25. Dry preservation of biological therapeutics

Cryobiology, 2013
The fields of tissue engineering, cellular therapeutics, and transfusion medicine have matured considerably over the past decade, thus accelerating the need for cost-effective preservation methods to enable the ready supply of biological therapeutics. The current state of the art for preserving biological samples is by cryopreservation, either by slow ...

Physical Preservation Methods for Biological Material

Proceedings, annual meeting, Electron Microscopy Society of America, 1972
This review will be limited to physical preservation methods involving freezing, and will include discussion of freeze-drying, freeze-substitution, ultracryomicrotomy and freezeetching. Pre-treatment and freezing steps can be considered as common to all techniques.The most common pre-treatment is soaking in a cold 20% glycerol solution to provide ...

Can Purifying Natural Selection Preserve Biological Information?

Biological Information, 2013
Most deleterious mutations have very slight effects on total fitness, and it has become clear that below a certain fitness effect threshold, such low-impact mutations fail to respond to natural selection. The existence of such a selection threshold suggests that many low-impact deleterious mutations should accumulate continuously, resulting in ...

PRESERVATION OF BIOLOGICAL MATERIALS BY FREEZEDRYING

1964
Abstract : The feasibility of freeze-dehydrating biological materials by extracting frozen moisture with dry cryogenic liquids in the presence of dessicants was investigated. Freeze-dehydration of hydrated gelatin capsules in liquid nitrogen and liquid nitrous oxide proceeded too slowly to be evaluated. Dehydration was feasible in ethyl ether and ethyl

Merthiolate As a Preservative for Biological Products

The Journal of Immunology, 1933
Abstract Introduction. Previous to the fall of 1931 this laboratory produced diphtheria toxoid by formolizing diphtheria toxin having the usual range in potency values. The minimum values of such toxin was that set forth by the National Institute of Health, namely, of an L + value of 0.2 cc. and an m.l.d. value of 0.0025 cc., and maximum

Dental Implants Biological Complications: Tooth Preservation Reevaluated

2019
A common dilemma encountered by dental practitioners is the decision whether to extract a compromised natural tooth and replace it with a dental implant, or to attempt preservation of the natural tooth by endodontic periodontal and restorative treatments.
