[Q]: Question: Is prooxidant-anti-oxidant balance associated with extent of coronary artery disease?
Answer: In conclusion, we found higher levels of oxidative stress in CAD+ patients compared to healthy subjects. The oxidation level was not related to measures of the extent of CAD such as number of stenosed vessels.
[A]: no


[Q]: Question: Does incidental parathyroidectomy during thyroid surgery cause transient symptomatic hypocalcemia?
Answer: Unintended parathyroidectomy, although not uncommon, is not associated with symptomatic postoperative hypocalcemia. Modified radical neck dissection may increase the risk of incidental parathyroidectomy. Most of the glands removed were intrathyroidal, so changes in surgical technique are unlikely to markedly reduce this risk.
[A]: no


[Q]: Question: Is except for alanine , muscle protein catabolism influenced by alterations in glucose metabolism during sepsis?
Answer: The findings of this study demonstrate a universal acceleration in the metabolic rates of both intermediary glucose metabolism and protein/amino acid catabolism during sepsis. Except for alanine, however, there appears to be no coupling between these two physiologic responses to sepsis.
[A]:
no
