Trust is vital for market development, but how can trust be enhanced in an online marketplace? A common view is that more trusting of buyers may help to build seller trustworthiness. This paper highlights a possibility that encouraging buyer trusting may lower seller trustworthiness in equilibrium. In particular, we set up a rational expectation model in which a marketplace uses buyer protectio...

Background: Apium graveolens has been used in Unani system of medicine as anti inflammatory, uricosuric, diuretic, carminative, antidyslipidemic, abdominal discomfort etc.The aim of the present study was to determine the antispasmodic activity of A. graveolens in Guinea Pigs against histamine induced contractions. Materials and Methods: Antispasmodic activity of PEESAG at the doses of 100, 200,...

If bidders have independent private values and homogeneous entry costs, a firstor secondprice auction with a reserve price equal to the seller’s value maximizes social surplus and seller revenue. We show that if entry costs are heterogeneous and private information, then the revenuemaximizing reserve price is above the seller’s value, a positive admission fee (and a reserve price equal to the s...

Enantioselective hydrolysis of bromo- and methoxy-substituted 1-phenylethanol acetates was conducted using comminuted carrot (Daucus carota L.) and celeriac (Apium graveolens L. var. rapaceum) roots. Hydrolysis of the acetates led to alcohols, preferentially to R-(+)-enantiomers. Efficiencies of both reactions - hydrolysis of the acetates with an electron-donating methoxy group and oxidation of...

This Commentary discusses the work of Neudecker et al. in this issue of the Biochemical Journal in which site-directed mutagenesis and NMR spectroscopy have been used to analyse in detail the IgE-binding capacity of two cross-reactive allergens: Apg1.0101 from celery ( Apium graveolens ) and Pru av 1 from cherry ( Prunus avium ), which are both members of the pathogenesis-related allergen famil...

A celery petiole phloem cDNA library was constructed and used to identify a cDNA that gives Saccharomyces cerevisiae cells the ability to grow on mannitol and transport radiolabeled mannitol in a manner consistent with a proton symport mechanism. This cDNA was named AgMaT1 (Apium graveolens mannitol transporter 1). The expression profile in source leaves and phloem was in agreement with a role ...

apigenin is best known as an irreversible inhibitor of monoamine oxidase (mao), an intracellular enzyme associated with the outer membrane of mitochondria. the purpose of this study is to establish a reliable and quick method for the assignment of apigenin in cosmos bipinnatus, apium graveolens and petroselinum crispum by high performance liquid chromatography with ultraviolet detection (hplc-u...
