Stepped vitrification technique for human ovarian tissue cryopreservation [PDF]

open access: yes, 2019
The advantage of stepped vitrification (SV) is avoiding ice crystal nucleation, while decreasing the toxic effects of high cryoprotectant concentrations. We aimed to test this method for human ovarian tissue cryopreservation.

Effect of Cryopreservation on the Ex Vitro Establishment of Olive Plants Regenerated via Somatic Embryogenesis

open access: yesPlants, 2021
Cryopreservation is considered the best technique for the safe, long-term conservation of embryogenic cultures. However, before integrating it into a somatic embryogenesis system, the influence of cryopreservation on the final production of plants should

Role of Viral Infections in Testicular Cancer Etiology: Evidence From a Systematic Review and Meta-Analysis

open access: yesFrontiers in Endocrinology, 2019
The most represented histotype of testicular cancer is the testicular germ-cell tumor (TGCT), both seminoma and non-seminoma. The pathogenesis of this cancer is poorly known.

Cryopreservation of Algae

open access: yes, 2020
Cryopreservation has been successfully used in the banking and maintenance of cultures of microorganisms, from bacteria to yeasts, since the onset of cryobiology. Biobanking of marine biological resources is crucial for development of scientific knowledge as researchers rely on guaranteed access to reliable, stable resources. Culture collections play a

Vitrification of human immature oocytes before and after in vitro maturation: a review [PDF]

open access: yes, 2017
The use of immature oocytes subjected to in vitro maturation (IVM) opens interesting perspectives for fertility preservation where ovarian reserves are damaged by pathologies or therapies, as in PCO/PCOS and cancer patients. Human oocyte cryopreservation
