Urinary Glyphosate Concentrations and Serum Sex Hormones in a Nationally Representative U.S. Sample: NHANES 2017-2018.

Glyphosate and glyphosate-based herbicides (GBHS) are the most widely used herbicides worldwide, yet their potential endocrine-disrupting effects in humans remain inadequately studied. We analyzed data from 1532 participants aged ≥6 years in the 2017-2018 National Health and Nutrition Examination Survey (NHANES). Serum sex hormones assessed included follicle-stimulating hormone (FSH), luteinizing hormone (LH), anti-Müllerian hormone (AMH), androstenedione, estrone, estradiol, estrone sulfate, 17α-hydroxyprogesterone, progesterone, and sex hormone-binding globulin (SHBG).

Glyphosate Exposure, Oxidative Stress, Mitochondrial Dysfunction, and Mortality Risk in US Adults: Insights from the National Health and Nutrition Examination Survey.

Glyphosate and glyphosate-based herbicides (GBHs) are widely used across the globe. Experimental research indicates that these herbicides may elevate oxidative stress and impair mitochondrial function. However, the relationship between glyphosate exposure, oxidative stress, and mitochondrial function remains poorly characterized in epidemiological studies.

Reduced encoding diffusion spectrum imaging implemented with a bi-Gaussian model.

Diffusion spectrum imaging (DSI) can map complex fiber microstructures in tissues by characterizing their 3-D water diffusion spectra. However, a long acquisition time is required for adequate q-space sampling to completely reconstruct the 3-D diffusion probability density function. Furthermore, to achieve a high q-value encoding for sufficient spatial resolution, the diffusion gradient duration and the diffusion time are usually lengthened on a clinical scanner, resulting in a long echo time and low signal-to-noise ratio of diffusion-weighted images.
