Cryopreservation of common carp sperm [PDF]

open access: yes, 2003
Experiments were carried out to investigate the effect of five extenders (sucrose, glucose, fructose, KCl and a saline carp sperm extender) and two cryoprotectants (dimethyl-sulfoxide (DMSO) and methanol) on the cryopreservation of common carp sperm ...

Selection of Cryoprotectant in Lyophilization of Progesterone-Loaded Stearic Acid Solid Lipid Nanoparticles

open access: yesPharmaceutics, 2020
Cryoprotectants are often required in lyophilization to reduce or eliminate agglomeration of solute or suspended materials. The aim of this study was to select a cryoprotecting agent and optimize its concentration in a solid lipid nanoparticle ...

Viability of Toxoplasma gondii in cattle semen cryopreserved with different concentrations of cryoprotectant

open access: yesPesquisa Veterinária Brasileira, 2023
: Toxoplasma gondii can be eliminated in bovine semen. Cryopreserved semen is often used due to the fact that artificial insemination in dairy and beef cattle provides benefits in terms of production.

Cryoprotective Effects of Carrageenan Oligosaccharides on Crayfish (Procambarus clarkii) during Superchilling

open access: yesFoods, 2023
Cryoprotectants are widely used to protect muscle tissue from ice crystal damage during the aquatic products freezing process, but traditional phosphate cryoprotectants may cause an imbalance in the calcium-to-phosphorus ratio for the human body.

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.

Vitrification Solutions for Plant Cryopreservation: Modification and Properties

open access: yesPlants, 2021
Many plants cannot vitrify themselves because they lack glassy state-inducing substances and/or have high water content. Therefore, cryoprotectants are used to induce vitrification.

A new crystal form of penicillin acylase from Escherichia coli [PDF]

open access: yes, 1997
A new crystal form of penicillin acylase (penicillin amidohydrolase, E.C. 3.5.1.11) from Escherichia coli W (ATCC 11105) is reported. The crystals were grown using a combination of hanging-drop and streak-seeding methods.

Equilibrium vitrification of mouse embryos at various developmental stages using low concentrations of cryoprotectants

open access: yesThe Journal of Reproduction and Development, 2021
We previously developed a new vitrification method (equilibrium vitrification) by which two-cell mouse embryos can be vitrified in liquid nitrogen in a highly dehydrated/concentrated state using low concentrations of cryoprotectants. In the present study,

Cryoprotectant enables structural control of porous scaffolds for exploration of cellular mechano-responsiveness in 3D

open access: yesNature Communications, 2019
Despite the wide applications, systematic mechanobiological investigation of 3D porous scaffolds has yet to be performed due to the lack of methodologies for decoupling the complex interplay between structural and mechanical properties. Here, we discover
