PROBLEM: Question: Is serum Reg-Ialpha suitable marker of metabolic syndrome?
Answer: Our study, for the first time, indicates that serum Reg-1alpha is not useful for the diagnosis of metabolic syndrome (Tab. 3, Ref. 7).

SOLUTION: no

PROBLEM: Question: Are ethnic variations in uterine leiomyoma biology caused by differences in myometrial estrogen receptor alpha levels?
Answer: Neither on a transcriptional nor on a protein level were there statistically relevant differences in steroid hormone receptor levels. A causative role for these receptors in the ethnic variation of leiomyoma biology seems unlikely.

SOLUTION: no

PROBLEM: Question: Does drought degree constrain the beneficial effects of a fungal endophyte on Atractylodes lancea?
Answer: Plant traits plasticity was conferred by dual effects of drought stress and FEs, and these factors are interactive. Although FEs can help plants cope with drought stress, the beneficial effects are strictly constrained by drought degree.

SOLUTION:
yes
