Post-Mortem Chemical Changes in Muscle - Meat Aging

Since the earliest days of muscle science, physiologists have been attracted to the phenomenon of rigor mortis. Because considerable quantities of lactic acid accumulate in post-mortem muscle, the characteristic stiffness of rigor was originally attributed to the denaturation and reduced solubility of proteins at the lowered pH. However, some 50 years ago (Lundsgaard, 1930) this comfortable vie...

Muscle Changes in Aging

UNLABELLED Muscle physiology in the aging athlete is complex. Sarcopenia, the age-related decrease in lean muscle mass, can alter activity level and affect quality of life. This review addresses the microscopic and macroscopic changes in muscle with age, recognizes contributing factors including nutrition and changes in hormone levels, and identifies potential pharmacologic agents in clinical t...

Some Chemical Changes Exhibited in Sterile and in Contaminated Haddock Muscle Stored at Different Temperatures.

The bio-chemical changes which occur in fish tissues are due to two factors, autolysis and bacterial action. As early as 1903, Muller reported that changes due to autolysis took place when sterile fish tissues were incubated. More recently attention has been focussed on the relative importance of these two causes of bio-chemical change. Reed, Rice and Sinclair (1929) presented evidence that aut...

Chemical Changes in Amniotic Fluid

The scope of my talk as represented by its title encompasses a very large field which time does not allow me to cover in its entirety. Therefore, I will limit my remarks to one very specific area where chemical changes in amniotic fluid could be used to predict fetal maturity. An ever present dilemma in modern obstetrical management is the proper timing of delivery of the fetus in situations wh...
