Mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN) is defined as a tumor composed of cells originating from neuroendocrine in the embryonic intestine and elements epithelial adenocarcinoma. To determine differentiation grade MiNEN, proliferation index was used, for which at least 500 were examined. MiNEN rare that most frequently found lower gastrointestinal tract. We present clinical case ...

A total 2400 hatching eggs were obtained from Japanese quails breeders ranged from 100 to 150 days of age used to analyze the effect of shell color on fertility, hatchability, embryonic mortality and malposition as well as internal and external egg quality. Results revealed that shell color had significant effect on fertility and scientific hatchability while it doesn't affect commercial hatcha...

BACKGROUND Knowledge of the relationship between accumulated thermal units and developmental stages of Chinook salmon embryos can be used to determine the approximate date of egg fertilization in natural redds, thus providing insight into oviposition timing of wild salmonids. However, few studies have documented time to different developmental stages of embryonic Chinook salmon and no reference...
