Just kidding !! I'm back from my adventure in the snow (Sweden and Alaska) Snowboarding was excellent.
Here is some interesting info i found: Differential effects of insulin on peripheral and visceral tissue protein synthesis. United States Department of Agriculture, Agricultural Research Service, Children's Nutrition Research Center, and Endocrinology and Metabolism Section, Department of Pediatrics, Baylor College of Medicine, Houston, Texas 77030 We recently demonstrated that, with amino acids and glucose maintained at fasting levels, the stimulation of protein synthesis in latissimus dorsi muscle with feeding can be reproduced by a physiological rise in insulin alone. In the current report, we determine whether the response of protein synthesis to insulin is. 1) present in muscles of different fiber types, 2) proportional in myofibrillar and sarcoplasmic proteins, 3) associated with increased translational efficiency and ribosome number, and 4) present in other peripheral tissues and in viscera. Hyperinsulinemic-euglycemic-amino acid clamps were performed with 0, 30, 100, or 1,000 ng · kg0.66 · min1 of insulin to reproduce insulin levels present in fasted, fed, refed, and supraphysiological conditions, respectively. Tissue protein synthesis was measured using a flooding dose of L-[4-3H]phenylalanine. Insulin increased protein synthesis in gastrocnemius muscle and, to a lesser degree, latissimus muscle. The degree of stimulation of protein synthesis by insulin was similar in myofibrillar and sarcoplasmic proteins. Insulin increased translational efficiency but had no effect on ribosome number in muscle. Insulin also stimulated protein synthesis in skin but not in liver, intestine, spleen, pancreas, or kidney. The results support the hypothesis that insulin mediates the feeding-induced stimulation of myofibrillar and sarcoplasmic protein synthesis in muscles of different fiber types by increasing the efficiency of translation. However, insulin does not appear to be involved in the feeding-induced stimulation of protein synthesis in visceral tissues. Thus different mechanisms regulate the growth of peripheral and visceral tissues in the neonate. I'm liking insulin more and more these days.. Peace all. there will be new info in my newsletter this month for those who get it..

Hmmph... you go snowboarding and you don't drop by and pick me up? Are you NUTS??!! LOL
Welcome back SnowBear... J the snowbunny (even though I live in an oven. LOL)

Glad you had fun D-F. We're headed to CO in late Feb. I love skiing! One day I need to try snowboarding. But it's hard to give up the skis when we only get one trip a year.

Why hell, I missed you also.
Sounds like quite a interesting adventure. Take Care, Shine.
