Green analytical methods [PDF]

Analytical and Bioanalytical Chemistry, 2012
In 1995 an analytical journal published the first small issue on green analytical chemistry entitled “Environmentally conscientious analytical chemistry”, which was devoted to environmental deleterious side effects of analytical methods, thus indicating that, in spite of the great advances in automation, miniaturization, and alternative sample ...

State‐of‐the‐art electrochemistry for the assessment of oxidative stress and integral antioxidant activity of biological environments

Electrochemical Science Advances, 2023
The present review focuses on the interplay between electrochemistry and life, events on the border of electrochemistry‐biology‐life science, electrochemistry as the basis, and the information source on oxidative stress (OS) or Red/Ox state of biological

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...
