Journal ArticleDOI

Guidelines for the use and interpretation of assays for monitoring autophagy (3rd edition)

Daniel J. Klionsky, +2522 more
- 21 Jan 2016 - 
TL;DR: In this paper, the authors present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macro-autophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes.
Journal ArticleDOI

Antioxidant supplementation in vitro improves boar sperm motility and mitochondrial membrane potential after cryopreservation of different fractions of the ejaculate.

Fernando J. Peña, +4 more
- 15 Sep 2003 - 
TL;DR: In the present trial, exogenous Trolox positively affected post-thaw sperm viability (as motility and mitochondrial membrane potential) in both fractions of the ejaculate.
Journal ArticleDOI

Assessment of fresh and frozen-thawed boar semen using an Annexin-V assay: a new method of evaluating sperm membrane integrity.

Fernando J. Peña, +3 more
- 01 Sep 2003 - 
TL;DR: The finding that fewer spermatozoa in Portion I of the ejaculate showed early apoptosis post-freezing, suggests boar spermatozosa in this portion of the seminal plasma are less sensitive to the stress induced by cryopreservation.
Journal ArticleDOI

Detection of "apoptosis-like" changes during the cryopreservation process in equine sperm.

Cristina Ortega-Ferrusola, +7 more
- 19 Sep 2007 - 
TL;DR: It is proposed that sperm mitochondria may be directly involved in the subtle damage that is present in most spermatozoa surviving freezing and thawing.
Journal ArticleDOI

Lipid peroxidation, assessed with BODIPY-C11, increases after cryopreservation of stallion spermatozoa, is stallion-dependent and is related to apoptotic-like changes

C. Ortega Ferrusola, +7 more
- 01 Jul 2009 - 
TL;DR: This LPO is unlikely to represent, per se, a sign of cryopreservation-induced injury, but it is apparently capable of triggering 'apoptotic-like changes' that could result in the sub-lethal cryodamage often seen among surviving spermatozoa.
