Cryogenic scanning electron microscopy (cryo-SEM) was used to investigate microstructure development of composite coatings prepared from dispersions of antimony-doped tin oxide (ATO) nanoparticles (approximately 30 nm) or indium tin oxide (ITO) nanoparticles (approximately 40 nm) and latex particles (polydisperse, D(v): approximately 300 nm). Cryo-SEM images of ATO/latex dispersions as-frozen s...

For the comparative study of liquid and frozen plasma, 3 fresh pools of plasma were prepared by the Blood Plasma Department of the U. S. Naval Medical School, Washington, D. C. One half of each pool was transferred to small containers holding 200 ml. of citrated plasma and immediately frozen at -30° C. The other half was kept in similar containers in the liquid state at room temperature. At pre...

Song J.-F., Liu C.-Q., Li D.-J., Meng L.-L. (2013): Effect of cooking methods on total phenolic and carotenoid amounts and DPPH radical scavenging activity of fresh and frozen sweet corn (Zea mays) kernels. Czech J. Food Sci., 31: 607–612. We evaluated the effect of three different cooking methods on antioxidant content and radical scavenging activity of sweet corn. Both fresh and frozen sweet ...

When poultry manure is collected but cannot be analyzed immediately, a method for storing the manure is needed to ensure accurate subsequent analyses. This study has 3 objectives: (1) to investigate effects of 4 poultry manure sample preservation methods (refrigeration, freezing, acidification, and freeze-drying) on the compositional characteristics of poultry manure; (2) to determine compositi...

Frozen section diagnosis is a highly useful method of diagnosis. There were 4434 frozen sections, 24 false positive diagnosis, 65 false negative diagnosis and 30 deferred diagnosis. This method achieves the highest accuracy when there is a cooperation between experienced surgeon and reliable and careful pathologist. It is wise to defer the diagnosis of consult to other pathologist in difficult ...

Introduction Primary breeders are currently faced with the same problem plaguing most animal industries, rising production costs. Labor, feed and energy costs are forcing primary breeders to consider more economical ways of maintaining gene pools. One way to reduce such costs is with the use of frozen semen. With frozen semen available from superior sires, primary breeders will have the tool to...

Objective To analyse factors influencing the outcome of frozen-thawed embryo transfer (FET) Method A retrospective analysis was performed in our center on 129 thawing cycles from March 2001 to April 2003. The related parameters were compared between conceived and non-conceived cycles. Results There were totally 129 clinical pregnancies in these transfers (pregnancy rate: 27.1%). Frozen-thawed e...

During spring, summer and winter seasons, Sistani donor cows, with normal reproductive status, were superovulated and embryos were recovered non-surgically on day 7. Grade A blastocyst embryos were either transferred fresh (spring) or frozen (summer and winter). Recovered embryos during summer and winter were exposed to glycerol and frozen using conventional method. During spring season, recipi...
