Article Synopsis
  • A study was conducted to investigate the presence of mineralocorticoids and glucocorticoids, particularly focusing on aldosterone and 18-hydroxycorticosterone, in hair follicles, which has not been reported before.
  • Hair samples from 15 healthy volunteers were analyzed using advanced extraction and mass spectrometry techniques, allowing for the detection of various steroids without significant differences between genders.
  • Notable findings included the detection of deoxycortisol, deoxycorticosterone, and 18-hydroxycorticosterone for the first time in hair, showing variability in levels for some steroids but stability in others across individuals.

We present a tool for multi-omics data analysis that enables simultaneous visualization of up to four types of omics data on organism-scale metabolic network diagrams. The tool's interactive web-based metabolic charts depict the metabolic reactions, pathways, and metabolites of a single organism as described in a metabolic pathway database for that organism; the charts are constructed using automated graphical layout algorithms. The multi-omics visualization facility paints each individual omics dataset onto a different "visual channel" of the metabolic-network diagram.

The classical androgens, testosterone and dihydrotestosterone, together with dehydroepiandrosterone, the precusrsor to all androgens, are generally included in diagnostic steroid evaluations of androgen excess and deficiency disorders and monitored in androgen replacement and androgen suppressive therapies. The C11-oxy androgens also contribute to androgen excess disorders and are still often excluded from clinical and research-based steroids analysis. The contribution of the C11-oxy androgens to the androgen pool has not been considered in androgen deficiency.

Toxoplasma gondii is a food-borne zoonotic parasite widespread in a variety of hosts, including humans. With a majority of infections in Europe estimated to be meat-borne, pork, as one of the most consumed meats worldwide, represents a potential risk for consumers. Therefore, we aimed to investigate the progress of T.
