Micronutrient Deficiencies and Conception in Idiopathic Infertility: A Prospective Single-Centre Cohort Study

In a prospective single-centre cohort study of 27 women with idiopathic infertility in Dubai, universal micronutrient deficiencies were identified and corrected through individualised supplementation, resulting in a 74.1% clinical pregnancy rate within 12 months and suggesting that routine nutritional screening warrants further investigation in infertility workups.

Altitudinal gradient drives significant changes in soil physico-chemical properties and microbial community after ecological restoration on Qinghai-Tibetan plateau

This study demonstrates that on the Qinghai-Tibetan Plateau, ecological restoration of artificial slopes leads to significant altitudinal and spatial variations in soil physico-chemical properties and microbial community structure, driven primarily by altitude, soil depth, pH, and nutrient availability, which in turn influence the abundance of key functional genes.
