Cytotoxicity Test for Bioceramics of Calcium Phosphate

Materials Science Forum, 1998
Calcium and phosphor compounds have been used as biomaterials in the medical and odontological field to replace bone tissue. Calcium pyrophosphate (Ca 2 P 2 O 7 ), synthetic hydroxyapatite [Ca 10 (PO 4 ) 6 (OH) 2 ] and natural hydroxyapatite from bovine bone were obtained by powder process, milled and characterized by chemical and crystallographic ...

Robust chemical bonding of PMMA microfluidic devices to porous PETE membranes for reliable cytotoxicity testing of drugs.

Lab on a Chip, 2019
Here, we report a simple yet reliable method for bonding poly(methyl methacrylate) (PMMA) to polyethylene terephthalate (PETE) track-etched membranes using (3-glycidyloxypropyl)trimethoxysilane (GLYMO), which enables reliable cytotoxicity tests in a ...

Testing for food allergy: A statistical comparison of cytotoxic and intracutaneous tests

The Laryngoscope, 1978
AbstractThis study presents a comparison of in vitro cytotoxic food allergy test results with those of in vivo intracutaneous food allergy testing by both objective serial dilution titration and subjective provocation. During the study the cytotoxic test was utilized as a screening device for follow‐up Lee intracutaneous testing, the latter providing ...

Low Cytotoxicity and Genotoxicity of Two-Dimensional MoS2 and WS2.

ACS Biomaterials Science & Engineering, 2016
Atomically thin transition-metal dichalcogenides (TMDs) have attracted considerable interest because of their unique combination of properties, including photoluminescence, high lubricity, flexibility, and catalytic activity.

Tests Predictive of Cytotoxic Activity

1974
Tests predictive of cytotoxicity are of three general types; those that select agents for antitumor cytotoxicity, those that predict host cytotoxicity, and those applied to predict the toxicity/benefit ratio of a drug of generally accepted potency in a particular patient with a specific tumor.

Cytotoxicity Testing for Food Safety Evaluation

1995
We have been interested in studying the factors affecting the quality of food. It is important to detect toxic substances in foods as well as to control food-born disease microorganisms. We have been applied in vitro bioassay to evaluate the quality of food.

Cytotoxicity Testing for Evaluating Food Safety

2005
Different cytotoxicity tests are used to determine food safety. We propose rapid cytotoxicity testing based on menadione-catalyzed H2O2 production by viable cells, which depends on both intracellular NAD(P)H concentration and plasma membrane-bound quinone oxidoreductase (EC 1.6.99.2).
