quail-chick marker system
We have used the quail-chick chimera system to reveal the cell migrations and settling pattern involved in the construction of the cerebellum. Three types of orthotopic transplantations were carried out, between quail and chick embryos, at the 12-somite stage: exchanges of (i) the whole metencephalic vesicle, (ii) the lateral half of this vesicle and (iii) the diencephalic plus the mesencephali...

The use of noninvasive methods for measuring fecal glucocorticoid metabolites is a useful tool for endocrine assessment particularly in studies where animals cannot be captured, when they should be sampled without disturbing their activities, and/or when welfare needs to be maximized.

We identified sequences from known and novel species from the viral families Circoviridae, Parvoviridae, Picornaviridae, Reoviridae, Adenovirus, Astroviridae,...
متن کاملMaking Decision Support System for Utilization of Biogas in Iran

Biogas utilization is a one of these promising options that can mitigate these problems since biogas is produced by the fermentation of waste, so is rich in methane and has the same characteristics as natural gas. Biogas has increasingly been noticed in different co...
متن کاملThermophilic and thermotolerant fungi in poultry droppings in Nigeria.
Ten species of fungi were obtained from poultry droppings in Nigeria. Six of these are true thermophiles while the other four are thermotolerant. Aspergillus fumigatus Fresenius, Mucor pusillus Lindt and Thermoascus aurantiacus Stolk are known human pathogens. Except for M. pusillus, all the thermotolerant species had a higher occurrence at 45 degrees C while the thermophilic varieties were rea...
