Post-transplant, a low peak creatinine, combined with a relatively short recovery time to normal creatinine, suggest the kidneys were minimally damaged by the cryoprotection protocol, and much (or all) of that damage was quickly repaired once transplanted into an otherwise healthy animal.
This forced the team to perform Matheryn's cryoprotection in Thailand before shipping her body to America.
8220;Hyperquenching technology promises to address a major source of irreproducibility influencing X-ray diffraction outcomes, to simplify the identification of satisfactory cryoprotection conditions, and to increase the throughput of structure-solving pipelines,” says Robert Thorne, Chairman and CTO of MiTeGen.
Diapause metabolism and changes in carbohydrates related to cryoprotection in Pieris brassicae.
We collected the brains and postfixed them for 24 h in 4 percent paraformaldehyde followed by cryoprotection in 30 percent sucrose in PBS overnight.
After complete perfusion the brains were removed and post-fixed for 4 h at room temperature in plastic containers filled with the same fixative solution; for cryoprotection the fixed brains were immersed in 15% sucrose (in phosphate buffer at room temperature) for 24h, followed by 30% sucrose for another 24 h, and stored at -70[degrees]C until further use.
Following the cryoprotection, every alternate 30 [micro]m thick section of the rat brain was taken from -3.
Plant vitrification solution 2 lowers water content and alters freezing behaviour in shoot tips during cryoprotection.
However, the cryoprotection profiles of glycine and cysteine were dosage dependent.
The control of water content of plant samples before freezing was the key factor in developing successful cryoprotection protocols as previously reported.
Dr Atsuo Ogura, from the Institute of Physical and Chemical Research in Ibaraki, Japan, said the freezing procedure did not involve hi-tech cryoprotection.
The freezing procedure involved no hi-tech cryoprotection, said the Japanese scientists, led by Dr Atsuo Ogura from the Institute of Physical and Chemical Research in Ibaraki.
