Front Mol Neurosci. 2014 Aug 22;7:75. doi: 10.3389/fnmol.2014.00075. eCollection 2014.

Thus far, three related natriuretic peptides (NPs) and three distinct sub-types of cognate NP receptors have been identified and characterized based on the specific ligand binding affinities, guanylyl cyclase activity, and generation of intracellular cGMP. Atrial and brain natriuretic...

Dietary glucose regulates yeast consumption in adult Drosophila males.

Frontiers in physiology

Lebreton S, Witzgall P, Olsson M, Becher PG.
PMID: 25566097
Front Physiol. 2014 Dec 22;5:504. doi: 10.3389/fphys.2014.00504. eCollection 2014.

The adjustment of feeding behavior in response to hunger and satiety contributes to homeostatic regulation in animals. The fruit fly Drosophila melanogaster feeds on yeasts growing on overripe fruit, providing nutrients required for adult survival, reproduction and larval growth....

Peptide utilizing carbon starvation gene yjiY is required for flagella mediated infection caused by Salmonella.

Microbiology (Reading, England)

Garai P, Lahiri A, Ghosh D, Chatterjee J, Chakravortty D.

This study was conducted to investigate the protein adducts with pesticides in a cohort of 172 factory workers that were exposed to a mixture of pesticides. The 35 samples showing considerable variation in biochemical parameters, i.e., butyrylcholinestrase (BChE), serum...

High performance liquid chromatography (HPLC) fingerprints and primary structure identification of corn peptides by HPLC-diode array detection and HPLC-electrospray ionization tandem mass spectrometry.

Journal of food and drug analysis

Wang C, He H, Zhang JL, Li X, Ma ZL.
PMID: 28911415
J Food Drug Anal. 2016 Jan;24(1):95-104. doi: 10.1016/j.jfda.2015.05.005. Epub 2015 Jul 22.

Corn peptides (CPs) are reported to have many biological functions, such as facilitating alcohol metabolism, antioxidation, antitumor, antihypertension, and hepatoprotection. To develop a method for quality control, the high-performance liquid chromatography (HPLC) system was applied. Twenty-eight common peaks were...

Biologically active peptides: Processes for their generation, purification and identification and applications as natural additives in the food and pharmaceutical industries.
