How do herd’s genetic level and milk quality affect performance of dairy farms?
genetic level dairy farm technical efficiency data envelopment analysis fractional regression model
2018/11/23
The effects of genetic level and output quality characteristics on technical efficiency (TE) of dairy farms were studied. The average total relative breeding value (RBV) at herd level was considered a...

2016/5/23
DsRed, a tetrameric fluorescent protein cloned from the Discosoma genus of coral, has shown promise as a longer-wavelength substitute for green fluorescent protein (GFP) mutants for in vivo protein la...
Serum aminotransferases in nonalcoholic fatty liver disease are a signature of liver metabolic perturbations at the amino acid and Krebs cycle level
fatty liver gene expression liver injury metabolomics transaminases
2018/11/27
Background: Extensive epidemiologic studies have shown that cardiovascular disease and the metabolic syndrome (MetS) are associated with serum concentrations of liver enzymes; however, fundamental cha...
Effect of dietary eicosapentaenoic and docosahexaenoic acid on expression of rat liver genes controlling cholesterol homeostasis and on plasma cholesterol level
PPARα SREBP-2 Insig-1
2015/7/2
A hypothesis that eicosapentaenoic acid + docosahexaenoic acid (EPA+DHA) lower plasma cholesterol via increased expression of the Insig-1 gene with ensuing decrease of expression of genes coding for 3...

Ethylene is one ofthe classical plant hormones with a diverse function in plant growth and development. Root elongation is sensitive to ethylene such that treatments with ethylene and the ethylene pre...
Evaluation of the transfer of Listeria monocytogenes: A study at the macroscopic and cellular level
Monocytes liszt high density polyethylene biofilms cells the nucleus of the cell
2015/1/28
The objective of this work was to study parameters involved in the transfer of Listeria monocytogenes from surfaces to foods and vice versa. We evaluated the influence of surfaces (stainless steel and...
