An identity links the rate of economic growth, the speed of poverty reduction and changes in the distribution of income during some time period in a given country. A few authors used that identity to understand the causes for observed changes in poverty and to identify the exact role of economic growth in poverty reduction. Yet, many empirical cross-country studies of the relationship between g...
توالی های تک رشته DNA یا RNA که تحت عنوان آپتامر شناخته می شوند قادرند مولکول هدف را با اختصاصیتی در حد آنتی بادی های مونوکلونال ردیابی نمایند. با این وجود قرار گیری مایکوتوکسین ها در گروه مولکول های کوچک و تفاوت بالای وزن مولکولی آنها با توالی های آپتامری تبدیل به چالشی جدی در معرفی پروب های آپتامری برای آنها شده است. در بررسی حاضر با هدف دستیابی به توالی آپتامری جدید و کوتاه تر برای آفلاتوکسی...
NUT midline carcinoma (NMC) is a uniformly lethal malignancy that is defined by rearrangement of the nuclear protein in testis (NUT) gene on chromosome 15q14. NMCs are morphologically indistinguishable from other poorly differentiated carcinomas, and the diagnosis is usually made currently by fluorescence in situ hybridization (FISH). As normal NUT expression is confined to testis and ovary, we...
To address the question how the recognition helix of the LexA repressor is positioned within the major groove of operator DNA we have applied a site-specific photocrosslinking approach using a LexA mutant repressor (LexA-C52) that harbors a single cysteine side chain in position 52, close to the COOH terminus of helix 3. The LexA-C52 mutant repressor has been purified and modified site-specific...

A number of authors have suggested that economies face a long-run inflation-unemployment trade-off due to downward nominal-wage rigidity. This theory has implications for the nature of the short-run Phillips curve when wage inflation is low. Akerlof, Dickens and Perry have developed an empirical model in which a variable (S) designed to capture the effect of downward nominal-wage rigidity is co...

This article adds technology choice to a free-entry Cournot model with linear demand and constant marginal costs. Firms can choose from a discrete set of technologies. This simple framework yields non-existence of equilibrium, existence of multiple equilibria and equilibria in which ex-ante identical ̄rms choose di®erent technologies as possible outcomes. I provide a full characterization of th...
The plant microbiome represents an enormous untapped resource for discovering novel genes and bioactive compounds. Previously, we isolated Pseudomonas sp. SH-C52 from the rhizosphere of sugar beet plants grown in a soil suppressive to the fungal pathogen Rhizoctonia solani and showed that its antifungal activity is, in part, attributed to the production of the chlorinated 9-amino-acid lipopepti...
