Biologically-oriented Alveolar Ridge Preservation

Minerva Dental and Oral Science, 2023
A recent systematic review failed to identify one approach for alveolar ridge preservation with superior outcomes. The present case series aimed to evaluate the dimensional changes of sites undergoing Biologically-oriented Alveolar Ridge Preservation (BARP).The sockets were filled with a collagen sponge up to 4-5 mm from the most coronal extensions of ...

Preservation of biological materials under desiccation

Critical Reviews in Food Science and Nutrition, 1997
A number of life forms, including seeds, certain nematodes, bacterial and fungal spores, and cysts of certain crustaceans, show an ability to survive desiccation. The present article reviews the literature available on this subject and critically evaluates the evidence for various mechanisms that may be responsible for these phenomena.

Debating the biological reality of modelling preservation

International Journal of Food Microbiology, 2002
Predictive food microbiology is a rapidly developing science and has made great advances. The aim is to debate a number of issues in modelling preservation: (1) inoculum and prehistory effects on lag times and process susceptibility; (2) mechanistic vs. empirical modelling; and (3) concluding remarks (the Species concept, methodology and biovariability)

Protein stability in preserved biological remains

International Journal of Biochemistry, 1971
Abstract 1. 1. A sample of whole human blood that had been stored in the dried state for 8 years at room temperature was tested for the presence of eleven specific globular proteins. 2. 2. Eight of them survived, as judged by the criteria of enzymatic activity and reactivity with specific antiscra. 3. 3.

Interstellar Medium Has Biological Preservative

Physics Today, 1969
Interstellar formaldehyde (H2CO) has been discovered by a group working with the 140-foot radio telescope at Green Bank, W. Va. They observed the molecule in absorption against many galactic and extragalactic sources. The discovery suggests that all the known ingredients for development of life are present in interstellar space.
