Summary: Hair is a good bioindicator for exposure, especially when hair dyes are used. This study successfully validated an analytical method for determining bismuth, cadmium, lead, and silver in scalp human hair. The results showed higher silver concentration in dyed hair, indicating bioaccumulation of this element. Associations between metal concentrations and variables such as age, education, smoking habit, dye brand, and use of dietary supplements were observed. The compliance of several commercial hair dye brands with cosmetic regulations was also analyzed.

Summary: In this paper, a novel echo state network with multiple delayed outputs (MDO-ESN) is proposed for time series prediction. The delayed characteristics of output signals are studied to adaptively adjust the output equation of MDO-ESN. A sufficient condition is given to ensure the stability of MDO-ESN. Furthermore, a parameter optimization method is provided to reduce the dependence of prediction accuracy on reservoir parameters. The effectiveness of MDO-ESN is demonstrated through numerical and actual simulation examples.

Summary: Recovering identifiable fingerprints from fired cartridge cases is challenging. Chemical modifications and their effects on fingerprint integrity after firing were investigated in this study. Primary fingerprint lipids were extracted from fired and unfired cartridge cases and quantified using gas chromatography coupled with mass spectrometry. Most lipids showed similar concentrations in fired and unfired cases, except for squalene which had a 28% lower recovery rate in fired cases.

Summary: This study analyzed 43 commercially acquired samples of St. John's wort using paper spray ionization mass spectrometry (PS-MS). It was found that 52.3% of the samples were adulterated with other plant species, including Ageratum conyzoides and Senna spectabilis. Only 13 out of 35 samples produced in Brazil were deemed authentic. Therefore, there is a clear need to improve the quality control of these drugs in Brazil.

Summary: The study aimed to characterize chemical elements and cytotoxicity of two different trademarked Carnoy's solution products (NCS and ICS) using ICP-MS and HaCaT cultures. ICS had lower concentrations of 12 chemical elements than NCS, and was more cytotoxic at T0 and T2. Further investigations into individual compositions of Carnoy's solution formulations are suggested.

Summary: The Mundau lagoon in Maceio, AL, is socially, economically, and culturally significant, but faces issues such as intense anthropic occupation and industrial activities, leading to water pollution and high concentrations of certain elements. Studies show elevated levels of elements in water samples, leading to classification of water as highly impure and polluted, with the main food source sururu containing mercury. Chemometric evaluation indicates distinct chemical profiles at different sampling points.
