We study a dynamic buyer-seller problem in which the good is information and there are no property rights. The potential buyer is reluctant to pay for information whose value to him is uncertain, but the seller cannot credibly convey its value to the buyer without disclosing the information itself. Information comes as divisible hard evidence. We show how and why the seller can appropriate a su...

BACKGROUND The Ruta graveolens L. is currently used by the Jordanian population systemically for its antispasmodic, diuretic, sedative, and analgesic effects and externally for its antirheumatic effect. OBJECTIVE To study plant effects on the reproductive system and fertility using adult male albino rats with special emphasis on the aggressive behavior and sex behavior. The aqueous extracts o...

Breast cancer is the second cause of cancer‑related deaths in woman and the incidence of the disease has increased worldwide, in part due to improvements in early detection. Several drugs with anticancer effects have been extracted from plants in the last 20 years, many of which are particularly effective against breast cancer cells. In particular, we have become interested in the ethanolic ext...

UNLABELLED Acute Otitis Externa is an inflammation of the outer auditory meatus, and according to popular saying, medicinal plant extracts can be used in its treatment. AIM to assess the in vitro antimicrobial activity of the following plants: Aleolanthus suaveolens; Caryophyllus aromaticus; Cymbopogon citratus; Matricaria chamomila; Pithecellobium avaremotemo; Plectranthus amboinicus and Rut...

Plant catalases exhibit spatial and temporal distribution of their activity. Moreover, except from the typical monofunctional catalase, a bifunctional catalase-peroxidase has been reported. The aim of this study was to investigate whether the leaf and root catalases from six different plant species (Lactuca sativa, Cichorium endivia, Apium graveolens, Petroselinum crispum, Lycopersicon esculent...

INTRODUCTION Regarding chronic nature of epilepsy and its side effects and to access the effective treatment procedures, herbal medicine has received remarkable interest. The aim of this study was to determine the anticonvulsant effects of hydro-alcoholic extract of Anethum graveolens seed on pentylenetetrazol (PTZ) -induced seizure in male mice. METHODS Fifty-six albino male mice were divide...

Ruta graveolens belonging to family Rutaceae has long been traditionally used as a medicinal plant as well as a flavoring agent in food. However, very little data are available on the toxicity of the plant. This report presents evidence on the genotoxic and clastogenic potential of an extract of Ruta graveolens and Ruta 200C, a homeopathic preparation. Various types of chromosomal aberrations w...

Buy prices are puzzling: it makes sense for a seller at auction to set a minimum bidding level (i.e., a reserve price), surely, but a maximum? We explore the use of maximum bidding levels (buy prices) in online auctions and provide a rational explanation for this seemingly irrational auction mechanism. We show that augmenting an English auction with a buy price can improve the seller’s profits ...

Five Indian medicinal plants namely Acorus calamus L, Pelargonium graveolens L, Cymbopogon martini L, Cyambopogon nardus L and Cymbopogon citratus L. were studied for their enzymatic and non enzymatic free radical scavenging properties. Enzymatic ROS scavengers: superoxide dismutase (SOD) and catalase were observed maximum respectively in A. calamus (3.59±0.22 μ mol/min/mg/protein) and P. grave...

Celery (Apium graveolens L.) is one of the most economically important vegetables worldwide, but genetic and genomic resources supporting celery molecular breeding are quite limited, thus few studies on celery have been conducted so far. In this study we made use of simple sequence repeat (SSR) markers generated from previous celery transcriptome sequencing and attempted to detect the genetic d...
