Guanidinoacetate Is More Effective than Creatine at Enhancing Tissue Creatine Stores while Consequently Limiting Methionine Availability in Yucatan Miniature Pigs
Creatine (Cr) is an important high-energy phosphate buffer in tissues with a high energy demand such as muscle and brain and is consequently a highly consumed nutritional supplement. Creatine is synthesized via the S-adenosylmethionine (SAM) dependent methylation of guanidinoacetate (GAA) which is not regulated by a feedback mechanism. The first objective of this study was to determine the effe...
متن کاملConcise, intensive or longitudinal medical education courses, which is more effective in perceived self-efficacy and development of faculty members?
Background: Teachers’ self-efficacy and development may be conceptualized as their beliefs in their own ability to plan, organize and carry out activities that are required to attain educational goals. In this study, we examined the effect of different medical education training courses (six-day, one- month short- term and six-month long- term courses) on perceived self-effica...
متن کاملDetermination of creatine, creatinine, arginine, guanidinoacetic acid, guanidine, and methylguanidine in biological fluids.
The non-specific analytical methods for the guanidinium compounds in biological fluids have been unsatisfactory for many years. The methods presented in this paper have a greatly improved specificity and are not too complex for use in the clinical laboratory. A modified Sakaguchi color reaction for substituted guanidines is used in each procedure. Guanidinoacetic acid is measured by developing ...
متن کاملCreatine Metabolism and Safety Profiles after Six-Week Oral Guanidinoacetic Acid Administration in Healthy Humans
OBJECTIVES Guanidinoacetic acid (GAA) is a natural precursor of creatine, yet the potential use of GAA as a nutritional additive for restoring creatine availability in humans has been limited by unclear efficacy and safety after exogenous GAA administration. The present study evaluated the effects of orally administered GAA on serum and urinary GAA, creatine and creatinine concentration, and on...
متن کاملIs Long Term Creatine and Glutamine Supplementation Effective in Enhancing Physical Performance of Military Police Officers?
The objective of this study was to analyze the effect of supplementation with creatine and glutamine on physical fitness of military police officers. Therefore, an experimental double blind study was developed, with the final sample composed by 32 men randomly distributed into three groups: a group supplemented with creatine (n=10), glutamine (n=10) and a placebo group (n=12) and evaluated in t...
