The complement effect on Th17 cells is dependent on C5a-receptor expression and physiologically relevant levels of C5a [ 54].
Like the previous reports, and in contrast to the entire hypothalamus, a sex chromosome complement effect showed that XX mice had more GH than XY in the arcuate.
Science
Myocarditis scores showed a significant effect of sex chromosome complement, in which XX mice developed significantly more myocarditis than XY mice, irrespective of their gonadal sex (two-way ANOVA sex chromosome complement effect P < 0.009).
Science
Because the sex chromosome complement effect was in the opposite direction from our past reports in wild type and another sex chromosome mutant mouse model, we quantified GH protein in the arcuate nucleus.
Science
This result is surprising, as women are more vulnerable to mood disorders, and suggests that other factors (gonadal sex or circulating testosterone) in normal males may compensate for the sex chromosome complement effect on gene expression.
Science
It is worth mentioning that David [ 7] collected 32 papers in this field from 1957; 20 of the papers confirmed the positive relation between public and private investment, 8 agreed that there was a complement effect between them, and 4 did not find a significant relationship.

Up-regulation of this and other inflammatory mediators (e.g. IL-8 and receptor, IL-1, TNF-9) is consistent with a pro-inflammatory role for PAR2 activation, in contrast to the anti-inflammatory complement effects above.
Science
There were no significant sex or sex chromosome complement effects on errors in any section of the beam (data not shown).
Science
Blockade of C5, although potentially useful in minimizing complement effects during rejection, also prevents activation of the terminal complement cascade, theoretically decreasing MAC-mediated pathogen clearance induced by all pathways of complement (1).
Notably, the sex difference in learned helplessness in rats was not reversed after removal of adult hormones by gonadectomy [ 62], suggesting either developmental hormonal or sex chromosome complement effects.
Science
However, the anti-complement effect needs only be local (i.e. in the immediate proximity of the mouth parts and midgut epithelium), and this drastically reduces the amount of complement to be neutralized.

Expert writing Tips
Best practice
When using "complement effect", clearly specify what elements are complementing each other to avoid ambiguity.
Common error
Ensure you're not implying the effect is a substitute, but rather an enhancement. "Complement effect" suggests an additive or synergistic relationship, not a replacement.
