The application of fragrant ointments and pigments as a funeral practice in the Guatemalan Petén
Plant and animal molecules non previously identified in Maya mural paintings: First results from Acanceh
Organic compositional analysis of ancient maya tooth sealants and fillings
Chromatic palette studies in sculptural architectonical elements of Maya buildings in the south of Campeche, Mexico
The Maya sites Balamkú, Calakmul, Becán, Chicanná, Xpuhil, Hormiguero, Muñeca, and Chactún are located in the south area of the Mexican State of Campeche, immerse in a tropical subhumid climate. Surrounded by jungle vegetation, these archeological sites preserve some of the best examples of sculptural elements from the pre-Classic (1800 b. C. – 250 a. C.) to the terminal Classic (1000 d. C.) periods. These sites display how the Maya used sculptur…
The hidden web and the fentanyl problem: Detection of ocfentanil as an adulterant in heroin
Something New about Something Old: A 10-Year Follow-Up on Classical and New Psychoactive Tryptamines and Results of Analysis
New psychoactive tryptamines may be a public health risk since they intend to mimic the hallucinogenic effects of regulated psychoactive drugs. Few studies describe uses and clinical effects of unregulated new psychoactive tryptamines. This study aims (1) to explore the presence of tryptamines classified as NPS among the substances delivered for analysis to a harm-reduction organization; (2) to describe the substances found in the samples after a…

Spectrochemical Characterization of Red Pigments Used in Classic Period Maya Funerary Practices
We studied the composition, colour chromaticity and form of application of red pigments in human bone samples from seven C lassic period L owland M aya sites. The samples were analysed by X ‐ray diffraction, scanning electron microscopy ( SEM ) and X ‐ray energy‐dispersive spectroscopy ( EDS ). Colour was measured using conventional colour identification standards ( M unsell) and reflectance spectroscopy. Cinnabar and hematite were identified as …
