The authors suggested a method of gas chromatography for detection of toluylene diisocyanate (TDI) in biologic material: liver, lungs, spleen, brain, kidney. The method includes TDI extraction from tissues by solvent, subsequent concentration and the extract chromatography by a device with electron capture detector. The method was tested in white rats.

Three endophytic strains, Phomopsis sp., Fusarium proliferatum, and Tinctoporellus epimiltinus, isolated from various plants in the rainforest of the Philippines, were investigated regarding their ability to repress growth of the pathogenic fungus Colletotrichum musae on banana fruits causing anthracnose disease. An in vitro plate-to-plate assay and an in vivo sealed box assay were conducted, using commercial versus natural potato dextrose medium (PDA).

The detection of endogenous anabolic androgenic steroids (EAAS) is performed with the Steroidal Module of the Athlete Biological Passport (ABP). Glucocorticoids (GC) could be a confounding factor to the ABP Steroidal Module because they inhibit the hypothalamic-pituitary-adrenal axis, and ABP metabolites have partial adrenal origin. In previous studies, single-dose systemic GC administrations have been shown to reduce the urinary ratios A/T and 5αdiol/E.
