Scalp hair was collected by cutting a lock of hair close to the skin in the occipital or vertex region of the head; body hair was shaved with a disposable razor. Only the proximal 5 cm segment was examined or – if the hair length was less than 5 cm—the entire length of the lock of scalp hair or the body hair sample, respectively. Drug-free hair
The analysis of drug in hair continues to be a useful tool in many fields of clinical and forensic toxicology and has substantially evolved over the last two decades . Modern mass spectrometers (MS), particularly tandem MS, can detect concentrations in the low pg/mg range (like those observed in hair samples) that were previously not possible.
Acute Toxicity and Genotoxic Activity of Avocado Seed Extract (Persea americana Mill., c.v. Hass) ...

The crude extracts and active compounds of BAA have been reported to exert a wide range of pharmacological activities, such as antitumor, anti-inflammatory, antiviral, herbicidal, and insecticidal activities. Although BAA is safe when administered at a conventional dose, at higher doses, it exhibits toxicity due to the presence of quassinoids.
Hair Analysis in Clinical and Forensic Toxicology is an essential reference for toxicologists working with, and researching, hair analysis. The text presents a review of the most up-to-date analytical methods in toxicological hair analysis, along with state-of-the-art developments in the areas of hair physiology, sampling, and pre-treatments ...

The purpose of this paper was to provide a systematic and comprehensive overview on the traditional usages, botany, phytochemistry, pharmacology, pharmacokinetics and toxicology of this plant. Furthermore, the possible development trends and perspectives for future research on this medicinal plant are also discussed.
The toxicity of aloin was evaluated in human Jurkat T lymphocytes using flow cytometry and microscopy. Aloin treatment resulted in decreased cell size, increased granularity, a block at the G2/M phase of the cell cycle, and loss of both membrane integrity and mitochondrial membrane potential in a dose-dependent manner, suggesting a ...
Biotin is unlikely to cause adverse events, even when taken in high dosages. There are no documented cases of biotin overdose and toxicity studies have shown doses up to 600 times the recommended daily intake do not cause signs of toxicity. Biotin supplementation, at high doses, may interfere with a variety of lab tests.
