Bisphenol A levels are negatively correlated with serum vitamin D-binding protein and sex hormone-binding globulin levels in women with polycystic ovary syndrome: a pilot study.
This pilot study aimed to determine the relationships between serum VDBP, vitamin D, SHBG, and BPA levels in women with PCOS. Expand
Identification of novel psychoactive substances 25B-NBOMe and 4-CMC in biological material using HPLC-Q-TOF-MS and their quantification in blood using UPLC-MS/MS in case of severe intoxications.
The analytical procedure includes rapid and selective method for the extraction and determination of 4-CMC and 25B-NBOMe in blood samples using UPLC-MS/MS technique and is the first report, that involves a fully validated method for quantification of new-designer drug - 4- CMC in postmortem blood samples.

Troubleshooting of the determination of bisphenol A at ultra-trace levels by liquid chromatography and tandem mass spectrometry
It was concluded that BPA, present in the components of the mobile phase, is being enriched in the front of the separation column during its conditioning, which significantly improved the precision of determination of BPA at low concentration levels. Expand
Daily diet containing canned products significantly increases serum concentrations of endocrine disruptor bisphenol A in young women.
Evaluated serum BPA concentrations in young women after 7 days of dietary exposure to canned products that are a source of this EDC in daily life, which is far lower than the previous tolerable daily intake. Expand
The potential role of bisphenol A in the pathogenesis of polycystic ovary syndrome
This paper presents the results of a clinical and experimental study of endocrinology, diabetology and Isotope Therapy at the National Institute of Tropical and Maritime Medicine, Medical University of Wroclaw. Expand
LC-MS and LC-NMR as Complementary Techniques for the Determination of Pharmaceuticals in Dosage Formulations
Pharmaceuticals contain not only pharmacologically active compounds but also a range of excipients. The danger exists that impurities may also be present in such drugs, which may adversely affectExpand
Bisphenol A impacts hormonal profile in patients with polycystic ovary syndrome but not in healthy women
The purpose of this study was to determine serum bisphenol A (BPA) concentrations using the high-performance liquid chromatography method combined with tandem mass spectrometry in women withExpand
Determination of impurities in pharmaceutical products using LC-MS
Pharmaceutical products can be contaminated by residues of solvents, reagents (used for the synthesis) or degradation products. Impurities in drug may pose a risk to human health and life, thereforeExpand
