Gallic acid (GA) is the main phenolic antioxidant which has been subjected of many studies because of its important biological properties including anticancer, anti-inflammatory and antimicrobial activities as well as free radicals scavenger and cardiovascular diseases protector. Hereupon, fabricating a selective and sensitive sensor for GA detection and measurement is an important issue. In th...

Background: The death of neurons and cerebral edema are the main consequences of stroke. However, inflammatory processes play a key role in aggravating cerebral damage following stroke. The aim of this study was to investigate the effects of Viola odorant extract (VOE) on infarct volume (IV), neurologic deficits (ND), and expression of NF-κB and VCAM-1 in the MCAO model. Method: The animals we...

OBJECTIVES To determine the antibacterial activity of small cyclic plant proteins, i.e. cyclotides, and the importance of the surface exposed charged residues for activity. METHODS Prototypic cyclotides, including the Möbius kalata B1 and the bracelet cycloviolacin O2 (cyO2), were isolated using reversed-phase HPLC. Initial activity screenings were conducted using radial diffusion assays (RDA...

Myrmecochorous diaspores bear a nutrient-rich appendage, the elaiosome, attractive to ant workers that retrieve them into the nest, detach the elaiosome and reject the seed intact. While this interaction is beneficial for the plant partner by ensuring its seed dispersal, elaiosome consumption has various effects -positive, negative or none - on ants' demography and survival, depending on both t...

Density, distribution, and nutritional quality of plants are the causal basis of host plant selection in aphids. Nutritional qualities of a plant vary according to its growth stage and also in response to seasonal variation. How host plant growth stages shape aphid performance was studied in Aphis spiraecola Patch (Homoptera: Aphididae) on the perennial Siam weed, Chromolaena odorata (L.) King ...
