ferulago w. koch. (apiaceae) genus is represented by approximately 50 taxa throughout the world. ferulago species are known as “çakşır” or “çağşır” in turkey and mostly known for their aphrodisiac effects. however recent reports emphasize the activity of various ferulago species against cancer, as well. the aim of this study was to investigate the effect of lyophilized extract of f. mughlea peş...

Staphylococcus aureus phage ISP was lyophilized, using an Amsco-Finn Aqua GT4 freeze dryer, in the presence of six different stabilizers at different concentrations. Stability of the lyophilized phage at 4 °C was monitored up to 37 months and compared to stability in Luria Bertani broth and physiological saline at 4 °C. Sucrose and trehalose were shown to be the best stabilizing additives, caus...

Experience in the management of 77 isolated orbital floor fractures is presented. The transconjunctival approach was used exclusively to access the orbital floor and lyophilized dura and cartilage were used to reconstruct the floor, when indicated. Follow-up for an average of 36 months showed excellent cosmetic and functional results. A 20% complication rate was noted, which compares favorably ...

In Sicily folk medicine, Opuntia ficus indica (L.) Mill. cladodes are used for the treatment of gastric ulcer. We studied the effect of administration of lyophilized cladodes on experimental ethanol-induced ulcer in rat. In this paper, we report the ultrastructural observations of gastric mucosa. The ultrastructural changes were observed by trasmission electronic microscopy (TEM) confirming the...

Current quality control of assays of acid phosphatase (EC 3.1.3.2) with thymolphthalein substrate is inadequate when certain control-suppliers' instructions are followed for reconstituting and stabilizing human lyophilized control material. If such materials are reconstituted with a citric acid solution, then stored frozen, control vial-to-vial variability is minimized, as are losses of activit...

Although lyophilization reduces the bacterial population in plasma, some species survive for several months. Sensitivity or resistance to lyophilization in plasma is a characteristic of each morphological type, with gram-negative species being more sensitive to destruction than cocci or sporulating gram-positive species. Reconstituted preparations of lyophilized plasma must be incubated for 24 ...

A colorimetric sulfo-phospho-vanillin (SPV) method was used to validate a high throughput method for total lipids analysis in fresh and lyophilized oleaginous microorganisms. This method uses a small amount of biological material, does not require a lot of sample manipulation, can be automated, is reproducible and easy to implement. A 96-well microplate SPV assay allows one to determine quickly...
