Evaluation of Low-density lipoprotein and egg yolk as cryoprotectants non-penetrating of Peruvian Paso horse semen [PDF]
The objective was to evaluate the low-density lipoproteins (LDL) and egg yolk as nonpenetrating cryoprotectants in Peruvian horse semen. Four adult males were collected. Prior to transfer to the laboratory, it was prediluted with dilutor.

Cryopreservation of common carp sperm [PDF]
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 ...

Stepped vitrification technique for human ovarian tissue cryopreservation [PDF]
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.

Polyampholytes as Emerging Macromolecular Cryoprotectants [PDF]
Cellular cryopreservation is a platform technology which underpins cell biology, biochemistry, biomaterials, diagnostics, and the cold chain for emerging cell-based therapies. This technique relies on effective methods for banking and shipping to avoid the need for continuous cell culture.

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

Cryoprotectant-free vitrification of human spermatozoa in new artificial seminal fluid [PDF]
Vitrification is a new method that has been recently introduced in Assisted Reproduction Technique programs. The aim of this study was to design a new medium similar to normal human seminal fluid (SF), formulation artificial seminal fluid (ASF), and to ...

Effects of Permeable Cryoprotectants on Viability of Mammalian Embryo Mo
The objective of this study was to evaluate the toxicities of permeable cryoprotectants and finally to establish the cryopreservation method of surplus embryos obtained during assisted reproductive technology (ART).
