[EX Q]: Question: Is muscle dysfunction during exercise of a single skeletal muscle in rats with congestive heart failure associated with reduced muscle blood supply?
Answer: The cause of contractile dysfunction in a single exercising skeletal muscle in rats with CHF cannot be explained simply by reduced blood supply. In addition, absence of changes in high-energy phosphates and metabolites indicate that the oxidative metabolism of SOL is intact in rats with CHF.

[EX Q]: Question: Do identification of methicillin-resistant Staphylococcus aureus ( MRSA ) strains isolated from burn patients by multiplex PCR?
Answer: This study presented a high MRSA rate in the region under investigation. The 16S rRNA-mecA-nuc multiplex PCR is a good tool for the rapid characterization of MRSA strains. This paper emphasizes the need for preventive measures and choosing effective antimicrobials against MRSA and MRCoNS infections in the burn units.
