Drug Testing and Analysis, EarlyView.A total of 3378 self‐reported treated and untreated hair samples were analyzed for PTCA and PTeCA by LC‐MS/MS. Moreover, their in vitro formation was assessed in 225 untreated hair by different cosmetic treatments with and without oxidative agents. Data suggest that PTeCA could be a reliable marker for oxidative cosmetic treatments in hair.

Drug Testing and Analysis, EarlyView.ABSTRACT Hair analysis is increasingly used in forensic toxicology; however, result interpretation may be influenced by cosmetic hair treatments. Although the effects of bleaching, dyeing, and thermal straightening have already been evaluated, data on permanent chemical hair straightening are scarce, particularly under in vivo conditions.

Segmental Hair Analysis of Diphenhydramine and Cyclizine Following a Single Dose
Drug Testing and Analysis, EarlyView.A single oral dose of diphenhydramine and cyclizine can be quantified in human head hair for a minimum of 5 months and, in certain cases, for up to 1 year following intake. Among 12 study participants, the measured concentrations ranged from 0 to 610 pg/mg within 1 year post‐intake.

Developmental Dynamics, EarlyView.Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Developmental Dynamics, EarlyView.Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

Covalently Bonded S‐Scheme Polymer Heterojunction for Highly Efficient Solar Hydrogen Evolution
EcoEnergy, EarlyView.A covalently integrated all‐organic S‐scheme heterojunction (B‐CN2@Py‐CN) establishes atomic‐level charge transport channels and a strong built‐in electric field, enabling exceptional charge separation efficiency. This molecularly engineered photocatalyst achieves a cocatalyst‐free hydrogen evolution rate of 27.9 mmol g−1 h−1 under visible light ...

Pulp Bleaching and Bleaching Effluents
2013In Kraft pulping, about 90–95 % of wood lignin gets solubilized during the cooking process. The remaining 5–10 % of lignin is responsible for the brown color of the Kraft pulp and unbleached paper. The objective of bleaching is to remove the residual lignin from the pulp as selectively as possible, without degrading the pulp carbohydrate, especially ...
