TLDR
This chapter describes selected assays for the evaluation of cellular viability and proliferation of cell cultures using the formation of the omnipresent reducing agents NADH and NADPH as a marker for metabolic activity in the following assays.Abstract:
This chapter describes selected assays for the evaluation of cellular viability and proliferation of cell cultures. The underlying principle of these assays is the measurement of a biochemical marker to evaluate the cell’s metabolic activity. The formation of the omnipresent reducing agents NADH and NADPH is used as a marker for metabolic activity in the following assays. Using NADH and NADPH as electron sources, specific dyes are biochemically reduced which results in a color change that can be determined with basic photometrical methods. The assays selected for this chapter include MTT, WST, and resazurin. They are applicable for adherent or suspended cell lines, easy to perform, and comparably economical. Detailed protocols and notes for easier handling and avoiding pitfalls are enclosed to each assay.read more

Toxicological assessment of nanomaterials: the role of in vitro Raman microspectroscopic analysis.
TL;DR: 3D toxicity plots of spectral markers, as a function of time and dose, are introduced as new methodology for toxicological analysis based on the intrinsic properties of the biomolecular changes, such as cytoplasmic RNA aberrations, protein and lipid damage associated with the toxic response.

TL;DR: In vitro and in vivo data of Bz-SEDDS showed that the incorporation of BZ into SEDDS does not alter its potency, efficacy and safety, and can be a more practical and personalized orally administered liquid dosage form compared to suspension of crushed BZ-tablets to treat newborn and young children by emulsifying SED DS in different aqueous liquids with advantage of dosing flexibility.

TL;DR: It is demonstrated that high glucose concentrations triggered glyco-oxidative stress in intestinal cells; the downregulation of PON2 could result in a higher oxidative stress and might contribute to intestinal dysfunction.
Journal ArticleDOI
Cytotoxicity of acetylcholinesterase reactivators evaluated in vitro and its relation to their structure.
TL;DR: The results show that at least five structural features affect the reactivators’ toxicity such as the number of oxime groups in the molecule, their position on pyridinium ring, the length of carbon linker, and the oxygen substitution or insertion of the double bond into the connection chain.

Synchronization of Plasmodium falciparum erythrocytic stages in culture.
TL;DR: Synchronous development of the erythrocytic stages of a human malaria parasite, Plasmodium falciparum, in culture was accomplished by suspending cultured parasites in 5% D-sorbitol and subsequent reintroduction into culture.

Quantitative assessment of antimalarial activity in vitro by a semiautomated microdilution technique.
TL;DR: A rapid, semiautomated microdilution method was developed for measuring the activity of potential antimalarial drugs against cultured intraerythrocytic asexual forms of the human malaria parasite Plasmodium falciparum, and results demonstrated that the method is sensitive and precise.

Neutral red uptake assay for the estimation of cell viability/cytotoxicity.
TL;DR: The neutral red uptake assay provides a quantitative estimation of the number of viable cells in a culture and is cheaper and more sensitive than other cytotoxicity tests (tetrazolium salts, enzyme leakage or protein content).

Simple and Inexpensive Fluorescence-Based Technique for High-Throughput Antimalarial Drug Screening
TL;DR: A side-by-side comparison of this new fluorescence assay and a standard radioisotopic method suggest that it may be an ideal method for high-throughput antimalarial drug screening.
