...rates of synthesis of collagen and total
muscle protein after incubation with a constant tension or
intermittent mechanical stretching were compared with the rates in
vivo. Muscles incubated under a constant tension synthesized protein
at 22% of the rate observed in vivo; intermittent mechanical
stretching resulted in an increase of 73% in the rate of protein
synthesis, to 38% of that found in vivo. Collagen synthesis was
affected in the same way as total protein synthesis by both types of
incubation, therefore the relative rates of collagen and total

...nuclei) typically have rather complex internal structure. Most of this structure is generated from the cell's fluid matrix, but there are important exceptions. These are the mitochondria and the chloroplasts (as well as different-colored plastids). Mitochondria perform energy metabolism, combining electrons from food with oxygen (and hydrogen ions) to make water. Chloroplasts do photosynthesis. These organelles contain their own genes and their own DNA-RNA- protein synthesis systems. Why that should be necessary is not clear, given the other internal structures that do not need self-contained genetic systems, and also given the fact that many of the genes for proteins used in the mitochondria and chloroplasts reside in the nucleus. # PRZEMIANA POKOLE U ROSLIN** Alternation of generations: Many algae and "lower" plants, like mosses and ferns, have an alternation of generations between an asexual diploid...

...results in inhibition of protein
synthesis in human myoblasts, inhibition of collagen synthesis in rat
osteoblasts, and inhibition of human adipose tissue lipoprotein lipase.
TNF-alpha also may modulate cachexia by stimulating an increase in serum leptin,
a hormone believed to regulate body weight by decreasing appetite. Additionally,
both TNF-alpha and IL-1 act to reduce the availability of insulin-like growth
factor (IGF), which stimulates protein synthesis by increasing IGF binding
protein. In animal models of cachexia, administration of substances that either
decrease TNF-alpha levels (such as pentoxifylline, TNF-alpha antibody, and
soluble TNF-alpha receptor-containing copolymer) or inhibit the oxidative stress
produced by TNF-alpha, partially prevent anorexia and loss of body weight and
skeletal muscle protein."...

...has been found to be either no better, or in fact worse in terms of
performance of endurance exercise (3). As well, there is the issue of gastric
upset with high amounts of fructose that limits how much can be given in the
first place.
As a final comment, there is the issue of post-workout carbohydrate and
recovery. At this point, it should be no surprise to readers that the post-
workout consumption of carbs and protein improves recovery, performance and protein synthesis (32,33). Studies examining different types of carbohydrate
intake post workout have invariably found that glucose and glucose polymers
refill muscle glycogen ideally, while fructose preferentially refills liver
glycogen. In that refilling liver glycogen can be important from the standpoint
of overall recovery and growth (the details are outside of the scope of this
article), consuming a small amount of fructose (10% of the...

...For example, Watson discovered exactly how the base
pairs went together, which is structural. He made that discovery."
Their work led in 1953 to the proposal of the double-helical structure for DNA
and the replication scheme. Crick and Watson subsequently suggested a general
theory for the structure of small viruses. Later, in research with Sydney
Brenner, professor of genetic medicine at the University of Cambridge, Crick
developed ideas about protein synthesis ("the adaptor hypothesis") and the
genetic code.
By 1966, sensing that the foundation for molecular biology was adequately set,
Crick turned his attention to embryology. Then, in 1976, he joined the Salk
Institute for a sabbatical year from the Medical Research Council. The
following year, after 30 years and 87 scientific papers, he decided to make a
permanent switch to the Salk, where he pursued his interests in...
