Development of an Oligopeptide Functionalized Surface Plasmon Resonance Biosensor for Online Detection of Glyphosate

open access: yes, 2016
We report a surface plasmon resonance (SPR) biosensor for online detection of glyphosate. The surface of the sensing element is decorated with an oligopeptide, TPFDLRPSSDTR, which is identified by using phage display library. This oligopeptide shows high

Oligopeptide Targeting Sortase A as Potential Anti-infective Therapy for Staphylococcus aureus

open access: yesFrontiers in Microbiology, 2018
Sortase A (SrtA)-catalyzed anchorage of surface proteins in most Gram-positive bacteria is indispensable for their virulence, suggesting that this transpeptidase is a promising target for antivirulence therapy.

Impact of Gut Microbiota Metabolites on Serotonin Levels in Irritable Bowel Syndrome

open access: yesGut Medicine, EarlyView.
ABSTRACT Gut microbiota and their metabolites have been proposed as possible etiological factors in irritable bowel syndrome (IBS), and studies suggest that IBS is associated with impaired serotonin synthesis and release. Microbial metabolites are produced through biological pathways and enzymatic processes via gut microbiota.

Iron Fertilization of Soybean Genotypes Differing in Iron Use Efficiency Under Alkaline Conditions: Implications for Yield and Seed Nutritional Quality

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Soybean, a nutritionally important protein‐ and oil‐rich legume, is highly sensitive to iron (Fe) deficiency under alkaline conditions, where reduced Fe availability limits growth, yield, and seed quality. Effective biofortification therefore requires increasing seed Fe while reducing phytate that restricts Fe bioavailability.
