In vivo Testing of a Biostable Polyurethane
Journal of Biomaterials Applications, 1991At present all the commercially available "medical grade" urethane elastomers exhibit a phenomenon known as environmental stress cracking (ESC). This phenomenon is characterized by surface microcracking when the elastomer is elongated while in vivo. The degree of strain that is required to initiate microcracking varies from composition to composition ...

In-vivo Testing of Polymers for Thrombogenicity
Biomaterials, Medical Devices, and Artificial Organs, 1974A brief review of the methods established for the thrombogenicity testing of materials to be used in cardiovascular devices is given. A modified version of the Gott canine inferior vena cava test is described along with test results for 10 polymeric and carbonaceous materials.

Testing of retinoids for teratogenicity in vivo
1990Publisher Summary Retinoids are powerful teratogens that induce specific malformation patterns in animals as well as in humans. For testing the teratogenic potential of a large number of new retinoids in vivo , treating rats once on Day 9 of gestation has been suggested.

Mutagenicity tests with astemizole in vitro and in vivo
Archives of Toxicology, 1982Possible induction of chromosomal aberrations and/or sister chromatid exchanges by astemizole was studied in vitro on human lymphocytes. In vivo chromosomal damage was assessed by a micronucleus test on rats and a dominant lethal test on both male and female mice.

1975
In addition to an analysis of error sources and their influence on the accuracy of the result as will be given in Chapter XI, in vivoexpetiments are necessary. Besides the overall testing of the system, especially of the time programming by microcomputer, the effects of the geometric model fit and the interindividual variability have to be established ...

JAMA: The Journal of the American Medical Association, 1981
To the Editor.— A 28-year-old woman with paroxysmal nocturnal hemoglobinuria (PNH) had a 5-cm cutaneous infarction and slough develop after the subcutaneous injection of meperidine (Demerol) hydrochloride for painful crisis. Noting that injectable meperidine may be provided at a pH as low as 3.5, 1 we wondered whether an injection placed close to a ...

“In Vivo” Emotive Imagery: A Preliminary Test
Perceptual and Motor Skills, 1974The process of focusing on positive covert events during overt anxiety-arousing situations has been termed “in vivo” emotive imagery. 36 Ss were stratified on sex, given imagery training, and then assigned randomly to no-treatment control, distraction control, or experimental treatment conditions during which they were asked to immerse their hands in ...

In vivo tests for antimycotic drugs.
Chemioterapia : international journal of the Mediterranean Society of Chemotherapy, 1985Authors emphasize the pathogenetic importance of fungous dimorphism and its consequence in the usefulness of antimycotic drugs. For the study of drugs' activity on C. albicans, two models for the evaluation on yeast or mycelial form were developed.

In vivo test of inductively powered neurostimulator
2017 International Symposium on Micro-NanoMechatronics and Human Science (MHS), 2017In this paper, a wireless powered neurostimulator was fabricated using a magnetic field resonance method. The power to stimulate peripheral nerve was supplied from a transmitter coil to a receiver coil which is connected to a peripheral nerve. In vivo test was conducted by stimulating a rat sciatic nerve using fabricated neurostimulator, and the motion
