This study developed and validated a comprehensive method using mass spectrometry to profile sex (pro)hormones in plasma, with results showing reliable calibration and detection of 31 analytes in samples from pre- and postmenopausal women and men, while addressing potential over- or underestimations in analyte concentrations.

This study found that among ten Curcuma aeruginosa accessions, the MD accession showed the highest anticancer activity against MCF-7 cells, suggesting its potential for pharmaceutical development.

In this study, the Trivedi Effect®-Consciousness Energy Healing Treatment was reported to significantly increase the solubility and isotopic abundance ratios of flutamide, potentially improving its stability and efficacy.

This study suggests that 9-Octadecenoic acid (Z)-, 2,3-dihydroxypropyl ester from African Yam bean seeds may inhibit the human 5α-reductase II enzyme, potentially helping manage BPH, although further studies are needed.

This study found that the chemical composition and biological activity of Platycladus orientalis fruit extracts varied with the extraction method, revealing potent antioxidant and enzyme inhibitory properties, particularly in the n-hexane extract, which suggests potential applications for managing dysregulated enzyme conditions.

This study reported that Neelibhringadi Kera Tailam, a traditional Ayurvedic herbal oil, contains bioactive compounds that may support hair health by stimulating growth, providing antimicrobial, antioxidant, and anti-inflammatory effects, and preventing hair loss, as evidenced by its physicochemical, phytochemical, and GC-MS analyses.

This study concluded that rosemary essential oil rich in terpenes was successfully extracted using vacuum-assisted hydrodistillation, and Solid Phase Micro Extraction was superior for identifying volatile compounds compared to direct injection.

This study identified significant metabolic differences between volar and non-volar skin in mice, revealing distinct amino acid, sugar, and nucleotide metabolism patterns associated with skin type differentiation.
