Sperm freeze-drying; effects on sperm parameters
Today, sperm cryopreservation is a routine practice in infertility clinics. One of the alternative methods to preserve sperm is freeze-drying. This process consists of three steps. The first step is sample freezing, during which the solvent is separated from the solvent. Water forms ice crystals and the solute is placed between the ice crystals. Freezing may be done in a separate device or in a...
متن کاملA Comparative Study on Drying and Coating of Osmotic Treated Apple Rings
In this study, the effect of edible coat (carboxy methyl cellulose) before osmotic dehydration anddifferent drying methods on sensory and physical properties of dried apple (V. Golden delicious)rings was investigated. The coated and non-coated samples pretreated with 50% sucrose osmoticsolution and dried in freeze drier (-40 to -50°C, 0.026-0.017 mbar, 24 hr), vacuum drier (70°C, 200mbar, 8-10 ...
متن کاملStability of prothrombin and factor VII in freeze-dried plasma.
The stability of prothrombin and factor VII was studied using accelerated degradation tests in three preparations of freeze-dried pooled normal plasmas. In a previous report (Brozović, Gurd, Robertson, and Bangham, 1971) factor X was shown to be relatively unstable in these preparations of freeze-dried plasma: it was calculated that up to 8% of the original factor X activity would be lost after...
متن کاملModeling and Optimization of Ultrasound-Assisted Osmotic Dehydration with Finished Freeze Drying on Black Cherries – The Effect on Antioxidant Activities
ABSTRACT: In this study, response surface methodology was used to optimize ultrasound osmotic pretreatment with finished freeze drying of black cherries. Freeze drying is a separation process based on the sublimation phenomenon. This process has the following advantages as compared to the conventional drying process, maintenance of the structure, moisture removal at low temperature (reduced tr...
متن کاملOutermost-cell-surface changes in an encapsulated strain of Staphylococcus aureus after preservation by freeze-drying.
The effects of drying time during freeze-drying on the outermost cell surface of an encapsulated strain of Staphylococcus aureus S-7 (Smith, diffuse) were investigated, with special attention paid to capsule and slime production. To quantify capsule and slime production, capsule antigen production and cellular characteristics such as growth type in serum-soft agar, cell volume index, and clumpi...
