Human granulocytes (PMNL) were successfully cryopreserved for up to 14 months. The PMNL (1-2 X 10(7)/ml) were stored in 2-ml ampoules in the gas phase of liquid nitrogen at a temperature between -160 degrees C and -196 degrees C using dimethylsulphoxide (DMSO 10%) as cryoprotectant. Morphology and phagocytic and bactericidal capacity were best preserved by adding fetal calf serum to the freezin...

In this study, sulfonated carbon cryogel (CC) doped with zinc was prepared and used as a solid catalyst. Carbon by mixing urea furfural, freeze-drying, calcination. The CC then impregnated (II) nitrate for ethyl levulinate production from ethanolysis of glucose. Experiment results showed that different types catalyst precursor had catalytic effects on the Sulfonated (SCC-Zn) which at calcinatio...

Probiotic formula for the vaginal tract must contain high numbers of viable beneficial bacteria that maintain their characteristics during production and further storage, in order to exert claimed probiotic effect. Four strains—Lactobacillus gasseri CRL1320, Limosilactobacillus reuteri CRL1324, Ligilactobacillus salivarius CRL1328 Lacticaseibacillus rhamnosus CRL1332—originally isolated from va...

Lentiviral technology has proven to be a powerful tool to express exogenous genes in dividing and non-dividing cells. Currently, most protocols for generating high-titer lentivirus require ultracentrifugation, which can be an instrumental barrier for routine operations in a laboratory. In this study, the effect of relative centrifugal force (RCF) on the concentration efficiency of the lentiviru...

background: vibrio paraheamoloyticus is one the causative agents of vibriosis with high mortality in farmed fish and shrimp and under predisposing conditions.                                  objectives: this study was aimed to assess the effect of gamma irradiation on the inactivation of v.  paraheamoloyticus under fresh and freeze-dried conditions. methods: vials of 0.5 ml fresh culture of th...

The functional properties of alkali soluble chicken meat protein/starch blend were studied in three phases. In the first phase chicken breast meat powder was solubilized with alkali in a 2  2 factorial experiment. The results from microscopic appearance, microscopy, SEM, consistency, solubility, X-ray diffractometry, SDS-Page showed changes in microstructural, textural and molecular weight of ...

in order to improve food texture, hydrocolloids are used widely as gelling material in food systems. wild sage seed has remarkable amounts of gum (mucilage) with good functional properties. this mucilage also improves the rheological, textural and functional properties of foods. in this study the effects of different drying methods including hot air drying (40, 50, 60, 70 and 80°c), freeze dryi...
