Why pigs and people absorb more sugar from their diet than fish

Researchers at the University of Saskatchewan in Canada compared how pigs and fish absorb glucose (i.e. sugar) from the diet. They did this by measuring how well glucose moves across the intestinal wall. Their findings appear in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology.  Transport of dietary glucose from the gut to the blood is facilitated by glucose transporters that pick up glucose and move it […]

Porcine heart donors

Have you heard about the research being conducted to improve the use of pig hearts for human transplants?  A recent article from Discover Magazine reported on a study in which researchers were able to keep a baboon alive for 6 months with a transplanted pig heart. While pig hearts are similar to primate hearts, a major problem with xenotransplantation is that they are not only bigger to begin with, they […]

Porcine adaptation to heat stress

  A new study published in American Journal of Physiology – Regulatory, Integrative and Comparative Physiology explored the effects of modest heat stress (35°C, 95°F) on the physiology of pigs. The found that pigs exposed to heat stress ate less than those exposed to ambient temperatures. I understand. I eat less when it is hot outside too. Since skeletal muscle is such a large metabolically active tissue, things that alter muscle metabolism […]
