UNASSIGNED: This matched case-control study conducted on 36 healthy women aged 18-50 years old. An indirect calorimeter and impedance body analyzer were used to assess resting metabolic rate (RMR) and body composition, respectively. Dietary intake and physical activity were assessed using questionnaires. To determine the abundance of the abovementioned gut microbiota, quantitative polymerase chain reaction (qPCR) method was performed. Moreover, ELISA kits were used to assess leptin, ghrelin, and insulin hormones.
UNASSIGNED: The results highlighted higher load of Firmicutes (p = 0.02), F. prausnitzii (p < 0.001), and B. fragilis (p = 0.02) in the normometabolic individuals compared to the hypometabolic ones. Besides, the positive correlation between the abundance of Firmicutes (β = 7.76 × 10-1, p = 0.01), F. prausnitzii (β = 1.29 × 10-5, p = 0.01), and B. fragilis (β = 4.13 × 10-6, p = 0.04) with the RMR have been shown. Whereas the abundance of Bacteroidetes, A. muciniphila, Lactobacillus spp., Bifidobactrium spp., and E. coli showed no significant difference (p > 0.05) and no significant correlation with the RMR except Lactobacillus spp. (β = 1.73 × 10-4, p = 0.01).
UNASSIGNED: It seems that gut microbiota can be a potential target for refining host energy homeostasis and treating obesity and its consequences.
■这项匹配的病例对照研究对36名年龄在18-50岁的健康女性进行。间接量热计和阻抗体分析仪用于评估静息代谢率(RMR)和身体成分,分别。使用问卷评估饮食摄入量和身体活动。为了确定上述肠道微生物群的丰度,进行定量聚合酶链反应(qPCR)方法。此外,ELISA试剂盒用于评估瘦素,ghrelin,和胰岛素激素。
■结果突出显示了较高的Firmicutes负载(p=0.02),F.prausnitzii(p<0.001),与低代谢个体相比,正常代谢个体和脆弱芽孢杆菌(p=0.02)。此外,Firmicutes的丰度之间呈正相关(β=7.76×10-1,p=0.01),F.prausnitzii(β=1.29×10-5,p=0.01),已经显示了具有RMR的B.fragilis(β=4.13×10-6,p=0.04)。然而丰富的拟杆菌,A.粘液虫,乳杆菌属。,双歧杆菌属。,大肠杆菌除乳酸杆菌外,与RMR无显著差异(p>0.05),与RMR无显著相关性。(β=1.73×10-4,p=0.01)。
■似乎肠道微生物群可以成为改善宿主能量稳态和治疗肥胖及其后果的潜在目标。
