Endometrioma surgery-a systematic review and meta-analysis of the effect on antral follicle count and anti-Müllerian hormone

Conclusion: Endometriotic cystectomies are associated with a significant reduction in the serum anti-Müllerian hormone levels but not in the antral follicle counts, with the detrimental effects on the anti-Müllerian hormone levels consistently detectable at the early-, intermediate-, and late-postoperative time points. In women with endometrioma, the anti-Müllerian hormone level may provide a more accurate assessment of the risk for iatrogenic depletion of the ovarian reserve.

Chinese herbs for memory disorders: a review and systematic analysis of classical herbal literature

Conclusion: Of the 110 different natural products identified, those most frequently cited for forgetfulness were yuan zhi (Polygala tenuifolia), fu shen (Poria cocos), and chang pu (Acorus spp.), all of which have been cited repeatedly over the past 1800 years and appear among the 31 herbs indexed in a modern pharmacopoeia. By providing a complete, hierarchically organized list of herbs for a specific disorder, this approach can assist researchers in selecting herbs for research.

Chinese herbs for dementia diseases

Conclusion: We encountered Acoris gramineus rhizome (AGR), Panax ginseng, Polygala tenuifolia and Poria cocos as the four most frequently used herbs as single/herbal mixtures that were associated with positive cognitive enhancing outcomes. This review focuses on the evidence of their medicinal effects attributed to those constituents present in relatively high concentration.
