question:
Question: Does degenerative spondylolisthesis affect the outcome of unilateral laminotomy with bilateral decompression in patients with lumbar stenosis?
Answer: Our study thus indicates that preoperative degenerative spondylolisthesis does not worsen the outcome of patients with lumbar stenosis undergoing unilateral laminotomy with bilateral decompression. These results suggest that lumbar fusion is often unnecessary in patients with degenerative spondylolisthesis and lumbar stenosis if the posterior decompression technique is unilateral laminotomy with bilateral decompression.
answer:
no


question:
Question: Is human in vitro oocyte maturation associated with increased imprinting error rates at LIT1 , SNRPN , PEG3 and GTL2?
Answer: There is no significant increase in imprinting mutations at LIT1, SNRPN, PEG3 and GTL2 after IVM of cumulus-enclosed GV oocytes from small antral follicles in minimally stimulated cycles without hCG priming.
answer:
no


question:
Question: Does traditional thermal therapy with indirect moxibustion decrease renal arterial resistive index?
Answer: This study of the short-term effects of indirect moxibustion on renal hemodynamics in healthy persons showed that renal vascular resistance was reduced after the therapy.
answer:

yes
