Comet candidates among quasi-Hilda objects
(EDP Sciences, 2016-05)
We present the results of a search for quasi-Hilda comets. We wanted to find objects that have recently arrived from the Centaur zone that could became active near the perihelion of their orbits. Methods. Two hundred and ...
Physical and dynamical characterization of (5201) Ferraz-Mello, a possible extinct Jupiter family comet
(EDP SCIENCES S A, 2008)
Context. The subject of asteroids in cometary orbits (ACOs) has been of growing interest lately. These objects have the orbital characteristics typical of comets, but are asteroidal in appearance, i.e., show no signs of a ...
Stability in the most external region of the Oort Cloud: evolution of the ejected comets
(Oxford University Press, 2019-10)
In this paper, we present a study of the dynamical effects of the Galaxy on the external region of the Oort Cloud. Theaimsofthispaperare: (i) to determine an outer limit for the Oort Cloud; and (ii) to analyse the dynamical ...
Mutagenicity and antimutagenicity of (-)-hinokinin a trypanosomicidal compound measured by Salmonella microsome and comet assays
(Biomed Central Ltd., 2012-10-31)
Background: The dibenzylbutyrolactone lignan (-)-hinokinin (HK) was derived by partial synthesis from (-)- cubebin, isolated from the dry seeds of the pepper, Piper cubeba. Considering the good trypanosomicidal activity ...

Evaluation of genotoxicity of general anesthesia maintained with desflurane in patients under minor surgery
(2016-05-01)
There is controversy over the genotoxic effects of volatile anesthetics. The available literature on the genotoxicity of desflurane, one of the newest volatile halogenated agents used for general anesthesia maintenance, ...
