compared with HC subjects (SMD = −0.31; 95% CI (−0.70, 0.08); p = 0.117).
(SMD = −0.37, 95% CI (−0.60; −0.13); p = 0.002).
The cognitive impairment induced by zinc deficiency in rats aged
0∼2 months related to BDNF DNA methylation changes in the hippocampus.
缺鋅引起的認知功能障礙與海馬BDNF DNA甲基化改變有關
zinc-adequate group (ZA: zinc 30 mg/kg diet)
鋅充足組(ZA:鋅30 mg / kg飲食)
zinc-deprived group (ZD: zinc 1 mg/kg diet)
缺鋅組(ZD:鋅1 mg / kg飲食)
a pair-fed group (PF: zinc 30 mg/kg diet)
一對餵養組(PF:鋅30 mg / kg飲食)
brain-derived neurotrophic factor (BDNF)
腦源性神經營養因子(BDNF)
Interestingly, the DNA methylation of the BDNF exon IX was
significantly increased in the ZD group, compared with
the ZA and PF groups, whereas the expression of
the BDNF mRNA was decreased.
與ZA和PF組相比,ZD組中BDNF外顯子IX的DNA甲基化顯著增加,
而BDNF mRNA的表達降低。
The concomitant evolution between plasma Se decrease over a 9-year period
and cognitive decline suggested that optimal Se status is potentially
important to maintain neuropsychological functions in aging people.
血漿Se在9年期間減少和認知下降之間伴隨的改變表明最佳Se(硒)狀態對於
維持老年人的神經心理功能可能是重要的。
Studies show that decreased antioxidant system is related to cognitive decline.
研究表明,抗氧化系統的減少與認知能力下降有關。
Thus we aimed to measure selenium (Se) status in Alzheimer's disease (AD)
and mild cognitive impairment (MCI) elderly and compared them with
a control group (CG).
測量老年癡呆症(AD)和輕度認知障礙(MCI)老年人的硒(Se)狀態,
並將其與對照組(CG)進行比較。
It is observed that erythrocyte Se decreases as cognition function does.
觀察到紅細胞(紅血球)Se(硒)隨著認知功能的降低而降低。
Our findings suggest that the deficiency of Se may contribute to cognitive
decline among aging people.
我們的研究結果表明,硒的缺乏可能導致老年人認知能力下降。
