Annual and perennial high‑Andes species have a contrasting freezing‑resistance mechanism to cope with summer frosts
In high-mountain habitats, summer frosts have negative consequences for plant fitness, therefore high-mountain plants have developed mechanisms of avoidance and tolerance to cope with freezing temperatures. Various ...
The influence of freezing rates on bovine pericardium tissue Freeze-drying
The bovine pericardium has been used as biomaterial in developing bioprostheses. Freeze-drying is a drying process that could be used for heart valve's preservation. The maintenance of the characteristics of the biomaterial ...
Freezing point and thermal conductivity of tropical fruit pulps: Mango and papaya
The freezing point depression of mango and papaya pulps was measured by using a simple apparatus, consisting of two major sections: a freezing vessel and a data acquisition system. The thermal conductivity of both pulps ...
Freeze-drying microscopy in mathematical modeling of a biomaterial freeze-drying
(UNIV SAO PAULO, CONJUNTO QUIMICASSAO PAULO, 2012)
Transplantation brings hope for many patients. A multidisciplinary approach on this field aims at creating biologically functional tissues to be used as implants and prostheses. The freeze-drying process allows the fundamental ...
Care during freeze-drying of bovine pericardium tissue to be used as a biomaterial: A comparative study
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011)
Bovine pericardium (BP) tissue is widely used in the manufacture of bioprosthetics. The effects of freeze-drying on the BP tissue have been studied by some researchers in order to decrease their cytotoxicity due to ...
RAPD and freezing resistance in Eucalyptus globulus
(Pontificia Universidad Católica de Valparaíso, 2006)
Moisture sorption isotherm characteristics of freeze-dried D-limonene emulsions in modified chitosan and maltodextrin
(TAYLOR & FRANCIS INC, 2008)
This article reports on modified chitosan as an alternative substance for protecting loss of volatile compounds during freeze drying. Moisture sorption isotherms of freeze-dried D-limonene emulsions in modified chitosan ...
Effect of protective agents and previous acclimation on ethanol resistance of frozen and freeze-dried Lactobacillus plantarum strains
(Academic Press Inc Elsevier Science, 2015-11)
The aim of this work was to study the protective effect of sucrose, trehalose and glutamate during freezing and freeze-drying of three oenological L. plantarum strains previously acclimated in the presence of ethanol. The ...
