Insect Freezing Protection in Pterostichus brevicornis (Carabidae)
Nature New Biology, 1972THERE are conflicting opinions concerning the mechanisms of freezing protection and survival in adult insects1, 2 generally resulting from a lack of consideration of pre-experimental conditions (that is, temperature exposure) or inappropriate analytical procedures.

Host cadavers protect entomopathogenic nematodes during freezing
Journal of Invertebrate Pathology, 2002The entomopathogenic nematodes Heterorhabditis bacteriophora, Steinernema carpocapsae, Steinernema glaseri, and Steinernema feltiae were exposed to freezing while inside their hosts. Survival was assessed by observing live and dead nematodes inside cadavers and by counting the infective juveniles (IJs) that emerged after freezing.

Novel preservation condition without ultra-low temperature is needed for the study of pathogen in marine fishes. Freeze-drying is such a method usually used for preservation of terrigenous bacteria. However, studies using freeze-drying method to preserving marine microorganisms remain very limited.

Passive freeze protection for solar collectors
Solar Energy, 1975Freeze damage is an important practical problem for water-type solar collectors. This note describes a simple passive concept that can be used to protect water-type solar collectors from freeze damage. Briefly, the water is allowed to freeze. As it freezes, however, it expands against a compliant region, and thus, the expansion does not damage the ...

Radiation Protection by a Number of Substances Preventing Freezing Damage
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1965Intraperitoneal injections of 1 ml 20 per cent propylene glycol, 1·5 ml 10 per cent ethanol and 0·8 ml 30 per cent glucose reduced 30-day mortality in mice subjected to whole-body irradiation. Dose-reduction factors of about 1·25 were obtained with propylene glycol and ethanol respectively. The protection lasted for about 1-2 hours. Some estimations of

Pretreatment with protective substances as a factor in freeze-thaw survival
Cryobiology, 1965Abstract Transplantation of 246 venter to dorsum autografts was used to evaluate freeze-thaw survival of mouse skin with respect to pretreatment with glycerol and dimethyl sulfoxide (DMSO). It was concluded that 1) DMSO was at least as protective and toxic as glycerol, 2) loss of transplants which occurred was due to pretreatment prior to freezing ...

Mode of Protection with Polyvinylpyrrolidone in Freezing of Bone Marrow
Nature, 1962THE accepted concept of the action of protective compounds in low-temperature preservation of cells maintains that a small molecular size of the additive is essential to allow its penetration into the cell1,2. A previous investigation by us3, however, demonstrated that polyvinylpyrrolidone (PVP, 30,000 mol.
