Society will be hosting their 6th annual meeting on Monday at The George Washington University. This year’s distinguished speaker will be Dr. Nehal N. Mehta, a Lasker Clinical Research Scholar at the National Institutes of Health. Dr. Mehta’s research examines how inflammation leads to insulin resistance and the development of metabolic and cardiovascular disease. Other invited speakers include: Dr. Brian Glancy, an Earl Stadtman Investigator […]

Growth restriction in utero increases risk for developing insulin resistance

  A new study published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology, explored how restricted growth of a fetus during pregnancy can lead to insulin resistance later in life. They studied this risk factor in guinea pigs as larger litter sizes are known to restrict the growth of developing fetuses. Findings from the study showed that neonatal guinea pigs grow rapidly after birth to compensate for […]

Caffeine redemption

Sometimes caffeine gets bad rap. But, not all caffeine drinks are created equal and certainly there are health issues related to over-consumption. But, as an avid coffee drinker, I’d like to think there are some benefits to my favorite morning treat. A recent article published in American Journal of Physiology – Endocrinology and Metabolism highlighted some of the health benefits of caffeine. Thank you AJP! Obesity is a complicated condition that can […]

How Ossabaw Island swine are helping us understand obesity and diabetes

         Ossabaw Island off the coast of Georgia (United States) is home to feral swine brought over by early Spanish explorers. In relative isolation on the island, with the exception of the introduction of a Hampshire pig, the Ossabaw pigs have become genetically distinct from those living on the mainland. Ossabaw pigs are prone to obesity and are the only miniature pigs known to develop type 2 […]
