We bring to the lab the theoretical result of Robinson (1985, RAND Journal of Economics 16: 141 145) that collusion is incentive compatible in the English auction (EN) and not in the firstprice sealed-bid auction (FP) in the case of one-shot interaction. Our data partly confirm Robinson’s prediction: in FP all cartels break down, but a majority of cartels breaks down in EN as well. However, mor...

background: diabetes is considered as one of the most common chronic disease. studies show that diabetes decreases the activity of antioxidant enzymes. the purpose of this study was to examine the effect of the alcoholic extract of juglans regia leave on brain antioxidant enzymes in streptozotocin-induced diabetic rats. materials and methods: in this study, adult male wistar rats (n=40, weight ...

Background: Increase of blood glucose leads to structural and functional changes in various target tissues and organs. Gonadal dysfunction and decrease in testosterone production are the consequence of diabetes and these conditions lead to insufficient production of spermatozoids. Besides the use of chemical agents, herbal medications for treatment and reduction of diabetic side effects have be...

The expressed sequence tag (EST) database represents a potentially valuable resource for the development of simple sequence repeat (SSR) markers for use in evolutionary studies. EST-SSRs reveal polymorphisms not only within the source taxon, but in related taxa as well. In this paper, we describe a case study in which the publicly available walnut (Juglans regia) EST database was used to develo...

INTRODUCTION Staphylococcus epidermidis is one of the most frequent causes of biofilm-associated infections on indwelling medical devices. With the emergence of methicillin-resistant S. epidermidis (MRSE), there is an urgent need to discover novel active agents against a range of Gram-positive pathogens. We screened the clinical isolates of S. epidermidis for susceptibility/resistance against c...

BACKGROUND Walnut (Juglans regia L.), that belongs to the Juglandaceae family, is one of the nuts commonly found in Chinese diets. Researchers had obtained peptides from walnut protein hydrolysates, and these peptides exhibited the high antioxidant activities. The objective of this study was to develop a simple and convenient method for a facile and reproducible preparation of antioxidant pepti...
