研究问题

However, the mechanisms underlying these sex differences remain poorly understood.

方法

However, the mechanisms underlying these sex differences remain poorly understood.

核心结论

The results showed that both sexes fed the HFHC diet developed obesity and dyslipidemia, with males exhibiting a more severe phenotype.;Furthermore, males exhibited more severe mitochondrial dysfunction and higher oxidative stress levels compared to females, manifesting as reduced muscle strength and upregulated atrophy-related gene expression.

局限

(原文未给出可直接抽取的对应表述)

对本项目的价值

临床前机制证据,需评估物种外推与剂量可行性:微生物组是可修饰性最强的干预层,适合做组合与个体化。 | 价值分 1.2/5(★☆☆☆☆)

B 级证据分级:B 级(同行评议临床前研究,主要为动物模型)

本文核心结论来自动物模型或体外细胞学,属临床前证据,不能外推至人体。「延长健康寿命」「改善功能」等表述在小鼠中的意义,与人类临床结局之间仍有距离。
