Reduction of percutaneous absorption of toxic chemicals by dendrimers
Cutaneous and Ocular Toxicology, 2009Polyamidoamine (PAMAM) dendrimer, a reactive nanoparticle, was investigated as a potential protectant against percutaneous absorption of chemicals. Permeation of furfural (model toxicant) through rat skin from a 1-mg/mL solution was studied in the absence and presence of PAMAM dendrimer, which was applied either as 1, 4, and 6 mg/mL in furfural ...

Chemical Sound Absorption in the Sea
1981Chemical relaxations have been shown to be responsible for the excess sound absorption observed in ocean propagation measurements. Although a great number of processes occur in sea water, only two account for most of the absorption in the frequency range of interest.

Chemical modification in electrothermal atomic absorption spectrometry
1998Advances in chem. modification electrothermal at. absorption spectrometry (ETAAS) are reviewed with an emphasis on the progress made after the publication of the previous extensive review (Tsalev et al., Spectrochim. Acta Rev. 1990, 13, 225). Among the topics discussed are the useful effects, drawbacks, and limitations of chem.

Multitask learning for predicting pulmonary absorption of chemicals
Food and Chemical ToxicologyPulmonary absorption is an important route for drug delivery and chemical exposure. To streamline the chemical assessment process for the reduction of animal experiments, several animal-free models were developed for pulmonary absorption research. While Calu-3 and Caco-2 cells and their derived computational models were used in estimating pulmonary ...

Chemical Aspects of Atomic Absorption
1969The phenomenal growth of atomic absorption spectrometry in the past twelve years can be attributed to many factors such as the high sensitivity of the method for a large number of elements, advances in overcoming interferences, saving of time required for analysis, and the rapid improvement of instrumentation.

Systematic Absorption of Chemicals and Their Kinetics
2017Chemicals applied to skin surface can be absorbed into the systemic circulation and delivered to the whole body, often resulting in systemic pharmacological or toxicological responses. Because a relationship exists between the chemical concentration at the site of action and a given response, it is important to know the change in the chemical ...
