• Insulin resistance ( IR ) is a pathological condition in which cells fail to respond normally to the hormone insulin . (wikipedia.org)

  • Central leptin increases peripheral insulin sensitivity through unknown mechanisms. (auburn.edu)
  • Central insulin signaling may also contribute to peripheral insulin sensitivity. (auburn.edu)
  • To clarify the relationships among central leptin, central insulin, peripheral insulin sensitivity, and adiponectin, we examined the effects of intracerebroventricular leptin and insulin on peripheral insulin sensitivity and adiponectin concentrations in streptozotocin (STZ)-induced diabetic rats. (auburn.edu)
  • After one week of central administration, in vivo insulin sensitivity was measured by injecting IV insulin (0.025 U/kg body weight) and measuring blood glucose concentration 15 minutes after the injection. (auburn.edu)
  • Rats treated with central leptin had increased peripheral insulin sensitivity. (auburn.edu)
  • Central insulin administration did not affect insulin sensitivity or normalize blood glucose concentrations. (auburn.edu)
  • This appears to suggest that an intact sympathetic nervous system is not required for central leptin to enhance peripheral insulin sensitivity. (auburn.edu)
  • Therefore, further study is needed to determine the role of the sympathetic nervous system in mediating central leptin's effect on peripheral insulin sensitivity in diabetic rat. (auburn.edu)

  • It has an onset of action 15-60 min after injection, a peak effect 2-4 h after injection, and a duration of action of ranging from 5 to 8 h. 14 For best results, the slow onset of regular insulin requires it to be administered 30-60 min before meals, which is certainly not a convenient way for busy or hungry people with diabetes to prepare for meals. (diabetesjournals.org)

  • Under normal conditions of insulin reactivity, this insulin response triggers glucose being taken into body cells, to be used for energy , and inhibits the body from using fat for energy, thereby causing the concentration of glucose in the blood to decrease as a result, staying within the normal range even when a large amount of carbohydrates is consumed. (wikipedia.org)
  • Others, including C. geographus , secrete insulin, alongside other compounds, into the water, causing the blood sugar in nearby fish to plummet and sending the fish into hypoglycemic sedation. (utah.edu)
