MODELING OF THE KINETICS OF CRYOGENIC FREEZING OF LIMA BEAN SEEDS AS A FUNCTION OF INITIAL WATER CONTENT [PDF]

open access: yesEngenharia Agrícola
Cryopreservation is a technique used to preserve genetic material at ultra-low temperatures in cryogenic germplasm banks. In order to enable the cryopreservation of a seed, it is necessary to study its appropriate freezing temperature and its water ...

Cryopreservation of single-sperm: where are we today?

open access: yesReproductive Biology and Endocrinology, 2020
Background Patients with severe oligospermia and nonobstructive azoospermia have very limited numbers of viable sperm in their epididymal and testicular samples. Thus, cryopreservation of their sperm is performed to avoid repeated sperm retrievals and to

Cryopreservation of Pike Perch Sperm in Hatchery Conditions [PDF]

open access: yes, 2008
Experiments were carried out on pike perch (Sander lucioperca L.) to find a method for stripping sperm without contamination by urine, to determine sperm concentration, and to fertilize large batches of eggs with cryopreserved sperm.

Cryopreservation impairs 3-D migration and cytotoxicity of natural killer cells

open access: yesNature Communications, 2020
Natural killer (NK) cells are important effector cells in the immune response to cancer. Clinical trials on adoptively transferred NK cells in patients with solid tumors, however, have thus far been unsuccessful. As NK cells need to pass stringent safety

The Current Trends in Using Nanoparticles, Liposomes, and Exosomes for Semen Cryopreservation

open access: yesAnimals, 2020
Simple Summary Long-term preservation of semen is a pivotal step for artificial insemination in most farm animal species, but it is associated with cellular insults at the cell membrane and cytoskeleton level as well as the generation of reactive oxygen ...

Development of Islet Cryopreservation for Type 1 Diabetes Cell Therapy

open access: yesZhileng xuebao, 2021
In recent years, cell therapy technology for type 1 diabetes has advanced rapidly, but the lack of donor pancreatic islets and the time and space mismatch between donor and recipient limits its clinical application. Cryopreservation technology provides a

Cryopreservation techniques and their application in vegetatively propagated crop plants in Finland

open access: yesAgricultural and Food Science, 2008
Cryopreservation protocols have been introduced as techniques for germplasm preservation of vegetatively propagated horticultural and staple food crops. In Finland, cryopreservation has been studied since 1990’s, beginning with cryopreservation of forest
