Recuperación de espermatozoides de la orina en hombres con eyaculación retrógrada [PDF]

Advances in Laboratory Medicine
La eyaculación retrógrada (ER) es la ausencia total o parcial de emisión del esperma, con la consecuente derivación del semen hacia la vejiga durante la fase de emisión de la eyaculación.

Optimization of bovine oocyte cryopreservation: membrane fusion competence and cell death of linoleic acid-in vitro matured oocytes subjected to vitrification [PDF]

Frontiers in Veterinary Science
Long-term conservation of livestock female genetic resources has led to increased interest in oocyte cryopreservation. However, the challenges of preserving large-volume cells and the lack of standardization in vitrification media and cryo-devices for ...

Comparing the Effect of Different Antibiotics in Frozen-Thawed Ram Sperm: Is It Possible to Avoid Their Addition?

Frontiers in Veterinary Science, 2021
It is crucial to perform a deep study about the most extensively used antibiotics in sperm extenders. Most of the protocols and concentrations used in ram are direct extrapolations from other species.

Mass Mortality of Foundation Species on Rocky Shores: Testing a Methodology for a Continental Monitoring Program

Frontiers in Marine Science, 2021
Global concern around substantial losses of biodiversity has led to the development of a number of monitoring programs. Networks were established to obtain appropriate data on the spatial and temporal variation of marine species on rocky shores. Recently,

Epithelial and Neural Cadherin in Mammalian Fertilization: Studies in the Mouse Model

Cells, 2021
Successful mammalian fertilization requires a well-orchestrated sequence of molecular events leading to gamete fusion. Since this interaction involves Ca2+-dependent adhesion events, the participation of the Ca+2-dependent cell-cell adhesion proteins ...

The mechanisms underpinning lateral gene transfer between grasses

PLANTS, PEOPLE, PLANET, Volume 5, Issue 5, Page 672-682, September 2023., 2023
Lateral gene transfer (LGT) refers to the transmission of genetic material without sexual reproduction. LGT is widespread in a number of plant species, including grasses. But how these genes of foreign origin got there is presently unknown. In this review, we show that transformation techniques used to genetically modify organisms could occur in the ...

Modeling genetic benefits and financial costs of integrating biobanking into the conservation breeding of managed marsupials

Conservation Biology, Volume 37, Issue 2, April 2023., 2023
Abstract Managed breeding programs are an important tool in marsupial conservation efforts but may be costly and have adverse genetic effects in unavoidably small captive colonies. Biobanking and assisted reproductive technologies (ARTs) could help overcome these challenges, but further demonstration of their potential is required to improve uptake. We
