Comparison between Holstein cow's milk and Japanese-Saanen goat's milk in fatty acid composition, lipid digestibility and protein profile.

The fatty acid composition, the lipid digestibility and protein profile of Japanese-Saanen goat's milk were characterized. Caprine milk contained substantial quantities of C(4:0) to C(10:0) fatty acids as compared with Holstein cow's milk. The lipids of the former showed significantly higher digestibility in vitro by porcine lipase than those of the latter (P<0.

Heat stress facilitates stretch-induced hypertrophy of cultured muscle cells.

Increased mechanical stress induced by stretch is an important growth stimulus in skeletal muscle. Heat shock proteins (HSPs) are an important family of endogenous, protective proteins. HSP90 and HSP70 families show elevated levels under beat stress.

Expression of heat shock protein 72 in rat quadriceps muscles following anterior cruciate ligament resection.

This study investigated the expression of heat shock protein 72 (HSP 72) in quadriceps femoris muscle following anterior cruciate ligament (ACL) resection and running training in rats. A group of 15 Wistar strain male rats (10 weeks old) were divided into three groups: sham-operated (S), ACL resection (A), and running training following ACL resection (R). In the A and R groups, the ACL of the right knee was resected using microsurgical techniques.

Profiles of connectin (titin) in atrophied soleus muscle induced by unloading of rats.

Responses of the properties of connectin molecules in the slow-twitch soleus (Sol) and fast-twitch extensor digitorum longus muscles of rats to 3 days of unloading with or without 3-day reloading were investigated. The wet weight (relative to body wt) of Sol, not of extensor digitorum longus, in the unloaded group was significantly less than in the age-matched control (P < 0.05).
