Society Governor, Dr. Serean Adams, was in the news after speaking about the future and challenges facing aquaculture at New Zealand's recent industry conference held in Nelson, New Zealand.

Dr. Adams, who completed her PhD under Cryobiology Editor-in-Chief, Prof. David Rawson, is now Aquaculture Group Manager at Cawthron Institute, New Zealand's largest independent science organisation, specialising in science that supports the environment and development within primary industries.

Miao Zhang Defends Thesis

Miao Zhang Defends Thesis 

MiaoZhangStudent member of the Society for Cryobiology, Miao Zhang, is to defend her thesis on June 23, 2017. During her PhD studies Ms. Zhang received the Society's John K. Critser award for the best extended student abstract in 2015 and the Peter L. Steponkus Crystal award for the best student oral presentation at the Society's meeting in 2016.

Thesis: Towards dry preservation of mammalian cellls
The central aim of this thesis was to test if trehalose can be introduced into mammalian cells during freezing-induced membrane permeabilization and if this subsequently stabilizes cells during freezing and/or freeze-drying. It was hypothesized that membrane-impermeable molecules including trehalose can be loaded into cells through freezing-induced membrane phase transitions. One of the conclusions was that mammalian cells can be loaded with membrane-impermeable compounds (i.e. trehalose) by subjecting the cells to freezing-induced osmotic stress and membrane imperfections. It was shown that trehalose can be used as sole cryoprotectant to cryopreserve cells. Preloading with trehalose via fluid-phase endocytosis did not increase cryosurvival rates if trehalose is also added as extracellular protectant. It is particularly freezing-induced trehalose uptake that facilitates cryosurvival when trehalose is used as the sole cryoprotectant. One other aim was to investigate if freezing-induced uptake of trehalose stabilizes cells during freeze-drying, and to assess the effect of trehalose on storage stability of DNA during freeze-drying and dried storage. No viable cells were recovered after freeze-drying and rehydration. DNA was found to be largely intact directly after freeze-drying. DNA damage in freeze-dried cells progressively increases with storage duration and temperature. DNA damage was prevented by storage of the samples at 4°C. It was shown that trehalose reduces DNA damage during storage.

Biography
Miao Zhang received her education at Southeast University (Nanjing, China) (BE, 2011), after which she completed master's studies at Ulm University (Ulm, Germany) (MSc, 2013). She was accepted in the PhD program ‘Regenerative Sciences’ in 2013 at Hannover Medical School (Hannover, Germany) and conducted her PhD project at the Institute of Multiphase Processes, Leibniz University of Hannover (Hannover, Germany), under the supervision of Dr. Willem Wolkers.

Peter Mazur Memorial Website

Peter Mazur Memorial Website 

Peter_MazurFritz Kleinhans has recently unveiled a memorial website for the late Peter Mazur. Fritz has invited members of the Society for Cryobiology to submit photographs or remembrances for inclusion on the site. 

Peter Mazur (1928-2015) was a pioneer and leading figure in the world of cryobiology for over 50 years. He was a founding member of the Society for Cryobiology and served as President from 1973-1974. He served numerous terms as Governor and was active at board meeting even while not in office (no one argued with Peter!). He was also a member of the editorial board from 1967 until his death.

Close friends and colleagues of Peter's, Fritz Kleinhans and David Pegg, wrote a touching obituary which was published in the April 2016 issue of Cryobiology. The obituary, along with photos and details of Peter's most important research can all be found on the memorial website.
