Freezing of water in dormant vegetative apple buds in relation to cryopreservation.
Various empirical prefreezing protocols have been used to facilitate cryopreservation of dormant buds from woody plants. The objective of this research was to determine the quantity of water remaining in liquid phase, under different prefreezing conditions using pulsed nuclear magnetic resonance spectroscopy of dormant apple (Malus domestica Mill.) buds from three cultivars. During prefreezing,...
متن کاملLiquid Nitrogen Storage of Haemoglobin Variants.
Received for publication 26 April 1963. is thawed immediately after freezing a precipitate of denatured protein can be seen in the solution. We have recently been investigating the storage of human red cells in liquid nitrogen for serological purposes (Huntsman, Hum, Ikin, Lehmann, and Liddell, 1962). We thought that this technique might be useful for the preservation of haemoglobin as well as ...
متن کاملEstablishment of canine models of lunatomalacia through liquid nitrogen freezing
The aim of this study was to investigate the feasibility of establishing dog models of lunatomalacia through liquid nitrogen freezing. Twelve adult crossbred dogs were divided into three groups. Unilateral lunates were peeled off the parenchyma and frozen to result in avascular necrosis. They were observed dynamically through X-ray, computed tomography (CT) and magnetic resonance imaging (MRI)....
متن کاملMorphology of heart valves preserved by liquid nitrogen freezing.
As a preliminary to establishing a frozen valve bank for replacement surgery, the possible effects of the proposed freezing and thawing procedure on tissue structure were assessed in 16 human pulmonary valves removed from cadavers at necropsy and nine dog valves obtained fresh. The valves were frozen and stored in liquid nitrogen for intervals ranging from 23 to 380 days. Blocks of tissue cut f...
متن کاملFreezing and Storing Ditylenchus dipsaci in Liquid Nitrogen.
After 18 months of storage at -150 C, some larvae of Ditylenchus dipsaci, which had been treated in a 7.5% solution of dimethyl sulphoxide and cooled to -25 C before storage, were still viable on thawing. Some survivors penetrated and developed normally in stems of alfalfa seedlings. Tests showed that active larvae could be frozen directly, thus eliminating the need to use the quiescent stage o...
